Problems solved by technology

[0012] The above-mentioned overall production process is relatively cumbersome, and the production efficiency of the high-voltage DC contactor is low; secondly, there are corresponding preset values ​​for the inflation pressure in the closed inner cavity of different high-voltage DC contactors, and the injection method through the exhaust pipe 5 It is easy to produce errors between the actual inflation pressure and the preset value, and its accuracy is difficult to guarantee

Embodiment Construction

[0038] refer to Figure 1 to Figure 5 The embodiments of the present invention will be further described.

[0039] Such as Figure 1 to Figure 5 Shown, a kind of production method of high-voltage DC contactor specifically comprises the following steps:

[0040] Step 1, assembling the filler: pre-install the static electrode ceramic shell parts, the bottom plate 4 and the moving magnetic core assembly in the sealed cavity 10 of a welding mold 9 according to the structure of the existing high-voltage DC contactor. The welding mold 9 includes The welding mold housing 91 and the welding mold cover 92 are composed, and the sealing cavity 10 is located in the welding mold housing 91. Specifically, by placing two left and right positioning molds 14 in the sealing cavity 10, the above positioning molds 14 abut, fix and seal Flange 3 and insulating porcelain shell 2, so that the entire contactor can be placed upright in the welding mold 9, between the sealing flange 3 and the insulat...

Abstract

The invention discloses a method of manufacturing for high-voltage direct current contactor. The method of manufacturing for high-voltage direct current contactor comprises following steps: step one, packaging packing; step two, vacuum pumping; step three, injecting inert gases; step four, heating and sealing-in in high temperature; step five, cooling and forming. The method of manufacturing disposably completes vacuum pumping, air charging and sealing-in through providing solder mask, technological process is greatly simplified, it is conducive to improving productivity, meanwhile higher accuracy grade of product can be kept.

Description

technical field [0001] The invention relates to a production method of an automatic control system component, more specifically, to a production method of a high-voltage direct current contactor. Background technique [0002] A DC contactor is a contactor used in a DC circuit, corresponding to an AC contactor, and generally has a main contact, an auxiliary contact and a coil contact. It is suitable for many new energy fields such as program-controlled power supply or uninterruptible power supply system, forklift, electric vehicle, mobile electric charging pile; when the contactor coil is energized, the coil current generates a magnetic field, so that the static iron core generates electromagnetic attraction to attract the moving iron core, And drive the contact action: the normally closed contact is disconnected, the normally open contact is closed, and the two are linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released ...
