Background technique

Press, the traditional connector head on the market generally, please refer to the known technology shown in Figure 1, as shown in the figure, a connector body 10 has a plurality of metal contacts 12 at the front end, and the connector body The front metal contact 12 of 10 is covered and fixed, effectively separating the electrical contact between the metal contact 12 and the metal contact 12, and then plugging into the connector at the other end can avoid electrical interference caused by the metal contact 12 being too close .

However, the above-mentioned connector body 10 has the following disadvantages. During the use of plugging and unplugging, the exposure of the metal contact 12 often causes interference from many factors such as dust or water vapor; Oxidation occurs, which affects the transmission quality of the connector, which is really not a good connector design.

Utility model content

The purpose of the utility model is to provide an insulating back plug of a connector to overcome the defects of the known technology.

In order to achieve the above purpose, the insulating back plug of the connector provided by the utility model includes a connector body, and a plurality of metal contacts are arranged at the front end of the connector body; and

An insulating back plug is in the shape of an inverted T. Two rows of corresponding saw-toothed grooves are arranged on the upper part of the insulating back plug, and a hollow part is arranged on the bottom of the insulating back plug. The plurality of metal contacts are socketed on the insulating back plug. The bottom is hollowed out so that the plurality of metal contacts are exposed in the zigzag groove.

The insulating back plug of the connector, wherein the material of the insulating back plug is hard nylon material.

The insulating back plug of the connector, wherein the insulating back plug can be arranged on the connector of the iPod connector.

In the insulating back plug of the connector, the length of the jagged groove is about 0.55 mm, and the width is about 0.3 mm.

The insulating back plug of the connector, wherein the length of the insulating back plug is about 17 mm, and the width is about 1.3 mm.

The insulating back plug of the connector, wherein the upper part of the insulating back plug is about 1.8 mm high.

The insulating back plug of the connector, wherein the height of the bottom of the insulating back plug is about 1.2 mm.

In the insulating back plug of the connector, the hollow part is arranged opposite to the saw-toothed groove.

According to the implementation of the utility model, the metal contact is arranged in the zigzag groove, so that the metal contact and the metal contact will not interfere with each other through the insulating back plug, and the transmission quality of the connector is further improved. Wherein the insulating back plug can be used on the iPod connector, and has the effects of dustproof, anti-interference and better insulation.

Detailed ways

In order to facilitate and succinctly understand other features and advantages of the utility model and the effects achieved by it can be more apparent, the utility model will be described in detail as follows in conjunction with the accompanying drawings:

Please refer to FIG. 2 which is a perspective view of the insulating rear plug of the utility model connector and FIG. 3 which is a perspective exploded view of the insulating rear plug of the utility model connector. As shown in the figure, a connector body 16 is located at the front end of the connector body 16 A plurality of metal contacts 18 are provided, and the metal contacts 18 are responsible for connecting with another connector for signal transmission, but the problem often lies in the fact that the metal contacts 18 do not have effective protection devices, resulting in the connector joints being easily damaged. Therefore, we set an insulating back plug 20 in an inverted T shape on the metal contact 18. The insulating back plug 20 is divided into an insulating back plug upper part 201 and an insulating back plug bottom part 202, wherein the insulating back plug upper part 201 Two rows of saw-toothed grooves 203 are provided, and a hollow part 204 is provided on the bottom 202 of the insulating back plug, and the two rows of saw-toothed grooves 203 are set correspondingly to the hollowed part 204. When a plurality of metal contacts 18 are socketed on When the insulating back plug is in the hollow portion 204 of the bottom 202 , the plurality of metal contacts 18 are just exposed in the serrated groove 203 .

Please refer again to Fig. 3, which is a three-dimensional exploded view of the insulating rear plug of the utility model connector, Fig. 4, which is an embodiment diagram of the insulating rear plug of the utility model connector, and Fig. 5, which is a top view of the insulating rear plug of the utility model connector, such as As shown in the figure, the length of the serrated groove 203 is about 0.55 mm, and the width is about 0.3 mm. The length of the insulating back plug 20 is about 17 mm, and the width is about 1.3 mm. In addition, the height of the upper part 201 of the insulating back plug is about 1.8 mm. , the bottom 202 of the insulating back plug is about 1.2 mm high, and can be arranged on the iPod connector joint or the metal contact 18 of various connectors; and the metal contact 18 and the metal contact 18 will not interfere with each other through the insulating back plug 20 , the signal will be transmitted more clearly; because the bottom 202 of the insulating back plug covers the metal contact 18, the external dust or moisture is not easy to cause damage to the metal contact 18, and the material of the insulating back plug 20 is hard Nylon material with low manufacturing cost is suitable for mass production and can be applied to various connectors.

The above-described embodiments are only to illustrate the technical ideas and characteristics of the present utility model, and its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly.
