One end of the fixing portion 14F is connected to a connector that is movably supported. Note that one end of the fixing portion 14F is not limited to such an example, and may be configured to be connected to a predetermined lead wire instead of the connector.

  The cover member 10U is formed of, for example, a resin material and is coupled to the end portion of the main body case 10L. As shown in FIGS. 1 and 2, the cover member 10 </ b> U has an opening 10 </ b> UD in the center part into which the pressure receiving part 12 </ b> P of the contact support 12 is slidably inserted. The cover member 10U and the body case 10L form a housing.

  The opening 10UD is formed in a substantially rectangular shape corresponding to the shape of the pressure receiving surface of the pressure receiving portion 12P of the contact support 12. At four locations around the opening 10UD, holes 10Ua into which the guide pins BS are inserted are formed at predetermined intervals. As shown in FIG. 4A, the hole 10Ua is formed of two large diameter portions and a small diameter portion. One of the two large-diameter portions accommodates the head portion and the shaft portion of the guide pin BS. The other large-diameter portion accommodates a coil spring SP1 wound around the outer peripheral portion of the shaft portion of the guide pin BS. The coil spring SP1 is disposed between the stopper plate 16 and a spring receiving portion in which a small diameter portion is formed in the hole 10Ua. Each coil spring SP1 urges the stopper plate 16 connected to the male thread portion of the shaft portion of each guide pin BS in a direction to separate the stopper plate 16 toward the spring accommodating portion 10Lb of the main body portion 10L.

  The small diameter portion formed between the large diameter portions guides the shaft portion of the guide pin BS so as to be slidable. An opening end connected to the end of the main body case 10L in the cover member 10U communicates with the opening 10UD. Between the opening end coupled to the end portion of the main body case 10L in the cover member 10U and the end portion of the opening portion 10UD, a guide portion that accommodates the stopper plate 16 and guides the stopper plate 16 so as to be movable by a predetermined stroke is formed. Yes. The outer peripheral surface of the stopper plate 16 is in sliding contact with the inner peripheral surface of the guide portion.

  The stopper plate 16 is formed, for example, in a flat plate shape with a resin material, and has an opening 16D having a shape corresponding to the opening 10UD of the cover member 10U at the center. Around the opening 16D, female screw portions 16fs into which the male screw portions of the respective guide pins BS are screwed are formed at four positions with a predetermined interval. Thereby, the stopper plate 16 is urged | biased and made to contact toward the guide part 12B of the contact support body 12 by the urging | biasing force of each coil spring SP1. As a result, when the contact support 12 is pressed against the spring accommodating portion 10Lb of the main body 10L against the urging force of the pressing spring SP2, the stopper plate 16 has the second portions 14Mb of the contact terminals 14Rai and 14Lai. When the head of the guide pin BS is engaged with the spring receiving portion after following the state in contact with the guide portion 12B of the contact support 12 by the biasing force of each coil spring SP1 with the tip of You can stop it. When the contact support 12 is further pressed against the spring accommodating portion 10Lb of the main body 10L against the urging force of the pressing spring SP2, the tips of the second portions 14Mb of the contact terminals 14Rai and 14Lai are It is separated from the surface of the stopper plate 16. Accordingly, the contact portion 14C of the first portion 14Ma of the contact terminals 14Rai and 14Lai is brought close to and in contact with the lead terminal DVa.

  In such a configuration, when the electrical component DV is inspected by the electrical component inspection socket 10, first, when the electrical component DV reaches the position immediately below the material handling unit 18 and the electrical component inspection socket 10, the tact drive conveyor 20 is stopped, and the material handling unit 18 and the electrical component inspection socket 10 are lowered to a predetermined position as shown in FIG. As a result, the lead terminal DVa of the electrical component DV is inserted into the recess 12D of the pressure receiving portion 12P of the contact support 12 in the electrical component inspection socket 10, and the end surface near the root of the lead terminal DVa is the pressure receiving portion 12P. It contacts the pressure receiving surface. At this time, the lead terminal DVa is arranged with a predetermined gap between the contact portions 14C of the first portions 14Ma of the contact terminals 14Rai and 14Lai facing each other. Further, the tips of the second portions 14 </ b> Mb of the contact terminals 14 </ b> Rai and 14 </ b> Lai are engaged with the surface of the stopper plate 16.

