Description

a plug

technical field

The utility model relates to a plug, in particular to a plug provided with a plurality of metal contact parts.

Background technique

In electronic products, such as mobile phones, MP3, MP4 or handheld computers, there are audio or video jacks for connecting audio or video plugs. Traditional plugs generally only have a cylindrical plug, which will be connected to audio or video plugs. The metal contacts of the video lines are integrated on the circumference of the cylinder. Since the trend tends to be small and beautiful electronic products, the volume of the plug will not be large, and many metal contact parts cannot be integrated, which cannot meet the needs of product development.

Utility model content

The purpose of the utility model is to provide a plug with a simple structure and a plurality of metal contact parts on the plug, so that more types of data or power input and output can be connected.

The technical scheme that the utility model adopts for realizing the above object is:

A plug, which includes a cylindrical insulating base body, the outer periphery of the insulating base body is provided with a number of mutually isolated metal contact parts, the tail of the insulating base body is provided with a metal contact head, and the metal contact head is arranged on a The metal pins at the center of the insulating matrix are connected.

As a further improvement of the utility model, there are three metal contact parts, namely the first metal contact part, the second metal contact part and the third metal contact part, and the second and third metal contact parts are stepped A metal pipe, the first metal contact part is a metal pipe, the first, second and third metal contact parts are sequentially arranged on the outer periphery of the insulating base from top to bottom, and the three metal contact parts The connecting ends are respectively arranged at the head of the insulating base.

As a further improvement of the present invention, the middle ring of the first metal contact part is provided with a protrusion to strengthen its positioning in the insulating matrix.

As a further improvement of the present invention, the steps of the second and third metal contact parts are rounded corners produced by drawing process, and the rounded corners are not directly processed by lathe in the traditional processing method.

As a further improvement of the utility model, the head of the metal contact is provided with an annular protrusion to strengthen its connection with the insulating base.

As a further improvement of the utility model, the head of the metal needle protrudes from the head of the insulating base.

The beneficial effects of the utility model are: the utility model has a simple structure, a plurality of metal contact parts are arranged on the insulating base, the volume is small, and it is convenient to carry and use, so that more kinds of data or power output and input can be connected.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

Detailed ways

Embodiment: see Fig. 1 and Fig. 2, a kind of plug of the present utility model, it comprises a cylindrical insulating matrix 4, and the outer periphery of described insulating matrix 4 is provided with a plurality of mutually isolated metal contact parts, and described insulating matrix 4 A metal contact head 5 is provided at the tail of the body, and the metal contact head 5 is connected with a metal pin 6 arranged in the center of the insulating base 4 . There are three metal contact parts, namely the first metal contact part 1, the second metal contact part 2 and the third metal contact part 3, and the second and third metal contact parts 2 and 3 are stepped metal tubes , the first metal contact part 1 is a metal tube, and the first, second and third metal contact parts 1, 2 and 3 are sequentially arranged on the outer periphery of the insulating base 4 from top to bottom, and the three The connecting ends 11, 21, 31 of the metal contact parts 1, 2, 3 are respectively arranged on the head of the insulating base 4. The middle ring of the first metal contact part 1 is provided with a protrusion 12 to strengthen its positioning in the insulating base 4 . The steps 22, 32 of the second and third metal contact parts 2, 3 are rounded corners generated by the drawing process. In the existing technology, the rounded corners are directly processed by a lathe, but the patented The rounded corners mentioned above are generated by the drawing process, which reduces the production cost. The head of the metal contact 5 is provided with an annular protrusion 51 to strengthen its connection with the insulating base 4 . The head of the metal needle 6 protrudes from the head of the insulating base 4 .

As described in the embodiment of the utility model, other plugs with the same or similar structure as the utility model are all within the protection scope of the utility model.
