Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of splicing fittings technology, and more specifically, to an improved splicing fitting for power transmission and distribution. Background Technology

[0002] Splicing fittings are fittings used to connect two conductors and meet the mechanical and electrical performance requirements of the conductors. They are divided into two types: load-bearing splicing fittings and non-load-bearing splicing fittings. Overhead transmission lines require splicing fittings for connection. For conductors, splicing fittings must not only connect the current path but also bear the tension of the conductor. Their strength and holding power must be no less than 95% of the conductor's calculated breaking strength.

[0003] Currently, the splicing hardware used for power cable connections on the market requires assembly and connection of the splicing hardware when connecting power cables. After assembly and connection, it is not convenient to pass the cable through and tighten the cable, resulting in a lot of assembly time being spent on cable connection.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an improved power transmission and distribution splicing fitting, which solves the technical problem in the prior art that when connecting power cables, it is necessary to assemble and connect the splicing fitting, and after assembly and docking, it is not convenient to pass the cable through and tighten the cable, thus resulting in a lot of assembly time when connecting the cable.

[0011] As a further technical solution, a drive screw is rotatably connected inside the groove, and a pressure block is slidably connected to the inner rod. The pressure block and the drive screw are connected by a threaded engagement.

[0012] As a further technical solution, the side end face of the clamping block is provided with a notch, the opening size of the notch is larger than the diameter of the inner rod, the side end face of the pressure block slides against the side end face of the clamping block, and a pair of clamping layers are provided on the side end face of the clamping block.

[0013] As a further technical solution, the docking and fixing assembly includes several threaded grooves, all of which are formed on the bottom surface of the main frame. The sub-frame is attached to the bottom surface of the main frame, and several bolts are inserted in the sub-frame. The upper ends of the bolts are screwed into the threaded grooves.

[0014] As a further technical solution, the surface curvature of the clamping block located in the clamping layer is the same as the surface curvature of the main groove.

[0015] As a further technical solution, both surfaces of the pressure block and the clamping block that slide in contact are arc-shaped transition structures.

[0034] like Figures 1-4 As shown, it illustrates an improved power transmission and distribution connection fitting according to an embodiment of the present disclosure, comprising:

[0035] Main frame 1 and sub-frame 2, with sub-frame 2 located at the bottom of main frame 1;

[0036] A pair of main slots 3 and a clamping assembly 5, the main slots 3 are opened at both ends of the surface of the main frame 1, and the clamping assembly 5 is disposed in the main slots 3 and the main frame 1;

[0037] The secondary slot 4 and the docking and fixing component 6 are provided. The secondary slot 4 is opened in the middle, and the docking and fixing component 6 is arranged between the main frame 1 and the secondary frame 2.

[0038] The clamping assembly 5 includes a pair of grooves 5-1, which are formed at both ends of the surface of the main frame 1. An inner rod 5-2 is provided in the groove 5-1. A through-hole 5-3 is formed on the inner surface of the main groove 3, which is connected to the groove 5-1. A clamping block 5-4 is slidably embedded in the through-hole 5-3. A drive screw 5-5 is rotatably connected in the groove 5-1. A pressure block 5-6 is slidably connected on the inner rod 5-2. The pressure block 5-6 is connected to the drive screw 5-5 by a threaded engagement. A notch 5-7 is formed on the side end face of the clamping block 5-4. The opening size of the notch 5-7 is larger than the diameter of the inner rod 5-2. The side end face of the pressure block 5-6 is slidably attached to the side end face of the clamping block 5-4. A pair of clamping layers 5-8 are provided on the side end face of the clamping block 5-4.