  Next, as shown in FIG. 4B, when the material handling portion 18 is further lowered against the urging force of the pressing spring SP2, the pressure receiving surface of the pressure receiving portion 12P of the contact support 12 becomes the cover member. As shown in FIG. 4C, it passes through the periphery of the opening 10UD of 10U and is pushed into the opening 10UD of the cover member 10U until the bottom surface of the contact support 12 abuts against the bottom surface of the main body 10L. It is. At that time, the stopper plate 16 follows the state in contact with the guide portion 12B of the contact support body 12 by the biasing force of each coil spring SP1 with the tips of the second portions 14Mb of the contact terminals 14Rai and 14Lai, When the head of the guide pin BS is engaged with the spring receiving portion, the stopper plate 16 is stopped at a predetermined position with a predetermined gap with respect to the guide portion 12B of the contact support 12. As a result, the tips of the second portions 14Mb of the contact terminals 14Rai and 14Lai are separated from the surface of the stopper plate 16, so that the contact portions 14C of the first portions 14Ma of the contact terminals 14Rai and 14Lai are respectively slit 12RSi, And it protrudes in the direction which mutually adjoins from slit 12LSi, and is contact | abutted to the outer peripheral part of lead terminal DVa. That is, when the pressing amount in the pressure receiving portion 12P of the contact support body 12 exceeds a predetermined value by the stopper plate 16 and the guide pin BS, the contact portion 14C reliably contacts the outer peripheral portion of the lead terminal DVa. The position of the portion 18 can be easily controlled, and even if the pushing amount is set to be relatively large, there is no possibility that the contact portion 14C contacts the outer peripheral portion of the lead terminal DVa undesirably and prematurely. That is, the stopper plate 16 and the guide pin BS form a means for preventing premature contact between the contact portion and the lead terminal DVa according to the amount of pressing of the contact support 12.

  At this time, the contact portion 14C abuts against the outer peripheral portion of the lead terminal DVa without coming into contact with the lead terminal DVa from a direction substantially orthogonal to the lead terminal DVa, so that there is no possibility that a scar due to the contact portion 14C remains on the lead terminal DVa.

  Therefore, the contact terminals 14Rai and 14Lai are electrically connected to the lead terminal DVa of the electrical component DV only by moving the contact portions 14C of the first portions 14Ma of the contact terminals 14Rai and 14Lai in the direction close to each other. It becomes. As a result, the time required for the inspection of the lead terminal DVa of the electrical component DV can be shortened.

  Subsequently, after completion of the predetermined inspection of the electrical component DV, as shown in FIG. 4A, the material handling unit 18 and the electrical component inspection socket 10 are moved away from the electrical component DV, and the electrical component Returned to a position just above DV. Then, the new electrical component DV is conveyed by the tact drive conveyor 20 to a position directly below the material handling unit 18 and the electrical component inspection socket 10.

The cover member 10'U is pushed into the opening 10'UD until it is in the same plane as the periphery of the 10'U opening 10'UD. As a result, the tips of the second portions 14Mb of the contact terminals 14Rai and 14Lai are separated from the inner peripheral edge of the opening end of the opening 10'UD of the cover member 10'U, so the first of the contact terminals 14Rai and 14Lai The contact portions 14C of the portion 14Ma protrude from the slits 12RSi and the slits 12LSi in directions close to each other, and come into contact with the outer peripheral portion of the lead terminal DVa.

  The slider 72 is formed of, for example, a resin material, and as shown in FIG. 10B, when the plurality of contact terminals 74Rai and 74Lai are close to the lead terminal DVa, the pressure receiving pressure that contacts the end face of the electrical component DV. It has a surface at one end. A central portion of the flat pressure receiving surface is provided with a recess having a cross-sectional shape smaller than the outer shape of the electrical component DV.

