Description

Technical Field

[0001] This invention relates to the fields of aerospace electrical connectors, inter-board high-voltage electrical connectors, and high-voltage connectors, specifically to a high-voltage transmission device inside spaceborne equipment. Background Technology

[0002] The design of space probes is complex, requiring division according to instrument functional modules. Probes are typically divided into sensors and electronics enclosures. The electronics enclosure usually houses multiple printed circuit boards (PCBs) in different locations. This spatially isolated modular design reduces noise interference and signal coupling between PCBs, effectively improving probe performance. However, signal exchange is necessary between different PCBs and between electronics and sensors. Signal transmission typically uses aerospace-grade inter-board electrical connectors. To avoid electromagnetic interference to other probes on the satellite platform, the probe's electronics and sensors are usually integrated, mounted in different locations within the same housing. The probe housing is typically a sealed enclosure made of metals such as magnesium or aluminum. The housing effectively shields the probe's internal signals from the outside; therefore, all internal signals from the electronics and sensors must be transmitted or wired within the housing. Signal transmission between boards and between sensors and electronics typically uses internal electrical connectors or more traditional lead-wire connections.

[0003] There are many types of space environment detectors, each with different requirements for electrical connectors. Major space environment detectors such as low-energy particle detectors, optical detectors, X-ray detectors, and high-energy particle detectors all require high-voltage power supplies (tens of thousands of volts) for their sensors to operate. Furthermore, the scientific data generated by these sensors is analog signal. Therefore, the electronics boxes for these detectors typically include a high-voltage circuit module and a scientific data acquisition module. High voltage is prone to discharge, which can easily cause sensor malfunctions and potentially damage the instrument. Simultaneously, the scientific data generated by the sensors in these detectors is analog signal with a small amplitude, making it highly susceptible to interference from high-voltage signals, leading to abnormal data. Therefore, high-voltage transmission is particularly crucial in the design of these detectors.

[0004] Miniaturization and lightweight design have become major development trends in aerospace probe development in recent years. Therefore, miniaturization and light weight have become important considerations for selecting aerospace electrical connectors. Furthermore, the harsh operating environment of aerospace probes places stringent requirements on the electrical connectors' resistance to high and low temperatures and vacuum environments. For space environment detectors such as low-energy particle detectors, optical detectors, X-ray detectors, and high-energy particle detectors, the inter-board electrical connectors must not only be resistant to high and low temperatures and vacuum environments, but also withstand high voltage.

[0005] Currently, there are no lightweight electrical connectors on the market capable of withstanding tens of thousands of volts. Therefore, the high-voltage transmission of space environment detectors such as low-energy particle detectors, optical detectors, X-ray detectors, and high-energy particle detectors all rely on traditional soldered high-voltage wires. In the early stages of instrument design, the detector undergoes numerous sensor and electronics assembly and disassembly tests. Each disassembly and reassembly requires soldering and desoldering the high-voltage solder joints. Repeated soldering can easily lead to the detachment of printed circuit board pads, and the soldering and desoldering also increases the difficulty of disassembling and assembling the instrument. Summary of the Invention

[0006] This invention addresses the problem of internal high-voltage transmission in current detectors by proposing a small-sized, lightweight (8g) aerospace-grade inter-board electrical connector capable of withstanding voltages above 10kV. This connector enables high-voltage transmission within the instrument, effectively preventing interference with other analog circuits or damage to the instrument due to improper soldering. Furthermore, it reduces the complexity of disassembling and assembling the detector's electronics box and sensors, significantly lowers the risk of pad detachment due to repeated soldering, improves the detector's safety and reliability, and expands the application areas of internal high-voltage electrical connectors.

[0050] Advantages of the electrical connector of this invention:

[0051] 1. This invention designs an inter-board electrical connector that can withstand voltages of up to 10kV to achieve high-voltage transmission within the instrument;

[0052] 2. This invention uses polyimide (YS20) material as the base of the electrical connector, which effectively improves the withstand voltage of the contacts and effectively reduces the weight of the contacts. Furthermore, this material has been used in orbit on multiple satellites and exhibits excellent insulation properties. Polyimide is a novel high-insulation material with high hardness and is relatively brittle, making it difficult to process and expensive. Currently, few electrical connectors on the market use polyimide as the base.

