Abstract
The invention discloses a printed circuit board (PCB) assembling structure of an alternating-current-direct-current electromagnet. The PCB assembling structure of the alternating-current-direct-current electromagnet comprises a coil shell used for covering a coil of the electromagnet and a PCB with circuits for converting alternating voltage to direct voltage. Electronic parts and a connecting plate are placed on the PCB. One lateral side of the connecting plate is fixed on the coil shell. Parts such as the electronic parts, the PCB and a protective shell are ingeniously combined together, the PCB can be used in severe environment for a long time by utilizing a forming technology in a mould, and the performance of the PCB is improved. In addition, the structure also reduces the whole height of the PCB, satisfies using requirements of a user, saves glue-pouring time, reduces the rate of defectives and cost of the PCB, and qualitatively improves reliability of the PCB.
Description
Technical field
The present invention relates to a kind of pcb board package assembly of alterating and direct current magnet.
Background technology
At present; the pcb board assembling of alterating and direct current magnet generally is earlier electronics zero device to be welded on the pcb board; utilize screw pcb board to be fixed on the coil case of alternating electromagnet then; at last in order to prevent entering of sealing or other impurity; utilize resin to fill, in rugged environment, also can use with the protection components and parts.But also there is following defective in it: 1. more consuming time, artificial injecting glue is more consuming time, need put glue one time every several hrs.2. because of the problem of sealing, sometimes glue has the phenomenon that leaks outside, and influences outward appearance, promotes defective products.3. product parts is many, the assembling link more, indirect lifting the fraction defective of product.4. the connector whole height promotes, and can not well satisfy requirement of client (customer requirement is the low connector of trying one's best).
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of pcb board package assembly of alterating and direct current magnet, the packaging efficiency height, properties of product are stable.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of pcb board package assembly of alterating and direct current magnet, comprise and be used to coat the coil case of electromagnet coil and be integrated with the pcb board that alternating voltage is converted into dc voltage circuit, described pcb board is provided with electronic component, also be provided with a plate, a side of this connecting plate is fixed on the described coil case; The outer integral coating one deck containment vessel of described pcb board and electronic component thereof, this containment vessel is fixed on the another side of described connecting plate; The outer integral coating one deck plastic shell of described containment vessel and connecting plate thereof.
As a further improvement on the present invention, described plastic shell is integrally formed by the in-mould injection moulding.
The invention has the beneficial effects as follows: combine cleverly by parts such as electronic component, PCB, containment vessels, use in-molded technology at last, product can be used under adverse circumstances for a long time, improved the performance of product.This in addition structure has also reduced the whole height of product, has satisfied client's instructions for use.Saved the injecting glue time simultaneously, reduced fraction defective, reduced the cost of product, and reliability of products has been had a qualitative leap.
