[0001] This invention relates to the field of electrical connectors, and more particularly to an aviation electrical connector assembly. Background Technology

[0002] Aviation electrical connectors are indispensable key components in aircraft electrical systems, undertaking the important tasks of signal transmission and power distribution. Their contact reliability is directly related to the safety and success of flight missions.

[0003] For example, the invention patent with application number CN202410652230.X discloses an aerospace electrical connector, including a female plug structure and a male plug structure.

Both the female plug structure and the male plug structure have external threads on their outer wall surfaces, and are provided with threaded sleeves two.

[0004] The above cases still have the following shortcomings: For example, during extravehicular activities, astronauts need to wear heavy extravehicular spacesuit gloves, which greatly restricts the dexterity of their fingers. The threaded connection method requires repeated rotations to complete the connection or disassembly, which is laborious and time-consuming, and is not convenient for quick installation and separation, increasing the astronauts' workload and operational risks.

[0005] To address these issues, the present invention proposes an aviation electrical connector assembly. Summary of the Invention

The sliding pin is slidably connected in the drive groove.

[0010] Preferred options also include:

[0011] An annular retainer is slidably connected to the female connector, and an annular groove is formed inside the annular retainer.

[0012] When the temperature rises, the drive assembly drives the annular retainer to move in the opposite direction, pushing the male connector away from the female connector through the arc-shaped retaining block; when the temperature drops, the drive assembly drives the annular retainer to move in the forward direction, pulling the male connector closer to the female connector through the arc-shaped retaining block.

[0013] Preferably, the driving component includes:

[0014] Several heat-conducting barrels are fixedly connected in a ring array inside the female connector. The heat-conducting barrels are filled with inert gas. A second piston is slidably connected inside the heat-conducting barrel. A first rack is fixedly connected to the end of the second piston.

[0015] Several second racks are slidably connected to the female connector in an annular array, and a third spring is fixedly connected between the second racks and the annular retainer.

[0016] A transmission gear set, wherein the transmission gear set meshes with a first rack and a second rack respectively.

[0017] Preferably, the transmission gear set includes a bracket, which is fixedly connected to the female connector. A first gear is rotatably connected to the bracket, and the first gear meshes with the bottom surface of a first rack. A second gear is fixedly connected to the shaft of the first gear, and the second gear meshes with a second rack. The radius of the first gear is larger than the radius of the second gear.

[0018] Preferred options also include:

[0019] Several connecting shells are fixedly connected in a ring array inside the female connector. A push plate is slidably connected inside each connecting shell, and a fourth spring is fixedly connected between the push plate and the connecting shell.

[0020] A limiting component is used to limit the push plate. When the joint temperature exceeds a threshold, the limiting component releases the limit on the push plate.

[0021] Preferably, the limiting component includes:

[0022] A slot is formed on the side wall of a push plate, and the side wall of the push plate is provided with a first push slope.

[0023] A snap-fit ​​block is slidably connected to the outer wall of the connecting shell. A fifth spring is fixedly connected between the snap-fit ​​block and the connecting shell. The snap-fit ​​block is snapped into a slot. The snap-fit ​​block has a second pushing slope that matches the first pushing slope.

[0024] Preferred options also include:

[0025] The L-shaped push seat is fixedly connected to the end of the snap-fit ​​block, and a drive inclined seat is fixedly connected to the side wall of the L-shaped push seat;

[0026] An L-shaped connecting frame is fixedly connected at one end to a first rack, and a push roller is fixedly connected at the other end of the L-shaped connecting frame corresponding to the position of the drive slant seat.

[0027] Preferably, a first washer is fixedly connected to the end of the male connector, and a second washer is fixedly connected to the end of the female connector.

[0029] Preferably, the inner sidewall of the female connector is provided with a ring array of limiting grooves, and the ring seat is slidably connected to the limiting grooves.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] I. This invention, by setting up an arc-shaped locking block, a first spring, and an annular groove, allows for easy connection. Simply press the button to retract the arc-shaped locking block, insert it into place, and release the button to lock the block into the groove. To separate, press the button again to retract the locking block out of the groove. The entire operation is simple and effortless, saving time and energy.

[0032] II. This invention, by setting up a heat-conducting barrel, an inert gas, a second piston, an annular retainer, and a driving assembly, allows the second piston to move due to the thermal expansion and contraction of the inert gas inside the heat-conducting barrel when the ambient temperature changes. This movement is driven by the rack and pinion gear transmission, which in turn drives the annular retainer to move axially. This movement is then pushed by the locked arc-shaped retaining block to make the male connector move slightly. At high temperatures, the reverse movement reduces the contact force and prevents expansion and compression damage; at low temperatures, the forward movement increases the contact force, eliminates the contraction gap, and prevents loosening and detachment.

