Description

Technical Field

[0001] This invention relates to the field of testing technology for microwave products powered by insulators, and more specifically, to a flexible pin, a manufacturing method thereof, and a power supply device for microwave products powered by insulators. Background Technology

[0002] Microwave products powered by insulators are widely used in microsystems. As these products become more complex and smaller, the diameter and spacing of the insulators are decreasing, and their numbers are increasing. Therefore, providing stable, reliable, and efficient power to these products during testing is becoming increasingly challenging.

[0003] In existing technologies, there are two main types of power supply methods: One type is a dedicated power supply device, which consists of a rectangular connector, circuit pieces, wires, and a base. This type of power supply device can conveniently and quickly power the product, but it has the following problems: each product is equipped with a dedicated fixture, and the number of fixtures is proportional to the number of products, resulting in high management complexity and high production costs; the production process requires frequent disassembly and assembly, and the fixture accessories and product insulators are easily damaged, resulting in high maintenance costs and affecting product quality.

[0004] Another type is a universal power supply device using self-made pins, consisting of wires, pins, and heat shrink tubing. This power supply device can power a variety of products and is universal, but it has the following problems: Each test requires manual insertion and connection of the pins and insulators one by one according to the product's power supply relationship. Frequent physical insertion and removal not only consumes testing time, but manual connection is also prone to errors, which poses a risk of burning out the internal core of the product; frequent insertion and removal makes the connection between the pin and the wire prone to breakage, and once broken, it cannot be repaired. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a power supply device for microwave products with flexible pins, a manufacturing method, and insulator feeding, which does not require one-to-one assembly with the product, has universality, and results in low production, management, and maintenance costs, is reusable, and is easy to operate; The solution adopted by this invention to solve the technical problem is: on the one hand: The present invention provides an elastic pin, comprising a copper foil, a conductive rubber post coaxially arranged with and disposed on the copper foil, a copper ring coaxially disposed outside the conductive rubber post, and an insulating rubber layer disposed outside the copper ring.

[0006] on the other hand: This invention provides a method for preparing the elastic insert as described above, specifically including the following steps: Step S1: Clean the copper foil; Step S2: Apply a layer of dry film onto the copper foil; Step S3: Perform photolithography on the dry film according to the cross-sectional dimensions of the copper ring; Step S4: Electroplating copper at the exposed copper foil area after photolithography to form a copper ring; Step S5: Repeat steps S2 to S4 to achieve the required thickness of the copper ring; Step S6: Remove all the dry film from the copper foil; Step S7: Fill the copper ring with conductive rubber to form a conductive rubber pillar; Step S8: Fill the outer area of ​​the copper ring with insulating rubber to form an insulating rubber layer; Step S9: Level the surfaces of the conductive rubber pillar, insulating rubber layer, and copper ring; Step S10: Cold cutting to form a single flexible pin.

[0007] On the other hand: A power supply device for an insulator-fed microwave product includes a fixed plate, a YZ moving structure disposed on the fixed plate and slidingly engaged with the fixed plate along the Y and Z axes, multiple clamping mechanisms disposed on the YZ moving structure and moving along the X axis, an elastic connection structure disposed on each clamping mechanism, and a rectangular connector disposed on the fixed plate and connected to the elastic connection structure.

[0008] Specifically, in use, first place the product to be tested on the fixing plate, so that it is close to the boss on the fixing plate, and then connect the power supply device to the rectangular connector; Subsequently, based on the distance between the insulator and the fixed plate of the product under test, the YZ moving structure is moved and adjusted along the Z-axis to make the distance between the elastic connection structure and the fixed plate meet the requirements for the connection between the insulator and the elastic pin. Then, based on the position of the insulator, the YZ moving structure is controlled to move along the Y-axis to adjust the distance between the elastic pin and the insulator, so that the two can be inserted. The clamping mechanism is moved along the X-axis according to the distance between adjacent insulators, so that the distance between two adjacent sets of elastic connection structures matches the distance between adjacent insulators; Finally, simply insert the insulator into the flexible connection structure. Compared with existing technologies, this application can achieve power supply for a variety of tested products by controlling the movement of the elastic pin in the X, Y, and Z axes, which has good versatility. The number of elastic connection structures can be increased or decreased according to the number of insulators; the operation is simple and convenient.

