Abstract
The utility model relates to a signal lightning protection box, which is used for signal lightening protection of a railway vehicles running safe monitoring system detecting station. The signal lightning protection box comprises a box body, a PCB board, a wiring terminal, a signal surge protector and a lightening protection grounding bolt, wherein the PCB board is provided with a guide rail and is fixedly mounted on the middle portion of the box body, and the signal surge protector is mounted on the guide rail; an input end and an output end of the signal surge protector are connected with the wiring terminal mounted on a rear board of the box body through signal lines; and lightening protection ground wires are pressed on lighting protection ground of the signal surge protector, and the lighting protection ground wires are connected with the lighting protection grounding bolt arranged on the rear board of the box body after being gathered on the PCB board.
Description
Technical field
The utility model relates to a kind of signal lighting protection case, is used for the signal lighting protection protection of rolling stock operation safety monitoring system acquisition station.
Background technology
Existing signal lighting protection case is a drawer type subrack signal lighting protection case; signal lighting protection case outside is the cuboid casing; the box house side is equipped with guide rail; extracting box is installed on the guide rail; can pull out, advance; the signal surge protector is installed on the extraction box by being fixed on the guide rail that extracts on the box plate, and the lightning protection ground wire of each signal surge protector is welded on the copper bar that extracts the box bottom, and copper bar is electrically connected by the earth stud on welding lead and the signal lighting protection case backboard.The incoming line of signal surge protector, output line directly and the backboard of signal lighting protection case be electrically connected reliably.Its defective is:
1. the signal lighting protection case is a drawer type, and guarantee to extract box can pull out smoothly, and signal lighting protection case back panel wiring needs long enough, and this will influence the lightning protection properties of signal lighting protection case, also can influence the signal transmission;
2. the lightning protection ground wire of signal surge protector is to gather on the base plate that extracts box; extract box and signal box casing mechanical connection is arranged; therefore when the signal lighting protection case when releasing lightning current, can cause the signal lighting protection box body charged, this can disturb rolling stock operation safety monitoring system signal.
The utility model content
The utility model is to provide a kind of signal lighting protection case of non-drawer type subrack, makes the signal surge protector to be pushed into and to pull out as drawer, has reduced the length of signal surge protector signal input and output lines.Can avoid simultaneously the signal lighting protection case when releasing lightning current, to cause the charged and interference that monitoring-controlling system signal is produced of casing.
For achieving the above object, the technical scheme that the utility model adopted is: described signal lighting protection case is made up of casing, pcb board, binding post, signal surge protector and lightning protection bolt; Described pcb board is fixedly mounted on the centre position of casing, is equiped with guide rail on the pcb board, and the signal surge protector is installed on the guide rail; The input of described signal surge protector links to each other with the binding post that is installed on after panel box by holding wire with output; Crimping lightning protection ground wire on the lightning proof ground of described signal surge protector, described lightning proof ground line are summarized in pcb board and link to each other with the lightning protection bolt that is installed in after panel box.Described pcb board is an epoxy resin board.When surge protector when releasing lightning current, lightning current can not released on the casing, therefore will can not influence the signal that is installed in equipment in the same rack.
Compared to existing technology, the beneficial effects of the utility model are:
1. the signal surge protector is fixed on the middle pcb board of signal lighting protection case; the signal surge protector needn't be pushed into, pull out as drawer; reduced the length of the input of signal surge protector signal, output line; therefore reduced the impedance of conductor strip, also reduced the influence of lead lightning protection properties to the signal transmission.
2. the lightning protection ground wire of signal lighting protection case is to gather on pcb board, pcb board is fixed on the casing, and PCB insulate, therefore when the signal lighting protection case when releasing lightning current, can not cause the signal lighting protection case charged, can not interfere with the signal of rolling stock operation safety monitoring system.
Description of drawings
Fig. 1 is the structural representation of signal lighting protection case described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, signal lighting protection case described in the utility model is made up of casing 1, pcb board 2, binding post 4, signal surge protector 6 and lightning protection bolt 3.Pcb board 2 is fixedly mounted on the centre position of casing 1, is equiped with guide rail 5 by bolt on the pcb board 2, and signal surge protector 6 is stuck on the guide rail 5.Input, the output of signal surge protector 6 are crimped with holding wire, and the binding post 4 on the other end of holding wire and the casing 1 back plate is electrically connected reliably.Be crimped with the lightning protection ground wire on the lightning proof ground of signal surge protector 6; the other end of lightning protection ground wire is welded on the pcb board 2, and pcb board 2 is electrically connected the lightning proof ground congruence General Logistics Department of all signal surge protectors 6 and the lightning protection bolt 3 on the casing 1 back plate reliably.
When thunderbolt takes place when; induce lightning induced surge on the holding wire; lightning current is invaded protected equipment by the holding wire between signal surge protector 6 and the binding post 4; signal surge protector 6 begins action; carry out releasing of lightning current, lightning current is aggregated on the pcb board 2 by the lightning proof ground line of signal surge protector 6, and the lightning protection ground wire between pcb board 2 and lightning protection bolt 3 is released in the earth then; thereby that realizes lightning current releases protection equipment.Lead between signal surge protector 6 and the binding post 4 is short, helps reducing the impedance of signal transmission, help reducing the high frequency lightning current by the time induction overvoltage that produces.
Pcb board 2 is the epoxy resin board with casing 1 insulation, and when surge protector 6 was released lightning current, lightning current can not released on the casing 1, therefore will can not influence the signal that is installed in equipment in the same rack.
The utility model is not limited to the foregoing description; to those skilled in the art, any conspicuous improvement that the foregoing description of the present utility model is made or change can not exceed the embodiment of the present utility model that only illustrates by way of example and the protection range of claims.
