Electrical connector assembly

The present invention relates to an electrical connector assembly, and more particularly to an input/output interface on a consumer electronic product.

Electrical connectors are widely used as input/output (I/O) interfaces in consumer electronic devices such as notebook computers and multimedia players (MP3, MP4). More and more consumer electronics products are now required to be waterproof. The insulative housing of the electrical connector that does not have the waterproof function is provided with a plurality of receiving slots for receiving the conductive terminals, and the receiving slots communicate with the outside to facilitate the mounting of the conductive terminals into the receiving slots from the corresponding surfaces. However, in some environments, the external water vapor easily enters the receiving cavity through the receiving groove, thereby causing damage to the interior of the electronic product. In order to prevent the ingress of water vapor, the prior electronic devices often adopt an external interface covering the connector, but this has the disadvantages of inconvenient assembly and high cost.

In view of this, it is necessary to design an electrical connector assembly that can solve the above drawbacks.

It is an object of the present invention to provide an electrical connector assembly having a waterproof function.

The electrical connector of the present invention can be implemented by the following technical solution: an electrical connector assembly includes: an insulative housing having an insertion opening at a front end thereof, the insertion opening extending inwardly to form a receiving cavity to receive the electrical connection The insulative housing includes a mounting wall, and the mounting wall is recessed inwardly with a plurality of receiving slots communicating with the receiving cavity; the conductive terminal is retained by the The insulative housing is respectively mounted in the receiving slot and is provided with a contact portion protruding into the receiving cavity to be in contact with the plug and a soldering portion extending outwardly from the mounting wall; The electrical connector assembly further includes a gasket attached to the mounting wall of the insulative housing and covering the receiving cavity, and a cover attached to the sealing mat and cooperating with the insulating body.

Compared with the prior art, the gasket of the electrical connector assembly of the present invention covers the mounting wall and the cover presses the sealing gasket against the mounting wall to tightly seal the terminal groove. This sealing method, even for a large water pressure Under the same, a better waterproof effect can be achieved, and the installation is convenient and the cost is low.
