Embodiment 1

[0027] This embodiment provides a connection terminal, which is made of sheet metal material, and includes a connection terminal 1 and a connection terminal connected with other parts. Such as image 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the terminal 1 has a through hole 11 for wiring; the connection end includes a cylinder 3 extending outward from the terminal 1, and the inner wall of the cylinder 3 has an inner wall. The thread forms a threaded hole 4, and the connection terminal is connected to other parts through the threaded hole 4, for example, connected to other parts by means of screws.

[0028] The terminal block can be used in places where wiring is required in electronic products, such as in mobile phones, as a connector for connecting the battery of the mobile phone to the conductor.

[0029] Such as image 3 and Figure 4 As shown, in another preferred embodiment of the present invention, the length L of the cylindrical ...

Embodiment 2

[0031] This embodiment provides a method for processing threaded holes on sheet metal parts. In a preferred embodiment of the present invention, it includes the following steps:

[0032] A. If figure 1 and figure 2 As shown, the lug 2 is integrally formed at the place where the threaded hole 4 needs to be added on the sheet metal part;

[0033] B. If image 3 As shown, the lug 2 is bent into a cylinder 3;

[0034] C. Tapping threads on the inner wall of the cylinder 3 to obtain threaded holes 4 .

[0035] In this embodiment, the number of lugs 2 is one or two; figure 1 As shown, when the number of lugs 2 is one, it is located on one side of the threaded hole 4 (the side where the threaded hole 4 needs to be added); figure 2 As shown, when the number of lugs 2 is two, the two lugs 2 are arranged symmetrically on both sides of the threaded hole 4 . Compared with the structure of one lug 2 , two lugs 2 reduce the difficulty of bending into a cylindrical tube 3 .

Abstract

The invention provides a method for machining a threaded hole in a sheet metal part. The method comprises the following steps that A, a supporting lug is integrally formed in the position, where the threaded hole needs to be additionally formed, of the sheet metal part; B, the supporting lug is bent into a cylinder; and C, a thread is tapped on the inner wall of the cylinder to obtain a threaded hole. According to the technical scheme, the supporting lug is reserved on the sheet metal part, bent into the cylinder with a certain length, and then tapped and machined into the required threaded hole. On a sheet metal part with certain structural condition limitation, the threaded hole obtained through the method has enough thread turns, so the wiring terminal can be reliably connected with other parts.

Description

technical field [0001] The invention belongs to the field of electronic product processing, and in particular relates to a method for processing threaded holes on a sheet metal part and the sheet metal part. Background technique [0002] Sheet metal parts are widely used in the structural design of electronic products, and usually need to be connected with other parts by screws to play a fixed role. The usual thread tapping method for sheet metal parts is: punch a bottom hole in the vertical direction of the sheet metal thickness, then punch the flanging to form a through hole with a height of about 1.5T (T is the thickness of the sheet metal), and tap in the through hole after heating. The wire forms a threaded hole. The threaded holes processed on the sheet metal parts by the above method, due to the limited height of the threaded holes, the number of thread turns is not enough, and the fixing strength is limited when connecting with other parts.
