Abstract

The invention discloses a preparation technology of a sealing wire holder. The preparation technology is characterized by comprising the following steps: step one, cutting kovar alloy, and forming a shell through continuous die stamping; step two, uniformly mixing glass dust, paraffin wax and calcium oxide, and forming glass beads through fusion, die forming, de-waxing and cooling condensation respectively; step three, putting a guide pillar and the glass beads obtained in the second step into the shell obtained in the first step, carrying out sintering fixation to obtain samples; step four, carrying out electroplating treatment on the samples obtained in the third step; step five, welding resistors to the samples in the fourth step; and step six, carrying out silicon oil treatment on the samples in the fifth step to obtain finished products, wherein the grain diameter of the glass dust in the second step is 50-110 meshes, and the proportion of the glass dust, the paraffin wax to the calcium oxide is (15-20): 2: 1. The guide pillar, the glass beads and the shell are fixed in a die for sintering fixation, close integration is formed between the glass beads and the guide pillar and the shell by controlling temperature change, so that the preparation technology has good overall sealing property, and overall service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical components, more specifically, it relates to a preparation process of a sealed terminal block. Background technique [0002] The sealed terminal block is used to provide power for refrigerators or air conditioner compressors, and requires good airtightness. In order to better increase the airtightness of the sealed terminal block, glass columns are used to seal and fix the terminals installed in the sealed terminal block. Therefore, the quality of the glass column has high requirements. [0003] The Chinese patent with application publication number CN103441346A and application publication date of December 11, 2013 discloses a sealed terminal block for compressors, including a terminal base and three terminal posts. The terminal post installation holes are distributed in a triangle, and the terminal posts all pass through the terminal base, and are fixed in the terminal post installation holes...
