Referring to fig. 1 to 3, a UVW test plug of an automotive inverter includes a plug body 10, a driving device 20, a conductor 30, a floating engagement device 40, a driving force monitor 50, and a temperature sensor 60.

The plug body 10 serves as a structural body and serves as a structural support.

The driving device 20 is disposed on the plug main body 10, and the output end of the driving device 20 is connected with a conductor 30. The conductor 30 is used to clamp the UVW bus bar of the automotive inverter to be tested. The conductor 30 is clamped to the UVW bus while achieving circuit conduction.

The clamping action of the conductor 30 is driven by the driving device 20.

A temperature sensor 60 is provided on the conductor 30 for monitoring the temperature at the UVW bus of the automotive inverter when the test is performed.

In some preferred embodiments, the conductor 30 includes two clamping units 30a disposed side by side, and the clamping units 30a are linearly slidably connected to the plug body 10.

Referring to fig. 1, two clamping units 30a arranged side by side are moved toward each other by an external force, thereby realizing a clamping action. The clamping unit 30a is slidably connected to the plug body 10 in a straight line, so as to ensure that the clamping unit 30a can realize a clamping action of moving in opposite directions.

In a specific implementation, the clamping unit 30a and the plug main body 10 may be connected by a linear guide rail mechanism, and may be engaged by rolling engagement of rollers or other mechanisms capable of realizing linear relative movement.

In some preferred embodiments, the clamping monomer 30a is a copper bar. The copper bar made clamping unit 30a meets the electrical performance requirements for testing the automobile inverter.

In some preferred embodiments, the drive device 20 comprises one or more of a cylinder, an oil cylinder, an electric cylinder, and an electric pushrod.

The cylinder, the oil cylinder, the electric cylinder and the electric push rod can all output linear displacement, and on the basis, the action can be transmitted to the conductor 30 through the transmission mechanism to realize clamping. The motion may be directly transmitted to the conductor 30 without using a transmission mechanism.

If the conductor 30 is two clamping units 30a in linear sliding connection with the plug main body 10, the clamping units 30a can be pushed to move by linear displacement output by the driving device 20, so as to clamp the UVW bus bar of the automobile inverter.

In some preferred embodiments, the drive means 20 comprises a rotary cylinder 21 and a transmission 22, and the transmission 22 comprises a linear spring.

The rotary cylinder 21 outputs a linear displacement, and a transmission 22 is provided to be connected to an output end of the rotary cylinder 21. A linear spring is provided in the actuator 22 and is used to transfer the linear displacement of the output end of the rotary cylinder 21 to the conductor 30. The effect of the provision of the linear spring is that the force output by the rotary cylinder 21 is damped by the elasticity of the spring, avoiding the risk of damage caused by direct action on the conductor 30.

The floating mating device 40 provides the plug body 10 and is used for connecting the plug body 10 to the upper substrate of the UVW testing workstation. Reference is made to fig. 4.

Referring to fig. 1-3, the floating engagement means 40 is a means for free floating the test plug itself laterally with respect to the upper substrate of the UVW test workstation. Any mechanism capable of providing this function meets the requirements of this solution. For example, a columnar spring is provided laterally between the upper substrate and the plug main body 10, and a function of lateral floating is provided by the columnar spring; a gas spring is arranged between the upper substrate and the plug main body 10, and the function of transverse floating is provided by the gas pressure; a polymer material having elasticity, such as latex, is provided between the upper substrate and the plug body 10, and the elasticity of the polymer material is utilized to provide a lateral floating function; a magnet is provided between the upper substrate and the plug main body 10, and provides a lateral floating function by repulsive magnetic force.

In some preferred embodiments, the floating engagement means 40 comprises a spring, and the type of spring may be a cylindrical spring or a gas spring.

The driving device 20 is provided with a driving force monitor 50. By providing the driving force monitor 50, the driving pressure provided by the driving device 20 to the conductor 30 can be monitored, and whether the inverter UVW bus is sufficiently in contact with the conductor 30 can be judged by the pressure value. And the pressure value can also judge the influence of contact resistance between the UVW bus of the inverter and the conductor 30.

The working process of the UVW test plug of the automobile inverter during testing is as follows:

both the conductor 30 and the floating mating device 40 are in a free-centered state prior to the inverter UVW bus connection.

The UVW bus of the automotive inverter to be tested is inserted at the conductor 30 and clamping and circuit connection are achieved through the conductor 30. When the conductor 30 is composed of two clamping monomers 30a, the UVW bus bar to be tested is inserted into the gap formed by the two clamping monomers 30 a. The gap design formed between the two clamping monomers 30a accommodates the inverter UVW bus dimensional tolerance without the UVW bus and clamping monomers 30a rubbing.

The drive 20 drives the conductors 30 to clamp the inverter UVW bus. The floating engagement means 40 is adapted and engaged by its own floating movement to accurately clamp the UVW bus of the inverter with the conductor 30. When the conductor 30 is formed by two clamping monomers 30a, no matter which side of the clamping monomers 30a is attached to the inverter UVW bus, the floating matching device 40 can realize the closing of the clamping monomers 30a at both sides to the middle through floating, and attach to the inverter UVW bus under the condition of meeting the minimum contact resistance requirement. The inverter UVW bus and conductors 30 are in a relatively stationary state.

A UVW test workstation of an automobile inverter comprises an upper substrate 100, a jacking unit 200 and a carrier 300. The upper substrate 100 is connected with the UVW test plug of the automobile inverter. The carrier 300 is located below the upper substrate 100, and the jacking unit 200 is located below the carrier 300.

Referring to fig. 4, the upper substrate 100 is a suspension member provided at a work station. The carrier 300 is used for carrying an automobile inverter to be tested. The jacking unit 200 is used for lifting the carrier 300 and the automobile inverter together, so as to meet the test requirement. The UVW test plug of the automobile inverter is provided to the upper substrate 100 so as to facilitate the test by the workstation.

In some preferred embodiments, the jacking unit 200 is provided with a plug-in interface for connection to an automotive inverter. And the line connection of T+T-is realized through the plug-in interface.

In some preferred embodiments, the upper substrate 100 is provided thereon with a signal jack test unit 400 for connection to an automobile inverter. The signal circuit is connected through the signal connection socket.
