Description

Technical Field

[0001] This utility model relates to the technical field of microcapacitance detection, and more specifically, to a wiring device for microcapacitance detection. Background Technology

[0002] A microcapacitor typically refers to a capacitor used to fine-tune the capacitance value in a circuit; it is also called a trimmer capacitor. A trimmer capacitor consists of two parallel-plate-like electrodes sandwiched in an insulating material. By rotating the external structure of the trimmer capacitor, the distance between the two electrode plates can be changed, thus affecting the capacitance. During the testing process, a microcapacitor is tested by connecting the capacitor's leads to a testing device using connecting wires.

[0003] However, the existing wiring method for connecting the pins of microcapacitors mainly involves directly wrapping the connecting wires on the testing equipment around the pins of the microcapacitor. Since the pins of microcapacitors are small, this wiring method is not only inconvenient to operate, but also affects the wiring efficiency. Therefore, we propose a wiring device for microcapacitor testing to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a wire-connecting device for microcapacitor testing. It utilizes the elastic force of a spring to reset the outer bushing, while simultaneously using a guide post head and a limiting hole to limit the outer bushing. The inner edge of the bottom opening of the outer bushing abuts against the inclined boss, causing the claws to retract towards the inside of the wire-connecting sleeve, thereby abutting the flange against the pin. The connecting wire connects to the equipment used for microcapacitor body testing. The structure is simple, the operation is convenient, and the efficiency of pin wire connection on the microcapacitor body is improved.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A microcapacitor detection wiring device includes a microcapacitor body and pins connected to the positive and negative terminals of the microcapacitor body. A wiring sleeve is detachably connected to the pin. The bottom end of the wiring sleeve has a notch, and the inner side of the notch is provided with a claw integrally formed with the wiring sleeve. The outer edge of the bottom end of the claw is integrally formed with a beveled boss, and the inner edge of the bottom end of the claw is integrally formed with a flange that abuts against the outer wall of the pin. Limiting holes are symmetrically formed above the claw at the axial position of the wiring sleeve.

[0009] The outer side of the connecting sleeve is movably connected to an outer bushing, and the inner edge of the bottom end of the outer bushing abuts against the inclined boss. The inner wall of the outer bushing is symmetrically equipped with guide pins that are slidably connected to the limiting hole.

[0010] A spring is provided above the outer bushing and sleeved on the outside of the wire-connecting sleeve;

[0011] A connecting wire is installed at the top of the wiring sleeve.

[0012] Furthermore, a wrench is fixedly connected to the top of the outer bushing, and two wrenches are symmetrically arranged at the radial position of the outer bushing.

[0013] Furthermore, the top of the pin abuts against the inner wall of the bonding sleeve.

[0014] Furthermore, three notches are specifically provided at the bottom end of the wiring sleeve, and the angle between the centerlines of two adjacent notches corresponding to the centerline of the wiring sleeve is 120°.

[0015] Furthermore, both the top edge of the connecting sleeve and the outer bushing are integrally formed with a connecting platform.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] (1) In this scheme, the outer bushing is pulled upward relative to the bonding sleeve, while the guide post moves synchronously with the limiting hole, and the spring sleeved on the outside of the outer bushing is compressed and deformed. Then the bonding sleeve is placed on the pin of the microcapacitor body. After the outer bushing is released, the elastic force of the spring is used to reset the outer bushing. At the same time, the guide post is used with the limiting hole to limit the outer bushing. The inner edge of the bottom opening of the outer bushing abuts against the inclined boss, and the claws retract towards the inside of the bonding sleeve, so that the flange abuts against the pin. The connecting wire is connected to the equipment used for testing the microcapacitor body. The structure is simple, the operation is convenient, and the efficiency of bonding the pins on the microcapacitor body is improved.

[0029] Example:

[0030] Please see Figure 1-4 A microcapacitor detection wiring device includes a microcapacitor body 1 and pins 2 connected to the positive and negative ends of the microcapacitor body 1. A wiring sleeve 3 is detachably connected to the pins 2. The bottom end of the wiring sleeve 3 has a notch, and the inner side of the notch is provided with a claw 4 integrally formed with the wiring sleeve 3. The outer edge of the bottom end of the claw 4 is integrally formed with a beveled boss 5, and the inner edge of the bottom end of the claw 4 is integrally formed with a flange 6 that abuts against the outer wall of the pin 2. Limiting holes 7 are symmetrically opened above the claw 4 at the axial position of the wiring sleeve 3.

