[0002] Power fittings are metal accessories that connect and combine various devices in a power system and play a role in transmitting mechanical loads, electrical loads, and certain protective functions. Among them, the power fittings used for overhead transmission lines are called line fittings. Line fittings are used for connecting between conductors, between insulators, between insulators and towers, and between insulators and conductors on overhead transmission lines; they must have sufficient mechanical strength and flexibility in assembly and operation.

[0003] According to a power connection fitting with the publication number of CN202905958U, it includes: a frame-shaped main body and a wire pressing rod. The wire pressing rod is connected to the frame-shaped main body through a pressing mechanism, and a wire pressing plate is arranged at one end of the wire pressing rod. The connection method between the wire pressing rod and the frame-shaped main body can be like this. The wire pressing rod can be a bolt, and a washer is arranged between the frame-shaped main body and the wire pressing rod and is connected through a thread. The frame-shaped main body of the utility model can be in full contact with copper plates and copper bars, making the force evenly distributed, the copper plates and copper bars not easy to deform, and avoiding the phenomenon of sparking. The wire pressing rod and the frame-shaped main body are connected through a thread, so as to press the copper plates and copper bars of the wiring nose. This method has a simple structure and is easy to implement, and is supplemented by a washer to make the thread connection more firm.

[0004] Aiming at the above related solutions, the above avoids punching holes in copper plates and copper bars, so that the current-carrying area will not be lost. Although the connection method through threads is relatively stable, it will make the installation and disassembly processes more cumbersome and inconvenient, restricting its flexibility. This connection method makes the later replacement or maintenance more difficult, increasing the complexity of operation and maintenance costs. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a power fitting with high connection stability to solve the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a power fitting with high connection stability, including a frame body, a limiting mechanism is arranged inside the frame body. The limiting mechanism includes a first limiting plate, a rotating shaft, and a torsion spring. A first limiting plate is arranged on one side inside the frame body, a second limiting plate is arranged on one side of the first limiting plate inside the frame body, first connecting blocks are symmetrically arranged at the top of the second limiting plate, and a torsion spring is connected between the first connecting blocks and the frame body.

[0007] Preferably, one end of the first connecting block is provided with a rotating shaft rotatably connected to the frame body through a bearing, and two rotating shafts and torsion springs are symmetrically arranged about the central axis of the frame body.

[0008] Preferably, insulating pads are provided on the sides of the first limiting plate and the second limiting plate close to each other, and a buckling groove is formed on the outer surface of the second limiting plate.

[0009] Preferably, two second connecting blocks are symmetrically arranged about the central axis of the frame body at the bottom end of the second limiting plate.

[0010] Preferably, a reinforcement mechanism is arranged between the second connecting block and the frame body, and the reinforcement mechanism is composed of a lifting rod, a support spring, a reinforcement plate and a reinforcement groove.

[0011] Preferably, a reinforcement plate is slidably connected to one side of the frame body close to the second connecting block, a reinforcement groove is formed on one side of the second connecting block, the reinforcement plate and the second connecting block form a clamping structure through the reinforcement groove, and an inclined surface is arranged on one side of the reinforcement plate.

[0012] Preferably, a lifting rod connected to the reinforcement plate is slidably connected to the inside of the frame body, a support spring is connected between the reinforcement plate and the frame body, and the reinforcement plate and the frame body form an elastic structure through the support spring.

[0013] In summary, the present utility model mainly has the following beneficial effects:

[0014] 1. Although the existing electric power fittings are relatively stable by means of threaded connection, it will make the later replacement or maintenance more difficult, increasing the complexity of operation and maintenance costs. In the present utility model, by setting a limiting mechanism and a buckling groove, since the first connecting block is rotatably connected to the frame body through a rotating shaft and is elastically connected through a torsion spring, it is possible to make the first connecting block and the second limiting plate deflect around the rotating shaft by buckling the buckling groove, so that the line can be conveniently placed in the first limiting plate. After releasing the buckling groove, the second limiting plate will reset under the action of the torsion spring, so that the line can be stably connected through the cooperation of the first limiting plate and the second limiting plate, and at the same time, it is convenient for later disassembly and maintenance, improving the convenience of use;

[0015] 2. In the present utility model, by setting a reinforcement mechanism, since the reinforcement plate is elastically connected to the frame body through a support spring and an inclined surface is arranged at one end of the reinforcement plate close to the second connecting block, when the second connecting block rotates to the inner side of the frame body, the reinforcement plate will be clamped into the reinforcement groove under the action of the support spring, so as to realize the reinforcement of the second connecting block in the frame body and further improve the connection stability.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0023] Next, the embodiments of the present utility model will be described according to its overall structure.

