Description

Technical Field

[0001] This utility model relates to the field of Type C connectors, and in particular to a structurally stable Type C connector. Background Technology

[0002] Type-C is significantly smaller than both Type-A and Type-B, making it a new type of slim and compact USB interface. Furthermore, Type-C is an interface type that can be used with both PCs (host devices) and external devices (slave devices, such as mobile phones), offering good practicality. Type-C also supports higher power transmission, up to 100W, with the fastest data transfer speeds reaching 10Gbps, supporting a wider range of high-power devices. Finally, Type-C is the latest USB interface form factor standard; this interface has no reversible orientation, allowing for easy plugging and unplugging, thus increasing application flexibility. Type-C connectors come in various specifications, including 6-pin, 12-pin, 16-pin, and 24-pin designs.

[0003] Current Type-C connectors typically consist of multiple terminals mounted on an insulating body, with a shielding shell encasing the insulating body. The outer wall of the insulating body and the inner wall of the shielding shell are fixed together via an interference fit. While this type of Type-C connector is simple in structure and can basically achieve data transmission, its structure is not robust enough. After repeated insertions and removals or under external impact, the insulating body is prone to detaching from the shielding shell. This results in poor product stability, easily damaging the connector, affecting the normal operation of equipment, posing significant safety hazards, poor product quality, short lifespan, and a poor user experience, failing to meet current needs. Therefore, it is necessary to research a new technical solution to improve current Type-C connectors. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a structurally stable Type C connector. It can effectively solve the problems of existing Type C connectors, such as insufficient structural stability, easy detachment of the insulating body from the shielding shell after repeated insertion and removal or impact by external forces, poor product structural stability, easy damage to the connector, affecting the normal operation of the equipment, posing a significant safety hazard, poor product quality, short service life, and poor user experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structurally stable Type-C connector includes an insulating body, terminals, and a shielding shell. The insulating body includes a base and a tongue extending from the base. First positioning blocks are provided on the left and right sides of the rear end of the base, and a second positioning block is provided on the lower surface of the rear end of the base, positioned between the two first positioning blocks. A riveting groove is provided on the upper surface of the rear end of the base. Multiple terminals are provided on the insulating body, with their contact portions exposed on both surfaces of the tongue and their solder portions extending beyond the base. The shielding shell covers the insulating body. Positioning grooves are provided on the left and right sides of the top rear end of the shielding shell, with two first positioning blocks positioned in their respective grooves. A notch is provided at the center of the bottom rear end of the shielding shell, positioned between the two positioning grooves, with a second positioning block positioned in the notch. A riveting buckle is provided at the top rear end of the shielding shell, positioned in the riveting groove for fixation.

[0007] As a preferred embodiment, the shielding shell has piercing grooves on its left and right sides and first fixing feet extending from the piercing grooves. The front side of the first fixing feet is provided with a step, and the bottom front end of the shielding shell has a protruding bulge. The bottom surface of the bulge is flush with the bottom surface of the two steps. During installation, the two first fixing feet are installed into the positioning holes of the PCB board for fixation.

This keeps the front and rear ends of the Type C connector balanced, preventing the front end from tilting due to a lighter front end and a heavier rear end. This facilitates better soldering of the product, brings convenience to production, and improves product quality.

[0008] As a preferred embodiment, there are two convex bulges, which are symmetrically arranged at the bottom front end of the shielding shell to further improve the stability of the product structure.

[0009] As a preferred embodiment, the rear left and right sides of the shielding shell are provided with second fixing feet, which are used to cooperate with the positioning holes on the PCB board for fixation, which can further improve the stability of the product structure and make the connection structure firm and reliable.

[0011] As a preferred embodiment, the lower rear surface of the base is provided with two fixing posts, which are symmetrically arranged on the second positioning block. These two fixing posts are used to cooperate with the slot structure on the PCB board for fixation, thereby improving the structural stability of the product.

[0012] As a preferred embodiment, the front end of the shielding shell is provided with two spring contacts, which makes the connection structure more stable and less prone to loosening when the product is mated with the external male connector.

[0013] As a preferred embodiment, the insulating body includes a lower insulating member, an upper insulating member, and an outer insulating member. The upper insulating member and the lower insulating member are stacked together, and the outer insulating member covers and is disposed outside the lower insulating member and the upper insulating member. The plurality of terminals includes a plurality of lower terminals and a plurality of upper terminals. The plurality of lower terminals are embedded and fixed on the lower insulating member. Each lower terminal includes a lower contact portion, a lower fixing portion, and a lower welding portion that are integrally formed and connected in sequence.

The plurality of upper terminals are embedded and fixed on the upper insulating member. Each upper terminal includes an upper contact portion, an upper fixing portion, and an upper welding portion that are integrally formed and connected in sequence. The upper contact portion is exposed on the upper surface of the outer insulating member, the upper fixing portion is embedded in the upper insulating member, and the upper welding portion extends rearward from the outer insulating member.

[0014] As a preferred embodiment, a middle clip is further provided, which is clamped between the lower insulating member and the upper insulating member and located between a plurality of lower terminals and a plurality of upper terminals.

[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 setting first positioning blocks on the left and right sides of the rear end of the base, and setting a second positioning block on the lower surface of the rear end of the base, with the second positioning block positioned between the two first positioning blocks, the two first positioning blocks are respectively set in the corresponding positioning grooves for positioning, and the second positioning block is set in the notch for positioning, and the rivet is set in the rivet groove for fixing, this type C connector structure can effectively enhance the stability of the structure, and the connection structure is firm and reliable.
