Description

  The present invention relates to an electronic component socket used when conducting a continuity test or characteristic measurement of an electronic component.

  Conventionally, sockets for BGA type ICs have been disclosed as electronic component sockets (hereinafter also simply referred to as “sockets”) used when electrical measurement of electronic components such as ICs is performed. For example, Patent Document 1 discloses a configuration for preventing a socket contact from sticking to a solder ball of an IC package.

  In this socket, the attached contact of the socket and the pad of the IC package can be forcibly and easily peeled off in a series of operations for taking out the IC package from the socket.

  Patent Document 2 discloses a configuration in which a slide plate is movably provided with respect to a socket body, and the movable elastic piece of the contact pin is elastically deformed by moving the slide plate. In this socket, the contact portion provided at the tip of the elastic piece is displaced so as to be separated from the side surface portion of the solder ball.

  In this socket, it is possible to prevent the contact pin contact portion from sticking to the solder ball, and to remove the electrical component from the electrical component socket without any force.

  In recent years, the pitch between the external connection terminals has been narrowed due to the miniaturization of the electronic component, and a highly accurate fitting between the electronic component and the socket is required. For example, when a connector terminal mounted on a flexible substrate is brought into contact with a contact portion of a socket, a guide corresponding to the outer dimension of the connector is provided on the socket side. Then, the electronic component is mounted on the base of the socket, and the connector is fitted into the guide when the cover of the socket is closed, so that the terminal and the contact portion are aligned.

  However, when the electronic component is small and high accuracy is required for alignment between the connector terminal and the socket contact portion, the fitting tolerance between the guide and the connector becomes very small. As a result, the guide and the connector are tightly fitted to each other, and when the cover is opened after the measurement, the connector is not detached from the guide and an electronic component is likely to stick to the cover side.

  An object of this invention is to provide the socket for electronic components which can prevent adhesion of the electronic component at the time of opening the cover of a socket.

  In order to solve the above-described problems, an electronic component socket according to the present invention includes a base having a portion on which an electronic component to be measured is placed, a cover that can be opened and closed with respect to the base, and a base that is closed by closing the cover. A contact portion that comes into contact with a terminal of the electronic component placed on the device, a contact portion that is disposed, a guide portion that is fitted to the electronic component by closing the cover, and a shaft that is interlocked with the opening and closing operation of the cover. The shaft does not contact the electronic component from the closed position to the first position where the cover is slightly opened, and contacts the electronic component while the cover is opened from the first position to the second position. And the guide part are removed, and the cover is further opened from the second position so as to be separated from the electronic component.

  According to such a configuration, when the cover is closed, the shaft and the electronic component do not contact each other, and a reliable contact between the terminal of the electronic component and the contact portion is performed. Further, while the cover is opened from the first position to the second position, the electronic component is pressed by the shaft, the fitting between the guide portion and the electronic component is released, and only the cover is opened. This can prevent the electronic component from sticking to the cover side.

  In the electronic component socket according to the present invention, the cover is provided so as to be rotated via a hinge provided on the base, and the guide portion is moved along a circular orbit by the rotation of the cover and is fitted to the electronic component. It may come to be.

  When the cover is provided so as to rotate, there is a high possibility that the electronic component is obliquely fitted with the guide portion along the circular orbit of the cover. Even if such fitting is performed, when the cover is opened, the electronic component can be pressed by the shaft to prevent the electronic component from sticking.

  In the socket for electronic parts of the present invention, the shaft may be attached to a shaft holder provided so as to be rotatable about the axis of the hinge. Thereby, a shaft and a cover can be comprised coaxially.

  In the electronic component socket according to the present invention, the shaft holder has a convex portion protruding toward the cover, the shaft holder is urged away from the cover, and the convex portion is formed when the cover is opened to the second position. The cover is pressed by the cover when opened from the second position and rotated in the opening direction of the cover, and the shaft is rotated in the opening direction of the cover by the rotation of the convex portion. May be. Accordingly, when the cover is opened, the position of the shaft is maintained by the urging force applied to the shaft holder, and the electronic component can be pulled away from the guide portion in contact with the electronic component. Further, when the cover is opened more than the second position, the convex portion is pressed by the cover and the shaft can be opened together with the cover.

