Description

Technical Field

[0001] This invention belongs to the field of power supply technology, specifically relating to a power supply and electrical system. Background Technology

[0002] A power supply is a device that provides electrical energy to various equipment or systems to ensure their normal operation. A power supply is a high-capacity portable power source with multiple data interfaces that can support various data connectors for connection. It is also easy to move, so it is widely used. In data centers, the application of power supplies is mainly focused on backup power and emergency power supply, providing backup power when the mains power is interrupted to ensure the continuous operation of critical equipment.

[0003] Currently available power supplies lack anti-tripping mechanisms for wiring harnesses. When a connector or other wiring harness is connected to the power supply, the wiring harness may be tripped, causing the connection between the connector and the power supply to slip, resulting in poor contact, affecting the stability of the power supply, and even causing the power supply to tip over and be damaged.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a power supply and electrical system.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a power supply and electrical system that can solve the problems of existing power supplies being inconvenient to match the required power values ​​and lacking anti-tripping mechanisms for wiring harnesses.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] A power supply includes: a base, an inverter module, multiple power modules, a wiring harness fixing mechanism, and multiple wiring harness buffering mechanisms.

[0009] The base is equipped with multiple casters at its bottom. The inverter module and multiple power modules are interlocked on the base, with the inverter module positioned at the top. Multiple pairs of connecting and fixing mechanisms are installed between the base and the power modules, between the power modules and the inverter module, and between every two power modules, to secure the base, inverter module, and multiple power modules together.

[0010] The wiring harness fixing mechanism is installed on the inverter module and includes: a connection port slot, a lower pressure plate, a pair of movable parts, an upper pressure plate, and a pair of locking assemblies. The connection port slot is carved into the inverter module, and the lower pressure plate is fixed to the edge of the connection port slot. The pair of movable parts slide on the two side walls of the connection port slot, and each of the movable parts has a groove carved at one end. L-shaped slots are carved on both side walls of the connection port slot, and a fixing shaft is fixed within each L-shaped slot. The fixing shaft is located in the groove, and the grooved end of each movable part is inserted into the L-shaped slot. The upper pressure plate is fixed between the pair of movable parts and is located on the lower pressure plate. Multiple corresponding wire grooves are carved on the lower and upper pressure plates. The pair of locking assemblies are respectively installed on the pair of movable parts to lock the movable parts onto the side walls of the connection port slot.

[0011] Multiple wiring harness buffer mechanisms are mounted on the outer wall of the inverter module. Each buffer mechanism includes a circular wire groove, a spring, a pull rope, and a connecting assembly. A mounting groove is formed in the bottom of the inverter module, and the circular wire groove rotates within it. The spring is mounted in the circular wire groove, and the pull rope is wrapped around the groove, with one end extending outside the inverter module. The connecting assembly is fixed to the end of the pull rope outside the inverter module and is used to secure the wiring harness.

[0012] In one embodiment of the present invention, multiple snap-fit ​​blocks are fixed to the bottom of each of the multiple power modules and inverter modules, and multiple snap-fit ​​slots adapted to the snap-fit ​​blocks are formed on the top of each of the multiple power modules and the base. The base and power modules, every two power modules, or the power modules and inverter modules are snapped into the snap-fit ​​slots by the snap-fit ​​blocks, thereby achieving mutual positioning and snap-fit. Power connectors are fixed to the bottom of each inverter module and the multiple power modules, and insertion holes adapted to the power connectors are formed on the top of each of the multiple power modules. When the inverter modules and the multiple inverter modules are snapped together, the power connectors are inserted into the insertion holes, thereby connecting the multiple power modules and the inverter module together.

[0013] In one embodiment of the present invention, the connecting and fixing mechanism includes: a rotating shaft, an arc-shaped locking rod, a locking tongue, and a locking block assembly. The rotating shaft rotates on the side wall of the power module or base and is located near the top. A rotating plate is fixed to one end of the rotating shaft located outside the power module or base. The arc-shaped locking rod is fixed to one end of the rotating shaft located inside the power module or base. The locking tongue is fixed to the side wall of the power module or inverter module and is located near the bottom. The arc-shaped locking rod is locked onto the locking tongue. The locking block assembly is installed inside the power module or base and is located at the top of the arc-shaped locking rod, used to lock the arc-shaped locking rod when it is locked onto the locking tongue.

