Description

Hook structure and relay Technical Field The utility model relates to the technical field of relays, in particular to a hook structure and a relay. Background The relay is an automatic switching element for driving a mechanical component to move by using electromagnetic force, and generally comprises a base, a magnetic circuit part, a movable contact and a stationary contact, wherein the magnetic circuit part, the movable contact and the stationary contact are arranged on the base, and the magnetic circuit part generates electromagnetic force when being electrified so as to drive the movable contact and the stationary contact to be closed or opened. The magnetic circuit part comprises an armature and a yoke, the armature swings relative to the yoke and can reciprocate between a closing position and an opening position of the contact, so that the armature has a certain movable space relative to the yoke, and a hook is arranged on the base to preset the armature in order to ensure the movable degree of the armature relative to the yoke. When the hook in the prior art is installed on the base, the hook is only provided with a platy installation position connected with the base, and when the hook is installed on the base, the hook can be used for holding and installing less areas, namely the operability is lower, so that the installation is difficult. Disclosure of utility model To solve at least one of the problems in the prior art, according to one aspect of the present utility model, there is provided a hook structure comprising: The plug-in part comprises a first plug-in section, a connecting section and a second plug-in section which are sequentially connected, wherein the first plug-in section and the second plug-in section are respectively inserted into the base; And the abutting part is arranged at an included angle with the first inserting section and is used for abutting against the armature so as to apply pretightening force to the armature.
