Description
Technical field
The utility model is related to a kind of circuit boards, are specifically a kind of three layers of terminal board.
Background technology
The outside drawing of existing product as shown in figure 3, line map as shown in figure 4, it only has access the signal wire of load signal,
Two power cords ("+", "-") of load signal (such as sensor) must guide to other wire connection terminal wiring, so need to increase end
Sub (cost increase), occupies the more spaces of power control cabinet, and circuit cabling unsightly, increases the degree of difficulty fixed a breakdown.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of three layers of terminal board, to solve what is mentioned in background technology
Problem.
To achieve the above object, the utility model provides following technical solution：
A kind of three layers of terminal board, including shell and circuit board, the circuit board is installed inside the housing, the top of circuit board
Equipped with connector, the middle part of circuit board is equipped with signal terminal, and the bottom of circuit board is equipped with power supply terminal, the outer side of the shell
Side central symmetry position is set there are two screw installation card base, and the bottom outside of shell is equipped with guide rail and installs card base.
Further technical solution as the utility model：The connector is 40 connectors.
Compared with prior art, the beneficial effects of the utility model are：The utility model is in the identical size of existing product
Under, increase loaded power supply terminal (newly devising terminal die), reduce the occupied space of power control cabinet, circuit cabling
Beauty reduces the degree of difficulty fixed a breakdown.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the line map of the utility model.
Fig. 3 is the structure chart of the prior art.
Fig. 4 is the line map of the prior art.
In figure：1- shells, 2=wiring boards, 3- connectors, 4- signal terminals, 5- power supply terminals, 6- screws installation card base,
7- guide rails install card base.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, a kind of three layers of terminal board, including shell and circuit board, the circuit board is installed inside the housing,
The top of circuit board is equipped with connector, and the middle part of circuit board is equipped with signal terminal, and the bottom of circuit board is equipped with power supply terminal, described
The external side central symmetry position of shell is set there are two screw installation card base, and the bottom outside of shell is equipped with guide rail installation card
Foot.
Connector is 40 connectors.
The operation principle of the utility model is：The design improves in board design and on connection function, increases
The circuit and power supply terminal of loading signal, the power cord so loaded can be directly connected to terminal platform, need not guide to
Other terminals, specific implementation:Tri- lines of signal, 24V, 0V of load can connect the signal terminal of terminal platform, "+" end respectively
Son, "-" terminal can very easily find wired, the reduction investigation failure of corresponding load when load is faulty
Time and degree of difficulty.
