Abstract

The utility model discloses a mounting structure of a transformer used for LED TV and Monitor on the PCB board, which comprises the transformer, a housing and the PCB board. The housing is internally provided with a chamber for installing the transformer. The PCB board is provided with a cavity suitable for the size of the outer contour of the housing. The transformer is provided in the chamber of the housing. The housing is provided in the cavity on the PCB board. The mounting structure of a transformer has the following advantages: simple mounting structure, convenient mounting, convenient detachment, facilitated realization to small weight and small size of LED TV and Monitor.

Description

Be used in the mounting structure of a kind of transformer on pcb board of LED TV, Monitor

Technical field

The utility model relates to the mounting structure of transformer, particularly is used in the mounting structure of a kind of transformer on pcb board of LED TV, Monitor.

Background technology

Along with development of electronic technology, LED TV, Monitor are used widely, and just develop towards lighter, thinner, littler direction.Usually, LED TV, transformer among the Monitor comprises the line bag and the online magnetic core of wrapping is set, its center line bag is by skeleton, line bag and adhesive plaster are formed, the skeleton both sides are provided with stitch, transformer is to realize on perforation by stitch being welded on pcb board or the soldering sheet in the installation on the pcb board, the mounting structure that this stitch is welded on the pcb board causes product to have higher height, thereby make LED TV, Monitor can't really realize compactization, in addition, this structure can cause the installation and removal of transformer cumbersome, can't guarantee that also transformer coiling wraps in the height on the pcb board.

The utility model content

For addressing the above problem, the utility model provides a kind of LED of helping TV, Monitor to realize the mounting structure of a kind of transformer on pcb board that is used in LED TV, Monitor of compactization, simple in structure, convenient disassembly.

The utility model is that the technical scheme that its problem of solution is adopted is:

Be used in the mounting structure of a kind of transformer on pcb board of LED TV, Monitor, comprise transformer, housing and pcb board, be provided with the cavity volume that is used to install transformer in the housing, pcb board is provided with the cavity that adapts with described housing gabarit size, transformer is installed in the cavity volume of housing, and housing is installed in the cavity on the pcb board.

As the further improvement of such scheme, housing is provided with and is used for determining that the line of transformer wraps in the positioner of setting height(from bottom) on the pcb board.

Further, described positioner is to be arranged on the housing locating blades both sides at least, that launch to side.

Further, be provided with cavity between the madial wall of cavity volume and the positioner, the limit leg of the magnetic core both sides of transformer places in the cavity of housing.

The beneficial effects of the utility model are: the utility model is installed in the housing by line bag and the magnetic core with transformer, and whole housing is communicated with transformer is installed in together in the cavity of pcb board, make the height of transformer on the pcb board face be protected, help dwindling taking up room of transformer and peripheral product (as electric capacity, diode etc.) thereof, thereby make electrical equipment such as LED TV, Monitor become lighter, thinner, littler, simple in structure, its installation and removal are also very convenient.In addition, positioner can determine that the transformer line wraps in the interior setting height(from bottom) in cavity on the pcb board; The setting of locating blades not only can easily be determined height or the degree of depth of transformer on pcb board, the steadiness in the time of can also increasing transformer and be installed on the pcb board; The limit leg of magnetic core has also obtained sufficient protection.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is that transformer of the present utility model is installed in the schematic diagram on the pcb board;

Fig. 2 is the stereogram of housing of the present utility model;

Fig. 3 is the side schematic view of housing of the present utility model.

Embodiment

Referring to figs. 1 through Fig. 3, the mounting structure of a kind of transformer on pcb board that is used in LED TV, Monitor of the present utility model, comprise transformer, housing 1 and pcb board 3, be provided with the cavity volume 2 that is used to install transformer in the housing 1, pcb board 3 is provided with the cavity that adapts with described housing 1 gabarit size, transformer is installed in the cavity volume 2 of housing 1, and housing 1 is installed in the cavity on the pcb board 3.Wherein, transformer comprises line bag 21 and magnetic core 22, and the two ends of transformer framework also are provided with stitch 23 in the line bag 21, and the end of stitch 23 stretches out outside the housing 1 and inserts in the pcb board 3.Transformer integral body is placed in the housing 1, by on pcb board 3, digging out the cavity that a size and described housing 1 adapt, just housing 1 can be installed on the pcb board 3 together with transformer, this structure has not only made things convenient for installation and removal, and can make full use of pcb board 3 inner spaces, reduce the volume of transformer and even its end product, make electrical equipment such as LED TV, Monitor to develop towards lighter, thinner, littler direction.

In order to determine setting height(from bottom) in the cavity of transformer line bag 21 on pcb board 3, can on housing 1, positioner be set.

As preferred mode, described positioner be arranged at both sides on the housing 1, be the locating blades 4 that wing or column are launched to side.In the process of processing, can be in the both sides of housing 1 two locating blades 4 of each machine-shaping, and pre-determine locating blades 4 on housing 1 the position and the height, just need not to measure again when on pcb board 3, transformer being installed like this, can guarantee pack into the degree of depth in the pcb board 3 of transformer, it is more accurate to locate.In case transformer is packed in the pcb board 3 after, locating blades 4 can prevent effectively that just housing 1 from skew up and down taking place.In addition, when pcb board 3 up-down vibration, the performance that locating blades 4 gets loose stitch 23 opposings increases considerably.

Further; be provided with cavity 5 between the madial wall of cavity volume 2 and the positioner; the limit leg of magnetic core 22 both sides of transformer places in the cavity 5 of housing 1; can each limit leg of magnetic core 22 be played a protective role; make it avoid extraneous collision and impaired, also can guarantee the electrical characteristic safety distance of transformer and peripheral part simultaneously.

In addition, be installed on stability on the pcb board, can between locating blades 4 and pcb board 3, apply fixing glue, more effectively ensure the highly stable of transformer for further increasing transformer.

Above-mentionedly just preferred embodiment of the present utility model is illustrated and describes; but execution mode of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
