Description

Technical Field

[0001] This invention relates to the field of industrial smart gateway technology, and more particularly to an aviation plug-shielded connector for smart gateways. Background Technology

[0002] A smart gateway is a hardware device capable of data acquisition, protocol conversion, edge computing, security management, and remote communication. It is typically used in environments such as factory workshops, buildings, and power stations. An aviation connector is a type of electrical connector consisting of a plug (male) and a socket (female). Circuit connection is achieved through the contact of metal contacts, and it possesses characteristics such as vibration resistance, corrosion resistance, and interference resistance. Because smart gateways are often used in environments involving high electromagnetic interference, vibration, dust, and humidity, aviation connectors are commonly used due to the specific nature of these environments.

[0003] During repeated insertion and removal, if the male and female terminals of the existing aviation connector are not aligned, the male terminal will squeeze the female terminal, causing deformation of the metal plate inside the female terminal or bending of the male terminal's prong. When either of these situations occurs, it will lead to poor contact between the male and female terminals, or even damage the aviation connector and render it unusable. Summary of the Invention

[0004] To overcome the shortcomings of the above-mentioned background technology, the present invention provides an aviation plug shielded connector for smart gateways.

[0005] The technical implementation of the present invention is as follows: an aviation plug shielded connector for a smart gateway, comprising a fixed base, a fixed shell threadedly connected to the fixed base, a rotating shell mounted on the fixed shell, a plug component provided on the fixed shell, the plug component being threadedly connected to the rotating shell, a fixed module fixedly connected inside the fixed shell, circumferentially distributed connectors fixedly connected to the fixed module, a transition member provided on the connectors, symmetrically distributed contact springs fixedly connected to the transition member, an annular frame provided inside the fixed shell, the annular frame being slidably connected to the fixed module, circumferentially distributed connecting rods fixedly connected to the annular frame, all the connecting rods sharing a pressing member for pressing all the contact springs, and a driving mechanism provided inside the fixed shell for moving the annular frame.

[0006] Furthermore, the pressing element is composed of circumferentially distributed clamping sleeves, fixing elements, and circumferentially distributed pre-supporting sleeves. The outer surfaces of the symmetrically distributed contact springs are all in press-contact with the corresponding clamping sleeves, and the inner surfaces of the symmetrically distributed contact springs are all in press-contact with the corresponding pre-supporting sleeves.

[0007] Furthermore, the inner diameter of the clamping sleeve and the inner and outer diameters of the pre-supporting sleeve are both gradually varied, and the minimum inner diameter of the clamping sleeve is greater than the maximum outer diameter of the pre-supporting sleeve.

[0008] Furthermore, the pre-supported sleeve has an inclined surface on the side near the plug.

[0009] Furthermore, the driving mechanism includes: a sliding sleeve, which is slidably and rotatably connected to the outside of the fixed shell; and a limiting post, which is fixed to the sliding sleeve. The limiting post is used to drive the annular frame to move. The fixed shell is provided with a guide groove, and the limiting post slides within the guide groove.

[0010] Furthermore, the guide groove has an inclined groove and an arc groove that are interconnected, and the fixed shell is fixedly connected with an elastic clip. The elastic clip is located at one end of the arc groove on the guide groove, and the elastic clip is used to fix the limiting post.

[0011] Furthermore, it also includes a shifting mechanism disposed within the annular frame. The shifting mechanism is used to move all the contact springs. The shifting mechanism includes a fixing ring fixedly connected to the annular frame. The fixing ring is fixedly connected to a circumferentially distributed active sleeve. A circumferentially distributed fixed sleeve is fixedly connected inside the fixing ring. The transition member is splinedly connected to a pressure-bearing member. A first spring is disposed between the pressure-bearing member and the adjacent transition member. The active sleeve is used to compress the corresponding pressure-bearing member. The fixed sleeve is used to guide the pressure-bearing member. The connector is rotatably connected to the adjacent transition member.

