The reinforcing portion 26C of the protective wall 26 coincides with the position of the middle elastic portion 53 of the third terminal 5 in the front-rear direction, which is the extension direction of the protective wall 26 .
The intermediate elastic portion 43 of the first terminal 4 and the intermediate elastic portion 53 of the third terminal 5 have approximately the same height. The first curved portion 53B of the intermediate elastic portion 53 of the third terminal 5 is located more inward in the width direction than the first curved portion 43A of the intermediate elastic portion 43 of the first terminal 4. The top wall 26B covers the entire first curved portion 43A of the intermediate elastic portion 43 of the first terminal 4 from above, and covers a portion of the first curved portion 53B of the intermediate elastic portion 53 of the third terminal 5 from above.

The dimension in the front-rear direction, which is the extending direction of the protective wall 26, is smaller than the dimension between the pair of front-rear portions 22. As a result, the widthwise portion 23 is composed of a central portion 23C in which the protective wall 26 is formed, and an outer portion 23S formed lower than the central portion 23C. The height of the outer side portion 23S of the width direction portion 23 is the same as the height of the front and rear direction portion 22. The above-described third terminal holding portion 25B is formed on the outer side portion 23S of the width direction portion 23.

<Movable housing 3>
The movable housing 3 may be referred to as a main body 3A excluding the protruding guide portions 35, the front and rear protruding portions 36, the widthwise convex portions 37, and the accommodating recesses 39, which will be described later. For this reason, it can be said that the movable housing 3 is composed of the main body 3A, the pair of front and rear protruding guide portions 35, the pair of front and rear protruding portions 36, the pair of widthwise convex portions 37, and the four accommodating recesses 39.

The main body 3A is generally rectangular and has a pair of front-rear outer sides 3A1 whose normal direction faces outward in the front-rear direction, and a pair of widthwise outer sides 3A2 whose normal direction faces outward in the width direction. The main body 3A also has four connection surfaces 3A3 that diagonally connect the front-rear outer sides 3A1 and the widthwise outer sides 3A2. The front-rear outer sides 3A1, the widthwise outer sides 3A2, and the connection surfaces 3A3 each form the same plane over the entire vertical direction of the main body 3A. However, due to the influence of the storage recess 39 described below, the connection surfaces 3A3 are formed only on the upper part of the main body 3A.

An insertion space 31 into which a part (protruding wall 64) of the second connector 9 serving as a connection object is inserted is formed in the main body 3A of the movable housing 3. The insertion space 31 opens upward. By forming the insertion space 31 in the main body 3A, a pair of front-rear walls 32 opposed to each other in the front-rear direction with the insertion space 31 therebetween, and a pair of width walls 33 opposed to each other in the width direction with the insertion space 31 therebetween are formed in the main body 3A.
Hereinafter, the portion of the main body 3A of the movable housing 3 in which the insertion space 31 is formed will be referred to as the cylindrical portion 3U, and the portion in which the insertion space 31 is not formed (in other words, the portion below the bottom surface 31C of the insertion space 31 (see Figure 3)) will be referred to as the bottom portion 3L.

The main body portion 3A of the movable housing 3 has a first terminal placement portion 34 in which a portion of the first terminal 4 (the movable side held portion 44, the tip elastic portion 45, and the contact portion 46) is placed.
The first terminal placement portion 34 includes a terminal placement groove 34B formed on the widthwise inner surface of the width direction wall 33, and a terminal placement hole 34A formed in the bottom portion 3L of the movable housing 3 and penetrating in the vertical direction. be done. The movable side held portion 44 of the first terminal 4 is press-fitted and held in the terminal placement hole 34A, and the tip elastic portion 45 and the contact portion 46 of the first terminal 4 are placed in the terminal placement groove 34B. be done.

