Description

Technical Field

[0001] This utility model relates to the field of automatic wiring device technology, and more specifically, to an automatic wiring device for a current transformer. Background Technology

[0002] A current transformer is an instrument that measures a large primary current by converting a small secondary current into a large primary current based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Current transformers are divided into two main categories: electromagnetic current transformers and electronic current transformers. Therefore, it often carries the entire current of the circuit. The secondary winding has a relatively large number of turns and is connected in series in the measuring instrument and protection circuit. When the current transformer is working, its secondary circuit is always closed. Therefore, the impedance of the series coil of the measuring instrument and protection circuit is very small, and the working state of the current transformer is close to a short circuit.

[0003] Currently, the wiring of current transformers is mostly done by manually rotating bolts to squeeze the wire connection terminals inserted into the installation position to achieve the function of fixing the wiring. However, fixing by squeezing by rotating bolts is prone to loosening or even falling off the terminals due to external pulling or rotation of the bolts, affecting the connection effect and making it inconvenient to automatically fix the wiring after the wire is inserted. Therefore, an automatic wiring device for current transformers is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic wiring device for current transformers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic wiring device for a current transformer, comprising a wiring box, a current transformer body connected to one side of the wiring box, a wiring socket provided on one side of the wiring box, a start button provided on the side of the wiring box away from the current transformer body, a controller provided in the middle of the wiring box, and a baffle fixedly connected to the top of the opening of the wiring socket.

[0006] A movable baffle is rotatably connected to the top opening of the inner cavity of the wiring socket. One end of the movable baffle is provided with anti-slip teeth. A plug plate is inserted into the top of the wiring box. A pull plate and a limiting plate are fixedly connected to both ends of the plug plate, and a connecting cloth strip and a spring are connected to both sides of the limiting plate, respectively.

[0007] A sensor is located at the center of the top of the inner cavity of the wiring socket. A pressing plate is located on the side of the sensor away from the movable baffle. An electric push rod is located on the top of the pressing plate.

[0008] Preferably, the controller and the wiring socket are in one-to-one correspondence, the plug plate and the wiring socket are in one-to-one correspondence, and one end of the connecting cloth strip is fixedly connected to one side wall of the movable baffle.

[0009] Preferably, the movable baffle has a second inclined surface at the end near the anti-slip teeth, and a limiting groove at the end away from the second inclined surface, the limiting groove corresponding to the baffle.

[0010] Preferably, the two side walls of the pull plate are configured as arc-shaped structures, and the springs are disposed on both sides of the insert plate.

[0011] Preferably, the moving end of the electric push rod is fixedly connected to an extrusion plate, the bottom wall of the extrusion plate is set as an inclined surface, and a second anti-slip groove is provided at the bottom inclined surface of the extrusion plate.

[0012] Preferably, the bottom of the inner cavity of the wiring socket is provided with a first inclined surface located directly below the extrusion plate, and the surface of the first inclined surface is provided with a first anti-slip groove, which is located directly below the extrusion plate.

[0013] Preferably, the extrusion plate is made of a conductive material, the extrusion plate is connected to the current transformer body via a wire, and the controller is electrically connected to the electric push rod and the sensor via a wire.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model firstly uses a movable baffle to automatically fix the wire when it is inserted, preventing the wire from falling off due to pulling. A sensor detects whether the wire is inserted and the controller activates an electric push rod to squeeze the wire's terminal with a pressing plate. The cooperation of the second and first anti-slip grooves improves the connection strength and prevents the wire from loosening or falling off due to pulling. This improves the connection strength and prevents loosening, thus achieving automatic wire fixing after insertion and improving the connection effect.

[0016] 2. This utility model also allows manual control of the electric push rod by pressing the start button to drive the extrusion plate to move upward, facilitating the separation of the top wire. By pulling the pull plate and the connecting cloth strip pulling the movable baffle, one end of the movable baffle is lifted upward, making it easy to pull the wire out from the inside of the wiring socket. With the cooperation of the second inclined surface and the second anti-slip groove, when the wire is inserted, it hangs down naturally through one end of the movable baffle, which can prevent the wire from falling off and improve the connection strength.

[0017] In summary, through the interaction of the above-mentioned functions, the wiring can be automatically fixed after the wire is inserted, improving the prevention of loosening and falling off, increasing the connection strength, facilitating the disassembly and secondary wiring, and improving the overall performance.

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.

[0025] As attached Figure 1-5 An automatic wiring device for a current transformer is shown, including a wiring box 2. A current transformer body 1 is connected to one side of the wiring box 2. A wiring socket 5 is provided on one side of the wiring box 2 to facilitate the insertion of the wire end. A start button 4 is provided on the side of the wiring box 2 away from the current transformer body 1. A controller 3 is provided in the middle of the wiring box 2. A baffle 6 is fixedly connected to the top of the opening of the wiring socket 5. The start button 4 and the controller 3 work together to facilitate the start of the electric push rod 18.

