DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described below based on the accompanying drawings.

First Embodiment

[0030] FIG. 1 is an overall perspective view of a connector of the present embodiment, which illustrates a state in which the movable member is in an open position when a flat conductor is not inserted (before inserting). FIG. 2 is a perspective view taken along a terminal position of the connector in FIG. 1. FIG. 3 is a perspective view when the movable member is in a closed position in the connector in FIG. 2. Furthermore, FIGS. 4(A) to 4(C) are cross-sectional views illustrating a cross section in various states.

[0031] In FIG. 1 through FIG. 3, a connector 1 has a metal plate terminal 10, a metal fitting 20, a housing 30 for retaining the terminal 10 and metal fitting, and a movable member 40 that can rotate and move with regard to the housing 30.

[0032] The terminal 10 maintains a flat surface of a metal plate, forms a plate surface parallel to a paper surface as seen in FIG. 4(A) illustrating a state in which the movable member 40 is in an open position, and has a pressing arm part 11 extending in a lateral direction (left and right direction of the paper surface) at an upper position, a supporting arm part 12 extending in the lateral direction similar to the pressing arm part 11 at a lower position, and a connecting part 13 connecting both at an intermediate position thereof.

[0033] The pressing arm part 11 has an upper front arm part 11A of a portion more forward (right side in the drawing) than the connecting part 13, and an upper rear arm part 11B of a portion more rearward (left side in the drawing) than the connecting part 13. After the upper front arm part 11A is tilted upward toward a position more forward than an upper end position of the connecting part 13, it is extended forward substantially as is, and thus a concave pressure receiving part 11A-1 is formed on a lower edge at a position near a front end of the upper end arm part 11A. In contrast, the upper rear arm part 11B forms an upper bulging part 11B-1 where a rear end portion thereof is raised upward, the rear end (left end) has a rear end protruding part 11B-2 protruding rearward with an upper edge as a tapered part and a lower edge as a horizontal part, and thus the lower edge is formed as a regulated part 11B-3 for contacting a regulating part 31B described later. The upper bulging part 11B-1 has a pressing part 11B-4 protruding downward forming an essentially triangular shape at a frontward position adjacent to the regulated part 11B-3 at a lower edge thereof.

[0034] The pressing arm part 11 has elasticity and a relatively small width (upper and lower direction width) in the vicinity of the connecting part 13, and elastic displacement is possible so as to be tilted in the form of a lever with the connecting part 13 as a fulcrum.

[0035] The supporting arm part 12, provided in parallel facing the pressing arm part 11 below the pressing arm part 11, has a lower front arm part 12A of a portion more frontward than the connecting part 13 and a lower rear arm part 12B of a portion more rearward than the connecting part 13. The lower front arm part 12A has a cam supporting part 12A-1 rising from an immediately forward position with regard to the connecting part 13, and protruding in a trapezoidal shape extending forward, and a connecting part 12A-2 protruding forward at a lower portion of a front end position of the cam supporting part 12A-1. The cam supporting part 12A-1 is positioned below the pressure receiving part 11A-1 formed on the upper front arm part 11A of the pressing arm part 11, opposes the pressure receiving part 11A-1, and extends in a straight form forward and rearward including the opposing position thereof. Furthermore, the connecting part 12A-2 has a lower edge positioned at a level protruding slightly below or at the same level as a bottom surface of the housing 30 described later, and a surface of the lower edge is solder connected to a circuit member (not illustrated in the drawing) to form a solder connecting surface 12A-2A. The connecting part 12A-2 has a securing groove 12A-2B forming a curved groove formed on a rear edge thereof, and functions for securing and attaching to the housing 30 such that the securing groove 12A-2B mates to a front end securing part 32A provided on the housing 30. Note that a right end flange of the connecting part 12A-2 is an edge part separated from a carrier in order to form a completed product from a semi-completed product state where a terminal is connected to a carrier (not illustrated in the drawing).

[0036] The lower rear arm part 12B of the supporting arm part 12 extends rearward from a position of the connecting part 13, which reaches a position slightly more in front of the regulated part 11B-3 of the pressing arm part 11, in other words, a position slightly more forward than the regulated part 11B-3 in a front and rear direction. A locking protrusion 12B-1 that protrudes upward so as to bite into an intermediate securing part 37, which is provided on the housing and will be described later, is provided on the lower rear arm part 12B in a directly rearward position to the connecting part 13, and a supporting part 12B-2 that protrudes upward, in a vertical direction opposing the pressing part 11B-4 of the pressing arm part 11 in the front and rear direction, is provided on a rear end. An interval between the supporting part 12B-2 and pressing part 11B-4 is set to have a wider thickness dimension than the thickness dimension of a flat conductor F when the terminal 10 is in a free state, in other words, when the flat conductor F (refer to FIG. 4(C)) is not inserted.

