[0002] Capacitor testing can clearly and intuitively reveal the various electrical properties of the capacitor. During the test, the operator needs to contact the wire connected to the test device to the capacitor. First, for capacitors with larger volumes, it is inconvenient to transfer. Second, the circuit is connected by winding or contacting. Since the contact between the wire and the wire connection column is poor, it is easy to affect the test results. Utility Model Content
[0003] The utility model provides a column capacitor testing device to solve the above-mentioned deficiencies in the prior art, can automatically carry out material loading during capacitor testing, and can also improve the contact effect during testing, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:
[0005] A cylindrical capacitor testing device comprises a bottom plate, an outer support plate is arranged at one end of the bottom plate, an end plate is arranged at the outer end of the outer support plate, a cylinder is installed on the end plate, and the arrangement of the cylinder can automatically push the capacitor to move, so as to achieve the purpose of automatic loading. A vertical plate is arranged at the other end of the bottom plate, two pairs of guide holes are opened at the upper end of the vertical plate, movable rods are inserted into the guide holes, an inner plate is arranged at the inner end of each pair of movable rods, a connecting plate is arranged at the inner plate, a connecting block of the connecting plate is arranged, an inner pressure plate is arranged at the outer end of each pair of movable rods, an inclined hole is opened at the inner pressure plate, the outer end of the inclined hole is inclined inward, a movable column is arranged in the inclined hole, a connecting rod is arranged at the lower end of the movable column, an outward push horizontal plate is arranged at the lower end of the connecting rod, a convex plate is arranged on the outward push horizontal plate, a spring pin is inserted on the convex plate, the inner end of the spring pin is arranged on the vertical plate, a spring is sleeved at the outer end of the spring pin, a T-shaped plate is sleeved on the spring pin, the outer end of the T-shaped plate acts on the convex plate, and the inner end of the T-shaped plate is inserted into the vertical plate. And when the capacitor moves, the capacitor can push the inner end of the T-plate, thereby causing the T-plate to move outward, and the spring is also compressed. At the same time, when the T-plate moves outward, the movable column will move, and when the movable column moves, it will act on the inclined hole, thereby causing the connecting block to move outward, and connecting the conductive sheet on the connecting block to the capacitor's terminal. When the test is completed, when the capacitor is moved outward, the connecting block and the capacitor's terminal will be disconnected, thereby improving the circuit connection stability of the test.
[0006] Furthermore, in order to push the capacitor to move inward, a pair of limiting plates are provided on the bottom plate.
[0007] Furthermore, in order to limit and guide the movement of the connecting rod, a middle plate is provided on the connecting rod, a guide plate is passed through the middle plate, and the inner end of the guide plate is installed on the vertical plate.
[0008] Furthermore, in order to prevent the inner end of the T-shaped plate from causing damage or deformation to the capacitor when the capacitor is moved inward, an arc-shaped plate is provided at the inner end of the T-shaped plate.
[0009] Furthermore, in order to automatically perform the capacitor pulling operation, a limit ring is provided at the inner end of the cylinder.