[0031] The outer side of the connecting sleeve 3 is movably connected to the outer bushing 8, and the inner edge of the bottom end of the outer bushing 8 abuts against the inclined boss 5. The inner wall of the outer bushing 8 is symmetrically equipped with guide pins 9 that are slidably connected to the limiting hole 7.

[0032] A spring 11 is provided above the outer bushing 8 and is sleeved on the outside of the wire-connecting sleeve 3;

[0033] A connecting wire 12 is installed at the top of the connecting sleeve 3;

[0034] It should be noted that when using this microcapacitor detection wiring device, the outer bushing 8 is first pulled upward relative to the wiring sleeve 3, while the guide post 9 moves synchronously with the limiting hole 7, compressing and deforming the spring 11 fitted on the outside of the outer bushing 8. Then, the wiring sleeve 3 is fitted onto the pin 2 of the microcapacitor body 1. After releasing the outer bushing 8, the elastic force of the spring 11 is used to reset the outer bushing 8. At the same time, the guide post 9 is used to limit the outer bushing 8 with the limiting hole 7, and the inner edge of the bottom opening of the outer bushing 8 abuts against the inclined boss 5, causing the claw 4 to retract towards the inside of the wiring sleeve 3, so that the flange 6 abuts against the pin 2. The connecting wire 12 connects to the equipment used for detecting the microcapacitor body 1. The structure is simple, the operation is convenient, and the wiring efficiency of the pin 2 on the microcapacitor body 1 is improved.

[0035] like Figure 2 , Figure 4 As shown, a wrench 10 is fixedly connected to the top of the outer bushing 8, and two wrenches 10 are symmetrically arranged in the radial position of the outer bushing 8.

[0036] It should be noted that by setting a wrench 10 at the top of the outer bushing 8, it is convenient to use the wrench 10 to drag the outer bushing 8 relative to the wire sleeve 3.

[0037] like Figure 1 , Figure 2 As shown, the top of pin 2 abuts against the inner wall of the bonding sleeve 3;

[0038] It should be noted that by having the top of pin 2 abut against the inner wall of the bonding sleeve 3, the bonding sleeve 3 is fitted onto the outside of pin 2, which facilitates quick bonding through pin 2.

[0039] like Figure 3 As shown, there are three notches specifically provided at the bottom end of the wire-laying sleeve 3, and the angle between the center lines of two adjacent notches corresponding to the center line of the wire-laying sleeve 3 is 120°.

[0040] It should be noted that the pin 2 is clamped by the claws 4 with multiple notches at the bottom end of the wire sleeve 3, which ensures the stability of the clamping of the pin 2.

[0041] like Figure 2 As shown, the top edge of both the wire sleeve 3 and the outer bushing 8 is integrally formed with a connecting platform, and the two ends of the spring 11 are respectively connected to the connecting platforms provided on the wire sleeve 3 and the outer bushing 8.

[0042] It should be noted that, firstly, the outer bushing 8 is pulled upward relative to the wire sleeve 3, while the guide post 9 moves synchronously with the limiting hole 7, and the spring 11 sleeved on the outside of the outer bushing 8 is compressed and deformed. Then, the wire sleeve 3 is sleeved on the pin 2 set on the microcapacitor body 1. After the outer bushing 8 is released, the elastic force of the spring 11 is used to reset the outer bushing 8, which is conducive to the quick clamping and fixing of the pin 2.

[0043] The connecting sleeve 3 is made of copper-aluminum alloy, and the outer bushing 8 is made of ABS resin.

[0044] In use: First, pull the outer bushing 8 upward relative to the wire sleeve 3, while the guide post 9 moves synchronously with the limiting hole 7, and compresses and deforms the spring 11 fitted on the outside of the outer bushing 8. Then, fit the wire sleeve 3 onto the pin 2 of the microcapacitor body 1. After releasing the outer bushing 8, use the elastic force of the spring 11 to reset the outer bushing 8. At the same time, use the guide post 9 with the limiting hole 7 to limit the outer bushing 8, and abut against the inclined boss 5 through the inner edge of the bottom opening of the outer bushing 8. Retract the claw 4 towards the inside of the wire sleeve 3, so that the flange 6 abuts against the pin 2. The connecting wire 12 is connected to the device for detecting the microcapacitor body 1.

[0045] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto.
