Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary crimping equipment for motor cable heads, and specifically relates to a simple tool for cable shaping. Background Technology

[0002] In the field of power equipment maintenance, there are some problems in the on-site replacement of cable heads for motors. One problem is that the internal space of the junction box varies between different models of motors. The common narrow cavity has a volume range of only 0.5-2L, which severely compresses the operating space when performing cable terminal crimping.

[0003] The cross-sectional area of ​​power cables is typically 25-50 mm². 2 The rigidity of the cable makes it difficult to shape it precisely in a limited space. Maintenance personnel are forced to bend the cable to the terminal position by hand. The cable's springback means that the shape needs to be adjusted repeatedly during the crimping process. Moreover, when operating in a narrow junction box, maintenance personnel are prone to scratches and injuries to the back of their hands. Sharp edges of the cable armor layer and metal junction box openings can easily scratch operators, and the accident rate increases exponentially, especially in scenarios where multiple people are working together.

[0004] Current solutions rely on general-purpose tools such as adjustable wrenches or manual operation. Adjustable wrenches are too large to fit into junction boxes, while manual operation requires at least three people: one to hold the cable, one to crimp the terminals, and one to operate the crimping pliers, with each operation taking over 25 minutes. Currently, no cable shaping tool can simultaneously accommodate junction boxes of different sizes, resist rigid cable springback, and allow for safe single-person operation. Manual operation is not only inefficient but also poses a continuous safety threat. Therefore, a simplified cable shaping tool is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a simple cable shaping tool with auxiliary crimping function for cable heads in motor junction boxes, which solves the problems of inconsistent cable lengths, limited space in junction boxes, and difficulty in cable shaping and crimping without suitable tools in the existing technology.

[0006] To achieve the above objectives, the present invention provides a simple cable shaping tool, comprising a U-shaped clamp and an extension rod. The U-shaped clamp is composed of an arc-shaped bottom and symmetrical support arms on both sides. One end of the extension rod is vertically welded and fixed to the center position of the outer side of the support arm of the U-shaped clamp.

[0007] Preferably, the extension rod is a straight insulated steel pipe with a length of 250-350mm.

[0008] Preferably, the inner edge of the U-shaped clamp is polished to form a smooth transition.

[0009] Preferably, the inner side of the U-shaped clamp arm is provided with anti-slip texture.

[0010] Preferably, the opening of the U-shaped clamp arm is provided with a bolt positioning hole, an adjusting bolt passes through the bolt positioning hole, a silicone pressure pad is fixed to the inner end of the adjusting bolt, and a screwing part is provided at the outer end.

[0011] Preferably, the end of the extension rod away from the U-shaped clamp is provided with a handle, and the surface of the handle is covered with an insulating rubber layer.

[0012] Preferably, the entire surface of the U-shaped clamp is treated with insulating paint.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1 As shown, a simple cable shaping tool includes a U-shaped clamp 1 and an extension rod 2. The U-shaped clamp 1 consists of an arc-shaped bottom and symmetrical support arms on both sides. The arc-shaped bottom fits the cable, and the two support arms form a clamping cavity. One end of the extension rod 2 is vertically welded and fixed to the center of the outer side of the support arm of the U-shaped clamp 1. The extension rod 2 moves the operating position outside the junction box, avoiding the narrow space inside the box.

[0022] The specific design of the aforementioned key components will be discussed in detail below:

[0023] The extension rod 2 is a straight insulated steel pipe with a length of 250-350mm, preferably 300mm. The 300mm rod length extends beyond the depth of the junction box, allowing the operating end to protrude outside the box. With the arc-shaped bottom as the fulcrum, the operating lever arm is amplified.

[0024] The inner edge of the U-shaped clamp 1 is polished to create a smooth transition, with a transition arc radius R ≥ 2mm. The inner side of the support arm of the U-shaped clamp 1 is provided with anti-slip textures, which are 0.3-0.5mm deep serrations. These anti-slip textures engage with the cable surface, resisting rebound torque, and the smooth transition of the inner edge eliminates the risk of scratching the cable insulation layer.

[0025] The U-shaped clamp 1 has a bolt positioning hole at its opening. An adjusting bolt 3 passes through the bolt positioning hole, and a silicone pressure pad 4 is fixed to the inner end of the adjusting bolt 3. A screwing part 5 is provided at the outer end of the adjusting bolt 3. The silicone pressure pad 4 deforms under pressure to disperse the pressure and avoid indentation damage. The screwing part 5 adjusts the size of the opening of the U-shaped clamp 1 to accommodate cables of different thicknesses, and the silicone pressure pad 4 radially presses the cable.

[0026] The extension rod 2 has a handle 6 at the end furthest from the U-shaped clamp 1, and the surface of the handle 6 is covered with an insulating rubber layer. The insulating rubber layer is ≥2mm thick and has a diamond-shaped anti-slip texture, which reduces the gripping force required when operating with cotton gloves and prevents the tool from slipping out of the hand. The entire surface of the U-shaped clamp 1 is treated with insulating paint, which can withstand working voltage and protect personal safety.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
