Description

Technical Field

[0001] This utility model relates to the field of wiring technology, specifically to a quick connection device for electrical engineering circuits. Background Technology

[0002] Electrical equipment requires wiring to operate and to be powered. When wiring electrical circuits, multiple lines often need to be connected. Traditional electrical wiring connections primarily use bolt crimping and welding. For bolt crimping connections, operators must use wrenches and other tools to tighten each bolt individually. This is not only time-consuming and labor-intensive when there are many wires, but the tightening torque also depends on manual experience. Insufficient torque can lead to poor contact, increased resistance, and even localized overheating or burnout; excessive torque can damage the wire insulation or deform the terminals, creating safety hazards. Furthermore, bolts are prone to loosening in vibrating environments, requiring regular inspection and maintenance, further increasing operating costs. While welding connections can permanently fix the circuit, their application is strictly limited: on the one hand, the welding process requires specialized equipment and skills and cannot be operated in environments with little or no power supply; on the other hand, the quality of the welding points is greatly affected by the operator's skill level, and problems such as incomplete welding or missing welding can directly lead to circuit breaks. Moreover, the welded circuit is difficult to disassemble, and once a fault occurs, the original connection must be destroyed for repair, which greatly reduces the maintainability of the equipment.

[0003] Based on this, this application proposes a quick connection device for electrical engineering circuits. Utility Model Content

[0004] This utility model provides a quick connection device for electrical engineering circuits, which solves the problems mentioned in the background art, such as low connection efficiency and reliability that are easily affected by the operator's skill level when using bolt crimping and welding connection methods.

[0020] 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.

[0021] This utility model provides an embodiment: Please refer to Figures 1-5 A quick connection device for electrical engineering circuits includes a base 1. Both ends of the top of the base 1 are provided with cable troughs 9 adapted to electrical engineering circuit cables and positioning grooves 13 adapted to cable conductors. The positioning grooves 13 are U-shaped, and one end of the positioning grooves 13 is on the same straight line as the cable troughs 9. In use, the cable is located in the cable troughs 9. After the cable conductor is bent into a U-shape and placed into the positioning grooves 13, the positioning grooves 13 can limit the cable conductor, significantly reducing the risk of conductor displacement caused by external disturbances or vibration environment, and providing key structural protection for the tightness and long-term reliability of subsequent electrical connections.

[0022] The two positioning grooves 13 are connected by a lower conductor 10, which is embedded in the base 1. The end of the lower conductor 10 is connected to the groove wall of the positioning groove 13. With the lower conductor 10, the lower conductor 10 can serve as the current transmission medium for the two cable conductors, ensuring the continuity and stability of the current transmission path of the two cable conductors.

[0023] A rotating shaft 8 is movably connected to one end of the top of the base 1. The end of the rotating shaft 8 is fixedly connected to the pressure cover 2. Through the setting of the rotating shaft 8, the base 1 and the pressure cover 2 are in a movably connected state. There is damping between the rotating shaft 8 and the base 1. Under the action of external force, the pressure cover 2 can be opened and closed. When the external force is released, the position of the pressure cover 2 can remain unchanged. When the pressure cover 2 contacts the top of the base 1, the end of the pressure cover 2 away from the rotating shaft 8 is located on the outside of the base 1, forming a natural operating force space, which makes it easy for the user to open the pressure cover 2.

[0024] Both ends of the inner side of the pressure cover 2 are provided with a first limiting groove 11. The cable pressing block 5 is movably connected to the inner cavity of the first limiting groove 11. The cable pressing block 5 is connected to the top of the first limiting groove 11 through the first spring 7. The middle of the inner side of the pressure cover 2 is provided with a second limiting groove 12. The upper voltage guiding block 4 is movably connected to the second limiting groove 12. The upper voltage guiding block 4 is connected to the top of the second limiting groove 12 through the second spring 6. When the pressure cover 2 is in the closed state, the cable pressing block 5 is located above the end of the cable groove 9 near the positioning groove 13, and the upper voltage guiding block 4 is located above the two positioning grooves 13. In use, the rebound force of the first spring 7 can push the cable pressing block 5 to press the cable, thereby fixing the position of the cable. The rebound force of the second spring 6 can push the upper voltage guiding block 4 to press the cable conductor, thereby fixing the position of the cable conductor. This allows the two electrical engineering cables to be connected to be quickly connected, and the upper voltage guiding block 4 can be used as a current transmission medium between the two cable conductors.

[0025] As described above, this application allows for the simultaneous fixing of the cable body and cable conductors, and synchronous electrical conduction between two cables, significantly improving the connection efficiency and long-term operational reliability of electrical engineering cables. Furthermore, the adjustable clamping assembly formed by the first spring 7, the second spring 6, the cable clamping block 5, and the upper voltage-conducting block 4 can accommodate cables of various sizes, enhancing the device's adaptability.

[0026] In addition, a magnet plate 3 is provided at the top of the base 1. The cover 2, cable clamping block 5 and upper voltage conducting block 4 are all magnetically attracted to the magnet plate 3. Through the setting of the magnet plate 3, the magnetic attraction between the magnet plate 3 and the cover 2 effectively enhances the closing stability of the cover 2 and the base 1 when the cover 2 is closed, preventing unexpected opening due to vibration or external force. At the same time, the directional magnetic attraction between the magnet plate 3 and the cable clamping block 5 can strengthen the clamping effect of the cable clamping block 5 on the cable outer sheath and improve the mechanical fixation reliability of the cable body. Furthermore, the magnetic attraction between the magnet plate 3 and the upper voltage conducting block 4 further ensures that a tight electrical contact interface is formed between the upper voltage conducting block 4 and the cable conductor and the lower conductor 10. When the first spring 7 or the second spring 6 experiences elastic decay or failure due to prolonged use, the magnetic attraction between the magnet plate 3 and each functional component can sustainably maintain stable contact between the cable, cable conductor, upper voltage block 4, and lower conductor 10. This ensures that the device maintains reliable electrical conductivity and mechanical connection integrity even under extreme operating conditions, thereby significantly improving the safety margin and service life of the electrical engineering cable connection system. The materials of the magnet plate 3, pressure cap 2, cable pressure block 5, and upper voltage block 4 can be configured according to requirements and are not limited here.

[0027] In summary: During use, the user bends the exposed cable conductor into a U-shape. When placing the cable, the user opens the pressure cap 2 and inserts the cable conductor into the positioning groove 13. The end of the cable body closest to the cable conductor is located in the cable groove 9. Figure 3 As shown, after the two cables to be connected are placed, the pressure cap 2 is closed. When the pressure cap 2 is closed, the rebound force of the first spring 7 can accurately push the cable pressure block 5 to apply stable pressure to the cable outer sheath, thereby achieving mechanical fixation of the cable body. The rebound force of the second spring 6 synchronously drives the upper voltage block 4 to apply uniform contact pressure to the cable conductor, ensuring that the cable conductor, the lower conductor 10, and the upper voltage block 4 form a low-impedance electrical path. By closing the pressure cap 2, the cable body and the cable conductor are fixed at the same time, and electrical conduction is achieved between the two cables, which significantly improves the connection efficiency of electrical engineering cables.
