Description

Electric-connected socket device

Technical field

The utility model relates to a kind of electric connector, is meant a kind of electric-connected socket device that supplies the joint grafting of signal line especially.

Background technology

Be used for the electric connector of the signal line connection of source of sound, owing to need to cooperate multiple signal line to connect, as loudspeaker, the earphone of multichannel, microphone ... Deng, use the above-mentioned equipment of connection so have a plurality of joints usually, so each joint all needs the signal line of corresponding particular appliance, and wrong plug then can't conducting.

In order to reach the convenience in the use, be that the user does not need corresponding correct jack to peg graft, but all admittances of can arbitrarily pegging graft, so the dealer designs a switching device on electric-connected socket device, insert by the joint of signal line and to touch this switching device, convert the suitable type of service that inserts to and can make wafer set on the motherboard go to elect, so, the user does not need corresponding jack, and admittance uses but can arbitrarily peg graft all.

Seeing also Fig. 1, is to be a kind of known electric connector, and it is to be provided with:

One plastics pedestal 10 which is provided with a plurality of jacks 11, and this jack is provided with the joint 12 that forward end is protruded; And

A plurality of switching devices, each switching device is corresponding each jack setting, it is provided with: a first terminal 13, it is provided with an elastic arm 14 and an extension 15, and this elastic arm 14 is that an end is fixed in plastics pedestal 10, and other end ejection formation has a plastics projection 18,15 one-tenth of this extensions are L shaped, be provided with transverse part 16 and longitudinal part 17, the end of transverse part 16 also is fixed in plastics pedestal 10 and contacts with elastic arm 14, and the not end of longitudinal part 17 forms pin and it is external to stretch out plastic seat; And one second terminal 20, it is provided with a longitudinal part 21 and a contact chip 22, this longitudinal part 21 is to form pin and stretch out plastic seat external for arranged side by side and lower end with the longitudinal part 17 of the first terminal 13, this contact chip 22 is vertically connected at the upper end of this longitudinal part 21, and can which is provided with a contact point 23 that protrudes up and down corresponding to the elastic arm 14 of this first terminal 13.

By above structure, when the joint 25 of signal line inserts connection, it can push this plastics projection 18, the elastic arm 14 times that makes the first terminal 13 is curved and contact conducting with second terminal 20, even so this switching device becomes the state of ON, and the joint 25 of this signal line can not contact with the first terminal 13 by plastics projection 18 separates at this moment, and it still can normally be electrically connected with signal terminal (figure does not show).
