Description

Technical Field

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

[0002] With the rapid development of science and technology in the electronics industry, electronic products are becoming increasingly thinner and smaller. This necessitates smaller components, with the connector industry bearing the brunt of this trend. Existing USB interfaces include Type-A, Type-B, and Type-C. Among these, the Type-C interface is more streamlined and can be inserted in either direction for pairing, making it more suitable for use in increasingly miniaturized computing devices.

[0003] Currently, existing Type-C connectors typically include a shielding shell, an insulating body, an upper terminal group, an upper insulating component, a lower terminal group, and a lower insulating component. The shielding shell covers the insulating body and requires two injection molding processes during manufacturing. In the first injection molding, the upper terminal group is injection molded onto the upper insulating component to form the upper terminal module, and the lower terminal group is injection molded onto the lower insulating component to form the lower terminal module. Then, the upper and lower terminal modules are injection molded onto the insulating body a second time. Although this method can assemble the upper and lower terminals together, it requires two injection molding processes, necessitates the development of numerous injection molds, results in high design costs, and involves a complex process flow.

[0050] Please refer to Figures 1 to 9 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0051] A Type-C connector includes a shielding shell 10, an insulating body 20, an upper terminal group 30, an upper insulating component 40, a lower terminal group 50, a lower insulating component 60, and a latch 70. The shielding shell 10 covers the insulating body 20. The upper terminal group 30 is embedded and fixed on the upper insulating component 40 to form an upper terminal module, and the lower terminal group 50 is embedded and fixed on the lower insulating component 60 to form a lower terminal module. The upper terminal module and the lower terminal module are snapped together. The latch 70 is assembled between the upper terminal module and the lower terminal module to form a terminal latch module. This enables a modular snap-fit ​​assembly design of the upper and lower terminal modules, eliminating the need for two injection molding processes, simplifying the process flow, reducing the number of molds required, and saving manufacturing and design costs.

[0052] The insulating body 20 has a forward-facing insertion cavity 21. A plurality of terminal slots 22, arranged sequentially at intervals along a left-right direction, are recessed forward at the center of the rear end of the insulating body 20. The terminal slots 22 communicate with the insertion cavity 21. The front ends of the upper row of terminals of the upper terminal group 30 extend forward beyond the upper front side of the terminal hook module, and the front ends of the lower row of terminals of the lower terminal group 50 extend forward beyond the lower front side of the terminal hook module. Positioning grooves 23 are recessed forward on both the left and right sides of the rear end of the insulating body 20. The positioning groove 23 is connected to the insertion cavity 21. The hook 70 has hook portions 71 on both sides, and the hook portions 71 extend forward from the front side of the terminal hook module. The terminal hook module is assembled from back to front to the rear end of the insulating body 20. The front end of the upper row of terminals of the upper terminal group 30 is inserted into the upper side of the terminal groove 22, and the front end of the lower row of terminals of the lower terminal group 50 is inserted into the lower side of the terminal groove 22. The hook portions 71 are inserted into the positioning groove 23 and exposed in the insertion cavity 21.

[0053] The left and right sides of the rear end of the insulating body 20 are provided with positioning protrusions 24, and an insertion space 25 is formed between the two positioning protrusions 24. The terminal slot 22 and the positioning slot 23 are both connected to the insertion space 25. The left and right sides of the front end of the terminal hook module are provided with clearance slots 80. The front end of the terminal hook module is inserted into the insertion space 25 from back to front. The positioning protrusions 24 are positioned in the clearance slots 80. The inner sidewall of the positioning protrusions 24 is provided with protrusions 26, and the protrusions 26 contact the sidewall of the clearance slots 80. In this way, through the combined design of the positioning protrusions 24, the insertion space 25, the clearance slots 80 and the protrusions 26, the connection between the insulating body 20 and the terminal hook module is more secure.

[0054] The hook 70 has a base plate portion 72, and the two hook portions 71 are integrally connected to the left and right ends of the base plate portion 72 respectively. The base plate portion 72 has a first positioning hole 73 extending in the left and right direction. The lower surface of the upper insulating member 40 is provided with a receiving groove 44, and the upper surface of the lower insulating member 60 is provided with a first positioning block 64 extending in the left and right direction. The base plate portion 72 is assembled in the receiving groove 44, and the first positioning block 64 is positioned in the first positioning hole 73 so that the upper insulating member 40 and the lower insulating member 60 are assembled and positioned together by the first positioning block 64 and the first positioning hole 73. The first positioning block 64 extending in the left and right direction and the first positioning hole 73 can form a limit in the left and right direction to prevent the upper insulating member 40 and the lower insulating member 60 from moving relative to each other in the left and right direction.

