Abstract
The utility model provides a clamp formula cable sheathing ground connection frame, includes a plurality of ground copper bars subassemblies of fixing on the wall body, its technical essential is: the ground copper bars subassembly includes the same ground copper bars unit I of a plurality of structures and ground copper bars unit II, establishes ties through the bridging copper bar between the adjacent ground copper bars unit I or between the ground copper bars unit II, ground copper bars unit I or ground copper bars unit II include the copper bar main part, with copper bar main part integrative a plurality of foots that are located the equidistant setting of copper bar main part bottom, be located the insulating piece at copper bar main part both ends, always to draw forth the copper bar fixed with same ground connection simultaneously for the homonymy of the ground copper bars subassembly that ground copper bars subassembly that ground copper bars unit I constitutes and ground copper bars unit II constitute, and the ground copper bars subassembly is fixed on the wall body through the expansion bolts who assembles on the insulating piece. Mounting means that fundamentally had solved cable shield layer ground connection is chaotic, unity is poor, interference immunity is poor, resistance uniformity subalternation problem.
Description
Technical field
The utility model relates to the installing area of cable or the electric wire protected with case, and be a kind of clamping hoop type cable cover(ing) grounding rack specifically, it is mainly applicable to signal cable shielding layer grounding in railway signal system.
Background technology
At present, the standard that in railway signal system, the mounting means of signal cable shielding layer grounding is ununified, in-site installation mode is chaotic, neat, the poor consistency of effect are installed, the steel first sheath of cable and aluminium sheath Grounding are not independently, protection for interference signal is disadvantageous, and earth lead is different in size, and cable shielding layer earthing resistance uniformity is bad.
Existing cable grounding device, if application publication number is the patent of invention of CN104821539A, it discloses " the invention discloses a kind of earthing box for electric cable ", comprise outer case, internal box is provided with in outer case, removably connect between internal box and outer case, outer case all has corresponding ventilation hole with on internal box, boss is provided with in internal box, boss is positioned on a bronze medal connecting rod, and boss bottom is connected on copper connecting rod, copper connecting rod two ends are fixed on internal box two medial surface, insulated terminal is provided with between copper connecting rod and boss, insulated terminal is fixed between copper connecting rod and boss, copper connecting rod lower surface is provided with connection copper bar, connect copper bar top to be connected with copper connecting rod one, be fixed on internal box inner bottom surface bottom it, internal box inner bottom surface is provided with protector detection of electrical leakage sound prompt device.
If Authorization Notice No. is the patent of invention of CN101938088B, it discloses " a kind of compact intelligent sealed insulating permanent magnetic vacuum ring main unit ", it has cabinet, in cabinet, latter half upper, middle and lower is provided with outgoing line device, lower outgoing line device and earthed switch, wherein go up tipping in outgoing line device and have three solid insulated busbars, three solid insulated busbars stretch out cabinet outside; In cabinet, the corresponding outgoing line device up and down of first half is provided with handcart type vacuum circuit breaker; The front plate of cabinet is provided with intelligent controller.
Utility model content
The purpose of this utility model is to provide a kind of clamping hoop type cable cover(ing) grounding rack.Fundamentally solve the mounting means confusion of cable shielding layer earthing, poor consistency, the steel first sheath of cable and aluminium sheath Grounding dependent and the problems such as the anti-interference caused is poor, the uneven in length cable shielding layer earthing resistance uniformity difference caused of earth lead are set.
The purpose of this utility model is achieved in that this clamping hoop type cable cover(ing) grounding rack comprises some grounding copper bar assemblies be fixed on body of wall, its technical essential is: described grounding copper bar assembly comprises the identical grounding copper bar unit I of some structures and grounding copper bar unit II, is adjacently connected by bridge joint copper bar between copper bar unit I or between grounding copper bar unit II; Grounding copper bar unit I or grounding copper bar unit II comprises copper bar main body, the some foots arranged at equal intervals being positioned at copper bar bottom part body with copper bar main body one, the insulating trip that is positioned at copper bar main body two ends; The homonymy of the grounding copper bar assembly that grounding copper bar unit I is formed and the grounding copper bar assembly that grounding copper bar unit II is formed always is drawn copper bar with same ground connection simultaneously and is fixed, and grounding copper bar assembly is fixed on body of wall by the expansion bolt be assemblied on insulating trip.
Good effect of the present utility model is: each assembly is all detachable, and clip (larynx hoop) can change the cable adapting to different thicknesses flexibly, and be convenient to transport and install, main body framework is fixed on body of wall by expansion bolt, sound construction.Installation effect is elegant in appearance, and cable line is installed firmly, marshalling, is convenient to standardized construction.The steel first sheath of cable and aluminium sheath are fastened on different copper bar unit blocks respectively by larynx hoop, make the Grounding of the two separate, are beneficial to protection interference signal, finally cause ground wire by rack common bus.Mounting means is more firm, and neatly, and cable shielding layer earthing resistance uniformity is good.

Fig. 3 is structural representation such as side-looking such as axle such as grade of the present utility model.
Description of reference numerals: 1 grounding copper bar unit I, Bridge 2 connect copper bar, 3 insulating trips, 4 grounding copper bar unit II, 5 ground connection always draw copper bar, 6 expansion bolts.
Embodiment
Below in conjunction with Fig. 1 ~ 3, describe content of the present utility model in detail by specific embodiment.This clamping hoop type cable cover(ing) grounding rack comprises some grounding copper bar assemblies be fixed on body of wall, grounding copper bar assembly comprises the identical grounding copper bar unit I1 of some structures and grounding copper bar unit II4, is adjacently connected by bridge joint copper bar 2 between copper bar unit I1 or between grounding copper bar unit II4.Grounding copper bar unit I1 or grounding copper bar unit II4 comprise copper bar main body, with being positioned at the some foots arranged at equal intervals of copper bar bottom part body, being positioned at the insulating trip 3 at copper bar main body two ends of copper bar main body one.The homonymy of the grounding copper bar assembly that grounding copper bar unit I1 is formed and the grounding copper bar assembly that grounding copper bar unit II4 is formed always is drawn copper bar 5 simultaneously and is fixed with same ground connection, grounding copper bar assembly is fixed on body of wall by the expansion bolt 6 be assemblied on insulating trip 3.During use, cable inner layer metal sheath is fixed on by larynx hoop in the foot of the grounding copper bar assembly that grounding copper bar unit I1 is formed, cable outer layer metallic sheath is fixed in the foot of the grounding copper bar assembly that grounding copper bar unit II4 is formed by larynx hoop, makes the Grounding of the two separate.
