[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, the first back-up ring 4, the second back-up ring 5, ply-yarn drill 6 and housing 7.Sealing sheath 2 is socketed on the cable 1, and the first back-up ring 4 is socketed on the sealing sheath 2, and locking nut 3 is close to the first back-up ring 4 and is socketed on the sealing sheath 2, and the 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 the first back-up ring 4 and the second back-up ring 5 are fixed on the housing 7, and fixing hole also is provided with stop section 9, and the 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 successively one connection, the 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 larger 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, the first back-up ring 4 is metal collar, and the 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, the second back-up ring 5 also is metal collar, and the 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 the 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 the second back-up ring 5 being enclosed within cable 1 need to place on the end in the housing, be connected to an end of cable 1 socket the second back-up ring 5 with ply-yarn drill 6, ply-yarn drill 6 prevents that greater than the external diameter of the second back-up ring 5 cable 1 from being extracted from the second back-up ring 5; Then the 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 characteristic of volume invariability, in the process of locking locking nut 3, locking nut 3 compresses the gap between the hole wall that the first back-up ring 4 makes the first back-up ring 4 and the second back-up ring 5 crush seal sheaths, 2 sealed electrical cables 1 and fixing hole.In the present embodiment, the boss section 26 of sealing sheath 2 projections is between the first back-up ring 4 and the second back-up ring 5, the second back-up ring 5 is close to the stopper section of fixing hole internal projection, promote in the process of the first back-up ring 4 in locking nut 3 inside rotation locks, because the second back-up ring 5 is stopped by the stopper section and can not move, boss section 26 is under the compression of the first back-up ring 4 and the 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, by the size of reasonable adjustment conical section 24 and the internal diameter of the first back-up ring 4 and the second back-up ring 5, also can reach similar effect.In the process of locking locking nut 3, because the internal diameter of the first back-up ring 4 is less than the maximum outside diameter of the conical section 24 of sealing sheath, the 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 completely sealed, and 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.
