Abstract

The utility model discloses a plug which is arranged on an electric appliance and is used for plugging with a power supply plugboard. Two fixed grooves are mounted on a sidewall of an end of connection of pins and a plug body. The plug body is provided with two fixed projections matched with the two fixed grooves. As is known to all, almost all of the pins adopt a cylindrical or long plate-shaped structure. One end of the pin is connected with the plug body and the other end is a conductive end. In the above structure, the fixed grooves are matched with the fixed projections, a junction area between the pins and the plug body can be increased, junction intensity is raised and the circular pins can be carried out rotation position restriction. According to the above structure design, especially when the plug is plugged with the power supply plugboard, installation stability of the pins in the plug body can be guaranteed, generation of a condition that the pins shake and deviate from the plug body can be avoided, and use reliability of the plug provided by the utility model is raised.

Description

A kind of plug

Technical field

The utility model relates to the home appliance technical field, more particularly, and particularly a kind of plug.

Background technology

Plug is that electrical equipment common during people live forms one of member, and along with household electrical appliances are more and more higher to the current stability requirement, plug has also derived the various structures form thus.But according to GB, plug but is to change according to certain specification all the time.

Generally speaking, comparatively typical plug comprises pin and is used for installing the plug body of pin in the prior art, because the mode that pin is combined with plug body employing inserting, be very easy to cause plug in use, namely peg graft with electric socket or when extracting, shake to arrange between pin and the plug body and separate.So structural design not only causes the plug reduction in useful life easily, also has simultaneously certain potential safety hazard, causes easily the user to get an electric shock.

Therefore, serve describedly, how to solve the firm problem in joint portion between pin that plug exists and the plug body, become those skilled in the art's problem demanding prompt solution.

The utility model content

The technical problems to be solved in the utility model is for providing a kind of plug, and this plug is by its structural design, can solve the firm problem in joint portion between pin that plug exists and the plug body.

For solving the problems of the technologies described above, the utility model provides a kind of plug, be installed on and be used on the electrical equipment pegging graft with electric socket, comprise plug body and the pin that is connected with described plug body, have holddown groove on described pin and the end sidewalls that described plug body is connected, have the fixed lobe adaptive with described holddown groove on the described plug body.

Preferably, described holddown groove is two, and described holddown groove is symmetricly set on the described pin.

Preferably, described pin is cylinder type hollow copper pipe pin.

The utility model provides a kind of plug, is installed on the electrical equipment to be used for and electric socket is pegged graft, and has holddown groove on pin and the end sidewalls that plug body is connected, has the fixed lobe adaptive with holddown groove on the plug body.As a kind of general knowledge as can be known, pin adopts the structure of cylindric or long plate shape more, and the one end is connected with plug body, and the other end then is conducting end.The plug that the utility model provides, the end that pin is used for being connected with plug body has carried out architecture advances, so that have fixed slot configurations on the sidewall, and be provided with the fixed lobe adaptive with holddown groove at plug body, holddown groove is combined with fixed lobe, not only can increase the bonded area between pin and the plug body, improve its bond strength, can also carry out rotary spacing to the pin of circle.The said structure design especially in plug and electric socket grafting, more can guarantee the stability that pin is installed in plug body, avoid its situation that breaks away from plug body when arranging that shakes to occur, and has improved the reliability that the utility model uses.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to the accompanying drawing that provides other accompanying drawing.

Fig. 1 is the side-looking structural representation of plug among a kind of embodiment of the utility model;

Fig. 2 be among a kind of embodiment of the utility model plug face structural representation;

The corresponding relation of component names and Reference numeral is among Fig. 1 and Fig. 2:

Plug body 1; Pin 2; Holddown groove 3.

Embodiment

Core of the present utility model is for providing a kind of plug, and this plug is by its structural design, can solve the firm problem in joint portion between pin that plug exists and the plug body.

In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Please refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is the side-looking structural representation of plug among a kind of embodiment of the utility model; Fig. 2 be among a kind of embodiment of the utility model plug face structural representation.

The utility model provides a kind of plug, is installed on to be used on the electrical equipment pegging graft with electric socket, and for example, the utility model can be installed on the larger refrigerator of computer, printer even power consumption, the microwave oven.Comprise plug body 1 and the pin 2 that is connected with plug body 1, pin 2 is installed on the plug body 1, at first can be convenient to the grafting of the utility model and electric socket, and plug body 1 also has certain insulating properties, avoids user's electric shock situation to occur.In order to improve the steadiness that is connected and the reliability between pin 2 and the plug body 1, the utility model is on the basis of existing structure, plug has been carried out following structure optimization: have holddown groove 3 on pin 2 and the end sidewalls that plug body 1 is connected, have the fixed lobe adaptive with holddown groove 3 on the plug body 1.

As a kind of general knowledge as can be known, pin more than 2 adopts the structure of cylindric or long plate shape, and the one end is connected with plug body 1, and the other end then is conducting end.The plug that the utility model provides, the end that pin 2 is used for being connected with plug body 1 has carried out architecture advances, so that have holddown groove 3 structures on the sidewall, and be provided with the fixed lobe adaptive with holddown groove 3 at plug body 1, holddown groove 3 is combined with fixed lobe, not only can increase the bonded area between pin 2 and the plug body 1, improve its bond strength, can also carry out rotary spacing to the pin 2 of circle.The said structure design, especially in plug and electric socket grafting, more can guarantee the stability that pin 2 is installed in plug body 1, avoid its situation that breaks away from plug body 1 when arranging that shakes to occur, improve the reliability that the utility model uses.

Particularly, in an embodiment of the present utility model, pin 2 is cylindrical pin 2, and by said structure as can be known, holddown groove 3 can be rotated the location to columniform pin with the design of fixed lobe.
