Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically to a waterproof connector. Background Technology

[0002] Electronic devices using Universal Serial Bus (USB) output ports are used in a variety of environments, with increasingly stringent requirements for environmental performance, including safe operation in harsh environments with high humidity. Because the structure and manufacturing process of Type-C USB connector receptacles involves separately injection molding the core and then assembling it with the connecting pins (contact terminals), current technology often uses an insulating shell and receptacle body that work together to form the USB receptacle. Type-A USB connector receptacles on the market are not waterproof, have lower safety performance, and can easily pose safety hazards. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a waterproof connector, comprising a metal shell and an insulator assembly enclosed by the metal shell. A terminal assembly is installed within the insulator assembly, the terminal assembly including an insertion portion and a soldering portion. The insulator assembly includes a first insulator, which wraps around the insertion portion. A shielding member covers the first insulator, and through slots are provided on both sides of the shielding member for the first insulator to pass through. A sealing member is provided at the end of the first insulator away from the insertion portion, the sealing member being perpendicular to the insertion portion.

[0004] Furthermore, the first insulator includes a wrapping portion and a fixing portion. The wrapping portion is formed by injection molding and wraps around the insertion portion. The fixing portion is located between the insertion portion and the welding portion and has a cross-section larger than the wrapping portion. The sealing member is closely attached to the side of the fixing portion away from the wrapping portion. The sealing member is made of an elastic material and has a cross-section larger than the fixing portion.

[0005] Furthermore, the shielding component includes a shielding part and a connecting part. The shielding part covers the wrapping part, and the connecting part is fixedly connected to the fixing part by an interference fit. The shielding part includes a first shielding plate and a second shielding plate arranged in parallel. The first shielding plate and the second shielding plate respectively cover the top and bottom of the wrapping part, and the through groove is located between the first shielding plate and the second shielding plate.

[0006] Furthermore, the fixing part is provided with a plurality of protrusions, which are used to form an interference fit between the connecting part and the fixing part when the connecting part contacts the fixing part.

[0007] Furthermore, a waterproof sleeve is provided between the metal casing and the first insulator, with one end of the waterproof sleeve snapped between the sealing member and the metal casing.

[0008] Furthermore, an opening is formed at the end of the waterproof sleeve away from the metal shell for inserting other connectors, and a sealing ring is fitted over the opening.

[0009] Furthermore, the insulator assembly also includes a second insulator that wraps around the welded portion, and the sealing member is located between the first and second insulators. A pair of limiting portions extend from both sides of the end of the second insulator facing the first insulator, and the sealing member is located between the limiting portions.

[0010] Furthermore, several pins are provided at the bottom of the metal casing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This application provides a sealing member at the end of the first insulator away from the insertion part, and makes it perpendicular to the insertion part, thereby preventing external water from flowing into the soldering part and circuit board through the gap between the first insulator and the metal shell, which would cause circuit failure. In addition, this application also provides through grooves on both sides of the shielding member, so that after the shielding member is inserted, it will not affect the distance between the two sides of the first insulator and the metal shell, thereby facilitating the insertion part to form an electrical connection with other connectors.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0028] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0029] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, a waterproof connector includes a metal housing 100 and an insulator assembly 200 enclosed by the metal housing 100. A terminal assembly 300 is installed within the insulator assembly 200. The terminal assembly 300 includes an insertion portion 310 and a soldering portion 320. The insertion portion 310 is used to insert into other connectors to form an electrical connection, and the soldering portion 320 is used to connect to a circuit board (not shown in the figure). The insulator assembly 200 includes a first insulator 210, which is wrapped around the insertion portion 310. A shielding member 400 covers the first insulator 210. Through slots 430 are provided on both sides of the shielding member 400 for the first insulator 210 to pass through. A sealing member 500 is provided at the end of the first insulator 210 away from the insertion portion 310. The sealing member 500 is perpendicular to the insertion portion 310.

[0030] In the implementation of this application, the first insulator 210 and the insertion part 310 of the terminal assembly 300 are first assembled together by injection molding. During this process, a sealing member 500 is provided at the end of the first insulator 210 away from the insertion part 310. Finally, the shielding member 400 is inserted from one end of the first insulator 210 so that it covers the first insulator 210.