The main body portion 3A of the movable housing 3 has a third terminal arrangement groove 38 in which a part of the third terminal 5 (the movable-side held portion 54, the tip elastic portion 55, and the contact portion 56) is arranged.
The third terminal arrangement grooves 38 are grooves formed on the outer surface 3A1 of the main body 3A in the front-rear direction. The third terminal arrangement grooves 38 are formed with the inner side in the front-rear direction as the depth direction and the extension direction in the up-down direction. Two third terminal arrangement grooves 38 are formed on the front side of the movable housing 3 in the front-rear direction and two on the rear side of the movable housing 3 in the front-rear direction.

As shown in FIG. 11, the depth of the third terminal arrangement groove 38 changes depending on the position in the vertical direction, which is the extending direction. Specifically, the third terminal arrangement groove 38 has an upper part with a shallow groove depth, a lower part with a deep groove depth, and an intermediate part between the upper part and the lower part. A bottom surface 38A3 (lower bottom surface) at the lower portion of the third terminal arrangement groove 38 is located inside the bottom surface 38A1 (upper bottom surface) at the upper portion in the connector longitudinal direction. The lower bottom surface 38A3 and the upper bottom surface 38A1 both extend in parallel in the vertical direction. A bottom surface 38A2 (middle portion bottom surface) in the intermediate portion of the third terminal placement groove 38 connects the upper bottom surface 38A1 and the lower bottom surface 38A3, and is inclined downwardly and inward in the connector longitudinal direction. The position of the lower bottom surface 38A3 in the front-rear direction substantially coincides with the inner surface of the front-rear wall 32 in the front-rear direction.

The movable side held portion 54 of the third terminal 5 is press-fitted and held in the lower portion of the third terminal arrangement groove 38, and the contact portion 56 of the third terminal 5 is placed in the upper portion of the third terminal arrangement groove 38. The movable side held portion 54 of the third terminal 5 is placed close to the bottom surface 38A3 at the lower portion of the third terminal arrangement groove 38.

The third terminal arrangement groove 38 has a groove width changing portion 38B in which the groove width dimension (dimension in the connector width direction) changes. A portion of the third terminal arrangement groove 38 above the groove width changing portion 38B has a groove width smaller than a portion below the groove width changing portion 38B. In a portion of the third terminal arrangement groove 38 other than the groove width changing portion 38B, the groove width dimension is constant over the vertical direction, which is the extending direction. The groove width changing portion 38B is formed below the position where the contact portion 56 of the third terminal 5 is located and above the position where the first extension portion 55A of the tip elastic portion 55 is located. .

The movable housing 3 has a protruding guide portion 35 that guides the connection with the second connector 9.
The protruding guide portion 35 protrudes upward with respect to the main body portion 3A. A pair of protruding guide portions 35 are formed at the front and rear. The protruding guide portion 35 is formed at a position outside the insertion space 31 in the front-rear direction, and is not formed at a position overlapping the insertion space 31 in the front-rear direction. On the other hand, the protruding guide portion 35 is formed not only at a position overlapping the insertion space 31 in the width direction but also at a position outside the insertion space 31 in the width direction. The width dimension of the protruding guide portion 35 matches the width dimension of the main body portion 3A of the movable housing 3. The protruding guide portion 35 has a top surface 35A facing upward, and an inclined surface 35B connected to the side surfaces 3A1, 3A2, and 3A3 of the main body portion 3A of the movable housing 3.

The movable housing 3 has a front and rear protrusion 36 (restricted part) for regulating the upward movement range of the movable housing 3.
The front and rear protrusions 36 are formed at the lower end of the movable housing 3. The front-back protrusion 36 projects outward in the front-back direction with respect to the front-back outer surface 3A1 of the main body 3A of the movable housing 3. The front and rear protrusions 36 are arranged in the restraining recesses 24 of the fixed housing 2.
A terminal passage hole 36A penetrating in the vertical direction is formed in the front and rear protrusion 36 at a position corresponding to the third terminal arrangement groove 38. The terminal passage hole 36A is configured so that the contact portion 56 of the third terminal 5 can pass therethrough when the third terminal 5 is attached to the movable housing 3.

