The present invention relates to a lightning arrestor apparatus and, more particularly, to a lightning arrestor apparatus with lower transmission loss than the original design and good assembly to avoid moisture intrusion.
The lightning arrestor apparatus can rapidly leak abnormal high-voltage surge with several megavolt to the ground, which can avoid the power system being damaged. Upon said abnormal high-voltage disappears, a lightning arrestor apparatus will disconnect continuous current from the source to restore the OFF status.
The present inventors further analyze according to the usage response to find out the engaging means using the structure of conventional lightning arrestor apparatus and said coaxial cables (200) (300). Upon long-term using, bad assembly causes severe transmission loss of signal plus moisture intrusion to break owing to instantaneous pressure. Therefore, it is desirable to improve the structure of conventional lightning arrestor.
The purpose of present invention is to provide an improved lightning arrestor apparatus, which can directly transmit input signal to reduce transmission loss of said signal.
The other purpose of present invention is to provide a lightning arrestor apparatus, which can prevent bad assembly and moisture intrusion from causing a break owing to instantaneous pressure. Therefore, it can be used to protect internal components of said lightning arrestor apparatus and prevent damage.
In order to achieve the object, a lightning arrestor apparatus is created, which means are: a connecting piece including a first connecting end and a second connecting end on both sides of said connecting piece; a first coaxial cable including a first terminal to connect said first connecting end for transmitting signal; a second coaxial cable including a second terminal to connect said second connecting end for transmitting signal above-mentioned; and a grounding lead, which is installed under said connecting piece. The exteriors of said first terminal and said first connecting end have been further wrapped with a first protection coating. The exteriors of said second terminal and said second connecting end have been further wrapped with a second protection coating. Therefore, the effect of the present invention separately connects with the first terminal of first coaxial cable and the second terminal of second coaxial cable by means of both sides of said connecting piece that can more directly transmit the input signal to reduce transmission loss of said signal, which not only can wrap with first and second protection coating at the connecting part to enhance the assembly effect but also can prevent moisture intrusion from the explosion.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The contents and details of the present invention are described with drawings to list the concrete examples as follows:
Refer to
Said first coaxial cable (2) includes a first terminal (21) to connect with said first connecting end (11) for transmitting signal. The exteriors of said first terminal (21) and said first connecting end (11) are wrapped with a first protection coating (5).
Said second coaxial cable (3) includes a second terminal (31) to connect said second connecting end (12) for transmitting signal above-mentioned. The exteriors of said second terminal (31) and said second connecting end (12) are wrapped with a second protection coating (6).
Said grounding lead (4) is installed under said connecting piece (1). Said grounding lead (4) must be guided to on the side of metal exposed to the layer surface (not shown in figure) to connect so that can form lightning protection.
By means of structural combination above-mentioned, please refer to
1. The present invention can apply to computer network, video, telephone and monitoring equipment, so that can prevent said equipment from instantaneous surge or lightning strike to more directly transmit the input signal and achieve the effect of reducing transmission loss of said signal. When the present invention operates, the stability of circuit system for equipment above-mentioned will not be interfered with lesser power loss.
2. The present invention can enhance the assembly effect to prevent moisture intrusion from breaking owing to instantaneous pressure, which can protect internal components of said lightning arrestor apparatus from damaging and provide good protection.
