A quick-locking anti-loosening electrical connector device

Abstract

This invention belongs to the field of electrical connector technology and discloses a quick-locking anti-loosening electrical connector device, including an electrical connector housing and a plug. Under the elastic compression of a first compression spring, a rotating plate moves slightly upward. During this upward movement, a locking plate engages with the inner wall of a locking hole, allowing the plug's insertion hole to quickly lock into the socket within the electrical connector housing, effectively preventing accidental detachment of the connector under vibration or external force. When the rotating plate moves slightly upward, the rotating component drives a slider in the locking assembly to move in the opposite direction within a groove. The slider drives a first connecting plate and a connecting rod to move, which in turn drives a flexible spring rod. During this movement, the flexible spring rod contacts the outer wall of the locking plate inside the locking hole. Due to the multiple slots on the outer wall of the locking plate, the flexible spring rod can engage with the outer wall of the locking plate, effectively preventing the locking plate from loosening due to insufficient friction or other reasons.

Description

Technical Field

[0001] This invention belongs to the field of electrical connector technology, specifically a fast-locking anti-loosening electrical connector device. Background Technology

[0002] Electrical connectors are devices used to establish electrical connections between circuits, typically consisting of a plug and a socket. Their function is to enable the transmission of current and signals while allowing for quick connection and disconnection between devices. Electrical connectors come in many types and have a wide range of applications, covering everything from simple household appliances to complex industrial equipment, communication systems, and automotive electronics. They can provide different functions as needed, such as waterproofing, dustproofing, vibration resistance, locking, and quick-connection.

[0003] Existing technologies for rapid mating and unmating of circular electrical connectors typically employ a locking mechanism to prevent loosening. However, during this process, environmental factors such as vibration, impact, or other external forces can cause slight displacement of the connector's contact points, leading to loosening. Especially in industrial equipment, automotive, or other high-vibration environments, the connector's plug and socket may lack sufficient locking force to resist these external forces during mating and unmating. Summary of the Invention

[0004] To address the problem of insufficient locking force mentioned in the background art, where vibration causes slight displacement of the plug and socket contact points, leading to poor contact or insufficient pressure, thus affecting the locking force of the locking mechanism, this invention provides a quick-locking, anti-loosening electrical connector device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-locking anti-loosening electrical connector device, comprising an electrical connector housing and a plug, wherein a retaining plate is fixedly connected to the top of the inner wall of the electrical connector housing, a socket is fixedly connected to one end of the inner wall of the electrical connector housing, and a fixing shell is fixedly connected to the top of the plug, and further comprising a quick-locking mechanism, wherein the quick-locking mechanism comprises a fixing rod fixedly connected to both sides of the inner wall of the fixing shell, a rotating plate is rotatably connected to the outer wall of the middle end of the fixing rod, a retaining hole is provided on the top of the rotating plate, and a locking component is provided on one side of the rotating plate to prevent the electrical connector housing and the plug from loosening when plugged in.

[0006] Preferably, the locking assembly includes a round rod that passes through one side of the rotating plate, with rotating parts rotatably connected to the outer walls of both ends of the round rod, a vertical rod fixedly connected to the bottom of the rotating parts, and a round plate fixedly connected to the bottom of the vertical rod.

[0007] Preferably, a circular shell is slidably connected to the outer wall of the circular plate, the bottom of the circular shell is fixedly connected to the bottom of the inner wall of the fixed shell, and a first compression spring is fixedly connected to the bottom of the circular plate, the bottom of the first compression spring being fixedly connected to the bottom of the inner wall of the circular shell.

[0008] Preferably, the inner wall of the fixed shell is provided with sliding grooves on both sides, a rotating rod is hinged to one side of the rotating component, a slider is hinged to the bottom end of the rotating rod, and the outer wall of the slider is slidably connected to the inner wall of the sliding groove.

