Abstract
The utility model relates to a seal structure of a power cavity of an anti-explosive LED (Light-Emitting Diode) illumination lamp. The seal structure comprises a pressing part, a seal ring, a wiring plate and a wiring cavity wall. The cross section of the pressing part takes the shapes of a rectangle and a right-angled trapezoid, the long edges of the right-angled trapezoid and the rectangle are located on a same straight line, the cross section of the seal ring takes the shape of a right-angled triangle, one edge of the right-angled triangle is provided with a plurality of protruding ribs, the cross section of the wiring plate takes the shape of a rectangle, the upper corners of the wiring plate are chamfered, the wiring cavity wall is provided with a smaller step, the wiring plate is arranged on the step, the seal ring is placed on slopes of the chamfered corners of the wiring plate, and the pressing part presses the seal ring tightly. The seal ring deforms under the extrusion of the pressing part, the slope of the cross section of the seal ring is tightly combined with the slopes of the chamfered corners of the wiring plate, and the right-angled edge, with the protruding ribs, of the cross section of the seal ring is tightly combined with the wiring cavity wall, thus the role of sealing a circuit is played. The seal structure has the advantages of concise appearance, simple structure, reliable sealing, capability of being dismounted and mounted repeatedly, and the like.
Description
Technical field
The utility model provides a kind of hermetically-sealed construction of anti-explosion LED lighting power source cavity.
Background technology
The anti-explosion LED light fixture is gathered circuit, explosion-resistant enclosure, light source etc. in one usually; Under explosive gas atmosphere; Usually use fluid sealant that electric crossover board and wire connection cavity wall is bonding; The power source cavity that forms sealing fully gets into to prevent damp, makes the work that the circuit that is operated in the power source cavity can be safe and reliable, but this structure has that outward appearance is untidy, construction is inconvenient, need clear up shortcoming such as fluid sealant during dismounting.
Summary of the invention
To the problems referred to above, the utility model provides a kind of hermetically-sealed construction of simple in structure, easy accessibility.
The technical scheme of the utility model is: the invention provides a kind of hermetically-sealed construction of anti-explosion LED lighting power source cavity, comprise pressing section, sealing ring, terminal plate and wire connection cavity wall.
Described pressing section cross section comprises a rectangle and a right-angled trapezium, and the long limit of right-angled trapezium and rectangle is distributed with a plurality of holes on pressing section on same straight line.
Described sealing ring cross section is a right angled triangle, one side right angled triangle be provided with many prominent muscle, another right-angle side closely is connected with said pressing section, the hypotenuse that Vee formation shape is installed is parallel with said pressing section cross section right-angled trapezium hypotenuse.
Chamfering is done in rectangular and last corner, described terminal plate cross section, is distributed with both positive and negative polarity and earth terminal on the terminal plate, and the corresponding screwed hole that is distributed with the hole of said pressing section is provided with bellmouth between the screwed hole.
Described wire connection cavity wall is provided with less step, arranges boss and auger shell pit with the bellmouth correspondence position of said terminal plate on the wire connection cavity wall.
Described terminal plate is installed on the said wire connection cavity wall step, and said sealing ring is placed on the inclined-plane of terminal plate chamfering, and said pressing section compresses sealing ring.Sealing ring is out of shape under the squeezing action of pressing section, combines closely in the inclined-plane of the hypotenuse in sealing ring cross section and the chamfering of terminal plate, and the right-angle side and the wire connection cavity wall of the prominent muscle of sealing ring cross section band are combined closely, thereby plays the effect of sealing.This structure has that outward appearance is clean and tidy, simple in structure, sealing is reliable, can repeat advantage such as dismounting
