Abstract
This utility model discloses a protection structure for a PCB board of an AC-DC electromagnet, which comprises a PBC board on which electronic elements are welded and a protection housing the shape of which matches with the shapes of electronic elements welded on the PCB board. The protection housing accommodates the PCB board and covers one surface and all side surfaces of the PCB board. The length of the side surface of the protection housing are longer than that of the side surfaces of the PCB board, so that the side surfaces of the protection housing projects from the PCB side surfaces. The other surface of the PCB board is poured with low temperature adhesive to form a low temperature adhesive layer. The low temperature adhesive layer integrates with the protection housing to contain the PCB board and the electronic elements thereon. The protection structure for the PCB board of the AC-DC electromagnet has advantages that the electronic elements are safer and are not messed or flew away in the process of injection modeling, that the reliability and the performance of the product are improved and that the cost is indirectly saved and the profit margin is improved.
Description
Technical field
The utility model relates to a kind of pcb board protection structure of alterating and direct current magnet.
Background technology
At present, the electronic component that alternating current-direct current transforms electromagnet adopts the form of soldering to be welded on the pcb board, causes the direct exposure of electronic component on pcb board, and tinol will melt about 180 degree simultaneously.And the temperature on the pcb board can reach about 250 degree in follow-up injection moulding process, therefore is easy to make the weld of electronic component and pcb board to melt when injection moulding, causes electronic component to be dashed, thereby influences the stability of product.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of pcb board protection structure of alterating and direct current magnet, can effectively protect pcb board and on the safety of electronic component, avoid electronic component to be dashed, thereby guarantee product quality stability.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of pcb board protection structure of alterating and direct current magnet; comprise pcb board; be welded with electronic component on this pcb board; other be provided with a shape and described pcb board and on the containment vessel of electronic component profile coupling; this containment vessel is ccontaining in it and cover surface and all sides of described pcb board with described pcb board; and each side that the side of each side of the corresponding described pcb board of this containment vessel stretches out described pcb board; in addition inject one deck low temperature glue in the another side of described pcb board and form a low temperature glue-line, this low temperature glue-line and described containment vessel be connected to form one structure with described pcb board and on electronic component coat in it.
As further improvement of the utility model, connect by soldering between described electronic component and the pcb board.
As further improvement of the utility model, described electronic component is at least one of diode and PIN pin.
The beneficial effects of the utility model are: 1. electronics is safer zero point, does not have by towards unrest or dash phenomenon.2. strengthen reliability of products, promoted the performance of product.3. indirect saving cost, promoted profit margin.
Description of drawings
Fig. 1 is low temperature glue-line described in the utility model and described containment vessel decomposition texture schematic diagram.
By reference to the accompanying drawings, make the following instructions:
1---pcb board 2---electronic component
3---containment vessel 4---low temperature glue-line
Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection range of the present utility model is not limited to following embodiment, and namely the simple equivalent of being done with the utility model claim and description in every case changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1; a kind of pcb board protection structure of alterating and direct current magnet; comprise pcb board 1; be welded with electronic component 2 on this pcb board; other be provided with a shape and described pcb board and on the containment vessel 3 of electronic component profile coupling; this containment vessel is ccontaining in it and cover surface and all sides of described pcb board with described pcb board; and each side that the side of each side of the corresponding described pcb board of this containment vessel stretches out described pcb board; in addition inject one deck low temperature glue in the another side of described pcb board and form a low temperature glue-line 4, this low temperature glue-line and described containment vessel be connected to form one structure with described pcb board and on electronic component coat in it.Like this, in follow-up process of injection molding because pcb board and on electronic component coated in it fully, even forming temperature is high again, can not influence being connected of electronic component and pcb board yet, thereby guarantee the stability of product quality.
Preferably, connect by soldering between described electronic component and the pcb board.
Preferably, described electronic component is at least one of diode and PIN pin.