[0009] Preferably, a first connecting plate is fixedly connected to one side of the slider, a connecting rod is fixedly connected to one side of the first connecting plate, and a flexible spring rod is fixedly connected to the outer wall of one end of the connecting rod, wherein one flexible spring rod is provided.

[0010] Preferably, the sidewall of the slider is provided with a protective component, the protective component including a connecting rod fixedly connected to one side of the slider, and a second connecting rod fixedly connected to one end of the connecting rod.

[0011] Preferably, a piston plate is fixedly connected to the end of the second connecting rod away from the connecting frame rod, and an annular shell is slidably connected to the outer wall of the piston plate. The inner wall of the annular shell is fixedly connected to the outer wall of one end of the plug component, and four second compression springs are fixedly connected to one side of the piston plate.

[0012] Preferably, one end of the second compression spring is fixedly connected to one side of the inner cavity of the annular shell, one side of the piston plate is connected to four elastic telescopic tubes, one end of the elastic telescopic tube is connected to an annular bladder, and one side of the outer wall of the annular bladder is fixedly connected to one side of the outer wall of the annular shell.

[0013] Preferably, an auxiliary component is provided on one side of the piston plate. The auxiliary component includes a fixed block fixedly connected to both ends of one side of the piston plate. A rotating bar is hinged to one end of the fixed block, and a sliding member is hinged to one end of the rotating bar. One side of the sliding member is slidably connected to one side of the inner cavity of the annular shell.

[0014] Preferably, an elastic support rod is slidably connected through one side of the sliding member, and a circular roller is rotatably connected to the inner wall of one end of the elastic support rod. Square holes are provided on both sides of the annular shell, and the outer wall of one end of the elastic support rod is disposed inside the square hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention, through the setting of a locking assembly, inserts the plug into the interior of the electrical connector housing. During the movement of the plug, it is squeezed by a locking plate, causing a rotating plate to rotate around a fixed rod. The rotating plate drives the round rod and the rotating component to rotate. The rotating component drives the vertical rod and the round plate to descend almost vertically along the inner wall of the round shell. At the same time, the rotating component drives the rotating rod and the slider to slide along the inner wall of the slide groove. The slider drives the first connecting plate and the connecting rod to move. The connecting rod drives the flexible spring rod to move. When the locking hole opened at the rotating plate moves to the top of the locking plate, it is elastically squeezed by the first compression spring, causing the rotating plate to move slightly upward. During the upward movement of the rotating plate, the locking plate engages with the inner wall of the locking hole, thereby quickly locking the plug into the socket in the inner wall of the electrical connector housing, effectively preventing the connector from accidentally falling off under vibration or external force. When the rotating plate moves slightly upward, the rotating component drives the slider in the locking assembly to move in the opposite direction inside the groove. The slider drives the first connecting plate and the connecting rod to move, and the connecting rod drives the flexible spring rod to move. During the movement of the flexible spring rod, it will contact the outer wall of the card plate that has entered the card hole. Due to the multiple card slots set on the outer wall of the card plate, the flexible spring rod can contact and lock with the outer wall of the card plate, effectively preventing the card plate from loosening due to insufficient friction or other reasons, thereby ensuring the reliability and stability of the connector during long-term use.

[0017] This invention, through the cooperation of locking and protective components, allows the slider to move away from the circular shell as the vertical rod lowers the circular plate. This movement of the slider drives the connecting rod and the second connecting rod, which in turn causes the piston plate to slide inside the annular shell. This allows airflow from inside the annular shell to enter the elastic telescopic tube, and then through the elastic telescopic tube into the annular bladder, causing it to expand slightly. When the plug and socket are inserted, the annular bladder contacts the inner wall of the connector shell, providing a cushioning effect for both. This helps reduce the impact force during plug insertion, preventing potential mechanical damage or destruction of internal electrical components within the connector shell and socket.

