Description

Technical Field

[0001] The utility model belongs to the technical field of jigs, and particularly relates to a high-temperature resistant test jig for ceramic capacitors. Background Art

[0002] The high-temperature resistant test of ceramic capacitors is a key step to evaluate their performance and reliability in a high-temperature environment. Generally, the capacitors need to be exposed to a high-temperature environment, usually in the temperature range of 125°C to 200°C for 500 hours to 1000 hours. During the heating period, samples need to be taken out regularly for electrical performance tests (such as once every 100 hours). After the test, the room temperature is restored for the final electrical performance test. When conducting the test, jigs are required to clamp and fix the capacitors. However, the existing jigs are difficult to conveniently increase or decrease the number of jigs and adjust the positions according to the number and size of the capacitors to be tested, resulting in insufficient usability.

Specific embodiments

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0026] As Figures 1-5 shown, a high-temperature test fixture for a ceramic capacitor includes a base 1, a bracket 2 is installed on the top of the base 1, a chute 3 runs through between the front and back of the bracket 2, a first adjustment through slot 4 runs through between the top of the chute 3 and the top of the bracket 2, a first slider 5 is slidably installed inside the chute 3, adjustment slide rails 6 are provided on both the front and back sides of the first slider 5, a second slider 7 is slidably installed inside the adjustment slide rails 6, a second adjustment through slot 8 runs through the side plate of the adjustment slide rail 6, a fixed clamping plate 10 is fixedly installed on the second slider 7, a sliding rod 11 is slidably inserted into the fixed clamping plate 10, a movable clamping plate 14 is provided at the other end of the sliding rod 11, a spring 13 is sleeved on the outside of the sliding rod 11, one end of the chute 3 runs through the side wall of the bracket 2, and the top of the adjustment slide rail 6 is in a through state.

[0027] When the device is in use, the position of the first slider 5, the adjustment slide rail 6, and the second slider 7 are adjusted steplessly according to the size of the capacitor to be detected. Since one end of the chute 3 penetrates the side wall of the bracket 2 and the top of the adjustment slide rail 6 is in a penetrating form, the number of the first sliders 5, the adjustment slide rail 6, and the second sliders 7 can also be freely and conveniently increased or decreased according to the size and number of the capacitors to be detected, so as to meet the clamping requirements of capacitors of different sizes and numbers. By clamping the capacitors on both sides of the bracket 2, the device can be provided with heating devices on both the front and rear sides, and the capacitors located on the front and rear sides of the device can be heated simultaneously from the front and rear sides of the device, improving the test efficiency.

[0028] Bolt holes are provided on the top of the first slider 5 and the side surface of the second slider 7, and locking bolts 9 are threadedly connected thereto.

[0029] The locking bolt 9 is used to lock and fix the first slider 5 and the second slider 7.

[0030] A knob 16 is provided at the end of the locking bolt 9.

[0031] The knob 16 is used to facilitate the manual rotation of the locking bolt 9.

[0032] A pull ring 12 is provided at one end of the slide bar 11.

[0033] The pull ring 12 is used to facilitate the pulling of the slide bar 11.

[0034] Arc-shaped grooves 15 are provided on the side surfaces of the fixed clamping plate 10 and the movable clamping plate 14 facing each other.

[0035] The arc-shaped grooves 15 are used to accommodate and clamp the electrodes of the capacitor, preventing the capacitor from being skewed.

[0036] Working principle and usage process of the present utility model: When this device is in use, the position of the first slider 5, the adjusting slide rail 6, and the second slider 7 are adjusted steplessly according to the size of the capacitor to be detected. Since one end of the chute 3 penetrates the side wall of the bracket 2 and the top of the adjusting slide rail 6 is in a penetrating form, the number of the first sliders 5, the adjusting slide rail 6, and the second sliders 7 can also be freely and conveniently increased or decreased according to the size and quantity of the capacitors to be detected, so as to meet the clamping requirements of capacitors of different sizes and quantities. By tightening the locking bolt 9, the first slider 5 and the second slider 7 can be locked to complete the adjustment. Subsequently, the pull ring 12 can be pulled to drive the movable clamping plate 14 to move through the slide rod 11, and the spring 13 is compressed by the movable clamping plate 14. Subsequently, the electrodes of the capacitor can be placed between the fixed clamping plate 10 and the movable clamping plate 14. Then, the pull ring 12 is released, and under the resilience of the spring 13, the movable clamping plate 14 resets to cooperate with the fixed clamping plate 10 to clamp and fix the electrodes of the capacitor. Subsequently, the high-temperature test can be started. By clamping the capacitors on both sides of the bracket 2, heating devices can be arranged on both the front and rear sides of this device, and the capacitors located on the front and rear sides of this device can be heated simultaneously from the front and rear sides of this device, improving the test efficiency.

[0038] Specific examples are used in this article to elaborate on the principle and implementation mode of the present utility model. The description of the above examples is only used to help understand the method and its core idea of the present utility model. The above is only the preferred implementation mode of the present utility model. It should be pointed out that due to the limited nature of written expression, objectively there are infinite specific structures.
