Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and in particular to a quick connector for power cables. Background Technology

[0002] In existing power equipment or power transmission, due to the limitation of transmission distance, it is sometimes necessary to connect two cables together for use. Most existing connection methods use twisting or hooking, which are relatively complicated and cumbersome to operate, resulting in low connection efficiency and affecting construction efficiency.

[0003] Existing quick-connect cable connectors require stripping the cable core before insertion into the connector. However, when the cable core is composed of multiple strands of fine copper wire, the wires are prone to splitting when directly inserted into the connector, affecting connection stability. Furthermore, existing connectors can only connect a limited number of cables, limiting their practical application. Therefore, we propose a quick-connect connector for power cables. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a quick connector for power cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick connector for power cables, comprising a housing, wherein the housing has multiple mating cavities, and mating plates distributed vertically are fixedly installed on the inner wall of the end of each mating cavity. Static contact plates distributed horizontally are fixedly installed in the middle section of the mating cavity. Both the mating plates and the static contact plates have mating grooves. A dynamic contact plate is movably installed inside the mating cavity, with both ends of the dynamic contact plate matching the mating grooves. A connecting plate is fixedly installed on the outer wall of the dynamic contact plate, and a clamping block is fixedly installed at the end of the connecting plate. The clamping block has a clamping groove inside. A plug rod is fixedly installed on the other outer wall of the dynamic contact plate, and a first protective sleeve is fixedly installed on the outer wall of the dynamic contact plate outside the plug rod. The first protective sleeve and the end of the plug rod extend through the housing to the outside of the housing.

[0006] Preferably, two symmetrically arranged first docking rods are fixedly installed inside the docking groove on the outer wall of the docking plate, and two symmetrically arranged second docking rods are fixedly installed inside the docking groove on the outer wall of the static contact plate. Furthermore, through holes that cooperate with the first and second docking rods are provided at both ends of the dynamic contact plate.

[0007] Preferably, the outer wall of the first protective sleeve has a groove, and a reinforcing pad is fixedly installed on the outer wall of the dynamic contact plate at the end of the insertion rod, and the reinforcing pad is located inside the first protective sleeve.

[0008] Preferably, the ends of the first and second connecting rods are all fixedly installed with fixing pads, which are frustum-shaped and elastically designed.

[0009] Preferably, a fixing ring is fixedly installed on the outer wall of the housing at the corresponding position of the docking cavity, and an installation ring is threaded onto the fixing ring. Multiple dustproof pads are fixedly installed inside the installation ring.

[0010] Preferably, a connecting rod is also fixedly installed on the outer wall of the dynamic contact plate, and the connecting rod is used in conjunction with the plug rod.

[0011] Preferably, a second protective sleeve is provided on the outer side of the connecting rod, the end of the second protective sleeve is fixedly connected to the outer wall of the dynamic contact plate, and a detachable end cap is movably installed on the end of the second protective sleeve, the end cap being threadedly connected to the end of the second protective sleeve. Beneficial effects

[0012] This invention provides a quick connector for power cables. It has the following advantages: (1) The quick connector for power cables connects the cable to the dynamic contact plate by clamping the inner core of the cable inside the clamping block. This ensures that the inner core of the cable, which is composed of multiple strands of fine copper wire, is fully connected to the dynamic contact plate. In addition, the dynamic contact plate slides along the guide rail to the mating groove of the static contact plate to complete the snap-fit. This allows multiple cables to be connected at once through the parallel static contact plates, avoiding multiple operations.

[0013] (2) The quick connector for power cables uses a plug-in connection between a plug rod and a connecting rod. When the number of cables exceeds the capacity of the housing, the plug rod of one housing is inserted into the connecting rod of another housing. A quick connection between a larger number of cables can be achieved through the connection between the two housings. Attached Figure Description

[0018] 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.

