As shown in FIG. 6A, a part of the first extending part 43a or a part of the curved part 43c is outside the first connection part P1 between the first base part 41a and the first extending part 43a (that is, (The direction away from the inner housing 2). In other words, the first extending portion 43a has a portion P3 positioned forward or rearward with respect to the second connection portion P2 (the portion P3 is positioned at the same height as the second connection portion P2). Is the part that is.) That is, in the terminal 4 located on the front side, the part P3 is located in front of the second connection part P2, and in the terminal 4 located on the rear side, the part P3 is located behind the second connection part P2. ing. The portion P3 is located outward in the front-rear direction with respect to the first connection portion P1. That is, in the terminal 4 located on the front side, the part P3 is located in front of the first connection part P1, and in the terminal 4 located on the rear side, the part P3 is located behind the first connection part P1. doing. By doing in this way, for example, compared with the case where all of the curved portion 43c and the first extending portion 43a are disposed inside the first connecting portion P1, that is, the curved portion 43c and the first extending portion. The distance between the first extending portion 43a and the second extending portion 43b as compared with the case where all of 43a is arranged in a direction closer to the center of the inner housing 2 in the front-rear direction than the first connecting portion P1. L3 can be increased. As a result, the displacement allowed for the inner housing 2 can be increased in the front-rear direction. Further, the size of the elastic part 43 can be increased in the front-rear direction. That is, the terminal 4 and the connector 1 can be reduced in size while ensuring an allowable amount of displacement of the mating connector 9 when the mating connector 9 is inserted.

  In the present embodiment, the first extending portion 43a includes an inclined portion 43d extending obliquely upward and outward from the first base portion 41a, and an upward extending from the inclined portion 43d to the curved portion 43c. And a straight line portion 43e connected thereto. The first extending portion 43a is bent at a portion where the inclined portion 43d and the straight portion 43e are connected, and the straight portion 43e extends straight upward. That is, the straight line portion 43e is formed vertically. As a result, the width of the terminal 4 in the front-rear direction can be reduced, and as a result, the connector 1 can be reduced in size.

  As shown in FIG. 6A, at least a portion of the first engaging portion 41b is disposed outward in the front-rear direction (that is, in a direction away from the inner housing 2) relative to the first extending portion 43a. Good. In the present embodiment, the side surface S of the first engaging portion 41b is disposed outward from the first extending portion 43a (the two-dot chain line m in FIG. 6A indicates the position of the first extending portion 43a). Is shown.) By doing in this way, the clearance G1 (refer FIG. 5) is ensured between the front wall part 31F or the rear wall part 31B of the outer side housing 3, and the linear part 43e of the terminal 4, and the elastic part 43 is elastically made. It can be easily deformed.

  In addition, as shown in FIG. 6A, a first portion between the inner fixed portion 42 (more specifically, the second base portion 42a) and the elastic portion 43 (more specifically, the second extension portion 43b). 2 connection part P2 is from the 1st connection part P1 of the outer fixing | fixed part 41 (more specifically, 1st base 41a) and the elastic part 43 (more specifically, 1st extending | stretching part 43a). May also be located above. In the example shown in FIG. 6A, the second extending portion 43b is formed in a substantially L shape, and a first straight portion 43g extending in the Z-axis direction from the curved portion 43c, and the first straight portion A second linear portion 43f extending along the X-axis direction from the lower end of 43g (that is, the end portion on the Z2 direction side). The second base portion 42a extends from the second straight portion 43f along the X-axis direction. A space (see FIG. 5, connector housing portion 21) in which the mating connector 9 (see FIG. 7) is disposed is secured above the second straight line portion 43f and the second base portion 42a. In addition, a space E2 (see FIG. 5) in which the outer fixing portion 41 is disposed when the position of the inner housing 2 is displaced in the front-rear direction is secured below the second linear portion 43f. The second connection portion P2 is located at the end portion in the X-axis direction of the second straight portion 43f (in the example shown in FIG. 6A, the end portion on the X2 direction side). In other words, the second connection portion P2 is located at the end portion in the X-axis direction of the second base portion 42a (in the example shown in FIG. 6A, the end portion on the X1 direction side).

