Description

Technical Field

[0001] The present application relates to the technical field of power supply aging testing, and in particular to an aging cabinet for switching power supply products that is easy to install. Background Art

[0002] As an important component of modern electronic equipment, switching power supplies are widely used in computers, communication equipment, industrial automation and other fields. In order to ensure the reliability and performance of switching power supplies, strict aging tests must be carried out before the products leave the factory.

[0003] Currently, an aging cabinet is usually used to perform aging tests on multiple switching power supplies in batches. During the aging test, workers are required to install and disassemble the multiple switching power supplies on the aging cabinet.

[0004] At present, the common way to install the switching power supply on the aging cabinet is mainly manual fixing, usually using bolts or clips to fix the switching power supply on the aging cabinet. Although it can effectively reduce costs, each installation and removal of the switching power supply requires a lot of time and manpower, which can easily cause fatigue to the staff, thereby reducing the efficiency of the staff in performing aging tests on the switching power supply. Summary of the invention

[0005] The present application provides an easy-to-install aging cabinet for switching power supply products, which can facilitate the disassembly and assembly of the switching power supply on the aging cabinet, and can effectively ensure the position stability of the switching power supply after installation on the aging cabinet.

[0010] The locking device comprises a plurality of first elastic members, a locking member and a plurality of electromagnets; the locking member is movably arranged on the mounting plate and can move in a vertical direction at the top of the adjacent mounting space; the two ends of the first elastic member are respectively connected to the locking member and the corresponding mounting plate, and have a tendency to drive the locking member to move in a direction close to the corresponding mounting plate; the electromagnet is located below the locking member and is arranged on the adjacent mounting plate, and one side of the electromagnet has a space in the mounting space for installing the switching power supply;

[0011] The plurality of positioning devices correspond to the plurality of locking devices one by one, and the latch is located below the corresponding locking member;

[0012] The control device is arranged at the bottom of the cavity, and is electrically connected to a plurality of the electromagnets. When the control device supplies power to the switching power supply, the electromagnets are energized, and after being energized, the electromagnets can drive the corresponding locking members to move downward to lock the switching power supply.

[0013] By adopting the above technical solution, after the switching power supply is placed in the installation space and plugged into the pin, the control device can be started to control the locking device to lock the position of the switching power supply in the installation space. At the same time, the switching power supply is powered to start the aging test, which can facilitate the disassembly and assembly of the switching power supply on the aging cabinet and effectively ensure the position stability of the switching power supply after installation on the aging cabinet.

[0014] Optionally, the positioning device further comprises two positioning plates, the positioning plates are arranged on the mounting plate and are located below the corresponding locking members, and a mounting groove adapted to the switching power supply is formed between the two positioning plates;

[0015] The locking device comprises two electromagnets in total, and the two electromagnets are respectively located at one side of the corresponding two positioning plates away from the mounting groove.

[0016] By adopting the above technical solution, it is convenient for workers to determine the installation position of the switching power supply in the installation space, so that the switching power supply can be accurately fixed by the positioning device and the locking device during installation.

[0017] Optionally, the positioning plate is made of magnetic isolation material.

[0018] By adopting the above technical solution, the positioning plate can reduce the influence of the electromagnet on the switching power supply after being energized, thereby effectively ensuring the effect of the switching power supply aging test.

[0019] Optionally, the positioning device also includes two sliding members with magnetic isolation effect and a plurality of second elastic members; the two sliding members are respectively arranged on the two positioning plates, and the sliding members are slidably connected to the positioning plates along the vertical direction; the two ends of the second elastic member are respectively connected to the sliding member and the positioning plate, and have a tendency to drive the sliding member to slide and contact and resist the locking member above.

[0020] By adopting the above technical solution, the sliding part and the positioning plate can jointly have a magnetic isolation effect on the switching power supply installed in the installation slot, thereby further reducing the probability of the switching power supply being affected by the electromagnet; at the same time, it can facilitate the locking device of switching power supplies of different heights in the installation slot, thereby improving the adaptability to switching power supplies of different sizes.

[0024] By adopting the above technical solution, during the process of locking the switch power supply in position by the locking device, the sliding member can be driven to slide and squeeze the second elastic member, and then the second elastic member drives the movable member to overcome the force of the third elastic member and move to contact and resist the side of the switch power supply, thereby further improving the installation and fixing effect of the switch power supply in the installation groove.

[0025] Optionally, the movable part is elastic, and can move toward a direction close to the corresponding latch until it contacts and abuts against the switch power supply located in the installation slot.