[0055] The upper surface of the lower insulating member 60 is provided with second positioning blocks 65 extending in the front-back direction on both the left and right sides of the first positioning block 64. The lower surface of the upper insulating member 40 is provided with second positioning holes 45 extending in the front-back direction on both the left and right sides of the receiving groove 44. The second positioning blocks 65 are positioned in the second positioning holes 45 so that the upper insulating member 40 and the lower insulating member 60 are assembled and positioned together through the second positioning blocks 65 and the second positioning holes 45. The second positioning blocks 65 extending in the front-back direction and the second positioning holes 45 can form a limit in the front-back direction to prevent the upper insulating member 40 and the lower insulating member 60 from moving relative to each other in the front-back direction.

[0056] The second positioning block 65 has protrusions 651 extending in the vertical direction on both the left and right sides, so that the fit between the second positioning block 65 and the second positioning hole 45 is more secure, and it is more conducive to the secure fastening between the upper terminal module and the lower terminal module.

[0057] The lower surface of the upper insulating member 40 is provided with an upper limit wall 46 extending in the left-right direction on the rear side of the receiving groove 44. The rear side of the upper limit wall 46 is provided with a relief groove 47 extending in the left-right direction. The upper surface of the lower insulating member 60 is provided with a lower limit wall 66 extending in the left-right direction on the rear side of the first positioning block 64. The upper end of the lower limit wall 66 extends into the relief groove 47. The rear end face of the upper limit wall 46 abuts against the front end face of the lower limit wall 66. In this way, the relative movement of the upper insulating member 40 and the lower insulating member 60 in the front-back and left-right directions can be further restricted by the combined design of the upper limit wall 46, the lower limit wall 66, and the relief groove 47.

[0058] The upper surface of the rear end of the upper insulating member 40 is recessed with a buckle groove 48. The rear end of the shielding shell 10 is concave on the outside and convex on the inside, forming a buckle 11 inside the shielding shell 10. The buckle 11 is fastened and fixed with the buckle groove 48, so that the connection between the shielding shell 10 and the terminal hook module is more stable. In addition, the left and right sides of the rear end of the shielding shell 10 are provided with downward protruding pins 12 to facilitate the overall insertion and positioning of the connector.

[0059] The upper terminal group 30 has several upper-row terminals arranged side-by-side with spacing along the left-right direction. The upper surface of the upper insulating member 40 has a first upper through-hole group, an upper through-slot 41, and a second upper through-hole group arranged sequentially with spacing along the front-back direction. The first upper through-hole group includes several first upper through-holes 42 arranged side-by-side with spacing along the left-right direction, and the second upper through-hole group includes several second upper through-holes 43 arranged side-by-side with spacing along the left-right direction. The upper through-slot 41 extends in the left-right direction, and the lower ends of the first upper through-holes 42, second upper through-holes 43, and upper through-slot 41 all extend to the upper surface of the upper-row terminals. Here, the combined design of the first upper through-hole group, upper through-slot 41, and second upper through-hole group facilitates heat dissipation of the upper-row terminals, avoiding the problem of excessive temperature.

[0060] The lower terminal group 50 has several lower terminals arranged side-by-side with spacing in the left-right direction. The lower surface of the lower insulating member 60 has a first lower through-hole group, a lower through-groove 61, and a second lower through-hole group arranged sequentially with spacing in the front-back direction. The first lower through-hole group includes several first lower through-holes 62 arranged side-by-side with spacing in the left-right direction, and the second lower through-hole group includes several second lower through-holes 63 arranged side-by-side with spacing in the left-right direction. The lower through-groove 61 extends in the left-right direction, and the upper ends of the first lower through-holes 62, second lower through-holes 63, and lower through-groove 61 all extend to the lower surface of the lower terminal group. Here, the combined design of the first lower through-hole group, lower through-groove 61, and second lower through-hole group facilitates heat dissipation of the lower terminal group and avoids the problem of excessive temperature.

[0061] In summary, the key design feature of this utility model lies in its method of embedding and fixing the upper terminal group onto the upper insulating component to form an upper terminal module, and embedding and fixing the lower terminal group onto the lower insulating component to form a lower terminal module. The upper and lower terminal modules are then interlocked together, with hooks assembled between them during interlocking to form a terminal hook module. This achieves a modular interlocking assembly design for the upper and lower terminal modules, eliminating the need for two injection molding processes, simplifying the process flow, reducing the number of molds required, and saving on manufacturing and design costs.

[0062] 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.