  As shown in FIG. 6A, by disposing the second connection portion P2 between the second base portion 42a and the elastic portion 43 above the first connection portion P1 between the first base portion 41a and the elastic portion 43, The first connection part P1 that functions as a fixed point of the elastic part 43 is shifted in the Z-axis direction with respect to the second connection part P2 that functions as a power point of the elastic part 43. For this reason, like the part shown with the dashed-two dotted line of FIG. 6A, the elastic part 43 is pushed outward (X1 direction in FIG. 6A), and the 2nd extending | stretching part 43b approaches the 1st extending | stretching part 43a. In this case, a moment acts, and the first extending portion 43a moves outward and in a diagonal direction (for example, the direction indicated by the arrow F in FIG. 6A). Thereby, the 2nd extending part 43b can move outward, and can elastically deform elastic part 43 greatly. That is, it is possible to increase the allowable amount of misalignment when the mating connector 9 is inserted.

  In addition, the shape of the terminal 4 which the connector 1 has is not necessarily limited to this. For example, as shown in FIG. 8, the first extending portion 43 a may extend in an oblique direction upward and outward (in a direction away from the inner housing 2) as a whole. The second extending portion 43b may extend obliquely upward toward the center of the inner housing 2 in the front-rear direction. Also by doing so, the relative size of the elastic portion 43 with respect to the entire terminal 4 can be increased, and the allowable amount of displacement when the mating connector 9 is inserted can be increased.

  8 has an outer fixing portion 141, an inner fixing portion 142, an elastic portion 143, a contact portion 144, and a substrate fixing portion 145, like the terminal 4 described above. ing. The outer fixing portion 141 has a first base portion 141a and a first engaging portion 141b, and the inner fixing portion 142 has a second base portion 142a and a second engaging portion 142b. . The elastic portion 143 has a first extending portion 143a, a second extending portion 143b, and a curved portion 143c. In the terminal 104, like the terminal 4 described above, a part of the first extending part 143a and a part of the curved part 143c are outside the first connection part P1 between the first base part 141a and the first extending part 143a. Is arranged. Further, the side surface S of the first engaging portion 141b is disposed outward from the first extending portion 143a. With these points, the relative size of the elastic portion 143 with respect to the entire terminal 104 can be increased in the front-rear direction, and the elastic portion 43 can be easily elastically deformed. That is, it is possible to increase the allowable amount of displacement when the mating connector 9 is inserted without increasing the size of the connector and the terminal 104.

  As shown in FIGS. 6A and 6B, the first base portion 41a and the second base portion 42a are extended in the front-rear direction (that is, the X-axis direction) and the vertical direction (that is, the Z-axis direction), thereby fixing the outer side. The portion where the portion 41 and the elastic portion 43 are connected and the portion where the inner fixing portion 42 and the elastic portion 43 are connected can be reinforced. Similarly to the terminal 4, also in the terminal 104 shown in FIG. 8, the first base portion 141a and the second base portion 142a are extended in the front-rear direction (that is, the X-axis direction) and the vertical direction (that is, the Z-axis direction). Thus, the strength of the portion where the outer fixing portion 41 and the elastic portion 43 are connected and the portion where the inner fixing portion 42 and the elastic portion 43 are connected can be increased. In the example of the terminal 104 illustrated in FIG. 8, the thickness of the second base portion 142 a is larger in the front-rear direction and the vertical direction than the thickness of the elastic portion 143. Thereby, the connection part P2 of the inner side fixing | fixed part 142 and the elastic part 143 can be reinforced.

  Next, the pair of support fittings 5 attached to the connector 1 will be described. As shown in FIG. 1, the pair of support fittings 5 may be attached to the left end and the right end of the outer housing 3 in order to support the inner housing 2 movably with respect to the outer housing 3. A support fitting receiving portion 33 for receiving the support fitting 5 may be formed on the left wall portion 31L and the right wall portion 31R of the outer housing 3. The support fitting housing part 33 may be formed as a groove, hole, or hole extending along the vertical direction.

  As shown in FIG. 4, the inner housing 2 may have overhang portions 25L and 25R that cover the upper portions of the left wall portion 31L and the right wall portion 31R of the outer housing 3, respectively. And the 1st latching convex part 26 which protrudes upwards may be formed in the upper surface of overhang | projection part 25L, 25R. In the present embodiment, the upper surfaces of the overhang portions 25L and 25R constitute the upper surface of the inner housing 2, but the positions of the overhang portions 25L and 25R in the inner housing 2 are not necessarily limited to this.

