Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to an anti-offline clamp and a connection method. Background Art

[0002] Cables in the power distribution line are connected by wire clamps. Commonly used wire clamps are divided into direct type and parallel type. Both types of wire clamps require the cable to be locked in the wire clamp by bolts. However, when the ambient temperature of the power distribution line changes, the space for placing the cable in the wire clamp will change due to thermal expansion and contraction. At this time, the bolt cannot be adjusted automatically, which may cause the connection between the wire clamp and the cable to be not tight enough, resulting in poor contact of the power distribution line, which not only affects the reliability of power supply, but also easily damages the equipment.

[0003] Therefore, it is urgent to provide an anti-dropping wire clamp and a connection method to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide an anti-offline clamp, which solves the problem that the connection between the existing clamp and the cable is not tight enough due to the change of the ambient temperature of the distribution line, and improves the tightness of the connection between the cable and the anti-offline clamp.

[0005] Another object of the present invention is to provide a connection method to improve the tightness of the connection between the cable and the anti-offset clamp.

[0011] As an optional solution of the above-mentioned anti-offline clamp, the limiting member is a trapezoidal structure, and the dimensions of the two ends of the limiting member in the first direction gradually decrease in directions away from each other.

[0012] As an optional solution of the above anti-offline clamp, the size of the first area in the first direction is equal to the diameter of the cable, and the size of the first area in the second direction is equal to twice the diameter of the cable.

[0013] As an optional solution of the above anti-offset clamp, the size of the second area in the first direction is equal to twice the diameter of the cable, and the size of the first area in the second direction is equal to twice the diameter of the cable.

[0014] As an optional solution of the above-mentioned anti-offline clamp, the size of the limiting member in the third direction is smaller than the size of the through hole in the third direction; the first direction, the second direction and the third direction are perpendicular to each other.

[0015] As an optional solution of the above-mentioned anti-offline clamp, the corners of the shell are all provided with arc chamfers.

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Existing wire clamps are divided into direct type and parallel type. Both types of wire clamps require the cable to be locked in the wire clamp by bolts. However, when the ambient temperature of the distribution line changes, the space for placing the cable in the wire clamp will change due to thermal expansion and contraction, which may make the connection between the wire clamp and the cable not tight enough.

[0041] Embodiment 1

[0042] Therefore, if Figure 1-Figure 3 As shown, this embodiment provides an anti-offline clamp. The anti-offline clamp is used to connect two cables 3. The anti-offline clamp includes a housing 1. A through hole is provided in the housing 1 to facilitate the insertion of the cables 3. The anti-offline clamp also includes a limit member 2, which is divided into a first limit member 21 and a second limit member 22. The first limit member 21 and the second limit member 22 are symmetrically arranged on the inner wall of the through hole relative to the axis of the through hole, and there is a gap between the first limit member 21 and the second limit member 22 to form a first area 11. The inner walls at both ends of the through hole and the side walls of the limit member 2 form a second area 12. From the arrangement of the above-mentioned limit member 2, it can be seen that the size of the first area 11 is smaller than that of the second area 12. The connecting end of one of the two cables 3 can be bent after passing through the first area 11 from one end of the through hole, and the connecting end of the other can be bent after passing through the first area 11 from the other end of the through hole; the bent connecting ends can be accommodated in the second area 12 and abut against the side wall of the limit member 2, thereby avoiding any bent connecting end from detaching from the anti-offline clamp after passing through the first area 11, thereby achieving a tight connection between the two cables 3.

[0043] Optionally, the stopper 2 is a trapezoidal structure, and the dimensions of the two ends of the stopper 2 in the first direction (i.e., the X direction in the figure) are gradually reduced in the direction away from each other. That is, the long bottom side of the stopper 2 is connected to the inner wall of the through hole, the short bottom side of the first stopper 21 and the short bottom side of the second stopper 22 are arranged oppositely, and the side wall of the first stopper 21 and the side wall of the second stopper 22 form a wedge-shaped structure, which increases the contact area between the stopper 2 and the cable 3, and further improves the stability of the connection between the cable 3 and the anti-offset clamp.

[0044] Further optionally, the size of the first area 11 in the first direction is equal to the diameter of the cable 3, and the size of the connecting end of the cable 3 in the first direction after bending is twice the diameter of the cable 3. Therefore, the size of the first area 11 in the first direction is set to ensure that the connecting end of the cable 3 before bending can pass through the first area 11, while avoiding the connecting end of the cable 3 after bending from passing through the first area 11, so that the cable 3 after bending cannot be separated from the anti-off clamp, so as to improve the stability of the connection between the cable 3 and the anti-off clamp while reducing the manufacturing cost and structural volume. Moreover, since the anti-off clamp connects two cables 3, the two cables 3 need to pass through the first area 11 at the same time. Therefore, the size of the first area 11 in the second direction (i.e., the Y direction in the figure) is equal to twice the diameter of the cable 3, so as to meet the basic requirements of the anti-off clamp connecting two cables 3 while compressing the size of the first area 11 in the first direction.

[0045] Further optionally, the size of the second area 12 in the first direction is equal to twice the diameter of the cable 3, so that the connection end of the cable 3 is arranged in the second area 12 after bending. The size of the first area 11 in the second direction is equal to twice the diameter of the cable 3, so that the second area 12 can accommodate two cables 3.

[0046] Further optionally, the size of the stopper 2 in the third direction (i.e., the Z direction in the figure) is smaller than the size of the through hole in the third direction, so as to leave sufficient space at both ends of the housing 1 to accommodate the connection end of the cable 3 after bending, and avoid the cable 3 being exposed due to the interference of the stopper 2. The first direction, the second direction and the third direction are perpendicular to each other.

[0047] Optionally, arc chamfers 13 are provided at the corners of the housing 1 to make the outer surface of the housing 1 smooth, which can avoid the occurrence of tip discharge to ensure the safety of the distribution line; on the other hand, it can prevent workers from being injured during the process of connecting the cable 3.

[0048] Optionally, the housing 1 and the stopper 2 are both metal parts, so that the anti-offline clamp has conductivity, so that the two connected cables 3 are electrically connected to ensure the conduction of the distribution line.

[0049] Further optionally, the housing 1 and the limiting member 2 are integrally formed, which reduces the difficulty of manufacturing the anti-offline clamp, thereby enabling the anti-offline clamp to be mass-produced and improving production efficiency.

[0050] Embodiment 2

[0051] like Figure 4 As shown, this embodiment provides a connection method, which uses the anti-offset clamp in the first embodiment to connect two cables 3.

[0052] Optionally, the connection method comprises the following steps:

[0053] S1, the housing 1 comprises a first end and a second end, wherein one cable 3 passes through the housing 1 from the first end, and another cable 3 passes through the housing 1 from the second end, and the two cables 3 are staggered along the second direction;

[0054] S2, the connecting end of the cable 3 is bent in the first direction after passing through the housing 1, and then the other end of the cable 3 is pulled so that the bent connecting end is arranged in the second area 12 and abuts against the side wall of the limiting member 2.

[0055] The above connection method only requires inserting the two cables 3 from the first end and the second end of the housing 1 respectively, then bending the connection ends of the two cables 3, and finally pulling the other end of the cable 3, so that the connection of the two cables 3 can be achieved through the anti-offline clamp. Compared with the traditional connection method, the connection efficiency is improved, and the tightness between the cable 3 and the anti-offline clamp is also improved.

[0056] Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
