Description
Technical field
The utility model relates to a kind of novel grounded line terminals, it is a kind of earthy line terminals being applicable to each specification power cable, the coaxial round shape communications cable such as RF cable and optical cable, relative to the earthy line terminals of tradition, this novel grounded line terminals is easy for installation, applied widely, ground connection performance is good.
Background technology
Earth connection in electric power system and communication system, one is that the equipment and circuit that prevent from having had a power failure unexpectedly occur voltage, and two is the capacitance voltage reliable grounds by the induced voltage on equipment or circuit or cable line, ensures equipment and personal security.Wherein earth connection terminal is one of most important product in whole ground path, whether solid and reliablely which determines grounding measures, ground connection whether safety.
At present, the earth connection terminal used in power cable or telecommunication cable, DT type, DTM type earth connection terminal or GT type tube connector in many employings standard GB/T14315-2008 " power cable conductor crimp type copper, aluminum connecting terminal and tube connector ".
The connected mode of DT type, DTM type earth connection terminal is connected with grounding apparatus by the punching of this line terminals with screw, plain cushion, nut, then screws up with a wrench.This earth connection terminal installs trouble, and poor reliability, contact area is limited, ground connection poor performance.
The connected mode of GT type tube connector is interconnected by close on two cable conductors by the mode of crimping.Because this tube connector is the mode with crimping, therefore can only be used for continuing of power cable, the ground connection for telecommunication cables such as coaxial RF cable and optical cables is inapplicable, and the scope of application is little, and the poor reliability of crimping.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, a kind of novel grounded line terminals is provided, be applicable to the earthy line terminals of each specification power cable, the coaxial round shape communications cable such as RF cable and optical cable, relative to the earthy line terminals of tradition, this novel grounded line terminals is easy for installation, applied widely, ground connection performance is good.
The technical solution of the utility model is:
A kind of novel grounded line terminals, comprises pipe box 1 and inner wire connecting plate 2, and pipe box 1 and inner wire connecting plate 2 are an entirety, this entirety adopts copper pipe to make, obtain inner wire connecting plate 2 through pressing, inner wire connecting plate 2 is provided with card key 3, and card key 3 is obtained by shaping and stamping-out.
Described pipe box 1 is directly crimped with the inner wire of the power cable peelling off insulating barrier by Press Plier or press-connection machine.
The cross section of described inner wire connecting plate 2 is circular arc.
Described card key 3 crimps with copper braid over braid 4.
The beneficial effects of the utility model are:
The novel grounded line terminals of one of the present utility model has the advantages such as easy for installation, applied widely, ground connection performance is good.Ground connection performance index of the present utility model meet and are better than the requirement in standard GB/T14315-2008 " power cable conductor crimp type copper, aluminum connecting terminal and tube connector " and communication industry standard YD/T2339.2-2011 " radio frequency coaxial-cable lays and uses annex part 2: grounding clamp ".
Accompanying drawing explanation
Fig. 1 is side structure schematic diagram of the present utility model.
Fig. 2 is front of the present utility model scheme of installation.
Fig. 3 is along B-B direction cutaway view in Fig. 2.
In figure: 1 be pipe box, 2 be inner wire connecting plate, 3 be card key, 4 for copper braid over braid.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As Fig. 1 to 3, a kind of novel grounded line terminals, comprises pipe box 1 and inner wire connecting plate 2, pipe box 1 and inner wire connecting plate 2 are an entirety, and this entirety adopts copper pipe to make, and obtain inner wire connecting plate 2 through flattening, inner wire connecting plate 2 is provided with card key 3, and card key 3 is obtained by shaping and stamping-out.
The copper pipe of different size diameter can be selected to make according to the sectional area of the power cable of different size, applied widely, easy for installation.
Pipe box 1 is directly crimped with the inner wire of the power cable peelling off insulating barrier by Press Plier or press-connection machine.
After power cable peels off insulating barrier, inner wire inserts in the pipe box 1 of this novel grounded line terminals one end, and directly can crimp with Press Plier or press-connection machine, crimp strength is high, and reliability is high.
The cross section of inner wire connecting plate 2 is circular arc.The circular arc of this novel grounded line terminals one end can with the communications cable inner wire close contact of the round shape such as the power cable of each specification, coaxial RF cable and optical cable, contact-making surface is large, and ground connection performance is good.
Card key 3 crimps with copper braid over braid 4.This novel grounded line terminals has two card keys, can crimp with copper braid over braid 4, then copper braid over braid is wrapped on power cable, the coaxial round shape communications cable inner wire such as RF cable and optical cable, and wrap up with waterproof clay and adhesive tape, add contact-making surface, ground connection performance is better.
Embodiment recited above is only be described preferred implementation of the present utility model; not design of the present utility model and scope are limited; do not departing under the utility model design concept prerequisite; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement; all should fall into protection range of the present utility model, the technology contents of the utility model request protection is all recorded in detail in the claims.
