[0016] The present invention will be further described below in conjunction with embodiments.

[0017] Embodiment: A high-efficiency mechanism integrating the withstand voltage test and pin pressing of a circulator and an isolator, as Figure 1 shown, includes a frame 1, a lower test seat 3, an upper test seat 4, and a telescopic electrode 5, wherein: The frame 1, as Figure 2 shown, includes a guide rail 1-1, a conveyor plate 1-2, an upper test seat mounting plate 1-3, a buffer 1-4, a cylinder 1-5, a guide pillar 1-6, a guide sleeve 1-7, and a servo motor 1-8; Among them, the lower end of the guide rail 1-1 is fixed on the frame base, and the upper sliding part is installed below the conveying plate 1-2 to ensure smooth front and back sliding of the conveying plate 1-2; threaded holes are provided above the conveying plate 1-2 for installing the lower test seat pressing strip A 3-7 and the lower test seat pressing strip B 3-16; the upper test seat mounting plate 1-3 is fixed on the guide sleeve 1-7, and the guide sleeve 1-7 is sleeved on the guide post 1-6 to make the upper test seat mounting plate 1-3 move up and down in parallel; the cylinder 1-5 is connected to the upper end of the upper test seat mounting plate 1-3 to drive the upper test seat mounting plate 1-3 to move together. A screw through hole A 1-3-1 is provided on the upper test seat mounting plate 1-3, which cooperates with the threaded hole A 4-3-1 of the fixed column 4-3- to fix the upper test seat 4 on the frame 1; the buffer 1-4 is fixed on the frame to buffer when the upper test seat mounting plate 1-3 reaches the upper limit; the servo motor 1-8 is fixed on the frame, the output shaft is connected to the synchronous pulley + belt, and the belt is connected to the lower part of the conveying plate 1-2. When the motor rotates, the belt drives the conveying plate 1-2 to move precisely back and forth. The conveying plate 1-2 of the entire frame 1 moves precisely and smoothly back and forth, and the upper test seat mounting plate 1-3 moves smoothly up and down.

[0018] The assembled front of the said lower test seat 3 is as Figure 3 shown, and the back is as Figure 4 shown; the exploded view is as Figure 6 shown, including: nut A 3-1, stud 3-2, lower test seat base plate 3-3, spring A 3-4, positioning pin A 3-5, lower ejector pin 3-6, pressing plate A 3-7, lower insulating plate 3-8, lower test seat positioning sleeve 3-9, lower test plate 3-10, insulating screw combination A 3-11, insulating screw combination B 3-12, product positioning plate 3-13, screw A 3-14, positioning pin B 3-15 and pressing plate B 3-16; Among them, the lower test seat base plate 3-3, as Figure 8 (front), Figure 9 (back) shown, includes: spring hole B 3-3-1, positioning pin hole A 3-3-2, threaded hole B 3-3-3, threaded hole C 3-3-4, upper plane 3-3-5, positioning pin hole B 3-3-6, stepped hole 3-3-7, waist-shaped stepped hole 3-3-8, boss 3-3-9, notch surface 3-3-10, threaded hole D 3-3-11; Among them, the insulating screw combination B 3-12, as Figure 7 shown, includes: insulating ring 3-12-1, flat gasket 3-12-2, screw B 3-12-3; The lower ejector pin 3-6, as Figure 10 shown, includes: large end face 3-6-1, cylindrical surface 3-6-2, small end face 3-6-3. The insulating screw combination A 3-11 and the insulating screw combination B 3-12 have the same structure and function, only the specification sizes are different.

[0019] The pressing plate A 3-7, as Figure 5 shown, includes: the screw through-hole B3-7-1, the spring hole A 3-7-2.

[0020] The lower test plate 3-10, as Figure 11 (front), Figure 12 (back) shown, includes: the positioning pin hole C 3-10-1, the warping opening 3-10-2, the insulating screw through-hole B 3-10-3, the insulating screw through-hole C 3-10-4, the positioning pin hole D 3-10-5, the ejector pin hole 3-10-6, the threaded hole 3-10-7, the permanent magnet embedded hole 3-10-8, the positioning sleeve hole 3-10-9.

