Description

Technical Field

[0001] This application relates to the field of radio frequency socket plug connector technology, and more particularly to a VPX radio frequency connector. Background Technology

[0002] The VPX standard is primarily used in defense, aerospace, industrial measurement and control, radar communication, and other fields to meet the demands of high-density, high-performance computing and operation in extreme environments. One application of VPX involves interconnecting the mainboard and rear I / O cards by mounting them on opposite sides of a backplane. However, the RF sockets (mounted on the backplane) in the standard typically only support blind mating with mainboards, not with rear I / O cards. In practical applications, the RF section can only connect to the rear I / O card via cables, requiring significant space for wiring and routing, resulting in a less compact structure. Utility Model Content

[0003] The main objective of this application is to provide a VPX RF connector that aims to solve the technical problem that existing RF sockets typically only support blind insertion on one side, and that the connection between the socket and the plug is prone to loosening.

[0004] To achieve the above objectives, this application provides a VPX radio frequency connector, comprising:

[0005] RF socket, which is used for mounting to the back panel,

[0006] RF connectors, used for mounting to boards and rear I / O cards located on both sides of the backplane.

[0007] The radio frequency socket includes a positioning plate, on both sides of the positioning plate along the thickness direction, pins are respectively provided, and the radio frequency plug has a socket for engaging with the pins.

[0008] Optionally, the outer wall of the positioning plate is provided with a slot;

[0009] The radio frequency plugs on both sides of the radio frequency socket are provided with a first latch and a second latch facing each other. The first latch and the second latch can enter into the slot and form a limiting structure with two limiting surfaces opposite to the slot.

[0010] The slot is provided with an unlocking component, which can release the limiting state of the first buckle and / or the second buckle relative to the limiting surface.

[0011] Optionally, the first and second latches are arranged along a first direction. Each of the first and second latches includes an elastic plate and a fixing plate. The first end of the elastic plate is connected to the outer wall of the RF plug, and the second end of the elastic plate protrudes from the end of the RF plug. The fixing plate is disposed at the second end and has a fixing surface and a guide surface disposed opposite to each other. The guide surface is located on the side away from the second end and is used to abut against the outer wall of the RF socket to guide the elastic plate to undergo elastic deformation so that the fixing plate can enter the slot. The fixing surface abuts against the limiting surface to form a limiting structure.

[0012] Optionally, the unlocking component includes a first unlocking member, a second unlocking member, and a push plate. The first unlocking member and the second unlocking member are arranged side by side along a first direction. The first unlocking member and the second unlocking member are movable along a second direction. The unlocking member is used to guide the fixing plate to move along a third direction so that the fixing surface disengages from the limiting surface. The push plate is arranged at one end of the first unlocking member and the second unlocking member along the second direction. The push plate is capable of simultaneously driving the first unlocking member and the second unlocking member to move.

[0013] Optionally, the unlocking member has a first wedge surface extending in a second direction, and the fixing plate has a second wedge surface for engaging with the first wedge surface, thereby guiding the fixing plate to move in a third direction through the contact between the first wedge surface and the second wedge surface.

[0014] Optionally, a reset spring extending in a second direction is provided between the unlocking member and the inner wall of the slot, and the unlocking member has a spring groove for partially accommodating the reset spring.

[0015] Optionally, a guide plate is provided on the side of the push plate away from the unlocking member, and an accommodating groove with a width adapted to the guide plate is provided on the inner wall of one side of the slot, and the guide plate can be at least partially accommodated in the accommodating groove.

[0016] Optionally, the upper end of the guide plate is provided with a slider, and the top wall of the receiving groove is provided with a sliding groove that cooperates with the slider, the sliding groove penetrating the inner wall of the slot.

[0017] Optionally, the lower end of the push plate near the unlocking member is provided with a pressure groove, and both unlocking members are provided with pressure blocks. When the push plate pushes the unlocking member to move, the pressure block is located in the pressure groove.

[0018] Optionally, the upper end of the push plate is provided with a flange, which is used to facilitate applying a pushing force to the push plate.

[0019] The beneficial effects that this application can achieve are:

[0020] This application proposes a VPX RF connector. By providing pins on both sides of a positioning plate, when the RF socket is installed on a backplane, two RF plugs are respectively installed onto the circuit boards and rear I / O cards on both sides of the backplane. The two RF plugs can directly engage with the pins on both sides of the positioning plate, enabling communication connections between the circuit boards and rear I / O cards and the backplane. Compared to existing RF sockets with pins on only one side, requiring cables for communication on the other side, this design reduces wiring and makes the structure more compact. The connection stability of the RF socket and RF plugs is increased by using latches and slots. An unlocking component allows for single-sided or simultaneous unlocking of the latches on both sides.

[0035] Example 1

[0036] Reference Figure 1-7The first embodiment of this application provides a VPX radio frequency connector, including: a radio frequency socket for mounting to a backplane 60, and a radio frequency plug 20 for mounting to a board 50 and a rear I / O card 70 located on both sides of the backplane 60. The radio frequency socket includes a positioning plate 10, and pins 11 are respectively provided on both sides of the positioning plate 10 along the thickness direction. The radio frequency plug 20 has a socket 21 for engaging with the pins 11.

