It has a connecting linear portion 43e. 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 linear 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 miniaturized.

Further, as shown in FIG. 6A, at least a part of the first engaging portion 41b is arranged outside the first extending portion 43a in the front-rear direction (that is, in the direction away from the inner housing 2). good. In the present embodiment, the side surface S of the first engaging portion 41b is arranged outside the first extending portion 43a (in FIG. 6A, the two-dot chain line m indicates the position of the first extending portion 43a). shows.). By doing so, a gap G1 (see FIG. 5) is secured between the front wall portion 31F or the rear wall portion 31B of the outer housing 3 and the linear portion 43e of the terminal 4, and the elastic portion 43 is elastically moved. It can be easily deformed.

Further, as shown in FIG. 6A , the inner fixed portion 42 (more specifically, the second base portion 42a) and the elastic portion 43 (more specifically, the second extending portion 43b) are positioned between the second The second connecting portion P2 is formed from the first connecting portion P1 between the outer fixing portion 41 (more specifically, the first base portion 41a) and the elastic portion 43 (more specifically, the first extending portion 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 includes a first linear portion 43g extending from the curved portion 43c in the Z-axis direction, and the first linear portion 43g. and a second linear portion 43f extending along the X-axis direction from the lower end of 43g (that is, the end on the Z2 direction side). The second base portion 42a extends from the second linear portion 43f along the X-axis direction. A space (see FIG. 5, connector accommodating portion 21) in which the mating connector 9 (see FIG. 7) is arranged is secured above the second straight portion 43f and the second base portion 42a. A space E2 (see FIG. 5) is secured below the second linear portion 43f in which the outer fixing portion 41 is arranged when the position of the inner housing 2 is displaced in the front-rear direction. The second connecting portion P2 is located at the end of the second linear portion 43f in the X-axis direction (the end in the X2 direction in the example shown in FIG. 6A). In other words, the second connecting portion P2 is located at the end of the second base portion 42a in the X-axis direction (the end in the X1 direction in the example shown in FIG. 6A).

As shown in FIG. 6A, by arranging the second connecting portion P2 between the second base portion 42a and the elastic portion 43 above the first connecting portion P1 between the first base portion 41a and the elastic portion 43, The first connecting portion P1 functioning as a fixing point of the elastic portion 43 is shifted in the Z-axis direction with respect to the second connecting portion P2 functioning as a force point of the elastic portion 43 . Therefore, as indicated by the two-dot chain line in FIG. 6A, the elastic portion 43 is pushed outward (X1 direction in FIG. 6A), and the second extending portion 43b approaches the first extending portion 43a. In this case, a moment acts and the first extension 43a moves outward and downward in an oblique direction (for example, the direction indicated by arrow F in FIG. 6A). As a result, the second extending portion 43b can move outward, and the elastic portion 43 can be elastically deformed to a large extent. That is, it is possible to increase the allowable amount of positional deviation 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 43a as a whole may extend obliquely upward and outward (direction away from the inner housing 2). Also, the second extending portion 43b may extend obliquely upward toward the center of the inner housing 2 in the front-rear direction. By doing so, it is also possible to increase the relative size of the elastic portion 43 with respect to the entire terminal 4, and to increase the allowable amount of positional deviation when the mating connector 9 is inserted.

The terminal 104 shown in FIG. 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, similarly to 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, as in the terminal 4 described above, a portion of the first extending portion 143a and a portion of the curved portion 143c are located outside the first connecting portion P1 between the first base portion 141a and the first extending portion 143a. are placed in In addition, the side surface S of the first engaging portion 141b is arranged outside the first extending portion 143a. Due to 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 elastically deformed easily. That is, it is possible to increase the allowable amount of misalignment when the mating connector 9 is inserted without increasing the size of the connector and the terminals 104 .

