Safe on-off control assembly and PDU controller

Abstract

The invention discloses a safe on-off control assembly. The safe on-off control assembly comprises a shell, a conduction structure is arranged at the top of the shell, the conduction structure is connected with an overload protection structure, a winding wire turn is arranged at the bottom of the shell, a movable contact is arranged in the winding wire turn, and when the movable contact is in contact with the conduction structure, an energization loop is conducted; and when the movable contact is separated from the conduction structure, the power-on loop is disconnected. The invention furtherdiscloses a PDU controller which comprises a box body, and at least one safety on-off control assembly is arranged in the box body. The safe on-off control assembly provided by the invention has the functions of loop disconnection, connection and overload protection, only needs to be installed once, and is safe, reliable and convenient to use. According to the PDU controller provided by the invention, the overall space utilization rate is reduced, the boundary dimension of the PDU controller is reduced, the convenience of vehicle installation is improved, the installation connection among multiple parts is avoided, the assembly error is reduced, and the product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of controllers, in particular to a safety on-off control component and a PDU controller. Background technique [0002] The power system of electric vehicles needs to realize many related functions such as charge and discharge management, current and voltage detection for high and low voltage. In the current loop, the on-off switch of the loop is the most basic function to realize the control. [0003] At present, in the industry, the control of the energized circuit is realized through the use of two electrical components, relays and fuses. But there are the following problems: 1. There are too many and complex electrical components in the power supply circuit, and the space utilization rate is extremely low; 2. Each electrical component needs to be installed independently, and the corresponding installation structure and installation process should be added; 3. There is a need between the two electrical co...

Problems solved by technology

But there are the following problems: 1. There are too many and complex electrical components in the power supply circuit, and the space utilization rate is extremely low; 2. Each electrical component needs to be installed independently, and the corresponding installation structure and installation process should be added; 3. There is a need between the two electrical components Conductive busbar connection, there are processing and assembly errors, reducing the overall reliability of the product

For example: in the existing assembly of relays and fuses, it is necessary to separately fix the relay, the fuse base, and the fuse, and the connection between the three should also use fasteners. Correspondingly, the fixed point structure of the component shell also needs Increase, the assembly process also needs to increase the corresponding process, the installation structure and process are complicated
