Description

Technical Field

[0001] The invention relates to the field of low-voltage wire insulation, in particular to a reusable clamping insulation sleeve assembly device for low-voltage wires. Background Art

[0002] According to the provisions of my country's power safety work regulations, insulation wrapping is required when operating low-voltage live wires. In daily work, operation and maintenance personnel do not stop power when replacing electricity meters, air switches, and connecting household lines. During the replacement process, insulating tape is often used to wrap the exposed wires to prevent phase-to-phase short circuits and accidental touch by people, which may cause danger.

[0003] The current insulation wrapping method is to wear insulating gloves and wrap the exposed wire ends with insulating tape. The removed insulating tape can only be thrown away after wrapping, which is relatively wasteful. For wires with multiple strands of wires (such as neutral wire, live wire and ground wire) combined into one, the insulation wrapping requires that a single strand of the multiple strands of wire be led out separately and then wrapped with insulating tape. During the wrapping process, the operator may accidentally touch other strands of wire, which will cause safety problems if the wire is energized. Summary of the Invention

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0028] Example 1

[0029] Reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a reusable low-voltage wire clamping insulation sleeve assembly device, specifically including a wrapping and fixing mechanism 100, which includes a wrapping component 101 and a clamping component 102 arranged on the wrapping component 101; an adjusting mechanism 200, which includes an adjusting tube component 201 arranged at the lower part of the wrapping component 101, and a limiting component 202 fixed at the upper part of the adjusting tube component 201.

[0030] Furthermore, the wrapping assembly 101 includes a receiving head 101a, a receiving tube 101b fixed to the lower part of the receiving head 101a, and a guide member 101c fixed to the outer wall of the receiving tube 101b, and the clamping assembly 102 is slidably set on the guide member 101c.

[0031] Furthermore, the guide member 101c includes a first fixed rod 101c-1 fixed to the outer wall of the accommodating tube 101b and located above the annular groove P-3, a guide rod 101c-2 fixed to the end of the first fixed rod 101c-1, a second fixed rod 101c-3 fixed to the bottom of the guide rod 101c-2, and a guide ring 101c-4 fixed to the end of the second fixed rod 101c-3.

[0032] Preferably, the clamping assembly 102 includes an elastic ring 102a, and a limit frame 102b symmetrically fixed at both ends of the elastic ring 102a, and the limit frame 102b is slidably set on the outside of the guide rod 101c-2; the adjusting tube assembly 201 includes an adjusting tube 201a set below the accommodating tube 101b; the limit assembly 202 includes an extension block 202a symmetrically fixed on the upper part of the adjusting tube 201a, and a first limit block 202b and a second limit block 202c fixed on the side wall of the extension block 202a from top to bottom.

[0033] It should be noted that the width of the frame hole of the limit frame 102b is greater than the width of the guide rod 101c-2, which prevents the guide rod 101c-2 from squeezing the limit frame 102b when the elastic ring 102a changes from an elliptical shape to a circular shape; during the deformation of the elastic ring 102a, the edge of the limit frame 102b can always be between the first limit block 202b and the second limit block 202c.

[0034] In this embodiment, the operator cooperates with the tube adjustment component 201 and the limit component 202 to make the clamping component 102 clamped on the insulating sheath of the cable, so that the wrapping component 101 can wrap the end of the cable to prevent the conductive core from being exposed.

[0035] Example 2

[0036] Reference Figures 1 to 7 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0037] Specifically, a first accommodating cavity P-1 is provided in the accommodating head 101a, and a second accommodating cavity P-2 connected to the lower part of the first accommodating cavity P-1 is provided in the accommodating tube 101b; the wrapping assembly 101 also includes a partition 101d arranged in the first accommodating cavity P-1 and the second accommodating cavity P-2.

[0038] It should be noted that the first accommodating cavity P-1 is a spherical cavity, and the diameter of the first accommodating cavity P-1 is larger than the diameter of the second accommodating cavity P-2, which provides sufficient space for storing the exposed cores of the cable ends.

[0039] Furthermore, the partition 101d is composed of multiple groups of partition plates 101d-1 fixed at the same angle around the axis of the second accommodating chamber P-2; the partition plate 101d-1 includes a first partition portion 101d-2 arranged in the first accommodating chamber P-1, and a second partition portion 101d-3 fixed to the lower part of the first partition portion 101d-2, and the second partition portion 101d-3 is arranged in the second accommodating chamber P-2.

