By the way, when the circuit terminal is inserted into the housing in which the short terminal is installed, since the circuit terminal is inserted into the terminal accommodating chamber in which the contact portion of the short terminal protrudes, there is a contact load between the short terminal and the circuit terminal. Slide in the given state. When the male housing and the female housing are fitted, the short-circuit releasing bar provided in the mating connector intervenes between the short Rizuko and the circuit terminal, so that the short-circuit is released. On the other hand, when the male housing and the female housing are detached and the mating is released, the short-circuit releasing bar comes out between the short terminal and the circuit terminal, so that the two electrodes are short-circuited again. At this time, both terminals are short-circuited again without sliding.
However, when the short-circuit release bar is interposed between the circuit terminal and the short terminal for a relatively long time, the conventional connector with a front holder is short-circuited again without sliding when the short-circuit release bar is pulled out. Therefore, when an oxide film is formed at the contact point between the circuit terminal and the short terminal, the contact resistance may increase due to the oxide film when the circuit terminal and the short terminal come into contact with each other. This increase in contact resistance is particularly significant for dissimilar metal plating contacts.

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a connector capable of improving contact reliability by preventing an increase in contact resistance due to an oxide film at the time of a short circuit by a short terminal. .

The above object of the present invention is achieved by the following configuration.
(1) A female housing to which a female terminal is attached, a male housing to which a male terminal connected to the female terminal is attached, and a pair of male or female terminals that are attached to the female housing or the male housing can be short-circuited. A connector for releasing a short circuit between the pair of male or female terminals and the short terminal when the connector is fitted, in a male housing or a female housing to which the short terminal is mounted. By projecting and fitting the connector, the pair of male terminals or female terminals and the short-circuit releasing wall having an insulation property inserted between the short terminal, the connector fitting operation and the connector fitting releasing operation A short terminal pressing projection for pressing and releasing the short terminal, and the short terminal pressing projection is pressed and released by the short terminal. A contact portion that is deformed by contact with the pair of male terminals or female terminals slides on the outer surface of the male terminals or female terminals.

  According to this connector, when the connector is mated, the short terminal is pushed and elastically deformed by the short terminal push projection, and after the contact is slid, it is moved to the short-circuit release wall to be in an insulating position. The contact is slid from the insulating position to the male terminal or the female terminal by the restoring force. Thereby, even when a short-circuit occurs again when the connector is detached, sliding between the male terminal or the female terminal and the short terminal can be caused to break the oxide film.

(2) The connector according to (1), wherein when the contact portion slides on the outer surface of the male terminal or the female terminal by releasing the pressing of the short terminal pushing protrusion, the short terminal is increased in a direction in which a contact force is increased. The connector is characterized in that a ride-on protrusion for pressing is provided on a male housing or a female housing to which the short terminal is attached.

  According to this connector, when the connector is fitted, the short terminal is pushed and elastically deformed by the short terminal pushing projection, and after the contact is slid, it is moved to the short-circuit releasing wall to be an insulating position. At this time, the short terminal descends from the riding protrusion and the amount of elastic deformation becomes small. When the connector is released, the contact is slid from the insulation position to the male terminal or the female terminal by the elastic restoring force of the short terminal. At this time, the short terminal rides on the riding protrusion again, the amount of elastic deformation increases, and the contact force during sliding increases. This ensures destruction of the oxide film even when re-shorting when the connector is detached.

  According to the connector of the present invention, sliding with a contact load occurs between the short terminal and the circuit terminal, so that the oxide film on the surface of both terminals is mechanically damaged, and particularly contact reliability against dissimilar metal plating contact. Improves.

FIG. 5 is an exploded perspective view, FIG. 5 is a front view of a female housing, and FIG. 6 is a perspective view of a short terminal.
The connector 11 has a female housing 15 to which the female terminal 13 is attached and a male housing 19 to which a male terminal 17 connected to the female terminal 13 is attached. The male housing 19 and the female housing 15 can be fitted to each other. Both housings are made of a synthetic resin material. In addition, both housings have the fitting surface side as the front.

