Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples, the composition represented by example below it is complete
Portion's content is not limited to necessary to the solution as the utility model described in claim.
See Fig. 1, Fig. 2 and Fig. 3, metal hose earth protective device of the present utility model, with insulating sheath pipe 2, two
Individual end metal sheath 3, binding post 4, earth stud 5, cable 6, two panels ground connection packing ring 7 and grounding nut 8, insulating sheath
Pipe 2 is set in the outside of metal hose 1, and two end metal sheaths 3 are separately mounted to the two ends of metal hose 1, binding post 4
It is riveted on one of end metal sheath 3 by earth stud 5, one end of cable 6 is connected with binding post 4, electricity
The other end of cable 6 is connected with external ground device, and external ground device is electronic box or electric cabinet etc..
Wherein, each end of metal hose 1 is respectively provided with thread-like structure 1-1, is opened up on each end metal sheath 3
There is the thread groove 3-1 matched with thread-like structure 1-1, two end metal sheaths 3 are respectively screw and are connected to metal hose 1
Two ends.
Metal hose 1 uses P3 type galvanized metal flexible hoses, during metal hose is modern industrial equipment connecting pipeline
Important composition part, metal hose is mainly used as the electric wire protection pipe of electric wire, cable, instrument and meter for automation signal.
Insulating sheath pipe 2 carries out insulation protection to the surface of metal hose 1, and insulating sheath pipe 2 is by PVC plastic or glass fibers
Dimension etc. is made.
Two end metal sheaths 3 are made up of the relatively good metal of the electric conductivity such as aluminium alloy, copper or iron.
Step on 4 installed therein end metal sheaths 3 of binding post is：First by the screw rod of earth stud 5
Worn to outside from the endoporus of end metal sheath 3, and be arranged binding post 4, two panels successively on the extension of screw rod
, finally be tightened in grounding nut 8 on screw rod by ground connection packing ring 7 and grounding nut 8.
The metal hose earth protective device assembling when, without the insulating sheath pipe 2 destroyed outside metal hose 1,
Binding post 4 is directly riveted on one of end metal sheath 3 by earth stud 5, and number of assembling steps is simple, is grounded,
And convenient use.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
