Description

Technical Field

[0001] The present invention relates to a connector, and particularly to a floating connector. Background Art

[0002] A connector is a commonly used device. In an application environment such as a server, a connector is required to guide a cooling liquid from an outlet pipe (such as a cooling liquid source) to an inlet pipe (such as the interior of the server). In some cases, the pipe connection of the cooling liquid is not a permanent connection but a temporary connection. That is to say, the connector may be switched between different servers. It may be connected to one server during a period of use, and connected to another server during another period.

[0003] Therefore, on the one hand, it is expected that the connector has a quick connection function with the server to allow for convenient and quick switching of the connection method. Moreover, it is expected that the connector has a floating connection function to ensure alignment between the connector and the inlet pipe even when there is a certain error between the installation environment of the connector and the inlet pipe. On the other hand, it is expected that the connector can provide a force feedback function in the connection direction so that the user can know whether the connection is in place, thus avoiding an unstable connection.

[0062] Although the present invention is illustrated and described herein with reference to specific embodiments, the invention should not be limited to the details shown. Rather, various modifications may be made within the scope of the equivalent solutions of the claims without departing from the invention.

[0063] The directional descriptions such as "front", "rear", "upper", "lower", etc. involved herein are only for convenience of understanding, and the present invention is not limited to these directions, but can be adjusted according to the actual situation.

[0064] Refer to Figures 1A to 2Overall description of the connector 100 according to the present application. The connector 100 includes a housing 110, a pipe 120, a gasket 140, a snap ring 150, a base 160, an indicator 170, a first floating spring 191, a second floating spring 192, a pin 193, and a bolt 194.

[0065] The base 160 is mounted to a first object, such as a circuit board. The first object is mounted to a second object, such as a chassis, by other connection means (such as bolt connection, plug connection, welding, etc.) not shown in the present application. One end of the pipe 120 is connected to a fluid pipe (not shown), and the other end is connected to a joint (not shown) provided on the second object. Due to possible manufacturing tolerances or installation tolerances between the first object and the second object, the pipe 120 needs to be floatingly connected to the joint of the second object.

[0066] The connector 100 of the present application is designed to achieve floating functions in the longitudinal, transverse, and vertical directions. The longitudinal direction is the extending direction of the pipe 120, and the transverse and vertical directions are substantially perpendicular to the longitudinal direction. The longitudinal, transverse, and vertical directions are only for easy understanding and do not limit the setting direction of the connector 100 of the present application, and the longitudinal, transverse, and vertical directions do not have to be strictly perpendicular to each other.

[0067] In this embodiment, a plurality of gaskets 140 are respectively sleeved on the pipe 120 and disposed at both ends of the housing 110, thus preventing the pipe 120 from tilting relative to the housing 110. The snap ring 150 is disposed at at least one end of the pipe 120 to prevent the pipe 120 from detaching from the housing 110.

[0068] Refer to Figures 3A to 4B Generally describe the floating connection between the base 160 and the housing 110.

[0069] The base 160 is fixedly disposed on a first object (not shown), and the housing 110 is floatingly disposed on the base 160 in the longitudinal direction. The base 160 can be, for example, embedded in the housing 110 to reduce the overall size of the connector 100. However, this is not necessary. The base 160 can be disposed outside the housing 110, or can have a size larger than the housing 110 and accommodate the housing 110.

[0070] The housing 110 can float between a first longitudinal position and a second longitudinal position relative to the base 160. Figure 3A And Figure 3B Show the housing 110 in the first longitudinal position, where the first end wall 113 of the housing 110 abuts against the base 160. Figure 4A And Figure 4B Show the housing 110 in the second longitudinal position, where the second end wall 114 of the housing 110 abuts against the base 160.

[0071] The first floating spring 191 is disposed between the housing 110 and the base 160 to achieve longitudinal floating. More specifically, the first floating spring 191 biases the housing 110 relative to the base 160 towards Figure 4A and Figure 4B the second longitudinal position shown. Thus, when the pipe 120 is not connected to the second object, the housing 110 (and the pipe 120 accommodated in the housing 110) is held at the second longitudinal position by the first floating spring 191. When the pipe 120 is connected to the second object and there is a tolerance between the first object and the second object, the housing 110 and the pipe 120 can float longitudinally and deviate from the second longitudinal position. The first longitudinal position is the maximum longitudinal floating position of the housing 110 and the pipe 120, so the distance between the first longitudinal position and the second longitudinal position is the maximum longitudinal floating stroke.

