  As described above, the connector module terminal connected to the terminal carrier is disconnected from the terminal carrier by cutting the connecting portion prior to insertion and storage in the terminal storage portion of the terminal housing. This separation from the terminal carrier is usually performed by cutting the connecting portion using a carrier cut punch, and when the connecting portion is cut by the carrier cut punch, a part thereof remains as a cutting allowance. Inevitable.

  In the past, this has caused a problem. That is, there is a problem that the remaining connecting portion protrudes from the tip of the bottom wall of the receiving portion, that is, the tip of the connector module terminal, which makes it difficult to manage the dimensions of the connector module terminal.

  Moreover, the problem by the cutting | disconnection burr | flash which has generate | occur | produced at the front-end | tip of a residual connection part was also invited. In other words, the remaining connecting portion protrudes from the outer surface of the receiving portion bottom wall because it is bent by receiving a cutting pressure at the time of cutting by the carrier cut punch. For this reason, the bottom wall of the housing portion of the terminal housing made of synthetic resin is damaged by cutting off the cutting edge of the remaining connecting portion when inserting the connector module terminal into the terminal housing portion, depending on the extent of the damage. This is a problem in that it may cause a contact failure in the connector module terminal.

  The present invention has been made in the background of the circumstances as described above, and for the connector module terminal having a terminal carrier that is to be finally disconnected, the remaining connecting portion that is generated when the terminal carrier is cut and separated. The problem is to eliminate the problems caused. More specifically, a first object is to prevent the remaining connecting portion from protruding from the end face of the connector module terminal when the terminal carrier is cut or separated. Another object of the present invention is to prevent the bottom wall of the storage portion of the terminal housing from being damaged by the cutting burr generated at the tip of the remaining connecting portion.

In order to solve the first problem and the second problem , the present invention includes a connector module terminal and a terminal housing for housing the connector module terminal, and the connector module terminal has a receiving portion bottom wall. The receiving part is formed and connected to the terminal carrier through a connecting part integrally extending from the front end of the receiving part bottom wall, and the terminal housing is in a state where the connector module terminal is inserted and stored. It has a terminal storage portion formed with a storage portion bottom wall facing the receiving portion bottom wall, and the connecting portion prior to inserting and storing the connector module terminal into the terminal storage portion from the distal end side of the conductor receiving portion. The connector module end is disconnected from the terminal carrier by cutting the connector module. Is formed such that the extended end of the connecting portion extending from the receiving portion bottom wall bites into the leading end edge of the receiving portion bottom wall, and the conductor receiving portion includes the receiving portion top wall and the receiving portion top wall. The receiving portion side wall is formed in a rectangular tube shape, and the position of the leading edge of the receiving portion top wall is biased rearward with respect to the position of the leading edge of the receiving portion bottom wall. A groove having a width wider than the width of the connecting portion of the connector module terminal and narrower than the width of the bottom wall of the receiving portion of the connector module terminal is formed on the wall .

  In this way, by extending the extending end of the connecting portion from the bottom wall of the receiving portion from the leading edge of the receiving portion bottom wall, the remaining connecting portion generated when the terminal carrier is cut or separated is removed from the connector module terminal. It is possible to avoid a state of protruding from the end face. Therefore, the dimension management of the connector module terminals can be performed more easily.

Meanwhile, the conductor receiving portions of the pin connector module as described above in addition to the receptacle bottom wall, the case formed rectangular tube having a receiving portion ceiling wall and receiving portion side wall, the carrier cut punch When the connecting portion is cut by the interference, the receiving portion ceiling wall interferes, which restricts the cutting position of the connecting portion and causes the remaining connecting portion to protrude from the end face of the connector module terminal.

In the present invention these reasons, the connector module terminal as described above, it is assumed to be biased to the rear relative to the position of the leading edge of the receiving pocket portion bottom wall position of the leading edge of the receiving portion top wall.

  By doing in this way, it can avoid that a receiving part top wall becomes an interference element at the time of the cutting | disconnection of a connection part by a carrier cut punch, and the protrusion from the terminal end surface for connector modules of a remaining connection part can be prevented.