[0009] In some possible implementations, in order to effectively realize the movement of the YZ moving structure along the Y-axis and Z-axis directions, the position of the elastic connection structure can be adjusted in the Y-axis and Z-axis directions; The fixed plate is provided with two sets of Y-axis sliding grooves arranged along the Y-axis direction; the YZ moving structure includes a moving plate arranged on the fixed plate, a YZ adjusting bolt with one end passing through the Y-axis sliding groove and fitted inside the moving plate, and an adjusting nut that is screwed into the YZ adjusting bolt and used to adjust the moving plate along the Y-axis and Z-direction.

The copper foil end of the flexible pin is soldered onto the circuit board, and the other end is connected to the insulator of the product under test; the flexible pin is cylindrical.

[0013] In some possible implementations, the movable plate is provided with a through slot through which one end of a wire passes and is connected to a rectangular connector, and an abutment slot that abuts against a locking bolt and is provided along the X-axis.

[0014] In some possible implementations, a mounting plate for fixing a rectangular connector is provided on the fixed plate; the mounting plate is arranged parallel to the movable plate; the U-shaped clamp is provided on the side of the movable plate away from the mounting plate; and a boss for fixing the product under test is provided on the fixed plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention effectively connects insulator-fed microwave products to power supply devices through the cooperation of a fixed plate, a YZ moving structure, a clamping mechanism, and a rectangular connector. By adjusting the YZ moving structure along the Y and Z axes, and by coordinating the clamping mechanism with the YZ moving structure along the X axis, the position of the flexible pins can be adjusted in the XYZ three-axis directions. This allows the flexible pins to be positioned according to the specific location of the insulator, meeting the usage requirements of microwave products fed by insulators of different sizes and spacings. In this invention, the elastic pin is interconnected with the insulator through contact via a conductive rubber post. Compared with the prior art, which interconnects with the insulator via a pin, this method can effectively achieve rapid insertion and removal, is convenient to operate, and does not damage the component insulator. At the same time, because it adopts contact interconnection, it can be interconnected with insulators of different models and sizes, greatly improving the versatility of this invention. The flexible pin in this invention can be flexibly installed and removed according to the number of insulators in the product, meeting the usage requirements of microwave products fed by different numbers of insulators.

[0018] The present invention will now be described in detail.

[0019] like Figures 1-10 As shown: A power supply device for an insulator-fed microwave product includes a fixed plate 1, a YZ moving structure 2 disposed on the fixed plate 1 and slidingly engaged with the fixed plate 1 along the Y and Z axes, multiple clamping mechanisms 3 disposed on the YZ moving structures 2 and moving along the X axis, an elastic connection structure 4 disposed on each clamping mechanism 3, and a rectangular connector 5 disposed on the fixed plate 1 and connected to the elastic connection structure 4; the elastic connection structure 4 is connected to the product under test 100. In this application, the fixing plate 1 refers to a metal base plate that serves a fixing function; optionally, the fixing plate 1 is made of iron, copper, aluminum alloy, etc., and its shape is square, rectangle, L-shaped or other irregular polygon, etc. Specifically, in use, the product to be tested 100 is first placed on the fixing plate 1, so that it is close to the boss on the fixing plate, and the power supply equipment is connected to the rectangular connector 5. Based on the distance between the insulator 200 and the fixed plate 1 of the tested product 100, the distance between the elastic connection structure 4 and the fixed plate 1 is adjusted by moving the YZ moving structure 2 along the Z-axis direction to meet the connection requirements between the insulator 200 and the elastic connection structure 4. The YZ moving structure 2 is controlled to move along the Y-axis according to the position of the insulator 200, and the distance between the elastic connection structure 4 and the insulator 200 is adjusted. The clamping mechanism 3 moves along the X-axis according to the distance between adjacent insulators 200, so that the distance between two adjacent sets of elastic connection structures 4 matches the distance between adjacent insulators 200. Finally, simply insert the insulator 200 into the elastic connection structure 4; Compared with the prior art, this application can achieve power supply for a variety of tested products 100 by controlling the movement of the elastic connection structure 4 in the X, Y and Z axes, which has good versatility. The number of clamping mechanisms 3 and elastic connection structures 4 can be increased or decreased according to the number of insulators 200; the operation is simple and convenient. Furthermore, the rectangular connector 5 refers to a connector that is basically rectangular in shape and has a basically rectangular mating surface. It is a low-frequency contact connector and can be divided into two types according to the connection characteristics: straight-insertion type and locking type. The rectangular connector 5 is divided into 9-pin and 15-pin types according to the usage requirements. Optionally, the rectangular connector 5 is a CA type, CB type, CD type, CH type, J type connector, etc.

