Program electromagnetic switch lock

Abstract

The invention relates to a program electromagnetic switch lock which comprises a shell body and a mechanical program control lock body; the mechanical program control lock body is fixed in the shell body; the program electromagnetic switch lock further comprises an electric control lock body and a wiring terminal; the electric control lock body comprises a front iron core, a rear iron core, an iron core spring, a front baffle sheet, an iron square skeleton and a coil; the skeleton is fixed in the shell; the front baffle sheet is fixedly connected to one end of the skeleton; the rear iron core is fixedly connected in the skeleton; the front iron core is connected with the rear iron core through the iron core spring; the front iron core part stretches into the mechanical program control lock body; the coil is arranged on the peripheries of the rear iron core and the front iron core in the skeleton; the wiring terminal is arranged on the outer side face of the shell body; and the wiring terminal is in circuit connection with the electric control lock body. The program electromagnetic switch lock has the following advantages that a safety measure of preventing an error operation is added; meanwhile, the independent wiring terminal is provided for the introduction of a power supply to bring more convenience and reliability, and the connection with and control over a high voltage switch device are facilitated.

Description

technical field [0001] The invention belongs to the field of electrical machinery, in particular to a programmable electromagnetic knife switch lock. Background technique [0002] At present, the existing electromagnetic locks and program mechanical five-proof locks, electromagnetic locks use the power on and off of the control coil to attract the lock core, thereby realizing the locking function, while the program mechanical five-proof locks use the lock number and the slip of the key The rotation of the ring realizes the locking function. Although these locks can realize the locking function, they cannot realize some defects of preventing misoperation, and the current electromagnetic locks also have the problems of cumbersome wiring and unreliable wiring. There are certain hidden dangers in safe operation, and the reliability of locking cannot be guaranteed, nor can it cooperate with the use of other "five-defense" locks. Contents of the invention [0003] The purpose ...
