[0001] The utility model relates to the fields of terminal connectors and rail transportation, and in particular to a special-shaped stud structure for increasing embedding reliability. Background Art
[0002] With the popularity of electronic devices, stud terminals have become an important tool for connecting circuit components and power supplies. They conduct current in the forward direction and are connected as loads in the loop. Stud terminals can not only quickly connect circuits, but also replace circuit boards quickly and easily. With the continuous advancement of technology, stud terminals used in electronic products have also been continuously developed to meet the needs of different products.
[0003] In general, stud terminals play a very important role in electronic products. In the process of continuous development, stud terminals have also made great progress and improvement. With the continuous advancement of science and technology, stud terminals have been continuously improved in terms of manufacturing materials, shape and size, operation and use, etc., which has improved the convenience, reliability and safety of operation. In the future, with the continuous development of various electronic products, the demand for stud terminals will also be more diversified. Therefore, enterprises need to keep up with the market demand, lead the development direction of stud terminals, and contribute to the industry.
[0004] When the product structure is compact, ordinary studs are buried in the plastic shell, which may cause the studs to loosen and the torque to fail to meet the actual requirements when the nuts are tightened. Utility Model Content
[0005] In view of the problems existing in the prior art, the utility model provides a special-shaped stud structure for increasing embedding reliability, so as to solve at least one of the above-mentioned technical problems.
[0006] The technical solution of the utility model is: a special-shaped stud structure for increasing embedding reliability, comprising a stud structure embedded in a plastic shell body, characterized in that the stud structure comprises a head end and a column body, and the column body is connected to the upper surface of the head end;
[0007] The head end is a cylindrical structure, the outer wall of the head end is provided with at least two cutting planes, the two cutting planes are arranged oppositely on the outer wall of the head end, the lower surface of the head end is provided with two columns, the columns are arranged at intervals on the lower surface of the head end, and the surface of the columns is provided with knurling;
[0008] The head end is buried in the plastic shell body, the installation direction of the column is toward the inside of the plastic shell body, and the installation direction of the column body is toward the outside of the plastic shell body.
[0009] The utility model adds a plane on the surface of the head end and wraps it with injection molding material, which is conducive to the stud not being easy to rotate on the horizontal plane and improves the torque; adding knurling on the surface of the column is conducive to the vertical surface not being easy to pull out and improves the pulling force.
[0010] Further preferably, the front and rear sides of the column are flat surfaces, and the front and rear sides are connected by an arc surface, thereby increasing the torque.
[0011] Further preferably, the height of the column is consistent with the height of the head end.
[0012] Thereby ensuring convenient processing and stability during installation.
[0013] Further preferably, the bottom edge of the head end is rounded.
[0014] This allows the external space to be made smaller and the product is less likely to discharge electrically.
[0015] Further preferably, the surface of the column body is provided with threads, and the lower end of the column body is buried in the plastic shell body.
[0016] The embedding strength can be improved by the thread structure.
[0017] Further preferably, there are four cutting planes, and the four cutting planes are evenly arranged on the outer wall of the head end. Four planes are cut on the circular surface, so that the horizontal plane is not easy to rotate, and the torque is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] like Figure 1-Figure 2As shown, a special-shaped stud structure for increasing embedding reliability includes a stud structure embedded in a plastic shell body, the stud structure includes a head end 1 and a column body 2, the column body is connected to the upper surface of the head end; the head end is a cylindrical structure, the outer wall of the head end is provided with at least two cutting planes 3, the two cutting planes are relatively arranged on the outer wall of the head end, the lower surface of the head end is provided with two columns 4, the columns are arranged at intervals on the lower surface of the head end, and the surface of the column is provided with knurling 5; the head end is embedded in the plastic shell body, the installation direction of the column is toward the inside of the plastic shell body, and the installation direction of the column body is toward the outside of the plastic shell body. The utility model increases the plane on the surface of the head end through the wrapping of the injection molding material, which is conducive to the stud not being easy to rotate on the horizontal plane and improving the torque; adding knurling on the surface of the column is conducive to not being easy to pull out on the vertical plane and improving the pulling force.
[0023] Further preferably, the front and rear sides of the column are flat, and the front and rear sides are connected by an arc surface, thereby increasing the torque.
[0024] Preferably, the height of the column is consistent with the height of the head end, thereby ensuring stability during installation and convenience of processing.
