FIG. 5 is a side view showing a circuit board connection structure 100 using the multipolar connector set 1 of FIG. 1A.

The circuit board connection structure 100 includes a first connector 10 , a second connector 20 , a first circuit board 110 and a second circuit board 120 . In the second embodiment, first connector 10 is mounted on first circuit board 110 . The second connector 20 is mounted on the second circuit board 120 . The first internal terminal group 11A of the first connector 10 is electrically connected to the electrodes 111 of the first circuit board 110 via a conductive bonding material 40 such as solder. Similarly, the second internal terminal group 12A of the first connector 10 is electrically connected to the electrodes 112 of the first circuit board 110 via a conductive bonding material 40 such as solder. The third internal terminal group 21A of the second connector 20 is electrically connected to the electrodes 121 of the second circuit board 120 via a conductive bonding material 40 such as solder. Similarly, the fourth internal terminal group 22A of the second connector 20 is electrically connected to the electrodes 122 of the second circuit board 120 via a conductive bonding material 40 such as solder.

As shown in FIG. 5, the shield member 30 is electrically connected by contacting the electrodes 115 of the first circuit board 110 . When the first connector 10 and the second connector 20 are mated together, the shield member 30 contacts the first circuit board 110 and extends from the first insulating member 13 through the through hole 14 (see FIG. 1A). It moves in a direction toward the second insulating member 23 . At this time, the spring portion 31 biases the shield member 30 from the second insulating member 23 toward the first insulating member 13 . The biasing force of the spring portion 31 increases as the amount of movement of the shield member 30 increases.

The shield member 30 and the electrodes of the first circuit board 110 may be electrically connected via a conductive bonding material 40 such as solder. Also, the shield member 30 may have a structure in which it is in direct contact with the first circuit board 110 .

In general, a ground conductor (ground electrode) is often provided on a circuit board in order to prevent signals from the circuit board from leaking to the outside and electromagnetic waves from the outside from interfering with signal lines on the circuit board. For example, when a pair of circuit boards has ground conductors with different thicknesses, signal reflection is likely to occur on the side of the circuit board with the thin ground conductor. When signals are reflected, interference between signals tends to occur, and isolation between internal terminal groups provided on the circuit board tends to decrease. In the second embodiment, the spring portion 31 improves the adhesion between the first circuit board 110 and the shield member 30, and improves the isolation between the first internal terminal group 11A and the second internal terminal group 12A. . Therefore, in the second embodiment, the thickness of the first ground conductor 113 provided at the position closest to the shield member 30 on the first circuit board 110 is set to the thickness of the first ground conductor 113 at the position closest to the shield member 30 on the second circuit board 120. It is configured to be thinner than the thickness of the second ground conductor 123 provided. According to such a configuration, it is possible to suppress deterioration in isolation between the first internal terminal group 11A and the second internal terminal group 12A.

Further, as shown in FIG. 4A, the spring portion 31 has a leg portion 31a having a portion extending in the Y direction, but the present invention is not limited to this. For example, as shown in FIG. 6, the spring portion 131 may be in the form of a leg portion 131a extending along the longitudinal direction of the shield member . Moreover, when the shield member 130 is viewed from the Z direction, the leg portion 131a is provided at a position where at least a portion of the leg portion 131a overlaps the shield member 130. As shown in FIG. With such a configuration, the shield member 130 can be installed on the second insulating member 23 in a space-saving manner. The spring portion 31 may be a coil spring configured separately, but is configured to include a pair of leg portions 31a extending from the bottom surface of the shield member 30 in the Y direction when viewed from the Z direction (see FIG. 4A). is preferable because the shield member is less likely to shift in the Y direction.

According to the circuit board connection structure 100 according to the second embodiment, the shield member 30 that is movable in the Z direction through the through hole 14 is arranged between the first internal terminal group 11A and the second internal terminal group 12A. be done. Also, in the multipolar connector set 1, the shield member 30 is directed from the second insulating member 23 to the first insulating member 13 in a state where the first connector 10 and the second connector 20 are fitted to each other. A spring portion 31 is provided to urge the shield member 30 in the direction to contact the first circuit board 110 through the through hole. When the first connector 10 and the second connector 20 are mated, the spring portion 31 urges the shield member 30 toward the first circuit board 110 to separate the shield member 30 and the first circuit board 110 from each other. can increase the adhesion of. As a result, it is possible to suppress the transmission of signals between the first internal terminal group 11A and the second internal terminal group 12A. Isolation between can be improved.

According to the circuit board connection structure 100 according to the second embodiment, the thickness of the first ground conductor 113 provided at the position closest to the shield member on the first circuit board 110 is the same as that of the shield member on the second circuit board 120 . It is thinner than the thickness of the second ground conductor 123 provided closest to the member 30 . According to such a configuration, even when the electromagnetic wave reflected from the first ground conductor 113 is larger than the electromagnetic wave reflected from the second ground conductor 123, the first internal terminal group 11A and the second can improve the isolation of the internal terminal group 12A.
