Abstract
The utility model relates to a signal reproduction distributing box. The signal reproduction distributing box comprises an upper casing, a lower casing, an upper PCB (printed circuit board), and a lower PCB, wherein a pin header is fixed on the upper PCB; a female header corresponding to the pin header is fixed on the lower PCB; single-row one-column Coaxial interfaces are fixed on the upper PCB; single-row one-column Coaxial interface are also fixed on the lower PCB; a SCSI (small computer system interface) interface is respectively fixed on the upper PCB and the lower PCB; holes for mounting the SCSI interface and the Coaxial interfaces are formed on the upper casing; and the upper casing, the upper PCB, the lower PCB and the lower casing are fixed together through screws. According to the utility model, the single-row one-column Coaxial is used to substitute for the conventional double-row two-column Coaxial, two PCBs are used to transmit coaxial cable signals, and the two PCBs connected through a connector so as to transmit signals between the two PCBs. Accordingly, the single reproduction distributing box provided by the utility model can realize the same function of the conventional product using double-row two-column Coaxial, thereby saving a large amount of cost.
Description
Technical field
The utility model relates to a kind of distributing box, particularly relates to a kind of simple in structurely, can realize original function, can practice thrift the signal replication distributing box of great amount of cost.
Background technology
The present existing signal replication distributing box in market, mainly be through double two connect Coaxial the veneer PCB layout realize and scsi interface between the signal transmission, this interface uses inconvenient, does not also practice thrift cost simultaneously.
SCSI-small computer system interface (Small Computer System Interface) is kind of a comparatively special interface bus, possesses with polytype peripheral hardware to communicate.
On the SCSI bus, can connect host adapter and eight SCSI peripheral control units, peripheral hardware can comprise disk, tape, CD-ROM, erasable optical disk driver, printer, scanner and communication apparatus etc.
SCSI is a multitask interface, is provided with the bus arbitration function, and a plurality of peripheral hardwares that hang on the SCSI bus can be worked simultaneously, and the last equipment equality of SCSI is occupied bus.
Scsi interface can be synchronously or asynchronous transfer of data, and synchronous transmission speed can reach 10MB/s, and asynchronous transmission speed can reach 1.5MB/s.
The utility model content
To the problems referred to above; The main purpose of the utility model is to provide a kind of usefulness single one to connect even Coaxial of Coaxial alternative original double two; Realize the transmission of coaxial cable signal through two PCB; Signal between two PCB connects to come transmission signals through connector, realized and use double two connect the Coaxial identical functions the signal replication distributing box.
The utility model solves above-mentioned technical problem through following technical proposals: a kind of signal replication distributing box, and said distributing box comprises shell, lower casing; Last pcb board and following pcb board, the row's of being fixed with pin on the last pcb board is fixed with said row female to the row who answers on the following pcb board; Be fixed with single one on the last pcb board and connect the Coaxial interface; Also be fixed with single one on the following pcb board and connect the Coaxial interface, all be fixed with scsi interface on last pcb board and the following pcb board, leave the hole that scsi interface and Coaxial interface are installed on the last shell; Last shell passes through screw together between last pcb board, following pcb board and the lower casing.
In the practical implementation example of the utility model, said row's pin has two groups with the row mother.
In the practical implementation example of the utility model, said going up on pcb board and the following pcb board has two scsi interfaces respectively.
In the practical implementation example of the utility model, two scsi interfaces are distributed in the left and right sides of Coaxial interface.
The positive progressive effect of the utility model is: the signal replication distributing box that the utility model provides has the following advantages: the utility model connects Coaxial alternative original double two with single one and connects Coaxial; Realize the transmission of coaxial cable signal through two PCB; Signal between two PCB connects to come transmission signals through connector; Realized and double two Coaxial of the company identical functions of use, practiced thrift great amount of cost simultaneously.
