As shown in fig. 2, in the present embodiment, the axial pushing member is a spring plate 11, the spring plate 11 includes a spring plate base body and a spring claw, the spring plate base body is a tubular member parallel to the axis, the spring claw is a claw-shaped member whose root is fixed to the spring plate base body and is independent of each other, and a main body portion of the spring claw has a taper and is gradually biased toward the axis. During assembly, the spring base is clamped on the inner wall of the through hole of the insulator. In other embodiments, the axial pushing member may adopt the positioning pawl in the background art.
As shown in fig. 3 and 4, the pin contact 2 is manufactured by a stamping process, and includes a pin insertion section 21, a pin positioning stage 22, a conductive connection structure, a front positioning portion including a front positioning outer circumferential surface 23, and a rear positioning portion including a rear positioning outer circumferential surface 24.
The contact pin inserting section 21 is located at the front part of the contact pin contact element 2, the section of the contact pin inserting section 21 is circular, the head part of the contact pin inserting section 21 is provided with an arc surface, and the head part of the contact pin inserting section 21 with the arc surface can guide the inserting process of the contact pin contact element 2 and the jack contact element, so that the inserting process of the contact pin contact element and the jack contact element is smoother.
The pin positioning table 22 is arranged behind the pin inserting section 21, the pin positioning table 22 is a cylindrical table, the diameter of the pin positioning table 22 is larger than that of the pin inserting section 21, the connecting pipe 23 is arranged behind the pin positioning table 22, and the diameter of the connecting pipe 25 is smaller than that of the pin positioning table 22.
The pin inserting section 21 is a front positioning part of the pin contact element 2, a partial outer peripheral surface of the pin inserting section 21 forms a front positioning outer peripheral surface 23, specifically, after the pin contact element 2 is inserted into the insulator through hole, the partial outer peripheral surface of the pin inserting section 21 close to the pin positioning table 22 is attached to the hole wall of the insulator through hole, and the outer peripheral surface of the attached part forms the front positioning outer peripheral surface 23.
The end surface of the pin positioning table 22 away from the pin insertion section 21 is a press-fit surface 26, and when the pin contact 2 is installed in the through hole of the insulator of the plug connector, the spring claws of the spring pieces 11 press and push the press-fit surface 26 on the pin positioning table 22 forward to prevent the pin contact 2 from being withdrawn from the plug connector.
In this embodiment, the conductive connection structure is a wire pressing groove 27 for pressing the wire, the wire pressing groove 27 is a U-shaped groove and is disposed behind the connection pipe 25, and two groove side walls of the wire pressing groove 27 can be deformed and bent after being pressed to press the wire.
The connecting section 28 is arranged at the bottom of the line pressing groove 27, and a rear positioning portion is connected to the rear of the connecting section 28, in this embodiment, the rear positioning portion is a positioning ring 29, the positioning ring 29 is a C-shaped structure with an opening, the opening of the positioning ring 29 and the opening of the line pressing groove 27 face in the same direction, the outer peripheral surface of the positioning ring 29 forms a rear positioning outer peripheral surface 24, and both the front positioning outer peripheral surface 23 and the rear positioning outer peripheral surface 24 are cylindrical surfaces.
Because holding ring 29 and wire pressing groove 27 all have the opening and two open-ended orientations are unanimous, consequently can more conveniently put into wire pressing groove 27 to the wire edgewise, and then conveniently utilize line ball equipment to carry out automatic line ball in batches to improve line ball efficiency.
The axis of the insulator through hole where the positioning ring 29 is located coincides with the axis of the insulator through hole where the pin inserting section 21 is located, and therefore, in order to enable the pin contact 2 to be smoothly inserted into the insulator through hole, the connecting section 28 extends outward from the front to the rear in the radial direction of the rear positioning outer peripheral surface 24 so as to facilitate the coaxial arrangement of the front positioning outer peripheral surface 23 and the rear positioning outer peripheral surface 24, and specifically, the connecting section 28 is obliquely arranged.

Therefore, the pin contact 2 is supported in the radial direction by the hole walls of the insulator through holes that are fitted to the two positioning outer peripheral surfaces, and even if the wire pressed into the wire-pressing groove 27 radially shakes, the entire pin contact 2 is less likely to deflect.
During assembly, a wire is firstly placed into the wire pressing groove 27 of the pin contact element 2 from the side, then pressure is applied to two groove side walls of the wire pressing groove 27 until the groove side walls deform and bend and press the wire, then the spring piece 11 is installed into the through hole of the insulator, and then the pin contact element 2 is inserted into the corresponding hole of the insulator.
When inserting the pin contact 2, the pin insertion section 21 passes through the spring plate 11 first, then the pin positioning table 22 starts to enter the spring plate 11, because the diameter of the pin positioning table 22 is large, the spring claw can be spread when the pin positioning table 22 passes through the spring claw of the spring plate 11, when the pin positioning table 22 completely passes through the spring claw, the spring claw recovers to the original state and the top of the spring claw is pressed on the top pressing matching surface 26, at this time, the pin contact 2 is inserted in place, the front positioning outer peripheral surface 23 is attached to the hole wall of the insulator through hole where the pin insertion section is located, the rear positioning outer peripheral surface 24 of the positioning ring 29 is attached to the hole wall of the insulator through hole where the positioning ring 29 is located, and the two attaching parts support the pin contact 2 radially together.
