[0003] [Patent Document 1] US Patent Application Publication No. 2003 / 0060073 Summary of the Invention [Problem to be solved by the invention]
[0004] In the electrical component sockets according to the prior art, the cover member rotates about a pivot shaft in the closing direction to press against the electrical component housed in the socket body, which can cause a downward force to be applied to the electrical component from the cover member. In such cases, when electrical testing of the electrical component is performed, the electrical component may shift sideways on the socket body, damaging the terminals of the electrical component, or the cover member may rub against the top surface of the electrical component, causing scratches on the top surface of the electrical component.
[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a socket for electrical components that can prevent damage to the terminals of electrical components and scratches on the top surface of the electrical components when conducting electrical tests on the electrical components. [Means for solving the problem]

FIGS. 10A to 10E are diagrams illustrating how the support portion 30 of the movable support member 28 presses down the cover member 32 as the lever member 46 rotates in the closing direction.
[0012] 1 to 6, electrical component socket 10 according to this embodiment is a device used for electrical testing, such as burn-in testing, of electrical components P, such as IC (Integrated Circuit) packages. Electrical component socket 10 is disposed on a wiring board (not shown) for testing, which is connected to a testing device (not shown). Electrical component socket 10 electrically connects each terminal (not shown) of electrical component P to each electrode (not shown) on the wiring board for testing.
[0013] Electrical component socket 10 includes socket body 12 that is rectangular in plan view and that accommodates electrical component P. Socket body 12 includes rectangular base plate 14 that is disposed on a wiring board for testing, and a pair of fixing frames 16 that are disposed on the upper surface of base plate 14, spaced apart in the front-to-rear direction, and extend in the left-to-right direction. Fixing frames 16 are disposed on both ends of the upper surface of base plate 14 in the front-to-rear direction. Fixing frames 16 may be connected at both ends in the left-to-right direction by connecting frame 18.
[0014] As shown in FIGS. 1 to 3 , the socket body 12 has a contact pin unit 20 provided in the center of the upper surface of the base plate 14. The contact pin unit 20 has a known configuration, for example, as disclosed in Japanese Patent Application Laid-Open No. 2017-37722. The contact pin unit 20 has a lower plate 22 provided in the center of the upper surface of the base plate 14 and an upper plate 24 provided above the lower plate 22. The contact pin unit 20 has a floating plate 26 provided above the upper plate 24 in an upwardly biased state. The floating plate 26 corresponds to an accommodating portion that accommodates an electric component P. In other words, the socket body 12 has the floating plate 26 as an accommodating portion that accommodates an electric component P. The floating plate 26 has a mounting surface 26f on which the electric component P is placed, and the mounting surface 26f is a horizontal plane.
[0015] The contact pin unit 20 has a plurality of contact pins (not shown) that electrically connect terminals (not shown) of the electrical component P with electrodes (not shown) of the wiring board for inspection. The plurality of contact pins are arranged in a matrix, and each contact pin is held in a state where it is inserted into a through-hole (not shown) formed in the lower plate 22, the upper plate 24, and the floating plate 26, respectively. The upper end of each contact pin is capable of contacting a terminal of the electrical component P, and the lower end of each contact pin is in contact with an electrode of the wiring board for inspection. Each contact pin is biased upward by a spring (not shown) that serves as a pin biasing portion.
[0016] 1 to 8, a pair of movable support members 28 are provided at one left-right end of each fixed frame 16 so as to be movable up and down. In other words, two pairs of movable support members 28 are provided at one left-right end of the socket body 12 so as to be movable up and down, and the two pairs of movable support members 28 are spaced apart in the front-rear direction. Each movable support member 28 has an annular (cylindrical) support portion 30 (see FIG. 10A).
[0017] The base end of a cover member 32, which presses against the electrical components P housed in the floating plate 26, is connected to the support portions 30 of the two pairs of movable support members 28 so as to be rotatable in the opening and closing direction. The cover member 32 rotates in the opening and closing direction around a rotation axis on the base end side. The cover member 32 is configured to switch between an upright position and a horizontally laid position by the rotational movement in the opening and closing direction. The rotation center of the cover member 32 coincides with the center of the support portions 30 of the two pairs of movable support members 28, and is displaced in the up and down direction by the vertical movement of the two pairs of movable support members 28. The cover member 32 is also biased in the opening direction by a cover biasing portion such as a spring.