[0021] Nut A3-1 is screwed with stud 3-2 and then screwed into threaded hole C 3-3-4. By tightening nut A3-1, the position of the extended part of stud 3-2 can be fixed. The lower test seat base plate 3-3, made of steel, serves as the base body for fixing other components. Spring A 3-4 has one end inserted into spring hole A 3-7-2 corresponding to pressing plate A 3-7 and the other end inserted into spring hole B 3-3-1. When pressing plate A3-7 is fixed in the threaded hole corresponding to conveyor plate 1-2 by a screw passing through screw through hole B3-7-1, spring A3-4 presses the lower test seat base plate 3-3 against the surface of conveyor plate 1-2 to form a constant-force and flexible connection. Positioning pin A 3-5, made of insulating material, with a total of 2 pieces, has one end inserted into positioning pin hole A 3-3-2, passing through the corresponding hole of lower insulating plate 3-8 and inserted into positioning pin hole C 3-10-1 to relatively fix the positions of lower test seat base plate 3-3, lower insulating plate 3-8, and lower test plate 3-10. Lower ejector pin 3-6 is made of ceramic material, having the characteristics of insulation and hardness. The large end face 3-6-1 abuts against the upper plane 3-3-5 of lower test seat base plate 3-3, and the cylindrical surface 3-6-2 passes through the corresponding round hole of lower insulating plate 3-8 and is inserted into ejector pin hole 3-10-6. Ejector pin hole 3-10-6 is a through hole, and the small end face 3-6-3 can be seen on the upper surface of lower test seat 3 after assembly. Pressing plate A 3-7 and pressing plate B 3-16 have a mirror-symmetrical structure, with 2 screw through holes B 3-7-1 on the front and 2 spring holes A 3-7-1 on the back. Lower insulating plate 3-8 is made of insulating material and is the electrical isolation wall inside the entire lower test seat 3, separating the components above and below lower insulating plate 3-8. The small ends of two lower test seat locating sleeves 3-9 are inserted into locating sleeve holes 3-10-9, and the inner holes are through holes, which are matched with the outer diameter of alignment pin 4-7. When lower test seat 3 and upper test seat 4 are installed on frame 1, the upper and lower test seats approach and align, and upper test seat 4 is positioned. At this time, the axial positions of threaded hole A 4-3-1 and screw through hole A 1-3-1 are positioned. By screwing to fasten upper test seat mounting plate 1-3 and lower test seat 3, it can be ensured that lower test seat 3 and upper test seat 4 can be perfectly aligned at a certain position in terms of hardware, and during use, if the position shifts and alignment pin 4-7 cannot be inserted into the corresponding inner hole of lower test seat locating sleeve 3-9, it can prevent the hardware from being damaged.

[0022] Among them, the lower test board 3-10 is made of metal. When the product positioning board 3-13 fits with the test board 3-10, due to the positioning of the positioning pin B 3-15, the two fit tightly, and the lifting notch 3-10-2 facilitates separating the two with tools; the insulating screw assembly A 3-11 and the insulating screw assembly B 3-12 respectively pass through the insulating screw through hole B 3-10-3 and the insulating screw through hole A 3-10-4, and are screwed into 3-3-3 and 3-3-11; tightening the screws in 3-11 and 3-12 can combine and press 3-10, 3-8, and 3-3 together. One end of the positioning pin B 3-15 is inserted into the positioning pin hole D 3-10-5, and the other end is inserted into the corresponding pin hole of the product positioning board 3-13 to accurately position the lower test board 3-10 and the product positioning board 3-13. The screw A 3-14 passes through the product positioning board 3-13 and is screwed into the threaded hole 3-10-7 to press the two together. The permanent magnet embedded hole 3-10-8 is a stepped hole, and a permanent magnet can be embedded inside according to needs. The permanent magnet will provide a certain suction force to adsorb the product 2, but the force is much smaller than the force required to take out the product 2, preventing the product 2 from jumping out of the corresponding pit of the product positioning board 3-13 during the operation process.

[0023] For the lower test seat 3, the small end face 3-6-3 after assembly has a continuously adjustable height, which can be higher or lower than the upper plane 3-3-5, depending on the specific requirements of the product 2 to be leveled. This invention can operate on 6 products 2 at a time, but is not limited to 6 products 2. Each product of this type of test seat 3 can independently adjust the leveling size and can be conveniently adjusted during use. Since both the lower test board 3-10 and the product positioning board 3-13 are made of metal and can conduct electricity, they are an electrode during voltage withstand testing. However, the lower insulating board 3-8 is an insulating wall, and the area below it is not charged. During the operation process, the 4000V high voltage will not be transmitted to the frame, ensuring personnel safety.

