Abstract
The utility model discloses an air-tightness protection structure of an outer cavity in a cable, which is provided with a through hole that is arranged on a box body and provided with a thread, wherein the through hole is internally provided with a sealed collar in a clamping manner, a plurality of perforations for a cable to pass through are arranged on the sealed collar, a pressure ring matched with the thread of the through hole is arranged on the outer side of the sealed collar, and silicon rubber is filled among the through hole, the sealed collar and the pressure ring. Compared with the prior art, the air-tightness protection structure of the outer cavity in the cable has low cost, convenience in manufacturing and good air tightness, the cable is not easy to wear and durable.
Description
Technical field
The utility model belongs to technical field of sealing technology, is specifically related to the tightness safeguard structure of exocoel in a kind of cable.
Background technique:
In production practices, run into and in an airtight case shell, put into the appliance device electric test operation of working of going forward side by side through regular meeting; require internal environment can charge into drying nitrogen protection atmosphere; outer chamber need carry out seal approach like this, about cable will penetrate body of wall energising and sealing.Standing state adopts valuable aviation socket to solve, and exists cost higher, and inconvenience is installed, the long-time phenomenon that occurs the insulation wearing and tearing easily, opens circuit of using.
The model utility content
For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of cost low, easy to make, and tightness is good, the tightness safeguard structure of exocoel in the long-lived cable.
For achieving the above object, the technical solution adopted in the utility model: the tightness safeguard structure of exocoel in this cable, has the screwed through hole that is arranged on the casing, it is characterized in that: be installed with sealing ring in the described through hole, described sealing ring is provided with the through hole that a plurality of cables pass through, the outside of sealing ring is provided with the trim ring that cooperates with through hole whorl, is filled with silicone rubber between described through hole, sealing ring and the trim ring.
Adopt the beneficial effect of technique scheme: the sealing ring of the tightness safeguard structure of exocoel is provided with the through hole that a plurality of cables pass through in this cable, keep passing through inside and outside the cable, utilize the silicone rubber seal material seal and tighten up cable, reach sealing and energising function.The outside of sealing ring is provided with the trim ring that cooperates with through hole whorl, trim ring compresses sealing ring, and can fully compress the silicone rubber that is positioned at the junction plane place, silicone rubber can fully be filled the gap between each part, can play seal action after solidifying through 24 hours silicone rubber, reach the effect of good gas tightness and firm cable.Compared with prior art, it is low, easy to make to have a cost, and tightness is good, and cable is not easy wearing and tearing, and is durable in use.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The tightness safeguard structure of exocoel in the cable as shown in Figure 1, has the screwed through hole 4 that is arranged on the casing 1, be installed with sealing ring 5 in the described through hole 4, described sealing ring is provided with the through hole that a plurality of cables 3 pass through, and through hole is according to cable diameter and quantity setting.The outside of sealing ring 5 is provided with the trim ring 2 that cooperates with through hole whorl, is filled with silicone rubber 6 between described through hole, sealing ring and the trim ring.During assembling, cable is passed the through hole of sealing ring, charge into silicone rubber 6, compress sealing ring 5, can play seal action after solidifying through 24 hours silicone rubber, reach the effect of good gas tightness and firm cable with threaded ring 2.
