Abstract

The invention discloses a dual-electromagnetic relay which is characterized in that the dual-electromagnetic relay comprises a shell, a fixed device, electromagnetic components and contact components,the fixed device comprises a support rod and a support seat, the support seat is vertically fixed in the shell, the support rod is horizontally arranged and is fixed with a support seat by bolts, each of the electromagnetic components comprises an iron core, a coil, a coil frame and an energization circuit on the coil, the coil frame is fixed between the shell and the support seat, the iron corewhich is wrapped in the coil is arranged on the coil frame, each of the contact components comprises an armature and a moving contact, the armatures are arranged on an upper surface and a lower surface of one end of the support rod, the moving contacts are fixed to the other end of the support rod, and the contact components also comprise leading-out ends corresponding to the moving contacts and permanent magnets arranged in the supporting seat. According to the dual-electromagnetic relay, the attraction and separation of the contacts can be quickly achieved, and at the same time, the attraction and release of the contacts are effectively controlled through detecting the distances of the contacts.

Description

technical field [0001] The invention relates to the field of relays, in particular to a double electromagnetic relay. Background technique [0002] Electromagnetic relays are generally composed of electromagnets, armatures, spring sheets, contacts, etc., and their working circuits are composed of low-voltage / low-current control circuits and high-voltage / high-current working circuits. Electromagnetic relays can also realize remote control and automatic control. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The moving contact and the static contact (normally open contact) are sucked together. When the coil is powered off, the electromagnetic attraction will also disappear, and the armature will return to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) will be released...