[0072] Returning to Figure 2 , the pipe 120 is disposed in the housing 110, and the second floating spring 192 is disposed between the pipe 120 and the housing 110 to achieve lateral floating, vertical floating, and tilting floating. The tilting floating means that the pipe 120 tilts laterally, vertically, or a combination of both. For example, the first end 121 of the pipe 120 can be slightly lower or higher than the second end 122 (see Figure 6 ), so as to flexibly adapt to the tolerance between the first object and the second object. In this embodiment, a plurality of second floating springs 192 are disposed around the periphery of the pipe 120, thus achieving lateral floating, vertical floating, and tilting floating of the pipe 120 relative to the housing 110.

[0073] Referring to Figures 5A to 5B describe the specific structure of the housing 110. In this embodiment, the housing 110 is assembled by a first housing 110a and a second housing 110b through bolts 194, which is convenient for processing and manufacturing. In other embodiments, the housing 110 can be integrally formed.

[0074] The first housing 110a and the second housing 110b respectively have a semi-cylindrical accommodation space 111, so the first housing 110a and the second housing 110b can be assembled with each other to form a complete accommodation space 111. The first housing 110a and the second housing 110b can respectively have a plurality of engaging portions 112, such as engaging portions, bolt holes, etc., which are conventional engaging methods in the art, so as to be assembled with each other to form a complete housing 110. In addition, since the way the housing 110 is divided into the first housing 110a and the second housing 110b can be changed, for example, it can be divided vertically, horizontally, or obliquely, any structural features of the housing 110 described in this application can be provided in either the first housing 110a or the second housing 110b.

[0075] The outer surface of the housing 110 is generally square and has a first end wall 113 and a second end wall 114 that are longitudinally opposite. The accommodation space 111 is cylindrical and extends longitudinally. However, this is not necessary. In other embodiments, the outer surface of the housing 110 can be cylindrical, hexagonal prism-shaped, etc., and the accommodation space 111 can be square, hexagonal prism-shaped, etc. A plurality of limiting portions 115 extending longitudinally are provided on the outer side surface of the first end wall 113 to limit the lateral floating range, vertical floating range, and tilting floating range of the pipeline 120 relative to the housing 110. For example, the limiting portions 115 can abut against the periphery of the gasket 140 sleeved thereon, and the gasket 140 is sleeved on the outside of the pipeline 120. Therefore, the limiting portions 115 can limit the lateral floating range, vertical floating range, and tilting floating range of the pipeline 120.

[0076] A plurality of second spring grooves 116 are provided on the inner wall of the housing 110 (i.e., the outer side surface of the accommodation space 111). Each second spring groove 116 is recessed into the housing 110 horizontally or vertically to accommodate the second spring 192 respectively.

[0077] In other embodiments, the second floating spring 192 can be arranged in different forms, such as a flexible substance or liquid filled inside the housing 110.

[0078] A recessed portion 117 is provided on the outer surface of the housing 110, and the base 160 is arranged in the recessed portion 117. Specifically, the recessed portion 117 is arranged to be recessed into the housing 110 horizontally and vertically and extends longitudinally between the first end wall 113 and the second end wall 114. Therefore, the recessed portion 117 forms a groove that can accommodate the base 160 and allows the housing 110 to slide longitudinally relative to the base 160. The housing 110 is also provided with a plurality of holes 118, which are, for example, arranged on the side wall of the recessed portion 117. With reference to Figure 2 a plurality of pins 193 are inserted into the holes 118 for fixing to the housing 110. These pins 193 are inserted into the sliding grooves 163 of the base to guide the longitudinal sliding of the housing 110 relative to the base 160.

[0079] With reference to Figure 6 Describe the specific structure of the pipeline 120.

[0080] The pipeline 120 includes a first end 121, a second end 122, and an intermediate section 123 connected between the first end 121 and the second end 122. Both the first end 121 and the second end 122 are located outside the housing 110, and the intermediate section 123 is located inside the housing 110. A first flange 124 is provided between the first end 121 and the intermediate section 123, and a second flange 125 is provided between the second end 122 and the intermediate section 123. The first flange 124 and the second flange 125 are respectively located outside the longitudinal two ends of the housing 110. With reference to Figure 9B, a gasket 140 is provided between the first flange 124 and the first side wall 113 of the housing, and a gasket 140 and a snap ring 150 are provided between the second flange 125 and the second side wall 114 of the housing 110. Thus, the pipe 120 is substantially prevented from moving longitudinally relative to the housing 110, so that the pipe 120 and the housing 110 float longitudinally together. With reference to Figure 1F , the first flange portion 124 may be provided with at least one alignment portion 124a. For example, an alignment portion 124a in the form of a threaded hole is provided on the side of the first flange portion 124 facing away from the housing 110. The alignment portion 124a may be connected to a guide rod (not shown) to facilitate the alignment of the pipe 120 with the second object.

