Printed circuit board and method for manufacturing printed circuit board
ActiveCN104768326BAffect electrical performanceElectrical connection printed elementsPrinted element electric connection formationMedia layerPrinted circuit board
The invention provides a printed circuit board. The printed circuit board comprises a plurality of sub board bodies. The sub board bodies comprise the first sub board body and the second sub board body. A first medium layer is arranged between the first sub board body and the second sub board body. The first sub board body is located on the outmost side of the printed circuit board. The first surface of the first medium layer is in press fit with the pressing face of the first sub board body, and the second surface is in press fit with the second sub board body. The part, protruding out of the first surface, of a first guide connection column covers hole openings of via holes of the first sub board body. The part, protruding out of the second surface, of the first guide connection column covers hole openings of via holes of the second sub board body so that a conductive metal layer of the via holes of the first sub board body can be electrically connected with a conductive meal layer of the via holes of the second sub board body in a breakover mode through the first guide connection column. The invention provides a printed circuit board manufacturing method.

The invention discloses a plastic-encapsulated branch device which comprises a locking nut. A shuttle-shaped spring chuck is arranged in the locking nut. The spring chuck and the locking nut are locked through a tapered sleeve. The tapered sleeve is connected with a branch cable through a straight terminal. A first filling plastic layer wraps outside the locking nut. The first filling plastic layer is internally provided with a Z-shaped terminal. One end of the Z-shaped terminal is coaxial with the locking nut, and the other end is connected with the branch cable. The first filling plastic layer is wrapped by a second filling plastic layer. One end of the first filling plastic layer and one end of the second filling plastic layer are fixedly connected with a flange plate and a cable gland.The assembling process comprises steps S1-S9. The device is fixed on the customer's mechanism through the flange plate between the client sides so that the construction is convenient and use is convenient for the customer; the forming process completely fills the gaps of the parts, and the electrical performance is better under the same volume; and the clamping process is adopted to realize the power extraction of the shielding layer, and the production process is simple and reliable.
