DETAILED DESCRIPTION OF THE INVENTION

(31) Embodiments of the present invention are described below based on the appended drawings.

Embodiment 1

(32) FIGS. 1 to 3 show a coated conductive wire connecting structure according to Embodiment 1. The coated conductive wire connecting structure is provided to connect a coated conductive wire 21 to a sheet-type conductive member 11 and includes an insulating housing 31. The sheet-type conductive member 11 includes an insulating sheet body 12 that is a piece of cloth, a resin film or the like, and a conductive pattern 13 formed on a surface of the sheet body 12. The coated conductive wire 21 has such a structure that the outer periphery of a conductor part 22 is covered with an insulator part 23.

(33) The housing 31 is in a flat plate shape extending parallel to the sheet-type conductive member 11 and has a sheet-type conductive member insertion opening 32 used for inserting an end of the sheet type conductive member 11 and a housing-side slit (coated conductive wire holding portion) 33 used for inserting the coated conductive wire 21.

(34) For convenience, the plane in which the sheet-type conductive member 11 extends is called XY plane, the direction from the housing 31 toward the sheet-type conductive member 11 is called +Y direction, and the direction being the thickness direction of the housing 31 and perpendicular to the XY plane is called Z direction.

(35) The Y directional end of the sheet-type conductive member 11 is inserted into the sheet-type conductive member insertion opening 32 of the housing 31, and a tip end of the coated conductive wire 21 is, while extending in the Z direction, inserted in the housing-side slit 33 of the housing 31.

(36) As shown in FIGS. 4 and 5, a pressure contact terminal 41 made of metal is accommodated in the housing 31. The pressure contact terminal 41 is electrically connected to the conductive pattern 13 of the sheet-type conductive member 11 and also to the conductor part 22 of the coated conductive wire 21. In other words, the conductor part 22 of the coated conductive wire 21 is electrically connected to the conductive pattern 13 of the sheet-type conductive member 11 via the pressure contact terminal 41 made of metal.

(37) The housing 31 and the pressure contact terminal 41 constitute a coated conductive wire connecting member.

(38) The structure of the housing 31 is shown in FIGS. 6 to 8. The housing 31 in a flat plate shape is provided at its +Y directional end with the sheet-type conductive member insertion opening 32 that opens in three directions, i.e., the +Y, +X and X directions, and at its Y directional end with a pressure contact terminal insertion opening 34 that opens in the Y direction.

(39) The housing-side slit 33 extends in the +Y direction from the Y directional end of the housing 31, opens in the Y direction and communicates with the pressure contact terminal insertion opening 34. The housing-side slit 33 has a slit width W1 in the X direction that is equal to or slightly smaller than the diameter of the coated conductive wire 21.

(40) As shown in FIG. 9, the housing 31 is provided therein with a sheet-type conductive member accommodating portion 35 that communicates with the sheet-type conductive member insertion opening 32 and extends from the +Y directional end of the housing 31 to the middle part, in the Y direction, of the housing 31 along an XY plane. The housing 31 is also provided therein with a pressure contact terminal accommodating portion 36 that communicates with the pressure contact terminal insertion opening 34 and extends from the Y directional end of the housing 31 to the vicinity of the +Y directional end of the housing 31 along an XY plane.

(41) A part of the sheet-type conductive member accommodating portion 35 on the Y direction side and a part of the pressure contact terminal accommodating portion 36 on the +Y direction side overlap each other in the Z direction, and the sheet-type conductive member accommodating portion 35 and the pressure contact terminal accommodating portion 36 communicate with each other in their overlapping part to integrally form a space.

(42) The bottom (inner wall surface) 35A of the sheet-type conductive member accommodating portion 35 on the Z direction side is situated beyond, in the Z direction, the bottom 36A of the pressure contact terminal accommodating portion 36 on the Z direction side, whereby a step portion 37 is formed at the Y directional end of the sheet-type conductive member accommodating portion 35, i.e., in the communicating part where the sheet-type conductive member accommodating portion 35 and the pressure contact terminal accommodating portion 36 communicate with each other.

(43) A groove 38 recessed in the Z direction is formed in the bottom 35A of the sheet-type conductive member accommodating portion 35 at the Y directional end thereof in a position adjacent to the step portion 37.

(44) The sheet-type conductive member insertion opening 32 formed at the +Y directional end of the housing 31 opens in the three directions of +Y, +X and X directions, and as shown in FIG. 10, the sheet-type conductive member accommodating portion 35 communicating with the sheet-type conductive member insertion opening 32 extends across the entire width of the housing 31 in the X direction. That is to say, the sheet-type conductive member accommodating portion 35 opens in the three directions of +Y, +X and X directions. Accordingly, even when the sheet-type conductive member 11 extends for a longer distance than the housing 31 in the X direction, through the insertion of the sheet-type conductive member 11 from the sheet-type conductive member insertion opening 32 toward the Y direction, the sheet-type conductive member 11 is accommodated in the sheet-type conductive member accommodating portion 35 so as to reach the Y directional end of the sheet-type conductive member accommodating portion 35 where the step portion 37 is present.

