Problems solved by technology

Conventional electric coding locks are designed with two open normally open contacts or electrodes connected in series in the control circuit corresponding to the computer key. Even if the computer key is not used, the two normally open contacts can be connected by wire point or electrode conduction, unable to prevent vicious misoperation

Embodiment Construction

[0023] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0024] refer to figure 1 , the electric coded lock in one embodiment of the present invention includes a lock body 100, the lock body 100 includes an outer shell 110 and a rear cover 120, and an accommodating cavity is formed inside. The accommodating cavity is provided with a mechanical lock cylinder 400 that cooperates with the computer key, and a first pair of electrodes 300 controlled by the computer key. inside the lock. refer to image 3 , when the mechanical lock cylinder 400 is not unlocked, the connection line between the second pair of electrodes 200 and the connection line between the first pair of electrodes 300 are staggered by 90°. refer to Figure 4 When unlocking in normal operation, turn the first pair of electrodes 3...

Abstract

The invention relates to the field of microcomputer anti-misoperation equipment, in particular to an electric coder lock, and is intended to provide an electric coder lock high in safety and capable of preventing malicious misoperations such as anomalous wire connection. The electric coder lock comprises a lock body having a receiving cavity, a mechanical cylinder mating a computer key, a first pair of electrodes controlled to make and break via the computer key, and a second pair of electrodes arranged in the lock body and serially connectable to a control loop; the mechanical cylinder and the first pair of electrodes are arranged in the receiving cavity; the mechanical cylinder is connected with the first pair of electrodes through a connector; when the mechanical cylinder is in non-unlocking state, the first pair of electrodes and the second pair of electrodes are staggered; when the computer key is inserted into the receiving cavity and the mechanical cylinder is driven to rotate for unlocking, the mechanical cylinder drives the first pair of electrodes to rotate through the connector so that the second pair of electrodes and the first pair of electrodes are made.

Description

technical field [0001] The invention relates to the field of microcomputer error prevention devices, in particular to an electric coded lock. Background technique [0002] In the application of anti-misoperation in substations, electric coded locks are generally applied in series in the control loop of equipment such as switches or electric knife switches to prevent the loop from being turned on due to misoperation. Generally, when the control loop needs to be turned on, the computer key is inserted, and the control loop is turned on through the internal circuit of the computer key. Conventional electric coding locks are designed with two open normally open contacts or electrodes connected in series in the control circuit corresponding to the computer key. Even if the computer key is not used, the two normally open contacts can be connected by wire Point or electrode conduction, can not prevent vicious misoperation. Contents of the invention [0003] Based on this, aimin...
