Hereinafter, the direction along the long sides of this rectangle will be referred to as long side direction DL1, and the direction along the short sides of this rectangle will be referred to as short side direction DS1. Further, the direction perpendicular to this rectangle is referred to as the connection direction CD1 of the receptacle connector 2 and the plug connector 3. Hereinafter, when describing the structure of the plug connector 3 seen from the receptacle connector 2 in a state where the receptacle connector 2 and the plug connector 3 are arranged so as to fit into each other, it will be simply "as seen from the receptacle connector 2". When describing the structure of the receptacle connector 2 seen from the plug connector 3, it is simply referred to as "as seen from the plug connector 3."

[Receptacle connector]
First, the configuration of the receptacle connector 2 will be explained in detail. As described above, the receptacle connector 2 is attached to the circuit board 101 and connected to the plug connector 3, which is a mating connector. As shown in FIGS. 2 to 4, the receptacle connector 2 includes a plurality of conductive contacts 4, a contact holding portion 5, and a shell 6.

The plurality of contacts 4 are respectively connected to a plurality of conductors of the circuit board 101 and come into contact with a plurality of contacts 7 (described later) of the plug connector 3, respectively. The plurality of contacts 4 may include contacts 4 of different types. For example, the plurality of contacts 4 include a plurality of first type contacts 4A and at least one second type contact 4B of a different type from the first type contacts 4A. As an example, the receptacle connector 2 includes six contacts 4, and the six contacts 4 include four first type contacts 4A and two second type contacts 4B.

Being of different types means that they belong to different types under some definition that specifies the difference between the types. Specific examples of differences in type include differences in the frequency band of the signal to be transmitted, differences in allowable current, differences in allowable voltage, and whether it is for connection of a signal conductor (a conductor that forms part of a signal circuit) or ground. Differences include whether the connection is for a conductor (a conductor that forms part of a ground circuit). As an example, the second type contact 4B is a contact that transmits a higher frequency signal than the signal transmitted by the first type contact 4A. In the connector device 1 of this embodiment, the first type contacts 4A and the second type contacts 4B also have different shapes.

The first type contact 4A has a connection part 41 and a contact part 42, as shown in FIGS. 2 and 4. The connecting portion 41 is connected to a conductor (for example, a signal conductor) of the circuit board 101. The contact portion 42 contacts a first type contact 7A (described later) of the plug connector 3. The connecting portion 41 and the contact portion 42 are connected to each other. The contact portion 42 of the first type contact 4A is approximately U-shaped, and both ends of the contact portion 42 protrude toward the plug connector 3 along the connection direction CD1, and sandwich the contact 7 of the plug connector 3. Further, the connecting portion 41 protrudes outward from one end of the substantially U-shaped contact portion 42 in a direction opposite to the contact portion 42 .

The second type contact 4B has a connection part 43 and a contact part 44, as shown in FIGS. 3 and 4. The contact portion 44 contacts a second type contact 7B (described later) of the plug connector 3. The connecting portion 43 and the contact portion 44 are connected to each other. The contact portion 44 of the second type contact 4B has a substantially cylindrical shape with an axis along the connection direction CD1, and one end that is not connected to the connection portion 43 protrudes toward the plug connector 3 in the axial direction. A second type contact 7B (described later) of the plug connector 3 enters the central opening 441 of the contact portion 44. Further, the connecting portion 43 projects outward from the other end of the contact portion 44 in the axial direction.

These contacts 4 are formed by punching out a single plate from a thin metal plate and subjecting it to bending or the like. Note that the connecting portions 41 and 43 may have any shape as long as they can be attached to the circuit board 101, and may have a shape that does not protrude outward.

The contact holding section 5 is an insulating member that holds a plurality of contacts 4. For example, the contact holding portion 5 is formed by injection molding of a resin material. The contact holding portion 5 has a back surface 55 facing the circuit board 101 and a front surface 54 facing opposite to the back surface 55. The contact holding portion 5 has an outer shape that approximates a rectangle when viewed from the plug connector 3. The rectangle has a pair of long sides 5a and 5b along the long side direction DL1 and a pair of short sides 5c and 5d along the short side direction DS1.

