Then, the pushing portions 31 and 32 are pushed down as they are in contact with the pushed portions 42 and 46 against the urging force of the urging means of the operation member 30, so that the round shaped pushing portions 31 and 32 are pressed. The pushed parts 42 and 46 are moved outward along the shape of the first and second shafts 41a and 45a against the urging force of the urging means of the first latch 41 and the second latch 45. As a center, the first latch 41 and the second latch 45 are rotated outward to be in an open state.

  Further, since the operation member 30 is urged upward with respect to the socket body 20 by an urging means (not shown), when the downward push is released, the operation member 30 is urged upward and the pushing portions 31, 32 is separated from the pushed parts 42 and 46, and the pushing to the pushed parts 42 and 46 is released. Thereafter, the projections 35 and 36 of the operating member 30 abut against the pressed portions 42 and 46 and are lifted from below, whereby the first latch 41 and the second latch 45 are rotated inwardly about the shafts 41a and 45a. The first latch 41 and the second latch 45 are configured to maintain a closed state.

  Further, as shown in FIG. 2, the operation member 30 has an action portion 33 that comes into contact with the actuated portion 75 of the second pusher 71 from above. This action part 33 is lowered as shown by a two-dot chain line, abuts against the actuated part 75, and further pushed downward, so that the action part 33 slides relative to the actuated part 75 The actuated portion 75 is pushed outward and the second pusher 71 of the positioning press portion 70 is slid outward.

  Next, the operation of the IC socket 10 having such a configuration will be described.

  First, as shown in the order of FIG. 3 → FIG. 4 → FIG. 5, the operating member 30 is pushed down against the urging force of the urging means, and the pushed portions 42 and 2 of the first latch 41 are pushed by the pushing portions 31 and 32. The pushed portion 46 of the latch 45 is pushed in. Then, the first latch 41 and the second latch 45 are rotated outward to open, and the housing portion 26 is opened. In this state, the IC package 2 is accommodated in the accommodating portion 26 by an automatic machine (not shown). At this time, the respective recesses 5 of the IC package 2 are accommodated so as to be inserted into the guide pins 27, 28, 64, 74.

  Next, as shown in the order of FIG. 5 → FIG. 4 → FIG. 3, the pressing of the operating member 30 is released and the operating member 30 is moved upward by the biasing force of the biasing means. Then, the pressing of the pressing portions 31 and 32 to the pressed portions 42 and 46 is released, and then the projections 35 and 36 of the operation member 30 abut against the pressed portions 42 and 46 and are lifted from below, so that the first The latch 41 and the second latch 45 rotate inward about the shafts 41a and 45a, and rotate in a direction in which the first latch 41 and the second latch 45 are closed.

  Further, due to the urging force of the spring 62, the inner peripheral surface 44 c on the side of the second through hole 43 f of the projecting portion 44 is located closer to the outer peripheral surface 67 of the pusher 61 from the thick outer end portion 44 b to the thin accommodating portion 26 side. As the state shifts to the end 44 a, the engagement between the inner peripheral surface 44 c of the protruding portion 44 of the first latch 41 and the outer peripheral surface 67 of the pusher 61 is released, and the outer side of the housing portion 26 of the pusher 61 is released. The inner peripheral surface 44c on the second through hole 43f side of the projecting portion 44 is finally separated from the lower side of the outer peripheral surface 67 of the pusher 61, and the center portion of the housing portion 26 of the spring 62 is released. The pusher 61 presses the side surface 6 of the IC package 2 by the biasing force.

  At this time, the guide pins 27, 28, 64, and 74 are inserted into the concave portion 5 of the IC package 2 and there is a margin of a predetermined width, so that the IC package 2 is accommodated by the pressing of the pusher 61. 26 toward the wall surface on the opposite side.

  Similarly, as the operating member 30 moves upward, the action part 33 is separated from the actuated part 75 of the second pusher 71, and the second spring 72 is biased by the biasing force toward the center of the accommodating part 26. The 2 pusher 71 presses the side surface 6 of the IC package 2. At that time, since the guide pins 27, 28, 64, 74 are inserted into the recesses 5 of the IC package 2 and there is a margin of a predetermined width, the IC package 2 is pressed by the pressing of the second pusher 71. It is brought close to the wall surface direction on the opposite side of the accommodating portion 26.

  As a result, the IC package 2 is shifted from one side to the other side in two directions substantially orthogonal to each other, and as a result, positioning is performed.

  Thereafter, the protrusions 35 and 36 of the operation member 30 further lift the pushed portions 42 and 46 from below, whereby the first latch 41 and the second latch 45 further rotate inward about the shafts 41a and 45a, The first latch 41 and the second latch 45 press the upper surface 7 of the IC package 2 and maintain the closed state. Further, the pressing force of the first latch 41 and the second latch 45 causes the floating portion 25 to sink downward by a certain amount, and the contact pressure between the contact pin 50 and the IC package 2 is increased.

  At this time, the projections 35 and 36 of the operation member 30 abut against the pressed portions 42 and 46 and are lifted from below, so that the first latch 41 and the second latch 45 are rotated inward about the shafts 41a and 45a. The first latch 41 and the second latch 45 come into contact with and press against the upper surface 7 of the IC package 2 so that the upper surface 7 of the IC package 2 can be pressed with a constant force.

