Technical Field
[0001] This utility model relates to the field of cable connector technology, specifically a portable power cable quick connector. Background Technology
[0002] Cables are typically made of one or more insulated conductors and an outer insulating protective layer, used to transmit electricity from one point to another. During cable laying, it is often necessary to connect and secure two cables to enable power transmission.
[0003] Utility model patent CN219268465U discloses a waterproof and sealed cable connector. This waterproof and sealed cable connector includes a cable connector body. Cable clamping claws are provided at both ends of the cable connector body. Tightening sleeves are installed around the cable clamping claws at both ends of the cable connector body. A sealing ring is installed at the center of the outer side of the tightening sleeve. Observation windows are installed at the center of the front and back of the cable connector body. A threaded tube opening is installed at the center of the top of the cable connector body. A sealing cap is installed around the threaded tube opening. A threaded hole is opened at the bottom of the threaded tube opening, penetrating the interior of the cable connector body. An adjusting screw is installed inside the threaded hole. The bottom end of the adjusting screw extends into the interior of the cable connector body and is provided with an upper cable connector pressure seat. A lower cable connector pressure seat is installed at the bottom of the inner wall of the cable connector body. Insulating pads are installed on the adjacent sides of both the upper and lower cable connector pressure seats. The cable connector features a tightening sleeve with a sealing ring, facilitating waterproof sealing at the cable insertion point. The cable joint is pulled to the top of the lower cable connector base, where it engages with the upper cable connector base via an internal inspection window. The adjusting screw inside the threaded tube lowers the upper cable connector base with its insulating pad, providing stable pressure and fixation to the cable joint end on the lower base's insulating pad. The cable clamping claws on the main body of the connector, in conjunction with the tightening sleeve, then tighten the sleeve, thus clamping and sealing the cable on both sides of the joint. This simple structure provides convenient waterproof sealing for cable joint protection, while also allowing for easy observation and adjustment to ensure insulation protection and prevent pull-induced breakage.
[0004] Although waterproof and sealed cable connectors facilitate cable connection, the device has the following problems during use: when connecting two cables, the device clamps and fixes the cables by using an upper and lower pressure seat, but this fixing method is not reliable. When the cables are subjected to external forces such as pulling, they are prone to falling off. In view of this, we propose a portable power cable quick connector. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0028] This embodiment provides a technical solution:
[0029] Please see Figures 1-5As shown, a portable power cable quick connector includes two symmetrical cables 1, each with a conductor 10 at its end. A conductive block 2 is positioned between the two conductors 10, with a fixing hole 20 on one end face of the conductive block 2 near the conductor 10. The conductor 10 passes through the fixing hole 20 and is fixed thereto. A fixing ring 21 is fixed to the outer wall of the conductive block 2, with fixing bolts 23 passing through its upper and lower sides. A connecting hole 24 is also provided at one end of the conductive block 2. A hollow mounting box 3 is installed between the two conductive blocks 2, with connecting pipes 30 installed at both ends of the mounting box 3. The openings of the connecting pipes 30 are provided with bolts on their upper and lower sides. The conductor 10 passes through the connecting tube 30 and is inserted into the mounting box 3 through the pit 301, and the fixing bolt 23 is threadedly connected to the threaded hole 301. A double-ended lead screw 32 is rotatably installed in the inner cavity of the mounting box 3. The double-ended lead screw 32 has threaded grooves 321 on both the upper and lower sides, and the threading directions of the threaded grooves 321 on the upper and lower sides are opposite. An insulating plate 36 is rotatably installed at each of the threaded grooves 321. A conductive plate 37 is fixed to each of the two opposite end faces of the two insulating plates 36. Two connectors 371 are fixed to each of the two opposite end faces of the two conductive plates 37, and the connectors 371 on the upper and lower sides are inserted into the corresponding connecting holes 24.
[0030] In this embodiment, a sealing ring 22 is coaxially fixed to one end face of the fixing ring 21 near the connecting pipe 30. A sealing groove 302 is provided on one end face of the connecting pipe 30, and the sealing ring 22 is inserted into the sealing groove 302. This design achieves a good sealing effect. It not only enhances the stability of the connection but also effectively prevents fluid or gas leakage at the connection point, improving overall safety and reliability.
[0031] In this embodiment, a sealing seat 34 is installed on the top of the mounting box 3, and the top end of the double-ended lead screw 32 passes through the sealing seat 34 and is coaxially fixed with a screw head 33. This design allows users to adjust or tighten the connection by turning the screw head, improving the ease of operation. At the same time, the sealing seat also provides a certain degree of dust and water protection.
[0032] In this embodiment, a removable sealing cover 35 is provided on the outside of the sealing seat 34, and the sealing cover 35 is threadedly connected to the sealing seat 34. The threaded connection design makes the installation and removal of the sealing cover 35 easier, and also improves the sealing performance at the sealing seat 34.
[0033] In this embodiment, the sealing seat 34 has an open bottom, and the outer wall of the sealing seat 34 is provided with multiple anti-slip ridges. The anti-slip ridge design not only improves the user's grip comfort but also increases the stability of operation, preventing slippage during adjustment or tightening.
[0034] In this embodiment, guide rods 31 are fixed near the four corners of the mounting box 3. The guide rods 31 pass through the insulating plate 36 and are slidably connected to the insulating plate 36. This design ensures the stability and guidance of the insulating plate 36 during movement.
[0035] In this embodiment, the conductive plate 37 and the connector 371 are integrally formed structures, and both the conductive plate 37 and the connector 371 are made of galvanized steel. This design increases the overall strength and durability of the conductive plate 37 and the connector 371, while the galvanized steel improves its corrosion resistance and conductivity, ensuring the stability and safety of power transmission.
[0036] It should be added that, in this embodiment, the conductive block 2 is made of a metal conductive material, and the fixing ring 21 is made of a ceramic material. The fixing ring 21 is tightly bonded to the conductive block 2, and the conductive block 2 and the conductor 10 are fixed by pressing. This design facilitates a stable connection between the conductor 10 and the conductive block 2. After the conductive block 2 is installed in the mounting box 3, insulation measures need to be applied to the exposed outer wall of the conductive block 2, such as wrapping it with insulating tape, so as to avoid the conductive block 2 being exposed and causing safety accidents, and to ensure the safety of the device.
[0037] In practical use, the user first passes one end of the conductive block 2 through the connecting pipe 30 and inserts it into the mounting box 3. Then, the user passes the fixing bolt 23 through the fixing ring 21 and tightens it with the threaded hole 301. The conductive block 2 is then fixed to the connecting pipe 30. Repeat the above steps and install the conductive block 2 on the other side. Then, the user rotates the screw head 33. The rotation of the screw head 33 drives the double-ended screw 32 to rotate. At this time, the upper and lower insulating plates 36 move towards the center synchronously and drive the conductive plate 37 to move. At the same time, the connector 371 is inserted into the connecting hole 24. When the upper and lower conductive plates 37 clamp the conductive block 2, stop rotating the screw head 33. Finally, the user tightens the sealing cover 35 onto the sealing seat 34.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