The movable housing 3 has a widthwise convex portion 37 (impedance adjusting portion) that protrudes outward in the width direction, that is, in the direction approaching the intermediate elastic portion 43 of the first terminal 4 .
The width direction protrusion 37 protrudes outward in the width direction from the width direction outer side surface 3A2 of the main body portion 3A of the movable housing 3. The width direction protrusion 37 protrudes toward the intermediate elastic portion 43 of the first terminal 4, thereby functioning to reduce the impedance of the intermediate elastic portion 43 of the first terminal 4.
The widthwise protrusion 37 has an opposing surface 37A opposing the intermediate elastic portion 43 of the first terminal 4. The opposing surface 37A is composed of an upper portion 37A1, which is a surface whose normal direction faces outward in the width direction, and a lower portion 37A2, which is a surface whose normal direction faces a direction slightly inclined downward with respect to the outward in the width direction. As a result, the protrusion amount (protrusion amount outward in the width direction) of the upper portion of the widthwise protrusion 37 is constant in the up-down direction, and the protrusion amount of the lower portion of the widthwise protrusion 37 gradually decreases toward the bottom. The straight portion 43B of the intermediate elastic portion 43 of the first terminal 4 is located on the widthwise outer side of the widthwise protrusion 37.

As shown in FIG. 10, the widthwise convex portion 37 is located at the end of a plurality of intermediate elastic portions 43 (intermediate elastic portions 43 of the first terminal 4, which are first intermediate elastic portions) arranged in the front-rear direction, which is the arrangement direction. It is formed in a range overlapping in the arrangement direction with one or more (plurality in the figure) intermediate elastic parts 43 excluding the intermediate elastic part 43 . As a result, the impedance of the intermediate elastic portion 43 is reduced by the width direction convex portion 37 in one or more (in the figure, a plurality of) first terminals 4 on the center side in the arrangement direction. Therefore, it is preferable that at least the two first terminals 4 at the ends in the arrangement direction are used as a power supply terminal or a ground terminal.

(Accommodation recess 39)
The movable housing 3 has an accommodation recess 39 in which the intermediate elastic portion 53 of the third terminal 5 is accommodated. The accommodation recess 39 is formed to be recessed inward in the width direction with respect to the widthwise outer surface 3A2 of the main body 3A of the movable housing 3. The accommodation recesses 39 are formed on both sides in the front and back direction of the pair of widthwise outer surfaces 3A2 of the main body 3A of the movable housing 3. The accommodation recess 39 is opened not only outward in the width direction but also outward in the front-rear direction and downward.

The vertical dimensions of the movable housing 3 are greater than the vertical dimensions of the fixed housing 2. As a result, a portion of the upper part of the movable housing 3 is positioned to protrude upward relative to the fixed housing 2.

<Detailed configuration of second connector 9>
The detailed configuration of the second connector 9 will be explained.

≪Second terminal 7≫
The plurality of second terminals 7 are comprised of a plurality of second terminals 7 on one side in the width direction and a plurality of second terminals 7 on the other side in the width direction. Although the second terminal 7 on one side in the width direction and the second terminal 7 on the other side in the width direction have the same structure, they are arranged in positions facing each other in the width direction.

As shown in FIG. 3 , the second terminal 7 extends in the vertical direction and has an insertion portion 71 that is inserted into the second housing 6 , and a non-insertion portion 72 that is not inserted into the second housing 6 .
The thickness direction of the insertion portion 71 is oriented in the width direction. The non-insertion portion 72 extends outward in the width direction from an upper end of the insertion portion 71. The non-insertion portion 72 has a board fixing portion 72A that is fixed to the second board.

The insertion portion 71 is fitted with a first extension portion 71A accommodated in a terminal passage hole formed in the mounting housing 6A and a second extension portion 71B accommodated in a terminal passage hole formed in the fitting housing 6B. 71C of third extension parts arrange|positioned in the terminal arrangement groove formed in the protrusion wall 64 of the housing 6B. The third extension portion 71C contacts the first terminal 4 of the first connector 1.

≪Fourth terminal 8≫
As shown in FIG. 8, the plurality (four) of fourth terminals 8 are comprised of a pair of fourth terminals 8 on one side in the front-back direction and a pair of fourth terminals 8 on the other side in the front-back direction.