  In this way, the positioning is performed by shifting and the test is performed.

  Further, after the test, as shown in the order of FIG. 3 → FIG. 4 → FIG. 5, the operation member 30 is pushed down against the biasing means, and the pushed portions 42 of the first latch 41 are pushed by the pushing portions 31, 32. And the pushed portion 46 of the second latch 45 is pushed. As a result, the first latch 41 and the second latch 45 are rotated outward to bring the housing portion 26 into an open state, and the IC package 2 is taken out of the housing portion 26 by an unillustrated automatic machine or the like.

  At this time, the pushing portions 31 and 32 push the pushed portions 42 and 46, and the first latch 41 and the second latch 45 are rotated in the opening direction against the urging force of the urging means. Accordingly, the first latch 41 and the second latch 45 are separated from the upper surface 7, and accordingly, the pressing of the floating portion 25 that accommodates the IC package 2 in the accommodating portion 26 is released, and the floating portion 25 is moved upward by the urging means. Moving.

  In this state, when the first latch 41 is further rotated in the opening direction, the inner peripheral surface 44c on the second through hole 43f side of the projecting portion 44 comes into contact with the outer peripheral surface 67 of the pusher 61 and slides from below. Then, as the end 44a on the thin accommodating portion 26 side gradually moves to the thick outer end 44b, the pusher 61 is pressed toward the outer side of the accommodating portion 26, and the center of the accommodating portion 26 of the spring 62 is pressed. The pusher 61 acts away from the IC package 2 against the urging force in the direction.

  Similarly, as the operating member 30 is pushed downward, the acting portion 33 of the operating member 30 comes into contact with the actuated portion 75 of the second pusher 71, and the pushing portion further slides to accommodate the spring 72. The action part 33 pushes the actuated part 75 outwardly against the urging force of the part 26 in the opposite direction. Thereby, the 2nd pusher 71 leaves | separates from the side surface 6 of IC package 2, the press by the 2nd pusher 71 is cancelled | released, and positioning is cancelled | released.

  In this way, the pressing of the first latch 41 and the second latch 45 is released, and the positioning of the pusher 61 and the second pusher 71 is released, so that the IC package 2 can be taken out.

  According to this embodiment, the pusher 61 that presses the IC package 2 when the first latch 41 is closed by being moved by the opening and closing operation of the first latch 41 is provided. Since the pusher 61 does not protrude outward and the compact outer shape is maintained, the outer dimensions of each IC package 2 vary with respect to the IC package 2. Therefore, positioning can be performed reliably, and as a result, contact failure with the IC package 2 can be prevented and a normal test can be performed.

  Further, according to this embodiment, the pusher 61 presses the side surface 6 of the IC package 2 to complete positioning, and then the first latch 41 presses the upper surface 5 of the IC package 2. As a result, the IC package 2 can be smoothly positioned to held.

  Further, according to this embodiment, the pusher 61 is pushed using the biasing force of the spring 62, and the pusher 61 is pulled using the action of the first latch 41. Can be performed smoothly.

  Further, according to this embodiment, when the first latch 41 and the second latch 45 that press the upper surfaces 7 on both sides facing the IC package 2 are provided, the first latch 41 is closed. The pusher 61 that presses the IC package 2 in the center direction of the housing portion 26 by rotating, and the IC package 2 is pressed in a direction substantially orthogonal to the direction in which the pusher 61 of the housing portion 26 presses by raising the operation member 30. Since the second pusher 71 and the second pusher 71 are configured to perform the justification, the justification can be reliably performed.

  In addition, the “electrical component socket” of the present invention is not limited to the structure as in the above-described embodiment, but can be applied to other structures such as devices other than the IC socket.

  Further, the shape, size, and the like of the electrical component are not limited to those in the above-described embodiment, and may be used for positioning electrical components having other different shapes.

  Further, in the above-described embodiment, the first latch 41 and the second latch 45 are provided so as to face both side portions of the accommodating portion 26, and the first latch 41 and the second latch 45 are provided. The latches are not provided on both sides orthogonal to both sides of the accommodating portion 26, but the present invention is not limited to this. For example, the accommodating portion has a substantially square shape, and the latch is provided opposite to both sides of the accommodating portion, and is also provided opposite to both sides of the accommodating portion in a direction substantially orthogonal thereto. Pushers are provided on the latch sides of the both sides of the accommodating portion in the substantially orthogonal direction, and each of the urging means for urging each pusher when the respective latches are rotated in the closing direction. Each pusher is moved in a substantially orthogonal direction by an urging force, and the side surface of the electrical component is pressed in the central direction of the accommodating portion that is substantially orthogonal, so that the electrical component is aligned and positioned. Also good.

  According to such a configuration, when the electric component has a latch that presses the upper surfaces of all four sides around the electric component, the electric component is accommodated by rotating the latch in the closing direction. Since the two pushers that press in the center direction of the substantially orthogonal direction are provided, it is compact and can be positively aligned according to the operation of the latch.
