Abstract

The utility model relates to an interlock plug and a socket, wherein a jack 1 is arranged on a socket panel, and the plug comprises a plug upper body 2 and a pin 5. the utility model is characterized in that the plug further comprises a liner 3 and a lock sleeve 4, wherein the outer edge of the bottom portion of the lock sleeve is extended with a lock head 6, the lock sleeve is sleeved outside the liner, the upper portion is equipped with a pressing ring 7 which is inwardly extended presses the upper edge of the liner and just be pressed by the plug upper body 2, and a locating ball 10 is further arranged on the lock head 6. The socket panel is equipped with a lower concave surface and a lock slot 11 which correspond to the plug, and a locating hole 12 which corresponds to the locating ball of the lock head is arranged in the lock slot. Through using the interlock plug and the socket, the lock head is locked in the lock slot which corresponds to the socket panel through rotating the lock sleeve, and the plug and the socket can be closely locked and do not loose through that the locating ball is matched with the locating hole.

Description

The interlocking plug and socket

Technical field

The utility model relates to a kind of attaching plug and socket.

Background technology

The metal pin of known attaching plug is not because tight with the engagement of the copper sheet of socket, occurs looseningly sometimes, even comes off from socket, causes circuit contacts bad or open circuit, and causes the electrical equipment can't operate as normal.Firmly involve when using electric tool as fitting-out work teacher, or connect the electric equipment that produces vibrations, cause plug to come off especially easily, thereby reduce operating efficiency from socket.Because plug under the "on" position and socket engagement are not tight, very easily produce electric arc, cause serious accidents such as fire.

For solving this difficult problem, the direction that people make great efforts mainly is to improve the material and the shape and structure of metalwork, as adopt elasticity tin-phosphor bronze preferably, change the shape and structure of socket copper sheet and increase its thickness etc., but because the frequent plug between plug and the socket, the tin-phosphor bronze sheet also can lose its original elasticity, and useful life is limited, can't solve loosening and this root problem that comes off.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of attaching plug that can lock mutually and socket.

The interlocking plug and socket, comprise plug and socket, socket panel has jack, and plug comprises plug upper body and pin, and pin is corresponding with the jack of socket, it is characterized in that plug also comprises inner bag and lock sleeve, pin passes from the inner bag bottom surface, and there is the tapered end that stretches out outer, lock sleeve bottom, and the lock sleeve socket outside the tank, the trim ring of stretching in the band of top is not only pushed down the inner bag upper edge but also is just pushed down by the plug upper body, also has positioning bead on the described tapered end; Described socket panel have with the corresponding concave surface of plug and with plug on the corresponding locked groove of tapered end, band and tapered end positioning bead corresponding positioning hole in the locked groove.

Along the bottom rotary stopper tooth is arranged in the described trim ring, inner bag upper edge and rotary stopper tooth opposite position have the rotary stopper groove;

The pin of described plug can be two pins, also can be three pins; The jack of described socket also can be corresponding two jacks and three jacks.

Adopt the interlocking plug and socket of this structure, need only rotation lock cover behind the plug insertion socket, make tapered end lock corresponding locked groove on the socket panel, positioning bead cooperates with location hole just can make plug and socket locking and loosening.And just can unlock behind the reverse rotation lock sleeve, plug is pulled up from socket.This interlocking plug or socket can also be general with conventional socket or plug, just do not have interlock function.
