Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to an electrical engineering circuit connection device. Background Technology

[0002] Electrical engineering not only concerns the production, transmission, distribution, and use of electrical energy, but also involves many other aspects such as the manufacturing of electrical equipment. In practical applications, electrical engineering technologies and equipment are widely used in various scenarios. As a fundamental component of electrical engineering, the laying and connection methods of electrical wiring directly affect the stability and safety of the entire electrical system.

[0003] Traditional wire connection methods, such as wrapping the wire ends together, can achieve conductivity to some extent, but they have several drawbacks. First, this method is inefficient, requiring significant manual labor and time. Second, over prolonged use, the wrapped connection is prone to loosening or corrosion due to environmental and weather factors, affecting the wire's conductivity and potentially causing safety hazards.

[0004] To address the aforementioned issues, some quick-connection devices for electrical engineering circuits have emerged on the market, such as the Chinese patent with publication number CN112038819A, which describes a quick-connection device for electrical engineering circuits. This patented device improves the efficiency of wire connection and simplifies the operation process to some extent. However, in practical applications, these devices still have certain limitations. For example, when splicing cables, it is often impossible to effectively clamp and fix the cable ends. This means that after the cables are connected, external traction or vibration can easily cause the connection ends of the two wires to loosen. This loosening not only reduces the connection quality of the wire ends and affects the conductivity of the wires, but may also lead to instability in the electrical system and even cause safety accidents.

[0005] Therefore, in order to meet the urgent need in the field of electrical engineering for efficient, stable and safe wire connection methods, this utility model provides a new type of electrical engineering circuit connection device. Utility Model Content

[0006] To address the problem that existing wiring connection devices easily cause wires to detach, this utility model provides an electrical engineering wiring connection device. It aims to effectively clamp and fix the wires, ensuring the stability and reliability of the wire connection. This device will greatly improve the efficiency and quality of wire connections, providing strong support for the robust development of electrical engineering.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an electrical engineering circuit connection device, including a base, an insulating block on the top of the base, a transition conductor horizontally running through the interior of the insulating block, wiring grooves at both ends of the transition conductor, a pressure block above the wiring grooves on the transition conductor, the top of the pressure block being rotatably connected to an insulating threaded rod, and the insulating threaded rod being threadedly connected to the insulating block.

[0009] The top of the base is provided with sliding grooves on both sides of the insulating block. A bidirectional lead screw is horizontally installed through the insulating block and sliding groove below the adapter conductor. The bidirectional lead screw is connected through the fixed rings on both sides of the insulating block. The bottom of the fixed rings is slidably connected to the inside of the sliding groove. A ratchet unit and a support frame are fixedly installed at one end of the bidirectional lead screw. The support frame is located on the top of the base.

[0010] The fixing ring is symmetrically equipped with clamping screws, and the fixing ring is threaded through the clamping screws. One end of the clamping screw is connected to the clamping knob located on the outside of the fixing ring, and the other end of the clamping screw is rotatably connected to the clamping block located inside the fixing ring.

[0011] The ratchet unit includes a ratchet, which is mounted on a two-way lead screw. A movable groove is located on one side of the ratchet at the top of the base. One end of the ratchet is engaged with a pawl, and the pawl is slidably connected to the inside of the movable groove. The other end of the pawl is connected to a retaining spring located inside the movable groove.

[0012] The insulating block is equipped with a protective cover, the bottom of which is fixedly connected to the top of the base; a bidirectional screw is connected through the protective cover, and through holes coaxial with the wiring groove are provided on both sides of the protective cover; the insulating threaded rod is connected through the top of the protective cover.

[0013] A waterproof sealing ring is installed at the connection between the two-way lead screw and the protective cover.

[0014] A waterproof sleeve is installed at the through-hole of the protective cover, and one end of the waterproof sleeve is in close contact with the side of the adapter conductor.

[0015] The top of the insulated threaded rod is fixedly connected to the clamping knob, which is located above the protective cover.

[0016] The clamping block is made of the same material as the transition conductor.

[0017] The retaining ring is set on the same axis as the wiring groove.

[0018] A plug-in knob is fixedly installed at the other end of the bidirectional lead screw.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model discloses an electrical engineering wiring connection device that achieves efficient and stable wire connection by setting a fixing ring and a wiring slot. After the wire passes through the fixing ring, it is initially fixed. By rotating the bidirectional lead screw, the fixing ring drives the wire to move smoothly, ensuring that the wire is completely and accurately inserted into the wiring slot. Then, the clamping block firmly fixes the end of the wire in the wiring slot, realizing a reliable connection of the wire joint. The transition conductor can ensure the conduction of electrical energy. At the same time, the ratchet unit can effectively prevent the bidirectional lead screw from reversing, further enhancing the stability of the wire joint and avoiding loosening caused by pulling, thereby significantly improving the conductivity of the wire.

[0021] Furthermore, the fixing ring provided by this utility model is equipped with a clamping knob and a clamping screw, enabling quick and convenient fixing of the wire. After the wire passes through the fixing ring, rotating the clamping knob drives the clamping screw to rotate, causing the two clamping blocks inside the fixing ring to tightly clamp the wire, ensuring its stable position in the middle of the fixing ring.

[0022] Furthermore, the coaxial arrangement of the retaining ring and the wiring slot ensures the stability of the wire, making it easier to insert the wire into the wiring slot and effectively preventing the wire from shifting or shaking due to external forces, thus ensuring the stability and reliability of the wire connection.

[0023] Furthermore, the ratchet unit not only prevents the bidirectional screw from reversing, but also improves the flexibility of the device through the clamping spring, allowing the position of the retaining ring to be changed as needed.

[0024] Furthermore, protective covers are installed to protect the wiring points, ensuring the safe and stable operation of the electrical system in the event of extreme situations. Attached Figure Description
