Description
Technical Field
The utility model belongs to the technical field of circuit board line connection, concretely relates to pencil is to circuit board wiring structure.
Background
In the prior art, the circuit board of the electronic product is usually a single-sided device plug-in for cost saving. The board card side will typically be uneven and only the surface of the chip device will be flat. When the circuit board is mounted to the housing, the flat surface is generally oriented downward toward the housing and the insert is oriented upward.
The cable is connected with the circuit board, and the common practice in the prior art is to weld a terminal with a nut on the plug-in surface of the circuit board and press-fit a through hole terminal on the wiring harness. The wire harness terminals are locked with the terminals on the circuit board by screws. This approach is more suitable when there are fewer wire harnesses and the connection point is at the edge of the circuit board.
However, when the connection point is located at the middle of the circuit board, the wiring harness needs to be avoided from the plug-in device on the circuit board, which may cause the wiring harness to be lengthened and bent, and may cause poor EMC environment. The larger the number of wire harnesses, the more difficult it is to route the circuit board in the middle.
Disclosure of Invention
In order to solve the problem, the utility model provides a pencil is to circuit board wiring structure can carry out pencil location and fixed bottom the circuit board to realize reducing pencil length, improve the effectual utilization of circuit board bottom space, and avoid flying the line above circuit board plug-in components, reduce the EMC interference of irregular wiring.
The technical scheme of the utility model as follows:
the utility model provides a pencil is to circuit board wiring structure, includes the casing, the pencil fixing base is installed to the casing bottom, the pencil fixing base includes a plurality of fixed cassettes and connects the connecting plate of fixed cassette, be fixed with the pencil on the fixed cassette, the connecting plate top is connected through inserts bolt and nut and is fixed with the circuit board.
Preferably, the wire harness fixing seat is further provided with a crimping terminal, the wire harness is inserted into a cavity of the crimping terminal, and is positioned and locked to the wire harness fixing seat through the wire pressing terminal, the insert bolt and the nut.
Preferably, the bottom of the shell is further provided with a positioning column, and the positioning column fixes the wire harness fixing seat to the bottom of the shell through positioning holes formed in two ends of the wire harness fixing seat.
Preferably, the wire harness fixing seat is further provided with a buckle for preliminarily fixing the wire harness.
Preferably, the plane of the contact between the crimping terminal and the circuit board is higher than the plane of the buckle of the wire harness fixing seat, so as to ensure good contact between the crimping terminal and the circuit board.
The technical effects of the utility model are that:
the utility model discloses can let the pencil not receive the interference of plug-in components device, reduce the crooked and the length of pencil, reduce the irregularity degree of wiring.
And the wiring can be simply and neatly arranged, the possibility of EMC interference caused by the wiring harness is reduced, and the internal space is saved.
And a shorter wiring harness is adopted, so that the EMC interference possibility is lower, the space occupation ratio is smaller, and the cost control is facilitated.
