[0035] In order to be able to more clearly understand the above objects, technical solutions and advantages of this application, the following will combine the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application, and have a detailed understanding of how to solve the problems proposed in the above background technology.

[0036] As Figures 1 to 8 shown, a downward pressure test seat for chip testing includes an upper base 1 and a lower base 2 that are injection-molded in cooperation with each other. An elastic member 3 and two sets of downward pressure components 4 that cooperate with the elastic member 3 are connected between the upper base 1 and the lower base 2. A fixing member 5 is detachably installed on the lower base 2.

[0037] Specifically, including but not limited to, in this embodiment, the upper base 1 and the lower base 2 can be plastic parts formed by injection molding. Of course, the downward pressure components 4 and the fixing member 5 can also be set as plastic parts according to actual needs, and are quickly formed by an injection molding machine, effectively reducing production costs; the upper base 1 and the lower base 2 are matched to form a square structure. The elastic member 3 and the downward pressure components 4 are both used to fixedly connect the upper base 1 and the lower base 2, and the two cooperate with each other to enable the upper base 1 to move down or up relative to the lower base 2. The fixing seat can carry the chip. The two sets of downward pressure components 4 are symmetric with each other and are respectively arranged on both sides of the upper base 1 and the lower base 2. Based on this, when the upper base 1 is pressed down, the downward pressure components 4 release the chip, and at this time, the chip can be taken out or put in. When the upper base 1 rises, the downward pressure components 4 press the chip tightly, and at this time, the chip can be quickly tested.

[0038] Through the above solution, the structure of the test seat is simple, and the plastic parts formed by injection molding can reduce the later processing and manufacturing, and reduce the production and maintenance costs.

[0039] As a specific improvement embodiment, as Figure 1 and Figure 6 shown, the downward pressure component 4 includes a first fixing rod 41 and a second fixing rod 42 that are parallel to each other. The first fixing rod 41 is fixedly connected to the upper base 1, and the second fixing rod 42 is fixedly connected to the lower base 2.

[0040] Specifically, including but not limited to, there are two first fixing rods 41 and two second fixing rods 42, both of which are cylindrical rods. The first fixing rods 41 and the second fixing rods 42 are parallel to each other and horizontally arranged. In this embodiment, the upper base 1 extends downward corresponding to the pressing component 4, and the extended part has a notch. The pressing component 4 is placed at the notch, and the extended part is provided with a through hole for installing the first fixing member 5. The through hole is communicated with the notch. Thus, the first fixing rod 41 can pass through from the two side through holes, so as to realize the fixed connection between the first fixing rod 41 and the upper base 1; the lower base 2 is recessed inward corresponding to the extended part of the upper base 1 to provide space for the upper base 1 to rise or fall. The recess also has a notch, and through holes horizontally penetrating the entire lower base 2 are provided on both sides of the notch. The second fixing rod 42 can be inserted from both sides, so as to realize the fixed connection between the second fixing rod 42 and the lower base 2. When disassembling the first fixing rod 41 and the second fixing rod 42, just pull them out from the through holes.

[0041] Through the above solution, the first fixing rod 41 and the second fixing rod 42 are respectively detachably connected to the upper base 1 and the lower base 2, and the quick disassembly and assembly of the test seat can be realized.

[0042] As a specific improvement embodiment, as Figure 1 、 Figures 6 to 8 shown, the pressing component 4 further includes a pressing block 43 and a traction piece 44 connected to the pressing block 43. The pressing block 43 is fixedly connected to the first fixing rod 41, and the traction piece 44 is fixedly connected to the second fixing rod 42.

[0043] Specifically, including but not limited to, both the pressing block 43 and the traction piece 44 are arc-shaped structures. A through hole is opened at one end of the pressing block 43, and this through hole corresponds to the through hole of the upper base 1. Then one end of the pressing block 43 can be embedded in the notch of the upper base 1. Thus, when the first fixing rod 41 is inserted from the through holes on both sides of the notch of the upper base 1, it passes through the through hole of the pressing block 43, so as to realize the fixed connection among the pressing block 43, the first fixing rod 41 and the upper base 1; when the second fixing rod 42 is inserted from the through hole of the lower base 2, it passes through one end of the traction piece 44, so as to realize the fixed connection between the traction piece 44 and the second fixing rod 42.