[0024] The front of the upper test seat 4 after assembly is as Figure 13 shown; the back is as Figure 14 shown; the exploded view is as Figure 15 shown, and it includes screw C 4-1, screw D 4-2, connecting column 4-3, top column pressure plate 4-4, cavity pressure column 4-5, die limit column 4-6, alignment pin 4-7, upper seat base body 4-8, screw E 4-9, upper top column 4-10, spring B 4-11, upper spring cover plate 4-12, screw F 4-13, elastic mechanism 4-14, cavity pressure column spring 4-15, spring end cover 4-16, and screw G 4-17. Among them: Screw C 4-1 fixes the ejector pin pressure plate 4-4 on the upper seat base 4-8. The cavity ejector pin 4-5 is inserted into the cavity ejector pin mounting hole 4-8-4. The upper ejector pins 4-10 are respectively installed into the guide hole surfaces 4-8-5. The alignment pins 4-7 are respectively installed into the cylindrical surface III 4-8-6 and connected by screw E 4-9; the die closing limit posts 4-6 are combined with the upper seat base 4-8 through screws; the springs B 4-11 are respectively placed into the guide hole surfaces 4-8-5; the force-applying and conductive integrated elastic mechanism 4-14 is respectively placed into the elastic mechanism mounting hole 4-8-3; at this time, screw F 4-13 passes through the screw through-hole F4-12-2 and is screwed into the threaded hole F 4-8-9 to press the upper spring cover plate 4-12 onto the upper seat base 4-8; finally, the cavity ejector pin spring 4-15 is sleeved on the spring inner column 4-5-3-5, and the spring end cover 4-16 is pressed onto the upper spring cover plate 4-12 with screw G 4-17, then the upper test seat 4 can be assembled and completed.

[0025] Among them, for the connecting column 4-3, there are threaded holes 4-3-1 at both ends. One end passes through screw D 4-2, passes through the screw through-hole C 4-8-1 and is screwed into the threaded hole 4-3-1 and tightened. One end is connected to the screw through-hole A 1-3-1 through a screw, thereby fixing the entire upper test seat 4 to the upper test seat mounting plate 1-3.

[0026] Among them, for the cavity ejector pin 4-5, as Figure 16 shown, it includes screw H 4-5-1, upper pressure head 4-5-2, upper ejector pin base 4-5-3, tightening screw 4-5-4, limit square pin 4-5-5. For the upper ejector pin base 4-5-3, as Figure 17 shown, it includes threaded hole 4-5-3-1, pin hole 4-5-3-2, threaded hole 4-5-3-3, square hole 4-5-3-4, spring inner column 4-5-3-5, spring support surface 4-5-3-6. Screw H4-5-1 passes through the upper pressure head 4-5-2 and is screwed into the threaded hole 4-5-3-1 and tightened; the outer shape of the limit square pin 4-5-5 matches the outer shape of the square hole 4-5-3-4. The limit square pin 4-5-5 is inserted into the square hole 4-5-3-4 and a section leaks out symmetrically at both ends, and then the tightening screw 4-5-4 is screwed into the threaded hole 4-5-3-3 to tighten the limit square pin 4-5-5 inside the upper ejector pin base 4-5-3; the pin hole 4-5-3-2 matches the pin hole at the corresponding position of the upper pressure head 4-5-2, and the two can be positioned by using a cylindrical pin; the cavity ejector pin spring 4-15 can be sleeved outside the spring inner column 4-5-3-5, and one end of the cavity ejector pin spring 4-15 abuts against the spring support surface 4-5-3-6 to limit the cavity ejector pin spring 4-15.

