Description

Technical Field

[0001] The utility model relates to the technical field of insulating sheaths, in particular to an insulating sheath for a wire clamp of an equipment. Background Art

[0002] The SLG bolt-type copper-aluminum equipment clamp is designed for connecting busbar down conductors to the outlet terminals of various electrical equipment (such as transformers, circuit breakers, disconnectors, and wall bushings). Based on the material, outlet terminals are mainly divided into copper and aluminum.

[0003] To enhance cable clamp protection, an insulating sheath is often added. In humid or highly polluted environments, this sheath effectively prevents the cable clamp from being exposed, providing excellent insulation protection, thereby reducing maintenance costs, extending service life, and ensuring safety.

[0004] Figure 1 The existing insulating sheath structure of an equipment wire clamp is shown, which includes two horizontally raised fixing components. One is used to fix the bolt part of the wire clamp, and the other is used to fix the wide side part below the wire clamp. However, in actual application, this structure does not perfectly match the equipment wire clamp, especially the presence of excess space at the fixing component. This may cause the wire clamp to slip after being fixed, affecting the fixing effect. To improve this situation, the fixing component of the existing equipment wire clamp has been optimized to improve its matching degree with the insulating sheath. Therefore, the utility model introduces an insulating sheath for equipment wire clamp, which aims to effectively solve the above-mentioned problems. Utility Model Content

[0005] In response to the problems existing in the above-mentioned prior art, the utility model provides an insulating sheath for an equipment wire clamp, and optimizes the design of the equipment wire clamp at different positions along the incoming line direction to ensure that all parts of the wire clamp are well fixed and protected, thereby improving the matching degree and matching effect between the equipment wire clamp and the insulating sheath.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts an insulating sheath for a wire clamp of an equipment, comprising two protective shells, and the two protective shells are matched and docked with each other. The connection between the two protective shells is a connecting edge, and the connecting edge is provided with a plurality of small holes in sequence along the length direction. The locking member passes through the small holes to fix the two protective shells and form an accommodating space inside the two protective shells for fixing the equipment wire clamp;

[0007] The protective shell is sequentially connected with an incoming line portion, a first fixing portion, a connecting portion, a second fixing portion and an outgoing line portion along the incoming line direction, wherein:

[0008] The first fixing part is provided with a first raised section, a first connecting section, a second raised section, a second connecting section and a third raised section in sequence along the line direction. Both ends of the three raised sections are raised and form a bolt fixing space, while the middle part is concave and forms a concave space. The concave space is connected with the above-mentioned first connecting section and the second connecting section and has the same height to form a straight line space for the straight plate to pass through.

[0009] Preferably, the second fixing portion of the present invention has a first fixing segment, a straight segment and a second fixing segment, the straight segment is connected to the above-mentioned connecting portion and has the same height, and the first fixing segment and the second fixing segment are located on both sides of the straight segment respectively.

[0010] Preferably, in the present invention, the length of the first fixing section in a direction perpendicular to the incoming line is greater than that of the second fixing section.

[0011] Preferably, the top surfaces of the three raised sections all have openings, and the top cover is detachably designed on the top surface of the openings.

[0012] Preferably, both ends of the top cover are designed with fixing blocks, a buckle with a certain curvature is hingedly mounted on the fixing block, and both sides of the opening are provided with a clamping block that is a matching structure with the buckle.

[0014] Preferably, the clamping block is provided with a deep portion extending therefrom, and the fixing block is provided with a clamping groove for the deep portion to enter therein.

[0015] 1. This utility model features an insulated cable clamp with optimized design at different locations along the cable entry direction, ensuring secure fixation and comprehensive protection for all cable clamp locations. This significantly improves the compatibility and performance of the cable clamp and insulation jacket. Furthermore, this utility model incorporates detailed improvements to the bolt-fastening areas of the equipment.

[0016] Specifically, the first fixing section is cleverly designed as a multi-section structure, with three raised sections precisely corresponding to the three bolt fixing locations on the equipment wire clamp. Furthermore, these raised sections feature a two-high, one-low structure, ensuring the bolts are securely locked within the bolt fixing space, thus achieving a stable fixation of the wire clamp.

[0017] 2. This utility model introduces a structural innovation to the bolt fixing area and insulation plate design of the conventional equipment wire clamp insulation sheath. By cleverly introducing straight segments in the bolt fixing area and insulation plate, they ensure a close fit with the thick copper or aluminum connecting section of the equipment wire clamp. This also enhances the protection provided by the raised portion to the key parts of the equipment wire clamp, thereby achieving a more stable and secure insulation sheath fixation.

[0018] 3. Among the possible improvements, the present invention further optimizes the raised section to address the potential loosening of the clamp's bolted portion after long-term use. Specifically, the present invention designates the raised section as a detachable structure, facilitating regular inspection of the clamp's bolted portion within the raised section. This also greatly simplifies maintenance procedures, ensuring the long-term and safe use of the clamp. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to further understand the features and functions of the present invention, the structure of the present invention is described in detail below with reference to the accompanying drawings.

[0029] like Figure 2-5 As shown, the present invention provides a first embodiment of an insulating sheath for a device wire clamp. This embodiment focuses on detailed improvements to the specific structure of the device wire clamp. Specifically, the insulating sheath for a device wire clamp designed by the present invention comprises two mutually matching protective shells 1, which are fixed by a locking member 13 passing through a small hole 12 on a connecting edge 11. Preferably, in this embodiment, the locking member 13 can be a plastic nail. Of course, other structures that are threadedly matched with the small hole 12 can also be used to form an accommodating space for fixing the device wire clamp. The sheath is optimized to have multiple parts along the incoming line direction to ensure stable fixation and comprehensive protection of the wire clamp. Specifically, the protective shell 1 is sequentially connected with an incoming line part 2, a first fixed part 3, a connecting part 4, a second fixed part 5 and an outgoing line part 6 along the incoming line direction, thereby improving the matching degree and effect between the device wire clamp and the insulating sheath.

