The utility model relates to a bus plate in the distribution automation field, especially to a double layer multifunctional bus plate which can be used in a modem and can enlarge a capacity and minimize communication interference. The double layer multifunctional bus plate mainly comprises printed circuit boards, European style sockets, power supply pins, communication pins, a communication slot and communication ports. The double layer multifunctional bus plate is composed of front and rear layers of printed circuit boards; front and rear circuit boards are mutually parallel and fixed through the communication pins and the communication sockets, wherein the front layer is a printed circuit board welded with the European style socket, the communication pins and the power supply pins and the rear layer is a printed circuit board welded with a communication slot and the communication ports. The double layer multifunctional bus plate solves the technical problems of small bus plate capacity, large size, low accuracy and poor convenience of a present bus plate, increases a capacity of a whole unit, raises application flexibility, effectively minimizes electromagnetic interference between each other and raises data transmission accuracy.
Description
Technical field
The utility model relates to the bus bar plate in power distribution automation field, especially a kind ofly uses in modulator-demodulator, can increase the dilatation amount, reduce the double-layer multifunctional bus bar plate of Communication Jamming.
Background technology
Along with developing rapidly of power distribution automation, interface capacity for modulator-demodulator, volume, accuracy and convenience require more and more higher, in the existing products in markets, general modulator-demodulator adopts the single busbar connection plate structure, port slot and PORT COM integrate, the limited amount of PORT COM, so not only to the capacity of bus bar plate, volume has a great impact, and because the port slot follows PORT COM to be integrated on the bus bar plate, can cause certain electromagnetic interference each other, affect the accuracy of data; The number of fixing bus bar plate slot also can be brought inconvenience to the upgrading of the product in later stage; Limited PORT COM has also directly had influence on itself and being connected of peripheral serial server.
Summary of the invention
Little for solving existing bus bar plate capacity, volume is large, accuracy is low, the technical problem that convenience is poor, the utility model provides a kind of double-layer multifunctional bus bar plate, increase the capacity of whole unit and the flexibility of application, effectively reduced electromagnetic interference each other, improved the accuracy of transfer of data.
The technical scheme that its technical problem that solves the utility model adopts is: the double-layer multifunctional bus bar plate, mainly comprise printed circuit board (PCB), Europlug, power pin, the communication contact pin, communication slot and PORT COM, the double-layer multifunctional bus bar plate is comprised of front and back two layer printed circuit boards, before, rear printed circuit board (PCB) is parallel to each other fixing by the communication contact pin with the slot of communicating by letter, anterior layer is that welding equipment has Europlug, the printed circuit board (PCB) of communication contact pin and power pin, 21 Europlugs from left to right successively welding equipment on front layer printed circuit board front, the power pin welding equipment is in the left side at the front layer printed circuit board back side, be connected with outside terminal by winding displacement, communication contact pin welding equipment is in the up and down both sides at the front layer printed circuit board back side; Rear layer has the printed circuit board (PCB) of communication slot and PORT COM for welding equipment, communication slot welding equipment is in the up and down both sides of rear layer printed circuit board front, three layers of RJ45 communication port from top to bottom successively welding equipment at the rear layer printed circuit board back side, the left side opening rectangle slotted hole of rear layer printed circuit board makes things convenient for outside terminal to pass through the power supply winding displacement and is connected with the power pin of front layer printed circuit board; Forward and backward two-tier circuit plate top margin frame and boundary frame area all have spacing hole, and hold-down screw is fixed on double-deck bus bar plate in the cabinet by spacing hole.
The beneficial effects of the utility model: the design of double-deck bus bar plate, by the contact pin connecting circuit board, Europlug is arranged on the different circuit boards with communication port, effectively reduce electromagnetic interference each other, thereby improved the accuracy of transfer of data; The rear layer circuit board back side of double-layer multifunctional bus bar plate is used for special welding equipment communication port, reserves sufficient position to communication port, can carry out dilatation to communication port as required; The double-layer multifunctional bus bar plate because double-decker design before and after having taked connects by contact pin between the bus bar plate, has improved the capacity of whole unit, if the upgrading of product occurs, only needs to change circuit board and gets final product, and has improved its capacity and flexibility; Europlug and the communication port of double-deck bus bar plate are separated welding equipment, reduced the volume of veneer, have effectively solved the problem that complete machine is distributed to the modulator-demod insufficient space.
