Description

Technical Field

[0001] This utility model relates to the field of watertight connector technology, specifically a watertight vacuum connector. Background Technology

[0002] Electrical connectors, as fundamental components for electrical transmission and signal delivery, are widely used in various electronic systems. With the development of marine science and technology, watertight connectors, as important components for underwater electrical and surface terminal equipment, are in increasing demand, and their watertight reliability and cost are receiving more and more attention.

[0003] Currently available watertight connectors are mostly deep-diving connectors, which are generally large in size and have high cost. Once moisture or water enters the sealing area where the socket and plug meet, the insulation performance of the existing watertight connectors will decrease, affecting the insulation effect and even leading to insulation failure.

[0004] Therefore, we propose a watertight vacuum connector. Utility Model Content

[0005] The purpose of this invention is to provide a watertight vacuum connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a watertight vacuum connector, comprising a first connector and a second connector. A male connector is provided at the center of one end of the first connector. A limiting protrusion ring located outside the male connector is integrally connected to one end of the first connector. A contraction airbag is provided inside the first connector. A movable groove is provided on the side of the first connector facing the limiting protrusion ring. A communicating groove located outside the contraction airbag is provided on the outer circumferential surface of the first connector. A threaded sleeve located outside the male connector is rotatably connected to the outer circumferential surface of the limiting protrusion ring. A telescopic airbag is fixedly installed inside the movable groove. A connecting conduit is provided on one side of the telescopic airbag. The other end of the connecting conduit is fixedly installed to one side of the contraction airbag. A retaining ring located inside the movable groove is fixedly installed on the other side of the telescopic airbag. A female connector adapted to the male connector is provided at one end of the second connector. A threaded post wrapped around the female connector is integrally provided at one end of the second connector.

[0007] Optionally, a sealing ring is fixedly installed on one side of the limiting protrusion ring, which is located inside the threaded sleeve. The sealing ring is in tight contact with the inner wall of the threaded sleeve. An installation groove is provided at the end of the threaded column, and an annular ring is installed inside the installation groove. The annular ring is in tight contact with the other side of the limiting protrusion ring.

[0008] Optionally, the second connector has another contraction airbag inside, another movable groove is provided on one side of the second connector, another telescopic airbag is provided inside the other movable groove and communicates with the contraction airbag, and another clamping ring located inside the other movable groove is fixedly installed on the other side of the other telescopic airbag.

[0009] Optionally, the movable groove is not connected to the cavity where the contraction airbag is installed, and the connecting conduit passes through the side wall between the movable groove and the cavity where the contraction airbag is installed.

[0010] Optionally, the other ends of the first connector and the second connector are sealed and fixedly installed with the wires to be connected, and the first connector and the second connector have the same shape and diameter.

[0011] Optionally, the first connector, the male connector, and the limiting protrusion are arranged on the same axis, and the second connector, the female connector, the threaded post, and the mounting groove are arranged on the same axis.

[0012] Optionally, the diameter of the threaded sleeve is larger than the diameter of the first connector, the threaded sleeve is threadedly connected to the threaded post, and the diameter of the other clamping ring is larger than the diameter of the threaded post.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This watertight vacuum connector, by setting a contraction air bladder and a telescopic air bladder, when the male connector and the female connector are mated, the threaded sleeve is rotated to fix the first connector and the second connector. When the first connector and the second connector are placed underwater, the water pressure compresses the contraction air bladder, which in turn allows air in the contraction air bladder to enter the telescopic air bladder through the connecting conduit, causing the telescopic air bladder to expand. This causes the clamping rings on the first connector and the second connector to abut against the two ends of the threaded sleeve, preventing liquid from entering the connector and causing insulation failure.