As shown in FIGS. 6A and 6B, by extending the first base portion 41a and the second base portion 42a in the front-rear direction (that is, the X-axis direction) and the vertical direction (that is, the Z-axis direction), the outer fixation A portion where the portion 41 and the elastic portion 43 are connected and a portion where the inner fixed portion 42 and the elastic portion 43 are connected can be reinforced. Similarly to the terminal 4, in the terminal 104 shown in FIG. 8, the first base portion 141a and the second base portion 142a can be 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 fixed portion 41 and the elastic portion 43 are connected and the portion where the inner fixed portion 42 and the elastic portion 43 are connected can be increased. In the example of the terminal 104 shown in FIG. 8, the thickness of the second base portion 142a is larger than the thickness of the elastic portion 143 in the front-rear direction and the vertical direction. This makes it possible to reinforce the connecting portion P2 between the inner fixing portion 142 and the elastic portion 143 .

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

Further, as shown in FIG. 4, the inner housing 2 may have projecting 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. A first engaging projection 26 projecting upward may be formed on the upper surfaces of the projecting portions 25L and 25R. In this embodiment, the upper surfaces of the projecting portions 25L and 25R form the upper surface of the inner housing 2, but the positions of the projecting portions 25L and 25R on the inner housing 2 are not necessarily limited to this.

The support fitting 5 may restrict movement of the inner housing 2 beyond a predetermined distance in the vertical direction, the front-back direction, and the left-right direction. As shown in FIG. 1, the support metal fitting 5 includes a main body portion 51, a base portion 52 which is a lower portion of the main body portion 51 and is accommodated in the support metal fitting accommodation portion 33 of the outer housing 3, and an upper portion of the main body portion 51. and restricting portions 53F and 53B for restricting movement of the inner housing 2. As shown in FIG. Further, as shown in FIG. 4 , the base portion 52 may be formed with an engaging portion 521 that is hooked to the edge (inner surface) of the support fitting housing portion 33 . In the present embodiment, the engaging portion 521 is unevenness formed on the front and rear edges of the base portion 52. However, the engaging portion 521 may be anything as long as it is hooked on the outer housing 3. The arrangement position is not necessarily limited to this.

In this embodiment, the restricting portions 53F and 53B of the support fitting 5 extend from the upper portion of the main body portion 51 toward the center of the inner housing 2 in the left-right direction. The restricting portions 53F and 53B are positioned above the upper surface of the inner housing 2 (more specifically, the upper surfaces of the overhanging portions 25L and 25R), and between the upper surface of the inner housing 2 and the restricting portions 53F and 53B. gap is formed. Alternatively, the restricting portions 53</b>F, 53</b>B may be in contact with the upper surface of the inner housing 2 . Note that the support fitting 5 may be formed from a flat conductor material (metal plate). Moreover, the restricting portions 53</b>F and 53</b>B may be formed by bending the body portion 51 . Further, in the present embodiment, the upper surface of the inner housing 2 (more specifically, the upper surface of the protruding 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). 31R), and the restricting portions 53F and 53B are also positioned above the upper surface of the outer housing 3. As shown in FIG.

As shown in FIG. 2, the restricting portions 53F and 53B may be arranged in front of and behind the first locking protrusion 26, respectively. A space H1 between the restricting portions 53F and 53B in the front-rear direction is wider than the width H2 of the first locking projection 26. As shown in FIG. By doing so, the first locking protrusion 26 of the inner housing 2 that has moved in the front-rear direction comes into contact with the rear edge of the restricting portion 53F or the front edge of the restricting portion 53B. movement is restricted.

In addition, as shown in FIG. 4, the front wall portion 211F and the rear wall portion 211B of the inner housing 2 each have a second locking projection 27 that projects further upward than the upper surfaces of the projecting portions 25L and 25R. may The restricting portions 53</b>F, 53</b>B of the support fitting 5 may be arranged at positions separated from the second locking protrusion 27 in the left-right direction. As a result, the second locking projection 27 of the inner housing 2 that has moved in the left-right direction comes into contact with the edge of the tip of the restricting portions 53F and 53B, thereby restricting the movement of the inner housing 2 in the left-right direction. The Rukoto. The movement of the inner housing 2 in the left-right direction may be restricted when the left end of the left overhanging portion 25L or the right end of the right overhanging portion 25R hits the main body portion 51 of the support metal fitting 5. .

