JP 2002-184505 A

  In the joint connector, in addition to the short-circuit terminal and the insulating housing, it is necessary to provide a dedicated retainer for preventing the terminal from coming off. Therefore, there is a problem that the number of parts increases and the structure becomes complicated.

  In view of such circumstances, an object of the present invention is to provide a joint connector capable of reducing the number of parts and short-circuiting terminals with a simple structure.

  As means for solving the above-mentioned problems, the present invention provides a plurality of terminals respectively connected to terminals of a plurality of electric wires, an insulating housing having a terminal accommodating chamber into which the plurality of terminals are inserted from the rear, and A short circuit made of metal that has a plurality of fitting portions that can be respectively fitted to the plurality of terminals accommodated in the terminal accommodating chamber, and that short-circuits the plurality of terminals fitted to the fitting portions so as to be conductive. A first position where the fitting portion and the terminal inserted into the terminal accommodating chamber from behind can be fitted, and the short-circuit member is separated from the first position. The insulating housing is held so as to be movable integrally with the terminal between the second position, and the insulating housing has moved to the second position and a locking portion for locking the short-circuit member. Short circuit member mating part and mating There is provided a joint connector comprising: a retaining portion for retaining the terminals in a certain position so as to restrict the terminals from coming out of the terminal housing chamber backward (claim). 1).

  According to such a configuration, by positioning the short-circuit member at the first position, each terminal accommodated in the terminal accommodating chamber can be fitted to the fitting portion, and the fitting is performed. By moving the short-circuit member to the second position in the combined state, it is possible to restrict each terminal from coming out of the terminal accommodating chamber. That is, when the short-circuit member is moved to the second position, each terminal fitted to the short-circuit member is moved to a position locked by the retaining portion, and the retaining portion is removed from the terminal accommodating chamber. Prevents each terminal from coming out backwards.

  Thus, in the above configuration, the terminal is prevented from coming off by the retaining portion provided in the insulating housing by integrally moving the short-circuit member and the plurality of terminals instead of the conventional retainer. As a result, it is not necessary to provide a separate retainer for restricting the removal of the terminals, and the number of parts can be reduced.

  In the present invention, it is preferable that the second position is a position separated from the first position in a direction perpendicular to the insertion direction of the terminal (claim 2).

  In this way, the terminal is removed by moving the short-circuit member and each terminal in a direction perpendicular to the terminal insertion direction, so that a tensile force parallel to the terminal insertion direction is applied to each terminal. However, it is possible to more reliably regulate the movement of each terminal and prevent the terminal from coming off.

  Further, in the present invention, the plurality of terminals have contact portions that protrude from the respective electric wires to which the terminals are connected in a direction perpendicular to the insertion direction of the terminals, and the retaining portion includes the terminal accommodating portion. The terminal inserted from the rear into the chamber is allowed to be fitted with the short-circuit member at the first position, while the contact of the terminal at the position to be fitted with the short-circuit member at the second position is It is preferable to have a shape that abuts against the contact portion from behind (Claim 3).

  According to this structure, the terminal can be easily inserted while avoiding the retaining portion, while the retaining portion is brought into contact with the abutting portion of each terminal from the rear, so that the terminals can be disconnected. Can be regulated more effectively.

  Also, in the present invention, the short-circuit member is integrally formed with a plurality of terminal locking portions that lock the terminals that are respectively fitted to the fitting portions at the fitting positions. The locking portion has a shape that can be elastically deformed between a locking position where the terminal can be locked and a locking release position that retracts from the locking position and releases the locked state of the terminal. (Claim 4).

  According to this structure, since the plurality of terminals can be locked to the short-circuit member at the fitting position where the plurality of terminals are fitted to the fitting portion, the short-circuit member is the first position. It is possible to prevent the fitting state from being released when moving to the second position. Further, according to this structure, since the terminal may be inserted along the terminal locking portion while the terminal locking portion is displaced to the unlocking position, the terminal can be easily inserted. Become.