[0024] A type of electrical fitting with high connection stability, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, includes a frame body 1. A limiting mechanism 2 is arranged inside the frame body 1. The limiting mechanism 2 includes a first limiting plate 201, a rotating shaft 204 and a torsion spring 205. A first limiting plate 201 is arranged on one side inside the frame body 1. A second limiting plate 202 is arranged inside the frame body 1 on one side of the first limiting plate 201. First connecting blocks 203 are symmetrically arranged at the top of the second limiting plate 202. A torsion spring 205 is connected between the first connecting blocks 203 and the frame body 1;

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4It can be seen that since the first connecting block 203 is rotatably connected to the frame body 1 through the rotating shaft 204 and is elastically connected through the torsion spring 205, the first connecting block 203 and the second limiting plate 202 can be deflected around the rotating shaft 204 by pulling the buckle groove 6, so that the circuit can be easily placed in the first limiting plate 201. After releasing the buckle groove 6, the second limiting plate 202 will reset under the action of the torsion spring 205. Therefore, the circuit can be firmly connected through the cooperation of the first limiting plate 201 and the second limiting plate 202, and it is convenient for later disassembly and maintenance, improving the convenience of use.

[0026] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 It can be seen that two second connecting blocks 4 are arranged at the bottom end of the second limiting plate 202 symmetrically about the central axis of the frame body 1. A reinforcing mechanism 5 is arranged between the second connecting block 4 and the frame body 1. The reinforcing mechanism 5 is composed of a lifting pull rod 501, a support spring 502, a reinforcing plate 503 and a reinforcing groove 504. A reinforcing plate 503 is slidably connected to one side of the frame body 1 close to the second connecting block 4. A reinforcing groove 504 is formed on one side of the second connecting block 4. The reinforcing plate 503 and the second connecting block 4 form a clamping structure through the reinforcing groove 504. An inclined surface is arranged on one side of the reinforcing plate 503. A support spring 502 is connected between the reinforcing plate 503 and the frame body 1. The reinforcing plate 503 and the frame body 1 form an elastic structure through the support spring 502;

[0027] Refer to Figure 1 and Figure 5 It can be seen that since the reinforcing plate 503 is elastically connected to the frame body 1 through the support spring 502 and an inclined surface is arranged at one end of the reinforcing plate 503 close to the second connecting block 4, when the second connecting block 4 rotates to the inner side of the frame body 1, the reinforcing plate 503 will be clamped into the reinforcing groove 504 under the action of the support spring 502, so as to realize the reinforcement of the second connecting block 4 in the frame body 1 and further improve the connection stability.

[0028] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It can be seen that insulating pads 3 are arranged on the sides of the first limiting plate 201 and the second limiting plate 202 close to each other. A buckle groove 6 is formed on the outer surface of the second limiting plate 202. By pulling the buckle groove 6, the second limiting plate 202 can be deflected around the rotating shaft 204, so that the circuit can be easily taken out or put in, improving the convenience.

[0029] Refer to Figure 1 、 Figure 4 andFigure 5 It can be seen that a lifting rod 501 connected to the reinforcing plate 503 is slidably connected inside the frame body 1. The lifting rod 501 is arranged in an inverted "T" shape. By pulling the lifting rod 501 outwards, the reinforcing plate 503 is disengaged from the reinforcing groove 504, thereby releasing the reinforcement of the second connecting block 4, so as to facilitate the installation or removal of subsequent circuits.

[0030] The working principle of the present utility model is as follows: When using the electric power fitting with high connection stability, by pulling the buckle groove 6, the first connecting block 203 and the second limiting plate 202 can be deflected around the rotation axis 204, so that it is convenient to place the circuit in the first limiting plate 201. After releasing the buckle groove 6, the second limiting plate 202 will reset under the action of the torsion spring 205, so that the stable connection of the circuit can be realized through the cooperation of the first limiting plate 201 and the second limiting plate 202. At the same time, the reinforcing plate 503 will be clamped into the reinforcing groove 504 under the action of the supporting spring 502, so as to realize the reinforcement of the second connecting block 4 in the frame body 1, further improving the connection stability.
