a bolt assembly 400 is disposed through the first kidney hole 140 and the second kidney hole 230 to secure the wedge assembly 200 to the clamp body 100.

In the prior art, there is a need to lead out sub-cables by clamping the main cable, which has a negative impact on the fixing of the wedge assembly due to the sub-cable addition. The existing structure is used for fixing the sub-cables, and if the loose condition occurs easily.

In the present utility model, one side of the wire clamp body 100 in the thickness direction is concavely formed with a mounting groove 110 penetrating the wire clamp body 100 in the length direction. The mounting groove 110 has a first through groove 120 and a second through groove 130 recessed inward at both ends in the width direction of the wire clip body 100, respectively. The mounting groove 110 provides mounting space for a subsequent wedge assembly 200. The clip body 100 is penetrated with a first kidney-shaped hole 140 provided along a width direction thereof.

The small through-posts 160 and large through-posts 150 provide for different sized sub-cable options or for simultaneous use.

The wedge assembly 200 is disposed within the mounting groove 110. The wedge block assembly 200 comprises a first wedge block 210 and a second wedge block 220 which are hinged with each other, a second kidney-shaped hole 230 is penetrated and arranged at the position of the wedge block assembly 200, corresponding to the first kidney-shaped hole 140, in the thickness direction, a small inner groove 211 and a large inner groove 212 which are respectively communicated with the small through column 160 and the large through column 150 are concavely arranged at the surface of the first wedge block 210, which faces the wire clamp main body 100. The presence of the small inner grooves 211 and the large inner grooves 212 protects the sub-cable, reducing the risk of damage thereof. One end of the first wedge 210 in the width direction is rotatably provided in the first through groove 120. One end of the second wedge 220, which is distant from the first wedge 210 in the width direction, corresponds to the second through groove 130, so that the second wedge 220 can clamp the main cable together with the clamp body 100. The arc-shaped elastic piece 300 the elastic piece 300 is arranged corresponding to the first through groove 120 and clamped by the first wedge block 210 and the first through groove 120. The elastic sheet 300 is provided with a small through hole and a large through hole corresponding to the small through column 160 and the large through column 150, so as to provide a foundation for penetration of the sub-cable. The radius of curvature of the cross section of the resilient tab 300 is greater than the radius of curvature of the cross section of the first channel 120, so that the resilient tab 300 provides a resilient force that provides a basis for the tightening of the wedge assembly 200. The elastic sheet 300 assists the bolt assembly 400 to provide a force for fastening the wedge assembly 200, thereby improving the overall fastening force and simultaneously serving as a redundancy safety. Specifically, the elastic sheet 300 is greatly increased in size compared to the spacer in the bolt assembly 400, and can provide a greater elastic force. The difference between the curvature radius of the elastic sheet 300 and the first through groove 120 can correspondingly adjust the fastening force provided, for example, in the case that the required fastening force is large, the thickness and the curvature radius of the elastic sheet 300 are increased.

The bolt assembly 400 is disposed through the first kidney hole 140 and the second kidney hole 230 to secure the wedge assembly 200 to the cleat body 100.

In summary, the presence of the small inner grooves 211 and the large inner grooves 212 on the first wedge 210 protects the sub-cable, reducing the risk of damage thereof; the arc-shaped elastic piece 300 is arranged corresponding to the first through groove 120 and clamped by the first wedge block 210 and the first through groove 120, and the curvature radius of the cross section of the elastic piece 300 is larger than that of the cross section of the first through groove 120, so that the elastic piece 300 provides elastic force, provides a foundation for fastening the wedge block assembly 200, and can serve as redundancy safety while improving the integral fastening force; the elastic sheet 300 is greatly increased in size compared to the spacer in the bolt assembly 400, and can provide a greater elastic force.

In one embodiment, the small inner groove 211 and the large inner groove 212 are arc grooves in the length direction.

In this embodiment, since the first wedge 210 is generally cast, the shapes of the small inner groove 211 and the large inner groove 212 in the length direction are not large for the lifting process of the forming complexity, so that the fixing friction force generated by the sub-cable in the small inner groove 211 and the large inner groove 212 in the length direction is raised in a manner of arc grooves, and the possibility that the sub-cable accidentally falls out of the first wedge 210 is reduced. Due to the improvement of the above-mentioned fixing effect, by the design of the elastic piece 300 and the arc design of the small inner groove 211 and the large inner groove 212, the wire clamp main body 100 does not need to be provided with screws corresponding to the small through column 160 and the large through column 150. In order to improve the fixing effect of the sub-cable in the prior art, after the sub-cable penetrates the small through-posts 160 and the large through-posts 150, the sub-cable is fixed by screwing the first screw and the second screw from the positions of the wire clamp main body 100 corresponding to the small through-posts 160 and the large through-posts 150 in the thickness direction.

In this embodiment, the fixing ring 420 in the bolt assembly 400 is structurally improved, one surface of the phase line clamp main body 100 of the fixing ring 420 is spherical, and a spherical groove 240 is arranged at a position corresponding to the fixing ring 420 on the outer surface of the corresponding wedge assembly 200, so that the fixing ring 420 and the wedge assembly 200 can form a joint structure. Specifically, the spherical recess 240 is located at either the first wedge 210 or the second wedge 220, depending on whether the first wedge 210 or the second wedge 220 is on the outer surface at the corresponding location.

In the process of installing the elastic piece 300, due to the arrangement of the small through holes and the large through holes, the elastic piece 300 may not exist in abnormal positions, but a shearing action may be generated between the elastic piece 300 and the wire clamp main body 100, and a certain damage may be performed on the sub-cable to a certain extent. In this embodiment, the small fixing cylinder extends into the small through-post 160, the large fixing cylinder extends into the large through-post 150, the damage to the cables between the elastic sheet 300 and the cable clamp main body 100 is blocked by the small fixing cylinder and the large fixing cylinder, and the deformation or rotation of a certain angle of the elastic sheet 300 can be ensured due to the clearance fit between the small fixing cylinder and the large fixing cylinder in the circumferential direction.
