[0001] This application relates to the technical field of electrical equipment, and particularly to a housing and a power module. Background Art

[0002] Server power supplies are mainly used to supply power to IT devices such as servers, storage devices, and switches. The DC input of the server power supply is achieved by plugging the plug of the external power cord into the socket of the server power supply, and the whole server power supply is inserted into the equipment chassis to access the server system.

[0003] Before inserting or removing the server power supply from the chassis, it is necessary to first unplug the plug of the external power cord from the socket of the server power supply to avoid impacting the server power supply circuit when plugging or unplugging the server power supply under live conditions. Existing server power supplies remind users by pasting a no hot plugging label on the housing. However, the situation where the user fails to notice the label prompt content and the server power supply is damaged due to hot plugging the service power supply still occurs frequently. Summary of the Utility Model

[0004] In view of the problems existing in the background art, the purpose of this application is to provide a housing and a power module, which can reduce the occurrence of damage to the power module caused by the operator removing the power module from the chassis before unplugging the plug from the socket.

[0005] According to the first aspect of this application, a housing is provided, which includes a housing body, a locking assembly, and a limiting member. The housing body is used to be installed in the installation slot of the equipment.

The first end of the dial protrudes from the first wall, and the second end of the dial is fixedly connected to the housing body inside the housing body. Wherein, when the dial is toggled in the direction of the receiving space from the first end of the dial to the unlocking position, the housing body and the equipment are unlocked. The limiting member is arranged on the side of the dial facing the receiving space, and the end of the limiting member away from the dial is used to abut against the outer wall of the plug to block the dial from moving to the unlocking position.

[0006] In one or more of the above optional embodiments, the end of the limiting member away from the dial is used to insert into the assembly gap between the plug and the socket to abut against the outer wall of the plug within the assembly gap.

[0007] In one or more of the above optional embodiments, the locking component includes a clamping protrusion, and the clamping protrusion is disposed on a side of the paddle facing away from the accommodating space. Wherein, when the housing is mounted in the mounting groove, the clamping protrusion is clamped to the device to lock the housing to the device; when the first end of the paddle is toggled in the direction of the accommodating space to the unlocking position, the clamping protrusion is driven to separate from the device to unlock the housing.

[0008] In one or more of the above optional embodiments, the housing includes a second wall, and the second wall is provided with a through hole through which the clamping protrusion can extend out of the housing. Wherein, when the housing is locked to the device, the clamping protrusion passes through the through hole and is clamped to the device outside the housing; when the first end of the paddle is toggled to the unlocking position, the clamping protrusion moves relative to the through hole and disengages from the device to unlock the housing.

[0009] In one or more of the above optional embodiments, the limiting member includes a first half-ring and a second half-ring connected to each other, and an included angle is formed between the first half-ring and the second half-ring. The first half-ring abuts against the paddle along the axial direction of the first half-ring, and one end of the second half-ring away from the first half-ring is used to radially abut against the outer surface of the plug.

[0010] In one or more of the above optional embodiments, the outer shell further includes a gland, and the gland covers the surface of the first half-ring facing away from the paddle. When the second half-ring abuts against the outer surface of the plug, the included angle between the first half-ring and the second half-ring becomes smaller, driving the first half-ring to displace relative to the gland.

[0011] In one or more of the above optional embodiments, the gland includes a pressing plate, a first limiting portion and a second limiting portion. The pressing plate covers the surface of the first half-ring facing away from the paddle. The first limiting portion and the second limiting portion are connected to the pressing plate. The first limiting portion and the second limiting portion are respectively located on both sides of the first half-ring. Opposite sides of the first half-ring respectively abut against the first limiting portion and the second limiting portion, and the first half-ring slides relative to the gland between the first limiting portion and the second limiting portion.

[0012] In one or more of the above optional embodiments, along the direction from the second end to the first end of the paddle, the distance between the first limiting portion and the second limiting portion gradually decreases.