  In particular, since the terminal locking portion is formed integrally with the short-circuit member and is made of metal, the frictional resistance with the metal terminal is reduced compared to the case where the terminal locking portion is formed of synthetic resin or the like. Can be small. Therefore, when the terminals are inserted along the terminal locking portions as described above, these terminals can be inserted more easily. On the other hand, since the terminal locking portion is made of metal, the rigidity of the terminal locking portion can be increased. Therefore, when each terminal is locked to the terminal locking portion, the engagement force with each terminal is increased. Can be increased.

  Moreover, in this invention, it is preferable that the said insulation housing has a temporary latching | locking part which latches the said short circuit member in said 1st position (Claim 5).

  In this way, since the short-circuit member is locked at the first position, the plurality of terminals can be easily inserted into the terminal accommodating chamber, and the plurality of terminals and the fitting portion Can be more stably performed.

  In the present invention, the insulating housing has a housing portion that can house the short-circuit member so as to be movable between the first position and the second position, and is housed in the housing portion. It is preferable to have an operation portion for operating the short-circuit member from the outside of the insulating housing so that the short-circuit member moves from the first position to the second position.

  In this way, the short-circuit member can be moved while avoiding exposure of the short-circuit member to the outside. Here, the operation portion may be, for example, a through hole into which a predetermined jig for pressing and moving the short-circuit member can be inserted, or formed in the insulating housing, and the short-circuit member It may be a flexible piece that can be moved by pressing.

  As described above, according to the present invention, it is possible to provide a joint connector capable of reducing the number of parts with a simple configuration.

  An embodiment of a joint connector according to the present invention will be described with reference to the drawings.

  The curved portion 23 has a shape such that a tip curved downward from the front end portion of the connection portion 21 extends rearward, and is substantially U-shaped. The plurality of fitting portions 22 protrude further rearward from the end of the portion extending rearward of the bending portion 23 and face the connection portion 21 in the vertical direction. The fitting portions 22 can be electrically connected to each other via the curved portion 23 and the connecting portion 21.

  The fitting portion 22 is a male type that is inserted into the main body 42 a of the electrical connection portion 42 of the terminal 40 and fits with each terminal 40. As shown in FIG. 4 etc., each fitting part 22 is electrically connected with the terminal 40 by contacting with the contact spring piece 42b provided in the main body 42a of the electrical connection part 42 of the corresponding terminal 40. . Here, since each fitting part 22 can conduct | electrically_connect through the said bending part 23 as mentioned above, the some terminal 40 is fitted by each fitting part 22, and each fitting part 22 is each. The terminals 40 are short-circuited by being electrically connected.

  The terminal locking portion 24 is for locking the terminal 40 that is fitted to each fitting portion 22 at the fitting position. These terminal locking portions 24 are provided at positions facing the fitting portions 22 in the vertical direction. Specifically, a through hole 21a extending in the arrangement direction of the fitting portion 22 is formed at the center of the connection portion 21, and the terminal locking portion 24 is directed forward from the rear peripheral edge of the through hole 21a. Each extending. That is, each terminal locking portion 24 has a shape in which the rear end is connected to the connection portion 21 and the front end is elastically displaceable (deflable) in the vertical direction. These terminal locking portions 24 are respectively formed with terminal locking holes 24a penetrating vertically, and the terminal locking holes 24a and terminal locked protrusions 44 described later provided in the respective terminals 40 are engaged. By joining, each terminal latching | locking part 24 latches each terminal 40 in the said fitting position.

  The terminal locking portion 24 is elastically deformed in the vertical direction as described above, so that the terminal 40 can be locked, and the terminal locking portion 24 is retracted from the locking position to lock the terminal. It is displaced between the unlocking position for releasing the state. Therefore, when inserting each terminal 40 into the terminal accommodating chamber 12, it is relatively easy to insert the terminal locking portion 24 at the front end of each terminal 40 while displacing the terminal locking portion 24 to the locking release position. it can.

