Description

Electrical connector {ELECTRIC CONNECTOR}

The present invention relates to an electrical connector that selectively accepts fittings of two mating connectors having different appearances in one fitting port formed for receiving a fitting of a mating connector. .

As this kind of electrical connector, the connector disclosed by patent document 1 is known. This patent document 1 discloses the electrical connector which has the fitting opening which can accommodate two mating connectors in which a fitting part has a different external shape, The said fitting opening is a contour suitable for the fitting part of one mating connector, It is formed as an opening of the form which overlaps the outline suitable for the fitting part of the other mating connector. Therefore, the one outline and the other outline partially form each other.

In the connector of patent document 1 which has such a fitting, the terminal is arrange | positioned in the space formed by the one contour and the other contour partially protruding from each other. Specifically, the space is formed at two positions of the upper and lower portions of the fitting port, and therefore, the terminals corresponding to the terminals of the mating connectors are arranged at these two positions. When one mating connector is fitted, it is connected with the upper terminal, and when the other mating connector is fitted, it is connected with the lower terminal.

Japanese Patent Application Laid-open No. Hei 6-243922

However, in the connector of Patent Literature 1, the terminals are arranged at the upper and lower portions exclusively for each of the two mating connectors. The terminals are often arranged in a plurality. Therefore, in the connector of this patent document 1, since dedicated terminals are arranged with respect to two mating connectors, not only does a component score increase remarkably but also a connector becomes high by that, leading to the enlargement of a connector.

In order to cope with this, it is also possible to form a fitting in the housing of the connector so that the terminals of two different mating connectors are in the same position so that both connectors can be fitted, and the common terminals can be arranged in the fitting. Do.

In this case, however, even when one of the two other mating connectors is fitted, a portion, i.e., a space that is at least partially separated between the fitting opening and the mating connector, may cause the connectors to rattle in this space. .

In view of the above circumstances, the present invention provides a electrical connector that can share a terminal with two other mating connectors, and which can be fitted without any rattling between any mating connectors. Shall be.

The electrical connector according to the present invention makes it possible to selectively accommodate the fitting portions of two mating connectors having different appearances in one fitting opening which is opened in the housing to accommodate the fitting portion of the mating connector.

In such an electrical connector, in the present invention, a common terminal in which a contact portion is arranged at a position that can be in contact with the terminals of any mating connector is arranged in the housing, and the fitting port is perpendicular to the connector fitting direction. In view of the above, it has a first accommodating area for accommodating a first mating connector and a second accommodating area for accommodating a second mating connector, wherein the housing is provided with a displacement permissible region that permits displacement of the elastic displacement portion formed in the fitting opening. Formed outside the first accommodating area as a space communicating with the first accommodating area, the second accommodating area is inherent in the first accommodating area, and the elastic displacement portion is accommodated in the first mating connector. It is elastically displaced so that it may be pressed by the said 1st mating connector and it may move to a displacement tolerance area | region, and it is pressed by a 2nd mating connector at the time of accommodating a 2nd mating connector. To do or do not elastically displaced or such a second mating connector is pressed, at least a part is characterized in that the resilient displacement so as to move toward the displaced allowable area while remaining in the first receiving area.

According to this invention of such a structure, an elastic displacement part forms a part of the inner wall which forms the space which allows the fitting part of a mating connector, and a fitting direction with respect to both a 1st mating connector and a 2nd mating connector. Or it regulates in the direction orthogonal to a fitting direction. Therefore, no rattling occurs in the fitting for either connector.

In the first accommodating area accommodating the first mating connector, there is a second accommodating area accommodating the second mating connector. In other words, the fitting portion of the first mating connector is larger than the fitting portion of the second mating connector.

When the first mating connector having this large fitting portion is fitted to the fitting opening, the elastic displacement portion is pressed by the first mating connector to be displaced in a direction perpendicular to the fitting direction or the fitting direction to enter the displacement allowable region. In the state, the position is regulated while allowing the first mating connector to fit.

At the time of fitting of the second mating connector, the elastic displacement portion is elasticated by an amount smaller than that in the case of allowing the fitting of the second mating connector without elastic displacement, or in other words, fitting of the first mating connector. It may displace and the fitting of the said 2nd mating connector may be allowed.

The case where the elastic displacement portion allows the fitting of the second mating connector without elastic displacement is a case where the elastic displacement portion is disposed outside the second accommodation region, although the elastic displacement portion is close to the second accommodation region. In this case, at the time of connector fitting, the second mating connector is regulated by the elastic displacement portion, but since the elastic displacement portion is not pressed, the elastic displacement portion does not elastically displace at all.

