  • panel mount RCA connector (and others) question

    Hi,

    I have a few RCA connector that are panel mounts. I will mount them in a metal chassis and I really don't know where the washers go.

    In picture number two, you can see: 1 is the nut, 2 is a nylon washer, 3 is the ground connector and 4 is another nylon washer... my guess is the ground sits between the washers on the inside of the chassis.

    The same situation occurs with some binding posts... I have mounted tons in MDF but now is a metal chassis and I don't want to short or ground something it is not supposed to.

    Thanks in advance for your help! Cheers

    Nope. The washers are to insulate the connector from the chassis, reducing chances of ground loops. The tabbed washer for the ground connection goes outside the nylon washer between the nut and washer.

      Thanks for your help! So the correct order, from left to right is 1-3-2-4 (chassis metal being between 2 and 4).

        And you understand the hole needs to be as big as the shoulder on nylon washer #4 so it registers in the hole and isolates the connector from the chassis.

        As far as binding posts, these cheap ones also isolate the posts from the chassis with shoulders on the plastic base pieces.

          Bingo. As djg pointed out, make the whole large enough for that little lip in the plastic washer.