One end of the first abutting section is connected to one end of the second abutting end and is distributed at an angle. The other end of the first abutting section abuts against the first limiting portion, and the other end of the second abutting section abuts against the second limiting portion. When the first half-ring moves towards the first end of the paddle, the first limiting portion and the second limiting portion respectively act on the first abutting section and the second abutting section to drive the first abutting section and the second abutting section to deform.

[0013] In one or more of the above optional embodiments, the housing further includes a nut and a bolt. One end of the nut is fixed to the gland, the other end of the nut is located between the gland and the paddle, the nut passes through the first half-ring, and the bolt passes through the first end of the paddle and is screwed and fixed to the nut to fix the gland to the paddle.

[0014] In one or more of the above optional embodiments, the limiting member is formed by bending an elastic wire and generates an elastic force to return to its original shape after being deformed by force.

[0015] According to a second aspect of the present application, there is provided a power module including the housing as described above. The beneficial effects of the embodiments of the present application are as follows: The housing provided by the embodiments of the present application, by providing a limiting member at the first end of the paddle, the limiting member is used to prevent the paddle from moving to the unlocking position by abutting against the outer wall of the plug when the plug is inserted into the socket. When the housing provided by the embodiments of the present application is applied to the power module, when the limiting member can abut against the plug to prevent the paddle from moving to the unlocking position, after the operator pulls out the plug from the socket to cut off the power of the power module, the paddle can be toggled to unlock the housing and the plug frame, and then the power module can be taken out of the plug frame. In the above manner, the housing provided by the embodiments of the present application can reduce the situation that the operator takes out the power module from the plug frame before pulling out the plug from the socket, resulting in damage to the power module.

[0033] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0034] Please refer to Figure 1 , the housing 100 includes a housing body 1 and a locking assembly 2. The housing 100 is used to be installed in the installation slot of the device. The locking assembly 2 is connected to the housing body 1. The locking assembly 2 is used to lock the housing body 1 with the device when the housing body 1 is installed in the installation slot to prevent the housing body 1 from being taken out of the installation slot, and to allow the housing body 1 to be taken out of the installation slot when in the unlocked state.

[0035] Please refer to Figure 1 and Figure 2 , in some embodiments, a socket 200 is installed on the first wall 12 of the housing body 1, and a receiving space 122 is provided outside the first wall 12. The plug is inserted and matched with the socket 200 in the receiving space 122.