[0020] In some possible implementations, in order to effectively connect the product under test 100 to the power supply equipment through the elastic connection structure 4 and to supply power to the product under test 100, the elastic connection structure 4 includes an elastic connector 41 mounted on the clamping mechanism 3; the elastic connector 41 is connected to the rectangular connector 5 through a wire 42. Specifically, the elastic connector 41 is connected to the conductor 42 and the insulator 200 of the product under test 100 respectively, so as to realize the power supply to the product under test 100; The conductor 42 refers to an insulated conductor used to transmit current or signals; optionally, the conductor 42 refers to a copper conductor, an aluminum conductor, or an alloy conductor, etc.

[0021] In some possible implementations, in order to effectively realize the movement of the YZ moving structure 2 along the Y-axis and Z-axis directions, the position of the elastic connection structure 4 can be adjusted in the Y-axis and Z-axis directions; like Figure 1 , Figure 3 , Figure 5 As shown, two sets of Y-axis sliding grooves 21311 are provided on the fixed plate 1 along the Y-axis direction; the YZ moving structure 2 includes a moving plate 21 provided on the fixed plate 1, a YZ adjusting bolt 22 with one end passing through the Y-axis sliding groove 21311 and fitted inside the moving plate 21, and an adjusting nut 23 screwed to the YZ adjusting bolt 22 and used to adjust the moving plate 21 along the Y-axis and Z-axis; wherein, the axial direction of the YZ adjusting bolt 22 is arranged along the Z-axis direction; Furthermore, in order to effectively adjust the position of the moving plate 21 in the Z-axis direction by adjusting the nut 23; like Figure 4 As shown, the adjusting nut 23 includes a first nut 231, a second nut 232, and a third nut 233 that are screwed into the YZ adjusting bolt 22 and arranged sequentially along its axial direction; the moving plate 21 is located between the first nut 231 and the second nut 232 and is used to adjust the moving plate 21 along the Z-axis and to lock and fix the moving plate 21. The nut 233 engages with the nut of the YZ adjusting bolt 22 and is used to adjust the moving plate 21 along the Y-axis and to lock the YZ adjusting bolt 22. Specifically, the nut of the YZ adjusting bolt 22 is located on the side of the fixed plate 1 away from the moving plate 21; the width of the nut is greater than the width of the Y-direction slide groove 21311; when the moving block moves along the Y-axis, the nut 233 will not abut against the top surface of the fixed plate 1. At this time, the nut 233 and the nut will not abut against the fixed plate 1, so the YZ adjusting bolt 22 can be moved along the length of the Y-direction slide groove 21311, driving the moving plate 21 to move along the Y-axis; after moving to the designated position, the nut 233 is tightened so that the nut 233 abuts against the fixed plate 1, and the YZ adjusting bolt 22 is locked and fixed in cooperation with the nut. When the movable plate 21 is adjusted along the Z-axis, a gap will be formed between the nut 231 and the movable plate 21, resulting in a non-aggressive fit. Then, the nut 232, located at the bottom of the movable plate 21 and used to support the movable plate 21, will be turned so that the nut 232 moves along the axial direction of the YZ adjusting bolt 22, thereby adjusting the positional relationship between the movable plate 21 and the fixed plate 1 in the Z-axis direction until the requirements are met. Then, the nut 231 will be brought into contact with the top surface of the movable plate 21. The movable plate 21 will be fixed on the YZ adjusting bolt 22 by the fit between the nut 231 and the nut 232 and will not move along the Z-axis. Furthermore, a support boss 6 is provided at the bottom of the fixing plate 1 to assist in fixing the plate 1.

