Abstract
Metal connection, mainly by the metal wire box, metal conduit and cross -over connection ground connection mechanism group become, characterized by cross -over connection ground connection mechanism includes ground connection card and cross -over connection earth lug, the ground connection card sets up on metal conduit, ground connection card end sets up the fixing bolt hole, fixing bolt passes the fixing bolt hole with ground connection card and metal conduit fastening, set up the cross -over connection earth lug between ground connection card and metal wire box, cross -over connection earth lug end sets up the fixing bolt hole, fixing bolt passes the fixing bolt hole with cross -over connection earth lug and the fastening of metal wire box. The utility model discloses the device can carry out cross -over connection ground connection with line box junction to metal conduit, has simple structure, construction convenience, low cost, easy batch production's characteristics, has increased the reliable degree and the degree of safety of engineering.
Description
Technical field
This utility model relates to electrical engineering grounding technology field, is specifically related to a kind of metal catheter and connects bridging grounding device.
Background technology
In existing related electric engineering construction, acceptance specification specify: cabinet, screen, platform, case, the metal framework of dish, metal conduit must ground connection or connecting to neutral reliable.Current metal catheter is connected bridging grounding device with line box (case), crimps annealed copper wire with bolt dead earth card respectively between galvanized metal conduit with line box (case)；Between non-zinc-plated metal catheter and line box (case), many employing round steel or band steel are respectively welded as bridging earth lead.Its shortcoming is that operation is more, lost labor, affect speed of application, and construct in annealed copper wire be subject to external force impact fracture or crimping place come off, round steel or band steel welding are affected bigger by operative's level, quality control acquires a certain degree of difficulty, and the conduit bridging earth lead junction corrosion phenomenon of outdoor connection is serious in addition, causes that bridging earth lead performs practically no function.
Utility model content
This utility model provides a kind of metal catheter and connects bridging grounding device, and to solve, using of prior art existence is loaded down with trivial details, ground connection quality control difficulty is big and the problem of outdoor seriously corroded.
This utility model is mainly made up of metal wire box, metal catheter and bridging earthing mechanism, solve its technical problem and be employed technical scheme comprise that bridging earthing mechanism includes grounding clamp and bridging earth lug, grounding clamp is arranged on metal catheter, grounding clamp end arranges fixed bolt hole, grounding clamp and metal catheter are fastened by fixing bolt through fixed bolt hole, bridging earth lug is set between grounding clamp and metal wire box, bridging earth lug end arranges fixed bolt hole, and fixing bolt will bridging earth lug and the fastening of metal wire box through fixed bolt hole.
Above-mentioned grounding clamp is U-shape structure.
Above-mentioned grounding clamp is structure as a whole with bridging earth lug.
The spacing of two fixed bolt holes after the stretching, extension of above-mentioned grounding clamp is consistent with the outer diameter of metal catheter.
Metal catheter and line box junction can be carried out bridging ground connection by this utility model device, have simple in construction, easy construction, with low cost, be prone to the feature of batch production, add reliability and the degree of safety of engineering.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the structural representation of this utility model device；
Fig. 2 is the structural representation of this utility model grounding clamp；
Fig. 3 is the planar development schematic diagram of this utility model bridging earthing mechanism.
1 metal wire box, 2 metal catheters, 3 grounding clamps, 4 fixing bolts, 5 fixed bolt holes, 6 bridging earth lugs in figure.
Detailed description of the invention
Such as Fig. 1, shown in Fig. 2 and Fig. 3, a kind of metal catheter connects bridging grounding device, main by metal wire box 1, metal catheter 2 and bridging earthing mechanism composition, bridging earthing mechanism includes grounding clamp 3 and bridging earth lug 6, grounding clamp 3 is arranged on metal catheter 2, grounding clamp 3 is U-shape structure, grounding clamp 3 end arranges fixed bolt hole 5, grounding clamp 3 and metal catheter 2 are fastened by fixing bolt 4 through fixed bolt hole 5, bridging earth lug 6 is set between grounding clamp 3 and metal wire box 1, grounding clamp 3 is structure as a whole with bridging earth lug 6, bridging earth lug 6 end arranges fixed bolt hole 5, bridging earth lug 6 and metal wire box 1 are fastened by fixing bolt 4 through fixed bolt hole 5.
