  However, in the invention described in Patent Document 1, when the operation member is lowered and the pressed portion (operation piece 16i) is pressed so that the conduction contact portion is retracted from the electrical component, the conduction member is used. There is a possibility that the contact portion may be scratched while pressing the terminal of the electrical component downward.

  In the invention described in Patent Document 1, for example, when inspecting a CCD (solid-state imaging device, the same applies hereinafter), the CCD is moved to the housing member by the handler above the socket for the electrical component, and the electrical component is The light source is irradiated with light from the top of the socket, but the number of sockets for electrical components that can be attached to the board is large in order to determine the arrangement of the handler and the light source so as not to interfere with the light source. There is a risk that the number of CCD inspections that can be inspected at a time may be reduced, and the distance between the light source and the CCD may be increased.

  Accordingly, an object of the present invention is to provide an electrical component socket that does not have a risk of the conductive contact portion pressing and scratching the electrical component when the operation member is lowered.

  Another object of the present invention is to provide an electrical component inspection system capable of increasing the number of CCD inspections that can be performed at one time and reducing the distance between the light source and the CCD.

  In order to achieve this object, the invention according to claim 1 is provided with a contact pin that comes into contact with a terminal of an electrical component, a socket body mounted on a substrate, and a vertically movable body on the socket body. A socket for an electrical component provided with an operating member and a housing member that is integrally movable with the operating member and accommodates the electrical component, wherein the contact pin is fixed to the socket body.

After the electrical component is separated from the conductive contact portion, the pressing portion presses the pressed portion and the swinging linear portion is retracted from the electrical component, so that the conductive contact portion is the electrical component. When the operating member is lifted apart from the component, the pressing portion releases the pressed portion and the swinging linear portion approaches the electric component, so that the conduction contact portion becomes the electric component. The electrical component accommodated in the housing member rises after approaching the component, whereby the electrical component is a socket for electrical component that contacts the contact portion for conduction.

  According to a second aspect of the present invention, in addition to the structure of the first aspect, the contact pin extends in a substantially horizontal direction from the tip of the oscillating straight line portion, and the electric component accommodated in the accommodating member. In addition to the conductive contact portion that comes into contact with the terminal from above, it extends downward from the tip of the oscillating linear portion, contacts the side surface of the housing member from the side, and is prevented from swinging in the lateral direction.

In addition, it is possible to guide so that the contact portion for conduction can contact the terminal of the electrical component without fail.

  According to the third aspect of the present invention, the accommodating member that can move up and down on the lower side of the socket main body is provided so as to protrude below the substrate through the through hole formed in the substrate. Therefore, since the board is not disposed on the lower side of the socket main body, it is possible to save the space for the inspection of the electric parts by the thickness of the board.

It is accommodated in the step part. Therefore, a handler can be provided on the upper side of the socket body to move the electrical component, and a light source can be provided on the lower side of the socket body to irradiate the electrical component with light. Therefore, for example, when the electrical component is a CCD, it is possible to avoid the concentration of both the handler and the light source above the electrical component socket as in the prior art, and the electrical component that can be inspected at one time. The number of inspections can be increased.

  In addition, since no handler is provided between the light source and the CCD, the distance between the light source and the CCD can be reduced. Therefore, the light from the light source can be used effectively for the inspection of the CCD.

  According to the fifth aspect of the present invention, an electrical component inspection system includes an electrical component socket, and a light source that is disposed below the housing member and is irradiated toward the electrical component through the through hole of the through wall.

  As shown in FIG. 7, the CCD 1 has a light introduction surface 1b for introducing light and a terminal surface 1a provided with a terminal 1p through which electricity converted from the light is passed. As shown in FIGS. 5 and 6A and 6B, the CCD 1 is housed in a step portion 13n formed in the housing member 13 so that the light introduction surface 1b faces downward.

  Then, as shown in FIGS. 1 and 5, the inspection system 8 for the CCD 1 that is an “electrical component” is disposed below the electrical component socket 10 and the receiving member 13 and faces the CCD 1 through the through wall 13m. And the light source 2 to be irradiated.

  Next, the operation of the electrical component socket 10 and the inspection method of the CCD 1 according to the embodiment of the present invention will be described.

  First, when the operation member 12 is lowered, the electric component insertion through wall 12m of the operation member 12 is lowered along the swinging linear portion 30d of the contact pin 30 as shown in FIGS. 5 to 6A. The housing member 13 housing the CCD 1 is lowered. Accordingly, the CCD 1 moves in a direction away from the conduction contact portion 30f in the downward direction.

  When the operating member 12 is further lowered, the pressing portion 12n of the operating member 12 comes into contact with the pressed portion 30e of the contact pin 30 and presses the pressed portion 30e as shown in FIG. The housing member 13 housing the CCD 1 is further lowered.

  When the operating member 12 is further lowered, the pressing portion 12n presses over the pressed portion 30e of the contact pin 30 as shown in FIG. 6B, and the swing linear portion 30d is pushed outward. The conducting contact portion 30g provided at the tip of the swing linear portion 30d is retracted from the CCD 1 side. Further, the lateral movement restraining contact portion 30 f retracts from the outer surface of the through wall 13 m of the housing member 13. In this state, as shown in FIG. 5, the CCD 1 is moved by a handler (not shown) and accommodated in the stepped portion 13 n of the accommodating member 13 so that the terminal surface 1 a faces upward.

  In this state, when the operating member 12 is raised, the pressing portion 12n of the operating member 12 descends the pressed portion 30e of the contact pin 30 as shown in FIGS. 6 (B) to 6 (A). However, by releasing the pressure on the pressed part 30e, the swinging linear part 30d stops pushing the pressed part 30e outward, and tries to return to the original shape by the elastic force of the spiral part 30c. 13 approaches the outer surface of the through wall 13m. Thereby, the contact part 30g for conduction | electrical_connection is arrange | positioned above the terminal 1p of CCD1.

