Structurally Enhanced Type-C Connector

Abstract

This utility model discloses a structurally enhanced Type-C connector, including a positioning element, an insulating body, upper terminals, lower terminals, and a shielding shell. The positioning element comprises a main body and two middle clips, which are inlaid and molded on the left and right sides of the main body. These two middle clips are positioned between multiple upper terminals and multiple lower terminals. This Type-C connector structure, by injection molding the two middle clips into the positioning element, effectively enhances the structural strength of the positioning element. During the transportation of semi-finished products, when the semi-finished products are subjected to vibration or external forces, the positioning element is less prone to deformation. Furthermore, the connection structure between the middle clips and the positioning element is stable, preventing the middle clips from falling off. This facilitates production, improves product quality, makes the product more competitive, and meets current needs.

Description

Technical Field

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

[0002] Type-C is significantly smaller than both Type-A and Type-B, making it a slim and compact new type of 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 a positioning element, an insulating body, multiple upper terminals, multiple lower terminals, and two center clips. The positioning element has multiple upper and lower mounting slots on its upper and lower surfaces, and center mounting slots on its left and right sides. The two center clips are mounted into their corresponding center mounting slots for interference fixation, the upper terminals into their corresponding upper mounting slots for interference fixation, and the lower terminals into their corresponding lower mounting slots for interference fixation, thus assembling a semi-finished product. This is then used to injection mold the insulating body. While this structure is relatively simple, during transportation of the semi-finished product, the center clips can easily detach from the center mounting slots when subjected to vibration or external forces. Furthermore, because the positioning element is made of plastic, its strength is insufficient, leading to easy deformation, causing production inconvenience, resulting in generally lower product quality, and making the product less competitive and unable to meet current demands. Therefore, it is necessary to research a new technical solution to improve the current Type-C connector. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a structurally enhanced Type-C connector. This effectively solves the problems of existing Type-C connectors where, during the transportation of semi-finished products, the middle clip easily detaches from the mounting slot when subjected to vibration or external force, and the plastic positioning component is not strong enough, leading to easy deformation of the positioning component, causing inconvenience to production, resulting in mediocre product quality and a lack of competitiveness.

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

[0006] A structurally enhanced Type-C connector includes a positioning element, an insulating body, upper terminals, lower terminals, and a shielding shell. The upper surface of the positioning element has multiple first positioning grooves, with first limiting blocks on both sides of each first positioning groove. The lower surface of the positioning element has multiple second positioning grooves, with second limiting blocks on both sides of each second positioning groove. The insulating body covers the positioning element and includes a base and a tongue extending from the base. Multiple upper terminals are respectively positioned in corresponding first positioning grooves, with each upper terminal positioned between two adjacent first limiting blocks. The multiple upper terminals are housed within the insulating body, and their upper contact portions are exposed. On the upper surface of the tongue plate, the upper welding portions of the plurality of upper terminals all extend beyond the base; there are a plurality of lower terminals, each of which is respectively disposed in a corresponding second positioning groove for positioning, and each lower terminal is disposed between two adjacent second limiting blocks. The plurality of lower terminals are disposed in the insulating body, and the lower contact portions of the plurality of lower terminals are exposed on the lower surface of the tongue plate. The lower welding portions of the plurality of lower terminals all extend beyond the base; the shielding shell covers the insulating body; the positioning component includes a main body and two middle clips, which are inlaid and formed on the left and right sides of the main body to effectively enhance the overall structural strength of the positioning component. The two middle clips are disposed between the plurality of upper terminals and the plurality of lower terminals.

[0007] As a preferred embodiment, the upper and / or lower surfaces of the positioning member are provided with positioning protrusions, the surfaces of which are flush with the surfaces of the tongue portion. These positioning protrusions are used to assist in positioning the product during injection molding of the insulating body, thereby improving the quality of injection molding.

[0008] As a preferred embodiment, the positioning bump includes an upper positioning bump and a lower positioning bump. The upper positioning bump is located on the upper surface of the positioning member, and the upper surface of the upper positioning bump is flush with the upper surface of the tongue plate. The lower positioning bump is located on the lower surface of the positioning member, and the lower surface of the lower positioning bump is flush with the lower surface of the tongue plate. The arrangement of the upper and lower positioning bumps facilitates the positioning of the product when the insulating body is injection molded, bringing convenience to production and improving product quality.

[0009] As a preferred embodiment, through holes are formed on the upper and lower surfaces of the left and right sides of the positioning member, and the insulating body is filled in the two through holes, which effectively enhances the stability of the connection structure between the insulating body and the positioning member.

[0010] As a preferred embodiment, the rear end of the base is provided with a dispensing groove, which is filled with waterproof adhesive to form a waterproof component. The upper welding parts of the multiple upper terminals and the lower welding parts of the multiple lower terminals all pass through the dispensing groove and are embedded and fixed together with the waterproof component, effectively enhancing the waterproof performance of the product.

[0011] As a preferred option, a waterproof ring is further provided, which is located at the front end of the shielding shell to further enhance the waterproof performance of the product.

[0012] As a preferred embodiment, a metal outer shell is further provided, which covers the shielding shell. The metal outer shell is fixedly connected to the shielding shell by spot welding, and multiple weld points are formed on the surface of the metal outer shell.

[0013] As a preferred embodiment, the metal casing is provided with fixing holes on the left and right sides for fixing with external parts.

[0014] As a preferred embodiment, the inner surface of the upper terminal is fitted to the bottom surface of the first positioning groove, and the connection structure between the upper terminal and the positioning member is stable. The inner surface of the lower terminal is fitted to the bottom surface of the second positioning groove, and the connection structure between the lower terminal and the positioning member is stable.

[0015] As a preferred embodiment, both the positioning element and the insulating body are made of insulating plastic.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By setting the positioning component, which includes a main body and two middle clips, the two middle clips are inlaid and molded on the left and right sides of the main body. These two middle clips are positioned between multiple upper terminals and multiple lower terminals. This type of Type C connector, with the two middle clips injection molded into the positioning component, can effectively enhance the structural strength of the positioning component. During the transportation of semi-finished products, when the semi-finished products are subjected to vibration or external forces, the positioning component is not easily deformed. Moreover, the connection structure between the middle clips and the positioning component is stable, so the middle clips will not fall off. This brings convenience to production, improves product quality, makes the product more competitive, and meets current needs.
