Embodiment Construction

[0019] figure 1 , figure 2 as well as image 3 The embodiment of the contact mechanism of the AC contactor shown, it can be seen that the whole of the AC contactor includes three sets of contact mechanisms, and each set of contact mechanisms adopts an independently designed form. The three groups of contact mechanisms are independently isolated through three arc extinguishing chambers, which improves the breaking reliability of the arc, prevents the possibility of short circuit, improves the arc extinguishing performance, and improves the electrical life at the same time. Each set of contact mechanisms includes a housing 300 , a moving contact assembly 100 and two static contact assemblies 200 , and the two static contact assemblies 200 are respectively distributed on both sides of a moving contact assembly 100 .

[0020] Figure 4 to Figure 11 Shown is the specific structure of the static contact assembly 200, the static contact assembly 200 includes an arc guide 210, a w...

Abstract

The invention relates to a contact mechanism of an alternating-current contactor. The contact mechanism of the alternating-current contactor ensures the installing flatness of a static contact and accordingly solves the problem of high consistency of a three-phase contact. An original contact board function is replaced through combination of a wiring board and a conductive board, required flatness is easily ensured after machining due to the fact that the conductive board is short, accordingly the problems of high consistency and the flatness of the three-phase contact are solved, accordingly the synchronism of the three-phase contact is ensured, and the problem of power grid impact caused by instant current unbalance in the closing process of the contact mechanism is solved.

Description

technical field [0001] The invention relates to some mechanisms in the AC contactor, especially the contact mechanism of the moving and static contacts therein. Background technique [0002] In the original AC contactor, the static contact assembly in the contact mechanism includes a contact plate and a magnetic conduction ring. The contact plate is used to install the static contact and the terminal. It must be guaranteed that it has a certain length and is U-shaped. Type, due to the long horizontal length of the contact plate and the limitation of the forming process (using stamping), it is difficult to ensure its flatness on the mounting surface, resulting in the final installation of the static contact cannot be guaranteed to be flat, three sets of contacts corresponding to the three-phase connection The mechanism affects the synchronization of the three phases due to the different heights of the static contacts. Contents of the invention [0003] In order to overcome...
