Description

Waterproof connector structure

Technical Field

The present invention relates to an electrical connector, and more particularly to a waterproof connector structure.

Background

Accordingly, due to the improvement of waterproof requirements of electronic products, the electrical connector applied to the related electronic products becomes one of the most important roles in waterproof effect. It is obvious that if the electrical connector cannot achieve the waterproof function, the electronic product cannot pass the waterproof test immediately.

In the conventional electrical connector, a waterproof ring made of a rubber material or a waterproof structure formed by solidifying a waterproof adhesive is mainly used as a waterproof structure. A common waterproof ring is used for the joint of two objects, and waterproof glue is usually used for filling a gap or further blocking the rear end of the connector to achieve the sealing effect; however, in the waterproof design of the connector, if only the waterproof ring is arranged, the waterproof effect is not always improved enough, so that the waterproof effect provided by the solidified waterproof glue is common.

However, if the waterproof glue is used as a waterproof means, it is necessary to seal the part to be waterproof by injecting the waterproof glue after all the components of the connector are assembled, so that the choice of where the connector is outside as an injection port affects the flow of product assembly and the quality of waterproof performance.

In view of the above, the present invention is directed to overcoming the above-mentioned disadvantages, and is especially directed to a novel and effective solution for overcoming the above-mentioned disadvantages.

Detailed Description

In order to further disclose the features and technical contents of the present invention, please refer to the following detailed description and accompanying drawings, which are provided for reference and illustration purposes only and are not intended to limit the present invention.

Please refer to fig. 1 and fig. 2, which are an exploded view and an assembled view of the present invention before glue injection. The utility model provides a waterproof connector structure, which comprises a connecting body 1, a metal shell 2 and a waterproof component 3 (shown in figure 4); wherein:

the connector body 1 has a base 10, a tongue 11 extending forward from the base 10, and a plurality of terminals 12; in more detail, each terminal 12 has a contact end 120 and a soldering end 121 extending from the contact end 120 and integrally connected with the contact end 120, wherein the contact end 120 is exposed or protruded on the upper surface or the lower surface of the tongue 11, respectively, and each terminal 12 passes through the base 10 and extends backward such that each soldering end 121 extends out of the rear end of the base 10. In the illustrated embodiment of the present invention, the arrangement and combination of the terminals 12 conform to the USB Type-C specification.

As shown in fig. 3, the metal shell 2 is installed outside the connecting body 1 to cover the base 10 of the connecting body 1 and extend to the tongue 11 to form a socket 210; more specifically, the present invention provides that the metal shell 2 includes an outer shell 20 and an inner shell 21, and the inner shell 21 is disposed in the front end of the outer shell 20 and located at the tongue 11 to form the socket 210 for plugging a mating connector (not shown).

Referring to fig. 1 and 3, the present invention mainly includes a surrounding waterproof groove 100 disposed on the connecting body 1; specifically, the waterproof groove 100 may be formed in the base 10 of the connector body 1 or may be interposed between the base 10 and the tongue 11 of the connector body 1. Furthermore, as shown in fig. 3, the waterproof groove 100 may be disposed such that the middle portion of each terminal 12 in the connection body 1 is exposed, and a glue injection port 101 is disposed at the rear end of the base 10, wherein the glue injection port 101 extends toward the waterproof groove 100 and is communicated with the waterproof groove. As shown in fig. 1, the portion of the glue injection port 101 connected to the waterproof groove 100 may be formed by a concave surface of the base 10, and then the metal casing 2 covers the concave surface to form a channel for injecting a functional glue such as waterproof glue, as shown in fig. 3; meanwhile, an opening 200 corresponding to the glue injection opening 101 is also formed on the metal shell 2. In the illustrated embodiment, the opening 200 is located at the rear end of the outer shell 20 of the metal shell 2. In addition, as shown in fig. 1, the glue injection opening 101 may be gradually enlarged near the waterproof slot 100.

Accordingly, as shown in fig. 3, after the connecting body 1 and the metal shell 2 are assembled, the opening 200 of the metal shell 2 is filled with the waterproof glue (not shown) for forming the waterproof member 3, so that the waterproof glue is fully filled in the waterproof groove 100, and even in the glue injection opening 101. Since the waterproof groove 100 and the glue injection opening 101 are already covered by the metal shell 2, the waterproof glue can be solidified into the first waterproof portion 30 in the waterproof groove 100 and the second waterproof portion 31 in the glue injection opening 101, and both can be tightly attached to the inner wall of the metal shell 2, so as to achieve the waterproof effect between the connecting body 1 and the metal shell 2, and meanwhile, the waterproof groove and the glue injection opening 101 can be dustproof and have improved tightness. In addition, the second waterproof portion 31 is substantially integrally formed with the first waterproof portion 30, depending on whether the amount of the injected waterproof glue overflows to the glue injection port 101; of course, it is preferable to fill the waterproof groove 100 and the glue injection opening 101 with waterproof glue to reduce the influence of bubbles on the waterproof property.

Referring to fig. 1 to 4, the metal shell 2 may further be sleeved with a waterproof ring 4 at the front end, and the waterproof ring 4 may be made of rubber or other materials; in the illustrated embodiment of the present invention, the waterproof ring 4 is located between the front end of the inner shell 21 and the front edge of the outer shell 20 of the metal shell 2, as shown in fig. 3 or 4.

Therefore, the waterproof connector structure of the utility model can be obtained by the above structure.

However, the above description is only a preferred practical embodiment of the present invention, and not the scope of the present invention, so that the equivalent structural changes of the present invention can be found in the specification and drawings of the present invention.

Of course, the present invention can have other embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the claims of the present invention.
