Description

Technical Field

[0001] This utility model relates to the field of capacitor connection technology, and in particular to an aluminum electrolytic capacitor with stable connection. Background Technology

[0002] In existing aluminum electrolytic capacitors, electrical connection terminals are usually made using leads or solder feet. They are fixed to the circuit board by welding. The leads are mostly made of aluminum wire or tinned copper wire, and the surface is pretreated to enhance the welding reliability. The solder feet are directly formed on the capacitor shell to facilitate automated welding operations.

[0003] Currently, existing aluminum electrolytic capacitors typically rely on traditional manual fixing methods in the welding process. Although the welding operation can be completed with difficulty, it cannot provide stable support during welding, which makes them prone to shaking or displacement during the welding process, leading to quality problems such as incomplete welding and missing welding. At the same time, the lack of protection makes the capacitors susceptible to damage from external impacts or environmental factors after welding. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot provide stable support during welding, leading to shaking or displacement during the welding process, and consequently causing incomplete or missing welds. The invention proposes a stable aluminum electrolytic capacitor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stable aluminum electrolytic capacitor includes:

[0007] The capacitor body has positive and negative leads symmetrically arranged at its bottom.

[0008] The capacitor body is provided with a support component, which is used to fix and support the installed capacitor body. The support component is also provided with a fixing component, which is used to fix the position of the capacitor body for easy welding.

[0009] In one possible design, the support assembly includes a cover and a ring frame fitted over the capacitor body. The bottom of the cover is fixedly mounted on the top of the ring frame. The bottom of the ring frame is symmetrically bonded with adhesive, and both surfaces of the adhesive are covered with anti-stick coating. The top of the ring frame has two symmetrically formed slots.

[0010] In one possible design, the fixing assembly includes two detachable locking blocks that are respectively locked inside two slots. The two locking blocks are fixedly mounted on the same fixing frame at their far ends. A lead screw is slidably passed through the top of the fixing frame. A knob is fixedly mounted at the top of the lead screw. A clamping plate is threadedly connected to the outside of the lead screw at the bottom of the fixing frame.

[0011] In one possible design, a limiting block is fixedly provided at the bottom end of the lead screw to prevent the clamping plate from detaching, and a U-shaped groove is provided at the bottom of the fixing frame to facilitate the sliding of the clamping plate.

[0012] In one possible design, the bottom of the ring frame has fastening grooves on both sides away from the adhesive, and the top walls of both fastening grooves have anti-slip stripes.

[0013] In one possible design, a rubber pad is embedded in the bottom of the cover.

[0014] In this application, when starting to use it, first take out the capacitor body that needs to be soldered and prepare soldering tools (solder, soldering iron, etc.). Then insert the positive and negative leads at the bottom of the capacitor body into the holes reserved in the circuit board or electronic components. Then put the cover and ring on the outside of the capacitor body and move it along the outside of the capacitor body towards the circuit board or electronic components at the bottom until they fit together.

[0015] Next, align the two locking blocks at the bottom of the mounting bracket with the locking slots at the top of the ring bracket, and press vertically downwards until the locking blocks are fully engaged. Then, rotate the knob. As the knob rotates, it drives the lead screw to rotate, which in turn drives the clamping plate to rise at a constant speed. During the upward movement of the clamping plate, hold it until it enters the U-shaped groove at the bottom of the mounting bracket. Then, continue to rotate the knob until the top of the clamping plate is close to the bottom of the circuit board or electronic component until it touches it. Continue to rotate the knob until the mounting bracket is stable on the circuit board or electronic component, thereby stably fixing the capacitor body in the position where it needs to be soldered.

[0016] Then flip the circuit board or electronic component over and solder the positive and negative terminals of the capacitor body onto the circuit board or electronic component. After soldering, turn the knob in the opposite direction to drive the lead screw to rotate in the opposite direction. The reverse rotation of the lead screw will cause the clamping plate to move downward on the lead screw, releasing the fixing bracket. Then remove the two clips on the fixing bracket from the slots of the ring bracket to release the two from the engagement. Then, hold the clip slot and remove the cover and ring bracket from the capacitor body. After removing them, peel off the anti-adhesive at the bottom of the ring bracket and put the ring bracket and cover bracket with the anti-adhesive removed back onto the outside of the capacitor body until the ring bracket is against the surface of the circuit board or electronic component. Then, press the cover bracket down to make the adhesive stick to the surface of the circuit board or electronic component.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, the support components are designed to support the aluminum electrolytic capacitor body. They not only work with the fixing components to maintain the stability of the capacitor body during welding, but also provide protection by wrapping it after welding.

[0019] This invention provides a stable clamping force during welding by setting a fixing component, which prevents the capacitor from shaking. This effectively solves the problems of inaccurate positioning and laborious operation in traditional manual fixing methods, and significantly improves welding quality and work efficiency.

[0020] This invention combines a support component and a fixing component, which can provide stable support and precise positioning for the capacitor body during welding, and provide continuous protection for it after welding, thus significantly improving welding quality and work efficiency.
