The rear end portion of the contact holding portion 65b and the upper portion of the front end portion of the contact accommodating portion 65a communicate with each other. Plug connector positioning portions 66 are formed on both front left and right ends of the main body 61. The plug connector positioning portion 66 is formed in a rectangular parallelepiped shape protruding from the front left and right ends of the main body 61 in the left and right outward directions. The upper part of the plug connector positioning portion 66 is formed in a semicircular shape when viewed in the left-right direction. The apex of the plug connector positioning portion 66 projects slightly upward from the upper surface of the main body portion 61.

As shown in FIGS. 15 to 18, a protruding portion 67 that projects downward and extends in the front-rear direction is formed on the lower surface of the main body portion 61. As shown in FIG. 10, the protruding portion 67 is formed so as to have a length from the rear of the detachment prevention protrusion 46 to the front of the base portion 43 in the front-rear direction. A plurality of projecting portions 67 are formed on both the left and right sides of each contact accommodating portion 65a, and are formed at predetermined intervals in the left-right direction. The height of the protruding portion 67 is formed to be equal to or higher than the height of the base portion 43. The insertion portion 62 is formed in a rectangular parallelepiped shape, extends in the front-rear direction at the lower left and right end faces of the main body portion 61, and projects in the left-right outer direction. The movable housing 32 is installed on the fixed housing 31 by inserting the insertion portion 62 into the grooves 48 of the left and right walls 42 of the fixed housing 31. At that time, the protruding portion 44 of the fixed side housing 31 is located below the plug contact connecting portions 63 and 63 in the movable side housing 32. Further, the movable side housing 32 can be slidably moved (relatively moved) back and forth and left and right with respect to the fixed side housing 31.

The receptacle contact 33 is formed in a predetermined shape shown in FIG. 7 or the like by pressing (punching and bending) a thin flat plate of a conductive material such as metal. The receptacle contact 33 includes a press-fitting portion 71 (movable side contact first connecting portion, receiving leg) that is press-fitted and held by the contact holding portion 65b, and a pair of contacted portions 72 that hang down from the front end portion of the press-fitting portion 71 and extend vertically. , 72 (movable side contact first connection portion, receiving leg), a spring portion 73 (contact leg) extending rearward from the rear end of the press-fitting portion 71, and a rear tip portion of the spring portion 73. It has a sliding contact portion 74 (movable side contact second connecting portion, contact leg) that is slidably contacted with the sliding contact portion 53.

The press-fitting portion 71 is formed in a bifurcated shape from the rear side to the front side, and is divided into left and right parts. The press-fitting portion 71 is press-fitted into the contact holding portions 65b formed on the left and right sides of the groove-shaped plug contact connecting portion 63 so that the front is open. The pair of contacted portions 72, 72 hang down from the front tip portions of the left and right press-fitting portions 71, which are bifurcated. The contacted portions 72, 72 hang down from the front surface of the main body portion 61 of the movable side housing 32, and are exposed to the outside of the movable side housing 32. Between the pair of contacted portions 72, 72 is a receiving space in which the contact portion 22a of the plug contact 22 is received. Convex portions 75, 75 protruding inward in the left-right direction are formed at the lower tip portions of the contacted portions 72, 72. The upper side of the convex portion 75 is formed in an inclined shape that projects inward in the left-right direction toward the lower side. The left and right convex portions 75, 75 are formed so as to face each other, and the distance between them is such that the contact portion 22a of the plug contact 22 can be sandwiched between them. That is, the distance between the left and right convex portions 75, 75 (distance between the convex portions 75, 75) is smaller than the thickness of the contact portion 22a in the normal state (the state in which the contact portion 22a is not inserted). When the contact portion 22a is inserted, it is expanded by the contact portion 22a. When the plug housing 21 is fitted and connected to the movable housing in the vertical direction, the contact portion 22a of the plug contact 22 is press-fitted into the receiving space of the contacted portions 72 and 72, and the contacted portions 72 and 72 are pressed into the contact space. , It is slidably contacted and connected to the contact portion 22a of the plug contact 22 up and down.

As shown in FIG. 9, the spring portion 73 includes a first hanging portion 73a that hangs down from the press-fitting portion 71, and an intermediate portion 73b that extends from the lower tip portion of the first hanging portion 73a toward the rear upper side. It has a second hanging portion 73c extending diagonally downward from the rear end portion of the intermediate portion 73b. A sliding contact portion 74 is formed at the rear tip of the second hanging portion 73c. When the sliding contact portion 74 is brought into contact with the sliding contact portion 53 of the connecting piece 51 from above, the spring portion 73 is urged in the direction in which the sliding contact portion 74 is brought into contact with the sliding contact portion 53. The sliding contact portion 74 comes into contact with the contact surface 53a of the sliding contact portion 53. The receptacle contact 33 configured in this way is fixed to the movable housing 32 by holding the press-fitting portion 71 to hold the contact holding portion 65b of the movable housing 32. When the movable housing 32 is installed on the fixed housing 31, the spring portion 73 is elastically deformed (biased) so that the sliding contact portion 74 of the receptacle contact 33 and the contact surface 53a of the sliding contact portion 53 , Is maintained, and the sliding contact portion 74 faces the sliding contact portion 53 in the vertical direction and is slidably contacted in the front-rear and left-right directions.

