Main power controller assembly

Abstract

The invention discloses a main power controller assembly, comprising a box body and a box cover, wherein a control circuit board is installed on the internal bottom plate of the box body and connected with an external wiring harness via an elbow insert; an insert mounting hole is formed in the side wall of the box body, the outlet end of an insert box penetrates through the insert mounting hole and is arranged horizontally towards the exterior of the box body, the inlet end of the insert box faces the lower part of the interior of the box body and is correspondingly connected with the control circuit board, and a building block type high-power fuse assembly, a power switch and the like can also be installed in the box body. The main power controller assembly is reasonable in structural design, compact and small in size, and can greatly reduce the occupied space over the existing main power control equipment; the components are installed regularly to facilitate installation and overhauling and effectively avoid potential safety hazard caused by disordered device installation and line arrangement.

Description

Technical field [0001] The invention relates to the technical field of electrical control, in particular to a main power supply controller assembly. Background technique [0002] The main power controller assembly is usually used in automatic machinery equipment such as vehicles and ships to realize functions such as connecting external buses, controlling external power supplies, and installing line protection and fuse components. Existing main power controllers are usually large in size, have many internally installed components, complex wiring, inconvenient installation and maintenance, and are prone to safety hazards. [0003] Generally, a control circuit board needs to be installed in the main power controller, and the control circuit board is connected to the external wiring harness. The existing connection method is through a wiring plug. One end of the plug is made into a pin structure adapted to the wiring harness, and the other end is connected to the wiring harness throug...

AI Technical Summary

Problems solved by technology

Existing main power controllers are usually large in size, with many devices installed inside and complex wiring, which is not easy to install and repair, and is prone to safety hazards

[0003] Usually, a control circuit board needs to be installed in the main power controller, and the control circuit board is connected to the external wiring harness. The existing connection method is through a wiring plug. The control circuit board realizes soft connection. This connection method also needs to solder the wires to a small circuit board to realize the connection between the circuit board and the plug. It not only takes up a large space, but also takes a lot of labor when installing and wiring. , time-consuming, and cause complex wiring in the control box, and it is extremely difficult to troubleshoot

[0004] The existing main power controller assembly is usually equipped with insurance components, which are generally integrated on the circuit board, and the total number of fuses is fixed. When customers need to install more fuses, the integral main gear The number of positions is often not enough, and other fuse holders need to be installed externally; when the customer needs less gears for insurance, the total number of overall gears is too much, and some gears are wasted, but the cost cannot be reduced. , occupying a larger space

And as long as there is a burnout of one insurance post, the circuit board needs to be replaced as a whole, resulting in time-consuming maintenance and replacement, high cost and short service life.
