And a receptacle connector 20 (an example of a second connector) to be attached. The plug connector 10 includes a housing 11 (an example of a first housing) and a plurality of conductive contacts 12 (an example of a first contact). The housing 11 includes a flat plate-shaped bottom wall portion 111 (an example of a first bottom wall portion) and a frame-shaped side wall portion 112 (first side wall portion) that stands on the bottom wall portion 111 along the outer periphery of the bottom wall portion 111. Section). The plurality of contacts 12 are arranged on a pair of wall portions 2121 of the side wall portion 212 that face each other. The receptacle connector 20 includes a housing 21 (an example of a second housing) and a plurality of conductive contacts 22 (an example of a second contact). The housing 21 includes a flat plate-shaped bottom wall portion 211 (an example of a second bottom wall portion) and a frame-shaped side wall portion 212 (second side wall portion) that stands on the bottom wall portion 211 along the outer periphery of the bottom wall portion 211. Section). The plurality of contacts 22 are arranged in the recess 27 formed by the side wall portion 212 and connected to the plurality of contacts 12. The corner portion of the side wall portion 112 has an inclined surface 1131 (an example of a first inclined surface) that is inclined toward the bottom wall portion 111 as it goes outward of the side wall portion 112. The corner portion of the side wall portion 212 projects in a direction away from the bottom wall portion 211, and when the plug connector 10 and the receptacle connector 20 are fitted to each other, a guide portion 214 that guides the guided portion 113 toward the bottom wall portion 211 is formed. Prepare Thereby, the guide function in the connector device 1 can be enhanced.

Further, the guide portion 214 has an inclined surface 25 (an example of a second inclined surface) that inclines toward the bottom wall portion 211 as it goes inward of the side wall portion 212. The inclined surface 25 allows the guided portion 113 to be more easily guided toward the bottom wall portion 211.

In addition, the guide portion 214 has a convex portion 26 that is continuous with the inclined surface 25 and that protrudes inward of the side wall portion 212. As a result, the inclined surface 25 can be formed as a convex curved surface in which the central portion in the width direction along the XY plane projects more than both end portions, and the position of the plug connector 10 and the receptacle connector 20 is appropriately corrected. be able to.

Further, the guided portion 113 has a concave portion 1132 which is continuous with the inclined surface 1131 and faces the convex portion 26 when the plug connector 10 and the receptacle connector 20 are in a fitted state. Accordingly, the concave portion 1132 of the guided portion 113 can be guided toward the bottom wall portion 211 while being in contact with the convex portion 26 of the guide portion 214, and the guide function of the connector device 1 can be further enhanced.

The inclined surface 1131 is a concave curved surface. As a result, the plug connector 10 can be guided into the receptacle connector 20 while being moved in the direction in which the positional deviation is reduced.
