Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector having a structure in which contacts are short-circuited when not mated with a mating connector.

[0002]

2. Description of the Related Art In a connector used in various electronic devices, when this connector is not fitted with a mating connector, electronic circuits or parts connected to the connector are induced by current induced by external electromagnetic waves or static electricity. May malfunction. In order to prevent such inconvenience, there is a connector having a structure in which appropriate contacts among a plurality of contacts provided on the mating connector are short-circuited in a non-fitting state with the mating connector.

FIGS. 8 and 9 show a conventional example of such a connector. This connector 1 has an insulating housing 1
1. It comprises a conductive socket contact 12, a short-circuit contact 13, and the like. The socket contact 12
Contact accommodation chamber 111 formed in housing 11
And is connected to one end of the electric wire 14.
The short-circuit contact 13 is provided in a short-circuit contact accommodating chamber 113 formed in the housing 11. In the state shown in FIGS.
As shown in FIG. 0 (a), the contact portion 133 formed on the upper portion is open due to spring elasticity.

As a result, the contact portion 133 of the short-circuit contact 13 is always in elastic contact with the socket contact 12. As a result, via the short-circuit contact 13,
The socket contacts 12 provided in the adjacent contact accommodating chambers 111 are short-circuited. The contacts to be short-circuited are adjacent socket contacts in the illustrated example, but may be appropriately changed depending on the use state, use conditions, and the like.

On the other hand, a mating connector (not shown) is provided with an insulating member for releasing the above-mentioned short-circuit state. Then, when the mating connector is combined with the connector 1 and fitted, the above-described insulating member is inserted between the socket contact 12 and the short-circuit contact 13. At this time, the contact portion 133 of the short-circuit contact 13 is deformed downward and bent. Thereby, the short circuit between the socket contact 12 and the short-circuit contact 13 is released, and the pin contact (not shown) provided on the mating connector and the socket contact 12 are connected.

[0006]

However, in the above-mentioned conventional connector, when the connector is mated with the mating connector, the insulating member is guided to the contact portion of the short-circuit contact without any guidance. For this reason, the insulating member may not be able to be guided to a regular position depending on the combination state of the connector and the mating connector, and there is a problem that it is difficult to reliably release the short-circuit state.

In the conventional connector described above, when the insulating member comes into contact with the short-circuit contact, the tip of the contact portion of the short-circuit contact guides the insulating member.
This tip had to be lengthened to some extent. When the short circuit is released by the insulating member, the insulating member is not inserted into the correct position, and the contact portion of the short-circuit contact is forcibly pressed downward by the insulating member.
When the contact portion 133 contacts the bottom of the short-circuit contact 13 as shown in FIG. 7, the contact portion 133 may be deformed, and once the short-circuit contact 13 is deformed, the short-circuit contact 13 changes to the short-circuit state described above. Cannot be reproduced. Therefore, in order to prevent such deformation, the short-circuit contact is increased in the vertical direction. In the insulator, a deformation space for bending the contact portion of the short-circuit contact is used.
The space (particularly, the space in the vertical direction) needs to be large, and there is also a problem that the connector is correspondingly increased in size.

Further, when the mating connector is fitted, the contact portion of the short-circuit contact may be deformed by an external force transmitted through, for example, an insulating member.

According to the present invention, there is no problem as described above, a short circuit caused by a short-circuit contact can be reliably released at the time of mating with a mating connector, and the contact portion of the short-circuit contact can be prevented from being deformed by an external force. It is an object to provide a connector that can be reduced in size.

A connector configured to release a short circuit between the contact and the short-circuit contact by inserting an insulating member provided on the mating connector between the contact and the short-circuit contact And a guide wall for guiding the insulating member between the contact and the short-circuit contact is provided.

Here, the above-mentioned hole 114 is for the contact portion 133 of the short-circuit contact 13 to protrude from the contact short-circuit contact accommodating chamber 113 and to contact the contact 22.

The socket contact 12 of the connector 1
It has a substantially cylindrical shape. 2, an electric wire 14 is connected to the right end of the socket contact 12 by crimping or the like. The socket contact 12 is entirely locked in the above-described contact housing 111 by a housing lance 117 having elasticity. At this time, as shown in FIG. 2, the socket contact 12 communicates with the hole 112 at the left end thereof. The four socket contacts 12 are mounted in the respective contact accommodating chambers 111.

Referring to FIG. 6 further, the short-circuit contact 13 has a bottom 131, a spring piece 132 connected to the rear end of the bottom 131, a contact portion 133 connected to the spring piece 132, and both sides of the bottom 131. Side wall 134, bottom 1 connected continuously

Short circuit each other.

Then, the above-described connector 1 is accommodated in the connector accommodating chamber 211 of the mating connector 2 and both connectors are fitted. Then, the insulating member 214 provided on the mating connector 2 is inserted between the contact 12 and the short-circuit contact 13. Thereby, the contact portion 133 of the short-circuit contact 13 is pushed by the insulating member 214 from the state of FIG. 7A and is deformed downward as shown in FIG. 7B. Then, the insulating member 214 is interposed between the contact portion 133 of the short-circuit contact 13 and the socket contact 12, and the short-circuit between the contact 12 and the short-circuit contact 13 is released.

When the connector 1 and the mating connector 2 are mated, the lock projections 212 of the mating connector 2 and the lock engaging portions 115 provided on the lock lever 115 of the connector 1 are engaged. Thus, both connectors are locked to each other.

Here, in the above embodiment, the guide wall 13
Although 6 is formed on the short-circuit contact 13, other configurations are also possible. For example, a guide wall may be provided on the housing 11. Specifically, the housing 1
On the mating surface side of the first mating connector 2, a portion of the housing 11 may protrude upward from below the short-circuit contact housing chamber 113.

[0030]

According to the connector of the present invention, a guide wall is provided for guiding the insulating member of the mating connector between the contact and the short-circuit contact. Regardless of the combination state, the insulating member can be guided to a regular position, and the short circuit can be reliably released.

Further, since the insulating member is guided to the regular position by the guide wall, it is not necessary to lengthen the tip of the contact portion of the short-circuit contact. For this reason, the deformation space for spring deflection can be small, and the short-circuit contact can be reduced in the vertical direction, so that the connector can be downsized.

Further, since the short-circuit contact can be made smaller in the vertical direction and its contact portion can be shortened, there is an effect that deformation of the contact portion due to external force transmitted via an insulating member or the like can be prevented.
