The bracket is made of plastic materials; the bracket and the contact pin are fixedly connected through an injection way. Simultaneously, at the joint of the bracket and the contact pin, the bracket is provided with a tenon and the contact pin is provided with a groove; the tenon and the groove are matched; the tenon of the bracket is inserted into the groove of the contact pin; and thereby, the contact pin and the bracket are stably connected. A ground strip is attached to the surface of the bracket and is connected with the bracket through a clamping and connecting way. Compared with the prior art, the utility model can easily achieve the effects that the processing process is simple, the plate material is saved, the contact pin is thoroughly prevented from rotation and the plug bracket can easily pass through test certification in each country in the world.

Description

A kind of plug support

Technical field

The utility model relates to a kind of plug, especially relates to a kind of plug support.

Background technology

Contact pin adopts solid copper bar to make in the plug support of prior art, makes contact pin support production cost height, Heavy Weight; And the contact pin end will carry out round end and handle, and makes plug support complex manufacturing; Contact pin is directly fixedlyed connected with support in the prior art, when contact pin is connected with support when loosening, the contact pin of cylindrical shape be easy to rotate and above-below direction on move; In addition, the plug that utilizes prior art to produce is difficult to the test authentication by countries in the world, if make product will spend very high producing cost by various countries' test authentication.Therefore, the weak point of this type of contact pin support is: complex manufacturing, cost height, Heavy Weight, contact pin are connected the rotation and the moving and being difficult to authenticate by the test of countries in the world by the plug that prior art is made along the contact pin direction that can not prevent contact pin when becoming flexible with support.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, to society provide a kind of processing technology simple, save sheet material, thoroughly prevent the rotation of contact pin and moving and a kind of plug support by countries in the world test authentication easily along the contact pin direction.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of plug support comprises contact pin and support, and described contact pin also is connected in described support by the chase mortise structure.Described chase mortise structure constitutes described groove by the tenon on groove on the described contact pin and the described support and described tenon is complementary, and described chase mortise structure can prevent that described contact pin from rotating and moving along the contact pin direction.

The described contact pin of being made by the copper material stretching is fixedly connected on described support.Making described contact pin by banded copper material stretching is cylindrical shape.Described contact pin is a hollow structure.Because described contact pin is to be stretched by banded copper material to form, so contact pin inside is hollow structure, thereby raw material have been saved, make that the contact pin support is lighter, simultaneously, because form contact pin by banded copper material stretching, handle this operation so need not carry out contact pin end round end, make production process simpler.

Described hollow structure is filled with plastics.Though the hollow-core construction of described contact pin can be saved raw material, make that the contact pin support is lighter that simultaneously, the robustness of contact pin support also decreases.Plastics are filled with in hollow structure inside in the contact pin, thereby guaranteed the robustness of contact pin support.

Described contact pin adopts pouring type to be connected with described support.Make contact pin and support be connected and fixed and process simple.

Described contact pin surface attachment has conductive layer.Make the plug support have better conductivity.

Described plug support also comprises the ground strip that is attached on the described support, and described ground strip adopts snap fit to be connected with described support.Making utilizes plug of the present utility model to have higher fail safe.

Therefore, the utility model compared with prior art can reach processing technology simple, save sheet material, light, thoroughly prevent that contact pin from rotating and the moving and the effect by countries in the world test authentication easily of above-below direction.

Embodiment

Below, with specific embodiment the utility model is done being described in further detail in conjunction with the accompanying drawings.

With reference to Fig. 1 and Fig. 3, present embodiment is a kind of plug support, comprises contact pin 1 and support 2.Wherein, contact pin 1 is a cylindrical shape, is stretched by banded copper material and makes, thereby form the contact pin 1 with hollow structure, therefore can save material.Support 2 in the present embodiment is made by plastic material, and described support 2 is fixedlyed connected by the injection moulding mode with described contact pin 1.

See figures.1.and.2, in the junction of described support 2 and described contact pin 1, described support 2 is provided with tenon 6, and described contact pin 1 is provided with groove 7, and tenon 6 and groove 7 are complementary.Utilize the chase mortise structure to make that described support 2 is more stable with being connected of described contact pin 1, thoroughly prevented the rotation of contact pin.

With reference to Fig. 1, Fig. 3 and Fig. 4, in the hollow structure of contact pin 1, fill with plastics 3, make that the robustness of contact pin 1 is guaranteed in the present embodiment.One deck conductive layer 4 is electroplated on surface at contact pin 1 again.The conductivity of the contact pin 1 of present embodiment is further improved.

With reference to Fig. 1, Fig. 3 and Fig. 5, the surface attachment of described in the present embodiment support 2 has ground strip 5, and ground strip and support 2 are connected by snap fit, make and utilize the fail safe of plug of the present utility model to be improved.

Referring to figs. 1 through Fig. 4, the opening of contact pin 1 is the horn mouth structure in the present embodiment, and feasible connects more convenient quick.

Present embodiment is the contact pin support of French Standard model.

The concise and to the point production procedure of the utility model plug support is:

Step 1, utilize stretch banded copper material of punch press to form contact pin, test then;

Step 2, utilize the automatic lathe car to process support, test then;

Step 3, at the electroplating surface conductive layer of contact pin, test then;

Step 4, the inner injection moulding of past contact pin are tested then;

Step 5, punching press ground strip are tested then;

Step 6, support are poured into a mould with contact pin and are connected, and ground strip snaps fit onto on the support.

If when wherein not needing ground strip on the support, omit step 5.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