In the connector module of the present invention , the housing bottom wall can be prevented from being damaged by the cutting burr of the remaining connecting portion when the connector module terminal is inserted by the groove formed on the housing bottom wall. That is, the groove portion has a width wider than that of the connecting portion and narrower than that of the receiving portion bottom wall, and thus functions to prevent the tip of the remaining connecting portion from coming into contact with the storage portion bottom wall. As a result, it is possible to avoid damage to the bottom wall of the storage portion due to the cutting burr of the remaining connecting portion when the connector module terminal is inserted.

  According to the present invention as described above, with respect to the connector module terminal having the terminal carrier to be finally disconnected, it is possible to solve the problem caused by the remaining connecting portion that occurs when the terminal carrier is cut or separated. Become. More specifically, it becomes possible to avoid the remaining connecting portion from protruding from the end face of the connector module terminal when the terminal carrier is cut or separated, and by the cutting burr generated at the tip of the remaining connecting portion. It is possible to prevent a situation in which the bottom wall of the housing portion of the terminal housing is damaged.

  Hereinafter, modes for carrying out the present invention will be described. FIG. 1 shows an overall external configuration of a connector module according to an embodiment. The connector module 1 in FIG. 1 is configured by inserting and storing metal connector module terminals 4 in each terminal storage portion 2 of a synthetic resin terminal housing 3 in which a plurality of terminal storage portions 2 are formed. In the connector module 1, the connector module terminals 4 are inserted and accommodated in the number corresponding to the number of the terminal accommodating portions 2, but only one connector module terminal 4 is shown in the figure.

  As shown in FIGS. 2 and 3, the connector module terminal 4 is provided with a conductor receiving portion 5 for receiving an electrical conductor (not shown) such as an electric wire and is a connection partner of the connector module 1. A contact portion 6 is provided for electrical connection with an external terminal or the like.

  The conductor receiving part 5 is also a part that is inserted and stored in the terminal storing part 2, and has a receiving part bottom wall 11, a receiving part top wall 12, and left and right receiving part side walls 13, 13. By being surrounded, it is formed in a rectangular tube shape. The receiving part bottom wall 11 and the receiving part top wall 12 in the conductor receiving part 5 are in a relationship in which the position of the leading edge 14 of the receiving part top wall 12 is biased backward with respect to the position of the leading edge 15 of the receiving part bottom wall 11. Is formed.

  The receiving portion top wall 12 is provided with a tension spring portion 16 formed by cutting and raising a part thereof in an inclined state. The tension spring portion 16 is fixed to the terminal accommodating portion 2 by being stretched with respect to the terminal accommodating portion 2 in a state where the conductor accepting portion 5 is inserted and accommodated in the terminal accommodating portion 2 as described later. It works to do.

  A connecting portion 17 is integrally extended from the leading end of the receiving portion bottom wall 11 (state shown in FIG. 2). The connecting portion 17 is configured such that an extending end extending from the receiving portion bottom wall 11 bites in from the leading edge 15 of the receiving portion bottom wall 11. More specifically, the connecting portion 17 is formed with respect to the distal end edge 15 so as to form U-shaped biting portions 18 on both sides between the extending side end portion and the distal end portion of the receiving portion bottom wall 11. I'm trying to bite in. The connecting portion 17 is integrated with the terminal carrier 19. Therefore, the connector module terminal 4 is integrally connected to the terminal carrier 19 via the connecting portion 17.

  The connection between the connector module terminal 4 and the terminal carrier 19 by the connecting portion 17 is disconnected prior to insertion / storage of the connector module terminal 4 into the terminal storage portion 2 (FIG. 3 is disconnected from the terminal carrier 19). Shows later state). The connector module terminal 4 is disconnected from the terminal carrier 19 by cutting the connecting portion 17 with a carrier cut punch 21 as shown in FIG. The cutting of the connecting portion 17 by the carrier cut punch 21 is performed by setting a position where a necessary cutting margin is provided from the extending side end of the connecting portion 17 as a cutting position (a portion indicated by a dotted line in the enlarged view portion in FIG. 2). The Accordingly, the connecting portion 17 remains as the remaining connecting portion 22 by the cutting allowance (see FIG. 3). And this remaining connection part 22 bends by receiving the cutting pressure by the carrier cut punch 21, and it will be in the state which protrudes from the outer surface of the receiving part bottom wall 11 by this.

