Description

Technical Field

[0001] The present application relates to the technical field of electromechanical interfaces, and in particular to a mechanical and electrical integrated connection device for satellites. Background Art

[0002] The prior art (CN109494509B) has achieved the mechanical and electrical integration interconnection between the module and the mounting plate on the satellite by means of floating tolerance. However, the floating tolerance connection device must be directly installed on the module and the mounting plate to achieve the mechanical and electrical integration interconnection between the two. There are strict requirements on the positional relationship between the two modules, and the mechanical connection error of the two modules must not exceed the tolerance range of the floating tolerance connection device. Moreover, the prior art does not provide how to achieve the mechanical and electrical integration connection between the modules when the spatial positions of the modules are not together.

[0003] In the actual assembly process of the satellite, it is impossible to configure the same floating tolerance interface for each module. The cost is high and limiting the installation position of each module will cause interference between modules on different mounting boards of the satellite. In actual assembly, each module is first installed on the satellite mounting board, and the connector socket or connector plug is still led out from each module by throwing the wire. After the assembly between the satellite mounting boards is completed, the connector sockets between the modules are connected to the corresponding connector plugs and fixed with cable ties. This results in messy wiring in the satellite and low space utilization. It cannot meet the needs of low-cost, batch and rapid construction of my country's aircraft. Summary of the invention

The connectors led out by the swing wires of each module on the satellite can be installed on the mechanical and electrical integration connection device for the satellite. According to the installation relationship between each satellite mounting plate, the mechanical and electrical integration connection device is installed at the appropriate position of each satellite mounting plate. When each satellite mounting plate is assembled, the connection of the connectors on the mechanical and electrical integration connection device at the corresponding position between each satellite mounting plate is synchronously realized, thereby realizing the electrical connection of different satellite mounting plates when each satellite mounting plate is mechanically assembled, thereby realizing the electrical interconnection between each functional module on different mounting plates, and achieving the effect of mechanical and electrical integration connection of the whole satellite.

[0048] The following is combined with Figure 1-14 The present application is further described in detail with specific embodiments:

[0049] The embodiment of the present application discloses a mechanical and electrical integrated connection device for a satellite.

[0050] Reference Figure 1-2 A mechanical and electrical integrated connection device for a satellite may specifically include: a socket bracket 1 and a plug bracket 2 respectively mounted on different satellite mounting plates that are mechanically connected to each other, the socket bracket 1 being used to connect a connector socket 3, the plug bracket 2 being used to connect a connector plug 4, the plug bracket 2 being connected to a connector plug 4, the connector socket 3 and the connector plug 4 being plugged in; at least one socket connection mechanism for mounting the connector socket 3 is provided on the socket bracket 1; and at least one plug connection mechanism for mounting the connector plug 4 is provided on the plug bracket 2.

[0051] Reference Figure 1-2 , wherein the position relationship between two different adjacent satellite mounting plates can be arbitrary, such as being in the same plane at a certain angle, being perpendicular to each other, etc. In this embodiment, the two different adjacent satellite mounting plates are perpendicular to each other, namely the satellite horizontal mounting plate 7 and the satellite vertical mounting plate 8. The socket bracket 1 has a socket bracket fixing hole 11 for connecting itself to the satellite horizontal mounting plate 7, and the plug bracket 2 has a plug bracket fixing hole 21 for connecting itself to the satellite vertical mounting plate 8; the installation direction of the connector socket 3 is perpendicular to the axis 11a of the socket bracket fixing hole 11; the installation direction of the connector plug 4 is parallel to the axis 21a of the plug bracket fixing hole 21; the connector plug 4 completes the connection with the connector socket 3 along the direction perpendicular to the axis 11a of the socket bracket fixing hole 11.

