Abstract

The utility model discloses a socket, including the pedestal, install left and right contact shell fragment in the pedestal and with left and right contact shell fragment cooperatees and constitutes the sharing ground connection shell fragment and the fixed ground connection shell fragment in return circuit, sharing ground connection shell fragment has one and adopts the arch of buckling the constitution, correspondingly fixed ground connection shell fragment's bounce position is equipped with a bellied little boss, when sharing ground connection shell fragment is static, its buckle the arch of constitution with little boss contactless. A pin which is electrically contacted with the shell and is convenient for soldering is also arranged in the seat body. Sharing ground connection shell fragment and fixed ground connection shell fragment, when not having the plug to insert, are contactless, consequently, the circuit of socket and electrical apparatus does not communicate, can not exert an influence to the electrical property of electrical apparatus, and through the position of contacting at two shell fragments sets up buckles and arch, can guarantee that the contact electrical property of shell fragment is good, and signal conduction is good.

Description

A kind of socket

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.

Embodiment

With reference to Fig. 1, shown in Figure 2, a kind of socket is provided, comprise pedestal 8, wrap in the metal shell 9 of pedestal outside, be installed in the left and right contact flat spring 2,3 in the pedestal 8 and match and constitute the shared grounding shell fragment 6 and the dead earth shell fragment 7 of one group of circuit with left and right contact flat spring 2,3.In pedestal 8, also be provided with one and electrically contact with housing 9, be convenient to the pin 1 of scolding tin, not be used in the outer surface scolding tin of housing 9.

With reference to Fig. 3, Fig. 4, shared grounding shell fragment 6 comprises elastic sheet body, adopt the phosphor bronze material, at the pin 601 that offers extended pedestal on the body and be used for fixing left and right sides grab 602,603 and outwardly directed elasticity contact arm 604 on pedestal, the front end of elasticity contact arm 604 constitutes a V-shaped structure by bending, and downward front end 606, make its have one with dead earth shell fragment 7 safe distance under static state; Vertically being shaped on of elasticity contact arm 604 has strengthening action together, and can keep the flange 605 of favorable elasticity state.

With reference to Fig. 5, Fig. 6, dead earth shell fragment 7 comprises elastic sheet body, adopt the phosphor bronze material, at the pin 701 that offers extended pedestal on the body and be used for fixing left and right sides grab 702,703 and outwardly directed elasticity contact arm 704 on pedestal, the leading portion of elasticity contact arm 704 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 a small boss 705, makes that the front end 606 with the v-shaped structure of shared grounding elastic part can keep excellent contact when being connected.