First, the male housing 19 into which the female housing 15 can be fitted will be described.
A male housing 19 shown in FIG. 2 includes a male housing main body 21 and a rectangular tube-shaped hood 23 surrounding the male housing main body 21, and the male housing main body 21 accommodates a plurality of male terminals 17. A chamber 25 (see FIG. 1) is formed. The male terminal accommodating chamber 25 accommodates the male terminals 17, and each male terminal 17 is prevented from being detached by a male terminal lance 27.

  The tab 29 of the male terminal 17 protrudes forward from the male terminal accommodating chamber 25 and faces the hood portion 23 so that it can be connected to the counterpart female terminal 13. A ridge 31 is formed on the inner wall of the hood portion 23 along the longitudinal direction, and a guide groove 33 (see FIG. 4) provided in the female housing 15 is engaged with the ridge 31 so that the female housing 15 The fitting is guided.

  A lock projection 35 is provided vertically at the center of the bottom surface of the top plate of the hood portion 23, and the lock projection 35 is a lock engagement portion 39 of a lock arm 37 (see FIG. 4) formed in a cantilever shape on the upper portion of the female housing 15. Engage with. When the male housing 19 and the female housing 15 are fitted, the lock projection 35 presses down the lock arm 37, and the lock latching portion 39 of the lock arm 37 which is elastically restored upon completion of the fitting is engaged with the lock projection 35 to be detached. Is regulated. The engagement lock is released by pressing the release operation portion 41 (see FIG. 4) which is the free end of the lock arm 37, and the lock projection 35 and the lock engaging portion 39 are separated to release the engagement lock. The

  A tab through hole 45 through which the tab 29 passes is formed in the front wall portion 43 of the male housing located in the back of the hood portion 23. In the present embodiment, a plurality of tab through holes 45 are arranged in the upper and lower stages on the front wall portion 43 of the male housing. A pair of left and right short terminal push projections 47 project between the upper and lower tab through holes 45. The short terminal pushing protrusion 47 is formed in a prismatic shape, and is inserted into a short terminal accommodating chamber 49 (see FIG. 4) described later of the female housing 15 when the connector is fitted. The short terminal pushing protrusion 47 presses and releases the short terminal 51 in the female housing 15 by the connector fitting operation and the connector fitting releasing operation.

  Next, the female housing 15 will be described. In the female housing 15, the female housing front wall portion 53 is inserted into the hood portion 23 of the male housing 19. A plurality of tab receiving holes 55 corresponding to the tabs 29 are formed in the upper and lower two stages on the front wall portion 53 of the female housing. A female terminal housing chamber 59 (see FIG. 1) for housing the female terminal 13 is formed in the female housing main body 57, and the female terminal housing chamber 59 communicates with the tab receiving hole 55. The female terminal accommodating chamber 59 accommodates the female terminal 13 and is prevented from being detached by a female terminal lance 61 (see FIG. 1).

  A short terminal accommodating chamber 49 is opened between the upper and lower tab receiving holes 55 in the front wall portion 53 of the female housing. The short terminal accommodating chamber 49 is formed below the upper female terminal accommodating chamber 59 and accommodates the short terminal 51. The short terminal push projection 47 protruding from the male housing front wall 43 described above enters the short terminal accommodating chamber 49. The short terminal pushing protrusion 47 that has entered the short terminal accommodating chamber 49 pushes the short terminal 51 accommodated at the tip.

  As shown in FIG. 6, the short terminal 51 includes a contact portion 63, a vertical spring portion 65, a fitting direction spring portion 67, a contact upright piece 69, and a locking projection 71. The contact portion 63 is a contact portion with the pair of female terminals 13. The vertical spring portion 65 has a spring property that biases the female terminal 13. The fitting direction spring portion 67 has a spring property that elastically deforms the short terminal 51 in accordance with the fitting / release of the fitting, and this spring property also contributes to the urging force of the female terminal 13. The contact upright piece 69 serves as a contact seat for the short terminal push projection 47. The locking protrusion 71 locks the short terminal 51 to the locking claw 50 (see FIG. 5) of the short terminal accommodating chamber 49 and restricts the detachment.