[0036] Please refer to Figure 2 and Figure 3In some embodiments, the housing 1 is provided with a receiving cavity 11, the receiving cavity 11 is located on the inner side of the first wall 12, the first wall 12 of the housing 1 is provided with an installation opening 121, the installation opening 121 is communicated with the receiving cavity 11, and the socket 200 is installed in the installation opening 121; please refer to Figure 1 and Figure 6 In some embodiments, the locking assembly 2 includes a paddle 21, a first end 211 of the paddle 21 protrudes from the first wall 12, and a second end 212 of the paddle 21 extends into the accommodating cavity 11 and is connected to the housing 1. When the first end 211 of the paddle 21 is moved in the direction b of the accommodating space 122 until the paddle 21 moves to the unlocking position, the locking assembly 2 is in the unlocking state, and the housing 1 is unlocked from the device. Figures 4 - 8 In some embodiments, the housing 100 includes a stopper 3, which is disposed on the side of the paddle 21 facing the accommodation space 122, and an end of the stopper 3 away from the paddle 21 is used to abut against the outer wall of the plug 300 to prevent the paddle 21 from moving to the unlocked position. When the socket 200 is plugged with the plug 300, the plug 300 is located in the accommodation space 122. Figure 8 As shown, at this time, the paddle 21 is moved along the first end 211 of the paddle 21 in the direction b of the accommodation space 122, and the stopper 3 arranged at the paddle 21 abuts against the outer wall of the plug 300 to prevent the paddle 21 from moving to the unlocking position, the locking assembly 2 cannot be unlocked, and the housing 1 cannot be removed from the installation groove; when the plug 300 is pulled out of the socket 200, as shown in FIG. Figure 4 As shown, at this time, there is no plug 300 blocking the limiter 3 in the accommodation space 122, and the limiter 3 can move to the unlocking position together with the paddle 21, thereby unlocking the housing 1 and the device, and the housing 1 can be taken out from the installation slot. Taking the application of the housing 100 to the power module 1000 as an example, a socket 200 for plugging the plug 300 is installed at the installation port 121. When in use, the housing 100 is inserted into the installation slot of the plug frame, the locking component 2 locks the power module 1000 in the plug frame, and the plug 300 is inserted into the socket 200, and the power supply supplies power to the power module 1000 through the plug 300 connected to the power cord. Since the paddle 21 is provided with a limiting member 3, when the plug 300 is plugged into the socket 200 and the power module 1000 is in a powered state, the limiting member 3 can abut against the plug 300 to prevent the paddle 21 from moving to the unlocked position. Therefore, the power module 1000 cannot be pulled out of the installation slot of the plug frame at this time. The operator can only pull the plug 300 out of the socket 200 to cut off the power of the power module 1000, and then move the paddle 21 to unlock the shell 1 and the plug frame, and then remove the power module 1000 from the plug frame. In the above manner, the housing 100 provided in the embodiment of the present application can reduce the situation where the operator removes the power module 1000 from the plug frame before pulling the plug 300 out of the socket 200, resulting in damage to the power module 1000. Please refer toFigure 2 and Figure 3 In some embodiments, the first wall 12 is provided with an avoidance hole 124, which is communicated with the accommodating cavity 11, and the second end 212 of the paddle 21 is located in the accommodating cavity 11. The paddle 21 passes through the avoidance hole 124, and the avoidance hole 124 is used to provide a movable space for the first end 211 of the paddle 21, so that the paddle 21 can move to an unlocked position relative to the shell 1.

[0037] See also Figure 1 and Figure 4 In some embodiments, the locking assembly 2 includes a snap-on protrusion 22, which is disposed on a side of the paddle 21 facing away from the accommodating space 122. When the housing 1 is installed in the mounting slot, the snap-on protrusion 22 is snapped on the device to lock the housing 1 to the device. Figure 4 As shown, when the first end of the paddle 21 is pushed along the direction b of the first end 211 of the paddle toward the accommodating space 122 to the unlocking position, the engaging protrusion 22 is driven to separate from the device to unlock the housing 1 .

[0038] In some embodiments, the first end of the paddle 21 is bent toward the receiving space 122 relative to the second end 212 of the paddle 21 to drive the engaging protrusion 22 to separate from the device. In some embodiments, the housing 1 is used to be inserted into the mounting slot of the device along the receiving space 122 toward the receiving cavity 11 in the direction c.

[0039] In some embodiments, when the housing 1 is installed in the mounting slot, the snap-fitting protrusion 22 is snap-fitted to the snap-fitting hole of the device set on the inner wall of the mounting slot. It is understandable that the matching structure between the device and the snap-fitting protrusion 22 can be set according to the actual use situation, for example, the snap-fitting protrusion 22 can also be snap-fitted to the snap-fitting slot of the device, or in the embodiment where the housing 1 can only be taken out of the mounting slot along a certain preset direction, the snap-fitting protrusion 22 can also be snap-fitted to the limit stop set by the device in the preset direction to prevent the housing 1 from moving along the preset direction.

[0040] In some embodiments, the first wall 12 is provided with a handle 123 , and the handle 123 is used to pull the housing 1 out of the installation groove along the direction a from the accommodating cavity 11 to the accommodating space 122 .

[0041] See also Figures 1 - 4 In some embodiments, the housing 1 includes a second wall 13, and the second wall 13 is provided with a through hole 131, through which the snap-on protrusion 22 can extend out of the housing 1. When the housing 1 is locked with the device, the snap-on protrusion 22 passes through the through hole 131 and snaps onto the device outside the housing 1. When the first end 211 of the paddle 21 is moved to the unlocking position, the snap-on protrusion 22 moves relative to the through hole 131 and disengages from the device to unlock the housing 1.

