Description

Technical Field

[0001] The utility model relates to the technical field of electricity, in particular to a connecting cable for electric power equipment. Background Art

[0002] Cables are commonly used wiring materials for interconnecting power between electrical equipment. When high-voltage lines want to connect to low-voltage lines, multi-stage transformers are often used for power transformation. The circuit connection between transformers mainly relies on cables.

[0003] However, due to the influence of different transformer installation and connection locations, cables often need to be bent at specific angles when connecting to meet wiring requirements. This bending not only increases stress concentration at the cable connection point, but also may affect the cable's insulation and electrical performance, and may even cause damage or failure during long-term use. Therefore, the utility model provides a connecting cable for power equipment to meet these requirements. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A connecting cable for electric power equipment comprises a cable body, both ends of which are provided with connecting terminals, and an insulating layer is provided on the outside of the cable body; a protective component, which is used to improve the strength of the cable body at the bend, and the protective component is connected to the cable body.

[0006] Optionally, the protective assembly includes two connecting parts that are in contact with the outside of the cable body, each of the two connecting parts is divided into two fixing parts and a connecting part, and fixing plates are provided on the opposite surfaces of the two connecting parts. The two fixing plates are fixedly connected by a bolt group, and gaskets are provided on the opposite surfaces of the two fixing plates.

[0007] Optionally, one end of the two connecting members and both ends of the connecting portion are provided with extension portions, the outer portions of the four extension portions are provided with two arc-shaped sleeves, and the interiors of the arc-shaped sleeves are provided with sliding grooves for the extension portions to slide.

[0008] Optionally, a second deformation cavity is provided inside the contact surface between the connecting portion and the cable body, and a first deformation cavity is provided inside the contact surfaces between the two connecting parts and the cable body.

[0009] Optionally, the connecting portion, the two fixing portions and the two arc-shaped sleeves form a ring structure, and the arc-shaped sleeves and the extending portion both have a certain degree of elasticity.

[0010] Optionally, the two connecting members are fixedly connected via two protective members, and the material of the protective members is hard rubber.

[0011] Optionally, the protective member is in an "H" shape, with both ends of the protective member respectively connected to the fixing portion and the connecting portion, a protrusion is provided on the side of the protective member facing the cable body, and a "C"-shaped inner cavity is provided inside the protrusion.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] In the above solution, the provision of a protective assembly, including a protective member made of a high-strength material such as hard rubber, significantly enhances the structural strength of the cable's bends. This reinforcement helps to resist the stress and tension generated during bending, preventing damage to the cable due to excessive bending. The protective member fits tightly against the cable body, reducing direct impact and wear on the cable's insulation layer from external factors. The shape and structure of the protective member help disperse stress when the cable bends, preventing stress concentration at a single point. This stress-dispersing effect helps extend the cable's service life and reduce failures caused by stress concentration.

[0014] In the above solution, the connector design allows it to fit snugly with cables of varying diameters. Whether the cable is thick or thin, the connector can be adjusted to ensure optimal fit and protection. The connector can deform appropriately when subjected to external forces, better adapting to the shape and size of the cable, thereby improving the adaptability of the protective component.

[0028] like Figure 1 As shown, an embodiment of the present invention provides a connecting cable for power equipment, including a cable body 1, both ends of the cable body 1 are provided with connecting terminals, and the outside of the cable body 1 is provided with an insulating layer; during the use of the power equipment, the connecting end of the power equipment and the connecting end of the transformer are connected through the terminals at both ends of the cable body 1, so that effective power transmission can be carried out between the power equipment and the transformer.

