AI Technical Summary

Problems solved by technology

Therefore, when the pair of second signal terminals 134 is in contact with the pair of first signal terminals 116, the force for rotating the lever 130 increases, and thus the operability of the lever 130 may be reduced.

Abstract

The present invention realtes to a power source circuit shutoff apparatus. In the power source circuit shutoff apparatus, with the lever rotated from a connector mating start position to a connector mating completion position, a pair of first signal terminals and a pair of second signal terminals are brought into on-state after a pair of first main terminals and a pair of second main terminals are brought into on-state. With the lever rotated from the connector mating completion position to the connector mating start position, a pair of first main terminals and a pair of second main terminal are brought into off-state after a pair of first signal terminals and a pair of second signal terminals are brought into off-state. The pair of first signal terminals and the pair of second signal terminals are each disposed along a straight line extending in a direction perpendicular to a rotational spindle direction of the lever.

Description

technical field [0001] The present invention relates to a power circuit disconnecting device which realizes connection and disconnection of a power circuit by fitting and disengaging a connector housing with a lever. Background technique [0002] Conventionally, in electric vehicles (EV) and hybrid electric vehicles (HEV), in order to ensure the safety of work such as maintenance of the electrical system, a power circuit disconnection device (power plug: service plug) (for example, refer to Patent Document 1 (Japanese Patent Laid-Open No. 2002-298704)). [0003] As a power circuit cut-off device, the applicant proposes Figure 1 ~ Figure 4 device shown. Specifically, as Figure 1 ~ Figure 3 As shown, the power circuit disconnecting device 100 includes: a first connector housing 110; a second connector housing 120 that fits and disengages from the first connector housing 110; and is disposed on the second connector housing 120, The lever 130 is rotatable, and a fitting for...