As shown in FIG. 2, the contact holding section 5 is divided into a plurality of holding areas in a direction perpendicular to the connection direction CD1. The plurality of holding areas include a first type holding area 51 and a second type holding area 52. The first type holding area 51 holds a plurality of contacts 4. For example, the first type holding area 51 holds a plurality (for example, four) of first type contacts 4A. The second type holding area 52 holds one contact 4 and does not hold other contacts 4. For example, the second type holding area 52 holds one second type contact 4B.

The plurality of holding areas may include two second type holding areas 52, and at least one first type holding area 51 may be interposed between the plurality of second type holding areas 52. As an example, the contact holding section 5 is divided into one first type holding area 51 and two second type holding areas 52 sandwiching the first type holding area 51. The first type holding area 51 and the two second type holding areas 52 are lined up along the long side direction DL1. Hereinafter, the two second type holding areas 52 will be distinguished as second type holding areas 52A and 52B.

The plurality of holding areas may be divided by gaps formed in the contact holding part 5. For example, the second type holding area 52A and the first type holding area 51 are separated by a gap S11 along a boundary PL11 perpendicular to the long side direction DL1. As an example, the second type holding area 52A and the first type holding area 51 are separated by a slit 53A perpendicular to the long side direction DL1.

The first type holding area 51 and the second type holding area 52B are separated by a gap S12 along a boundary PL12 perpendicular to the long side direction DL1. As an example, the first type holding area 51 and the second type holding area 52B are separated by a slit 53B perpendicular to the long side direction DL1.

Note that the gap here does not necessarily mean the gap in the completed state of the receptacle connector 2, but refers to the gap when the contact holding part 5 exists alone. That is, the void here also includes a portion that is filled with a member different from the contact holding portion 5 when the receptacle connector 2 is completed. For example, at least a portion of the gap S11 is filled with a partition wall 61A described below, and at least a portion of the gap S12 is filled with a partition wall 61B described below.

In the contact holding portion 5, all contacts 4 have the same connection direction between the connection portion 41 and the contact portion 42 (the direction in which the connection portion 41 and the contact portion 42 connected to each other are lined up) when viewed from the connection direction CD1. are arranged along the direction of In other words, all the contacts 4 are arranged so that the direction of contact between the contact portion 42 and the contact 7 of the plug connector 3 is along the same direction. For example, each of the contacts 4 is arranged such that the direction in which the connection portion 41 and the contact portion 42 are connected is along the short side direction DS1. When viewed from the plug connector 3, the contact portions 42 of all the contacts 4 are arranged inward from the outer edge of the contact holding portion 5.

As shown in FIG. 3, the first type holding area 51 has accommodation grooves extending in the same direction (for example, long side direction DL1). In the first type holding area 51, the contact portions 42 of all the first type contacts 4A are arranged so as to be exposed to the receiving groove portion. A holding protrusion (described later) of the plug connector 3 is accommodated in the accommodation groove. The first type contact 4A arranged in the accommodation groove is arranged so that the contact part 42 contacts a contact part 72 (described later) of the contact 7 of the holding raised part accommodated in the accommodation groove.

As an example, the first type holding area 51 has two accommodation grooves 511A and 511B that are parallel to each other. The accommodation grooves 511A and 511B are formed on the front surface 54 of the contact holding section 5 along the long side direction DL1, respectively.

That is, the plurality of first type contacts 4A held by the first type holding area 51 include the plurality of first type contacts 4A lined up along the long side direction DL1 (the arrangement direction perpendicular to the boundaries PL11 and PL12). As shown in FIG. 4, two contact accommodating parts 512A and 512B, each of which is a through hole extending in the connection direction CD1, are provided in the accommodating grooves 511A and 511B. The contact accommodating portions 512A, 512B are holes provided so as to penetrate from the back surface 55 to the front surface 54 of each contact holding portion 5, and are open to the accommodating groove portions 511A, 511B. The first type contact 4A is fixed to each of the contact housing parts 512A and 512B by press-fitting or the like so that both ends of the U-shaped contact part 42 are exposed in the housing groove parts 511A and 511B. As a result, all of the first type contacts 4A lined up along the accommodation grooves 511A and 511B are arranged such that the connection direction between the connection part 41 and the contact part 42 when viewed from the connection direction CD1 is along the short side direction DS1. ing.

