Contact part and switch apparatus

Abstract

The invention provides a contact part and a switch apparatus. The contact part includes: a first contact point, a second contact point and at least two flexible manipulators. The first contact point is arranged on a first flexible manipulator of the at least two flexible manipulators. The at least two flexible manipulators develop flexible deformation which make the first contact point and the second contact point to be in contact under the force of an external driver. The switch apparatus includes at least two drivers and the aforementioned contact part. The drivers are intended for driving the at least two flexible manipulators which are contained in the contact part. The technical solution herein can increase the distance between the two contact points.

Description

technical field [0001] The invention relates to the technical field of electrical and electronic engineering, in particular to a contact component and a switch device. Background technique [0002] At present, various electrical equipment are widely used in life and production. For example, televisions and electric vehicles in daily life, lathes and robot arms in industrial production, etc. Switchgear is an essential part of electrical equipment, and its consumption is very large. In order to ensure that the contacts of the switchgear have good electrical conductivity, especially for equipment such as contactors and relays used in industry, the contacts of the switchgear are generally made of silver alloy. In addition, the general switchgear includes at least two pairs of contacts. Point, because silver belongs to precious metal, its price is higher, thus the cost of switching device is higher. [0003] In order to reduce the cost of the switch device, the current solutio...

Problems solved by technology

[0004] Aiming at the method of reducing the cost of the switch device in the prior art, the deformation of an elastic arm drives the movement of the movable contact to realize the contact or separation of the movable contact and the static contact. Since the deformation of the elastic arm has a limit value, exceeding this limit After a certain value, the elastic arm will produce irreversible deformation or fatigue damage, resulting in failure or shortened life of the switch device. Therefore, the contact structure provided by the prior art has a small distance between the two contacts when it is not driven, and the two The small distance between two contacts will cause arcing when a large current passes through, so that the two contacts cannot be contacted or disconnected normally, so the switching device cannot be applied to a circuit with a large current