[0031] Compared with the prior art, this application provides a sealing member 500 at the end of the first insulator 210 away from the insertion part 310, and makes it perpendicular to the insertion part 310. This can prevent external water from flowing into the soldering part 320 and the circuit board through the gap between the first insulator 210 and the metal shell 100, which would cause circuit failure. In addition, this application also provides through grooves 430 on both sides of the shield 400. After the shield 400 is inserted, it will not affect the distance between the two sides of the first insulator 210 and the metal shell 100, thereby facilitating the electrical connection between the insertion part 310 and other connectors.

[0032] Furthermore, based on the above embodiments, such as Figure 2 As shown, the first insulator 210 includes a wrapping portion 211 and a fixing portion 212. The wrapping portion 211 is formed by injection molding and wraps around the insertion portion 310. The fixing portion 212 is located between the insertion portion 310 and the welding portion 320 and has a cross-section larger than the wrapping portion 211. The sealing member 500 is closely attached to the side of the fixing portion 212 away from the wrapping portion 211. The sealing member 500 is made of elastic material and has a cross-section larger than the fixing portion 212. In this way, when the metal shell 100 wraps the insulator assembly 200, it forms a compression around the sealing member 500, thereby ensuring that external water cannot flow into the welding portion 320 and the circuit board through the gap between the first insulator 210 and the metal shell 100.

[0033] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3As shown, the shielding component 400 includes a shielding portion 410 and a connecting portion 420. The shielding portion 410 covers the wrapping portion 211, and the connecting portion 420 is fixedly connected to the fixing portion 212 through an interference fit, so that the entire shielding component 400 can be firmly fixed together with the first insulator 210. The shielding portion 410 includes a first shielding plate 411 and a second shielding plate 412 arranged in parallel. The first shielding plate 411 and the second shielding plate 412 cover the top and bottom of the wrapping portion 211, respectively. The through groove 430 is located between the first shielding plate 411 and the second shielding plate 412. In this way, when the shielding component 400 is inserted from one end of the first insulator 210, the top of the wrapping portion 211 is covered by the first shielding plate 411 and the second shielding plate 412, respectively. The through groove 430 passes through both sides of the wrapping portion 211. Since the shielding portion 410 does not affect the distance between the wrapping portion 211 and the metal shell 100, the entire shielding component 400 will not affect the connection of the insertion portion 310 with other connectors.

[0034] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, a plurality of protrusions 212a are provided on the fixing part 212. When the connecting part 420 contacts the fixing part 212, the protrusions 212a are used to form an interference fit between the connecting part 420 and the fixing part 212, thereby ensuring that the shielding member 400 can be firmly fixed together with the first insulator 210.

[0035] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4 As shown, a waterproof sleeve 600 is provided between the metal shell 100 and the first insulator 210. One end of the waterproof sleeve 600 is snapped between the sealing member 500 and the metal shell 100, thereby further improving the airtightness between the sealing member 500 and the metal shell 100. The other end of the waterproof sleeve 600 extends out of the metal shell 100 along the insertion part 310.

[0036] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4 As shown, an opening 610 for inserting other connectors is formed at the end of the waterproof sleeve 600 away from the metal shell 100. A sealing ring 620 is fitted around the outside of the opening 610. When the other connector is connected to the insertion through the opening 610, the sealing ring 620 can prevent external water from entering the waterproof sleeve 600 through the opening 610, thereby further improving the waterproof performance.

[0037] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, the insulator assembly 200 further includes a second insulator 220, which wraps around the welded portion 320. The sealing member 500 is located between the first insulator 210 and the second insulator 220. A pair of limiting portions 221 extend from both sides of the end of the second insulator 220 facing the first insulator 210. The sealing member 500 is located between the limiting portions 221, so that the sealing member 500 is limited on all sides, which can further prevent the sealing member 500 from shaking and causing the sealing effect to deteriorate.

[0038] Furthermore, based on the above embodiments, such as Figure 5 As shown, a plurality of pins 110 are provided at the bottom of the metal casing 100, and the pins 110 are used to fix the entire product onto the circuit board.

[0039] Furthermore, this application also provides a second embodiment, combined with Figure 6 , Figure 7 and Figure 8 As shown, the difference from the first embodiment is that the terminal assembly 300 further includes a partition plate 330, which is partially covered by the wrapping portion 211. The through slot 430 is only for the partition plate 330 to pass through. Thus, compared with the first embodiment, the through slot 430 is narrower, and the electromagnetic shielding effect is better while affecting the distance between the two sides of the first insulator 210 and the metal shell 100.

[0040] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
