Description

Technical Field

[0001] This invention relates to the field of connectors, and in particular to a magnetically levitated liquid-cooled quick connector. Background Technology

[0002] Quick-connect couplings are the most convenient plug-and-play connection method, especially advantageous in challenging situations where air pipe connections are difficult or in confined spaces. To use, align the quick-connect coupling's flexible flared end with the bus's water pipe. Hold the handle and rotate the locking tube; the inner tube moves inward relative to the locking tube, compressing the locking section of the inner tube with its flared end. This reduces the longitudinal groove of the locking section, causing it to press tightly against the flexible flared end sealing sleeve, creating a tight seal between the sleeve and the water pipe. To remove the pipe, rotate the handle in the opposite direction; the locking tube retracts, allowing the inner tube locking section and the flexible flared end sealing sleeve to return to their natural state, making it easy to pull out the quick-connect coupling. Floating couplings are also a type of quick-connect coupling.

[0003] Existing floating connectors typically use a fixed quick-connect socket or plug as a power source, then mechanically move the corresponding socket and plug parts to achieve floating. This mechanical floating increases relative friction, making the quick-connect's floating action less effective for functions such as correcting angular deviations. Therefore, it is necessary to research a new technical solution to address these problems. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the existing technology, and its main objective is to provide a magnetic levitation liquid-cooled quick connector, which can effectively solve the problems of existing floating connectors that use mechanical floating, have high friction, and poor floating effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetically levitated liquid-cooled quick connector includes a housing, a first magnet, a connector body, a positioning pin, and a second magnet. The housing has an insertion cavity with one end open. The first magnet is disposed on the inner peripheral sidewall of the insertion cavity. The connector body is radially and axially floating in the insertion cavity. A limiting hole is formed on the connector body. The positioning pin is disposed on the housing and extends inward into the insertion cavity. The positioning pin cooperates with the limiting hole and extends into the limiting hole to limit the position of the connector body. The second magnet is disposed on the outer peripheral sidewall of the connector body. The second magnet and the first magnet are of the same pole and repel each other, causing the connector body to float radially.

[0007] As a preferred embodiment, the first magnet is a sheet-like structure, and there are multiple first magnets, which are respectively located on the inner peripheral sidewalls of the insertion cavity. Correspondingly, there are also multiple second magnets, which are respectively located on the outer peripheral sidewalls of the connector body. Each second magnet and the corresponding first magnet are like poles that repel each other, causing the connector body to float radially.

[0008] As a preferred embodiment, the insertion cavity is rectangular, and two first magnets are embedded in each long side of the inner wall of the insertion cavity. Correspondingly, the cross-section of the outer wall of the connector body is also rectangular, and two second magnets that cooperate with the first magnets are embedded in each long side of the outer wall of the connector body.

[0009] As a preferred embodiment, the lower end of the housing integrally extends downward with a mounting plate, and the mounting plate is provided with a limiting groove and a fixing hole for external engagement.

[0010] As a preferred embodiment, a reinforcing rib is integrally formed between the mounting plate and the lower end face of the housing. The reinforcing rib is located in the middle of the mounting plate, and the aforementioned limiting groove and fixing hole are two symmetrically arranged along the left and right sides of the reinforcing rib.

[0011] As a preferred embodiment, the housing sidewall has a through-hole, through which the positioning pin is fixedly mounted on the housing and extends into the insertion cavity.

[0012] As a preferred embodiment, the positioning pin includes a first pin extending laterally and a second pin extending longitudinally. Correspondingly, the limiting hole includes a first limiting hole extending laterally and a second limiting hole extending longitudinally. The first pin and the second pin extend inward into the corresponding first limiting hole and second limiting hole, respectively, to limit the position of the connector body.

[0013] As a preferred embodiment, there are two first limiting holes arranged symmetrically on the left and right, and one second limiting hole is provided through the front and rear end faces of the connector body; correspondingly, there are two first pins arranged symmetrically on the left and right, which are respectively provided on the left and right side walls of the housing, and the two first pins extend into the corresponding first limiting holes respectively, and there is one second pin, which is provided on one side wall of the housing and passes through the second limiting hole to be fixed to the other side wall of the housing.

[0014] As a preferred embodiment, the connector body has a first connecting part and a second connecting part integrally protruding outward at its upper and lower ends, respectively. The first connecting part extends upward into the insertion cavity, and a through hole is passed through the lower end face of the housing. The second connecting part extends downward into the insertion cavity through the through hole.

[0015] As a preferred embodiment, the first connecting part and the second connecting part are both arranged symmetrically from left to right, and correspondingly, the through holes are also arranged symmetrically from left to right, with each second connecting part extending downward into the insertion cavity through the corresponding through hole.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] The first magnet is disposed on the inner peripheral sidewall of the insertion cavity; a limiting hole is formed on the connector body; a positioning pin is disposed on the housing and extends inward into the insertion cavity, the positioning pin engages with the limiting hole and extends into the limiting hole to limit the connector body; and a second magnet is disposed on the outer peripheral sidewall of the connector body. The second magnet and the first magnet are of the same pole and repel each other, causing the connector body to float radially. Through the principle of like pole repulsion between the first and second magnets, magnetic levitation floating is achieved. Compared with the existing mechanical floating, the socket or plug can float simultaneously, and the relative friction is reduced during floating. The floating of the quick connector is more flexible in correcting angular deviations, the floating effect is better, and it can also effectively increase the service life of the product.