[0018] 1, 2, 4, and 5, the cover member 32 has a rectangular frame-shaped cover member main body 34, and the base end side of the cover member main body 34 is connected to the support portions 30 (see FIG. 10A) of the two pairs of movable support members 28 so as to be rotatable in the opening and closing direction. An elongated hole 34h extending in the longitudinal direction of the cover member 32 is formed on the side of the cover member main body 34 near the tip. The cover member 32 also has a pressing member 36 that is disposed inside the cover member main body 34 and presses the electrical component P. The pressing member 36 is configured to be rotatable relative to the cover member main body 34 and displaceable in the up and down direction.
[0019] As shown in Figures 4 to 6 and 9B, an inverted U-shaped latch member 38 is provided on the tip side of the cover member main body 34 so as to be movable in the longitudinal direction of the cover member main body 34, and the latch member 38 is configured to be unable to be detached from the cover member main body 34. The latch member 38 has a pair of latch pins 40 that are spaced apart in the front-to-rear direction. Each latch pin 40 is engaged with an elongated hole 34h of the cover member main body 34 so as to be movable in the longitudinal direction of the cover member main body 34. In addition, a plurality of springs 42 (see Figure 6) are provided at appropriate positions on the cover member main body 34 as latch biasing portions that bias the latch member 38 toward the tip of the cover member main body 34.
[0020] 1 to 8, a rotation shaft (hinge shaft) 44 is rotatably provided at one left-right end of each fixed frame 16. In other words, a pair of rotation shafts 44 is rotatably provided at one left-right end of the socket body 12, and the pair of rotation shafts 44 are spaced apart in the front-rear direction. Each rotation shaft 44 is inserted into the inside of the support portion 30 (see FIG. 10A) of the pair of movable support members 28.
[0021] As shown in FIGS. 1 to 6 , the base end of an inverted U-shaped lever member 46 for pressing the cover member 32 is integrally connected to the pair of rotation shafts 44. In other words, the base end of the lever member 46 is provided at one left-right end of the socket body 12 so as to be rotatable in the opening and closing direction via the pair of rotation shafts 44. The lever member 46 rotates in the opening and closing direction around a rotation axis on the base end side. The rotation axis of the lever member 46 coincides with the axis of the rotation shafts 44 and is offset from the rotation axis of the cover member 32. The lever member 46 is configured to switch between an upright position and a reclined position by rotating in the opening and closing direction.
[0022] 1 to 3 and 9A, the base end of a link member 48 is connected to the other left-right end of each fixed frame 16 so as to be rotatable in the opening and closing direction via a pivot pin (hinge pin) 50. In other words, the base end of a pair of link members 48 is connected to the other left-right end of the socket body 12 so as to be rotatable in the opening and closing direction via the pivot pin 50. The pair of link members 48 are spaced apart in the front-rear direction, and each link member 48 extends in the left-right direction.
[0023] Each link member 48 has a hook-shaped locked portion 52, and each locked portion 52 is located closer to the base end than to the tip end of each link member 48. Furthermore, a spring 54 (see FIG. 9A) is provided at an appropriate position on the socket body 12 as a link biasing portion that biases each link member 48 in the opening direction.
[0024] 6 and 9A to 9E, by rotating the cover member 32 in the closing direction, each latch pin 40 as part of the cover member 32 climbs over each of the locked portions 52 against the biasing force of the spring 54. Then, after each latch pin 40 climbs over due to the rotation of the cover member 32 in the closing direction, it is locked to each of the locked portions 52 by the biasing force of the spring 54.
[0025] 7, 8, and 9A to 9H, socket 10 for electrical components includes pressing mechanism 56 as a first interlocking mechanism that presses the distal ends of paired link members 48 downward in response to the pivotal movement of lever member 46 in the closing direction. Specifically, a pair of brackets 58 is integrally provided with each pivot shaft 44. In other words, two pairs of brackets 58 are integrally provided with paired pivot shafts 44 on the proximal end side of lever member 46, and the two pairs of brackets 58 are spaced apart in the front-to-rear direction.
[0026] A pressure roller 60 that presses the tip end side of the link member 48 is rotatably mounted on each bracket 58. In other words, two pairs of pressure rollers 60 are rotatably mounted via brackets 58 on the base end side of the lever member 46, and the two pairs of pressure rollers 60 are spaced apart in the front-to-rear direction. The center of rotation of each pressure roller 60 is eccentric with respect to the rotation axis of the lever member 46 (the axis of the rotation shaft 44). Each pressure roller 60 rotates integrally with the lever member 46 around the rotation axis of the lever member 46.