[0014] When it is necessary to fix the base and power module, between two power modules, or between the power module and inverter module, the rotating plate drives the rotating shaft to rotate 180 degrees. The rotating shaft drives the arc-shaped locking rod to rotate 180 degrees around the rotating shaft as the axis. The arc-shaped locking rod rotates onto the locking tongue, and then the locking block assembly locks the arc-shaped locking rod, preventing it from rotating. Thus, the arc-shaped locking rod is locked onto the locking tongue, thereby fixing the base and power module, between two power modules, or between the power module and inverter module.

[0015] In one embodiment of the present invention, the locking block assembly includes: a locking block, a locking slot, and a first spring. The locking block slides within the power module or base and is located on the top of the arc-shaped locking rod. A control board is fixed within the power module or base via the locking block. The locking slot is carved into the arc-shaped locking rod, and the locking block is engaged therein. The upper corner of the locking block near the locking slot has an arc surface that facilitates the arc-shaped locking rod pushing the locking block. The first spring is installed between the locking block and the inner wall of the power module or base.

[0016] When the curved locking bar rotates onto the locking tongue, the end of the curved locking bar contacts the end of the locking block, pushing the locking block towards the first spring. When the locking block aligns with the locking slot, the spring force of the first spring pushes the locking block in the opposite direction, locking the curved locking bar in the locking slot and preventing it from rotating. When unlocking is required, the locking block can be pulled out of the locking slot by controlling the control panel.

[0017] In one embodiment of the present invention, the locking assembly includes: a sector-shaped locking block, a locking groove, and a pulling groove. The sector-shaped locking block rotates on a movable member. The locking groove is carved into the side walls of the connecting port groove, and one end of the sector-shaped locking block is engaged in the locking groove. The pulling groove is carved into the end of the sector-shaped locking block away from the locking groove. In use, the pulling groove drives the sector-shaped locking block to rotate, causing the end of the sector-shaped locking block near the locking groove to engage in the locking groove, thereby locking the pair of movable members on the side walls of the connecting port groove and preventing the movable members from sliding outward. When unlocking is required, the pulling groove also drives the sector-shaped locking block to rotate, causing the end of the sector-shaped locking block near the locking groove to rotate out of the locking groove.

[0018] In one embodiment of the present invention, a pair of retaining balls are installed in the side walls on both sides of the sector-shaped locking block within the movable member. Two pairs of spherical grooves are carved into the side walls of the sector-shaped locking block, and a second spring is installed between each pair of retaining balls and the inner wall of the movable member. The second springs push the retaining balls towards the sector-shaped locking block, causing the end of the retaining ball near the sector-shaped locking block to engage in the spherical groove, thereby stabilizing the sector-shaped locking block. The positions of the pair of spherical grooves correspond to the positions where the end of the sector-shaped locking block near the groove is engaged in the groove and where the end of the sector-shaped locking block near the groove rotates out of the groove.

[0019] In one embodiment of the present invention, an L-shaped clamping plate is fixed at the bottom of the upper pressure plate and in the middle of the upper pressure plate, and an L-shaped slot adapted to the L-shaped clamping plate is cut into the lower pressure plate. By positioning the L-shaped clamping plate in the middle of the upper pressure plate and engaging it in the L-shaped slot, the lower and upper pressure plates are auxiliaryly fixed when clamping the wire harness, preventing a gap between the middle position of the upper pressure plate and the lower pressure plate due to excessive length of the upper pressure plate, which would affect the clamping of the wire harness.

[0020] In one embodiment of the present invention, the connection assembly includes a connector and a Velcro strap. The connector is fixed to one end of a pull cord located outside the inverter module. The Velcro strap is attached to the connector. The wire harness is secured to the connector by the Velcro strap.

[0021] In one embodiment of the present invention, a retaining shaft is fixed at the center of the mounting groove, and the two ends of the spring are respectively fixed to the circular groove and the retaining shaft. The spring, by being fixed at its two ends to the retaining shaft and the circular groove, causes the spring to contract when the circular groove rotates. Simultaneously, the reverse force of the spring acts on the circular groove, causing it to rotate in the opposite direction when no external force is applied.