[0019] like Figure 1-6As shown, a quick connector for power cables includes a housing 1. The housing 1 has multiple mating cavities inside. The inner wall of the end of each mating cavity is fixedly installed with mating plates 7 distributed vertically. The middle section of the mating cavity is fixedly installed with static contact plates 15 distributed horizontally. Both the mating plates 7 and the static contact plates 15 have mating grooves 17. A dynamic contact plate 9 is movably installed inside the mating cavity. The two ends of the dynamic contact plate 9 are matched with the mating grooves 17. A connecting plate 10 is fixedly installed on the outer wall of the dynamic contact plate 9. A clamping block 11 is fixedly installed at the end of the connecting plate 10. The clamping block 11 has a clamping groove 12 inside. A plug rod 6 is fixedly installed on the other side of the outer wall of the dynamic contact plate 9. A first protective sleeve 5 is fixedly installed on the outer wall of the dynamic contact plate 9 outside the plug rod 6. The first protective sleeve 5 and the end of the plug rod 6 extend through the housing 1 to the outside of the housing 1. The number of docking cavities on each housing 1 is an even number. When the number of cables to be connected is no more than half the number of docking cavities on a single housing 1, the inner cores of the cables to be connected can be clamped and fixed in the clamping groove 12 in a symmetrical order, so that the cables are connected to the clamping block 11 and the connecting plate 10. Then, the user pulls the end of the first protective sleeve 5 to move the dynamic contact plate 9 connected with the cable to the middle of the docking cavity. The inside of the docking cavity is equipped with guide rails at both ends of the dynamic contact plate 9. The dynamic contact plate 9 can be accurately docked and installed on the static contact plate 15 by moving along the direction of the guide rails. The static contact plates 15 inside the multiple docking cavities are connected in a corresponding manner. That is, the dynamic contact plate 9 connected with the cable can be snapped onto the static contact plate 15 so that multiple cables can be quickly connected through the housing 1.

[0020] like Figure 1 and Figure 4 As shown, two symmetrically arranged first connecting rods 8 are fixedly installed inside the connecting groove 17 opened on the outer wall of the connecting plate 7, and two symmetrically arranged second connecting rods 13 are fixedly installed inside the connecting groove 17 opened on the outer wall of the static contact plate 15. The two ends of the dynamic contact plate 9 are provided with through holes that cooperate with the first connecting rods 8 and the second connecting rods 13. The inner diameter of the through holes at both ends of the dynamic contact plate 9 is larger than the outer diameter of the first connecting rods 8 and the second connecting rods 13. The arrangement of the first connecting rods 8 and the second connecting rods 13 can improve the connection strength between the dynamic contact plate 9 and the connecting plate 7 and the static contact plate 15, and can also improve the accuracy of the dynamic contact plate 9 when installing with the connecting groove 17 opened on the connecting plate 7 and the static contact plate 15.

[0021] like Figure 6As shown, the outer wall of the first protective sleeve 5 has a groove 16, and the outer wall of the dynamic contact plate 9 is fixedly installed with a reinforcing pad 18 on the outer side of the end of the insertion rod 6. The reinforcing pad 18 is located inside the first protective sleeve 5. The reinforcing pad 18 can strengthen the structural strength of the connection between the insertion rod 6 and the dynamic contact plate 9. The groove 16 on the outer wall of the first protective sleeve 5 makes it easy for the user to break the first protective sleeve 5 and expose the insertion rod 6.

[0022] like Figure 6 As shown, the ends of multiple first docking rods 8 and second docking rods 13 are all fixedly installed with fixing pads 14. The fixing pads 14 are frustoconical and elastically configured. The fixing pads 14 can deform when compressed. The fixing pads 14 can pass through the through holes opened at both ends of the dynamic contact plate 9 and move to the other side of the dynamic contact plate 9. The frustoconical structure of the fixing pads 14 can block both ends of the dynamic contact plate 9, thereby ensuring a stable connection between the dynamic contact plate 9 and the docking plate 7 and the static contact plate 15.