[0026] By adopting the above technical solution, the wear of the movable parts on the switching power supply can be reduced, and the force applied by the movable parts to the switching power supply can further effectively suppress the displacement of the switching power supply in the installation slot.

[0029] By adopting the above technical solution, the staff can conveniently control the rotating part to rotate to a suitable angle according to the positioning requirements of the switching power supply, so that the movable part can exert force on the switching power supply at a suitable angle to achieve a suitable positioning effect on the switching power supply.

[0030] Optionally, when the rotating member rotates to the extreme position in the direction approaching the corresponding latch, the movable member is completely located in the yield groove under the action of the third elastic member; when the rotating member rotates to the extreme position in the direction away from the corresponding latch, the movable member is partially located in the corresponding installation groove under the action of the third elastic member.

[0031] By adopting the above technical solution, when the size of the switching power supply is small and there is a distance between it and the positioning plate after it is installed in the installation slot, the positioning device can preferentially limit the displacement of the switching power supply in the installation slot toward the positioning plate; when the size of the switching power supply is compatible with the installation slot, the positioning device can mainly limit the displacement of the switching power supply along the plugging direction of the pin.

[0032] Optionally, the positioning assembly further includes a fourth elastic member; both ends of the fourth elastic member are respectively connected to the rotating member and the positioning plate, and can drive the rotating member to rotate in a direction away from the corresponding latch to an extreme position and maintain the trend.

[0033] By adopting the above technical solution, the positioning component can be automatically adapted and adjusted according to the size of the switching power supply, so that the rotating member is rotated to a suitable angle to position the switching power supply.

[0034] Optionally, the positioning plate further has a transition space between the give-way groove and the filling space; the filling space is connected to the corresponding give-way groove through the transition space, and the transition space is narrowed in a direction approaching the corresponding give-way groove.

At this time, the locking member 41 is located above the two sliding members 32 when they slide upward to the limit position relative to the positioning plate 31, and there is a gap between the two sliding members 32, and the gap between the locking member 41 and the adjacent mounting plate 21 below it is greater than the height dimension of the largest size of the switching power supply 6. In this embodiment, it is preferred that the first elastic member 42 is a spring.

[0076] The two electromagnets 43 are respectively fixedly installed on both sides of the corresponding positioning device 3, fixedly connected on the mounting plate 21, and respectively located on the side of the two positioning plates 31 away from the mounting groove 13; the downward projection of the locking member 41 in the vertical direction exceeds the position of the corresponding positioning device 3, and the above-mentioned parts have two places and are respectively aligned with the two electromagnets 43 in the vertical direction and the range is adapted.

[0077] Reference Figure 1 and Figure 2 , an external circuit is connected between the electromagnet 43 and the control device 5, that is, the control device 5 can supply power to the electromagnet 43, and preferably the control device 5 supplies power to the two electromagnets 43 and the corresponding switch power supply 6 simultaneously and synchronously. In this embodiment, since the above operation is a common prior art, it is not described here, and the related circuits are omitted in the drawings.

[0078] The locking member 41 is magnetic, and when the control device 5 supplies power to the electromagnet 43, that is, the electromagnet 43 is energized, it can attract the locking member 41 to overcome the force of the first elastic member 42 and move downward until the locking member 41 contacts and abuts against the top of the switching power supply 6 installed in the installation slot 13, and at this time, the displacement of the switching power supply 6 in the installation slot 13 along the vertical direction is limited. In this embodiment, since the electromagnet 43 and its functions are common existing technologies, they are not described in detail here, and they are only briefly shown in the drawings.

[0079] At this time, when the control device 5 is started to supply power to the switching power supply 6 for the aging test, the corresponding locking device 4 will also be started, and the corresponding locking member 41 will apply a force to the switching power supply 6 to lock its position to ensure that the aging test is carried out stably; when the aging test is completed and the control device 5 is turned off to supply power to the switching power supply 6, the corresponding locking device 4 will also stop working and release the lock on the switching power supply 6.

[0080] Furthermore, in order to reduce the influence of the electromagnet 43 on the switch power supply 6 installed in the installation slot 13 after being energized, the positioning plate 31 and the sliding member 32 are preferably made of magnetic isolation material. In this embodiment, since the magnetic isolation material is a material used to prevent the conduction of the magnetic field, which is a common prior art, the type of magnetic isolation material is not further limited here.