[0022] This invention also discloses an electrical system, including a power supply. The electrical system comprises a power control terminal, a charging / discharging module, a monitoring module, a heat dissipation module, and a power failure protection module. The power control terminal receives information transmitted from the charging / discharging module, the monitoring module, the heat dissipation module, and the power failure protection module, and issues corresponding commands. The monitoring module monitors the temperature and voltage / current anomalies of the power battery. When the battery temperature is detected to be too high, it transmits a signal to the power control terminal, which then controls the heat dissipation module to cool the battery. When the monitoring module detects abnormal voltage / current or excessively high battery temperature that may affect battery safety, it transmits an electrical signal to the power control terminal, which then controls the power failure protection module to cut off the power supply, or transmits an electrical signal to the charging / discharging module to stop charging or discharging.

[0023] Compared with the prior art, the power supply and electrical system of the present invention, on the one hand, by setting up multi-layer stackable power modules, can be combined and matched according to the required power supply value.

[0024] On the other hand, by setting up a wire harness fixing mechanism to fix the wire harness connection connector, and by using a wire harness buffering mechanism to provide a certain buffering effect when the wire harness is bumped, the stability of the wire harness connection to the power supply is effectively improved, and the problems of unstable plug connection and power supply tilting caused by the wire harness being bumped are reduced.

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0042] like Figure 1-13 As shown, a power supply according to one embodiment of the present invention includes: a base 1, an inverter module 102, multiple power modules 101, a wire harness fixing mechanism 2, and multiple wire harness buffering mechanisms 3.

[0043] like Figure 1-3 As shown, the base 1 has multiple casters 103 at its bottom. The inverter module 102 and multiple power modules 101 are interlocked on the base 1, with the inverter module 102 located at the top. Multiple pairs of connecting and fixing mechanisms 108 are respectively installed between the base 1 and the power modules 101, between the power modules 101 and the inverter module 102, and between every two power modules 101, for fixing the base 1, the inverter module 102, and the multiple power modules 101 together.

[0044] In practical use, the appropriate number of power modules 101 can be selected according to the required power level, and the base 1, inverter module 102, and multiple power modules 101 can be snapped together vertically. The connection state is then fixed by multiple pairs of connecting and fixing mechanisms 108.

[0045] like Figure 7-9 As shown, the wiring harness fixing mechanism 2 is installed on the inverter module 102. The wiring harness fixing mechanism 2 includes: a connection port groove 201, a lower pressure plate 202, a pair of moving parts 203, an upper pressure plate 204, and a pair of locking assemblies 209. The connection port groove 201 is carved into the inverter module 102, and the lower pressure plate 202 is fixed to the edge of the connection port groove 201. The pair of moving parts 203 slide on the two side walls of the connection port groove 201 respectively, and one end of each pair of moving parts 203 is carved with a sliding groove 205. L-shaped slots 207 are carved into the two side walls of the connection port groove 201, and a fixing shaft 208 is fixed in each L-shaped slot 207. The fixing shaft 208 is located in the sliding groove 205, and one end of the moving part 203 with the sliding groove 205 is inserted into the L-shaped slot 207. The upper pressure plate 204 is fixed between the pair of moving parts 203 and is located on the lower pressure plate 202. Multiple corresponding grooves 206 are cut into the lower pressure plate 202 and the upper pressure plate 204. A pair of locking assemblies 209 are respectively installed on a pair of moving parts 203, which are used to lock the moving parts 203 into the side wall of the connection port groove 201.

[0046] When connecting an external device's power plug to this device, first pull the upper pressure plate 204 outwards towards the connection port slot 201, causing the upper pressure plate 204 to move the moving part 203 outwards. As the moving part 203 moves outwards, the fixed shaft 208 moves from the inner end of the slide groove 205 to the outer end, and the end of the moving part 203 that cuts into the slide groove 205 is pulled out of the L-shaped slot 207. Then, rotate the upper pressure plate 204 upwards around the fixed shaft 208. Next, insert the plug into the corresponding socket in the connection port slot 201 and secure the wire harness in the wire groove 206 on the lower pressure plate 202. Then, rotate the upper pressure plate 204 in the opposite direction around the fixed shaft 208 and push the upper pressure plate 204 into the connection port slot 201, making the upper pressure plate 204 flush with the lower pressure plate 202. The upper pressure plate 204 drives the movable part 203 to re-insert one end of the groove 205 into the L-shaped slot 207, while the fixed shaft 208 moves again from the outer end to the inner end of the groove 205. This locks the movable part 203 in place via the L-shaped slot 207 and the fixed shaft 208. Furthermore, the locking assembly 209 locks the movable part 203 onto the side wall of the connection port slot 201, preventing it from sliding outwards. This fixes the movable part 203, and consequently, the upper pressure plate 204. Thus, the upper pressure plate 204 and the lower pressure plate 202 secure the wire harness at the connector, preventing it from loosening due to external pulling.

