The utility model is characterized in that a sealing structure is arranged between the through hole at the sealed end of the housing and the conductor, which comprises a hollow boss coaxial to the through hole at the sealed end of the housing, a gland fixed firm to the boss and of a sealing ring which is positioned between the boss and the gland and which loops around the conductor. A sealing structure is also arranged between the housing and the base. The device has the advantages of preferable insulation, moisture-proof and dustproof performance, and easy assembly, low cost as well as wide application range.
Description
Technical field
The utility model relates to the sealing device of lead cable-through hole, is a kind of improvement technology of sealing device of lead cable-through hole specifically.
Background technology
At present, the connector place of lead, people are twined to reach the protection interface with empire cloth mostly, anti-principal vertical line unclamps exposes, the purpose of moistureproof and insulation, but this kind mode, its insulated enclosure effect is bad, the danger that electric leakage is arranged, and very easily get loose, if for the sort of need by on a pedestal, carry out the lead connector fixedly the time, the protected mode of this insulation and moisture just can't realize more; If lead enters another from the outside when needing airtight space, the sealing property of the dustproof grade of protection against the tide of the through hole that this place lead is passed has proposed requirement.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, lead is carried out lead when being connected and fixed on a pedestal, the through hole that when perhaps entering another and needing airtight space this place lead is passed have fine insulation and moistureproof dustproof effect be easy to assemble, cost is low, the sealing device of practical lead cable-through hole.
The utility model is achieved through the following technical solutions.
A kind of sealing device of lead cable-through hole, comprise pedestal, be fixed on the shell that an end open state other end seals on the pedestal, described closed termination of outer cover is provided with and runs through the through hole that connects lead, it is characterized in that: between through hole on the blind end of described shell and lead, be provided with hermetically-sealed construction, the sealing structure by with closed termination of outer cover on the coaxial cannular boss of through hole, be fastened on the gland on this boss and be arranged on boss and gland between and the sealing ring of ring set on lead constitute.
The two ends of described sealing ring are equipped with a taper surfaces of revolution, the hypotenuse of the taper surfaces of revolution tilts to the sealing ring lateral surface from end face, on the inside circumference wall of described boss through hole, be provided with the taper surfaces of revolution that is the pressure contact matching with the taper surfaces of revolution of sealing ring one end, on the inside circumference wall of described gland, be provided with the taper surfaces of revolution that is the pressure contact matching with the taper surfaces of revolution of the sealing ring other end.
Described gland is that screw threads for fastening is connected with boss on the closed termination of outer cover.
Be provided with hermetically-sealed construction between described shell and the pedestal.
Described hermetically-sealed construction is made of sealing ring, and two end faces of sealing circle respectively and be the pressure contact matching between shell and the pedestal.
Be provided with an annular ledge on the outer peripheral face of described shell open end, the end face of this annular ledge contacts with an end force of sealing ring; Be provided with a boss on described pedestal, the end face of this boss contacts with the other end pressure of sealing ring.
Be connected for screw threads for fastening between the boss on described shell and the pedestal.
The utility model compared with prior art has the following advantages.
Since between through hole on the blind end of shell and lead, be provided with sealing device, sealing effectiveness had, thus can prevent that sealing, steam, dust etc. enter in the shell from this, thus the lead in the shell has been played protective effect.
Described again sealing device is by sealing ring, be arranged on boss and the gland formation that is fastened on the boss coaxial on the shell with through hole, the two ends of sealing ring are equipped with a taper surfaces of revolution, and on boss and gland, also be provided with the taper surfaces of revolution with matching, behind fastening gland, sealing ring is subjected to two ends taper surface active force is pressed on the lead madial wall of cushion rubber.Like this gland with sealing ring circumferentially and radially all roof pressure on shell and lead, make between through hole on the closed termination of outer cover and the lead to be in sealing state fully.The sealing effectiveness to the lead in the shell has been played in the setting of this structure better.
Be provided with a sealing ring again between shell and pedestal, the sealing ring ring set is on shell, and the two ends of sealing ring all are the pressure contact matching, makes the lead in the shell be in sealing state fully.So, no matter lead is to carry out lead to be connected and fixed on a pedestal, and the through hole that when still entering another and needing airtight space this place lead is passed need carry out protection against the tide and prevent dust and insulation processing, all has good effect.
Description of drawings
Fig. 1 is the structural representation of the sealing device of the utility model lead cable-through hole;
Fig. 2 is the sealing device vertical view of the utility model lead cable-through hole
Fig. 3 analyses and observe the structure for amplifying schematic diagram for the sealing device of the utility model lead cable-through hole along the A-A place.
Embodiment
Below in conjunction with accompanying drawing a kind of stage lighting of the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, the sealing device of lead cable-through hole comprise pedestal 3, are fixed on the shell 1 that an end opens wide, the other end seals on the pedestal 3.The blind end of shell 1 is provided with and can runs through the through hole that connects lead 4.Between through hole and lead 4, be provided with hermetically-sealed construction, the sealing structure by with closed termination of outer cover on the coaxial cannular boss 13 of through hole, be fastened on the gland 2 on this boss 13 and be arranged on boss 13 and gland 2 between and the sealing ring 5 of ring set on lead 4 constitute.The two ends of sealing ring 5 are equipped with the taper surfaces of revolution, and the hypotenuse of the taper surfaces of revolution tilts to the sealing ring lateral surface from end face.On the inside circumference wall of the through hole of boss 13, be provided with the taper surfaces of revolution that is the pressure contact matching with the taper surfaces of revolution of sealing ring 5 one ends.On the inside circumference wall of gland 2, be provided with the taper surfaces of revolution that is the pressure contact matching with the taper surfaces of revolution of sealing ring 5 other ends.Boss 13 on gland 2 and shell 1 blind end can also be that direct interference back-off is press-fitted connection for screw threads for fastening is connected certainly.
