Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mutual inductors, in particular to a low-voltage mutual inductor. Background Art
[0002] Low voltage transformers are industrially used AC transformers below 1KV and above 36V, including low voltage current transformers and low voltage voltage transformers. There are many varieties of low voltage transformers. Transformers are instrument transformers, which are the general term for current transformers and voltage transformers. They can convert high voltage into low voltage and large current into small current, and are used for measurement or protection systems. Their main function is to convert high voltage or large current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated values) in proportion, so as to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, transformers can also be used to isolate high voltage systems to ensure the safety of people and equipment.
[0003] However, in the application process of the low-voltage transformer currently available on the market, due to the lack of auxiliary anti-slip and anti-slip structures on the inner side of the wire passing port of the low-voltage transformer itself, the wires are easily dislodged inside the low-voltage transformer, making the application and maintenance operations very inconvenient. Utility Model Content
[0004] The utility model provides a low voltage transformer to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A low-voltage transformer comprises a low-voltage transformer and a wire fixing mechanism, wherein a through hole is penetrated in the middle of the low-voltage transformer, and mounting grooves are provided at the top, bottom and both sides of the through hole, and a plurality of card-embedded strips are provided on the inner wall surfaces of the plurality of mounting grooves, and the wire fixing mechanism also comprises a support ring, and a plurality of wire fixing plates are provided in the support ring, and a plurality of corrugated support plates are connected between the plurality of wire fixing plates and the support ring, and mounting blocks used to cooperate with the mounting grooves are provided at the top, bottom and both sides of the support ring, and a plurality of card-embedded grooves are provided on the surfaces of the plurality of mounting blocks, and wire passing openings for passing wires are formed between the plurality of wire fixing plates.
[0007] Preferably, the plurality of wire fixing plates are all arc-shaped structures.
[0008] Preferably, the wire fixing mechanism is made of an integrated structure of rubber material.
[0009] Preferably, the surfaces of the plurality of wire fixing plates are provided with anti-slip grooves.
[0010] Beneficial Effects
[0011] The above one or more technical solutions in a low voltage transformer provided by the embodiment of the utility model have at least one of the following technical effects:
[0012] Through the above technical scheme, the low-voltage transformer is provided with a wire fixing mechanism, and the wire fixing mechanism is embedded in the through hole in the middle of the low-voltage transformer. The wire passes through the wire passing opening formed by a combination of several wire fixing plates, so that after the wire passes through the wire passing opening, the wire can be clamped by the collapsible and deformable corrugated support plate and the wire fixing plate to prevent the wire from easily moving out, thereby preventing the wire from moving out of the low-voltage transformer, greatly improving the convenience of application and maintenance operations.

[0021] like Figure 1-3 As shown, it is a structural schematic diagram of a low-voltage transformer in a preferred embodiment of the utility model;
[0022] In this embodiment, a low-voltage transformer 1 and a wire fixing mechanism 2 are included. A through hole 3 is provided in the middle of the low-voltage transformer 1. The through hole 3 is used to install the wire fixing mechanism 2. The top, bottom and both sides of the through hole 3 are provided with mounting grooves 4. The inner wall surfaces of several mounting grooves 4 are integrally provided with several card filler strips 5. The wire fixing mechanism 2 also includes a support ring 6. The support ring 6 is used to constitute the main structure of the wire fixing mechanism 2 and has a supporting and connecting function. Several wire fixing plates 7 are provided in the support ring 6. Several wire fixing plates 7 are used to fit and clamp the wires to prevent the wires from being dislodged. Several of the wire fixing plates 7 are connected to the support ring 6. There are several corrugated support plates 8, which support several wire fixing plates 7. Several corrugated support plates 8 connect several wire fixing plates 7 with support rings 6. The top, bottom and both sides of the support ring 6 are provided with mounting blocks 9 used in conjunction with the mounting grooves 4. The mounting blocks 9 are embedded in the mounting grooves 4. Several surfaces of the mounting blocks 9 are provided with several card-embedded grooves 10. Several card-embedded strips are embedded in the card-embedded grooves 10 to fix the wire fixing mechanism 2 in the through hole 3. A wire passing opening 11 for passing the wire is formed between the several wire fixing plates 7, and the wire passing opening 11 is used to pass the wire.
[0023] In this embodiment, the plurality of wire fixing plates 7 are all arc-shaped structures, which can better wrap and fit the wires, and the plurality of wire fixing plates 7 are split structures, so that the wire fixing plates 7 can expand outward and adapt to wires with larger wire diameters.

[0025] In this embodiment, the surfaces of several wire fixing plates 7 are provided with anti-skid grooves 12. The anti-skid grooves 12 strengthen the friction force on the surface of the wire fixing plates 7, thereby increasing the friction force between the wires and the wire fixing plates 7, further ensuring the anti-skid effect on the wires.
