Abstract
The utility model discloses a welding-free type universal circuit board (shortened as a bread board as follows). The bread board comprises a panel and a soleplate fixed under the panel. The combination and the assembly of the bread board are very convenient and the bread board can be assembled at will according to the actual requirement. The bread board is arranged by adopting a double layer structure, when a connecting line breaks in the bread board, bolts at the back are disconnected, a plastic soleplate is demounted, and an elastic piece is taken out, thus, a broken line can be cleared up easily, after being assembled again, the bread board can be reused, assembled parts inside the bread board also have complete interchangeability. Celloidin at the back of the prior bread board is canceled, thereby ensuring that the bread board is more wearable, and greatly prolonging the service life of the bread board. The size of the bread board can be jogged and assembled according to the actual requirement, thereby being convenient and applicable. The utility model has an elegant appearance.
Description
Technical field
The utility model relates to a kind of circuit board, particularly a kind of bread board (welding-free type general-purpose circuit board).
Background technology
All stick insulating cement when existing bread board uses, and then the bread board that quantity is not waited is stitched together, again its stickup or screw is fixed on the big plate of a slice at the plastic housing back side that bread board is inserted good shell fragment.
In use there is following drawback in above-mentioned bread board:
Can not be according to actual needs the bread board that is suitable for of combined size at any time, even only the experiment that needs small pieces to finish also has to use large stretch of bread board, cause the waste in material and space;
Used foam glue in the bread board back side or individual layer gummed paper used and can occur the viscosity inefficacy for a long time, and it is insecure to fit, the repeated use of influence surface wrapper sheet;
Bread board in use is easy to occur broken string in the bread plate hole, because its back side is sealed by glue, so can not keep in repair, causes the effective usable floor area of piece of bread plate more and more littler, has a strong impact on the useful life of bread board.
Summary of the invention
The purpose of this utility model provides a kind of convenient maintenance, and the bread board of long service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bread board, this bread board include panel and are fixed on the base plate of this panel below.
Wherein, the side of this base plate and/or this panel is provided with the dovetail projection and the dovetail groove of one or more mutual engaging.
Wherein, this panel and base plate by screw be arranged on panel and be connected with screw on the base plate.
Positive progressive effect of the present utility model is:
A kind of bread board owing to be provided with dovetail projection and the dovetail groove that mutual card is established, makes that its composite assembly is very convenient, assembling arbitrarily according to actual needs; Bread board adopts the double-decker setting, breaks in the bread plate hole when connecting line occurring, takes the back screw apart and unloads plastic bottom board, take out shell fragment, can easily clean out broken string, re-assembly again, can reuse again, its inner parts also has absolute interchangeability; Cancelled the back side foam glue of existing bread board, allowed the bread board can be durable in use, greatly elongated surfaces wrapper sheet useful life; Good looking appearance is generous.