  The support metal fitting 5 may restrict the movement of the inner housing 2 exceeding a predetermined distance in the vertical direction, the front-rear direction, and the left-right direction. As shown in FIG. 1, the support metal 5 includes a main body 51, a base 52 that is a lower part of the main body 51 and is accommodated in the support metal fitting accommodating part 33 of the outer housing 3, and an upper part of the main body 51. It is possible to have restricting portions 53F and 53B that are connected to and restrict the movement of the inner housing 2. As shown in FIG. 4, the base portion 52 may be formed with an engaging portion 521 that is hooked on the edge (inner surface) of the support fitting housing portion 33. In the present embodiment, the engaging portion 521 is irregularities formed on the front and rear edges of the base portion 52, but the engaging portion 521 only needs to be caught by the outer housing 3, and the engaging portion 521 has a shape and a shape. The arrangement position is not necessarily limited to this.

  In the present embodiment, the restricting portions 53 </ b> F and 53 </ b> B of the support metal 5 extend from the upper portion of the main body 51 toward the center of the inner housing 2 in the left-right direction. The restricting portions 53F and 53B are located above the upper surface of the inner housing 2 (more specifically, the upper surfaces of the overhang portions 25L and 25R), and between the upper surface of the inner housing 2 and the restricting portions 53F and 53B. A gap is formed. Instead of this, the restricting portions 53 </ b> F and 53 </ b> B may be in contact with the upper surface of the inner housing 2. The support fitting 5 may be formed from a flat conductor material (metal plate). Further, the restriction portions 53F and 53B may be formed by being bent from the main body portion 51. In the present embodiment, the upper surface of the inner housing 2 (more specifically, the upper surfaces of the overhang portions 25L and 25R) is the upper surface of the outer housing 3 (more specifically, the upper surface and the right wall of the left wall portion 31L). The restriction portions 53F and 53B are also located above the upper surface of the outer housing 3.

  As shown in FIG. 2, the restricting portions 53 </ b> F and 53 </ b> B may be disposed on the front and rear sides of the first locking convex portion 26, respectively. The interval H1 in the front-rear direction of the restricting portions 53F and 53B is wider than the width H2 of the first locking convex portion 26. By doing in this way, the 1st latching convex part 26 of the inner side housing 2 which moved to the front-back direction contact | abuts the rear edge of the control part 53F, or the front edge of the control part 53B, and the front-back direction of the inner side housing 2 The movement in is regulated.

  Further, as shown in FIG. 4, the front wall portion 211F and the rear wall portion 211B of the inner housing 2 have second locking protrusions 27 that protrude further upward than the upper surfaces of the overhang portions 25L and 25R, respectively. May be. The restricting portions 53 </ b> F and 53 </ b> B of the support fitting 5 may be disposed at positions away from the second locking projection 27 in the left-right direction. As a result, the movement of the inner housing 2 in the left-right direction is restricted by the second locking projection 27 of the inner housing 2 that has moved in the left-right direction coming into contact with the edge of the tip of the restriction portions 53F, 53B. The Rukoto. Not limited to this, the left end of the left overhanging portion 25L or the right end of the right overhanging portion 25R may contact the main body 51 of the support bracket 5 or the movement of the inner housing 2 in the left-right direction may be restricted. .

  Moreover, as shown in FIG.1 and FIG.4, the inclined surfaces 261 and 271 may be formed in the 1st and 2nd latching convex parts 26 and 27, respectively. The inclined surfaces 261 and 271 are surfaces that extend obliquely downward toward the connector housing portion 21. As shown in FIG. 2, the width H <b> 3 in the left-right direction of the inclined surface 261 formed on the first locking projection 26 may be larger than the distance that the inner housing 2 can move in the left-right direction. Similarly, the width H4 in the front-rear direction of the inclined surface 271 formed on the second locking projection 27 may be larger than the distance that the inner housing 2 can move in the front-rear direction. In this way, for example, even when the relative positional deviation between the connector 1 and the mating connector 9 is equal to the upper limit of the movement allowable amount of the inner housing 2, the insertion of the mating connector 9 is reliably guided. The mating connector 9 can be mated with the connector 1.

  1 and 4 regulate the movement of the inner housing 2 exceeding a predetermined distance in the three directions of the vertical direction, the front-rear direction, and the left-right direction. The inner housing 2 may be fixed so that the inner housing 2 cannot move in one or more of the direction, the front-rear direction, and the left-right direction. For example, by setting the distance in the vertical direction between the restriction portions 53F and 53B and the upper surface of the inner housing 2 (more specifically, the upper surfaces of the overhang portions 25L and 25R) to be substantially zero, the inner housing 2 is moved in the vertical direction. Can be fixed. The inner housing 2 can be fixed in the front-rear direction by setting the distance in the front-rear direction between the restricting parts 53F, 53B and the first locking convex part 26 to be substantially zero. The inner housing 2 can be fixed in the left-right direction by setting the distance in the left-right direction between the restricting portions 53F, 53B and the second locking projection 27 to be substantially zero. In other words, the support metal fitting 5 may permit the movement of the inner housing 2 at a predetermined distance only in one or two of the vertical direction, the front-rear direction, and the left-right direction.

