Detailed Description

The following further description is made with reference to the drawings and specific embodiments.

As shown in fig. 1 and 2, the present embodiment provides a USB male connector 100 that can be directly plugged into a mating female connector. The USB male connector 100 is composed of a conductive terminal 10, a plastic body 20 and an insulating housing 30, wherein the conductive terminal 10 has a double-layer structure, and is molded in the plastic body 20 by a plastic-coating process and is formed in one step. The front end of the conductive terminal 10 has a front terminal 11 and a back terminal 12, and the front terminal 11 and the back terminal 12 have the same structure and are respectively used for inserting the female terminal from the front and inserting the female terminal from the back to form an electrical connection with the terminals in the female terminal. Therefore, after the injection molding is completed, the front terminals 11 and the back terminals 12 are exposed and cannot be covered or blocked by the plastic body 20.

The insulating housing 30 of the present embodiment can be made of an insulating material such as plastic or rubber, and is wrapped around the plastic body 20 and the conductive terminal 10, and a plurality of hollow portions 31 are disposed on the front and back sides of the housing and respectively correspond to the front terminals 11 and the back terminals 12, so that the front terminals 11 and the back terminals 12 are respectively exposed out of the hollow portions 31, so as to be electrically connected to the terminals in the female terminal.

Specifically, the front terminals 11 and the back terminals 12 are four, two of the front terminals 11 and the back terminals 12 are provided with first gold fingers 111, the other two are provided with second gold fingers 112, the two front terminals 11 or the back terminals 12 with the first gold fingers 111 are located in the middle, and the two front terminals 11 or the back terminals 12 with the second gold fingers 112 are located on two sides. The two second gold fingers 112 are of a dual-contact structure, and specifically, both of the two second gold fingers are of a dual-contact structure composed of two convex hulls protruding outwards. The double-contact structure can improve the connection reliability with the inner terminal of the female head and prevent the phenomenon of poor contact.

In this embodiment, the rear end of the conductive terminal 10 is connected to an adapter plate 40, the front and back surfaces of the adapter plate 40 are respectively provided with a power line VBUS, a ground line GND and data lines D + and D-, the front terminal 11 is connected to the power line, the ground line and the data line on the front surface of the adapter plate 40, and the back terminal 12 is connected to the power line, the ground line and the data line on the back surface of the adapter plate 40. The power lines, the ground lines and the data lines on the front and the back of the adapter plate 40 are arranged in the same order, so that the adapter plate can be normally used when being inserted into a female head from the front and the back. Taking the front terminal 11 as an example, the front terminal 11 where the two first gold fingers 111 are located is connected to the data line D + and D-, and the front terminal 11 where the two second gold fingers 112 are located is connected to the power line VBUS and the ground line GND, respectively. The reverse terminals 12 are connected in a similar manner.

Referring to fig. 3 and 4, the front terminals 11 and the back terminals 12 of the present embodiment are arranged in parallel and separated from each other by a plurality of plastic spacers 13 to realize insulation. After the relative positions of the front terminals 11 and the back terminals 12 are fixed, the plastic body 20 can be obtained by placing the plastic body into an injection molding machine for injection molding.

In summary, the conductive terminal of the double-layer structure is wrapped in the plastic body, the outer side of the plastic body is wrapped with the insulating shell, and meanwhile, the plurality of hollow parts are arranged corresponding to the front terminal and the back terminal, so that the front terminal and the back terminal are exposed out of the hollow parts, the USB male connector has the function of a double-sided plug, the front side and the back side do not need to be distinguished when the USB male connector is used, and the conductive terminal is directly wrapped in the plastic body, so that the structure of a product is exquisite. The structure of the circuit board commonly adopted in the traditional USB male connector is avoided, so that a complex welding procedure is omitted, the production efficiency and the yield of products can be effectively improved, and the production cost of the products can be remarkably reduced.
