The insulation base (2) is equipped with a rectangular opening groove (21), wherein the cable bridge stand (1) is clamped and fixed in the opening groove (21). The lighting arrester has the advantages of good lightning-protection effects, low signal interferences, simple and convenient installation, and high construction efficiency.
Description
Technical field
The utility model relates to the wiring installation field, is specifically related to a kind of lightning arrester that is used for cable testing bridge.
Background technology
The intelligent building wiring installation relates to a large amount of weak electricity systems; Usually there is corresponding system such as a plurality of information monitorings and communications facility such as BA (building automatic), OA (office automation), CA (communication automation system) to form; Cable testing bridge is by formations such as the straightway of pallet or ladder, curved logical, assembly and trailing arm (arm-type support), suspension brackets, the rigid structure that cable testing bridge can carrying cable.For the wiring installation of standard building, be convenient to the wiring management, cable testing bridge has been widely used in the wiring installation of all kinds building at present.
Because the cable testing bridge environment of applications is very extensive,,, therefore attract thunder and lightning easily because cable testing bridge generally comprises a large amount of metal structures when appearing at outdoor the time.And when lightning rod was installed, because that lightning rod need be fixed on is architectural, therefore one side needed professional construction machinery, and percussion drill or the like for example also can influence the efficiency of construction of wiring installation on the other hand, causes cable testing bridge cable wiring manufacture excessive cycle.
Summary of the invention
The purpose of the utility model provides the lightning arrester that is used for cable testing bridge that a kind of lightning protection effect is good, the signal interference is low, installation is simple and convenient, efficiency of construction is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of lightning arrester that is used for cable testing bridge comprises the insulator foot that is clamped and fastened on the cable testing bridge, and said insulator foot is provided with the lightning rod of vertically arranging up, and said lightning rod is through lead ground connection; Said insulator foot is provided with the open slot of rectangle, and said cable testing bridge is clamped and fastened in the said open slot.
Further improvement as technique scheme:
The internal face of said open slot is provided with the metal level that is used for shielded signal, and said open slot is clamped and fastened on the said cable testing bridge through said metal level.
Said metal level and said lightning rod common ground.
The utlity model has following advantage:
The utility model comprises the insulator foot that is clamped and fastened on the cable testing bridge; Insulator foot is provided with the lightning rod of vertically arranging up, and lightning rod is through lead ground connection, and insulator foot is provided with the open slot of rectangle; Cable testing bridge is clamped and fastened in the open slot; Can realize the Fast Installation of lightning rod through insulator foot, can avoid thunder and lightning to hit cable testing bridge, have that lightning protection effect is good, signal disturbs the advantage low, that installation is simple and convenient, efficiency of construction is high through lightning rod.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 1, the lightning arrester that present embodiment is used for cable testing bridge comprises the insulator foot 2 that is clamped and fastened on the cable testing bridge 1, and insulator foot 2 is provided with the lightning rod of vertically arranging 3 up, and lightning rod 3 is through lead ground connection; Insulator foot 2 is provided with the open slot 21 of rectangle, and cable testing bridge 1 is clamped and fastened in the open slot 21.Present embodiment can avoid thunder and lightning to hit cable testing bridge 1 through 2 Fast Installation that can realize lightning rod 3 in the insulation end through lightning rod 3, has the advantage that lightning protection effect is good, the signal interference is low, installation is simple and convenient, efficiency of construction is high.
The insulator foot 2 of present embodiment is provided with the metal internal thread hole, and the metal internal thread hole is connected conducting with earth terminal on the insulator foot 2, and 3 on lightning rod is threaded with the metal internal thread hole.
The internal face of the open slot 21 of present embodiment is provided with the metal level 4 that is used for shielded signal; Open slot 21 is clamped and fastened on the cable testing bridge 1 through metal level 4; Metal level 4 can play the effect of noise isolation to cable testing bridge 1 inner cable; Bad weathers such as generation thunder and lightning can improve the reliability of cable signal transmission, even also can effectively guarantee the reliability of cable.The metal level 4 and lightning rod 3 common grounds of present embodiment guarantee that metal level 4 is zero potential, and shield effectiveness is better.
The installation steps of present embodiment are following:
1) construction cable testing bridge 1.
2) after cable testing bridge 1 construction finishes, the open slot 21 of insulator foot 2 is sheathed on to cable testing bridge 1.
3) insert lightning rod 3 in the metal internal thread hole on the insulator foots 2 and tighten.
4) earth terminal on the insulator foot 2 is passed through plain conductor ground connection, installation, last effect sketch map is as shown in Figure 2.
The above is merely the preferred implementation of the utility model, and the protection range of the utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to the protection range of the utility model.For a person skilled in the art, some improvement and the retouching under the prerequisite of the principle that does not break away from the utility model, carried out, these improvement and retouching also should be regarded as the protection range of the utility model.