[0039] In some examples, to achieve a firm cable clamping effect, a clamping component 5 is designed, including a pair of grooves 5-1. The pair of grooves 5-1 are opened at both ends of the surface of the main frame 1. An inner rod 5-2 is provided in the groove 5-1. A through-hole 5-3 is opened on the inner surface of the main groove 3 and communicates with the groove 5-1. A clamping block 5-4 is slidably embedded in the through-hole 5-3. A drive screw 5-5 is rotatably connected in the groove 5-1. A pressure block 5-6 is slidably connected to the inner rod 5-2 and is threadedly connected to the drive screw 5-5. The side end face of the pressure block 5-6 is slidably attached to the side end face of the clamping block 5-4. The drive screw 5-5 can be turned to control the movement of the pressure block 5-6. When moving, it can push the clamping block 5-4. A pair of clamping layers 5-8 are also provided on the side end face of the clamping block 5-4. The clamping block 5-4 and the clamping layers 5-8 can clamp the cable in the main groove 3.

[0040] like Figures 1-4 As shown, this embodiment proposes a docking and fixing component 6, which includes several threaded grooves 6-1. The threaded grooves 6-1 are all opened on the bottom surface of the main frame 1. The sub-frame 2 is attached to the bottom surface of the main frame 1. Several bolts 6-2 are inserted in the sub-frame 2. The upper end of the bolts 6-2 is screwed into the threaded groove 6-1.

[0041] In some examples, in order to achieve the effect of fixed connection between the sub-frame 2 and the main frame 1, a docking fixing component 6 is designed. Multiple threaded grooves 6-1 are opened on the bottom surface of the main frame 1. Bolts 6-2 corresponding to the positions of the threaded grooves 6-1 are inserted into the sub-frame 2 and can be screwed into the threaded grooves 6-1 to fix the sub-frame 2 and the main frame 1.

[0042] For example, such as Figure 3 As shown, the surface curvature of the clamping block 5-4 located in the clamping layer 5-8 is the same as the surface curvature of the main groove 3.

[0043] In some examples, the curved surface structure allows the clamping block 5-4 to fit the shape of the main groove 3 and wrap around the cable.

[0044] For example, such as Figure 1 As shown, the two surfaces of the pressure block 5-6 and the clamping block 5-4 that slide together are both arc-shaped transition surfaces.

[0045] In some examples, the curved transition surface reduces the surface friction between pressure block 5-6 and clamping block 5-4, making installation easier.

[0046] For example, such as Figure 1 As shown, the main frame 1 has outer grooves 7 on both ends, and one end of the drive screw 5-5 is located in the outer groove 7. One end of the screw has a hexagonal concave structure.

[0047] In some examples, by providing an outer groove 7, the rotatable end of the drive screw 5-5 is placed in the outer groove 7 to prevent it from protruding outwards and affecting installation.

[0048] For example, such as Figure 1 As shown, hooks 8 are fixedly connected to both ends of the surface of the main frame 1.

[0049] In some examples, hooks 8 are provided to facilitate hanging up for installation and use.

[0050] For example, such as Figure 4 As shown, the end face of the clamping layer 5-8 has a toothed structure.

[0051] In some examples, the toothed structural surface can be inserted into the inside of the cable to enhance the fixing effect.

[0052] In actual use, place the power cable in the main slot 3, and use a tool to insert into the hexagonal concave structure surface of one end of the drive screw 5-5 in the outer slots 7 on both sides of the main frame 1. Tighten the drive screw 5-5 to move the pressure block 5-6 that is threadedly connected to it and slides on the inner rod 5-2. The pressure block 5-6 pushes the clamping block 5-4 in the through 5-3. The clamping layer 5-8 on the side end face of the clamping block 5-4 clamps the cable in the main slot 3. The surface curvature of the clamping block 5-4 of the clamping layer 5-8 is the same as the surface curvature of the main slot 3, which can better wrap the cable. Attach the sub-frame 2 to the bottom of the main frame 1, and fix the sub-frame 2 by screwing the bolt 6-2 inserted in the sub-frame 2 into the threaded groove 6-1 opened on the bottom surface of the main frame 1. At the same time, the cable is clamped by the cooperation of the sub-slot 4 and the main slot 3.
