Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a non-slip and non-detachable waterproof connector. Background Technology

[0002] A waterproof connector is a functional connector specifically designed for use in humid, wet, or high-humidity environments. It effectively prevents liquids (such as water) from entering the internal circuitry or terminals, ensuring stable electrical connections and equipment safety. Its core feature is achieving reliable waterproof performance through special structural design and material selection, while maintaining the conductivity of the electrical connection. Waterproof connectors primarily address the problems of insulation failure, short circuits, and corrosion experienced by traditional connectors in humid, water-rich environments, ensuring the continuity and reliability of signal or power transmission. For example, in scenarios such as outdoor rain, underwater operations, or damp workshops, ordinary connectors may suffer from poor contact or equipment damage due to water ingress, while waterproof connectors avoid such risks.

[0003] The main structure of current waterproof connectors includes an insulating body, terminals, and a shielding shell. The insulating body includes a base and a tongue plate extending forward from the base. The terminal is embedded and fixed on the insulating body. The terminal has a contact portion and a solder portion. The contact portion protrudes from the surface of the tongue plate, and the solder portion protrudes from the base and is soldered to the wire for conduction. The shielding shell covers the outside of the insulating body.

[0004] In existing technologies, to achieve waterproofing, a seamless, stretched-molded shielding shell is used, with adhesive applied to the rear end of the insulating body. A waterproof ring is also placed at the front end of the shielding shell. This type of waterproof connector, requiring a stretched-molded shielding shell and adhesive application, is cumbersome and costly to manufacture. Furthermore, the single waterproof ring provides poor waterproofing and fails to meet usage requirements. In addition, this type of connector lacks anti-slip and anti-detachment structures, hindering quick and secure installation of the device shell and making the connector prone to detachment, thus compromising continuous waterproofing. Therefore, it is necessary to improve current waterproof connectors. Utility Model Content

The groove 31 is annular and surrounds the outer peripheral side of the plastic shell 30. In this embodiment, the rear end of the insulating body 11 is embedded and fixed together with the plastic shell 30. The inner bottom surface of the groove 31 has multiple protrusions 301, which are elongated structures extending left and right. There are four protrusions 301, located on the upper and lower inner bottom surfaces of the groove 31, respectively. The anti-disengagement part 32 is an arc-shaped protrusion, and two arc-shaped protrusions 32 are symmetrically arranged on the left and right sides. The anti-slip part 33 includes a rib 331 and a recess 332 for inserting fingers. The rib 331 is arc-shaped and is arranged around the outer periphery of the plastic shell 30. There are multiple ribs 331 arranged at intervals. There are two recesses 332, which are located at the center of the upper and lower surfaces of the rear end of the plastic shell 30, respectively, so as to achieve a good anti-slip effect. In addition, the recess 332 is a circular recess to better allow fingers to be inserted and positioned, and the anti-slip effect is better.

[0041] The front waterproof ring 40 is sleeved on the outer peripheral side of the front end of the connector body 10 and located on the front side of the plastic shell 30.

Next, the shielding shell 13 is covered over the insulating body 11, thus forming the connector body 10. Then, the front end of the wire 20 is welded to the soldering part 122. Next, the connector body 10 and the wire 20 are placed in another injection mold and a plastic shell 30 is formed, so that the plastic shell 30 covers the connector body 10 to form a semi-finished product. Then, the semi-finished product is placed in another mold to form a front waterproof ring 40 and a rear waterproof ring 50 on the plastic shell 30.

[0045] This product is typically plugged into a connector installed in the socket of the equipment housing. When in use, hold the anti-slip part 33 to plug it in. After plugging in, the front waterproof ring 40 and the rear waterproof ring 50 are tightly fitted with the inner wall of the socket, achieving double waterproof plugging and excellent waterproof effect. At the same time, the anti-detachment part 32 is fastened to the equipment housing to prevent the product from easily coming out of the socket, providing strong protection for continuous waterproofing.

[0046] The key design feature of this invention is that by injection molding a plastic shell to cover the connector body, with the plastic shell covering the outer periphery and rear end face of the connector body, there is no need to use a stretch-formed seamless shell as a shielding shell, nor is there a need for adhesive application. This simplifies the production process and reduces production costs. Furthermore, the use of front and rear waterproof rings provides double waterproofing, effectively enhancing the waterproofing performance and meeting usage requirements. Additionally, the inclusion of anti-detachment and anti-slip features on the plastic shell allows for quick and secure installation to the device housing, preventing the product from easily detaching from the connector hole and providing strong protection for continuous waterproofing. This makes the product more convenient to use.

[0047] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
