Description

Technical Field

[0001] This utility model relates to the technical field of soft starter cabinet accessories, specifically a circuit connector structure for a soft starter cabinet. Background Technology

[0002] Soft starter cabinets are mainly used for starting various high-power motors. They replace traditional starting methods with soft starting, achieving smooth starting, reducing starting current, minimizing the mechanical impact on the motor and the power grid caused by the large current during motor startup, improving power quality, saving energy, and preventing motor overheating and burnout due to mechanical failure or stalling by using stall protection and fast protection. They also reduce voltage drop caused by large current. In existing soft starter cabinets, the internal circuit wiring device usually uses screw caps to press the wire ends to the outside of the terminal block. Since screwdrivers are needed for wiring, the wiring operation is cumbersome and affects the efficiency of the soft starter cabinet's circuit wiring. Therefore, we propose a circuit connector structure for soft starter cabinets. Utility Model Content

[0003] The purpose of this invention is to provide a circuit connector structure for a soft starter cabinet to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A circuit connector structure for a soft starter cabinet includes a connector body, an annular stop, a cable guide frame, and a stop bracket. A plurality of terminals are fixedly mounted on the connector body. The annular stop is fixedly mounted on the connector body and located outside the terminals. The cable guide frame is fixedly connected to both sides of the connector body via side blocks. The stop bracket is fixedly installed at both ends of the inner side of the cable guide frame. A plurality of guide grooves are formed on the surface of the stop bracket. Limit blocks are slidably connected to the guide grooves. A wire clamp is fixedly mounted at one end of each limit block. A spring is fixedly connected between the stop bracket and the wire clamp. The wire clamp is slidably sleeved onto one end of a terminal.

[0006] Preferably, the side of the cable tray has several cable entry holes, and the cable entry holes are provided corresponding to the terminal blocks.

[0007] By setting up a wire pass-through port, the wires to be connected can be passed through the pass-through port to the wire guide frame for wiring.

[0008] Preferably, the cross-sectional shape of both the limiting block and the guide groove is rectangular.

[0009] This design allows the limiting block to slide stably along the guide groove, preventing the limiting block from twisting within the guide groove.

[0010] Preferably, a handle is fixedly provided on the outer wall of the wire pressing base, and the handle has rounded corners on its side.

[0011] By incorporating a handle, it becomes easier to slide the wire clamp along the terminal block.

[0012] Preferably, two reinforcing blocks are fixedly connected between the side block and the cable tray, and the reinforcing blocks are symmetrically distributed.

[0013] By setting up reinforcing blocks, the structural strength of the connection between the side blocks and the cable tray was improved.

[0014] Preferably, a lifting lug is fixedly connected to the upper end of the cable tray, and the surface of the lifting lug is provided with mounting holes.

[0015] By setting up lifting lugs, the cable tray can be fixedly installed inside the soft starter cabinet.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention allows the wire to be connected to pass through the wire guide frame via the wire insertion port. The handle is used to pull the wire clamp along the terminal block on the connector body, where a limiting block slides along the guide groove to guide the wire. This causes the spring to gradually contract until the wire clamp detaches from the terminal block. The wire end is then placed on the terminal block. After releasing the handle, the spring forces the wire clamp to press against the wire end, allowing the wire clamp and the annular stop to firmly secure the wire end. This facilitates quick and easy wiring of the soft starter cabinet, eliminating the need for screwdrivers and making the wiring operation more convenient and simple, thus improving the efficiency of soft starter cabinet wiring.

[0023] 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.

[0024] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A circuit connector structure for a soft starter cabinet includes a connector body 1, an annular stop 102, a cable guide 2, and a stop 3. Several terminals 101 are fixedly mounted on the connector body 1. The annular stop 102 is fixedly mounted on the connector body 1 and located outside the terminals 101. The cable guide 2 is fixedly connected to both sides of the connector body 1 via side blocks 103. The stop 3 is fixedly installed at both ends of the inner side of the cable guide 2. Several guide grooves 301 are formed on the surface of the stop 3. Limit blocks 4 are slidably connected to the guide grooves 301. A wire clamp 401 is fixedly mounted at one end of the limit block 4. A spring 5 is fixedly connected between the stop 3 and the wire clamp 401. The wire clamp 401 is slidably sleeved onto one end of the terminal 101. Several wire through holes 201 are formed on the side of the cable guide 2. The wire through holes 201 connect to the terminals 101. Correspondingly, post 101 is set up. When wiring the circuit of the soft starter cabinet is required, the wire to be connected is passed through the wire pass 201 through the wire pass frame 2. The wire clamp 401 is pulled and slid along the terminal post 101 on the connector body 1. The limit block 4 slides along the guide groove 301 to guide the wire, so that the spring 5 gradually contracts until the wire clamp 401 is separated from the terminal post 101. The wire end is put on the terminal post 101, and the spring 5 drives the wire clamp 401 to press against the wire end, so that the wire clamp 401 and the annular stop 102 can press and fix the wire end. The spring 5 is a spring with a suitable elastic stiffness coefficient, so that the spring 5 has a certain stiffness damping effect to ensure that the wire clamp 401 and the annular stop 102 can press and fix the wire end, thereby producing a stable installation effect.

[0026] As a preferred embodiment of this example, Figure 3As shown, both the limiting block 4 and the guide groove 301 have rectangular cross-sectional shapes, which allows the limiting block 4 to slide stably along the guide groove 301 and prevents the limiting block 4 from twisting within the guide groove 301.

[0027] As a preferred embodiment of this example, Figure 1 As shown, a handle 402 is fixedly installed on the outer wall of the wire clamp 401. The side of the handle 402 is rounded to facilitate the sliding of the wire clamp 401 along the terminal block 101.

[0028] As a preferred embodiment of this example, Figure 4 As shown, two reinforcing blocks 6 are fixedly connected between the side block 103 and the cable tray 2. The reinforcing blocks 6 are symmetrically distributed, which achieves the purpose of improving the structural strength of the connection between the side block 103 and the cable tray 2.

[0029] As a preferred embodiment of this example, Figure 4 As shown, a lifting lug 202 is fixedly connected to the upper end of the cable tray 2. The surface of the lifting lug 202 is provided with mounting holes, so that the cable tray 2 can be fixedly installed in the soft starter cabinet.

[0030] Working principle:

[0031] During use, the cable guide 2 is fixedly installed inside the soft starter cabinet by the lifting lug 202. The wire to be connected is passed through the cable guide 2 through the cable pass 201. The handle 402 is used to pull the wire clamp 401 to slide along the terminal post 101 on the connector body 1. The limit block 4 slides along the guide groove 301 to guide, causing the spring 5 to gradually contract until the wire clamp 401 is separated from the terminal post 101. The wire end is put on the terminal post 101. After releasing the handle 402, the spring 5 drives the wire clamp 401 to press against the wire end, so that the wire clamp 401 and the annular stop 102 can press and fix the wire end. This facilitates the quick and easy wiring of the soft starter cabinet. No screwdrivers are needed for the wiring process, making the wiring operation more convenient and simple.
