Description
Technical field
The utility model relates to electronic technology field, particularly structure on a kind of many core transformers plate.
Background technology
DC-DC module power source is widely used in the communications fields such as switching equipment, access device, mobile communication, microwave communication, optical transport, router, and the field such as automotive electronics, Aero-Space.In use, system, according to the operating voltage of circuit, is selected the number of coupling DC-DC module power source, is grouped together by multiple DC-DC module power source, forms the power module that power density is high, conversion efficiency is high, its compact conformation.
User can select multiple core transformers unit in parallel according to actual power demand, produce power superposition, but when core transformers arrangement is on circuit boards subject to spatial limitation, its density is high, and each core transformers operationally will produce heat, easily cause modular power source enclosure interior heat to discharge to be obstructed, in the course of time, significantly reduced in the life-span of core transformers.
utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of connection and reasonable arrangement and structure on compact conformation, long service life and non-interference many core transformers plate.
The purpose of this utility model is achieved through the following technical solutions: structure on a kind of many core transformers plate, it comprises circuit board, multiple core transformers unit and fixed lobe, circuit board offers multiple through hole matched with core transformers unit, core transformers unit is fixed in through hole, the side of core transformers unit is provided with pin, pin is connected with the circuit on circuit board, the both sides of each core transformers unit are provided with the limited impression concaved, fixed lobe is arranged on the case inside of mounting circuit boards, limited impression and fixed lobe closely cooperate, multiple core transformers unit is installed in parallel on circuit boards.
Described fixed lobe comprises base station and separator, and the housing of base station and mounting circuit boards is one-body molded, and separator is bonded on base station, and the another side of separator compresses on circuit boards.
Described separator is heat conductive silica gel.
The utility model has the following advantages:
1, core transformers unit is fixed in through hole on circuit boards, makes circuit board be positioned at the middle part of core transformers unit, compared to side core transformers unit being fixed on circuit board, its thickness is thinner, it is more reasonable to arrange, compact conformation, reduces the installing space of core transformers further.
2, fixed lobe is set in the both sides of core transformers unit, the limited impression of core transformers unit both sides and fixed lobe are closely cooperated, the parts of fixed lobe and circuit board contacts are heat conductive silica gel simultaneously, there is heat conduction, insulation and shockproof triple role simultaneously, there is rapid heat dissipation, not easily short circuit and shake little feature, being conducive to the useful life extending core transformers.
3, multiple core transformers unit is installed on circuit boards by mode in parallel, though one of them core transformers unit short circuit or damage and cannot power output time, do not affect overall output yet, non-interference between each core transformers unit.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection range of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, structure on a kind of many core transformers plate, it comprises circuit board 1, multiple core transformers unit 2 and fixed lobe 3, circuit board 1 offers multiple through hole matched with core transformers unit 2, core transformers unit 2 is fixed in through hole, as shown in Figure 3 and Figure 4, the side of core transformers unit 2 is provided with pin 5, pin 5 is connected with the circuit on circuit board 1, the both sides of each core transformers unit 2 are provided with the limited impression 4 concaved, fixed lobe 3 is arranged on the case inside of mounting circuit boards 1, limited impression 4 and fixed lobe 3 closely cooperate, multiple core transformers unit 2 is installed in parallel on the circuit card 1.
As shown in Figure 5, described fixed lobe 3 comprises base station 6 and separator 7, and base station 6 is one-body molded with the housing of mounting circuit boards 1, and separator 7 is bonded on base station 6, and the another side of separator 7 compresses on the circuit card 1; Described separator 7 is heat conductive silica gel.The height of base station 6 is lower than the height of core transformers unit 2, the height of fixed lobe 3 is higher than the height of core transformers unit 2, when mounting circuit boards 1, withhold in modular power source housing together with core transformers unit 2, be stuck in by core transformers unit 2 inside fixed lobe 3, during compression, separator 7 is squeezed and is compressed, make the height of fixed lobe 3 equal the height of core transformers unit 2, core transformers unit 2 is embedded in fixed lobe 3.And separator 7 is heat conductive silica gel, its heat conductivility is stronger, the heat that core transformers unit 2 produces can be taken away by heat conductive silica gel in time, it is nonmetallic materials simultaneously, there is insulation characterisitic, and heat conductive silica gel is compressed because having elasticity, also has antihunt action, therefore fixed lobe 3 also serves heat conduction, insulation and shockproof triple role while fixed magnetic core transformer unit 2.
