[0037] In some embodiments, the diameter of the third portion 230 is D3, and D3>D2. For example, D3 may be 1.1*D2, 1.2*D2, or 1.3*D2.

[0039] By making the diameter D1 of the first part 210 and the diameter S1 of the first through hole 2011 satisfy 0.05mm≤S1-D1≤0.15mm, the axis center of the first part 210 and the axis center of the first through hole 2011 can be closer or coaxially arranged, so that the position of the bushing 202 pressed into the first through hole 2011 can be more accurate and the assembly effect of the bushing 202 and the shell 201 is better.

[0040] In some embodiments, the diameter of the second portion 220 is D2, the diameter of the second through hole 2021 is S2, and 0.05 mm ≤ S2 - D2 ≤ 0.15 mm. For example, S2 - D2 may be 0.05 mm, 0.1 mm, or 0.15 mm.

[0041] By making the diameter D2 of the second part 220 and the diameter S2 of the second through hole 2021 satisfy 0.05mm≤S2-D2≤0.15mm, the axis center of the first part 210 and the axis center of the first through hole 2011 can be made closer or coaxially arranged, so that the position of the bushing 202 pressed into the first through hole 2011 can be more accurate and the assembly effect of the bushing 202 and the shell 201 is better.

[0042] In some embodiments, the base 100 is provided with a second accommodating cavity 102, the second accommodating cavity 102 forms an opening on the first surface 110, the second accommodating cavity 102 is used to accommodate the main body 2012 of the shell 201, the first surface 110 is used to support the protrusion 2013 of the shell 201, and the first through hole 2011 is provided on the protrusion 2013.

[0044] See also Figure 7 , Figure 7 A schematic three-dimensional structure diagram of a punch of a connector preparation device provided in some embodiments of the present application.

[0045] In some embodiments, the punch 400 includes a body 410 and a boss 420 . The boss 420 is disposed on a side of the body 410 facing the base 100 . Along the first direction X, a projection of each boss 420 overlaps with a projection of a guide post 200 .

[0046] By making the punch 400 include a main body 410 and a boss 420, the boss 420 is arranged on the side of the main body 410 facing the base 100, and along the first direction X, the projection of each boss 420 overlaps with the projection of a guide column 200, so that the boss 420 can act on the guide column 200 and apply a force along the first direction X to the guide column 200, thereby compressing the elastic member 300 and moving the guide column 200 downward.

[0047] In some embodiments, the diameter of the protrusion 420 is less than or equal to the diameter of the second portion 220 .

[0048] By making the diameter of the boss 420 smaller than or equal to the diameter of the second portion 220, the boss 420 acts on the guide column 200 instead of the bushing 202. The boss 420 presses the guide column 200 downward and penetrates into the bushing until the main body 410 of the punch 400 abuts against the bushing 202. In the process of the main body 410 pressing the bushing 202 into the shell 201, the elastic member 300 generates a large force, which acts as a buffer and reduces the possibility of damage to the bushing 202 and the shell 201 caused by rapid punching.

[0049] In some embodiments, a clearance groove 401 is disposed on a side of the punch 400 facing the base 100 .

[0050] By providing a clearance groove 401 on the side of the punch 400 facing the base 100 , it can avoid other components (not shown in the figure) on the housing 201 , thereby reducing the possibility of the punch 400 damaging the connector 20 .

[0051] In some embodiments, the connector manufacturing device 10 includes a base 500, the base 100 is disposed on the base 500, and the base 100 and the base 500 are detachably connected.

[0052] By making the connector preparation device 10 include a base 500, the base 100 is arranged on the base 500, and the base 100 and the base 500 are detachably connected, different bases 100 can be replaced for different connectors 20, so that the connector preparation device 10 has a wider range of application.

[0053] In some embodiments, the connector preparation device 10 includes a fixing member (not shown in the figure), the base 100 is provided with a threaded hole 103, the fixing member has an external thread, the fixing member is threadedly connected to the threaded hole 103, and one end of the fixing member along the first direction X is abutted against the base 500.

[0054] By making the connector preparation device 10 include a fixing part, the base 100 is provided with a threaded hole 103, the fixing part has an external thread, the fixing part is threadedly connected to the threaded hole 103, and one end of the fixing part along the first direction X is abutted against the base 500, so that by adjusting the ejection height of the fixing part, the parallelism of the press-fit plane of the base 100 and the punch 400 can be adjusted, so that the press-fit consistency of the connector 20 is higher.
