Description

Technical Field

[0001] The present disclosure relates to the technical field of power supply, and in particular to a power supply module and a desktop power supply. Background Art

[0002] A power socket is an electrical device that provides a power interface for household appliances. It is also an electrical accessory that is used more frequently in residential electrical design. A power socket can power household appliances and small portable devices. A power socket has a slot for inserting a power plug with a rod-shaped or copper-shaped protrusion to conduct electricity to the appliance through the plug. It is an essential electrical accessory in life.

[0003] With the advancement and development of technology, desktop power supplies are becoming more and more popular due to their convenience of integrating multiple output interfaces. However, when the socket of the desktop power supply is not connected to the plug, it is easy to cause safety problems. Utility Model Content

[0004] Based on this, it is necessary to provide a power module and a desktop power supply.

[0005] The embodiment of the present disclosure provides a power module, which includes a shell and a socket assembly. The shell has an accommodating space and a plurality of jacks, the jacks penetrate the shell along a first direction, and the jacks are connected to the accommodating space. The socket assembly is located in the accommodating space, and the socket assembly includes a conductive strip, a first blocking member, a second blocking member, and an elastic connector. The conductive strip includes a plurality of plug-in structures, the plug-in structures correspond to the jacks, and the first blocking member and the second blocking member are respectively located between the corresponding plug-in structures and the jacks; the first blocking member is connected to the second blocking member through an elastic connector, and the elastic connector is used to drive the first blocking member and the second blocking member to move along the driving direction. The first blocking member has a first covering position and a first avoidance position relative to the shell along the driving direction, and the projection of the first blocking member in the first covering position along the first direction covers the plug-in structure. The second blocking member has a second covering position and a second avoidance position relative to the shell along the driving direction, and the projection of the second blocking member in the second covering position along the first direction covers the plug-in structure.

[0006] In the power module provided by the embodiment of the present disclosure, the first blocking member and the second blocking member are arranged corresponding to the jack of the shell. When the plug is not inserted, the first blocking member and the second blocking member cover the plug-in structure of the conductive strip, so that the conductive strip cannot be electrically connected to the outside world, and the jack is closed to avoid installation hazards. When the plug is inserted into the jack, the sealing parts of the first blocking member and the second blocking member can change their positions under the action of external force, exposing the plug-in structure so that the plug can enter the interior of the socket assembly and turn on the power. After the plug is pulled out, due to the elasticity of the elastic connector, the first blocking member returns to the first covering position and the second blocking member returns to the second covering position, thereby covering the corresponding plug-in structure of the conductive strip to cut off the power, thereby reducing the safety hazards when the power module is not in use.

[0007] The power module provided in the embodiment of the present disclosure uses an elastic connector to reset the first blocking member and the second blocking member, has a simple structure, a fast reset speed and can accurately cover the plug-in structure, thereby improving the reset flexibility and accuracy.

[0008] In some of the embodiments, the plurality of jacks include a double jack and a triple jack, the triple jack includes a single jack and two inclined jacks, and the single jack is located between the two jacks of the double jack.

[0009] The projection of the first blocking member in the first covering position along the first direction covers the plug-in structures corresponding to the double plug-ins; the projection of the second blocking member in the second covering position along the first direction covers the plug-in structures corresponding to the two inclined plug-ins.

[0010] In this way, the first blocking piece can cover or expose the plug-in structure corresponding to the double jack, and the second blocking piece can cover or expose the plug-in structure corresponding to the two inclined jacks, which facilitates the use of the double jack and the triple jack separately or simultaneously, and reduces the safety hazard when the power module is not in use.

[0011] In some embodiments, the first blocking part includes a first supporting portion and two first blocking portions, the first supporting portion surrounds the double hole and the single hole, and the two first blocking portions are connected to the first supporting portion; the projections of the two first blocking portions in the first covering position along the first direction respectively cover the plug-in structures corresponding to the double holes.

