Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plug-in connectors, in particular to a waterproof plug-in connector based on dynamic sealing compensation. BACKGROUND

[0002] The waterproof connector refers to an electronic connector with waterproof function. The waterproof connector adopts a special sealing structure and waterproof material, and can effectively prevent water, dust and other impurities from entering the connection point. Due to the quick plug-in design and waterproof function of the waterproof plug-in connector, the waterproof plug-in connector is widely used in various fields.

[0003] The existing waterproof plug-in connector seals the connection by a waterproof ring to prevent water from entering. Although the waterproof function can be achieved by the waterproof ring, the state of the waterproof ring is static. If the waterproof ring is improperly installed or the external water volume or water pressure is too large, water may enter the inside of the plug-in connector through the waterproof ring. This not only loses the waterproof effect, but also causes short circuit and leakage, which is very dangerous. In addition, the wire of the existing waterproof connector is only plugged by a plug to block the gap between the wire and the wire hole. During use, if the wire is pulled by external force, the wire will be pulled by the pulling force, which will cause poor contact or even fall off, and the wire will also move the plug, so that a gap is formed between the plug and the inner wall of the wire hole, and water seeps into the inside. Therefore, the waterproof effect and sealing stability of the existing waterproof plug-in connector are poor.

[0004] Therefore, the waterproof plug-in connector based on dynamic sealing compensation is proposed to solve the above problems. SUMMARY

[0035] Specifically, the plug 703 preliminarily seals and plugs the threading hole 3, when water penetrates into the inside of the threading hole 3 through the plug 703, the water enters the inside of the rubber ring 710 through the water absorption openings 711 and is absorbed by the water absorption resin, the water absorption resin expands after absorbing water, so as to extrude the rubber ring 710 to make it more closely fit the inner wall of the threading hole 3, and the sealing and plugging effect is further improved.

[0036] The inner wall of the threading hole 3 is provided with a mounting groove, and an annular magnet 11 is fixedly installed in the mounting groove, the magnetic blocks 709 have the same magnetic pole at the ends close to the annular magnet 11, when the anti-pulling plugging piece 7 enters the threading hole 3, the annular magnet 11 repels the magnetic blocks 709, so as to make the inclined rods 705 contract and shorten, thereby making the anti-pulling plugging piece 7 more smoothly enter the threading hole 3 to realize sealing.

[0037] The plug 703 is a circular ring shape with an open lower end. An inner wall of the plug 703 is fixedly connected with a plurality of arc-shaped magnetic sheets 12 which are uniformly distributed. The arc-shaped magnetic sheets 12 are opposite to the magnetic poles of the annular magnet 11 which are close to each other. The arc-shaped magnetic sheets 12 attract the annular magnet 11, so that the outer ring of the plug 703 is tightly attached to the annular magnet 11, the sealing state of the plug 703 is more stable, the plug 703 is prevented from shaking together with the wire 4 to cause a gap phenomenon when the wire 4 is pulled, the sealing effect is better, the diameter of the inner ring of the plug 703 is smaller than the outer diameter of the wire 4, the inner ring of the plug 703 is tightly attached to the wire 4, and the sealing effect is improved.

[0039] Working principle: before use, the anti-pulling plug 7 is inserted into the wire 4, and then the anti-pulling plug 7 and the wire 4 are inserted into the wire hole 3. When the anti-pulling plug 7 enters the wire hole 3, the annular magnet 11 repels the magnetic block 709, so that the inclined rod 705 is contracted and shortened, so that the anti-pulling plug 7 can enter the wire hole 3 more smoothly to realize sealing. After the magnetic block 709 moves away from the annular magnet 11, the repulsion force disappears, and the inclined rod 705 is elongated, so as to press and clamp the block 706 and the support block 707, so that the clamping block 706 and the support block 707 press the wire 4 and the inner wall of the wire hole 3, and the anti-pulling plug 7 is fixed in the wire hole 3. At the same time, the plug 703 and the arc-shaped magnetic sheet 12 move to the position of the annular magnet 11, the arc-shaped magnetic sheet 12 attracts the annular magnet 11, so that the outer ring of the plug 703 is tightly attached to the annular magnet 11, the sealing state of the plug 703 is more stable, the plug 703 is prevented from shaking together with the wire 4 to cause a gap phenomenon when the wire 4 is pulled, the sealing effect is better, the diameter of the inner ring of the plug 703 is smaller than the outer diameter of the wire 4, the inner ring of the plug 703 is tightly attached to the wire 4, and the sealing effect is improved. After the anti-pulling plug 7 is installed, the wire 4 is connected with the plug-in male seat 1 and the plug-in female seat 2. After the wire 4 is connected with the plug-in male seat 1 and the plug-in female seat 2, the plug-in male seat 1 and the plug-in female seat 2 are plugged together. The sealing plug 10 can preliminarily seal the gap between the plug-in male seat 1 and the plug-in female seat 2 to preliminarily prevent water from entering the plug-in mounting hole 5. Meanwhile, the plug female seat 2 moves towards the inside of the plug installation hole 5, and the stopper 9 also moves synchronously, thereby extruding the extrusion block 604 and the extrusion plate 603 to move together, the extrusion plate 603 moves to extrude the sealing air bag 602, so that the sealing air bag 602 expands to extend to the outer surface of the plug female seat 2 to realize secondary sealing. When water penetrates into the plug installation hole 5 through the sealing plug 10, the water enters the C-shaped box 601 through the water inlet hole 606. At this time, the compensation layer 605 can absorb the penetrated water. After absorbing the water, the compensation layer 605 expands to extrude the extrusion plate 603 to move again, thereby further extruding the sealing air bag 602, so that the sealing air bag 602 further expands to be more closely attached to the outer surface of the plug female seat 2, which can more effectively block the water from penetrating into the plug installation hole 5. The more water penetrates, the more the compensation of the sealing air bag 602, and the more closely the sealing air bag 602 is attached to the plug female seat 2, so as to realize dynamic sealing according to the size of the water penetration, and further improve the waterproof effect. After the plug is completed, the plug male seat 1 and the plug female seat 2 are locked by the buckle 13 and the clamping block 14. When in use, the plug 703 preliminarily seals and blocks the threading hole 3. When water penetrates into the threading hole 3 through the plug 703, the water enters the inside of the rubber ring 710 through the water suction port 711 and is absorbed by the water absorption resin. After the water absorption resin absorbs water, it expands to extrude the rubber ring 710 to be more closely attached to the inner wall of the threading hole 3, thereby further improving the sealing and blocking effect. When the wire 4 is pulled, the extrusion force generated by the inclined rod 705 can make the clamping block 706 clamp the wire 4 more tightly, thereby avoiding the influence of the pulling of the wire 4, making the connection of the wire 4 more stable, and also avoiding the phenomenon of poor contact caused by pulling.

[0040] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