[0037] In this embodiment, Figure 7 This diagram is for illustrative purposes only, showing the relative positions of board 50, backplane 60, and rear I / O card 70. Board 50, also known as a printed circuit board (PCB), is a key component in computer and industrial control systems used for expanding functionality. It connects to the computer motherboard or other devices via slots, enabling hardware expansion and upgrades. Backplane 60 is a circuit board used to connect multiple boards 50 or modules, providing electrical connections and signal transmission channels between boards 50. Rear I / O card 70 is a board 50 used to expand the input / output functions of a computer or industrial control system. Four pins 11 are located on the same side of the positioning plate 10. Each pin 11 has a sleeve around its periphery. The sockets 21 on the RF connector 20 correspond one-to-one with the pins 11. When the RF connector 20 is inserted into the RF socket, the pins 11 connect with the sockets 21 to transmit electrical signals.

[0038] By setting pins 11 on both sides of the positioning plate 10, when the RF socket is installed on the back panel 60, the two RF plugs 20 are respectively installed on the board 50 and the rear I / O card 70 on both sides of the back panel 60. The two RF plugs 20 can directly cooperate with the pins 11 on both sides of the positioning plate 10 to realize the communication connection between the board and the rear I / O card 70 and the back panel 60. Compared with the existing RF socket, which only has pins 11 on one side and needs to communicate through cables on the other side, this reduces wiring and makes the structure more compact.

[0039] Example 2

[0040] As an optional implementation method, refer to Figure 1-3 In the figure, X represents the first direction, Y represents the second direction, and Z represents the third direction. This embodiment provides a connection structure between an RF socket and an RF plug 20, including: a slot 30 is provided on the outer wall of the positioning plate 10; the RF plugs 20 located on both sides of the RF socket are provided with a first latch 31 and a second latch 32 facing each other, the first latch 31 and the second latch 32 can enter into the slot 30 and form a limiting structure with two limiting surfaces opposite to the slot 30; an unlocking component 40 is provided in the slot 30, and the limiting state of the first latch 31 and / or the second latch 32 relative to the limiting surfaces can be released by the unlocking component 40.

[0041] In this embodiment, optionally, the slot 30 is disposed on the positioning plate 10, specifically on the upper end of the positioning plate 10 or on the side wall of the positioning plate 10. The first latch 31 and the second latch 32 have similar structures, and are distinguished by "first" and "second" only for ease of description. The first latch and the second latch 32 can be located simultaneously within the slot 30. Figure 1 The inner walls on both sides of the card slot 30 serve as limiting surfaces. When the first latch 31 and the second latch 32 are partially located within the card slot 30, the first latch 31 and the second latch 32 form limiting structures with the limiting surfaces. When the RF plug 20 is subjected to an external force away from the RF socket, the first latch 31 and the second latch 32 prevent the RF plug 20 from moving, thus improving the integrity of the RF socket and the RF plug 20. By setting the unlocking component 40, the unlocking component 40 can unlock only one of the first latch 31 and the second latch 32, or it can unlock both latches simultaneously, improving the convenience of unlocking and allowing for quick unlocking, making it easier to remove the RF plug 20 from the RF socket more quickly.

[0042] Example 3

[0043] As an optional implementation method, refer to Figure 1-5 This embodiment provides a specific structure of a first buckle 31 and a second buckle 32, including: the first buckle 31 and the second buckle 32 are arranged along a first direction, and both the first buckle 31 and the second buckle 32 include an elastic plate 311 and a fixing plate 312. The first end of the elastic plate 311 is connected to the outer wall of the RF plug 20, and the second end of the elastic plate 311 protrudes from the end of the RF plug 20. The fixing plate 312 is disposed at the second end, and the fixing plate 312 has a fixing surface 3122 and a guide surface 3121 disposed opposite to each other. The guide surface 3121 is located on the side away from the second end and is used to abut against the outer wall of the positioning plate 10 to guide the elastic plate 311 to undergo elastic deformation so that the fixing plate 312 can enter the slot 30. The fixing surface 3122 abuts against the limiting surface to form a limiting structure.

[0044] Specifically, such as Figure 2As shown, the left end of the first latch 31 and the right end of the second latch 32 are the first ends of the elastic plate 311, and the right end of the first latch 31 and the left end of the second latch 32 are the second ends of the elastic plate 311. During use, the RF plugs 20 located on the left and right sides of the positioning plate 10 move in the direction close to the positioning plate 10. The guide surfaces 3121 of the two latches abut against the outer wall of the positioning plate 10. During the continuous movement of the RF, the guide surfaces 3121 guide the elastic plate 311 to undergo elastic deformation. When it moves to the position of the fixed plate 312 above the slot 30, the elastic plate 311 can recover its elastic deformation, and the fixed plate 312 enters the slot 30. The fixed surface 3122 and the limiting surface are both vertical planes. The fixed surface 3122 abuts against the limiting surface, and the fixed surface 3122 and the limiting surface form a limiting structure, which prevents the fixed plate 312 from moving backward.

