These first movable openings 16 and the first fixing holes 17 are used for moving the movable guide member 12 as described later.
(19) Further, the thickness 13c of the guide member main body 13 is, as for the movable guide member 12 located between the insertion punches 18, the same or substantially the same thickness so as to correspond to the distance 44 in the front and rear direction between the each rows of the press-fit terminals 35 which are arranged in the housing 34, and to which guide member main body 13 the press-fit terminals 35 of the each rows in the front and rear direction are attached when the press-fit terminals 35 are installed.
(20) The thickness of the guide member main body 13 of the movable guide member 12 placed at the inner most side (the front side) is unnecessary to be formed to have the same thickness corresponding to the distance 44 in the front and rear direction between the each rows of the press-fit terminals 35 but can be formed to have any thickness since the press-fit terminals 35 are placed on only one side of the movable guide member 12. In the connector 33 to which the press-fit terminals 35 formed in L-shape as shown in
(21) Then, the insertion punch 18 has a punch main body 19 which is a rectangular shape as shown in
(22) The width 20a of the gap of the punch grooves 20 is formed as a width into which the width 38a of the terminal main body 38 of the press-fit terminal 35 can be fitted. Further, shoulder receiving grooves 22 which are wider than the width 20a of the punch grooves 20 and into which the shoulders 40 of the press-fit terminals 35 are inserted are formed at the lower side of the punch grooves 20. The boundary portion of the upper part of the shoulder receiving grooves 22 to the punch grooves 20 constitutes pressing sections 23 for pressing the shoulders 40. The each shoulder receiving grooves 22 has tapers 22a at its lower end so as to smoothly receive the shoulder 40 and so as not to touch the press-fit section 39 formed at the lower side of the shoulder 40 of the press-fit terminal 35 (refer to
(23) The punch main body 19 is formed with a plurality of, e.g. three, circular second fixing holes 25 at an upper portion thereof, and a plurality of, e.g. two, second movable openings 24 of oval shape at a portion between the second fixing holes 25 and the punch grooves 20. These second fixing holes 25 and the second movable openings 24 are used for moving the movable guide members 12 as described later.
(24) The thickness of the punch main body 19 is formed as a thickness 19c which is the same or substantially the same thickness corresponding to the horizontal length perpendicular to the widthwise direction of the terminal main body 38 of the press-fit terminal 35 so as to receive the terminal main body 38 when the terminal main body 38 is fitted into the punch groove 20. The punch main body 19 has cut-out portions 19d on which portions elastic members 32 are disposed. The guide grooves 14 of the movable guide members 12 and the punch grooves 20 of the insertion punches 18 are formed so as to correspond each other at the state that the movable guide members 12 and the insertion punches 18 are assembled together and so that the each guide grooves 14 and the punch grooves 20 formed at the corresponded locations are communicated each other.
(25) The rear surface plate body 26 has a plate main body 27 which is a rectangular shape as shown in
(26) The first movable openings 16 of the movable guide member 12, second fixing holes 25 of the insertion punch 18, and the third movable openings 28 of the rear surface plate body 26 are, when the jig unit 11 is assembled, formed so as to correspond each other, and the first fixing holes 17 of the movable guide member 12, the second movable openings 24 of the insertion punch 18, and the third fixing holes 29 of the rear surface plate body 26 are formed so as to correspond each other.
(27) Next, the assembling process of the jig will be explained hereinafter. The jig unit 11 constituting the jig 10 is configured by, as shown in
(28) In the jig unit 11, the position of the lower ends 18a of the insertion punches 18 are located upper than the lower ends 12a of the movable guide members 12 and the lower end 26a of the rear surface plate body 26 with the gap G (refer to
(29) The jig unit 11 thus assembled is fixed by the fixing member 31 and is attached to the press-fitting device 30 as shown in
(30) In this way, the insertion punches 18 are fixed to the press-fitting device 30 while the movable guide members 12 and the rear surface plate body 26 are fixed together. Further, the movable guide members 12 and the rear surface plate body 26 can move upward and downward with respect to the insertion punches 18 fixed to the press-fitting device 30 since the bolts penetrating through the each first movable openings 16, third movable openings 28, and the second movable openings 24 which are formed in oval shape are moved. The movable guide members 12 and the rear surface plate body 26 are disposed on the press-fitting device 30 with the state of being pressed downward by means of the elastic member 32 which are provided on the above portion of the jig unit 11. The movable guide members 12 and the rear surface plate body 26 can move upward with respect to the press-fitting device 30 and the fixed-insertion punches 18 by the distance D corresponding to the distance of the insertion punches 18 being pressed downward.