[0033] III. This invention, through the setting of a connecting shell, a push plate, a fourth spring, and a limiting component, ensures that within the normal temperature range, the push plate is locked by the limiting component, and the fourth spring stores energy and is ready to be used. When the temperature exceeds a preset safety threshold, the push roller on the L-shaped connecting frame, which is linked to the first rack, touches the drive inclined seat on the L-shaped push base. Through the action of the inclined surface, it overcomes the force of the fifth spring and drives the locking block to exit the slot, releasing the limiting of the push plate. At the moment when the operator presses the button to unlock, the potential energy of the fourth spring is released instantly, and the push plate quickly pushes the mounting base to pop out the male connector, realizing the rapid separation of the male and female connectors.

Detailed Implementation

[0044] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0045] like Figures 1 to 9 An aviation electrical connector assembly shown includes:

[0046] Male connector 1 and female connector 12. The end of the male connector 1 is fixedly connected to the mounting base 2. The bottom of the mounting base 2 is connected to several arc-shaped locking blocks 3 in a ring array for sealing and sliding connection. A first spring 4 is fixedly connected between the arc-shaped locking blocks 3 and the mounting base 2. The inner wall of the female connector 12 is provided with an annular groove 1301 corresponding to the position of the arc-shaped locking blocks 3.

[0047] Air groove 102 is formed in male connector 1. Air groove 102 is in airflow communication with mounting base 2. An annular sliding seat 5 is slidably connected in air groove 102. A first piston 6 is fixedly connected to the end of the annular sliding seat 5. The first piston 6 is slidably and sealingly connected in air groove 102.

[0048] Two drive plates 7 are symmetrically fixedly connected to the side wall of the annular sliding seat 5, and the side wall of the drive plate 7 is provided with a drive groove 701.

[0049] Two buttons 8 are slidably connected to the outer wall of the male connector 1 at the position corresponding to the drive plate 7. A second spring 9 is fixedly connected between the button 8 and the side wall of the male connector 1. A linkage frame 10 is fixedly connected to the bottom of the button 8. A sliding pin 11 is fixedly connected to the bottom of the linkage frame 10. The sliding pin 11 is slidably connected in the drive inclined groove 701.

[0050] In existing technologies, during extravehicular activities, astronauts must wear heavy extravehicular activity suit gloves, which greatly restricts finger dexterity. Threaded connections require repeated rotations to complete connection or disassembly, which is laborious and time-consuming, hindering rapid installation and separation, and increasing the astronauts' workload and operational risks. This technical solution can solve the above problems, and the specific operation is as follows:

[0051] When making the connection, the operator holds the male connector 1 and inserts it into the female connector 12. While holding the male connector 1, the operator needs to press the button 8, which compresses the second spring 9 and moves it inward. At the same time, the linkage bracket 10 fixedly connected to the bottom of the button 8 moves down accordingly.

[0052] During the downward movement of the linkage frame 10, the sliding pin 11 at the bottom of the linkage frame 10 slides in the drive groove 701 on the side wall of the drive plate 7. Since the drive groove 701 is inclined, the vertical movement of the sliding pin 11 is converted into the horizontal movement of the drive plate 7, which drives the annular sliding seat 5 and its first piston 6 to slide in the air groove 102, thereby reducing the air pressure in the air groove 102. Since the air groove 102 is connected to the airflow inside the mounting seat 2, under the action of gas pressure, the arc-shaped locking block 3 overcomes the elastic force of the first spring 4 and retracts inward.

[0053] When the male connector 1 is inserted into place, the arc-shaped locking block 3 is precisely aligned with the annular groove 1301 opened on the inner wall of the female connector 12. Then, the operator releases the button 8, and under the action of the first spring 4 and the second spring 9, the button 8 is reset, and the arc-shaped locking block 3 extends outward and is inserted into the groove, thereby achieving mechanical locking between the male connector 1 and the female connector 12.

[0054] Similarly, when disassembly is required, press button 8. Under the same principle, the arc-shaped locking block 3 overcomes the elastic force of the first spring 4 and retracts inward, causing the arc-shaped locking block 3 to exit the annular groove 1301 of the female connector 12. The male connector 1 and the female connector 12 are unlocked and easily separated.

[0055] Therefore, the present invention only requires pressing button 8 to complete the connection and disassembly, which is simple and helps to save time and energy.

[0056] As a further embodiment of the present invention, it also includes an annular retainer 13, which is slidably connected to the female connector 12, and an annular groove 1301 is formed in the annular retainer 13.

