In the connector 11, the arrangement direction of the first contact portions 21A, 22A, and 23A of the first contact sub-members 21, 22, and 23 constituting the one end portions 121A, 122A, and 123A of the signal contacts 121, 122, and 123, and The arrangement directions of the third contact portions 41C, 42C, and 43C of the third contact sub-members 41, 42, and 43 constituting the other end portions of the signal contacts 121, 122, and 123 are different from each other. Therefore, even if the first contact portions 21A, 22A, and 23A of the first contact sub-members 21, 22, and 23 are arranged in accordance with, for example, an arrangement pattern determined by specifications, etc., the third contact sub-members 41, 42 and 23 can be freely arranged. The third contact portions 41C, 42C, and 43C of 43 can improve the degree of freedom of the arrangement pattern of the third contact portions 41C, 42C, and 43C. As a result, the connector 11 can be easily and automatically assembled to the wiring object M by using a robot or the like.

In the above-described embodiment, the third contact portions 41C, 42C, and 43C of the third contact sub-members 41, 42, and 43 having the elastic piece 45 are connected to the first connection terminal 81, the first connection terminal 81, and the first connection object M having a flat plate shape. The second connection terminal 82 and the third connection terminal 83, but conversely, the third contact portions 41C, 42C, and 43C of the third contact sub-members 41, 42, and 43 may have a flat plate shape, and the first The connection terminal 81 , the second connection terminal 82 and the third connection terminal 83 have elastic pieces.

However, if the first connection terminal 81 , the second connection terminal 82 , and the third connection terminal 83 of the wiring object M have elastic pieces, if the wiring object M is used in a dusty environment, the generated dust will adhere to the elastic pieces. It is difficult to remove dust by the elastic sheet, and the reliability of the electrical connection with the connector 11 may be impaired. If the 1st connection terminal 81, the 2nd connection terminal 82, and the 3rd connection terminal 83 have a flat shape, the removal of dust becomes easy. Therefore, as shown in the above-mentioned embodiment, it is preferable that the elastic pieces 45 are provided in the third contact portions 41C, 42C and 43C of the third contact sub-members 41 , 42 and 43 .

Wherein, in the above-mentioned embodiment, the second connecting portions 31A, 32A and 33A of the second contact sub-members 31, 32 and 33 respectively have two pairs of elastic pieces 35, but it is not limited to this, and one pair may also be provided. Elastic pieces 35 or three or more pairs of elastic pieces 35. However, in order to connect the first connection parts 21C, 22C, and 23C of the first contact sub-members 21, 22, and 23, which are formed of flat plate parts, and the second connection parts 31A, 32A of the second contact sub-members 31, 32, and 33, In order to improve the reliability of the electrical connection of 33A, the second connecting portions 31A, 32A and 33A preferably have two or more pairs of elastic pieces 35 .

In addition, in the above-mentioned embodiment, the first connecting portions 21C, 22C and 23C of the first contact sub-members 21, 22 and 23 formed by the flat plate portion are connected to the second contact sub-members 31, 32 and 33 and have elasticity. The second connecting parts 31A, 32A and 33A of the sheet 35, but also conversely, the second connecting parts 31A, 32A and 33A of the second contact sub-members 31, 32 and 33 have flat plate parts, the first contact sub-members 21, The first connecting portions 21C, 22C, and 23C of 22 and 23 have elastic pieces that sandwich the flat plate portion with both surfaces and are in elastic contact with the flat plate portion.

In the above-mentioned embodiment, two third contact sub-members 41, 42 and 43 are respectively connected to the second contact portions 31C, 32C and 33C of the second contact sub-members 31, 32 and 33, but this is not a limitation. In this case, one third contact sub-member 41, 42, and 43 may be connected to the second contact portions 31C, 32C, and 33C, respectively. However, in order to improve the reliability of the electrical connection between the second contact sub-members 31, 32, and 33 and the third contact sub-members 41, 42, and 43, two second contact portions 31C, 32C, and 33C are connected to each other. The third contact sub-members 41, 42 and 43 are preferred.

In the connector 11 of the embodiment, one pair or two pairs of elastic pieces may be formed on the second contact portions 31C, 32C, and 33C of the second contact sub-members 31, 32, and 33 to replace the flat plate portion, and the third contact portion is omitted. The members 41, 42, and 43 and the third housing 71 connect the second contact portions 31C, 32C, and 33C of the second contact sub-members 31, 32, and 33 to the first connection terminal 81 and the second connection terminal of the connection object M. 82 and the third connection terminal 83 . Even as described above, if the second contact sub-members 31, 32, and 33 are held so as to be movable in the XY plane, the second contact sub-members 31, 32, and 33 can absorb the positional shift, so that the The first contact sub-members 21 , 22 and 23 and the second contact sub-members 31 , 32 and 33 are surely conducted to the first connection terminal 81 , the second connection terminal 82 and the third connection terminal 83 of the connection object M.

However, since the second contact portions 31C, 32C and 33C of the second contact sub-members 31, 32 and 33 are formed of flat plate portions extending along the YZ plane, the third contact sub-members 41 and 42 shown in FIG. As shown in the elastic sheet 45 of and 43, if an elastic sheet that can be elastically deformed in the XZ plane is to be formed on the second contact portions 31C, 32C and 33C, the second contact portions 31C, 32C and 33C must be deformed to be along the The shape of the XZ plane derives the need to secure a large occupied space in the X direction. Therefore, in order to achieve the miniaturization of the connector 11, it is preferable to use the third contact sub-members 41, 42 and 43 and the third housing 71 as shown in the above-mentioned embodiment.

In the connector 11 of the above-mentioned embodiment, three signal contacts 121, 122 and 123 are used, but it is not limited to this, and the present invention can also be applied to two or more signal contacts sub connector. In addition, the signal contacts can also be used as power contacts.