[0027] Among them, for the upper ejector pin 4-10, as Figure 18As shown, the material is insulating and hard ceramic, including a working surface 4-10-1, a limiting surface 4-10-2, a guiding surface 4-10-3, and a spring thrust surface 4-10-4. During assembly, the guiding surface 4-10-3 matches the guiding hole surface 4-8-5 and is inserted into the guiding hole surface 4-8-5 for smooth sliding; the working surface 4-10-1 is a smooth plane, which presses against the inner conductor of the product during operation to apply pressure to the inner conductor; the spring thrust surface 4-10-4 contacts the rear spring B 4-11; the spring B 4-11 is in a compressed state during assembly. Therefore, when the limiting surface 4-10-2 is in its normal state, it presses against the pressing plate plane 4-4-1. When an external force is applied to the working surface 4-10-1, the spring B 4-11 is further compressed, and the entire ejector pin 4-10 retracts, but it always moves within the guiding hole surface 4-8-5. The limiting surface 4-10-2 separates from the pressing plate plane 4-4-1, and the axial movement range of the ejector pin 4-10 is limited by the pressing plate plane 4-4-1.

[0028] Among them, the alignment pin 4-7, as Figure 19 shown, is made of wear-resistant and hard metal, including a guiding inclined surface 4-7-1, a positioning cylindrical surface I 4-7-2, an anti-rotation hole 4-7-3, a positioning cylindrical surface II 4-7-4, and a threaded hole 4-7-5. During assembly, the positioning cylindrical surface II 4-7-4 is inserted into the cylindrical surface III 4-8-6, and their dimensions match each other; the screw E 4-9 passes through the hole on the back of the cylindrical surface III 4-8-6 and is screwed into the threaded hole 4-7-5 to tightly combine the two alignment pins 4-7 and the upper seat base 4-8; when tightening the screw E 4-9, the alignment pin 4-7 may rotate together. At this time, an inner hexagon wrench with a suitable size is inserted into the anti-rotation hole 4-7-3 to provide a counter torque; the positioning cylindrical surface I 4-7-2 will be inserted into the inner hole of the lower test seat positioning sleeve 3-9 during operation to position the upper test seat 4 and the lower test seat 3 when they are combined. During operation, it also detects and monitors whether the combined external position is appropriate. Once the position shifts, the alignment pin 4-7 cannot be inserted into the inner hole of the lower test seat positioning sleeve 3-9, and the control system of the mechanism will issue an alarm; the guiding inclined surface 4-7-1 is a smooth conical surface, which provides good guidance for the entire alignment pin 4-7 to combine with the lower test seat positioning sleeve 3-9; the positioning cylindrical surface I 4-7-2 and the positioning cylindrical surface II 4-7-4 require high coaxiality to prevent positioning errors caused by axial offset.

[0029] Among them, the elastic mechanism 4-14, as Figure 20 shown, includes a limiting cover 4-14-1, etc. Among them, the upper seat base 4-8, as Figure 21As shown in the figure, it includes screw through-hole C4-8-1, screw through-hole D 4-8-2, elastic mechanism mounting hole 4-8-3, cavity pressing column mounting hole 4-8-4, guiding hole surface 4-8-5, cylindrical surface Ⅲ 4-8-6, base plane 4-8-7, threaded hole E 4-8-8, threaded hole F 4-8-9, and pin hole 4-8-10. The elastic mechanism mounting hole 4-8-3 is a stepped hole with a concave platform at the upper part. The elastic mechanism 4-14 also has a corresponding convex ring. The outer diameter dimensions of the mounting part of the elastic mechanism mounting hole 4-8-3 and the elastic mechanism 4-14 match, and the depth of the concave platform matches the height of the convex ring. After installation, the upper spring cover plate 4-12 presses the convex ring into the concave platform to limit its axial movement; the cavity pressing column mounting hole 4-8-4 matches the outer shape of the cavity pressing column 4-5. The cavity pressing column 4-5 is inserted into the cavity pressing column mounting hole 4-8-4 and slides smoothly. The length of the limit square pin 4-5-5 is wider than the width of the cavity pressing column mounting hole 4-8-4, and its existence limits the limit of the downward movement of the cavity pressing column 4-5; the base plane 4-8-7 is a plane. The screw F 4-13 passes through the screw through-hole F4-12-2 and is screwed into the threaded hole F 4-8-9 to press the upper spring cover plate 4-12 on the base plane 4-8-7 and fit it flatly; the screw G 4-17 passes through the threaded through-hole 4-16-2 and the screw through-hole E4-12-1 and is screwed into the threaded hole E 4-8-8 to tightly press the spring end cover 4-16 on the surface of the upper spring cover plate 4-12; 2 matching cylindrical pins are installed in the pin hole 4-8-10, and the position and size match the positioning pin hole 4-12-7, which can determine the relative position between the upper seat base 4-8 and the upper spring cover plate 4-12.