  A short-circuit releasing wall 75 shown in FIG. 1 is provided between the female terminal accommodating chamber 59 and the short terminal accommodating chamber 49. The short-circuit releasing wall 75 is formed so as to protrude along the entry path of the tab 29, and the contact portion 63 of the short terminal 51 that is pushed back by the short terminal pressing protrusion 47 rides on the connector fitting. The contact portion 63 riding on the short-circuit releasing wall 75 is isolated from the female terminal 13 and insulated. The short terminal 51 is deformed when the short terminal pressing projection 47 is pressed and released, and the contact portion 63 that contacts the pair of female terminals 13 slides on the outer surface of the female terminal 13. That is, the short terminals 51 enable the pair of female terminals 13 attached to the female housing 15 to be short-circuited, and operate so as to cancel the short-circuit by the short terminals 51 of the pair of female terminals 13 when the connector is fitted.

Next, the operation of the connector 11 configured as described above will be described.
7 is a cross-sectional view of the connector 11 shown in FIG. 1 in the middle of fitting, and FIG. 8 is a cross-sectional view of the connector 11 shown in FIG.
The short terminal 51 is locked in the short terminal accommodating chamber 49 of the female housing 15 by the locking projection 71, and the female terminal 13 is accommodated in the female terminal accommodating chamber 59. At this time, the contact portion 63 of the short terminal 51 receives a contact load by the action of the vertical spring portion 65 and comes into contact with the pair of female terminals 13 so that the two adjacent poles are short-circuited. A male terminal 17 is accommodated in the male terminal accommodating chamber 25 of the male housing 19.

  When the female housing 15 and the male housing 19 are fitted, the male terminal 17 first enters the female terminal 13 and the circuit is conducted. At this time, the adjacent circuits are still short-circuited as shown in FIG. Thereafter, the short terminal pushing protrusion 47 provided on the male housing 19 comes into contact with the contact rising piece 69 of the short terminal 51, and the fitting direction spring portion 67 of the short terminal 51 is contracted as the fitting progresses. The part 63 moves backward.

  A short-circuit releasing wall 75 is provided between the female terminal accommodating chamber 59 and the short terminal accommodating chamber of the female housing 15, and the contact portion 63 of the short terminal 51 that has moved rearward is formed on the short-circuit releasing wall 75 as shown in FIG. Since it enters below, the short circuit between the adjacent female terminals is released, and at the same time, the connector 11 is completely fitted.

  On the other hand, when the fitting of the female housing 15 and the male housing 19 is released, the fitting direction spring portion 67 of the short terminal 51 is contracted by the short terminal pushing protrusion 47 of the male housing 19. The contact portion 63 moves forward and contacts the female terminal 13 at a location beyond the short-circuit release wall 75 as shown in FIG. As a result, the short terminal 51 comes into contact with the pair of female terminals 13 again and the adjacent circuits are short-circuited. Here, the contact direction 63 of the short terminal 51 and the female terminal 13 are slid by the fitting direction spring portion 67 in a state where a contact load is applied by the action of the vertical spring portion 65 of the short terminal 51. Arise. By this sliding, the oxide film formed on the surfaces of the short terminal 51 and the female terminal 13 is destroyed, and the two terminals are reliably in contact with each other.

  As described above, in the connector 11, when the connector is fitted, the short terminal 51 is pushed by the short terminal pushing projection 47 to be elastically deformed, and after the contact portion 63 is slid, it is moved to the short-circuit releasing wall 75 to be an insulating position. At the time of release, the contact portion 63 is slid to the female terminal 13 from the insulating position by the elastic restoring force of the short terminal 51. Thereby, even when a short-circuit occurs again when the connector is detached, sliding can be caused between the female terminal 13 and the short terminal 51, and the oxide film can be broken.

  In addition, according to the connector 11 according to the present embodiment, the function of the short-circuit releasing wall 75 that is usually formed thin on the male housing 19 opposite to the short terminal 51 is formed on the inner wall of the short terminal accommodating chamber 49. In addition, the thin-projection-shaped short-circuit releasing wall 75 is unnecessary, and there is also a secondary effect that the possibility of deformation due to “dozing” and molding failure is reduced.

  In the prior arts of Patent Documents 1 and 2, the short terminal is structured to be assembled to a slider (movable body) (not shown). When the short terminal and the slider are assembled with an interference fit, there is no backlash between the short terminal and the slider. However, since the slider moves relative to the male housing, a backlash is required between the male housing and the slider. In this case, there is a backlash between the short terminal and the male housing, and the required dimensional accuracy with respect to the male housing and the slider becomes high in order to stabilize the contact between the short terminal and the male terminal. In this configuration, when the short terminal 51 and the female housing 15 are assembled with an interference fit, there is no backlash between the short terminal 51 and the female housing, and the short circuit of the fitting detection member is released between the short terminal 51 and the female terminal 13. Therefore, the required dimensional accuracy with respect to the female housing 15 and the fitting detection member is lowered. As a result, the required dimensional accuracy of each component can be relaxed, and there is also an effect that manufacture is easier than in the prior art.

