  • Patent number: 10516228
    Abstract: A connector is mateable with a mating connector along an upper-lower direction (Z-direction). The connector comprises a housing and a terminal. The housing has a holding portion and an upstanding portion which are apart from each other in a width direction (Y-direction). The upstanding portion has a stop portion. The terminal has a held portion held by the holding portion and a spring portion extending from the held portion. The spring portion has a base portion and an upward extending portion extending upward from the base portion. The upward extending portion has a facing portion which faces the upstanding portion in the width direction. The facing portion has a stopped portion. Under a mated state where the connector and the mating connector are mated with each other, the stop portion is located above the stopped portion and faces the stopped portion in the upper-lower direction.