Also, as shown in FIGS. 1 and 4, inclined surfaces 261 and 271 may be formed on the first and second locking protrusions 26 and 27, respectively. The inclined surfaces 261 and 271 are surfaces extending obliquely downward toward the connector accommodating portion 21 . As shown in FIG. 2, the width H3 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. By doing so, for example, even if the amount of relative positional deviation between the connector 1 and the mating connector 9 is equal to the upper limit of the movement allowance 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 restricts movement of the inner housing 2 beyond a predetermined distance in three directions, i.e., the vertical direction, the front-rear direction, and the horizontal direction. The inner housing 2 may be fixed such that the inner housing 2 cannot move in one or more of the directional, front-to-rear, and left-to-right directions. For example, by setting the vertical distance between the restricting portions 53F, 53B and the upper surface of the inner housing 2 (more specifically, the upper surface of the overhanging portions 25L, 25R) to substantially zero, the inner housing 2 can be moved vertically. can be fixed. The inner housing 2 can be fixed in the front-rear direction by making the distance in the front-rear direction between the restricting portions 53F, 53B and the first locking protrusion 26 substantially zero. By setting the distance between the restricting portions 53F, 53B and the second locking protrusion 27 to substantially zero in the horizontal direction, the inner housing 2 can be fixed in the horizontal direction. In other words, the support bracket 5 may allow the inner housing 2 to move a predetermined distance only in one or two of the up-down direction, front-rear direction, and left-right direction.

The shape and arrangement of the support bracket 5 of the connector are not necessarily limited to this. For example, in the connector 100 shown in FIG. 9, the four support fittings 105 are mounted on the front wall 31F of the outer housing 3 at two locations, one on the left and one on the right, and the rear wall (the wall on the side opposite to the front wall 31F). may be accommodated in four support metal fitting accommodating portions 33 formed at two locations on the left side and right side of the . In this case, the support fitting 105 housed in the front wall portion 31F may have a restriction portion 153F extending rearward from the body portion 151. As shown in FIG. The support fitting 105 housed in the rear wall portion may have a restricting portion 153B extending forward from the body portion 151 . With this configuration as well, when the inner housing 2 moves in the front-rear direction, the first locking protrusion 26 abuts the edge of the tip of the restricting portion 153F or the restricting portion 153B. movement can be regulated. Furthermore, when the inner housing 2 moves in the left-right direction, the second locking protrusions 27 abut against the side edges of the restricting portions 153F and 153B, thereby restricting the lateral movement of the inner housing 2. can be done.

10, 11, 12A, and 12B are diagrams showing a connector 200 that is still another variation. In these figures, the same parts as those of the connector 1 described above are denoted by corresponding reference numerals. Differences from the connector 1 will be mainly described below. Items not described about the connector 200 are the same as those of the connector 1 .

The connector 200 has terminals 204 (see FIG. 11). As shown in FIG. 12A , the terminal 204 has 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 has 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 241 c extends outward in the front-rear direction from the lower portion of the first base portion 241 a and is positioned at the lower end of the terminal 204 . That is, in the terminal 204 on the front side, the board fixing portion 241c extends forward from the lower portion of the first base portion 241a. In the terminal 204 on the rear side, the board fixing portion 241c extends rearward from the lower portion of the first base portion 241a. Also, in the terminal 204 on the front side, the first engaging portion 241b extends upward from the front portion of the substrate fixing portion 241c. In the terminal 204 on the rear side, 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 opening upward when the outer fixing portion 241 is viewed in the left-right direction. The edge of the first engaging portion 241b (the edge on the side of the first base portion 241a) has a convex portion 241d (see FIG. 12B) that is caught in the groove 31a formed in the lower portion (wall portions 31B and 31F) of the outer housing 3. ) is formed.

