Description

Technical Field

[0001] This utility model relates to the field of rectifiers, specifically a quick-install rectifier for UPS systems. Background Technology

[0002] A rectifier utilizes the unidirectional conductivity of rectifier elements to process the positive and negative half-cycles of alternating current (AC), ensuring that the output current flows in only one direction, thus converting AC to DC. For example, in a bridge rectifier circuit, four diodes are connected in a specific manner, conducting during the positive and negative half-cycles of AC, converting both halves of the AC current into DC in the same direction. In a UPS system, the rectifier is a device that converts AC to DC. It converts the input AC mains power into DC to charge the batteries in the UPS system and provide a stable DC power supply for subsequent inverter stages. This ensures that when the mains power is normal, electrical energy can be efficiently and stably converted into a form suitable for battery storage and equipment use. When the mains power is interrupted, it works with the battery to continuously provide stable power to the load.

[0003] When traditional rectifiers are installed in the chassis of a UPS system, they are often secured by clips. The friction and fixing force provided by the clips ensure the stability of the rectifier. However, since some mechanical components in the UPS vibrate during operation, the rectifier casing and the clips constantly come into contact and rub against each other. Over time, this causes wear on the casing, which in turn affects the performance and lifespan of the rectifier. Furthermore, when the rectifier is clipped into the clips, the casing fits snugly against the clips, which reduces its heat dissipation capacity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-install rectifier for UPS systems, which solves the problem that the continuous contact and friction between the rectifier housing and the slot will cause wear on the housing over time, thus affecting the performance and service life of the rectifier. Moreover, when the rectifier is inserted into the slot, the housing of the rectifier fits snugly against the slot, which will reduce its heat dissipation capacity.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-install rectifier for a UPS system, comprising a rectifier body, wherein a support structure is provided on the outer shell of the rectifier body, and the support structure contacts a slot for installing the rectifier body, thereby forming a gap between the rectifier body and the slot.

[0006] The support structure includes a main body component, two sliding components, and an elastic component. The main body component is used to move along the outer shell of the rectifier body, and both sliding components are slidably connected to the main body component.

[0007] The rectifier body is also provided with a limiting mechanism. The limiting component of the limiting mechanism is used to rotate around its fulcrum to the limit position and stop. The limiting component, sliding component and elastic component cooperate to form a clamping structure to maintain the relative stability of the rectifier body and the slot.

[0008] Preferably, there are two support structures, and the two support structures are located on both sides of the rectifier body.

[0009] Preferably, a limiting groove is formed on the outer shell of the rectifier body, and a slider is slidably connected inside the limiting groove. The slider is fixedly connected to the main frame of the support structure.

[0010] Preferably, the elastic component includes a spring, a fixing block, and a fixing plate. The two ends of the spring are fixedly connected to the fixing block and the fixing plate, respectively. The fixing block is fixed to the outer shell of the rectifier body, and the fixing plate is fixed to the main body component.

[0011] Preferably, a protrusion is fixedly connected to one side of the fixing plate, and the protrusion is located between the two sliding components.

[0012] Preferably, an elastic sheet is fixedly connected between the two sliding components.

[0013] Preferably, the support structure further includes two symmetrical buffer pads, both of which are fixedly connected to the main body component.

[0014] Preferably, an arc-shaped soft pad is fixedly connected to the end of the sliding component away from the elastic sheet.

[0015] Preferably, the limiting mechanism further includes a fixing member, a rotating shaft, and a torsion spring. The fixing member is fixedly connected to the housing of the rectifier, the rotating shaft is fixedly connected to the fixing member, the limiting member is rotatably connected to the rotating shaft, and the two ends of the torsion spring are fixedly connected to the fixing member and the limiting member, respectively.

[0016] Preferably, the limiting component has an arc-shaped groove inside, and an arc-shaped block is fixedly connected to the outer surface of the rotating shaft, with the arc-shaped block located inside the arc-shaped groove.