The fourth terminal 8 includes an insertion portion 81 that extends in the vertical direction and is inserted into the second housing 6, and a non-insertion portion 82 that is not inserted into the second housing 6.
The insertion portion 81 has its thickness direction oriented in the front-rear direction. The non-insertion portion 82 extends outward from the upper side of the insertion portion 81 in the front-rear direction.

As shown in FIG. 8, the insertion portion 81 of the fourth terminal 8 has a first extension portion 81A that is accommodated in a terminal passing hole formed in the mounting housing 6A, a second extension portion 81B that is accommodated in a terminal passing hole formed in the mating housing 6B, and a third extension portion 81C that is formed in the guide protrusion 62 of the mating housing 6B and is arranged in the fourth terminal arrangement groove. The third extension portion 81C contacts the third terminal 5 of the first connector 1.

≪Second housing 6≫
The second housing 6 includes a fitting housing 6B that constitutes the lower part of the second housing 6, and a mounting housing 6A that constitutes the upper part of the second housing 6.

The mating housing 6B has a base 65 (see FIG. 3), peripheral walls 62 and 63 extending downward from the periphery of the base 65, and a protruding wall 64 protruding from the center of the base 65.

A fitting recess 61 in which the movable housing 3 of the first connector 1 is disposed is formed in the fitting housing 6B. The fitting recess 61 is a space below the base 65 of the fitting housing 6B, and is a space surrounded by the peripheral walls 62 and 63.

The protruding wall 64 stands downward from the bottom surface of the mating recess 61. The protruding wall 64 is a wall that extends in the front-rear direction. A plurality of terminal arrangement grooves are formed in a pair of wall surfaces in the wall thickness direction (connector width direction) of the protruding wall 64, lined up in the front-rear direction, and the third extension portion 71C of the second terminal 7 is arranged in these terminal arrangement grooves.

The peripheral walls 62, 63 include a pair of guide protrusions 62 that constitute both ends of the peripheral walls 62, 63 in the front-rear direction, and a pair of connecting walls 63 that connect both widthwise ends of the pair of guide protrusions 62 in the front-rear direction. It consists of and.
The guide protrusion 62 is formed higher than the connecting wall 63. The connecting wall 63 connects the upper portions of the pair of guide protrusions 62 to each other. The height of the guide protrusion 62 is higher than the protruding wall 64, and the height of the connecting wall 63 is lower than the protruding wall 64.

The pair of guide protrusions 62 are the first parts to come into contact with the movable housing 3 of the first connector 1 when the first connector 1 and the second connector 9 are connected. The contact between the guide protrusions 62 and the movable housing 3 eliminates misalignment in the front-rear or width direction between the movable housing 3 and the second housing 6.

A fourth terminal arrangement groove is formed on the inner wall surface of the guide protrusion 62 in the front-rear direction, in which the third extension portion 81C of the fourth terminal 8 is arranged. Two fourth terminal holding grooves are formed on each of the pair of guide protrusions 62, for a total of four fourth terminal holding grooves.

The mounting housing 6A has a generally rectangular parallelepiped shape. The mounting housing 6A has a vertically elongated shape, and the vertical dimension of the mounting housing 6A is greater than the width dimension of the mounting housing 6A.

(Detailed structure of guide protrusion)
Next, the detailed structure of the guide protrusion 62 will be described.

As shown in FIG. 12, the guide convex portion 62 has a top surface 62A that constitutes the lower end of the guide convex portion 62. As shown in FIG. The normal direction of the top surface 62A is directed downward. The width dimension of the top surface 62A is approximately the same as the width dimension of the peripheral walls 62 and 63 (coinciding with the width dimension of the second housing 6). Note that the widthwise outer surface of the guide convex portion 62 and the widthwise outer surface of the connecting wall 63 form the same plane. Therefore, the outer shape of the peripheral walls 62 and 63 is rectangular in plan view.