[0022] In some possible implementations, in order to effectively control the movement and adjustment of the elastic connecting structure 4 along the X-axis direction by means of the clamping mechanism 3; like Figure 4 , Figure 9 As shown, the clamping mechanism 3 includes a U-shaped clamp 31 disposed on the moving plate 21 and sliding along the X-axis with the moving plate 21, and a locking bolt 32 disposed on the U-shaped clamp 31 and having one end in contact with the moving plate 21; the elastic connector 41 is mounted on the U-shaped clamp 31; the axial direction of the locking bolt 32 is arranged along the Z-axis. Furthermore, the U-shaped clip 31 refers to a metal structure in the shape of a U. Optionally, the material of the U-shaped clip 31 is iron, copper, aluminum alloy, etc.

[0023] In some possible implementations, in order to effectively achieve the installation of the elastic connection structure 4; like Figure 9 As shown, the movable plate 21 is provided with a sliding groove 213 on the side near the product 100 being tested, which slides and engages with the U-shaped clamp 31; the U-shaped clamp 31 includes a movable part 311 that is inserted into the sliding groove 213 and slides and engages with the sliding groove 213, a fixed part 312 that is parallel to the sliding part and screwed to the locking bolt 32, and a connecting part 313 that connects the fixed part 312 and the movable part 311 to form a U-shaped structure; The opening of the U-shaped structure is located near the side of the movable plate 21; the fixing part 312 is arranged parallel to the fixing plate 1 and located above the movable plate 21.

[0024] In some possible implementations, in order to effectively connect the resilient connector 41 to the conductor 42 and the insulator 200; like Figure 4 As shown, the elastic connector 41 includes a coaxial connector 411 connected to the end of the wire 42 away from the rectangular connector 5 and soldered to the connecting part 313, a circuit piece 412 pasted on the side of the connecting part 313 away from the moving plate 21 and connected to the coaxial connector 411, and an elastic pin 413 soldered to the circuit piece and connected to the insulator 200 of the product under test 100; further, the connecting part 313 is provided with a mounting hole for mounting the coaxial connector 411; Circuit chip 412 refers to a transmission line that provides a path for signal transmission. Optionally, the transmission line can be a parallel twin line, a coaxial line, a microstrip line, a stripline, etc. A coaxial connector 411 is a component used to connect microwave devices or circuits. It typically consists of two coaxial metal conductors and a dielectric insulator, and is mainly used to transmit microwave signals, direct current, and control signals. Optionally, the coaxial connector 411 can be a glass coaxial connector, a ceramic coaxial connector, a polytetrafluoroethylene (PTFE) coaxial connector, etc. In order to effectively connect the insulator 200 and the flexible pin 413; such as Figure 7 , Figure 8 As shown, the elastic pin 413 is cylindrical and includes a copper foil 4131 soldered on the circuit piece 412, a conductive rubber post 4132 coaxially arranged with and disposed on the copper foil 4131, a copper ring 4133 coaxially disposed outside the conductive rubber post 4132, and an insulating rubber layer 4134 coaxially disposed outside the copper ring 4133 and located on the copper foil 4131; one end of the elastic pin 413 away from the copper foil 4131 is connected to the insulator 200 of the product under test 100100.

[0025] The copper ring 4133 is coaxially disposed on the outside of the conductive rubber post 4132 and is in communication with the copper foil 4131; the copper ring 4133, the conductive rubber post 4132, and the insulating rubber layer 4134 are all disposed on the side of the copper foil 4131 away from the circuit piece 412, and the three are coaxially disposed, with the ends of the copper ring 4133, the conductive rubber post 4132, and the insulating rubber layer 4134 away from the copper foil 4131 on the same plane; Furthermore, the conductive rubber column 4132 is made of conductive rubber, and the guide rubber is a colloid composed of rubber and conductive particles. After curing, the conductive particles are brought into contact by pressure to achieve good conductivity. Optionally, the conductive rubber is aluminum silver-plated silicone rubber, silver-plated silicone rubber, copper silver-plated silicone rubber, graphite silicone rubber, etc.