[0012] Furthermore, the active housing is provided with several pressing surfaces and several pressing surfaces connected end to end, the pressing surfaces and pressing surfaces being staggered. The fixed housing is provided with several guide slopes and several guide straight surfaces, the guide slopes and guide straight surfaces being staggered and connected end to end.

[0013] Furthermore, it also includes: a first retaining ring, slidably connected to the sliding sleeve, and a second spring provided between the two; a second retaining ring, fixedly connected to the rotating shell, wherein the first retaining ring is used to limit the second retaining ring.

[0014] Furthermore, each of the symmetrically distributed contact springs has an elastic clamp fixed to its opposite side.

[0015] The present invention has the following advantages: The present invention supports the contact spring with the pressing element and guides the plug rod of the plug, so that the plug rod can enter between the contact springs, while preventing the plug rod from being squeezed and deformed by the contact springs.

[0016] This invention uses the clamping sleeve of the pressing component to press the outer side of the corresponding contact spring, thereby increasing the clamping force of the contact spring on the plug and ensuring the stability of the connector mating.

[0017] This invention utilizes the interaction between the active sleeve, the fixed sleeve, and the pressure-bearing component to drive the contact spring to rotate, thereby changing the contact position between the contact spring and the corresponding insertion rod, ensuring full contact between the two.

[0018] The present invention uses the cooperation of the first retaining ring and the second retaining ring to limit the rotation shell and ensure the stability of the connection between the rotation shell and the plug. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] This embodiment discloses an aviation plug shielded connector for smart gateways, which facilitates the mating of male and female connectors.

[0036] Reference Figures 1-7As shown, the device includes a fixed base 1, a fixed shell 2 threadedly connected to the left side of the fixed base 1 (the fixed shell 2 is the female end), a rotating shell 3 mounted on the left side of the fixed shell 2, and a plug 4 disposed on the left side of the fixed shell 2. The rotating shell 3 is used to fix the plug 4. The plug 4 consists of a housing and five prongs, all of which are located inside the housing (this is the existing structure, i.e., the male end). The plug 4 connects to external wiring and is threadedly connected to the rotating shell 3. A fixed module 5 is fixedly connected inside the fixed shell 2. The fixed module 5 consists of a first fixed block 501 and a second fixed block 502. Five circumferentially distributed connectors 6 are fixedly connected to the fixed module 5. The connectors 6 connect to external wiring. The connector 6 is provided with a transition piece 7, and two symmetrically distributed contact springs 8 are fixedly connected to the transition piece 7. The contact springs 8 are made of elastic metal. When the plug on the plug 4 is inserted between two adjacent contact springs 8, the connection is completed. The connector 6, the transition piece 7 and the contact springs 8 are all made of conductive materials. The contact springs 8 are metal sheets inside the existing female end. A ring frame 9 is provided inside the fixed housing 2. The ring frame 9 is slidably connected to the fixed module 5. The ring frame 9 is fixedly connected with circumferentially distributed connecting rods 10. All the connecting rods 10 are provided with a pressing member 11. The pressing member 11 is used to press all the contact springs 8. A drive mechanism for moving the ring frame 9 is provided inside the fixed housing 2.

[0037] Reference Figure 3 , Figure 5 and Figure 7 As shown, the pressing component 11 consists of five circumferentially distributed clamping sleeves 1101, a fixing component 1102, and five circumferentially distributed pre-supporting sleeves 1103. The five circumferentially distributed clamping sleeves 1101 are fixedly connected to each other, and all clamping sleeves 1101 are fixedly connected to the fixing component 1102. The fixing component 1102 is fixedly connected to all the pre-supporting sleeves 1103. The outer surfaces of the symmetrically distributed contact springs 8 are pressed into contact with the corresponding clamping sleeves 1101. The clamping sleeves 1101 are used to press the outer surfaces of two adjacent contact springs 8, so that the two contact springs 8 are in full contact with the adjacent plugs on the plug component 4. The inner surfaces of the symmetrically distributed contact springs 8 are pressed into contact with the corresponding pre-supporting sleeves 1103. The pre-support sleeve 1103 is used to press the inner sides of two adjacent contact springs 8, thereby facilitating the insertion of adjacent plugs on the plug 4. In the initial state, the pre-support sleeve 1103 is located between two adjacent contact springs 8 and presses them. The inner diameter of the clamping sleeve 1101 and the inner and outer diameters of the pre-support sleeve 1103 are both gradually increased. The inner diameter of the clamping sleeve 1101 and the inner and outer diameters of the pre-support sleeve 1103 gradually increase from right to left, and the minimum inner diameter of the clamping sleeve 1101 is greater than the maximum outer diameter of the pre-support sleeve 1103. The pre-support sleeve 1103 has an inclined surface on the side near the plug 4, which facilitates the insertion of the plug 4 into the space between the corresponding two contact springs 8.

