Connector

A connector which is mountable on an object in an up-down direction and mateable with a mating connector having a mating connection portion, wherein:

• the connector comprises a housing, a plurality of terminals and two additional members;
• the housing is formed with a receiving portion which receives the mating connector at least in part in a mated state;
• the housing holds the terminals and the additional members;
• the additional members are located at both ends of the housing, respectively, in a first direction perpendicular to the up-down direction;
• each of the additional members is provided with a connection mechanism;
• the connection mechanism is provided with a spring portion and a plate piece portion;
• the plate piece portion has an upper principal surface oriented upward in the up-down direction, a lower principal surface oriented downward in the up-down direction and an end face located between the upper principal surface and the lower principal surface in the up-down direction and oriented in a direction perpendicular to the up-down direction;
• the end face is provided with a connection portion which is connected to the mating connection portion when the connector and the mating connector are mated with each other;
• the connection portion is oriented inward of the connector in a second direction perpendicular to both of the up-down direction and the first direction and located in the receiving portion at least in part;
• in the connection mechanism, the spring portion supports the plate piece portion so as to allow the connection portion to move outward in the second direction when the mating connector is received in the receiving portion of the connector and inward in the second direction when the connection portion is pressed against the mating connection portion;
• each of the additional members has an upper wall portion;
• the spring portion extends from the upper wall portion;
• the plate piece portion is located downward of the upper wall portion;
• and
• the plate piece portion is hidden by the upper wall portion at least in part when viewed from above in the up-down direction.
