a wireless cable

Abstract

The invention provides a wireless line threading device, which comprises a first body used for being installed on a door leaf and a second body used for being installed on a door frame, wherein the first body and the second body are mutually opposite in installation position, the first body is provided with a contact head assembly, a spring assembly and a first circuit board, the first circuit board is provided with a magnetic reed switch, and the second body is provided with a corresponding contact disc assembly, a second circuit board and a magnet. The wireless line threading device furthercomprises a first IC unit and a second IC unit, wherein a signal input end of the first IC unit is coupled to the contact head assembly through the first circuit board and the magnetic reed switch, asignal input end of the second IC unit is coupled to the contact disc assembly through the second circuit board, the first IC unit and the second IC unit are coupled to an external power supply respectively through power supply wiring terminals and output signals through signal output ends. The wireless line threading device is simple in structure, rich in function and good in safety and has excellent practicability.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to a wireless wire passer for a door. Background technique [0002] In recent years, with the development of society and the gradual improvement of economic level, smart electric locks with better security and more functions are becoming more and more popular. In general, smart locks need to be connected to a power source. There are two specific implementation methods: one is to use a battery as a power source, but it has the disadvantages of short battery life, troublesome replacement, and inapplicability when a large current is required; It is directly connected to an external power supply. However, smart electric locks are generally installed on the door leaf. When the power line passes through the door leaf and the door frame, accidents such as being pinched or broken by the door leaf often occur, resulting in power failures. [0003] In order to solve the above ...

AI Technical Summary

Problems solved by technology

[0004] 1) Through the contact between the fixed striker and the contact plate, it is necessary to accurately adjust the relative position of the door leaf and the door frame during installation, otherwise it is easy to cause the striker and the contact plate to fail to contact, or the contact is too tight to affect the door opening and cause damage; 2) The function is simple , can only achieve a simple circuit connection function; 3) poor safety, when the striker and the contact plate are accidentally connected when the door is open (for example, when a child touches the striker and the contact plate with a conductive object), it is easy to cause contact errors. even dangerous