(45) FIG. 10 shows how the pressure contact terminal accommodating portion 36 communicating with the pressure contact terminal insertion opening 34 formed at the Y directional end of the housing 31 communicates with the sheet-type conductive member accommodating portion 35 via the step portion 37.

(46) The step portion 37 and the groove 38 extend in the X direction throughout the X directional range across which the pressure contact terminal accommodating portion 36 is present.

(47) As shown in FIG. 11, the pressure contact terminal accommodating portion 36 opens only in the Y direction, and the opposite ends of the pressure contact terminal accommodating portion 36 in the X direction are closed by the housing 31. The +Y directional end of the pressure contact terminal accommodating portion 36 is also closed by the housing 31, and an abutment surface 36C extending along an XZ plane is formed at this +Y directional end of the pressure contact terminal accommodating portion 36. A part of the pressure contact terminal accommodating portion 36 extending from the middle part, in the Y direction, of the portion 36 to the +Y directional end thereof overlies the +Z direction side of the sheet-type conductive member accommodating portion 35.

(48) The structure of the pressure contact terminal 41 is shown in FIGS. 12 to 14. The pressure contact terminal 41 is formed from a single metal sheet and includes a flat portion 42 extending along an XY plane and two spring contacts 43. The two spring contacts 43 are formed from an end portion of the metal sheet that is bent from the +Y directional end 42A of the flat portion 42 toward the Y direction and the Z direction, and disposed to be elastically deformable in the Z direction perpendicular to the flat portion 42. The two spring contacts 43 are arranged side by side in the X direction, and a terminal-side slit 44 is formed between those spring contacts 43 to extend from the +Y directional end 42A of the flat portion 42 toward the Y direction.

(49) The terminal-side slit 44 has a slit width W2 in the X direction that is slightly smaller than the diameter of the conductor part 22 of the coated conductive wire 21.

(50) The +Y directional end of the terminal-side slit 44 constitutes a slit opening end 45 communicating with the terminal-side slit 44 and opening in the +Y direction. The slit opening end 45 has a width in the X direction that is larger than the slit width W2 of the terminal-side slit 44 and has a tapered shape with its width in the X direction increasing in the +Y direction.

(51) The flat portion 42 has a width in the X direction that is slightly smaller than the width, in the X direction, of the pressure contact terminal accommodating portion 36 of the housing 31. In a natural state where no force is exerted on either of the spring contacts 43, a distance L2 in the Z direction from the surface of the flat portion 42 on the +Z direction side to the ends of the two spring contacts 43 is set to be larger than a distance L1 in the Z direction from a ceiling surface 36B of the pressure contact terminal accommodating portion 36 of the housing 31 on the +Z direction side to the bottom 38A of the groove 38 on the Z direction side, which is shown in FIG. 9.

(52) Now, the method of connecting the coated conductive wire 21 to the sheet-type conductive member 11 using the coated conductive wire connecting member constituted of the housing 31 and the pressure contact terminal 41 is described.

(53) First, as shown in FIG. 15, the sheet-type conductive member 11, the coated conductive wire 21, and the pressure contact terminal 41 joined to a carrier 46 are relatively positioned with respect to the housing 31. At this time, the sheet-type conductive member 11 is positioned on the +Y direction side of the housing 31 with the conductive pattern 13 formed on the surface of the sheet body 12 facing in the +Z direction. The coated conductive wire 21 is positioned on the +Z direction side of the housing 31, and the pressure contact terminal 41 is positioned on the Y direction side of the housing 31.

(54) As shown in FIG. 16, an end of the sheet-type conductive member 11 is inserted into the sheet-type conductive member insertion opening 32 of the housing 31 from the +Y direction toward the Y direction, and the tip end of the coated conductive wire 21 is inserted into the housing-side slit 33 of the housing 31 from the +Z direction toward the Z direction.

(55) Consequently, as shown in FIG. 17, the Y directional end of the sheet-type conductive member 11 is accommodated in the sheet-type conductive member accommodating portion 35 so as to abut on the step portion 37 of the housing 31, and the tip end of the coated conductive wire 21 penetrates through the housing 31 in the Z direction at the +Y directional end of the housing-side slit 33 of the housing 31.

(56) Since the housing-side slit 33 has the slit width W1 in the X direction that is equal to or slightly smaller than the diameter of the coated conductive wire 21, the tip end of the coated conductive wire 21 inserted in the housing-side slit 33 is held while penetrating through the housing 31.