The guide protrusion 62 has inner surfaces 62B1, 62B2, and 62B3 as inner surfaces in the front-rear direction.
The inner surfaces 62B1, 62B2, 62B3 have a first inner surface 62B1 that constitutes the widthwise center, a pair of third inner surfaces 62B3 that constitute the widthwise outer sides, and a pair of second inner surfaces 62B2 that diagonally connect the first inner surface 62B1 and the pair of third inner surfaces 62B3.
The first inner side surface 62B1 and the third inner side surface 62B3 have a normal direction facing inward in the front-rear direction. The pair of third inner side surfaces 62B3 are located more inward in the front-rear direction than the first inner side surface 62B1. The pair of second inner side surfaces 62B2 have a normal direction facing in a direction inclined inward in the width direction with respect to the inner side in the front-rear direction. The first inner side surface 62B1, the third inner side surface 62B3, and the second inner side surface 62B2 all extend in the up-down direction.
The connecting wall 63 connects the upper parts of the pair of guide protrusions 62 to each other at a position corresponding to the third inner side surface 62B3 of the guide protrusions 62.

The guide protrusion 62 has inclined surfaces 62C1, 62C2, and 62C3 that connect the top surface 62A to the inner surfaces 62B1, 62B2, and 62B3 at an angle.

The inclined surfaces 62C1, 62C2, and 62C3 have a first inclined surface 62C1 that connects the first inner surface 62B1 and the top surface 62A, a second inclined surface 62C2 that connects the second inner surface 62B2 and the top surface 62A, and a third inclined surface 62C3 that connects the top surface 62A of the third inner surface 62B3. When connecting the first connector 1 and the second connector 9, the second inner surface 62B2 and the second inclined surface 62C2 function to align the widthwise positions of the movable housing 3 and the second housing 6. In other words, the second inner surface 62B2 and the second inclined surface 62C2 of the guide protrusion 62 function as a "widthwise guide portion" that guides the widthwise positions of the movable housing 3 and the second housing 6.

<Effect>
Next, the effects of this embodiment will be explained.

1 , in this embodiment, the connector pair includes a first connector 1 and a second connector 9 that connects to the first connector 1 from above. The first connector 1 includes a first terminal 4 and first housings 2 and 3 that hold the first terminal 4, and the second connector 9 includes a second terminal 7 and a second housing 6 that holds the second terminal 7.
The first housings 2, 3 include a fixed housing 2 whose position is fixed relative to the first board, and a movable housing 3 that is movable relative to the fixed housing 2. The first terminal 4 has a first fixed-side held portion 42 held by the fixed housing 2, a first movable-side held portion 44 held by the movable housing 3, and a first intermediate elastic portion 43 located between the first fixed-side held portion 42 and the first movable-side held portion 44.

The first housings 2 and 3 have a protective wall 26 that protects the first intermediate elastic portion 43, and the second housing 6 has a pair of guide protrusions 62 that protrude downward. The pair of guide protrusions 62 guide the connection by coming into contact with the movable housing 3 during connection.
Furthermore, as shown in FIG. 9, the first connector 1 and the second connector 9 can be connected such that the lower ends (top surface 62A) of the pair of guide protrusions 62 are located below the upper end of the protective wall 26. It is.
Therefore, it is possible to provide a connector pair that can be connected deeply while ensuring the height of the protective wall 26 and the guide convex portion 62.

Further, in this embodiment, as shown in FIG. 10, the protective wall 26 extends in the direction in which the pair of guide protrusions 62 face each other (front-back direction), and the protective wall 26 extends in the direction in which the protective wall 26 extends. The dimension L1 is smaller than the distance L2 between the pair of guide protrusions 62. Then, in a state where the first connector 1 and the second connector 9 are connected and in a normal state (the state shown in FIG. 10, that is, the state where the movable housing is not displaced in the front-back direction and the width direction), The protective wall 26 is located in the space between the guide protrusions 62.
Therefore, the guide convex portion 26 can be formed large in the width direction.

