Summary of the invention
The object of the present invention is to provide a kind of short circuit socket, to solve the problem causing connector construction complexity in prior art because back-moving spring need be arranged to realize short circuit between each contact.
In order to solve the problem, technical scheme of the present invention is:
A kind of short circuit socket, comprise socket insulator and at least two socket contact be arranged on socket insulator, socket insulator is provided with the spliced eye supplying the inserted terminal of corresponding plug to insert from front to back, socket contact comprises and is fixed on stiff end on described socket insulator and elastic suspended and extends in described spliced eye and the elasticity projecting end contacting conducting, elasticity projecting end is provided with the forced section making each elasticity projecting end separated from one another for the inserted terminal pushing tow by described plug, each elasticity projecting end contacts conducting with the corresponding plug contact of plug respectively afterwards separated from one another.
Each socket contact is chip-type contact.
The end of each elasticity projecting end is provided with the bending structure realizing Elastic Contact conducting and each socket contact and the conducting of corresponding plug contact Elastic Contact between each socket contact.
Described socket insulator is rectangular configuration, and the stiff end of socket contact is arranged on the long limit of rectangular configuration.
The front end of the minor face of socket insulator is provided with tapered guide structure.
The rear end of described insulator is fixedly installed the socket printed board that thickness of slab extends along the longitudinal direction, be fixed in described socket printed board after the stiff end of socket contact is passed by socket insulator from top to bottom, socket printed board is also fixed with two socket connector, socket printed board is provided with the socket printed circuit board connecting described socket connector and respective socket contact.
Described socket connector is RJ45.
Beneficial effect of the present invention is: the elasticity projecting end of each socket contact in the present invention contacts conducting in spliced eye, thus the short circuit function realized between socket contact, with plug to time slotting, forced section on the inserted terminal pushing tow elasticity projecting end of plug makes elasticity projecting end separated from one another, and elasticity projecting end contacts conducting respectively with the corresponding plug contact on plug subsequently.That is the short circuit in the present invention between each socket contact relies on the elasticity of socket contact self to realize, do not need additionally to arrange back-moving spring, between each socket contact, directly contact short circuit does not need to arrange short circuit printed board yet, and the structure of whole connector is simple.
