【Example】

<Example 1> Hereinafter, Example 1 embodying the present invention will be described with reference to FIG.
It will be described with reference to FIG. The joint connector 1 of this embodiment is composed of a connector body 2 and a terminal connecting body 6. The connector body 2 is made of a non-conductive synthetic resin material, has a hood portion 3 which is open to the front side and into which a mating connector (not shown) is fitted, and a rear surface opposite to the opening side of the hood portion 3. It has a terminal protection part 4 protruding to the inside. In this terminal protection portion 4, a plurality of rectangular exposure holes 5 are formed so as to penetrate through both upper and lower surfaces. On the other hand, the terminal connection body 6 is formed by integrally molding a metal plate made of a conductive material by a press, and a plurality of elongated terminal pieces 7 are arranged in a row and adjacent terminal pieces 7, 7 are adjacent to each other at their base ends. Part 7
A and 7a are connected by the connecting portion 8. A circular retaining hole 9a is formed at a substantially central position in the length direction of each terminal piece 7, and retaining protrusions 9b protruding from both outer edges are formed.

The terminal connecting body 6 and the connector body 2 are integrated by insert molding. The terminal connecting body 6 has a retaining hole 9a and a retaining projection 9b.
By being arranged so as to be embedded inside the connector body 2, the connector body 2 is positioned at a predetermined position so that it cannot be pulled out. Each of the terminal pieces 7 of the terminal connecting body 6 has its tip portion projected into the inside of the hood portion 3 of the connector body 2, and these terminal pieces 7 serve as terminals of a mating connector (not shown) fitted into the hood portion 3. It is adapted to be fitted and electrically connected. In addition, the base end portion 7a of the terminal piece 7 and the connecting portion 8 between the terminal pieces 7 and 7
Is located in the terminal protection portion 4 of the connector body 2, and the lower surfaces of the terminal piece 7 and the connecting portion 8 are exposed flush with the lower surface of the terminal protection portion 4. Connecting part 8
Is smaller than the opening dimension of the exposed hole 5 of the terminal protection portion 4, and the connecting portion 8 is positioned so as to horizontally bridge the inner wall surfaces of the exposed hole 5.

The terminal connecting body 6 integrated with the connector body 2 as described above is divided into a plurality of joint terminals 10 by appropriately removing the connecting portion 8. Hereinafter, the step of dividing the terminal connection body 6 will be described. In this step, the press pin 11 for removing the connecting portion 8 and the receiving jig 12 for supporting the terminal piece 7 against the load received from the press pin 11 are used. The press pin 11 has each exposed hole 5
It is adapted to be vertically moved by a drive mechanism (not shown) in a state of protruding downward just above. Receiving jig 12
Contacts the lower surface of the terminal protection portion 4 and supports the terminal piece 7 exposed from this surface from below. A receiving groove 13 is formed on the upper surface of the receiving jig 12, and the receiving groove 13 is formed by the receiving jig 12 in the terminal piece 7.
It is adapted to be aligned with the exposed hole 5 in the state of supporting the.

When the terminal connecting body 6 is divided, the joint connector 1 of this embodiment is arranged at a predetermined position, the receiving jig 12 is set on the lower surface of the terminal protecting portion 4, and the press pin 11 is exposed through the exposing hole 5. Wait right above. From this state, the press pin 11 is moved downward.
A predetermined press pin 11 is selected according to the conduction pattern of the terminal of the mating connector, and only the selected press pin 11 moves down. The downwardly moved press pin 11 enters the inside of the exposure hole 5 and presses the connecting portion 8 from above, and the pressed connecting portion 8 is punched out and removed from between the terminal pieces 7 on both sides thereof. The removed connecting portion 8 becomes removed dust and is housed in the receiving groove 13 of the receiving jig 12 by being pushed down by the press pin 11. Thereafter, the press pin 11 moves upward while being removed from the exposure hole 5 and returns to the standby position, and the receiving jig 12 is detached from the terminal protection portion 4 while the removal waste 8 is accommodated in the receiving groove 13. .

When the connecting portion 8 is removed by the press pin 11, the terminal piece 7 is exposed flush with the lower surface of the terminal protection portion 4 and the terminal piece 7 is in direct contact with the receiving jig 12. Since it is supported by, press pin 1
When the pressing force of 1 acts on the connecting portion 8, the base portion 7a of the terminal piece 7 is deformed by being dragged by the connecting portion 8 so as to bend downward, or the connecting portion 8 is deformed due to the deformation of the terminal piece 7. There is no fear that 8 will not be punched and will remain deformed. Furthermore, since a part of the terminal protection part 4 is not sandwiched between the terminal piece 7 and the receiving jig 12, a part of the terminal protection part 4 is crushed and deformed by the terminal piece 7. That situation does not occur.