[0042] In some embodiments, after the first end 211 of the paddle 21 is bent relative to the second end 212 of the paddle 21 towards the accommodation space 122, the engaging protrusion 22 can be driven to retract into the accommodation cavity 11 through the through hole 131. In some embodiments, the second end 212 of the paddle 21 is riveted and fixed to the second wall 13.

[0043] In some embodiments, the shape of the housing 1 matches the shape of the installation groove. When the housing 1 is installed in the installation groove, the inner wall of the installation groove limits the housing 1.

[0044] In some embodiments, the housing 1 is generally rectangular. The housing 1 includes a third wall 14 disposed opposite to the first wall 12 along the direction c from the accommodation space 122 towards the accommodation cavity 11, a fourth wall 15 disposed opposite to the second wall 13 along the direction b from the first end 211 of the paddle 21 towards the accommodation space 122, a fifth wall 16 and a sixth wall 17 disposed opposite to each other along the direction d. The first wall 12, the second wall 13, the third wall 14, the fourth wall 15, the fifth wall 16 and the sixth wall 17 jointly enclose the accommodation cavity 11. Among them, the direction c from the accommodation space 122 towards the accommodation cavity 11, the direction b from the first end 211 of the paddle 21 towards the accommodation space 122 and the direction d are perpendicular to each other in pairs.

[0045] In some embodiments, the paddle 21 is configured such that the first end 211 of the paddle 21 can be elastically bent relative to the second end 212 of the paddle 21 towards the accommodation space 122 and then move to the unlocking position. When the external force is removed, the first end 211 of the paddle 21 can automatically reset to the initial position or reset to a position close to the initial position.

[0046] In some embodiments, the paddle 21 is made of a metal material.

[0047] In some embodiments, the paddle 21 includes, but is not limited to, a spring steel sheet.

[0048] In some embodiments, the engaging protrusion 22 is disposed on the side of the paddle 21 facing the second wall 13. When the first end 211 of the paddle 21 is in the initial position, at least a part of the engaging protrusion 22 passes through the through hole 131 and protrudes from the surface of the second wall 13 facing away from the accommodation cavity 11. When the housing 1 is inserted into the installation groove along the direction c from the accommodation space 122 towards the accommodation cavity 11, the engaging protrusion 22 protruding from the surface of the second wall 13 facing away from the accommodation cavity 11 abuts against the inner wall surface of the installation groove and retracts into the through hole 131 under the action of the inner wall surface of the installation groove. At this time, the engaging protrusion 22 pushes the paddle to elastically bend. When the housing 1 moves to align the engaging protrusion 22 with the engaging hole, the paddle 21 elastically resets so that the engaging protrusion 22 protrudes from the through hole 131 again to engage with the engaging hole.

[0049] Please refer to Figure 9In some embodiments, the height of the clamping protrusion 22 gradually decreases along the direction c from the accommodating space 122 to the accommodating cavity 11, so as to form an inclined surface 221a at the end of the clamping protrusion 22 away from the paddle 21. The inclined surface 221a is used to abut against the inner wall surface of the mounting groove when the housing 1 is inserted into the mounting groove along the direction c from the accommodating space 122 to the accommodating cavity 11. The inclined surface 221a can guide the housing 1 to be smoothly inserted into the mounting groove, reduce the resistance and friction during the plugging, and make the plugging process smoother.

[0050] In some embodiments, the number of the clamping protrusions 22 is two, and the two clamping protrusions 22 are arranged side by side and spaced apart along the direction d.

[0051] In some embodiments, the first end 211 of the paddle 21 is sleeved with a paddle cover 23 , and the paddle cover 23 is used for an operator to press or grasp.