[0017] Compared with existing technologies, this utility model has the following advantages: Through the designed support structure, buffer pad, and limiting mechanism, during installation, the rectifier body only needs to be inserted into the slot. The cooperation of the support structure and limiting mechanism enables rapid installation and automatically maintains relative stability between the rectifier body and the slot. Compared to the traditional method of using the friction and fixing force provided by the slot, its stability is higher. Furthermore, the combination of the buffer pad and spring provides cushioning and shock absorption. The cooperation between the buffer pad and the main components of the support structure also prevents the rectifier body from contacting the slot, creating a larger gap between them, which facilitates heat dissipation. This solves the problem of wear on the outer casing over time, which affects the rectifier's performance and lifespan. The rectifier body is not only quick to install but also easier and less labor-intensive to disassemble. Attached Figure Description

[0026] like Figures 1-7As shown, a quick-install rectifier for a UPS system includes a rectifier body 1. A support structure 2 is provided on the outer casing of the rectifier body 1. The support structure 2 contacts a slot 3 for mounting the rectifier body 1, creating a gap between the rectifier body 1 and the slot 3 to improve the heat dissipation capacity of the rectifier body 1. Two support structures 2 are provided, located on opposite sides of the rectifier body 1. A limiting groove is provided on the outer casing of the rectifier body 1, and a slider 5 is slidably connected inside the limiting groove. The slider 5 is fixedly connected to the main frame of the support structure 2. An elastic component 20... 3 includes a spring 2031, a fixing block 2032, and a fixing plate 2033. The two ends of the spring 2031 are fixedly connected to the fixing block 2032 and the fixing plate 2033 respectively. The fixing block 2032 is fixed to the outer shell of the rectifier body 1. The fixing plate 2033 is fixed to the main body component 201. A protrusion 6 is fixedly connected to one side of the fixing plate 2033. The protrusion 6 is located between two sliding components 202 and is used to limit the maximum displacement of the sliding components 202 and prevent the sliding components 202 from detaching from the main body component 201. An elastic sheet 7 is fixedly connected between the two sliding components 202.

[0027] The support structure 2 includes a main component 201, two sliding components 202 and an elastic component 203. The main component 201 is used to move along the outer shell of the rectifier body 1. Both sliding components 202 are slidably connected to the main component 201. The support structure 2 also includes two symmetrical buffer pads 8. Both buffer pads 8 are fixedly connected to the main component 201. Both ends of the buffer pads 8 are rounded. An arc-shaped soft pad 9 is fixedly connected to the end of the sliding component 202 away from the elastic sheet 7.

[0028] A limiting mechanism 4 is also provided on the outer shell of the rectifier body 1. The limiting component 401 of the limiting mechanism 4 is used to rotate around its fulcrum to the limit position and stop. The limiting component 401, the sliding component 202 and the elastic component 203 cooperate to form a clamping structure to maintain the relative stability of the rectifier body 1 and the slot 3. The limiting mechanism 4 also includes a fixing component 402, a rotating shaft 403 and a torsion spring. The fixing component 402 is fixedly connected to the outer shell of the rectifier, the rotating shaft 403 is fixedly connected to the fixing component 402, and the limiting component 401 rotates with the rotating shaft 403. The torsion spring is fixedly connected to the fixing member 402 and the limiting member 401 at both ends, so that the limiting member 401 can rotate stably with the rotating shaft 403 as the fulcrum. The limiting member 401 has an arc groove 10 inside, and an arc block 11 is fixedly connected to the outer surface of the rotating shaft 403. The arc block 11 is located in the arc groove 10. When the limiting member 401 drives the arc groove 10 inside to rotate, the arc block 11 can abut against the arc groove 10, limit the rotation angle of the arc groove 10, and thus limit the rotation angle of the limiting member 401.

[0029] Working principle:

[0030] like Figure 1 As shown, before installation, the spring 2031 in the elastic component 203 is in a stationary state. During installation, the slot 3 is first pre-installed in the UPS chassis, and then the rectifier body 1 and the support structures 2 on both sides of the rectifier are inserted into the slot 3. When inserted, the end of the rectifier body 1 closest to the limiting mechanism 4 is inserted first from one end of the slot 3. During this process, the inner top wall and inner bottom wall of the slot 3 respectively squeeze the two sets of buffer pads 8, and the two main components 201 move along the two inner side walls of the slot 3 respectively. When both sets of sliding components 202 abut against one side of the slot 3, as shown... Figures 2-4 As shown, the sliding component 202 and the main component 201 stop moving due to the resistance of the slot 3. The rectifier body 1 drives the limiting mechanism 4 to continue moving. During the movement, since the fixed plate 2033 is fixedly connected to the main component 201 and the fixed block 2032 is fixedly connected to the rectifier body 1, the position of the fixed plate 2033 remains unchanged. The fixed block 2032 moves with the rectifier body 1, pulling the spring 2031 and causing the spring 2031 to deform, preparing for subsequent clamping work. Moreover, since the limiting component 401 can rotate around the rotating shaft 403, when the limiting component 401 contacts the slot 3 and the main component 201, it will not cause interference, but will pass over the main component 201. When the limiting component 401 moves along the inner wall of the slot 3, it will be squeezed by the slot 3 and tilt. Figure 4 and Figure 7As shown, when the rectifier body 1 moves the limiting component 401 to a position beyond the other end of the slot 3, under the action of the torsion spring, the limiting component 401 rotates to its original angle. At this time, under the action of the spring 2031, a force is generated that brings the fixing block 2032 and the fixing plate 2033 closer together, causing the rectifier body 1 and the main component 201 to move closer together, thereby causing the limiting component 401 to abut against the other end of the slot 3. Thus, under the action of the elastic component 203 and the limiting mechanism 4, the limiting component 401 can work with the slider 5 to clamp the slot 3, forming a stable structure between the rectifier body 1 and the support structure 2. In summary, during installation, it is only necessary to push the rectifier body 1 into the slot 3. The cooperation of the support structure 2 and the limiting mechanism 4 can achieve quick installation and automatically maintain the relative stability between the rectifier body 1 and the slot 3. It should be noted that the stability between the two relies on the tension of the spring 2031 on the one hand, and on the resistance between the buffer pad 8 and the slot 3 and the main component 201 and the... The resistance between the slots 3 is a significant improvement. Traditionally, when rectifiers are installed in the chassis of a UPS system, they are often fixed in slots 3. The shape of the rectifier matches the slot 3; the rectifier is aligned with the slot 3 and then pushed in forcefully to lock it into place. The friction and fixing force provided by the slot 3 ensure the rectifier remains stable. This rectifier offers higher stability compared to existing technologies. Furthermore, the combination of the buffer pad 8 and the spring 2031 provides cushioning and shock absorption. Since some mechanical components in the UPS vibrate during operation, the rectifier casing constantly contacts and rubs against the slot 3, causing wear over time. In this rectifier, the buffer pad 8 and the main body component 201 of the support structure 2 work together to support the rectifier body 1, preventing it from contacting the slot 3 and creating a larger gap between them. This facilitates heat dissipation and solves the problem of wear on the casing over time, which affects the rectifier's performance and lifespan.

[0031] Next, when it is necessary to remove the rectifier body 1 from the slot 3, simply pinch the two sets of sliding parts 202 to move the sliding parts 202 towards the protrusion 6. During the movement, the sliding parts 202 will squeeze the elastic sheet 7 and cause it to deform. When the sliding parts 202 reach the position that contacts the protrusion 6, the sliding parts 202 stop moving. At this time, the sliding parts 202 should retract into the main body part 201. At this time, since the spring 2031 is in a stretched state, the position of the limiting mechanism 4 connected to the rectifier body 1 remains unchanged. The spring 2031 pulls the fixing plate 2033 towards the limiting mechanism 4, thereby causing the main body part 201 to move along the slot 3. During the movement, a part of the main body part 201 will protrude from the slot 3, making it easier to pull the protruding part of the main body part 201 to rectify. The main body 1 and the supporting structure 2 are removed from the slot 3, which improves the convenience of disassembly. It should be noted that during the movement of the main body structure along the slot 3, the sliding component 202 needs to be released. Under the elastic force of the elastic sheet 7, the sliding component 202 will move towards the slot 3, so that the sliding component 202 drives the soft pad 9 to press against the inner wall of the slot 3. Since the soft pad 9 is soft and arc-shaped, it will not scratch the slot 3. When the sliding component 202 pushes the soft pad 9 to press against the inner wall of the slot 3, it will also generate resistance to avoid the impact damage caused by the spring 2031 quickly pulling the fixing plate 2033 and the main body component 201. Moreover, the tension of the spring 2031 should be greater than the resistance encountered by the main body component 201 during the movement to ensure that the main body component 201 can effectively move a certain distance automatically.