[0030] Among them, the first fixing part 3 adopts a multi-section design in particular, and the first fixing part 3 is provided with a first raised section 31, a first connecting section 32, a second raised section 33, a second connecting section 34 and a third raised section 35 in sequence along the incoming line direction. The three raised sections correspond to the three bolt fixing parts on the wire clamp, and both ends of the three raised sections are raised and form a bolt fixing space 7, while the middle part is concave and forms a concave space 8. The concave space 8 is connected with the above-mentioned first connecting section 32 and the second connecting section 34 and has the same height to form a straight space for the straight plate to pass through, and the two high and one low structure is used to ensure that the bolts are firmly fixed.

[0031] The second fixing part 5 includes a first fixing section 51, a straight section 52 and a second fixing section 53. The straight section 52 is connected to the connecting part 4 to provide a channel for the straight plate. Considering that the insulating plate part of the equipment wire clamp is usually wide on one side and narrow on the other side, in view of this, the length of the first fixing section 51 perpendicular to the incoming line direction is greater than that of the second fixing section 53 in the utility model.

[0032] Of course, the lengths of the first fixing section 51 and the second fixing section 53 perpendicular to the line feed direction may also be designed to be the same.

[0033] Furthermore, this embodiment introduces a straight line segment 52 structure into the bolt fixing portion and the insulating plate portion, thereby achieving a close fit with the wire clamp connection section and enhancing the protection of key portions.

[0034] In summary, the insulating sheath for the equipment wire clamp provided by the present invention forms a space for securing the equipment wire clamp by securing two matching protective shells 1 and locking members 13 (e.g., plastic nails). The sheath is designed with multiple sections along the incoming line direction to ensure stable fixation and comprehensive protection of the wire clamp. In particular, the first fixing section 3 adopts a multi-segment design, corresponding to the bolt fixing area on the wire clamp to achieve a secure bolt fixation; the second fixing section 5 is designed with a corresponding length, taking into account the shape characteristics of the insulating plate portion of the equipment wire clamp.

[0035] like Figure 6-8 As shown, the present invention provides a second embodiment of the insulating sheath of the equipment wire clamp. Based on the structure of the first embodiment, this embodiment further optimizes the structure of the insulating sheath of the equipment wire clamp and mainly addresses the problem that the bolt fixing part of the wire clamp may become loose after long-term use. The specific structural improvements are as follows:

[0036] The top surfaces of the three raised sections are designed as removable covers 9, facilitating inspection and maintenance of internal bolts and preventing loosening after prolonged use. Cover 9 is secured by the mating structure of clips 92 and blocks 72, while a fixed edge 73 is provided for the cover 9 to rest on. The recessed portion 721 on the block 72 and the slot 911 on the fixing block 91 further enhance the stability of cover 9.

[0037] Specifically, the top surfaces of the three raised sections all have openings 71, and the top cover 9 is detachably designed on the top surface of the opening 71. Fixed blocks 91 are designed at both ends of the top cover 9, and a buckle 92 with a certain curvature is hingedly installed on the fixed block 91. Blocks 72 that cooperate with the buckle 92 are provided on both sides of the opening 71. A fixed edge 73 for placing the top cover 9 is fixed on the opening 71, and a deep portion 721 extends from the block 72. A slot 911 for the deep portion 721 to enter is formed on the fixed block 91.

[0038] The steps for disassembling the top cover 9 are as follows:

[0039] Gently pull the buckles 92 on the fixing blocks 91 at both ends of the top cover 9 to loosen them from the blocks 72 on both sides of the opening 71. After the buckles 92 are loosened, observe the slots 911 on the fixing blocks 91 and the deep portions 721 on the blocks 72, and gently lift the top cover 9 to withdraw the deep portions 721 from the slots 911 to achieve further separation. When the buckles 92 and the blocks 72 are completely separated and the deep portions 721 withdraw from the slots 911, the top cover 9 can be removed from the top surface of the raised section and placed in a safe place for subsequent maintenance or inspection.

[0040] The steps for installing the top cover 9 are as follows:

[0041] After completing the inspection and repair of the interior of the bolt fixing space 7, prepare to reinstall the top cover 9, ensuring that the top surface of the top cover 9 and the raised section are clean and free of debris or dirt. Align the top cover 9 with the opening 71, ensuring that the fixed edge 73 on the top cover 9 is aligned with the edge of the opening 71. Gently place the top cover 9 on the opening 71, being careful not to use excessive force to avoid damage. Align the buckles 92 on the fixing blocks 91 at both ends of the top cover 9 with the blocks 72 on both sides of the opening 71, and gently press the top cover 9 so that the buckles 92 fit tightly with the blocks 72 to ensure the initial fixation of the top cover 9. Observe the slot 911 on the fixing block 91 and the deep portion 721 on the block 72 to ensure that the two are aligned. Press the top cover 9 further so that the deep portion 721 completely enters the slot 911 to achieve a secure locking of the top cover 9.

[0042] In summary, this embodiment further optimizes the raised section. In particular, the present invention designs the raised section as a detachable structure, which facilitates regular inspection of the bolted portion of the wire clamp inside the raised section and greatly simplifies the maintenance process, thereby ensuring the durability and safety of the wire clamp.

[0043] The present invention is not limited to the above-mentioned specific implementation methods. Various modifications made by ordinary technicians in this field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
