Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a USB Type-C female connector that can be used underwater with electricity. Background Technology

[0002] USB Type-C female connectors, also known as Type-C female connectors or C-type USB female connectors, are a new type of USB interface. Compared with traditional USB interfaces (such as Type-A and Type-B), Type-C interfaces have significant differences in physical form and offer many technological advantages. The Type-C interface design allows for reversible insertion, greatly improving user convenience and reducing the hassle of incorrect insertion. Type-C interfaces support the USB 3.1 standard, achieving data transfer speeds of up to 10Gbps, far exceeding the speeds of traditional USB interfaces. Type-C female connectors are widely used in various devices requiring high-speed data transfer, high-power charging, or audio / video transmission. For example, in the smartphone industry, an increasing number of high-end models are adopting Type-C interfaces; in the laptop industry, Type-C interfaces are gradually becoming one of the mainstream interfaces.

[0003] Currently, the main structure of a USB Type-C female connector typically consists of an insulating body, a terminal block, and a housing. To achieve waterproofing, a waterproof ring is usually assembled or injection molded from liquid silicone at the head of the housing. The waterproof ring fits tightly with the inside of the connector on the device housing to ensure that water cannot enter around it. At the same time, adhesive is applied to a groove at a certain location on the insulating body to prevent water from entering the insertion cavity and then seeping through the tail of the insulating body to corrode the PCB board inside the device.

[0004] However, according to the dimensions specified by the USB Association, even after the male connector is inserted into the insertion cavity at the front of the female connector, there is still a theoretical gap between the inner wall of the insertion cavity and the outer wall of the male connector, as follows: Male connector outer dimensions: 8.25±0.03mm, 2.40±0.03mm; Insertion cavity dimensions: 8.34±0.04mm, 2.56±0.04mm. This means that water can still enter the insertion cavity after the male connector is inserted. Furthermore, operating a powered device with the male connector inserted into a water-filled female connector poses a risk of short circuits and damage due to water being a conductor. Additionally, the exposed head of the connector is easily damaged by impacts. Therefore, it is necessary to improve the current USB Type-C female connector. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a USB Type-C female connector that can be used underwater with electricity. This effectively solves the problems of existing USB Type-C waterproof female connectors, such as the easy ingress of water into the insertion cavity leading to various hidden dangers, and the easy damage to the shell head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A USB Type-C female connector for underwater use with live power includes an insulating body, a terminal group, and a housing. The insulating body includes a base and a tongue extending from the base. The terminal group is disposed on the insulating body. The housing covers the insulating body, and the inner wall surface of the housing is a closed surface. An insertion cavity for inserting a male connector is formed between the inner wall surface of the housing and the outer wall surface of the tongue. A retaining ring extends outward from the front edge of the housing. A waterproof rubber ring is integrally injection molded at the front end of the housing. The waterproof rubber ring includes an outer sealing ring, a covering ring, and an inner sealing ring integrally connected in sequence. The outer sealing ring is located behind the retaining ring, the covering ring completely covers the retaining ring, and the inner sealing ring is located inside the opening of the insertion cavity.

[0008] As a preferred embodiment, the outer sealing ring has a raised crest that protrudes from the outer peripheral side of the retaining ring, and the rear side of the outer sealing ring is a vertical surface to achieve better waterproofing.

[0009] As a preferred embodiment, the outer surface of the inner sealing ring has an arc-shaped protrusion structure, which includes an inlet surface, a contact surface, and a support surface connected sequentially from front to back, so as to form a better waterproof sealing structure with the outer wall of the male head.

[0010] As a preferred embodiment, the front side of the covering ring is an upright surface, and the outer edge of the covering ring forms a guide slope. The guide slope extends obliquely to the rear and outward so as to mate with the insertion interface of the equipment housing, thereby avoiding damage to the waterproof rubber ring during the insertion and installation process, and thus helping to ensure the waterproof effect.

[0011] As a preferred embodiment, the housing includes an inner shell and an outer shell, the inner shell covering the insulating body, the insertion cavity located in the inner shell, the retaining ring located at the front end of the inner shell, and the outer shell covering the outer shell.

[0012] As a preferred option, the inner shell is a seamless stretched metal shell for better waterproofing.

[0013] As a preferred embodiment, the housing is a stamped metal shell for external mounting and securing.

[0014] As a preferred embodiment, the USB Type-C female connector that can be used underwater with electricity is a board-mounted, recessed, vertical, or horizontal USB Type-C female connector.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] By designing the waterproof rubber ring as an integrally formed structure consisting of an outer sealing ring, a covering ring, and an inner sealing ring, the outer sealing ring seals against the external device housing, while the inner sealing ring seals against the outer wall of the male connector. This effectively prevents water from entering the insertion cavity, achieving multiple layers of waterproofing for complete protection. After the male connector is inserted into the insertion cavity, it can be used underwater while powered without the risk of short circuits or damage due to water ingress, thus providing convenience for users. Furthermore, the covering ring completely covers the retaining ring, preventing the front end of the housing from being exposed and better protecting the housing from scratches and damage, thereby extending the product's lifespan.