[0081] Reference Figure 3 and Figure 5When the width dimension of the switch power supply 6 to be fixed in the installation slot 13 is large, due to its large size, its mass is also large, and the probability of its displacement in the horizontal direction due to vibration during the aging test is higher; when the switch power supply 6 moves into the installation slot 13 along the width direction of the cabinet 1 and the plug 35 is plugged into the socket 61 on the shell of the switch power supply 6, the switch power supply 6 will successively contact the movable parts 342 of the plurality of positioning components 34, and at the same time successively drive the corresponding plurality of rotating parts 341 of the positioning components 34 to move away from the opening of the cavity 11. Rotate to the extreme position; thereafter, after the corresponding locking device 4 is activated, the locking member 41 will apply a vertical downward force to the corresponding two sliding members 32, driving the corresponding second elastic member 33 to deform, and the deformed second elastic member 33 will partially enter the multiple transition spaces 313 and contact and abut against the end of the corresponding movable member 342 and apply a force to it. At this time, the other end of the movable member 342 can not only contact and abut against one side of the switching power supply 6, but also the force applied to the switching power supply 6 can limit the horizontal displacement of the switching power supply 6 in the mounting slot 13.

[0082] Reference Figure 3 and Figure 6 When the width dimension of the switch power supply 6 to be fixed in the installation slot 13 is small, due to its small size, its mass is also small, and the probability of its displacement in the horizontal direction due to vibration during the aging test is low, and it mainly displaces in the direction parallel to the length of the cabinet 1; when the switch power supply 6 moves into the installation slot 13 along the width direction of the cabinet 1 and the pin 35 is plugged into the socket 61 on the shell of the switch power supply 6, the switch power supply 6 can be installed in the installation slot 13 without contacting the positioning component 34; thereafter, after the corresponding locking device 4 is activated, the locking member 41 will engage the corresponding two sliding members 32 A vertical downward force is applied to drive the corresponding second elastic member 33 to deform. The deformed second elastic member 33 will partially enter the multiple transition spaces 313, contact and abut against the end of the corresponding movable member 342 and apply a force to it. At this time, the other end of the movable member 342 can not only contact and abut against one side of the switching power supply 6, but also the force applied to the switching power supply 6 can mainly limit the displacement of the switching power supply 6 in the installation groove 13 along the direction parallel to the length direction of the cabinet 1. At the same time, the friction between the movable member 342 and the switching power supply 6 can limit the displacement of the switching power supply 6 in the installation groove 13 along the direction parallel to the width direction of the cabinet 1.

[0083] In the process of the switch power supply 6 moving along the width direction of the cabinet 1 into the installation groove 13 and making the pin 35 plug and cooperate with the socket 61 on the shell of the switch power supply 6, if the switch power supply 6 contacts the end of the movable part 342 of the partial positioning assembly 34, it drives the corresponding rotating part 341 to overcome the force of the corresponding fourth elastic part 344 to rotate. In the process, the force of the fourth elastic part 344 on the rotating part 341 can also drive the switch power supply 6 to move in the direction away from the positioning assembly 34, thereby achieving the effect of correction, which makes it easier for the switch power supply 6 to find a more accurate installation position in the installation groove 13.

[0084] The implementation principle of a switching power supply product aging cabinet that is easy to install in the embodiment of the present application is as follows:

[0085] When performing an aging test on multiple switching power supplies 6, first place the switching power supplies 6 in the installation slot 13 in a horizontal direction, so that the plug 35 is plugged into the plug hole 61 on the shell and abuts against the inner wall of the cavity 11 away from the opening thereof;

[0086] Then, the control device 5 supplies power to the switch power supply 6 and the corresponding two electromagnets 43. After the two electromagnets 43 are energized, they will jointly drive the locking member 41 to move downward and contact with the top of the switch power supply 6 to achieve vertical locking. At the same time, the corresponding two sliding members 32 will slide downward under the vertical downward force, squeezing the corresponding two second elastic members 33 to deform them. After the second elastic members 33 are deformed, they will trigger the adjacent multiple positioning components 34, so that the multiple movable members 342 move toward the direction close to the switch power supply 6 and contact with it, and exert symmetrical and inward forces on both sides of the switch power supply 6 to achieve horizontal positioning of the switch power supply 6.

[0087] At this time, the switch power supply 6 can be subjected to the aging test in a stable position, thereby reducing the probability that the switch power supply 6 is displaced due to vibration during the aging test, thereby affecting the aging test.

[0088] After the aging test of the switching power supply 6 is completed, the control device 5 stops supplying power to the switching power supply 6 and the corresponding two electromagnets 43, and the switching power supply 6 can be taken out from the installation slot 13 in the horizontal direction, making the disassembly and assembly process of the switching power supply 6 more convenient.

[0089] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