  The shape and arrangement of the support metal 5 included in the connector are not necessarily limited to this. For example, in the connector 100 shown in FIG. 9, the four support fittings 105 include two portions on the left side and the right side of the front wall portion 31F of the outer housing 3, and a rear wall portion (a wall portion on the opposite side to the front wall portion 31F). May be accommodated in four support fitting accommodating portions 33 formed at two locations on the left side and the right side. In this case, the support fitting 105 accommodated in the front wall portion 31 </ b> F may include a restriction portion 153 </ b> F extending rearward from the main body portion 151. The support fitting 105 accommodated in the rear wall portion may have a restriction portion 153B extending forward from the main body portion 151. Even in this way, when the inner housing 2 moves in the front-rear direction, the first locking projection 26 contacts the edge of the tip of the restricting portion 153F or the restricting portion 153B. Can be controlled. Further, when the inner housing 2 moves in the left-right direction, the second locking convex portion 27 abuts against the side edge of the restriction portions 153F, 153B, thereby restricting the movement of the inner housing 2 in the left-right direction. Can do.

  10, FIG. 11, FIG. 12A, and FIG. 12B are views showing a connector 200 that is still another modified example. In these drawings, the same reference numerals are given to the same portions as those of the connector 1 described so far. Below, it demonstrates centering on difference with the connector 1. FIG. Matters not described for the connector 200 are the same as those for the connector 1.

  The connector 200 has a terminal 204 (see FIG. 11). As illustrated in FIG. 12A, the terminal 204 includes an outer fixing portion 241, an inner fixing portion 242, an elastic portion 243, and a contact portion 244.

  As shown in FIG. 12A, the outer fixing portion 241 includes a first base portion 241a, a first engaging portion 241b, and a substrate fixing portion 241c. In the example of the connector 200, the board fixing portion 241c extends outward from the lower portion of the first base portion 241a in the front-rear direction and is positioned at the lower end of the terminal 204. That is, in the front terminal 204, the board fixing portion 241c extends forward from the lower portion of the first base portion 241a. In the rear terminal 204, the board fixing portion 241c extends rearward from the lower portion of the first base portion 241a. In the front terminal 204, the first engaging portion 241b extends upward from the front portion of the substrate fixing portion 241c. In the rear terminal 204, the first engaging portion 241b extends upward from the rear portion of the board fixing portion 241c. Therefore, the outer fixing portion 241 has a substantially U shape that opens upward when the outer fixing portion 241 is viewed in the left-right direction. On the edge of the first engagement portion 241b (the edge on the first base portion 241a side), a convex portion 241d hooked on the groove 31a formed in the lower portion (wall portions 31B and 31F) of the outer housing 3 (see FIG. 12B). ) Is formed.

  As shown in FIG. 12A, the inner fixing portion 242 has a second base portion 242a connected to the elastic portion 243, and a portion 242b bent with respect to the second base portion 242a (parts). 242b is referred to as a “folded portion”). In the terminal 204, unlike the terminal 4, the second base portion 242 a functions as an engaging portion that is hooked on the inner housing 2. Specifically, the second base portion 242a is formed with a convex portion 242c projecting in the plate thickness direction (left-right direction) of the second base portion 242a, and the convex portion 242c is a groove formed in the lower portion of the inner housing 2. It is caught by the inner surface of (terminal accommodating part 231). The contact portion 244 extends upward from the bent portion 242b.

  As shown in FIG. 12A, the elastic portion 243 includes a portion (first extending portion 243a) extending upward from the outer fixing portion 241 and a portion (second extension) extending upward from the inner fixing portion 242. The extending portion 243b) and a curved portion 243c that is curved in an arc shape between the first extending portion 243a and the second extending portion 243b. In the example of the terminal 204, the second extending portion 243b includes a second straight portion 243f (a portion extending in the front-rear direction toward the first extending portion 243a) extending from the inner fixed portion 242 in the front-rear direction. The first straight portion 243g is bent at the end of the second straight portion 243f and extends upward. A space (see FIG. 11, connector housing portion 21) in which the mating connector 9 (see FIG. 7) is arranged is secured above the second straight line portion 243 f. Further, a space E2 (see FIG. 11) in which the outer fixing portion 241 is disposed when the position of the inner housing 2 is displaced in the front-rear direction is secured below the second linear portion 243f.