[0047] like Figure 9-10 As shown, multiple wire harness buffer mechanisms 3 are installed on the outer wall of the inverter module 102. Each wire harness buffer mechanism 3 includes a circular wire groove 302, a spring 304, a pull rope 305, and a connecting assembly 306. An installation groove 301 is carved into the bottom of the inverter module 102, and the circular wire groove 302 rotates within it. The spring 304 is installed in the circular wire groove 302, and the pull rope 305 is wrapped around the circular wire groove 302, with one end extending outside the inverter module 102. The connecting assembly 306 is fixed to the end of the pull rope 305 extending outside the inverter module 102 and is used to secure it to the wire harness.

[0048] In practical use, the middle position of the wire harness is bound to the connecting component 306, and the wire harness between the connecting component 306 and the wire groove 206 is in a slack state. If the wire harness is bumped by an external force, the wire harness is pulled outward. The wire harness pulls the pull rope 305 outward through the connecting component 306. The pull rope 305 drives the circular wire groove 302 to rotate. When the circular wire groove 302 rotates, it drives the spring 304 to contract. The rebound force of the spring 304 provides a buffer when the pull rope 305 is pulled outward. This provides a certain buffer when the wire harness is bumped, preventing the plug from loosening or the power supply from tipping over due to direct dragging.

[0049] like Figure 1-3As shown, multiple power modules 101 and inverter modules 102 are each fixed with multiple snap-fit ​​blocks 104 at their bottoms. Multiple snap-fit ​​slots 105, adapted to the snap-fit ​​blocks 104, are drilled on the tops of both the power modules 101 and the base 1. The base 1 and power modules 101, every two power modules 101, or power modules 101 and inverter modules 102 are secured to each other by snap-fit ​​blocks 104 within the snap-fit ​​slots 105, thus achieving mutual positioning and snap-fit. Power connectors 106 are fixed to the bottoms of inverter modules 102 and the multiple power modules 101, and sockets 107, adapted to the power connectors 106, are drilled on the tops of the multiple power modules 101. When inverter modules 102 and the multiple inverter modules 102 are snapped together, the power connectors 106 are inserted into the sockets 107, thereby connecting the multiple power modules 101 and inverter modules 102 together.

[0050] like Figure 3-6 As shown, the connecting and fixing mechanism 108 includes: a rotating shaft 112, an arc-shaped locking rod 109, a locking tongue 110, and a locking block assembly 113. The rotating shaft 112 rotates on the side wall of the power module 101 or the base 1 and is located near the top. A rotating plate 111 is fixed to one end of the rotating shaft 112 located outside the power module 101 or the base 1. The arc-shaped locking rod 109 is fixed to one end of the rotating shaft 112 located inside the power module 101 or the base 1. The locking tongue 110 is fixed to the side wall of the power module 101 or the inverter module 102 and is located near the bottom. The arc-shaped locking rod 109 is locked onto the locking tongue 110. The locking block assembly 113 is installed inside the power module 101 or the base 1 and is located on top of the arc-shaped locking rod 109. It is used to lock the arc-shaped locking rod 109 when it is locked onto the locking tongue 110.

[0051] When it is necessary to fix the base 1 and the power module 101, between every two power modules 101, or between the power module 101 and the inverter module 102, the rotating plate 111 drives the rotating shaft 112 to rotate 180 degrees, causing the rotating shaft 112 to drive the arc-shaped locking rod 109 to rotate 180 degrees around the rotating shaft 112 as the axis, so that the arc-shaped locking rod 109 rotates onto the locking tongue 110, and then the locking block assembly 113 locks the arc-shaped locking rod 109 so that it cannot rotate. Thus, the arc-shaped locking rod 109 is locked onto the locking tongue 110, thereby fixing the base 1 and the power module 101, between every two power modules 101, or between the power module 101 and the inverter module 102.

