[0024] Several improvements and modifications are made to the present invention in conjunction with the accompanying drawings, and these improvements and modifications should also be regarded as within the protection scope of the present invention. Example 1

[0025] like Figure 1-3 As shown, a new type of positioning wire clamp comprises a wire clamp body Ⅰ1, a wire clamp body Ⅱ2 and a pin rod 3, wherein a positioning key block 1-1 is provided on the inner side wall of the wire clamp body Ⅰ1, a positioning key slot 2-1 is provided on the wire clamp body Ⅱ2, and the positioning key block 1-1 is embedded and installed in the positioning key slot 2-1, and the positioning key block 1-1 is provided with a pin hole Ⅰ1-2 penetrating along the axial direction of the contact line, the wire clamp body Ⅱ2 is provided with a pin hole Ⅱ2-2 penetrating along the axial direction of the contact line, and the pin hole Ⅰ1-2 and the pin hole Ⅱ2-2 are correspondingly arranged, and the pin rod 3 is penetrated and installed in the pin hole Ⅰ1-2 and the pin hole Ⅱ2-2, so as to ensure the fixed connection between the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 in the horizontal plane direction (in this embodiment 1, the horizontal plane is parallel to the contact line);

[0026] The inner side surfaces of the bottom ends of the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 are both provided with a wire contact groove 4 - 1 , and the wire contact grooves 4 - 1 of the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 cooperate to form a wire accommodating cavity 4 for accommodating and installing the contact wire 5 .

[0027] In order to further ensure the connection stability of the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 in the vertical direction, a positioning pin 6 is also provided, and a semi-positioning pin hole Ⅰ1-3 is provided at the top of the wire clamp body Ⅰ1, and a semi-positioning pin hole Ⅱ2-3 is provided at the top of the wire clamp body Ⅱ2. The semi-positioning pin hole Ⅰ1-3 and the semi-positioning pin hole Ⅱ2-3 are fitted together to form a positioning pin hole 7 for installing the positioning pin 6.

[0028] In this embodiment 1, the specific positioning connection structure of the positioning pin 6 and the positioning pin hole 7 is as follows:

[0029] The circumferential wall surface of the positioning pin 6 is processed with a limiting groove 6-1, and the inner wall surfaces of the semi-positioning pin hole Ⅰ1-3 and the semi-positioning pin hole Ⅱ2-3 are processed with a limiting boss 7-1 along the circumferential direction, and the limiting boss 7-1 and the limiting groove 6-1 are matched and installed in a limiting manner. Figure 1 As shown, the limiting boss 7-1 is an annular boss, and the limiting groove 6-1 is an annular groove, and the two match each other.

[0030] In the present invention, the positioning connection structure between the positioning pin 6 and the positioning pin hole 7 can be but is not limited to the above structure, and any existing structure that can realize the connection between the positioning pin 6 and the positioning pin hole 7 can be applicable.

[0031] In order to further improve the installation stability of the contact line in the line receiving cavity 4, as Figure 1-2 As shown, the inner side surfaces of the bottom ends of the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 are each provided with a clamping block 8 for pulling and fastening the wire groove 5 - 1 on the contact wire 5 .

[0032] In this embodiment 1, the wire clamp body I1 and the wire clamp body II2 are integrally formed with the clamp block 8. Those skilled in the art can integrally form the clamp block 8 by designing the wire contact groove 4-1 when processing the wire contact groove 4-1, which is a conventional technical means.

At the same time, the positioning pin 6 needs to be placed in the positioning pin hole 7 first, and the part of the contact wire 5 is placed in the wire accommodating cavity 4 accordingly, so that the clamping block 8 of the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 can be buckled in the wire slot 5-1 of the contact wire 5. When the wire clamp body Ⅰ1 and the wire clamp body Ⅱ2 are fully installed and fitted, the positioning pin 6 and the contact wire 5 are simultaneously and respectively installed in the positioning pin hole 7 and the wire accommodating cavity 4. Finally, the pin rod 3 is inserted into the pin hole Ⅱ2-2 and the pin hole Ⅰ1-2 in sequence to complete the installation.