[0057] When the temperature rises, the drive assembly drives the annular retainer 13 to move in the opposite direction, pushing the male connector 1 away from the female connector 12 through the arc-shaped retaining block 3; when the temperature drops, the drive assembly drives the annular retainer 13 to move in the forward direction, pulling the male connector 1 closer to the female connector 12 through the arc-shaped retaining block 3.

[0058] The drive assembly includes several heat-conducting barrels 14, which are fixedly connected in a ring array within the female connector 12. The heat-conducting barrels 14 are filled with inert gas, and a second piston 15 is slidably connected within the heat-conducting barrels 14. A first rack 16 is fixedly connected to the end of the second piston 15.

[0059] Several second racks 17 are arranged in a ring array and slidably connected to the female connector 12. A third spring 18 is fixedly connected between the second racks 17 and the ring-shaped card seat 13.

[0060] The transmission gear set meshes with the first rack 16 and the second rack 17 respectively;

[0061] The transmission gear set includes a bracket 19, which is fixedly connected inside the female connector 12. A first gear 20 is rotatably connected to the bracket 19 and meshes with the bottom surface of a first rack 16. A second gear 21 is fixedly connected to the shaft of the first gear 20 and meshes with a second rack 17. The radius of the first gear 20 is larger than the radius of the second gear 21.

[0062] Specifically, during the use of connectors in space, they often experience extreme environments, such as extreme cold and high temperatures. Connectors are prone to thermal expansion and contraction. Thermal expansion can lead to excessive compression of the connection ends, while cold contraction can cause gaps at the connection. This technical solution can solve the above problems, and the specific operation is as follows:

[0063] For example, when the ambient temperature decreases, the temperature inside the heat-conducting barrel 14 inside the female connector 12 drops, and the inert gas filled inside the barrel contracts upon cooling, reducing its volume and causing a decrease in internal pressure. The second piston 15 slides (i.e. retracts) into the heat-conducting barrel 14, driving the first rack 16, which is fixedly connected to it, to move inward synchronously. This causes the first gear 20 and the second gear 21 to rotate synchronously. The second gear 21 drives the second rack 17 to move. When the second rack 17 moves, the third spring 18 drives the annular retainer 13 to move in the positive direction towards the inside of the female connector 12 (i.e., towards the male connector 1), which helps to eliminate gaps caused by cold contraction and ensures the sealing of the connection.

[0064] When the ambient temperature rises, the temperature inside the heat-conducting barrel 14 inside the female connector 12 rises, and the inert gas filled inside the barrel expands when heated, increasing its volume and causing the internal gas pressure to increase. According to the above working principle, the third spring 18 drives the annular retainer 13 to move away from the female connector 12, making room, which helps to avoid damage caused by excessive compression of the connection end.

[0065] This enables the connector to automatically compensate for temperature changes, meaning that when it expands due to heat, it moves back to make room and avoids damage caused by excessive compression at the ends, and when it contracts due to cold, it moves forward to eliminate gaps and ensure the sealing of the connection.

[0066] It should be noted that: since the radius of the first gear 20 is larger than that of the second gear 21, this design reduces the larger stroke of the first rack 16 to the smaller and more precise stroke of the second rack 17, which is beneficial to improving the adjustment accuracy.

[0067] As a further embodiment of the present invention, it also includes a plurality of connecting shells 22, which are fixedly connected in a ring array within the female connector 12. A push plate 23 is slidably connected within the connecting shell 22, and a fourth spring 24 is fixedly connected between the push plate 23 and the connecting shell 22.

[0068] The limiting component is used to limit the push plate 23. When the joint temperature exceeds the threshold, the limiting component releases the limit on the push plate 23.

[0069] The limiting component includes a slot 2302, which is formed on the side wall of the push plate 23, and the side wall of the push plate 23 is provided with a first push slope;

[0070] The snap-fit ​​block 25 is slidably connected to the outer wall of the connecting shell 22. A fifth spring 26 is fixedly connected between the snap-fit ​​block 25 and the connecting shell 22. The snap-fit ​​block 25 is snapped into the slot 2302. The snap-fit ​​block 25 has a second pushing slope that is adapted to the first pushing slope.

[0071] It also includes an L-shaped push seat 27, which is fixedly connected to the end of the snap block 25, and a drive inclined seat 28 is fixedly connected to the side wall of the L-shaped push seat 27.

[0072] L-shaped connecting frame 29, one end of which is fixedly connected to the first rack 16, and the other end of which is fixedly connected to the push roller 30 corresponding to the position of the drive inclined seat 28.

