Refer to Figure 3 , a connecting groove 122 is formed by the top end of the connecting housing 12 recessing inward. Both ends of the connecting groove 122 have openings and the top is also open. The fixator 11 is snapped into the connecting groove 122 from the top opening of the connecting groove 122, and the openings at both ends are used to avoid the fixator 11 or the rest of the electrode wire 30.

[0051] Refer to Figure 3-7 , positioning blocks 125 and abutting blocks 126 are provided on the side wall of the connecting groove 122. A positioning groove 114 is provided on the fixator 11. The abutting block 126 is provided at the end of the connecting groove 122, and the positioning block 125 is provided at the other end of the connecting groove 122. Refer to Figure 1 , when the fixator 11 is snap-connected to the connecting groove 122, one end of the fixator 11 abuts against the abutting block 126, and the positioning block 125 is cooperatively arranged in the positioning groove 114. The positioning block 125 and the abutting block 126 can assist in positioning the fixator 11 in the connecting groove 122, so that the conductive contacts on the electrode wire 30 can be aligned with the conductive elastic pieces 141 on the connecting housing 12, and at the same time, it can also prevent the fixator 11 from moving in the connecting groove 122.

[0052] Refer to Figures 5-7 , an electrode groove 112 and a spring piece groove 113 are provided on the fixator 11. Refer to Figure 7 , the electrode groove 112 has a first opening 1121 at the end and a second opening 1122 on the side.

The first opening 1121 and the fourth opening 1152 are respectively located at both ends of the fixator 11 to accommodate the other parts of the electrode wire 30. Refer to Figure 7 , the size of the second opening 1122 of the electrode groove 112 is smaller than the diameter of the electrode groove 112, so that the electrode wire 30 can be stably snapped in the electrode groove 112 and will not fall out.

[0053] Refer to Figure 6, the opening of the elastic piece groove 113 faces the bottom of the connection groove 122, and the elastic piece groove 113 is longitudinally communicated with the electrode groove 112, and then penetrates through the bottom of the connection groove 122, so that the electrical connection component 14 can pass through the elastic piece groove 113 and extend into the electrode groove 112 to be electrically connected with the conductive contact of the electrode wire 30. Refer to Figure 5 and Figure 6 , elastic piece grooves 113 are symmetrically arranged on both sides below the electrode groove 112. The bottoms and the opposite sides of the two mutually symmetric elastic piece grooves 113 are both provided with openings and are communicated with each other, effectively increasing the contact area between the electrical connection component 14 and the electrode wire 30 to improve the stability of the electrical connection. And, refer to Figure 5 , a partition 1131 is arranged between the bottoms of the two mutually symmetric elastic piece grooves 113. The partition 1131 can effectively improve the overall structural strength and stability of the holder 11, and prevent the holder 11 from breaking due to excessive hollowing area.

The top ends on both sides of the first connection portion 1411 extend out from two second through-holes 128 in each row. When the holder 11 is snap-fitted into the connection groove 122, the electrode wire 30 is electrically connected to the conductive elastic sheet 141, and the U-shaped first connection portion 1411 can apply a certain clamping force to the electrode wire 30, thereby improving the stability between the electrode wire 30 and the conductive elastic sheet 141.

[0057] Furthermore, the holder 11 and the connection housing 12 can also be locked and unlocked through the locking member 13 to further improve the stability of the connection between the electrode wire 30 and the conductive elastic sheet 141 and ensure the signal transmission efficiency.

[0058] It can be understood that the number of conductive elastic sheets 141 and the number of second through-holes 128 are respectively set corresponding to the number of conductive contacts of the electrode wire 30. For example, in this embodiment, the electrode wire 30 has an eight-contact structure, the number of conductive elastic sheets 141 is eight, and sixteen second through-holes 128 are provided and symmetrically arranged in two columns and eight rows.
