Description

Technical Field

[0001] This utility model relates to the field of rivet technology, specifically to an ultra-large inverter rivet. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) energy (from batteries or storage batteries) into alternating current (AC) energy (typically 220V, 50Hz sine wave) with fixed frequency and voltage or adjustable frequency and voltage. It consists of an inverter bridge, control logic, and filter circuits. It is widely used in air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting, etc. When driving to work or traveling, an inverter can be connected to a battery to power appliances and tools. Car inverters with output via the cigarette lighter socket are available in power ratings from 20W, 40W, 80W, 120W to 150W. Higher power inverters require connection to the battery. Connecting household appliances to the output of the power converter allows you to use various electrical appliances in your car. Applicable electrical appliances include: mobile phones, laptops, digital camcorders, cameras, lighting fixtures, electric shavers, CD players, game consoles, PDAs, power tools, car refrigerators, and various travel, camping, and medical emergency appliances. An inverter is a DC-to-AC transformer; it essentially performs a voltage inversion process, similar to a converter. A converter transforms the AC voltage from the power grid into a stable 12V DC output, while an inverter transforms the 12V DC voltage output from the adapter into high-frequency, high-voltage AC power. Both components utilize the widely used pulse-width modulation (PWM) technology.

[0003] The core components are all integrated PWM controllers. The adapter uses the UC3842, while the inverter uses the TL5001 chip. The TL5001 operates within a voltage range of 3.6 to 40V and internally includes an error amplifier, a regulator, an oscillator, a PWM generator with dead-time control, a low-voltage protection circuit, and a short-circuit protection circuit. Rivets are used during inverter assembly. For ultra-large inverters, the rivets are prone to damage due to their simple structure, and rainwater can easily enter the rivets, affecting their lifespan. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-large inverter rivet that solves the problem that, during the riveting process of ultra-large inverter rivets, due to their simple structure, rainwater can enter the rivet and affect its lifespan.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an ultra-large inverter rivet, comprising a rivet body, a cap fixedly connected to the top of the rivet body, a connecting post fixedly connected to the upper surface of the cap, a metal cover fixedly connected to the top of the connecting post, a fastening cylinder provided on the outer surface of the rivet body, and reinforcing protrusions fixedly connected to the outer surface of the rivet body.

[0007] Furthermore, a mating groove is provided at the bottom end of the rivet body, and a mating pin is inserted into the inside of the mating groove.

[0008] Furthermore, a locking cap is fixedly connected to the bottom end of the connecting pin, and the upper surface of the locking cap is fixedly connected to the bottom of the fastening cylinder.

[0009] Furthermore, both the fastening cylinder and the outer surface of the metal cover are provided with an anti-rust coating.

[0010] This utility model provides an ultra-large inverter rivet. It has the following beneficial effects:

[0011] This extra-large inverter rivet, through the cooperation of the cap, connecting post, metal cover, mating groove, mating pin, locking cap, fastening sleeve and reinforcing protrusion, can seal the top of the rivet. At the same time, the locking mechanism at the bottom is more convenient and easier to use. It solves the problem that when riveting extra-large inverter rivets, due to their simple structure, rainwater can enter the inside of the rivet and affect its life. Attached Figure Description
