Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a marine sealed electric connector with a self-tightening structure. Background Art

[0002] In the marine field, marine sealed electrical connectors are key components to ensure the normal operation of various electrical systems. With the continuous development of marine technology, the performance requirements for electrical connectors are becoming increasingly stringent.

[0003] When a ship is sailing, it is in an extremely harsh environment. On the one hand, the continuous impact of waves causes the hull to vibrate and shake strongly, which poses a huge challenge to the connection stability of the electrical connector. Traditional electrical connectors often find it difficult to maintain a stable connection between the plug and the socket in such a complex and dynamic environment, and are prone to loosening or even falling off, which in turn causes electrical failures, seriously affecting the normal navigation and safety of the ship. On the other hand, ships operate on the water for a long time, and the humidity of the surrounding environment is always high. Frequent impacts of waves and splashes of sea water are commonplace. In addition, during the operation of the ship, electrical equipment will inevitably fail and require timely emergency repairs. During the repair process, if the electrical connector is inconvenient to disassemble, it will greatly delay the repair time and affect the operating efficiency of the ship. To this end, our potato chip processing device and its production method solve the above problems. Summary of the invention

[0008] In the present technical solution, by providing an annular pressing plate, a continuous rightward pre-tightening force can be provided during use. This pre-tightening force helps the annular pressing plate to fit tightly against the internal structure of the connector, ensuring that the subsequent locking mechanism can work effectively.

[0009] In the above technical solution, further, the sealing mechanism includes a plurality of connecting columns, the right ends of the plurality of connecting columns are fixedly connected to the left ends of the plurality of racks respectively, the left ends of the plurality of connecting columns are fixedly connected to the same annular support sheet, the right end of the annular support sheet is fixedly connected to a plurality of symmetrically arranged first piston rods, a plurality of first air pressure cavities connected to the annular groove are opened in the connector housing, a plurality of the first piston rods match the first air pressure cavities, a first annular air pressure groove is opened on the inner wall of the connector housing, the first annular air pressure groove is connected to the plurality of first air pressure cavities, and the The inner wall of the first annular air pressure groove is fixedly connected with a first annular rubber, the right end of the connector housing is fixedly connected with a hollow cylinder, the right end of the hollow cylinder is provided with a plurality of symmetrically arranged second air pressure cavities, the inner wall of the hollow cylinder is provided with a second annular air pressure groove, the second annular air pressure groove is communicated with the plurality of second air pressure cavities, the inner wall of the second annular air pressure groove is fixedly connected with a second annular rubber, the inner walls of the plurality of second air pressure cavities are slidably connected with a second piston rod, the right end of the second piston rod is fixedly connected with the same annular baffle, and the right end of the hollow cylinder is fixedly connected with a fifth spring.

[0010] In this technical solution, the connecting column serves as an intermediate connecting piece to transmit the movement of the rack to the annular support plate, so that the linear movement of the rack can be converted into the corresponding movement of the annular support plate, thereby driving the subsequent sealing-related components to work.

[0012] In this technical solution, the storage groove provides a special accommodation space for parts such as spur gears, positive gears and slides.

[0015] In the above technical solution, further, the first annular film and the second annular film are both made of silicone rubber, and the inner walls of the first annular film and the second annular film are fixedly connected with threaded strips.

[0016] In this technical solution, silicone rubber itself has extremely low water absorption and can effectively prevent moisture penetration. When the first annular film and the second annular film are made of silicone rubber, they can form a reliable waterproof barrier between the connector housing and the internal structure to block seawater.

[0017] In the above technical solution, further, the first spring, the second spring, the third spring, the fourth spring and the fifth spring are all made of rare earth metal materials.

[0020] In this technical solution, the same size of the outer groove and the card block can ensure that the card block can be accurately matched when inserted into the outer groove. This tight fit can effectively prevent the card block from shaking or displacing under complex working conditions such as ship vibration and shaking.

[0021] The beneficial effects of the present invention are: 1. The marine sealed electrical connector with a self-tightening structure is provided with a self-locking mechanism. During the voyage of the ship, it will be constantly impacted by the waves, resulting in continuous vibration and shaking. The self-locking mechanism of the marine electrical connector can ensure a firm connection between the plug and the socket in such a complex dynamic environment. The connector with the self-locking mechanism is easy to operate and lock quickly during assembly, saving operation time.

