The return spring 110 biases the sliding member 102 toward the back plate 60, that is, in a direction away from the holder 51 and the other end portion 64 b of the lever member 64.
[0122]
With the above-described configuration, the release mechanism 58 moves the wire 101 away from the housing setting jig 1 when the lever 104 is rotated along the arrow P1 in FIG.
[0123]
Then, the sliding member 102 rotates the lever member 64 in a direction to release the locking of the locking claw 73 with respect to the pressure contact housing 40 against the urging force of the return spring 110. When the lever 104 is rotated along the arrow P2 opposite to the arrow P1, the sliding member 102 is displaced in the direction approaching the back plate 60 by the urging force of the return spring 110, and the locking claw 73 is pressed against the press housing. The lever member 64 is rotated by the urging force of the coil spring 65 in the direction of being locked to 40.
[0124]
When the joint connector 5 is formed by stacking the pressure setting housing 40 on the housing setting jig 1 having the above-described configuration, first, an operator pulls the operation cord 95 and the locking ball 92 is moved to the locking recess 80. The holder 51 is positioned by locking. Then, the operation lever 82 of the cam mechanism 54 is operated to position the guide members 52 and 53 at the positioning positions described above. At this time, the recess 90 of the restricting member 55 is engaged with the outer edge of each holder 51 to position each holder 51.
[0125]
The press-contact housings 40 having the identification portions 46 corresponding to the erroneous attachment preventing portions 68 are respectively attached to the holders 51. At this time, the insertion direction of the press-contact housing 40 is guided by the guide recess 79. When the press-contact housing 40 corresponding to the product number is mounted on the holder 51 in a desired direction, the locking claw 73 of the lever member 64 is locked to the press-contact housing 40. Furthermore, a cover housing 49 is mounted on the further upper side of the press-contact housing 40 located at the uppermost position when the joint connector 5 is configured.
[0126]
Then, the operation lever 82 of the cam mechanism 54 is rotated along the arrow R1 in FIG. 4 to rotate the guide members 52 and 53 in a direction in which the interval between the guide portions 74 is increased. The guide members 52 and 53 are positioned at the positioning release position described above.
[0127]
Thereafter, the holder 51 is pressed in the direction in which the press-contact housing 40 and the cover housing 49 attached thereto are brought close to each other, and the locking portion 44 and the lock receiving portion 45 are locked to each other. 49 are fixed to each other.
[0128]
The lever 104 of the release mechanism 58 is rotated along the arrow P2 in FIG. 10, and the lever member 64 is rotated in the direction in which the engagement of the engagement claw 73 with the press contact housing 40 is released. The pressure contact housing 40 and the cover housing 49 in which the lever member 64 is unlocked are removed from the holder 51 to obtain the joint connector 5 described above.
[0129]
Thereafter, the lever 104 is rotated along the arrow P 1 to displace the lever member 64 to a position where the press contact housing 40 can be locked, and the operating string 95 is pulled to engage the locking ball 92 with the locking recess 80. Stop. Then, the cam mechanism 54 is operated to displace the guide members 52 and 53 to the positioning positions described above. The next joint connector 5 is assembled in accordance with the steps described above.
[0130]
When the joint connector 5 is configured without attaching the press-contact housing 40 and the cover housing 49 to all the holders 51 among the holders 51 described above, the dummy housing 49a shown in FIGS. You may make it do.
[0131]
Further, when the joint connector 5 is configured without attaching the press contact housing 40 and the cover housing 49 to all of the holders 51 described above, the press contact housings 40 are sequentially arranged from the holder 51 located on the right side in FIG. The cover housing 49 is attached. That is, the above-described dummy housing 49a is located on the left side in FIG.
[0132]
In the above-described embodiment, the operation cord 95 is attached to the holder 51 located at the left end in FIG. 2, so that when the holders 51 are pressed toward each other, the holder 51 in FIG. It is desirable to move toward the right side.
[0133]
According to the present embodiment, the press contact housing 40 is mounted on the plurality of holders 51 that can be contacted and separated from each other. For this reason, after the pressure contact housing 40 is mounted on the holder 51, the pressure contact housings 40 can be stacked by bringing the pressure contact housing 40 for each holder 51 closer. Therefore, it is possible to suppress the labor and the like required when the pressure contact housings 40 are stacked to form the joint connector 5.
[0134]
The erroneous attachment preventing portion 68 prevents the press contact housing 40 having the wrong product number from being attached to each holder 51. For this reason, the press-contact housing 40 can be reliably held according to the stacking order. Therefore, it is possible to suppress the time and labor required for stacking the pressure contact housings 40 and to prevent the yield when the joint connector 5 is assembled from deteriorating.
