Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a relay coil holder for high current and high load. Background Technology

[0002] As an electrical control device, relays are commonly used in automated control circuits. They control the switching of large currents by sensing current and play roles such as automatic adjustment, safety protection, and circuit switching in circuits. The core component of a relay is the coil winding. When making the coil winding, metal wire needs to be wound around a special coil frame.

[0003] Existing relay coil frames are mostly made of engineering plastics, which have good insulation properties. By designing pin slots on the coil frame, pins are inserted into the slots, and then wires are soldered to the pins to form a complete winding. However, for high-current, high-load relays, the heat generated by the large current in the circuit is also greater. If the existing pins are tightly inserted into the coil frame after installation, heat dissipation is prone to problems. If the insertion is loose, the solder joints are prone to fall off due to pin movement during use. Therefore, a high-current, high-load relay coil frame is specially provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-current, high-load relay coil holder, which solves the problem that high-current, high-load relays generate more heat due to the larger current in the circuit. In existing systems, if the pins are tightly connected to the coil holder after installation, heat dissipation is likely to be poor. If the connection is loose, the solder joints may fall off due to pin movement during use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-current, high-load relay coil frame, including a winding part and side stops integrally formed at both ends of the winding part, a set of the side stops integrally formed with a reinforcing mounting part, and a pin mechanism provided in the reinforcing mounting part, the pin mechanism including;

[0006] Built-in conductors are fixedly installed on both sides of the reinforced mounting part;

[0007] External pins are movably inserted into both sides of the reinforced mounting part and are fixedly welded to the internal conductor;

[0008] An expansion plastic pin is movably inserted into the reinforced mounting section, and its movement extends through the external pin.

[0009] Preferably, the reinforced mounting part has an assembly groove in the middle, and the built-in conductor is installed in the assembly groove.

[0010] Preferably, the built-in conductor includes a bonding and fixing part, and the two ends of the bonding and fixing part are respectively integrally formed with a welding end and a fixing end, and the welding end is fixedly welded to the external pin.

[0011] Preferably, the external pin includes an L-shaped pin, the bottom end of which is integrally formed with a hollow metal plate, and the other end of which is integrally formed with a welding foot, and the welding foot is fixedly welded to the welding end.

[0012] Preferably, a through-shaped wiring groove is provided on the inner wall of one end of the assembly groove, and a limiting block is integrally formed on the inner wall of the assembly groove. The fitting and fixing part is movably engaged with the inner wall of the assembly groove through the limiting block.

[0013] Preferably, the outer wall of the fixed end is provided with a welding pressure plate, which is fixed to the side wall of the assembly groove by bolts.

[0014] Preferably, both ends of the reinforced mounting part are provided with pin slots, the hollow metal plate is movably inserted into the pin slots, and heat dissipation protrusions are provided on both outer walls of the hollow metal plate. The hollow metal plate maintains a gap with the inner wall of the pin slot through the heat dissipation protrusions.

[0015] Preferably, a connecting groove is provided between the pin slot and the assembly slot, and the welding pin passes through the connecting groove.

[0016] This utility model discloses a high-current, high-load relay coil holder, which has the following advantages: By designing an internal conductor and external pins, the internal conductor is fixed in the assembly slot, while the external pins are fixed by expansion plastic pins, making the entire pin mechanism immobile. At the same time, the external pins are designed with hollow metal plates, and the two sides of the hollow metal plate are suspended from the pin slot by heat dissipation protrusions. This ensures a secure fixation, prevents the entire pin mechanism from moving during use, and effectively solves the heat dissipation problem. Attached Figure Description