[0022] 2. The marine sealed electrical connector with a self-tightening structure is equipped with a sealing mechanism. When the ship is sailing on the water for a long time, the surrounding humidity is high, and it is often impacted by waves and splashed with sea water. The sealing mechanism can effectively prevent seawater, rainwater and humid air from entering the interior of the electrical connector. However, the salt mist in the marine environment is highly corrosive. The sealing mechanism of the electrical connector can form a relatively closed space to prevent the salt mist from contacting the internal metal contacts and electronic components. This is crucial to protecting the electrical and mechanical properties of the electrical connector, extending its service life, and reducing failures and maintenance costs caused by corrosion.

[0023] 3. The marine sealed electrical connector with a self-tightening structure is provided with a quick-release mechanism. When electrical equipment fails and needs emergency repair during the operation of the ship, the quick-release mechanism can enable maintenance personnel to quickly separate the electrical connector, thereby quickly locating and replacing the faulty parts. Marine electrical equipment requires regular maintenance and inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1, please refer to Figure 1 - Fig.11 As shown, this embodiment provides a marine sealed electrical connector with a self-tightening structure, including a connector shell 1, a main line 2 is arranged at the left end of the connector shell 1, and a plurality of symmetrically arranged outer grooves 3 are opened on the surface of the main line 2, a secondary line 4 is arranged on the right side of the connector shell 1, and a plurality of symmetrically arranged inner grooves 5 are opened on the inner wall of the secondary line 4, an annular groove 6 is opened on the inner wall of the connector shell 1, a plurality of placement grooves 7 connected to the right end of the connector shell 1 are opened at the left end of the connector shell 1, and a plurality of slide grooves 8 are opened on the inner walls of the plurality of placement grooves 7, and the plurality of slide grooves 8 are all connected to the surface of the connector shell 1, a plurality of symmetrically arranged T-shaped support columns 9 are fixedly connected to the left end of the connector shell 1, a self-locking mechanism is arranged in the connector shell 1, a sealing mechanism is arranged in the annular groove 6, and a quick release mechanism is arranged in the slide groove 8.

[0032] Among them, the T-shaped support column 9 can provide additional support for the connection between the electrical connector and the external device. After the electrical connector is connected to the plug, the T-shaped support column 9 can be combined with the outer shell or bracket and other structures of the external device to share part of the tension, pressure or torque generated by the connection. In the environment of ship vibration and shaking, this support effect can reduce the force at the interface of the electrical connector and improve the stability and reliability of the connection.

[0033] It can be seen from this embodiment that the self-locking mechanism ensures that the plug and the socket of the electrical connector can be tightly and firmly connected under the complex vibration and shaking environment of the ship; the sealing mechanism prevents external harmful substances such as seawater, salt spray, dust, etc. from entering the connector to avoid electrical failures caused by these factors; the quick-release mechanism can quickly and safely separate the connection when necessary, which is convenient for maintenance and replacement. The three work together to enhance the overall reliability of the electrical connector in terms of connection stability, protection and maintainability, thereby ensuring the stable operation of the ship's electrical system.

[0034] Embodiment 2. This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to the technical solutions of the above embodiments, it also has the following technical features: the self-locking mechanism includes a first spring 10, the first spring 10 is fixedly connected to the left end of the connector housing 1, the other end of the first spring 10 is fixedly connected to an annular pressing plate 11, the left end of the annular pressing plate 11 is fixedly connected to a plurality of symmetrically arranged racks 12, the inner wall of the connector housing 1 is provided with a plurality of symmetrically arranged gear grooves 13, the plurality of gear grooves 13 are connected to the annular groove 6, the inner wall of the connector housing 1 is provided with a plurality of symmetrically arranged limit grooves 14, the plurality of limit grooves 14 are respectively connected to the gear grooves 13 and the annular groove 6, and the plurality of limit grooves 14 are respectively connected to the gear grooves 13 and the annular groove 6. A pinion 15 is rotatably connected to the inner wall of the gear groove 13, a hollow square block 16 is slidably connected to the inner walls of the plurality of limit grooves 14, a limit column 17 is arranged on the upper surface of the plurality of hollow square blocks 16, the lower end of the limit column 17 passes through the upper surface of the hollow square block 16 and extends to the inside, a second spring 18 is arranged in the plurality of hollow square blocks 16, the inner ends of the plurality of limit columns 17 are fixedly connected to a clamping block 19, a plurality of symmetrically arranged L-shaped clamping grooves 20 are opened at the right end of the annular pressing plate 11, a third spring 21 is fixedly connected to the inner walls of the plurality of L-shaped clamping grooves 20, an L-shaped support rod 22 is fixedly connected to the upper end of the third spring 21, and a plurality of symmetrically arranged fourth springs 23 are fixedly connected to the inner walls of the plurality of placement grooves 7.

