Description

Technical Field

[0001] The present application relates to the technical field of fluid connectors, and in particular to a fluid connector plug and a fluid connector. Background Art

[0002] The fluid connector includes a plug and a socket. The plug is installed on the maniflod, and the socket is installed on the server cold plate. After the server is installed on the cabinet, the socket and the plug are plugged together, and the liquid circulates to achieve the function. Due to processing and design tolerances, the center of the plug and the socket are not aligned, so the plug end product needs to have a floating function that can be compatible with the structural tolerance to achieve docking. Common plug floating structures are generally composed of a housing, a movable valve core, and a spring.

[0003] The structure of the existing floating plug is as follows Figure 1 As shown, the following problems are common:

[0004] (1) In existing floating fluid connectors, the floating housing and spring are separated. When the floating housing floats radially and the mounting housing is displaced to the limit, the spring inside the product will be skewed. The skewed spring will cause wall scraping, valve core jamming or slow rebound, resulting in failure and leakage. To avoid a large degree of spring skew, this structure allows a radial floating range of ±0.5mm. This design cannot achieve a large tolerance floating, and the achievable radial floating range is no more than ±0.5mm. It cannot meet the use requirements for some scenes with large center offset.

[0005] (2) When the floating housing is inserted obliquely, displacement occurs between the floating housing and the installation housing. When the floating housing is tilted, it is squeezed against the sealing ring, which is easily damaged or broken, resulting in product sealing failure and leakage.

[0006] In summary, the sealing reliability of the current floating fluid connector after long-term use needs to be improved. Summary of the invention

[0007] The purpose of the present application is to provide a fluid connector plug and a fluid connector to solve the problem of poor sealing reliability of the fluid connector in the prior art.

[0008] In order to achieve the above objectives, this application is implemented by adopting the following technical solutions:

[0009] In a first aspect, the present application discloses a fluid connector plug, comprising a floating housing and a spring, wherein a spring positioning member is provided in a fluid channel of the floating housing, the spring is arranged in the fluid channel and connected to the spring positioning member, and the spring positioning member is used to limit the position of the bottom end of the spring so that the bottom end of the spring is located in the fluid channel of the floating housing;

[0010] A connecting groove is provided on the connecting surface of the floating shell, and a sealing ring is provided in the connecting groove.

[0011] Furthermore, the spring positioning member is arranged at the end of the fluid channel, and the bottom end of the spring is connected to the top surface of the spring positioning member.

[0012] Furthermore, the outer ring of the spring positioning member is provided with a protrusion, the fluid channel of the floating housing is provided with a groove, and the protrusion is connected to the groove.

[0013] Furthermore, the spring positioning member is connected to the fluid passage of the floating housing via a clamping ring.

[0014] Furthermore, the spring positioning member is welded in the fluid passage of the floating housing.

[0015] Furthermore, the spring positioning member has a flow channel connected to the fluid channel of the floating housing.

[0016] Furthermore, the flow channel of the spring positioning member and the fluid channel of the floating housing are arranged in the same direction.

[0017] Further, the connecting groove is an annular connecting groove, and the sealing ring is interference fit in the annular connecting groove.

[0018] Furthermore, the thickness of the sealing ring is greater than the depth of the connecting groove.

[0019] In a second aspect, the present application discloses a fluid connector, comprising a socket and the plug described in any one of the first aspects.

[0020] The beneficial effects of this application are:

[0021] The present application ensures the sealing reliability of the fluid connector through the combined effect of two aspects of improvement; on the one hand, by adding a spring positioning piece, the bottom end of the spring is located in the fluid channel of the floating shell, which can prevent the spring from being skewed due to the radial offset of the movable shell during use, and avoid product leakage caused by spring jamming and abnormal rebound, thereby greatly improving the sealing reliability of the connector; on the other hand, by arranging the sealing ring on the connecting surface of the floating shell, when the floating shell is obliquely inserted or floated in translation during use, the sealing ring and the floating shell move together on the mating plane of the mounting shell, which can effectively prevent the sealing ring from being damaged or broken, thereby improving the sealing reliability of the connector.

[0027] In order to make the technical means, creative features, objectives and effects achieved by this application easy to understand, this application is further explained below in conjunction with specific implementation methods.

[0028] It should be noted that in the description of the present application, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application rather than requiring that the present application must be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present application refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] The present application provides a fluid connector plug structure that can achieve greater floating, so as to solve the problems of abnormal spring-induced valve core rebound and failure leakage in existing products, small radial floating tolerance and failure leakage caused by damage to the sealing ring.

[0030] like Figure 2-Figure 4 As shown, a fluid connector plug includes a floating shell 1 and a spring 2, characterized in that a spring positioning member 3 is provided in the fluid channel of the floating shell 1, the spring 2 is arranged in the fluid channel and connected to the spring positioning member 3, the spring positioning member 3 is used to limit the position of the bottom end of the spring 2 so that the bottom end of the spring 2 is located in the fluid channel of the floating shell 1; a connecting groove is provided on the connecting surface of the floating shell 1, and a sealing ring 4 is provided in the connecting groove.