[0052] like Figure 3-6As shown, the locking block assembly 113 includes a locking block 114, a locking slot 115, and a first spring 117. The locking block 114 slides within the power module 101 or the base 1 and is located on the top of the arc-shaped locking rod 109. A control plate 116 is fixed within the power module 101 or the base 1. The locking slot 115 is carved into the arc-shaped locking rod 109, and the locking block 114 is engaged therein. The upper corner of the end of the locking block 114 near the locking slot 115 has an arc surface that facilitates the arc-shaped locking rod 109 to push the locking block 114. The first spring 117 is installed between the locking block 114 and the inner wall of the power module 101 or the base 1.

[0053] When the arc-shaped locking rod 109 rotates onto the locking tongue 110, the end of the arc-shaped locking rod 109 contacts the end of the locking block 114, pushing the locking block 114 towards the first spring 117. When the locking block 114 aligns with the slot 115, the elastic force of the first spring 117 pushes the locking block 114 in the opposite direction, causing the locking block 114 to lock in the slot 115, thereby locking the arc-shaped locking rod 109 and preventing it from rotating. When unlocking is required, the locking block 114 can be pulled out of the slot 115 by the control plate 116.

[0054] like Figure 7-12 As shown, the locking assembly 209 includes: a sector-shaped locking block 210, a locking groove 211, and a pull groove 215. The sector-shaped locking block 210 rotates on the moving member 203. The locking groove 211 is carved into the two side walls of the connecting port groove 201, and one end of the sector-shaped locking block 210 is engaged in the locking groove 211. The pull groove 215 is carved into the end of the sector-shaped locking block 210 away from the locking groove 211. In use, the sector-shaped locking block 210 is rotated by the pull groove 215, so that the end of the sector-shaped locking block 210 near the locking groove 211 is engaged in the locking groove 211, thereby locking the pair of moving members 203 on the side wall of the connecting port groove 201 and preventing the moving members 203 from sliding outward. When unlocking is required, the sector-shaped locking block 210 is rotated by the pull groove 215, so that the end of the sector-shaped locking block 210 near the locking groove 211 rotates out of the locking groove 211.

[0055] like Figure 11-12 As shown, a pair of retaining balls 212 are installed in the side walls on both sides of the sector-shaped locking block 210 within the moving member 203. Two pairs of spherical grooves 214 are carved into the side walls of the sector-shaped locking block 210. A second spring 213 is installed between each pair of retaining balls 212 and the inner wall of the moving member 203. The second springs 213 push the retaining balls 212 towards the sector-shaped locking block 210, causing one end of the retaining ball 212 near the sector-shaped locking block 210 to be engaged in the spherical groove 214, thereby stabilizing the sector-shaped locking block 210. The positions of the pair of spherical grooves 214 correspond to the positions where one end of the sector-shaped locking block 210 near the locking groove 211 is engaged in the locking groove 211 and the positions where one end of the sector-shaped locking block 210 near the locking groove 211 is rotated out of the locking groove 211.

[0056] like Figure 7-11 As shown, an L-shaped clamping plate 216 is fixed at the bottom and in the middle of the upper pressure plate 204, and an L-shaped slot 217 adapted to the L-shaped clamping plate 216 is cut into the lower pressure plate 202. By positioning the L-shaped clamping plate 216 in the middle of the upper pressure plate 204 and locking it in the L-shaped slot 217, the lower pressure plate 202 and the upper pressure plate 204 are auxiliaryly fixed when clamping the wire harness, preventing gaps between the middle position of the upper pressure plate 204 and the lower pressure plate 202 due to the excessive length of the upper pressure plate 204, which would affect the clamping of the wire harness.

[0057] like Figure 10 and 13 As shown, the connecting assembly 306 includes a connector 307 and a Velcro strap 308. The connector 307 is fixed to one end of the pull cord 305 located outside the inverter module 102. The Velcro strap 308 is installed on the connector 307. The wire harness is tightened to the connector 307 by the Velcro strap 308. A retaining pin 303 is fixed at the center of the mounting slot 301, and the two ends of the spring 304 are fixed to the circular wire groove 302 and the retaining pin 303, respectively. The spring 304 is fixed to the retaining pin 303 and the circular wire groove 302, respectively, so that when the circular wire groove 302 rotates, it drives the spring 304 to contract. At the same time, the reverse elastic force of the spring 304 also acts on the circular wire groove 302, so that the circular wire groove 302 rotates in the opposite direction when no external force is applied.