[0029] like Figures 1 to 4The protective assembly shown is used to improve the strength of the cable body 1 at the bend. The protective assembly is connected to the cable body 1. The protective assembly includes two connectors 2 that are in contact with the outside of the cable body 1. Each of the two connectors 2 is divided into two fixing portions 201 and a connecting portion 205. Fixed plates are provided on the opposite surfaces of the two connectors 2. The two fixing plates are fixedly connected by a bolt group 202. Gaskets are provided on the opposite surfaces of the two fixing plates. One end of the two connectors 2 and both ends of the connecting portion 205 are provided with an extension portion 207. The four extensions The outer sleeve of the portion 207 is provided with two arc sleeves 204, and the interior of the arc sleeve 204 is provided with a slide groove for the sliding of the extension portion 207. The interior of the contact surface between the connecting portion 205 and the cable body 1 is provided with a second deformation cavity 206, and the interior of the contact surface between the two connecting members 2 and the cable body 1 is provided with a first deformation cavity 203. The connecting portion 205, the two fixing portions 201 and the two arc sleeves 204 form a ring structure. The arc sleeve 204 and the extension portion 207 have a certain elasticity. When a part of the cable body 1 needs to be bent after connection, When the cable is bent, the protective component is installed at the cable section. During the installation process, the gap between the two fixing parts 201 is opened so that the cable body 1 can enter the interior of the connector 2 through the gap. When the two connectors 2 are both sleeved on the outside of the cable body 1, the fixing part 201 in each connector 2 is screwed through the bolt group 202, thereby completing the installation of the protective component. Among them, the design of the second deformation cavity 206 and the first deformation cavity 203 makes the connector 2 deformable when subjected to the pressure generated by the bending of the cable body 1. , and can undergo moderate deformation, thereby absorbing and dispersing stress. This deformation ability effectively reduces the damage to the cable body 1 during the bending process and improves the strength of its bending part. Through the deformation of the second deformation cavity 206 and the first deformation cavity 203, the connector 2 can better adapt to the bending shape of the cable body 1, ensuring the stability and reliability of the connection. This design makes the protective component less likely to loosen or be damaged during long-term use, thereby extending its service life, and the retractable extension part 207 can improve the adaptability rate of the protective component.

[0030] Among them, the two connecting parts 2 are fixedly connected by two protective parts 3. The material of the protective part 3 is hard rubber, and the shape of the protective part 3 is "H"-shaped. The two ends of the protective part 3 are respectively connected to the fixed part 201 and the connecting part 205. A protrusion 301 is provided on the side of the protective part 3 facing the cable body 1, and a "C"-shaped inner cavity 302 is opened inside the protrusion 301. The protective part 3 is made of "H"-shaped hard rubber material and has sufficient strength and elasticity. During the installation process, the two ends of the protective part 3 are respectively connected to the fixed part 201 and the connecting part 205 of the connecting part 2. When the cable body 1 is subjected to external force and needs to bend, the connecting part 2 and the second deformation cavity 206 and the first deformation cavity 203 inside it will deform to adapt to the bending shape of the cable body 1. The protective part 3, as a bridge between the connecting parts 2, will also undergo moderate deformation. Deformation, its "H"-shaped structure enables the protective part 3 to maintain good stability and support during the deformation process, the design of the raised part 301 and the "C"-shaped inner cavity 302 inside it enables the protective part 3 to absorb and disperse stress when deformed, thereby further reducing the damage to the cable body 1 during the bending process, and when the external force disappears, the connector 2 and the protective part 3 will return to their original shape and position. Since the protective part 3 is made of hard rubber material, it has good elastic recovery ability, so it can ensure stable performance during multiple bending and recovery processes, so that it can provide additional support and protection, and enhance the strength of the cable body 1 at the bend. The design of the raised part 301 and the "C"-shaped inner cavity 302 inside it enables the protective part 3 to absorb and disperse stress when deformed, thereby reducing the damage to the cable body 1 during the bending process.

[0031] The working principle provided by the present invention is that during the use of the power equipment, the connection end of the power equipment and the connection end of the transformer are connected through the terminals at both ends of the cable body 1, so that effective power transmission can be carried out between the power equipment and the transformer. When a part of the cable body 1 needs to be bent after the connection, a protective component is installed at the section of the cable. During the installation process, the gap between the opposite surfaces of the two fixing parts 201 is opened so that the cable body 1 can enter the interior of the connector 2 through the gap. When the two connectors 2 are both sleeved on the outside of the cable body 1, the fixing part 201 in each connector 2 is tightened through the bolt group 2. 02 is screwed together to complete the installation of the protective component. When the cable body 1 needs to be bent by external force, the connector 2 and the second deformation cavity 206 and the first deformation cavity 203 inside it will deform to adapt to the bending shape of the cable body 1. The protective member 3, as a bridge between the connectors 2, will also undergo moderate deformation. Its "H"-shaped structure enables the protective member 3 to maintain good stability and support during the deformation process. The design of the raised portion 301 and the "C"-shaped inner cavity 302 inside it enables the protective member 3 to absorb and disperse stress when deformed, thereby further reducing the damage to the cable body 1 during the bending process.