[0030] Among them, the spring end cover 4-16, as Figure 22 shown, is made of insulating material and includes a cavity pressing column avoidance hole 4-16-1, a threaded through-hole 4-16-2, a conductive pin pressing hole 4-16-3, a bonding end face 4-16-4, an inner plane 4-16-5, and an inner surface of the concave platform 4-16-6. The cavity pressing column avoidance hole 4-16-1 is slightly larger than the inner spring column 4-5-3-5. When the cavity pressing column 4-5 moves up and down during operation, the inner spring column 4-5-3-5 can slide smoothly in the cavity pressing column avoidance hole 4-16-1. At the same time, the outer diameter of the cavity pressing column avoidance hole 4-16-1 is smaller than the outer diameter of the spring, so the cavity pressing column spring 4-15 is sleeved on the inner spring column 4-5-3-5 and its upper end abuts against the inner plane 4-16-5; the conductive pin pressing hole 4-16-3 is a stepped hole, and the inner diameter of the concave platform is slightly larger than the outer diameter of the limit cover 4-14-1. During assembly, the upper surface of the limit cover 4-14-1 abuts against the inner surface of the concave platform 4-16-6, and the through-hole diameter of the conductive pin pressing hole 4-16-3 is completely sufficient to pass through the upper conductive pin of the elastic mechanism 4-14; there are 4 bonding end faces 4-16-4, which are pressed on the upper surface of the upper spring cover plate 4-12 during assembly.

[0031] Among them, the top pillar pressing plate 4-4, as Figure 23 shown, is made of insulating sheet material and includes a pressing plate plane 4-4-1, an upper top pillar through hole 4-4-2, a cavity pressing pillar through hole 4-4-3, a screw through hole G4-4-4, and a mating pin through hole 4-4-5. The diameter of the upper top pillar through hole 4-4-2 is slightly larger than the diameter of the lower cylindrical surface of the upper top pillar 4-10 and smaller than the outer diameter of the guiding surface 4-10-3. Therefore, it can limit the upper top pillar 4-10; the cavity pressing pillar through hole 4-4-3 is an avoidance hole for the cavity pressing pillar 4-5; its shape is similar to the outer shape of the cavity pressing pillar 4-5 in order to maximize the shielding of the exposed area of the lower end surface of the upper seat base 4-8; the screw C 4-1 passes through the screw through hole G4-4-4 and is screwed into the corresponding threaded hole on the back of the upper seat base 4-8 to tightly combine the two; the outer diameter of the mating pin through hole 4-4-5 is slightly larger than the positioning cylindrical surface II 4-7-4, mainly to avoid the mating pin 4-7.

[0032] Among them, the upper spring cover plate 4-12, as Figure 24 shown, is made of insulating sheet material and includes a screw through hole E4-12-1, a screw through hole F4-12-2, an upper top pillar avoidance hole 4-12-3, an exhaust hole 4-12-4, an elastic mechanism avoidance hole 4-12-5, a screw avoidance hole 4-12-6, a positioning pin hole 4-12-7, and a limit square pin avoidance notch 4-12-8. The outer shape of the upper top pillar avoidance hole 4-12-3 matches the outer shape of the cavity pressing pillar 4-5, mainly to avoid the cavity pressing pillar 4-5; the exhaust hole 4-12-4 is a through hole, and its diameter is much smaller than the outer diameter of the guiding surface 4-10-3. Its main function is to exhaust the air in the guiding hole surface 4-8-5 during the upward movement of the upper top pillar 4-10; the outer diameter of the elastic mechanism avoidance hole 4-12-5 is slightly larger than the positioning outer diameter of the elastic mechanism 4-14 and smaller than the diameter of the corresponding convex ring in the middle of the elastic mechanism 4-14. Therefore, it can press the elastic mechanism 4-14 in the elastic mechanism installation hole 4-8-3 for limiting; the screw avoidance hole 4-12-6 corresponds to the position of the screw E 4-9, aiming to avoid the need to disassemble the upper spring cover plate 4-12 when installing the screw E 4-9; the limit square pin avoidance notch 4-12-8 mainly avoids the limit square pin 4-5-5.