[0135]
The misdirection prevention unit 69 prevents the pressure contact housing 40 from being attached to the holder 51 in a state where the first surfaces 47a or the second surfaces 47b face each other. For this reason, the press-contact housing 40 can be reliably held in the holder 51 in a state where the first surface 47a and the second surface 47b face each other. Therefore, the joint connector 5 can be reliably assembled by stacking the pressure contact housings 40 by bringing the holder 51 closer.
[0136]
In the positioning positions of the guide members 52 and 53, the guide recess 79 guides the press-contact housing 40 to each holder 51. For this reason, while being able to mount | wear the press contact housing 40 to the holder 51 reliably, the effort concerning the mounting | wearing can be suppressed. Furthermore, since the guide members 52 and 53 allow the press contact housings 40 attached to the holder 51 to approach each other at the positioning release position, the press contact housings 40 can be reliably stacked.
[0137]
When the guide members 52 and 53 are positioned at the positioning positions, the restricting member 55 restricts the holder 51 from moving in the contacting / separating direction. As described above, the restriction member 55 positions the holder 51 when the press-contact housing 40 is mounted on the holder 51.
[0138]
Therefore, the guide recesses 79 of the guide members 52 and 53 can be reliably guided to the holders 51, and the press-contact housing 40 can be mounted. It is possible to suppress the time and effort required to mount the press-contact housing 40 on the holder 51, and to more reliably suppress the time and labor required when stacking the press-contact housing 40.
[0139]
The band-shaped rubber 56 urges the holder 51 so that the intervals between them are equal. For this reason, the plurality of holders 51 are positioned in a state where the intervals between the adjacent holders 51 are substantially equal.
[0140]
When the guide members 52 and 53 guide the press-contact housing 40 to the holder 51, the locking ball 92 is locked to the locking recess 80 of one holder 51. For this reason, the holder 51 is reliably positioned by the locking portion 59. The pressure contact housing 40 can be easily and reliably mounted by the holder 51. In addition, due to the urging force of the belt-like rubber 56, the intervals between the press-contact housings 40 are more surely closer to the equal intervals.
[0141]
The release mechanism 58 can release the locking of the lever member 64 with respect to the press contact housing 40 when the joint connector 5 is assembled. For this reason, after the joint connector 5 is assembled, the locking of the lever member 64 can be quickly released and removed. Accordingly, it is possible to more reliably suppress the labor required when assembling the joint connector 5, that is, the labor required when laminating the press-contact housings 40.
[0142]
Since the slider 77 that supports the plurality of holders 51 so as to be able to contact and separate from each other is longer than the thickness of the holder 51, the holders 51 can be brought into and out of contact with each other without rattling. Further, since the slider 79 supporting the holder 51 adjacent to the hole 111b enters, the holder 51 can be brought close to the hole 51b.
[0143]
Furthermore, since the thickness of the holder 51 is thinner than the thickness of the press-contact housing 40, the press-contact housing 40 can be reliably stacked by bringing the holders 51 close to each other.
[0144]
【The invention's effect】
As described above, according to the first aspect of the present invention, an insulator is attached to a plurality of holders that can be contacted and separated from each other. For this reason, after attaching an insulator to a holder, an insulator can be laminated | stacked by approaching the said insulator for every holder. Since the insulators can be stacked by bringing the holders equipped with the insulators close to each other, it is possible to suppress labor and the like required for stacking the insulators.
[0145]
Erroneous attachment preventing means Holder is wrong insulator is prevented from being mounted. For this reason, it can hold | maintain reliably according to the order which laminates | stacks an insulator. Therefore, since the insulator can be attached to the holder without error, it is possible to suppress the trouble and the like required when laminating the insulator.
[0146]
According to the second aspect of the present invention, the misdirection preventing means prevents the insulator from being attached to the holder in a state where the first surfaces or the second surfaces are opposed to each other. For this reason, an insulator can be reliably hold | maintained in the state in which a 1st surface and a 2nd surface mutually oppose. Therefore, the joint connector can be reliably assembled by bringing the holder closer. It is possible to more reliably suppress labor and the like required when laminating the insulators.
[0152]
According to the third aspect of the present invention, the lock release means releases the lock of the lever member with respect to the insulator when the joint connector is assembled. For this reason, after the joint connector is assembled, the locking of the lever member can be quickly released and removed. Therefore, it is possible to more reliably suppress the effort required when assembling the joint connector, that is, the effort required when laminating the insulators.
[0153]
According to the fourth aspect of the present invention, since the slider that supports the plurality of holders so as to be able to come in contact with and separate from each other is longer than the thickness of the holder, it is possible to suppress backlash when the holders are brought into contact with and separated from each other. Moreover, since the slider which supports the adjacent holder invades in the escape portion, the holder can be brought closer more reliably.
