Description

Technical Field

[0001] The utility model relates to the technical field of capacitance detection, in particular to a capacitance detection fixture. Background Art

[0002] Capacitance, also known as "capacitance," refers to the amount of free charge stored under a given potential difference. Generally speaking, charges move under force in an electric field. When there is a medium between conductors, the movement of charges is hindered, causing charges to accumulate on the conductors, resulting in the accumulation of charges. The amount of stored charge is called capacitance.

[0003] Traditional capacitance detection fixtures generally use a bidirectional screw to drive two clamping blocks. Rotating the bidirectional screw moves the two clamping blocks to clamp the capacitor.

[0004] This type of capacitance detection fixture has the following disadvantages: the lead screw needs to be rotated repeatedly when clamping and releasing, which is laborious and troublesome to operate. Therefore, we propose a capacitance detection fixture. Utility Model Content

The upper end of the distribution plate 6 is provided with evenly distributed distribution grooves 16. A fixed plate 15 is fixedly connected between the two sliding blocks 10. The lower end of the fixed plate 15 The surface is provided with evenly distributed fixing grooves 22, the fixing plate 15 corresponds to the upper and lower positions of the arrangement plate 6, the rear end of the bottom plate 1 is provided with a positioning block 17, the upper end of the positioning block 17 is provided with a slot 2, the rear ends of the two slide posts 8 are fixedly connected with a fixing block 21 through the mounting plate, the middle part of the fixing block 21 is provided with an insert 20, the slot 2 is plugged with the insert 20, the middle part of the positioning block 17 is provided with a slide groove, the slide groove is slidably connected to the limiting block 3, the outer surface of the insert 20 is provided with a limiting groove 19, the limiting block 3 is installed in conjunction with the limiting groove 19, the upper middle part of the bottom plate 1 is provided with a symmetrical slide rail 4, the two slide rails 4 are slidably connected with a slider 5, the upper end of the slider 5 is fixedly connected with the arrangement plate 6, the arrangement The rear end of the plate 6 is fixedly connected to the connecting block 7, and the rear end of the connecting block 7 is provided with a magnet 18. The middle part of the front side of the positioning block 17 is also provided with a magnet 18. The two magnets 18 are arranged in coordination. The upper end of the bottom plate 1 and the lower end of the sliding block 10 are both provided with a spring 9. The spring 9 is sleeved on the outer surface of the sliding column 8. The rear end of the fixed block 21 is threadedly connected with a locking screw 23. The locking screw 23 is installed in coordination with the outer surface of the insertion strip 20.

[0024] The working principle of a capacitance detection fixture provided by the present invention is as follows: when capacitance detection is required, the capacitance detection staff needs to first place the capacitor in the arrangement slot 16 at the upper end of the arrangement plate 6, and then loosen the locking screw 23 to adjust the length of the insertion strip 20 according to the length of the capacitor. After the adjustment is completed, tighten the locking screw 23, and then push the arrangement slot 16 backward until the two magnets 18 are attracted to each other. Then hold the pull rod 12 with your hand and press it downward. The change in the angle of the pull rod 12 forces the connecting rod 14 to squeeze the push rod 13 downward, and drives the sliding block 10 to slide downward to squeeze the spring 9. Since the length of the insertion strip 20 is adjusted according to the length of the capacitor, when the insertion strip 20 is inserted to the bottom of the slot 2, the upper end of the capacitor is just inserted into the fixing groove 22 on the surface of the fixing plate 15, which fixes the capacitor while preventing damage to the capacitor. At this time, push the limit block 3 to the right so that the limit block 3 is inserted into the limit slot 19 to prevent the fixing plate 15 from rebounding due to the force of the spring 9. After completion, the capacitance can be detected.
