Abstract
Description
Technical Field
[0001] This application relates to the field of contactor temperature rise testing, and in particular to a highly applicable contactor temperature rise testing bench. Background Technology
[0002] A contactor temperature rise test bench is a device specifically designed to test the temperature rise of a contactor during operation. It is primarily used to detect temperature changes in contactors under simulated real-world operating conditions to ensure their safety and reliability during long-term operation.
[0003] The contactor temperature rise test bench simulates the actual working environment of the contactor by applying a certain current load to the contactor, causing the conductors inside the contactor to heat up. Then, the temperature of the conductors is monitored by sensors after long-term operation and stabilized. The temperature rise of the contactor is calculated by comparing it with the ambient temperature. Finally, the temperature rise is compared with the product standard qualified temperature rise to determine whether the temperature rise of the contactor product is qualified.
[0004] However, in existing contactor temperature rise test benches, small contactors are typically connected by sliding fasteners to the guide rails, allowing multiple small contactors to slide together on the guide rails. When installing larger contactors, a single guide rail is not suitable for some large contactors, and there is no convenient installation method for large contactors. Therefore, a contactor temperature rise test bench is needed that can facilitate the installation of both small and large contactors, thereby improving production efficiency. Utility Model Content
[0005] To provide a contactor temperature rise test bench that is convenient for both small and large contactors, a highly applicable test bench is provided.
[0006] The above-mentioned objective of this application is achieved through the following technical solution:
[0007] A highly applicable contactor temperature rise test bench includes a body, a fixed plate mounted inside the body, a guide rail mounted on the fixed plate, and a tooling assembly. The tooling assembly includes a first tooling strip and a second tooling strip, which are parallel to each other. The first tooling strip is fixedly connected to the fixed plate. The fixed plate has a sliding groove, and the second tooling strip is slidably connected to the sliding groove, moving towards or away from the first tooling strip along the sliding groove. The first tooling strip has a set of first sliding grooves, and the second tooling strip has a set of second sliding grooves, which are parallel to each other. Two first studs are mounted on the first tooling strip, each slidably connected to a set of first sliding grooves. Two second studs are mounted on the second tooling strip, each slidably connected to a set of second sliding grooves.
[0008] By adopting the above technical solution, small contactors can be fastened to the guide rail; the second tooling strip can adjust the distance between the first tooling strip and the second tooling strip through the sliding groove; the first stud can slide in the first sliding groove, thereby changing the distance between the two first studs; the second stud can slide in the second sliding groove, thereby changing the distance between the two second studs. This allows for the installation of contactors of more different specifications, facilitating the installation of both small and large contactors, enhancing the applicability of the equipment, and improving production efficiency.
[0009] Optionally, the tooling assembly further includes an abutment tube, which is parallel to the second tooling strip and abuts against the second tooling strip on the side of the abutment tube facing the second tooling strip.
[0010] By adopting the above technical solution, an additional abutment pipe is added. When the second tooling strip becomes loose during sliding adjustment in the sliding groove, the second tooling strip will fall away from the first tooling strip. The abutment pipe can support the second tooling strip, reducing the likelihood of it falling and being damaged, and reducing the frequency of maintenance.
[0011] Optionally, the number of sliding grooves is two, and the two sliding grooves are located at both ends of the second tooling strip.
[0012] By adopting the above technical solution, the stability of the second tooling strip structure can be significantly improved due to the two support points, reducing tilting or swaying caused by uneven force on one side, and ensuring the smooth operation of the tooling strip during the sliding process.
[0013] Optionally, a first adjusting tube and a second adjusting tube are installed inside the machine body. The first adjusting tube and the second adjusting tube are relatively parallel, and the two sides of the fixing plate are slidably connected to the first adjusting tube and the second adjusting tube, respectively.
[0014] By adopting the above technical solution, the height of the fixing plate can be adjusted up and down on the first adjusting tube and the second adjusting tube, so that the fixing plate can be adjusted to a suitable operating height to suit different operators' heights and improve the assembly efficiency of the contactor.
[0015] Optionally, it also includes a pin, one end of which is located inside the first adjusting tube and is fitted with an abutment piece. At least two limiting blocks are installed on the inner wall of the first adjusting tube. The limiting blocks have a insertion groove in the middle that runs along the installation direction of the first adjusting tube. The abutment piece abuts against the limiting block, and the thickness of the abutment piece in the direction parallel to the limiting block is less than the distance between the two groove walls of the insertion groove.
[0016] By adopting the above technical solution, when the height of the fixed plate needs to be adjusted, the pin is rotated so that the abutment piece is perpendicular to the limit block. The vertical abutment piece passes through the insertion groove in the middle of the limit block, and then the fixed plate can be adjusted up and down. When the fixed plate reaches the appropriate operating height, the pin is rotated so that the abutment piece is perpendicular to the limit block and abuts against the limit block. This allows for quick adjustment and fixation of the fixed plate, improving the adjustment efficiency of the fixed plate.
