The connections on a PCB should be identical to its corresponding circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation.

I am currently routing a 4 layers PCB and thinking how to connect the ground and power planes to the connector and components that need them.

You can use a via to connect from the signal planes to the internal power or ground plane.

A via can help to connect to a ground plane. In case of surface-mount component, there is separate via connected to the surface-mount pad. In case of throughole component, the pin is soldered into the via.

As someone answered for thru-hole components, I want to answer for SMD components. Connect the ground or power leads to short traces. A via placed on those traces should automatically connect to the appropriate plane.

For thru-hole components, pins connected to the Vcc or GND nets will be automatically connected to the power or ground planes as needed.

If you put a big copper plane for ground on layer 2 and another one for power on 3 and assign them to the ground and power nets. PADS will automatically connect them when you flood the copper.
