The arrangement direction of the plurality of coil terminals 300 is defined as a second direction, and the first direction and the second direction are perpendicular to each other.

If the coil terminals 300 are of a sheet-like structure, the width of each coil terminal 300 extends in the direction in which the plurality of coil terminals 300 are arranged, the overall width of the plurality of coil terminals 300 in the direction in which they are arranged is relatively large, resulting in a relatively large overall occupation space of the relay socket structure 10. Therefore, the coil outlets 300 are in a needle-shaped structure, so that the width of each coil outlet 300 along the arrangement direction of the plurality of coil outlets 300 is shortened, and then the overall width of the plurality of coil outlets 300 along the arrangement direction is smaller, so that the overall occupied space of the relay socket structure 10 is smaller, the structure is compact, the occupied space is smaller, and the light-weight requirement is met.

If the auxiliary stationary contact conductive members 40 are of a sheet-like structure, the width of each auxiliary stationary contact conductive member 40 extends in the arrangement direction of the plurality of auxiliary stationary contact conductive members 40, and the overall width of the plurality of auxiliary stationary contact conductive members 40 in the arrangement direction thereof is relatively large, resulting in relatively large overall occupation space of the relay socket structure 10. Therefore, the auxiliary static contact conductive members 40 are in a needle-shaped structure, so that the width of each auxiliary static contact conductive member 40 along the arrangement direction of the plurality of auxiliary static contact conductive members 40 is shortened, and then the overall width of the plurality of auxiliary static contact conductive members 40 along the arrangement direction is smaller, so that the overall occupied space of the relay socket structure 10 is smaller, the structure is compact, the occupied space is smaller, and the light-weight requirement is met.

It is understood that the plurality of coil outlets 300 and the plurality of auxiliary stationary contact conductive members 40 may be arranged along a line shape, and the coil outlets 300 and the auxiliary stationary contact conductive members 40 may be in a needle-shaped structure, so as to further reduce the overall occupation space of the relay socket structure 10.
