Description
Technical field
This utility model belongs to pcb board field, particularly relates to the fixed structure of electric current transmission between a kind of pcb board.
Background technology
To transmit big electric current between pcb board part and pcb board part, and require fixing between plate and plate, by space
Limit, the place that a lot of inconvenient operation and installation are safeguarded can be there is, as connected with wire, then wiring to be installed at wire two ends
Nose, if transmission electric current is relatively big, also needs heavy gauge wire to connect, can exist in the case of space is little much be inconvenient to operate with
The place safeguarded is installed；At fixing aspect, connect, with wire, fixing effect of then can not playing, also need to increase the fixed bit in other places
Put, design more difficult.
First being fixed on by conduction column on pcb board part, other pcb board can be installed the most again, can use conduction column
Or it is screwed；Can also be welded on pcb board part one end of conduction column, the other end is screwed, conduction column
Height can be adjusted by the element height between pcb board part；Be usually found between two pieces or polylith pcb board part to transmit big
Electric current also requires fixing simultaneously, there is area and not but requires to transmit the practical situation of big electric current, the ability of conductor propagation electric current
It is directly proportional to cross-sectional area of conductor area, thus adds design difficulty, affect work efficiency.
Summary of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, between this utility model a kind of pcb board of offer, electric current transmission consolidates
Fixed structure, this fixed structure can be fixed polylith pcb board, can transmit again electric current between polylith pcb board, not affect PCB simultaneously
The design space of plate.
For achieving the above object, this utility model adopts the following technical scheme that the fixed knot of electric current transmission between a kind of pcb board
Structure, including pcb board body, conduction column, described pcb board body at least provided with two-layer, is provided with consolidating of matching between adjacent pcb board
Determining hole, described pcb board body is provided with the circuit line being connected with fixing hole, and described conduction column is that the bilateral that conducting medium is made is led
Through post or single-pass conduction column, described bilateral conduction column two ends are provided with female thread, and described single-pass conduction column one end is provided with female thread, and one
End is provided with and the external screw thread of bilateral conduction column screw-internal thread fit, and conduction column is connected at fixing hole, and bilateral conduction column passes through screw
Or single-pass conduction column fixes, single-pass conduction column is fixed by single-pass conduction column or screw.
In technique scheme, described fixing hole and conduction column are circular or polygonized structure.
The beneficial effects of the utility model are: electrically connected with the circuit on pcb board by conduction column, save another external wire
Space, thus add the design space between pcb board；Direct conduction column is fixed, it is not necessary to additionally perforate on pcb board,
Decrease the fixed hole position between pcb board；The electric current that can conduct according to actual needs, selects the conduction column of different specifications,
Adapt to the big electric current transmission between two pieces or polylith pcb board.

Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
The fixed structure of electric current transmission between a kind of pcb board, the first pcb board 1, the second pcb board 2, the 3rd pcb board 3, described
Pcb board body is provided with the circuit line being connected with fixing hole, and described conduction column is the bilateral conduction column 4 made of conducting medium and single
Admittance through post 5, described bilateral conduction column 4 two ends are provided with female thread, and described single-pass conduction column 5 one end is provided with female thread, and one end sets
Having and the external screw thread of bilateral conduction column screw-internal thread fit, conduction column is connected at fixing hole, bilateral conduction column 4 by screw 6 or
Single-pass conduction column 5 is fixed, and single-pass conduction column 5 is fixed by single-pass conduction column 5 or screw 6, is additionally provided with between screw 6 and pcb board
Spring washer 7, plain cushion 8.
In the above-described embodiments, can regulate according to actual needs conduction column number and with the connection position of pcb board body
Put.
In technique scheme, described fixing hole and conduction column are circular or polygonized structure.The above, be only
This utility model preferably detailed description of the invention, but protection domain of the present utility model is not limited thereto, any is familiar with this skill
The technical staff in art field in the technical scope that this utility model discloses, the change that can readily occur in or replacement, all should contain