[0052] In other embodiments, different from the above embodiments, the paddle 21 does not move to the unlocking position in a bending and deforming manner, and the locking assembly 2 includes a base, which is fixed to the housing 1, and the paddle 21 is slidably disposed on the base along a direction b parallel to the first end 211 of the paddle toward the accommodating space 122. When the paddle 21 is moved along the first end 211 of the paddle toward the direction b of the accommodating space 122, the paddle 21 slides along the first end 211 of the paddle toward the direction b of the accommodating space 122 to the unlocking position, thereby driving the engaging protrusion 22 to disengage from the engaging protrusion 22, so that the housing 1 is unlocked from the device.

[0053] See also Figures 5 - 8 In some embodiments, the end of the stopper 3 away from the paddle 21 is used to be inserted into the assembly gap G between the plug 300 and the socket 200, so as to abut against the outer wall of the plug 300 in the assembly gap G. In some plugs 300 and sockets 200 currently used in the market, a protrusion is provided on the outer peripheral wall of the plug 300. When the plug 300 is plugged into the socket 200, an assembly gap G is formed between the end surface of the socket 200 facing the plug 300 and the surface of the protrusion facing the socket 200. For example, in a standard IEC60320 issued by the International Electrotechnical Commission (IEC), after the sockets 200 of models C14, C16, and C20 are plugged into the corresponding plugs 300 of models C13, C15, and C19, an assembly gap G of 1 mm is formed along the direction in which the plug 300 is plugged into the socket 200. By configuring the end of the limit member 3 away from the paddle 21 to be inserted into the assembly gap G and abut against the outer wall of the plug 300 in the assembly gap G, the end face of the socket 200 facing the plug 300 and the surface of the protrusion facing the socket 200 can be used to limit the limit member 3, thereby reducing the problem of failure of the limit member 3 caused by the end of the limit member 3 abutting against the outer wall of the plug 300 sliding relative to the outer wall of the plug 300.

[0054] See also Figure 7 , Figure 8 and Figure 12 In some embodiments, the stopper 3 includes a first half ring 31 and a second half ring 32 connected to each other, and the first half ring 31 and the second half ring 32 are arranged at an angle. The first half ring 31 abuts against the paddle 21 along the axial direction of the first half ring 31, and the end of the second half ring 32 away from the first half ring 31 is used to abut against the outer surface of the plug 300 along the radial direction of the second half ring 32. When the paddle 21 is moved along the first end 211 of the paddle toward the direction b of the accommodation space 122 so that the end of the second half ring 32 away from the first half ring 31 abuts against the outer wall of the plug 300, the connection between the first half ring 31 and the second half ring 32 can be subjected to force to produce elastic deformation, so that the preset angle α is reduced. When one end of the second half ring 32 away from the first half ring 31 abuts against the outer wall of the plug 300, the first half ring 31 is pushed by the first end 211 of the paddle 21, and elastic deformation occurs at the connection between the first half ring 31 and the second half ring 32, so that the angle α between the first half ring 31 and the second half ring 32 is reduced, thereby playing a buffering role and reducing impact force, which is beneficial to protecting the plug 300 and the paddle 21 and extending the service life of the plug 300 and the paddle 21.

[0055] In some embodiments, the limiting member 3 is made of elastic material.

[0056] In some embodiments, the limiting member 3 is formed by bending an elastic steel wire, and generates elastic force to restore the original shape after being deformed by force.

[0057] In some embodiments, when the first end 211 of the paddle 21 is not acted upon by an external force, the angle α between the first half ring 31 and the second half ring 32 is 90°.

[0058] See also Figure 8 and Figure 12 In some embodiments, the housing 100 further includes a pressure cover 4, which is disposed on a surface of the first half ring 31 that faces away from the paddle 21. The pressure cover 4 and the first end 211 of the paddle 21 clamp the first half ring 31 together.

[0059] In some embodiments, when the second half ring 32 abuts against the outer surface of the plug 300 , the angle α between the first half ring 31 and the second half ring 32 becomes smaller to drive the first half ring 31 to move relative to the gland 4 .

[0060] See also Figures 9 - 13 In some embodiments, the housing 100 further includes a nut 5 and a bolt 6, one end of the nut 5 is fixed to the gland 4, the other end of the nut 5 is located between the gland 4 and the paddle 21, the nut 5 is passed through the first half ring 31, and the bolt 6 passes through the first end 211 of the paddle 21 and is screwed and fixed to the nut 5 to fix the gland 4 to the paddle 21.

