Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a connector with a function of preventing moisture from entering the socket. Background Art

[0002] A connector is a component used to achieve electrical connection or signal transmission in electrical equipment. It is widely used in various electrical and electronic devices, including but not limited to computers, communication devices, automobiles, and industrial control systems, etc. The main function of a connector is to provide a reliable electrical connection between different components. However, ordinary connectors are prone to short circuits in a humid environment due to water leakage, so in order to ensure the smooth transmission of current or signals, workers often use various connectors with waterproof functions.

[0003] Existing connectors with waterproof functions mainly rely on the sealing ring at the interface for waterproofing and moisture-proofing. However, the sealing ring is usually made of rubber or silica gel, and is prone to aging, deformation, or even loss of elasticity after long-term use, resulting in a decline in the sealing effect of the sealing ring. And because the sealing ring is usually set at the line interface, and the line generates heat after being powered on, the sealing ring will be affected by the heat of the line, thus accelerating aging, and resulting in a relatively short overall service life of the waterproof connector.

[0004] Based on the above situation, the present invention proposes a connector with a function of preventing moisture from entering the socket, which has a long service life and good waterproof effect. Summary of the Invention

[0005] In order to overcome the shortcomings that existing connectors with waterproof functions mainly rely on the sealing ring at the interface for waterproofing and moisture-proofing, and the rubber or silica gel sealing ring is prone to aging, deformation, or even loss of elasticity after long-term use, resulting in a decline in the sealing effect of the sealing ring, and the sealing ring is also prone to be affected by the heat of the line, thus accelerating aging, resulting in a relatively short overall service life of the waterproof connector, the present invention provides a connector with a function of preventing moisture from entering the socket, which has a long service life and good waterproof effect.

[0006] A connector with a function of preventing moisture from entering the socket includes a connecting sleeve, a connecting plug, a moving frame, a first mounting plate frame, an isolation film, a second mounting plate frame, a clamp, a rotating frame, and a screw. The connecting sleeve is inserted with the connecting plug. The connecting sleeve is fixedly connected with the first mounting plate frame.

The connecting plug is fixedly connected with the second mounting plate frame. The moving frame is in contact and cooperation with the second mounting plate frame. The second mounting plate frame is rotatably connected with rotating frames evenly distributed in a circumferential manner. The rotating frame is threadedly connected with the screw. The screw is rotatably connected with the clamp. The clamp is in contact and cooperation with the moving frame.

[0007] Preferably, a sealing ring is fixedly connected to the moving frame.

[0008] Preferably, the separator membrane is made of polyurethane.

[0009] Preferably, a sealing mechanism is further included. The sealing mechanism is arranged on the first mounting plate frame and the second mounting plate frame. The sealing mechanism includes a rotating block, a soft sleeve, a tensioning rope, a gear, a limiting frame and a torsion spring. The paired rotating blocks are respectively rotatably connected to the first mounting plate frame and the second mounting plate frame. The rotating block is rotatably connected with the limiting frames distributed equidistantly in a circumferential manner. A torsion spring is fixedly connected between the limiting frame and the rotating block. Gears are fixedly connected to both the first mounting plate frame and the second mounting plate frame. The gears are in extrusion fit with the limiting frames. Soft sleeves are fixedly connected to both the first mounting plate frame and the second mounting plate frame. The soft sleeves are wound with tensioning ropes. One end of the tensioning rope is fixedly connected to the rotating block. The other end of one side of the tensioning rope is fixedly connected to the first mounting plate frame. The other end of the tensioning rope on the other side is fixedly connected to the second mounting plate frame.

[0010] Preferably, a close-fitting mechanism is further included. The close-fitting mechanism is arranged on the first mounting plate frame. The close-fitting mechanism includes a pressing frame, a pressing ball and an elastic rope. The pressing frames distributed equidistantly in a circumferential manner are all rotatably connected to the first mounting plate frame. An elastic rope is fixedly connected between the pressing frame and the moving frame. The elastic rope is fixedly connected with pressing balls distributed evenly at equal intervals. The pressing balls are in extrusion fit with the separator membrane.