[0037] A plurality of the terminals 10 formed thereby are retained by the housing 30 at predetermined intervals in a connector width direction which is the lateral direction sloping down toward the right in FIG. 1 through FIG. 3 (a direction orthogonal to the paper surface in the views of FIGS. 4(A) to 4(C)).

[0038] The housing 30, which retains the terminals 10 and is made of an electrical insulating material, has an upper wall 31 and lower wall 32 that span a wider range than that of the terminal array, a side wall 33 (refer to FIG. 1) that holds the upper wall 31 and lower wall 32 on both ends in the connector width direction, and a partition wall 34 that connects the upper wall 31 and lower wall 32 at a predetermined interval between two side walls 33, and thus forms a flat essentially cuboid outer shape.

[0039] The upper wall 31 has formed therein a notched part 31A, which is open frontward in a wide range such that the front portion extends beyond the range of the terminal array in the connector width direction to a position in the vicinity of the side wall 33. In other words, the notched part 31A is also opened upward. The partition wall 34 is also cut off and the housing 30 forms a front opening part 35 in the connector width direction range where the notched part 31A is formed. The front opening part 35 functions as a rotating space and arrangement for the movable member 40 described later.

[0040] A terminal groove 36 extending from the front opening part 35 to the housing 30 in the front and rear direction is formed on the housing 30. A plurality of the terminal grooves 36 are provided at a predetermined arrangement position of the terminal 10, and one terminal groove 36 is configured by forming as a pair an upper groove 36A formed on a lower surface of the upper wall 31 and a lower groove 36B formed on an upper surface of the lower wall 32 opposite therefrom. In other words, the partition wall 34 is formed between adjacent terminal grooves 36 in the connector width direction.

[0041] Provided on each terminal 36, at a position corresponding to the previously described locking protrusion 12B-1 of the terminal 10 in the front and rear direction, is an island-shaped intermediate securing part 37 that connects the partition walls 34 on both sides of the terminal groove 36, and which is positioned between the lower rear arm part 12B of the supporting arm part 12 and the upper rear arm part 11B of the pressing arm part 11 of the terminal 10 in the vertical direction.

[0042] The housing 30 has the receiving part 30A that is opened rearward on a rear part (left part of FIGS. 4(A) to 4(C)) for inserting a flat conductor, which is formed between the upper wall 31 and lower wall 32 in the vertical direction. The receiving part 30A extends in a direction orthogonal to the paper surface in the same drawing so as to penetrate the partition wall 34, and is connected with a plurality of the terminal grooves 36.

[0043] The upper wall 31 has a hook wall part 31C formed into a lateral U-shape hanging downward and then protruding frontward at a rear end thereof, and the wall part protruding frontward at a lower end of the hook wall part 31C forms the regulating part 31B as a rear end receiving part with regard to the pressing arm part 11 of the terminal 10. The regulating part 31B is positioned immediately below the regulated part 11B-3 provided on a rear end of the terminal 10, and regulates the elastic displacement of the regulated part 11B-3 to a predetermined amount.

[0044] The lower wall 32 of the housing 30 extends in the front and rear direction to form a flat plate shape essentially parallel to the upper wall 31, and a front end of the lower wall 32 extends to the vicinity of a front end of the housing 30 and to a rear end of the housing 30 of a rear end of the lower wall 32. The lower wall 32 has a portion positioned below the front opening part 35 of the housing 30 more forward than a front end of the upper wall 31, and in the rear direction, a rear end of the lower wall 32 is positioned to match the rear end of the upper wall 31 in the front and rear direction. A front end (right end) of the lower wall 32 has a lower surface formed in a tapered shape, which forms the tapered front end securing part 32A. The front end securing part 32A is pressed inside the securing groove 12A-2B of the terminal 10 to secure the terminal 10.

