[0002] Low-voltage transformers are important devices in the power system, mainly used to convert high-voltage electricity into safe and usable low voltage. It is usually installed in a substation or distribution box. Through the principle of electromagnetic induction, the voltage from the high-voltage power grid is reduced to a standard voltage suitable for household, commercial or industrial use (such as 220V). Low-voltage transformers are not only voltage converters, but may also integrate functions such as current measurement, protection and electric energy metering to ensure the safe transmission and effective use of electricity.

[0003] In the prior art, during the installation process of the connecting wires in a low-voltage transformer, the conductive wire cores of the connecting wires may come into contact with other parts due to pulling or winding, thus causing short circuits or other circuit problems. In view of the above problems, the technical personnel in this field have proposed an outlet positioning device for low-voltage transformers to solve the above problems. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an outlet positioning device for low-voltage transformers, aiming to improve the problem that during the installation process of the connecting wires, the conductive wire cores of the connecting wires may come into contact with other parts due to pulling or winding.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An outlet positioning device for low-voltage transformers includes a transformer body. On the left and right sides of the front end of the transformer body, ear seats are fixedly connected. On the left and right sides of the top of the transformer body, fixing seats are fixedly connected. On the left and right sides of the top of the transformer body, wiring screws are arranged. Inside the fixing seats, connecting wires are slidably connected. Inside the fixing seats, two installation grooves are opened. On the inner wall of the installation grooves, a first spring is fixedly connected. On the outer side of the first spring, a first limiting block is fixedly connected. On the outer side of the first limiting block, a connecting block is fixedly connected. On the outer side of the connecting block, a resisting block is fixedly connected. On the top of the transformer body, a protective cover is rotatably connected. Inside the protective cover, a buckle assembly is arranged, and the buckle assembly plays a fixing role for the protective cover.

[0007] Further, the buckle assembly includes two limiting grooves which are respectively arranged on the left and right sides inside the protective cover. A second spring is fixedly connected to the inner wall of each limiting groove. A second limiting block is fixedly connected to the separating side of each of the two second springs. A clamping block is fixedly connected to the separating side of each of the two second limiting blocks. Clamping grooves are respectively arranged on the left and right sides inside the current transformer body. A pulling rope is fixedly connected to the adjacent side of each of the two second limiting blocks. The adjacent ends of the two pulling ropes are fixedly connected to a rotating rod.

[0008] Further, the outer part of the connecting wire is wound around the outer part of the wiring screw, and the inner part of the installation groove is slidably connected to the outer part of the first limiting block.

[0009] Further, the inner part of the installation groove is slidably connected to the outer part of the connecting block, and the inner part of the fixed seat is slidably connected to the outer part of the resisting block.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, when the connecting wire is placed on the fixed seat, the connecting wire presses the resisting block to move inwards. The resisting block drives the connecting block to move, and the connecting block drives the first limiting block to move. Through the elastic action of the first spring, the connecting wire can be conveniently fixed on the fixed seat, thereby effectively preventing the connecting wire from moving or loosening due to external vibration or pulling, ensuring the reliability and stability of the circuit connection, and preventing the winding of the connecting wire, as well as preventing the fracture of the wire core or insulation wear.

[0025] Next, in combination with the attached drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a low-voltage transformer outgoing line positioning device, including a transformer body 1, ear seats 2 are fixedly connected to both the left and right sides of the front end of the transformer body 1, fixed seats 3 are fixedly connected to both the left and right sides of the top of the transformer body 1, wiring screws 4 are arranged on both the left and right sides of the top of the transformer body 1, a connecting wire 5 is slidably connected inside the fixed seat 3, and the outside of the connecting wire 5 is wound around the outside of the wiring screw 4.

[0027] Specifically, the current transformer body 1 can be fixed on the installed substrate or mounting bracket through the ear seats 2. Through the fixing seat 3 on the current transformer body 1, the connecting wire 5 can be guided to prevent the connecting wires 5 from being wound around each other. The connecting wire 5 is wound around the wiring screw 4 on the current transformer body 1, so that the wiring screw 4 connects the conductor of the connecting wire 5 to the circuit board or electrical connection part inside the current transformer body 1, ensuring that the current can be transmitted normally.

[0028] Referring to Figure 3 and Figure 4 , two installation grooves 6 are formed inside the fixing seat 3. A first spring 7 is fixedly connected to the inner wall of the installation groove 6. A first limiting block 8 is fixedly connected to the outer side of the first spring 7. The inner part of the installation groove 6 is slidably connected to the outer part of the first limiting block 8. A connecting block 9 is fixedly connected to the outer side of the first limiting block 8. The inner part of the installation groove 6 is slidably connected to the outer part of the connecting block 9. A resisting block 10 is fixedly connected to the outer side of the connecting block 9. The inner part of the fixing seat 3 is slidably connected to the outer part of the resisting block 10. The outer part of the connecting wire 5 abuts against the outer part of the resisting block 10. A protective cover 11 is rotatably connected to the top end of the current transformer body 1.