[0061] In some embodiments, the pressure cover 4 includes a pressure plate 41, a first limiting portion 42 and a second limiting portion 43. The pressure plate 41 is covered on the surface of the first half ring 31 facing away from the paddle 21. The first limiting portion 42 and the second limiting portion 43 are connected to the pressure plate. The first limiting portion 42 and the second limiting portion 43 are respectively located on both sides of the first half ring 31. The opposite sides of the first half ring 31 respectively support the first limiting portion 42 and the second limiting portion 43. The first half ring 31 slides relative to the pressure cover 4 between the first limiting portion 42 and the second limiting portion 42.

[0062] In some embodiments, the spacing S between the first limiting portion 42 and the second limiting portion 43 gradually decreases along the direction from the second end 212 to the first end 211 of the paddle 21. In some embodiments, the first limiting portion 42 is obtained by bending an edge of one side of the pressing plate 41 toward the paddle 21 and then extending, and the second limiting portion 43 is obtained by bending an edge of the other side of the pressing plate 41 toward the paddle 21 and then extending.

[0063] In some embodiments, the first half ring 31 includes a first abutting section 311 and a second abutting section 312 that are arranged opposite to each other, one end of the first abutting section 311 is connected to one end of the second abutting section 312 and is distributed at an included angle, the other end of the first abutting section 311 abuts against the first limiting portion 42, and one end of the second abutting section 312 away from the first abutting section 311 abuts against the second limiting portion 43. When the first half ring 31 moves toward the first end 211 of the paddle 21, the first limiting portion 42 and the second limiting portion 43 act on the first abutting section 311 and the second abutting section 312 respectively to drive the first abutting section 311 and the second abutting section 312 to deform. When the paddle 21 is moved in the direction b from the first end 211 of the paddle 21 to the accommodating space 122 so that the end of the second half ring 32 away from the first half ring 31 abuts against the outer wall of the plug 300, and the connection between the first half ring 31 and the second half ring 32 is elastically deformed to reduce the angle α, the first half ring 31 slides toward the first end 211 of the paddle 21, and the first limiting portion 42 and the second limiting portion 43 apply pressure to the first abutting section 311 and the second abutting section 312 respectively, so that the end of the first abutting section 311 away from the second abutting end and the end of the second abutting section 312 away from the first abutting section 311 move toward each other, and the angle β between the first abutting section 311 and the second abutting section 312 is reduced. The elastic deformation generated at the connection between the first abutting section 311 and the second abutting end can play a buffering role, reduce the impact force on the paddle 21 and the first half ring 31, and extend the service life of the paddle 21 and the limiting member 3.

[0064] In some embodiments, the second abutting section 312 is obtained by bending and extending one end of the first abutting section 311 , and an arc-shaped bending portion 313 is formed at the connection between the first abutting section 311 and the second abutting end.

[0065] In other embodiments, the difference from the above embodiments is that the limit member 3 is generally block-shaped, one end of the limit member 3 is fixed to the surface of the paddle 21 facing the accommodating space 122, and the other end of the limit member 3 is used to abut against the outer wall of the plug 300 outside the assembly gap G.

[0066] Furthermore, the limit member 3 is a silicone pad. On the one hand, the silicone pad has a certain elasticity. While satisfying the limiting function of preventing the paddle 21 from moving to the unlocking position, it can also play a buffering role, which is beneficial to protecting the plug 300 and the paddle 21 and extending the service life of the plug 300 and the paddle 21; on the other hand, the silicone surface usually has a higher friction coefficient, so that it can provide a greater friction force when contacting the outer wall of the plug 300, so as to reduce the problem of the limit member 3 slipping off the outer wall of the plug 300.

[0067] In some embodiments, the silicone pad is adhered and fixed to the surface of the first end 211 of the paddle 21 facing the receiving space 122 .
