Abstract
The utility model relates to a data bus switching device, in particular to a switching device from a 1394 interface to a multi-core aerial plug. The structure of the utility model comprises IEEE-1394 mail plugs respectively welded on the both sides of a multi-layer printed board and a multi-core aerial plug, and the core wires of the both plugs are connected one-to-one through a printed board connecting line. The data bus switching device can successfully solve the problems that when the original switching device transmits the 1394 signal, the transmission distance is short, the reliability is poor, the mechanical stability is poor, etc., the 1394 signal line can transmit repeatedly between the main controlling computer and the testing device, and the reliability and the stability of the transmitted signal can not be influenced.
Description
Technical field
The utility model relates to a kind of data/address bus switching device, is specially the conversion equipment of a kind of 1394 interfaces to the multicore aviation plug.
Background technology
In 1394 bus Auto-Test Systems, need between main control computer and the testing equipment to carry out high speed data transfer by 1394 buses.In some test macros, be subjected to the restriction of factors such as distance, structure, space, interface, can't directly be connected to testing equipment with one 1394 cable by main control computer, intermediate demand is transferred to 1394 cables or is prolonged.The conversion equipment of using in the past all is to be transformed into 1394 male contacts from 1394 male contacts, and main control computer one end is installed a conversion equipment, and testing equipment one end is installed a conversion equipment, links to each other with cable respectively; Main control computer and testing equipment couple together the most at last with one 1394 cable again between two conversion equipments.Because 1394 male contacts are difficult to fix, shield difficulty and link shortcomings such as unreliable to the conversion equipment existence of 1394 male contacts, be easy to be disturbed by outer signals, cause problems such as the signal transmission reliability is low, mechanical stability difference, be difficult to long-time reliable the use.
Summary of the invention
The purpose of this utility model is to connect the existing defective of conversion equipment at existing 1394 cables, and the conversion equipment of a kind of 1394 interfaces of the reliability and stability that improve the signal transmission to the multicore aviation plug is provided.
The technical solution of the utility model is as follows: a kind of 1394 interfaces are to the conversion equipment of multicore aviation plug, comprise the IEEE-1394 convex plug and the multicore aviation plug that are welded on the multilayer printed board both sides respectively, link to each other one to one by the heart yearn of printed board line with two plugs.
Aforesaid a kind of 1394 interfaces are to the conversion equipment of multicore aviation plug, wherein, described printed board has 4 conductive layers, and top layer and bottom are ground plane, middle two-layer be routing layer, the shell of two patchplugs welds together with the front and back ground plane of printed board respectively.
Aforesaid a kind of 1394 interfaces wherein, are equated by 1394 male contacts each wire length to the multicore aviation plug to the conversion equipment of multicore aviation plug.
The utility model changes 1394 male contacts in the former conversion equipment conversion regime of 1394 male contacts to the multicore aviation plug into to the conversion regime of 1394 male contacts, and multicore aviation plug end is used for two connections between the conversion equipment.Because aviation plug has plurality of advantages such as connecting reliable, convenient fixing and advantages of good shielding performance, has overcome the shortcoming that former technical scheme exists, and makes the long Distance Transmission of 1394 holding wires and switching transmit all very reliable.

Fig. 3 is a side structure schematic diagram of the present utility model.
Among the figure, 1. multicore aviation plug 2. printed board 3.IEEE-1394 convex plugs
Embodiment
As shown in the figure, the utility model comprises multicore aviation plug 1, multilayer printed board 2, IEEE-1394 convex plug 3, and IEEE-1394 convex plug 3 and multicore aviation plug 1 are welded on the both sides of printed board 2, and is continuous one to one by the heart yearn of two plugs of printed board line.Printed board has 4 conductive layers, top layer and bottom are defined as ground plane, and the middle two-layer routing layer that is defined as is for guaranteeing the globality of signal wire transmits, the shell of two patchplugs welds together with the front and back ground plane of printed board respectively, guarantees to contact well with ground shield.All keep strict conformance by the IEEE-1394 male contact to the wire length of multicore aviation plug, the signal transmission is kept synchronously.Aviation plug carries ring flange, has 4 to install and fix the hole on the ring flange, is used for and the fixedlying connected of other structure.This conversion equipment has dependable performance, advantage easy for installation.
The utility model can successfully solve former conversion equipment when transmitting 1394 signals, problems such as transmission range weak point, poor reliability and mechanical stability difference, make 1394 holding wires can be between main control computer and testing equipment, and do not influence the reliability and stability of its signal transmission through repeatedly switching.
