Patent attributes
A terminal block includes an insulative casing, a bottom plate, conductive terminals and a light module. The insulative casing has first chambers, second chambers and through holes separately communicating with the first chambers. The bottom plate coves the first chambers. A side of the bottom plate and the second chambers are formed with a circuit board slot. The bottom plate is extended with light guide bars separately passing through and exposed in the through holes. The conductive terminals are separately received in the first chambers. Each conductive terminal is extended with a contact sheet disposed in the second chamber. The light module includes a circuit board, LEDs mounted on the circuit board and conductive units. When the circuit board is detachably inserted into the circuit board slot, the LEDs correspond to the light guide bars in position, and each conductive unit electrically connects to one of the contact sheets.
