Abstract
The invention relates to a waterproof insulating head, which comprises an upper insulating head, an upper rain cover, a spring base, a lower telescopic head and a lower rain cover, wherein two rain covers are arranged; the upper rain cover is used for preventing rainwater from entering a protector along an electric wire; the lower rain cover can be used for preventing the rainwater from being blown into the protector by external high wind; and meanwhile, the telescopic insulating head automatically protects an exposed joint, so that a human body is insulated from the exposed joint; and low-voltage live working is achieved.
Description
Technical field
The present invention relates to a kind of insulative head, particularly relate to a kind of waterproof insulation head.
Background technology
Insulative head of the prior art, only arranges protective cover, in low-voltage leakage protector, switch terminal
During number connections, protective action be there is no substantially for waterproof, the end of a thread insulation.When running into rainy, low pressure
The water inlet of earth leakage protective device point of incoming cables is serious, causes a large amount of low-voltage leakage protector malfunctioning or burns.
Summary of the invention
The present invention provides a kind of waterproof insulation head, uses telescopic insulating protection pipe, rain cover to carry out it
Protection.Decrease switch, protector because carrying out causing damage, simultaneous retractable formula insulating protection pipe pair
Line joint is protected automatically, decreases contacting of human body and exposed joint, it is possible to achieve depression belt
Electricity operation.In order to achieve the above object, the present invention adopts the following technical scheme that:
The waterproof insulation head of the present invention include insulative head, upper rain cover, spring pedestal, lower telescopic head with
And lower rain cover, described upper insulative head uses cable cold-shrink technology to be connected with wire, under described upper insulative head
There is tap in portion, uses with spring pedestal and is spirally connected.
Upper rain cover be mushroom hair style rain cover on described below insulative head at 1/3rd with described upper insulation
First melt is connected on one.
The upper inside wall of described spring pedestal has tap, is spirally connected with described upper insulative head, described
Being provided with strong plastic spring inside spring pedestal, strong plastic spring is for ejecting lower telescopic head, described
Spring pedestal lower inner wall has a circle internal ring limit.
Described lower telescopic head uses rigid plastics, and diameter is less than spring pedestal；At described lower telescopic head top
Having a circle outer annular edge, diameter is suitable with internal ring limit, described spring pedestal bottom, but less than inside spring pedestal
Diameter, when described lower telescopic head is ejected by spring, owing to lower telescopic head has an outer annular edge and spring pedestal
Internal ring limit, bottom diameter is suitable, therefore lower telescopic head is blocked by spring pedestal, makes lower telescopic head and spring pedestal
Cannot depart from.
Described lower rain cover uses mushroom hair style rain cover lower flexible with described at 1/3rd under lower telescopic head
First melt is connected on one.
The present invention uses two rain covers, and upper rain cover is used for preventing rainwater para-electric line water inlet protector, under
Rain cover is possible to prevent rainwater to be scraped by outside strong wind and enters protector into rainwater, and simultaneous retractable formula insulative head is certainly
The exposed joint of dynamic protection, makes human body and exposed splice insulation, it is achieved low-voltage live line work.
Accompanying drawing explanation
Fig. 1: waterproof insulation head overall structure figure；
Reference:
Waterproof insulation head 1, upper insulative head 2, upper rain cover 3, spring pedestal 4, lower telescopic head 5,
Lower rain cover 6.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, technical scheme is described further.
The waterproof insulation head (1) of the present invention includes at the bottom of insulative head (2), upper rain cover (3), spring
Seat (4), lower telescopic head (5) and lower rain cover (6), described upper insulative head (2) uses cable
Cold-shrink technology is connected with wire, and tap is arranged at described upper insulative head (2) bottom, with described spring pedestal (4)
Use spiral connection.
Upper rain cover (3) be mushroom hair style rain cover on described insulative head (2) lower section 1/3rd at
The welding of described upper insulative head (2) is in one.
The upper inside wall of described spring pedestal (4) has tap, spiral with described upper insulative head (2)
Connecting, described spring pedestal (4) is internal is provided with strong plastic spring, strong plastic spring for by under stretch
Drop-head (5) ejects, and described spring pedestal (4) lower inner wall has a circle internal ring limit, stretching under described
When drop-head (5) is ejected into described spring pedestal (4) bottom, described lower telescopic head (5) is blocked；Institute
Stating lower telescopic head (5) and use rigid plastics, diameter is less than spring pedestal (4)；Lower rain cover (6) is adopted
With mushroom hair style rain cover at lower telescopic head (5) bottom 1/3rd with the welding of described lower telescopic head (5)
In one, there are a circle outer annular edge, diameter and described spring pedestal (4) at described lower telescopic head (5) top
Internal ring limit, bottom is suitable, but less than spring pedestal (4) inside diameter, at spring by described lower telescopic head (5)
During ejection, due to described lower telescopic head (5) outer annular edge and internal ring limit, spring pedestal (4) bottom diameter phase
When, therefore described lower telescopic head (5) is blocked by described spring pedestal (4), makes described lower telescopic head (5)
Cannot depart from described spring pedestal (4).
Described upper insulative head (2) uses silastic material, and described spring pedestal (4) uses rigid plastics,
Described lower telescopic head (5) uses rigid plastics.
Above example only in order to technical scheme to be described, is not intended to limit, although with reference to front
Stating embodiment to be described in detail the present invention, those of ordinary skill in the art still can be to front
State the technical scheme described in each embodiment to modify, or wherein portion of techniques feature is equal to
Replace.And these amendments or replacement, do not make the essence of appropriate technical solution depart from the present invention and respectively implement
The spirit and scope of example technical scheme.
