Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a low temperature co-fired ceramic planar transformer. Background Art

[0002] Low-temperature co-fired ceramic technology is to make low-temperature sintered ceramic powder into a green ceramic strip with precise thickness and density as a circuit board material. Using ceramic as a circuit board can be used to manufacture planar transformers, which are a type of transformer with the characteristics of high frequency, low shape, small height and high operating frequency.

[0003] After searching, the Chinese patent with publication number CN118899155A: Planar transformer, including a first magnetic core block, a second magnetic core block, a plurality of first PCB windings and a plurality of second PCB windings, the plurality of first PCB windings are made of a first PCB board, the center of the first PCB board is provided with a first rectangular opening, the first PCB board is printed with a copper foil wrapped in a coil shape, and leads to power connection ports with different numbers of turns, the plurality of second PCB windings are made of a second PCB board, the center of the second PCB board is provided with a second rectangular opening, the second PCB board is printed with a copper foil wrapped in a coil shape, and leads to power connection ports with different numbers of turns, realizing multi-tap lead-out of the planar transformer and realizing the function of adjusting the input-output turns ratio, but the above technical solution still has the following deficiencies when implemented:

[0004] (1) Low strength: Planar transformers are made of multiple ceramic circuit boards stacked together. Each stacked circuit board will result in uniform force transmission. Ceramics are brittle materials. Once the substrate is overloaded and cracked, the cracking of one substrate may cause damage to multiple substrates at the same time, affecting the reliability and service life of the transformer.

[0005] (2) Insufficient protection: The substrate of a planar transformer is generally longer than the base. The base covers the part around the core in the middle of the substrate, resulting in part of the structure at both ends of the substrate being exposed to the outside, resulting in insufficient protection for the substrate and the risk of damage.

[0006] (3) Low assembly efficiency: The planar transformer is composed of two upper and lower magnetic cores. When connecting the magnetic cores, the magnetic cores need to be aligned. However, the joint surface of the magnetic cores is relatively smooth and the friction is small. It is easy to deviate during docking, which affects the efficiency of assembly.

[0048] The specific working principle of the present invention is as follows:

[0049] A low-temperature co-fired ceramic planar transformer proposed in the present invention is composed of a base 1, an insulating cover plate 2, a substrate group 5 and a magnetic core. The specific structure and connection method of the planar transformer are prior arts well known to those skilled in the art, and will not be elaborated on here. During installation, the substrate group 5 is first sleeved on the outside of the lower magnetic core 3, and then the insulating cover plate 2 is installed. The positioning rod 808 is aligned with the positioning hole 809, and the insulating cover plate 2 is pushed downward so that the mounting plate is inserted into the mounting groove 807. Then, the eccentric wheel 802 is rotated toward the inner direction of the groove 801, and the eccentric wheel 802 pushes the pin rod 803 to be inserted into the pin hole 805. The mounting block 804 is locked to complete the installation of the insulating cover 2. The structure is simple and can realize the quick disassembly and assembly of the insulating cover 2 and the base 1. When the positioning rod 808 slides downward along the positioning hole 809, the tooth block 903 meshes with the spur gear 902 and drives the spur gear 902 to rotate, and the bidirectional threaded rod 901 rotates accordingly and drives the slide 904 to slide along it. When the slide 904 moves, it will drive the support rod 905 to slide. The support rod 905 pulls the clamping plate 906 to approach the magnetic core and cover the connection between the two magnetic cores, so that the lower magnetic core 3 and the upper magnetic core 4 can be locked, which plays a role in stabilizing the magnetic The effect of the core is then achieved by turning the knob 1 601 to drive the bevel gear 1 602 to rotate, and the push rod 608 is driven to rotate under the transmission of the bevel gear 2 604 and the center rod 603. During the rotation of the push rod 608, it will slide inside the track 609, and then push the support plate 605 to move, and the rubber ring 607 will move accordingly and be clamped on the gap edge of the substrate group 5, so that the substrate group 5 is differentiated, so that there is a movable gap between each substrate group 5, and they are connected by the flexible rubber ring 607, so as to improve the overall flexibility of the substrate group 5, avoid chain damage caused by damage to a single substrate, and improve the reliability of the device. In order to improve the reliability and service life, finally, turn the knob 2 701 to drive the turntable 702 to rotate, and use the arc groove 703 on the turntable 702 to push the vertical rod 705 to move, and the horizontal rod 704 slides inside the slide groove 709, and the protective cover 707 moves to the outside of the insulating cover 2. When the protective cover 707 is completely moved out, the spur gear 1 708 engages with the rack 710. At this time, continuing to move will drive the connecting rod 706 to rotate, and then drive the protective plate to move downward and cover the outer surface of the substrate, thereby protecting the exposed part of the substrate, reducing the risk of substrate damage, and improving the safety of the substrate group 5.
