[0034] In one embodiment, the base 11, the workbench 12 and the support portion 13 are all integrally formed. In another embodiment, the workbench 12 is mounted on the support portion 13.

[0038] See also Figure 3 The above-mentioned press-fitting device also includes a press head assembly 5 connected to the press rod 4. By replacing the press head assembly 5, different electrical connectors can be further adapted. Furthermore, the press head assembly 5 includes a first press head 51 and a second press head 52 fixedly connected to each other, and the first press head 51 is fixedly connected to one end of the press rod 4 close to the base 11 through a fastener. The first press head 51 is preferably made of a metal material with a certain hardness such as steel, and the second press head 52 is preferably made of a material with a certain elasticity and flexibility such as polyurethane. When contacting the electrical connector, the first press head 51 ensures pressure while the second press head 52 plays a certain buffering role to prevent excessive pressure from fracturing the electrical connector.
[0039] In one embodiment, the second pressing head 52 can be fixed to the end of the first pressing head 51 close to the base 11 by adhesive bonding or other connection methods in the prior art.

Optionally, the press-fitting device further comprises a digital display switch electrically connected to the pressure sensor 8, which is used to display the pressure applied by the press head assembly 5 in real time during the press-fitting process, and to issue a reminder when the pressure exceeds the set range, so as to further avoid fracturing the electrical connector.
[0041] During press-fitting, the driving member 3 drives the transmission member 2 to rotate, driving the pressure rod 4 to move relative to the workbench 12 toward the base 11. When the second pressure head 52 contacts the surface of the electrical connector, as the pressure rod 4 continues to move, the second pressure head 52 abuts against the electrical connector. Since the second pressure head 52 is made of elastic and flexible materials such as polyurethane, the second pressure head 52 is deformed and abuts against the pressure sensor 8, thereby monitoring the pressure on the second pressure head 52 in real time, that is, the pressure applied to the electrical connector. When the pressure exceeds the set range, an alarm is issued through a digital display switch, etc., to prevent the electrical connector from being fractured.
