The inner walls of the center and bottom of the ball-and-socket assembly have snap-fits a, and the inner walls of the sockets have snap-fits b.

[0006] The side wall of the card post is provided with a protruding strip, the opening of the terminal block matches the shape of the terminal, and the two sides of the terminal block are provided with blocks.

[0007] The lower ball socket assembly has inserts on both sides of the front part, inserts with holes in the middle, and the outer wall of the insert head has a slope. The middle part has a wall body in the shape of a racetrack, and the middle part of the wall body has a wire hole. The wire hole is a slanted hole that is inclined from the middle to the outside.

[0008] The PCBA board has round holes, an arc-shaped bottom, sloping sides on the top, and signal line holes in the middle.

[0009] The wire harness on one side of the plug is covered with heat shrink tubing, and the heat shrink tubing is wrapped with protective cloth. The other side of the heat shrink tubing is corrugated tubing.

[0010] The technical solution of this utility model has a novel structure and a clever and simple design. The ball socket and the lower ball socket assembly are engaged by the buckles b on both sides, which are firm and will not fall off. The PCBA board is clamped on the clamping post through the round hole. The clamping post has a raised strip to increase the friction and is secured by buckles a on both sides, which is safe and will not fall off. The PCBA board has a wire hole at the bottom, which facilitates the entry of wire harnesses and makes installation convenient. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0017] like Figure 1 , 2 As shown in Figures 3, 4, and 5, an electric strut ball-and-socket structure includes a plug 1 and a lower ball-and-socket assembly 5. The ball-and-socket 2 and the lower ball-and-socket assembly 5 are connected by a snap-fit. The ball-and-socket 2 is hollow in the middle and has a PCBA board 6 in the middle. The lower ball-and-socket assembly 5 has a wire-passing hole 8 in the middle. A wire harness passes through the wire-passing hole 8. The wire harness includes a power line a, a power line b, and a signal line. The power line a has a terminal, which is inserted into the ball-and-socket 2. The signal line and the power line b are soldered to the PCBA board 6. One end of the wire harness is connected to the PCBA board 6, and the other end of the wire harness is connected to the plug 1. A tube with a left sheath 4 is provided outside the front opening of the wire-passing hole 8. A glue plug 9 is provided between the tube opening and the wire harness. Glue is applied from the tube to the rear of the wire-passing hole 8. The signal line is a Hall effect wire.

[0018] The ball socket 2 is provided with a socket 14 and a terminal block 11 on both sides. The middle and bottom of the ball socket 2 are recessed inward.