[0012] The second blocking part includes a second supporting part and two second blocking parts. The second supporting part surrounds two inclined sockets. The two second blocking parts are obliquely connected to the second supporting part. The projections of the two second blocking parts in the second covering position along the first direction respectively cover the plug-in structures corresponding to the two inclined sockets.

[0013] With such arrangement, the first supporting part facilitates supporting the first blocking part, and the second supporting part facilitates supporting the first blocking part, thereby facilitating the overall movement of the first blocking member and the second blocking member and the accuracy of covering the plug-in structure.

[0014] In some embodiments, the first blocking portion and the second blocking portion each have an inclined surface facing the insertion hole and inclined relative to the first direction. The inclined surfaces of the two first blocking portions are inclined toward the same side; the inclined surfaces of the two second blocking portions are inclined toward the same side.

[0015] The provision of the inclined surface facilitates the first blocking member and the second blocking member to move along the first direction so as to expose the corresponding plug-in structure.

[0016] In some embodiments, a first connection portion is protruded on one side of the first support portion facing the second blocking member; a second connection portion is protruded on one side of the second support portion facing the first blocking member; the elastic connection member includes a first end and a second end that are oppositely arranged along the driving direction, the first end is connected to the first connection portion, and the second end is connected to the second connection portion. The elastic connection member is a spring.

[0017] This arrangement facilitates the elastic connector to produce elastic deformation under the action of external force. When the external force disappears, the elastic connector recovers its deformation along the driving direction to facilitate the reset of the first blocking member and the second blocking member, thereby improving the reset accuracy of the elastic connector.

[0018] In some embodiments, the first blocking member further includes a first reinforcing rib, the first reinforcing rib is connected to the first supporting portion, the first reinforcing rib is located between the two first blocking portions, and the projection of the first reinforcing rib along the first direction avoids the plug-in structure corresponding to the single plug-in hole;

[0019] The second blocking member further includes a second reinforcing rib, which is connected to the second supporting portion and is located between the two second blocking portions.

[0020] In this configuration, the first reinforcing rib is conducive to increasing the strength of the first blocking member, thereby reducing the deformation of the first blocking member. The second reinforcing rib is conducive to increasing the strength of the second blocking member, thereby reducing the deformation of the second blocking member.

[0021] In some embodiments, the socket assembly also includes a base, which is located on the side of the first blocking member and the second blocking member facing the conductive strip, the conductive strip, the first blocking member and the second blocking member are respectively connected to the base, and a plurality of limit members are protruding from the side of the base facing the shell, a part of the limit members are used to limit the first blocking member in a first avoidance position, and another part of the limit members are used to limit the second blocking member in a second avoidance position.

[0022] With such arrangement, the base plays a supporting role to prevent the position of the conductive strip from changing, and at the same time facilitates the limiting member to limit the moving position of the first blocking member and the second blocking member.

[0023] In some embodiments, the plurality of limit members include a first limit member, a second limit member and a third limit member, and the first limit member is located between the first reinforcing rib and the inclined surface of the first blocking portion;

[0024] The second stopper is located between the second reinforcing rib and the inclined surface of one second blocking portion; the third stopper is located on one side of the other second blocking portion having the inclined surface;

[0025] The first limiting member is used to limit the first blocking portion at the first avoidance position along the driving direction; the second limiting member and the third limiting member are used to limit the second blocking portion at the second avoidance position along the driving direction.

[0026] With this arrangement, the first limiter prevents the first blocking member from moving too far after being acted upon by an external force, thereby making it difficult to accurately reset the member. The second limiter and the third limiter prevent the second blocking member from moving too far after being acted upon by an external force, thereby making it difficult to accurately reset the member.

[0027] In some embodiments, the first blocking member has a first arc surface, the first arc surface is located on the first supporting portion, and the first arc surface abuts against the base.