[0027] 9F to 9H , the pressing mechanism 56 is interlocked with the pivotal movement of the lever member 46 in the closing direction, causing the locked portions 52 of each link member 48 to press the cover member 32 downward, perpendicular to the mounting surface 26f of the floating plate 26. In other words, the pressing mechanism 56 is interlocked with the pivotal movement of the lever member 46 in the closing direction, causing the cover member 32 to move downward, perpendicular to the mounting surface 26f of the floating plate 26, via the locked portions 52 of each link member 48.
[0028] Each latch pin 40, lever member 46, each link member 48, and pressing mechanism 56 constitute a double lever that increases the operating force applied to the lever member 46 and transmits it from the locked portion 52 of each link member 48 to the cover member 32. The double lever refers to one lever with the pivot shaft 44 as the fulcrum, the tip side of the lever member 46 as the point of application, and the pressing portion of the pressure roller 60 as the point of force, and another lever with the pivot pin 50 as the fulcrum, the pressing portion of the pressure roller 60 as the point of application, and the locked portion 52 as the point of force. The double lever is a second-class lever.
[0029] 9H, when the lever member 46 is closed, the biasing force of each spring 54 causes the pressure rollers 60 to act on the lever member 46 in the closing direction. This allows the lever member 46 to be stably maintained in the closed state.
[0030] As shown in Figures 7, 8, and 10A to 10E, socket 10 for electrical components includes cam mechanisms 62 as a second interlocking mechanism that moves two pairs of movable support members 28 downward in response to the pivotal movement of lever member 46 in the closing direction. Specifically, each movable support member 28 is provided with a hole-shaped cam guide 64. A pair of cams 66 that engage with the corresponding cam guide 64 is integrally formed with each pivot shaft 44. In other words, two pairs of cams 66 are integrally formed with the base end of lever member 46 via a pair of pivot shafts 44, and the two pairs of cams 66 are spaced apart in the front-to-rear direction. Each cam 66 rotates integrally with lever member 46 about the pivot axis of lever member 46.
[0031] 10A to 10E, the cam mechanism 62 is interlocked by the pivotal movement of the lever member 46 in the closing direction, causing the support portions 30 of each movable support member 28 to press the cover member 32 downward, perpendicular to the mounting surface 26f of the floating plate 26. In other words, the cam mechanism 62 is interlocked by the pivotal movement of the lever member 46 in the closing direction, causing the cover member 32 to move downward, perpendicular to the mounting surface 26f of the floating plate 26, via the support portions 30 of each movable support member 28.
[0032] Here, the amount of downward movement of the support portion 30 of each movable support member 28 corresponds to the amount of change in the distance from the pivot shaft 44 to the pressing portion of the cam 66 (the portion that contacts the cam guide 64). In other words, the amount α by which the cover member 32 is pressed down by the support portion 30 of each movable support member 28 changes from d1 to d4 corresponding to the amount of change in the distance from the pivot shaft 44 to the pressing portion of the cam 66. Furthermore, the amount by which the cover member 32 is pressed down by the support portion 30 of each movable support member 28 after the cover member 32 has switched to its horizontally laid-down position is the same as the amount by which the cover member 32 is pressed down by the locked portion 52 of each link member 48. For example, when the amount α by which the cover member 32 is pressed down by the support portion 30 of each movable support member 28 is d1, d2, or d3, the amount by which the cover member 32 is pressed down by the support portion 30 of each movable support member 28 will also be d1, d2, or d3, respectively.
[0033] The lever member 46 and the cam mechanism 62 constitute a lever that increases the operating force applied to the lever member 46 and transmits it from the support portion 30 of each movable support member 28 to the cover member 32. The lever has the rotation shaft 44 as its fulcrum, the tip side of the lever member 46 as its point of application, and the pressing portion of the cam 66 (the portion that comes into contact with the cam guide 64) as its point of application, and is a second-class lever.
[0034] 9H and 10E, after the cover member 32 has switched to the horizontally laid position, the positions of the locked portions 52 of each link member 48 and the support portions 30 of each movable support portion 28 are asymmetric with respect to the longitudinal center position of the cover member 32. The distance between the positions of the locked portions 52 of each link member 48 and the longitudinal center position of the cover member 32 is shorter than the distance between the positions of the support portions 30 of each movable support portion 28 and the longitudinal center position of the cover member 32. The magnification of the increase in operating force due to the double lever is smaller than the magnification of the increase in operating force due to the lever member 46. This allows the operating force applied to the lever member 46 to be efficiently transmitted to the cover member 32.
[0035] Next, the operation of using the electrical component socket 10 according to this embodiment will be described.