  In the electronic component socket according to the present invention, the base has a stopper portion that restricts the shaft holder from rotating in the opening direction of the cover, and the shaft holder is urged away from the base to close the cover. The shaft holder is pushed in by the cover from the first position to the closing position, and when the cover is opened, the shaft or the shaft holder comes into contact with the stopper when the cover is opened to the second position. When opening, the cover may be opened with the shaft remaining. As a result, when the cover is opened, the shaft is lifted by the biasing force applied to the shaft holder, and the electronic component can be pulled away from the guide portion in contact with the electronic component. Moreover, when the cover is opened from the second position, the shaft or the shaft holder comes into contact with the stopper portion, and only the cover can be opened while leaving the shaft.

  In the electronic component socket according to the present invention, the base may include a first recess for mounting a part of the element module in the electronic component and a second recess for mounting a part of the substrate on which the element module is mounted. Good. Thereby, an element module is arrange | positioned inside a 1st recessed part, a board | substrate is arrange | positioned inside a 2nd recessed part, and each positioning is performed.

  In the electronic component socket according to the present invention, the contact portion may have a plurality of contact pins, and the pitch between the contact pins adjacent to each other may be 0.5 mm or less. With such a size, even with a small electronic component, high-precision contact and reliable sticking prevention can be realized.

  In the socket for electronic components of the present invention, the contact portion may have a contact sheet in which conductive particles are embedded in a columnar shape in an insulating member. Thereby, the soft contact with the electroconductive particle of a contact sheet and the terminal of an electronic component, and reliable sticking prevention are realizable.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same members are denoted by the same reference numerals, and the description of the members once described is omitted as appropriate.

(First embodiment)
FIG. 1 is a perspective view illustrating a state in which the electronic component socket according to the first embodiment is opened.
FIG. 2 is an enlarged view of the electronic component socket according to the first embodiment.
FIG. 3 is a perspective view illustrating a state in which the electronic component socket according to the first embodiment is closed.
The electronic component socket 1 according to the present embodiment is a component for mounting the electronic component 100 to be measured and obtaining electrical contact with the terminals of the electronic component 100.

  The electronic component socket 1 includes a base 10, a cover 20, a contact pin 30, a guide portion 40, and a shaft 50. The base 10 has a portion on which the electronic component 100 is mounted. The electronic component 100 is disposed inside the recess 101 of the base 10. The shape of the recess 101 is provided in accordance with the shape of the electronic component 100. By positioning the electronic component 100 in the recess 101, the electronic component 100 is aligned on the base 10.

  Here, the electronic component 100 to be measured by the electronic component socket 1 of the present embodiment includes a substrate (for example, a flexible substrate) 110, an element module 120 mounted on the substrate 110, and a substrate 110. And a connected connector 130. A wiring pattern is formed on the substrate 110, and energization is performed between the element module 120 and the connector 130. Therefore, in the electronic component socket 1 of the present embodiment, electrical contact with the element module 120 can be obtained by bringing the contact pins 30 into contact with the terminals of the connector 130.

  When such an electronic component 100 is a measurement target, the recess 101 includes a first recess 101a on which the element module 120 is placed and a second recess 101b on which the substrate 110 is placed. In the first recess 101a, a recess having a size matching a part of the outer shape of the element module 120 is provided, and the position of the element module 120 can be aligned. In addition, in the second recess 101b, a recess having a size matching a part of the outer shape of the substrate 110 is provided, so that the portion of the substrate 110 can be aligned.

  The cover 20 is provided so that it can be opened and closed with respect to the base 10. The cover 20 is attached via a hinge 150 provided on the base 10 and is provided so as to rotate with respect to the base 10. A tube 155 of the hinge 150 is provided on the base 10 side, and a tube 156 of the hinge 150 is provided on the cover 20 side. A shaft 151 of the hinge 150 is provided so as to pass through these tubes 155 and 156. As a result, the cover 20 can rotate along a circular orbit about the shaft 151.

  The cover 20 is provided with a latch 25. The state where the cover 20 is closed is maintained by hooking the latch 25 on the base 10 with the cover 20 closed. The cover 20 is urged in the opening direction by a spring. Therefore, by removing the latch 25, the cover 20 is opened by the biasing force of the spring.

