Description

Technical Field

[0001] This utility model relates to a test socket, and more specifically, to a test socket including a fixing device capable of detachably fixing an object while sliding. Background Technology

[0002] To ensure the quality of semiconductor devices, additional tests are performed in addition to inspection using integrated circuit (IC) testers. Specifically, semiconductor devices, separated from the wafer and completed as a product, are mounted onto motherboards or expansion cards. Then, before the motherboards or expansion cards are shipped, the semiconductor devices are re-inspected through, for example, operational verification tests. This inspection performed in the mounted state is called System-Level Testing (SLIT).

[0003] With recent advancements in semiconductor technology, the spacing between terminals in semiconductor devices has decreased, and high-speed semiconductors have become mainstream. Furthermore, system-level testing is frequently performed to ensure testing reliability.

[0004] In system-level testing, the device under test (DUT), such as a semiconductor device, is electrically connected to the test equipment. A predetermined electrical signal is then applied to the DUT from the test equipment, and the output signal from the DUT is received to determine if the DUT has defects.

[0005] The device under test (DUT) does not directly contact the test equipment. Instead, the DUT is electrically connected to the test equipment via a test socket. When a signal is applied from the test equipment, the signal is transmitted to the DUT through the test socket. The response signal output from the DUT is then transmitted back to the test equipment through the test socket.

[0006] Test sockets used for system-level testing are equipped with securing devices, such as latches. The device under test (DUT) can be detachably secured by these devices.

[0007] Traditional fastening devices have a drawback: due to the length of the latch, they are difficult to apply to low-profile objects. Utility Model Content

[0008] The present invention aims to solve the above problems. The technical objective of the present invention is to provide a test socket suitable for low-profile objects.

[0009] Solution to the problem

Hereinafter, Figure 5 The object 170 shown can be described as the device under test.

[0108] According to a first embodiment of the present invention, a test socket 100 accommodates a device under test. The device under test accommodated in the test socket 100 is electrically connected to a test device.

[0109] The test socket 100 includes a socket body 110 and a fixing device 120.

[0110] The socket body 110 has a four-corner plate shape, and a four-corner receiving portion 111 is provided in the center of the socket body 110. The receiving portion 111 is a through hole formed in the vertical direction VD, and has a shape corresponding to the shape of the device under test to accommodate the device under test.

[0111] The socket body 110 is fixed to the test equipment. The device under test is housed in the socket body 110. Therefore, during the test, the device under test can be stably electrically connected to the test equipment.

[0112] In the socket body 110, mounting portions 112 are disposed around the receiving portion 111 for mounting the fixing device 120. A pair of mounting portions 112 may be formed on both sides of the receiving portion 111, with the receiving portion 111 located therebetween. The mounting portion 112 includes a rectangular mounting hole 1121 and fitting portions 1122 disposed on both sides of the mounting hole 1121 and recessed from the upper surface of the socket body 110.

[0113] Mounting hole 1121 has a shape corresponding to operating portion 132 of housing 130. Mounting hole 121 has a rectangular cross-sectional shape. Operating portion 132 of housing 130 is inserted into mounting hole 1121.

[0114] The fixing portion 131 of the housing 130 is placed on and fixed to the fitting portion 1122. The fitting portion 1122 has a shape corresponding to the fixing portion 131. With the fixing portion 131 placed on the fitting portion 1122, the fixing portion 131 is fixed to the fitting portion 1122 using bolts 131a.

[0115] The fixing device 120 is installed around the receiving portion 111 of the socket body 110 and is detachably fixed to the object 170 inserted into the receiving portion 111.

[0116] The fixing device 120 includes a housing 130, a locking device 140, a pushing member 150, and a first spring 160.

[0117] The housing 130 is fixed to the socket body 110. The locking device 140 is slidable within the housing 130. The housing 130 includes a fixed portion 131 and an operating portion 132.

[0118] The fixing portion 131 protrudes from the left and right sides of the operating portion 132. Bolt holes are formed in the fixing portion 131 to receive bolts 131a. The bolt holes extend in the vertical direction VD. With the fixing portion 131 placed on the fitting portion 1122 of the socket body 110, the fixing portion 131 is fixed to the socket body 110 using bolts 131a.

[0119] The operating portion 132 has a hexahedral shape, an opening at the bottom, and is hollow inside. A locking device 140 is inserted into the lower side of the opening in the operating portion 132. The locking device 140 slides horizontally within the operating portion 132. The operating portion 132 is cut on one side in the second horizontal direction HD2, and the locking portion 142 of the locking device 140 protrudes from the cut portion.

