Abstract

The utility model discloses a lightning-protection ground clamp capable of reducing cost, and the clamp comprises a connection antenna device, a ground cable, and a connection ground device. The connection antenna device comprises a clamp body, a first short heat shrink tube, and a first wiring terminal. One end of the first short heat shrink tube is connected with the first wiring terminal which is connected with the clamp body. The connection ground device comprises a second short heat shrink tube, a second wiring terminal, and a bolt group. The second short heat shrink tube is connected with the second wiring terminal. The bolt group is connected into a connection hole of the second wiring terminal. The ground cable is connected with the first short heat shrink tube and the second short heat shrink tube. The clamp body is made of three layers of materials, and comprises an inner clamp body layer, a clamp body interlayer, and an outer clamp body layer. The inner clamp body layer is made of aluminium materials, the clamp body interlayer is made of copper materials, and the outer clamp body layer is made of tin materials. The clamp provided by the utility model reduces the production cost, effectively prevents copper from oxidation and corrosion, and increases contact resistance of the ground clamp.

Description

A kind of lightning grounding clip reduced costs

Technical field

The utility model relates to communication grounding technology field, relates in particular to a kind of lightning grounding clip reduced costs.

Background technology

In the weather of storm accompanied by peals of thunder, outdoor antenna is easy to suffer the attack of thunder and lightning, and then causes the indoor electric appliance that the antenna other end connects to damage.In order to prevent that indoor electric appliance is struck by lightning, must be on antenna an earth connection in parallel.

Earth clip be for outdoor the material be connected of arranging.

The earth clip used at present includes: one connects antenna assembly, a grounding cable and a connection earthing bar device, wherein connects antenna assembly and comprises clamp, and the material of clamp of the prior art is all used red copper (T2 copper) mostly.

Red copper is purer a kind of copper, generally can be similar to and think fine copper, and conductivity, plasticity are all better, but intensity, hardness are more weaker.Red copper has good Dao Re ﹑ ductility and corrosion resistance.The market price of red copper is higher, to the high expensive that makes the red copper earth clip.

The utility model content

The lightning grounding clip that provides a kind of scope of application to reduce costs widely is provided the purpose of this utility model.

To achieve these goals, the lightning grounding clip reduced costs that the utility model provides comprises: one connects antenna assembly, a grounding cable and a connection earthing bar device; Connecting antenna assembly comprises: clamp, the first pyrocondensation short tube and the first binding post, and the first pyrocondensation short tube one end connects the first binding post, and the first binding post is connected with clamp; Connecting the earthing bar device comprises: the second pyrocondensation short tube, the second binding post and bolt group, and the second pyrocondensation short tube is connected with the second binding post, and the bolt group is connected in the connecting hole of the second binding post; Grounding cable connects respectively the first pyrocondensation short tube and the second pyrocondensation short tube; Wherein, clamp is the card that trilaminate material is made, and is respectively clamp internal layer, clamp intermediate layer and clamp skin, and the clamp internal layer is aluminium, clamp intermediate layer copper, and the clamp skin is tin.

In some embodiments, the copper in clamp intermediate layer is plated on the aluminium surface of clamp internal layer, and the outer field tin of clamp is plated on the copper surface in clamp intermediate layer.

The lightning grounding clip reduced costs of the present utility model compared with prior art, has the following advantages:

1. the lightning grounding clip reduced costs of the present utility model, its clamp adopts aluminium copper coating to replace original pure red copper material, has reduced production cost.

2. the lightning grounding clip reduced costs of the present utility model, be coated with one deck tin material on the copper surface, effectively prevents copper oxidation, corrosion, and increase the contact resistance of earth clip.

The accompanying drawing explanation

The structural representation of the lightning grounding clip reduced costs that Fig. 1 is a kind of execution mode of the utility model.

The structural representation that Fig. 2 is clamp in the lightning grounding clip reduced costs shown in Fig. 1.

The cutaway view that Fig. 3 is A part in the clamp shown in Fig. 2.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail to explanation.

Fig. 1 to Fig. 3 has schematically shown the lightning grounding clip reduced costs according to a kind of execution mode of the utility model.

As shown in Figure 1, the lightning grounding clip reduced costs of the present utility model comprises: a connection antenna assembly 1, a grounding cable 2 and have connected l earthing bar device 3;

As shown in Figure 1, connecting antenna assembly 1 comprises: clamp 101, the first pyrocondensation short tube 102 and the first binding post 103, the first pyrocondensation short tube 102 1 ends connect the first binding post 103, the first binding posts 103 and are connected with clamp 101.Connecting earthing bar device 3 comprises: the second pyrocondensation short tube 301, the second binding post 302 and bolt group 303, the second pyrocondensation short tubes 301 are connected with the second binding post 302, and bolt group 303 is connected in the connecting hole of the second binding post 302.Grounding cable 2 connects respectively the first pyrocondensation short tube 102 and the second pyrocondensation short tube 301.

As shown in Figures 2 and 3, the card that clamp 101 is made for trilaminate material, be respectively clamp internal layer 1011, clamp intermediate layer 1012 and clamp skin 1013, and clamp internal layer 1011 is aluminium, clamp intermediate layer 1012 bronze medals, and clamp outer 1013 is tin.The copper in clamp intermediate layer 1012 is plated on the aluminium surface of clamp internal layer 1011, and the tin of clamp skin 1013 is plated on the copper surface in clamp intermediate layer 1012.

In sum, the lightning grounding clip reduced costs of the present utility model, its clamp adopts the aluminium copper coating to replace original pure red copper material, has reduced production cost; In addition, on the copper surface, be coated with one deck tin material, effectively prevent copper oxidation, corrosion, and increase the contact resistance of earth clip.
