Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal for preventing an electronic circuit or the like connected to a connector from malfunctioning due to a current induced by electromagnetic waves or static electricity from the outside when the male and female connectors are not fitted. Of the short-circuit member.

[0002]

2. Description of the Related Art Conventionally, when inspecting electrical equipment mounted on an automobile or the like, a male and female connector housing in a fitted state connecting a signal line on the power source side and a signal line on the equipment side is disengaged. At this time, the male and female connection terminals fitted and inserted in the connector housing are in an open state. When the connection terminal is open like this, if there is something charged with static electricity in the vicinity of this connection terminal, or if the connection terminal on the device side receives an electromagnetic wave from the outside, a magnetic field or electric field will be induced, and the signal A minute current temporarily flows through the line. Therefore, an electrical equipment such as an air bag that is driven by a small current may malfunction due to the small current.

In order to prevent malfunction of the above-mentioned electrical equipment, there has been proposed one in which adjacent connecting terminals in the connector housing are short-circuited by a short-circuit member. As shown in FIG. 6, the female connector housing 1 has a housing insertion chamber 5 into which a mating male connector housing 2 is inserted at the front end portion.
Is opened, and the male terminal 3 to which the connection electric wire W is crimped is inserted from the rear end portion. The male terminal 3 and the female terminal 4 fitted into the mating male connector housing 2 are electrically connected by mutual fitting of the male and female connector housings 1, 2.

In the female connector housing 1, a short-circuit member 36 made of a conductive material for short-circuiting the male terminals 3 and 3 which are fitted and inserted adjacently to each other is mounted. The short-circuit member 36 is a flat plate-shaped short-circuit portion 38 having a locking hole 38a for locking the inner wall surface of the female connector housing 1, and the short-circuit portion 38 is integrally punched and bent into an oval shape. It is composed of a pair of elastic contact pieces 37, 37.

As shown in FIG. 7, the assembly procedure is such that the short-circuit member accommodating chamber 9 is continuously provided at a position adjacent to the housing insertion chamber 5 into which the mating male connector housing 2 of the female connector housing 1 is inserted. There is. The short-circuit member 36 is mounted through the rear opening of the short-circuit member accommodation chamber 9 before the male terminal 3 is inserted. Then, the male terminal 3 is inserted into the terminal accommodating chamber 11 through the rear end opening of the female connector housing 1.

At this time, the connecting portion 3a at the tip of the male terminal 3
While protruding into the housing insertion chamber 5, the connecting portion 3
One surface of a is pressed against the elastic contact piece 37 of the short-circuit member 36. As a result, both male terminals 3 are connected to the short-circuit member 36.
As a result, a short circuit occurs, and a minute current that causes malfunction does not flow.

After that, when the male connector housing 2 with the female terminals 4 inserted therein is inserted into the housing insertion chamber 5, the front end portion 2a of the male connector housing 2 contacts the elastic contact piece 37. Furthermore, the male connector housing 2
Is inserted, the elastic contact piece 37 is bent in a direction away from the connecting portion 3a. Then, when the mutual connector housings 1 and 2 are completely fitted, the elastic contact piece 37 in the bent state abuts on the outer wall of the male connector housing 2. As a result, the short-circuiting function of the short-circuit member 36 is completely released, and the connecting portion 3a of the male terminal 3 is fitted into the connecting portion 4a of the female terminal to complete the conductive connection.

[0008]

However, in the bent elastic contact piece 37 as shown in FIG.
When inserting the male terminal 3, the tip of the connecting portion 3a may come into contact with the bent portion 37a of the elastic contact piece 37, and the male terminal 3 may not be inserted any more, which is a so-called dock phenomenon. There is.

Therefore, before the male terminal 3 is inserted, the mating male connector housing 2 is inserted, the elastic contact piece 37 is retracted to a position where the dock phenomenon does not occur, and the male terminal 3 is inserted. I'm taking steps like this. Therefore, workability at the time of maintenance becomes very poor. Further, if the male connector housing 2 is forgotten to be inserted, the short-circuit member 36 itself may be deformed by the male terminal 3 or may be damaged in some cases.

An object of the present invention is to solve the above-mentioned problems, and a short circuit for a terminal in which the work of inserting a connection terminal into a connector housing can be performed easily and surely without being obstructed by a short circuit member. It is to provide a member.

[0011]

The above object of the present invention is to provide a position adjacent to a terminal accommodating chamber in which a plurality of connecting terminals are fitted and inserted in either one of the connector housings of the male and female connectors which are fitted to face each other. In the short-circuit member for a terminal, which is provided in the short-circuit member accommodating chamber, the short-circuit member accommodating chamber is provided, and a short-circuit member that press-contacts a plurality of connection terminals fitted in the terminal accommodating chamber to short-circuit the connection terminals is provided. This can be achieved by a short-circuit member for a terminal, characterized in that the elastic contact piece that is in pressure contact with the connection terminal can be displaced in the outer direction of the connector housing with respect to the pressing force received from the longitudinal direction of the connector housing.

Another object of the present invention is to provide a short-circuit member accommodating chamber at a position adjacent to a terminal accommodating chamber in which a plurality of connecting terminals are fitted and inserted in either one of the connector housings of the male and female connectors fitted to face each other. For the terminal, which is provided in the short-circuit member accommodating chamber, press-contacts a plurality of connecting terminals fitted in the terminal accommodating chamber to short-circuit the connecting terminals, and the press-contact state is separated as the other connector housing is fitted. In the short-circuit member, the short-circuit member includes a short-circuit portion mounted on the inner wall of the connector housing and an elastic contact piece that press-contacts the connection terminal to be short-circuited, and the tip of the connection terminal when the connection terminal is inserted from the rear end of one connector housing. This can be achieved by a short-circuit member for a terminal, characterized in that the elastic contact piece is provided with an inclined surface for displacing the elastic contact piece in the retreat direction by the portion.

The above object can be achieved more effectively by providing the guide plate near the tip of the connecting terminal of the elastic contact piece.

[0014]

In the short-circuiting member for a terminal having the above-described structure according to the present invention, the elastic contact piece which is in pressure contact with the connection terminal of the short-circuiting member is in the outward direction of the connector housing against the pressing force received from the longitudinal direction of the connector housing. It is configured to be displaceable. As a result, when the connection terminal is inserted from the rear end of the connector housing, the elastic contact piece is displaced in the outward direction of the connector housing without disturbing the connection terminal insertion while being pressed against the tip of the connection terminal. The property is improved. Further, the elastic contact piece pressed against the connection terminal as the mating connector housing is inserted is displaced outward of the connector housing and separated from the connection terminal. Therefore, the short-circuit function of the short-circuit member is surely released by fitting the connector housings together.

Further, in the short-circuit member for a terminal having the above-mentioned structure according to the present invention, the short-circuit member is composed of a short-circuit portion mounted on the inner wall of the connector housing and an elastic contact piece press-contacted to the connection terminal to be short-circuited. The elastic contact piece is provided with an inclined surface for displacing the elastic contact piece in the retracted direction by the tip portion of the connection terminal when the connection terminal is inserted from the rear end of the housing. As a result, when the connection terminal is inserted from the rear end of the connector housing, the tip of the connection terminal abuts the inclined surface of the elastic contact piece, and the elastic contact piece presses the tip of the connection terminal with the insertion of the connection terminal. In that state, it is displaced in a direction that does not hinder the insertion of the connection terminal. Therefore, the insertability of the connection terminal into the connector housing is improved.