(57) Next, as shown in FIG. 18, the pressure contact terminal 41 jointed to the carrier 46 is inserted into the pressure contact terminal insertion opening 34 of the housing 31 from the Y direction toward the +Y direction. At this time, as shown in FIG. 19, the two spring contacts 43 are elastically deformed as being inserted into the pressure contact terminal insertion opening 34 of the housing 31, and in this state, the pressure contact terminal 41 is thrust into the pressure contact terminal accommodating portion 36 of the housing 31.

(58) As shown in FIGS. 20 and 21, the pressure contact terminal 41 is inserted into the housing 31 and thrust into the pressure contact terminal accommodating portion 36 until the +Y directional end 42A of the flat portion 42 abuts on the abutment surface 36C at the +Y directional end of the pressure contact terminal accommodating portion 36 of the housing 31. When the +Y directional end 42A of the flat portion 42 abuts on the abutment surface 36C of the housing 31, the insertion of the pressure contact terminal 41 with respect to the housing 31 is completed. Thus, the pressure contact terminal 41 is accommodated in the pressure contact terminal accommodating portion 36 of the housing 31.

(59) Since the pressure contact terminal 41 is, with its slit opening end 45 being the front end, accommodated in the pressure contact terminal accommodating portion 36 through the pressure contact terminal insertion opening 34 of the housing 31, the tip end of the coated conductive wire 21 inserted and held by the housing-side slit 33 of the housing 31 is to be inserted in the terminal-side slit 44 from the slit opening end 45 of the pressure contact terminal 41. The terminal-side slit 44 has the slit width W2 in the X direction that is slightly smaller than the diameter of the conductor part 22 of the coated conductive wire 21; therefore, as shown in FIG. 22, the insulator part 23 covering the outer periphery of the conductor part 22 of the coated conductive wire 21 is cut and torn by the edge of the terminal-side slit 44 of the pressure contact terminal 41, so that the pressure contact terminal 41 comes into contact with the conductor part 22 of the coated conductive wire 21 to establish their electrical connection.

(60) As shown in FIG. 23, when the pressure contact terminal 41 is thrust into the pressure contact terminal accommodating portion 36 of the housing 31 until the +Y directional end 42A of the flat portion 42 abuts on the abutment surface 36C, the ends of the two elastically deformed spring contacts 43 pass over, in the +Y direction, the step portion 37 formed in the communicating part between the pressure contact terminal accommodating portion 36 and the sheet-type conductive member accommodating portion 35 of the housing 31 and reach the inside of the sheet-type conductive member accommodating portion 35. As a consequence, the sheet-type conductive member 11 accommodated in the sheet-type conductive member accommodating portion 35 is elastically pressed, in the Z direction, against the bottom 35A of the sheet-type conductive member accommodating portion 35 by the two spring contacts 43.

(61) Since the conductive pattern 13 is disposed on the surface of the sheet-type conductive member 11 on the +Z direction, the ends of the two spring contacts 43 come into contact with the conductive pattern 13 of the sheet-type conductive member 11, whereby the pressure contact terminal 41 is electrically connected to the conductive pattern 13 of the sheet-type conductive member 11.

(62) In other words, the conductor part 22 of the coated conductive wire 21 is electrically connected to the conductive pattern 13 of the sheet-type conductive member 11 via the pressure contact terminal 41 made of metal.

(63) Since the groove 38 is formed in the bottom 35A of the sheet-type conductive member accommodating portion 35 at the Y directional end thereof to be adjacent to the step portion 37, the sheet-type conductive member 11 is sandwiched between a shoulder of the groove 38 and the spring contacts 43 and held thereby, thus establishing the electrical connection between the spring contacts 43 and the conductive pattern 13 of the sheet-type conductive member 11.

(64) Even if the groove 38 is not present, since the spring contacts 43 elastically press the sheet-type conductive member 11 against the bottom 35A of the sheet-type conductive member accommodating portion 35, the spring contacts 43 and the conductive pattern 13 of the sheet-type conductive member 11 are electrically connected to each other; however, owing to such a configuration that the sheet-type conductive member 11 is sandwiched between the shoulder of the groove 38 and the spring contacts 43, the electrical connection can have improved reliability, and a holding force against the sheet-type conductive member 11 can be improved.

(65) After the pressure contact terminal 41 joined to the carrier 46 is thus inserted into the housing 31, the carrier 46 is disjoined from the pressure contact terminal 41 to thereby obtain the coated conductive wire connecting structure shown in FIGS. 1 to 3.

(66) For instance, a dividing groove is formed in advance between the carrier 46 and the pressure contact terminal 41 to separate them, and when, with respect to the pressure contact terminal 41 inserted in the housing 31, the carrier 46 is folded along the dividing groove, the carrier 46 can be disjoined from the pressure contact terminal 41.

