Abstract

The utility model discloses a plug with the anti-falling function, which comprises a socket and pins mounted on the socket. Clamping grooves are formed on the pins. The utility model has the advantages that the clamping grooves on the pins and a baffle at an insert on the socket can be matched, the plug can be firmly fixed in the socket and prevented from falling off, and the poor contact between the plug and the socket can be efficiently prevented, therefore electric equipment is protected, and great conveniences are brought to the work of workers at higher heights and facilitate improvement on working efficiency. The utility model has simple structure and low production cost.

Description

The plug that has the slip-off preventing function

Technical field

The utility model relates to the technical field of plug, more particularly relates to a kind of plug that can prevent effectively that plug from coming off in the socket.

Background technology

In daily work and life, we can touch multiple different charging equipment, and insert plug is that we all can experience every day, sometimes will run into because plug and socket loose contact even come off and can't normally make electrical appliance, also can burn electrical equipment under the serious situation, this is that the contact chip in the socket is aging and lose former elasticity, makes it can't clamp the pin of plug because the service time of plug and socket is longer on the one hand; Be because the quality of plug and socket own is just very poor on the other hand, the phenomenon that the reason of above-mentioned two aspects plug and socket loose contact all can occur even come off.Use electric hand drill or electric hammer when the higher position operation as the workmen, and plug and socket on the ground, the situation that if the plug and socket loose contact occurs even come off, the staff have to from eminence get off it is seated again after, return the higher position operation again, so again and again, not only increased staff's labour intensity, reduce operating efficiency, also had potential safety hazard simultaneously.

The utility model content

The purpose of this utility model is exactly in order to solve that loose contact can appear in above-mentioned plug and socket even the deficiency that comes off and provide a kind of simple in structure, and production cost is low, contacts the effective plug that has the slip-off preventing function.

The technical solution that the utility model adopts in order to solve above-mentioned deficiency is as follows:

The plug that has the slip-off preventing function, it is made of connector assembly and the pin that is installed on the connector assembly, offers draw-in groove on the described pin.

Described draw-in groove is " ∏ " font.

Described draw-in groove is " V " font.

Described draw-in groove is " ∠ " font.

Described draw-in groove is positioned at a side or the both sides of template pin.

Described draw-in groove is positioned at a side or the whole circumference place of column type pin.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the plate washer by spigot on the draw-in groove offered on the pin and the socket matches; just plug can be fixed in the socket firmly and can not come off; the phenomenon that has effectively prevented plug and socket loose contact produces; not only protected power consumption equipment; and for the staff of higher position operation; gone out to bring bigger convenience for their work; improved operating efficiency greatly; the utility model is simple in structure, and production cost is low.
