Abstract

The present invention provides a electrical connector for attenuating vibrations, in particular for the injector of a motor vehicle engine. The inventive connector comprises a locking device (13) for elastical interlocking which is provided with an axial stop surface (24) forming jointly with the associate stop surface of the complementary locking device (15) of a counterpart an mutual rest preventing the disconnection of the connector (1) and the counterpart (3). Said connector comprises an elastic vibration attenuating member (43) arranged in such a way that it produces the mutual elastic rest force of the stop surfaces (24, 65) when the connector (1) and the counterpart thereof are coupled. The invention can be used for connecting the injector of a motor vehicle internal combustion engine.

Description

technical field

[0001] The present invention relates to an electrical connector designed to be coupled with a counterpart of the connector by elastic interlocking along the coupling direction, for which purpose the electrical connector comprises locking by elastic interlocking and Means having an axial stop surface arranged to form, with a stop surface associated with a complementary locking means of a counterpart, a mutual support against disconnection of the connector and counterpart. Background technique

[0002] In certain applications in harsh environments, especially in the case of connection technology for the engine compartment of a motor vehicle, the quality of the electrical contacts can deteriorate rapidly and fail.

[0003] In the particular example of a connection device for an injector of an internal combustion engine, the connection socket fixed to the engine is subjected to high levels of vibration and also very high levels of temperature.

Embodiment Construction

[0026] An electrical connector consistent with a first embodiment of the invention is shown in FIGS. 1 to 6 .

[0027] In the example shown, the connector 1 is a two-way connector for an injector of a motor vehicle internal combustion engine, which connector is arranged to couple with a socket 3 ( FIGS. 5 and 6 ) forming the counterpart of the connector. .

[0028] In all the figures we introduce an X-axis which corresponds to the coupling direction and is oriented along the direction of the connector towards the receptacle engagement. The terms "front" and "rear" employed hereinafter should be understood in relation to this orientation, and it is assumed that the connector engages on the receptacle by a movement from rear to front.

[0029] The terms "axial" and "transverse" should also be understood in relation to this X-axis.

[0030] In a first embodiment of the invention represented in Figures 1 to 6, a connector 1 comprises a contact-carrying module 5 and a housing 7, ...
