Its main components include a ring part 31, a corrugated rod part 32 and a sleeve part 33 (as shown Figure 2 As shown, the end of the sleeve portion 33 away from the annular portion 31 has an eyelet), wherein the steel cable in the middle of the conductor 5 is inserted into the sleeve portion to press the sleeve portion partially to deform, so as to clamp the steel cable in the sleeve portion, and the aluminum sub-wire on the periphery of the conductor is wrapped outside the sleeve portion and the corrugated rod portion, and is wrapped and clamped by the wire sleeve 4 wrapped around the periphery, so that the aluminum sub-wire is wrapped and fastened outside the tension clamp 3 (as shown in FIG. Figure 3 As shown), the wire sleeve 4 has high requirements during installation, and the depth of its wrapping on the corrugated rod part must meet the requirements. Currently, X-ray equipment is mostly used for detection to determine whether it is qualified.

DETAILED DESCRIPTION

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0035] like Figure 4 and Figure 5 As shown, this embodiment provides a tension clamp back pressure comparison plate, including a plate body 11, and the shape and size of the plate body 11 are consistent with the axial cross-section of the tension clamp of the corresponding specification (that is, consistent with Figure 2 The outer contour and size of the cross-section at DD in the middle are consistent), so when the wire sleeve is pressed back on the tension clamp, the tension clamp can be aligning with the tension clamp using the tension clamp back-pressing comparison plate of the corresponding specification to compare the depth of the wire sleeve on the tension clamp, so as to judge whether the back-pressing process of the tension clamp is qualified.

[0036] The plate body 11 in the above technical solution is made of plastic material, which is light in weight and has low manufacturing cost.

[0037] The plate body 11 in the above technical solution is a transparent plate, so that it can be observed more conveniently during comparison.

[0038] The plate body 11 in the above technical solution has a thickness of 1-5 mm, which is moderate in thickness and is light to use.

[0039] The plate body 11 in the above technical solution includes an annular portion 111, a tooth plate portion 112 and a straight plate portion 113 which are connected in sequence. The middle portions of both sides of the tooth plate portion 112 are serrated to present a corrugated shape, and its structure is simple, so that the annular portion, the tooth plate portion and the straight plate portion correspond to the corresponding portions on the tension clamp respectively, for easy comparison.

[0040] In the above technical solution, the annular portion 111 is a waisted annular shape, and one end of the toothed plate portion 112 is connected to the long axis end of the annular portion 111, and one end of the straight plate portion 113 is connected to the other end of the toothed plate portion 112, and its structure is simple.

[0041] In the above technical solution, a length scale 12 is provided on one side of the plate body 11 corresponding to the toothed plate portion 112 and the straight plate portion 113, so that the depth of the wire sleeve can be understood according to the length scale (the zero scale line of the length scale 12 is located at the end of the straight plate portion away from the annular portion).

[0042] In the above technical solution, the width of the toothed plate portion 112 is greater than that of the straight plate portion 113 , and the connecting end of the toothed plate portion 112 and the straight plate portion 113 is gradually narrowed to form a bevel transition, thereby avoiding the appearance of overly sharp edges and corners.

[0043] The principle of the tension clamp back pressure comparison plate provided in this embodiment during comparison can be as follows: Figure 5As shown: the end of the annular portion of the tension clamp inverse pressure comparison plate away from the straight plate portion is aligned with the annular portion of the tension clamp (the alignment can be seen at the dotted line A). It can be seen that the depth of the wire sleeve 4 on the tension clamp is the vertical distance between the dotted line B and the dotted line C. Therefore, it is convenient to preliminarily judge the depth of the wire sleeve clamped on the tension clamp 3, and preliminarily judge whether the assembly of the wire sleeve is qualified. The comparison result of the tension clamp inverse pressure comparison plate can basically replace the detection of X-rays. Therefore, the comparison using the tension clamp inverse pressure comparison plate is efficient and accurate.

[0044] Of course, after the strain clamp 3, the conductor 5 and the wire sleeve are assembled, they can be compared with a strain clamp of the same specification. However, the strain clamp is heavier and more difficult to compare. Therefore, it is more convenient to use the strain clamp described in this embodiment to press the comparison plate for comparison.

[0045] Example 2

[0046] like Figure 6 As shown, the present embodiment provides a tension clamp backpressure comparison assembly, comprising a plurality of tension clamp backpressure comparison plates 1 as described above, each of the tension clamp backpressure comparison plates 1 having a different size, and corresponding to tension clamps of different specifications, respectively, a plurality of the plate bodies 11 are stacked in sequence along the order of size, and the ends thereof away from the straight plate portion 113 are aligned and rotatably connected, so that when encountering a comparison of tension clamps of different specifications, the tension clamp backpressure comparison plates of the corresponding specifications can be screwed out for use as needed, while the remaining tension clamp backpressure comparison plates are still in a stacked state.

[0047] like Figure 7 and Figure 8 As shown, the above technical solution also includes a rotating shaft 2, and a plate-shaped connecting ear 13 is provided at one end of the plate body 11 away from the straight plate portion 113, and an axial hole 131 is provided in the middle of the connecting ear 13. Multiple axial holes 131 are aligned and allow the rotating shaft 2 to pass through for rotational connection. It has a simple structure and is easy to use.

[0048] The connecting ear in the present embodiment is integrally formed with the annular portion, and the connecting ear on each tension clamp pressure comparison plate 1 has the same size, so that the connecting ear can be connected by rotation of the rotating shaft, and the annular portions of multiple tension clamp pressure comparison plates 1 and the connection points of the connecting ears are distributed in the same circle, so that when the multiple tension clamp pressure comparison plates 1 are swung to overlap each other, the ends of the multiple annular portions away from the straight plate portion are aligned with each other.

[0049] like Figure 8 As shown, the plurality of tension clamp back pressure comparison plates 1 can be swung to be unfolded to form a fan-shaped shape. Of course, only one tension clamp back pressure comparison plate 1 can be swung to be unfolded while the remaining tension clamp back pressure comparison plates 1 are still in an overlapping state.

[0050] In this embodiment, 3 to 5 tension clamp back pressure comparison plates 1 may be provided.

[0051] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