The scraps removed from the connecting portion 8 are pressed by the press pin 11.
Since it is pushed by the receiving jig 12 until it is accommodated in the receiving groove 13 of the receiving jig 12, the removed jig is surely discharged to the outside of the connector body 2 by the receiving jig 12. Even if the scraps removed from the connecting portion 8 are not properly stored in the receiving groove 13 of the receiving jig 12, since the connecting portion 8 is located flush with the lower opening surface of the exposure hole 5, The scrap does not remain inside the exposure hole 5 and falls and is reliably discharged to the outside of the exposure hole 5. In the state in which the connecting portion 8 is removed as described above, conduction cannot be established between the terminal pieces 7 on both sides of this removed portion, and this conduction is impossible (indicated by symbol S in FIG. 4).
The terminal connecting body 6 is divided into two joint terminals 10, 10 at the boundary. The arrangement pattern of the terminal pieces 7 of the plurality of joint terminals 10 configured by dividing the terminal connection body 6 in this manner matches the conduction pattern of the terminals of the mating connector, and the terminals of the joint connector 1 of the present embodiment. When the piece 7 and the terminal of the mating connector are connected, only the terminals of the mating connector that are connected to the same joint terminal 10 become conductive with each other.

In the joint connector 1 of this embodiment, when the connecting portion 8 to be removed is changed, the arrangement pattern of the terminal pieces 7 of the plurality of joint terminals 10 also changes. Therefore, by appropriately setting the connecting portion 8 to be removed according to the conduction pattern of the mating connector, it is possible to deal with various mating connectors having different conduction patterns. As described above, in the joint connector 1 of this embodiment, the terminal connecting body 6 is integrated with the connector body 2 and then the terminal connecting body 6 is divided to form a plurality of joint terminals 10. Therefore, the terminal connecting body 6 assembled to the connector body 2 is of a single type in which the arrangement pattern of the terminal pieces 7 is constant. Therefore, the terminal connecting body 6
It is possible to reduce the cost required for quality control and storage, and the cost required for equipment and management of the press mold for molding the terminal connecting body 6.

Further, in this embodiment, the connector body 2 and the terminal connecting body 6 are integrated by insert molding, and the connector body 2 is molded and the terminal connecting body 6 is assembled to the connector body 2. Attaching is done in a single step. Therefore, the connector body 2
As compared with the case where the terminal connecting body 6 is assembled after molding the single body, the number of manufacturing steps can be reduced by the assembling step of the terminal connecting body 6, so that the manufacturing efficiency can be improved and the terminal can be improved. Since the equipment for assembling the connecting body 6 is unnecessary, the manufacturing cost can be reduced. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG.
It will be described with reference to FIGS. Similarly to the joint connector 1 of the first embodiment, the joint connector 21 of the present embodiment also has the connector body 22 and the terminal connection body 26 integrated by insert molding. While the terminal pieces 7 are arranged in a line, in the present embodiment, the terminal pieces 27 of the terminal connection body 6 are arranged in two rows. The connector main body 22 has a hood portion 23 that opens to the front, and also has terminal protection portions 24 and 24 that project in two stages on the rear surface. Both terminal protection part 2
4, 4 and 24 have a pair of exposed holes 2 which are aligned with each other.
A plurality of pairs 5 and 25 are formed in parallel. On the other hand, the terminal connecting body 26 includes a plurality of terminal pieces 27 having the same shape as the terminal connecting body 6 of the first embodiment and the base end portion 2 thereof.
7a, 27a and a connecting portion 28 for connecting the two,
The terminal connection body 26 of the present embodiment is a terminal piece 27.
And a pair of connecting body constituent parts 26a, 26a having the same number and arrangement of the connecting parts 28. The pair of connecting body constituent parts 26a, 26a are integrated via a support part 26b. Such a terminal connection body 26
Are both connecting body constituent parts 26a, 26 in the support part 26b.
All terminal pieces 27 are folded back so that a is parallel.
Are formed so as to project in parallel with each other and the connecting portions 28 correspond to each other. The terminal connecting body 26 bent and formed in this manner is integrated with the connector body 22 by insert molding as described above. The connecting portion 28 of the terminal connecting portion 26 integrated with the connector main body 22 is positioned so as to be aligned with the exposure hole 25 formed in the terminal protecting portion 24 of the connector main body 22, and the connecting portion 28 and the terminal piece 27 are connected to each other. The base end portion 27a is a protective portion for both terminals 2.
It is exposed so as to be flush with the surfaces of 4, 4 facing each other.

In order to divide the terminal connecting body 26 having the above structure into a plurality of joint terminals, the press pin 3 is used.
1 and the receiving jig 32 are used. The press pins 31 are provided in pairs in a direction in which the tips of the press pins 31 abut each other in the horizontal direction, and as shown in FIG.
In a state in which the hood portion 23 is oriented upward, the terminal protection portions 24, 24 have the press pins 3 on both sides.
When arranged between the first and the third pins 31, each press pin 31 corresponds to the exposed hole 25. Also, the receiving jig 3
2 is fitted between the two terminal protection parts 24, 24 from below, abuts on the corresponding surfaces of the two terminal protection parts 24, 24, and is exposed at the corresponding surfaces.
7 is supported from the side. Receiving jig 32
Receiving grooves 33, 33 are formed on both side surfaces of the receiving groove 33. The receiving groove 33 is aligned with the exposure hole 25 when the receiving jig 32 supports the terminal piece 27.

