Description

Cable connector

The utility model relates to a kind of cable connector, and it is good to refer in particular to a kind of structural strength and shield effectiveness, and can improve the cable connector of signal transmission quality.

Cable connector is to be used to provide being connected to each other between circuit arrangement, by the butt joint of terminal fitting and the signal conducting of electric wire cable, reach the signal transmission between two circuit arrangements, for example, general notebook computer is when its external soft magnetism disc player or printer, and wire and cable connector just provides the transmission medium between notebook computer and soft disc player; And the cable connector on its end limit of wire and cable connector connects because of direct and circuit arrangement, thereby it prevents that the design of electromagnetic interference from seeming important by contrast, the better quality of transmission signal to guarantee.

The purpose of this utility model is to provide a kind of cable connector good, that stablize shield effectiveness that has, with can effectively various telecommunications be disturbed by the ground connection eliminating, with the better quality of guaranteeing that signal transmits after another circuit arrangement connector dock.

The technical solution of the utility model is: it comprises circuit board, insulation shell, metallic shield lid, shell and cable, wherein this metallic shield lid leading edge is provided with one first kink, this first kink is formed with a contact-making surface, this contact-making surface is provided with the prominent point of several contacts, in addition, the ora terminalis of contact-making surface also is provided with second kink.

Owing to adopt feature structure of the present utility model, make cable connector have good, stable shield effectiveness, getting rid of with effectively various telecommunications being disturbed by ground connection after another circuit arrangement connector dock, with the better quality of guaranteeing that signal transmits.