(31) Then, the process for disposing press-fit terminals 35 to the jig 10 and installing to the substrate 42 will be explained with reference to
(32) In order to dispose the press-fit terminals 35 to jig 10, the press-fit terminals 35 are moved horizontally rearward and inserted from the front side face of the jig 10 as shown in
(33) The guide grooves 14 and the punch grooves 20 are formed and arranged so as to correspond with each other, thus they are penetrated throuthout the rear surface plate body 26 (refer to
(34) The insertion is implemented until the press-fit terminals 35 placed on the outermost rear side abut to the rear surface plate body 26. At this moment, since the press-fit terminals 35 placed on the outer most side of the connector 33 abut to the rear surface plate body 26, the one portion of the terminal main bodies 38 of each press-fit terminals 35 including the shoulder 40, press-fit section 39, and the distal portion 36 are placed at the position to which the insertion punches 18 are placed. The movable guide member 12 is placed between the front low and the rear low of the each press-fit terminals 35 which are arranged in array.
(35) Afterward, the jig 10 is moved in the vertical direction to set the press-fit terminals 35 into the jig. This insertion is implemented by firstly moving the jig downward in the vertical direction and thus the insertion punches 18 moves downward, the shoulders 40 of the press-fit terminals 35 are fitted into the shoulder receiving grooves 22 of the insertion punches 18 as shown in
(36) The movable guide members 12 are moved downward beyond the shoulders 40 and the press-fit sections 39 of the press-fit terminals 35 by moving the jig 10 downward in the vertical direction (refer to
(37) Thereafter, the press-fit terminals 35 are installed to the substrate 42. This installation process is implemented by, firstly shown in
(38) Afterward, by moving the jig 10 downward as shown
(39) Therefore, according to the jig 10 of the embodiment, buckling can be restricted when the press-fit terminals 35 are press-fitted to the substrate 42 since the press-fit terminals 35 are guided by the punch grooves 20 and the shoulder receiving grooves 22 of the insertion punches 18 at its right and left direction i.e. widthwise direction and also guided by the first comb-teeth 15 of the movable guide members 12 at its front and rear direction. Especially, the press-fit terminals 35 are guided by the movable guide members 12 when the press-fit sections 39 are press-fitted, thus the buckling can be further restricted.
(40) The rear surface plate body 26 guides the shoulders 40 and the all the entire rear surface of the press-fit sections 39 when the rear surface plate body 26 relatively moves upward with respect to the insertion punches 18, the buckling can be restricted also by the rear surface plate body 26. At this moment, since the movable guide members 12 and the rear surface plate body 26 relatively move upward with respect to the insertion punches 18, the elastic member 32 disposed on the above portion of the jig 10 is compressed and the elastic force is accumulated. As explained above, installation of the press-fit terminals 35 to the substrate 42 is completed.
(41) As the jig 10 moves upward, the movable guide members 12 and the rear surface plate body 26 which have already relatively moved upward are pressed downward and placed back to the original position by the elastic force of the elastic member 32 disposed on the jig 10. Therefore, the installation can be repeatedly conducted by the press-fitting device 30 which is provided with the jig 10, thus the installation process can be enhanced.
(42) In the above embodiment, the jig unit constituting the jig is explained as being configured by assembling two movable guide members, two insertion punches, and one rear surface plate body. However, the invention is not limited to this, and the number of the movable guide members and the insertion punches can be changed in accordance with the number of the low of the press-fit terminals disposed on the connector to be installed. It can be applied to and corresponded to the many connectors by assembling the movable guide members, insertion punches, and the rear surface plated body. Therefore, the manufacturing cost for the jig can be reduced since there is no need for manufacturing a jig for a specific connector.
(43) In the embodiment, the case in which the jig is attached to the press-fitting device and used is explained. However, the invention is not limited to this, the jig of the present invention can be used in any devices for installing the press-fit terminals, in general.