[0028] The second blocking member has a second arc surface, the second arc surface is located at the second reinforcing rib, and the second arc surface abuts against the base.

[0029] The setting of the first arc surface and the second arc surface makes the first blocking member, the second blocking member and the base in line contact, which can reduce the resistance when the first blocking member and the second blocking member move, and facilitate the first blocking member and the second blocking member to cover or expose the corresponding plug-in structure.

[0030] The disclosed embodiment provides a desktop power supply, which includes the above-mentioned power module and a power line, wherein the power line is electrically connected to the conductive strip of the power module.

[0031] The desktop power supply provided in the embodiment of the present disclosure has a power cord that can input alternating current to the power module, and the provision of the first blocking member and the second blocking member reduces potential safety hazards when the desktop power supply is not in use.

[0044] A power socket has a slot for inserting a power plug with a rod-shaped or copper-shaped protrusion to transmit electricity to the electrical appliance through the plug. It is an essential electrical accessory in life. With the advancement and development of technology, desktop power supplies are becoming more and more popular due to their convenience of integrating multiple output interfaces. However, when the socket of a desktop power supply is not connected to the plug, it is easy to cause safety problems.

[0045] refer to Figure 1 , Figure 1 The disassembled structure of the power module in the embodiment of the present disclosure is shown. The embodiment of the present disclosure provides a power module 100, which includes a shell 10 and a socket assembly 20. The shell 10 has a housing space and a plurality of jacks 11. The jacks 11 penetrate the shell 10 along a first direction, and the jacks 11 are connected to the housing space. The socket assembly 20 is located in the housing space. The socket assembly 20 includes a conductive strip 21, a first blocking member 22, a second blocking member 23 and an elastic connector 24. The conductive strip 21 includes a plurality of plug-in structures 211, and the plug-in structures 211 correspond to the jacks 11. The first blocking member 22 and the second blocking member 23 are respectively located between the corresponding plug-in structures 211 and the jacks 11. Exemplarily, the first direction is the front-to-back direction.

[0046] The first blocking member 22 can move along the driving direction, and the second blocking member 23 can move along the driving direction. The elastic connecting member 24 is used to connect and drive the first blocking member 22 and the second blocking member 23 to move. Exemplarily, the driving direction is the left-right direction. The elastic action of the elastic connecting member 24 causes the first blocking member 22 to move to the left and the second blocking member 23 to move to the right.

[0047] The first blocking member 22 has a first covering position and a first avoiding position relative to the housing 10 along the driving direction, and the projection of the first blocking member 22 in the first covering position along the first direction covers the plug-in structure 211. The second blocking member 23 has a second covering position and a second avoiding position relative to the housing 10 along the driving direction, and the projection of the second blocking member 23 in the second covering position along the first direction covers the plug-in structure 211.

[0048] In the power module 100 provided in the embodiment of the present disclosure, when the plug is not inserted, the first blocking member 22 is located at the first covering position, and the second blocking member 23 is located at the second covering position, so that the conductive strip 21 cannot be electrically connected to the outside, and the jack 11 is closed to avoid installation hazards. After the plug is inserted, the elastic connector 24 is deformed due to the external force, and the first blocking member 22 moves to the first avoidance position, and the second blocking member 23 moves to the second avoidance position, thereby exposing the plug structure 211, allowing the plug to enter the interior of the socket assembly 20 to connect to the power supply. When the plug is pulled out, the elastic deformation recovery of the elastic connector 24 drives the first blocking member 22 back to the first covering position to cover the corresponding plug structure 211, and the second blocking member 23 returns to the second covering position to cover the corresponding plug structure 211, thereby playing the role of power off, reducing the safety hazard when the power module 100 is not in use.

[0049] The power module 100 provided in the embodiment of the present disclosure uses the elastic connecting member 24 to reset the first blocking member 22 and the second blocking member 23, which has a simple structure, a fast reset speed and can accurately cover the plug-in structure 211, thereby improving the reset flexibility and accuracy.

