Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power, in particular to a power cable connection protection clamp. Background Art
[0002] During the construction process of laying power cables, for the core wire in the power cable and the protective sheath structure tightly wrapped on the outside, during construction, the tension applied to the core wire through the sheath is usually applied using a special power cable clamp.
[0003] However, during actual use, the conventional power cable clamp cannot protect the connection end of the power cable because the core wire and the sheath are not tightly combined, causing the connection end of the cable to be stressed and loose. For this reason, the present application discloses a power cable connection protection clamp, which removes stress from the connection end of the cable and prevents the connection end of the cable from being stressed and loosening. Utility Model Content
[0004] The utility model aims to solve the existing problems and provides a power cable connection protection clamp.
[0005] The utility model is realized by the following technical scheme: a power cable connection protection wire clamp, comprising a connecting piece and a clamp, the two ends of the connecting piece are symmetrically connected to the clamp, the connecting piece is arranged in an arc-shaped slat structure, and the two ends thereof are symmetrically connected to the clamp of the combined structure;
[0006] The chuck includes a threaded sleeve and a compression sleeve, the compression sleeve includes an end tube, one end of the end tube is connected to the end of a connecting plate of an arc-shaped slat structure, the other end of the end tube is integrally connected to the large end of a conical tube, a conical compression tube with a threaded sleeve is sleeved outside the conical tube, the large end of the conical compression tube is connected to one end of a nut of the threaded sleeve, and the nut is threadedly sleeved on the outside of the end tube.
[0007] As a further improvement to the above scheme, a plurality of ribs are connected along the axial direction on the outer curved surface of the connecting piece, and the plurality of ribs are evenly spaced on the cross section of the connecting piece to enhance the strength of the connecting piece and prevent the connecting piece from being deformed or even damaged by the multi-directional force generated by the non-linear displacement of the cable.
[0008] As a further improvement to the above solution, arc-shaped strips are arranged at intervals on the radially opposite sides of the connecting piece, and the outer side of the arc-shaped strip is connected to a full-length connecting support bar for covering and protecting the cable connection end to avoid interference from external forces.
[0009] As a further improvement to the above scheme, a notch is provided throughout the conical tube, which is used to deform the notch on the conical pressing tube through extrusion of the conical pressing tube. The conical pressing tube forms a plurality of conical arc plates through the notch, thereby contracting each other and squeezing the cable sleeved therein, fixing the cables at both ends, and preventing the cable connections from loosening.
[0010] As a further improvement to the above solution, the inner walls of the multiple conical arc plates formed by the notches of the conical pressure tube are provided with a rough surface to increase the friction force and ensure that the cable in the chuck cannot get loose.
[0011] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique idea, the cables are connected by the threaded sleeve and the compression sleeve in the chuck sleeve mounted on the two cable ends through the connecting piece, the sheath of the cable is squeezed by the external force, so that the sheath and the core wire in the cable are tightly connected as one, and the arc strip and the support strip on the connecting piece are used to protect the cable connection end from damage. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a first structural schematic diagram of the utility model.
[0013] Figure 2 This is a schematic diagram of the structure in which ribs and struts are arranged on the connecting plate. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 to Figure 2 As shown in, a power cable connection protection clamp comprises a connecting piece 1 and a clamp, wherein the two ends of the connecting piece 1 are symmetrically connected to the clamp, and the connecting piece 1 is arranged in an arc-shaped slat structure, and the two ends thereof are symmetrically connected to the clamp of the combined structure;
[0016] The chuck includes a threaded sleeve and a compression sleeve, the compression sleeve includes an end tube 2, one end of the end tube 2 is connected to the end of a connecting plate 1 of an arc-shaped slat structure, the other end of the end tube 2 is integrally connected to the large end of a conical tube 3, a conical compression tube 5 with a threaded sleeve is sleeved outside the conical tube 3, the large end of the conical compression tube 5 is connected to one end of a nut 6 of the threaded sleeve, and the nut 6 is threadedly sleeved on the outside of the end tube 2.
[0017] As a further improvement to the above scheme, a plurality of ribs 9 are connected along the axial direction on the outer curved surface of the connecting piece 1, and the plurality of ribs 9 are evenly spaced on the cross section of the connecting piece 1 to enhance the strength of the connecting piece 1 and prevent the connecting piece 1 from being deformed or even damaged by the multi-directional force generated by the non-linear displacement of the cable.
[0018] As a further improvement to the above solution, arc strips 7 are arranged at intervals on the radially opposite sides of the connecting piece 1, and a connecting support bar 8 is connected to the outer side of the arc strip 7 to cover and protect the cable connection end to avoid interference from external forces.
[0019] As a further improvement to the above scheme, a notch 4 is provided on the conical tube 3 through its entire length, which is used to deform the notch 4 on the conical pressing tube 5 through the extrusion of the conical pressing tube 5. The conical pressing tube 5 forms a plurality of conical arc plates through the notch 4, thereby contracting each other and squeezing the cables sleeved therein, fixing the cables at both ends, and preventing the cable connections from loosening.
[0020] As a further improvement to the above solution, the inner wall of the multiple conical arc plates formed by the notches 4 of the conical pressing tube 5 is provided with a rough surface to increase the friction force and ensure that the cable in the chuck cannot get loose.
[0021] The working principle of a power cable connection protection clamp is as follows: firstly, the ends of the two cables are respectively put through the compression sleeves (conical tube 3 and end tube 2), and then the ends of the two cables are led into the inner concave surface of the arc-shaped strip of the connecting piece 1, and then the ends of the two cables are connected, and the cables in the two clamps and the connecting piece 1 are in a loose, unstressed and unstraightened state, and finally, the component nut 6 in the clamp is screwed on the end tube 2, so that the nut 6 rotates and moves on the end tube 2, and at the same time, the conical pressure tube 5 integrally connected with the nut 6 rotates and moves outside the conical tube 3. The conical tube 3 is displaced, and the notches 4 on the conical tube 3 form a plurality of conical arc plates, that is, the inner wall of the conical pressing tube 5 squeezes the conical arc plates, so that the conical arc plates are displaced inwards to gather together, and then the inner curved surface of the conical arc plates squeezes the cables, and the patterns on the inner curved surface are pressed against the surface of the cables to increase the friction force, so that the cables and the conical tube 3 (chuck) are integrated, and finally the cables between the two chucks are always in a state of being unstressed and not straightened, so that the cable connection is protected by the above structure to prevent the cable connection ends from loosening.
[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
