Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and fig. 2, the present invention provides a lightning protection grounding device for photoelectric cable, wherein fig. 1 is a front view of the preferred embodiment of the lightning protection grounding device for photoelectric cable, and fig. 2 is a side view of the preferred embodiment of the lightning protection grounding device for photoelectric cable.
As shown in fig. 1 and 2, in the present embodiment, the photoelectric cable includes a cable armor layer 1, and a cable jacket layer 2 located at an outer periphery of the cable armor layer 1.
Lightning protection earthing device for photoelectric cable include with the first crimping piece 3 that cable armor 1 laminated mutually is located respectively the both ends of first crimping piece 3, and with cable sheath 2 fixed connection's second crimping piece 4 and third crimping piece 5, all be provided with jack catch 6 on second crimping piece 4 and the third crimping piece 5, be provided with the contact 7 that is used for connecting external connecting wire on the first crimping piece 3.
Wherein, as an embodiment, the first connecting piece is cylindrical, and the second crimping piece 4 and the third crimping piece 5 are conical.
One end of the connecting wire is connected with the contact, and the other end of the connecting wire is grounded.
In this embodiment, adopt 6 crimping structures of jack catch, be convenient for mill's prefabrication or site operation to installation convenience nature and flexibility have been promoted.
Specifically, during installation, the cable sheath layer 2 is firstly girdled and stripped, the stripping distance is as long as that of the first crimping piece 3, the first crimping piece 3 is directly pressed into a sheath groove (namely a girdling stripping part), so that the first crimping piece 3 is tightly attached to the cable armor layer 1, and the first crimping piece 3 and the cable armor layer 1 are pressed tightly by using crimping pliers; then, the second crimping piece 4 and the third crimping piece 5 are fixedly crimped with the cable sheath layer 2 through the clamping jaws 6; and finally, the third crimping piece 5 is grounded through the connecting wire and is wound by an insulating electrical tape to prevent electric leakage.
Further, as an embodiment, in the present embodiment, the cable armor 1, the first crimp member 3, the second crimp member 4, and the third crimp member 5 are made of stainless steel.
In view of the fact that the existing cable armor layer is made of stainless steel material, the lightning protection device in the prior art usually adopts copper material, and different materials are contacted to generate electrochemical corrosion, therefore, in order to solve the technical problem, the cable armor layer 1, the first crimping member 3, the second crimping member 4 and the third crimping member 5 in the lightning protection grounding device for the photoelectric cable provided by the embodiment all adopt the same stainless steel material as the cable armor layer 1. In addition, because the cost of stainless steel is lower than that of copper, the technical problem of electrochemical corrosion is avoided and the production cost is reduced by adopting the stainless steel material in the embodiment.
It should be noted that, in this embodiment, the number, the width, the length, and the shape of the claws 6 are not specifically limited, and may be determined according to actual needs in specific implementation. After being compressed tightly by the clamping jaw 6, the cable sheath layer 2 is rigidly connected, so that the problem of electric leakage caused by slippage of the sheath can be effectively avoided.
In addition, during specific implementation, the contact 7 can adopt an extension type structural design, the extension part is convenient for ground protection on site, and the assembly package is not required to be disassembled on site and can be directly assembled.
To sum up, the utility model discloses lightning grounding device for photoelectric cable passes through above-mentioned technical scheme, include with the first crimping piece that the cable armor laminated mutually is located respectively the both ends of first crimping piece, and with cable jacket layer fixed connection's second crimping piece and third crimping piece, all be provided with the jack catch on second crimping piece and the third crimping piece, be provided with the contact that is used for connecting external connecting wire on the third crimping piece, for prior art, it is more convenient nimble to install, and has reduced manufacturing cost.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