[0033] The telescopic electrode 5, after assembly, is as Figure 26 shown; the exploded view is as Figure 28 shown, and it includes an electrode base 5-1, a conductive needle pressing block 5-2, a conductive needle 5-3, a screw I 5-4, a telescopic block 5-5, a small cover plate 5-6, a screw J 5-7, a nut B 5-8, an adjusting screw 5-9, a rear cover plate 5-10, a screw K 5-11, and a spring C 5-12; Among them, the conductive pin 5-3 is placed into the telescopic block 5-5, the conductive pin pressing block 5-2 is covered, and it is tightened by the screw I 5-4; the whole is placed into the electrode base 5-1, the small cover plate 5-6 is covered, and the small cover plate 5-6 is tightened on the electrode base 5-1 by the screw J 5-7; the spring C 5-12 is inserted into the corresponding hole of the telescopic block 5-5 from the rear, and the other end is inserted into the corresponding blind hole of the rear cover plate 5-10, and the rear cover plate 5-10 is locked on the electrode base 5-1 by the screw K 5-11; the adjusting screw 5-9 is screwed into the corresponding threaded hole of the small cover plate 5-6, and the head extends into the limiting groove 5-5-2, and is tightened by the nut B 5-8 to fix the depth of the adjusting screw 5-9 extending into the limiting groove 5-5-2, so that the telescopic block 5-5 can slide smoothly and the telescopic block 5-5 can be restricted from coming out.

[0034] Among them, the telescopic block 5-5, as Figure 27 shown, includes a screw through hole H5-5-1, a limiting groove 5-5-2, a middle through hole 5-5-3, a spring limiting blind hole 5-5-4, a conductive pin limiting table 5-5-5, a conductive pin installation groove 5-5-6, a guiding tail end 5-5-7, and a top plane 5-5-8. The screw through hole H5-5-1 is used to pass through the screw I 5-4; the limiting groove 5-5-2 is a waist-shaped blind groove, the width of which is slightly wider than that of the adjusting screw 5-9, and the length is appropriate, which can enable the telescopic block 5-5 to slide and limit the moving stroke of the telescopic block 5-5; the middle through hole 5-5-3 is a through hole for passing through a wire; the spring limiting blind hole 5-5-4 is a blind hole for limiting and installing the spring C 5-12; the conductive pin limiting table 5-5-5 is the table surface of a stepped hole, which cooperates with the convex platform on the conductive pin to limit the axial movement of the conductive pin 5-3; the conductive pin installation groove 5-5-6 is a semi-circular groove, the diameter of which matches the outer diameter of the conductive pin 5-3, and is used for installing the conductive pin 5-3; the guiding tail end 5-5-7 has a shape matching that of the guiding inner groove 5-1-2, slides smoothly, and provides guiding and limiting functions; when the lower test seat 3 moves to a certain position, the lower test seat substrate 3-3 will contact the top plane 5-5-8 and push the telescopic block 5-5 to move.

[0035] Among them, the electrode base 5-1, as Figure 29 shown, includes a screw through hole I5-1-1, a guiding groove 5-1-2, a threaded hole 5-1-3, and a threaded hole 5-1-4. The screw through hole I5-1-1 is used to connect the whole telescopic electrode to the frame 1, and the guiding groove 5-1-2 has a shape matching that of the guiding tail end 5-5-7; the screw J 5-7 passes through the corresponding hole of the small cover plate 5-6 and is screwed into the threaded hole 5-1-3 to fix the small cover plate 5-6; the screw K 5-11 passes through the through hole 5-10-2 to fix the rear cover plate 5-10 to the electrode base 5-1.

[0036] Among them, the rear cover plate 5-10, as Figure 30As shown, it includes wire vias 5-10-1, via 5-10-2, and spring blind via 5-10-3; wire via 5-10-1 is coaxial with the middle through hole 5-5-3 and is used to pass through wires; spring blind via 5-10-3 is used to install the other end of spring C 5-12.

