The claw portion 34 of the locking piece 33 reaches the recess 36 of the socket body 15.

  As a result, the locking piece 33 is restored by the elastic force, the claw 34 is caught in the recess 36, the locking piece 33 of the guide member 16 inserted from above is fitted into the socket body 15, and a new guide member 16 is mounted. can do.

  Thereafter, the pad 21 is inserted through the opening 37 of the operation member 20 in a state where the pad 21 is inclined as shown in FIGS. Then, the pair of pivot protrusions 44 of the pad 21 are arranged in the vicinity of the pivot support part 45 of the guide member 16 and are elastically displaced by applying pressure from both sides to fit the pivot protrusions 44 to the pivot support part 45. Thus, the pad 21 can be attached to the new guide member 16.

  In such an IC socket 10, the guide member 16 for positioning the IC package 12 accommodated in the accommodating portion 14 of the socket body 15 is formed to be smaller than the opening 37 of the operation member 20, and passes through the opening 37. Since it can be attached to and detached from the socket body 15, the guide member 16 can be easily mounted or replaced without removing the operation member 20.

  Therefore, even when the size of the IC package 12 is changed, or when the guide member 16 is replaced due to deterioration of the pad 21 or the guide member 16, the operation member 20 is removed from the IC socket 10 mounted on the wiring board 11. The guide member 16 can be easily attached and detached without removing it.

  In addition, the guide member 16 has a locking piece 33 that is locked to the socket body 15, and the locking piece 33 is formed so as to be able to be unlocked by applying an external force from the outside. It can be easily attached to or detached from the socket body 15.

  Further, since the pad 21 is formed in a size that can pass through the opening 37 and is directly pivotally supported by the guide member 16 so as to be freely opened and closed, the support structure of the pad 21 can be simply configured. It can be easily attached and detached from the inside.

  Moreover, since the pad 21 covers the upper side of the IC package 12 in a closed state, it is possible to prevent foreign matter from adhering to the upper surface of the IC package 12 during use. Even if such a pad 21 is provided, since the pad 21 is formed smaller than the opening 37, it can be easily taken out from the opening 37 of the operation member 20, and the guide member 16 can be easily attached and detached. Can be prevented.

  Further, since the pad 21 is pivotally supported by the guide member 16 and has the first and second pressed portions 47 and 48 that are rotated by being pressed by the operation member 20, the pad 21 is opened and closed. The mechanism for making it possible can be configured simply. Therefore, it can prevent that the attachment or detachment of the guide member 16 and the pad 21 is inhibited, and can be attached / detached more favorably.

  In addition, the said embodiment can be suitably changed within the scope of the present invention. For example, in the above description, an example in which the pad 21 that covers the entire upper side of the IC package 12 and contacts the guide member 16 is provided as the opening / closing body attached to the guide member 16 is not particularly limited. For example, a pad that contacts the IC package 12 and covers the whole or a part of the upper surface of the IC package 12 may be used. Further, the opening / closing body attached to the guide member 16 does not have to cover the IC package 12. For example, the present invention is similarly applied to a latch for strongly pressing the IC package 12 downward. Is possible.

  Further, in the above embodiment, when removing the pad 21 and the guide member 16, the pad 21 is first removed and detached from the opening 37 of the operation member 20, and then the guide member 16 is removed from the opening 37 of the operation member 20. Although an example in which the guide member 16 is detached has been described, the guide member 16 may be detached from the socket body 15 and detached from the opening 37 of the operation member 20 while the pad 21 is attached to the guide member 16.

  Further, in the above embodiment, each locking piece 33 of the guide member 16 is provided with the claw portion 34. However, by moving the guide member 16 close to and away from the socket body 15 from above, the locking piece 33 is If the socket body 15 can be engaged and disengaged by elasticity, the claw portion 34 may not be provided. Further, the number, position, orientation, and the like of each locking piece 33 can be changed as appropriate.

  The locking piece 33 provided on the guide member 16 may not be structured to be locked to the socket body 15. For example, the locking piece 33 may be provided on the socket body 15.
