Description

Technical Field

[0001] This utility model relates to the technical field of small transformers, specifically to a wiring fixing structure for a small transformer. Background Technology

[0002] Small transformers refer to transformers with a capacity of less than 10KVA. They are mainly used in low-voltage, low-current applications, such as household appliances, lighting equipment, and electronic equipment. The core is the core component of the transformer, made of stacked silicon steel sheets, and is used to provide a magnetic flux path. The windings are an important part of the transformer, made of wires, and are used to change voltage and current.

[0003] The loose wiring of small transformers can cause wires to become loose or detached, leading to poor contact and potentially affecting the transformer's performance and safety. Wires may also come into contact with other wires or components, posing a significant short-circuit safety hazard and resulting in poor performance. To address these issues, a wiring fixing structure for small transformers is disclosed in existing technology (application number CN202323372049.3, application date 2023-12-12). This fixing structure uses two detachable fixing components to connect and bend the wires connected to the small transformer, placing them between a fixing plate and a cover plate to form a clamping structure for fixation. This prevents external wiring from bending, improves safety and reliability, facilitates maintenance of external wiring, and makes the transformer more aesthetically pleasing and tidy, reducing wire clutter. Furthermore, the structure is simple and easy to operate.

[0004] Although the above-mentioned device can avoid poor contact, it still has some shortcomings in actual use. For example, when making a connection, the clamping mechanism is used to prevent the external circuit from bending, but when the electronic product is in use, it is very easy for it to fall off due to vibration.

[0005] Therefore, we proposed a wiring and fixing structure for small transformers that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a wiring fixing structure for a small transformer, so as to solve the problem that the wiring fixing structure currently on the market mentioned in the background art is prone to falling off due to vibration when connected, even though the clamping mechanism is used to prevent the external wires from bending.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wiring fixing structure for a small transformer, comprising a small transformer body and a protective shell fixed to the outside of the small transformer body, wherein the surface of the small transformer body is open, four sets of pin bodies are welded to the bottom of the small transformer body, and a connecting end is fixed to the top of the small transformer body; five sets of connecting grooves are provided at the top of the connecting end, and a snap-fit ​​mechanism is provided inside the connecting groove. The snap-fit ​​mechanism allows the wire to extend into the interior of the connecting conductor to prevent the wire from falling off. An auxiliary disassembly and assembly mechanism is provided at the upper end of the connecting groove, which can fully limit the position of the chuck.

[0008] As a preferred technical solution of this application, the latching mechanism includes a return spring fixed at the bottom of the inner end of the connecting conductor, the top end of the return spring being fixed at the bottom of the chuck, the outer side of the chuck being slidably disposed inside the connecting conductor, and a latching hole being formed through the surface of the chuck.

[0009] As a preferred technical solution of this application, the bottom position of the chuck is slidably disposed inside the connecting conductor, and the chuck forms an elastic sliding structure with the interior of the connecting conductor through a return spring.

[0010] As a preferred technical solution of this application, a hole is provided on the surface of the connecting conductor, and the diameter of the hole is the same as the diameter of the card hole.

[0011] As a preferred technical solution of this application, the auxiliary disassembly and assembly mechanism includes guide grooves opened on the left and right side walls of the connecting end. A slider is fitted inside the guide groove. The top of the slider is fixed to one side of the fitting block, and the outer side of the slider is fixed to one side of the hand lever block. The upper inner side of the fitting block is connected to the top of the connecting end through a connecting spring.

[0012] As a preferred technical solution of this application, the lower protruding position of the bonding block extends into the inner wall of the connecting groove, and the protruding bottom position of the bonding block is attached to the top position of the chuck.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The wiring fixing structure of this small transformer is equipped with a snap-fit ​​mechanism, which can limit the wires and prevent them from falling off during use. In addition, the auxiliary disassembly mechanism can effectively loosen the snap-fit ​​mechanism, facilitating disassembly with the addition of guides later. The specific details are as follows:

[0014] 1. A connecting conductor is provided. Through the hole opened on the surface of the connecting conductor, the wire can be inserted into the hole and the chuck hole opened inside. Through the pin body fixed at the bottom of the small transformer body, the small transformer body can be energized through two sets of connections. Furthermore, a reset spring is provided. The chuck is driven by the reset spring to reset the chuck hole inside the connecting conductor, thereby realizing the limiting treatment of the wire.