[0120] An insertion hole 1321 is formed on the upper surface of the operating portion 132. The insertion hole 1321 is formed by penetrating the operating portion 132 in the vertical direction VD. The insertion hole 1321 guides the push member 150 to move in the vertical direction VD. When the operator presses the push member 150 inserted into the insertion hole 1321, the push member 150 descends; when the push member 150 rises, it is re-inserted into the insertion hole 1321.

[0121] Guide members 1322 are disposed in the operating portion 132 to guide the movement of the pushing member 150 in the vertical direction VD. Guide members 1322 extend into the operating portion 132 in the second horizontal direction HD2 and the vertical direction VD. The body 151 of the pushing member 150 is located between the guide members 1322. The body 151 of the pushing member 150 is fitted between the guide members 1322 and is movable along the guide members 1322 in the vertical direction VD.

[0122] The locking device 140 slides horizontally within the housing 130. The locking device 140 is movable between an open position where the locking device 140 opens the receiving portion 111 and a locked position where at least a portion of the locking device 140 is inserted into the receiving portion 111. When the locking device 140 is moved to the locked position, the locking device 140 prevents the object 170 inserted into the receiving portion 111 from being released from the receiving portion 111.

[0123] The locking device 140 includes a slider 141, a locking portion 142, and a bushing 143.

[0124] The slider 141 is inserted into the operating portion 132 of the housing 130 and can slide in the second horizontal direction HD2. The slider 141 includes a front wall 1411 extending in the first horizontal direction HD1, a pair of side walls 1412 extending in the second horizontal direction HD2 from both sides of the front wall 1411, and a support rod 1413 disposed inside the side walls 1412 and extending from the front wall 1411 in the second horizontal direction HD2.

[0125] Sidewalls 1412 are formed at both ends of the front wall 1411, and support rods 1413 are formed in the center portion of the front wall 1411. The sidewalls 1412 extend from both sides of the front wall 1411 away from the receiving portion 111 along the second horizontal direction HD2, and the support rods 1413 extend from the center portion of the front wall 1411 away from the receiving portion 111 along the second horizontal direction HD2.

[0126] The sidewall 1412 extends from both sides of the front wall 1411 along the second horizontal direction HD2.

[0127] A guide hole 1412a extending along the second horizontal direction HD2 is formed in the sidewall 1412 to receive the guide rod 161. The guide hole 1412a has an inner diameter corresponding to the diameter of the guide rod 161, and a stepped portion 1412b is formed at the end of the guide hole 1412a, so that the head portion 1611 of the guide rod 161 can be engaged with the stepped portion 1412b. The stepped portion 1412b, together with the guide rod 161, engages and supports the first spring 160.

[0128] A pin hole 1412c extending along the first horizontal direction HD1 is formed in the sidewall 1412 to receive a support pin 1431. The support pin 1431 is positioned on the first horizontal direction HD1 through the pin hole 1412c.

[0129] Support rods 1413 extend from the front wall 1411 along the second horizontal direction HD2 and form a pair that are spaced apart from each other. Support rods 1413 are disposed between side walls 1412, and bushings 143 are disposed between support rods 1413.

[0130] The locking portion 142 protrudes from the slider 141 along the second horizontal direction HD2. The locking portion 142 extends toward the object 170 housed in the receiving portion 111.

[0131] When the slider 141 moves to the open position, the locking part 142 disengages from the receiving part 111, allowing the object 170 to enter or exit the receiving part 111.

[0132] When slider 141 moves to the locked position, object 170 contained in receiving portion 111 is prevented from rising or escaping because locking portion 142 holds object 170 in place, thus preventing object 170 from being released from receiving portion 111. When slider 141 is in the locked position, locking portion 142 is positioned in the vertical movement path of object 170, preventing object 170 from being released.

[0133] Bushing 143 is disposed between support rods 1413 and is rotatably supported by support pin 1431. Bushing 143 is the component that contacts the inclined surface 1521 of push member 150. When push member 150 is lowered, bushing 143 is pushed, and correspondingly, slider 141 moves in the second horizontal direction HD2. Bushing 143 slides in contact with inclined surface 1521, thus a smooth contact can be achieved between bushing 143 and inclined surface 1521.

[0134] A pushing member 150 is disposed within the housing 130 and is movable within the housing 130 in the vertical direction VD. The pushing member 150 can move the locking device 140 to one of an open position and a locked position by contacting the locking device 140. The pushing member 150 includes a body 151 and a contact portion 152.