[0038] Reference Figures 1-3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the driving mechanism includes: a sliding sleeve 21, which is slidably and rotatably connected to the outside of the fixed shell 2. Initially, the rotating shell 3 is in contact with the sliding sleeve 21, and the sliding sleeve 21 limits the rotating shell 3, preventing the rotating shell 3 from moving to the right; two limiting posts 22, which are centrally symmetrically distributed and fixed to the inside of the sliding sleeve 21, are used to drive the ring frame 9 to move. The fixed shell 2 is provided with two centrally symmetrically distributed guide grooves 23, and the limiting posts 22 slide within the adjacent guide grooves 23; the guide grooves 23 have interconnected inclined grooves and straight arcs, with the arc groove located on the left side of the inclined groove. The fixed shell 2 is fixed with two centrally symmetrically distributed elastic clips 31, which are elastic metal sheets. The elastic clips 31 are arc-shaped, and the central angle corresponding to the arc is greater than 180°. The elastic clips 31 are located at one end of the arc groove on the guide groove 23, and the elastic clips 31 are used to fix the limiting posts 22.

[0039] The working principle of the aviation plug shielded connector in this embodiment:

[0040] When assembling this connector, first push the rotating shell 3 to the left, causing it to lose contact with the sliding sleeve shell 21, until the rotating shell 3 moves to the left side of the fixed shell 2 and can no longer move. Then align the right side of the plug 4 with the left side of the rotating shell 3, and connect the threads of the plug 4 with the threads of the rotating shell 3. Then begin to rotate the rotating shell 3 counterclockwise (towards...). Figure 1 (Based on the left view), the rotating shell 3, under the action of its threads, drives the plug 4 to move to the right.

[0041] As the plug 4 moves to the right, the plug rod on the plug 4 gradually approaches the corresponding pre-support sleeve 1103 until the plug rod on the plug 4 contacts the corresponding pre-support sleeve 1103. Then, the rotating shell 3 continues to rotate, and the plug rod on the plug 4 moves relative to the corresponding pre-support sleeve 1103. The pre-support sleeve 1103 is used to open the two corresponding contact springs 8, so as to avoid the plug rod on the plug 4 from squeezing the two corresponding contact springs 8 and causing the two contact springs 8 to deform. Furthermore, the pre-support sleeve 1103 guides the plug rod on the plug 4 to easily insert between the two corresponding contact springs 8.

[0042] During the process of the plug 4 moving to the right, when the plug 4 contacts the fixed housing 2 (e.g.) Figure 2As shown), the rotating shell 3 stops rotating, the plug 4 stops moving, and the plug rod on the plug 4 is located between the corresponding two contact springs 8. Then, the sliding sleeve 21 is pushed to the left, and the sliding sleeve 21 drives the limiting post 22 on it. The limiting post 22 slides along the adjacent guide groove 23, causing the sliding sleeve 21 to rotate counterclockwise along the fixed shell 2. Figure 1 (For example, the left view).

