Problems solved by technology

[0004] In view of the existing technology, the bridge contact structure includes at least two moving contacts and two static contacts. The contacts are generally made of silver alloy materials, and silver is a precious metal with a high price. Due to the large number of contacts , it needs to consume more silver alloy, resulting in a higher cost of the switching device using this bridge contact structure

Abstract

The invention provides a contact structure and a switch apparatus. The contact structure includes: a first contact point, a second contact point, a first contact manipulator and a second contact manipulator. The first contact manipulator includes at least two elastic sheets which are each in staggered arrangement, and one end of respective elastic sheets are in mutual fixed arrangement. The second contact point is arranged on the second contact manipulator. The first contact point is disposed on the first contact manipulator near the elastic sheet which is on one side of the second contact manipulator. The at least two elastic sheets of the first contact manipulator develop flexible deformation which make the first contact point and the second contact point to be in contact under the driving force. The switch apparatus includes at least one driver and the aforementioned contact structure. The technical solution can reduce the number of contact points of the contact structure.

Description

technical field [0001] The invention relates to the technical field of electronics and electricity, in particular to a contact structure and a switch device. Background technique [0002] Switching devices are essential electrical equipment for circuits. As a special type of switching devices, contactors and relays are widely used in power transmission, power distribution, and power consumption. When contactors or relays need to be used in high-current circuits, it is necessary to select corresponding high-current contactors or high-current relays to ensure that the contactors or relays can work normally under high currents and avoid heat damage caused by high currents. [0003] At present, in order to ensure that contactors or relays can withstand relatively large currents, high-current contactors or high-current relays generally adopt a bridge-type contact structure. The bridge-type contact structure includes a thick conductive bridge, and the two ends of the conductive br...