[0029] Specifically, the installation groove 6 and the first limiting block 8 fix the first spring 7, enabling the first spring 7 to stably undergo elastic deformation. The installation groove 6 limits the first limiting block 8 and the connecting block 9, ensuring that the first limiting block 8 and the connecting block 9 do not deviate when moving. The fixing seat 3 limits the resisting block 10, enabling the resisting block 10 to move stably. Since the upper side of the resisting block 10 is arc-shaped, the connecting wire 5 can squeeze the resisting block 10 to move inward. Since the protective cover 11 is rotatable on the current transformer body 1, the connection part of the wiring screw 4 and the connecting wire 5 can be protected.

[0030] Referring to Figure 5 and Figure 6, a buckle assembly 12 is arranged inside the protective cover 11, and the buckle assembly 12 plays a fixing role for the protective cover 11. The buckle assembly 12 includes two limiting grooves 1201, which are respectively opened on the left and right sides inside the protective cover 11. A second spring 1202 is fixedly connected to the inner wall of the limiting groove 1201. A second limiting block 1203 is fixedly connected to the separating side of the two second springs 1202. The inside of the limiting groove 1201 is slidably connected to the outside of the second limiting block 1203. A clamping block 1204 is fixedly connected to the separating side of the two second limiting blocks 1203. The inside of the limiting groove 1201 is slidably connected to the outside of the clamping block 1204. Clamping grooves 1205 are respectively opened on the left and right sides inside the transformer body 1. The outside of the clamping block 1204 is engaged with the inside of the clamping groove 1205. A pulling rope 1206 is fixedly connected to the adjacent side of the two second limiting blocks 1203. The inside of the protective cover 11 is slidably connected to the outside of the pulling rope 1206. A rotating rod 1207 is fixedly connected to the adjacent ends of the two pulling ropes 1206. The inside of the protective cover 11 is rotatably connected to the outside of the rotating rod 1207.

[0031] Specifically, the limiting groove 1201 and the second limiting block 1203 play a fixing role for the second spring 1202, so that the second spring 1202 can be stable when undergoing elastic deformation. The limiting groove 1201 plays a limiting role for the second limiting block 1203 and the clamping block 1204, so that the second limiting block 1203 and the clamping block 1204 will not deviate when moving. Through the engagement of the clamping block 1204 with the clamping groove 1205, the position of the protective cover 11 is fixed. The protective cover 11 plays a limiting role for the pulling rope 1206 and the rotating rod 1207, so that the pulling rope 1206 can be stable when moving and the rotating rod 1207 can be stable when rotating. By rotating the rotating rod 1207, the two pulling ropes 1206 are driven to move towards the adjacent side, thereby driving the second limiting block 1203 to move with it, and further driving the clamping block 1204 to move with it, so that the clamping block 1204 and the clamping groove 1205 are disengaged, and then the connection between the wiring screw 4 and the connecting wire 5 can be conveniently maintained.

[0032] Working principle: When it is necessary to fix the connecting wire 5, by placing the connecting wire 5 on the fixing seat 3 and squeezing the resisting block 10 to move inward, the connecting block 9 is driven to move with it, and then the first limiting block 8 is driven to move with it, thereby squeezing the first spring 7 to undergo elastic deformation. After the connecting wire 5 is placed at the innermost side of the fixing seat 3, through the reset movement of the first spring 7, the first limiting block 8 is driven to move outward, and then the connecting block 9 is driven to move with it, and then the resisting block 10 is driven to move with it, so that the connecting wire 5 is limited and fixed on the fixing seat 3;

[0033] In addition, when maintenance is required for the connection between the wiring screw 4 and the connecting wire 5, the two pulling ropes 1206 are driven to move towards the adjacent side by rotating the rotating rod 1207, thereby driving the second limiting block 1203 to move with it, further squeezing the second spring 1202 to undergo elastic deformation, thereby driving the clamping block 1204 to move with it, and further causing the clamping block 1204 to disengage from the clamping groove 1205, so as to open the protective cover 11 to maintain the connection. After the maintenance is completed, by placing the lower side of the protective cover 11 inside the transformer body 1, the second spring 1202 undergoes a reset movement, thereby driving the two second limiting blocks 1203 to move away from each other, thereby driving the clamping block 1204 to move with it into the clamping groove 1205, and further causing the clamping block 1204 to engage with the clamping groove 1205, so as to fix the position of the protective cover 11, and further complete the maintenance of the connection.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