[0031] When the present application is used, when the plug is inserted into the corresponding socket, the floating housing 1 enters the socket as the plug is pushed forward. The sealing ring 4 is located in the connection groove of the connection surface of the floating housing 1, and begins to contact and compress, forming a seal to prevent fluid leakage during the connection process. Since the sealing ring 4 is located in the floating housing 1, when the floating housing 1 is obliquely inserted or floated in translation, the sealing ring 4 and the floating housing 1 move together on the matching plane of the mounting housing, which can effectively prevent the sealing ring 4 from being damaged or broken, thereby improving the sealing reliability of the connector.

[0032] Due to the addition of the spring positioning member 3, the bottom end of the spring can be located in the fluid channel of the floating housing, so that the spring 2 and the floating housing 1 are combined into a whole, and the spring 2 moves with the floating housing 1 to achieve radial floating. The spring positioning member 3 can prevent the spring from being skewed due to the radial deviation of the movable housing, and avoid product leakage caused by spring jamming and abnormal rebound, which can greatly improve product reliability. The spring 2 and the floating housing 1 are an integrated structure, and there is no need to consider the skew of the spring caused by the movement of the floating housing, and a large radial floating can be achieved.

[0033] Once connected in place, the fluid can flow freely through the fluid channel in the floating housing 1. Due to the presence of the spring and the spring locator 3, the connector can maintain good sealing and prevent fluid leakage even if there are pressure fluctuations or slight physical displacements inside the system.

[0034] In one embodiment, the spring locator 3 is arranged at the end of the fluid channel, and the bottom end of the spring 2 is connected to the top surface of the spring locator 3. In the present application, the bottom end of the spring 2 is connected to the top surface of the spring locator 3 by contact, that is, the spring 2 is placed on the spring locator 3. By arranging the spring locator 3 at the end of the fluid channel and directly connecting it to the bottom end of the spring, the installation and adjustment of the spring 2 and the spring locator 3 are easier.

[0035] In a further embodiment, the outer ring of the spring positioning member 3 is provided with a protrusion, and a groove is provided in the fluid passage of the floating housing 1, and the protrusion is connected to the groove. The mechanical engagement between the protrusion and the groove ensures that the spring positioning member 3 is firmly positioned in the floating housing 1, avoiding displacement caused by vibration or pressure changes during use, and improving the stability of the connector.

[0036] In one embodiment, the spring locator 3 is connected to the fluid channel of the floating housing 1 through a collar. In another embodiment, the spring locator 3 is welded to the fluid channel of the floating housing 1. The spring locator can be fixed by a collar or welding, providing a variety of installation options, and the most suitable fixing method can be selected according to specific application requirements. The collar connection method facilitates the rapid disassembly and assembly of the spring locator, which is conducive to daily maintenance and component replacement, reducing maintenance costs and time; welding can form a more stable and reliable fixation.

[0037] In one embodiment, the spring positioning member 3 has a flow channel connected to the fluid channel of the floating housing 1. Further, the flow channel of the spring positioning member 3 and the fluid channel of the floating housing 1 are arranged in the same direction. The spring positioning member 3 has a flow channel connected to the fluid channel, and the direction of the flow channel is consistent with the main channel, which ensures the continuity and unobstructed flow of the fluid, reduces the fluid resistance, and is conducive to improving the fluid transmission efficiency.

[0038] In one embodiment, the connection groove is an annular connection groove, and the sealing ring 4 is interference-fitted in the annular connection groove. The thickness of the sealing ring 4 is greater than the depth of the connection groove. The annular connection groove is fitted with the sealing ring 4 with interference fit, which not only simplifies the sealing structure, but also ensures a good sealing effect, and is particularly suitable for high-pressure working conditions, and improves the tightness and safety of the connection. The thickness of the sealing ring 4 is greater than the depth of the connection groove. Such a design can ensure that the sealing ring is sufficiently deformed when subjected to pressure, thereby achieving a better sealing effect and preventing any potential leakage.

[0039] The present application also discloses a fluid connector, including a socket and a plug of any of the above embodiments. When the connector is used, the floating housing 1 is plugged into the mounting housing 5, the sealing ring 4 on the floating housing contacts the end surface of the mounting housing 5 to form a good seal, and the spring positioning member 3 in the floating housing 1 limits the position of the spring 2 so that the spring will not be skewed, thereby preventing the problem of wall scraping, valve core jamming or slow rebound causing failure leakage.

[0040] The present application has the following advantages: the plug floating housing is an integrated structure with the spring and the sealing ring, and can realize overall radial floating. During the floating process, there will be no spring deflection, abnormal valve core rebound, sealing ring damage, etc., and at the same time, a large radial floating effect can be achieved, which greatly improves the reliability of the product and the application scenarios of the product.

[0041] It is known from common technical knowledge that the present application can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