As shown in FIG. 3, in the connection direction CD1, the inter-area connection plates 64A, 64B have an edge 641 facing the circuit board 101. The inter-area connection plates 64A, 64B are electrically connected to the ground conductor of the circuit board 101 at the edge 641. The inter-area connection plates 64A and 64B have elastic portions 643 whose tips protrude outward (in a direction opposite to the direction toward the first type holding area 51). For example, the inter-area connection plates 64A and 64B have an elastic portion 643 between two protrusions 626.

Since the shell 6 has the inter-area connection plates 64A, 64B, the first type holding area 51 is surrounded by the partition walls 61A, 61B and the inter-area connection plates 64A, 64B. Further, the entire contact holding portion 5 is surrounded by surrounding walls 62A, 62B and inter-area connection plates 64A, 64B.

The shell 6 is formed, for example, by punching out a sheet of metal from a thin sheet material and subjecting it to bending or the like. For example, in the plate material, areas corresponding to the partition walls 61A, 61B, surrounding walls 62A, 62B, and inter-area connection plates 64A, 64B are moved approximately in the same direction with respect to areas corresponding to the intra-area connection plates 63A, 63B. By bending 90 degrees, the shell 6 is formed. The formed shell 6 is attached to the contact holding part 5 by, for example, press fitting.

The receptacle connector 2 configured as described above is attached to the circuit board 101 with the back surface 55 facing the circuit board 101. At this time, with respect to the ground conductor exposed on the surface of the circuit board 101, the edge 611 of the partition wall 61A, the edge 611 of the partition wall 61B, the edges 625, 627, 627 of the surrounding wall 62A, and the surrounding Edges 625, 627, and 627 of the wall 62B, an edge 641 of the inter-area connection plate 64A, and an edge 641 of the inter-area connection plate 64B are respectively connected by soldering or the like. Furthermore, the connection portions 41 of the four first type contacts 4A and the connection portions 43 of the two second type contacts 4B are connected to each of the plurality of regions where the signal conductors formed on the circuit board 101 are exposed. For example, they are connected by soldering or the like.

Note that the above configuration is just an example and can be modified as appropriate. For example, the contact holding section 5 only needs to have at least one second type holding area 52, and does not necessarily need to have two or more second type holding areas 52. The contact holding section 5 may be divided into four or more holding areas. The first type holding area 51 does not necessarily need to be interposed between the two second type holding areas 52, and the second type holding areas 52 may be adjacent to each other. Even in such a case, two partition walls 61A and 61B may be doubly interposed between the second type holding areas 52.

Further, when the receptacle connector 2 and the plug connector 3 are fitted together, the second type contacts 4B (described later) of the receptacle connector 2 hold the periphery of the contact portion 74. Further, the connecting portion 73 projects outward from the other end of the contact portion 74 (the end not facing the receptacle connector 2) in the axial direction.

The first type contact 7A and the second type contact 7B are formed by punching out a single plate from a thin metal plate and subjecting it to bending or the like. Note that the connecting portions 71 and 73 may have any shape as long as they can be attached to the circuit board 102, and may have a shape that does not protrude outward.

The shell 8 is a conductive member surrounding the plurality of contacts 7 . The shell 8 surrounds an area having an approximately rectangular shape when viewed from the receptacle connector 2 . The rectangle has a pair of long sides 8a and 8b along the long side direction DL1 and a pair of short sides 8c and 8d along the short side direction DS1. The shell 8 has a side wall 81A along the long side 8a, a side wall 81B along the long side 8b, a side wall 82A along the short side 8c, and a side wall 82B along the short side 8d.

Similarly, the side wall 81B also has two recesses 811 on its inner surface (the surface facing the side wall 81A). The two recesses 811 engage with the protrusions 626 of the surrounding wall 62A and the surrounding wall 62B, respectively.

In the connection direction CD1, each of the side walls 81A and 81B has an edge 813 facing the circuit board 102 and at least one ground connection portion 815 that protrudes from the edge 813 and contacts the circuit board 102, as shown in FIG. and has. For example, each of the side walls 81A and 81B has three ground connection portions 815 lined up along the long side direction DL1. Each of the side walls 81A and 81B is electrically connected to the ground conductor of the circuit board 102 at a ground connection portion 815.

The side wall 82A has two recesses 821 on its inner surface (the surface facing the side wall 82B). The two recesses 821 engage with the two protrusions 624 of the surrounding wall 62A, respectively. Similarly, the side wall 82B also has two recesses 821 (not shown) on its inner surface (the surface facing the side wall 82A).

