A connector mateable with a mating connector along a first direction, wherein:
- the mating connector comprises a plurality of mating protrusions;
- each of the mating protrusions protrudes along the first direction;
- the mating protrusions include a first mating protrusion, a second mating protrusion, and a third mating protrusion;
- the connector comprises a terminal and a holding member which holds the terminal;
- the holding member is provided with a plurality of receiving portions;
- the receiving portions include a first receiving portion, a second receiving portion, and a third receiving portion;
- the first receiving portion is opened in each of the first direction and a second direction which is perpendicular to the first direction;
- when the connector is mated with the mating connector, the first receiving portion receives the first mating protrusion to regulate a movement of the first mating protrusion;
- the second receiving portion is opened in each of the first direction and a third direction;
- the third direction is perpendicular to the first direction and is different from the second direction;
- when the connector is mated with the mating connector, the second receiving portion receives the second mating protrusion to regulate a movement of the second mating protrusion;
- the second direction and the third direction are perpendicular to each other;
- the third receiving portion is opened in each of the first direction, the second direction and the third direction;
- when the holding member is seen along the first direction, the holding member has a rectangular shape which has longer sides and shorter sides;
- the first receiving portion is formed on one of the longer sides;
- the second receiving portion is formed on one of the shorter sides;
- the mating connector has mating receiving portions each of which is positioned between the mating protrusions;
- the connector has protrusions each of which is positioned between the receiving portions;
- when the connector is mated with the mating connector, the protrusions are received in the mating receiving portions, respectively;
- each of the protrusions has an end in the first direction;
- the holding member has a plurality of corner portions each of which couples one of the longer sides and one of the shorter sides with each other;
- at least one of the protrusions includes one of the corner portions and has a first part and a second part, the first part being positioned on one of the longer sides, and the second part being positioned on one of the shorter sides;
- the end of each of the protrusions is formed with a guide portion which intersects with the first direction;
- each of the protrusions consists of only a plate-like portion or only a combination of plate-like portions;
- the holding member has an outer circumference;
- the protrusions include two first protrusions, two second protrusions, and two third protrusions;
- the first protrusions are formed on the longer sides of the outer circumference, respectively;
- the second protrusions are formed on the shorter sides of the outer circumference, respectively;
- the third protrusions are formed on two of the corner portions, respectively;
- when the connector is mated with mating connector, the third receiving portion receives the third mating protrusion;
- the third receiving portion includes one of the corner portions;
- the third receiving portion has a first portion and a second portion;
- the first portion of the third receiving portion is positioned on one of the longer sides;
- and
- the second portion of the third receiving portion is positioned on one of the shorter sides.