[0058] like Figure 2 As shown, the present invention also discloses an electrical system comprising the aforementioned power supply. The electrical system includes: a power control terminal, a charging / discharging module, a monitoring module, a heat dissipation module, and a power failure protection module. The power control terminal receives information transmitted from the charging / discharging module, the monitoring module, the heat dissipation module, and the power failure protection module, and issues corresponding commands. The monitoring module monitors the temperature and voltage / current anomalies of the power battery. When it detects that the battery temperature is too high, it transmits a signal to the power control terminal, which then controls the heat dissipation module to cool the battery. When the monitoring module detects abnormal voltage / current or excessively high battery temperature that may affect battery safety, it transmits an electrical signal to the power control terminal, which then controls the power failure protection module to perform power failure protection, or transmits an electrical signal to the charging / discharging module to stop charging or discharging.

[0059] Working principle: When in use, select the appropriate number of power modules 101 according to the required power value, and snap the base 1, inverter module 102 and multiple power modules 101 together vertically. After the connection is fixed by multiple pairs of connecting and fixing mechanisms 108, the connection state of the base 1, inverter module 102 and multiple power modules 101 is fixed. When fixed, the rotating plate 111 drives the rotating shaft 112 to rotate 180 degrees, causing the rotating shaft 112 to drive the arc-shaped locking rod 109 to rotate 180 degrees around the rotating shaft 112 as the axis, so that the arc-shaped locking rod 109 rotates onto the locking tongue 110. When the arc-shaped locking rod 109 rotates to its end, the end of the arc-shaped locking rod 109 contacts the end of the locking block 114, pushing the locking block 114 towards the first spring 117. When the locking block 114 is aligned with the locking groove 115, the elastic force of the first spring 117 pushes the locking block 114 in the opposite direction, so that the locking block 114 is locked in the locking groove 115, thereby locking the arc-shaped locking rod 109 and preventing it from rotating, thus fixing it.

[0060] When connecting the power plug of an external device to this device, first pull the upper pressure plate 204 outwards towards the connection port slot 201, causing the upper pressure plate 204 to move the moving part 203 outwards. As the moving part 203 moves outwards, the fixed shaft 208 moves from the inner end of the slide groove 205 to the outer end, and the end of the moving part 203 that cuts into the slide groove 205 is pulled out of the L-shaped slot 207. Then, rotate the upper pressure plate 204 upwards around the fixed shaft 208. Next, insert the plug into the corresponding socket in the connection port slot 201 and secure the wire harness in the wire groove 206 on the lower pressure plate 202. Then, rotate the upper pressure plate 204 in the opposite direction around the fixed shaft 208 and push the upper pressure plate 204 into the connection port slot 201, making the upper pressure plate 204 flush with the lower pressure plate 202.

[0061] The upper pressure plate 204 drives the movable part 203 to re-insert one end of the groove 205 into the L-shaped slot 207, while the fixed shaft 208 moves from the outer end to the inner end of the groove 205. This locks the movable part 203 in place via the L-shaped slot 207 and the fixed shaft 208. Additionally, the pulling groove 215 rotates the sector-shaped locking block 210, causing one end of the sector-shaped locking block 210 near the locking groove 211 to engage in the locking groove 211, thus locking the movable part 203 against the side wall of the connection port groove 201 and preventing it from sliding outwards. This fixes the movable part 203 and also fixes the upper pressure plate 204. Thus, the upper pressure plate 204 and the lower pressure plate 202 fix the wire harness at the connector, preventing the connector from loosening due to external pulling.

[0062] Simultaneously, the middle of the wire harness is secured to the connector 307 via Velcro strap 308, and the wire harness between the Velcro strap 308 and the wire groove 206 is kept slack. If the wire harness is bumped by an external force, pulling the wire harness outward will cause the pull cord 305 to pull outward through the connector 307. The pull cord 305 drives the circular wire groove 302 to rotate, and the rotation of the circular wire groove 302 causes the spring 304 to contract. The rebound force of the spring 304 cushions the outward pull of the pull cord 305. This provides a certain buffering effect when the wire harness is bumped, preventing the plug from loosening or the power supply from tipping over due to direct dragging.