Next, a case where the elastic displacement portion is elastically displaced slightly to allow the fitting of the second mating connector is a case where a part of the elastic displacement portion enters and is located in the second accommodation region in the free state before the connector fitting. In such a case, when the connector is fitted, a part of the elastic displacement portion is pressed against the second mating connector to elastically displace to the limit position of the second receiving region, thereby allowing the second mating connector to be fitted at this position. Regulate position.

In this invention, the elastic displacement part can be made to be displaceable toward the inner wall surface of a fitting opening, or to the inner part of a fitting direction in one direction on the surface perpendicular | vertical to a fitting direction. The direction in which the elastic displacement is to be determined can be determined depending on which direction the elastic displacement portion and the space for the displacement amount can be secured and the environmental conditions imparted to the connector.

In the present invention, the elastic displacement portion can be formed integrally with the housing, that is, as part of the housing. In this case, since the elastic displacement portion is not a separate member with respect to the housing, the number of parts is reduced by that, and the connector can be made at low cost.

On the other hand, when a shield plate is attached to the housing of the connector, the elastic displacement portion can be formed integrally with the shield plate. That is, the elastic displacement portion can be formed as a part of the shield plate to sufficiently utilize the strength possessed by the metal plate. In addition, the elastic displacement portion itself can be miniaturized as much as the one made of a metal plate can be made thin rather than part of the housing made of synthetic resin.

In the present invention, when the elastic displacement portion is displaced in one direction on a plane perpendicular to the fitting direction, the elastic displacement portion extends from the inner portion of the fitting opening toward the opening, and the edge portion of the arm-shaped portion is different. It is possible to form a restricting portion that can abut against one mating connector. In this case, since the restricting portion can be formed long in the fitting direction, the attitude of the mating connector is stabilized at the time of fitting or even when the balanced conductor is tensioned and a sudden force is applied to the mating connector. The said arm-shaped part can be made also as a part of a housing | casing, or a part of a shield plate.

In addition, when the elastic displacement portion is displaced toward the inner portion in the fitting direction, the elastic displacement portion can be a coil spring that is pressed by the mating connector and compressible toward the inner portion.

In this invention, it is preferable that the front end of the said elastic displacement part is located outside the opening range of a fitting opening when the elastic displacement part is seen from a fitting direction. In this way, the mating connector abuts against the tip and does not cause buckling in the elastic displacement portion, and the mating connector abuts against the elastic displacement portion at a position inward of the tip in the fitting direction, thereby providing the elastic displacement. Since the part is pressed toward the displacement allowable area, the elastic displacement part is smoothly displaced.

In the present invention, when the arm portion of the elastic displacement portion is made as part of the shield plate, the restricting portion can be formed on the plate thickness surface of the arm portion. This improves the intensity at the time of regulation.

In this invention, it is preferable that the elastic displacement part is formed in the both end side of a terminal arrangement direction. By doing so, the mating connector is fitted in a more stable posture.

The present invention, as described above, with respect to the two other mating connectors, by arranging the terminals in the common position and by placing the elastic displacement portion in the fitting opening, the displacement of the elastic displacement portion relative to one of the mating connectors and the other Since one part of the mating connector is formed in a free state without any displacement or in a state with slight displacement, each part of the inner wall of the formation of the fitting allowable space is formed, thereby reducing the cost and miniaturization of the connector by preventing the increase in the number of terminals. This can achieve the effect that there is no rattling when fitting with either mating connector.

FIG. 1: is a perspective view which shows the connector 1 of this embodiment and the 1st mating connector 2 fitted to this in the state before fitting. Both connectors 1 and 2 are broken perspective views at terminal positions in the intermediate portion in the arrangement direction of the terminals, and only half portions thereof are shown. The connector 1 of this embodiment can selectively fit the 2nd mating connector 3 (refer FIG. 4 (b)) which is not shown in FIG. 1 instead of the said 1st mating connector 2. It is supposed to be done.

The connector 1 of this embodiment includes a housing 10 made of an electrical insulating material, a metal terminal 20 supported by the housing 10, and a metal plate shield attached to the housing 10. It has a plate 30.

