Automobile air-conditioning terminal series

In order to adapt to the development of new energy vehicles, KWT has developed different connectors suitable for the specifications and performance requirements of new energy vehicle air conditioner compressors in conjunction with new energy vehicle air conditioner compressor connectors, so that the air conditioner compressor power input motor can pass through.

KWTIn addition to meeting the performance requirements and technical standards, the new energy automobile air-conditioning compressor connector has a breakthrough in the structural strength of the product, breaking through the glass and ceramic co-sealing sintering process engineering, so that the entire connector can be sintered and packaged simultaneously in the same environment as the electrical conductivity The body pole and the jacket base body and the upper and lower layers of glass and ceramic are simultaneously sealed to form a combined whole. The upper and lower layers of glass and ceramic are co-sealed and sintered to meet the sealing and insulating layer of the connector. In addition to the normal glass and metal sintering and sealing process requirements, the entire sealing and sealing sintering process must also be suitable for glass and ceramic co-sealing sintering conditions. Utilizing the affinity of the microcrystalline structure of glass and ceramics, there is strong adhesion between glass and ceramics. The production sintering process must meet the toughness between glass and ceramics, and the co-sealing bonding strength can be guaranteed. Glass, ceramic and metal co-sealing sintering blank. In addition to meeting the performance requirements of the new energy automobile air-conditioning compressor connector, the mechanical strength and bonding strength of the product are also important standards to measure the performance of the connector. Due to various violent motions, collisions and other special conditions during the driving of the car, the ceramics of the air-conditioning compressor connector will fall off, causing the air-conditioning compressor to malfunction, and the connector must operate for a long time in harsh environments. If other sealants are used to seal ceramics, glass and metal together to form a combined whole, the connector will run for a long time in harsh environments, and the sealant will easily age in the refrigerant environment, causing the ceramic to fall off, and the insulation performance will decrease, which will seriously affect the air conditioning compressor The service life of the product, and the stability of the product performance cannot be guaranteed, which brings safety hazards to the air-conditioning compressor.

KWTIn order to meet the requirements of new energy automobile air-conditioning compressors to a greater extent, high-ampere, high-pressure-resistant connectors are produced. Under the condition that the position and space of the connector for the installation of the automobile air-conditioning compressor are not changed, the base body of the connector jacket adopts non-magnetic metal stainless steel and copper, and the electrical conductor pole adopts the co-sealing sintering process of copper, glass and ceramics to produce high ampere The high-voltage connector has successfully met the high-ampere power input penetration and performance requirements and standards of the new energy vehicle air-conditioning compressor.
