Abstract
A kind of metal catheter connects cross-over connection earthing device, belongs to electrical engineering technical field, is specifically related to a kind of grounding apparatus.The metal catheter at threaded connector two ends arranges grounding clamp, and the end of grounding clamp arranges fixed bolt hole, set bolt through fixed bolt hole, by grounding clamp and metal catheter fastening, cross-over connection earth lug is set between grounding clamp.This device can carry out cross-over connection ground connection to metal catheter junction, has structure simple, easy construction, with low cost, adds the reliability of engineering, degree of safety.
Description
Technical field
The utility model belongs to electrical engineering technical field, is specifically related to a kind of grounding apparatus.
Background technology
Specify in existing related electric engineering construction, acceptance specification: reliably, current metal catheter connects cross-over connection earthing device for the necessary ground connection of conduit of metal or connecting to neutral, at joint both sides metal catheter respectively with bolt dead earth card crimping annealed copper wire.Non-zinc-plated metal catheter many employings round steel or band steel weld as cross-over connection earth connection respectively in joint both sides.Its shortcoming is that operation is more, lost labor, affect speed of application, and in work progress annealed copper wire be subject to external force impact fracture or crimping place come off, round steel or band steel welding affect larger by operative's water bottle, quality control acquires a certain degree of difficulty, outdoor connection to switch cross-over connection earth connection junction corrosion phenomenon serious, cause cross-over connection earth connection to perform practically no function.
Summary of the invention
The purpose of this utility model is to provide a kind of metal catheter and connects cross-over connection earthing device, to solve the deficiency that prior art exists.
The utility model is primarily of metal catheter and threaded connector composition, solving the technical scheme that its technical problem adopts is: the metal catheter at threaded connector two ends arranges grounding clamp, the end of grounding clamp arranges fixed bolt hole, set bolt is through fixed bolt hole, by grounding clamp and metal catheter fastening, cross-over connection earth lug is set between grounding clamp.
Described grounding clamp is U-shaped structure.
Described grounding clamp and cross-over connection earth lug are structure as a whole.
Distance between two fixed bolt holes after described grounding clamp stretches is consistent with the outer wall girth of metal catheter.
Adopt good effect of the present utility model to be: this device can carry out cross-over connection ground connection to metal catheter junction, there is structure simple, easy construction, with low cost, add the reliability of engineering, degree of safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model grounding clamp.
1 fixed bolt hole, 2 metal catheters, 3 grounding clamps, 4 cross-over connection earth lugs, 5 threaded connectors, 6 set bolts in figure.
Embodiment
As shown in the figure: the metal catheter 2 at threaded connector 5 two ends installs grounding clamp 3, the end of grounding clamp 3 has fixed bolt hole 1, set bolt 6 through fixed bolt hole 1, by grounding clamp 3 and metal catheter 2 fastening, between two grounding clamps 3, cross-over connection earth lug 4 is set.
Described grounding clamp is U-shaped structure.
Described grounding clamp and cross-over connection earth lug are structure as a whole.
Distance between two fixed bolt holes after described grounding clamp stretches is consistent with the outer wall girth of metal catheter.
