[0087] Referring to FIGS. 9 and 10, the shuttle key (400) can be positioned in the third shuttle key hole (443) or pass through the third shuttle key hole (443) regardless of the rotation direction with respect to the central axis.

[0088] The shuttle key (400) can be located in the second shuttle key hole (442) or pass through the second shuttle key hole (442) when the first direction, which is the direction in which the first support member (410) extends, matches the fourth direction, which is the direction in which the second shuttle key hole (442) extends.

[0089] The shuttle key (400) can be positioned in the first shuttle key hole (441) or pass through the first shuttle key hole (441) when the first direction, which is the direction in which the first support member (410) extends, matches the third direction, which is the direction in which the first shuttle key hole (441) extends (first state).

[0090] The first support part (410) of the shuttle key (400) can pass through the second shuttle key hole (442) of the housing part (210) when the first direction and the fourth direction are aligned, and in this case, the second support part (420) of the shuttle key (400) cannot pass through the second shuttle key hole (442) of the housing part (210) because the second direction and the fourth direction are not aligned.

[0091] The first support part (410) of the shuttle key (400) can pass through the first shuttle key hole (441) of the floating part (100) in a state where the first direction and the third direction are aligned (first state). In this case, the second support part (420) of the shuttle key (400) can pass through the second shuttle key hole (442) of the housing part (210) because the second direction and the fourth direction are aligned.

[0092] When at least a part of the shuttle key (400) (or the first support member (410)) passes through the first shuttle key hole (441) and rotates at least 90 degrees, the first direction becomes different from (or perpendicular to) the third direction (second state), and the first support member (410) can support the floating member (100).

[0093] When at least a part of the shuttle key (400) (or the first support member (410)) passes through the first shuttle key hole (441) and rotates at least 90 degrees, the second direction may not coincide with (or be perpendicular to) the fourth direction, and the second support member (420) may support the fixed member (200).

[0094] When the first direction, which is the extension direction of the first support part (410), and the third direction, which is the extension direction of the first shuttle key hole (441), become inconsistent (second state), and the second direction, which is the extension direction of the second support part (420), and the fourth direction, which is the extension direction of the second shuttle key hole (442), become inconsistent, the shuttle key (400) connects the floating part (100) and the fixed part (200) while penetrating the first shuttle key hole (441) and the second shuttle key hole (442). At this time, the floating part (100) can descend and ascend together with the compression and extension of the elastic part (300) located between the floating part (100) and the fixed part (200).

[0095] According to an embodiment of the present invention, a test socket (10) can be coupled to a fixed part (200) so that the floating part (100) can be raised and lowered only by a rotation of at least 90 degrees of the shuttle key (400).

[0096] Since the shuttle key (400) supports the floating part (100) by making surface contact with the upper surface of the floating part (100) through the lower surface of the first support part (410) and supports the fixed part (200) by making surface contact with the lower surface of the housing part (210) through the upper surface of the second support part (420), the floating part (100) and the fixed part (200) can be joined more stably despite repeated rising and falling of the floating part (100).

[0097] Since the floating part (100) is fixed while the shuttle key (400) penetrates both the upper and lower surfaces of the floating part (100) and the upper and lower surfaces of the housing part (210), the floating part (100) can be provided with a first shuttle key hole (441) in which the shape and width of the cross section are maintained (stepless). The stepless first shuttle key hole (441) can reduce the manufacturing difficulty, manufacturing cost, and manufacturing time of the floating part (100).

[0098] Additionally, the housing portion (210) may be provided with a second shuttle key hole (442) without a step. The second shuttle key hole (442) without a step may reduce the manufacturing difficulty, manufacturing cost, and manufacturing time of the housing portion (210).

[0099] In addition, since the second support portion (420) of the shuttle key (400) provides a rotatable space, the base portion (220) can be provided with a third shuttle key hole (443) without a step. The third shuttle key hole (443) without a step can reduce the manufacturing difficulty, manufacturing cost, and manufacturing time of the base portion (220).

[0100] With continued reference to FIG. 10, the test socket (10) according to an embodiment of the present invention may further include a rotation prevention portion (730) that is provided to be in contact with at least a portion of the first support portion (410) and prevents rotation of the shuttle key (400). The floating portion (100) may include a floating rotation prevention hole (733) through which the rotation prevention portion (730) passes. The housing portion (210) may include a housing rotation prevention hole (734) through which at least a portion of the rotation prevention portion (730) passes.

[0101] The anti-rotation part (730) may be provided one or more times for each shuttle key (400). At least one floating anti-rotation hole (733) and one housing anti-rotation hole (734) may be provided. A first shuttle key hole (441) may be located between a pair of floating anti-rotation holes (733). A second shuttle key hole (442) may be located between a pair of housing anti-rotation holes (734).

[0102] The anti-rotation part (730) may include an exposed anti-rotation part (731) and a through-rotation part (732). The exposed anti-rotation part (731) may refer to an area exposed through the upper surface of the floating part (100) when the anti-rotation part (730) is fixed to the floating part (100). The through-rotation part (732) may refer to an area where the anti-rotation part (730) passes through the floating anti-rotation hole (733) when the anti-rotation part (730) is fixed to the floating part (100).

[0103] The shuttle key (400) connects the floating part (100) and the fixed part (200) in the first state, and a pair of anti-rotation parts (730) can be connected to the floating part (100) with the shuttle key (400) interposed therebetween. The pair of anti-rotation parts (730) are provided so as to be in contact with both sides forming the width of the shuttle key (400) so as to prevent rotation of the shuttle key (400).

[0104] The exposed rotation prevention part (731) prevents rotation of the shuttle key (400) by contacting the first support part (410) and blocks a part of the first shuttle key hole (441) from above so that the first support part (410) cannot pass through the first shuttle key hole (441). The exposed rotation prevention part (731) can cover a part of the long width of the first shuttle key hole (441) and close a part of the first shuttle key hole (441) from above.

[0105] When the floating part (100) descends, at least a portion of the through-rotation preventing part (732) can move along the housing rotation preventing hole (734). The through-rotation preventing part (732) can move within the housing rotation preventing hole (734) to prevent the floating part (100) from being misaligned in the horizontal direction when descending.

[0106] The floating portion (100) may be provided with a stepless floating anti-rotation hole (733). The housing portion (210) may be provided with a stepless housing anti-rotation hole (734). The stepless floating anti-rotation hole (733) and the housing anti-rotation hole (734) may reduce the manufacturing difficulty, manufacturing cost, and manufacturing time of the floating portion (100) and the housing portion (210), respectively.

[0107] The test object according to the embodiment of the present invention can be manufactured using a simple processing method because each of the various holes provided in at least one of the floating part (100), the housing part (210), and the base part (220) is manufactured without steps.

[0108] As described above, the present invention has been described with reference to preferred embodiments thereof, but it will be apparent to those skilled in the art that various modifications or variations may be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following claims.