[0052] Reference Figure 3-4 A socket bracket positioning groove 74 is provided on the satellite horizontal mounting plate 7, and the socket bracket 1 is installed in the socket bracket positioning groove 74; a plug bracket positioning groove 83 is provided on the satellite vertical mounting plate 8, and the plug bracket 2 is installed in the plug bracket positioning groove 83; the plug bracket positioning groove 83 is provided with a wiring groove 84 for accommodating the bent connector plug wire.

[0053] Reference Figure 5-7The socket connection mechanism includes a socket wiring hole 14 and a tolerance installation position 12 which are sequentially opened on the socket bracket 1. The socket wiring hole 14 and the tolerance installation position 12 penetrate the socket bracket 1 along the center line direction of the tolerance installation position 12. The tolerance installation position 12 is rectangular. The connector socket 3 is connected to a socket mounting platform 31, which is rectangular. The dimensions of the cross section of the socket wiring hole 14 perpendicular to its own center line are smaller than the tolerance mounting position 12, that is, the length c1 and width k1 of the socket wiring hole 14 are smaller than the length c2 and width k2 of the socket mounting platform 31. The socket bracket 1 is provided with a socket opening 15 symmetrical about the center line of the socket wiring hole 14. The width e1 of the socket opening 15 is slightly larger than the thickness e2 of the mounting platform 31 on the connector socket 3, ensuring that the connector socket 3 can start from one side of the socket wiring hole 14 of the socket bracket 1, pass through the socket opening 15 and reach the tolerance mounting position 12. The socket mounting platform 31 is installed in the tolerance mounting position 12. The outer contour of the socket mounting platform 31 and the inner contour of the tolerance mounting position 12 have a single-side gap of δ1 and δ2 in the length and width directions respectively. The δ1 and δ2 are the tolerances of the socket bracket 1 to the connector socket 3, that is, the connector socket 3 can have a free movement of δ1 and δ2 in the length and width directions in the tolerance mounting position 12 respectively. The spring 18 lifts up the connector socket 3 to keep the connector socket 3 in a floating state during the entire plugging process.

[0054] The socket bracket 1 is provided with a socket limiting step 16, and the socket limiting step 16 is located on the side of the tolerance installation position 12 away from the socket wiring hole 14. The dimensions of the cross section of the socket limiting step 16 perpendicular to its own center line are all larger than the tolerance installation position 12. The socket bracket 1 is installed with a socket limiting plate 5 at the position of the socket limiting step 16 for limiting the floating range of the connector socket 3 in the tolerance installation position 12. The socket bracket 1 is provided with two spring mounting holes 13, and the hole center spacing between the two spring mounting holes 13 is d1. A spring 18 is installed in the spring mounting hole 13. The length of the spring 18 in the natural extension state is greater than the hole depth of the spring mounting hole 13, and the spring 18 is tightly pressed against the socket mounting platform 31.

[0055] The connector socket 3 with wires thrown out from each satellite module of the satellite horizontal mounting plate can pass through the socket opening 15 to the tolerance mounting position 12 of the socket bracket 1. At this time, the tail end of the connector socket 3 passes through the socket wiring hole 14, and the connector socket 3 is installed on the mechanical and electrical integrated connection device. The problem that the connector socket 3 thrown out from each module of the satellite horizontal mounting plate cannot be installed on the socket bracket due to interference with the socket wiring hole 14 of the socket bracket 1 is solved. At the same time, the socket bracket 1 is not opened to interrupt the side wall, which does not affect the strength of the connection device of the present invention. The spring 18 can make the connector socket 3 in the socket bracket 1 in a floating state. For the sake of simplicity, the satellite modules on the satellite horizontal mounting plate are not drawn in the drawings of this embodiment, and only the connector sockets of the wires thrown out from each satellite module are drawn.

[0056] In this embodiment, a limit plate mounting threaded hole 17 is provided on the socket limit step 16, which is used to install the socket limit plate 5 to limit the floating range of the connector socket 3 in the tolerance mounting position 12. The socket limit plate 5 is provided with a limit through hole 51, and screws are passed through the limit through hole 51 and the limit plate mounting threaded hole 17 to install the socket limit plate 5 on the socket limit step 16.