Each of the side walls 82A and 82B is electrically connected to the ground conductor of the circuit board 102 at a ground connection portion 825.

As shown in FIG. 6 etc., the shell 8 has an intermediate portion in the short side direction DS1 of the side wall 82A (for example, between two ground connection portions 825) and an intermediate portion in the short side direction DS1 of the side wall 82B (for example, in two places). (between the ground connection portions 825) into two shell members 80A and 80B arranged in the short side direction DS1. The shell member 80A includes the side wall 81A, and the shell member 80B includes the side wall 81B.

Each of the shell members 80A and 80B is formed, for example, by punching out a sheet of metal from a thin sheet material and subjecting it to bending or the like. By dividing the shell 8 into two members in this manner, processing is facilitated.

The wall member 11 is a member disposed continuously on the shell 8. As shown in FIGS. 8(a) and 8(b), the wall member 11 is approximately U-shaped in plan view, and includes a pair of opposing partition walls 111A and 111B, and a pair of partition walls 111. It has a connection wall 112 that connects the one ends. The plug connector 3 is provided with two wall members 11A and 11B.

The partition walls 111A and 111B have the same rectangular shape and extend in parallel. Furthermore, a protrusion 113 for connecting to the shell 8 is provided at each end of the partition walls 111A and 111B. The protrusions 113 of the partition wall 111A and the protrusions 113 of the partition wall 111B are provided to face each other as shown in FIG. 8(a). Moreover, the protrusion part 113 may be provided so that it may protrude from the edge part of the partition wall 111A, 111B along the extending direction of the partition wall 111A, 111B. Further, the tip 113a of the protrusion 113 may protrude further downward (in the direction toward the circuit board 102) than the partition walls 111A and 111B along the connection direction CD1. Further, the tip 113a may be configured to be directly connected to the ground conductor of the circuit board 102.

The connection wall 112 connects the opposite ends of the partition walls 111A and 111B arranged in parallel to the end where the protrusion 113 is provided. That is, the connection wall 112 extends in a direction perpendicular to the extending direction of the partition walls 111A and 111B. The partition walls 111A, 111B and the connection wall 112 are arranged to form three sides of a quadrilateral in plan view. Note that the connection wall 112 is provided with a ground connection portion 114 that protrudes toward the circuit board 102 in the same manner as the tip 113a of the protrusion 113 along the connection direction CD1 with the circuit board 102. The ground connection portions 114 are provided at both ends of the connection wall 112, that is, at positions close to the partition walls 111A and 111B. The wall member 11 may be provided with a cutout or the like to improve adhesion to the contact holding portion 9. For example, a pair of notches 115 are provided at the boundary between the partition walls 111A, 111B and the connection wall 112. The pair of notches 115 are provided to allow the partition wall 61 of the receptacle connector 2 to enter when the plug connector 3 and the receptacle connector 2 are fitted together. This point will be discussed later. Further, the ground connection portion 114 has a curved shape as shown in FIG. 8(b).

The wall member 11 is formed, for example, by punching out a sheet of metal from a thin sheet material and subjecting it to bending or the like.

As shown in FIG. 5, the plug connector 3 uses two wall members 11A and 11B. The wall members 11A and 11B are each arranged so as to surround one second type contact 7B in a plan view. For example, the wall member 11A is arranged such that the side wall 82A of the shell 8 and the connection wall 112 face each other with the second type contact 7B closest to the side wall 82A interposed therebetween. Further, the connection wall 112 of the wall member 11A is arranged between the second type contact 7B and the first type contact 7A (including the two first type contacts 7A closer to the side wall 82A). At this time, the partition wall 111A is arranged between the side wall 81A and the second type contact 7B (the second type contact 7B located between the side wall 82A and the connection wall 112), and the partition wall 111B is arranged between the side wall 81B and the second type contact 7B. It is arranged between the seed contact 7B (the second type contact 7B located between the side wall 82A and the connection wall 112). At this time, the protrusion 113 comes into contact with the side wall 82A.

Further, for example, the wall member 11B is arranged such that the side wall 82B of the shell 8 and the connection wall 112 face each other with the second type contact 7B closest to the side wall 82B interposed therebetween. Further, the connection wall 112 of the wall member 11B is arranged between the second type contact 7B and the first type contact 7A (of which two first type contacts 7A near the side wall 82B). At this time, the partition wall 111A is arranged between the side wall 81B and the second type contact 7B (the second type contact 7B located between the side wall 82B and the connection wall 112), and the partition wall 111B is arranged between the side wall 81A and the second type contact 7B. It is arranged between the seed contact 7B (the second type contact 7B located between the side wall 82B and the connection wall 112). At this time, the protrusion 113 comes into contact with the side wall 82B.

