Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, and more specifically to a connector rubber-coated sealing ring. Background Art

[0002] Connectors are widely used in electrical equipment such as automobiles and home appliances. Electric power or signal transmission can be achieved through connectors. General connectors are easily exposed to humid external environments. Water vapor in the external environment can easily penetrate into the interior of the connector through the gap between the connector outer shell and the inner shell. In order to solve the problem of water seepage in the connector, the current conventional solution is to set a sealing ring between the outer shell and the inner shell of the connecting line to make it waterproof. Most of the sealing rings are set between the end of the inner shell of the connector and the outer shell. Usually, a cover plate is installed at one end of the outer shell to limit the axial movement of the sealing ring.

[0003] For example, a waterproof connector socket disclosed in utility model patent publication number CN220021675U includes a seat body, a conductor is arranged in the seat body, a plastic part for mounting the conductor is fixed in the seat body, a sealing ring is lined between the outer wall of the plastic part and the inner wall of the seat body, and a cover plate is provided at the rear end of the seat body to achieve sealing. The sealing ring needs a cover plate to limit its axial movement, and the sealing ring is not fixedly connected to the outer wall of the plastic part and the inner wall of the seat body. Long-term use will cause the sealing ring to age and deform, and it is easy to shake inside the seat body, thereby causing sealing failure. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please refer to Figure 1 The embodiment of the utility model provides a connector rubber-encapsulated sealing ring, including a connector housing 1 and a sealing ring 2. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the outer wall of the upper end of the connector housing 1 can be formed with an edge boss 11, and a connecting protrusion 12 is formed on the edge boss 11. The sealing ring 2 is sleeved on the outer wall of the connecting protrusion 12. The outer edge of the sealing ring 2 is provided with at least two side sealing ribs 21 for achieving a sealed connection with the inner wall of the connector housing by interference fit. The inner wall of the sealing ring 2 is fixedly connected to the outer wall surface of the connecting protrusion 12, and the bottom surface of the sealing ring 2 is fixedly connected to the top surface of the edge boss 11. The top surface of the sealing ring 2 is in the same plane as the top surface of the connecting protrusion 12. Among them, the connector housing 1 can be set to a plastic material.

[0024] Specifically, each side sealing rib 21 can be arranged at intervals along the axial direction of the sealing ring 2 .

[0025] The sealing ring 2 can be preferably configured as a silicone sealing ring. Silicone has a good moisture absorption effect, can absorb water vapor in the environment, and play an insulating role, and has high reliability in a humid environment. In other embodiments, the sealing ring 2 can also be made of other elastic materials in one piece, which can reduce the number of parts and save assembly steps.

[0026] In this embodiment, the inner wall of the sealing ring 2 can be bonded to the outer wall of the connecting protrusion 12 by means of overmolding to achieve a fixed connection.

[0027] Furthermore, the bottom surface of the sealing ring 2 can be bonded to the top surface of the edge boss 11 by overmolding to achieve a fixed connection.

[0028] During implementation, this embodiment adopts the overmolding process, and by injecting the rubber into the gap between the sealing ring 2 and the outer wall surface of the connecting protrusion 12 and the top surface of the edge boss 11, the rubber is fully contacted between the inner wall and the bottom of the sealing ring 2 and the corresponding connecting parts on the connector housing 1, thereby improving the adhesion strength and having an anti-infiltration function, and can prevent the sealing ring 2 from falling off when mating with the connector housing and causing sealing failure. Among them, the rubber can be glue made of methyl silicone monomer or methyl silicone mixture.

[0029] In specific implementation, when the rubber-coated sealing ring is paired with the corresponding connector housing, the sealing ring 2 will not be flanging. The sealing ring 2 with the side sealing rib 21 can be interference fit with the inner wall of the matching connector housing, and can always maintain a contact state to achieve sealing. It has the function of sealing, waterproofing and anti-seepage, and ensures the sealing between the two.

[0030] Preferably, the shape of the connector housing 1 can be set to be square, and the four corners of the outer edges of the connector housing 1 and the sealing ring 2 are all set with rounded corners. Such a design can facilitate demoulding of the connector housing 1 and the sealing ring 2 after molding during manufacturing.

[0031] Preferably, the connector housing 1 may be provided with a plurality of terminal insertion holes 13 extending from the top surface to the bottom surface thereof.

[0032] In order to facilitate the insertion of the connector terminal, the opening edge of the insertion end of each terminal insertion hole 13 can be provided with a plug-in guide portion 14, which is arranged in an arc-shaped structure and can play a guiding role.

[0033] To sum up, the utility model arranges the sealing ring on the outer wall of the connecting protrusion of the connector shell and fixedly connects it to the connecting protrusion. Compared with the traditional connector which needs to assemble a cover plate on the top of the sealing ring to limit the axial movement of the sealing ring, the utility model does not need to install parts such as a cover plate, and has the functions of sealing, waterproofing and anti-seepage. At the same time, the sealing ring will not be flanging during the mating process with the connector shell. The structure is compact and will not fall off, so it can be used in occasions where the sealing space is relatively compact.

[0034] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
