Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a TYPE-C connector with an anti-loosening structure. Background Art

[0002] Type-C is an interface standard that is smaller than Type-A and Type-B. It can be used for both PCs (master devices) and external devices (slave devices, such as mobile phones).

[0003] In existing technology, the Type-C connector is primarily used in portable devices or those that need to transmit large amounts of data. Compared to conventional USB interfaces, it is smaller and lacks an internal snap-fit ​​mechanism, requiring only a slight force to plug and unplug. While convenient, it also has the problem of being easily loosened. Furthermore, for Type-C connectors with built-in chips, the internal PCB lacks protection, making it susceptible to damage from drops and vibrations.

[0004] In light of this, this technical solution proposes a TYPE-C connector with an anti-loosening structure. The anti-slip structure at the interface provides strong friction after insertion, preventing it from loosening. In addition, protective components are added to the internal PCB and chip to prevent damage. Utility Model Content

[0005] The present invention aims to address, at least to a certain extent, one of the technical problems in the related art. To this end, the present invention primarily aims to provide a Type-C connector with an anti-loosening structure, addressing the existing Type-C connector's difficulty in loosening after insertion and its lack of protection for internal components.

[0006] To achieve the above-mentioned purpose, the present invention provides a TYPE-C connector with an anti-loosening structure, comprising a connector body,

[0007] The connector body includes an outer shell and an inner shell sleeved in the outer shell.

[0008] The bracket in the inner shell is fixed with a connecting terminal. A mounting seat is provided on one side of the bracket. The mounting seat is a frame-shaped structure and fixes the PCB. One side of the PCB passes through the mounting seat and is connected to the connecting terminal.

[0009] The inner shell is provided with a through hole near the opening position, and a convex anti-slip bump is provided in the through hole. The anti-slip bump is a rubber block structure, and the bottom is fixedly engaged with the inside of the through hole.

[0010] As a further solution of the present invention, the inner shell is a two-side shell clamping structure, and the anti-slip protrusions are provided on both sides of the inner shell.

[0011] As a further solution of the present invention, the anti-slip protrusion is an inwardly expanded barbed hook-shaped protrusion structure.

[0012] As a further solution of the present invention, one side of the inner shell is provided with a clamping hole for connecting with the outer shell, and an anti-separation positioning piece is provided between each of the clamping holes.

[0013] As a further solution of the present invention, a heat dissipation hole is opened on the surface of the inner shell for dissipating the internal working heat. One side of the heat dissipation hole is in contact with the outer shell, and the other side is close to the PCB.

[0014] As a further solution of the present invention, snap-fit ​​ribs are provided on both sides of the inner shell for further fixing the outer shell.

[0015] As a further solution of the present invention, the snap-fit ​​rib is arranged on the side of the mounting seat.

[0016] The beneficial effects of the utility model are as follows:

[0017] This Type-C connector with an anti-loosening structure features anti-slip bumps located near the connector opening. During insertion, these bumps are positioned at the bottom of the socket, resulting in a longer separation distance. Furthermore, the rubber bumps provide greater friction, making insertion and removal easier, while maintaining a stable connection and resisting loosening. Furthermore, a mounting bracket protects the internal PCB, enclosing the PCB and various chip components to prevent damage from drops, vibration, and other factors. The overall structure is simple, making it easy to assemble and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] as follows:

[0025] Please see the attached Figure 1-3 ,

[0026] The main structure includes a connector body 1, which includes an outer shell 10 and an inner shell 11 that is sleeved in the outer shell 10, a bracket 12 in the inner shell 11, and a connecting terminal 120 is fixed on the bracket 12. A mounting seat 13 is provided on one side of the bracket 12. The mounting seat 13 is a frame-shaped structure and frames and fixes the PCB130. One side of the PCB130 passes through the mounting seat 13 and is connected to the connecting terminal 120. A through hole 114 is provided near the opening position of the inner shell 11, and a raised anti-slip bump 115 is provided in the through hole 114. The anti-slip bump 115 is a rubber block structure, and the bottom is fixed to the inside of the through hole 114.

[0027] Here's how it works:

[0028] On either side (or one side) of the bracket 12 with the connecting terminals 120 are anti-slip bumps 115 located on the inner wall of the inner housing 11. These anti-slip bumps 115 are located near the opening of the connector body 1. When plugged in, these anti-slip bumps 115 are located at the bottom of the plug hole, allowing for a longer travel when unplugging. Furthermore, because these anti-slip bumps 115 are rubber bumps with high friction, they provide a stable connection and are easy to plug in and out. The mounting base 13 frames the PCB 130 for protection, and rubber strips can be installed on the inner wall of the mounting base 13 to further protect the PCB 130.

[0029] In a preferred embodiment of the present invention, the inner shell 11 is a two-side shell clamping structure, and anti-slip protrusions 115 are provided on both sides of the inner shell 11.

[0030] The anti-slip bumps 115 can be set on one side or both sides of the inner wall of the internal shell. When set as a two-sided structure, a little force is required for plugging and unplugging, but the connection strength is greater than that of a single-sided structure.

[0031] In a preferred embodiment of the present invention, the anti-slip protrusion 115 is an inwardly expanded barbed hook-shaped protrusion structure.

[0032] The inward expansion is convenient for insertion but not easy for removal. It is an oblique hook-shaped protrusion structure.

[0033] In a preferred embodiment of the present invention, one side of the inner shell 11 is provided with a clamping hole 110 for connecting with the outer shell 10 , and an anti-separation positioning piece 111 is provided between each clamping hole 110 .

[0034] In a preferred embodiment of the present invention, a heat dissipation hole 112 is provided on the surface of the inner shell 11 for dissipating the internal working heat. One side of the heat dissipation hole 112 contacts the outer shell 10 and the other side is close to the PCB 130.

[0035] The heat dissipation holes 112 are provided to dissipate the working heat of the main internal heat source (PCB 130 and various components and chips).

[0036] A preferred embodiment of the present invention is that both sides of the inner shell 11 are provided with snap-fit ​​ribs 113 for further fixing the outer shell 10. The snap-fit ​​ribs 113 are arranged at the side positions of the mounting seat 13.

[0037] The mounting base 13 not only has the function of framing and protecting the PCB 130 , but also has the function of further fixing the outer shell 10 .

[0038] The above are only preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. All equivalent structural transformations made by using the contents of the description and drawings of the technical solution of the present utility model under the conception of the technical solution of the present utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the present utility model.