As shown in FIG. 1, the housing 10 has an island in the concave portion 11 whose outer shape is substantially rectangular parallelepiped and opens toward the side of the first mating connector 2 that is a mating partner. It has the terminal arrangement part 12 which forms and extends toward the opening side of the said recessed part 11 from the inner part of the said recessed part 11. Therefore, the said recessed part 11 forms the space of the form surrounding the periphery of the island-shaped terminal arrangement part 12. As shown in FIG. The recessed part 11 is a 1st accommodating area which accommodates the fitting part of the 1st mating connector 2, the 2nd accommodating area which accommodates the fitting part of the 2nd mating connector 3, as mentioned later, and It is formed for three regions of the displacement allowable region for the elastic displacement portion (arm-shaped portion 34) described later, which is part of the shield plate 30.

FIG. 2 is a three-dimensional view conceptually showing the space of the concave portion 11 forming the three regions I, II, and III as a double-dotted dashed line forming an appearance for convenience. The direction of viewing this space is the same as in the case of FIG.

In FIG. 2, the three-dimensional area | region shown by the code | symbol (I) is a 1st accommodating area, and code | symbol (II) is a 2nd accommodating area | region. 1st accommodating area | region I is an area | region used for accommodating the fitting part of 1st mating connector 2, when viewed from the connector fitting direction A, and 2nd accommodating area | region II is another mating connector, That is, it is an area used for accommodating the fitting portion of the second mating connector 3. In the present invention, the fitting portion of the first mating connector 2 is larger in appearance than the fitting portion of the second mating connector 3, and the second housing for the latter is included in the first accommodating region I for the former. As the region (II) is inherent, it has a size and positional relationship with each other. Therefore, in the housing 10 of FIG. 1, the fitting opening which is common to both mating connectors 2 and 3 is formed in the shape where the 1st larger 1st accommodating area | region I is large.

In FIG. 2, the displacement tolerance area | region for the elastic displacement part of the shield plate 30 in communication with the said 1st accommodating area I on the side of the said 1st accommodating area I outside the said 1st accommodating area I. (III) is formed. Therefore, a space in which both the first accommodating region I and the two regions of the displacement allowable region III inherent in the second accommodating region II are formed is formed in the housing 10 as the recess 11. . Even if the displacement allowable region III is not a displacement allowable region III located on the side of the first accommodating region I, the displacement allowable positioned inwardly of the first accommodating region I can be located. It is good also as area | region III '.

As can be seen in FIGS. 1 and 4 (a), a terminal arrangement groove 13 for arranging the contact portion 21 of the terminal 20 is formed on the upper surface of the island-shaped terminal arrangement portion 12. have. As shown in Fig. 4 (a), the terminal 20 has a mountain-shaped contact portion 21, a to-be-supported portion 22 extending in the inner part direction of the housing 10, and a lower portion outside the housing 10. The lower end is crank-shaped and has the connection part 23 which forms a horizontal part. As for the said contact part 21 of a mountain shape, the top part protrudes upwards from the said terminal arrangement groove 13, and the front-back part of the said government part is accommodated in the terminal arrangement groove 13. As shown in FIG. The terminal 20 is inserted and assembled from the inner partial wall portion 14 side (rear) of the housing 10, and is assembled to the upper surface of the inner partial wall portion 14, and further to the outer surface of the inner partial wall portion 14. It is supported by the formed support groove. In this way, the connection part 23 is at the same level as the lower surface of the housing 10 in the supported state, and when the connector 1 is arrange | positioned on a circuit board, it becomes possible to solder-connect with the corresponding circuit part of a circuit board. The series of terminals 20 arranged in this way are common to both the first mating connector 2 and the second mating connector 3. In this embodiment, although the connector 1 is attached horizontally with respect to a circuit board, you may attach vertically with respect to a circuit board.

On the upper and lower surfaces thereof, the housing 10 has an edge surrounded by both side circumferences and a front circumference which becomes the mating connector side to form an end, and a portion surrounded by the rim width The shield plate arrangement portions 15 and 16 are each formed in a depth corresponding to the plate thickness of the shield plate 30.

As can be seen well in FIG. 3, the shield plate 30 is made by bending a metal plate after forming an outer shape by, for example, punching. The shield plate 30 includes an upper plate portion 31, a lower plate portion 32, a side plate portion 33 connecting the upper plate portion 31 and a lower plate portion 32 from the side portion, and the side plate portion 33 of the housing. It has the arm-shaped part 34 in which the elastic displacement part 42 which bends in the inner part side peripheral part and extends forward is formed.