[0035] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a terminal group 20, and a housing 30.

[0036] The insulating body 10 includes a base 11 and a tongue plate 12 extending from the base 11. In this embodiment, the insulating body 10 is made of one-piece plastic material. The base 11 has a glue groove 101, which is filled with glue to form a seal (not shown in the figure).

[0037] The terminal group 20 is disposed on the insulating body 10; the terminal group 20 is inserted into the dispensing groove 101 and fixed together with the sealing element; the terminal group 20 has multiple contact portions 21 and multiple welding portions 22; the multiple contact portions 21 are exposed on the two surfaces of the tongue plate 12 respectively; the multiple welding portions 22 extend out of the base 11.

[0038] The housing 30 covers the insulating body 10. The inner wall of the housing 30 is a closed surface. An insertion cavity 301 for inserting the male head 40 is formed between the inner wall of the housing 30 and the outer wall of the tongue plate 12. The front edge of the housing 30 is bent outward to extend a retaining ring 302. The front end of the housing 30 is integrally injection molded with a waterproof rubber ring 50. The waterproof rubber ring 50 is made of silicone or rubber. The waterproof rubber ring 50 includes an outer sealing ring 51, a covering ring 52 and an inner sealing ring 53 that are integrally connected in sequence. The outer sealing ring 51 is located behind the retaining ring 302. The covering ring 52 completely covers the retaining ring 302. The inner sealing ring 53 is located in the opening of the insertion cavity 301.

[0039] Specifically, the housing 30 includes an inner shell 31 and an outer shell 32. The inner shell 31 covers the outside of the insulating body 10, the insertion cavity 301 is located in the inner shell 31, the retaining ring 302 is located at the front end of the inner shell 31, the inner shell 31 is a seamless stretched metal shell, and the base 11 is covered by a shielding shell 33. The rear end of the inner shell 31 is tightly fitted with the shielding shell 33, and the sealing element is embedded and formed with the rear end opening of the inner shell 31 for a sealed fit. The outer shell 32 covers the outside of the inner shell 31, and the outer shell 32 is a metal stamping shell, which is not limited to this.

[0040] In addition, the outer sealing ring 51 has raised crests 511, which protrude from the outer peripheral side of the retaining ring 302. There may be one or two crests 511, and the number is not limited. The rear side of the outer sealing ring 51 is a vertical surface. The front side of the covering ring 52 is a vertical surface, and the outer edge of the covering ring 52 has a guide slope 521. The guide slope 521 extends backward and outward at an angle to mate with the insertion interface of the equipment housing, so as to avoid damage to the waterproof rubber ring 50 during the insertion and installation, thereby helping to ensure the waterproof effect. The inner sealing ring 53 has a triangular cross-section and an arc-shaped convex structure on its outer surface. It includes an inlet surface 531, a contact surface 532, and a support surface 533 connected from front to back. The inlet surface 531 is used to insert the male head 40 into the insertion cavity 301. The contact surface 532 is used to make close contact with the outer wall of the male head 40. The support surface 533 is used to provide support, thus facilitating the formation of a better waterproof sealing structure with the outer wall of the male head 40.

[0041] Furthermore, the USB Type-C female connector that can be used underwater with power can be a board-mounted, recessed, vertical, or horizontal USB Type-C female connector, and its structural form is not limited.

[0042] The usage method of this embodiment is described in detail below:

[0043] When in use, install this product onto the circuit board of the electronic device and ensure that the outer sealing ring 51 fits tightly against the inner side of the insertion interface of the device housing. When the male connector 40 is inserted into the insertion cavity 301, the terminals inside the male connector 40 make contact with the contact portion 21 of the terminal group 20 and conduct electricity. At the same time, the inner sealing ring 53 seals against the outer wall of the male connector 40, effectively preventing external water from entering the insertion cavity 301, achieving the purpose of complete waterproofing, and allowing it to be immersed in water for live operation.

[0044] The key design feature of this invention is that the waterproof rubber ring is formed by integrally connecting an outer sealing ring, a covering ring, and an inner sealing ring. The outer sealing ring seals against the external device housing, and the inner sealing ring seals against the outer wall of the male connector, effectively preventing water from entering the insertion cavity. This achieves multiple layers of waterproofing, resulting in complete waterproofing. After the male connector is inserted into the insertion cavity, it can be used underwater while powered without the risk of short circuits or damage due to water ingress, thus providing convenience for users. Furthermore, the covering ring completely covers the retaining ring, preventing the front end of the housing from being exposed, thus better protecting the housing and preventing damage from impacts and scratches, which helps extend the product's service life.

[0045] 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.