  When the operating member 12 is further raised, as shown in FIG. 6A, the pressing portion 12n completely descends the pressed portion 30e of the contact pin 30, and the receiving member 13 that houses the CCD 1 further rises. Thus, the conductive contact portion 30g is in contact with the terminal surface 1a of the CCD 1. In this state, the CCD 1 is inspected by irradiating the CCD 1 with light from the light source 2. At this time, the lateral movement restraining contact portion 30f comes into contact with the outer surface of the through wall 13m of the housing member 13, and the conduction contact portion 30g does not slide on the terminal 1p of the CCD 1 more than necessary. ing.

  When the operation member 12 is further raised, the electric component insertion through wall 12m of the operation member 12 rises along the swinging linear portion 30d of the contact pin 30 and the CCD 1 is accommodated as shown in FIG. The member 13 rises.

  According to such an electrical component socket 10, the housing member 13 that houses the CCD 1 is provided so as to be movable up and down integrally with the operation member 12. Therefore, when the operation member 12 is lowered, the accommodation member 13 in which the CCD 1 is accommodated is lowered together with the operation member 12 before the conduction contact portion 30 g presses and scratches the CCD 1. Therefore, when the operation member 12 is lowered, the conduction contact portion 30g can be prevented from being scratched while pressing the CCD 1. Further, since the operation of the operation member 12 can be used as it is for the operation of the housing member 13, it is not necessary to configure the lift mechanism of the storage member 13 separately from the lift mechanism of the operation member 12.

  Contrary to what has been described above, when the operation member 12 is raised, the accommodating member 13 for accommodating the CCD 1 is raised together with the operation member 12 after the conducting contact portion 30g swings toward the CCD 1 side. Accordingly, the conduction contact portion 30g can reliably contact the terminal 1p of the CCD 1.

  As described above, when the contact portion 30g for conduction and the CCD 1 are in contact, the contact portion 30g for conduction and the CCD 1 are moved in a direction approaching each other, and when the contact portion 30g for conduction is separated from the CCD 1, the contact for conduction is provided. The part 30g and the CCD 1 are moved away from each other. Therefore, even if the operating member 12 is not raised or lowered by the amount that the CCD 1 is raised or lowered, the contact part 30g for conduction and the CCD 1 can be contacted or released.

  Further, the contact pin 30 extends in a substantially horizontal direction from the tip of the oscillating linear portion 30d, and in addition to the conducting contact portion 30g that contacts the terminal 1p of the CCD 1 accommodated in the accommodating member 13 from above, the oscillating linear portion 30 A lateral movement restraining contact portion 30f that extends downward from the tip of the portion 30d and contacts the side surface of the housing member 13 from the lateral side to restrain lateral swinging is provided. Therefore, before the contact portion 30g for conduction contacts the terminal 1p of the CCD 1, the lateral movement stop contact portion 30f abuts against the side surface of the housing member 13, and the contact portion 30g for conduction provides the terminal 1p in the CCD 1 more than necessary. It can be prevented from moving to a portion that is not provided, and can be guided so that the contact portion 30g for conduction can reliably contact the terminal 1p of the CCD 1.

  Further, an accommodation member 13 that can move up and down below the socket body 11 is provided so as to protrude below the substrate 14 through a through hole 14 a formed in the substrate 14. Accordingly, since the substrate 14 is not disposed below the socket body 11, it is possible to save the space for the inspection of the CCD 1 by the thickness of the substrate 14.

  In addition, the housing member 13 is provided with a through wall 13m in which a through hole 13m-1 penetrating in the vertical direction is formed. A step portion 13n for housing the CCD 1 is formed on the inner wall of the through wall 13m. The CCD 1 has a light introduction surface 1b for introducing light and a terminal surface 1a provided with a terminal 1p through which electricity converted from light is passed. The CCD 1 has a light introduction surface 1b directed downward so that the housing member 13 It is accommodated in the step part 13n. Therefore, the CCD 1 can be moved by providing a handler above the socket main body 11, and the light source 2 can be provided below the socket main body 11 to irradiate the CCD 1 with light. Therefore, for example, in the case of the CCD 1, it is possible to avoid the concentration of both the handler and the light source 2 above the electrical component socket 10 as in the prior art, and the inspection of the CCD 1 that can be inspected at a time. The number can be increased.

  In addition, since no handler is provided between the light source 2 and the CCD 1, the distance between the light source 2 and the CCD 1 can be reduced. Therefore, the light from the light source 2 can be used effectively for the inspection of the CCD 1.

  The CCD 1 inspection system further includes an electrical component socket 10 and a light source 2 that is disposed below the housing member 13 and is irradiated toward the CCD 1 through the through hole 13m-1 of the through wall 13m. Therefore, for example, in the case of the CCD 1, it is possible to avoid the concentration of both the handler and the light source 2 above the electrical component socket 10 as in the prior art. Further, the light from the light source 2 can be effectively used for the inspection of the CCD 1.

  In addition, the oscillating linear portion 30d is provided with a pressed portion 30e and a conduction contact portion 30g so as to protrude in the same direction. Therefore, the operation of pressing or releasing the pressing to the pressed portion 30e by the pressing portion 12n of the operating member 12 can directly be the operation of the contact portion for conduction 30g.

  In addition, although the socket 10 for electrical components in embodiment of this invention was used for the test of CCD1, it is not limited to the said embodiment. That is, the electrical component socket 10 can also be used for testing electrical components other than the CCD 1, such as an IC package.