[0018] This invention, through the coordinated use of protective and auxiliary components, allows the piston plate to slide within the annular shell. The piston plate moves the fixed block, which in turn moves the rotating bar and sliding member laterally along the inner cavity of the annular shell. The sliding member moves the elastic support rod, which in turn moves the roller, enabling the roller to contact the inner wall of the electrical connector shell. The compression and support provided by the two rollers against the inner wall of the connector shell effectively prevents the plug from wobbling after insertion. This results in a more stable connection, avoiding poor contact or unstable electrical performance due to a loose plug. Furthermore, the rolling mechanism of the rollers, with their outer wall rotating against the inner wall of the connector shell as the plug is inserted, prevents excessive friction between the rollers and the interior of the shell, facilitating insertion of the plug into the socket.

[0030] 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.

[0031] like Figures 1 to 10 As shown, the present invention provides a quick-locking anti-loosening electrical connector device, including an electrical connector housing 1 and a plug 2. A retaining plate 3 is fixedly connected to the top of the inner wall of the electrical connector housing 1, a socket 6 is fixedly connected to one end of the inner wall of the electrical connector housing 1, and a fixing shell 4 is fixedly connected to the top of the plug 2. The device also includes:

[0032] The quick-locking mechanism 5 includes a fixed rod 51 fixedly connected to both sides of the inner wall of the fixed housing 4. A rotating plate 52 is rotatably connected to the outer wall of the middle end of the fixed rod 51. A locking hole 53 is provided on the top of the rotating plate 52. A locking component 54 is provided on one side of the rotating plate 52 to prevent the electrical connector housing 1 from loosening when it is plugged into the plug 2.

[0033] During the insertion of the plug 2 into the connector housing 1, the plug 2 is pressed by the retaining plate 3, causing the rotating plate 52 to rotate around the fixed rod 51. The rotating plate 52 drives the round rod 541 to rotate together with the rotating plate 542, and the rotating plate 542 in turn drives the vertical rod 543 and the round plate 545 to descend almost vertically along the inner wall of the round shell 544. At the same time, the rotating plate 542 also drives the rotating rod 548 and the slider 549 to slide along the inner wall of the groove 547. The slider 549 drives the first connecting plate 5410 and the connecting rod 5411 to move, and the connecting rod 5411 causes the flexible spring rod 5412 to be displaced. When the retaining hole 53 on the rotating plate 52 moves to the top of the retaining plate 3, it is elastically compressed by the first compression spring 546, and the rotating plate 52 moves slightly upward. During this process, the retaining plate 3 engages with the inner wall of the retaining hole 53, realizing a quick locking between the socket 6 and the plug 2.

[0034] It is worth noting that when the rotating plate 52 drives the round rod 541 and the rotating component 542 to rotate together, the rotating component 542 will drive the vertical rod 543 to descend. Due to its small size, the vertical rod 543 descends almost vertically without jamming. This will not be described in detail here.

[0035] The locking assembly 54 includes a round rod 541 that passes through one side of the rotating plate 52. Both ends of the round rod 541 are rotatably connected to rotating parts 542. The bottom of the rotating parts 542 is fixedly connected to a vertical rod 543, and the bottom of the vertical rod 543 is fixedly connected to a round plate 545.

[0036] A circular shell 544 is slidably connected to the outer wall of the circular plate 545. The bottom of the circular shell 544 is fixedly connected to the bottom of the inner wall of the fixed shell 4. A first compression spring 546 is fixedly connected to the bottom of the circular plate 545. The bottom of the first compression spring 546 is fixedly connected to the bottom of the inner wall of the circular shell 544.

[0037] The inner wall of the fixed shell 4 is provided with sliding grooves 547 on both sides. A rotating rod 548 is hinged to one side of the rotating part 542. A slider 549 is hinged to the bottom end of the rotating rod 548. The outer wall of the slider 549 is slidably connected to the inner wall of the sliding groove 547.

[0038] A first connecting plate 5410 is fixedly connected to one side of the slider 549, a connecting rod 5411 is fixedly connected to one side of the first connecting plate 5410, and a flexible spring rod 5412 is fixedly connected to the outer wall of one end of the connecting rod 5411. One flexible spring rod 5412 is provided.