[0135] The body 151 has an approximately quadrilateral shape and is configured to be inserted into an insertion hole 1321 of the housing 130 and pressed by the operator. The upper surface of the body 151 is inserted into the insertion hole 1321 and configured to move in a vertical direction VD within an operating portion 132 of the housing 130. The body 151 is movable in the vertical direction VD while being guided by a guide 1322 of the operating portion 132. A plurality of protrusions protrude downward from two lower sides of the body 151. These protrusions form a pair and contact the guide 1322.

[0136] The contact portion 152 protrudes downward from the center of the body 151, and a ramp 1521 is formed on one side of the contact portion 152. The ramp 1521 slopes downward toward the object 170 housed in the receiving portion 111. When the pushing member 150 is lowered, the bushing 143 moves horizontally along the ramp 1521 in a direction away from the object 170, and correspondingly, the locking portion 142 of the locking device 140 moves out of the receiving portion 111.

[0137] The first spring 160 is disposed between the locking device 140 and the head portion 1611 of the guide rod 161. When the pushing member 150 is lowered, the locking device 140 moves along the inclined surface 1521 of the pushing member 150, and the first spring 160 elastically biases the locking device 140 in a direction opposite to the direction of movement of the locking device 140.

[0138] A head portion 1611 is formed at one end of the guide rod 161, and the other end of the guide rod 161 is threaded. The threaded other end of the guide rod 161 is fixed to the housing 130. With the housing 130 connected to the locking device 140, the guide rod 161 is inserted into the guide hole 1412a, and then the other end of the guide rod 161 is screwed into the housing 130.

[0139] A first spring 160 is fitted around the guide rod 161. One end of the first spring 160 is supported by the head portion 1611, and the other end is supported by the inner surface of the stepped portion 1412b in the guide hole 1412a. The first spring 160 elastically biases the locking device 140 toward the locked position. When the operator presses the push member 150 in this state, the push member 150 lowers, and the locking device 140 moves to the open position. Subsequently, when the pressing force applied to the push member 150 is removed, the locking device 140 moves to the locked position due to the restoring elastic force of the first spring 160. At the same time, the push member 150 is raised from the downward moving state by the locking device 140.

[0140] Figures 5 to 8 The operating state of the test socket 100 according to the first embodiment is described.

[0141] first, Figure 5 and Figure 6 The state of the test socket 100 is described before the pushing member 150 is lowered. When the pushing member 150 is raised, the locking part 142 of the locking device 140 is inserted into the receiving part 111 to prevent the object 170 from separating.

[0142] Specifically, the bushing 143 contacts the lower end of the inclined surface 1521, and the locking portion 142 is inserted into the receiving portion 111 and located on the upper part of the object 170, which is the test device. Furthermore, when the pushing member 150 is fully raised, the upper surface of the pushing member 150 is located within the insertion hole 1321.

[0143] After that, as Figure 7 and Figure 8As shown, when the operator presses the push member 150, the push member 150 lowers, and the inclined plane 1521 also lowers. At this time, the bushing 143 moves horizontally along the inclined plane 1521. As the bushing 143 moves, the locking device 140 also moves horizontally. Because the guide rod 161 is inserted into the locking device 140, the movement path of the locking device 140 is restricted to the horizontal direction HD, and as the push member 150 lowers, the locking device 140 moves horizontally away from the object 170.

[0144] When the pushing member 150 is fully lowered, the locking portion 142 is released from the receiving portion 111, so that the object 170 can be separated from the socket body 110. After the tested device object 170 has been fully tested, the operator can separate and remove the tested device from the test socket 100.

[0145] The test socket 100 of this utility model is not limited to this, and can be modified as follows.

[0146] Figures 9 to 14 The test socket 200 according to the second embodiment is described. The test socket 200 of the second embodiment is configured such that when the pushing member 250 is lowered, the locking portion 242 of the locking device 240 can move to the locked position to prevent the object 170 from being separated.

[0147] According to the second embodiment, the fixing device 220 of the test socket 200 includes a housing 230, a locking device 240, and a pushing member 250. The housing 230 is fixed to the socket body 210. The locking device 240 is mounted in the housing 230 and can slide horizontally within the housing 230. The locking device 240 moves between an open position where the locking device 240 opens the receiving portion and a locked position where the locking device 240 is inserted into the receiving portion. When the locking device 240 moves to the locked position, the locking device 240 prevents the object 170 inserted into the receiving portion from separating from the receiving portion. The pushing member 250 is disposed in the housing 230 and can move vertically within the housing 230. The pushing member 250 contacts the locking device 240, causing the locking device 240 to move to one of the open position and the locked position.

