Connector

A connector connected to a counterpart connector, the connector comprising:

• a housing having a plurality of housing chambers into which a plurality of high-voltage terminals fixed to tip end portions of a plurality of high-voltage cables is inserted;
• and
• a connector position assurance that is provided in the housing so as to slide along an insertion/removal direction of the high-voltage terminal, and is slid from an unconnected position to a connection assurance position to ensure a position of the housing with respect to a counterpart housing when the housing is connected to the counterpart housing of the counterpart connector, wherein
• the housing includes
• at least one partition wall that partitions the plurality of housing chambers,
• a placing table provided to face the housing chamber and the partition wall from one side of a supporting direction orthogonal to the insertion/removal direction and an adjoining direction of the housing chamber, and on which the connector position assurance is slidably installed, and
• at least one insulating rib extending from all the partition walls in a pulling-out direction of the high-voltage terminal, increasing a clearance distance and a creepage distance between the high-voltage terminals housed in the adjacent housing chambers, and supporting the placing table protruding from the housing in the pulling-out direction or the connector position assurance protruding from the placing table in the pulling-out direction.
