Novel aluminum shell resistor for communication

The utility model provides a novel aluminum shell resistor for communication, and relates to the technical field of resistors, the inner surface of a side box is uniformly provided with a plurality of preformed grooves which are arranged in parallel, limiting insertion shafts are inserted into the preformed grooves, the inner ends of the limiting insertion shafts penetrate into an outer aluminum shell, pull rods are fixed at the outer ends of the limiting insertion shafts, and the pull rods penetrate out of the side box outwards. A reset spring connected to the outer side of the pull rod in a sleeving mode is fixed between the outer end of the limiting inserting shaft and the inner wall of the reserved groove. A mounting part is movably connected in the outer aluminum shell, limiting grooves are formed in the left side and the right side of the mounting part, a sealing gasket is movably connected to the front end of the mounting part, open grooves are formed in the left side and the right side of the surface
