Description

Technical Field

[0001] The present application relates to a socket connector. Background Art

[0002] USB 3.1 is the latest USB specification, which was initiated by Intel and other large companies. The data transmission speed can be increased to 10Gbps. Compared with the traditional USB 2.0 technology, the new USB technology uses a more efficient data encoding system and provides more than double the effective data throughput. USB 3.1 includes three types: Type-A, Type-B and Type-C. In December 2013, the USB 3.0 promotion team announced the rendering of the next-generation USB Type C connector, and then in August 2014, it was ready for mass production. The highlights of the new version of the connector are a slimmer design, faster transmission speed and more powerful power transmission. The biggest advantage is that it supports front and back plugging, which solves the problem of "USB can never be plugged in correctly".

[0003] In the prior art, such as the patent disclosure of CN111864458A, the ears on both sides of the upper and lower iron shells 24 and 25 are generally directly stacked and welded to the docking circuit board. Due to the thin thickness of the upper and lower iron shells 24 and 25, the structural strength is weak when the connector is installed in the whole machine and abuts against the body structure, and it is easy to deform, causing the product to shake during installation. It is impossible to effectively and accurately position.

[0004] In order to increase the thickness structure of the ear, the outer iron shell can be designed as a powder metallurgy structure or a die-casting structure, such as the prior art CN118431835A. However, other parts of the outer iron shell except the ear do not need such a thick structure. If the outer iron shell as a whole is designed as a powder metallurgy structure or a die-casting structure, the overall dimensions of the entire connector will be increased, especially the thickness and width of the entire connector. In addition, the manufacturing cost of the powder metallurgy structure or the die-casting structure itself is higher than that of the stamping parts.

[0005] Therefore, it is necessary to design a new solution to solve the above technical problems. Summary of the invention

[0006] The purpose of the present application is to provide a socket connector, which improves the overall structural strength of the first ear and the second ear, is not easy to deform, and makes the socket connector less likely to shake after being assembled into an electronic device, and the assembly positioning is accurate.

[0011] Furthermore, the side upright portion and the end upright portion are directly connected to form an integral whole, or the side upright portion and the end upright portion are connected to form an integral whole via an arc-shaped transition portion.

[0012] Furthermore, the upright portion is formed at the outer peripheral edge of the first main body portion and is arc-shaped along a cross section perpendicular to the up-down direction.

[0013] Furthermore, the upright portion includes a middle upright portion which is integrally formed at a middle position of the first main body portion or the second main body portion and extends in the up-down direction, and the middle upright portion is in a through cylindrical shape in the up-down direction.

[0014] Furthermore, the first main body or the second main body without forming a central upright portion has a through hole formed therethrough at a position corresponding to the central upright portion, and a free end of the central upright portion in the up-down direction is passed through and limited in the through hole.

[0015] Furthermore, the central upright portion abuts against a corresponding surface of the first main body portion or the second main body portion where the central upright portion is not formed, and the first main body portion or the second main body portion where the central upright portion is not formed is penetrated by a through hole in the up and down direction and connected to the central upright portion.

[0016] Further, the position of the first ear portion adjacent to the first covering portion is configured to have a margin for elastic deformation relative to the second ear portion in the up-down direction, and / or the position of the second ear portion adjacent to the second covering portion is configured to have a margin for elastic deformation relative to the first ear portion in the up-down direction.

[0017] Furthermore, the socket connector is a USB Type C socket connector.

[0018] Furthermore, the side upright portion and the end upright portion are integrally connected with the first main body portion by drawing and processing through a metal plate, and there is no connection gap between them.

[0019] Compared with the prior art, the beneficial effects of the present application are: improving the overall structural strength of the first ear and the second ear, making them less likely to deform, so that the socket connector is less likely to shake after being assembled into an electronic device, and the assembly positioning is accurate.
