Abstract
Description
Technical Field
[0001] The invention relates to the field of electrical appliance detection, in particular to a detection technology for electrical appliance components, and more specifically to an electrolytic capacitor measurement fixing frame. Background Art
[0002] Capacitors are common electronic components that store electrical energy by storing charge in a medium. Capacitors can be used as filters, couplers, filters, etc., and play an important role in many circuits. Electrolytic capacitors are a type of capacitor, in which electrolytic capacitors have two extended positive and negative lead terminals. In order to facilitate measurement, a capacitance measurement device has emerged, such as Figure 1 As shown in FIG. 1 , the device has a capacitance measurement base, which is mainly composed of a positive electrode connection spring 1, a negative electrode connection spring 2, and a positive electrode connector 4 and a negative electrode connector 5 respectively connected to the positive electrode connection spring and the negative electrode connection spring and fixed on a measurement circuit board 3. Figure 1 It can be seen that there is also a base frame 6, which is generally made of plastic material, so as to ensure the stability of the positions of the positive electrode connecting spring sheet, the negative electrode connecting spring sheet, the positive electrode connector and the negative electrode connector.
[0003] This detection structure can quickly insert the electrolytic capacitor into the shrapnel during detection, and pull out the shrapnel after the detection is completed. Compared with the traditional welding method, it is more convenient and quick, and the circuit board can be reused.
[0004] However, during testing, we found two problems with this structure: first, in some testing scenarios, the entire device is inverted, while in other testing scenarios, the entire device is tilted or even placed vertically. This makes it easy for the positive and negative leads of the capacitor to slip out after being inserted into the corresponding spring clips, and they must be manually fixed, which is not only very inconvenient, but also sometimes due to space limitations, causing operational errors. Second, the connection between the positive and negative lead ends of the capacitor and the spring clips is unstable, which causes deviations in the test results. Summary of the invention
[0005] The problems to be solved by the present invention are exactly the above two problems existing in the current capacitance measuring devices.
[0006] In order to solve these two problems, the present invention discloses a capacitance measurement fixing frame, comprising a vertical support composed of at least two vertical support rods and a horizontal block composed of at least one horizontal rod; the vertical support rod comprises an upper and a lower fixed rod and a spring fixed between the upper and the lower fixed rods; the horizontal block is fixed at the top of the vertical support rib; and it also includes a fastening assembly, the number of the fastening assemblies is the same as the number of the vertical support ribs, and the fastening assemblies are correspondingly fixed at the bottom of the vertical support ribs.
[0007] The present invention forms a capacitance measurement fixing frame with space adjustment capability by means of a spring arranged between an upper and a lower fixing rod, and fixes the capacitance measurement fixing frame and the capacitance measurement device together by means of a fastening assembly. Pulling the spring apart provides sufficient installation space, and the capacitor to be detected is loaded. After the pulling force is removed, the spring retracts, and the horizontal block forms a limit with the capacitor, so that the spring cannot return to a static state, thereby providing pressure to the capacitor to be detected, ensuring that the positive and negative lead ends of the capacitor are tightly inserted into the corresponding spring pieces, and at the same time, even if it is inverted, it will not slide out under the action of the horizontal block.
[0008] Preferably, the horizontal block further comprises an annular rod, the horizontal block is located inside the annular rod, and two ends of the horizontal block are respectively fixed to the inner side of the annular rod.
[0009] Further preferably, two horizontal rods are included, and the two horizontal rods are vertically fixed in the annular rod.
[0010] In a preferred technical solution, the fastening assembly is a screw clamp, for example, a screw clamp with a C-shaped or G-shaped clamp. The clamp is clamped on the edge of the base frame of the capacitance measuring device, and then the screw is continuously tightened, so that the capacitance measuring fixture and the capacitance measuring device are stably fixed together.
[0011] Further preferably, in the structure disclosed in the present invention, plastic components are selected as much as possible. For example, in a preferred solution, the horizontal block is a plastic horizontal block; and / or the upper and lower fixing rods are plastic fixing rods; and / or the screw clamp is a plastic screw clamp.
[0012] The technical solution disclosed in the present invention can effectively solve the problem of unstable connection between the positive and negative lead terminals of the capacitor and the spring in the existing detection, and the problem that the capacitor is easy to slip out in an inverted detection environment, thereby improving the detection stability and the reliability of the detection data. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 Schematic diagram of the capacitance measurement fixture.
[0015] Figure 3 This is a schematic diagram of the structure after the capacitance measurement bracket is installed. DETAILED DESCRIPTION
[0016] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example 1
[0017] like Figure 2The capacitance measuring bracket shown in the figure comprises a vertical support composed of at least two vertical support rods 7 and a horizontal block composed of a first horizontal rod 8 and a second horizontal rod 10; the vertical support rod comprises an upper fixed rod 701, a lower fixed rod 702 and a spring 703 fixed between the upper and lower fixed rods; the horizontal block is fixed to the top of the vertical support ribs; in this embodiment, preferably, it can be seen that the horizontal block also includes an annular rod 9, and it can be seen that the first horizontal rod 8 and the second horizontal rod 10 are perpendicular to each other and fixed in the annular rod 9.
[0018] Combination Figure 2 It can be seen that in this embodiment, we choose a screw clamp with a C-shaped clamp, which is mainly composed of a clamp 11 and a screw 12. The screw 12 is rotated up and down through the screw hole set at the bottom of the clamp 11, so as to achieve fixation with other objects, and further combine Figure 3 It can be seen that after the screw clamp is tightened, it is fixed to the edge of the base frame 6 of the capacitance measuring device.
[0019] When in use, first pull out the spring, insert the lead end of the capacitor to be tested into the spring, and then relax it. The spring will retract under the action of elastic force. When it retracts to the horizontal stop and contacts the capacitor, it cannot continue to retract to a static state due to the limiting effect of the capacitor. At this time, the spring has elastic potential energy, which provides a pressure to tightly fix the capacitor to the capacitance measuring device.
[0020] It is particularly noted that in this embodiment, preferably, the horizontal rod, the fixed rod, and the clamp are all plastic horizontal rods, plastic fixed rods, and plastic clamps, thereby greatly reducing the impact of metal in capacitance measurement.