[0036] As shown in Fig. 1, an electric component P is accommodated in floating plate 26, which serves as an accommodating portion of socket body 12. Next, as shown in Figs. 9A to 9F, cover member 32 is rotated in the closing direction, causing cover member 32 to switch from an upright position to a horizontally laid position. While cover member 32 is switching to the horizontally laid position (immediately before), each latch pin 40 overcomes each locked portion 52 against the biasing force of spring 54, and then is engaged with each locked portion 52 by the biasing force of spring 54.
[0037] 9F to 9H, the lever member 46 is rotated in the closing direction to activate the pressing mechanism 56, causing the locked portions 52 of the link members 48 to press the cover member 32 downward. Furthermore, as shown in FIGS. 10A to 10E, the lever member 46 is rotated in the closing direction to activate the cam mechanism 62, causing the support portions 30 of the movable support members 28 to press the cover member 32 downward, which is in a horizontally laid position. This causes the pressing members 36 of the cover member 32 to press the electric component P housed in the socket body 12, electrically connecting the terminals of the electric component P to the electrodes of the wiring board for testing via the contact pins of the contact pin unit 20. As a result, electrical testing, such as a burn-in test, of the electric component P can be performed by the testing device.
[0038] According to the configuration of the electrical component socket 10 of this embodiment, as described above, pivoting the cover member 32 in the closing direction causes the latch pins 40, which are part of the cover member 32, to engage with the respective locked portions 52. Furthermore, pivoting the lever member 46 in the closing direction interlocks the pressing mechanism 56 and the cam mechanism 62, causing the locked portions 52 of the link members 48 and the support portions 30 of the movable support members 28 to press the cover member 32 downward. Therefore, when the cover member 32 presses the electrical component P, the force applied from the cover member 32 to the electrical component P is downward, rather than diagonally downward. This prevents the electrical component P from shifting laterally on the socket body 12 and the cover member 32 from scraping the top surface of the electrical component P.
[0039] Therefore, with the electrical component socket 10 according to this embodiment, damage to the terminals of the electrical component P and scratches on the top surface of the electrical component P can be reduced when an electrical test is performed on the electrical component P.
[0040] Furthermore, with the configuration of electrical component socket 10 according to this embodiment, as described above, pivoting lever member 46 in the closing direction causes locked portions 52 of each link member 48 and support portions 30 of each movable support member 28 to press down on cover member 32. Therefore, by simply pivoting one lever member 46, cover member 32 in a horizontally laid position can be stably moved downward.
[0041] Therefore, according to the electrical component socket 10 of this embodiment, the operability (handling ease) of the electrical component socket 10 can be improved.
[0042] Furthermore, as described above, after the cover member 32 has switched to the horizontally laid position, the amount by which the support portions 30 of each movable support member 28 press down on the cover member 32 is the same as the amount by which the locked portions 52 of each link member 48 press down on the cover member 32. Therefore, the cover member 32 in the horizontally laid position can be moved downward more stably.
[0043] Therefore, according to the electrical component socket 10 of this embodiment, the operability of the electrical component socket 10 can be further improved.
[0044] Furthermore, with the configuration of electrical component socket 10 according to this embodiment, as described above, pivoting cover member 32 in the closing direction causes each latch pin 40, which is part of cover member 32, to engage with each locked portion 52. Furthermore, a pressure roller 60 that presses against the tip end of link member 48 is rotatably provided on the base end of lever member 46, and the center of rotation of pressure roller 60 is eccentric with respect to the rotation axis of lever member 46. Therefore, even if the operating force of lever member 46 is small, the double lever mechanism can be used to generate a sufficient downward force (depressing force) on locked portions 52 of link member 48. In particular, when locked portions 52 are located closer to the base end than the tip of each link member 48, the leverage effect with locked portions 52 as the force point can be fully exerted.
[0045] Therefore, according to the electrical component socket 10 of this embodiment, the operability of the electrical component socket 10 can be further improved.
[0046] Furthermore, according to the configuration of electrical component socket 10 of this embodiment, as described above, each movable support member 28 is provided with cam guide 64, and cam 66 that engages with cam guide 64 is integrally provided on the base end side of lever member 46. Therefore, even if the operating force of lever member 46 is small, a sufficiently large downward force (depressing force) can be generated on support portion 30 of movable support member 28 using the leverage.
[0047] Therefore, according to the electrical component socket 10 of this embodiment, the operability of the electrical component socket 10 can be further improved.
[0048] Although the present embodiment has been specifically described above, the present invention is not limited to the specific embodiment described above. Various modifications and changes to the specific examples described in the above embodiment are possible within the scope of the gist of the present invention as defined in the claims. [Industrial Applicability]
