Description

Technical Field

[0001] The utility model relates to the technical field of AC-DC control voltage regulators, and specifically relates to an AC-DC control voltage regulator with good anti-interference effect. Background Technique

[0002] AC-DC voltage regulators are power conversion devices widely used in electronic equipment and industrial applications, mainly used to convert alternating current (AC) into stable direct current (DC). While ensuring the stability and quality of the output voltage, these voltage regulators provide reliable power supply for various devices.

[0003] At present, the overall structure of the existing AC-DC control voltage regulator is relatively simple. Once damaged, it is very difficult to disassemble, and it cannot be well fixed after installation, which leads to the AC-DC control voltage regulator falling off and misaligning due to vibration after installation, affecting the later use.

[0004] Therefore, in view of this, in view of the existing structural deficiencies, research and improvement are carried out, and an AC-DC control voltage regulator with good anti-interference effect is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an AC-DC control voltage regulator with good anti-interference effect to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an AC-DC control voltage regulator with good anti-interference effect, including a base and a stabilizing component. There are positioning guards around the top of the base, and a voltage regulator main body is arranged inside the base. The stabilizing component for preventing the voltage regulator main body from shaking after installation is installed inside the voltage regulator main body. The stabilizing component includes a positioning frame, a sleeve, a movable rod and a spring. Sleeves are fixedly installed at the four corners of the top of the positioning frame, and movable rods are slidably connected to the inner walls of the sleeves. Springs are sleeved on the outer walls of the movable rods.

[0007] Preferably, an upper conductive pin is electrically connected to the top of the voltage regulator main body, and a rectifier is electrically connected to the end of the upper conductive pin away from the voltage regulator main body.

[0008] Preferably, metal contacts are arranged on both sides of the bottom of the voltage regulator main body, and a metal seat is connected to the bottom of the metal contacts.

[0009] Preferably, the end of the metal seat is electrically connected to a lower conductive pin, and the overall shape of the lower conductive pin is set in a "Z" shape.

[0010] Preferably, movable buckles are symmetrically arranged on the front and rear sides of the base, and the overall shape of the movable buckles is set in a "C" shape.

[0011] Preferably, a cover plate is sleeved on the outer wall of the positioning edge protector, and the cover plate is fixedly clamped with the base through a movable buckle.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The AC-DC control voltage regulator with good anti-interference effect can not only prevent disconnection due to long-term vibration after installation through extrusion positioning, but also improve the overall anti-electromagnetic interference ability of the voltage regulator body.

[0013] 1. Through the setting of the stabilizing component of the present utility model, the springs arranged at the four corners of the top of the positioning frame push the movable rod to be pulled out from the inside of the sleeve, and the sleeve moves downward to push the positioning frame downward, tightly pressing the voltage regulator body into the base. The metal contacts arranged inside the base are energized with the lower conductive pins arranged at the end of the metal seat. This enables the voltage regulator body to be connected to the metal seat again under the action of the spring when it is vibrated, so as to achieve the purpose of preventing disconnection due to long-term vibration through extrusion positioning after installation;

[0014] 2. Through the setting of the rectifier of the present utility model, the rectifier can effectively improve the efficiency and low-noise design, and at the same time can reduce electromagnetic interference and improve the anti-interference ability of the power supply module, ensuring the stability of the DC output voltage.
