Description

Cable connector combination

The present invention relates to a cable connector assembly, and more particularly to a cable connector assembly that can transmit signals at high speed.

The cable connector assembly includes an electrical connector and a cable that connects the electrical connector. Typically, the cable connector combination also includes a strain relief for reducing stress when the cable is connected to the electrical connector. U.S. Patent No. 5,383,796 discloses a metal strain relief comprising an intermediate portion partially covering one side of the cable and a pair of wings extending outwardly from opposite sides of the intermediate portion. Each wing has a receiving hole. The stress relief member is locked to the housing of the electrical connector by a pair of screws that pass through the receiving hole. However, when the stress relief member is locked to the housing, the cable between the stress relief member and the housing may be subjected to a great external force and damaged to affect the data signal transmission performance of the cable. In addition, due to the gap between the stress relief member, the cable, and the housing, the electromagnetic interference of the cable connector combination cannot be completely covered, and thus cannot be applied in an environment of high speed transmission.

The Chinese Patent Publication No. CN2891361Y discloses a stress relief member for protecting a conductive core of a cable, the stress relief member comprising a U-shaped metal retaining member and a metal hoop, the retaining member and the hoop being both of a certain hardness. Made of metal. The hoop is placed between the conductive layer of the cable and the metal braid. The holding member has a bow-shaped pressing portion and a pair of positioning portions extending downward from the pressing portion, the positioning portion of the holding member is inserted into the receiving groove of the housing, and the pressing portion is tightly pressed against the cable. On the metal braid, such that the metal braid is tightly sandwiched between the retaining member and the hoop, and the conductive core is isolated within the hoop without damage. However, when installing the hoop, the wall of the hoop The thickness is thin and it is not easy to apply force and is difficult to position, resulting in many inconveniences in installation.

Therefore, it is necessary to provide an improved cable connector combination to overcome the aforementioned drawbacks of the aforementioned connectors.

It is an object of the present invention to provide a cable connector assembly having a strain relief that can be easily installed.

To achieve the foregoing objective, the present invention adopts the following technical solution: a cable connector assembly, including an electrical connector, comprising a connector module and a body covering the connector module, the body being provided with a cable outlet; The cable has a plurality of wires electrically connected to the electrical connector, the wires being electrically connected to the connector module, the cable having an insulating outer cover and passing through the cable outlet; a stress releasing member, The utility model comprises an inner holding portion for isolating the wire of the cable and an outer holding portion of the insulating outer covering of the covering cable, and the inner holding portion and the outer holding portion are integrated by the connection of the connecting portion.

Compared with the prior art, the cable connector assembly of the present invention is integrated into the inner holding portion and the outer holding portion, which facilitates the installation and positioning of the inner holding portion, and has a simple structure and convenient processing.
