Description

Technical Field

[0001] The utility model relates to the technical field of flexible connection aging lines, and particularly relates to a flexible connection aging line for capacitors of different specifications. Background Technique

[0002] During the production and use of capacitors, aging tests are required to examine the performance changes under long-term working conditions. The aging test mainly simulates the use of capacitors in the actual working environment. By applying certain voltage and temperature conditions, the performance changes of capacitors are observed, including changes in capacitance, changes in loss tangent value, changes in leakage current, etc., and a flexible connection aging line is used to connect between the capacitor and the test equipment;

[0003] Currently, most of the existing flexible connection aging lines are generally designed according to capacitors of a certain specific specification. When encountering capacitors with different sizes or pin spacings, it is easy to cause the aging line to be incompatible with the capacitor, resulting in unstable connection, thus affecting the aging test. In addition, the shapes of capacitors are diverse, making the aging line inapplicable to capacitors of different shapes. For capacitors of different specifications, the aging line needs to be frequently replaced or adjusted, resulting in a relatively complex connection operation for the capacitor and being inconvenient for connection. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flexible connection aging line for capacitors of different specifications to solve the above deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A flexible connection aging line for capacitors of different specifications, including a wire, a connection clip, and a resistor. The wire includes a first wire and a second wire. There is a connecting piece between the connection clip and the resistor. The resistor is arranged between the connection clip and the wire. The connection clip includes a main clip and a sub-clip. A first connection block is connected to the inner side wall of the main clip. A second connection block elastically hinged to the first connection block is connected to the inner side wall of the sub-clip. One end of the connecting piece is welded to the end of the sub-clip. The lead of the resistor is welded to the end of the connecting piece away from the sub-clip. A serrated groove is formed at the clamping end of the connection clip, which enhances the frictional force between the connection clip and the capacitor, ensures the connection stability, enhances the reliability after connection, and avoids the occurrence of test errors due to poor contact. An insulating sleeve is sleeved on the end of the main clip. The wire is a flexible wire, which has good flexibility itself and can be adjusted according to the specific position of the capacitor, making the connection more simple and fast. And because the flexible wire has good flexibility and durability, it can reduce the wear caused by frequent plugging and unplugging and extend the service life of the aging line.

[0006] Through the above technical solution:

[0007] When connecting, manually pinch the ends of the main clamp and the auxiliary clamp toward the middle to open the clamping end of the connecting clamp, then place the connecting end outside the connecting end of the capacitor, and finally release the ends of the main clamp and the auxiliary clamp to connect the clamping end of the connecting clamp to the connecting end of the capacitor. The capacitor can be quickly connected and can also be quickly connected to capacitors of different specifications. It is suitable for capacitors of different sizes, shapes and pin spacings. There is no need to design connecting wires separately for each specification of capacitor. When performing aging tests on capacitors of different specifications, there is no need to shut down for a long time to replace the connecting wires, which reduces the downtime of the equipment, saves the time for replacing the connecting wires, and improves the versatility and flexibility of the use of the aging line.

[0008] Preferably, a connection component is provided at the connection point between the resistor and the wire, and the connection component includes a connection shell connected to one end of the resistor, and a connection terminal is connected in a reserved slot of the connection shell.

[0009] Preferably, a connecting plug is inserted into the connection of the connecting terminal, one end of the connecting plug away from the connecting terminal is connected to the end of the wire, and the connecting terminal is provided with a fastening screw for fastening the connecting plug after being inserted.

[0010] Preferably, a cover plate is hingedly connected to the opening of the front surface wall of the connecting shell, a screw is threadedly connected to the cover plate, and a screw groove matched with the screw is formed on the inner wall of the connecting shell.

[0011] Through the above technical solution:

[0012] When the wire is damaged, first take the screwing tool to unscrew the screw from the screw groove, then pry the cover plate outward to open the connection shell, then loosen the fastening screw, and finally pull the wire and unplug the connection plug from the connection terminal. This operation can quickly remove the worn wire and replace it with a new one by performing the above operation in reverse. This solves the problem that the existing welding connection requires special tools during disassembly and assembly, making it difficult to replace the wire, enhances the speed of wire replacement, and also prevents the use of welding connection due to the generation of toxic gases during welding, which may cause harm to the operator's body, thereby improving the safety of maintenance of aging wires.

[0013] In addition, the connecting terminal is connected to a first wire and a second wire, and the other ends of the first wire and the second wire are respectively connected to another connecting clip, so that the number of corresponding connecting clips can be selected according to capacitors of different diameters, thereby avoiding the problem of a fixed number of aging ovens due to the number of connecting clips being a fixed value, and solving the problem of aging efficiency of different diameters and different numbers.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. By setting up connection clips, the aging line is composed of wires, resistors and connection clips, and the connection clips are driven to close by springs. During use, it can be quickly connected to capacitors of different specifications, applicable to capacitors of different sizes, shapes and pin spacings. There is no need to separately design connecting wires for each specification of capacitor. When conducting aging tests on capacitors of different specifications, there is no need to shut down the equipment for a long time to replace the connecting wires, reducing the downtime of the equipment, saving the time for replacing the connecting wires, and improving the versatility and flexibility of the aging line. In addition, two wires are connected to one end of the connection clip, and the two wires are respectively connected to another connection clip, enabling it to select the corresponding number of connection clips according to capacitors of different diameters, avoiding the problem of a fixed number of aging ovens caused by the fixed number of connection clips, solving the problem of different aging efficiencies for different diameters and different quantities. Moreover, the clamping end of the connection clip is provided with serrated textures, which can enhance the friction between the connection clip and the capacitor, ensuring connection stability, enhancing the reliability after connection, and avoiding test errors caused by poor contact.

[0016] 2. By setting up connection components, during the maintenance of the aging line, the disassembly and assembly of the wires can be quickly achieved, solving the problem that the existing welding connection method requires special tools for disassembly and assembly, making it difficult to replace the wires. It effectively shortens the time for wire replacement, enhances the quickness of wire replacement, and also prevents the generation of toxic gases during the welding process in the case of welding connection, which may cause harm to the operator's body, improving the safety of aging line maintenance.