[0057] Reference Figure 8-9 The plug connection mechanism includes a plug mounting position 22 and a plug wiring hole 24 which are sequentially opened on the plug bracket 2. The plug mounting position 22 and the plug wiring hole 24 penetrate the plug bracket 2 along the center line direction of the plug mounting position 22. The plug mounting position 22 is rectangular. The connector plug 4 has a plug mounting platform 41, which is clamped on the plug mounting position 22. The dimensions of the cross-section of the plug wiring hole 24 perpendicular to its own center line direction are smaller than the plug mounting position 22, that is, the length c3 and width k3 of the plug wiring hole 24 are smaller than the length c4 and width k4 of the plug mounting platform 41. The plug wiring hole 24 is provided with symmetrical plug openings 25, and the width of the plug openings 25 is not less than the thickness of the plug mounting platform 41, that is, the width e3 of the plug opening 25 is slightly larger than the thickness e4 of the plug mounting platform 41, to ensure that the connector plug 4 can reach the plug mounting position 22 after passing through the plug wiring hole 24 from the rear of the plug bracket 2.

[0058] Reference Fig.10 Two locating pin mounting holes 23 are provided on the plug mounting position 22, and the hole center spacing of the two locating pin mounting holes 23 is d2, which is equal to the hole center spacing d1 of the two spring holes 13; there is a through hole 42 on the mounting platform 41; the locating pin 6 installs the connector plug 4 on the plug bracket 2 through the through hole 42 and the locating pin mounting hole 23.

[0059] Reference Figure 11-12 The positioning pin 6 includes a positioning shaft 63, a positioning step 61, and a guide pin 62 that are coaxial and arranged in sequence. The circumferential surface of the positioning shaft 63 is provided with an external thread 64, which can be arranged on the entire circumferential surface of the positioning shaft 63 or on a partial length position of the circumference of the positioning shaft 63. The diameter of the positioning step 61 is larger than the positioning shaft 63. The positioning step 61 is pressed on the plug mounting platform 41. The guide pin 62 has a conical guide head 65, and a flat groove 66 is provided on the top of the conical guide head 65, so that when the positioning shaft 63 is rotated, a flat screwdriver can be used to insert into the flat groove 66 to rotate the positioning shaft 63. The positioning shaft pin 6 has both the functions of positioning and bolting.

[0060] The positioning pin mounting hole 23 can be a through hole or a threaded hole. When the positioning pin mounting hole 23 is a through hole, the external thread 64 is arranged on the circumference of the end of the positioning shaft 63, the positioning shaft 63 cooperates with the positioning pin mounting hole 23, and the positioning pin 6 is fixed to the plug bracket 2 through the external thread 64 and the nut. When the positioning pin mounting hole 23 is a threaded hole, the external thread 64 is arranged on the entire circumferential surface of the positioning shaft 63, and the positioning pin 6 includes a positioning step 601, a guide pin 602, and an external thread 604. The positioning step 601 is pressed on the plug mounting platform 41 of the connector plug 4; the guide pin 602 has a conical guide head 605, and the top of the conical guide head 605 has a straight slot 606; the positioning pin 6 is fixed to the plug bracket 2 through the external thread 604.

[0061] In this embodiment, a special positioning pin is used instead of a screw. The positioning pin has the dual functions of installing the connector plug and guiding the position between the connector plug and the connector socket. The connector plug can be fixed on the plug bracket, and the spring mounting hole on the socket bracket and the mounting through hole of the connector socket are used to accommodate the positioning pin, without the need to set a separate positioning pin accommodating hole. While achieving the floating tolerance guiding positioning of the connector plug and the connector socket, the size of the mechanical and electrical integrated connection device is effectively reduced.