[0039] Using the above scheme: When the rotating plate 52 moves slightly upward, the rotating component 542 drives the slider 549 in the locking assembly 54 to move in the opposite direction inside the groove 547. The slider 549 then drives the first connecting plate 5410 and the connecting rod 5411 to move together, and the connecting rod 5411 causes the flexible spring rod 5412 to be displaced. During the movement of the flexible spring rod 5412, it will contact one side of the outer wall of the card plate 3 inside the card hole 53. Since the outer wall of the card plate 3 is provided with multiple card slots, the flexible spring rod 5412 can smoothly contact and lock into place with the outer wall of the card plate 3, thereby effectively preventing the card plate 3 from loosening due to insufficient friction or other reasons.

[0040] like Figures 1 to 10 As shown, the side wall of the slider 549 is provided with a protective component 55. The protective component 55 includes a connecting rod 551 fixedly connected to one side of the slider 549, and a second connecting rod 552 is fixedly connected to one end of the side wall of the connecting rod 551.

[0041] A piston plate 553 is fixedly connected to one end of the second connecting rod 552 away from the connecting frame rod 551. A circular shell 554 is slidably connected to the outer wall of the piston plate 553. The inner wall of the circular shell 554 is fixedly connected to the outer wall of one end of the plug piece 2. Four second compression springs 555 are fixedly connected to one side of the piston plate 553.

[0042] One end of the second compression spring 555 is fixedly connected to one side of the inner cavity of the annular shell 554. One side of the piston plate 553 is connected to four elastic telescopic tubes 557. One end of the elastic telescopic tube 557 is connected to an annular bladder 556. One side of the outer wall of the annular bladder 556 is fixedly connected to one side of the outer wall of the annular shell 554.

[0043] When the vertical rod 543 lowers the circular plate 545, the slider 549 gradually moves away from the circular shell 544, causing the connecting rod 551 and the second connecting rod 552 to move together. The second connecting rod 552 causes the piston plate 553 to slide inside the annular shell 554, pushing the airflow inside the annular shell 554 into the elastic telescopic tube 557. The airflow enters the annular bladder 556 through the elastic telescopic tube 557, causing the annular bladder 556 to expand slightly. When the plug 2 and the socket 6 are inserted, the annular bladder 556 contacts the inner wall of the electrical connector shell 1, thereby providing a buffer for the socket 6 and the plug 2, reducing the impact force of direct contact, and ensuring a smoother insertion process.

[0044] An auxiliary component 56 is provided on one side of the piston plate 553. The auxiliary component 56 includes a fixing block 561 fixedly connected to both ends of one side of the piston plate 553. A rotating bar 562 is hinged to one end of the fixing block 561, and a sliding member 563 is hinged to one end of the rotating bar 562. One side of the sliding member 563 is slidably connected to one side of the inner cavity of the annular shell 554.

[0045] A sliding member 563 has an elastic support rod 564 that is slidably connected through one side. A roller 565 is rotatably connected to the inner wall of one end of the elastic support rod 564. Square holes 566 are opened on both sides of the annular shell 554. The outer wall of one end of the elastic support rod 564 is set inside the square hole 566.

[0046] The above scheme works as follows: When the piston plate 553 slides within the annular shell 554, the piston plate 553 moves the fixed block 561 together. The fixed block 561 further drives the rotating bar 562 and the sliding member 563 to slide laterally along the inner cavity of the annular shell 554. The sliding member 563 causes the elastic support rod 564 to shift, which in turn pushes the roller 565 to move, causing the roller 565 to contact the inner wall of the electrical connector shell 1. Through the compression and support of the two rollers 565 against the inner wall of the electrical connector shell 1, it is ensured that after the socket 6 and the plug 2 are fully inserted, the left and right wobbling of the plug 2 after insertion is effectively prevented.

