Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay winding head removing mechanism. Background Technique

[0002] A relay is an electrical control device. When the change of the input quantity reaches the specified requirement, it is an electrical appliance that makes the controlled quantity have a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system and the controlled system. It is usually applied to an automatic control circuit. It is actually an "automatic switch" that uses a small current to control a large current operation. Therefore, it plays roles such as automatic adjustment, safety protection, and circuit conversion in the circuit. During the processing of the relay, if the head of the enameled wire is wound on other relay products, it will cause poor resistance of the relay and affect the normal use of the relay. For this reason, a relay winding head removing mechanism is needed to remove the head of the wire on the relay.

[0003] The existing patent (publication number: CN211654704U) discloses a relay winding head removing mechanism, including a base. Two symmetrically distributed fixing frames are fixedly connected above the base. A rotating seat is rotatably connected to the inner side of each fixing frame. By the way that the cutting knife is rotatably connected to the mounting frame, the angle of the cutting knife can be adjusted by sliding the sliding rod on the mounting plate, and the angle adjustment of the cutting knife is used to adapt to the removal of different enameled wire heads. During the implementation of this solution, it is found that the following problems exist in the prior art and have not been well solved: The above device adjusts the angle of the cutting knife through a locking nut to remove different enameled wire heads. However, when adjusting the locking nut, tools such as a screwdriver and a wrench are needed to fix the locking nut, which makes it inconvenient to adjust the angle of the cutting knife.