[0053] 3. This invention proposes a special structural design (grooves, vent holes, etc.) to increase the withstand voltage parameters of the electrical connector;

[0054] 4. The purpose of this invention is to solve the technical problem of high voltage transmission inside the detector; the invention uses high-insulation, low-density polyimide material as the insulating base of the electrical connector, which effectively improves the withstand voltage of the electrical connector, while reducing the weight and volume of the electrical connector, which is beneficial to the miniaturization design of the detector.

[0055] 5. This invention effectively improves the withstand voltage of electrical connectors through structural design and material selection, greatly reduces the complexity of disassembling and assembling detector electronics boxes and sensors, reduces the risk of solder pads falling off after multiple soldering of electronics box and the risk of high voltage transmission interfering with other analog circuits, and has a wide range of application needs in the field of board-to-board connectors, especially in the field of high voltage transmission inside space environment detectors.

[0056] 6. To improve the withstand voltage of the electrical connector, this invention uses polyimide bases to isolate the two cannulas at the socket end and the two pins at the plug end, ensuring that the dielectric material between the two cores is polyimide, a material with a high dielectric constant. The solder cup ends of the pins and cannulas are designed such that the polyimide base is higher than the solder cup, and the cannulas mating ends are designed such that the polyimide base fits tightly against the cannulas, thus increasing the dielectric constant between the two cores. An annular recess is designed on the outer edge of the pin through-hole at the pin mating end to increase the creepage distance. These designs effectively improve the withstand voltage between the two cores and reduce the overall size.

[0057] 7. This invention designs vent holes at the mating ends of the electrical connectors and grooves at the mating ends of the insertion tubes to ensure thorough venting after connector mating. This prevents residual gas inside the connector from causing low-pressure discharge of the transmitted high-voltage signal. The potting process uses vacuum-sealed adhesive and is performed under vacuum conditions to prevent residual gas from remaining inside the potting compound. Attached Figure Description

[0065] Detailed Implementation

[0066] The technical solutions provided by the present invention will be further illustrated below with reference to the embodiments.

[0067] The purpose of this invention is to overcome the problem of high-voltage transmission inside the detector.

[0068] This invention provides a high-voltage resistant miniature inter-board electrical connector device. Figure 1 is a docking diagram of the high-voltage transmission device inside the spaceborne equipment of this invention. The electrical connector is divided into a plug structure 1 (pin) and a socket structure 2 (tube). In use, the plug structure 1 and the socket structure 2 are used in pairs.

[0069] Both plug structure 1 and socket structure 2 consist of an insulator base, contact elements (pins, tubes), and a protective tube assembly.

[0070] Figure 2(a) is a schematic diagram of the pin 9, Figure 2(b) and Figure 2(c) are schematic diagrams of the plug structure 1 from two different angles, Figure 2(d) and Figure 2(e) are the side view and front view of the plug structure along the cross section, respectively; Figure 3(a) is a schematic diagram of the tube 14, Figure 3(b) is a schematic diagram of the socket structure 2, Figure 3(c) and Figure 3(d) are the side view and front view of the socket structure along the cross section, respectively; After potting, the pin welding cup 11 and the adjacent parts of the plug base third structure 8-3 are filled with potting compound; the tube welding cup 17 and the adjacent parts of the socket base third structure 6-3 are filled with potting compound.

[0071] The plug structure 1 includes a plug base 8 and a pin 9. The plug base 8 has a groove designed according to the shape of the pin 9, and at least two vent holes 5, two glue holes 4 and two M2 screw mounting holes 7 are designed on the side wall. The pin 9 is embedded into the plug base 8 by impact and glued and fixed to the plug base 8 and the pin 9 by glue through the glue holes 4.

[0072] The socket structure 2 includes a socket base 6, a plug tube 14, and a plug tube protective assembly 13. The socket base 6 has a groove designed according to the shape of the plug tube 4 and the plug tube protective assembly 13 after assembly. At least two vent holes 5, two glue holes 4, and two M2 screw mounting holes 7 are designed on the side wall. The plug tube 14 and the plug tube protective assembly 13 are assembled by tightening the threads. After the plug tube 14 and the plug tube protective assembly 13 are assembled, they are embedded into the socket base 6 by impact and glued and fixed through the glue holes.

[0073] Both the plug base 8 and the socket base 6 are made of high-insulation polyimide (YS20) material. This material has good electrical properties, corrosion resistance, fatigue resistance, high temperature resistance, wear resistance, impact resistance, low density, and long service life. It is widely used in the structural materials of aerospace probes.

