Abstract
The utility model relates to a cable seal head suitable to fix the box wall of the cable when the cable of the transformer is outgoing. The cable seal head comprises a rotating sheath, a thin hex nut sheathed on the rotating sheath, a base sleeve with the steps and a fastening sheath with a cylinder surface at the outside surface and a conical surface at the inner surface. The fastening sheath is positioned on the step of the base sleeve, and the lower part of the rotating sheath is positioned in the base sleeve and is screwed with the inner wall of the base sleeve. A snap ring sticks at the bottom surface of the rotating sheath, and the inner surface of the snap ring is a cylinder surface. The outside surface of the snap ring is a conical surface matched with the inner surface of the fastening sheath. A sealed liner is positioned in the rotating sheath and the snap ring and abuts to the inner surfaces of the snap ring and the rotating sheath. The utility model has simple structure and favorable effect of sealing, protects the cable and is fixed reliably.
Description
Technical field
The utility model relates to a kind of when being applicable to the transformer cable outlet, the fixing cable seal head of usefulness between the cable box wall.
Background technology
Traditional its structure of cable seal head is to be made of pivoted housing, thin hex nut, lining, adapter sleeve, cover for seat and seal washer as shown in Figure 1.Wherein pivoted housing is fixed on the cable box wall by thin hex nut, the lining holder adapter sleeve and is threaded with pivoted housing, the cover for seat holder seal washer and is connected with bush threads, the pivoted housing bottom is that an outer surface belt tapering, inner surface are the ring on the face of cylinder, and adapter sleeve is that an outer surface is the ring of the face of cylinder, inner surface belt tapering.Turn lining, the lining band the ring that moves extruding pivoted housing bottom on the adapter sleeve and it is out of shape compress cable, reach fixed effect.Turn cover for seat, cover for seat crush seal packing ring is out of shape it and compresses cable, reaches sealing effectiveness.This type of cable seal header structure complexity, the anchor ring that relies on the pivoted housing bottom fully is out of shape and compresses cable, it is excessive to be out of shape required pressure, difficult assurance compresses, and be deformed into permanent deformation, the not reproducible use of seal head, dismounting when being inconvenient to safeguard, local pressure and wedge angle that distortion simultaneously produces destroy cable insulation easily and cause accident.In addition, because mating surface is too much, sealing effectiveness is not good yet.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure at weak point of the prior art, has not only protected cable simultaneously but also can secure fixation and the cable seal head of good sealing effect.
The technical scheme that solution the utility model technical problem is adopted is that this cable seal head comprises pivoted housing, is enclosed within the thin hex nut on pivoted housing top, cover for seat with the level and outer surface to be that the face of cylinder, inner surface are the adapter sleeve of the conical surface, adapter sleeve places on the step of cover for seat, the pivoted housing bottom places in the cover for seat and with the cover for seat inner thread and is connected, there is snap ring to be affixed on the bottom surface of pivoted housing, the snap ring inner surface is the face of cylinder, outer surface is the conical surface that cooperates with the adapter sleeve inner surface, has seal cartridge to place in snap ring and the pivoted housing and with the inner surface of snap ring and pivoted housing and fits.
The utility model has guaranteed the secure fixation of cable, the power of outer bound pair cable is transferred on the cable box, and be not directly delivered to copper busbar, avoid causing the loosening of back panel wiring system, guarantee that transformer performance is stable, also can reach the sealing effectiveness of cable box simultaneously, prevent that rainwater and foreign material from entering and cause fault.

Embodiment
In the present embodiment, the utility model includes pivoted housing (1), thin hex nut (2), cover for seat (6) and adapter sleeve (4).Hypomere respectively is with fine thread on pivoted housing (1) outer surface, has thin hex nut (2) to be enclosed within pivoted housing (1) top and is threaded with pivoted housing (1), and the internal diameter of thin hex nut (2) is than the big 6mm of the outside diameter of cable.Cover for seat (6) inner wall belt fine thread, pivoted housing (1) bottom place in the cover for seat (6) and with cover for seat (6) inner thread and are connected.Cover for seat (6) bottom is a step perforate, and the size in hole is than the big 1mm of the outside diameter of cable, and pivoted housing (1) below has adapter sleeve (4) to place on the step of cover for seat (6), and adapter sleeve (4) is approximately an annulus, and its outer surface is the face of cylinder, 1: 3 tapering of inner surface belt.There is snap ring (7) to be affixed on the bottom surface of pivoted housing (1); snap ring (7) is that the bottom surface with specific glue and pivoted housing (1) is bonded together; snap ring (7) is made up of two half snap rings; snap ring (7) inner surface is the face of cylinder; 1: 3 tapering of outer surface belt; and match with adapter sleeve (4) inner surface, the peripheral rounding of snap ring (7) is to prevent that wedge angle crushes cable covering when fastening.Have seal cartridge (8) to place in snap ring (7) and the pivoted housing (1) and with the inner surface of snap ring (7) and pivoted housing (1) and fit, seal cartridge (8) is the rubber cylinder of a thick 2.5mm, high 40mm, when fastening cable is shielded.Pivoted housing (1) top is with seal washer (9), and seal washer (9) places between pivoted housing (1) and the cable box wall (11) cable box is sealed.Have ground strip (10) to play the ground connection effect between pivoted housing (1) and the seal washer (9), ground strip (10) is connected with the cable box current potential by bolt.
During use, pivoted housing (1) by the perforate of cable box base plate after and thin hex nut (2) tighten and be fixed on the cable box wall (11), cable passes the inner chamber of pivoted housing (1) and cover for seat (6), because pivoted housing (1) and cover for seat (6) link together by fine thread, when tightening cover for seat (6), cover for seat (6) drives on the adapter sleeve (4) and moves, adapter sleeve (4) by the cone match face with two snap rings (7) banding on cable, the area that surrounds between snap ring (7) dwindles, will compress cable, reach the effect of attached cable.The utility model is transferred to the power of outer bound pair cable on the cable box, and is not directly delivered to copper busbar by the cable that is fixedly clamped, and avoids causing the loosening of back panel wiring system, and is stable to guarantee transformer performance.
