Description

A kind of DSub-Bnc wire jumper signal box

Technical field

The utility model relates to signal transmission technology field, particularly a kind of DSub-Bnc wire jumper signal box.

Background technology

Along with science and technology is maked rapid progress, the equipment of all size purposes emerges one after another, is applied to different social sectors, various kinds of equipment be built into integrated system work in coordination with use occasion get more and more; Various equipment, often lacks unified interface and standard, uses and bother very much; For psychological study equipment, be equipped with between the computer of E-Prime program and various external equipment and there is interface problem, different input equipment collect reaction time there are differences problem, multiple distinct device cannot be driven simultaneously, the connection of each peripheral hardware and synchronous Trigger Problems cannot be solved.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of compatible connection signal box for different size equipment interface, makes compatibility easy to useization of different size, multiple equipment use synchronization.

For solving the problems of the technologies described above, the utility model provides a kind of DSub-Bnc wire jumper signal box, comprising: D-Sub interface, Bnc interface array and handing-over casing;

Described D-Sub interface is connected with described Bnc interface array by wire jumper, and fixing by described handing-over casing encapsulation;

Wherein, 2nd ~ 15 pins of described D-Sub interface, adopt connected mode one to one, in turn D0 ~ D7, IM, I1, PM, I2 ~ I4BNC signal core line of corresponding described Bnc interface array; The ground wire of described Bnc interface array is connected with the 25th pin of described D-Sub interface.

Further, ventilation by forced draft louvre offered by described handing-over casing.

Further, described handing-over top cover of box is removable top.

Further, one-to-two interface or one point of multiplex roles is also comprised;

2nd ~ 15 pins of described D-Sub interface connect the input of described one-to-two interface or one point of multiplex roles, and the output of described one-to-two interface or one point of multiplex roles connects described Bnc interface array.

The DSub-Bnc wire jumper signal box that the utility model provides is by adopting conventional D-Sub interface and Bnc interface as medium, realize the variation of connecting interface, to adapt to the equipment connection user demand of multi-form specification, greatly reduce the connection complexity that device systemsization uses; On the other hand, also can connect more equipment, realize the synchronization that signal triggers simultaneously, greatly improve the efficiency that systematization uses.

Embodiment

See Fig. 1 ~ 3, a kind of DSub-Bnc wire jumper signal box that the utility model embodiment provides, comprising: D-Sub interface 4, Bnc interface 2 array and handing-over casing 1;

D-Sub interface 4 is connected with Bnc interface array 2 by wire jumper, and encapsulates fixing by handing-over casing 1;

Wherein, 2nd ~ 15 pins of D-Sub interface 4, adopt connected mode one to one, in turn D0 ~ D7, IM, I1, PM, I2 ~ I4BNC signal core line of corresponding Bnc interface array 2; The ground wire of Bnc interface is connected with the 25th pin of D-Sub interface.

Ventilation by forced draft louvre 3 offered by handing-over casing 1.

Handing-over casing 1 top cover is removable top, is convenient to safeguard.

Can the quantity of compatible equipment in order to increase, preferably, also comprise one-to-two interface or one point of multiplex roles;

2nd ~ 15 pins of D-Sub interface 4 connect the input of one-to-two interface or one point of multiplex roles, and the output of one-to-two interface or one point of multiplex roles connects Bnc interface array; Thus increase the Bnc interface quantity of Bnc interface array, and then realize dilatation.

See Fig. 4, the present embodiment illustrates connected mode for psychological study system, and computer, stimulation are presented system and be connected with multiple peripheral hardware by this " DSub-Bnc wire jumper signal box ", present system for prior art moderate stimulation and can only connect single peripheral hardware, the deficiency that simultaneously can not connect multiple peripheral hardware develops, current computer is connected with various peripheral hardware by parallel port, and electroencephalograph, eye tracker, FMRI system, transcranial magnetic stimulation instrument, near-infrared spectroscopy instrument etc. is connected with peripheral hardware by Bnc interface, the utility model well solves this problem, 25 pin parallel port input signals, after " DSub-Bnc wire jumper signal box ", be converted to multichannel Bnc signal to export, realize the convenient connection of system, effective use.

It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to example, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
