Description

Technical Field

[0001] This utility model relates to the field of wire lug crimping technology, and in particular to a simple low-voltage cable wire lug crimping device. Background Technology

[0002] A secure connection between the lug and the cable plays a crucial role in the stability and reliability of power transmission. A weak connection increases contact resistance. When current flows through, this increased resistance causes a significant amount of electrical energy to be converted into heat, resulting in overheating. This overheating not only wastes energy and reduces power transmission efficiency, but in severe cases, it can also lead to fires and other safety accidents, posing a significant threat to personnel and property. Furthermore, an unstable connection can cause voltage fluctuations, affecting the normal operation of electrical equipment, such as causing malfunctions in precision electronic devices or abnormal motor operation, ultimately impacting the normal operation of the entire power system and causing considerable inconvenience to production and daily life.

[0003] Most current wire lug crimping devices use hydraulic methods for clamping, resulting in a large overall size and the need to carry a hydraulic power source, making them inconvenient to carry. They also have high operating costs for simple maintenance and small-scale crimping work. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0019] like Figures 1 to 3 As shown, a simple low-voltage cable nose crimping device includes a guide groove 1. Guide shafts 3 are fixedly connected to both sides of the inner wall of the guide groove 1. A sliding seat 4 is slidably connected to the outer walls of the two guide shafts 3 and the inner wall of the guide groove 1. A crimping connector 5 is fixedly connected to one end of the sliding seat 4 and the top of one end of the guide groove 1. A crimping interface 6 is opened in the middle of the side of the two crimping connectors 5 facing each other. The two crimping interfaces 6 correspond to each other. A support frame 2 is fixedly connected to the middle of the top surface of the guide groove 1. A connecting hinge 7 is fixedly connected to the center of the top surface of the support frame 2. A pressing handle 8 is rotatably connected to the top surface of the support frame 2 through the connecting hinge 7. A first connecting ear 9 is fixedly connected to the middle of the bottom of the pressing handle 8 near the support frame 2. A second connecting ear 11 is fixedly connected to the center of the top of the sliding seat 4. A connecting rod 10 is rotatably connected to the middle of the second connecting ear 11 and the first connecting ear 9. An operating handle 12 is fixedly connected to the end of the guide groove 1 away from the crimping connector 5.

[0020] As an optional technical solution of this utility model: the outer wall size of the pressure joint 5 at one end of the sliding seat 4 is adapted to the inner wall size of the support frame 2, and the pressure joint 5 is slidably connected to the support frame 2, thereby preventing the support frame 2 from interfering with the pressure joint 5.

[0021] As an optional technical solution of this utility model: a guide channel 14 is provided at the center of the top surface of the operating handle 12, and an adjusting screw 18 is rotatably connected to the center of the inner wall of the guide channel 14. A positioning block 15 is threadedly connected to the outer wall of the adjusting screw 18. One end of the adjusting screw 18 passes through the outside of the operating handle 12 and is fixedly connected to an adjusting nut 17. The positioning block 15 is slidably connected to the inner wall of the guide channel 14. By rotating the adjusting screw 18, the positioning block 15 can be driven to slide horizontally, thereby adjusting the blocking position of the sliding positioning plate 16. This allows for better control of the sliding distance of the sliding seat 4.

[0022] As an optional technical solution of this utility model: a connecting rod 13 is fixedly connected to the center of one side of the top surface of the sliding seat 4, and a sliding positioning plate 16 is fixedly connected to the end of the connecting rod 13 away from the sliding seat 4. The sliding positioning plate 16 is slidably connected to the guide channel 14. The sliding positioning plate 16 is located on the side of the positioning block 15 close to the adjusting nut 17. A through hole is opened in the middle of the sliding positioning plate 16. The through hole is sleeved on the outside of the adjusting screw 18. Through the top of the sliding positioning plate 16 and the positioning block 15, the sliding pressing distance of the sliding seat 4 can be limited, thereby realizing the control of the pressing force.

[0023] As an optional technical solution of this utility model: both crimping joints 5 are composed of several thin plates arranged in a staggered manner. The spacing between the thin plates of the two crimping joints 5 is adapted to the thickness of the thin plates. The crimping interface 6 is opened on one side of the thin plates. The staggered arrangement of the thin plates allows the two crimping joints 5 to interlock and tighten, reducing the clamping space of the crimping interface 6, which can tighten smaller wire lugs and improve adaptability.

[0024] The working process of this utility model is as follows: When the user uses it... 1) Place the wire lug onto the end of the cable, and then insert the crimping part into the crimping interface 6 of the two crimping connectors 5; 2) By rotating the adjusting screw 18, the positioning block 15 can be driven to slide horizontally, thereby adjusting the blocking position of the sliding positioning plate 16, which can control the sliding distance of the sliding seat 4 to be pressed according to actual needs. 3) By holding the operating handle 12 and pressing down the handle 8, the pressure is transmitted through the connecting rod 10, and the downward pressure is transmitted as a horizontal thrust to the sliding seat 4, so that one crimping joint 5 pushes towards the other crimping joint 5, thereby achieving left and right crimping by pressing the wire lugs together.

[0025] In summary, this utility model uses the crimping interfaces 6 on two crimping connectors 5 to press the wire lug and both sides of the wire end from left to right. By holding the operating handle 12 and pressing down on the handle 8, the pressure is transmitted through the connecting rod 10, and the downward pressure is transmitted as a horizontal thrust to the sliding seat 4, causing one crimping connector 5 to push towards the other crimping connector 5, thus achieving left and right crimping. The force-saving lever structure formed by pressing the handle 8 and the connecting rod 10 can amplify the pressure, achieving manual crimping without the need for hydraulic power equipment. Moreover, it has a rapid response, fast crimping speed, is easy to carry, and is suitable for maintenance and other ordinary operations. By rotating the adjusting screw 18, the positioning stop 15 can be driven to slide horizontally, thereby adjusting the blocking position of the sliding positioning plate 16. This allows for control of the sliding distance of the sliding seat 4 to press down according to actual needs, achieving pressure control of the wire lug.