The upper plate portion 31 has contact arms 35 which are bent inwardly and extend in front of a plurality of locations on the rear circumferential side, and the contact arms 35 are upper surfaces of the mating connectors when mating the mating connectors. Is in elastic contact with the shield plate. The upper plate portion 31 has a window 36 and a fixed arm 37 at a plurality of locations on the front circumferential side. The window portion 36 is for enabling displacement of the tip of the contact arm 35 when the contact arm 35 is engaged with the shield plate of the mating connector. The fixed arm 37 extends forward after being slightly bent downward, and protrusions 37A are formed on the upper surface thereof. The fixed arm 37 is pressed into an end formed in the front front circumference of the housing 10 by a slit (not shown) opened rearward to contribute to attachment to the housing.

The lower plate portion 32 also has a contact arm 38, a window portion 39, and a fixed arm 40, similarly to the upper plate portion 31. These contact arms 38, the window part 39, and the fixed arm 40 are arranged in the connector width direction (compared with the contact arm 35, the window part 36, and the fixed arm 37 of the upper plate part 31). Although they are shifted and set in the terminal arrangement direction, they are formed in the same manner only by forming the upper and lower symmetrical shapes with the upper plate portion 31, and their functions are also the same as those in the upper plate portion.

The side plate portion 33 has an upper portion 33A and a lower portion 33B that are crank-shaped in the plate thickness direction, and when the shield plate 30 is attached to the housing 10 from the rear, the upper portion 33A is The lower part 33B is located in the outer surface side of the housing 10 on the inner surface side of the housing 10 (side wall inner surface side of the recess 11) (refer FIG. 6). The arm-shaped portion 34 extends from the rear circumferential side of the lower portion 33B so that the rear portion 41 extends so that the inner surface and the plate surface of the lower portion 33B are parallel to each other. It extends toward the opening and is elastically displaceable in the plate thickness direction, and the front part of the said arm-shaped part 34 is bent in a crank shape in the plate thickness direction, and it is inward of the recessed part 11 of the housing 10. As shown in FIG. The projecting elastic displacement part 42 is comprised. The rear portion 41 is located in the displacement allowable region III outside the first accommodation region I in the recess 11 of the housing, as viewed from the connector fitting direction, and the elastic displacement portion ( 42 is located in the first accommodation area I from the displacement allowable area III. The rear portion 41 and the elastic displacement portion 42 are outside the second accommodation region II in relation to the second accommodation region II, and have an upper circumference of the elastic displacement portion 42. 42A is adjacent to the lower periphery of the said 2nd accommodating area | region. This elastic displacement part 42 is pressed by the 1st mating connector by the 1st mating connector in the plate surface of the part which protrudes to the said 1st accommodating area | region I with respect to the 1st mating connector accommodated in 1st accommodating area | region I. 2nd mating connector elastically displaces and is not pressed by the 2nd mating connector with respect to the 2nd mating connector accommodated in the 2nd accommodating area | region II, and allows insertion of a 2nd mating connector by itself, without any displacement. Then, at the time of insertion, the restricting portion 42A is formed to guide the insertion while restricting the second mating connector in the vertical direction at the upper periphery (plate thickness surface).

As can be seen from FIG. 8 (a), the front end of the elastic displacement portion 42 is located at the rear side of the opening circumference of the recess 11 of the housing 10, and the At the time of entry, the mating connector does not collide with the front end 42C, and is guided by the front side inclined surface 42B of the elastic displacement part 42.

On the other hand, as shown also in FIG. 1, the 1st mating connector 2 has the housing 50 in which the fitting recessed part 51 was formed in the front, and the tapered shape was formed in the front surface of the side end part. The guide part 52 is formed. The fitting recess 51 accommodates the island-shaped terminal arrangement 12 of the connector 1 and at the same time, the front peripheral wall of the housing 50 which forms the fitting portion 50A. The guide portion 52 enters the first accommodating region I, which is a space of the concave portion 11 surrounding the terminal arrangement portion 12 of the connector 1. On the inner surface of the upper wall forming the upper side of the fitting recess 51, the terminal 53 in contact with the contact portion 21 of the terminal 20 of the connector 1 (Fig. 4 (a)). Contact portion 53A is arranged corresponding to the terminal 20 of the connector 1. The rear portion of the terminal 53 is connected to the balanced conductor P1 in the inner space of the housing, and the balanced conductor P1 is directed outward from the housing.