Next, a second embodiment in which the short terminal 51 is provided in the male housing 19 opposite to the above configuration will be described.
FIG. 9 is a cross-sectional view illustrating an enlarged main portion of the connector 11A according to the second embodiment in which the male housing 19A is provided with the short terminal 51, and FIG. 10 is an exploded view of the male housing 19A shown in FIG. 11 is a front view of the male housing 19A shown in FIG. 10, FIG. 12 is an exploded perspective view of the female housing 15A shown in FIG. 9, and FIG. 13 is a front view of the female housing 15A shown in FIG. 14 is a sectional view of the connector 11A shown in FIG. 9 in the middle of fitting, and FIG. 15 is a sectional view of the connector 11A shown in FIG. In the following embodiments, the same parts as those shown in FIGS. 1 to 8 are denoted by the same reference numerals, and redundant description is omitted.
In the connector 11A according to the present embodiment, the short terminal 51 is provided in the male housing 19A. For this reason, the male housing 19A is provided with a short terminal accommodating chamber 49 and a short-circuit releasing wall 75 below the male terminal accommodating chamber 25.

  On the other hand, a short terminal push projection 47 projects from the female housing front wall 53 of the female housing 15A, and the short terminal push projection 47 can enter the short terminal accommodating chamber 49 of the male housing 19A.

  In this connector 11A, as shown in FIG. 14, the short terminal 51 is locked in the short terminal accommodating chamber 49 of the male housing 19A by the locking projection 71 (see FIG. 6), and the female terminal accommodating chamber 59 is in the female terminal. 13 is accommodated. At this time, the contact portion 63 of the short terminal 51 is applied with a contact load by the action of the vertical spring portion 65 to come into contact with the male terminal 17, and the two adjacent poles are short-circuited.

  When the female housing 15A and the male housing 19A are fitted, the male terminal 17 first enters the female terminal 13 and the circuit is conducted. As shown in FIG. 14, the adjacent circuits are still short-circuited at this point. Thereafter, the short terminal pushing protrusion 47 provided on the female housing 15A comes into contact with the contact rising piece 69 of the short terminal 51, and the fitting direction spring portion 67 of the short terminal 51 is contracted as the fitting progresses. The part 63 moves backward.

  As shown in FIG. 9, the contact portion 63 of the short terminal 51 moved rearward enters the lower part of the short-circuit releasing wall 75, so that the short circuit between the adjacent male terminals is released, and at the same time, the connector 11A is completely fitted.

  On the other hand, when the fitting of the female housing 15A and the male housing 19A is released, the fitting direction spring portion 67 of the short terminal 51 is contracted by the short terminal pushing protrusion 47 of the female housing 15A. The contact portion 63 moves forward and contacts the male terminal 17 at a location beyond the short-circuit releasing wall 75 as shown in FIG. As a result, the short terminal 51 again contacts the pair of male terminals 17 and the adjacent circuits are short-circuited. Here, the contact direction spring portion 67 slides between the contact portion 63 of the short terminal 51 and the male terminal 17 in a state where a contact load is applied by the vertical spring portion 65 of the short terminal 51. By this sliding, the oxide film formed on the surfaces of the short terminal 51 and the male terminal 17 is destroyed, and the terminals are reliably in contact with each other.

Next, a third embodiment in which the riding protrusion 77 is provided will be described.
FIG. 16 is a cross-sectional view illustrating an enlarged portion of a main part of the connector 11B according to the third embodiment provided with the riding protrusion 77, and FIG. 17 is a perspective view of the female housing 15B shown in FIG. FIG. 18 is a front view of the female housing 15B shown in FIG.
The connector 11 and the connector 11A described above are preferably provided with a protrusion 77 on the male housing 11, 11A or the female housing 15, 15A to which the short terminal 51 is mounted. In the present embodiment, a case where the short terminal 51 is provided in the female housing 15B will be described as an example. Therefore, the riding protrusion 77 is formed on the female housing 15B.