  The contact pin 30 is an example of a contact portion. The contact pin 30 is a needle-like electrode that comes into contact with the terminal of the electronic component 100 (the terminal of the connector 130 in this embodiment) placed on the base 10 by closing the cover 20. A plurality of contact pins 30 are provided corresponding to the terminals of the connector 130. The contact pin 30 is suspended from the cover 20 and is inserted into the connector 130 of the electronic component 100 placed on the base 10 when the cover 20 is closed, and comes into contact with the terminal of the connector 130. .

  For example, when a plurality of contact pins 30 are provided, the pitch between the contact pins 30 adjacent to each other is 0.5 mm or less. Moreover, the diameter of the contact pin 30 is 0.4 mm or less. As described above, the electronic component socket 1 according to the present embodiment includes the contact pins 30 that can contact the terminals of the very small connector 130. That is, the electronic component socket 1 of the present embodiment can correspond to the electronic component 100 with a pitch of about 0.3 mm or less.

  The guide part 40 includes a through hole 41 that allows the contact pin 30 to pass therethrough. The guide portion 40 has a recess that is fitted to the electronic component 100 by closing the cover 20. In the present embodiment, when the cover 20 is closed, the connector 130 is fitted into the concave portion of the guide portion 40, and the terminal of the connector 130 and the contact pin 30 are aligned. When the cover 20 is further closed, the guide portion 40 is pushed. When the guide part 40 is pushed in, the contact pin 30 is exposed from the through hole 41, and the terminal of the connector 130 and the contact pin 30 come into contact with each other.

  That is, the shape of the concave portion of the guide portion 40 is provided corresponding to the outer shape of the connector 130, and the connector 130 is positioned by fitting the concave portion and the outer shape of the connector 130. When the connector 130 is fitted into the guide portion 40 and positioned, the contact pin 30 exposed from the through hole 41 of the guide portion 40 and the terminal of the connector 130 are aligned.

  For example, the fitting tolerance when the center of the concave portion of the guide portion 40 is aligned with the center of the connector 130 is about 1/100 mm or more and 3/100 mm or less on one side. By fitting the connector 130 into the concave portion of the guide portion 40, the contact pin 30 and the terminal of the connector 130 can be accurately aligned even with a small electronic component 100 having a narrow pitch of about 0.3 mm or less. A reliable contact with is made.

  The shaft 50 is provided in conjunction with the opening / closing operation of the cover 20. The shaft 50 plays a role of reliably pulling the connector 130 fitted to the guide portion 40 away from the guide portion 40 when the cover 20 is opened.

  As described above, in order to obtain contact between the very small and narrow-pitch connector 130 and the contact pin 30, it is necessary to reduce the fitting tolerance between the concave portion of the guide portion 40 and the connector 130. For this reason, if the position of the guide part 40 and the connector 130 is slightly misaligned, or if the connector 130 slightly enters the guide part 40, the guide part 40 and the connector 130 are tightly fitted. In the electronic component socket 1 according to this embodiment, the connector 130 tightly fitted to the guide portion 40 can be reliably pulled apart by the operation of the shaft 50. The operation of the shaft 50 will be described later.

  The shaft 50 is attached to a shaft holder 51 provided so as to be rotatable about an axis 151 of the hinge 150. A spring 52 is provided between the shaft holder 51 and the cover 20 to urge the shaft holder 51 in a direction away from the cover 20.

  The shaft holder 51 has a convex portion 51a that protrudes toward the cover 20. The convex portion 51a contacts the end portion of the cover 20 when the cover 20 is opened more than a predetermined position. When the end portion of the cover 20 abuts on the convex portion 51a, when the cover 20 is opened more than that position, the convex portion 51a is pressed by the end portion of the cover 20, and the shaft holder 51 is rotated in the direction in which the cover 20 opens. . By rotation of the shaft holder 51, the shaft 50 is rotated in the opening direction of the cover 20 in conjunction with the cover 20.