[0023] like Figure 5 As shown, a fixing ring 2 is fixedly installed on the outer wall of the housing 1 at the corresponding position of the docking cavity. An installation ring 3 is threadedly connected to the fixing ring 2. Multiple dustproof pads 4 are fixedly installed inside the installation ring 3. The installation ring 3 and the dustproof pads 4 can be removed from the fixing ring 2 and pre-fitted onto the outside of the cable. After the cable is connected to the dynamic contact plate 9, the installation ring 3 is threadedly connected to the fixing ring 2 to seal the open end of the docking cavity.

[0024] like Figure 5 As shown, the outer wall of the dynamic contact plate 9 can also be fixedly installed with a connecting rod 19, and the connecting rod 19 and the plug rod 6 are used in conjunction. When there are a large number of cables to be connected, the cables can be connected by the cooperation between the two specifications of the housing 1. The plug rod 6 is inserted into the inside of the connecting rod 19 to quickly connect the cables.

[0025] like Figure 5 As shown, a second protective sleeve 20 is provided on the outer side of the connecting rod 19. The end of the second protective sleeve 20 is fixedly connected to the outer wall of the dynamic contact plate 9, and a detachable end cap is movably installed on the end of the second protective sleeve 20. The end cap is threadedly connected to the end of the second protective sleeve 20. By rotating, the end cap can be separated from the second protective sleeve 20, exposing the end of the connecting rod 19, which facilitates the insertion of the insertion rod 6 into the interior of the connecting rod 19, so that the insertion rod 6 and the connecting rod 19 can be quickly connected.

[0026] The working principle of this utility model: In this technical solution, 9, 10, 11, 7, and 5 are all conductive materials. When the cable is clamped inside 11, and when 9 contacts 7 or 15, the circuit can be connected. In use, the usage method of this quick connector is selected according to the number of wires. The number of docking cavities opened on each housing 1 is always even. If the number of cables to be connected is not more than half the number of docking cavities on a single housing 1, the inner core of the cables to be connected can be clamped and fixed in the clamping groove 12 in a symmetrical order, so that the cables are connected to the clamping block 11 and the connecting plate 10. Then, the user pulls the end of the first protective sleeve 5 to move the dynamic contact plate 9 connected with the cable to the middle of the docking cavity. The inside of the docking cavity is located at both ends of the dynamic contact plate 9, and the dynamic contact plate 9 can be accurately docked and installed on the static contact plate 15 by moving along the direction of the guide rail. The static contact plates 15 inside the multiple docking cavities are connected in a corresponding manner, that is, the dynamic contact plate 9 connected with the cable can be snapped onto the static contact plate 15 to allow multiple cables to be quickly connected through the housing 1. If the number of docking cavities opened on a single housing 1 is even, the number of docking cavities on each housing 1 is even. If the number of docking cavities is insufficient for connecting cables, the user can use the connector with the connecting rod 19 on the dynamic contact plate 9 and the connector with the plug rod 6 on the dynamic contact plate 9. First, the user can clamp and fix the inner core of the cable on the clamping block 11 so that the cable is connected to the dynamic contact plate 9. Then, by pulling the ends of the first protective sleeve 5 and the second protective sleeve 20, the dynamic contact plate 9 is moved along the guide rail to contact the static contact plate 15. Next, by rotating the first protective sleeve 5, the dynamic contact plate 9 is rotated 90 degrees. Then, the first protective sleeve 5 is pulled outward so that the dynamic contact plate 9 inside the docking cavity is moved to be snapped onto the docking plate 7. Then, the user can break off the first protective sleeve 5 located outside the plug rod 6 to expose the plug rod 6. Then, the end cap at the end of the second protective sleeve 20 is removed so that the plug rod 6 can be inserted into the inside of the connecting rod 19, thereby enabling the cables connected on the two housings 1 to be quickly connected. After the plug rod 6 and the connecting rod 19 are inserted and connected, the user can wrap insulating tape around the outside of the two housings 1 to ensure the stability of the connection between the two housings 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
