[specific embodiment]
Embodiment to lamp cable sealing structure of the present invention is described in further details below in conjunction with accompanying drawing.
As shown in Figure 1, lamp cable sealing structure preferably is applied in a kind of light fixture, can certainly be applied to other electronic equipment, as long as this electronic equipment comprises the external cable line, this lamp cable sealing structure comprises cable 1, sealing sheath 2, locking nut 3, first back-up ring 4, second back-up ring 5, ply-yarn drill 6 and housing 7.Sealing sheath 2 is socketed on the cable 1, and first back-up ring 4 is socketed on the sealing sheath 2, and locking nut 3 is close to first back-up ring 4 and is socketed on the sealing sheath 2, and second back-up ring 5 is close to sealing sheath 2 and is socketed in the end that cable 1 is positioned at housing.Housing 7 is provided with fixed part 8, fixing hole is provided with the screw thread that cooperates with locking nut, locking nut and screw thread screw cable 1, sealing sheath 2 and first back-up ring 4 and second back-up ring 5 are fixed on the housing 7, and fixing hole also is provided with stop portion 9, and second back-up ring 5 is stopped.
As shown in Figure 2, sealing sheath 2 is the round rubber sheath, can certainly be that other loose shape material is made.Sealing sheath 2 comprises cylindrical section 22, conical section 24 and the boss section 26 of one connection successively, less end of conical section 24 external diameters and cylindrical section 22 smooth connections, and the external diameter of an end that is connected with cylindrical section 22 and cylindrical section 22 external diameters equate that the bigger end of conical section 24 external diameters is connected with boss section 26 one.Sealing sheath 2 is provided with a circular hole 28 that runs through cylindrical section 22, conical section 24 and boss section 26, and circular hole 28 diameters equate with the external diameter of cable 1.
As shown in Figure 3, first back-up ring 4 is a metal collar, and first back-up ring 4 is for being circular, and its internal diameter is a bit larger tham sealing sheath 2 cylindrical sections 22 external diameters, and external diameter equates with the external diameter of boss section 26.
As shown in Figure 4, second back-up ring 5 also is a metal collar, and second back-up ring 5 also is circular, and its internal diameter is a bit larger tham the external diameter of cable 1, and its external diameter equates with the external diameter of sealing sheath 2 boss sections 26.
The installation process of lamp cable sealing structure is as follows: at first first back-up ring 4 is enclosed within on the cylindrical section 22 of sealing sheath 2, again cable 1 is passed the circular hole 28 of sealing sheath 2, then second back-up ring 5 being enclosed within cable 1 need place on the end in the housing, be connected to an end of cable 1 socket second back-up ring 5 with ply-yarn drill 6, ply-yarn drill 6 prevents that greater than the external diameter of second back-up ring 5 cable 1 from being extracted from second back-up ring 5; Then first back-up ring 4 is shifted onto boss section 26 roots of sealing sheath 2, made sealing sheath 2 wrap tightly cable 1 outside, form cable seal, at last above-mentioned parts are being inserted in the housing installing hole, and use locking nut 3 lockings.
Because rubber has the incompressible characteristic of volume, in the process of locking locking nut 3, locking nut 3 compresses the gap between the hole wall that first back-up ring 4 makes first back-up ring 4 and second back-up ring 5 crush seal sheaths, the 2 sealed electrical cables 1 and fixing hole.In the present embodiment, the boss section 26 of sealing sheath 2 projectioies is between first back-up ring 4 and second back-up ring 5, second back-up ring 5 is close to the stopper section to the fixing hole internal projection, promote in the process of first back-up ring 4 in locking nut 3 inside rotation locks, because second back-up ring 5 is stopped by the stopper section and can not move, boss section 26 is under the compressing of first back-up ring 4 and second back-up ring 5, and mid portion outwards is out of shape projection and forms sealing with the hole wall of the fixing hole of housing 7.In other embodiments, also boss section 26 can be set,, also can reach similar effect by the size of reasonable adjustment conical section 24 and the internal diameter of first back-up ring 4 and second back-up ring 5.In the process of locking locking nut 3, because the internal diameter of first back-up ring 4 is less than the maximum outside diameter of the conical section 24 of tightening seal sheath, first back-up ring 4 also can will compress between the conical section 24 of sealing sheath 2 and the cable 1.This structural design can form cable and sealing sheath, sealing sheath and the sealing of housing 7 inwalls two places, and whole lamp cable line gateway is sealed up fully, has guaranteed the trouble free service of light fixture.Simultaneously, this simple in structure, size is changeable, and is easy for installation, can be applied to various electronic equipments.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
