Description

Technical Field

[0002] Cable crimpers are key tools in the power engineering industry used for splicing conductors during line foundation construction and maintenance. They are widely used in power line construction and maintenance operations, primarily for connecting cables or steel strands to terminals.

[0003] Currently, in high-altitude operations, such as the internal installation of wind turbines, it is necessary to perform power distribution connections on cables, which involves pre-connecting the cables to terminals. During this process, an appropriate length of the outer sheath must be stripped, typically 1.5 times the length of the terminal, ensuring that the terminal specifications match the conductor cross-sectional area. Then, the conductor is fully inserted into the terminal sleeve, and the sleeve is pressed using a die to form a cold weld connection with the conductor. Afterward, the uniformity of the crimped area must be visually inspected, and a light pull test must be performed to confirm the strength of the connection.

[0004] In practical applications, operators typically need to carry cable crimpers to the top of the wind turbine's casing for high-altitude work, i.e., using a wire crimping machine. However, the die slots on wire crimping machines are difficult to accommodate the crimping requirements of round or square terminals, which causes inconvenience for high-altitude operations.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Cable crimpers are key tools in the power engineering industry used for splicing conductors during line foundation construction and maintenance. They are widely used in power line construction and maintenance, primarily for connecting cables or steel strands to terminals. In high-altitude work scenarios, such as installation inside wind turbine generators, cable distribution connections are required, which involves pre-connecting the cables to terminals. During operation, an appropriate length of the outer sheath must be stripped, typically 1.5 times the terminal length, ensuring the terminal specifications match the conductor cross-sectional area. The conductor is then fully inserted into the terminal cylinder, and the cylinder is pressed using a die to form a cold weld connection with the conductor. Afterward, the crimped area is visually inspected for uniformity, and a light pull test is performed to confirm the connection's strength. In practical applications, operators often need to carry the cable crimper to the top of the wind turbine generator for high-altitude work, i.e., using a wire crimping machine. Example

[0021] Reference Figures 1-2This utility model provides a cable crimper for power engineering construction. Its basic components mainly include a body 100, a handle on the body 100, a removable battery 102 at the bottom of the body 100, a button 101, and a control panel electrically connected to the battery 102. A transmission structure 200, i.e., an electric telescopic cylinder, is also provided on the body 100. The electric telescopic cylinder is fixed inside the body 100, and its output end is connected to a pressing head 301, i.e., a pressing structure 300. The cylinder is powered by a storage battery 102 and controlled by a button 101 on the control panel. The operator only needs to select the corresponding pressing mode on the control panel, and the electric cylinder will drive the pressing head 301 to extend and retract on the clamp body 400, which is the main clamp plate 401. A reinforcing rib 402 is provided on the main clamp plate 401. The reinforcing rib 402 is integrally formed with the main clamp plate 401 and is made of stainless steel. In addition, a pressure sensor is also provided on the machine body 100 to monitor the pressure value in real time during the pressing process and feed the data back to the control panel.

[0022] Specifically, the operation of the electric telescopic cylinder can be started or stopped by button 101, which is simple and quick to operate. The removable battery 102 provides stable power support for the device. When the power is insufficient, it can be easily removed for charging or replacement, ensuring continuous use in high-altitude operations and other scenarios without interruption of work due to power problems. The handle is designed in accordance with ergonomic principles, providing a comfortable grip and reducing fatigue for operators even after long periods of use, facilitating precise operation during high-altitude work.

[0023] A pressing space is provided on the main clamp plate 401. One end of the pressing head 301 is set in the pressing space and is fixedly connected to the output end of the electric telescopic cylinder. The electric telescopic cylinder can drive the pressing head 301 to extend and retract within the pressing space. A slot 302 is provided on the pressing head 301, and two sets of limiting holes 303 are provided on the inner wall of the slot 302 for connecting the pressing block 600. Specifically, the clamp body 400 is provided with a slot 501 and a movable groove 502. A connecting block 601 is fixedly connected to the top of the pressure block 600. A limit plate 602 is provided on the top of the connecting block 601. The limit plate 602 is slidably connected in the movable groove 502, which is the connecting channel 500. A locking block 603 is fixedly connected to the side wall of the pressure block 600. An elastic ball 604 is provided on the locking block 603, and a spring is provided inside the locking block 603. The elastic ball 604 can elastically extend and retract under the action of the spring. The locking block 603 is compatible with the locking groove 302. When the pressure block 600 needs to be installed on the pressing head 301, the locking block 603 is aligned with the locking groove 302 and pushed in. The elastic ball 604 will be squeezed and contracted by the inner wall of the locking groove 302. When the locking block 603 moves to the position of the limiting hole 303, the elastic ball 604 pops out and locks into the limiting hole 303, thereby firmly connecting the pressure block 600 to the pressing head 301. When a crisp sound is heard when the elastic ball 604 locks into the limiting hole 303, it indicates that the pressure block 600 has been firmly installed in place and can be put into cable crimping work immediately.

[0024] This connection method is not only convenient for installation and disassembly, but also ensures that the pressure block 600 will not easily loosen or fall off during operation, ensuring the stable operation of cable crimping. At the same time, the slot 501 is used to adapt the connecting block 601 and the limiting plate 602. In actual operation, the construction personnel only need to align the connecting block 601 and the limiting plate 602 on the pressure block 600 with the slot 501 and gently push them in. The connecting block 601 and the limiting plate 602 can move back and forth in the movable groove 502. During the pushing process, since the movable groove 502 limits the movement trajectory of the connecting block 601 and the limiting plate 602, it can effectively prevent the pressure block 600 from shifting or shaking during installation.

[0025] Specifically, refer to Figure 3 and Figure 4 The pressure block 600 is provided with a slot 700. The slot 700 can be an arc-shaped slot 701 or a rectangular slot 702 on the pressure block 600 to meet the crimping requirements of different specifications of terminals, such as round terminals or square terminals. This brings convenience to high-altitude operations. Construction personnel only need to select the corresponding slot 700 according to the actual terminal shape for crimping operations. Moreover, the edge of the slot 700 is finely polished and the surface is smooth, which will not damage the cable terminal and ensure the quality of cable crimping. This allows high-altitude construction personnel to focus more on the cable crimping work itself.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