  As shown in FIGS. 17 and 18, the climbing projections 77 are provided in pairs on the front side of the bottom surface of each short terminal accommodating chamber 49. The protrusion rear part 79 of the ride-on protrusion 77 becomes an inclined surface on which the short terminal 51 that has returned to elasticity and moved forward can easily ride. When the connector fitting is released, when the contact portion 63 slides on the outer surface of the female terminal 13 due to the release of the short terminal pushing projection 47, the riding protrusion 77 rises, and as a result, contact The short terminal 51 is pressed by the reaction force in the direction of increasing the force.

Next, the operation of the connector 11B configured as described above will be described.
19 is a cross-sectional view of the connector 11B shown in FIG. 16 in the middle of fitting, and FIG. 20 is a cross-sectional view of the connector 11B shown in FIG.
The short terminal 51 is locked in the short terminal accommodating chamber 49 of the female housing 15B by a locking projection 71 (see FIG. 6), and the female terminal 13 is accommodated in the female terminal accommodating chamber 59. At this time, the short terminal 51 rides on the ride-up protrusion 77, is applied with a strong contact load by the action of the vertical spring portion 65, contacts the female terminal 13, and the adjacent two poles are short-circuited. The male terminal 17 is accommodated in the male terminal accommodating chamber 25 of the male housing 19B.

  When the female housing 15B and the male housing 19B are fitted, as shown in FIG. 19, first, the male terminal 17 enters the female terminal 13 and the circuit is conducted. At this time, the adjacent circuits are short-circuited. Thereafter, the short terminal pushing projection 47 provided on the male housing 19B comes into contact with the contact rising piece 69 of the short terminal 51, and the fitting direction spring portion 67 of the short terminal 51 is contracted as the fitting progresses. The part 63 moves backward.

  A short-circuit releasing wall 75 is provided between the female terminal accommodating chamber 59 and the short terminal accommodating chamber 49 of the female housing 15B, and the contact part 63 of the short terminal 51 moved rearward is short-circuit releasing wall as shown in FIG. Since it enters below 75, the short circuit between adjacent female terminals is released, and at the same time, the connector 11B is completely fitted. At this time, since the short terminal 51 descends from the riding protrusion 77, the deformation is alleviated, and the reaction force from the short-circuit releasing wall 75 prevents over-compression and plastic deformation.

  On the other hand, when the fitting of the male housing 19B and the female housing 15B is released, the fitting direction spring portion 67 of the short terminal 51 is contracted by the short terminal pushing protrusion 47 of the male housing 19B. The contact part 63 moves forward and contacts the female terminal 13 at a place beyond the short-circuit releasing wall 75. As a result, the short terminal 51 comes into contact with the pair of female terminals 13 again and the adjacent circuits are short-circuited. Here, as shown in FIG. 20, the short terminal 51 rides on the riding protrusion 77 again, and is strong between the contact portion 63 of the short terminal 51 and the female terminal 13 by the action of the vertical spring portion 65 of the short terminal 51. In a state where a contact load is applied, sliding by the fitting direction spring portion 67 occurs. By this sliding, the oxide film formed on the surfaces of the short terminal 51 and the female terminal 13 is destroyed, and the two terminals are reliably in contact with each other.

  Thus, in this connector 11B, when the connector is fitted, the short terminal 51 is pushed by the short terminal pushing projection 47 to be elastically deformed, and after the contact is slid, it is moved to the short-circuit releasing wall 75 to be an insulating position. At this time, the short terminal 51 descends from the riding protrusion 77 and the elastic deformation amount becomes small. When the connector is released, the contact is slid from the insulating position to the female terminal 13 by the elastic restoring force of the short terminal 51. At this time, the short terminal 51 rides on the riding protrusion 77 again, and the amount of elastic deformation increases, and the contact force during sliding increases. This ensures destruction of the oxide film even when re-shorting when the connector is detached.

  Therefore, according to the connectors 11, 11A, and 11B according to the above-described embodiments, sliding with a contact load occurs between the short terminal 51 and the circuit terminal, so that the oxide film on the surfaces of both terminals is mechanically destroyed. In particular, contact reliability is improved even for different metal plating contacts.