  In the bus bar side wall portion 26, a bus bar temporary locking hole 26a and a bus bar main locking hole 26b penetrating the bus bar side wall portion 26 are formed at positions spaced apart in the vertical direction. The bus bar temporary locking holes 26 a and the bus bar main locking holes 26 b have shapes that can be engaged with bus bar locking protrusions 16 described later provided in the insulating housing 10. Then, the bus bar temporary locking hole 26a and the bus bar locking projection 16 are engaged, whereby the bus bar 20 is locked to the insulating housing 10 at a first position described later. Further, the bus bar main locking hole 26b and the bus bar locking projection 16 engage with each other, whereby the bus bar 20 is locked to the insulating housing 10 at a second position described later.

  The insulating housing 10 accommodates the bus bar 20 and the plurality of terminals 40 so as to be movable in the vertical direction. The insulating housing 10 is formed with a terminal accommodating chamber 12 for accommodating the plurality of terminals 40 and a bus bar accommodating chamber (accommodating portion) 17 for accommodating the bus bar 20.

  The terminal accommodating chamber 12 includes a plurality of first terminal insertion portions 12a that open rearward, and a second terminal insertion portion 12b that is formed in front of the first terminal insertion portion 12a.

  The first terminal insertion portion 12a is provided for each terminal 40, functions as an insertion port for each terminal 40, and is provided behind the electrical connection portion 42 of each terminal 40 after insertion of each terminal 40. It functions as a part for accommodating the barrel part 40a and the like. The first terminal insertion portion 12a is a through-hole penetrating from the rear end surface of the insulating housing 10 toward the second terminal insertion portion 12b, and has a hole diameter through which the electric connection portion 42 of the terminal 40 can be inserted. is doing.

  The second terminal insertion portion 12b is a portion that houses the electrical connection portion 42 of each terminal 40 inserted into the first terminal insertion portion 12a. The second terminal insertion portion 12b is formed between a bottom portion 13 and a cover 14 which are connected to an opening surface where the first terminal insertion portion 12a opens forward. The bottom portion 13 constitutes a part of the bottom surface of the insulating housing 10 and has a substantially rectangular parallelepiped shape. On the other hand, the cover 14 constitutes a part of the upper surface and the side surface of the insulating housing 10 and has a shape covering the bottom portion 13. The second terminal insertion portion 12 b includes a plurality of terminal insertion grooves 13 b formed in the bottom portion 13 and a portion surrounded by the bottom portion 13 and the cover 14.

  The terminal insertion groove 13b has a shape that is recessed below the bottom surface of the first terminal insertion portion 12a, and there is a step at the boundary with the first terminal insertion portion 12a. This step forms a retaining portion 15 that locks the terminal 40 in a retaining state. That is, the electrical connection portion 42 of the terminal 40 inserted into the terminal insertion groove 13b moves downward as the bus bar 20 moves, so that the rear end surface (contact portion) 42d of the electrical connection portion 42 is The step comes into contact with the rear, and the contact prevents the terminal 40 from moving in the terminal insertion direction.

  The bus bar accommodating chamber 17 is formed by a portion surrounded by the bottom portion 13 and the cover 14, and the bus bar 20 is disposed between the first position and the second position described later in the bus bar accommodating chamber 17. It is housed movably. Further, on both side surfaces of the bottom portion 13, bus bar locking protrusions 16 that can be engaged with the bus bar temporary locking holes 26 a and the bus bar main locking holes 26 b are provided so as to protrude outward. The insulating housing 10 can temporarily lock the bus bar 20 accommodated in the bus bar accommodating chamber 17 to the first position by the engagement between the bus bar locking protrusion 16 and the bus bar temporary locking hole 26a. On the other hand, the bus bar 20 can be fully locked at the second position by the engagement between the bus bar locking protrusion 16 and the bus bar main locking hole 26b.

  The first position is a position where each terminal 40 inserted into the terminal accommodating chamber 12 can be fitted into the fitting portion 22. The second position is a position below the first position, where each terminal 40 fitted to the bus bar 20 can be locked in the retaining state by the retaining portion 15. is there. That is, in the state where the bus bar 20 is in the second position, the retaining portion 15 comes into contact with the rear end surface 42d of the main body 42a of the electrical connection portion 42 of each terminal 40 from the rear, and each terminal 40 moves rearward. It becomes impossible.

