Description

Electric connector

Technical field

The utility model relates to a kind of electric connector, is meant a kind of electric connector 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 ... etc., 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 connector, joint by signal line inserts this switching device of shake-up, convert the suitable type of service that inserts to and can make chipset on the motherboard go to elect, so the user does not need corresponding jack, and admittance uses but can arbitrarily peg graft all.

See also Fig. 1, be a kind of known electric connector that is provided with switching device, it is to be provided with:

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

Several 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 20 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 curved and with the second termination contact conducting, 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).

Above-mentioned known electric connector has following shortcoming:

1. it is ejection formation one a plastics projection 18 on the first terminal on making, and so make very tired Xu and difficult, and production capacity speed is slow, causes the increase of cost.(, above-mentioned disappearance then being arranged) if need that metal terminal is put into the ejaculation of mould do because jet-out plastic is easy and quick merely.

2. because the first terminal 13 is very difficult as if wanting direct jet-out plastic projection 18, so need be cut into two sections is elastic arm 14 and extension 15, remove jet-out plastic projection 18 with short elastic arm 14 again, though so can reduce the degree of difficulty of ejaculation, so but make the first terminal become two members to remake assembling, increased cost in the manufacturing.
