Description

Technical Field

[0001] The utility model relates to the technical field of capacitor discharge, in particular to a discharge device for capacitor aging testing. Background Art

[0002] With the development of society, people have higher and higher requirements for capacitors. In order to improve the shipment quality of capacitors, a discharge device is needed to perform aging tests on capacitors before leaving the factory.

[0003] In the patent application with the authorization publication number CN218216756U and the authorization publication date 2023-01-03, entitled "A Supercapacitor Discharge Device", when the staff needs to discharge the capacitor body, they first rotate the first screw cover by hand to drive the rotating rod to rotate so that the card strip is parallel to the inside of the card slot, and then pull out the installation box through the limit of the slide plate. At this time, the staff will place the capacitor body on the inner side of the installation slot according to the number of capacitor bodies to be installed. After the placement is completed, the installation box is pushed back to the inside of the insulating box, and then the first screw cover is twisted to engage the card strip with the card slot to fix the installation box. The staff clamps the electrical appliance with an electrode clamp to discharge the capacitor body;

[0004] During the actual use of the above-mentioned device, the capacitor body is placed in the installation slot for subsequent discharge operations. However, the installation slot is not suitable for capacitor bodies of different sizes, which causes the capacitor body to easily tilt in the installation slot, affecting the normal connection between the capacitor body and the positive and negative terminal connection seats. At the same time, it is necessary to rotate the first screw cover to achieve disassembly and assembly, which is inconvenient to use.

[0005] Therefore, we propose a discharge device for capacitor aging test in order to solve the above problems. Utility Model Content

[0007] The purpose of the present utility model is to provide a discharge device for capacitor aging testing to solve the problems in the current market raised by the above background technology.

[0008] 2. Technical solution:

[0009] To achieve the above-mentioned object, the present invention provides the following technical solution: a discharge device for capacitor aging testing, comprising an insulating housing, a positive electrode connection seat fixedly mounted on the lower end of the interior of the insulating housing, a negative electrode connection seat movably mounted on the upper end of the interior of the insulating housing, and the left ends of the positive electrode connection seat and the negative electrode connection seat are both connected to electrode clips on the outside of the insulating housing via wires;

[0010] A movable seat is slidably mounted on the interior of the insulating housing, and placement holes are opened at equal intervals on the interior of the movable seat. A limiting mechanism is installed on the inner wall of the placement hole, and the limiting mechanism is used to fix the capacitor;

[0011] A sealing plate is fixedly installed on the right end of the movable seat, and a roller is installed on the lower end of the sealing plate, and a handle is fixedly installed on the side of the upper end of the sealing plate away from the insulating shell, and a connecting block is fixedly installed on the side of the upper end of the sealing plate close to the insulating shell, and a positioning block is slidingly installed in the interior of the connecting block, and the positioning block is used to fix the sealing plate to the end of the insulating shell, and an unlocking component is installed between the positioning block and the handle, and the unlocking component is used to pull the positioning block to move.

[0012] Furthermore, a rotating rod is installed on the upper end bearing of the negative electrode connecting seat, and the rotating rod is threadedly connected to the insulating shell.

[0013] Through the above technical solution, after the rotating rod is rotated, the negative electrode connecting seat can be driven to move downward by utilizing the threaded connection.

[0014] Furthermore, the limiting mechanism includes a movable column slidably mounted on the inner wall of the placement hole, a first spring is connected between the movable column and the movable seat, and a clamp is slidably mounted inside the movable column, and a second spring is connected between the clamp and the movable column.

[0015] Through the above technical solution, the clamping plate can be tightly attached to the surface of the capacitor under the action of the second spring, thereby limiting the capacitor and preventing it from deflecting.

[0016] Furthermore, the lower end of the clamping plate is in an "L"-shaped structure, and the upper end of the clamping plate is in an arc-shaped structure design, and the clamping plates are distributed at equal angles with respect to the placement holes.

[0017] The above technical solution makes it easier for the capacitor to be inserted into the placement hole.

[0018] Furthermore, the positioning block is arranged in a trapezoidal shape, and a fourth spring is connected between the positioning block and the connecting block.

[0019] Through the above technical solution, the positioning block is extended into the interior of the insulating shell under the action of the fourth spring to achieve connection.

[0020] Furthermore, the unlocking assembly includes a pull plate slidably mounted inside the handle, a pull rope is connected between the pull plate and the positioning block, and a third spring is connected between the pull plate and the handle.

[0021] Through the above technical solution, the positioning block can be retracted into the connecting block by pulling the pull plate and the pull rope.

[0022] 3.Beneficial effects:

[0023] Compared with the prior art, the present invention provides a discharge device for capacitor aging testing. By setting a limit mechanism, the discharge device can be applied to capacitors of different sizes, thus preventing capacitor deflection from affecting the discharge operation and facilitating disassembly and assembly. The specific contents are as follows:

[0024] After the movable seat is pulled out from the insulating housing, the capacitors are placed in the placement holes one by one. During the placement process, the upper arc-shaped clamping plate facilitates the capacitor to extend between the multiple clamping plates. The clamping plate uses the elasticity of the second spring to fit tightly against the surface of the capacitor, positioning the capacitor and preventing the capacitor from deflecting in the placement hole, thereby ensuring subsequent normal discharge operation.

[0025] When the movable seat needs to be pulled out of the insulating shell, the pull plate is pressed on the handle, and the pull plate uses the pull rope to pull the positioning block back to the inside of the connecting block, thereby releasing the connection between the insulating shell and the sealing plate. The movable seat can then be pulled by the handle, and the sealing plate can use rollers to improve the movement stability during the pulling process. When installing, the movable seat is directly pushed into the inside of the insulating shell. After moving to the appropriate position, the positioning block can be extended into the interior of the insulating shell under the action of the fourth spring without obstruction, thereby realizing quick connection.