[0148] The inclined surface 2521 provided on the contact portion 252 of the push member 250 slopes downward in a direction away from the object 170. When the push member 250 is lowered, the bushing 243 moves horizontally toward the object 170 along the inclined surface 2521, and correspondingly, the locking portion 242 of the locking device 240 is inserted into the receiving portion.

[0149] Figure 13 and Figure 14 The operating state of the test socket 200 in the second embodiment is described.

[0150] like Figure 13As shown, when the operator presses the pushing member 250, the pushing member 250 lowers, and simultaneously, the inclined plane 2521 lowers. At this time, the bushing 243 moves horizontally along the inclined plane 2521. Because the guide rod 261 is inserted into the locking device 240, the movement path of the locking device 240 is restricted to the horizontal direction HD parallel to the length direction of the guide rod 261.

[0151] As the pushing member 250 lowers, the locking device 240 moves horizontally toward the object 170. When the pushing member 250 is fully lowered, the locking portion 242 prevents the object 170 inserted into the receiving portion from being separated. Specifically, in the lowered state of the pushing member 250, the locking portion 242 of the locking device 240 is inserted into the receiving portion to prevent the object 170 from being separated. As the pushing member 250 descends and the locking device 240 slides, the first spring 260 is gradually compressed.

[0152] Subsequently, when the operator removes the pressing force from the pushing component 250, such as Figure 14 As shown, compressing the first spring 260 causes the locking device 240 to move away from the object 170 while returning to its original shape. Specifically, when the locking portion 242 disengages from the object 170, the object 170 within the receiving portion becomes detachable from the socket body 210. Subsequently, the bushing 243 raises the ramp 2521. Accordingly, the pushing member 250 is raised into the insertion hole of the housing 230.

[0153] At this point, the bushing 243 contacts the lower part of the inclined surface 2521, and the locking part 242 is released from the receiving part.

[0154] Figures 15 to 17 This describes the test socket 300 according to the third embodiment of the present invention.

[0155] According to the third embodiment of the present invention, the test socket 300 includes a socket body 310 and a fixing device 320.

[0156] The socket body 310 has a square plate shape, and a square receiving portion 311 is disposed in the center of the socket body 310. The receiving portion 311 is a through hole formed in the vertical direction VD, and has a shape corresponding to the outline of the object 170 to accommodate the object 170. The socket body 310 is fixed to the test equipment so that the object 170 accommodated in the socket body 310 can be stably electrically connected to the test equipment during the test.

[0157] The socket body 310 includes a mounting portion 312 around the receiving portion 311 for mounting the fixing device 320 in the mounting portion 312.

[0158] The mounting portion 312 includes a rectangular mounting hole 3121, a pair of docking portions 3122 provided on both sides of the mounting hole 3121, and a fitting portion 3123 provided on one side of the mounting hole 3121 relative to the receiving portion 311.

[0159] The mounting hole 3121 has an approximately square cross-sectional shape. The lower surface of the locking device 340 slides in contact with the peripheral area of ​​the mounting hole 3121.

[0160] A docking portion 3122 is formed on both sides of the mounting hole 3121, and a pushing member 350 and a guide portion 360 are disposed on the docking portion 3122. Specifically, the guide portion 360 and the edges of the pushing member 351 are disposed on a pair of docking portions 3122. The guide portion 360 is fixed to the docking portion 3122 to support the pushing member 351 and prevent the pushing member 351 from detaching from the socket body 310.

[0161] The fitting portion 3123 is disposed on the edge of the mounting hole 3121 in the second horizontal direction HD2. A support wall 3123a is formed upright on the fitting portion 3123, and a spring bracket 3123b is connected to the fitting portion 3123. The second spring 370, which contacts the support wall 3123a, is prevented from disengaging by the spring bracket 3123b. With the spring bracket 3123b fixed to a flat portion extending horizontally from the upper end of the support wall 3123a, the spring bracket 3123b bends downwards. A spring support hole 3123c is formed in the portion of the spring bracket 3123b facing the support wall 3123a. The second spring 370 is inserted into the spring support hole 3123c, thereby preventing it from disengaging from the socket body 310.

[0162] The fixing device 320 includes a locking device 340, a pushing member 350, a guide portion 360, and a second spring 370.

[0163] The locking device 340 is installed in the socket body 310 and can slide in the second horizontal direction HD2. The locking device 340 can move between an open position and a locked position. In the open position, the locking device 340 opens the receiving portion 311, and in the locked position, the locking device 340 is inserted into the receiving portion 311. When the locking device 340 moves to the locked position, the locking device 340 prevents the object 170 inserted into the receiving portion 311 from dislodging.