[0040] It should be noted that the number of groups of partition plates 101d-1 depends on the number of cores in the cable. Preferably, when there are four cores, there should also be four groups of partition plates 101d-1 to ensure that each core can be isolated.

[0041] Furthermore, an annular groove P-3 is provided on the bottom of the outer wall of the containing tube 101b, and an upper sliding pier 101e is fixed symmetrically with respect to the outer wall of the containing tube 101b in the annular groove P-3. The upper part of the upper sliding pier 101e is smoothly connected to the outer wall of the containing tube 101b, and the bottom of the upper sliding pier 101e is chamfered; the minimum inner diameter D-1 of the elastic ring 102a when not squeezed is smaller than the diameter of the containing tube 101b, and the maximum inner diameter D-2 is larger than the diameter of the containing tube 101b.

[0042] It should be noted that the elastic ring 102a is in an undeformed state when it is not squeezed. After the elastic ring 102a is on the accommodating tube 101b, the elastic ring 102a has been deformed, which enables the minimum inner diameter D-1 of the elastic ring 102a to be stuck on the upper sliding pier 101e, and the elastic ring 102a is fixed on the accommodating tube 101b through friction.

[0043] Preferably, a ring groove P-4 is provided on the outer wall of the adjustment tube 201a, and the guide ring 101c-4 is slidably set in the ring groove P-4; the extension block 202a is slidably set in the ring groove P-3, and the elastic ring 102a is slidably set between the first limit block 202b and the second limit block 202c.

[0044] In this embodiment, when the operator needs to install a reusable low-voltage wire clip-on insulating sleeve assembly device, he must first align each wire core with the second accommodating cavity P-2 separated by the partition plate 101d-1, and then hold the bottom of the adjusting tube 201a and insert it downward. During the downward insertion process, the wire core will first be inserted into the first accommodating cavity P-1, and then the wire core will press against the first accommodating cavity P-1, causing the adjusting tube 201a to slide downward relative to the wire core.

[0045] It should be noted that after the regulating tube 201a slides downward relative to the wire core, the top of the regulating tube 201a and the bottom of the receiving tube 101b are separated from each other, which allows the operator to observe whether the wire core is plugged in properly through the gap between the regulating tube 201a and the receiving tube 101b. If the operator sees the wire core not covered by the insulation sheath in the gap between the regulating tube 201a and the receiving tube 101b, it proves that it is not plugged in properly and needs to continue to press down from the top of the receiving head 101a, or directly remove the reusable low-voltage conductor. The wire is connected with an insulating sleeve assembly device, and then the exposed part of the wire core is shortened; if the operator sees the insulation skin in the gap between the adjusting tube 201a and the accommodating tube 101b, it proves that it has been inserted in place. Thereafter, the operator can continue to press down the adjusting tube 201a, so that the first limit block 202b drives the limit frame 102b to pull down the elastic ring 102a, and then the elastic ring 102a is clamped on the cable insulation skin. The elastic ring 102a clamped on the cable insulation skin can limit the position of the entire wrapping and fixing mechanism 100 relative to the cable.

[0046] It should also be noted that when the operator needs to disassemble the reusable low-voltage wire clamping insulation sleeve assembly device, he needs to hold the accommodating head 101a with one hand and hold the adjusting tube 201a with the other hand and rotate it. This will cause the limit assembly 202 to slide from the maximum inner diameter D-2 to the minimum inner diameter D-1, and the extension block 202a will expand the minimum inner diameter D-1, so that the elastic ring 102a is no longer pressed on the cable insulation skin. After that, the operator only needs to push the adjusting tube 201a upwards, so that the extension block 202a is slightly misaligned with the upper sliding pier 101e, so that the second limit block 202c pushes the elastic ring 102a back to the upper sliding pier 101e, and then rotate the adjusting tube 201a to make the limit assembly 202 align back to the limit frame 102b, thereby completing the resetting of the reusable low-voltage wire clamping insulation sleeve assembly device, and then directly unplug the reusable low-voltage wire clamping insulation sleeve assembly device from the cable.

[0047] It should be understood that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, the development effort will be a routine task of design, fabrication, and production without undue experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