[0017] Optionally, a limiting block parallel to the first adjusting tube is installed inside the second adjusting tube, and a insertion groove along the installation direction of the second adjusting tube is opened in the middle of the limiting block. There are two pins, one end of the other pin is located inside the second adjusting tube and is equipped with an abutment piece, which abuts against the limiting block.
[0018] By adopting the above technical solution, the second adjusting tube is provided with the same structure as the first adjusting tube, so that both sides of the fixing plate can be supported by the limiting block in the first and second adjusting tubes, thereby improving the load-bearing capacity of the fixing plate and improving the stability of the fixing plate in the adjustment of the first and second adjusting tubes.
[0019] Optionally, the pin includes a connecting rod, one end of which is fixedly connected to the abutment piece, and the other end of the connecting rod away from the abutment piece is fixedly connected to a rotating piece, which is perpendicular to the abutment piece.
[0020] By adopting the above technical solution, when the rotating link drives the abutment plate to rotate, the rotation state of the abutment plate cannot be directly observed. By adding a rotating plate, the rotation state of the abutment plate can be obtained through the rotation state of the rotating plate, making the rotation of the abutment plate more convenient and improving the efficiency of adjusting the height of the fixing plate.
[0021] Optionally, a hook is also installed inside the machine body, and the hook is located above the fixing plate.
[0022] By adopting the above technical solution, the temperature of the contacts will rise after the contactor is connected to the current. If the wires and sensor wires inside the machine are too messy and come into contact with the contactor, the high temperature will pose a safety hazard to the wires or sensor wires. Therefore, hooks are added to bind the wires and sensor wires, thereby improving the safety of the equipment.
[0023] In summary, this application has at least the following beneficial effects:
[0024] 1. Connect the small contactor to the guide rail by fastening it together. Pass the fixing holes at the four corners of the large contactor through the two first studs of the first tooling strip and the two second studs of the second tooling strip, respectively. Then screw the two first studs and the two second studs into the nuts to fix the large contactor. This method can facilitate the installation of both small and large contactors, thus improving its applicability.
[0025] 2. The height of the fixing plate can be adjusted on the first and second adjusting tubes via pins, thus accommodating people of different heights for contactor installation, making it easier for operators to install the contactor and improving its applicability. Attached Figure Description

[0031] The following section provides a more detailed description, in conjunction with the accompanying diagrams:
[0032] As attached Figure 1 and attached Figure 2 As shown, a contactor temperature rise test bench includes a body 1, a base cabinet 2, a pin 3, a tooling assembly 4, and a guide rail 5.
[0033] The upper surface of the body 1 is fixedly connected to the base cabinet 2. The body 1 includes a control door 11. One side of the control door 11 is hinged to the body 1 via a hinge. A transparent panel 111 is installed on the control door 11. After the control door 11 is closed, the real-time operation of the contactor inside the body 1 can be observed through the transparent panel 111. In case of contactor failure, an immediate response can be made, improving the safety performance of the equipment.
[0034] As attached Figure 2 and attached Figure 3 As shown, the first regulating pipe 12 and the second regulating pipe 13 are installed inside the body 1.
[0035] The first adjusting tube 12 is fixedly connected to the base cabinet 2 at one end, and the first adjusting tube 12 is perpendicular to the base cabinet 2. At least two limiting blocks 15 are installed inside the first adjusting tube 12, and the side walls of the limiting blocks 15 are fixedly connected to the inner wall of the first adjusting tube 12.
[0036] The end of the second adjusting tube 13 facing the base cabinet 2 is fixedly connected to the base cabinet 2, and the second adjusting tube 13 is perpendicular to the base cabinet 2. The second adjusting tube 13 is parallel to the first adjusting tube 12. A limiting block 15 parallel to the inside of the first adjusting tube 12 is installed inside the second adjusting tube 13, and the side walls of the limiting block 15 are fixedly connected to the inner wall of the second adjusting tube 13.
[0037] As attached Figure 3 and attached Figure 4 As shown, there are multiple limiting blocks 15. The number of limiting blocks 15 in the first adjusting tube 12 is equal to that in the second adjusting tube 13, and they are parallel. The middle part of the limiting block 15 has a through insertion groove 151 along the installation direction of the first adjusting tube 12 and the second adjusting tube 13.
[0038] As attached Figure 2 and attached Figure 3 As shown, a fixing plate 14 for mounting the contactor is installed inside the body 1. Both sides of the fixing plate 14 are slidably connected to the first adjusting pipe 12 and the second adjusting pipe 13. There are two sliding grooves 141 on the surface of the fixing plate 14, and they are located on both sides of the fixing plate 14 respectively.
[0039] The machine body 1 is also equipped with a hook 16, which is connected to the upper end of the second regulating tube 13. There are two hooks 16, which are used to harness the wires and sensor wires respectively, preventing the wires and sensor wires from coming into contact with the contactor and causing safety hazards, thus improving the safety performance of the equipment.
[0040] The guide rail 5 is located on the end of the fixed plate 14 facing away from the base cabinet 2 and is fixedly connected to the fixed plate 14, so that the small contactor can be engaged with the guide rail 5 to fix the position of the small contactor.
