4. The PCB board of claim 1, further comprising a screw and a screw hole, wherein the PCB board (1) and the function expansion module (2) are detachably fixed by the screw and the screw hole.

5. The PCB of claim 4, wherein the screw hole is provided on the PCB (1), and the screw is provided on the function expansion module (2).

6. The PCB board of claim 1, further comprising a hole and a threaded rod, wherein the PCB board (1) and the function expansion module (2) are detachably fixed by the hole and the threaded rod.

7. A PCB board according to claim 6, characterized in that the holes in the function expansion module (2) are in threaded connection with threaded rods arranged in the holes.

Technical Field

The invention relates to the technical field of circuit boards, in particular to a PCB.

Background

When the main PCB is designed in the early stage, all functions of the lamp need to be simulated, and finally, corresponding interfaces need to be added, and the functions of the main PCB are fixed and difficult to change unless the PCB is re-designed, so that products on the hands of customers cannot be upgraded quickly.

When a customer needs to upgrade a product on hand suddenly, many parts need to be replaced, and the steps are complex, so that a PCB is provided for preventing compatibility of function upgrading of the product and adding more practical functions to the product through the expanded function board.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a PCB, which solves the problems that when a client needs to suddenly upgrade the function of a product on hand, a plurality of parts need to be replaced, and the steps are complicated.

The invention provides the following technical scheme: a PCB board comprising: the PCB board and the function expansion module are electrically connected through the detachable connection of the expansion interface and the expansion terminal.

Preferably, the expansion interface is in plug-in fit with the expansion terminal.

Preferably, the expansion interface is fixed on the PCB, and the expansion terminal is fixed on the function expansion module.

Preferably, the PCB further comprises a screw and a screw hole, and the PCB and the function expansion module are detachably fixed through the screw and the screw hole

Preferably, the screw hole is arranged on the PCB, and the screw is arranged on the function expansion module.

Preferably, the PCB further comprises a hole and a threaded rod, and the PCB and the function expansion module are detachably fixed through the hole and the threaded rod.

Preferably, the hole on the function expansion module is in threaded connection with a threaded rod arranged in the hole.

Compared with the prior art, the invention has the following beneficial effects:

before no additional function modularization, when a main PCB is designed, all functions of a lamp need to be simulated, and finally a corresponding interface needs to be added, and the functions of the main PCB are fixed and difficult to change unless the main PCB is replaced.
