Description

Technical Field

[0001] This utility model relates to the field of resistor bending technology, and in particular to a resistor bending structure. Background Technology

[0002] Resistors play a variety of important roles in circuits, including protecting circuits, controlling the magnitude of current and voltage, voltage division, current division, and serving as heating elements. Resistors require bending structures during manufacturing.

[0003] A search revealed a patent document with publication number CN220774055U, which discloses a resistor bending structure. A positioning mechanism clamps and positions the two sides of a straight resistor. A bending plate drives a bending column to rotate, bending the straight resistor on the positioning mechanism into an L-shaped resistor. Compared to traditional shunt resistors, this eliminates the need for subsequent splicing and welding processes, avoiding the introduction of additional solder joints and solder, reducing material waste, while also ensuring good product performance, electrical properties, and guaranteeing product stability and reliability.

[0004] The aforementioned patent lacks a limiting mechanism for the ends of the straight-bar resistors during use, and manual placement can lead to errors, resulting in different bending positions each time. Therefore, we propose a resistor bending structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the lack of a limiting mechanism for the end of a straight-bar resistor, which leads to errors in manual placement and results in different bending positions each time. Therefore, this invention proposes a resistor bending structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A resistor bending structure, comprising:

[0008] A substrate, with a strip resistor placed on top of it;

[0009] A groove is provided on the substrate;

[0010] Two fixing rods are fixedly installed on the inner walls of both sides of the groove;

[0011] The sliding seat is slidably mounted on two fixed rods;

[0012] An electric actuator is fixedly installed on the top of the sliding seat;

[0013] The limiting block is slidably mounted on the top of the sliding seat. The output shaft of the electric push rod contacts one side of the limiting block. The electric push rod is used to adjust the position of the limiting block. The limiting block is used to limit one end of the straight strip resistor.

[0014] A bending assembly, located on a substrate, is used to bend straight-bar resistors.

[0015] Preferably, the bending assembly includes a central shaft fixedly mounted on the top of the substrate, and a rotating sleeve is movably sleeved on the central shaft.

[0016] Preferably, a connecting block is fixedly installed on the outer side of the rotating sleeve, and a bent column is fixedly installed on one end of the connecting block.

[0017] Preferably, a push rod is fixedly installed on the outer side of the rotating sleeve, and a limiting plate is fixedly installed on the top of the base plate.

[0018] Preferably, a rectangular groove is formed on the top of the substrate, and a clamping plate is slidably installed in the rectangular groove, with a straight-bar resistor located between the limiting plate and the clamping plate.

[0019] Preferably, a screw is rotatably installed in the rectangular groove, and the screw is threadedly connected to the clamping plate.

[0020] Preferably, one end of the screw extends to the outside of the substrate and is fixedly mounted with a rotating block.

[0021] Preferably, a through hole is provided on one inner wall of the rectangular groove, one end of the screw passes through the through hole, a bearing is fixedly installed in the through hole, and the outer side of the screw is fixedly connected to the inner ring of the bearing.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] This solution places a straight-bar resistor on the substrate through the gap between the limiting plate and the clamping plate, so that one end of the straight-bar resistor contacts the limiting block to limit the straight-bar resistor. Then, the rotating block is rotated, which drives the screw to rotate, causing the clamping plate to move and cooperate with the limiting plate to hold the straight-bar resistor. Then, the sliding seat is pushed to move, causing the limiting block to move away from the end of the straight-bar resistor. Finally, the rotating sleeve is put on the central shaft, and then the push rod is pushed. The push rod drives the rotating sleeve to rotate, and the rotating sleeve drives the connecting block and the bending column to rotate. The bending column cooperates with the central shaft to bend the straight-bar resistor.

[0024] This invention uses a limiting block to limit the end of a straight-bar resistor, ensuring a fixed bending position each time and preventing deviations. The position of the limiting block can be adjusted using an electric push rod to adapt to different bending requirements. Attached Figure Description

[0036] The limiting block 12 is slidably mounted on the top of the sliding seat 11. The output shaft of the electric push rod 13 contacts one side of the limiting block 12. The electric push rod 13 is used to adjust the position of the limiting block 12. The limiting block 12 is used to limit one end of the straight strip resistor 8.

[0037] A bending assembly, disposed on substrate 1, is used to bend the straight strip resistor 8.

[0041] In this embodiment, a rectangular groove 4 is provided on the top of the substrate 1, and a clamping plate 5 is slidably installed in the rectangular groove 4. The straight strip resistor 8 is located between the limiting plate 3 and the clamping plate 5.

[0042] In this embodiment, a screw 6 is rotatably installed in the rectangular groove 4, and the screw 6 is threadedly connected to the clamping plate 5.

[0043] In this embodiment, one end of the screw 6 extends to the outside of the substrate 1 and is fixedly mounted with a rotating block 7.

The outer side of the screw 6 is fixedly connected to the inner ring of the bearing.

[0045] In this embodiment, during use, the straight-bar resistor 8 is placed on the substrate 1 through the gap between the limiting plate 3 and the clamping plate 5, so that one end of the straight-bar resistor 8 contacts the limiting block 12 to limit the straight-bar resistor 8. Then, the rotating block 7 is rotated, which drives the screw 6 to rotate, so that the clamping plate 5 moves to cooperate with the limiting plate 3 to clamp the straight-bar resistor 8. Then, the sliding seat 11 is pushed to move, which drives the limiting block 12 to move away from the end of the straight-bar resistor 8. Finally, the rotating sleeve 14 is put on the central shaft 2, and then the push rod 17 is pushed. The push rod 17 drives the rotating sleeve 14 to rotate, and the rotating sleeve 14 drives the connecting block 15 and the bending column 16 to rotate. The bending column 16 cooperates with the central shaft 2 to bend the straight-bar resistor 8. Example 2

[0046] The difference between this embodiment and the first embodiment is that a push block 18 is fixedly installed on the sliding seat 11, which facilitates the movement of the sliding seat 11.
