Abstract

The invention provides an electronic control relay, relates to the technical field of relays, and solves the problems that: organic combination of a disassembly and assembly structure, a locking structure and a protection structure cannot be realized through structural improvement; automatic cleaning of a display screen cannot be realized during disassembly and assembly through the structural improvement; and auxiliary elastic locking cannot be realized for emergency. The electronic control relay comprises a fixed seat; a relay main body is installed on the fixed seat, and an auxiliary structure is further installed on the fixed seat. The seat body is of a concave structure and is matched with the head end of a fastening bolt; when the relay main body is clamped in a clamping seat, the seat body and the head end of the fastening bolt are in a clamping state, and the seat body forms a protection structure of the head end of the fastening bolt, so that collision protection of the head part of the fastening bolt can be realized.

Description

technical field [0001] The invention belongs to the technical field of relays, and more specifically relates to an electronic control relay. Background technique [0002] The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. [0003] For example, the application number: CN201010107535.0, the present invention relates to an electronic control relay, on the panel facing towards the housing side and extending straight back to form several fixed sides, each fixed side is provided with a card slot along its extending direction, There are several positioning slots on the card slot on the fixed side of the corresponding panel on the side of the base facing the shell; the four circuit boards of the power supply board, the power supply connection board, the setting board and the front ...
