Abstract

The invention discloses an anti-short circuit 90° curved plug PCB connector, a PCB board and a manufacturing process, including a shell, a contact piece, a base, pins and potting glue, the shell is provided with grooves and through holes, and the through holes have Two, two through holes are respectively set at both ends of the shell, the base is provided with a cavity for connecting the contacts, the cavity is connected with the contacts, the base is set inside the shell, and the base and the shell are connected with potting glue , the pins are connected to the potting compound, the pins are connected to the contact piece by wires, the pins are perpendicular to the contact piece, and the locking screw passes through the through hole to connect the insert nut. The present invention opens a groove on the shell, and then pours potting glue into the groove, which increases the insulation gap between the first row of pins and the shell after welding, and avoids the easy It causes a short circuit between the first row of pins and the shell or a breakdown due to a too small insulation gap during the withstand voltage 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 ...
