Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an AC connector structure with a sealing structure. Background Technology

[0002] As a key connection component in power transmission systems, AC connectors are widely used in industrial equipment, household appliances, and power engineering. Their connection stability and sealing performance directly affect the safety and efficiency of power transmission, and are of great significance for ensuring the normal operation of equipment and avoiding leakage or interference from external impurities.

[0003] In the existing technology, AC connectors are usually composed of a male head, a female head, and a corresponding sleeve. During assembly, the male head and female head are usually connected by direct plugging. Some structures will add a simple rubber gasket to the inner wall of the sleeve. The pressure during plugging will make the rubber gasket fit against the surface of the component, thereby initially improving the sealing effect. The operation process is relatively simple and direct.

[0004] The existing technology has the following drawbacks: the sealing structure design of existing AC connectors is relatively simple, relying only on the rubber pad to adhere to the base of the component. When the connector is used for a long time or is in an environment with vibration, temperature changes, etc., the rubber pad is prone to displacement or decreased adhesion, resulting in weakened sealing performance. External dust, moisture and other impurities can easily enter the interior, which not only affects the stability of power transmission, but may also shorten the service life of the connector. Therefore, an AC connector structure with a sealing structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an AC connector structure with a sealing structure, which aims to improve the poor sealing performance of some existing connectors in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an AC connector structure with a sealing structure, including a sleeve, a female head provided on the inner wall of the sleeve, a connecting tube contacting the right side wall of the sleeve, an inner tube fixedly connected to the inner wall of the connecting tube, a male head provided on the inner wall of the inner tube, a long rod fixedly connected to the right side wall of the sleeve, a rubber ring slidably connected to the inner wall of the connecting tube, a rectangular block fixedly connected to the right side wall of the rubber ring, a movable mechanism provided on the inner wall of the connecting tube, and a reinforcing component provided on the inner wall of the inner tube.

[0007] The movable mechanism includes an inclined block, which is slidably connected to the inner wall of the connecting pipe, and the bottom of the inclined block is elastically connected to the connecting pipe through a movable spring.

[0008] As a further description of the above technical solution:

[0009] The reinforcing component includes a limiting block that is slidably connected to the inner wall of the inner tube. The bottom end of the limiting block is elastically connected to the connecting tube via a moving spring. A rotating ring is elastically connected to the inner wall of the connecting tube via a torsion spring. A pressing block is fixedly connected to the inner wall of the rotating ring.

[0010] As a further description of the above technical solution:

[0011] The inner tube is inserted into the inner wall of the sleeve, and the male head is inserted into the inner wall of the female head.

[0012] As a further description of the above technical solution:

[0013] The long rod is inserted into the inner wall of the rubber ring, and the rubber ring is inserted into the inner wall of the sleeve.

[0014] As a further description of the above technical solution:

[0015] An inclined surface is provided on the upper side of the inclined block, and the right end of the long rod is in contact with the inclined surface.

[0016] As a further description of the above technical solution:

[0017] The inclined block has an inclined groove inside, and the rectangular block is slidably connected to the inner wall of the inclined groove.

[0018] As a further description of the above technical solution:

[0019] The limiting block is inserted into the inner wall of the connecting pipe, and the swivel ring is rotatably connected to the outer wall of the connecting pipe.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the extrusion block is in contact with the upper surface of the limiting block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the male and female heads are inserted, the long rod squeezes the inclined block to move downward, so that the inclined groove pushes the rectangular block to move the rubber ring. As the insertion progresses, the rubber ring and the sleeve are in closer contact and the deformation is increased. Through the dual action of displacement and deformation, the sealing performance of the device is effectively improved.

[0024] 2. In this utility model, during insertion, the tube sleeve squeezes the limiting block downward, so that the limiting block coincides with the groove of the tube sleeve after insertion. Under the action of elasticity, the limiting block is inserted into the groove to form a stable limit. When separating, the rotating ring can be rotated to disengage, which is convenient and does not affect subsequent reuse. Attached Figure Description

[0034] 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.

[0035] Reference Figures 1-3This utility model provides an embodiment of an AC connector structure with a sealed structure, including a sleeve 1. A female connector 2 is provided on the inner wall of the sleeve 1, serving as a key interface for current transmission and forming a stable connection with an external circuit. A connecting tube 3 contacts the right side wall of the sleeve 1, which mates with the sleeve 1 to achieve an overall connection. The connecting tube 3 is made of a material with certain insulation and wear resistance. An inner tube 7 is fixedly connected to the inner wall of the connecting tube 3, providing internal support and limiting, thus enhancing the structural stability of the connecting tube 3. A male connector 4 is provided on the inner wall of the inner tube 7, matching the female connector 2 to achieve effective current conduction. A long rod 5 is fixedly connected to the right side wall of the sleeve 1. A rubber ring 6 is slidably connected to the inner wall of the connecting pipe 3. The rubber ring 6 is made of a highly elastic material and can deform under pressure to achieve a seal. A rectangular block 8 is fixedly connected to the right side wall of the rubber ring 6. A movable mechanism is provided on the inner wall of the connecting pipe 3, and a reinforcing component is provided on the inner wall of the inner pipe 7. The movable mechanism includes an inclined block 9. A slot corresponding to the inclined block 9 is opened on the connecting pipe 3, so that the inclined block 9 can move up and down. The inclined block 9 is slidably connected to the inner wall of the connecting pipe 3. The bottom of the inclined block 9 is elastically connected to the connecting pipe 3 through a movable spring 10. When the inclined block 9 moves downward, the movable spring 10 is compressed. When resetting, the elastic force of the movable spring 10 is used to reset the inclined block 9.