  As illustrated in FIG. 12B, in the example of the terminal 204, unlike the example of the terminal 4, the first straight portion 243g extends obliquely toward the upper side and the outer side in the front-rear direction. That is, in the front terminal 204, the first straight portion 243g extends obliquely forward and upward from the second straight portion 243f, and in the rear terminal 204, the first straight portion 243g is rearward from the second straight portion 243f. And it extends obliquely upward. Accordingly, it is possible to suppress the bending portion 243c from entering the connector housing portion 21 when the position of the inner housing 2 is shifted in the front-rear direction. For example, when the position of the inner housing 2 is shifted forward, the first linear portion 243g can be prevented from inclining backward and the curved portion 243c entering the connector housing portion 21.

  As shown in FIG. 12B, the terminal 204 includes a first connecting portion P1 that is a connecting portion between the first extending portion 243a and the outer fixing portion 241, and a second extending portion 243b and the inner fixing portion 242. It has the 2nd connection part P2 which is a connection part. Similar to the example of the terminal 4, the second connection portion P2 is located above the first connection portion P1.

  As shown in FIG. 12B, the first extending portion 243a has a portion P3 that is positioned forward or rearward with respect to the second connection portion P2 (the portion P3 has the same height as the second connection portion P2). This is the part that is located.) That is, in the terminal 204 located on the front side, the portion P3 is located in front of the second connection portion P2, and in the terminal 204 located on the rear side, the portion P3 is located behind the second connection portion P2. ing. The portion P3 is located outward in the front-rear direction with respect to the first connection portion P1. That is, in the terminal 204 located on the front side, the portion P3 is located in front of the first connection portion P1, and in the terminal 204 located on the rear side, the portion P3 is located behind the first connection portion P1. doing. With this structure, the distance L3 between the first extending portion 243a and the second extending portion 243b is increased. As a result, the inner housing 2 can be greatly displaced in the front-rear direction.

  As shown in FIG. 12B, in the example of the terminal 204, the first extending portion 243a has an inclined portion 243d extending from the first connecting portion P1, and a linear portion 243e further extending from the inclined portion 243d. Yes. The inclined portion 243d extends obliquely outward and upward in the front-rear direction. That is, the inclined portion 243d of the terminal 204 positioned on the front side extends obliquely toward the front side and the upper side, and the inclined portion 243d of the terminal 204 positioned on the rear side is inclined toward the rear side and the upper side. It is growing. Due to the inclined portion 243d, the portion P3 is positioned outward in the front-rear direction with respect to the first connection portion P1. The first extending portion 243a is bent between the straight portion 243e and the inclined portion 243d, and the straight portion 243e extends upward (in the vertical direction) from the inclined portion 243d.

  As shown in FIG. 12B, in the example of the terminal 204, the upper end of the inclined portion 243d (the bent portion between the inclined portion 243d and the straight portion 243e) is below the second connection portion P2 (in other words, the second portion (Below the straight line portion 243f). That is, the height of the upper end of the inclined portion 243d is lower than the height of the second connection portion P2. With this structure, a gap G1 (see FIG. 11) is secured between the first extending portion 243a of the front terminal 204 and the front wall portion 31F of the outer housing 3, and the first extending portion of the rear terminal 204 is secured. A gap G1 (see FIG. 11) is secured between 243a and the rear wall portion 31B. Thus, the elastic portion 243 can be elastically deformed in the front-rear direction without being obstructed by the wall portions 31F and 31B. Note that the upper end of the inclined portion 243d may be positioned at the same height as the second connection portion P2. That is, the upper end of the inclined portion 243d may be located in front of or behind the second connection portion P2.

  Note that the shape of the terminal 204 is not limited to that shown in FIG. For example, instead of the inclined portion 243d, the terminal 204 may have a substantially L-shaped portion that extends upward from the first connection portion P1, and then bends and extends outward in the front-rear direction. That is, the terminal 204 located on the front side may have a substantially L-shaped portion that extends upward from the first connection portion P1, and then bends and extends forward. Further, the terminal 204 located on the rear side may have a substantially L-shaped portion that extends upward from the first connection portion P1, and then bends and extends rearward. The first extending portion 243a may extend upward from the substantially L-shaped portion.
