Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a simplified Type-C plug connector with enhanced structure. Background Technology

[0002] Type-C connectors, commonly referred to as Type-C interfaces, are a new type of USB interface that can be inserted in either direction. This design greatly improves user convenience, as it eliminates the need to distinguish between the correct and reverse sides, unlike traditional USB interfaces. Type-C interfaces are not only suitable for data transmission but also support high-power transmission and video transmission. With its reversible insertion, high transmission speed, strong power delivery capability, video transmission function, wide interface versatility, and support for multiple protocols, Type-C connectors are gradually replacing traditional USB interfaces and becoming the mainstream trend for future electronic device interfaces.

[0003] The current Type-C plug connector mainly consists of an insulating body, a shielding shell, multiple terminals, and a latching hook. The insulating body has a forward-facing insertion cavity. The shielding shell covers the insulating body. The multiple terminals are disposed within the insulating body, each terminal having a contact portion and a solder portion. The contact portion is suspended in the insertion cavity, and the solder portion is exposed at the rear end of the insulating body. The latching hook is disposed within the insulating body.

[0004] However, in existing technologies, the hook components are all metal sheet structures, formed by stamping using a stamping die. This process is difficult and costly. Furthermore, during assembly, a through-slot needs to be cut into the insulation body, penetrating both ends, before the hook component is inserted from back to front. This assembly structure results in large gaps that easily trap dirt and grime, allowing external dust and moisture to easily penetrate the product's rear end, leading to poor waterproofing and dustproofing, and failing to meet usage requirements. Therefore, it is necessary to improve the current Type-C plug 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 simplified Type-C plug connector with enhanced structure, which can effectively solve the problems of high manufacturing difficulty, high cost, and poor waterproof and dustproof performance of existing Type-C plug connectors.

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

[0007] A simplified Type-C plug connector with reinforced structure includes an insulating body, a shielding shell, multiple terminals, and a latching hook. The insulating body has a forward-opening insertion cavity. The shielding shell covers the insulating body. The multiple terminals are disposed within the insulating body, each terminal having a contact portion and a solder portion. The contact portion is suspended in the insertion cavity, and the solder portion protrudes from the rear end of the insulating body. The latching hook is disposed within the insulating body. A positioning groove is recessed on one outer surface of the insulating body, and slots are formed on both the left and right sides of the insulating body, the two slots connecting the outside and the insertion cavity, and the two slots respectively connecting to the two ends of the positioning groove. The latching hook is integrally formed by bending metal wire and includes a positioning portion and two hook-holding portions. The positioning portion is embedded in the positioning groove for positioning, and the two hook-holding portions are bent and extended from the left and right ends of the positioning portion, respectively. The two hook-holding portions are suspended in the two slots, and the two hook-holding portions partially extend into both sides of the insertion cavity, and the two hook-holding portions are laterally elastically movable inward and outward.

[0008] As a preferred embodiment, the positioning groove is U-shaped, and correspondingly, the positioning part is U-shaped, which includes a transverse section and two longitudinal sections. The two longitudinal sections are bent and extended from the left and right ends of the transverse section, and both longitudinal sections extend backward. The structure is simple and the positioning is more stable.

[0009] As a preferred embodiment, the hook portion includes a vertical section and an inclined section. The vertical section extends downwards at the tail end of the longitudinal section, with a portion of the vertical section exposed in the insertion cavity. The inclined section extends upwards at the lower end of the vertical section, with the inclined section facing the inner wall of the shielding shell. The structure is simple and has good elasticity.

[0010] As a preferred embodiment, the metal wire is steel wire.

[0011] As a preferred embodiment, the rear end face of the insulating body is provided with multiple terminal slots, all of which are connected to the insertion cavity. The multiple terminals are inserted into the corresponding terminal slots from back to front and tightly fitted and fixed to facilitate quick assembly of the terminals.

[0012] As a preferred embodiment, the rear edge of both surfaces of the insulating body is provided with a limiting protrusion, and the rear end face of the shielding shell abuts against the front side of the limiting protrusion to prevent the shielding shell from shifting backward relative to the insulating body.

[0013] As a preferred embodiment, at least one surface of the rear end of the insulating body is provided with a protruding buckle, and correspondingly, the shielding shell is provided with a buckle hole. The protruding buckle and the buckle hole cooperate to lock and fix the structure, which is simple and easy to assemble.

[0014] As a preferred embodiment, the terminal has a harpoon-shaped structure, which is simple in structure and easy to manufacture.

[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 hook part to be formed by bending a metal wire in one piece, replacing the traditional metal sheet structure, there is no need to use stamping molds for stamping, saving molds, making manufacturing easier, and effectively reducing manufacturing costs. At the same time, the installation of the hook part does not require opening a through groove in the insulation body, making it less likely to accumulate dirt and grime. External dust and moisture are also less likely to enter the end of the product, resulting in better waterproof and dustproof performance and meeting the needs of use.

[0039] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a shielding shell 20, multiple terminals 30, and a hook 40.