As for the said 1st mating connector 2, the shield case 54 which consists of the upper case 55 and the lower case 56 made from a metal plate is attached to the main-body part 50B of the housing 50. As shown in FIG. The upper case 55 and the lower case 56 are in contact with each other at their rear portions, and the upper case 55 reaches near the front end of the fitting portion 50A of the housing, so that the upper case 55 is in contact with the upper case 55. The projection 55A makes contact with the contact arm 35 of the shield plate 30 of the connector 1 possible. In addition, the upper case 55 has the contact protrusion 55A on the upper surface and contacts a contact piece 58 which enters from the window portion 57 of the main body portion 50B of the housing 50. It is brought into contact with the ground layer of the upper surface of the said balanced conductor P1.

In the other mating connector, that is, the second mating connector 3, as shown in FIG. 4 (b), the fitting portion 60A is larger than the fitting portion 50A of the first mating connector 2. It is formed thin and has the same shape as the bottom half of the fitting portion 50A of the first mating connector 2 is cut out. Therefore, the fitting part 60A is accommodated in the 2nd accommodating area II formed in the upper half of the recessed part 11 of the connector 1, ie, the space above the island-shaped terminal arrangement part 12. FIG. do.

As for the said fitting part 60A, the shield plate 63 is arrange | positioned at the upper surface of the plate-shaped part 62 of the housing 60, and the equilibrium conductor P2 is arrange | positioned at the lower surface. At the side end, a guide portion 61 having a height dimension smaller than that of the guide portion 52 of the first mating connector 2 and having a tapered tip is formed. The bottom face of this guide part 61 is at the level located just above the upper periphery of the elastic displacement part 42 of the arm-shaped part 34 of the connector 1.

The main body portion 60B of the housing located behind the fitting portion 60A is formed thicker than the fitting portion 60A, and surrounds the shield plate 63 and the balanced conductor P2. The contact piece 64 is formed in the shield plate 63, and is in contact with the ground layer on the upper surface of the balanced conductor P2. The housing 60 covers the flat conductor P2 from the lower side by a lid-shaped lower housing 66 which is integrally rotatably connected by a flexible portion 65.

Next, the operation | movement at the time of selectively fitting the 1st mating connector 2 and the 2nd mating connector 3 with respect to this connector 1 of this embodiment is demonstrated.

(1) First, the first mating connector 2 is selected with respect to the connector 1, and this is fitted. 50A of fitting parts of the 1st mating connector 2 enter into the 1st accommodating area | region I in the recessed part 11 shown in FIG. The elastic displacement part 42 of the arm-shaped part 34 integrally formed with the shield plate 30 enters into the 1st accommodating area | region I. Therefore, the fitting part 50A of the 1st mating connector 2 is shown also in FIG. 6, pressing the said elastic displacement part 42 sideways at the side surface of the guide part 52 (a), and FIG. In the state of Fig. 8 (b). That is, the arm-shaped part 34 receives the force from this guide part 52 and elastically displaces itself, and allows the progression of the fitting of 50 A of fitting parts (refer FIG. 6). In this way, the contact portion 21 of the terminal 20 of the connector 1 is in contact with the contact portion 53A of the terminal 53 of the first mating connector 2, as shown in FIG. 5 (a). The contact arm 35 of the shield plate 30 of the connector 1 comes into contact with the contact protrusion 55A of the shield case 54 (upper case 55) of the first mating connector 2. The arm-shaped portion 34 may be attached to the housing separately from the shield plate 30.

(2) Next, instead of the first mating connector 2, the second mating connector 3 is fitted to the connector 1. The fitting portion 60A of the second mating connector 3 enters the second receiving region II as described above. When viewed from the connector fitting direction, the second accommodation region II is in the first accommodation region I, and the elastic displacement portion 42 is located in the first accommodation region I, but the It is outside the 2nd accommodating area II. Therefore, as shown in FIG. 7, the fitting part 60A does not press the elastic displacement part 42, ie, does not interfere with the elastic displacement part 42, FIG. Enters the second receiving region (II) toward the state of FIG. At that time, since the restricting portion 42A of the upper circumference of the elastic displacement portion 42 is located very close to the lower circumference of the second accommodating region II, the restricting portion 42A is fitted with the fitting portion 60A. Guide the lower side of the), smooth insertion without rattling is achieved. In this way, the contact portion 21 of the terminal 20 of the connector 1 is in contact with the corresponding contact portion of the balanced conductor P2 of the second mating connector 3, as can also be seen in FIG. 5 (b). The contact arm 35 of the shield plate 30 of the connector 1 comes into contact with the shield plate 63 of the second mating connector 3. At the time of fitting of the second mating connector 3, the recess 11 of the connector 1 remains in an empty position below the island arrangement terminal arrangement 12 (see FIG. 7). In addition, the elastic displacement portion may be elastically displaced slightly to allow the fitting of the second mating connector. In this case, the elastic displacement portion may enter a second accommodation area in a part of the elastic displacement portion in a free state before fitting the connector. It may be located so that. In such a case, when the connector is fitted, a part of the elastic displacement portion is pressed against the second mating connector to elastically displace to the limit position of the second receiving region, thereby allowing the fitting of the second mating connector at this position. Since the restricting part of the upper periphery of an elastic displacement part is located very close to the lower periphery of 2nd accommodating area | region II, it positions similarly.

