Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a waterproof connector for electromechanical equipment. Background Art

[0002] An electromechanical equipment connector is a device used to achieve internal or external electrical connections of electromechanical equipment. It acts as a bridge between mechanical equipment and electronic systems, capable of transmitting signals, power, or data to ensure the normal operation of the equipment.

[0003] Currently, the patent with the publication number CN216251357U discloses a connector for electromechanical equipment with an anti-loosening structure, including a socket and a plug. A connecting pipe is arranged inside the socket, a connecting lead is arranged inside the plug, an outer sleeve pipe is arranged on the side of the socket, and an inner inserting pipe is arranged on the side of the plug. Through the mutual cooperation among the plug, socket, connecting pipe, connecting lead, outer sleeve pipe, inner inserting pipe, air extraction pipe, piston rod, piston head, moving ring, first communication groove, second communication groove, first one-way plate, and second one-way plate, the connector for electromechanical equipment with an anti-loosening structure achieves the effect of reducing the probability of generating electric sparks during the insertion and extraction of the connector, and avoiding the ignition of flammable and explosive gases in the air due to electric sparks. It solves the problem that the electric sparks generated during the insertion and extraction of aviation plug connectors not only affect the service life of the connectors, but also may ignite dangerous gases in the air in flammable and explosive environments.

[0004] However, in the actual use process of the above connector, the following problems still exist:

[0005] Some electromechanical equipment needs to work in outdoor humid environments or wading areas. In addition, the commonly used connectors for current electromechanical equipment usually consist of a male end and a female end, which are connected only by a simple plugging method. This connection method is not only prone to loosening due to vibration or external forces, but also may make the connection point a weak point for water intrusion. Once water enters, the connector is very likely to have problems such as short circuit, corrosion, or contamination, and in severe cases, it may even cause safety hazards, affecting the normal operation and service life of the equipment.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] See also Figures 1 - 12 A waterproof connector for electromechanical equipment comprises a female terminal 1 and a male terminal 2 which match each other, wherein a No. 1 sealing component is connected to the outer wall of the female terminal 1, a water-chromic component is connected to the other end of the No. 1 sealing component, a stirring component is connected to the inside of the water-chromic component, and the other end of the stirring component passes through the outside of the water-chromic component, a No. 2 sealing component and a supporting component are connected to the outer wall of the male terminal 2, a toggle component is connected between the No. 2 sealing component and the supporting component, the inner side of the toggle component is connected to one end of the stirring component located outside the water-chromic component, and the No. 1 sealing component and the water-chromic component are both located inside the No. 2 sealing component.

[0038] like Figures 1 to 12As shown, the waterproof connector for electromechanical equipment in the present invention can be installed according to the following steps:

[0039] Step 1: First install the male terminal 2 on the electromechanical equipment, and then align the female terminal 1 with the male terminal 2 and insert it. As the female terminal 1 is continuously inserted, not only the male terminal 2 and the female terminal 1 are gradually tightened, but also the No. 1 sealing component at the front end of the female terminal 1 is gradually inserted into the No. 2 sealing component of the male terminal 2. When the connection between the male terminal 2 and the female terminal 1 is stable, the No. 1 sealing component and the No. 2 sealing component are also tightened, so that the connection between the male terminal 2 and the female terminal 1 can be sealed and covered, thereby reducing the probability of moisture entering from here.

[0040] Step 2: When the male terminal 2 and the female terminal 1 are blocked by the two sealing components, the water-chromic component will also be completely blocked at the connection between the male terminal 2 and the female terminal 1, and the water-chromic component is still located behind the two sealing components. Therefore, when the sealing effect of the two sealing components deteriorates or fails, moisture will penetrate into the interior from the connection between the two sealing components, and after entering the interior of the two sealing components, it will first contact the water-chromic component. At this time, you only need to observe whether the water-chromic component changes color to understand whether water has entered the connection between the male terminal 2 and the female terminal 1, so that you can timely repair and replace the sealing component according to the situation.

[0041] Step 3: When there is no major damage to the two sealing components and only slight water ingress occurs, only a small part of the color-changing powder inside the water-sensitive color-changing component may change color. At this time, the color change cannot be promptly and clearly seen from the outside. At this time, you can rotate the toggle component located between the support component and the No. 2 sealing component. After the toggle component is rotated, the stirring component can be rotated inside the water-sensitive color-changing component, and the powder inside the water-sensitive color-changing component can be stirred and changed position, making it convenient for external observation.

[0042] As a preferred embodiment of the present invention, the No. 1 sealing component includes an outer trumpet ring 10 and a No. 1 sealing ring 11. The inner wall of one end of the outer trumpet ring 10 is fixedly connected to the outer wall of the female end 1, the outer wall of the other end of the outer trumpet ring 10 is fixedly connected to the inner side of the No. 1 sealing ring 11, the outer side of the No. 1 sealing ring 11 is connected to the inner side of the No. 2 sealing component, and the end of the outer trumpet ring 10 close to the No. 1 sealing ring 11 is connected to the water-changing color component.