[0062] Reference Figure 5-7 The socket stop plate 5 has a positioning guide hole 52 coaxial with the spring mounting hole 13, and a trumpet-shaped opening 53 is provided at the end of the positioning guide hole 52, which can guide the positioning pin 6. The socket mounting platform 31 is provided with a mounting through hole 32, and when the connector socket 3 and the connector plug 4 are plugged in, the mounting through hole 32 is directly opposite to the positioning pin 6, so as to accommodate the tip position of the positioning pin 6.

[0063] Similarly, the connector plug 4 with the wire thrown out from the satellite vertical mounting plate can pass through the plug opening 25 to the plug mounting position 22 of the plug bracket 2 and be installed on the mechanical and electrical integrated connection device. The problem that the connector plug 4 thrown out from each module of the satellite vertical mounting plate cannot be installed on the connection device due to interference is solved, and at the same time, the plug bracket 2 is not made into a large opening, which does not affect the strength of the connection device. For the sake of simplicity, the satellite modules on the satellite vertical mounting plate are not drawn in the drawings of this embodiment, and only the connector plugs of the wires thrown out from each satellite module are drawn.

[0064] In this embodiment, the socket bracket 1 is mounted on the satellite horizontal mounting plate 7 through the socket bracket fixing hole 11, and the plug bracket 2 is mounted on the satellite vertical mounting plate 8 through the plug bracket fixing hole 21. When each satellite module is mounted on the satellite mounting plate, the present invention can realize the mechanical connection of two mutually perpendicular satellite mounting plates, and at the same time, complete the electrical connection between the connector sockets on the socket bracket and the plug bracket and the connector plug, thereby realizing the electrical interconnection between different satellite mounting plates, thereby realizing the electrical interconnection between modules on different satellite mounting plates, and even the electrical interconnection of the entire satellite.

[0065] Reference Figure 3 and Figure 4 In this embodiment, the side of the satellite horizontal mounting plate 7 includes a mounting threaded hole 71 and a positioning hole 72, and the positioning hole 72 has a trumpet-shaped opening 73; the surface of the trumpet-shaped opening 73 is coated with a solid lubricant, such as molybdenum disulfide or Teflon; the front of the satellite vertical mounting plate 8 includes a through hole 81 and a positioning pin threaded hole 82. The errors between the through hole 81 and the mounting threaded hole 71 in the horizontal direction and the vertical direction are respectively smaller than the single-side gaps δ1 and δ2 between the outer contour of the socket mounting platform 31 and the inner contour of the tolerance mounting position 12 in the length and width directions, which ensures that even if there is no mounting plate positioning pin between the horizontal mounting plate and the vertical mounting plate, the movable range of the connector socket in the tolerance mounting position is greater than the assembly error between the satellite horizontal mounting plate and the vertical mounting plate, ensuring that the mechanical connection and electrical connection between the mounting plates do not interfere. The errors between the positioning pin threaded hole 82 and the positioning hole 72 in the horizontal direction and the vertical direction are respectively smaller than the single-side gaps δ1 and δ2 between the outer contour of the socket mounting platform 31 and the inner contour of the tolerance mounting position 12 in the length and width directions.

[0066] In this embodiment, the locating pin threaded hole 82 on the satellite vertical mounting plate 8 is provided with the mounting plate locating pin 9. The trumpet-shaped opening 73 can guide the mounting plate locating pin 9 when the satellite horizontal mounting plate and the satellite vertical mounting plate are installed. The coated solid lubricant can reduce friction.

[0067] In this embodiment, the satellite horizontal mounting plate 7 is provided with a socket bracket positioning groove 74, and the satellite vertical mounting plate 8 is provided with a plug bracket positioning groove 83; the plug bracket positioning groove 83 is provided with a routing groove 84 for the bent wire of the connector plug. The socket bracket positioning groove and the plug bracket positioning groove can realize the accurate positioning of the socket bracket and the plug bracket on the satellite horizontal mounting plate and the satellite vertical mounting plate, reduce the original assembly error of the socket bracket and the plug bracket, and ensure that the floating tolerances δ1 and δ2 on the socket bracket can accommodate the mechanical assembly error between the satellite horizontal and vertical mounting plates.

