Coaxial cable connector

Technical field

The relevant a kind of coaxial cable connector of the utility model refers to that especially good combination is to make the coaxial cable connector that electric signal is transmitted between a kind of inner wire that guarantees splicing ear and coaxial cable.

Background technology

Many coaxial cables are used in the back panel wiring of information technoloy equipment (like mobile computer and miniaturized electronics), and this type of coaxial cable normally makes and is connected electrically to other cable conductor or substrate separately.

This type of coaxial cable is in order to be connected electrically to the conductor of another cable, and traditionally, the inner wire of coaxial cable is to be welded to other corresponding conductor separately one by one.Therefore, the inner wire of coaxial cable can be connected electrically to the conductor of other cable.

But, connection error takes place through regular meeting in this electric connecting mode in welding process, and promptly being electrically connected between the conductor of the inner wire of coaxial cable and other cable can't be operated accurate.

In addition because welding process is complicated, so welding process needs the long period, and this to be electrically connected process loss very big, the connection procedure situation of failing usually also can appear.

In order to overcome these problems, the conventional coaxial cable connector has been suggested the electrical connection arrangement as the conductor of the inner wire of coaxial cable and other cable.

United States Patent (USP) the 6th, 790 provides a kind of coaxial cable connector No. 082, and this connector comprises a splicing ear, can be connected to the inner wire of coaxial cable; One metal shell can be in order to support this splicing ear via an insulator.Wherein, this splicing ear makes it become bending by housing and insulator bending strength separately, so that a pair of contact chip of splicing ear is to the inner wire fixing of coaxial cable, and makes to form between inner wire and the splicing ear of coaxial cable and is electrically connected.

Clearly; The inner wire of this coaxial cable is electrically connected its formation by the method for clamping up and down of a pair of contact chip; Because this kind method of clamping is also insecure; Therefore can't guarantee being electrically connected between contact chip and inner wire for a long time, this will cause the phenomenon of loose contact, and then influence the Transfer Quality of signal.
