Technical Field

[0001] The utility model relates to the field technology of Type C connector shells, in particular to a Type C connector shell that is easy to assemble. Background Art

[0002] Type-C is much smaller than Type-A and Type-B, and is a new type of USB interface with a light, thin and compact interface. In addition, Type-C is an interface type that can be used for both PCs (master devices) and external devices (slave devices, such as mobile phones), and has good practicality. Type-C also supports higher power transmission, up to 100W, and the fastest data transmission speed is up to 10Gbps, supporting more high-power load devices. In addition, Type-C is the latest USB interface appearance standard. This interface has no difference in forward and reverse directions and can be plugged in and out at will, making it more flexible to use. Type-C connectors have many specifications and types, including 6-pin, 12-pin, 16-pin, and 24-pin structures. Type-C connectors often involve a connector shell, which mainly fixes the connector and external parts, making the connection structure more stable and providing mechanical protection.

[0003] In the prior art, such as Figure 6 As shown, some Type C connector shells are provided with a left extension portion 21' and a right extension portion 22' on the left and right sides of the main body 10'. The left extension portion 21' is connected to the left folding portion 31' through the left connecting portion 41', and the right extension portion 22' is connected to the right folding portion 32' through the right connecting portion 42'. The left folding portion 31' is folded and folded onto the upper surface of the left extension portion 21', and the right folding portion 32' is folded and folded onto the upper surface of the right extension portion 22'. The extension direction of the left connecting portion 41' and the right connecting portion 42' is perpendicular to the extension direction of the main body 10'. This Type The structural design of the C connector housing is not very reasonable. It has high requirements for the dimensions of the stamping process and the folding process. After the left folding part 31' and the right folding part 32' are folded, they often protrude slightly due to processing reasons, making it difficult to install the connector into the housing. The defect rate is high and rework is required, which affects the quality of the product and brings inconvenience to production. In addition, due to the long length of the housing, the step distance is large during stamping production, resulting in a long stamping mold design and the design of the automatic machine line in the back stage. The mold and automatic machine are difficult to design, the production efficiency is low, the production space is wasted, the manufacturing cost is high, and it cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0038] The main body 10 is extended left and right, and is provided with a mounting cavity 101 for mounting a connector. In this embodiment, through holes 11 are formed through the upper and lower surfaces of the main body 10. Specifically, the through holes 11 are square, and there are two through holes 11, which are symmetrically arranged left and right. The main body 10 is concave at the top and convex at the bottom, thereby forming ridges 12 on the lower surface. Specifically, there are six ridges 12, and every three ridges 12 are arranged on the left and right sides of the main body 10, and every three ridges 12 are evenly spaced longitudinally.

[0039] The two extensions 20 extend outwardly from the left and right sides of the main body 10, and a first fixing hole 21 is formed through the upper and lower surfaces of each extension 20; in this embodiment, the first fixing hole 21 is circular; the extension 20 is concave at the top and convex at the bottom, thereby forming a first protrusion 22 on the lower surface; specifically, there are three first protrusions 22, and the three first protrusions 22 are arranged at intervals around the circumference; a first fixing foot 23 extends from one side of the extension 20 for fixed connection with an external part.

[0040] The two folding portions 30 are respectively arranged on the upper surfaces of the corresponding extension portions 20 by folding and folding, and a second fixing hole 31 is formed through the upper and lower surfaces of each folding portion 30, and the second fixing hole 31 is communicated with the first fixing hole 21. The second fixing hole 31 and the first fixing hole 21 are used for fixing with external parts, and the upper surface of the folding portion 30 is provided with a plurality of welding points 32 formed by spot welding. The spot welding method makes the connection structure of the folding portion 30 and the extension portion 20 more stable and reliable, and simple to operate; in this embodiment, the second fixing hole 31 is circular; the folding portion 30 is convex on the upper side and concave on the lower side, thereby forming a second convex point 33 on the upper surface; specifically, there are three second convex points 33, and the three second convex points 33 are arranged at intervals around the circumference, and the three second convex points 33 correspond to the positions of the three first convex points 22; a second fixing foot 34 extends from one side of the folding portion 30 for fixed connection with external parts.

[0041] The two connecting portions 40 are respectively disposed between the corresponding extending portion 20 and the folding portion 30 and connect the corresponding extending portion 20 and the folding portion 30 . The extending direction of the two connecting portions 40 is the same as the extending direction of the main body 10 .

[0042] The production process of this embodiment is described in detail as follows:

[0043] First, a metal sheet is placed in a mold and stamped to obtain a semi-finished shell; then, the two folding parts 30 are folded along the corresponding connecting parts 40, so that the two folding parts 30 are respectively overlapped and arranged on the upper surface of the corresponding extending part 20, and the second fixing hole 31 is connected to the first fixing hole 21 (because the direction in which the connecting part 40 extends is the same as the direction in which the main body 10 extends, the two folding parts 30 will not affect the installation cavity 101 after folding, and will not protrude into the installation cavity 101); finally, a plurality of welding points 32 are formed on the upper surface of the two folding parts 30 by spot welding.

[0044] During assembly, the shield shell 51 of the connector 50 is placed into the mounting cavity 101 of the Type C connector housing for installation. The housing and the shield shell are then connected by spot welding. This is quick and easy to operate, and the housing and the shield shell fit together perfectly. The shield shell will not be unable to fit into the mounting cavity 101 due to protrusion of the folded portion 30 due to poor pre-processing. This eliminates the need for rework, thus facilitating production.

[0045] The design focus of this utility model is:

[0046] The two extension parts are formed by extending outward on the left and right sides of the main body, and the upper and lower surfaces of each extension part are penetrated with a first fixing hole, and the two folding parts are respectively folded and folded to be set on the upper surface of the corresponding extension part. The upper and lower surfaces of each folding part are penetrated with a second fixing hole, and the second fixing hole is connected to the first fixing hole. A plurality of welding points formed by spot welding are provided on the upper surface of the folding part, and the two connecting parts are respectively provided between the corresponding extension part and the folding part and connect the corresponding extension part and the folding part. The extension direction of the two connecting parts is the same as the extension direction of the main body. This type of structure The C connector shell improves the previous structure in which the connecting portion extending in a direction perpendicular to the main body extending direction into a structure in which the connecting portion extending in the same direction as the main body extending direction. When the folding portion is folded, the folding portion does not protrude, and the connector can be smoothly installed in the shell. The assembly is convenient and quick. The stamping process and the folding process have little impact on the shell, which greatly reduces the defective rate and does not require rework, thereby improving product quality and bringing convenience to production. In addition, the length of the shell can be effectively reduced, the step distance can be reduced during stamping production, and the stamping mold design and the post-automatic automatic machine line design can be shortened, reducing the difficulty of the mold and automatic machine, improving production efficiency, saving production space, reducing manufacturing costs, and meeting existing needs.
