Enhanced transmission mechanism of non-sealed direct-current contactor

Abstract

The invention provides an enhanced transmission mechanism of a non-sealed direct-current contactor. The mechanism comprises a shell, an end cover, a coil, a coil framework, an upper yoke, a lower yoke, a terminal, a movable iron core and a spring. A cavity is arranged in the shell, the end cover is arranged at an opening of the shell, the coil framework is placed in the cavity, the coil is wound on a side wall of the coil framework, and an installation through hole is arranged in the coil framework. The upper yoke is arranged on an upper side of the coil framework, a lower end of the upper yoke extends into the installation through hole of the coil framework, a two-stage stepped hole is arranged in the upper yoke, and a second-stage hole, located on a lower side, of the two-stage stepped hole is cooperated with a terminal. The lower yoke is arranged on the lower side of the coil framework, the upper end of the lower yoke extends into the installation through hole of the coil framework,a movable iron core extends into the installation through hole of the coil framework, and a spring abuts against the terminal and the movable iron core. The transmission mechanism is suitable for a non-sealed explosion-proof direct-current contactor, and firmness and mechanical strength of an overall structure can be ensured under the condition of ensuring an overall performance index of a product.

Description

technical field [0001] The invention relates to an enhanced transmission mechanism of a non-sealed DC contactor. Background technique [0002] In recent years, the country has vigorously advocated the development of new energy vehicles. Batteries, electronic controls, and corresponding supporting parts have developed rapidly, and the development of DC contactors has been particularly prominent. Currently, there are mainly two types of products on the market: Tyco epoxy seals and Panasonic ceramic seals. They are all sealed structures, but the sealing structure process is complex, there are many supporting production equipment, high production costs, and there are problems such as potential safety hazards of explosion; currently there is no DC contactor with a non-sealed structure, and there is also a lack of DC contactors with a non-sealed structure Dedicated transmission mechanism. Contents of the invention [0003] The technical problem to be solved by the present inven...