[0035] Among them, the shape and size design of the rack can ensure the meshing accuracy with the pinion, so that the motion transmission is accurate, which is crucial to ensure the reliability of the entire self-locking mechanism. It can accurately control the position of components such as limit columns and blocks, thereby achieving stable locking.

[0036] It can be seen from the present embodiment that when the plug is inserted into the connector housing 1, the plug will push the annular pressing plate 11 to move to the right, and then the annular pressing plate 11 compresses the first spring 10 and drives the rack 12 to move to the right, and then the rightward movement of the rack 12 drives the pinion 15 meshing therewith to rotate, and the rotation of the pinion 15 drives the hollow square block 16 meshing therewith to slide downward in the limiting groove 14, and when the hollow square block 16 moves downward, the second spring 18 is compressed, and at the same time drives the limiting column 17 and the block 19 to move downward, and when the plug is fully inserted into place, under the elastic force of the second spring 18, the block 19 is snapped into the outer groove 3 to achieve preliminary locking, and when the annular pressing plate 11 moves to the right, it drives the L-shaped support rod 22 to move to the right, and then when the secondary line 4 is inserted and hits the right end of the L-shaped support rod 22, the secondary line 4 will press multiple L-shaped support rods 22 downward, and then the right end of the L-shaped support rod 22 is snapped into the inner groove 5 to achieve final locking.

[0037] Embodiment 3, this embodiment provides a marine sealed electrical connector with a self-tightening structure, in addition to the technical solutions of the above embodiments, it also has the following technical features, the sealing mechanism includes a plurality of connecting columns 24, the right ends of the plurality of connecting columns 24 are fixedly connected to the left ends of the plurality of racks 12, the left ends of the plurality of connecting columns 24 are fixedly connected to the same annular support sheet 25, the right end of the annular support sheet 25 is fixedly connected to a plurality of symmetrically arranged first piston rods 26, a plurality of first air pressure cavities 27 connected to the annular groove 6 are provided in the connector housing 1, the plurality of first piston rods 26 match the first air pressure cavities 27, the inner wall of the connector housing 1 is provided with a first annular air pressure groove 28, the first annular air pressure groove 28 is connected with multiple first air pressure cavities 27, the inner wall of the first annular air pressure groove 28 is fixedly connected with a first annular rubber 29, the right end of the connector housing 1 is fixedly connected with a hollow cylinder 30, the right end of the hollow cylinder 30 is provided with multiple symmetrically arranged second air pressure cavities 31, the inner wall of the hollow cylinder 30 is provided with a second annular air pressure groove 32, the second annular air pressure groove 32 is connected with multiple second air pressure cavities 31, the inner wall of the second annular air pressure groove 32 is fixedly connected with a second annular rubber 33, the inner walls of the multiple second air pressure cavities 31 are slidably connected with second piston rods 34, the right end of the second piston rod 34 is fixedly connected with the same annular baffle 35, and the right end of the hollow cylinder 30 is fixedly connected with a fifth spring 36.

[0038] Among them, the annular support plate can concentrate the force from the connecting column and reasonably distribute it to each first piston rod. At the same time, it also provides stable support and positioning for the first piston rod, ensuring that the first piston rod always maintains the correct direction and position during movement.

