Abstract

The utility model provides an adapter, belonging to parts for interconnection or transmission of information or other signals between electrical appliance input/output equipment or processing unit. The adapter consists of a socket and a plug, wherein the socket and the plug respectively comprise a hollow shell; the inner hole of the shell is internally provided with a hollow metal main body in which a PIN is arranged; the metal main body is isolated from the PIN by an insulator; the adapter is characterized in that the shell of the socket is provided with a cantilever type elastic flap; the front end of the elastic flap is provided with an orifice; a convex edge is arranged above the middle part of the plug; the orifice of the elastic flap of the socket is matched with the convex edge of the plug; and the convex edge on the plug can be clamped into the orifice on the shell of the socket. The adapter can lead the plugging of the plug and the socket to be compact, and can not cause separation and bad contact due to separation in the using process.

Description

Adapter

[technical field]

The utility model relates to information or the interconnection of other signals or the parts of transmission between input-output apparatus or the processing unit, refers to a kind of adapter especially.

[background technology]

Adapter includes a socket and a plug, the input/output circuitry that connects two equipment or two processing units respectively, during use the front end of plug is inserted in the socket, be used for the information between these two equipment or the processing unit or the mutual transmission of other signals.Socket, plug comprises a hollow casing respectively, hollow metal master is housed in the shell endoporus, the PIN pin is arranged in the metal master, metal master is by insulator and PIN pin isolated insulation, the PIN pin of socket has pin hole, plug PIN pin is not with holes, the metal master internal diameter of socket and the metal master external diameter of socket are suitable, when during use plug head being inserted socket, the PIN pin that the metal master of plug inserts the interior plug simultaneously of metal master of socket inserts in the pin hole of socket PIN pin, and the PIN pin of socket and plug is electrically connected, the metal master of socket and plug is electrically connected.When using, mainly leans on the adapter of prior art of the metal master clamping of the resilient clamp power of socket metal master with plug, making it unlikely comes off, but because the elastic force of socket metal master is limited, the chucking power that can be directed at socket metal master endoporus after long-time use or the regular plug descends, and causes the consequence that gets loose with loose contact.

[summary of the invention]

The purpose of this utility model is to provide a kind of can make the plug and socket grafting compact, can in use not get loose and the adapter that can not cause loose contact because of getting loose.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of adapter is provided, comprise socket and plug, socket, plug include hollow casing respectively, hollow metal master is housed in the shell endoporus, the PIN pin is housed in the metal master, metal master is characterized in that by insulator and PIN pin isolated insulation; One cantilever type elasticity lobe is arranged on the jack housing, and this elasticity lobe front end has an aperture, and there is a convex edge top, the middle part of plug, and the aperture of described socket elasticity lobe and the convex edge on the described plug match, and the convex edge on the plug can snap in the aperture on the described jack housing.

During use with in the plug head socket, plug PIN pin is inserted in the socket PIN pin hole, the plug metal master inserts in the socket metal master and is electrically connected, simultaneously under the convex edge card on the plug body on the socket in the aperture of elasticity lobe, plug just can not retreat like this, so that plug and socket is pegged graft compact, can in use not get loose and can not cause loose contact because of getting loose, in the time of need withdrawing from socket elasticity lobe is outwards started, make the convex edge on the plug break away from elasticity lobe aperture, can smoothly plug be transferred to.

Can left-right rotation when further assurance socket and plug is pegged graft, on the jack housing endoporus, have chute, in plug head the guide rail suitable with this chute arranged, guide rail moves along chute when plug insertion socket, make in the plug insertion socket, guide rail cooperates chucking with chute, plug can not rotated in socket.

The beneficial effects of the utility model are: plug and socket is pegged graft compact, can in use not get loose and rotate, can not cause loose contact because of getting loose.

[embodiment]

Referring to accompanying drawing, the utility model adapter comprises socket and plug, socket, plug include

hollow casing

11 or 21 respectively,

hollow metal master

13 or 23 are housed in the

shell

11 or 21,

PIN pin

12 or 22 are housed in the metal master, metal master is characterized in that by

insulator

16 or 24 and PIN pin isolated insulation; One cantilever type elasticity lobe 111 is arranged on the jack housing 11, this elasticity lobe front end has an aperture 112, there is a convex edge 211 top, middle part of plug, the aperture 112 of described socket elasticity lobe 111 matches with convex edge 211 on the described plug, and the convex edge 211 on the plug can snap in the aperture 112 on the described jack housing.