[0068] The socket bracket 1 may be provided with a plurality of tolerance mounting positions 12, on which a plurality of connector sockets 3 are mounted; the plug bracket 2 may be provided with a plurality of plug mounting positions 22, on which a plurality of connector plugs 4 are mounted. It can be realized that when the horizontal satellite mounting plate and the vertical mounting plate are mechanically assembled, the electrical connection between the plurality of satellite modules on the two mounting plates is synchronously completed.

[0069] In this embodiment, the specific working process of the satellite mechanical and electrical integrated connection device can be as follows:

[0070] ① Such as Fig.13 , Fig.14 As shown, first rotate the connector socket 3 of each satellite module wire on the satellite horizontal mounting plate 7, flexibly bend the wire, align the socket mounting platform 31 of the connector socket 3 with the socket opening 15 of the socket wiring hole 14 of the socket bracket and pass through the socket opening 15. After the connector socket 3 passes through the socket opening 15 as a whole, install the connector socket 3 on the tolerance mounting position 12 of the socket bracket 1, and install the socket limit plate 5 on the socket bracket 1. At this time, the spring 18 in the spring mounting hole 13 is in a pre-compression state, and the connector socket 3 is in a floating state. Similarly, rotate the connector plug 4 of each satellite module on the satellite vertical mounting plate 8, flexibly bend the wire, align the plug mounting platform 41 of the connector plug 4 with the plug opening 25 of the plug wiring hole 24 of the plug bracket and pass through the plug opening 25. After the connector plug 4 passes through the plug opening 25 as a whole, install the connector plug 4 on the plug mounting position 22 of the plug bracket 2.

[0071] ② Then install the socket bracket 1 in the socket bracket positioning groove 74 of the satellite horizontal mounting plate 7, install the plug bracket 2 in the plug bracket positioning groove 83 of the satellite vertical mounting plate 8, and flexibly bend the wire of the connector plug 4 and throw it out from the wiring groove 84 of the satellite vertical mounting plate 8.

[0072] ③ Align the mounting plate locating pin 9 of the satellite vertical mounting plate 8 with the locating hole 72 of the satellite horizontal mounting plate 7, so that the front of the satellite vertical mounting plate 8 gradually approaches the side of the satellite horizontal mounting plate 7. At this time, the locating pin 6 on the connector plug 4 is inserted into the locating guide hole 52 under the guidance of the trumpet-shaped opening 53 of the socket limit plate 5, which guides the plugging of the connector socket 3 and the connector plug 4, and the pin and socket contacts in the connector socket 3 and the connector plug 4 begin to plug. As the satellite vertical mounting plate 8 is further approached, the locating pin 6 is gradually inserted into the through hole 32 of the mounting connector socket 3 and the spring mounting hole 13 of the socket bracket 1. The connector plug 4 is further plugged into the connector socket 3, and the spring 18 is compressed. The vertical mounting plate 8 is mechanically connected to the horizontal mounting plate 7 through screws, through holes 81 and mounting threaded holes 71. During the plugging process, the connector socket 3 is in a floating state, and can achieve a movement within the range of δ1 and δ2 in the length and width directions, so as to achieve the tolerance of the mechanical connection error between the vertical mounting plate 8 and the horizontal mounting plate 7.

[0073] ④ The vertical mounting plate 8 is mechanically connected to the horizontal mounting plate 7, and the connector plug 4 is plugged into the connector socket 3. The integration of mechanical connection and electrical connection between the vertical mounting plate 8 and the horizontal mounting plate 7 is achieved.

[0074] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0075] The above description is only the best specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