[0039] It can be seen from the present embodiment that the movement of the rack 12 will drive the connecting column 24 fixed thereto to move synchronously. Since the left ends of the plurality of connecting columns 24 are commonly fixedly connected to the annular support sheet 25, the annular support sheet 25 will also move with the connecting column 24. When the annular support sheet 25 moves to the right, the plurality of first piston rods 26 fixed at the right end thereof will slide in the first air pressure cavity 27 in the connector housing 1 accordingly. As the first piston rod 26 moves in the first air pressure cavity 27, the gas pressure in the first air pressure cavity 27 will change. Moreover, since the first annular air pressure groove 28 is connected to the plurality of first air pressure cavities 27, the gas pressure will be transmitted and balanced in this connected space, so that the first annular rubber 29 in the first annular air pressure groove 28 is affected. Due to the effect of gas pressure, it fits tightly on the surface of the plug, plays a preliminary sealing role, and prevents liquid from penetrating from this area. At the same time, the hollow cylinder 30 fixedly connected to the right end of the connector housing 1 also participates in the sealing process. When the right plug is inserted, the plug will squeeze the annular baffle 35 to move to the left. During the movement, the fifth spring 36 is squeezed and tightened. At this time, the second piston rod 34 will also be squeezed at the same time. During the squeezing, the second piston rod 34 pushes the air in the second air pressure cavity 31 to generate pressure. After that, the second annular film 33 is affected by the gas pressure, so that it fits tightly on the surface of the plug to complete the final sealing, preventing the intrusion of foreign substances and the leakage of internal substances, and ensuring the normal operation of the device and the stability of the internal environment.

[0040] Embodiment 4. This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to the technical solutions of the above embodiments, it also has the following technical features: the quick-release mechanism includes a plurality of storage grooves 37, and the storage grooves 37 are opened on the surface of the connector housing 1. The inner walls of the plurality of storage grooves 37 are rotatably connected with spur gears 38, and the inner walls of the storage grooves 37 are rotatably connected with spur gears 39, and the spur gears 39 are meshingly connected with the spur gears 38. The inner walls of the storage grooves 37 are slidably connected with slide bars 40, and the spur gears 39 are meshingly connected with the side walls of the slide bars 40. A swivel 41 is sleeved on the surface of the connector housing 1, and a plurality of tooth grooves 42 are opened on the inner wall of the swivel 41, and the plurality of tooth grooves 42 are meshingly connected with the spur gears 38.

[0041] Among them, the spur gear 38, as a key transmission component in the quick release mechanism, can convert the rotational motion of the swivel 41 into the rotational motion of the spur gear 39. By meshing with the spur gear, it realizes the transmission of force and the change of movement direction, providing power for the subsequent movement of the slide bar. This transmission method is simple and efficient.

[0042] It can be seen from the present embodiment that when disassembly operation is required, external force is applied to the swivel 41 to rotate it. During the rotation of the swivel 41, the tooth groove 42 on its inner wall will mesh with the spur gear 38 in the storage groove 37, thereby driving the spur gear 38 to rotate. Since the spur gear 38 is meshed and connected with the spur gear 39, the rotation of the spur gear 38 will be transmitted to the spur gear 39, causing the spur gear 39 to rotate accordingly. When the spur gear 39 rotates, the meshing relationship between it and the side wall of the slide bar 40 will cause the slide bar 40 to slide on the inner wall of the storage groove 37. The sliding direction and displacement of the slide bar 40 depend on the rotation direction and angle of the spur gear 39. Through the synchronous action of multiple slide bars 40, the L-shaped support rod 22 is squeezed downward, and then the L-shaped support rod 22 will be disengaged from the plug on the right. At this time, the device on the left will be reset, so as to realize convenient disassembly and installation operations and improve the maintenance and assembly efficiency of the equipment.

[0043] The present embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to the technical solutions of the above-mentioned embodiments, the present invention also has the following technical features: the pinion 15 is meshingly connected with the left side wall of the hollow square block 16, the inner wall of the hollow square block 16 is fixedly connected with the upper end of the second spring 18, the lower end of the second spring 18 is fixedly connected with the upper surface of the clamping block 19, and the second spring 18 is sleeved on the surface of the limit column 17.