[0050] Exemplarily, the first blocking member 22 and the second blocking member 23 completely cover their corresponding plug-in structures 211 .

[0051] Exemplarily, the first blocking member 22 and the second blocking member 23 are arranged in the up-down direction. Both the first blocking member 22 and the second blocking member 23 can move in the left-right direction. The moving direction of the first blocking member 22 from the first covering position to the first avoidance position is to the left, and the moving direction of the second blocking member 23 from the second covering position to the second avoidance position is to the right. Exemplarily, when the plug is inserted into the socket 11 corresponding to the first blocking member 22, the first blocking member 22 moves to the right and the second blocking member 23 remains stationary. When the plug is pulled out, the elastic connecting member 24 elastically deforms and gradually stretches in the left-right direction, driving the first blocking member 22 to move to the left and return to its original position.

[0052] For example, when the plug is inserted into the jack 11 corresponding to the second blocking member 23, the second blocking member 23 moves to the left and remains stationary. When the plug is pulled out, the elastic connector 24 elastically deforms and gradually stretches in the left-right direction, driving the second blocking member 23 to move to the right and return to its original position.

[0053] For example, when the plug is inserted into the jack 11, the first blocking member 22 moves to the right and the second blocking member 23 moves to the left. The elastic connecting member 24 shortens in the left-right direction. When the plug is pulled out, the elastic connecting member 24 elastically deforms and gradually lengthens in the left-right direction, driving the first blocking member 22 to move to the left and the second blocking member 23 to move to the right, thereby returning to their original positions.

[0054] Exemplarily, the housing 10 is in the shape of a cuboid.

[0055] Exemplarily, one plug-in structure 211 corresponds to one plug hole 11 .

[0056] Exemplarily, the first blocking member 22 and the second blocking member 23 are both made of self-lubricating, flame-retardant plastic material, which facilitates the movement of the first blocking member 22 and the second blocking member 23 , and can cut off the power and is not prone to self-ignition, thereby increasing the safety performance of the power module 100 .

[0057] Exemplarily, the power module 100 includes a plurality of first blocking members 22 and second blocking members 23 , and the number of the first blocking members 22 and the number of the second blocking members 23 are equal.

[0058] refer to Figure 1 In some embodiments, the plurality of jacks 11 include a double jack 111 and a triple jack, the triple jack includes a single jack 112 and two inclined jacks 113 , and the single jack 112 is located between the two jacks 11 of the double jack 111 .

[0059] The projection of the first blocking member 22 in the first covering position along the first direction covers the plug-in structure 211 corresponding to the double plug holes 111 ; the projection of the second blocking member 23 in the second covering position along the first direction covers the plug-in structure 211 corresponding to the two inclined plug holes 113 .

[0060] In this way, the first blocking member 22 can cover or expose the plug structure 211 corresponding to the double jack 111, and the second blocking member 23 can cover or expose the plug structure 211 corresponding to the two inclined jacks 113. This facilitates the use of the double jack 111 and the three jacks separately or simultaneously, reducing the potential safety hazard when the power module 100 is not in use.

[0061] refer to Figure 2 In some embodiments, the first blocking member 22 includes a first supporting portion 221 and two first blocking portions 222, the first supporting portion 221 surrounds the double socket 111 and the single socket 112, and the two first blocking portions 222 are connected to the first supporting portion 221; the projections of the two first blocking members 22 in the first covering position along the first direction respectively cover the plug-in structures 211 corresponding to the double socket 111.

[0062] The second blocking member 23 includes a second supporting portion 231 and two second blocking portions 232. The second supporting portion 231 surrounds two inclined sockets 113. The two second blocking portions 232 are obliquely connected to the second supporting portion 231. The projections of the two second blocking members 23 in the second covering position along the first direction respectively cover the plug-in structures 211 corresponding to the two inclined sockets 113.

