Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a USB Type-C waterproof connector with raised ribs. Background Technology

[0002] Type-C is a USB interface standard that is smaller than both Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). USB Type-C has 4 pairs of TX / RX pins, 2 pairs of USB D+ / D- pins, 1 pair of SBU pins, 2 CC pins, 4 VBUS pins, and 4 ground pins.

[0003] The current USB Type-C waterproof connector mainly consists of an insulating body, a middle clip, multiple conductive terminals, and a shielding shell. The insulating body includes a base and a tongue extending forward from the base, with a dispensing groove on the base. The middle clip and multiple conductive terminals are housed within the insulating body, arranged in two rows. The middle clip is positioned between the two rows of conductive terminals and passes through the dispensing groove, which is filled with waterproof adhesive to form a sealing element. This sealing element is embedded and fixed together with the middle clip and multiple conductive terminals. Each conductive terminal has a contact... The contact parts and welding parts of multiple conductive terminals are exposed on both surfaces of the tongue plate, and the welding parts of multiple conductive terminals extend out of the base; the shielding shell includes an inner shell, an EMI sleeve, and an outer shell; the inner shell is a seamless stretched shell that covers the insulating body; the EMI sleeve is also a seamless stretched shell that is fitted onto the rear end of the insulating body and seals with the inner wall of the rear end of the inner shell, and the aforementioned sealing element is sealed and fixed together with the rear end of the EMI sleeve and the inner shell; the outer shell is a stamped shell that is fitted onto the outer side of the inner shell and fixed to the inner shell by spot welding.

[0004] However, in existing technologies, due to tolerance issues, the EMI sleeve, fitted onto the rear end of the insulating body, cannot fit tightly within the insulating body. This results in a gap between the EMI sleeve and the insulating body, causing waterproof adhesive to easily overflow along this gap to the front end of the tongue plate after being injected into the dispensing groove. This prevents effective waterproof sealing and may even cover the contact areas of the conductive terminals, leading to product defects. Therefore, it is necessary to improve the current USB Type-C waterproof connector. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a USB Type-C waterproof connector with ribs, which can effectively solve the problem that waterproof glue easily overflows to the front end of the tongue plate when the existing USB Type-C waterproof connector is injected into the dispensing groove.

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

[0007] A waterproof USB Type-C connector with raised ribs includes an insulating body, a central clip, multiple conductive terminals, and a shielding shell. The insulating body includes a base and a tongue extending forward from the base, with a dispensing groove on the base. The central clip and multiple conductive terminals are disposed within the insulating body, arranged in two rows. The central clip is located between the two rows of conductive terminals and passes through the dispensing groove, which is filled with waterproof adhesive to form a sealing element. The sealing element is embedded and fixed together with the central clip and multiple conductive terminals. Each conductive terminal has a contact portion and a soldering portion. The contact portions of the multiple conductive terminals are exposed on both surfaces of the tongue, and the soldering portions of the multiple conductive terminals are... All parts extend beyond the base; the shielding shell includes an inner shell, an EMI sleeve, and an outer shell; the inner shell is a seamless stretched shell that covers the insulating body; the EMI sleeve is also a seamless stretched shell, which is fitted onto the rear end of the insulating body and seals against the inner wall of the rear end of the inner shell, and the aforementioned seal is sealed and fixed together with the rear end of the EMI sleeve and the inner shell; the outer shell is a stamped shell, which is fitted onto the outer side of the inner shell and fixed to the inner shell by spot welding; a raised rib is provided on the outer peripheral side of the rear end of the insulating body, the raised rib is annular, the raised rib is tightly fitted with the inner peripheral side wall of the EMI sleeve, and a resist groove is formed behind the raised rib, the resist groove being located in front of the dispensing groove.

[0008] As a preferred embodiment, the rib is located on the outer peripheral side of the rear end of the tongue plate. The EMI sleeve includes an integrally formed front fitting part and a rear fitting part. The front fitting part fits onto the outer peripheral side of the rear end of the tongue plate and is tightly fitted with the rib. The rear fitting part fits onto the outer peripheral side of the base. The rear fitting part is attached to the inner peripheral side wall of the inner shell and fixed by spot welding to achieve a better waterproof sealing effect.

[0009] As a preferred embodiment, the ribs are arranged in two spaced-apart sections to better block the waterproof adhesive.

[0010] As a preferred embodiment, the outer peripheral side of the base is recessed with an adhesive receiving groove, which is annular and located between the dispensing groove and the blocking groove, to collect waterproof adhesive.

[0011] As a preferred embodiment, the insulating body is arranged horizontally or vertically.

[0012] As a preferred embodiment, the rib is located on the outer peripheral side of the base to more quickly block excess adhesive.

[0013] As a preferred embodiment, the EMI housing covers the front end face and outer peripheral side face of the base.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] By providing a raised rib on the outer peripheral side of the rear end of the insulating body, the raised rib can better fit tightly with the inner peripheral side wall of the EMI housing. At the same time, an adhesive-blocking groove is formed behind the raised rib. The adhesive-blocking groove can effectively prevent waterproof adhesive from overflowing forward. The waterproof adhesive will not overflow to the front end of the tongue plate, thus achieving effective waterproof sealing. At the same time, it will not cover the contact part of the conductive terminal, greatly improving the product yield.

