Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a connector in which a pin connector and a plug connector are removably fitted to each other.

"Prior Art" A fitting opening is formed in one end plate of a pin connector to which a pin contact is attached, a plug connector is inserted into the fitting opening from the insertion end side, and the plug contact and pin contact attached to the plug connector are inserted into the fitting opening from the insertion end side. Conventionally, connectors have been used in which corresponding ones of the connectors are electrically connected.

As this type of connector becomes smaller and the space it occupies decreases, its field of use is expanded, and for example, it is used for circuit parts of interior electronic devices of vehicles.

In this type of connector, it is necessary that the pin connector and the plug connector are completely fitted and that the fitted state is securely locked. Particularly when the connector is used in an interior electronic device of a vehicle, it is used in a state where there is a lot of vibration, so it is particularly necessary that the connector be completely fitted and locked.

What is shown in cross-sectional principle diagrams in FIGS. 2 and 3 is a fitting and locking means called a cantilever type lock, which is conventionally used in this type of connector.

In this cantilever type locking method, a protruding piece 13 is formed at the end of the upper plate 15 of the fitting opening 10 of the pin connector 11 so as to project into the fitting opening 10 .
On the other hand, when the plug connector 12 is mated, a plug connector 12 is provided on the upper surface 17 facing the inner surface of the upper plate 15 of the pin connector 11 as shown in FIG.
An engaging piece 16 is attached to the upper surface 17 so as to be elastically deflectable at right angles near the end surface in the direction of insertion into the pin connector 11 . An engagement protrusion 14 is formed on the engagement piece 16, and the engagement piece 1 of the engagement protrusion 14
In the insertion direction of 6, there is an engagement piece 16 with respect to the insertion direction.
A slope 14-T approaching .

When the plug connector 12 is inserted into the fitting opening 10 of the pin connector 11, the engagement protrusion 14 is pushed along the protrusion 13, and the engagement piece 16 is elastically biased. When the plug connector 12 is inserted until the proper mating state is reached, the plug connector 12 will be positioned over the engaging protrusion 14 or the protruding piece 13 as shown in FIG. 3, and in this state, the engaging piece 16 will elastically return to its original state. . In this position, the end surface of the plug connector 12 in the insertion direction and the end surface of the pin connector 11 facing the fitting opening 10 are in contact with each other.

In this fitted state, the pin contacts 18 of the pin connector 11 and corresponding plug contacts (not shown) of the plug connector 12 are electrically connected, respectively.

Conventionally, in this type of connector, pin connector 1
1 and the plug connector 12 is confirmed by the operation feeling when the engaging protrusion 14 and the protruding piece 13 are engaged.

However, the operating feel during engagement is not stable because it is supported at one point, and it is known that the operating feel changes due to changes in characteristics due to aging or the atmosphere in which it is used. In particular, when the operating atmosphere is in a high humidity state, the deformation of the engaging protrusion 14 and protruding piece 13 portion is large, and the operational feel during engagement is reduced.
Further, if the engaging protrusion 14 and the protruding piece 13 are deformed, the fitting may become incompletely locked, and the fitting between the pin connector 11 and the plug connector 12 may be released due to the application of external vibrations.

``Problems to be solved by the invention'' This invention aims to solve the aforementioned problems of the conventionally used connectors having poor operational feel and unstable mating locking. To provide a connector in which a user can reliably feel a fully fitted state with a plug connector during operation, and in which a pin connector and a plug connector can be stably fitted and locked.

"Structure of the invention" In this invention, a fitting opening is formed on one end surface of the pin connector, and a plug connector is inserted into this fitting opening from the insertion end side, so that the pin connector and the plug connector can be attached and detached from each other. The configuration is such that they fit together. When the pin connector and the plug connector are fitted together, corresponding pin contacts attached to the pin connector and corresponding plug contacts attached to the plug connector are electrically connected.

In this invention, an opening is formed in the plate part perpendicular to one end surface where the fitting opening of the pin connector is formed, and an engaging body is disposed within this opening, and the engaging bodies are formed at multiple locations around the periphery of the opening. It is integrally connected to the plate part by a thin plate-like connecting part and is held movably at right angles to the plate part.

On the other hand, a plurality of locking bodies are formed protruding from the opposing plate surface that faces the inner surface of the pin connector plate portion when the plug connector is fitted.

When the plug connector is inserted into the fitting opening of the pin connector, the engaging body of the pin connector is elastically biased in a direction away from the opposing plate surface by the locking body of the plug connector. When the plug connector is inserted into the pin connector to its proper position and the two are completely mated, the locking body moves over the engagement body and is located on the opposite side of the engagement body's mating opening. It is configured as follows.

When the pin connector and the plug connector are mated together, the locking body rides over the engaging body to provide sufficient operating contact to the operator. Further, when the pin connector and the plug connector are in a fitted state, the plurality of locking bodies are engaged with the engaging body, so that the fitted state between the pin connector and the plug connector is stably maintained.
