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 the plurality of conductors of the circuit board 101, and come into contact with the plurality of contacts 7 (described later) of the plug connector 3 when fitted. 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.

As shown in FIG. 10, each of the six contacts 4 has a connecting portion 41 and a contact portion 42. As shown in FIG. 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 contact 7 (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 contact 4 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 contact 4 is formed by punching out a single plate from a thin metal plate and subjecting it to bending or the like. Note that the connecting portion 41 may have any shape as long as it can be attached to the circuit board 101, and may have a shape that does not protrude outward.

As shown in FIGS. 2 and 4, the contact holding section 5 is an insulating member that holds a plurality of contacts 4. As shown in FIGS. 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.

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.

As shown in FIG. 2, 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.

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.

This makes it possible to visually confirm the connection state of the connection portion 41 to the circuit board 101.

The shell 6 is a conductive member attached to the contact holding part 5, as shown in FIG. As shown in FIG. 4, the shell 6 has at least one partition wall 61 that partitions the contact holding part 5 into the plurality of holding areas. The partition wall 61 is electrically connected to a ground conductor (not shown) of the circuit board 101. The partition wall 61 may be directly connected to the ground conductor of the circuit board 101, or may be connected to the ground conductor of the circuit board 101 via another portion of the shell 6. The shell 6 may include two partition walls 61 doubly interposed between the two second type holding areas 52A and 52B.

There is. Further, as shown in FIG. 6, the connecting portion 71 protrudes 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.

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.

As shown in FIG. 6, each of the second type holding areas 92A and 92B has one holding protuberance 921. The holding raised portion 921 is formed on the front surface 95 of the main body portion 94 and protrudes toward the receptacle connector 2 from the base along the long side direction DL1. In the short side direction DS1, the holding protrusion 921 is located between the long side 8a and the long side 8b.

The holding raised portion 921 of the second type holding area 92A is separated from the holding raised portions 911A and 911B of the first type holding area 91 by a gap S21 along the boundary PL21. The holding raised portion 921 of the second type holding area 92B is separated from the holding raised portions 911A and 911B of the first type holding area 91 by a gap S22 along the boundary PL22. One second type contact 7B held by each of the second type holding areas 92A and 92B is arranged on the holding raised portion 921.

The second type contact 7B arranged on the holding raised part 921 has the apex (the most protruding part) of the contact part 72 and its surroundings like the first type contact 7A arranged on the holding raised part 911B. It is attached to the holding raised part 921 so as to be exposed on the side surface of the raised part 921. Thereby, the second type contact 7B disposed on the holding raised portion 921 is also disposed such that the connection direction between the connecting portion 71 and the contact portion 72 is along the short side direction DS1.

Furthermore, the connection portion 71 of the second type contact 7B in the second type holding area 92B protrudes from the end of the contact portion 72 toward the long side 8b. The connecting portion 71 is exposed between the main body portion 94 and the long side 8b when viewed from the receptacle connector 2. Thereby, it is possible to visually confirm the connection state of the connection portion 71 to the circuit board 102 even in the second type holding area 92B.

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, as shown in FIGS. 7 and 9, 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, and two ground connection portions 825 on the side wall 82B.

The shell member 80E has a side wall 83A along the long side 8a, a side wall 83B along the long side 8b, and a side wall 82A along the short side 8c around the second type holding area 92A. The shell member 80E also has a partition wall 87A extending from the end of the side wall 83B near the first type holding area 91 and partitioning the second type holding area 92A and the first type holding area 91. The shell member 80F has a side wall 83A along the long side 8a, a side wall 83B along the long side 8b, and a side wall 82B along the short side 8d around the second type holding area 92B. The shell member 80F also has a partition wall 87B extending from the end of the side wall 83A near the first type holding area 91 and partitioning the second type holding area 92B and the first type holding area 91.

The partition walls 87A and 87B described above can function as partition walls that partition the first type holding area 51 and the second type holding areas 52A and 52B when the plug connector 3B is fitted to the receptacle connector. Further, the side walls 83A, 83B, and 82A of the shell member 80E function as a surrounding wall surrounding the outer periphery of the second type holding area 52A when the plug connector 3B is fitted to the receptacle connector. Similarly, the side walls 83A, 83B, and 82B of the shell member 80F function as a surrounding wall surrounding the outer periphery of the second type holding area 52B when the plug connector 3B is fitted to the receptacle connector. In this way, the plug connector 3B has a partition wall that partitions the first type holding area 51 and the second type holding areas 52A, 52B and the second type holding areas 52A, 52B when mated with the receptacle connector. It has a shape including a surrounding wall surrounding the outer periphery.

A plug connector 3C shown in FIG. 18 is an example of a connector that is not provided with any structures corresponding to surrounding walls and partition walls. Similar to the plug connector 3, the plug connector 3C is provided with a plurality of first type contacts 7A in the first type holding area 91, and one second type contact 7B in each of the second type holding areas 92A and 92B. is provided. However, since the plug connector 3C does not have a configuration equivalent to a shell, it has a configuration equivalent to a partition wall that partitions these areas or a surrounding wall that surrounds the outer periphery of the second type holding areas 92A and 92B. I haven't.

By appropriately changing the combinations of the various receptacle connectors 2, 2A to 2D and plug connectors 3, 3A to 3C described above, it is possible to achieve a It is possible to realize a connector device including a partition wall that partitions the first type holding area 51 and the second type holding areas 52A, 52B, and a surrounding wall surrounding the outer periphery of the second type holding areas 52A, 52B. . Furthermore, depending on the combination, it is possible to realize a connector device that further includes a second surrounding wall provided along the outer periphery of the first type holding area 51.

Specifically, by using the combinations shown in Table 1, the partition wall that partitions the first type holding area 51 and the second type holding areas 52A, 52B when they are fitted together, and the second type holding area 52A , 52B can be realized.

Among the above combinations, when the receptacle connector 2A or the plug connector 3C is used, the other connector is provided with both the surrounding wall and the partition wall. In this way, the partition wall and the surrounding wall may be attached to either the first connector or the second connector. In such a combination, since the partition wall and surrounding wall are placed on one connector, the other connector, which is not provided with the partition wall and surrounding wall, can have a simple configuration and can be easily handled. can do.

Note that Table 1 shows the combination of the receptacle connectors 2, 2A to 2D and the plug connectors 3, 3A to 3C described above, and is not limited to the above combination.

Note that depending on the combination of a receptacle connector and a plug connector, the shapes of the receptacle connectors 2, 2A to 2D and the plug connectors 3, 3A to 3C may be changed in order to fit them appropriately.