[0045] Accordingly, the housing 30, which retains the terminals 10, also holds a metal fitting 20 on both sides beyond the range of the terminal array, as seen in FIG. 1. The metal fitting 20 has a locking part 21B that protrudes and locks into an engaging part (not illustrated in the drawing) with a notched groove shape formed on the flat conductor, and prevents the flat conductor from disengaging after insertion. The metal fitting 20 has essentially the same overall shape as the terminal described above, and when the movable member 40 described later is moved to a closed position, the upper arm part 21 corresponding to the pressing arm part 11 of the terminal 10 is elastically displaced. However, a point of difference with the terminal 10 is, with the metal fitting 20, the locking part 21B does not contact the flat conductor at this time, but protrudes into the engaging part formed as a notched part of the flat conductor, as compared to the pressing part 11B-4 of the terminal 10 that contacts the surface of the flat conductor.

[0046] The shape of a rear end side of the metal fitting 20 having this point of difference will now be described.

[0047] The metal fitting 20 has a protruding locking part 21B with a larger size than the pressing part 11B-4 of the pressing arm part 11 in a shape resembling the pressing part 11B-4 (refer to FIG. 1) that is formed on a rear end of the upper arm part 21 corresponding to the pressing arm part 11 of the terminal at a slightly more rearward position than a rear end of the pressing arm part 11, and a lower arm part 22 extends to a position at the rear end of the housing 30, so as to constitute a straight form up to a position in the vicinity of the rear end of the lower arm part 22. The metal fitting 20 is not a feature of the present invention, and therefore, a further description of the metal fitting 20 is omitted.

[0048] Rear end sides of the terminal 10 and metal fitting 20 formed thereby are positioned on a front opening part 35 of the housing 30, and then faced rearward and pressed into a terminal groove 36 and a metal fitting groove (not illustrated in the drawing), and, in the case of the terminal 10, the locking protrusion 12B-1 provided on a lower rear arm part 12B bites into the intermediate securing part 37 of the housing 30, and the front end securing part 32A of the housing 30 is pressed into a securing groove 12A-2B formed on a lower front arm part 12A, the terminal 10 is inserted into the terminal groove 36 to a predetermined position, thereby allowing for the retention of that position as well as preventing disengagement. The metal fitting 20 is also pressed into a metal fitting groove similar to the terminal 10, and thus disengagement can be prevented at a predetermined position. Note that a slit-shaped clearance groove 38 is formed on the housing 30 in order to enable increasing the elastic displacement upward on a rear end of the upper arm part 21 of the metal fitting 20 (refer to FIG. 1).

[0049] The pressure receiving part 11A-1 formed on a front end part of the terminal 10 as described above, and the movable member 40 that is rotatably supported on a pressure receiving part (not illustrated in the drawing), is similar to the metal fitting 20 and exerts an upward force on the pressure receiving part 11A-1, have a cam part 41 stored in the pressure receiving part 11A-1 as seen in FIG. 4(A). In the same figure, the movable member 40 is formed as a plate-shaped member extending in a direction orthogonal to a paper surface, and is rotatable around the cam part 41 between an open position illustrated in the same drawing and a closed position illustrated in FIG. 4(B) and (C).

[0050] The movable member 40 is formed as a plate member extending in a direction orthogonal to the paper surface in FIG. 4(A) over the entire width of the front opening part 35 of the housing 30 in the connector width direction, and is rotatably supported by the metal fitting 20 and terminal 10 between an open position in FIG. 1, FIG. 2, and FIG. 4 and a closed position in FIG. 4(B) and (C) (a state of being supported by the metal fitting 20 is not illustrated).

[0051] The movable member 40 has a groove part 42 that stores a rear end part in the vicinity of the pressure receiving part 11A-1 of the terminal and a rear end part in the vicinity of the pressure receiving part of the metal fitting 20 in a lower half in an upright state at an open position in FIG. 4(A), the cam part 41 is provided on a lower end of the movable member in the groove part 42. The cam part connects grooved inner walls located on both sides of the groove part 42 in the connector width direction.

