Description

An embedded magnetic element with a protective device

technical field

The utility model relates to an embedded magnetic element, in particular to an embedded magnetic element which can make electronic equipment thinner.

Background technique

New high-efficiency and energy-saving lighting appliances, especially LED lighting appliances, are currently entering various lighting markets with a rapid development momentum. In order to meet the needs of people in various applications, light and thin lighting appliances are an inevitable trend in the development of the lighting market. According to the feedback we got from major lighting manufacturers around the world, the height of lighting appliances has been reduced from 36mm to 30mm and then to 20mm, 16mm or even 14mm. It can be seen that the thinning and thinning of lighting appliances makes the low profile of circuit components inevitable.

The thinning and thinning of lighting fixtures puts forward low requirements for the height of magnetic components in lighting appliances. Under the requirement of power transmission, the height of existing traditional magnetic components has encountered bottlenecks in the design and manufacturing process. In order to maintain sufficient transmission power while achieving low profile, existing magnetic components usually use enlarged plane area to achieve compressed product height, resulting in difficult product production and low reliability, and the excessively large plane area makes magnetic components When installed on a printed circuit board, it occupies a large area, resulting in an increase in cost. Even some products cannot be thinned due to volume limitations.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an embeddable magnetic element which is convenient for production, safe and reliable, reasonable in cost and can make electronic equipment thinner.

The technical solution adopted by the utility model is: the utility model includes a magnetic element, and the magnetic element includes a magnetic core, a skeleton, a coil wound on the skeleton, and a coil set on the skeleton and electrically connected to the coil. For several pins, the lower part of the magnetic element protrudes downward. When installing, a mounting hole matching the lower part is provided on the mounting plate first, and then the lower part is embedded in the mounting hole.

The magnetic element is cut in a "convex" shape along the direction in which the pins are led out.

The embedded magnetic element with a protective device also includes a protective device, the lower end of the protective device is provided with a protrusion matching the mounting hole, and the upper part of the protective device is provided with a The outer side of the protective device is provided with an anti-sinking convex edge.

The ends of the pins are bent outwards.

The beneficial effects of the utility model are: because the utility model adopts an embedded design, it includes a magnetic element, and the magnetic element includes a magnetic core, a skeleton, a coil wound on the skeleton and is arranged on the skeleton and is connected to the A number of pins electrically connected to the coil, the lower part of the magnetic element protrudes downwards, when installing, first set a mounting hole on the mounting plate that matches the lower part, and then insert the lower part into the mounting hole , thus, the utility model has the following advantages when installed and used:

1. The utility model can reduce the height of the element by 15%-50% due to the difference in power without increasing the area occupied by the magnetic element on the PCB board, which can well meet the requirements of light and thin lighting appliances Require;

2. The embedded magnetic element of the utility model is easy to design, convenient to produce, safe and reliable, and reasonable in cost. And the embedded magnetic element is installed on the printed circuit board to facilitate wave soldering or reflow soldering, and can also realize automatic patch installation, so the utility model also has great advantages in the installation cost of the element;

3. Compared with the existing low-profile design, the embedded magnetic element of the present invention has the advantage of occupying a small area of the printed circuit board when it is installed on the printed circuit board, so that the printed circuit board can be saved. board cost;

4. The magnetic element is the core element of the lighting appliance. The design of the embedded magnetic element makes it easy to achieve light and thin lighting appliances, thereby accelerating the entry of light and thin lighting appliances into the market, and accelerating the entry of new energy-saving lighting appliances, especially LED lighting, into thousands of households. 10,000 households, promote the accelerated development of new energy-saving lighting-related industrial chains, and contribute to energy conservation and environmental protection.
