Abstract

The invention discloses an overload relay based on wireless connection and belongs to the technical field of overload relays. Firstly, a contact pin of a J27A-17ZK connector is inserted into a bonding pad of a first printed board assembly to be welded, and a contact pin of a J27A-17TJ connector is inserted into a bonding pad of a second printed board assembly and is welded. Then an electric conduction sealing gasket is arranged inside a groove of a shell body, a J599 connector is fixed on the shell body, the first printed board assembly is put into the shell body, a GK-8B relay on the first printed board assembly is put into the shell body inwards and is contacted with the shell body, a contact pin of the J599 connector is inserted into the bonding pad of the first printed board assembly and is welded, and the first printed board assembly and the shell body are fixed through screws on the back side of the first printed board assembly. The second printed board assembly is put into the shell body, the second printed board assembly and the shell body are fixed through screws, the electric induction sealing gasket is put into the groove of the shell body, is covered with a cover plate and is fixed through screws.

Description

technical field [0001] The invention belongs to the technical field of overload relays, in particular to an overload relay based on wireless connection. Background technique [0002] In the prior art, the Chinese patent with the notification number CN201479469U, the title of the invention is "An Electromagnetic Relay Wireless Harness Installation Structure", in which the electromagnetic relay (6) and the printed board (4) are respectively fixed on the metal fixing plate (7) On both sides of the electromagnetic relay (6), the pins of the electromagnetic relay (6) are welded on the printed board (4), the plug (5) is located on the printed board (4), and is connected to the metal fixed plate (7) through the connector, the plug ( 5) The solder pins on the plug (5) are also welded on the printed board (4), and the pin signals of the electromagnetic relay (6) correspond to the solder pin circuits on the plug (5). However, this structure cannot realize the wireless connection of e...
