JUNCTION BOX

摘要

The assembly comprises a number of peripherally located ports (3) of the same diameter and releasably connected fittings (12)of variable inlet diameters, and connections. The fittings have castellations (18) and an abutment face (21) defining an annular recess (20). The castellations fit into cutouts (22) in the port so when the fitting is rotated the castellations have tightening nipples which force against the castellations (33) of the port (3) forming a seal between the sealing faces of the port (3) and abutment face (21) of the fitting (12) to prevent lateral movement. The projection (25) in the port rides up over the ramp surface (19) to lock into the recess (27) to prevent rotational movement. The ramp surface is suitably shaped to allow for manual rotation and withdrawal of the connector.
