Structure for detection of the number of items in an electrical connector

A different-item-number detection structure for detecting whether a combination of an electrical connector and a push-in jig is regular,

• wherein the connector includes a plurality of busbars and a housing including a plurality of busbar accommodation rooms configured to accommodate the plurality of busbars respectively,
• the housing includes a housing main body formed in a cylindrical shape and an insulation wall configured to partition an inside of the housing main body to insulate the busbars from each other, the busbar accommodation room being provided in a space that is partitioned by the insulation wall,
• the push-in jig includes a jig main body, a plurality of push-in portions provided to protrude from the jig main body for pushing in the busbars, and a detection portion provided in the jig main body and configured to detect whether or not the housing is regular,
• when the push-in jig is pushed toward the housing, in a case in which the detection portion is not in contact with the insulation wall, it is detected that the housing and the push-in jig form a regular combination, and
• when the push-in jig is pushed toward the housing, in a case in which the detection portion is in contact with the insulation wall, it is detected that the housing and the push-in jig form an irregular combination.