[0047] Working principle and usage process of this invention:

[0048] like Figure 5 As shown in the front cross-sectional structural diagram, the plug 2 is inserted into the interior of the electrical connector housing 1. During the movement of the plug 2, it is pressed by the clamping plate 3, causing the rotating plate 52 to rotate around the fixed rod 51. The rotating plate 52 drives the round rod 541 and the rotating component 542 to rotate. The rotating component 542 drives the vertical rod 543 and the round plate 545 to descend almost vertically along the inner wall of the round shell 544. At the same time, the rotating component 542 drives the rotating rod 548 and the slider 549 to slide along the inner wall of the slide groove 547. The slider 549 carries... The first connecting plate 5410 and the connecting rod 5411 move, which in turn pushes the flexible spring rod 5412 to move. When the locking hole 53 opened at the rotating plate 52 moves to the top of the locking plate 3, it is elastically squeezed by the first compression spring 546, causing the rotating plate 52 to move slightly upward. During the upward movement of the rotating plate 52, the locking plate 3 is locked in the inner wall of the locking hole 53, so that the socket of the plug 2 is quickly locked into the socket 6 in the inner wall of the electrical connector housing 1, effectively preventing the connector from accidentally falling off under vibration or external force. When the rotating plate 52 moves slightly upward, the rotating component 542 drives the slider 549 in the locking assembly 54 to move in the opposite direction inside the groove 547. The slider 549 drives the first connecting plate 5410 and the connecting rod 5411 to move. The connecting rod 5411 drives the flexible spring rod 5412 to move. During the movement, the flexible spring rod 5412 will contact one side of the outer wall of the card plate 3 that has entered the card hole 53. Due to the multiple slots provided on the outer wall of the card plate 3, the flexible spring rod 5412 can contact and lock with the outer wall of the card plate 3. Through the combination of the flexible spring rod 5412 and the rotating plate 52, the card plate 3 is effectively prevented from loosening due to insufficient friction or other reasons, thereby ensuring the reliability and stability of the connector during long-term use.

[0049] When the vertical rod 543 lowers the circular plate 545, the slider 549 gradually moves away from the circular shell 544. During this process, the slider 549 moves the connecting rod 551 and the second connecting rod 552. The second connecting rod 552 then moves the piston plate 553 inside the annular shell 554, causing the airflow inside the annular shell 554 to enter the elastic telescopic tube 557. The airflow then enters the annular bladder 556 through the elastic telescopic tube 557, causing the annular bladder 556 to expand slightly. When the plug 2 and socket 6 are connected, as... Figure 7 As shown in the top-view cross-sectional diagram, the annular bladder 556 contacts the inner wall of the electrical connector housing 1, providing a buffer for the socket 6 and the plug 2. This helps reduce the impact force during the insertion of the plug 2, preventing potential mechanical damage or destruction of internal electrical components within the electrical connector housing 1 and socket 6.

[0050] like Figures 7-8 As shown in the top-view cross-sectional diagram, when the piston plate 553 slides inside the annular shell 554, the piston plate 553 drives the fixed block 561 to move. The fixed block 561 drives the rotating bar 562 and the sliding member 563 to slide laterally along the inner cavity of the annular shell 554. The sliding member 563 drives the elastic support rod 564 to move, and the elastic support rod 564 drives the roller 565 to move, so that the roller 565 can contact the inner wall of the electrical connector shell 1. Through the compression and support of the inner wall of the electrical connector shell 1 by the two rollers 565, the plug 2 can be effectively prevented from wobbling left and right after the socket 6 and the plug 2 are inserted. This means that the connection is more stable, avoiding poor contact or unstable electrical performance caused by the loose plug 2. Due to the rolling arrangement of the roller 565, when the plug 2 is inserted into the electrical connector housing 1, the outer wall of the roller 565 rotates on the inner wall of the electrical connector housing 1, which can prevent excessive friction between the roller 565 and the interior of the electrical connector housing 1, making it easier for the plug 2 to be inserted into the socket 6.