[0074] The contacts (pin 9, cannula 14) are made of beryllium bronze (QSn4-3 Y), and the sheath assembly 13 is made of stainless steel (0Cr18Ni10Ti). Both beryllium bronze (QSn4-3 Y) and stainless steel (0Cr18Ni10Ti) are commonly used materials for high-grade electrical connectors. The sealant used for potting is EC 104 A / B, an epoxy adhesive commonly used in aerospace products.

[0075] The connector's structural design features an external insulating base. Pins 9, canopy 14, and sheath assembly 13 are first embedded into the base via impact, then secured a second time using potting compound. The connector has two contacts. One end of plug structure 1 is a pin-type contact, and one end of socket structure 2 is a canopy-type contact. Pin 9 mates with canopy 14. The other ends of both plug structure 1 and socket structure 2 have solder cup-type leads connected to solder joints. Both plug structure 1 and socket structure 2 have two M2 mounting screw holes on their bases, allowing them to be fixed to two parallel printed circuit boards.

[0076] Since the printed circuit board is installed inside the housing and the spacing between the boards is fixed, the electrical connectors between the boards experience very little force, and the screw strength requirements are low. Therefore, the mounting screws 3 of the electrical connector in this design are made of polyimide material, which can effectively prevent high voltage discharge to the metal screws. To prevent high voltage discharge between the two pins, the pins 9 and the tubes 14 of this electrical connector are specially designed.

[0077] Cannula 14 design: The outer layer of cannula 14 is tightly wrapped with polyimide material.

[0078] Pin 9 design: Pin 9 is surrounded by a polyimide material. A gap with the same diameter as the cannula 14 is left between pin 9 and the polyimide material to allow for pin-to-pin insertion. Circular grooves are designed on the sidewalls of the polyimide material to increase the creepage distance on the polyimide surface. This design effectively avoids the risk of discharge when the two cores transmit different high voltages.

[0079] In addition, to prevent residual gas inside the contacts after the electrical connector is mated, which could cause discharge during high-voltage transmission under low air pressure, the protective tube assembly 13, the socket base 6 and the plug base 8 are all designed with vent holes with a diameter of 1-1.5mm on their side walls, and the insertion tube (14) is designed with a slot with a width of 1-1.5mm on its side wall to ensure good vacuum inside the electrical connector when used in a vacuum state.

[0080] The wall thickness of the hollow cylinder is not less than 0.3 mm;

[0081] The diameter of the solid cylinder 10 is 0.7 mm;

[0082] The installation method of the electrical connector is as follows: the connection between the plug structure 1 and the socket structure 2 is a crimping and locking method, that is, the electronic box and the sensor or printed circuit board are assembled and then crimped and locked.

[0083] The schematic diagram of the electrical connector structure in this application is shown below. Figure 1 The electrical connector shown weighs only 8g.

[0084] The socket structure 2 inside the detector is fixed to the printed circuit board, such as... Figure 4 ; The plug structure 1 is fixed to the metal platform inside the detector sensor, such as Figure 5 As shown, Figure 6 The diagram shows the inter-board electrical connector of this application installed at the interface between the detector's internal electronics box and the sensor. The plug is mounted on the base of the housing with screws, and the socket is fixed to the printed circuit board with screws.

[0085] In this implementation case, the performance of the electrical connector was tested, including the following tests:

[0086] 1. Atmospheric pressure high and low temperature power-on test: Temperature range: -35℃~+60℃, electrical connector is assembled inside the detector, high voltage transmission range: 0~-2000V.

[0087] 2. Thermal vacuum power-on test: Temperature range: -35℃~+60℃, electrical connector is assembled inside the detector, high voltage transmission range: 0~-6000V.

[0088] 3. Rated withstand voltage test: Temperature: +85℃, the electrical connector is installed separately in the housing, the voltage difference between the two contacts increases in a step-like manner from 1000V, 2000V, 3000V... The high voltage and current of the contacts are monitored using a high voltage probe and current clamp, and the discharge phenomenon is monitored by single-pulse triggering method of oscilloscope. The high voltage is maintained for 60 minutes under each step. According to the test results, the withstand voltage between the two contacts of the electrical connector is better than 10kV.

[0089] As can be seen from the above detailed description of the present invention, the present invention uses high-insulation, low-density polyimide material as the insulating base of the electrical connector, while increasing the dielectric constant between the two cores and increasing the creepage distance in the design, and setting special designs such as venting holes on the connector, which effectively improves the withstand voltage value of the electrical connector, while reducing the weight and volume of the electrical connector, which is beneficial to the miniaturization design of the detector.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
