[0002] A relay is an electrical control device. When the change in input quantity (excitation quantity) reaches the specified requirement, it causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between the control system (also called the input circuit) and the controlled system (also called the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

[0004] However, the device cannot adjust the position of the coil frame. The coil frame may need to be adjusted to a suitable position according to user needs during use. At the same time, the coil will rotate during use, which will cause errors and has limitations in use. Utility Model Content

[0005] Technical problem to be solved: The position of the coil frame cannot be adjusted, but the coil frame may need to be adjusted to a suitable position according to user needs during use. At the same time, the coil will rotate during use, which will cause errors and have limitations in use.

[0006] In view of the deficiencies of the prior art, the utility model provides a coil skeleton assembly for a relay, which solves the problems mentioned in the background technology.

[0007] Technical solution:

At the same time, after the coil is wound, there is excess coil that can be wound around the groove set on the coil frame. When the relay is working, the nut is tightened to prevent the wound coil from rotating, thereby preventing errors, which once again increases the practicality of the device.

The telescopic plate 10 is matched and connected with the second groove 16 set on the base 8. Since the limit block 14 is sleeved inside the rotating shaft 12, the rotating shaft 12 is rotatably connected to the limit block 14. Therefore, when the limit block 14 is not flush with the third groove 15, the limit block 14 is located inside the first groove 13. When the limit block 14 is flush with the third groove 15, the limit block 14 is taken out from the third groove 15, which fixes the telescopic plate 10 and the base 8 to a certain extent, further increasing the practicality of the device.

[0027] In some examples, a second groove 11 is provided on the top of the base 8, the telescopic plate 10 is matched and connected to the second groove 11, third grooves 15 are provided on both sides of the base 8, and connecting terminals 16 are provided on both sides of the base 8, which can fix the telescopic plate 10 and the base 8, and power is supplied by using the connecting terminals 16.
