Problems solved by technology

[0002] As the "automatic switch" in the circuit, the relay is already one of the essential basic components in many electronic devices; most of the relays include drive components and contact components. In actual use, the drive components are used to drive the contact components to realize the contact components. The conduction or disconnection of the relay; most of the contact components of the existing relay are exposed. During the assembly process of the relay, other parts of the relay will touch the contact, resulting in damage to the contact; in addition, during the use of the relay, Other accessories of the relay will also interfere with the normal use of the contacts, which is not conducive to the improvement of the performance of the relay

Abstract

The invention relates to the technical field of relays, and particularly discloses a contact protection type relay, which comprises a base, a driving mechanism arranged on the base, a movable terminaland a static terminal. The base is provided with an accommodating groove. The static terminal is provided with a static contact which protrudes into the accommodating groove. The movable terminal isprovided with a movable contact which protrudes into the accommodating groove. The driving mechanism is used for driving the movable terminal to drive the movable contact to move back and forth so asto realize the on / off state of the movable contact with the static contact. According to the invention, the movable contact and the static contact are arranged in the accommodating groove. In this way, the movable contact and the static contact are protected by the side walls of the accommodating groove. During the assembling process of the relay, other accessories of the relay are prevented fromtouching the movable contact or the static contact, so that the service life of the contacts is prolonged. During the usage process of the relay, the interference caused by the normal use of other accessories of the relay to the contacts is avoided. The usage performance of the relay is improved.