The connection between the receptacle connector 3 and the plug connector 2 configured in this way will be described. First, the plug connector 2 is arranged so that the contact portion 22a of the plug contact 22 of the plug connector 2 is located above the plug contact connection portion 63 of the movable housing 32 of the receptacle connector 3. Then, the plug connector 2 is lowered to approach the receptacle connector 3. Then, the plug connector positioning portion 66 of the receptacle connector 3 is inserted into the positioning recess 26 of the plug connector 2.

At this time, since the positioning recess 26 is formed in a tapered shape in which the upper side is narrowed, the positions of the movable side housing 32 in the receptacle connector 3 with respect to the plug connector 2 are finely adjusted. At this time, the contact portion 22a of the plug contact 22 is inserted into the plug contact connection portion 63 of the movable housing 32 of the receptacle connector 3 from above. Since the upper left and right and the rear side of the plug contact connection portion 63 are formed in a tapered shape, when the plug contact 22 is inserted, the position of the movable housing 32 with respect to the plug connector 2 is slightly front, back, left and right. Adjustments are made.

When the position of the movable housing 32 with respect to the plug connector 2 is adjusted, the movable housing 32 slides back and forth and left and right with respect to the fixed housing 31. In that case, the sliding contact portion 74 of the receptacle contact 33 slides on the sliding contact portion 53 of the connecting piece 51 fixed to the fixed side housing 31, so that the electrical connection between the receptacle contact 33 and the connecting piece 51 is established. As a result, the electrical connection between the receptacle contact 33 and the wiring pattern of the second substrate 11 is maintained.

When the contact portion 22a of the plug contact 22 is inserted into the plug contact connection portion 63 in the vertical direction by a certain amount or more, the contact portion 22a comes into contact with the convex portion 75 of the contacted portion 72 of the receptacle contact 33. At this time, since the upper side of the convex portion 75 is formed in an inclined shape, the contact portion 22a is smoothly inserted between the convex portions 75 and 75. At that time, the contacted portion 72 expands, and the distance between the convex portions 75 and 75 expands in accordance with the contact portion 22a. The plug contact 22 comes into contact with the receptacle contact 33 so that the contact portion 22a is sandwiched between the left and right convex portions 75, 75, and is electrically connected to the receptacle contact 33. Since the distance between the left and right convex portions 75 and 75 of the receptacle contact 33 is smaller than the thickness of the contact portion 22a of the plug contact 22, when the contact portion 22a is inserted between the convex portions 75 and 75, A force acts in the direction in which the convex portions 75, 75 sandwich the plug contact 22, and the receptacle contact 33 and the plug contact 22 are suitably connected. In this way, the plug connector 2 and the receptacle connector 3 are electrically connected, and the first substrate 10 and the second substrate 11 are electrically connected.

The contact portion 22a of the plug contact 22 is connected to the receptacle contact 33 so as to be sandwiched in the left-right direction by the convex portion 75 of the contacted portion 72 of the receptacle contact 33. The contact portion 22a of the plug contact 22 has a predetermined width in the vertical direction. Therefore, even if the contact portion 22a moves relative to the plug contact connection portion 63 in the vertical direction, the connection between the contact portion 22a and the receptacle contact 33 is maintained. Therefore, when the plug connector 2 is connected to the receptacle connector 3, the plug contact 22 and the receptacle contact 33 can be connected even if the vertical positions of the plug connector 2 with respect to the receptacle connector 3 are slightly deviated. It can be connected to the receptacle connector 3.

The movable side housing 32 can move relative to the fixed side housing 31 in the front-rear and left-right directions. The connection piece 51 installed in the fixed side housing 31 is formed with a flat plate surface-shaped contact surface 53a extending in the front-rear and left-right directions, and even when the receptacle contact 33 moves in the front-back and left-right directions, the sliding contact portion of the receptacle contact 33 Since the 74 is in sliding contact, the connection between the receptacle contact 33 and the contact surface 53a is maintained even if the movable housing 32 moves back and forth and left and right. Therefore, when the plug connector 2 is connected to the receptacle connector 3, even if the position of the plug connector 2 is displaced in the front-rear direction or the left-right direction with respect to the receptacle connector 3, the deviation can be absorbed.

In the receptacle connector 3 formed in this way, when the movable housing 32 slides with respect to the fixed housing 31, the receptacle contact 33 fixed to the movable housing 32 is fixed to the fixed housing 31. Since the receptacle contact 33 is slidably contacted with the connecting piece 51 and maintained in a connected state, it is not necessary to bend the receptacle contact 33 vertically so as to be elastically deformable in the front-rear direction, and the size of the receptacle contact 33 in the vertical direction is large. Can be made smaller, and a low-profile receptacle connector 3 can be obtained.

Further, in this connector assembly 1, since the plug contact connection portion 63 is open not only upward but also forward, the plug contact 22 protruding in the front-rear direction can be inserted, and the plug connector 2 and the receptacle connector 3 can be inserted in the front-rear direction. Can be connected side by side. Therefore, the connector assembly 1 can be a low profile type.