[0063] With such arrangement, the first supporting portion 221 facilitates supporting the first blocking portion 222 , and the second supporting portion 231 facilitates supporting the first blocking portion 222 , thereby facilitating the overall movement of the first blocking member 22 and the second blocking member 23 and ensuring the covering accuracy of the plug-in structure 211 .

[0064] Exemplarily, the first support portion 221 is arranged in a semi-enclosed structure around the double plug holes 111 and the single plug hole 112, and the two first blocking portions 222 are connected to the first support portion 221 along the up-down direction. The second support portion 231 is arranged in a semi-enclosed structure around the two inclined plug holes 113, and the two second blocking portions 232 are connected to the second support portion 231 along the up-down direction.

[0065] refer to Figure 2 In some embodiments, the first blocking portion 222 and the second blocking portion 232 each have an inclined surface facing the insertion hole 11 and inclined relative to the first direction. The inclined surfaces of the two first blocking portions 222 are inclined toward the same side; the inclined surfaces of the two second blocking portions 232 are inclined toward the same side.

[0066] The provision of the inclined surface facilitates the first blocking member 22 and the second blocking member 23 to move along the first direction so as to expose the corresponding plug-in structure 211 .

[0067] Exemplarily, the inclined surfaces of the two first blocking portions 222 are both arranged to face left, and the inclined surfaces of the two second blocking portions 232 are both arranged to face right.

[0068] It can be understood that the inclination angle of the inclined surface can be changed, and the change of the inclination angle is conducive to adjusting the magnitude of the external force pushing the first blocking member 22 and the second blocking member 23.

[0069] Exemplarily, the inclined surfaces of the first blocking portion 222 and the second blocking portion 232 have the same inclination angle.

[0070] Referring to the figure, in some embodiments, the first support portion 221 is provided with a first connection portion 223 on one side facing the second blocking member 23; the second support portion 231 is provided with a second connection portion 233 on one side facing the first blocking member 22; the elastic connection member 24 includes a first end 241 and a second end 242 that are arranged opposite to each other along the driving direction, the first end 241 is connected to the first connection portion 223, and the second end 242 is connected to the second connection portion 233. The elastic connection member 24 is a spring.

[0071] This arrangement facilitates the elastic connector 24 to produce elastic deformation under the action of external force. When the external force disappears, the elastic connector 24 recovers its deformation along the driving direction to facilitate the reset of the first blocking member 22 and the second blocking member 23, thereby improving the reset accuracy of the elastic connector 24.

[0072] Exemplarily, the first connection portion 223 and the second connection portion 233 have the same structure, and the first connection portion 223 and the second connection portion 233 are disposed opposite to each other along the left-right direction.

[0073] Exemplarily, a first protrusion and a second protrusion for connecting a spring are provided on the first connecting portion 223 and the second connecting portion 233. The first protrusion and the second protrusion are arranged opposite to each other along the left-right direction.

[0074] Exemplarily, the first end 241 of the spring is sleeved on the first protrusion and fixed to the first connecting portion 223 , and the second end 242 of the spring is sleeved on the second protrusion and fixed to the second connecting portion 233 .

[0075] refer to Figure 2 In some embodiments, the first blocking member 22 further includes a first reinforcing rib 224, the first reinforcing rib 224 is connected to the first supporting portion 221, the first reinforcing rib 224 is located between the two first blocking portions 222, and the projection of the first reinforcing rib 224 along the first direction avoids the plug-in structure 211 corresponding to the single plug hole 112;

[0076] The second blocking member 23 further includes a second reinforcing rib 234 . The second reinforcing rib 234 is connected to the second supporting portion 231 . The second reinforcing rib 234 is located between the two second blocking portions 232 .