[0043] During the leftward movement of the limiting post 22, the limiting post 22 slides along the inclined groove of the guide groove 23. The limiting post 22 drives the ring frame 9 to move to the left. The ring frame 9 drives the pressing member 11 to move through the connecting rod 10. During this process, the pre-support sleeve 1103 moves out between the two corresponding contact springs 8. The two contact springs 8 move towards each other under the elastic action and clamp the corresponding plug rod on the plug 4. During this process, the clamping sleeve 1101 moves to the left and squeezes the two corresponding contact springs 8, so that the two contact springs 8 are close to each other, further increasing the clamping force on the corresponding plug rod on the plug 4 and ensuring the stability of the connection between the two contact springs 8 and the corresponding plug rod on the plug 4.

[0044] When the limiting post 22 moves to the left end of the inclined groove on the guide groove 23, the limiting post 22 enters the arc groove of the adjacent guide groove 23, the sliding sleeve 21 stops moving to the left and contacts the rotating shell 3. At this time, the pre-support sleeve 1103 and the clamping sleeve 1101 both stop moving, all the pre-support sleeves 1103 lose contact with the corresponding two contact springs 8, and all the clamping sleeves 1101 squeeze the corresponding two contact springs 8. Then, the sliding sleeve 21 is rotated clockwise, and the limiting post 22 slides along the arc groove of the adjacent guide groove 23.

[0045] As the limiting post 22 slides along the arc groove of the adjacent guide groove 23, when the limiting post 22 comes into contact with the adjacent elastic clip 31, the elastic clip 31 gradually opens (stores power), and then the limiting post 22 enters the elastic clip 31. Under the action of elasticity, the elastic clip 31 resets and wraps around the limiting post 22. In this way, the limiting post 22 is limited by the elastic clip 31, thereby ensuring the stability of the connection between the contact spring 8 and the corresponding insertion rod.

[0046] After the above operations are completed, the connector is ready for use and can then be powered on.

[0047] When it is necessary to disconnect this connector, first rotate the sliding sleeve 21 counterclockwise to move the limiting post 22 into the inclined groove of the adjacent guide groove 23. Then push the sliding sleeve 21 to the right to make the limiting post 22 slide along the inclined groove of the adjacent guide groove 23 and drive the ring frame 9 to move to the right. During the process, the pressing member 11 moves to the right and returns to the initial position. After the sliding sleeve 21 is reset, rotate the rotating shell 3 clockwise to move the plug 4 to the left and make its upper plug gradually lose contact with the corresponding contact spring 8 until the rotating shell 3 loses contact with the plug 4, thus completing the disconnection operation of this connector.

[0048] In the above embodiments, the connector 6 and the transition member 7 are fixedly connected. In the following embodiments, the connector 6 and the transition member 7 are rotatably connected.

[0049] Example 2

[0050] This embodiment discloses an aviation plug shielded connector for a smart gateway. Based on embodiment 1, it also has the function of adjusting the position of all contact springs 8, changing the contact position between the contact springs 8 and the adjacent plugs on the plug 4.

[0051] The positions of the male plug's inner insert and the female plug's inner socket in existing connectors are fixed. However, when in contact with the same position for a long time, oxidation or corrosion can occur under the influence of the external environment. In this case, the connector will not be able to disconnect or mate smoothly, and may even render the connector unusable.

[0052] Reference Figure 2 and Figures 10-13As shown, it also includes a shifting mechanism, which is set inside the ring frame 9 to drive all the contact springs 8 to move. The shifting mechanism includes a fixing ring 41, which is fixed to the left side inside the ring frame 9. Five circumferentially distributed active housings 42 are fixed to the left side of the fixing ring 41. Several pressing surfaces 4201 and several pressing surfaces 4202 are arranged end to end on the left side of the active housing 42. The pressing surfaces 4201 and pressing surfaces 4202 are staggered. The connector 6 passes through the active housing 42. Five circumferentially distributed fixed housings 43 are fixed inside the fixed housing 2. Several guide slopes 4301 and several guide straight surfaces 4302 are arranged on the left side of the fixed housing 43. The guide slopes 4301 and guide straight surfaces 4302 are staggered and connected end to end. The active housing 42 is located inside the adjacent fixed housing 43. The transition piece 7 is splined connected to... The pressure-bearing component 44 consists of a ring and circumferentially distributed protrusions. A first spring is provided between the ring of the pressure-bearing component 44 and the adjacent transition component 7. The first spring is used to drive the pressure-bearing component 44 to reset. The pressing surface 4201 and pressing surface 4202 on the active housing 42 are used to press the corresponding protrusions of the pressure-bearing component 44. Initially, the pressing surface 4201 is aligned with the corresponding protrusion of the pressure-bearing component 44 (not in contact). The guide slope 4301 and guide straight surface 4302 on the fixed housing 43 are used to guide the protrusions of the pressure-bearing component 44. Initially, the protrusions of the pressure-bearing component 44 are in contact with the corresponding guide straight surface 4302 on the adjacent fixed housing 43. The connector 6 is rotatably connected to the adjacent transition component 7. The structure composed of the active housing 42, the fixed housing 43, and the pressure-bearing component 44 has the same function as the existing ballpoint pen pressing structure.

