Description

Technical Field

[0001] The utility model relates to the technical field of capacitor aging inspection, and more specifically, to an aging inspection device for capacitor production. Background Art

[0002] Two conductors close to each other, with a non-conductive insulating medium in between, form a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering.

[0003] After the production is completed, the capacitor needs to be aged and inspected before it can be shipped. The aging inspection of the capacitor mainly detects the performance such as capacity, loss, withstand voltage, leakage current, etc. to ensure that it meets the specification requirements. During the aging inspection, the batch of capacitors needs to be placed on the aging board. As described in the automatic aging machine board for aging and testing capacitors with the publication number CN211927976U, the inner wall of the capacitor accommodating groove is symmetrically opened with docking grooves, and a docking block is inserted in the docking groove. The docking block is against the capacitor head, and a docking spring is arranged between the docking block and the docking groove. When the capacitor is inserted into the capacitor accommodating groove, the docking spring is compressed and applies a reverse elastic force to the docking block, so that the capacitor is fixedly clamped between the two docking blocks.

[0004] However, in actual use, the above structure relies on the elastic deformation ability of the spring to clamp the batch of capacitors. Therefore, when putting in and taking out each capacitor, the hand needs to exert force to overcome the force of the spring, which is laborious and troublesome for the user. Utility Model Content

[0025] A movable block 18 is slidably sleeved on the push rod 9 at the side of the locking block 13 away from the second inclined surface 17. The outer diameter of the movable block 18 is consistent with the outer diameter of the locking block 13, and third inclined surfaces 19 are provided on both sides of the movable block 18. A groove 20 for accommodating the movable block 18 is opened in the locking block 13, and a second return spring 21 is fixedly abutted between the locking block 13 and the movable block 18. The elastic deformation capacity of the second return spring 21 is smaller than the elastic deformation capacity of the elastic telescopic rod 15. A second limit block 22 is fixedly sleeved on the side of the movable block 18 away from the locking block 13.

[0026] Additionally, the elastic telescopic rod 15 includes a fixed rod 151 and a sliding rod 152 slidably sleeved on the fixed rod 151, one end of the fixed rod 151 is fixed to the inner wall of the accommodating groove 14, a third return spring 153 is wound around the fixed rod 151, two ends of the third return spring 153 respectively abut against the inner wall of the accommodating groove 14 and the outer wall of the sliding rod 152, and the first inclined surface 16 is set on the sliding rod 152.

[0027] One end of the push rod 9 and the connecting rod 3 both extend to the outside of the limiting plate 1 and are fixedly provided with an annular push plate 23. The raised annular push plate 23 is convenient for users to grasp and perform push and pull operations.

[0028] The clamping plate 6 is arranged in a V-shape, which can provide better stability and prevent the round capacitor from slipping, thereby ensuring that the capacitor remains stable during the clamping process. A rubber pad 24 is arranged on the inner wall of the clamping plate 6. The rubber pad 24 can increase the friction between the clamping surface and the capacitor, thereby improving the clamping stability. On the other hand, it can play a buffering and protective role to avoid damage or scratches to the capacitor surface during the clamping process.

[0029] Working principle: In order to facilitate the taking and placing of capacitors, when using, a batch of capacitors are placed in the capacitor accommodating groove 2 respectively, and then the user pushes the connecting rod 3 inward, and the connecting rod 3 drives the connecting block 4 to move, and the clamping plate 6 on one side of the connecting block 4 moves close to the capacitor. At the same time, the driving block 7 fixed on the other side of the connecting block 4 also moves synchronously, and drives the push rod 9 to move as a whole through the first limit block 10, so that the locking block 13 moves to a position that contacts the elastic telescopic rod 15, and then through the cooperation of the first inclined surface 16 and the second inclined surface 17, the locking block 13 continues to move and pushes the elastic telescopic rod 15 to shrink, and after the locking block 13 passes over the elastic telescopic rod 15, the elastic telescopic rod 15 elastically resets and contacts the locking block 13 to limit it, and it cannot move in the opposite direction by itself. At this time, the clamping plate 6 just presses the capacitor against the side wall of the capacitor accommodating groove 2 to fix it, and the fixing effect on the capacitor can still be maintained after letting go;

[0030] When the capacitor needs to be removed, the push rod 9 is first pushed inward, and the push rod 9 drives the locking block 13 and the movable block 18 to continue to move forward. When the movable block 18 contacts the elastic telescopic rod 15, due to the action of the second limit block 22, the third inclined surface 19 on the front side of the movable block 18 can push the elastic telescopic rod 15 to retract again, until the movable block 18 passes over the elastic telescopic rod 15, and the elastic telescopic rod 15 resumes the extended state. In the process of pushing the push rod 9, the first return spring 12 is squeezed by the first limit block 10 in a contracted state. Therefore, when the push rod 9 is released, the push rod 9 can be driven by the elastic recovery action of the first return spring 12 to move in the opposite direction and reset.

[0031] During the movement, since the elastic deformation capacity of the second return spring 21 is smaller than that of the third return spring 153, the elastic telescopic rod 15 will remain in the extended state, thereby overcoming the force of the second return spring 21 to push the movable block 18 to move along the push rod 9 in the direction close to the locking block 13. The second return spring 21 is compressed as the movable block 18 moves until the movable block 18 enters the groove 20 of the locking block 13. The movable block 18 is blocked by the locking block 13, so that the push rod 9 continues to move and can push the elastic telescopic rod 15 to retract again through the third inclined surface 19 on the other side of the movable block 18, and maintain this retracted state until it passes over the locking block 13. Then, the locking block 13 is no longer blocked by the elastic telescopic rod 15, and the connecting rod 3 can be pulled freely. Pulling the connecting rod 3 outward can drive the clamping plate 6 to release the fixation of the capacitor.

[0032] The utility model provides a connecting rod 3 and a push rod 9, etc., which can drive the whole row of clamping plates 6 to move synchronously through a simple push-pull operation, thereby effectively fixing and releasing the whole row of capacitors, making it easier and more labor-saving to use, thereby improving the efficiency of the capacitor aging inspection process.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