The contact holding section 9 is an insulating member that holds the plurality of contacts 7, the shell 8, and the wall member 11. For example, the contact holding portion 9 is formed by insert molding with a plurality of contacts 7, shells 8, and wall members 11 arranged in a mold.

The contact holding section 9 has a frame section 93 and a main body section 94. The frame portion 93 holds at least a portion of the shell 8 (for example, the side walls 82A, 82B) from the outer periphery. The main body portion 94 is disposed between the side walls 82A and 82B, and is connected to the frame portion 93. As shown in FIGS. 5 and 7, the main body portion 94 has a back surface 96 facing the circuit board 102 and a front surface 95 facing oppositely to the back surface 96. The main body portion 94 is divided into a plurality of holding areas in a direction perpendicular to the connection direction CD1.

The plurality of holding areas include a first type holding area 91 and a second type holding area 92. The first type holding area 91 holds a plurality of contacts 7 . For example, the first type holding area 91 holds a plurality (for example, four) of first type contacts 7A. The second type holding area 92 holds one contact 7 and does not hold other contacts 7. For example, the second type holding area 92 holds one second type contact 7B.

The plurality of holding areas may include two second type holding areas 92, and at least one first type holding area 91 may be interposed between the plurality of second type holding areas 92. As an example, the main body portion 94 is divided into one first type holding area 91 and two second type holding areas 92 sandwiching the first type holding area 91. The first type holding area 91 and the two second type holding areas 92 are lined up along the long side direction DL1. Hereinafter, the two second type holding areas 92 will be distinguished as second type holding areas 92A and 92B.

When the main body portion 94 is divided into one first type holding area 91 and two second type holding areas 92A, 92B sandwiching the first type holding area 91, the side walls 81A, 81B, 82A, 82B is provided so as to surround the outer periphery of each area. In other words, the side walls 81A, 81B, 82A, 82B of the shell 8 can function as a surrounding wall surrounding the first type holding area 91 and the second type holding area 92A, 92B.

The plurality of holding areas may be partitioned by wall members 11, for example. For example, between the second type holding area 92A and the first type holding area 91, as shown in FIG. 5, a connecting wall 112 of the wall member 11A is provided along a boundary PL21 perpendicular to the long side direction DL1, It is divided by a connecting wall 112. The first type holding area 91 and the second type holding area 92B are partitioned by a connecting wall 112 of the wall member 11B provided along a boundary PL22 perpendicular to the long side direction DL1. That is, the connection wall 112 of the wall member 11 can function as a partition wall that partitions the first type holding area 91 and the second type holding area 92 (92A or 92B).

Note that a groove 117A formed by a pair of notches 115 (see FIG. 8(a)) is formed along the connection wall 112 of the wall member 11A. The groove portion 117A extends along the short side direction DS1 similarly to the connection wall 112. Further, a groove portion 117B formed by a pair of notches 115 is also formed in the connecting wall 112 of the wall member 11B. The groove portion 117B extends along the short side direction DS1 similarly to the connection wall 112. With the partition walls 61 of the receptacle connector 2 inserted into the grooves 117A and 117B, the receptacle connector 2 and the plug connector 3 are fitted together.

In the contact holding part 9, for all the first type contacts 7A, the connection direction of the connection part 71 and the contact part 72 (the direction in which the connection part 71 and the contact part 72 that are connected to each other are lined up) when seen from the connection direction CD1 ) are arranged along the same direction. In other words, all the contacts 7 are arranged so that the direction of contact between the contact portion 72 and the contact 4 of the receptacle connector 2 is along the same direction. For example, each of the contact parts 72 is arranged such that the connection direction between the connection part 71 and the contact part 72 is along the short side direction DS1. When viewed from the receptacle connector 2, the contact portions 72 of all the first type contacts 7A are arranged inward from the outer edge of the contact holding portion 9.