[0053] The working principle of the aviation plug shielded connector in this embodiment:

[0054] As the annular frame 9 moves to the left, it drives all the active housings 42 to move via the fixed ring 41. Taking one of the active housings 42 as an example, as the active housing 42 gradually moves to the left, when the pressing surface 4201 of the active housing 42 contacts the protrusion of the pressure member 44, the pressing surface 4201 on the active housing 42 pushes the protrusion of the pressure member 44 to move to the left. The adjacent first spring on the pressure member 44 stores force. During this process, the protrusion of the pressure member 44 slides along the guide surface 4302 on the fixed housing 43 until the protrusion of the pressure member 44 loses contact with the guide surface 4302 on the fixed housing 43. Then, the pressing surface 4201 on the active housing 42 continues to press the protrusion of the pressure member 44. Under the guidance of the pressing surface 4201, the protrusion of the pressure member 44 rotates counterclockwise (towards...). Figure 11(Based on the front view perspective), and contact the adjacent guide slope 4301 on the fixed sleeve 43. As the active sleeve 42 moves, the protrusion of the pressure member 44 slides along the adjacent guide slope 4301 on the fixed sleeve 43. During the process, the protrusion of the pressure member 44 slides along the pressing surface 4201.

[0055] During the sliding of the protrusion of the pressure member 44 along the adjacent pressing surface 4201, when the protrusion of the pressure member 44 contacts the connection between the pressing surface 4201 and the pressing surface 4202, the pressure member 44 stops rotating counterclockwise. Then the ring frame 9 continues to move to the left, and the active sleeve 42 pushes the protrusion of the pressure member 44 to continue to move to the left (the protrusion of the pressure member 44 loses contact with the adjacent guide slope 4301). The pressure member 44 compresses the adjacent first spring until the ring frame 9 stops moving, and then both the active sleeve 42 and the pressure member 44 stop moving.

[0056] During the counterclockwise rotation of the pressure-bearing component 44, the pressure-bearing component 44 drives the transition component 7 to rotate through the spline. The transition component 7 drives the two contact springs 8 on it to rotate. At this time, the contact springs 8 and the corresponding plugs on the plug component 4 are offset from each other, so as to avoid oxidation or wear caused by long-term contact with the same area.

[0057] The above operation is to initially change the contact position between the contact spring 8 and the corresponding plug on the plug 4 each time the connector is mated.

[0058] As the ring frame 9 moves to the right, the active sleeve 42 also moves to the right. During this process, the pressure-bearing member 44 moves to the right under the action of its first spring, maintaining contact between its protrusion and the active sleeve 42. As the pressure-bearing member 44 moves to the left, when its protrusion contacts the adjacent guide slope 4301 again (consistent with the position when it lost contact), the protrusion of the pressure-bearing member 44 continues to move to the left under the action of the first spring and begins to slide along the adjacent guide slope 4301. During the process, the pressure-bearing member 44 continues to rotate counterclockwise. The protrusion of the pressure-bearing member 44 loses contact with the active sleeve 42. As the pressure-bearing member 44 rotates, the two contact springs 8 continue to rotate until the protrusion of the pressure-bearing member 44 contacts the guide surface 4302 on the fixed sleeve 43. At this point, the pressure-bearing member 44 can no longer rotate, and the active sleeve 42 continues to move to the right until the ring frame 9 is reset. Then the active sleeve 42 stops moving, and the pressing surface 4201 of the active sleeve 42 is aligned with the pressure-bearing member 44 again.