Further, in the present embodiment, the guide protrusion 62 includes a width direction guide part (a second inclined surface 62C2 of the guide protrusion 62, a second inner surface 62B2, see FIG. 12).
Therefore, during connection, the widthwise positional deviation between the movable housing 3 of the first connector 1 and the second housing 6 of the second connector 9 is eliminated by the widthwise guide portion.

Furthermore, in this embodiment, the protective wall 26 includes a side wall 26A that covers the first intermediate elastic section 43 from the side, and a ceiling wall 26B that covers the first intermediate elastic section 43 from above.
For this reason, the first intermediate elastic portion 43 can be protected more reliably than, for example, in a mode in which the protective wall 26 does not have the top wall 26B.

Further, in this embodiment, the first connector 1 includes a third terminal 5 having a different shape from the first terminal 4. Therefore, the third terminal 5 is suitable for use in a purpose different from that of the first terminal 4 (for example, for power supply, for grounding).
Further, since the third intermediate elastic portion 53 of the third terminal 5 is protected by the protective wall 26 that protects the first intermediate elastic portion 43 of the first terminal 4, for example, the first intermediate elastic portion 43 of the first terminal 4 The structure of the first housings 2 and 3 can be made simpler than the case where the third intermediate elastic portion 53 of the third terminal 5 is protected by a protection wall other than the protection wall 26 that protects the third terminal 5.

Next, the effects of this embodiment will be explained from another perspective.

In this embodiment, as shown in FIG. 11, the first connector 1 includes a side terminal 5 (third terminal 5) and first housings 2, 3. The side terminal 5 has a held portion 54 held by the first housings 2, 3, a contact portion 56 that contacts the connection object 9, and a tip elastic portion 55 that is positioned between the held portion 54 and the contact portion 56. The first housings 2, 3 have a terminal arrangement groove 38 formed in the side surface 3A1 in the front-rear direction, and the held portion 54, contact portion 56, and tip elastic portion 55 of the side terminal 5 are arranged in the terminal arrangement groove 38.

Here, the terminal arrangement groove 38 includes an upper portion having an upper bottom surface 38A1 located on the inner side in the front-rear direction relative to the contact portion 56, and a lower portion having a lower bottom surface 38A3 located on the inner side in the front-rear direction relative to the held portion 54. The lower bottom surface 38A3 is located on the inner side in the front-rear direction relative to the upper bottom surface 38A1.
This allows the retained portion 54 of the side terminal 5 to be moved inward in the front-to-rear direction while ensuring a large area on the inner side in the upper part of the housing (the area on the inner side in the front-to-rear direction relative to the upper bottom surface 38A1, for example the area where the insertion space 31 is formed).

Further, in this embodiment, the first housings 2 and 3 include a fixed housing 2 fixed to an attachment target (first board) and a movable housing 3 movable with respect to the fixed housing 2. The terminal arrangement groove 38 is formed in the movable housing 3.
Further, as shown in FIG. 7, the side terminal 5 includes a fixed side held part 52 held by the fixed housing 2, a movable side held part 54 as a held part 54, and a fixed side held part 52. and an intermediate elastic portion 53 located between the movable side held portion 54 and the movable side held portion 54 . The intermediate elastic portion 53 is aligned with the movable held portion 54 in the front-rear direction.
Therefore, in a floating connector including the intermediate elastic portion 53 whose position in the front-rear direction matches that of the movable held portion 54, the intermediate elastic portion 53 can be moved inward in the front-rear direction.

Moreover, in this embodiment, the first connector 1 includes a plurality of first terminals 4 and a third terminal 5 as a side terminal 5. The first intermediate elastic portions 43 of the plurality of first terminals 4 are arranged with the front-rear direction as the arrangement direction.
Here, the fixed housing 2 has a protection wall 26 that extends in the front-rear direction and protects the plurality of first intermediate elastic parts 43 and the intermediate elastic part 53 of the third terminal 5.
Therefore, since the intermediate elastic portion 53 can be located on the inside in the front-rear direction, the dimension of the protective wall 26 in the extending direction can be reduced.

