UV5R Speaker Mic Cable Support Bracket

thingiverse

The BAOFENG (and clones) budget radio benefits from some matching budget speaker-mics available from online auction sites. Unfortunately although the jacks fit well, it only needs a small lateral force on the jack to create a poor connection. This results in poor, intermittent or no operation of the device. After messing about with several fixes including using rubber bands and glue to support the jack in the correct place I finally designed a proper bracket to support the speaker-mic cable. It holds the cable in such a way as to prevent lateral forces from disconnecting it thus maintaining a good connection. Instructions I used FREECAD to generate the 3D design file. I used an ULTIMAKER to build the part. Settings are 220C, 15%infill, 75mm/second speed. The design is in metric mm. You should be able to print it straight off at 1:1 scale. Print out the part. Unscrew the two screws for the belt clip You will need two M2.5 x 10mm set screws as the originals won't be long enough. Fit the speaker mic to the printed part as per the photographs Plug it into the radio body. Carefully re-assemble the belt-clip, bracket and set screws. You may find the holes for the set screw are a bit tight, this is deliberate so it all holds together. However you can easily widen the holes a bit using the point of a soldering iron.
