Abstract
The utility model discloses a PCB assembly structure for an alternating and direct current electromagnet. The PCB assembly structure comprises a coil housing used for wrapping an electromagnet coil and a PCB which integrates a circuit used for converting an alternating voltage into a direct voltage. The PCB is provided with electronic parts and a connecting plate. One side face of the connecting plate is fixed on the coil housing. According to the PCB assembly structure for the alternating and direct current electromagnet, the electronic parts, the PCB, the protective housing and other parts are combined ingeniously, and an in-mode molding technology is adopted at last so that a product can be used for a long time in a severe environment, and the performance of the product is improved. In addition, the PCB assembly structure also lowers the overall height of the product, and meets the using requirements of customers. Meanwhile, glue injection time is shortened, the reject ratio is lowered, the cost of the product is reduced, and the reliability of the product has a qualitative leap.
Description
Technical field
The utility model 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, also can use in rugged environment 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 utility model provides a kind of pcb board package assembly of alterating and direct current magnet, the packaging efficiency height, and properties of product are stable.
The utility model 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 for the coil case that coats 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 further improvement of the utility model, described plastic shell is integrally formed by the in-mould injection moulding.
The beneficial effects of the utility model are: 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 structure has also reduced the whole height of product in addition, 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.