[0011] Preferably, the pressing frame is provided with an arc surface.

[0012] Preferably, a separating mechanism is further included. The separating mechanism is arranged on the rotating block.

[0014] Compared with the prior art, the present invention has the following advantages: 1. Through components such as a moving frame and a clamp, the present invention can use a separator membrane made of polyurethane to wrap and protect the socket of the connecting sleeve and the connecting plug. In this way, not only can water be effectively prevented from entering the socket, but also the rapid aging of the separator membrane caused by the heat generated by the energized circuit can be avoided, improving the waterproof effect and service life of this connector.

[0015] 2. Through components such as a rotating block and a tensioning rope, the present invention enables the soft sleeve to be closely attached to the circuit, thereby ensuring good sealing between the circuit and the connecting sleeve and the connecting plug, so as to prevent water vapor from entering the connector from the connection between the circuit and the connecting sleeve and the connecting plug, improving the waterproof effect of this connector.

[0016] 3. Through components such as the pressing frame and the pressing ball, the present invention can contact and squeeze the isolation film, so that the isolation film can be kept in close contact with the connecting sleeve and the connecting plug as much as possible. At the same time, it can also provide a certain degree of protection for the isolation film to reduce the possibility of the isolation film being cut by external objects, thereby improving the service life of this connector.

[0017] 4. Through components such as the elastic clamping frame and the elastic rope, the present invention can segment and cut off the isolation film as needed to prevent the entire isolation film from losing its waterproof effect due to damage at any point, thereby improving the waterproof effect and service life of this connector.

[0018] 5. Through components such as the fixing plate and the clamping ring, the present invention can limit the position of the circuit to prevent the circuit from being bent and causing a gap between the circuit and the soft sleeve, thereby affecting the sealing performance between the circuit and the soft sleeve, and improving the waterproof effect of this connector.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Embodiment 1 A connector having a function of preventing moisture from entering the socket, as Figures 1 - 5 shown, includes a connecting sleeve 1, a connecting plug 11, a moving frame 12, a first mounting plate frame 13, an isolation film 14, a second mounting plate frame 15, a clamping device 16, a rotating frame 17, and a screw 18. The connecting plug 11 is inserted into the left side of the connecting sleeve 1, the first mounting plate frame 13 is fixedly connected to the right side of the connecting sleeve 1, the isolation film 14 is fixedly connected to the left side of the first mounting plate frame 13, the moving frame 12 is fixedly connected to the left end of the isolation film 14, the second mounting plate frame 15 is fixedly connected to the left side of the connecting plug 11, the moving frame 12 is in contact and cooperation with the second mounting plate frame 15, the rotating frames 17 are circumferentially and equally spaced and rotatably connected to the outside of the second mounting plate frame 15, the screw 18 is threadedly connected to the right side of the rotating frame 17, and the clamping device 16 is rotatably connected to the right side of the screw 18 and is in contact and cooperation with the moving frame 12.

[0033] As Figure 3 and Figure 4 shown, a sealing ring is fixedly connected to the left side of the moving frame 12.

[0034] As Figure 3 and Figure 4 shown, the isolation film 14 is made of polyurethane material.

[0035] When a worker needs to connect two wires together, the right - hand wire can be first connected to the connecting sleeve 1, and the left - hand wire can be connected to the connecting plug 11. Then, the connecting sleeve 1 and the connecting plug 11 are inserted together to complete the connection between the two wires. After that, the equally - spaced - around - the - circumference clamps 16, the rotating frames 17, and the screw rods 18 can all be rotated away from the connecting plug 11, and the moving frame 12 is moved to the left until it contacts the second mounting plate frame 15. The isolation film 14 is then stretched and wraps part of the connecting sleeve 1 and the connecting plug 11. Then, the equally - spaced - around - the - circumference clamps 16, the rotating frames 17, and the screw rods 18 are rotated in the reverse direction to reset, and the clamp 16 hooks the right end of the moving frame 12. At this time, the screw rod 18 can be rotated forward, thereby driving the clamp 16 and the moving frame 12 to continue moving to the left, and making the moving frame 12 closely adhere to the second mounting plate frame 15. Moreover, since a sealing ring is fixedly connected to the left end of the moving frame 12, there is good sealing between the moving frame 12 and the second mounting plate frame 15. In this way, the connection sleeve 1 and the socket of the connecting plug 11 can be wrapped and protected by the isolation film 14, effectively preventing moisture from entering the socket and avoiding the rapid aging of the isolation film 14 due to the heat generated when the wire is energized, improving the waterproof effect and service life of this connector. When a worker needs to disconnect the two wires, the screw rod 18 can be rotated in the reverse direction first, thereby driving the clamp 16 to move to the right to reset, and making the equally - spaced - around - the - circumference clamps 16, the rotating frames 17, and the screw rods 18 all rotate away from the connecting plug 11. Then, the moving frame 12 is moved to the right to reset, and the connecting plug 11 is pulled out of the connecting sleeve 1.