[0164] The locking device 340 includes a slider 341 and a locking portion 342. The lower surface of the slider 341 is in movable contact with the socket body 310. The locking portion 342 protrudes from the end of the slider 341 and, when the locking device 340 is in the locked position, the locking portion 342 protrudes into the receiving portion 311 to prevent the device under test from being released.

[0165] The slider 341 can slide horizontally while its lower surface is in contact with the upper surface of the socket body 310. The slider 341 includes an inclined surface 3411 that contacts the push member 350. The inclined surface 3411 is inclined downward toward the object 170. Therefore, when the push member 350 is lowered, the inclined surface 3411 of the locking device 340 moves horizontally.

[0166] The pushing member 350 is movable in the vertical direction VD and can move the locking device 340 to one of the open or locked positions by contacting it. The pushing member 350 includes a pushing body 351 and a bushing 352.

[0167] The pusher 351 has an approximately rectangular shape. Because the edge of the pusher 351 interferes with the head portion of the guide portion 360, it prevents the pusher 351 from disengaging. The edge of the pusher 351 can move up and down within a predetermined distance in the vertical direction VD between the head portion of the guide portion 360 and the bottom surface of the resting portion 3122. Even if the pusher 351 rises, it will not disengage because its edge is held in place by the head portion of the guide portion 360. The pusher 351 is elastically biased upwards by a third spring 3512 provided on the resting portion 3122.

[0168] Multiple support members 3511 protrude downward from the lower surface of the pusher body 351. The support members 3511 are separated from each other in the first horizontal direction HD1, and bushings 352 are disposed between the support members 3511.

[0169] The bushing 352 slides in contact with the inclined surface 3411 of the locking device 340 and is rotatably supported by the support member 3511 via the support pin 3521. When the pushing member 350 is lowered, the bushing 352 slides along the inclined surface 3411.

[0170] The guide portion 360 is fixed to the socket body 310 and guides the movement of the pushing member 350. The guide portion 360 is a pair of vertical pins fixed to the socket body 310 in the vertical direction VD. The pushing member 350 is mounted between the pair of vertical pins, and the movement of the pushing member 350 is guided by the pair of vertical pins.

[0171] The head portion is located at the upper end of the guide portion 360, and the lower end of the guide portion 360 is threaded for screwing into the docking portion 3122. The head portion of the guide portion 360 prevents the pushing member 350 from disengaging.

[0172] The second spring 370 is arranged between the slider 341 and the support wall 3123a. When the slider 341 of the locking device 340 moves, the second spring 370 elastically biases the locking device 340 in the opposite direction to its movement. Specifically, one end of the second spring 370 contacts the support wall 3123a, and the other end of the second spring 370 contacts the slider 341, elastically biasing the slider 341 in a direction away from the support wall 3123a. Here, the spring bracket 3123b prevents the second spring 370 from disengaging.

[0173] Figure 18 and Figure 19 The operating state of the test socket 300 according to the third embodiment is described.

[0174] first, Figure 18 This describes the state of the test socket 300 before the push member 350 is made. When the push member 350 is raised, the locking part 342 of the push member 350 is inserted into the receiving part 311 to prevent the object 170 from falling out.

[0175] Specifically, the bushing 352 contacts the upper portion of the inclined surface 3411, and the locking portion 342 is inserted into the receiving portion 311. At this time, the pushing member 350 is in the raised state. In addition, the edge of the pushing body 351 is supported by the head portion of the guide portion 360, so the pushing body 351 will not detach from the socket body 310.

[0176] Subsequently, when the operator... Figure 19 When the push member 350 is pressed down, it lowers, and simultaneously, the bushing 352 lowers in the vertical direction VD. At this time, as the inclined surface 3411 is pressed down by the bushing 352, the locking device 340 moves horizontally. The locking device 340 moves horizontally with its lower surface in contact with the bottom surface around the mounting hole 1121.

[0177] When the pushing member 350 is fully lowered, the locking portion 342 releases from the receiving portion 311, allowing the object 170 to be removed from the test socket 300. After the tested object 170 has been fully inspected, the operator can separate the object 170 from the test socket 300 by pressing the pushing member 350.

[0178] Although embodiments of the present invention have been described with reference to the accompanying drawings, these embodiments are merely examples, and those skilled in the art will readily recognize that various modifications and variations can be made therein. Therefore, the scope of the present invention should be defined by the appended claims.