(67) Thus, with the end of the sheet-type conductive member 11 being accommodated in the sheet-type conductive member accommodating portion 35 through the sheet-type conductive member insertion opening 32 of the housing 31, and with the end of the coated conductive wire 21 being inserted and held by the housing-side slit 33 of the housing 31, the pressure contact terminal 41 is inserted from the pressure contact terminal insertion opening 34 of the housing 31 to be accommodated in the pressure contact terminal accommodating portion 36; with this single action alone, the conductor part 22 of the coated conductive wire 21 can readily be electrically connected to the conductive pattern 13 of the sheet-type conductive member 11 via the pressure contact terminal 41.

(68) While, in Embodiment 1 above, the pressure contact terminal 41 has the two spring contacts 43 arranged on the opposite sides of the terminal-side slit 44, the invention is not limited thereto, and the pressure contact terminal 41 may have only a single spring contact 43. When the pressure contact terminal 41 has the two spring contacts 43 as in Embodiment 1, however, this ensures more reliable electrical connection of the pressure contact terminal 41 with the conductive pattern 13 of the sheet-type conductive member 11.

(69) While, in Embodiment 1 above, the housing 31 has the housing-side slit 33 as the coated conductive wire holding portion, the invention is not limited thereto, and the housing 31 may have a hole that receives the coated conductive wire 21 therein, as the coated conductive wire holding portion.

Embodiment 2

(70) In Embodiment 1, the housing 31 has the groove 38 recessed in the Z direction in the bottom 35A of the sheet-type conductive member accommodating portion 35 at the Y directional end thereof, and the sheet-type conductive member 11 is sandwiched between the shoulder of the groove 38 and the spring contacts 43 and held thereby; however, the invention is not limited thereto.

(71) The structure of a housing 51 used in a coated conductive wire connecting structure according to Embodiment 2 is shown in FIG. 24. The housing 51 is configured such that, in place of the groove 38, a projection 52 projecting in the +Z direction is formed on the bottom 35A of the sheet-type conductive member accommodating portion 35 at the Y directional end thereof in the housing 31 in Embodiment 1, and except that, the structure of the housing 51 is the same as that of the housing 31 in Embodiment 1.

(72) The housing 51 in Embodiment 2 is used along with the pressure contact terminal 41 in Embodiment 1.

(73) When the insertion of the pressure contact terminal 41 into the housing 51 is completed so that the pressure contact terminal 41 is accommodated in the pressure contact terminal accommodating portion 36 of the housing 51, as shown in FIG. 25, the ends of the elastically deformed spring contacts 43 are positioned beyond the step portion 37 of the housing 51 in the +Y direction, and the sheet-type conductive member 11 is sandwiched and held between the top of the projection 52 formed on the bottom 35A of the sheet-type conductive member accommodating portion 35 and the spring contacts 43, whereby the spring contacts 43 and the conductive pattern 13 of the sheet-type conductive member 11 are electrically connected to each other.

(74) The use of the housing 51 having the projection 52 as above also makes it possible to improve the reliability of the electrical connection and a holding force against the sheet-type conductive member 11, as with Embodiment 1.

Embodiment 3

(75) As shown in FIG. 26, the present invention can also be applied to a sheet-type conductive member 61 having plural conductive patterns 13 formed on the surface of the insulating sheet body 12.

(76) The Y directional ends of the conductive patterns 13 on the sheet-type conductive member 61 are separately accommodated in sheet-type conductive member accommodating portions 35 of housings 31 corresponding to the conductive patterns 13, coated conductive wires 21 are separately held by coated conductive wire holding portions of the housings 31, and in this state, as shown in FIG. 27, pressure contact terminals 41 are separately accommodated in pressure contact terminal accommodating portions 36 of the housings 31.

(77) The pressure contact terminals 41 are joined to a single carrier 46. By thrusting the carrier 46 in the +Y direction with respect to the housings 31, the pressure contact terminals 41 can readily be inserted into the housings 31 at once.

(78) As a result, the conductor parts 22 of the coated conductive wires 21 are electrically connected to the conductive patterns 13 of the sheet-type conductive member 61 via the pressure contact terminals 41, correspondingly.

(79) Thereafter, the carrier 46 is disjoined from the pressure contact terminals 41, thus obtaining the connecting structure between the coated conductive wires 21 and the sheet-type conductive members 61 as shown in FIG. 28.

(80) This procedure only involves thrusting the pressure contact terminals 41 in the +Y direction, and even when the arrangement pitch of the conductive patterns 13 is small in the sheet-type conductive member 61, the coated conductive wires 21 can readily be connected to the sheet-type conductive members 61 by inserting the pressure contact terminals 41 into the housings 31 at once.

(81) Even when the housings 31 are replaced by housings 51 described in Embodiment 2, it is possible to obtain the connecting structure between the coated conductive wires 21 and the sheet-type conductive members 61.