[0015] 2. A bonding block is provided. The bottom protrusion of the bonding block is slidably positioned inside the connecting groove. The bonding block can slide inside the guide groove by the setting of the hand lever. The connecting spring fixed inside the bonding block will drive the bonding block to press against the top position of the chuck, so that the chuck hole and the hole opened on the surface of the connecting conductor are at the same level, which facilitates the replacement of the wire later.

[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 1-6 The present invention provides the following technical solution: a wiring fixing structure for a small transformer.

[0025] Example 1: Currently available wiring fixing structures use clamping mechanisms to prevent external wiring from bending. However, during use of electronic products, these structures are prone to detachment due to vibrations. Please refer to the attached diagram. Figure 1 -Appendix Figure 3 and attached Figure 5 The system includes a small transformer body 1 and a protective shell 2 fixed to the outside of the small transformer body 1. The surface of the small transformer body 1 is open. Four sets of pin bodies 3 are welded to the bottom of the small transformer body 1, and a connecting end 4 is fixed to the top of the small transformer body 1. Five sets of connecting grooves 5 are opened at the top of the connecting end 4. A latching mechanism is set inside the connecting grooves 5. The latching mechanism allows the wire to be inserted into the interior of the connecting conductor 6 to prevent the wire from falling off. The latching mechanism includes a return spring 7 fixed to the bottom of the interior of the connecting conductor 6. The top of the return spring 7 is fixed to the bottom of the chuck 8. The outside of the chuck 8 is slidably disposed inside the connecting conductor 6. A latching hole 9 is opened through the surface of the chuck 8. The bottom of the chuck 8 is slidably disposed inside the connecting conductor 6, and the chuck 8 forms an elastic sliding structure with the interior of the connecting conductor 6 through the return spring 7. A hole is opened on the surface of the connecting conductor 6, and the diameter of the hole is the same as the diameter of the latching hole 9.

[0026] First, when connecting the wires of the small transformer body 1, by pressing the hand levers 13 at both ends of the bonding block 12, the protruding part of the bonding block 12 can be pressed against the top of the chuck 8, which makes it easy for the chuck hole 9 and the hole of the connecting conductor 6 to be at the same level. Then, one end of the wire is inserted into the chuck hole 9 and the hole of the connecting conductor 6. At this time, by using the bonding block 12, the chuck 8 will be reset by the elasticity of the return spring 7. The chuck 8 will drive the chuck hole 9 and the wire inside the chuck hole 9 to move. Thus, by the misalignment of the chuck hole 9 and the hole, the wire can be limited.

[0027] Example 2: This example differs from Example 1 in that it provides further auxiliary processing to the latching mechanism to prevent detachment. Please refer to the attached document. Figure 1 and attached Figure 4 -Appendix Figure 6An auxiliary disassembly and assembly mechanism is provided at the upper end of the connecting groove 5. The auxiliary disassembly and assembly mechanism can fully limit the position of the chuck 8. The auxiliary disassembly and assembly mechanism includes guide grooves 10 opened on the left and right side walls of the connecting end 4. A slider 11 is fitted inside the guide groove 10. The top of the slider 11 is fixed to one side of the fitting block 12, and the outer side of the slider 11 is fixed to one side of the hand lever block 13. The upper inner side of the fitting block 12 is connected to the top of the connecting end 4 through a connecting spring 14. The lower protruding part of the fitting block 12 extends into the inner wall of the connecting groove 5, and the bottom of the protruding part of the fitting block 12 is fitted to the top of the chuck 8.

[0028] When replacing the wire, the hand lever 13 is manually moved, causing it to slide inside the guide groove 10 and move the bonding block 12. At this time, the protruding part at the bottom of the bonding block 12 will press the top of the chuck 8, so that the card hole 9 inside the chuck 8 and the hole on the surface of the connecting conductor 6 are at the same level, which can ensure the replacement of the wire later.