As shown in FIG. 12A, the inner fixed portion 242 has a second base portion 242a connected to the elastic portion 243 and a portion 242b that is bent with respect to the second base portion 242a (partial 242b is referred to as a "bent portion"). In the terminal 204 , unlike the terminal 4 , the second base portion 242 a functions as an engaging portion that engages the inner housing 2 . Specifically, the second base portion 242a is formed with a protrusion 242c that protrudes in the thickness direction (horizontal direction) of the second base portion 242a. It is caught on the inner surface of (the terminal accommodating portion 231). The contact portion 244 extends upward from the bent portion 242b.

As shown in FIG. 12A, the elastic portion 243 has a portion (first extending portion 243a) extending upward from the outer fixing portion 241 and a portion extending upward from the inner fixing portion 242 (second extending portion 243a). It has an extending portion 243b) and a curved portion 243c curved in an arc 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 linear portion 243f extending in the front-rear direction from the inner fixing portion 242 (a portion extending in the front-rear direction toward the first extending portion 243a). , and a first straight portion 243g that bends at the end of the second straight portion 243f and extends upward. A space (see FIG. 11, connector accommodating portion 21) in which the mating connector 9 (see FIG. 7) is arranged is secured above the second straight portion 243f. A space E2 (see FIG. 11) is secured below the second linear portion 243f in which the outer fixing portion 241 is arranged when the inner housing 2 is displaced in the front-rear direction.

As shown in FIG. 12B, in the example of the terminal 204, unlike the example of the terminal 4, the first linear portion 243g extends obliquely upward and outward in the front-rear direction. That is, in the terminal 204 on the front side, the first straight portion 243g extends diagonally forward and upward from the second straight portion 243f, and in the terminal 204 on the rear side, the first straight portion 243g extends rearward from the second straight portion 243f. And it extends obliquely upward. This can prevent the curved portion 243c from entering the connector accommodating portion 21 when the position of the inner housing 2 is displaced in the front-rear direction. For example, it is possible to prevent the first straight portion 243g from tilting backward and the curved portion 243c from entering the connector accommodating portion 21 when the position of the inner housing 2 is shifted forward.

As shown in FIG. 12B, the terminal 204 has a first connection portion P1, which is a connection portion between the first extension portion 243a and the outer fixing portion 241, and a connection portion between the second extension portion 243b and the inner fixing portion 242. It has a second connection portion P2 which is a connection portion. As in 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 extension 243a has a portion P3 positioned forward or rearward with respect to the second connection P2 (the portion P3 is at the same height as the second connection P2). It is the part that is located at the bottom.). That is, the portion P3 of the terminal 204 located on the front side is located in front of the second connection portion P2, and the portion P3 of the terminal 204 located on the rear side is located behind the second connection portion P2. ing. The portion P3 is located outside the first connecting portion P1 in the front-rear direction. That is, the portion P3 of the terminal 204 located on the front side is located forward of the first connection portion P1, and the portion P3 of the terminal 204 located on the rear side is located behind the first connection portion P1. is doing. This structure increases the distance L3 between the first extending portion 243a and the second extending portion 243b. As a result, the inner housing 2 can be largely 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 straight portion 243e further extending from the inclined portion 243d. there is The inclined portion 243d obliquely extends outward and upward in the front-rear direction. That is, the inclined portion 243d of the terminal 204 located on the front side extends diagonally forward and upward, and the inclined portion 243d of the terminal 204 located on the rear side extends diagonally upward and rearward. growing. Due to this inclined portion 243d, the portion P3 is positioned further outward in the front-rear direction than the first connecting 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 located below the second connection portion P2 (in other words, the second connection portion P2). below the straight 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 terminal 204 on the front side and the front wall portion 31F of the outer housing 3, and the first extending portion of the terminal 204 on the rear side is secured. A gap G1 (see FIG. 11) is secured between 243a and the rear wall portion 31B. As a result, the elastic portion 243 is elastically deformable 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 positioned forward or rearward of the second connection portion P2.

Note that the shape of the terminal 204 is not limited to that shown in FIG. 12A and the like. For example, instead of the inclined portion 243d, the terminal 204 may have a substantially L-shaped portion that extends upward from the first connecting portion P1, 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, then bends and extends forward. Also, 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 extension 243a may extend upward from the substantially L-shaped portion.