In addition, in this embodiment, as shown in FIG. 11, the terminal arrangement groove 38 has an intermediate bottom surface 38A2 that connects the upper bottom surface 38A1 and the lower bottom surface 38A3, and the intermediate portion bottom surface 38A2 is used for inserting the connection target object 9. The lower end 31C of the insertion space 31 overlaps with the lower end 31C of the insertion space 31 in the vertical direction.
Therefore, while ensuring the depth of the insertion space 31, the held portion 54 of the side terminal 5 can be positioned on the inside in the front-rear direction.

Further, in the present embodiment, the tip elastic portion 55 includes a first extension portion 55A having a large inclination in the vertical direction, and a second extension portion 55B having a small inclination in the up-down direction.
Therefore, it is easy to increase the slope of the intermediate portion bottom surface 38A2. As a result, while ensuring the depth of the insertion space 31, the held portion 54 of the side terminal 5 can be moved further inward in the front-rear direction.

[Supplementary explanation of the above embodiment]
Note that in the above embodiment,
Although an example has been described in which the first board and the second board are arranged parallel to each other with the connector pair in between when the first connector 1 and the second connector 9 are connected, the present disclosure is not limited thereto.

Further, in the above embodiment, an example has been described in which the housing is held with respect to the terminal by press-fitting, but the housing may be held by insert molding.

In addition, in the above embodiment, an example (see Figure 10) was described in which the protective wall 26 is located in the space between a pair of guide protrusions 62 when the first connector 1 and the second connector 9 are connected and in the normal state, but the present disclosure is not limited to this.
For example, when the first connector 1 and the second connector 9 are connected and in the normal state, the protective wall 26 is not positioned in the space between a pair of guide protrusions 62, but the protective wall 26 may be able to be positioned in the space between the pair of guide protrusions by moving the movable housing 3 relative to the fixed housing 2.
Also, for example, the protective wall 26 may not be positioned in the space between a pair of guide protrusions 62, and even if the movable housing 3 moves relative to the fixed housing 2, the protective wall 26 may not be positioned in the space between the pair of guide protrusions.

In addition, in the above embodiment, an example in which the protective wall 26 is formed on the fixed housing 2 is described, but the present disclosure is not limited to this. The protective wall may be formed on the movable housing.

In addition, in the above embodiment, as shown in Figure 10, an example was described in which the widthwise convex portion 37 is formed in a range that overlaps in the arrangement direction with one or more (multiple in the figure) intermediate portions 43 out of the multiple intermediate portions 43 lined up in the front-to-rear direction, which is the arrangement direction, excluding the end intermediate portions 43, but the present disclosure is not limited to this.
Although not shown in the drawings, the width direction convex portion 37 may be formed in a range overlapping with all of the intermediate portions 43 in the arrangement direction among the multiple intermediate portions 43 lined up in the arrangement direction.

By the way, when the movable housing 3 is displaced in the arrangement direction (back and forth direction) with respect to the fixed housing 2, the position of the movable housing 3 in the arrangement direction with respect to the intermediate part 43 (especially the straight part 43B, see FIG. 6) of the terminal 4 also changes. Change. Therefore, even if the widthwise convex portion 37 is formed in a range overlapping with all the intermediate portions 43 in the arrangement direction among the plurality of intermediate portions 43, the amount of displacement of the movable housing 3 in the arrangement direction (back and forth direction) with respect to the fixed housing 2 In some cases, the intermediate portion 43 at the end may not face the widthwise convex portion 37, and the impedance adjustment effect may not be achieved at the terminal 4 at the end.
Therefore, although not shown in the drawings, the width direction convex portion 37 may be formed in a range that has more margin than the range overlapping with all the intermediate portions 43 in the arrangement direction. Specifically, with respect to the range L1 in the arrangement direction in which the plurality of intermediate parts 43 are arranged, the range L2 in which the width direction convex parts 37 are formed is the dimension in the arrangement direction of one intermediate part 43 (the width enlarged part 43B1). It is preferable that the intermediate portions 43 be formed with a margin greater than (L2-L1>2w, where w is the dimension of the intermediate portion 43 in the array direction).