[0036] The housing 10 has an insertion cavity 101 with one open end. In this embodiment, a mounting plate 11 extends integrally downward from the lower end of the housing 10. The mounting plate 11 has a limiting groove 102 and a fixing hole 103 for external engagement. The limiting groove 102 facilitates positioning and installation with the external environment. A reinforcing rib 12 is integrally formed between the mounting plate 11 and the lower end face of the housing 10. The reinforcing rib 12 is located in the middle of the mounting plate 11 and is used to enhance the structural strength between the mounting plate 11 and the housing 10. The aforementioned limiting groove 102 and fixing hole 103 are two symmetrically arranged along the left and right sides of the reinforcing rib 12. The symmetrically arranged fixing holes 103 are used to ensure the stability of the connection between the housing 10 and the external environment. The insertion cavity 101 is rectangular. An installation hole 104 penetrates the side wall of the housing 10. A through hole 105 penetrates the lower end face of the housing 10.

[0037] The first magnet 20 is disposed on the inner peripheral sidewall of the insertion cavity 101; in this embodiment, the first magnet 20 is a sheet structure, and there are multiple first magnets 20, which are respectively located on each inner peripheral sidewall of the insertion cavity 101; two first magnets 20 are embedded on each long side of the inner sidewall of the insertion cavity 101.

[0038] The connector body 30 is radially and axially floatingly disposed in the insertion cavity 101; a limiting hole 301 is provided on the connector body 30; in this embodiment, the outer wall cross section of the connector body 30 is also rectangular; the limiting hole 301 includes a first limiting hole 302 extending laterally and a second limiting hole 303 extending longitudinally; the first limiting hole 302 is two symmetrically arranged on the left and right, and the second limiting hole 303 is one that penetrates the front and rear end faces of the connector body 30; the upper and lower ends of the connector body 30 are respectively integrally provided with a first connecting part 31 and a second connecting part 32 protruding outwards, the first connecting part 31 extending upwards out of the insertion cavity 101 so that it can be connected to another connector, and the second connecting part 32 extending downwards out of the insertion cavity 101 through a through hole 105; the first connecting part 31 and the second connecting part 32 are both two symmetrically arranged on the left and right, and correspondingly, the aforementioned through hole 105 is also two symmetrically arranged on the left and right, and each second connecting part 32 extends downwards out of the insertion cavity 101 through the corresponding through hole 105.

[0039] The positioning pin 40 is disposed on the housing 10 and extends inward into the insertion cavity 101. The positioning pin 40 cooperates with the limiting hole 301 and extends into the limiting hole 301 to limit the connector body 30. In this embodiment, the positioning pin 40 is fixedly installed on the housing 10 through the mounting hole 104 and extends inward into the insertion cavity 101. The positioning pin 40 includes a first pin 41 extending laterally and a second pin 42 extending longitudinally. The first pin 41 and the second pin 42 extend inward into the corresponding first limiting hole 302 and the second limiting hole 303 respectively to limit the connector body 30. There are two first pins 41 arranged symmetrically on the left and right sides, which are respectively disposed on the left and right side walls of the housing 10. The two first pins 41 extend into the corresponding first limiting hole 302. There is one second pin 42, which is disposed on one side wall of the housing 10 and passes through the second limiting hole 303 to be fixed to the other side wall of the housing 10, so that the positions of the first pin 41 and the second pin 42 do not affect each other.

[0040] The second magnet 50 is disposed on the outer peripheral sidewall of the connector body 30. The second magnet 50 and the first magnet 20 are mutually repulsive due to their common poles, which causes the connector body 30 to float radially. In this embodiment, there are also multiple second magnets 50. The multiple second magnets 50 are respectively located on the outer peripheral sidewall of the connector body 30, and each second magnet 50 and the corresponding first magnet 20 are mutually repulsive due to their common poles, which causes the connector body 30 to float radially. The long side of the outer sidewall of each connector body 30 is provided with two second magnets 50 that cooperate with the first magnet 20.

[0041] The assembly process of this embodiment is described in detail below:

[0042] During assembly, the first magnet 20 is first assembled on the inner peripheral side wall of the insertion cavity 101, and the second magnet is assembled on the outer peripheral side wall of the connector body 30. Then, the connector body 30 is inserted into the insertion cavity 101. After the connector body 30 is inserted into place, the first pin 41 and the second pin 42 are inserted into the housing 10 and respectively extended into the first limiting hole 302 and the second limiting hole 303 to limit the connector body 30.

This achieves magnetic levitation by utilizing the principle of repulsion between the like poles of the first and second magnets. Compared to existing mechanical floating mechanisms, this allows for simultaneous floating of the socket or plug, and reduces relative friction during floating. The quick-connect connector's floating mechanism is more flexible in correcting angular deviations, provides a better floating effect, and effectively increases the product's lifespan.