Further, for both of the two type 2 contacts 7B, the connecting direction of the connecting portion 73 and the contact portion 74 (the direction in which the connecting portion 73 and the contact portion 74 that are connected to each other are lined up) is the same when viewed from the connecting direction CD1. are arranged along the direction of Further, when viewed from the receptacle connector 2, the contact portions 74 of the two second type contacts 7B are arranged inward from the outer edge of the contact holding portion 9.

Further, the first type holding area 91 has a holding protuberance that protrudes toward the receptacle connector 2 from the base along the same direction (for example, the long side direction DL1). In the first type holding area 91, the contact portions 72 of all the first type contacts 7A are exposed on the side surface of the holding raised portion. As an example, the first type holding area 91 has two holding protrusions 911A and 911B that are parallel to each other. The holding raised parts 911A and 911B are formed on the front surface 95 of the main body part 94, and protrude toward the receptacle connector 2 from the base along the long side direction DL1. On the front surface 95, the holding protrusion 911A is located near the long side 8a of the shell 8, and the holding protrusion 911B is located near the long side 8b of the shell 8.

The four first type contacts 7A held by the first type holding area 91 are two first type contacts 7A lined up along the holding raised part 911A, and two first type contacts 7A lined up along the holding raised part 911B. contact 7A. That is, the plurality of first type contacts 7A held by the first type holding area 91 include the plurality of first type contacts 7A lined up along the long side direction DL1 (the arrangement direction perpendicular to the boundaries PL21 and PL22).

All of the first type contacts 7A lined up along the holding raised part 911A are arranged so that the apex (the most protruding part) of the contact part 72 and its surroundings are exposed on the side surface of the held raised part 911A. will be installed on the As a result, all of the first type contacts 7A lined up along the holding raised portion 911A are arranged such that the connection direction between the connection portion 71 and the contact portion 72 is along the short side direction DS1 when viewed from the connection direction CD1. There is. Furthermore, the connecting portion 71 extends from the end of the contact portion 72 toward the long side 8a. In the first type contact 7A of the holding raised portion 911A, the connecting portion 71 is exposed between the main body portion 94 and the long side 8a when viewed from the receptacle connector 2. This allows visual confirmation of the connection state of the connection portion 71 to the circuit board 102.

Similarly, any of the first type contacts 7A lined up along the holding protrusion 911B are arranged so that the apex (the most protruding part) of the contact part 72 and its surroundings are exposed on the side surface of the holding protrusion 911B. It is attached to the raised portion 911B. As a result, all of the first type contacts 7A lined up along the holding raised portion 911B are arranged such that the connection direction between the connection portion 71 and the contact portion 72 is along the short side direction DS1 when viewed from the connection direction CD1. There is. The connecting portion 71 extends from the end of the contact portion 72 toward the long side 8b. In the first type contact 7A of the holding raised portion 911B, the connecting portion 71 is exposed between the main body portion 94 and the long side 8b when viewed from the receptacle connector 2. This allows visual confirmation of the connection state of the connection portion 71 to the circuit board 102.

When the plug connector 3 is fitted into the receptacle connector 2, the holding protrusion 911A is accommodated in the accommodation groove 511A, and the holding protrusion 911B is accommodated in the accommodation groove 511B). In both of the holding raised portions 911A and 911B, the contact portion 72 of the first type contact 7A contacts the contact portion 42 of the first type contact 4A.

A flat surface 97 is formed around the second type contact 7B so that the periphery of the contact portion 74 is exposed. This is because the contact portion 74 has a shape that allows it to enter the opening 441 of the contact portion 44 of the second type contact 4B when the plug connector 3 is fitted into the receptacle connector 2. However, the flat surface 97 is provided with a recess 971 that penetrates from the front surface 95 to the rear surface 96 along the connection direction CD1. The recessed portion 971 is formed at a position corresponding to the connecting portion 41 of the second type contact 4B when viewed from the connecting direction CD1. In the second type contact 7B, the end of the connecting portion 73 that extends toward the long side 8a or 8b with respect to the contact portion 74 is located in a region surrounded by the recess 971 and the partition wall 111A. This allows visual confirmation of the connection state of the connection portion 73 to the circuit board 102.

