Abstract
The utility model discloses a socket. The socket comprises a socket body, a left contact spring, a right contact spring, a shared grounding spring plate, and a solid grounding spring plate, wherein, the left and the right contact springs are mounted in the socket body; the shared grounding spring plate and the solid grounding spring plate form a loop with the left and the right contact springs; the shared grounding spring plate is provided with a protrusion formed by bending; correspondingly, a small raised lug boss is arranged at the bouncing part of the solid grounding spring plate; when the shared grounding spring plate is stock-still, the protrusion cannot contact the small lug boss; and a pin which is in electric contact with a housing and provides convenience for soldering is also arranged in the socket body. As the shared grounding spring plate and the solid grounding spring plate cannot contact each other when no plug is inserted, the socket is not communicated with the circuit of an electric appliance, and cannot generate impact on the electrical property of the electric appliance; and by arranging the bending part and the protrusion at the contact part of the two spring plates, the contact electrical property of the spring plates are ensured to be well, and the signal conduction is ensured to be good.
Description
Technical field
The utility model relates to the annex that can be installed in the host computer, is specifically related to a kind of socket that matches with aperture 3.5mm plug and use.
Background technology
In the prior art, a kind of socket annex that is installed in the multiple electrical equipment is arranged, commonly a kind of aperture 3.5mm socket, this socket is by pedestal, is installed in the left and right contact flat spring in the pedestal and shared grounding shell fragment and the dead earth shell fragment that constitutes the loop that match with left and right contact flat spring constitutes; Be used to export the audio signal of left and right acoustic channels.
The utility model content
The purpose of this utility model is, a kind of socket is provided, and the electric property of this socket is good, the good springiness of contact chip, and conduction property is good, and is convenient to install.
The technical scheme that the utility model provides is as follows: a kind of socket, comprise pedestal, wrap in the metal shell of pedestal outside, be installed in the left side in the pedestal, right contact flat spring and with a described left side, right contact flat spring matches and constitutes the shared grounding shell fragment and the dead earth shell fragment of one group of circuit, described shared grounding shell fragment has a projection that adopts bending to constitute, accordingly, be provided with the small boss of a projection at the position of upspringing of described dead earth shell fragment, the end of described shared grounding shell fragment is in when static, the projection that its bending constitutes does not contact with described small boss, in described pedestal, also be provided with one and electrically contact with described housing, be convenient to the pin of scolding tin.
In the socket of above-mentioned aperture, described shared grounding shell fragment comprises elastic sheet body, offer the pin of extended described pedestal on the body and be used for fixing grab and outwardly directed elasticity contact arm on pedestal, the front end of elasticity contact arm constitutes the front end of a V-shaped structure by bending, the elasticity contact arm vertically be shaped on the flange that has booster action together.
In the socket of above-mentioned aperture, described dead earth shell fragment comprises elastic sheet body, offer the pin of extended described pedestal on the body and be used for fixing grab and outwardly directed elasticity contact arm on pedestal, the front end of elasticity contact arm constitutes one by bending and is upturned, be similar to the front end of Z-shaped structure, the upper surface of front end is provided with small boss.
The utlity model has following advantage: shared grounding shell fragment and dead earth shell fragment, when not having plug to insert, be discontiguous, prevent that misconnection from touching, when plug inserted, the earth terminal of plug was connected with shared grounding elastic part, simultaneously because the squeezing action of plug, make shared grounding shell fragment contact with the dead earth shell fragment conducting and ground connection simultaneously, be convenient to the pin of frame ground, the convenient installation by soldering owing to increased by one.
