Embodiment Construction

[0025] see Figure 1-4 As shown, the movable contact device for a single-throw double contactor includes a drive assembly 1.1 and a contact assembly 1.2; the contact assembly includes a linkage plate 1.3, and two sets of movable contact assemblies 1.4 are arranged at opposite ends of the linkage plate. In order to realize single-drive and double-moving contacts, the moving contacts are connected to the linkage rod. When the linkage rod moves, the moving contacts and the linkage plate work synchronously. The "bridge" contact structure formed by the linkage plate, the moving contacts on both sides The point components operate synchronously to ensure consistency; the linkage rod adopts metal parts to ensure the anti-vibration strength and impact resistance; and because the balance of the moving contacts is good, the release time of the product is fast and the synchronization of the release time is good.

Abstract

The invention relates to the field of contactor devices, in particular to a single-throw duplex contactor, a contactor moving contact device and a contactor ceramic cover assembly. A driving assemblyand a contact assembly are arranged; the contact assembly comprises a linkage plate, and two movable contact assemblies are oppositely arranged at the two ends of the linkage plate; due to the fact that the contact mode of the movable contact is adopted, the linkage design is adopted, the balance of the movable contact assembly is good, and the synchronism of attraction / release of the movable contact is greatly improved.

Description

technical field [0001] The invention relates to the field of contactor devices, in particular to a single throw double contactor, a movable contact device of the contactor and a ceramic cover assembly of the contactor. Background technique [0002] Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in electric power, power distribution and power consumption occasions. [0003] At present, the contactor generally has a magnetic circuit driving structure corresponding to a group of contact devices to form a circuit; when two circuits are required, two magnetic circuit driving structures and two sets of contact devices are generally required, so that the corresponding installation space also needs to be increased. , not suitable for small installation space. Contents of the invention [0004] The object of the present invention is to provide a single-throw double-connector contactor, a movable contact device of the contactor...