[0081] In use, the first end 121 of the pipe 120 is connected to a joint (not shown) of the second object, and the second end 122 is connected to a fluid pipe (not shown). Thus, a fluid such as coolant is introduced into the second object. The connection between the first end 121 and the second object may be a longitudinal plug-in connection. The connector 100 of the present application provides a longitudinal pressure feedback function to ensure a stable connection, where the meaning of a stable connection is that the longitudinal pressure between the first end 121 and the second object exceeds a threshold value. That is, when the first end 121 is not connected to the second object, or the longitudinal pressure between the first end 121 and the second object does not exceed the threshold value, the housing 110 (and the pipe 120) is in the second floating position, thus indicating that there is no stable connection. When the longitudinal pressure between the first end 121 and the second object exceeds the threshold value, the housing 110 (and the pipe 120) floats longitudinally relative to the base 160 and leaves the second floating position, thus indicating a stable connection. For this purpose, the biasing force of the first floating spring 191 may be set according to the pressure threshold, for example, set to be approximately equal to the pressure threshold, so that when the longitudinal pressure between the first end 121 of the pipe 120 and the second object exceeds the pressure threshold, the pipe 120 and the housing 110 can resist the biasing force of the first floating spring 191 under the action of the longitudinal pressure and leave the second floating position.

[0082] When the pipe 120 and the housing 110 leave the second floating position, the indicator 170 may provide an indication signal to indicate that the longitudinal pressure exceeds the threshold value. The indicator 170 will be described in detail below.

[0083] In other embodiments, the second end 122 of the pipe 120 is connected to the second object, and the first end 121 is connected to the fluid pipe. Or, in other embodiments, the first end 121 and the second end 122 of the pipe 120 are respectively connected to the joint of the second object and the joint of the third object, where the third object is a bracket or a plate fixed to the first object or the second object, etc. Thus, the connector 100 can accommodate the tolerances between the first object, the second object, and the third object.

[0084] With reference toFigure 7 Describe the specific structure of the base 160. The base 160 includes a pair of sliding portions 161 and a bridge portion 162 connected between the sliding portions 161. The sliding portions 161 are generally rectangular, and each sliding portion 161 is provided with a first spring groove 164 for accommodating the first floating spring 191. The first spring groove 164 extends longitudinally, one end of which is open at the outer side surface of the sliding portion 161, and the other end is enclosed in the sliding portion 161. Therefore, the first spring groove 164 is formed in the form of a blind hole. With reference to Figure 10 , one end of the first floating spring 191 extends to the outside of the sliding portion 161 and abuts against the first end wall 113 of the housing 110, and the other end abuts against the first spring groove 164.

[0085] Each sliding portion 161 is provided with a sliding groove 163 extending longitudinally. As described above, the pin 193 fixed to the housing 110 is inserted into the sliding groove 163 to guide the longitudinal floating of the housing 110 relative to the sliding portion 161. In this embodiment, each sliding portion 161 is provided with two longitudinally opposite sliding grooves 163, and the two pins 193 are respectively inserted into the two sliding grooves 163, thereby more stably guiding the longitudinal floating of the housing 110.

[0086] With reference to Figure 2 , the sliding portions 161 are arranged on both sides of the housing 110 in the transverse direction, and the bridge portion 163 is arranged on the bottom side of the housing 110. The sliding portions 161 and the bridge portion 162 do not extend beyond the extension range of the housing 110 in a plane perpendicular to the longitudinal direction. In this embodiment, the two sliding portions 161 and the bridge portion 163 of the base 160 form a three-sided surrounding frame and are embedded in the corresponding-shaped recessed portion 117 of the housing 110 (that is, the shape of the recessed portion 117 is a three-sided surrounding recess), so as to effectively utilize the gap between the square outer surface of the housing 110 and the cylindrical accommodating space 111. In other embodiments, the base 160 may have different shapes, such as being integrally flat as long as it can be fixedly arranged on the first object and allow the longitudinal floating of the housing 110 relative to the base 160.