[0026] The insulating rubber layer 4134 is made of insulating rubber, which is a material with high resistivity and poor conductivity. It can be solid or liquid rubber or resin. After molding, it has good electrical insulation properties and a certain amount of elastic compression. Optionally, the insulating rubber is one or more of silicone rubber, butadiene rubber, ethylene propylene rubber, polyurethane rubber, etc.

[0027] The specific steps involved in manufacturing this flexible insert 413 are as follows: Step S1: Clean copper foil 4131; Step S2: Apply a layer of dry film 4130 onto the copper foil 4131; Step S3: Perform photolithography on the dry film 4130 according to the cross-sectional dimensions of the copper ring 4133; Step S4: Electroplating copper at the exposed copper foil 4131 position after photolithography to form a copper ring 4133; Step S5: Repeat steps S2 to S4 to achieve the required thickness of copper ring 4133; Step S6: Remove all the dry film 4130 from the copper foil 4131; Step S7: Fill the copper ring 4133 with conductive rubber to form a conductive rubber pillar 4132; Step S8: Fill the outer area of ​​the copper ring 4133 with insulating rubber to form an insulating rubber layer 4134; Step S9: Level the surfaces of the conductive rubber column 4132, the insulating rubber layer 4134, and the copper ring 4133; Step S10: Cold cutting to form a single flexible pin 413.

[0028] When the flexible pin 413 is used to interconnect with the insulator 200, it is only necessary to ensure that the insulator 200 and the conductive rubber post 4132 are in contact after insertion. Compared with the prior art, the connection method is simplified and the damage to the insulator 200 caused by repeated insertion and removal is avoided. At the same time, compared with the pin interconnection method in the prior art, this method will greatly reduce the installation accuracy requirements and greatly improve the work efficiency. The contact interconnection method allows the flexible pin 413 to be interconnected with insulators 200 of different sizes, and also enables quick insertion and removal.

[0029] In some possible implementations, such as Figure 3 , Figure 5As shown, the movable plate 21 is provided with a through groove 211 through which one end of the wire 42 passes and is connected to the rectangular connector 5, and an abutting groove 212 that abuts against the locking bolt 32 and is provided along the X-axis direction; Specifically, the abutment groove 212 is located on the side of the movable plate 21 away from the fixed plate 1, and is in the shape of a long strip; The fixing part 312 is provided with a threaded hole, and the locking bolt 32 is adapted to the threaded hole. One end of the locking bolt 32 passes through the threaded hole and extends into the abutting groove 212 and contacts and abuts against the bottom of the abutting groove 212. Since the end of the moving part 311 away from the connecting part is located in the sliding groove 213, when moving along the X-axis direction, the locking bolt 32 does not abut against the bottom of the abutting groove 212. At this time, the elastic connecting member 41 can be moved along the X-axis direction. After moving to the designated position, the locking bolt 32 abuts against the bottom of the abutting groove 212 to achieve fixation and restrict the movement of the U-shaped clamp 31 along the X-axis direction.

[0030] In some possible implementations, to facilitate the installation of the rectangular connector 5, a mounting plate for fixing the rectangular connector 5 is provided on the fixing plate 1; the mounting plate is arranged parallel to the moving plate 21; the U-shaped clamp 31 is located on the side of the moving plate 21 away from the mounting plate; Furthermore, the rectangular connector 5 is connected and fixed to the mounting plate by bolts; the rectangular connector 5 is installed on the side of the mounting plate away from the movable plate 21.

[0031] In some possible implementations, a boss 7 for fixing the product under test 100 is provided on the fixing plate 1. When the elastic pin 413 is inserted into the insulator 200 and fixed, the product under test 100 is fixed close to the boss 7 to prevent the product under test 100 from moving during the test. This fixture is an existing structure, mainly used to fix the product under test 100. Its internal structure will not be described in detail here.

[0032] The product models and process parameters involved in the power supply device design of this invention, such as the rectangular connector model 5, the coaxial connector model 411, the type and size of the circuit piece 412, the shape and size of the flexible pin 413, and the shape and size of the U-shaped clip 31, can be flexibly changed according to actual needs. All equivalent changes and modifications made within the scope of this invention are within the scope of protection claimed by this patent.