[0026] A movable baffle 10 is rotatably connected to the top opening of the inner cavity of the wiring socket 5. One end of the movable baffle 10 is provided with anti-slip teeth 11. A plug plate 12 is inserted into the top of the wiring box 2. A pull plate 13 and a limiting plate 14 are fixedly connected to both ends of the plug plate 12, respectively. A connecting cloth strip 15 and a spring 16 are connected to both sides of the limiting plate 14, respectively. The movable baffle 10 can block the opening of the wiring socket 5 vertically, which plays a protective role. By pulling the pull plate 13, the plug plate 12 drives the limiting plate 14 to squeeze the spring 16. The connecting cloth strip 15 pulls the movable baffle 10, which can move the movable baffle 10 upward, making it easy to take out the connecting wire. The anti-slip teeth 11 at one end of the movable baffle 10 can prevent the wire from falling out after it is inserted, thus improving the connection strength.

[0027] A sensor 9 is located at the top center of the inner cavity of the wiring socket 5. A pressing plate 17 is located on the side of the sensor 9 away from the movable baffle 10. An electric push rod 18 is located on the top of the pressing plate 17. The sensor 9 senses whether a wire is inserted into the wiring socket 5, and the pressing plate 17 is moved downward by activating the electric push rod 18. This can press and fix the conductive end of the wire connection, making it convenient for connection and use.

[0028] As attached Figure 1 , 2 As shown, the controller 3 and the wiring socket 5 correspond one-to-one, the plug plate 12 and the wiring socket 5 correspond one-to-one, one end of the connecting strip 15 is fixedly connected to one side wall of the movable baffle 10, the controller 3 can easily control the start of the electric push rod 18, thereby controlling the position of the extrusion plate 17, and the connecting strip 15 can be pulled by the limiting plate 14, which can pull one end of the movable baffle 10 upward, making it easy to disassemble the connecting wire.

[0029] As attached Figure 2-4 As shown, the movable baffle 10 has a second inclined surface 20 at one end near the anti-slip teeth 11, and a limiting groove 19 at the other end away from the second inclined surface 20. The limiting groove 19 corresponds to the baffle 6. Through the cooperation of the limiting groove 19 and the baffle 6, the rotation position of the movable baffle 10 is limited. The second inclined surface 20 increases the support area of ​​the movable baffle 10 for the bottom wire, and the anti-slip teeth 11 improve the anti-slip effect of the wire at the bottom of the movable baffle 10, thereby improving the connection strength.

[0030] As attached Figure 1 , 2 As shown in Figure 4, the two side walls of the pull plate 13 are set as arc-shaped structures, and the springs 16 are set on both sides of the insert plate 12 to facilitate the pull plate 13 to be pulled and the limiting plate 14 is pushed by the springs 16, so that the movable baffle 10 is vertically set inside the wiring socket 5 when it is not pushed.

[0031] As attached Figure 2 ,5 As shown, the moving end of the electric push rod 18 is fixedly connected to the extrusion plate 17. The bottom wall of the extrusion plate 17 is set as an inclined surface. A second anti-slip groove 21 is provided at the bottom inclined surface of the extrusion plate 17. When the electric push rod 18 is activated, the extrusion plate 17 is controlled to move downward, which can extrude the connection end of the wire. The second anti-slip groove 21 improves the anti-slip strength of the extrusion, thereby improving the connection strength.

[0032] As attached Figure 2 , 3 As shown, the bottom of the inner cavity of the wiring socket 5 is provided with a first inclined surface 7 located directly below the extrusion plate 17. The surface of the first inclined surface 7 is provided with a first anti-slip groove 8. The first anti-slip groove 8 is located directly below the extrusion plate 17. The first inclined surface 7 guides and supports the inserted wire connection end, and the first anti-slip groove 8 increases the extrusion and fixing strength of the wire connection end, thereby improving the anti-detachment effect.

[0033] As attached Figure 2 As shown, the extrusion plate 17 is made of conductive material. The extrusion plate 17 is connected to the current transformer body 1 through wires. The controller 3 is electrically connected to the electric push rod 18 and the sensor 9 through wires. The extrusion plate 17 facilitates the electrical connection of the wires to the current transformer body 1, and the controller 3 facilitates the control of the electric push rod 18 to start.

[0034] The working principle of this utility model is as follows: When in use, simply insert the connecting end of the wire into the inside of the wiring socket 5 and push the movable baffle 10 until the connecting end of the wire is at the top of the first inclined surface 7. At this time, when the sensor 9 senses the top wire, the controller 3 controls the electric push rod 18 to start, so that the pressing plate 17 moves downward to press the connecting end of the wire, thereby achieving automatic connection. At the same time, the movable baffle 10 tilts and is combined with the anti-slip teeth 11 to prevent the inserted wire from falling off and improve the connection strength.

[0035] When disassembling, press the start button 4 to control the electric push rod 18 to start the squeezing plate 17 to move upward, and then pull the pull plate 13 to move one end of the movable baffle 10 upward, so that the wire can be pulled out, improving the use effect.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