[0044] Through the above solution, the pressing block 43 is detachably connected to the first fixing rod 41, and the traction piece 44 is detachably connected to the second fixing rod 42, and the quick disassembly and assembly of the test seat can be further realized.

[0045] As a specific improvement embodiment, as Figure 6 and Figure 7As shown in the figure, the pressing block 43 is provided with at least two first connection holes 431 and a through groove 432. The first connection holes 431 communicate with the through groove 432. One end of the traction piece 44 is provided with a second connection hole 441. The traction piece 44 is embedded in the through groove 432 so that the first connection hole 431 corresponds to the second connection hole 441.

[0046] Specifically, including but not limited to, both the first connection hole 431 and the second connection hole 441 are cylindrical holes, and the first fixing hole penetrates through the entire pressing block 43. In this embodiment, two first connection holes 431 are provided and arranged along the side surface of the pressing block 43. The through groove 432 also penetrates through the entire pressing block 43 to communicate the top surface and the bottom surface. At the same time, the first connection hole 431 communicates with the through groove 432. One end of the traction piece 44 close to the first fixing rod 41 is provided with a second connection hole 441. The end of the traction piece 44 far from the first fixing rod 41 is embedded in the through groove 432. The width of the through groove 432 is greater than the width of the traction piece 44, which can avoid frictional blockage when the traction piece 44 rotates. Then when the traction piece 44 is installed, the first connection hole 431 and the second connection hole 441 can be kept in a straight line.

[0047] Through the above solution, the mutual cooperation of multiple first connection holes 431 and the traction piece 44 can be adapted to chips of different thicknesses for adjustment, realizing the control of the pressing height of the pressing block 43, and improving the adaptability and practicability of the test socket.

[0048] As a specific embodiment of the improvement, as Figures 6 to 8 shown, the pressing-down assembly 4 further includes a fixing pin 45, and the fixing pin 45 is inserted into the first connection hole 431 and the second connection hole 441.

[0049] Specifically, including but not limited to, the fixing pin 45 is a countersunk columnar structure with a pointed end at one end and a head at the other end. The diameter of the head is slightly larger than the diameter of the pointed end. Based on this, when the pressing block 43 and the traction piece 44 need to be installed, the fixing pin 45 is inserted into the first connection hole 431 and passes through the second connection hole 441. At this time, the first connection hole 431 can be selected according to actual needs. On the contrary, when the pressing block 43 and the traction piece 44 need to be disassembled, only the fixing pin 45 needs to be pulled out.

[0050] Through the above solution, the fixing pin 45 can realize the quick disassembly and assembly of the pressing block 43 and the traction piece 44, further improving the disassembly and assembly efficiency of the test socket and ensuring the structural stability.

[0051] As a specific embodiment of the improvement, as Figures 6 to 8 shown, the other end of the traction piece 44 is provided with a third connection hole 442, and the second fixing rod 42 is inserted into the third connection hole 442. Correspondingly, a groove 22 is provided on the lower base 2 below the second fixing rod 42, and the traction piece 44 is embedded in the groove 22.

[0052] Specifically, including but not limited to, the second connection hole 441 and the third connection hole 442 are respectively arranged at both ends of the traction piece 44. The second connection hole 441 is used for the rotational connection with the pressing block 43, and the second fixing rod 42 is inserted into the third connection hole 442 for the fixed connection between the traction piece 44 and the second fixing rod 42, so that the upper base 1, the first fixing rod 41, the pressing block 43 and the traction piece 44 can be linked to realize the downward pressure or contraction of the pressing block 43. At this time, the groove 22 is opened at the notch of the lower base 2 and below the second fixing rod 42. When the traction piece 44 is installed on the second fixing rod 42, part of it is embedded in the groove 22, which can prevent the traction piece 44 from sliding left and right and causing deviation.