[0052] The cam part 41 has a rotating axis part 41A with a curved surface suitable for rotating in the concave pressure receiving part 11A-1 formed on the terminal 10, and a supported part 41B forming an essentially trapezoidal cross section that is long in the lateral direction, protruding and extending laterally from the rotating axis part 41A in FIG. 4(A). A lower edge of the supported part 41B forms a straight edge part 41B-1 with a downward slope toward a rightward direction and a right end forms an edge part 41B-2 extending vertically. For the edge part 41B-2, the cam part 41 rotates in a clockwise direction around the rotating axis part 41A from an open position in FIG. 4(A), and when in a closed position in FIG. 4(B) and (C), the edge part 41B-2 will go above a cam supporting part 12A-1 of the terminal 10. The length in the lateral direction of the cam part 41 in an open position state in FIG. 4(A) is longer than an interval between a groove bottom of the pressure receiving part 11A-1 in the same drawing and an upper edge of the cam supporting part 12A-1, and when the cam part 41 is in a closed state in FIG. 4(B) and (C), the cam part 41 transmits a reaction force from the cam supporting part 12A-1 to the pressure receiving part 11A-1, elastically displaces the upper front arm part 11A of the terminal 10 upward, and widens the interval such that an upright state is achieved. Thus, when the upper front arm part 11A of the terminal 10 is elastically displaced upward, the pressing arm part 11 is displaced in a lever shape with the connecting part 13 as a fulcrum, and thus the upper rear arm part 11B is elastically displaced downward, the pressing part 11B-4 in the vicinity of a rear end thereof moves downward, and the flat conductor F is pressed downward.

[0053] Principles of operation and outlines for use of the connector in the present embodiment are described below based on FIGS. 4(A) to 4(C) of the accompany drawings.

[0054] As seen in FIG. 4(A), when a flat conductor is not inserted (before inserting) into the connector 1, the terminal 10 is in a free state not elastically displaced between the pressing part 11B-4 of the pressing arm part 11 of the terminal 10 and the supporting part 12B-2 of the supporting arm part 12, and therefore, a large interval is maintained and a flat conductor (not illustrated in the drawing) is in a state than can be easily inserted into the receiving part 30A from the left. In this state, the regulated part 11B-3 of the terminal 10 is in a state located above and not contacting the regulating part 31B of the housing 30.

[0055] Next, if the movable member 40 is moved into a closed position inadvertently or in order to store the connector 1 when a flat conductor is not inserted, the cam part 41 of the movable member 40 achieves an upright state, the pressure receiving part 11A-1 of the pressing arm part 11 receives a force directed upward from the cam part 41, and the upper front arm part 11A of the pressing arm part 11 causes elastic displacement such that a front end thereof is raised. The elastic displacement of the upper front arm part 11A is an elastic displacement directed downward based on a lever principle with a position of the connecting part 13 as a fulcrum with regard to the upper rear arm part 11B. However, in the present embodiment, the regulated part 11B-3 is provided on the terminal 10 and the regulating part 31B is provided on the housing 30 so as to be positioned mutually opposing in the vertical direction, and therefore, as seen in FIG. 4(B), while the movable member 40 moves to a closed position, the regulated part 11B-3 contacts the regulating part 31B, and in a state in which the upper rear arm part 11B of the pressing arm part 11 is not elastically displaced any further, the movable member 40 reaches a closed position and only the elastic displacement of the upper front arm part 11A is increased.

[0056] Therefore, even if the movable member 40 receives a movement operation to a closed position when a flat conductor is not inserted, the upper rear arm part 11B of the pressing arm part 11 is regulated midway and does not cause excess elastic displacement, and therefore, when returning to an open position, plastic deformation does not remain as in conventional techniques, and an interval between the pressing part 11B-4 of the terminal 10 and supporting part 12B-2 is not narrowed by plastic deformation but is maintained at a predetermined amount or more. Therefore, when a flat conductor is inserted, the flat conductor can always be smoothly inserted in the receiving part 30A.

[0057] When using the connector, the flat conductor F is inserted in the receiving part 30A. As described above, before the flat conductor F is inserted, an interval between the pressing part 11B-4 and supporting part 12B-2 is sufficiently ensured, and therefore, the flat conductor F is easily inserted into the receiving part 30A to a predetermined position. Thereafter, as seen in FIG. 4(C), when the movable member 40 is moved toward a closed position, the regulated part 11B-3 presses the flat conductor F in a downward direction on pressing part 11B-4 in a state not contacting the regulating part 31B, and the flat conductor F receives a predetermined amount of pressure with regard to the supporting part 12B-2. Thus, the flat conductor F contacts the pressing part 11B-4 and the supporting part 12B-2, and a circuit part of the flat conductor F electrically contacts at least one of the pressing part 11B-4 or the supporting part 12B-2. In FIG. 4(C), when the pressing part 11B-4 presses the flat conductor F, the regulated part 11B-3 and regulating part 31B are in a state not contacting and leaving a gap, and there is no influence on the pressing force of the pressing part 11B-4 with regard to the flat conductor F. Furthermore, it is not required that the regulated part 11B-3 and the regulating part 31B not be in contact, and, as long as a state is ensured in which the pressing part 11B-4 has a sufficient pressing force to press the flat conductor F, the regulated part 11B-3 and regulating part 31B may even be in contact.