  An operation hole (operation part) 18 is formed in the upper surface of the insulating housing 10. The operation hole 18 is opened so as to communicate with the bus bar housing chamber 17 and has a size capable of inserting a predetermined jig. Then, by pressing the bus bar 20 accommodated in the bus bar accommodating chamber 17 with the jig, the bus bar 20 is moved from the first position to the second position by an operation from the outside of the insulating housing 10. It can be made to.

  Next, a method of inserting the terminals 40 into the insulating housing 10 to short-circuit each terminal 40 and prevent it from coming off will be described.

  First, the bus bar locking projection 16 provided in the insulating housing 10 is engaged with the bus bar temporary locking hole 26a formed in the bus bar 20, and the bus bar 20 is temporarily locked in the first position. . In this state, the plurality of terminals 40 to which the terminals of the plurality of electric wires 30 are respectively connected are inserted from the rear of the terminal accommodating chamber 12. Specifically, the terminal locking portion 24 provided on the bus bar 20 at the front end portion of each terminal 40 is inserted while being displaced upward. At this time, the fitting portion 22 of the bus bar 20 is inserted into the electric connection portion 42 of each terminal 40, and each electric connection portion 42 and the fitting portion 22 are fitted. Then, the terminals 40 are short-circuited by being electrically connected to each other via the bending portion 23 connected to the fitting portion 22. Further, the terminal locking holes 24a provided in the terminal locking portions 24 and the terminal locked protrusions 44 provided in the terminals 40 are engaged, and the terminals 40 are engaged with the bus bar 20 in the fitted state. Primary locking.

  Next, a jig such as a screwdriver is inserted into the operation hole 18 of the insulating housing 10, and the bus bar 20 is pressed and moved downward by the jig. Specifically, the bus bar 20 is moved to the second position where the bus bar locking hole 26b provided in the bus bar 20 and the bus bar locking protrusion 16 engage with each other, and the bus bar locking hole 26b. The bus bar 20 is finally locked at the second position by the engagement between the bus bar 20 and the bus bar locking protrusion 16. At this time, since each terminal 40 is primarily locked by the terminal locked protrusion 44 as described above, the bus bar 20 is integrated with the terminal 40 while the fitting portion 22 and the terminal 40 are fitted. Move to. When the bus bar 20 moves to the second position, each terminal 40 moves to a position where the retaining portion 15 can come into contact with the rear end surface 42d of the electrical connecting portion 42 from the rear.

  In this way, when the retaining portion 15 comes into contact with the rear end surface 42d of the electrical connecting portion 42 from the rear side, the terminal 40 is secondary-locked so that it cannot move rearward even when a backward pulling force is applied. Is done.

  As described above, according to the present joint connector 1, the bus bar 20 is held by the insulating housing 10 so as to move between the first position and the second position. Detachment for locking each terminal 40 in a position to be fitted with the fitting part 22 of the bus bar 20 in the second position so that these terminals 40 are prevented from coming out of the terminal accommodating chamber 12 backward. Since it has the stop part 15, while holding the bus-bar 20 in a 1st position, while being able to fit each terminal 40 and the fitting part 22, the bus-bar 20 is maintained in the fitting state. By moving to the second position, it is possible to restrict each terminal 40 from coming out of the terminal accommodating chamber 12. That is, according to the present joint connector 1, it is possible to regulate the disconnection of each terminal 40 without separately providing a retainer, and thus it is possible to reduce the number of parts.

  Further, as described above, if the second position is a position separated from the first position in the direction perpendicular to the terminal insertion direction, the bus bar 20 is moved in the direction perpendicular to the terminal insertion direction. As a result, the disconnection of each terminal 40 is regulated, so that it is possible to more reliably prevent the disconnection of each terminal 40 when a tensile force is applied to the electric wire connected to each terminal 40. Become.