Next, the operation of the shaft 50 interlocked with the cover 20 will be described.
FIG. 4A to FIG. 5B are partial cross-sectional views for explaining the operation when closing the cover.
First, as shown in FIG. 4A, the electronic component 100 is placed in the concave portion 101 of the base 10. At this time, the element module 120 is positioned by being disposed in the first recess 101a, and the substrate 110 is positioned by being disposed in the second recess 101b. However, since the connector 130 is mounted on the board 110, the position of the connector 130 with respect to the base 10 depends on the accuracy of the mounting position on the board 110.

  Next, the cover 20 is closed with the electronic component 100 placed on the base 10. The cover 20 is closed so as to rotate about the shaft 151 of the hinge 150. Further, the shaft holder 51 and the shaft 50 are also rotated in conjunction with the rotation of the cover 20.

  As shown in FIG. 4B, when the cover 20 is closed, the lower surface of the shaft holder 51 that rotates in conjunction with the base 10 comes into contact with the base 10 and stops there. When the cover 20 is further closed in this state, the cover 20 is closed while compressing the spring 52.

  As shown in FIG. 5A, when the cover 20 is further closed, the guide portion 40 is put on the connector 130 of the electronic component 100. Then, the connector 130 is fitted into the concave portion of the guide portion 40.

  FIG. 5B shows a state where the cover 20 is completely closed. By closing the cover 20, the connector 130 is fitted in the concave portion of the guide portion 40, and when the cover 20 is further pressed to close, the guide portion 40 is pushed. Then, the contact pin 30 protrudes from the through hole 41 of the guide portion 40. As a result, the contact pin 30 comes into contact with the terminal of the connector 130.

  That is, the connector 130 is fitted into the concave portion of the guide portion 40, whereby the guide portion 40 and the connector 130 are aligned. In this state, the contact pin 30 protrudes from the through hole 41, so that the contact pin 30 and the terminal of the connector 130 are accurately contacted. When the cover 20 is fixed to the base 10 by the latch 25, the contact state between the contact pin 30 and the terminal of the connector 130 is maintained. In this state, electrical measurement of the electronic component 100 is performed.

FIGS. 6A to 7B are partial cross-sectional views for explaining the operation when the cover is opened.
First, as shown in FIG. 6A, when the latch 25 is removed and the cover 20 is slightly opened, the positions of the shaft holder 51 and the shaft 50 are kept unchanged by the biasing force of the spring 52, and only the cover 20 starts to open. Here, when the connector 130 is fitted in the recess of the guide part 40, the connector 130 fitted in the guide part 40 is attached together with the opening of the cover 20.

  Next, as shown in FIG. 6B, when the cover 20 is further opened and the connector 130 is lifted, the shaft 50 and the substrate 110 at the same position are brought into contact with each other by the urging force of the spring 52. Here, the position of the cover 20 when the shaft 50 and the electronic component 100 (substrate 110) are in contact with each other is referred to as a “first position”.

  Next, as illustrated in FIG. 7A, when the cover 20 is further opened, the cover 20 is opened while the substrate 110 is being pressed by the shaft 50. As the cover 20 opens, the guide portion 40 also rises, so that the connector 130 is detached from the guide portion 40. That is, since the guide part 40 is raised while the substrate 110 is pressed by the shaft 50, the connector 130 fitted in the guide part 40 is removed from the guide part 40.

  Next, as shown in FIG. 7B, when the cover 20 is further opened, the end portion of the cover 20 comes into contact with the convex portion 51 a of the shaft holder 51. Here, the position of the cover 20 when the cover 20 is opened from the first position and the end portion of the cover 20 and the convex portion 51a are in contact with each other is referred to as a “second position”.

  And by opening the cover 20 rather than the 2nd position, the convex part 51a is pressed by the edge part of the cover 20, and rotates to the direction which the cover 20 opens. The shaft 50 is rotated in the opening direction of the cover 20 by the rotation of the convex portion 51a. That is, the shaft 50 is opened together with the cover 20.

  Such an operation of the shaft 50 prevents the electronic component 100 from sticking when the cover 20 is opened.