[0077] In this way, the first reinforcing rib 224 is conducive to increasing the strength of the first blocking member 22, thereby reducing the deformation of the first blocking member 22. The second reinforcing rib 234 is conducive to increasing the strength of the second blocking member 23, thereby reducing the deformation of the second blocking member 23.

[0078] Exemplarily, the first reinforcing rib 224 is connected to the first supporting portion 221 along the up-down direction, and the second reinforcing rib 234 is connected to the second supporting portion 231 along the up-down direction.

[0079] refer to Figure 3 In some embodiments, the socket assembly 20 further includes a base 25, which is located on the side of the first blocking member 22 and the second blocking member 23 facing the conductive bar 21, the conductive bar 21, the first blocking member 22 and the second blocking member 23 are respectively connected to the base 25, and a plurality of limiting members 26 are protruding from the side of the base 25 facing the shell 10, a part of the limiting members 26 is used to limit the first blocking member 22 in the first avoidance position, and another part of the limiting members 26 is used to limit the second blocking member 23 in the second avoidance position.

[0080] In this way, the base 25 plays a supporting role to prevent the position of the conductive strip 21 from changing, and at the same time facilitates the limiting member 26 to limit the moving position of the first blocking member 22 and the second blocking member 23 .

[0081] Exemplarily, the side of the housing 10 having the insertion hole 11 faces forward, and the inside of the housing 10 includes the first blocking member 22 , the base 25 , and the conductive strip 21 from front to back.

[0083] Exemplarily, the limiting member 26 has a preset height along the first direction.

[0084] Exemplarily, the base 25 is made of a high temperature resistant and flame retardant plastic material to provide insulation and protection.

[0085] Exemplarily, a cavity is formed on a side of the base 25 facing the housing 10 , and the first blocking member 22 , the elastic connecting member 24 , and the second blocking member 23 are located inside the cavity and can move inside the cavity.

[0088] The first limiting member 261 is used to limit the first blocking portion 222 at the first avoidance position along the driving direction; the second limiting member 262 and the third limiting member 263 are used to limit the second blocking portion 232 at the second avoidance position along the driving direction.

[0089] With this arrangement, the first limiter 261 prevents the first blocking member 22 from moving too far after being acted upon by an external force, thereby making it difficult to accurately return to its original position. The second limiter 262 and the third limiter 263 prevent the second blocking member 23 from moving too far after being acted upon by an external force, thereby making it difficult to accurately return to its original position.

[0090] Exemplarily, the first blocking member 22 stops moving when the first stopper 261 abuts against the first reinforcing rib 224. The second blocking member 23 stops moving when the second stopper 262 abuts against the second reinforcing rib 234 and the third stopper 263 abuts against the second supporting portion 231.

[0092] The second blocking member 23 has a second arc surface 235 . The second arc surface 235 is located on the second reinforcing rib 234 , and the second arc surface 235 abuts against the base 25 .

[0093] The setting of the first arc surface 225 and the second arc surface 235 makes the first blocking member 22, the second blocking member 23 and the base 25 in a linear contact state, which can reduce the resistance when the first blocking member 22 and the second blocking member 23 move, and facilitate the first blocking member 22 and the second blocking member 23 to cover or expose the corresponding plug-in structure 211.

[0094] Exemplarily, the thickness of the first support portion 221 along the first direction is different, and the first arc surface 225 is located at the thickest part of the first support portion along the first direction.

[0095] Exemplarily, the first arc surface 225 extends in the up-down direction.

[0096] Exemplarily, the thickness of the second support portion 231 along the first direction is different, and the second reinforcing rib 234 is connected to the thickest part of the first support member along the first direction.

[0097] Exemplarily, the second arc surface 235 extends in the up-down direction.

[0098] In other embodiments, the first arc surface 225 may also be located on the first reinforcing rib 224 . The second arc surface 235 may also be located on the second supporting portion 231 .

[0099] Exemplarily, the contact portions between the base 25 and the first arc surface 225 and the second arc surface 235 are also arc surfaces.