  Slits 72RSi and 72LSi (i = 1 to n, where n is a positive integer) are formed to face each other substantially parallel to the periphery of the recess. The slits 72RSi and 72LSi are each formed in a line along the long side with a predetermined interval. The adjacent slits 72RSi and 72LSi in each row are partitioned by a partition wall.

  In such a configuration, when the electric component DV is inspected by the electric component inspection socket, first, when the electric component DV reaches the position immediately below the material handling portion 18 and the electric component inspection socket, FIG. As shown in FIG. 2, the tact drive conveyor 20 is stopped, and the material handling unit 18 and the electrical component inspection socket are lowered to a predetermined position. As a result, the lead terminal DVa of the electrical component DV is inserted into the concave portion of the slider 72 in the electrical component inspection socket, and the end surface near the root of the lead terminal DVa is brought into contact with the pressure receiving surface of the slider 72. At this time, the lead terminal DVa is arranged with a predetermined gap between the contact portions 74C of the first portions 74Ma of the contact terminals 74Rai and 74Lai facing each other. Further, the tips of the second portions 74Mb of the contact terminals 74Rai and 74Lai are engaged with the bottoms of the slider 72 where the slits 72RSi and 72LSi are formed.

  Next, when the material handling part 18 is further lowered against the urging force of the pressing spring SP6, the pressure receiving surface of the slider 72 is formed on the opening 70D of the main body part 70 as shown in FIG. It is pushed into the opening 70D until it is in the same plane as the periphery. As a result, the tips of the second portions 74Mb of the contact terminals 74Rai and 74Lai are separated from the bottoms forming the slits 72RSi and 72LSi of the slider 72, so that the contact portions 74C of the first portions 74Ma of the contact terminals 74Rai and 74Lai are formed. , Project from the slit 72RSi and the slit 72LSi in a direction close to each other, and contact the outer peripheral portion of the lead terminal DVa. At that time, since the contact portion 74C abuts from the direction substantially orthogonal to the axis of the lead terminal DVa without rubbing against the outer peripheral portion of the lead terminal DVa, there is no possibility that a scar due to the contact portion 74C remains on the lead terminal DVa.

  Therefore, the contact terminals 74Rai and 74Lai are electrically connected to the lead terminal DVa of the electrical component DV only by moving the contact portion 74C of the first portion 74Ma of the contact terminals 74Rai and 74Lai in the direction close to each other. It becomes. As a result, the time required for the inspection of the lead terminal DVa of the electrical component DV can be shortened.

  Subsequently, after completion of the predetermined inspection of the electrical component DV, the material handling unit 18 and the electrical component inspection socket are moved away from the electrical component DV and returned to a position directly above the electrical component DV. Then, the new electric component DV is conveyed by the tact drive conveyor 20 to a position directly below the material handling unit 18 and the electric component inspection socket.

  In the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, the sixth embodiment, and the seventh embodiment of the electrical component inspection socket according to the present invention described above, the electrical component inspection is performed. The socket is fixed to the material handling part of the transfer robot, and the electric parts are supported by the drive conveyor, but not limited to such an example, for example, the electric parts are supported by the material handling part of the transfer robot, The electrical component may be inspected while the electrical component inspection socket is fixed to the base. In the fourth and fifth embodiments, for example, an electrical component is inspected by being attached to and detached from an electrical component inspection socket by a manual operation without using the transfer robot and the drive conveyor as described above. Of course, it is also good. Further, in the first to seventh embodiments of the electrical component inspection socket according to the present invention described above, the contact terminal support has a pair of contact terminals facing each other. For example, when the electrical component has a row of lead terminals, or when the electrical component is a substrate having a contact pad on one side, the contact terminal support is a pair of facing each other. It may have only one of the contact terminal rows of the contact terminal rows.
