Description
Technical field
The present invention relates to a kind of lighting-proof branch means, especially relate to and a kind ofly the lightning prevention junction cabinet that lighting-proof branch base, band shielding and ground wire conflux is installed is used the lighting-proof branch assembled unit.
Background technology
One Chinese patent application numbers 200610060320.1 discloses a kind of lighting-proof branch means, comprises being provided with wire hole on substrate, terminal base, the substrate, and at least one separated time terminal base is set on the substrate, is electrically connected pluggable lightning-protection module on the separated time terminal base.One group of metallic shield is set into and out of wire casing on substrate, branch means is provided with the metallic shield cabinet outward, is provided with the ground connection copper bar at each separated time terminal base position, and forms common land line bus-bar.Separated time terminal base is the spring plug-in.Owing to adopt metallic shield wire casing, cabinet; And employing spring plug-in terminal base; Selection has the module of preventing misplug, lost efficacy demonstration, automatic shutoff circuit and send the lightning-protection module of remote signalling function; Realized that the turnover line divides the groove cabling, prevented the secondary pollution of electromagnetic interference and induction thunder.Its weak point is, because the lighting-proof branch base is installed on the insulating material substrate in the cabinet, base is installed the back and formed an integral body with the insulating material substrate, and lightning-protection module and separated time terminal are on a face, and area occupied is bigger, produces and install difficulty.And have the versatility problem, when equipment such as cabinet domestic demand installation testing dish, fuse, existing lightning prevention junction cabinet is difficult to realize.
At present, the high-speed railway engineering has proposed new requirement again to separated time capacity, the protection effect of lightning prevention junction cabinet, and existing lightning prevention junction cabinet is difficult to satisfy.Thereby, need the lightning prevention junction cabinet assembled unit of wanting a kind of standardized, highly versatile badly.Use the lightning prevention junction cabinet of assembled unit form not only can satisfy the requirement of high-speed railway engineering, can also reduce the quantity of lightning prevention junction cabinet, each layer can make things convenient for, configuration flexibly, and highly versatile has been saved space while of signal cabin, has also practiced thrift the railway construction cost.
Summary of the invention
The purpose of this invention is to provide a kind of lighting-proof branch assembled unit, solve separated time complex structure, dumb, the versatility difference problem of configuration that existing lighting-proof branch means exists.It has standardized structural, constitutes formant in the lightning prevention junction cabinet.Not only realized the isolation of lightning-protection module and separated time, improved the lightning protection effect, convenient simultaneously on-the-spot installation and maintenance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lighting-proof branch assembled unit, comprise laminate, lighting-proof branch base, shielding trough and connector, and at least one lighting-proof branch base is installed on the laminate; It is characterized in that: described lighting-proof branch base is the lighting-proof branch base that face-piece grafting lightning-protection module and drain pan connect the turnover line; Adaptive lighting-proof branch base is set on the described laminate embeds the exhausting hole that usefulness is installed, laminate is isolated the face-piece and the drain pan two sides of lighting-proof branch base; Shielding upward wiring groove, shielding downward cabling groove are set respectively up and down at the described laminate back side; The copper bar that confluxes of each lighting-proof branch base ground wire of parallel connection also is set in the described shielding downward cabling groove.
According to the function needs, installing hole, remote signalling through wires hole and the connection lighting-proof branch base connect with lightning prevention junction cabinet also is set on described laminate, shields trough, the installing hole of the copper bar that confluxes.
Further, described connection lighting-proof branch base, shield trough, the installing hole of the copper bar that confluxes is a shared hole.
On-the-spot for ease installation and maintenance, described shielding trough is provided with dismountable removable cover.
Further, also be provided with metal partion (metp) in the described shielding trough, form the two-layer wire casing that the turnover cable separately carries out Isolated Shield, the turnover cable is carried out Isolated Shield.
Good effect of the present invention: because the lighting-proof branch assembled unit has standardized structural; Flexible configuration, lightning-protection module are installed on the lighting-proof branch base face-piece, and binding post is installed on the drain pan of lighting-proof branch base; Realize separated time and shielding, constitute formant in the lightning prevention junction cabinet.Can not only satisfy jumbo separated time requirement, realize the isolation of lightning-protection module and separated time, improve the lightning protection effect, convenient simultaneously on-the-spot installation and maintenance.Maximum characteristics are to form a standardized lighting-proof branch to use assembled unit, realize that lightning protection and separated time are integrated.
Below will combine accompanying drawing and embodiment, the present invention will be carried out comparatively detailed explanation.
