[0002] In the field of power transmission and distribution, in order to achieve long-distance transmission of electric energy, terminals that can be plastically deformed are usually used to realize the electrical connection of two cables. Specifically, the two cables to be connected are respectively inserted into the two ends of the terminal, and then pressure is applied to the terminal to make it moderately deformed, so as to firmly connect the two cables.

[0003] The Chinese patent document with the authorization announcement number CN218498549U discloses a cable crimping device for electric power engineering construction. It drives the clamping block to move through the lower lead screw after rotation, adjusts the distance between the two clamping blocks, so that the terminal contacts both the cushion block and the clamping block, providing a pressing point for extruding the terminal. Subsequently, the upper lead screw is rotated to drive the connecting plate and the pressing head thereon to move downward, so that the upper and lower pressing heads jointly extrude the terminal, fixing the terminal at the end of the cable to complete the crimping.

[0004] However, in the prior art, when the terminal is long, it takes a lot of time to move the position of the terminal in the crimping device multiple times and repeat pressing it to complete the crimping work. Moreover, it is difficult to ensure that the terminal is uniformly pressed at each part during repeated pressing. Therefore, a cable crimping device for electric power construction is proposed.

[0027] The present utility model will be further described below through embodiments in conjunction with the drawings.

[0028] As Figures 1 - 5 shown, a cable crimping device for electric power construction includes a crimping component 2 that can fix the cable to be crimped and apply sufficient pressure to the terminal. Below the crimping component 2, there is a shifting component 1 that can adjust the horizontal position of the fixed cable and terminal in this device. Above the crimping component 2, there is a pressing component 3 that can adjust the pressure degree of the terminal according to the crimping requirement.

[0029] In this embodiment: The shifting component 1 includes a frame 101. Above the frame 101, a guide rail 102 is fixedly connected. On both sides of the frame 101, fixing seats 103 are fixedly installed. Between the fixing seats 103, a lead screw 104 is movably connected. One end of the lead screw 104 is fixedly connected to a motor 105. Between the guide rail 102 and the lead screw 104, a carrier 106 is provided.

[0030] Both the frame 101 and the guide rail 102 are slidably connected to the carrier 106. The fixing seat 103 is rotatably connected to the lead screw 104. The lead screw 104 is threadedly connected to the carrier 106.

[0031] The frame 101 provides an installation position for components such as the guide rail 102 and some components of the pressing component 3. The guide rail 102 restricts the movable range of the carrier 106. The motor 105 drives the lead screw 104 to rotate relative to the fixing seat 103. After rotation, the lead screw 104 drives the carrier 106 installed with the crimping component 2 to move horizontally above the frame 101.

[0032] In this embodiment: The crimping component 2 includes a clamping member for quickly fixing a cable, a pressing member for pressing the terminal at a fixed height, and a limiting member for restricting the movable range of the pressing member. The clamping member includes a base 201 fixedly installed on the shifting component 1. On both sides of the base 201, a buckle cover 202 is movably connected. On the buckle cover 202, a support rod 203 is movably connected. Between the support rods 203 with the same horizontal position, a pressing plate 204 is fixedly connected. On the outer side of the support rod 203, a spring 205 is movably connected. The limiting member includes a support 206 fixedly connected to one side of the buckle cover 202. Between the supports 206 with the same horizontal and vertical positions, a vertical rod 207 is fixedly connected. On the outer side of the vertical rod 207, a slider 208 is movably connected. Between the sliders 208 with the same vertical position, a cross bar 209 is fixedly connected. The pressing member includes a roller seat 210 movably connected to the outer side of the cross bar 209. Between the roller seats 210, a rotating roller 211 is movably connected. On the outer side of the rotating roller 211, a rolling block 212 is fixedly connected.

[0033] The base 201 is rotatably connected to the buckle cover 202. Both the buckle cover 202 and the spring 205 are slidably connected to the support rod 203. The vertical rod 207 is slidably connected to the slider 208. The cross bar 209 is slidably connected to the roller seat 210. The roller seat 210 is rotatably connected to the rotating roller 211.

[0034] Place the cable and terminals through the base 201. By rotating the cover 202 relative to the base 201, the cable and terminals are convenient to pick up and place. The pressing plate 204 installed in the cover 202 through the support rod 203 can press the contacted cable under the action of the spring 205. The vertical rod 207 installed on one side of the cover 202 through the support 206 can limit the movable range of the slider 208. The cross rod 209 connected to the slider 208 limits the movable range of the roller seat 210. The roller 211 is installed through the roller seat 210, so that the roller 211 can slide horizontally relative to the cross rod 209 along with the roller seat 210, and can rise and fall relative to the vertical rod 207 along with the roller seat 210, the cross rod 209, and the slider 208. The rolling block 212 contacts the terminal and presses the terminal when the height change of the roller 211 is limited.

[0035] In this embodiment: The pressing assembly 3 includes a hydraulic rod 301 fixedly installed above the frame 101. A lifting frame 302 is fixedly connected between the telescopic ends of the hydraulic rod 301. A support arm 303 is fixedly connected to the lower side of the lifting frame 302. A contact block 304 is fixedly connected to the lower end of the support arm 303.

[0036] The length change of the telescopic end of the hydraulic rod 301 is transmitted to the contact block 304 through the lifting frame 302 and the support arm 303. The two contact blocks 304 respectively contact the front and rear ends of the roller 211 to press the roller 211.

[0037] Working principle: When this device is installed and used for the cable crimping work related to power construction, after the cable and the terminal are initially connected, rotate the cover 202 upward relative to the base 201 to place the terminal in this device. After placing, reset the cover 202. During the reset process, the pressing plate 204 can contact the cable extending from one or both sides of the base 201 to the outside of this device. Under the action of the spring 205, the pressing plate 204 can press the cable to fix the cable.

[0038] After that, the horizontal position of the roller 211 can be adjusted, and the hydraulic rod 301 is made to work to drive the contact block 304 to descend, so that the two contact blocks 304 respectively buckle on the front and rear ends of the roller 211. Then, according to the crimping requirement, the hydraulic rod 301 makes the rolling block 212, which is supported by the terminal to a certain height at this time, press down by a certain height through the lifting frame 302, the support arm 303, the contact block 304, and the roller 211, so as to complete the crimping of the contact part between the terminal and the rolling block 212.

[0039] After the crimping of this part is completed, the motor 105 can be made to work to drive the carrier 106 to move horizontally. Since the horizontal movement of the roller 211 is restricted by the contact block 304, when the base 201 drives the cable and the terminal to move horizontally along with the carrier 106, each part of the terminal will fully withstand the downward pressure of the rolling block 212.

[0040] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the relevant technical field.
