Anti-short-circuit 90-degree bent-plugged PCB (Printed Circuit Board) connector, PCB and manufacturing process

Abstract

The invention discloses an anti-short-circuit 90-degree bent-plugged PCB (Printed Circuit Board) connector, a PCB and a manufacturing process. The anti-short-circuit 90-degree bent-plugged PCB connector comprises a shell, a contact piece, a base, pins and a potting adhesive, wherein the shell is provided with a groove and two through holes; the two through holes are respectively disposed at two ends of theshell; the base is provided with a cavity for connecting the contact piece; the cavity is connected with the contact piece; the base is disposed inside the shell; the base and the shell are connected with the potting adhesive; the pins are connected to the potting adhesive; the pins and the contact piece are connected by wires; the pins is perpendicular to the contact piece; and locking screws are connected to insert nuts by passing through the through holes. According to the anti-short-circuit 90-degree bent-plugged PCB connector, an insulation gap, formed by welding, between the first row of pins and the shell is enlarged by forming the groove in the shell and then filling the groove with the potting adhesive, thereby avoiding the problem of a short circuit easily caused betweenthe first row of pins and the shell under the tin climbing action after the welding or the problem of breakdown caused by an extremely small insulation gap in a voltage withstanding test.

Description

technical field [0001] The invention relates to the technical field of bent-insert PCB connectors, in particular to a short-circuit-proof 90° bent-inserted PCB connector, a PCB board and a manufacturing process. Background technique [0002] Whether the existing curved plug-in PCB connector is the overall potting type or the tail cover potting type, the flanges of the shell are all made of metal materials, and the connector pins need to be soldered to the assembly. printed circuit board connections for reliable connectivity. [0003] In the process of soldering, there is inevitably the phenomenon of tin climbing. The size of the actual solder joint will be larger than the size of the pin itself after the tin climbing of the soldering place, resulting in the insulation between the first row of pins and the shell after soldering. The gap is reduced, because the insulation gap between the first row of pins and the shell of the connector itself is very small (about 0.6mm), and ...