When the terminal connecting body 26 is divided,
With the receiving jig 32 fitted between the terminal protection portions 24, 24, the predetermined press pin 31 selected corresponding to the conduction pattern of the mating connector (not shown) is moved forward. (In FIG. 9, a state in which both the two press pins 31 and 31 forming a pair are advanced is shown, but only one of the press pins 31 may be advanced.) The press pin 31 thus advanced enters the exposed hole 25 and punches out the connecting portion 28 thereof to remove it. The removed scraps of the removed connecting portion 28 are stored in the receiving groove 33 of the receiving jig 32. At the time of removing the connecting portion 28, there is no fear that the terminal piece 27 is deformed by the support of the receiving jig 32 or the connecting portion 28 remains without being removed due to the deformation.

In this embodiment, the connecting portion 28 is punched out horizontally and is accommodated in the receiving groove 33 on the side surface of the receiving jig 32. When removed from between 24, the scraps do not remain in the receiving groove 33 and fall surely. By thus removing the predetermined connecting portion 28, the terminal connecting body 26 is divided to form a plurality of joint terminals having a predetermined pattern.
Only the terminals of the mating connector (not shown) connected to the same joint terminal are electrically connected to each other.

Also in this embodiment, since the terminal connecting body 26 assembled to the connector body 22 is of a single type in which the arrangement pattern of the terminal pieces 27 is constant, the terminal connecting body 26 is the same as in the first embodiment. The cost required for quality control and storage, and the cost required for equipment and management of the press mold for molding the terminal connection body 26 can be kept low. In the present embodiment, one receiving jig 32 is commonly used when the connecting portions 28, 28 of both stages are removed. Therefore, the cost is lower than that when a dedicated receiving jig is provided in each stage. It is suppressed. In the present embodiment, the connecting portions 28, which are arranged in two stages,
Although the positions of 28 overlap between both stages, the press pins 31 provided exclusively for each stage are not provided on the same side but on opposite sides, so that the connecting portion 28 of any stage can be arbitrarily removed. Is possible. In this way, by making the positions of the connecting portions 28, 28 on both stages overlap, the dimension in the direction perpendicular to the parallel direction of the connecting portions 28, that is, the length direction of the terminal piece 27 is reduced,
It is being miniaturized.

<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIGS. Similar to the joint connector 21 of the second embodiment, the joint connector 41 of the present embodiment has terminal pieces 47 arranged vertically in two stages. Connector body 42 of this embodiment

In this terminal protection part 44, a plurality of pairs of exposure holes 45a, 45b are formed in parallel with each other so as to pass through the upper and lower surfaces of the terminal protection part 44 at intervals in the front-rear direction. The terminal connecting body 46 has a plurality of terminal pieces 47a and 47b, similar to the terminal connecting body 26 of the second embodiment.
And a pair of connecting body constituent parts 46a, 46b composed of the connecting parts 48a, 48b are integrated via a supporting part 46c, and are integrated with the connector main body 42 by insert molding in a state of being folded back at the supporting part 46c. Has been converted. The connection portion 48 of the terminal connection body 46 of this embodiment.
a and 48b are different from those of the terminal connecting body 26 of the second embodiment, and as shown in FIG.
The connecting portion 48a of 6a and the connecting portion 48b of the other connecting body forming portion 46b are formed at different positions in the length direction of the terminal pieces 47a, 47b. Therefore, as shown in FIG. 15, the connecting portions 48a and 48b of the terminal connecting body 46 that are folded back and integrated with the connector main body 42 have the upper connecting portion 48a exposed in the rear-side exposure hole 45a. At the same time, the lower connecting portion 48b is exposed in the front-side exposure hole 45b. In addition, the connecting portions 48a, 4
8b and the terminal pieces 47a, 47b are not flush with the upper surface or the lower surface of the terminal protection portion 44, and the base end portions of the terminal pieces 47a, 47b are the terminal protection portion 44.
It is completely buried inside.

In this embodiment, the press pin 5 is used to divide the terminal connecting body 46 into a plurality of joint terminals.
1a and 51b are used. Press pins 51a, 51b
Corresponds to the pair of front and rear exposed holes 45a and 45b.
One set is provided, and a plurality of sets are provided above the terminal protection portion 44 so as to be aligned with the exposed holes 45a and 45b of each pair. Among the press pins 51a and 51b of each set, the rear press pin 51a corresponding to the upper connecting portion 48a has a long standby distance from its tip to the upper surface of the terminal protection portion 44 and corresponds to the lower connecting portion 48b. The press pin 51b on the front side has a short standby distance to the terminal protection portion 44.

When the terminal connecting body 46 is divided,
