Description

Technical Field

[0001] The utility model relates to the field technology of fisheye terminals, in particular to a fisheye terminal with improved deformation defects. Background Art

[0002] Fisheye terminals are widely used in the connection of PCB boards. Fisheye terminals usually include a fisheye terminal body, which includes a fisheye plug-in portion, a supporting portion, a bending portion, and a patch board portion that are sequentially connected from top to bottom; the fisheye plug-in portion forms a good connection with the conductive socket of the PCB board after insertion and will not easily fall out of the conductive socket, making the connection with the conductive socket of the PCB board more firm and the signal transmission more reliable; the bending portion is used to provide a certain buffer force when the terminal is squeezed to avoid damage caused by excessive pressure when the PCB board is pressed down.

[0003] In actual use, especially when plugging, there may be excessive extrusion, and the bending amplitude of the bending part is too large, causing plastic deformation, which will make it difficult for the fisheye terminal as a whole to form reliable support. Based on this, the industry has proposed some solutions. For example, CN 112615179 A discloses a fisheye terminal, including a main body and a plug part arranged at the end of the main body. The plug part is a symmetrical four-leg structure with folded ends, and the legs of the four-leg structure are all curved. When the plug part is inserted into the PCB hole, the outer arc surface of the legs of the four-leg structure presses against the inner wall of the PCB hole. At the same time, a limit block for limiting the deformation amplitude of the bending part is fixedly arranged in the concave surface of the bending part, and the top of the bending part is arranged above the free end of the limit block. In this way, when the bending part deforms downward to a certain extent, it will be limited by the limit block.

[0004] However, the structure of this fisheye terminal is relatively complex and it is troublesome to produce. Therefore, the applicant has studied a fisheye terminal with a simple structure, easy to produce and prevent deformation, and ensure reliable support and connection. Utility Model Content

In addition, its structure is simple and ingenious, and its production method is simple and easy to produce.
