Features of High Voltage Interlocking Connectors

High voltage interlock connectors are required for use with batteries, motors, electronic controls and high voltage systems. High voltage interlock connectors comply with LV215 or SR215 and USCAR industry standards. The most important performance of a high voltage interlock connector is to ensure the safety of the connector in use. For high-voltage interlock connectors, the most important thing is the whole high-voltage system, high-voltage system is generally designed to be determined by electrical signals. High-voltage interlocking connector characteristics:1. Sealing, board end and wire end in the separated state need to achieve IP67/IP68/IP69/IP69K waterproof grade, board end and wire end in the plug-in need to achieve waterproof IP67/IP68/IP69/IP69K waterproof grade. Some high voltage interlock connectors are generally installed under the car chassis when used in cars. Most of the high voltage interlock connectors are located in the chassis near the ground or near the tires. When the car passes through the puddle, the splashing water will impact the high voltage interlock connector. So high voltage interlock connector used in the car, generally will require the connector's waterproof grade to IP69K. 2. EMC / EMI: general equipment will have a lot of electronic components, voltage and high current will produce magnetic fields, so generally will require high voltage interlock connector requires the ability to anti-interference. High-voltage interlocking connector is through three ways to achieve the effect of shielding,, shielding layer connection. Plastic connectors will have a metal shell inside, wire shielding and connector shielding shell connected, will form a 360 ° shielding layer. Second, spring connection. High-voltage interlocking connector metal crimp ring with aluminum foil wrapped around the wire shield, which can also achieve the shielding effect. This way the connector is smaller and takes up less space then the connector contacts. Thirdly, the shield can be formed through a structure similar to a wave spring.3. High and low temperature resistance: -60°/+175°. High-voltage interlock connectors are more versatile and used in a wider range of environments, so the temperature range requirements are also higher.4. Board end connector (socket) anti-dislodgement: The board end of the high-voltage interlock connector, which is the end installed on the equipment, must have a structure to prevent dislodgement. Many high-voltage interlock connector board end of the internal are mainly copper row connection, this structure in the operation of the equipment, because of the vibration of the equipment and cause the connector to fall off. Then the high-voltage interlock connector in the design of the time must be used to bolt or nut fixed.5. High-voltage interlock connector in the connection state, the contact pressure of the contact is only related to the contact spring, the contact pressure is basically constant, to avoid contact wear and corrosion.6. Conductive contacts for the forked-ring structure, is a typical line contact, stable and reliable working condition, contact resistance is small, good heat dissipation properties. Connector without arc extinguishing device, and therefore must be in the absence of electricity to connect or separate the operation. 8. High-voltage interlocking Connector must be used in pairs. From the generality of the product and interchangeability to consider, each high-voltage connector structure is identical, with good interchangeability, there is no difference between before and after. In order to meet different operational requirements, can be any combination.