[0087] Refer to Figure 8 Describe the indicator 170.

[0088] Generally, the indicator 170 is disposed on the base 160 and is configured to emit a signal when the housing 110 disengages from the second longitudinal position. As described above, when the pipe 120 is not connected to the second object, or when the pipe 120 is connected to the second object but does not generate a longitudinal pressure exceeding the threshold, the housing 110 is in the second longitudinal position. Therefore, when the housing 110 disengages from the second longitudinal position, it indicates that a longitudinal pressure exceeding the threshold has been generated between the housing 110 (and the pipe 120) and the second object. That is, the function of the indicator 170 is to indicate that a significant longitudinal float has occurred in the housing 110, which also means that the pipe 120 has been stably connected to the second object.

[0089] Specifically, the indicator 170 includes a plate portion 171, a switch 172, and a signal line 173. The plate portion 171 is in the shape of a square plate and is received in the bridge portion 162 of the base 160. More specifically, the plate portion 171 is embedded in the side of the bridge portion 162 facing away from the housing 110 to reduce the overall volume of the connector 100.

[0090] The switch 172 can be switched between a non-triggered state and a triggered state, and can be configured to send an indication signal in the non-triggered state. For example, in the triggered state, the switch 172 retracts into the plate portion 171, and in the non-triggered state, the switch 172 protrudes from the plate portion 171 and sends an indication signal. When the housing 110 is in the second longitudinal position, the second end wall 114 of the housing 110 abuts against the switch 172 to keep the switch 172 in the triggered state. More specifically, with reference to Figure 3B , at this time, the housing 110 is in the first longitudinal position, that is, it has disengaged from the second longitudinal position. At this time, the switch 172 is in the non-triggered state and protrudes from the plate portion 171 in the direction towards the second end wall 114. A spring (not shown) is provided in the plate portion 171 to bias the switch 172 in the protruding direction. At this time, the indicator 170 outputs an indication signal through the signal line 173 to indicate that the housing 110 has disengaged from the second longitudinal position, that is, a longitudinal pressure exceeding the threshold has been generated.

[0091] Refer to Figure 4B , at this time, the housing 110 is in the second longitudinal position, and the second end wall 114 abuts against the base 160, causing the switch 172 of the indicator 170 to be in the triggered state, that is, to retract into the plate portion 171. Therefore, the indicator 170 does not emit an indication signal.

[0092] It should be understood that when the housing 110 is displaced a certain distance from the second longitudinal position (this distance may be referred to as the "switch stroke"), the switch 172 can protrude from the plate portion 171. The switch stroke can be less than the distance between the first longitudinal position and the second longitudinal position. Therefore, when the distance between the second end wall 114 of the housing 110 and the base 160 exceeds the switch stroke, the switch 172 switches from the triggered state to the non-triggered state and sends an indication signal. The function of the first end wall 113 of the housing 110 can be to limit the longitudinal movement range of the housing 110 relative to the base 160.

[0093] In addition, as described above, during the process of establishing a connection between the second end 121 of the pipe 120 and the second object, the housing 110 is displaced from the second longitudinal position to indicate that a longitudinal pressure exceeding the threshold has been generated between the housing 110 and the second object. After the second end 121 is connected to the second object, depending on the type of the connection, the housing 110 can remain displaced from the second longitudinal position or return to the second longitudinal position under the action of the first floating spring 191. For example, if the second end 121 is inserted into the second object by a friction fit, after the connection is established, the second end 121 and the second object can move relative to each other, thereby allowing the housing to return to the second longitudinal position.

[0094] The plate portion 171 is provided with a groove so that the signal line 173 can extend from the switch 172 to the outside. In other embodiments, the indication signal can be sent wirelessly, so the signal line 173 can be omitted.

[0095] The specific structure of the indicator 170 in this embodiment can advantageously reduce the overall size of the connector 100 and transmit an easily acceptable electrical signal. In other embodiments, the indicator 170 can have different structures as long as it can transmit a signal according to the positional change between the base 160 and the housing 110.

[0096] Refer to Figure 9A and Figure 9B The relationship between the components of the connector 100 of the present application can be seen, especially the positional relationship among the housing 110, the pipe 120, and the second floating spring 192.

[0097] Refer to Figure 10 The relationship between the components of the connector 100 of the present application can be seen, especially the positional relationship among the base 160, the housing 110, and the first floating spring 191.

[0098] Although the preferred embodiments have been shown and described herein, it should be understood that these embodiments are given by way of example only.