[0053] Through the above solution, the traction piece 44 can rotate relative to the second fixing rod 42 and the fixing pin 45, and being embedded in the groove 22 can prevent the pressing block 43 from deviating, ensuring the service life of the test socket and the precise fixation of the chip.

[0054] As a specific implementation of the improvement, as Figure 1 、 Figure 3 and Figure 4 shown, mounting grooves 11 are opened at the bottoms of the four corners of the upper base 1. One end of the elastic member 3 is fixedly installed in the mounting grooves 11. Correspondingly, mounting holes 21 are opened at the four corners of the lower base 2, and the mounting grooves 11 correspond to the mounting holes 21 so that the other end of the elastic member 3 can be inserted into the mounting holes 21 for fixation.

[0055] Specifically, including but not limited to, the structures of the mounting grooves 11 and the mounting holes 21 are one of circular and polygonal. There are 4 mounting grooves 11. One end of the elastic member 3 extends into the mounting grooves 11 and is fixedly connected to the upper base 1. There are 4 corresponding elastic members 3, and the elastic members 3 and the upper base 1 are integrally formed. Correspondingly, there are 4 mounting holes 21 and they penetrate the entire lower base 2. The mounting holes 21 can be countersunk holes from the top surface to the bottom surface. The mounting grooves 11 and the mounting holes 21 correspond up and down. Based on this, when the upper base 1 and the lower base 2 are installed, the other end of the elastic member 3 can be extended into the mounting holes 21 for fixation. On the contrary, when disassembly is required, the elastic member 3 can be taken out.

[0056] Through the above solution, the rapid disassembly and assembly of the upper base 1, the elastic member 3 and the lower base 2 can be realized, further improving the disassembly and assembly efficiency of the test socket, and using the elastic force of the elastic member 3 to reset the upper base 1.

[0057] As a specific implementation of the improvement, as Figure 1 and Figure 5 shown, a fixing ring 31 is fixedly arranged at one end of the elastic member 3, and the fixing ring 31 is embedded in the mounting hole 21 so that the fixing ring 31 is fixedly connected to the lower base 2, and the elastic member 3 is a compression spring.

[0058] Specifically, including but not limited to, in this embodiment, the fixing ring 31 can be a nut. The fixing ring 31 and the elastic member 3 are integrally formed. The diameter of the lower part of the mounting hole 21, the outer diameter of the fixing ring 31, and the diameter of the upper part of the mounting hole 21 increase in sequence. Then, when the elastic member 3 is inserted into the mounting hole, a screw can be inserted from the bottom of the mounting hole 21 and tightened with the fixing ring 31. The reverse operation can be performed during disassembly.

[0059] Through the above solution, the disassembly and assembly of the lower base 2 and the elastic member 3 can be realized, ensuring the structural stability.

[0060] As a specific improvement embodiment, as Figure 1 and Figure 4 shown, the fixing member 5 includes a limiting frame 51 and a positioning plate 52 that are engaged and clamped with each other. The limiting frame 51 is clamped with the lower base 2, and the positioning plate 52 is matched with the pressing component 4 to press or release the chip.

[0061] Specifically, including but not limited to, the lower base 2 is a frame structure. At this time, the bottom of the lower base 2 is provided with clamping posts and clamping grooves. The limiting frame 51 and the positioning plate 52 are clamped with each other, and the positioning plate 52 is located at the center of the limiting frame 51. At this time, the chip can be placed in the clamping groove provided on the positioning plate 52, which can prevent the chip from shifting. Two support plates are also provided at the bottom of the positioning plate 52. The support plates can be fixedly connected to the lower base 2 to fix the positioning plate 52. The positioning plate 52 and the support plates are provided with probe holes that communicate with each other up and down and correspond to each other, facilitating the testing of the chip.

[0062] Through the above solution, the quick disassembly and assembly of the fixing member 5 can be realized, further improving the disassembly and assembly efficiency of the test socket and ensuring the accuracy of the chip positioning and placement.

[0063] Finally, it should be noted that the above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
