Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

A certain gap exists between a connector body and a shell of the USB connector, which seriously affects the air tightness of the connector, and the gap between the connector body and the shell of the USB connector is generally sealed by using a dispensing method at present so as to achieve the aim of water resistance of a product; however, since the liquid resin used for dispensing has certain fluidity and viscosity, the resin is easy to creep, which seriously affects the electrical performance and reliability of the connector.

In order to solve the above problems, in this embodiment, a sealing element may be disposed at the first end of the tongue plate of the connector body, and when the housing and the connector body are pressed and fixed, the sealing element is pressed to tightly seal a gap between the housing and the first end of the tongue plate of the connector body, so that poor electrical performance caused by glue climbing due to glue dispensing may be avoided, and a waterproof effect is achieved.

Fig. 1 is a sectional view of a USB connector according to an exemplary embodiment, where, as shown in fig. 1, the connector 1 includes a connector body 11, and the connector body 11 includes a fixing portion 110 and a tongue plate 111 protruding from the fixing portion 110; the tongue plate 111 includes a first end 111A adjacent to the fixing portion 110, and a second end 111B opposite to the first end 111A; as shown in fig. 1, the tongue plate 111 is a plate-shaped structure extending from a middle position of the fixing portion 110, and the tongue plate 111 can be inserted into a port of a corresponding terminal to connect the corresponding terminal. A seal 12, said seal 12 being arranged at a first end 111A of said tongue plate 111; and a housing 13 press-fitted and fixed to the outside of the connector body 11, wherein the sealing member 12 tightly seals a gap between the housing 13 and the first end 111A of the tongue plate 111, which completes sealing of the gap between the connector body 11 and the housing 13.

For example, fig. 2 is a schematic structural diagram of a USB Type-C connector according to an exemplary embodiment, as shown in fig. 2, in order to facilitate the assembly of the housing 13 and the connector body 11, an inner space of the housing 13 is slightly larger than that of the connector body 11, so that as shown in fig. 2, the housing 13 and the connector body 11 are provided with a sealing member 12 at a first end of a tongue plate 111 of the connector body 11, as shown in fig. 2, so that the housing 13 and the connector body 11 form an interference when combined, and the sealing member 12 can seal a gap between the connector body 11 and the housing 13, thereby avoiding the influence on the reliability of the electrical performance when the glue is not applied, and achieving the waterproof effect of the product.

Here, the connector body may also be referred to as a female end of the connector, and the female end may be formed by injection molding and may also be referred to as an injection molded female end.

In the embodiment, the sealing element can be arranged at the first end of the tongue plate of the connector body, when the shell and the connector body are pressed and fixed, the sealing element can tightly seal a gap between the shell and the first end of the tongue plate of the connector body under the action of pressure, so that the electric performance defect caused by glue climbing possibly caused by dispensing can be avoided, and the waterproof effect is achieved.

In a possible embodiment, the seal comprises a ring-shaped seal surrounding the first end of the flap.

In one possible embodiment, the seal comprises a silicone ring.

Here, the sealing member 12 may be an elastic and deformable sealing member such as a rubber ring, so that interference may be formed when the housing 13 and the connector body 11 are combined, due to the elasticity of the sealing member 12 and the characteristic that the sealing member is deformed by pressure, the housing 13 and the connector body 11 may be pressed and fixed under an allowable pressure, and the sealing member 12 may seal a gap between the first end of the tongue plate 111 of the connector body 11 and the housing 13, thereby achieving a waterproof effect of a product when the reliability of electrical performance is not affected by poor dispensing.

The sealing element can be a silicon rubber ring, the toughness and the elasticity of the silicon rubber are good, and the gap between the shell and the connector body can be well sealed.

In one possible embodiment, the housing comprises a metal shell.

Here, the metal shell can play a role in shielding, and can eliminate electromagnetic interference of the outside to the connector. Illustratively, the metal shell may be an iron shell or the like.

In a possible implementation manner, the housing includes a first shielding shell and a second shielding shell, the first shielding shell and the connector body are fixed in a pressing manner, and the second shielding shell is sleeved outside the first shielding shell.