[0059] The above operation is to change the contact position between the contact spring 8 and the corresponding plug on the plug 4 again when the connector is disconnected (the adjustment range this time is greater than the first adjustment range).

[0060] Example 3

[0061] This embodiment discloses an aviation plug shielded connector for a smart gateway, which, based on embodiment 1, also has the function of locking the rotating shell 3.

[0062] Reference Figures 1-3 , Figure 5 , Figure 6 and Figure 8 As shown, it also includes: a first retaining ring 51, slidably connected to the sliding sleeve 21, with a second spring between them; pressing plates are provided on both the front and rear sides of the first retaining ring 51 for easy operation; a second retaining ring 52, fixed to the rotating shell 3; inclined protrusions are provided on opposite sides of the first retaining ring 51 and the second retaining ring 52, and the inclination directions of the two protrusions are opposite; the first retaining ring 51 is used to limit the second retaining ring 52, preventing the second retaining ring 52 from rotating clockwise. Figure 1 (Based on the left view).

[0063] The working principle of the aviation plug shielded connector in this embodiment:

[0064] As the sliding sleeve 21 moves to the left, the first retaining ring 51 on the sliding sleeve 21 moves synchronously via the second spring. Simultaneously, the limiting post 22 slides along the inclined groove on the adjacent guide groove 23. When the limiting post 22 is about to slide to the left end of the inclined groove on the guide groove 23, the first retaining ring 51 contacts the second retaining ring 52, and the first retaining ring 51 cannot move. At this point, the sliding sleeve 21 continues to move, and the first retaining ring 51 compresses the second spring until the limiting post 22 moves to the right end of the inclined groove on the adjacent guide groove 23. Then, the limiting post 22 continues to slide along the arc groove on the adjacent guide groove 23. During this process... The sliding sleeve 21 drives the first retaining ring 51 to rotate clockwise synchronously. The first retaining ring 51 and the second retaining ring 52 slide relative to each other until the sliding sleeve 21 stops moving. Under the action of the second spring, the first retaining ring 51 moves to the left and fits tightly with the second retaining ring 52. At this time, the protrusion on the first retaining ring 51 and the protrusion on the second retaining ring 52 engage with each other. At the same time, under the limiting action of the protrusion on the first retaining ring 51, the second retaining ring 52 cannot rotate clockwise, that is, the rotating shell 3 cannot rotate clockwise, and the rotating shell 3 and the plug 4 cannot rotate relative to each other, thereby ensuring the stability of the connection between the rotating shell 3 and the plug 4.

[0065] When it is necessary to disconnect this connector, push the first retaining ring 51 to the right (the second spring is compressed), and the first retaining ring 51 loses contact with the second retaining ring 52. Then repeat the operation of rotating the sliding sleeve 21 counterclockwise in Embodiment 1 until the rotating shell 3 loses contact with the plug 4. After that, release the first retaining ring 51, and the first retaining ring 51 will reset under the action of the second spring on it.

[0066] Example 4

[0067] This embodiment discloses an aviation plug shielded connector for a smart gateway. Based on embodiment 1, it also has the function of increasing the connection strength between the contact spring 8 and the adjacent plug rods on the plug 4.

[0068] Reference Figure 4 and Figure 7 As shown, several elastic clamps 61 are fixed to the opposite sides of the symmetrically distributed contact springs 8. The elastic clamps 61 always have an elastic force that deforms towards the center. The elastic clamps 61 have a tendency to drive the adjacent contact springs 8 to bend and deform in opposite directions, thereby ensuring that the contact springs 8 and the adjacent plugs on the plug 4 are in full contact.

[0069] 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 the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