[0040] The insulating body 10 has a forward-opening insertion cavity 11. A positioning groove 12 is recessed on one outer surface of the insulating body 10. Slots 13 are formed on both the left and right sides of the insulating body 10, connecting the outside to the insertion cavity 11 and respectively connecting to both ends of the positioning groove 12. In this embodiment, the positioning groove 12 is U-shaped. Furthermore, a plurality of terminal slots 14 are formed on the rear end face of the insulating body 10, all of which communicate with the insertion cavity 11. Additionally, limiting protrusions 15 are protruding from the rear end edges of both surfaces of the insulating body 10. At least one rear end surface of the insulating body 10 has a protruding buckle 16. Moreover, a fixing groove 17 is recessed on the rear end face of the insulating body 10.

[0041] The shielding shell 20 covers the insulating body 10. In this embodiment, the shielding shell 20 is made of metal and is formed by stamping or stretching. The rear end face of the shielding shell 20 abuts against the front side of the limiting protrusion 15 to prevent the shielding shell 20 from moving backward relative to the insulating body 10. Furthermore, the shielding shell 20 has a snap-fit ​​hole 21, and the protruding buckle 16 engages with the snap-fit ​​hole 21 to secure it, preventing the shielding shell 20 from dislodging forward from the insulating body 10, thus ensuring a stable connection between the shielding shell 20 and the insulating body 10. Additionally, two fixing feet 22 extend rearward from both sides of the rear end of the shielding shell 20, and the two fixing feet 22 are arranged vertically at intervals to form a clamping groove 201.

[0042] The plurality of terminals 30 are disposed within the insulating body 10. Each terminal 30 has a contact portion 31 and a solder portion 32. The contact portion 31 is suspended in the insertion cavity 11, and the solder portion 32 protrudes from the rear end of the insulating body 10. In this embodiment, the terminal 30 has a harpoon-shaped structure. Furthermore, the plurality of terminals 30 are respectively inserted into the corresponding terminal slots 14 from back to front and tightly fitted and fixed, resulting in a simple structure and convenient assembly.

[0043] The hook 40 is disposed within the insulating body 10. The hook 40 is integrally formed by bending a metal wire and includes a positioning part 41 and two hook-holding parts 42. The positioning part 41 is embedded in the positioning groove 12 for positioning. The two hook-holding parts 42 are bent and extended from the left and right ends of the positioning part 41, respectively. The two hook-holding parts 42 are suspended in the two slots 13, and each hook-holding part 42 partially extends into both sides of the insertion cavity 11. The two hook-holding parts 42 are laterally elastically movable inwards and outwards. In this embodiment, the metal wire is steel wire, but it can also be other metal wires with appropriate rigidity and elasticity, without limitation. Specifically, the positioning part 41 is U-shaped, including a transverse section 411 and two longitudinal sections 412. The two longitudinal sections 412 are bent and extended from the left and right ends of the transverse section 411, respectively, and both longitudinal sections 412 extend rearwards. The hook portion 42 includes a vertical section 421 and an inclined section 422. The vertical section 421 extends downward vertically from the tail end of the longitudinal section 412, and a portion of the vertical section 421 is exposed in the insertion cavity 11. The inclined section 422 extends upward inclinedly from the lower end of the vertical section 421, and the inclined section 422 faces the inner wall of the shielding shell 20.

[0044] Furthermore, it further includes a PCB board 50, the front end of which is inserted into the fixing groove 17 and fixed, and the PCB board 50 extends rearward. The PCB board 50 has multiple pads 51, and the soldering parts 32 of the multiple terminals 30 are respectively soldered and fixed to the corresponding pads 51 and connected in a conductive manner. The two ends of the PCB board 50 are respectively clamped in the clamping grooves 201 on both sides of the rear end of the shielding shell 20, and each fixing foot 22 is soldered and fixed to the PCB board 50.

[0045] The assembly process of this embodiment is described in detail below:

[0046] First, assemble and fix multiple terminals 30 from back to front into their corresponding terminal slots 14. Next, assemble the hooks 40 from top to bottom onto the insulating body 10, so that the positioning part 41 is embedded in the positioning slot 12 for positioning, and the two hooks 42 are suspended in the two slots 13 respectively. Then, fit the shielding shell 20 onto the insulating body 10 from front to back for fixation. Finally, assemble the PCB board 50 onto the rear end of the insulating body 10, and weld and fix the soldering parts 32 of multiple terminals 30 to their corresponding solder pads 51 for conductive connection. At the same time, weld and fix each fixing foot 22 to the PCB board 50.

[0047] During use, after this product is properly connected to an external Type-C socket connector, the vertical sections 421 of the two hooks 42 elastically engage with the slots on both sides of the tongue plate of the Type-C socket connector. This enhances the insertion and extraction force and prevents the product from easily detaching from the Type-C socket connector. When it is necessary to separate this product from the Type-C socket connector, simply pull the product outwards. The two hooks 42 will then elastically move outwards and disengage from their corresponding slots, allowing the product to be pulled out.

[0048] The key design feature of this invention is that the hook is made of integrally formed and bent metal wire, replacing the traditional sheet metal structure. This eliminates the need for stamping with a die, saving on molds, making manufacturing easier, and effectively reducing production costs. Furthermore, the hook eliminates the need for through slots on the insulating body, preventing dirt and grime buildup. External dust and moisture are also less likely to enter the product's end, resulting in better waterproofing and dustproofing, thus meeting usage requirements.

[0049] 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.