[0036] Embodiment 2 On the basis of Embodiment 1, as Figure 6 and Figure 7 shown, there is also a sealing mechanism. The sealing mechanism is arranged on the first mounting plate frame 13 and the second mounting plate frame 15. The sealing mechanism includes rotating blocks 2, soft sleeves 21, tension ropes 22, gears 23, limiting frames 24, and torsion springs 25. The two rotating blocks 2 are respectively rotatably connected to the right side of the first mounting plate frame 13 and the left side of the second mounting plate frame 15. The rotating blocks 2 internally rotatably connect the equally - spaced - around - the - circumference limiting frames 24. A torsion spring 25 is fixedly connected between the limiting frames 24 and the rotating blocks 2. Gears 23 are fixedly connected to the outside of both the first mounting plate frame 13 and the second mounting plate frame 15. The gears 23 are in extrusion fit with the adjacent limiting frames 24. Soft sleeves 21 are fixedly connected to the inside of both the first mounting plate frame 13 and the second mounting plate frame 15. Tension ropes 22 are wound around the outside of the soft sleeves 21. One end of each tension rope 22 is fixedly connected to the adjacent rotating block 2. The other end of the right - hand tension rope 22 is fixedly connected to the first mounting plate frame 13, and the other end of the left - hand tension rope 22 is fixedly connected to the second mounting plate frame 15.

[0037] When the worker connects the right - hand line to the connecting sleeve 1 and the left - hand line to the connecting plug 11, the line needs to pass through the soft sleeve 21 on the first mounting plate frame 13 or the second mounting plate frame 15 to be connected to the connecting sleeve 1 or the connecting plug 11. Therefore, at this time, the worker can rotate the rotating block 2 clockwise, thereby driving the tensioning rope 22 to gradually tighten and wind around the soft sleeve 21. After the tensioning rope 22 is tightened, it will squeeze the soft sleeve 21 and keep the soft sleeve 21 in close contact with the line. In this way, it can ensure good sealing between the line and the connecting sleeve 1 and the connecting plug 11, so as to prevent water vapor from entering the connector at the connection between the line and the connecting sleeve 1 and the connecting plug 11, improving the waterproof effect of this connector. During this period, the circumferentially equidistributed limiting frames 24 will rotate clockwise with the rotating block 2. When the limiting frame 24 rotates clockwise, it will intermittently contact and be squeezed by the gear 23, and then the limiting frame 24 will rotate outward, and the torsion spring 25 will deform accordingly. When the limiting frame 24 rotates with the rotating block 2 to separate from the protrusion of the gear 23, the limiting frame 24 will rotate inward and reset under the action of the torsion spring 25 and closely adhere to the depression of the gear 23. When the rotating block 2 wants to drive the limiting frame 24 to rotate counterclockwise, the gear 23 will hinder the rotation of the limiting frame 24, thus preventing the rotating block 2 and the limiting frame 24 from rotating counterclockwise and causing the tensioning rope 22 to become loose, ensuring that the soft sleeve 21 always remains in close contact with the line.