[0073] Specifically, when the temperature inside the connector fluctuates within the normal operating range, the first rack 16 moves back and forth within the preset stroke as the temperature changes. During this process, although the first rack 16 drives the L-shaped connecting frame 29 and the push roller 30 to move synchronously, the movement range of the push roller 30 is insufficient to contact the drive inclined seat 28 on the L-shaped push seat 27 because the temperature does not exceed the limit. At this time, the push plate 23 is firmly locked in the designated position by the locking block 25.

[0074] When the connector temperature exceeds the preset safety threshold due to external heat source, long-term overload or internal failure, the push roller 30 contacts and presses the drive inclined seat 28 on the L-shaped push seat 27. Since the drive inclined seat 28 has an inclined surface, the continued movement of the push roller 30 will generate a horizontal component force. This component force overcomes the elastic force of the fifth spring 26 and drives the L-shaped push seat 27 and the snap block 25 to slide away from the push plate 23. When the snap block 25 is completely disengaged from the snap groove 2302 of the push plate 23, the limit of the push plate 23 is released.

[0075] However, since the arc-shaped locking block 3 is still stuck in the annular groove 1301, the male connector 1 and the female connector 12 are locked, the push plate 23 is compressed in the connecting shell 22 and cannot pop out, the potential energy of the fourth spring 24 is locked, and at this time, the end of the push plate 23 just contacts the mounting base 2.

[0076] When the staff presses button 8, the arc-shaped locking block 3 retracts inward and exits the annular groove 1301. At the same time, the locking state of the male connector 1 is released. At this time, the compressed fourth spring 24 immediately releases its potential energy, pushes the plate 23 to slide outward quickly, hits the mounting base 2 and pops the male connector 1 out quickly, realizing the rapid separation of the male and female connectors 12.

[0077] It should be noted that when the temperature is within the normal range, the push plate 23 is firmly locked in the designated position by the locking block 25. Therefore, the male connector 1 does not need to overcome the elastic force of the fourth spring 24 every time it is connected, which helps to save time and energy.

[0078] As a further embodiment of the present invention, a first gasket 101 is fixedly connected to the end of the male connector 1, and a second gasket 1201 is fixedly connected to the end of the female connector 12. Specifically, when the male connector 1 is fully inserted into the female connector 12 and locked, the first gasket 101 and the second gasket 1201 are pressed together and form an annular sealing interface to improve the sealing performance.

[0079] As a further embodiment of the present invention, a buffer pad 2301 is fixedly connected to the end of the push plate 23; specifically, this reduces the damage to the male connector 1 when the push plate 23 pushes the male connector 1.

[0080] As a further embodiment of the present invention, the inner sidewall of the female connector 12 is provided with a ring array of limiting grooves 1202, and the ring seat 13 is slidably connected to the limiting grooves 1202; specifically, this ensures that the ring seat 13 moves within a limited distance, avoiding overcompensation, which could result in the connection being too loose or too tight.

[0081] The working principle of this invention is as follows: When making a connection, the operator holds the male connector 1 and inserts it into the female connector 12. When holding the male connector 1, the operator needs to press the button 8, so that the button 8 compresses the second spring 9 and moves inward. At the same time, the linkage frame 10 fixedly connected to the bottom of the button 8 moves down accordingly.

[0082] During the downward movement of the linkage frame 10, the sliding pin 11 at the bottom of the linkage frame 10 slides in the drive groove 701 on the side wall of the drive plate 7. Since the drive groove 701 is inclined, the vertical movement of the sliding pin 11 is converted into the horizontal movement of the drive plate 7, which drives the annular sliding seat 5 and its first piston 6 to slide in the air groove 102, thereby reducing the air pressure in the air groove 102. Since the air groove 102 is connected to the airflow inside the mounting seat 2, under the action of gas pressure, the arc-shaped locking block 3 overcomes the elastic force of the first spring 4 and retracts inward.

[0083] When the male connector 1 is inserted into place, the arc-shaped locking block 3 is precisely aligned with the annular groove 1301 opened on the inner wall of the female connector 12. Then, the operator releases the button 8, and under the action of the first spring 4 and the second spring 9, the button 8 is reset, and the arc-shaped locking block 3 extends outward and is inserted into the groove, thereby achieving mechanical locking between the male connector 1 and the female connector 12.

[0084] Similarly, when disassembly is required, pressing button 8 causes the arc-shaped locking block 3 to overcome the elastic force of the first spring 4 and retract inward, causing the arc-shaped locking block 3 to exit the annular groove 1301 of the female connector 12. The male connector 1 and the female connector 12 are then released from locking and easily separated.

[0085] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
