Description

Technical Field

[0001] This utility model relates to the field of transformer equipment technology, specifically a transformer with cable clamping function. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] A search revealed Chinese patent application number CN202322999709.4, which relates to the field of transformer technology, specifically a transformer with cable clamping function. The transformer includes a transformer body with a mounting plate fixedly installed at its top. Multiple low-voltage output terminals are uniformly fixedly installed on one side of the top of the mounting plate, and multiple high-voltage output terminals are uniformly fixedly installed on the other side. A protective component is also provided at the top of the mounting plate. This utility model protects both the low-voltage and high-voltage output terminals through the protective plate, improving their safety and providing protection against rain, snow, and hail. It also enhances the safety of wiring between the low-voltage and high-voltage output terminals. Clockwise rotation of the turntable causes the threaded column to rotate within the threaded hole, while the arc-shaped clamping plate slides downwards simultaneously, securing the cable within the clamping cylinder and improving the stability of the cable connection, thus benefiting cable usage.

[0004] Existing transformers may require the connection of multiple cables. When multiple cables are connected, conventional cable clamping devices cannot flexibly adjust the slack of the clamping. If the clamping is too tight, it will damage the cables; if it is too loose, it will not be able to restrict the displacement of the cables. Therefore, we need to propose a transformer with cable clamping function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a transformer with a cable clamping function. By adding a cable clamping component, when one or more cables are connected to the cable connection component, they are fixed to the cable connection component by a fixing strip. Through the characteristics of the spring, the clamping clip is pushed towards the cable. The cable connection component and the clamping clip clamp the cable, allowing the device to flexibly adjust the clamping force on the cable. While clamping the cable, the device will not damage the cable, thereby improving the practicality of the device and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transformer with cable clamping function, comprising a transformer body, a cable protection box installed on the transformer body, a cable connection assembly installed inside the cable protection box, and a cable clamping assembly installed on the cable connection assembly;

[0007] The cable clamping assembly includes a fixing bar, a sliding sleeve embedded in the fixing bar, a guide rod slidably connected inside the sliding sleeve, a clamping clip fixed at one end of the guide rod, and a spring fixed between the clamping clip and the fixing bar.

[0008] Preferably, the cable connection assembly includes a junction box, an insulating terminal block is installed inside the junction box, a terminal post is provided on the insulating terminal block, and an insulating nut is threaded onto the terminal post.

[0009] Preferably, the cable connection assembly further includes a connector ring, which is sleeved on the terminal block and located between the insulating terminal block and the insulating nut.

[0010] Preferably, a terminal clamp is installed at the lower end of the wiring ring, a cable is fixed on the terminal clamp, a clamping seat is fixed on the insulating terminal block, and the cable is clamped between the clamping seat and the clamping clamp.

[0011] Preferably, the junction box has a wire hole at its lower end and a screw hole at its front end.

[0012] Preferably, the fixing strip has countersunk holes at both ends, and bolts are installed in the countersunk holes. The fixing strip is fixed to the junction box by the cooperation of bolts, countersunk holes and screw holes.

[0013] Preferably, the transformer body is equipped with multiple sets of heat dissipation plates, the cable protection box is rotatably connected to a door via a hinge, and the door and the cable protection box are equipped with a lock.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention incorporates a cable clamping component. When one or more cables are connected to the cable connection component, they are secured to the component by a fixing strip. The spring's properties push the clamping clips towards the cables, clamping them together with the clamping base and clamping clips. This allows for flexible adjustment of the clamping force, ensuring that the cables are clamped without damage, thus improving the device's practicality. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a transformer with cable clamping function, including a transformer body 100, a cable protection box 200 installed on the transformer body 100, a cable connection assembly 300 installed inside the cable protection box 200, and a cable clamping assembly 400 installed on the cable connection assembly 300.

[0022] The cable clamping assembly 400 includes a fixing bar 401, on which a sliding sleeve 404 is embedded. A guide rod 406 is slidably connected inside the sliding sleeve 404. One end of the guide rod 406 is fixed with a clamping clip 405. The guide rod 406 restricts the clamping clip 405 to move only in one direction, preventing the clamping clip 405 from shifting, which would prevent the clamping clip 405 from cooperating with the clamping clip seat 305 to clamp the cable 313. A spring 407 is fixed between the clamping clip 405 and the fixing bar 401.

[0023] When one or more cables 313 are connected to the cable connection assembly 300, they are fixed to the junction box 301 by the fixing strip 401. Due to the characteristics of the spring 407, the clamping clip 405 is pushed towards the cable 313. The clamping clip 405 and the clamping clip 405 clamp the cable 313, so that the device can flexibly adjust the clamping force on the cable 313. The device can clamp the cable 313 without damaging it, thereby improving the practicality of the device.

[0024] The cable connection assembly 300 includes a junction box 301, an insulating terminal block 302 installed inside the junction box 301, a terminal block 303 provided on the insulating terminal block 302, and an insulating nut 306 threaded onto the terminal block 303. During installation, a terminal ring 311 is fitted onto the terminal block 303, and then the insulating nut 306 is screwed on, so that the terminal ring 311 is clamped between the insulating terminal block 302 and the insulating nut 306, thereby completing the fixation of the cable 313.

[0025] The cable connection assembly 300 also includes a connector ring 311, which is sleeved on the terminal block 303 and located between the insulating terminal block 302 and the insulating nut 306, so as to facilitate the fixing of the cable 313 with the connector ring 311 installed.

[0026] The lower end of the connector ring 311 is equipped with a terminal clamp 312, which facilitates the quick installation of the connector ring 311 on the cable 313. The cable 313 is fixed on the terminal clamp 312. The insulating connector plate 302 is fixed with a clamping seat 305. The cable 313 is clamped between the clamping seat 305 and the clamping clip 405, which facilitates the clamping of the cable 313 during use and prevents it from shifting.

[0027] The junction box 301 has a wire hole 304 at the lower end for easy access of the cable 313, and a screw hole at the front end for easy fixing of the fixing strip 401 to the junction box 301 by using a bolt 403 in conjunction with the screw hole.

[0028] The fixing strip 401 has countersunk holes 402 at both ends, and bolts 403 are installed in the countersunk holes 402. The fixing strip 401 is fixed to the junction box 301 by the cooperation of the bolts 403, countersunk holes 402 and screw holes. After the cable 313 is connected, the clamping clip 405 is aligned with the cable 313, and then the bolts 403 are screwed on, so that the fixing strip 401 is fixed to the junction box 301, thereby completing the clamping and fixing of the cable 313.

[0029] The transformer body 100 is equipped with multiple heat dissipation plates 110, and the cable protection box 200 is connected to a door 210 by a hinge. The door 210 and the cable protection box 200 are equipped with a lock 220, which facilitates the creation of a relatively enclosed space for the cable connection assembly 300, preventing foreign objects from entering the junction box 301 and causing safety hazards.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
