High voltage interlocking connectors need to be used with batteries, motors, electronic controls and high voltage systems.High voltage interlocking connectors conform to LV215 or SR215 and USCAR industry standards.The most important performance of the high voltage interlocking connector is to ensure the safety of the connector in use.For high voltage interlocking connectors, the most important thing is the entire high voltage system, which is generally designed to be determined by electrical signals.Most of the manufacturers will design the high pressure inside the connector, but also some manufacturers put the high pressure interlock inside, and then design a high pressure interlock outside to ensure the stability of the high pressure interlock.If the high voltage interlock is discontinuous, the device will fail in service.

Features of high voltage interlocking connector:
1. Sealing, the board end and the wire end need to reach the waterproof level of IP67/IP68/IP69/IP69K in the state of separation, and the board end and the wire end need to reach the waterproof level of IP67/IP68/IP69/IP69K when inserted.Some high pressure interlocking connectors are generally installed under the chassis of the car when they are used in the car. Most of the high pressure interlocking connectors are located near the ground or near the tires.When the car passes through a puddle, the splashing water will hit the high voltage interlock connector.Therefore, when the high-pressure interlocking connector is used in the car, the waterproof level of the connector is generally required to reach IP69K.

2.EMC/EMI: general equipment will have a lot of electronic components, voltage and large current will produce magnetic field, so it is generally required that the high-voltage interlocking connector requires the ability of anti-interference.High voltage interlocking connectors are shielded in three ways. First, the shielding layer is connected.There will be a metal shell inside the plastic connector, and the wire shielding layer will be connected with the shielding shell of the connector, forming a 360° shielding layer.Second, spring connection.The metal crimping ring of the high voltage interlocking connector is wrapped around the wire shield layer with aluminum foil to achieve the shielding effect.As a result, the size of the connector is smaller and takes up less space, so the connector has more contacts.Third, a shielding layer can be formed through a structure similar to a wave-shaped spring.

3.High and low temperature resistance: -60°/+175°.High voltage interlocking connectors are widely used and used in a wide range of environments, so the temperature range is also relatively high.

4. Plate end connector (socket) anti-shedding: the plate end of the high voltage interlocking connector is the end installed on the equipment. It must have a structure to prevent shedding.Many high voltage interlocking connectors are mainly connected by copper bars at the board end. This structure will cause the connector to fall off due to the vibration of the equipment when the equipment is running.The high voltage interlocking connector must be fixed with bolts or nuts when it is designed.

5.The contact pressure of the high voltage interlocking connector is only related to the contact spring under the connection state, and the contact pressure of the contact is basically constant, so as to avoid the wear and electrical corrosion of the contact.

6.The conductive contact is a fork ring structure, which is a typical line contact mode. The working state is stable and reliable, the contact resistance is small, and the heat dissipation performance is good.

7.The connector is not equipped with an arc extinguisher, so the connection or separation operation must be carried out without power.

8.High voltage interlocking connectors must be used in pairs.Considering the versatility and interchangeability of the products, the structure of each high voltage connector is exactly the same, with good interchangeability, and there is no difference between before and after.In order to meet different operating requirements, can be arbitrarily combined.