  When such a remaining connecting portion 22 protrudes from the tip of the receiving portion bottom wall 11, that is, the tip of the connector module terminal 4, the size management of the connector module terminal 4 becomes complicated. Therefore, it is necessary to prevent the remaining connecting portion 22 from protruding, but the above-described biting structure of the connecting portion 17 functions for this. That is, the extension end in the extension from the receiving portion bottom wall 11 is bitten from the tip edge 15 of the receiving portion bottom wall 11, so that the cutting position can be maintained even if a necessary cutting margin is provided from the extension side end. Therefore, the remaining connecting portion 22 can be prevented from protruding from the tip of the connector module terminal 4 without protruding from the tip of the connector terminal 4.

  Further, the above-described biasing structure of the receiving portion top wall 12 with respect to the receiving portion bottom wall 11 also helps prevent the remaining connecting portion 22 from protruding. When the conductor receiving part 5 is formed in a rectangular tube shape having the receiving part bottom wall 11, the receiving part top wall 12, and the receiving part side wall 13 as described above, it is received when the connecting part 17 is cut by the carrier cut punch 21. If the ceiling wall 12 interferes, this restricts the cutting position of the connecting portion 17 and causes the remaining connecting portion 17 to protrude from the end face of the connector module terminal 4. Since the position of the leading edge 14 of the wall 12 is biased backward with respect to the position of the leading edge 15 of the receiving part bottom wall 11, the receiving part top wall 12 interferes when the connecting part 17 is cut by the carrier cut punch 21. It can avoid becoming an element, and it can prevent that the remaining connection part 17 protrudes from the end surface of the connector module terminal 4 by this.

  FIG. 5 is a partial view of the detailed structure of the terminal storage portion 2 seen from the front, and FIG. 6 is an external view of the connector module terminal 4 inserted and stored in the terminal storage portion 2 of the terminal housing 3. Is partially shown. As can be seen in these drawings, the terminal storage portion 2 has a storage portion bottom wall 23 and a storage portion top wall 24. The connector module terminal 4 is inserted into and stored in the terminal storage portion 2 from the distal end side of the conductor receiving portion 5, that is, the side where the remaining connecting portion 17 is present, and is received in the inserted and stored state. The bottom wall 11 faces the storage section bottom wall 23, and the receiving section top wall 12 faces the storage section top wall 24.

  In such insertion and storage of the connector module terminal 4 into the terminal storage portion 2, the remaining connecting portion 22 protruding from the outer surface of the receiving portion bottom wall 11 as described above has the storage portion bottom wall. When it comes into contact with 23, there is a possibility that the storage portion bottom wall 23 may be damaged by cutting burr generated at the remaining connecting portion 22. In order to cope with the problem caused by the cutting burr of the remaining connecting portion 22, the groove portion 25 is provided in the storage portion bottom wall 23.

  The groove portion 25 is formed so that the storage portion bottom wall 23 can support the receiving portion bottom wall 11 while avoiding the remaining connecting portion 22. More specifically, the groove 25 is wider than the width of the connecting portion 17 and narrower than the width of the receiving portion bottom wall 11, and the depth is deeper than the protruding length of the remaining connecting portion 22 from the receiving portion bottom wall 11. And both sides are formed as stepped portions 26.

  By providing such a groove portion 25, the receiving portion bottom wall 11 is supported only by the step portion 26, and the remaining connecting portion 22 is floated from the receiving portion bottom wall 11 by the groove portion 25 and the conductor receiving portion 5 is accommodated in the terminal. It will be inserted into part 2. That is, the groove portion 25 functions to prevent the tip of the remaining connecting portion 22 from coming into contact with the storage portion bottom wall 23. With this function, the remaining connecting portion 22 is inserted when the conductor receiving portion 5 is inserted into the terminal storage portion 2. This prevents the cutting burr from damaging the bottom wall 23 of the storage unit.

  As mentioned above, although the form for implementing this invention was demonstrated, this is only a typical example, This invention can be implemented with a various form in the range which does not deviate from the meaning.