[0041] The tooling assembly 4 is located on the lower side of the guide rail 5. The tooling assembly 4 includes a first tooling strip 41, a second tooling strip 42, and an abutment pipe 43.
[0042] The first tooling strip 41 is long and narrow. It is located on the side of the guide rail 5 facing the base cabinet 2 and is parallel to the guide rail 5. It is fixedly connected to the fixing plate 14 and has two first sliding grooves 411 that pass through it. Both first sliding grooves 411 are parallel to the guide rail 5. The first tooling strip 41 also includes two first studs 412, which are slidably connected to the two first sliding grooves 411 respectively.
[0043] The second tooling strip 42 is long and narrow. It is located on the side of the guide rail 5 opposite to the first tooling strip 41. The second tooling strip 42 is parallel to the first tooling strip 41. The second tooling strip 42 is slidably connected in two sliding grooves 141, which can accommodate contactors of more specifications and sizes, thus improving its applicability.
[0044] The second tooling strip 42 includes two fasteners 421, both of which are cylindrical. The two fasteners 421 are located at both ends of the second tooling strip 42. One end of the two fasteners 421 passes through the second tooling strip 42 and is threadedly connected to two nuts on the back side of the fixing plate 14. The other end of the fasteners 421 is located on the side of the second tooling strip 42 facing away from the fixing plate 14.
[0045] The second tooling strip 42 has two second sliding grooves 422 that pass through it. The second tooling strip 42 also includes two second studs 423, which are slidably connected to the two second sliding grooves 422 respectively.
[0046] The abutment tube 43 is located on the side of the second tooling strip 42 facing away from the first tooling strip 41, and the abutment tube 43 is fixedly connected to the fixing plate 14. The abutment tube 43 is parallel to the second tooling strip 42, and the side of the abutment tube 43 facing the second tooling strip 42 abuts against the second tooling strip 42. When the second tooling strip 42 becomes loose during sliding adjustment in the sliding groove 141, the second tooling strip 42 will fall away from the first tooling strip 41. The abutment tube 43 can support the second tooling strip 42, reducing the risk of the second tooling strip 42 falling and being damaged.
[0047] As attached Figure 3 and attached Figure 4 As shown, there are two pins 3, which are located at both ends of the abutment tube 43. Each pin 3 includes an abutment piece 31, a connecting rod 32, and a rotating piece 33.
[0048] The connecting rod 32 is cylindrical in shape, and there are two connecting rods 32. One end of each connecting rod 32 passes through the abutment tube 43 and the fixing plate 14 in sequence, and is inserted into the first adjusting tube 12 and the second adjusting tube 13 respectively. The other end of each connecting rod 32 is located on the side of the abutment tube 43 facing away from the fixing plate 14.
[0049] There are two abutment pieces 31. One abutment piece 31 is fixedly connected to the connecting rod 32 inserted into the first adjusting tube 12, and its length and thickness are both less than the distance between the side walls of the first adjusting tube 12. The other abutment piece 31 is fixedly connected to the connecting rod 32 inserted into the second adjusting tube 13, and its length and thickness are both less than the distance between the side walls of the second adjusting tube 13. When the two connecting rods 32 are rotated, the two connecting rods 32 respectively drive the two abutment pieces 31 to rotate, so that the two abutment pieces 31 rotate in the first adjusting tube 12 and the second adjusting tube 13 respectively.
[0050] When the abutment piece 31 rotates to be perpendicular to the limiting block 15, the thickness of the abutment piece 31 in the direction parallel to the limiting block 15 is less than the distance between the two groove walls of the insertion groove 151, so that the abutment piece 31 can pass through the insertion groove 151 from top to bottom.
[0051] There are two rotating pieces 33. The two rotating pieces 33 are fixedly connected to the ends of the two connecting rods 32 away from the abutment piece 31, and the rotating pieces 33 are perpendicular to the abutment piece 31. The rotation state of the abutment piece 31 can be obtained by the rotation state of the rotating pieces 33, making the rotation of the pin 3 more convenient and improving the efficiency of the height adjustment of the fixing plate 14.
[0052] The effect of this embodiment:
[0053] When installing small contactors, simply engage the small contactor with the guide rail 5. When installing large contactors, the second tooling strip 42 can adjust the distance between the first tooling strip 41 and the second tooling strip 42 via the sliding groove 141. The first stud 412 can slide within the first sliding groove 411, thereby changing the distance between the two first studs 412. The second stud 423 can slide within the second sliding groove 422, thereby changing the distance between the two second studs 423. This allows for the installation of more large contactors, enabling the simultaneous installation of both small and large contactors, enhancing the applicability of the equipment and improving production efficiency.
[0054] Meanwhile, the height of the fixing plate 14 can be adjusted by the pin 3 in the first adjusting tube 12 and the second adjusting tube 13, so that the height of the fixing plate 14 can be suitable for the height of different operators, and the fixing plate 14 is located at a suitable height for installing the contactor, thereby improving the efficiency of installing the contactor.
[0055] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
