SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a design a case hardwire cable seal structure, solve on the one hand and gather light chamber cable and walk the problem that the line is sealed to the electric layer, on the other hand improves the maneuverability and the maintainability of the connection of the heavy current cable in spotlight chamber.

The utility model discloses a reach above-mentioned purpose, specifically can realize through following technical scheme:

the utility model provides a quick-witted case hard cable seal structure, includes quick-witted case, sets up the through wires hole that link up on the quick-witted case, and the through wires downthehole portion includes chamfer portion, expands appearance hole, receipts line hole and sealed hole along the axial in proper order, and the dilatation hole diameter is 2-6 times of cable diameter, receives line hole minimum diameter and is less than dilatation hole diameter to for cable diameter 1-1.3 times, sealed hole diameter is greater than receipts line hole minimum diameter, installs the sealing washer in the sealed hole, is fixed with the clamp plate on the quick-witted case outer wall in the sealing washer outside.

Furthermore, the axial length of the expansion hole accounts for 2/3-4/5 of the length of the threading hole.

Furthermore, the pressing plate is of a plate-shaped structure with a U-shaped groove on one side, and the groove width of the U-shaped groove is smaller than the diameter of the sealing ring and larger than the diameter of the cable.

Furthermore, the pressure plate is made of polytetrafluoroethylene material, and the thickness of the pressure plate is 1-3 mm.

Further, the sealing ring is a rubber sealing ring.

Compared with the prior art, the utility model discloses chassis board both sides in the structure use the shoulder hole, and the shoulder hole of one side guarantees the sealed of cable hole for the installation sealing washer design through the clamp plate, and the great darker shoulder hole of one side can let the good performance of penetrating of cable in addition to prevent cable wearing and tearing, can also let harder cable arrangement at last easier.