Second Embodiment

[0058] Next, a second embodiment of the present invention will be described based on FIG. 5 through FIG. 7. In the previous embodiment, the terminal 10 had an overall shape in which a flat surface of a metal plate was maintained, but the present embodiment is characterized in that the regulated part is formed bent in a plate thickness direction. In FIG. 5 through FIG. 7, only the regulated part of the terminal 10 and the regulating part of the housing 30 are different from the previous embodiment illustrated in FIG. 1 through FIG. 4, and other sites are the same, and therefore, in FIG. 5 through FIG. 7, the same reference codes apply to parts in common with FIG. 1 through FIG. 4, and a description thereof is omitted.

[0059] As seen in FIG. 5 and FIG. 7(A), which illustrates a state in which a movable member is in an open position when the flat conductor F (refer to FIG. 7(C)) is not inserted, the pressing arm part 11 has a portion more rearward than the pressing part 11B-4 bent laterally to form a lateral protruding part 11B-5, and a lower edge of the lateral protruding part 11B-5 is used as a regulated part 11B-6. On the other hand, in the housing 30, a through groove 34A is formed in the front and rear direction on the partition wall 34 on a side where the lateral protruding part 11B-5 is directed, and a portion forming a lower surface of the through groove 34A is formed as a regulating part 34B positioned immediately below the regulated part 11B-6 as a lateral receiving part for receiving the lateral protruding part 11B-5.

[0060] In the present embodiment as described above, when the movable member 40 is moved toward a closed position when the flat conductor F is not inserted, the regulated part 11B-6 contacts the regulating part 34B during the movement, and thus further elastic displacement of the upper rear arm part 11B of the pressing arm part 11 is regulated. The effects brought about by avoiding plastic deformation and behaviors during insertion of the flat conductor F during use due to the regulation is the same as in the previous embodiment. Therefore, at the time of use, a gap is formed between the regulated part 11B-6 and regulating part 34B and both do not contact (refer to FIG. 7(C)). Furthermore, it is not required that the regulated part 11B-6 and the regulating part 34B not be in contact, and, as long as a state is ensured in which the pressing part 11B-4 has a sufficient pressing force to press the flat conductor F, the regulated part 11B-6 and regulating part 34B may even be in contact.

Third Embodiment

[0061] Next, a third embodiment of the present invention is described based on FIGS. 8(A) to 8(C). FIGS. 8(A), 8(B), and 8(C) illustrate a state respectively corresponding to FIG. 4(A), 4(B), and 4(C). The present embodiment is characterized in that a regulated part is not a rear end of a terminal and is provided at an intermediate position in the front and rear direction, and when this point is excluded, the present embodiment is the same as the first embodiment illustrated in FIG. 1 through FIG. 4. Therefore, even in the present embodiment, a terminal is in a shape in which a flat surface of a metal plate is maintained, and in FIG. 8, the same reference codes apply to parts in common with FIG. 4, and a description thereof is omitted.

[0062] With the present embodiment illustrated in FIG. 8(A), in the terminal 10, the pressing part 11B-4 is positioned on a rear end of the pressing arm part 11, a rear end protruding part as the regulated part 11B-3 as illustrated in FIG. 4(A) is not provided therebehind, and a lower edge of a site near the connecting part 13 of the upper rear arm part 11B is used as a regulated part 11B-7. However, an upper surface of the island-shaped intermediate securing part 37 of the housing 30 forms an intermediate receiving part 37A as a regulating part, the intermediate receiving part 37A is immediately below the regulated part 11B-7, and a gap between the regulated parts 11B-7 is defined at a position regulating the elastic displacement to a predetermined amount. The behaviors of the regulating part and regulated part when the flat conductor F (refer to FIG. 8(C)) is not inserted and behaviors during use are as illustrated in FIG. 8(B) and 8(C), and achieve a similar effect to the embodiments described above.