[0043] More specifically, when the male terminal 2 and the female terminal 1 need to be connected, the female terminal 1 only needs to be aligned with the male terminal 2 and inserted. While the female terminal 1 is inserted into the male terminal 2, the outer horn ring 10 and the No. 1 sealing ring 11 will be inserted into the No. 2 sealing component together, so that the connection between the male terminal 2 and the female terminal 1 can be sealed in cooperation with the No. 2 sealing component, thereby reducing the probability of water ingress.

[0044] As a preferred embodiment of the present invention, the water-changing color component includes a color-changing ring 12, a mounting ring 16 and a microporous membrane 21. A mounting port 15 is provided on the inner wall of the outer trumpet ring 10 near one end of the No. 1 sealing ring 11. The outer wall of one end of the mounting ring 16 is threadedly connected to the inner wall of the mounting port 15. The outer wall of the other end of the mounting ring 16 is fixedly connected to one side of the color-changing ring 12. A powder collecting chamber 23 is provided on the side of the color-changing ring 12 near the mounting ring 16. The inner wall of the powder collecting chamber 23 near one end of the mounting ring 16 is fixedly connected to the microporous membrane 21. The stirring component is located in the powder collecting chamber 23.

[0045] More specifically, when the female end 1 is not inserted into the male end 2, the mounting ring 16 is aligned with the mounting opening 15 and screwed into the mounting opening 15 by means of threads, so that the water-changing color component can be connected between the No. 1 sealing component and the female end 1. The connection by means of threads can also make it easier to disassemble during later maintenance and replacement.

[0046] In addition, when the water-sensitive color-changing component follows the female terminal 1 and is inserted into the No. 2 sealing component, the microporous membrane 21 will face the direction of the No. 1 sealing ring 11. When water enters between the No. 1 sealing ring 11 and the No. 2 sealing component, the water will pass through the microporous membrane 21 and come into contact with the color-changing powder in the powder collecting chamber 23 of the color-changing ring 12. The color-changing powder will change color after contacting water. The maintenance personnel can observe the color change of the internal powder through the transparent shell of the color-changing ring 12, thereby separating the male terminal 2 and the female terminal 1 in time, and inspecting and replacing the two sealing components.

[0047] It should be noted here that color-changing powder is an existing mature technology, so it will not be described in detail here.

[0048] As a preferred embodiment of the present invention, the stirring assembly includes a partition ring 19, an inner gear ring 17, two No. 1 rotating rings 22, a plurality of stirring rods 20 and a plurality of transmission assemblies. A No. 1 rotating port 24 is provided on both sides of the inner wall of the powder collecting chamber 23. The outer walls of the two No. 1 rotating rings 22 are rotatably connected to the inner walls of the two No. 1 rotating ports 24 respectively. The adjacent sides of the two No. 1 rotating rings 22 are fixedly connected to the two sides of the partition ring 19 respectively. The partition ring 19 separates the powder collecting chamber 23 into two areas. The side of the partition ring 19 away from the microporous membrane 21 is fixedly connected to the side wall of the inner gear ring 17. The inner gear ring 17 is connected to one end of the plurality of transmission assemblies. The other ends of the plurality of transmission assemblies pass through the outside of the color changing ring 12 and are connected to the toggle assembly. The side of the partition ring 19 close to the microporous membrane 21 is fixedly connected to one end of the plurality of stirring rods 20.

[0049] More specifically, when it is necessary to stir the color-changing powder inside the powder collecting chamber 23 of the color-changing ring 12, it is only necessary to rotate the toggle assembly. After the toggle assembly is rotated, it will cause the end of the transmission assembly located outside the color-changing ring 12 to rotate, and then the transmission assembly can rotate with the inner gear ring 17 through the end located inside the powder collecting chamber 23. After the inner gear ring 17 rotates, it can cause the partition ring 19 to rotate. After the partition ring 19 rotates, it can cause several stirring rods 20 to rotate, so that the color-changing powder inside the powder collecting chamber 23 can be stirred by the stirring rods 20, which is convenient for operation.

[0050] It should be particularly noted here that a plurality of stirring rods 20 are arranged in a spiral line on the surface of the partition ring 19, so that there is a height difference between the plurality of stirring rods 20, which has a better stirring effect on the color-changing powder.

[0051] As a preferred solution of the present invention, the transmission assembly includes an outer gear 9, a rotating rod 14 and an inner gear 18. The outer gear 9 and the inner gear 18 are respectively sleeved and fixedly connected to the outer walls at both ends of the rotating rod 14. The internal gear 18 is located inside the powder collecting chamber 23, and the internal gear 18 is located on the side of the partition ring 19 away from the microporous membrane 21. The outer gear 9 is located outside the color-changing ring 12. The outer wall of the rotating rod 14 is rotatably connected to the inner wall of the color-changing ring 12 at the penetration point. The internal gear 18 is meshed with the inner gear ring 17, and the external gear 9 is connected to the toggle assembly.