[0038] As Figure 8 shown, it further includes a close - fitting mechanism. The close - fitting mechanism is arranged on the first mounting plate frame 13. The close - fitting mechanism includes a pressing frame 3, a pressing ball 31 and an elastic rope 32. The circumferentially equidistributed pressing frames 3 are all rotatably connected to the outside of the first mounting plate frame 13. An elastic rope 32 is fixedly connected between the pressing frame 3 and the moving frame 12. The middle of the elastic rope 32 is fixedly connected with evenly distributed pressing balls 31 at equal intervals, and the pressing balls 31 are in extrusion fit with the isolation film 14.

[0039] As Figure 8 shown, an arc surface is provided in the middle of the pressing frame 3.

[0040] When the worker moves the moving frame 12 to the left and makes it close to the second mounting plate frame 15, the moving frame 12 will pull the elastic rope 32 and make the elastic rope 32 gradually straighten. After the elastic rope 32 is gradually straightened, it will pull the pressing frame 3, so that the circumferentially equidistributed pressing frames 3 will all rotate towards the direction close to the isolation film 14 and squeeze the isolation film 14. And the pressing balls 31 on the straightened elastic rope 32 will also contact and squeeze the isolation film 14, so that the isolation film 14 can be kept in close contact with the connecting sleeve 1 and the connecting plug 11 as much as possible to reduce the gap. At the same time, it can also provide a certain degree of protection for the isolation film 14 by means of the elastic rope 32 and the pressing frame 3 to reduce the possibility of the isolation film 14 being scratched by external objects. When the moving frame 12 moves to the right and resets, the elastic rope 32 will immediately contract and return to its original state.

[0041] As Figure 9 andFigure 10 As shown in the figure, it further includes a separating mechanism. The separating mechanism is arranged on the rotating block 2 and includes a placing block 4, an elastic clamping frame 41, a stabilizing column 42 and an elastic cord 43. The two placing blocks 4 are respectively fixedly connected to the left side and the right side of the left and right rotating blocks 2. An elastic clamping frame 41 is slidably connected to the outside of the placing block 4. A stabilizing column 42 is fixedly connected to the top of the elastic clamping frame 41, and an elastic cord 43 is fixedly connected to the middle of the elastic clamping frame 41.

[0042] After the worker fixes the moving frame 12 with the clamp 16, the elastic clamping frames 41, the stabilizing columns 42 and the elastic cords 43 on the left and right sides can also be removed from the placing block 4, and the two elastic clamping frames 41 can be clamped at appropriate positions of the connecting sleeve 1 or the connecting plug 11 as needed. Immediately, the elastic clamping frame 41 and the elastic cord 43 contact and squeeze the isolation film 14, so that this part of the isolation film 14 is closely attached to the connecting sleeve 1 or the connecting plug 11, thereby segmenting and separating the isolation film 14, so as to prevent the entire isolation film 14 from losing its waterproof effect due to any damage to the isolation film 14, improving the waterproof effect and service life of the isolation film 14. And when the worker needs to fix the connected circuit, the stabilizing column 42 on the installed elastic clamping frame 41 can also be inserted into the soil to fix the circuit, the connecting sleeve 1 and the connecting plug 11. When not needed, the components such as the elastic clamping frame 41 can be removed from the connecting sleeve 1 and the connecting plug 11 and reinstalled on the placing block 4.

[0043] Such as Figure 1 and Figure 11 As shown in the figure, it further includes a limiting mechanism. The limiting mechanism is arranged on the placing block 4 and includes a fixing plate 5 and a clamping ring 51. The fixing plate 5 is fixedly connected to the lower side of the placing block 4, and a clamping ring 51 is fixedly connected to the side of the fixing plate 5 away from the placing block 4.

[0044] When the worker connects the right-end circuit to the connecting sleeve 1 and the left-end circuit to the connecting plug 11, the fixing plate 5 and the clamping ring 51 can guide and limit the circuit, so as to facilitate the worker to pass the circuit through the soft sleeve 21 and insert it into the connecting sleeve 1 or the connecting plug 11. At the same time, the clamping ring 51 can also prevent the circuit from being bent and causing a gap between the circuit and the soft sleeve 21, thereby affecting the sealing performance between the circuit and the soft sleeve 21.

[0045] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