[0036] Reference Figures 4-6 The reinforcing component includes a limiting block 11, which is slidably connected to the inner wall of the inner tube 7. The inner tube 7 has a slot corresponding to the limiting block 11, allowing the limiting block 11 to move vertically. The bottom end of the limiting block 11 is elastically connected to the connecting tube 3 via a moving spring 12. When the limiting block 11 moves downwards, the moving spring 12 is compressed. Upon resetting, the elastic force of the moving spring 12 causes the limiting block 11 to return to its original position. The inner wall of the connecting tube 3 is elastically connected to a rotating ring 14 via a torsion spring 13. When the rotating ring 14 rotates counterclockwise, the torsion spring 13 is compressed. When in position, the spring force of the torsion spring 13 drives the rotating ring 14 to reset. The inner wall of the rotating ring 14 is fixedly connected to the pressing block 15. The limiting block 11 is inserted into the inner wall of the connecting pipe 3. The limiting block 11 is provided with an inclined surface. When the sleeve 1 presses the inclined surface, the limiting block 11 moves downward. The rotating ring 14 is rotatably connected to the outer wall of the connecting pipe 3. The connecting pipe 3 has a slot corresponding to the rotating ring 14 to facilitate the rotation of the rotating ring 14. The outer wall of the pressing block 15 contacts the upper surface of the limiting block 11. When the pressing block 15 presses the limiting block 11, the limiting block 11 moves downward.

[0037] Reference Figure 2 , Figure 3 and Figure 7The inner tube 7 is inserted into the inner wall of the sleeve 1. The insertion fit can ensure the coaxiality of the two and improve the connection accuracy. The male head 4 is inserted into the inner wall of the female head 2. The long rod 5 is inserted into the inner wall of the rubber ring 6. The rubber ring 6 has a rectangular groove corresponding to the long rod 5. The upper side of the inclined block 9 is provided with an inclined surface. The right end of the long rod 5 is in contact with the inclined surface. When the long rod 5 presses the inclined surface, it causes the inclined block 9 to move downward. The inclined block 9 has an inclined groove inside. The rectangular block 8 is slidably connected to the inner wall of the inclined groove. The rubber ring 6 is inserted into the inner wall of the sleeve 1. The sleeve 1 has a groove corresponding to the rubber ring 6.

[0038] Working principle: When connecting male connector 4 and female connector 2, manually align male connector 4 and insert it into the direction of female connector 2. During insertion, as long rod 5 contacts and presses the inclined surface of inclined block 9, inclined block 9 moves downward and presses the movable spring 10. At the same time, the inclined groove on inclined block 9 presses the rectangular block 8, causing the rectangular block 8 to move to the left with rubber ring 6. As male connector 4 and female connector 2 are inserted, rubber ring 6 will make closer contact with sleeve 1 under the push of rectangular block 8. The greater deformation of 6 further enhances the sealing of the device. At the same time, as the sleeve 1 contacts the inclined surface of the limiting block 11, the sleeve 1 will squeeze the inclined surface of the limiting block 11, causing the limiting block 11 to move downward and squeeze the moving spring 12. When the male head 4 and the female head 2 are connected, the limiting block 11 coincides with the slot on the sleeve 1. Under the elastic force of the moving spring 12, the limiting block 11 is inserted into the slot of the sleeve 1, further increasing the stability of the connection between the male head 4 and the female head 2.

[0039] When it is necessary to disconnect the male connector 4 and the female connector 2, manually rotate the rotating ring 14 counterclockwise. The rotating ring 14 will compress the torsion spring 13, and at the same time, the rotating ring 14 will move the compression block 15. When the compression block 15 contacts and compresses the limiting block 11, let the limiting block 11 move downward. When the limiting block 11 separates from the groove on the sleeve 1, manually remove the connecting tube 3 to complete the separation of the male connector 4 and the female connector 2. Then manually release the rotating ring 14. Under the elastic force of the torsion spring 13, the rotating ring 14 moves back to the initial position. At this time, the limiting block 11 also moves back to the initial position. As the long rod 5 no longer contacts the inclined block 9, under the elastic force of the movable spring 10, the inclined block 9 moves back to the initial position. The inclined groove on the inclined block 9 will move the rectangular block 8 to the right. The rectangular block 8 will move back to the initial position with the rubber ring 6.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
