Embodiment Construction
[0025] refer to Figure 1A with Figure 1B An example of a housing of the disconnector 100 will be described. The switch 100 includes a housing that includes a first housing member 102 and a second housing member 104 . The second housing member 104 is movable relative to the first housing member 102 . refer to Figure 1A , the movement can be a rotation. refer to Figure 1B , the movement can be linear or translational. Alternatively, any other suitable movement of the second housing member relative to the first housing member may be employed in order to operate the disconnector 100, which operation will be described below.
[0026] Disconnector 100 also includes switch mechanism 112 (in dashed box Figure 2A with Figure 2B shown in ). In particular, the first housing member 102 is coupled to and surrounds the switch mechanism. The switch mechanism is movable between an open position and a closed position, wherein the circuit 118 connected to the switch mechanism (in ...

An isolating switch is provided. The isolating switch comprises a switching mechanism movable between an open position in which the circuit is open and a closed position in which the circuit is closedand a housing. The housing comprises: a first housing component coupled to and enclosing the switching mechanism, a second housing component coupled to the switching mechanism and movable with respect to the first housing component to move the switching mechanism between the open position and the closed position, at least one aperture, and test points electrically connected to the circuit. The second housing component is movable with respect to the first housing component between at least: a first relative position in which the switching mechanism is in the closed position and the at least one test point is not exposed, a second relative position in which the switching mechanism is in the open position and the at least one test point is not exposed, and a third relative position in whichthe switching mechanism is in either the closed or the open position and the at least one test point is exposed through the at least one aperture. The isolating switch can be for use with a high voltage circuit, such as a high voltage interlock circuit found in electric vehicles. A power train and an electric vehicle comprising the isolating switch are also provided.
Description
technical field [0001] The present invention relates to a disconnector with a test point, a powertrain for an electric vehicle including the disconnector and an electric vehicle including the disconnector. Background technique [0002] An electric vehicle, such as an electric vehicle, may include a high voltage circuit that connects high voltage components of the vehicle's electric powertrain to operate the electric vehicle (eg, a high voltage circuit that connects individual cells of the electric vehicle battery). However, in order to isolate components penetrated by such high voltage circuits for maintenance or testing, these high voltage circuits must be disconnected. For example, in order to service or test an electric vehicle battery, the electrical output of the battery must be isolated by disconnecting the high voltage circuit connecting the battery cells within the battery. [0003] Known products for isolating batteries (sometimes referred to as manual service swit...