  Further, as described above, the retaining portion 15 is allowed to be fitted with the bus bar 20 at the first position while the terminal 40 is fitted with the bus bar 20 at the second position. The terminal 40 can be inserted into the terminal accommodating chamber 12 while avoiding the retaining portion 15 if it is shaped so as to come into contact with the rear end surface 42d of the electrical connection portion 42 of the terminal 40 from behind. On the other hand, the disconnection of the terminal 40 can be more effectively regulated.

  Further, a terminal locking part 24 for locking the terminal 40 at the fitting position with the fitting part 22 is formed integrally with the bus bar 20, and the terminal locking part 24 can be locked with the terminal 40. If the terminal lock portion 24 is elastically deformed between the lock position and the lock release position that retreats from the lock position and releases the lock state of the terminal 40, the terminal lock portion 24 allows the terminal 40 to be Since the terminal 40 can be inserted while the terminal locking part 24 is displaced to the locking release position while being able to be moved while maintaining the fitted state with the fitting part 22, insertion of each terminal 40 is possible. Can be easily performed.

  In particular, since the terminal locking portion 24 is formed integrally with the metal bus bar 20, for example, compared with a lance formed on the insulating housing 10 made of synthetic resin, for example, the friction resistance with the metal terminal 40 is increased. Is low. And this low resistance makes insertion of the terminal 40 easier. Further, the metal terminal locking portion 24 has high rigidity, and this high rigidity enhances the engagement force between the terminal locking portion 24 and the terminal 40, and as a result, more reliable locking of the terminal 40.

  As described above, in addition to the final locking at the second position, the bus bar 20 is formed with the bus bar temporary locking hole 26a, and the bus bar locking protrusion 16 of the insulating housing 10 and the bus bar temporary locking hole 26a are engaged. Thus, if the bus bar 20 is temporarily locked at the first position, the bus bar 20 can be held at the first position in a stable state. 12 and the fitting of each terminal 40 and the fitting portion 22 can be performed more easily.

  Further, if the bus bar accommodating chamber 17 is formed in the insulating housing 10 and the bus bar 20 is accommodated in the insulating housing 10 and the operation hole 18 capable of operating the bus bar 20 is formed in the insulating housing 10, the bus bar 20 is moved to the outside. The bus bar 20 can be moved while avoiding the exposure of.

  Here, in the said embodiment, although the case where the said bus bar 20 moved to the direction perpendicular | vertical to the insertion direction of the terminal 40 was shown, the electrical connection part 42 of the terminal 40, the retaining part 15, and the bus bar 20 are moved. The bus bar 20 may be configured to move in an oblique direction or the like.

  Further, the contact portion with the retaining portion 15 is not limited to the rear end surface 42d of the electrical connecting portion 42, and may be any portion that can be in contact with the retaining portion 15 in parallel with the terminal insertion direction.

  Moreover, although the said terminal accommodating chamber 12 was shown about the case where it formed with the 1st terminal insertion part 12a which accommodates the barrel part 40a of the terminal 40, and the 2nd terminal insertion part 12b which accommodates the electrical connection part 42, this 2nd was shown. You may make it accommodate the whole terminal 40 including the said barrel part 40a in the terminal insertion part 12b. In this case, the retaining portion 15 and the rear end portion of the barrel portion 40a may be in contact with each other.

  Further, the terminal locking portion 24 of the bus bar 20 can be omitted. However, by primarily locking the terminal 40 to the bus bar 20 side by the terminal locking portion 24, the fitting state between the fitting portion 22 of the bus bar 20 and the terminal 40 can be more reliably maintained. The terminal 40 can be moved integrally with the bus bar 20 as it is.

  Further, the bus bar temporary locking hole 26a can be omitted. Further, even when the bus bar 20 is locked to the insulating housing 10 at the first position and the second position, the two engaged members locked to the insulating housing 10 on the bus bar 20 side as described above. Instead of providing the stop portions (the bus bar temporary locking hole 26a and the bus bar main locking hole 26b), two locking portions for locking the bus bar 20 may be provided on the insulating housing 10 side.

  Further, instead of the operation hole 18, a pressing portion that can be elastically deformed may be provided in the insulating housing 10, and the bus bar 20 may be moved by operating the pressing portion.