  The sticking of the electronic component 100 is more likely to occur due to a decrease in fitting tolerance between the guide portion 40 and the connector 130 as the connector 130 becomes smaller and narrower in pitch. In addition, when a flexible substrate is used as the substrate 110, the flexible substrate often bends when the guide portion 40 and the connector 130 are fitted, and the guide portion 40 and the connector 130 are caused by the tension caused by the bend. It will be a tight fit. Furthermore, when the cover 20 is provided so as to rotate, the connector 130 and the guide portion 40 are fitted obliquely along the circular orbit of the cover 20. Therefore, when the connector 130 is tightly fitted to the guide portion 40, the connector 130 is lifted while being fitted to the guide portion 40 when the cover 20 is opened, and the electronic component 100 is stuck to the cover 20. Will occur.

  In the electronic component socket 1 of the present embodiment, even when such a tight fitting between the guide portion 40 and the connector 130 occurs, the fitting between the guide portion 40 and the connector 130 is performed when the cover 50 is opened. The cover 20 can be opened only by the operation described above. This can prevent the electronic component 100 from sticking to the cover 20 side. In addition, since the shaft 50 opens together with the cover 20 after the electronic component 100 is removed, the shaft 50 does not interfere with the removal of the electronic component 100 from the base 10.

(Second Embodiment)
FIG. 8 is a perspective view illustrating a state in which the electronic component socket according to the second embodiment is opened.
FIG. 9 is an enlarged view of the electronic component socket according to the second embodiment.
FIG. 10 is a perspective view illustrating a state in which the electronic component socket according to the second embodiment is closed.
Similar to the electronic component socket 1 according to the first embodiment, the electronic component socket 1B according to the second embodiment mounts the electronic component 100 to be measured, and makes electrical contact with the terminals of the electronic component 100. It is a part for obtaining. For convenience of explanation, the electronic component 100 is not shown in FIGS. 8 to 10, but is disposed inside the concave portion 101 of the base 10 as in the electronic component socket 1 according to the first embodiment.

  In the electronic component socket 1B, the contact pin 30 and the guide portion 40 are provided on the base 10 side. As a result, the electronic component 100 is disposed in the recess 101 of the base 10 so that the connector 130 faces downward (to the base 10 side) with respect to the substrate 110.

  The base 10 is provided with a stopper portion 15. The stopper portion 15 serves to regulate the rotation of the shaft holder 51 in the opening direction of the cover 20. That is. The shaft holder 51 that rotates in conjunction with the opening of the cover 20 is stopped at the position of the stopper portion 15 and is not further opened.

  The shaft holder 51 is biased in a direction away from the base 10 by a spring 53. When the cover 20 is closed, the shaft holder 51 is pressed by the lower end of the cover 20 to overcome the urging force of the spring 53 and push down the shaft holder 51 and the shaft 50. On the other hand, when opening the cover 20, the shaft holder 51 and the shaft 50 are lifted by the biasing force of the spring 53. Here, even if the shaft 50 is lifted, it is stopped at the position of the stopper portion 15.

  A pusher 26 that protrudes downward is provided on the lower end surface of the cover 20. The pusher 26 pushes down the substrate 110 by closing the cover 20. As a result, the connector 130 disposed downward with respect to the substrate 110 is pushed down toward the guide portion 40 on the base 10 side. The connector 130 is fitted into the concave portion of the guide portion 40 from above, so that the terminals of the connector 130 and the contact pins 30 are aligned. When the cover 20 is further closed, the guide portion 40 is pushed. When the guide part 40 is pushed in, the contact pin 30 is exposed from the through hole 41, and the terminal of the connector 130 and the contact pin 30 come into contact with each other.

  When the cover 20 is opened, the shaft 50 and the electronic component 100 come into contact with each other when the cover 20 is opened to the first position. When the cover 20 is opened from the second position, the electronic component 100 is pushed up by the shaft 50 and the connector 130 is removed from the guide portion 40. Further, when the cover 20 is opened to the second position, the shaft 50 or the shaft holder 51 comes into contact with the stopper portion 15, and when opening from the second position, only the cover 20 is opened leaving the shaft 50.

