This structure enables protection of the communication lines from noise with the shield layer 49 and the insertion wall portion 84 in cooperation with each other.
The following is an explanation of a first modification of the embodiment.
The shield layer 49 is not limited to a plated layer, but may be, for example, a conductive metal plate or a conductive metal film. For example, the shield layer 49 may be a metal plate or a metal film fixed on at least one of the outer side surface 48d and the inner side surface 48e of the partition wall 48. The shield layer 49 may be disposed inside the partition wall 48, as illustrated in

In this case, the main member 40 is preferably provided with a partition wall separating the first holding portion 44 from the second holding portion 45. The shield layer 49 may be a plated layer formed on the partition wall of the main member 40, or a metal plate or a metal film fixed on the partition wall of the main member 40.
The position and/or the shape of the insertion wall portion 84 of the shield case 8 are not limited to the position and/or the shape illustrated in the embodiment described above. For example, the insertion wall portion 84 may be disposed located on substantially the same plane as that of the shield layer 49. The insertion wall portion 84 may be disposed so as to be located on substantially the same plane as one side surface of the shield member 9.
The following is an explanation of a second modification of the embodiment. The number of the first female terminals 51 and/or the number of the second female terminals 63 inserted into the female housing 4 are not limited to the numbers illustrated in the embodiment. In the connector structure 1, the male unit 3 is not limited to a substrate connector fixed on the substrate 100. For example, the connector structure 1 may be a structure connecting an electrical wire with an electrical wire. For example, the first male terminals 11 may be terminals connected to electrical wires for power supply. The second male terminals 12 may be terminals connected to a communication cable or the like.
The details disclosed in the embodiment and the modifications described above may be carried out in proper combinations.
The female housing of the connector structure according to the embodiment includes the first holding portion holding the first female terminals for power supply, the second holding portion formed as one unitary piece with the first holding portion and holding the second female terminals for communication, and the conductive shield layer separating the first holding portion from the second holding portion. The connector structure according to the embodiment produces the effect of suppressing reduction in communication quality with the conductive shield layer separating the first holding portion from the second holding portion.