[0044] The movement of the hollow square block 16 can directly affect the expansion and contraction state of the second spring, and then transmit the force to other components such as the card block through the second spring.

[0045] It can be seen from the present embodiment that when an external force acts on the pinion 15 to rotate it, since the pinion 15 is meshedly connected with the left side wall of the hollow square block 16, the rotation of the pinion 15 will be converted into the downward movement of the hollow square block 16. When the hollow square block 16 moves downward, it will compress the second spring 18 sleeved on the surface of the limit column 17. At this time, the second spring 18 stores elastic potential energy and at the same time drives the block 19 connected thereto to move upward, so that the block 19 is out of engagement or contact with other components, thereby realizing the unlocking or separation function. When the external force acting on the pinion 15 disappears, under the action of the elastic restoring force of the second spring 18, the hollow square block 16 will move upward, driving the block 19 back to the initial position, and re-forming an engagement or contact relationship with the corresponding component to complete the locking or connection operation.

[0046] The present embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features: the first annular rubber 29 and the second annular rubber 33 are both made of silicone rubber, and the inner walls of the first annular rubber 29 and the second annular rubber 33 are fixedly connected with threaded strips.

[0047] Among them, the presence of the thread strips increases the contact area and friction between the film and the sealing surface. When the film is pressed against the sealing surface under the action of air pressure, the thread strips are like small sealing ribs, which can effectively prevent gas or liquid from flowing in the tiny channels between the film and the sealing surface.

[0048] It can be seen from this embodiment that silicone rubber is a highly elastic polymer material, and its molecular chain is composed of alternating silicon atoms and oxygen atoms. This structure makes the molecular chain have good flexibility and elasticity. When subjected to external pressure, the silicone rubber molecular chain can deform so as to fit tightly to the sealing surface. In the sealing mechanism, the first annular film 29 and the second annular film 33 use this elastic deformation to fill the tiny gap between the sealing surfaces. Under the action of air pressure, the film will be squeezed toward the sealing surface, and the silicone rubber molecular chain will adaptively fill in the gap like countless tiny springs to prevent the passage of gas or liquid.

[0049] The present embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to the technical solutions of the above embodiments, it also has the following technical features: the first spring 10, the second spring 18, the third spring 21, the fourth spring 23, and the fifth spring 36 are all made of rare earth metal materials.

[0050] Among them, rare earth metal springs can withstand large elastic deformation without permanent deformation, and are not prone to fatigue damage during repeated expansion and contraction.

[0051] It can be seen from this embodiment that after being deformed by force, the first spring 10, the second spring 18, the third spring 21, the fourth spring 23, and the fifth spring 36 can rely on the advantages of rare earth metal materials, such as good temperature stability and dimensional accuracy retention, and can accurately pull the connecting parts back to the predetermined position even under complex environmental conditions, providing a solid guarantee for the continuous and reliable operation of the device.

[0052] The present embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to the technical solutions of the above-mentioned embodiments, the present invention also has the following technical features: multiple outer grooves 4 are the same size as the block 19, multiple inner grooves 5 are the same size as the right end of the L-shaped support rod 22, the right end of the L-shaped support rod 22 passes through the placement groove 7 and extends to the right end of the connector housing 1, the upper end of the fourth spring 23 is against the bottom surface of the L-shaped support rod 22, and the shape of the right end of the L-shaped support rod 22 is a triangle.

[0053] When the clamping block 19 is tightly fitted to the outer groove 4, the stress generated by the external force can be better transmitted and dispersed on the contact surfaces of the two, reducing local stress concentration, thereby improving the stability of the connection.

[0054] It can be seen from this embodiment that the inner groove 5 and the right end of the L-shaped support rod 22 are of the same size and the right end of the L-shaped support rod 22 passes through the placement groove 7 and extends to the right end of the connector housing 1. This design provides a good guiding and limiting effect for the L-shaped support rod 22. During the operation of the device, the L-shaped support rod 22 can move stably along the inner groove 5 without deviation or shaking, ensuring the accuracy and stability of its movement. At the same time, the inner groove 5 limits the range of movement of the L-shaped support rod 22, so that it can only move within the specified path, thereby ensuring the normal operation of the entire device.

[0055] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