[0052] More specifically, when the toggle assembly is rotated by force, the outer gear 9 will rotate together, and then the outer gear 9 will rotate with the rotating rod 14. After the rotating rod 14 rotates, it can drive the internal gear 18 located inside the powder collecting chamber 23 to rotate. The rotation of the internal gear 18 can engage with the internal gear ring 17 to rotate.

[0053] As a preferred embodiment of the present invention, the No. 2 sealing assembly includes a right support ring 6, a transparent ring 7, an extension ring 8 and an inner horn ring 25, the inner side walls of the right support ring 6 and the inner horn ring 25 are fixedly connected to the outer wall of the male end 2, one side of the right support ring 6 is fixedly connected to one side of the transparent ring 7, the other end of the transparent ring 7 is fixedly connected to one side of the extension ring 8, the inner side wall of the extension ring 8 is slidingly connected to the outer side wall of the No. 1 sealing ring 11, the transparent ring 7 is matched and aligned with the color-changing ring 12, a plurality of through-holes 31 are opened on the surface of the right support ring 6, a plurality of external gears 9 respectively penetrate the plurality of through-holes 31, a side of the right support ring 6 close to the transparent ring 7 is connected to the color-changing ring 12, a side of the right support ring 6 away from the transparent ring 7 is connected to the toggle assembly, and the side of the right support ring 6 away from the transparent ring 7 is also fixedly connected to an end of the inner horn ring 25 close to the transparent ring 7.

[0054] More specifically, during installation, as the female end 1 is inserted into the male end 2, the No. 1 sealing ring 11 will move along the inner wall of the extension ring 8 until the female end 1 and the male end 2 are stably plugged in. At this time, the No. 1 sealing ring 11 will also remain attached to the inner wall of the extension ring 8, thereby continuously sealing the connection between the female end 1 and the male end 2.

[0055] In addition, by providing the transparent ring 7, the color of the color-changing powder can be directly observed through the transparent ring 7 and the color-changing ring 12, so as to know whether water ingress occurs.

[0056] It should be noted here that the outer side walls of the outer horn ring 10 and the inner horn ring 25 are both inclined surfaces. The purpose of this arrangement is that when water enters this position, it can be discharged in time along the inclined surface without accumulation, thereby reducing the probability of water ingress.

[0057] As a preferred solution of the present invention, the support assembly includes a left support ring 4 and a dustproof net 27, the inner wall of the dustproof net 27 is fixedly connected to the outer wall of the male end 2, the outer wall of the dustproof net 27 is fixedly connected to the inner wall of the left support ring 4, and the side of the left support ring 4 close to the right support ring 6 is connected to the toggle assembly.

[0058] More specifically, by providing the left support ring 4, support can be provided on the side of the toggle assembly away from the right support ring 6, thereby increasing the overall stability and preventing tilting and shaking; by providing the dustproof net 27, debris and dust can be prevented from entering the position of the toggle assembly and obstructing the connection between the toggle assembly and the stirring assembly.

[0059] As a preferred embodiment of the present invention, the toggle assembly includes a knob 5, an outer toothed ring 26 and two No. 2 rotating rings 28. A No. 2 rotating opening 30 is provided on the adjacent sides of the right support ring 6 and the left support ring 4. The outer walls of the two No. 2 rotating rings 28 are rotatably connected to the inner walls of the two No. 2 rotating openings 30 respectively. The adjacent sides of the two No. 2 rotating rings 28 are fixedly connected to the two sides of the knob 5 respectively. The inner wall of the knob 5 is fixedly connected to the outer wall of the outer toothed ring 26. The outer toothed ring 26 is meshed with a plurality of external gears 9.

[0060] More specifically, when it is necessary to control the stirring rod 20 to stir the color-changing powder, it is only necessary to turn the knob 5. The knob 5 will maintain relative rotation through the two No. 2 rotating rings 28 and the support of the two No. 2 rotating ports 30, and when the knob 5 is rotated, it will also cause the outer gear ring 26 to rotate coaxially. Then, the outer gear ring 26 can cause the multiple external gears 9 to rotate, thereby causing the partition ring 19 and the multiple stirring rods 20 to rotate.

[0061] As a preferred embodiment of the present invention, two sealing openings 29 are provided on the side of the right support ring 6 close to the transparent ring 7. Two second sealing rings 13 are fixedly connected to the side of the color-changing ring 12 away from the mounting ring 16. The outer walls of the two second sealing rings 13 are respectively slidably connected to the inner walls of the two sealing openings 29.

[0062] More specifically, by providing the sealing openings 29 and the second sealing rings 13, firstly, the connection stability between the color-changing ring 12 and the right support ring 6 can be increased; secondly, it can also prevent water from entering the color-changing ring 12 from the right support ring 6.

[0063] As a preferred embodiment of the present invention, fixing blocks 3 are sleeved and fixedly connected to the outer walls of the male end 2 and the female end 1, and the two fixing blocks 3 are tightly connected by bolts.

[0064] More specifically, by providing the fixing blocks 3, the connection stability between the male end 2 and the female end 1 can be increased.

[0065] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
