Here, when the mover is used, the first end portion 1 of the mover is used for being mounted on an electrical connector and connected with a conducting wire, specifically, one end of the first end portion 1 can be connected with the electrical connector through a thread arranged on the body of the first end portion 1; the pin 11 is disposed at the other end of the first end portion 1, and the pin 11 and the first end portion 1 constitute a movable contact pin. The second end portion 2 is a jack body, and the jack hole 21 is formed in the second end portion 2.

As shown in fig. 1, the aperture of the pin hole 21 of the second end portion 2 is provided with a closing plate 22, the pin rod 11 provided on the first end portion 2 is inserted into the pin hole 21 of the second end portion 2 through the closing plate 22, and the pin rod 11 can move along the axial direction of the pin hole 21, where the closing plate 22 is a plate material (e.g. a metal plate) with certain elasticity and has a closing effect on the aperture of the pin hole 21, so that when the pin rod 11 enters the pin hole 21, the clamping force of the closing plate 22 is certainly applied to the pin rod 11 when the pin rod enters the pin hole 21, and the movement of the pin rod 11 in the pin hole 21 is stabilized.

Further, the contact surface of the closing plate 22 for the shank 11 is smooth, so that the friction force between the shank 11 and the shank can be reduced.

Further, as shown in fig. 2, in the embodiment of the present invention, there are more than two closing plates 22, and the closing plates 22 are circumferentially disposed along the aperture edge of the pin hole 21; the closing plate 22 is an arc-shaped elastic plate, wherein the inner arc surface of the closing plate 22 is attached to the surface of the shank of the needle inserting shank 11.

Here, as shown in fig. 2, the closing plate 22 has four pieces, and the four pieces of the closing plate 22 form a tubular structure around the opening of the needle inserting hole 21, a gap exists between any two adjacent pieces of the closing plate 22, and the inner arc surface of each piece of the closing plate 22 is attached to the shank surface of the needle inserting shank 11, so that the contact area of the closing plate 22 and the needle inserting shank 11 is increased, and the stability of the use of the needle inserting shank 11 is ensured.

Further, as shown in fig. 1, in the embodiment of the present invention, an elastic device 3 is disposed between the first end portion 1 and the second end portion 2, wherein one acting end of the elastic device 3 is connected to the first end portion 1, and the other acting end of the elastic device 3 is connected to the second end portion 2; the elastic device 3 is sleeved with a sleeve 4, and two ends of the sleeve 4 are respectively connected with the first end part 1 and the second end part 2.

Here, the elastic device 3 is disposed between the first end portion 1 and the second end portion 2, and generates an axial elastic force to the first end portion 1 and the second end portion 2. As shown in the figures, said elastic means 3 may be a spring; in this way, when the spring (the elastic device 3) is installed, one end of the spring (the elastic device 3) is clamped on the first end portion 1 through a first boss arranged on the first end portion 1, and the other end of the spring (the elastic device 3) is clamped on the second end portion 2 through a second boss arranged on the second end portion 2, and then the sleeve 4 is matched, so that the spring (the elastic device 3) moves along the axial direction, and the possibility of radial displacement of the spring (the elastic device 3) is limited.

Meanwhile, when the spring (the elastic device 3) is displaced radially due to deformation or the like caused by long-term use, the closing plate 22 can protect the plunger 11, and the spring (the elastic device 3) is prevented from damaging the plunger 11.

Further, as shown in fig. 1, in the embodiment of the present invention, a first protrusion 23 is disposed on an outer surface of the second end portion 2, a second protrusion 41 is disposed on an inner surface of the sleeve 4, and the second end portion 2 is connected to the sleeve 4 by engaging the first protrusion 23 with the second protrusion 41.

A cushion pad 5 is disposed between the first protrusion 23 and the second protrusion 41.

The first end portion 1 is connected to the sleeve 4 by a pin 6.

Here, since the sleeve 4 is sleeved on the elastic device 3, the fixation of the sleeve 4 is facilitated, and the problem that the first end portion 1 is separated from the second end portion 2 due to the action of the elastic device 3 is avoided. During installation, as shown in fig. 1, pin holes are formed in both one end of the sleeve 4 and the first end portion 1, and the sleeve 4 is connected to the first end portion 1 through one of the pins 6. The second protrusion 41 is circumferentially arranged along the inner surface of the other end of the sleeve 4, and the second protrusion 41 is annular and can be integrally formed with or detachably connected with the sleeve 4; the first protrusion 23 is circumferentially arranged along the outer surface of the second end portion 2, and the first protrusion 23 is annular and can be integrally formed with or detachably connected with the second end portion 2; when the connector is installed, the first protrusion 23 is clamped with the second protrusion 41 by the elastic force of the elastic device 3, and the second protrusion 41 prevents the first end portion 1 and the second end portion 2 from being separated due to the elastic force of the elastic device 3 on the first end portion 1 and the second end portion 2, so that the connection stability of the first end portion 1 and the second end portion 2 is protected.

Due to the action of the elastic means 3, the first protrusion 23 is acted upon by the elastic force of the elastic means 3 and acted upon by the second protrusion 41 after each use of the mover, and in order to avoid that the first protrusion 23 and the second protrusion 41 interact with each other after a long time of use and reduce the service life, the buffer pad 5 is disposed between the first protrusion 23 and the second protrusion 41. Here, the buffer pads 5 may be provided on the first protrusions 23, the buffer pads 5 may be provided on the second protrusions 41, or the buffer pads 5 may be provided on the first protrusions 23 and the second protrusions 41, respectively; in use, the cushion pad 5 may be made of high temperature resistant flame retardant fibers.