Next, the operation of the shaft 50 interlocked with the cover 20 will be described.
Fig.11 (a)-FIG.12 (b) are partial sectional drawings explaining the operation | movement at the time of closing a cover.
First, as shown in FIG. 11A, the electronic component 100 is placed in the recess 101 of the base 10. At this time, the element module 120 and the connector 130 are arranged so as to protrude downward (to the base 10 side) with respect to the substrate 110. The element module 120 is positioned by being disposed in the first recess 101a, and the substrate 110 is positioned by being disposed in the second recess 101b. However, since the connector 130 is mounted on the board 110, the position of the connector 130 with respect to the base 10 depends on the accuracy of the mounting position on the board 110.

  Next, as illustrated in FIG. 11B, the cover 20 is closed with the electronic component 100 placed on the base 10. The cover 20 is closed so as to rotate about the shaft 151 of the hinge 150.

  Next, as shown in FIG. 12A, when the cover 20 is further closed, the lower end surface of the cover 20 comes into contact with the upper end surface of the shaft holder 51 and overcomes the urging force of the spring 53. Press down.

  Next, as shown in FIG. 12B, when the cover 20 is further closed, the pusher 26 protruding downward from the cover 20 contacts the substrate 110 and pushes down the substrate 110. Accordingly, the connector 130 disposed downward with respect to the substrate 110 is fitted into the recess of the guide portion 40 on the base 10 side. By fitting the connector 130 into the recess of the guide portion 40, the terminal of the connector 130 and the contact pin 30 are aligned.

  When the cover 20 is further closed, the guide portion 40 is pushed in, and the contact pin 30 is exposed from the through hole 41 of the guide portion 40. Thereby, the terminal of the connector 130 and the contact pin 30 come into contact. When the cover 20 is fixed to the base 10 by the latch 25, the contact between the contact pin 30 and the terminal of the connector 130 is maintained. In this state, electrical measurement of the electronic component 100 is performed.

FIG. 13A to FIG. 14B are partial cross-sectional views for explaining the operation when the cover is opened.
First, as shown in FIGS. 13A to 13B, when the latch 25 is removed and the cover 20 is slightly opened, the shaft holder 51 and the shaft 50 are rotated by the biasing force of the spring 53. Rotate in the same direction. Here, if the connector 130 is fitted in the recess of the guide portion 40, the connector 130 remains fitted in the guide portion 40 even when the cover 20 is opened.

  Next, when the cover 20 is further opened, the shaft 50 comes into contact with the lower surface of the substrate 110. Next, as shown in FIG. 14A, when the cover 20 is further opened, the shaft 50 is further pushed up by the urging force of the spring 53, and the substrate 110 is lifted from below. Thereby, the connector 130 fitted in the guide part 40 is removed from the guide part 40.

  Next, as shown in FIG. 14B, when the cover 20 is further opened, the shaft 50 (shaft holder 51) lifted by the urging force of the spring 53 hits the stopper portion 15 and no longer rotates. . On the other hand, the cover 20 can be further opened from the position. The shaft 50 stops at the position of the stopper portion 15, and the electronic component 100 can be easily removed by opening only the cover 20.

  As described above, according to the electronic component sockets 1, 1 </ b> B according to the embodiment, the electronic component 100 can be prevented from sticking by the operation of the shaft 50 when the cover 20 is opened.

  In addition, although this embodiment and its specific example were demonstrated above, this invention is not limited to these examples. For example, an example in which the electronic component 100 to be measured includes the substrate 110, the element module 120, and the connector 130 has been described. However, the electronic component 100 having a configuration other than the above is applicable. In the above embodiment, the contact pin 30 has a so-called inner spring type structure in which a coil spring is disposed in a cylindrical casing, but the present invention is not limited to this. An outer spring type may be used, or a combination of leaf springs may be used. Furthermore, a contact sheet may be used as the contact portion. The contact sheet is an anisotropic conductive sheet in which conductive particles are embedded in columns in an insulating member (for example, silicone rubber). With such a contact sheet, soft contact between the conductive particles and the terminals of the electronic component 100 and reliable sticking prevention can be realized. Further, those in which those skilled in the art appropriately added, deleted, and changed the design of the above-described embodiments or specific examples thereof, and combinations of the features of each embodiment as appropriate are also included in the present invention. As long as the gist is provided, it is included in the scope of the present invention.
