Abstract

The utility model relates to a dipolar plug cover. The utility model is characterized in that a coupling head of a connecting line enters from a round hole A of a plug cover main body. When a groove of the coupling head passes through the lower part of a spring lamination, a bump of the spring lamination is clamped into the groove of the coupling head, owing to the spring function of the spring lamination. Therefore, the coupling head of the connecting line can be firmly fixed in the dipolar plug cover, and the coupling head can not fall off. The utility model has the characteristic of integral forming, the manufacture is easy, and the cost can be reduced. Because the coupling head is firmly fixed in the dipolar plug cover, a packed socket can not generate the situation of the bad contact or the shedding of the connecting line, and the utility model has the practicality.

Description

The two poles of the earth plug cover

The utility model relates to the plug cover that a kind of the two poles of the earth plug is used.

As shown in Figure 1, it is combined general used the two poles of the earth plug cover by a plug cover body 1 and a loam cake 2, and other cooperates Fig. 2, shown in Figure 3, is this two poles of the earth plug cover and connecting line 8 junctures, it is characterized in that:

Wherein the joint 9 of this connecting line 8 is that U type groove 6 by plug cover body 1 enters, and then pass the circular hole 10 of this plug cover body 1, and by the salient point 3 of this loam cake 2 and jack 4 combinations of plug cover body 1, and can snap in the groove 7 of joint 9 by the baffle plate 5 of this loam cake 2, the joint 9 of this connecting line 8 can be encapsulated in the plug cover of the two poles of the earth, again because general used the two poles of the earth plug cover is to adopt plug cover body 1 and loam cake 2 compound modes, and only depend on the salient point 3 of loam cake 2 to combine with the jack 4 of plug cover body 1, the shortcoming that this loam cake 2 is come off easily and lose is arranged, do not have a practicality;

The shortcoming of used plug cover:

1, the shortcoming that comes off easily and cause loose contact is arranged.

2, formed by several parts, the shortcoming of easy loss is arranged.

3, its production process complexity, and cost height.

4, production process must be by manpower.

5, do not have a practicality.

6, do not have a progressive.

7, lack industrial competitiveness.

Therefore, how above-mentioned shortcoming is forgone, be the technological difficulties place that the utility model institute desire solves.

Primary purpose of the present utility model is to provide a kind of easy making, the two poles of the earth plug cover that cost is low, and the joint of the connecting line in the plug cover of the two poles of the earth is firmly to be fixed in the plug cover of the two poles of the earth, can not to come off and not have the situation that loose contact or connecting line come off to take place.

Above-mentioned purpose of the present utility model is realized by following technical scheme.

A kind of the two poles of the earth plug cover, it is characterized in that: be the structure that is formed in one, this plug cover body one end left side wherein, part on the right side and be not provided with circular hole B, this circular hole B communicates with this plug cover body other end circular hole A, and at plug cover body one end, a left side, on between the right circular hole B, be concaved with separation trough down respectively, above this plug cover body other end, locate again, a left side, part on the right side and be not provided with strip hole A, and extend a shell fragment to strip hole A from this plug cover body and strip hole A joint, and this shell fragment one end convexes with a projection in circular hole A, between two shell fragments, be provided with correcting hole A again, this correcting hole A communicates with the correcting hole B at the back side, in addition, this circular hole A left side, right both sides then are respectively equipped with strip hole B.

Wherein the joint of this connecting line is that circular hole A by the plug cover body enters, it is entered in this circular hole at leisure, just when the groove of this joint during through the shell fragment below, be because of this shell fragment elastic force effect, and the projection that makes this shell fragment sticks in the groove of joint, and then make the joint of this connecting line can more firmly be fixed in the plug cover of the two poles of the earth, do not come off, again, the integrated characteristic of tool is not only made easily, can reduce cost again, in addition, via the socket after the encapsulation, because of this connector firmly is fixed in the plug cover of the two poles of the earth, so do not have the situation generation that loose contact or connecting line come off, dark tool practicality effect.Therefore advantage of the present utility model is as follows:

1,, do not take place so do not have the situation that loose contact or connecting line come off because of connector firmly is fixed in the plug cover of the two poles of the earth.

2, integrated characteristic is not only made easily, and can be reduced cost.

3, tool comprehensive automation, and avoid waste of manpower resource.

4, tool practicality.

5, tool progressive.

6, value on tool business circles and the industrial circle.

Convenient understand content of the present utility model for making, and the effect that can reach, conjunction with figs. is enumerated a specific embodiment now, introduction is described as follows in detail:
