Problems solved by technology

[0006] This type of interlock system 10-1 is long and difficult to install, especially when the first screw 10-13 is used to fix the interlock switch 10-10 on the bracket 10-12, and then the second screw 10-14 is used to fix the interlock switch 10-10. The bracket 10-12 is fixed in the housing 2-1 and finally connects the interlock switch 10-10 to the electronic control unit 20-1 by plugging the connector 10-16

Embodiment Construction

[0052] will now refer to Figure 5 to Figure 18 Embodiments of electrical devices according to the invention are described. In this example, the electrical device is an inverter for use in an electric or hybrid vehicle. However, the present invention is applicable to any type of electrical equipment, in particular any type of electrical equipment that operates at high voltage levels (eg in excess of 60 volts) and may pose a risk to the safety of the operator.

[0053] Figure 5 An example of an inverter 1-2 for an electric or hybrid vehicle is shown, such inverter 1-2 allowing control of the vehicle's electric motor (not shown). The inverter 1-2 includes a housing 2-2 in which a number of components as described below are mounted.

[0054] like Figure 6 to Figure 8 As shown, the inverter 1 - 2 includes an electronic control unit 20 - 2 , a bus bar 30 and pins 40 . The inverter 1-2 also includes a power supply module (not shown) that allows conversion of direct current re...

Abstract

The invention relates to an electrical device comprising a housing and an electronic control unit (20-2), the electronic control unit (20-2) comprising at least one safety switch (20C), the at least one safety switch is configured to turn off the electronic control unit (20-2) when the at least one safety switch (20C) is released and to turn on the electronic control unit (20-2) when the at least one safety switch (20C) is pressed. The electrical device further comprises a pin (40) comprising an elongated body having a proximal end and a distal end, the elongated body being configured such that in a position referred to as the closed position the distal end abuts an element of the housing (50) and the proximal end abuts at least one safety switch (20C) for turning on the electronic control unit (20-2).

Description

technical field [0001] The present invention relates to an electrical device in particular for an electric vehicle or a hybrid vehicle, and more particularly to an internal component (in particular a component at a high voltage level) when an operator attempts to access the electrical device ), electrical equipment that automatically shuts down in order to increase operator safety. [0002] The present invention aims to provide a simple, reliable and efficient mechanism based on a safety switch mechanism that can be activated or deactivated using a pin. Background technique [0003] In systems that include electrical circuits that transmit electrical energy, including modern vehicle propulsion systems, it is undesirable for operators to physically come into contact with components or systems (eg, inverters) that are at high voltage levels. [0004] exist figure 1 and figure 2 In the present solution shown, the inverter 1-1 comprises an electronic control unit 20-1 and a ...
