Abstract

The invention relates to the technical field of the relay, more particularly to an improved moving-reed relay comprising a housing, an electromagnet assembly installed in the housing, a push member installed in the housing, and a contact assembly installed in the housing. The contact assembly consists of a static reed and a moving reed that are installed in the housing; and a static contact and amoving contact are arranged at the static reed and the moving reed respectively. One end of the push member is connected with the moving reed and the other end of the push member is connected with theelectromagnet assembly; and the electromagnet assembly drives the push member to move back and forth to drive the moving reed to move back and forth, so that connection or disconnected of the movingcontact and the static contact is realized by the moving reed moving back and forth. Besides, a sliding cavity for sliding of the push member is formed in the housing; an abutting protrusion abutted against the side of the push member is arranged on the wall of the sliding cavity; and the push member is provided with an oblique sliding surface abutted against the abutting protrusion. The improvedmoving-reed relay has advantages of simple and compact structure and low manufacturing cost; and problems that closing can not be realized and rebounding occurs are solved.

Description

Technical field [0001] The present invention relates to the technical field of relays, in particular to an improved dynamic reed relay. Background technique [0002] Reed relay is an electromechanical component, which is widely used in various power supply systems and power supply devices. The relay with permanent magnet can change the working state of the relay by pulse signal, which not only saves energy, but also works reliably. In the power line, when the relay is energized, because the current in the line is strong, a strong short-circuit current will be generated between the contacts at the moment of contact. The short-circuit current will produce a repulsive force opposite to the contact closing force, interfere with the closing force generated by the permanent magnet, and sometimes the contacts cannot be effectively closed, or even bounce back. As a result, strong arcs are generated, melting and burning the contacts, and damaging the relay. Affect the power supply. Sum...
