Abstract
The utility model discloses a novel bread board comprising a bread board and a power supply module, wherein the bread board comprises at least one power jack line connected with an "anode" of the power supply module, and at least one power jack line connected with a "ground" of the power supply module, the power supply module further comprises a "cathode", and at least one element jack is connected with the "cathode" of the power supply module. According to the bread board, the element jack line is directly connected with the "anode" of the power supply, and the element jack line is directly connected with the "ground" of the power supply, so that a large number of wire jumpers are free of use during experiments, and experiment efficiency is relatively high.
Description
Technical field
The utility model belongs to the Experiment of Electronic Technology technical field, is specifically related to a kind of bread board.
Background technology
Bread board is that the welding experimental design that aims at electronic circuit is made.Because various electronic devices and components can arbitrarily insert or extract as required, removed welding from, saved the built-up time of circuit, and element can reuse, so be fit to very much assembling, debugging and the training of electronic circuit.But there is following defective in existing bread board: bread board all is to connect power supply by wire jumper, thus when experiment on the whole bread board wire jumper very many very random.
Summary of the invention
The purpose of this utility model is to provide a kind of novel bread board, and this bread board is with the capable positive pole that directly connects power supply of element jack, and with the capable power supply ground that directly connects of element jack, so needn't use a large amount of wire jumpers when testing, conventional efficient is higher.
In order to realize above purpose, the technical scheme that the utility model adopts is: a kind of novel bread board is characterized in that: comprise bread board and power module; Described bread board has " positive pole " of 1 the capable connection of supply hub power module at least; Have at least the capable connection of 1 supply hub power module " ".
More excellent technical scheme, power module also comprise " negative pole "; Have at least 1 element jack to connect " negative pole " of power module.
More excellent technical scheme, power module output+5V and 12V; + 5V terminal be connected the 12V terminal and connect two input ends of the first change-over switch, the output terminal of the first change-over switch provides power supply for bread board.Owing to can export+5V can export again+so 12V namely can carry out digital circuit experiment, can carry out analogous circuit experiment again.
More excellent technical scheme, the output terminal of described the first change-over switch connects an end of fuse, and the other end of fuse provides power supply for bread board; The other end of fuse connects the input end of the second change-over switch simultaneously, and two output terminals of the second change-over switch are all by light emitting diode and current-limiting resistance ground connection.Better Protection element of fuse has been arranged, and light emitting diode can indicate that experiment time uses be+the 5V power supply or+the 12V power supply.
Write for this patent and to express clearly succinctly, carry out giving a definition: bread board generally connects per 5 orifice plates with a strip metal bar, is defined as the element jack for the jack of the component tests such as integrated circuit, chip; Be used for providing the jack of power supply to be defined as supply hub to the element on the plank; It is capable that the row at supply hub place is defined as supply hub.
Compared with prior art, the utility model has the advantage of: this bread board directly connects power supply ground with the capable positive pole that directly connects power supply of supply hub with the element jack, so needn't use a large amount of wire jumpers when testing, conventional efficient is higher.And use better Protection element of fuse, use change-over switch conveniently to provide multiple power sources voltage as bread board.

Fig. 1 is existing bread board structural representation;
Fig. 2 is the structural representation of a specific embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Novel bread board comprises bread board and power module; Power module output+5V and 12V; + 5V terminal be connected the 12V terminal and connect two input ends of the first change-over switch, the output terminal of the first change-over switch connects an end of fuse, the other end of fuse provides power supply for bread board; The other end of fuse connects the input end of the second change-over switch simultaneously, and two output terminals of the second change-over switch are all by light emitting diode and current-limiting resistance ground connection.Better Protection element of fuse has been arranged, and light emitting diode can indicate that experiment time uses be+the 5V power supply or+the 12V power supply.Described bread board has " positive pole " of 1 the capable connection of supply hub power module; Have the capable connection of 1 supply hub power module " ".