The plug connector 3 configured as described above is attached to the circuit board 102 with the back surface 96 facing the circuit board 102. For example, three ground connection portions 815 on the side wall 81A, three ground connection portions 815 on the side wall 81B, two ground connection portions 825 on the side wall 82A, two ground connection portions 825 on the side wall 82B, and three ground connection portions 815 on the side wall 81B. The two ground connection portions 114 and the two ground connection portions 114 of the wall member 11B are respectively connected to the exposed area of the ground conductor formed on the circuit board 102 by soldering or the like. Furthermore, the connection portions 71 of the four first type contacts 7A and the connection portions 73 of the two second type contacts 7B are connected to each of the plurality of regions where the signal conductors formed on the circuit board 102 are exposed. For example, they are connected by soldering or the like.

As an example, when the plug connector 3 is mated to the receptacle connector 2, the second type holding areas 92A and 92B of the plug connector 3 are opposed to the second type holding areas 52A and 52B of the receptacle connector 2, respectively. Suppose that they are mated. At this time, as described above, the shell 8 is located on the outer periphery of the shell 6 (see also FIG. 12).

In this state, as shown in FIGS. 12 and 13, the side wall 81A contacts the side portion 622A of the surrounding wall 62A, the side portion 622A of the surrounding wall 62B, and the inter-area connection plate 64A.

At this time, the elastic portion 613 provided on the partition wall 61B presses the connection wall 112.

Note that the above configuration is just an example and can be modified as appropriate. For example, the contact holding section 9 only needs to have at least one second type holding area 92, and does not necessarily need to have two or more second type holding areas 92. The contact holding section 9 may be divided into four or more holding areas. The first type holding area 91 does not necessarily need to be interposed between the two second type holding areas 92, and the second type holding areas 92 may be adjacent to each other.

Furthermore, when the receptacle connector 2 and the plug connector 3 are mated together, a first partition wall and a second partition wall are arranged in a double manner between the first type holding area 51 and the second type holding area 52. be done. Specifically, between the first type holding area 51 and the second type holding area 52A, a partition wall 61A and a connecting wall 112 are arranged in a double manner, and the first type holding area 51 and the second type holding area 52B, a partition wall 61B and a connecting wall 112 are arranged doubly. Further, on the outer periphery of the second type holding area 52, a first surrounding wall and a second surrounding wall are arranged doubly. Specifically, side walls 81A, 81B, 82A and an enclosing wall 62A are arranged doubly on the outer periphery of the second type holding area 52A, and side walls 81A, 81B, 82B are arranged on the outer periphery of the second type holding area 52B. And the surrounding wall 62A is arranged in double.

According to the above-mentioned connector device 1, when the receptacle connector 2 (first connector) and the plug connector 3 (second connector) are mated, there is a gap between the second type holding area 52 and the first type holding area 51. , the first partition wall and the second partition wall are arranged in a double layer, and the first surrounding wall and the second surrounding wall are arranged in a double layer on the outer periphery of the second type holding area 52. Therefore, noise can be effectively suppressed, especially for contacts arranged in the second type holding area 52 that are likely to become a noise source.

Furthermore, in the connector device 1 described above, when the receptacle connector 2 and the plug connector 3 are fitted together, the partition walls 61A and 61B as the first partition walls and the connection wall 112 as the second partition wall, respectively. Contact. With such a configuration, the first partition wall and the second partition wall can be at the same potential, and noise can be suppressed more reliably.

Further, either the first partition wall or the second partition wall has an elastic portion that presses the other partition wall when they come into contact. Specifically, in the connector device 1, the partition walls 61A and 61B have elastic portions 613, and press the mating connection wall 112. In this way, by having a configuration in which the elastic portion presses and supports the other partition wall, contact between the two can be made more reliably.

Moreover, in the above connector device 1, when the receptacle connector 2 and the plug connector 3 are fitted, the surrounding walls 62A, 62B as the first surrounding walls and the side walls 81A, 81B, 82A, 82B as the second surrounding walls come into contact with. With such a configuration, the first surrounding wall and the second surrounding wall can be at the same potential, and noise can be suppressed more reliably.

Each of the contacts 4 and 7 needs to be provided with a connection part to the circuit board, but generally the connection part can be provided outward from the contact part for connecting with the other contact. In this case, if the connection portion is close to another contact, the noise suppression effect may be reduced. On the other hand, with the above configuration, it is possible to ensure a large distance from the contacts particularly arranged in the second type holding area 52 (92).

Note that the connection portion 73 as a substrate connection portion of the contact 7 arranged in the second type holding area 52 (second type holding area 92) may face the partition wall 111A or the partition wall 111B as a contact surrounding wall. .