[0039] The insulating body 10 includes a base 11 and a tongue plate 12 extending forward from the base 11. The base 11 has an adhesive groove 101, and a raised rib 102 protrudes from the outer peripheral side of the rear end of the insulating body 10. The raised rib 102 is annular. In this embodiment, the insulating body 10 is horizontally arranged. The outer peripheral side of the base 11 has a recessed adhesive receiving groove 103, which is annular in shape to hold waterproof adhesive. The cross-section of the adhesive receiving groove 103 is V-shaped. The raised rib 102 is located on the outer peripheral side of the rear end of the tongue plate 12, and there are two raised ribs 102 spaced apart, each with a convex arc-shaped cross-section.

[0040] The middle clip 20 and multiple conductive terminals 30 are both disposed within the insulating body 10. The multiple conductive terminals 30 are arranged in two rows, with the middle clip 20 located between the two rows of conductive terminals 30. The middle clip 20 and multiple conductive terminals 30 all pass through the dispensing groove 101, which is filled with waterproof adhesive to form a sealing element 50. The sealing element 50 is embedded and fixed together with the middle clip 20 and multiple conductive terminals 30. Each conductive terminal 30 has a contact portion 31 and a welding portion 32. The contact portions 31 of multiple conductive terminals 30 are exposed on both surfaces of the tongue plate 12, and the welding portions 32 of multiple conductive terminals 30 extend out of the base 11.

[0041] The shielding housing 40 includes an inner housing 41, an EMI sleeve 42, and an outer housing 43. The inner housing 41 is a seamless stretched shell that covers the insulating body 10. The EMI sleeve 42 is also a seamless stretched shell, fitted onto the rear end of the insulating body 10 and sealingly engaging with the inner rear wall of the inner housing 41. The aforementioned sealing element 50 is sealed and fixed together with the EMI sleeve 42 and the rear end of the inner housing 41. The outer housing 43 is a stamped housing, fitted onto the outer surface of the inner housing 41 and fixedly welded to the inner housing 41 by spot welding. The protruding rib 102 is tightly fitted with the inner peripheral sidewall of the EMI sleeve 42, and a resistive groove 401 is formed behind the protruding rib 102, which is located in front of the dispensing groove 101. In this embodiment, the aforementioned adhesive receiving groove 103 is located between the dispensing groove 101 and the resistive groove 401. The EMI housing 42 includes an integrally formed front fitting portion 421 and a rear fitting portion 422. The front fitting portion 421 fits onto the outer peripheral side of the rear end of the tongue plate 12 and is tightly fitted with the protruding rib 102. The rear fitting portion 422 fits onto the outer peripheral side of the base 11 and is attached to the inner peripheral side wall of the inner housing 41 and fixed by spot welding. In addition, a waterproof ring 44 is fitted onto the outer peripheral side of the front end of the inner housing 41, and the waterproof ring 44 is located in front of the outer housing 43. Furthermore, the front end of the tongue plate 12 extends forward out of the inner housing 41.

[0042] The manufacturing and assembly process of this embodiment is described in detail below:

[0043] First, the middle clamping piece 20 and multiple conductive terminals 30 are stamped and formed. Then, the middle clamping piece 20 and multiple conductive terminals 30 are embedded and fixed onto the insulating body 10 by injection molding. Next, the EMI sleeve 42 is fitted and fixed onto the insulating body 10 from front to back. Then, the inner shell 41 is fitted onto the outside of the insulating body 10 and welded to the EMI sleeve 42. Then, the outer shell 43 is fitted onto the inner shell 41 and welded to the inner shell 41. Finally, waterproof glue is injected into the glue dispensing groove 101. Both the glue blocking groove 401 and the glue receiving groove 103 can accommodate excess waterproof glue, preventing the waterproof glue from penetrating forward into the front end of the tongue plate. After the waterproof glue cures, a seal 50 is formed.

[0044] Please refer to Figures 7 to 10 As shown, it illustrates the specific structure of the second preferred embodiment of the present invention. The specific structure of this embodiment is basically the same as that of the aforementioned first preferred embodiment, except that:

[0045] In this embodiment, the insulating body 10 is vertically positioned, allowing the product to be mounted vertically on the circuit board, meeting usage requirements. The raised rib 102 is located on the outer peripheral side of the base 11 to more quickly block excess adhesive. Furthermore, the EMI sleeve 42 covers the front end face and outer peripheral side of the base 11.

[0046] The manufacturing and assembly process of this embodiment is basically the same as that of the first preferred embodiment described above, and the manufacturing and assembly process of this embodiment will not be described in detail here.

[0047] The key design feature of this invention is that a raised rib is provided on the outer peripheral side of the rear end of the insulating body. The raised rib can better fit tightly with the inner peripheral side wall of the EMI housing. At the same time, an adhesive-blocking groove is formed behind the raised rib. The adhesive-blocking groove can effectively prevent waterproof adhesive from overflowing forward. The waterproof adhesive will not overflow to the front end of the tongue plate, thereby achieving effective waterproof sealing. At the same time, it will not cover the contact part of the conductive terminal, which greatly improves the product yield.

[0048] 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.