[0037] For the entire telescopic electrode 5, there are two telescopic parts. The first is the telescopic block 5-5, which can slide back and forth. The other is the conductive pin 5-3 itself. When the lower test seat 3 moves to directly below the upper test seat 4 during the test, the lower test seat 3 first contacts the top end of the conductive pin 5-3 and compresses the spring inside the conductive pin 5-3 itself. When it continues to move, the lower test seat 3 contacts the top plane 5-5-8 and compresses spring C 5-12. During normal operation, spring C 5-12 is compressed by a small amount. When the power is off and the mechanism is intervened by external forces manually, spring C 5-12 can be further compressed until the telescopic block 5-5 is completely retracted into the electrode base 5-1. The elastic force relationship is that the elastic force of the conductive pin 5-3 is less than that of spring C 5-12, so as to protect the fragile conductive pin 5-3 from being damaged by external forces.

[0038] The product 2 to be tested or the pins to be pressed, such as Figure 25 As shown, it includes: inner conductor 2-1, cavity 2-2, and central conductor 2-3. The inner conductor 2-1 is a stepped cylindrical structure with one end thick and the other end thin, and includes: large end of the inner conductor 2-1-1; the cavity 2-2 includes: bottom surface of the cavity 2-2-1, top surface of the product 2-2-2.

[0039] The main functions of the high-efficiency mechanism of the present invention are: ① protruding the large end 2-1-1 of the inner conductor a certain required distance from the bottom surface 2-2-1 of the cavity, ② testing the insulation ability of the central conductor 2-3 relative to the cavity 2-2 under a certain voltage (up to 4000V), and these two actions need to be carried out simultaneously, saving operation time and meeting personnel safety.

[0040] After the lower test seat 3 is assembled, the height difference between the small end face 3-6-3 and the upper plane 3-3-5 can be adjusted by adjusting the height of the stud 3-2 to control the distance that the large end 2-1-1 of the inner conductor protrudes from the bottom surface 2-2-1 of the cavity. During the withstand voltage test, the lower test seat substrate 3-3 in the lower test seat 3 is charged, and the rest of the components are not charged, thus protecting personnel safety.

[0041] After the upper test socket 4 is assembled, the cavity compression post 4-5 is elastic under the action of the cavity compression post spring 4-15 and can elastically expand and contract a certain distance. The purpose is to accommodate the height tolerance of the product top surface 2-2-2 + the non-parallel error between the lower test socket 3 and the upper test socket 4 caused by the component tolerance, and ensure that the product top surface 2-2-2 of each product can be applied with pressure; the upper ejector post 4-10 can also elastically expand and contract. The elastic force of spring B 4-11 is greater than the force required to eject the inner conductor 2-1. During operation, the working surface 4-10-1 abuts against the upper end of each inner conductor 2-1, and the large end 2-1-1 of the inner conductor is ejected under the elastic force to fit on the small end face 3-6-3, thus ensuring that the large end 2-1-1 of the inner conductor protrudes from the cavity bottom surface 2-2-1 by a certain required distance; because the upper ejector post 4-10 can elastically expand and contract, the inner conductor 2-1 of each product can be applied with pressure; the lower end of the elastic mechanism 4-14 as a whole also elastically expands and contracts, but structurally it is a two-layer expansion and contraction. The outer shell is a conductive sleeve that needs to be in 100% contact with the central conductor 2-3 to transfer electricity. However, the central conductor 2-3 is very soft, so the conductive sleeve has very little elasticity. The inner core is a steel ejector pin that needs to transfer the same elastic force as spring B 4-11 to the top end of one of the inner conductors 2-1 to act as the same function as the upper ejector post 4-10. The elastic force of spring B 4-11 is greater than that of the conductive sleeve of the elastic mechanism 4-14, and there is a height difference between the top end of the inner conductor 2-1 and the central conductor 2-3. This requires that when the elastic mechanism 4-14 moves down as a whole with the upper test socket 4, the inner and outer two layers expand and contract independently and always maintain the elastic force; after the upper test socket 4 is assembled, it is installed on the upper test socket mounting plate 1-3 through the threaded hole A 4-3-1.

[0042] During use, the product 2 is placed in the corresponding pit of the lower test socket 3. The servo motor 1-8 rotates, driving the conveying plate 1-2 and the lower test socket 3 to move under the lower test socket 4, and then stops. The upper test socket 4 presses down, the force is transmitted to the inner conductor 2-1 and the product top surface 2-2-2, and the voltage is transmitted to the cavity bottom surface 2-2-1 and the central conductor 2-3, so as to perform the withstand voltage and leveling operations on the product. After completion, the lower test socket 3 and the upper test socket 4 return to the original positions, completing a set of operation processes, and this action process is cycled.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
