Description

waterproof connector

technical field

The utility model relates to a connector, in particular to a waterproof connector.

Background technique

Connectors have been widely used in the computer industry and home video and audio equipment. Users can quickly transmit the required data or signals through the connector, and now there is an image display connector with a transmission data bandwidth of 10.8Gbps. The emergence of connectors speeds up the speed of information reception and makes people's lives more convenient.

As shown in Figure 1, it is a schematic diagram of the production of a known connector. The structure of a general connector includes an insulating base a, a conductive terminal group b, a covering body c, and a transmission line d, wherein the conductive terminal group b is passed through and fixed on the Inside the insulating base a, the transmission line d is connected to one end of the conductive terminal group b, and then the connection between the conductive terminal group b and the transmission line d is covered by the covering body c for insulation. However, this construction has the following disadvantages:

1. Since the covering body c is injection molded to cover the conductive terminal group b and the transmission line d, the plastic of the covering body c is easy to hit the connection between the conductive terminal group b and the transmission line d when it is injected, and Poor contact or breakage of solder joints may result, resulting in reduced production yield.

2. Since the insulating base a is a hard material, and the covering body c is a soft material, the two materials are closely attached to each other, but after a period of use, the two materials are too different in physical properties, so the two materials The gaps between the two materials will slowly form and peel off, causing moisture to infiltrate, making the conductive terminal group damp and reducing its efficacy.

In view of the above-mentioned first shortcoming, another known connector structure has been developed, as shown in FIG. In the space a2, the welding place between the conductive terminal group b and the transmission line d is formed inside the accommodating space a2, and the function of the connecting section a1 is to protect the welding place between the conductive terminal group b and the transmission line d, so that the connector is in the covering body When c is injection molding, the plastic of the covering body c will not directly hit the welding place, causing damage to the conductive terminal group b and the transmission line d, but this method has the following disadvantages:

1. Since the welding place between the conductive terminal group b and the transmission line d is formed inside the accommodating space a2, when the conductive terminal group b and the transmission line d are to be welded in the manufacturing process, the welding is difficult due to the narrow working space Process yield decreases.

2. Following the first point, if the yield rate of the welding process is to be improved, the length of the conductive terminal group b must be lengthened so that the conductive terminal group b protrudes from the connection section a1, but the too long conductive terminal group b is easily affected. Bending and breaking damage.

Therefore, how to improve the production yield of the connector, how to make the connector waterproof, and how to improve the overall structural strength of the connector have become the subjects studied by the inventors of the present invention.

Except that the hollow cylinder 30 and the connecting section 11 can be connected in a locked manner, the inside of the connecting section 11 (ie, the accommodating groove) 12) can be formed with a fixing groove 112, the hollow cylinder 30 penetrates the fixing groove 112 in a piercing manner, so that the hollow cylinder 30 and the connecting section 11 are connected to each other, and the inner wall of the fixing groove 112 can be coated Cloth waterproof glue to strengthen the waterproof function. This way can save the cost of processing threads on the hollow cylinder 30 and the connecting section 11, and can also reduce production costs. In addition, the outer surface of the connecting section is formed with external threads 111. The outer surface of the hollow cylinder 30 is formed with tooth marks 33, and the external thread 111 and the tooth marks 33 are used to improve the ability of the covering body 40 to bite on the hollow cylinder 30 and the insulating seat 10, so that it is not easy to fall off, and it can also Strengthen waterproof ability.

Please refer to Figure 11, which is a schematic diagram of the production of the present invention. When the waterproof connector of the present invention covers the covering body 40, the insulating base 10 and the conductive terminal group are firstly formed by injection molding. 20. The hollow cylinder 30 and the electric wire 60 are placed in the mold 70, and there is a mold cavity 71 inside the mold 70.