<2nd embodiment>

In the first embodiment, the elastic displacement portion is made as part of the shield plate, but in this embodiment, it is characterized in that it is made as part of the housing. Therefore, this embodiment is suitable when the shield plate is to be made into a simple form without an elastic displacement part or when the connector does not have the shield plate.

As can be seen in FIG. 10 (a), the housing 10 has an arm-shaped portion 71 that extends forward as a part of the housing 10 from an inner portion thereof, and an elastic displacement portion whose front portion protrudes. 72 is formed. As in the case of the first embodiment of FIG. 8A, the front end 72C is positioned behind the opening circumference of the recess 11 of the housing 10. The connector does not collide with the front end 72C, and is guided by the front inclined surface 72B in the vicinity thereof.

Also in this second embodiment, when the first mating connector 2 is fitted, the arm-shaped portion 71 is pressed by the first mating connector 2 at the elastic displacement portion 72 to elastically displace. This allows the fitting of the first mating connector 2 as shown in Fig. 10 (b).

When the second mating connector 3 is fitted as shown in FIG. 11 (a), as shown in FIG. 11 (b), the second mating connector 3 pushes the elastic displacement portion 72. Without it, the fitting proceeds as it is. At that time, the second mating connector 3 is guided while being guided while being regulated by the upper circumference restricting portion 72A (surface parallel to the surface) of the elastic displacement portion 72 in the first embodiment. The same as in the case of the upper circumference restricting portion 42A of the elastic displacement portion 42 of FIG.

<Third embodiment>

In the first and second embodiments, the elastic displacement portion is formed to be located on the side of the concave portion 11 of the housing 10, but in the present embodiment, the displacement is allowed to be located inside the concave portion 11. It is characteristic in that it is formed in area | region III '. In addition, in this embodiment shown in FIG. 12, the elastic displacement part is not integral with the shield plate and the housing, but is formed separately.

In Fig. 12A, the displacement allowable region III 'is formed as an immersion portion 81 in the inner part of the housing. One end side of the compression coil spring 82 is accommodated in this immersion part 81, and this coil spring 82 extends to the front opening side of the recessed part 11 in a free state. On the other end side of the coil spring 82, a movable member 83 on which a front inclined surface portion 83A is formed is attached to be movable in the front-rear direction. The portion of the coil spring 82 and the movable member 83 extending forward outside the immersion portion 81 are in the first accommodating region I but outside the second accommodating region II. That is, it is located below the 2nd accommodating area | region II (back surface side with respect to the ground surface in the direction orthogonal to the ground surface in FIG. 12 (a)).

In this embodiment, when the first mating connector 2 is fitted, the tapered guide portion 52 of the first mating connector 2 sandwiches the movable member 83 as shown in FIG. 12 (b). By pressing in the alignment direction, the movable member 83 can be moved in the same direction, and the coil spring 82 can be compressed and pushed into the immersion part 81. In this way, the 1st accommodating area | region I for fitting of the 1st mating connector 2 is ensured, and a fitting is performed.

Next, as shown in Fig. 13A, when the second mating connector 3 is fitted, as shown in Fig. 13B, outside the second accommodating region II (the second accommodating region ( The movable member 83 and the coil spring 82 which are located below (II)) do not interfere with the second mating connector 3, that is, the movement of the movable member 83 also causes the movement of the coil spring 82. The fitting of the second mating connector 3 is allowed without accompanying compression. At that time, the upper surface of the movable member 83 functions as the restricting portion 83B to guide the fitting while restricting the lower surface of the second mating connector 3.
