In the connector 10 having the above configuration, a plurality of signal terminals 50 and a pair of power supply terminals 70 are bridged between the pair of side wall portions 30A and 30B of the fixed housing 30 and the movable housing 14. The plurality of signal terminals 50 are arranged in the front-rear direction (terminal arrangement direction X) orthogonal to the vertical direction (insertion / extraction direction Z) and the left-right direction (bridge direction Y), and are elastically deformed in the middle portion of the bridge direction Y. It has a possible first elastic portion 50B. The pair of power supply terminals 70 are arranged on both sides of the terminal arrangement direction X with respect to the plurality of signal terminals 50, and are bridged between the pair of side wall portions 30A and 30B. In these power supply terminals 70, the intermediate portion in the crossing direction Y is held at the end portion of the movable housing 14 in the terminal arrangement direction X, and is a portion located between the pair of side wall portions 30A and 30B and the movable housing 14. Each has a second elastic portion 70B that can be elastically deformed.

In this connector 10, the first elastic portion 50B of each signal terminal 50 and the pair of second elastic portions 70B of each power supply terminal 70 are elastically deformed, so that the movable housing 14 moves relative to the fixed housing 30. Permissible. As a result, it is possible to absorb the misalignment between the connector 10 and the mating connector 12.

Moreover, since the connector 10 has both the signal terminal 50 and the power supply terminal 70, the connector having the signal terminal and the connector having the power supply terminal are separately mounted on the circuit board as compared with the case where the connector has the signal terminal and the power supply terminal. The installation space of the connector 10 can be saved, and the work of assembling the connector 10 to the circuit board can be simplified.

Further, in this connector 10, since the plurality of signal terminals 50 and the pair of power supply terminals 70 are bridged between the common movable housing 14 and the fixed housing 30, the plurality of movable housings are arranged in the terminal arrangement direction X. The arrangement space of the movable housing 14 in the terminal arrangement direction X can be reduced as compared with the configuration provided side by side. Moreover, since each power supply terminal 70 is formed in a long shape having a longitudinal direction Y when viewed from the insertion / removal direction Z, the arrangement space of each power supply terminal 70 in the terminal arrangement direction X can be reduced. .. From the above, in the connector 10 according to the present embodiment, the overall configuration can be miniaturized in the terminal arrangement direction X.

Further, in the connector 10, the second contact portion 70A provided in the intermediate portion of the power supply terminal 70 in the extending direction is held at the end portion of the movable housing 14 in the terminal arrangement direction X. Since the second contact portion 70A is electrically contacted with the mating side power supply terminal provided on the mating side connector 12 and elastically deforms toward the plurality of signal terminals 50, the second contact portion 70A elastically deforms. It is not necessary to secure a space on the side opposite to the plurality of signal terminals 50 (outside the terminal arrangement direction X). Further, since the pair of second elastic portions 70B of the power supply terminal 70 extend from the second contact portion 70A to both sides in the overhead direction Y, the pair of second elastic portions 70B in the terminal arrangement direction X respectively. The placement space can be set small. Further, the pair of second connection portions 70C included in the power supply terminals 70 are located outside the terminal arrangement direction X (plural signal terminals 50) from the ends of the pair of second elastic portions 70B opposite to the second contact portion 70A. Is extended to the opposite side). Since the extending direction of the pair of second connecting portions 70C is set in this way, the pair of second connecting portions 70C is the end portion of the pair of second elastic portions 70B opposite to the second contact portion 70A. The second contact portion 70A and the pair of second elastic portions 70B can be arranged closer to the plurality of signal terminals 50 as compared with the configuration extending from each of the plurality of signal terminals 50 to the side. As a result, the movable housing 14 in which the second contact portion 70A is held at the end of the terminal arrangement direction X can be miniaturized in the terminal arrangement direction X. From the above, according to the present embodiment, the overall configuration of the connector 10 can be further miniaturized in the terminal arrangement direction X.

Further, in this connector 10, the pair of second elastic portions 70B of the power supply terminal 70 extend from the second contact portion 70A to both sides in the carrying direction Y (branch to both sides in the carrying direction Y). ing). Thereby, for example, as compared with the configuration in which the pair of second elastic portions 70B of the power supply terminal 70 are branched in the terminal arrangement direction X on one side of the carrying direction Y with respect to the second contact portion 70A, each second elastic portion 70 The portion 70B is easily elastically deformed.

Further, in the connector 10, a housing recess 22 opened toward the outside of the terminal arrangement direction X is formed at the end of the movable housing 14 in the terminal arrangement direction X. Most of the second contact portion 70A of the power supply terminal 70 is accommodated in the accommodating recess 22. This makes it easier to secure an arrangement space for the second contact portion 70A when the entire configuration of the connector 10 is miniaturized in the terminal arrangement direction X.

Moreover, in this connector 10, a pair of spring accommodating recesses 28 opened toward the outside of the terminal arrangement direction X and the outside of the extension direction Y are formed at the end of the movable housing 14 in the terminal arrangement direction X. .. A part of the pair of second elastic portions 70B included in the power supply terminal 70 is accommodated in the pair of spring accommodating recesses 28. As a result, when the entire configuration of the connector 10 is miniaturized in the terminal arrangement direction X, it becomes easy to secure a space for arranging the pair of second elastic portions 70B.

In other words, the accommodating recess 22 and the pair of spring accommodating recesses 28 are formed in the dead space that is the arrangement space of the movable housing 14, and the second contact portion 70A and the pair of second elastic portions 70B are formed in these recesses 22 and 28. Since a part of the connector 10 is accommodated, the entire configuration of the connector 10 can be further miniaturized in the terminal arrangement direction X.

Further, in the connector 10, the second contact portion 70A of the power supply terminal 70 is formed in a plate shape in which the plate thickness dimension along the terminal arrangement direction X is smaller than the width dimension along the spanning direction Y. Since a current larger than that of the signal terminal 50 flows through the power supply terminal 70 having the second contact portion 70A, it is required to secure a large cross-sectional area. In this respect, according to the present embodiment, the dimension of the second contact portion 70A in the terminal arrangement direction X can be set small while ensuring the cross-sectional area of the second contact portion 70A by the above width dimension. Therefore, according to the present embodiment, the overall configuration of the connector 10 can be further miniaturized in the terminal arrangement direction X.

Further, in the connector 10, the pair of second elastic portions 70B of the power supply terminal 70 has a second spring portion 70B1 that is bent so as to be convex in the removal direction (upward) of the movable housing 14. As a result, the pair of second elastic portions 70B can be easily elastically deformed while the size of the pair of second elastic portions 70B in the terminal arrangement direction X is set small.
