Abstract

The utility model provides a self-locking power source connecting plug and mainly solves problems of the insecurity of the use of traditional plugs and traditional sockets. The structure of the self-locking power source connecting plug includes a connecting plug body. The connecting plug body is composed of a socket and a plug. The outer side of an insulator on the plug is provided with an elastic card extending outward. The card is in the shape of an inverted wedge. A clamping groove sinking inward is arranged on the outer side of a shell of the socket. The shape and the size of clamping groove are matched with the shape and the size of the card on the plug. The center of the socket is in the shape of a cylinder. A spring piece is installed in the cylinder. The inner wall of the cylinder and an inserting end of the plug are both provided with metal springs. The self-locking power source connecting plug provided by the utility model can realize grounding protection, dustproof and anti-touch protection and short-circuit protection effectively and can eliminate a phenomenon of sparkling on two electrodes when the plug is inserted. By adopting the self-locking power source connecting plug provided by the utility model, safety hazards caused by that the plug fall off from the socket under an effect of external forces when the self-locking power source connecting plug is in use can be eliminated.

Description

A kind of self-locking power plug joint

Technical field

The utility model relates to a kind of electric wiring connector, specifically a kind of self-locking power plug joint.

Background technology

Day by day universal along with household electrical appliance, socket also is connected to any place in the room more and more, conventional socket can be seen exposed sheet metal at the interface position, dust and small article all are easy to enter, the liquid of splashing also is easy to cause short circuit, more likely injure the children that curiosity weighs, so that the danger that generation is got an electric shock, the interface place also can be in the situation that often plugs rear appearance distortion.So the use of socket is especially for the family that child is arranged, the significant problem that can not be ignored really, if the protector of insulation is housed at the interface of socket, when realization is dustproof, touch-proof, more can eliminate the spark phenomenon when inserting plug, thereby eliminated many potential safety hazards, be bound to bring more safety guarantee to people's life, work.

The utility model content

The purpose of this utility model is to provide a kind of self-locking power plug joint, and this connection-peg has safety, self-locking, prevents the function that plug and socket are thrown off voluntarily.

The technical scheme in the invention for solving the technical problem is: a kind of self-locking power plug joint, its structure comprises the connection-peg body, described connection-peg body is made of socket and plug, the insulator outside on plug is provided with the elastic card of outside extension, this card is down wedge shape, hull outside at socket is provided with the draw-in groove that caves inward, card-like, size on this draw-in groove and the plug match, the center of socket is cylindrical shape, spring leaf is housed in the cylinder, is equipped with metal clips at the incoming end of cylinder inner wall and plug.

The beneficial effects of the utility model are: during use, when in the cylinder that the plug incoming end is inserted in the socket, spring leaf pressurized on the socket enters in the housing, metal clips on the cylinder inner wall is connected with metal clips on the plug incoming end, circuit is connected, and the elastic card on the plug enters the interior and locking of draw-in groove on the socket; Press the exposed parts of elastic card when pulling up plug, card is gathered to center position under pressure, and expanding force disappears, and can pull up plug this moment; The utility model can effectively be grounded protection, dustproof, touch-proof protection, short-circuit protection and eliminate the two poles of the earth spark phenomenon when inserting plug; prevention has also been eliminated the security hidden trouble that gets an electric shock; can prevent and when avoiding electricity consumption plug be subjected to External Force Acting in socket, to come off out and the security hidden trouble that causes; reduce the accident such as outage electric leakage and to the damage of electric equipment, raising safety in utilization.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1 socket, 2 plugs, 3 elastic cards, 4 draw-in grooves, 5 spring leafs, 6 metal clipss.

Embodiment

As shown in Figure 1: a kind of self-locking power plug joint, comprise the connection-peg body, described connection-peg body is made of socket 1 and plug 2, the insulator outside on plug 2 is provided with the elastic card 3 of outside extension, this card 3 is down wedge shape, hull outside at socket 1 is provided with the draw-in groove 4 that caves inward, card 3 shapes, size on this draw-in groove 4 and the plug 2 match, the center of socket 1 is cylindrical shape, spring leaf 5 is housed in the cylinder, is equipped with metal clips 6 at the incoming end of cylinder inner wall and plug 2.

During use, when in the cylinder that plug 2 incoming ends is inserted in the socket 1, spring leaf 5 pressurizeds on the socket 1 enter in the housing, metal clips 6 on the cylinder inner wall is connected with metal clips 6 on plug 2 incoming ends, circuit is connected, and the elastic card 3 on the plug 2 enters the draw-in groove 4 interior and lockings on the socket 1; Press the exposed parts of elastic card 3 when pulling up plug 2, card 3 is gathered to center position under pressure, and expanding force disappears, and can pull up plug 2 this moment; The utility model can effectively be grounded protection, dustproof, touch-proof protection, short-circuit protection and eliminate the two poles of the earth spark phenomenon when inserting plug; prevention has also been eliminated the security hidden trouble that gets an electric shock; can prevent and when avoiding electricity consumption plug be subjected to External Force Acting in socket, to come off out and the security hidden trouble that causes; reduce the accident such as outage electric leakage and to the damage of electric equipment, raising safety in utilization.

Claims