[0015] 2. This watertight vacuum connector features a limiting protrusion ring. When the threaded sleeve is rotated, the annular ring abuts against the limiting protrusion ring, creating a seal. This seals the male and female connectors from the outside. Simultaneously, the sealing ring abuts against the threaded sleeve, further enhancing the sealing effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a watertight vacuum connector, including a first connector 1 and a second connector 2. A male connector 3 is provided at the middle of one end of the first connector 1. A limiting protrusion 12 located outside the male connector 3 is integrally connected to one end of the first connector 1. A contraction airbag 4 is provided inside the first connector 1. A movable groove 16 is formed on the side of the first connector 1 facing the limiting protrusion 12. A connecting groove 5 located outside the contraction airbag 4 is formed on the outer peripheral surface of the first connector 1. A threaded sleeve 9 located outside the male connector 3 is rotatably connected to the outer peripheral surface of the limiting protrusion 12. A telescopic airbag 7 is fixedly installed inside the movable groove 16. A connecting conduit 6 is provided on one side of the telescopic airbag 7. The other end of the connecting conduit 6 is fixedly installed to one side of the contraction airbag 4. A device located inside the movable groove 16 is fixedly installed on the other side of the telescopic airbag 7. The first connector 1 and the second connector 2 are provided with a tightening ring 8 and a connecting female 11 adapted to the connecting male 3 at one end. The second connector 2 is integrally provided with a threaded post 10 wrapped around the connecting female 11 at one end. By setting a contraction airbag 4 and a telescopic airbag 7, when the connecting male 3 and the connecting female 11 are connected, the threaded sleeve 9 is rotated to fix the first connector 1 and the second connector 2. When the connected first connector 1 and the second connector 2 are put underwater, the water pressure squeezes the contraction airbag 4, and the air in the contraction airbag 4 enters the telescopic airbag 7 through the connecting conduit 6, causing the telescopic airbag 7 to extend. This causes the tightening ring 8 of the first connector 1 and the second connector 2 to abut against the two ends of the threaded sleeve 9 respectively, preventing liquid from entering the connector and causing insulation failure.

[0023] A sealing ring 13 is fixedly installed on one side of the limiting protrusion ring 12, located inside the threaded sleeve 9. The sealing ring 13 abuts against the inner wall of the threaded sleeve 9. An installation groove 15 is provided at the end of the threaded post 10. An annular ring 14 is installed inside the installation groove 15. The annular ring 14 abuts against the other side of the limiting protrusion ring 12. Another contraction airbag 4 is provided inside the second connector 2. Another movable groove 16 is provided on one side of the second connector 2. Another telescopic airbag 7, which is connected to the contraction airbag 4, is provided inside the other movable groove 16. Another clamping ring 8 is fixedly installed on the other side of the other telescopic airbag 7, located inside the other movable groove 16. The movable groove 16 is not connected to the cavity where the contraction airbag 4 is installed. The connecting conduit 6 passes through the side wall between the movable groove 16 and the cavity where the contraction airbag 4 is installed. The other end of the first connector 1 and the second connector 2 is sealed and fixedly installed with the wire to be connected. The first connector 1 and the second connector 2 have the same shape and diameter. The first connector 1, the male connector 3 and the limiting protrusion ring 12 are arranged coaxially. The second connector 2 is arranged coaxially with the female connector 11, the threaded post 10 and the mounting groove 15. The diameter of the threaded sleeve 9 is larger than the diameter of the first connector 1. The threaded sleeve 9 is threadedly connected to the threaded post 10. The diameter of the other clamping ring 8 is larger than the diameter of the threaded post 10. By setting the limiting protrusion ring 12, when the threaded sleeve 9 is rotated, the annular ring 14 is clamped to the limiting protrusion ring 12, and the set annular ring 14 forms a sealing state, thereby insulating the male connector 3 and the female connector 11 from the outside. At the same time, the set sealing ring 13 is clamped to the threaded sleeve 9, thereby sealing again and increasing the sealing effect.

[0024] Working principle:

[0025] After the male connector 3 and the female connector 11 are mated, the threaded sleeve 9 is rotated to fix the first connector 1 and the second connector 2. When the connected first connector 1 and the second connector 2 are placed underwater, the water pressure compresses the air bladder 4, causing the air in the air bladder 4 to enter the telescopic air bladder 7 through the connecting conduit 6, thus extending the telescopic air bladder 7. This causes the clamping rings 8 on the first connector 1 and the second connector 2 to abut against both ends of the threaded sleeve 9, preventing liquid from entering the connector and causing insulation failure. When the threaded sleeve 9 is rotated, the annular ring 14 abuts against the limiting protrusion ring 12, forming a seal and insulating the male connector 3 and the female connector 11 from the outside. At the same time, the sealing ring 13 abuts against the threaded sleeve 9, further sealing the connector and increasing the sealing effect.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