[0045] Optionally, the unlocking component 40 includes a first unlocking member 41, a second unlocking member 42, and a push plate 43. The first unlocking member 41 and the second unlocking member 42 are arranged side by side along a first direction. The first unlocking member 41 and the second unlocking member 42 are movable along a second direction. The unlocking member is used to guide the fixed plate 312 to move along a third direction so that the fixed surface 3122 is disengaged from the limiting surface. The push plate 43 is arranged at one end of the first unlocking member 41 and the second unlocking member 42 along the second direction. The push plate 43 can simultaneously drive the first unlocking member 41 and the second unlocking member 42 to move.

[0046] Optionally, the unlocking member has a first wedge surface 411 extending in a second direction, and the fixing plate 312 has a second wedge surface 3123 for engaging with the first wedge surface 411. The first wedge surface 411 abuts against the second wedge surface 3123 to guide the fixing plate 312 to move in a third direction.

[0047] Specifically, the first unlocking element 41 and the second unlocking element 42 are independent of each other, meaning that the first unlocking element 41 and the second unlocking element 42 can be controlled independently, allowing one of the latches to be unlocked without affecting the other latch. By setting a push plate 43 at the same end of the first unlocking element 41 and the second unlocking element 42, the push plate 43 can simultaneously control the movement of the first unlocking element 41 and the second unlocking element 42, thus simultaneously unlocking both latches. This allows users to quickly unlock according to their actual needs, improving unlocking efficiency. It should be noted that the structures of the first unlocking element 41 and the second unlocking element 42 are similar; they are distinguished only for ease of description. For ease of understanding, the unlocking process of the first unlocking element 41 will be used as an example: [Refer to...] Figure 3-5The first unlocking member 41 moves downwards, and its first wedge surface 411 contacts the second wedge surface 3123 on the fixing plate 312. The first wedge surface 411 gradually tilts upwards away from the fixing plate 312, and the second wedge surface 3123 is parallel to the first wedge surface 411 and is located at one end of the fixing plate 312 near the first unlocking member 41. When the first wedge surface 411 abuts against the second wedge surface 3123, it guides the fixing plate 312 to move away from the bottom wall of the slot 30. At this time, the elastic member undergoes elastic deformation. When the fixing surface 3122 of the elastic member completely disengages from the limiting surface of the slot 30, the limiting state between the fixing surface 3122 and the limiting surface is released. At this time, applying an external force away from the RF socket to the RF plug 20 will complete the separation of the RF plug 20 from the RF socket.

[0048] Example 4

[0049] As an optional implementation method, refer to Figure 1 and Figure 3 This embodiment provides a support structure for an unlocking member, including: a reset spring 80 extending in a second direction is provided between the unlocking member and the inner wall of the slot 30, and the unlocking member has a spring groove 412 for partially accommodating the reset spring 80.

[0050] Specifically, by setting a return spring 80, the movement of the unlocking component is buffered, and after unlocking is completed, the component can move to its initial position under the action of the return spring 80. A spring groove 412 is provided on the unlocking component to prevent the return spring 80 from sliding relative to the unlocking component. The return spring 80 also provides elastic support for the unlocking component.

[0051] Optionally, a guide plate 431 is provided on the side of the push plate 43 away from the unlocking member, and an accommodating groove (not shown in the figure) with a width adapted to the guide plate 431 is provided on the inner wall of one side of the slot 30. The guide plate 431 can be at least partially accommodated in the accommodating groove.

[0052] Optionally, a slider 432 is provided at the upper end of the guide plate 431, and a groove is provided on the top wall of the receiving groove to cooperate with the slider 432, the groove passing through the inner wall of the slot 30.

[0053] Specifically, by setting the guide plate 431 and the receiving groove, the push plate 43 can be supported and limited, while the movement path of the push plate 43 can be limited and guided, thereby improving the integration of the push plate 43 and the positioning plate 10 and reducing the possibility of the push plate 43 detaching from the positioning plate 10 during the movement process.

[0054] Optionally, the lower end of the push plate 43 near the unlocking component is provided with a pressure groove 434, and both unlocking components are provided with pressure blocks 413. When the push plate 43 pushes the unlocking component to move, the pressure blocks 413 are located in the pressure groove 434.

[0055] Specifically, by setting up the pressure block 413 and the pressure groove 434, when the push plate 43 pushes the unlocking component to move, the push plate 43 can press on the pressure block 413, increasing the integration of the push plate 43 and the unlocking component, and improving the stability of the push plate 43 and the unlocking component during the movement process.

[0056] Optionally, the upper end of the push plate 43 is provided with a flange 433, which is used to facilitate the application of thrust to the push plate 43.

[0057] Specifically, protrusions can be provided on the two unlocking components to allow the user to apply a pushing force to the push plate 43 or the unlocking component through the flange 433 or the protrusions.

[0058] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
