The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The cable loading device 100 according to the embodiment of the present utility model is described below with reference to the drawings.

As shown in fig. 1, a cable loading device 100 according to an embodiment of the present utility model includes a frame 1 and a sliding assembly 2.

The sliding component 2 is connected with the frame body 1, and the sliding component 2 comprises a first limiting surface 20, wherein the first limiting surface 20 can move between a first position and a second position, and the first position and the second position are opposite in a first direction (for example, an up-down direction in fig. 1). In other words, when the first limiting surface 20 is at a certain position between the first position and the second position, the first limiting surface 20 can clamp the cable with the second limiting surface 10. It will be appreciated that the distance separating a certain defined position from the second stop surface 10 is related to the radial dimension of the cable.

The frame body 1 comprises a second limiting surface 10, the second limiting surface 10 is located between a first position and a second position in a first direction, and a cable is placed between the first limiting surface 20 and the second limiting surface 10, so that the first limiting surface 20 and the second limiting surface 10 limit the cable.

The cable loading device 100 according to the embodiment of the present utility model can move the first limiting surface 20 relative to the second limiting surface 10 in the first direction. The cable is placed between the first limiting surface 20 and the second limiting surface 10, and the first limiting surface 20 moves in the up-down direction, so that the cable is clamped by the first limiting surface 20 and the second limiting surface 10, the cable is manually clamped, and the operation safety is improved.

Therefore, the cable clamping device 100 provided by the embodiment of the utility model can replace manpower to clamp the cable, and the safety of clamping operation is improved.

In order to make the present utility model easier to understand, the cable loading device 100 according to the embodiment of the present utility model will be further described by taking the example that the first direction coincides with the up-down direction, the example that the second direction coincides with the left-right direction, and the example that the third direction coincides with the front-rear direction. The first direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction and the second direction.

In some embodiments, as shown in fig. 1, at least one of the first limiting surface 20 and the second limiting surface 10 is a curved surface, and the curved surface is adapted to the outer peripheral surface of the cable. In other words, the first limiting surface 20 is a curved surface; alternatively, the second limiting surface 10 is a curved surface; alternatively, the first limiting surface 20 and the second limiting surface 10 are curved surfaces.

When the first limiting surface 20 and the second limiting surface 10 clamp the cable, at least one of the first limiting surface 20 and the second limiting surface 10 is a curved surface, so that the cable can be constrained by the curved surface, and the cable part clamped on the first limiting surface 20 and the second limiting surface 10 is prevented from moving in the front-rear direction.

In some embodiments, as shown in fig. 1, the glide assembly 2 includes a slider 21, the slider 21 having a first limiting surface 20. The frame body 1 includes a holding portion 11, the holding portion 11 has a second stopper surface 10, the slider 21 and the holding portion 11 are opposed in the left-right direction, and the slider 21 is movable in the up-down direction so that the first stopper surface 20 moves in the up-down direction with respect to the second stopper surface 10.

In other words, the slider 21 and the clamping portion 11 are disposed opposite to each other in the left-right direction, and when the first limiting surface 20 and the second limiting surface 10 clamp the cable, a portion of the first limiting surface 20 adjacent to the second limiting surface 10 and a portion of the second limiting surface 10 adjacent to the first limiting surface 20 apply pressure to the cable, and the contact area with the cable is small. It will be appreciated that the cable is metallic and is subject to plastic deformation under compression, resulting in a change in its resistivity. The cable clamping device 100 of the embodiment of the utility model has smaller contact area with the cable when clamping the cable, so that the compression area of the cable is reduced, the plastic deformation area of the cable after compression is reduced, and the influence on the conductivity of the cable after clamping is avoided.

Specifically, the slider 21 includes a first through hole 211, a first stopper surface 20 is formed on an inner wall surface of the first through hole 211, the holding portion 11 is provided with a groove 111, a second stopper surface 10 is formed on an inner peripheral surface of the groove 111, the first through hole 211 is opposite to the groove 111 in the second direction, and one end of the groove 111 adjacent to the first through hole 211 in the second direction is opened.

In other words, the cable is sequentially passed through the first through hole 211 and the groove 111 at the time of use, and then the slider 21 is moved in the up-down direction so that the inner wall surface of the first through hole 211 and the inner peripheral surface of the groove 111. Thereby, not only the pressing area of the cable loading device 100 to the cable can be reduced, the influence of the electrical conductivity of the cable can be prevented, but also the restriction effect of the cable can be improved by using the restriction of the first through hole 211 and the groove 111.

In some embodiments, the axial direction of the wall surface inside the first through hole 211 coincides with the axial direction of the inner circumferential surface of the groove 111, and the right end of the first through hole 211 corresponds to the left end of the groove 111 (i.e., the open section of the groove 111) in the third direction.

Alternatively, the distance between the holding portion 11 and the slider 21 in the left-right direction is 0mm to 5mm. The distance between the holding portion 11 and the slider 21 in the left-right direction is 1mm to 4mm. The distance between the holding portion 11 and the slider 21 in the left-right direction is 2mm to 3mm. Thereby, the distance between the clamping part 11 and the sliding block 21 is ensured to be too large, so that the cable is bent when the clamping part 11 and the sliding block 21 clamp the cable, and the reduction of the clamping effect is avoided.

The distance of the holding portion 11 from the slider 21 in the left-right direction includes, but is not limited to, 0mm, 0.9mm, 1.2mm, 2mm, 2.5mm, 3mm, 3.4mm, 3.9mm, 4.3mm, or 5mm.

The radial dimension of the first through hole 211 and the groove 111 is 3mm-5mm, and the first through hole 211 and the groove 111 can be matched with a cable with the radial dimension of 3mm-5mm, so that the practicability of the cable clamping device 100 is improved.

The radial dimension of the first through hole 211 includes, but is not limited to, 3mm, 3.1mm, 3.5mm, 3.9mm, 4mm, 4.1mm, 4.5mm, or 5mm.
