Claims

1. An electrical cable assembly comprising: multiple conductors of an electrical cable connected to circuitry on a circuit board, multiple electrical contacts in registration with respective conductive pads of the circuitry, an insulating holder holding the circuit board and the electrical contacts, an insulating housing receiving therein the holder and the electrical contacts and the circuit board, a window providing an open side of the housing, the contacts and the pads being exposed through the open side for inspection of the registration of the contacts with the pads.

2. An electrical cable assembly as recited in claim 1, and further comprising: a conductive shield encircling the housing and covering the window.

3. An electrical cable assembly as recited in claim 2 wherein, a strain relief on the shield grips the cable.

4. An electrical cable assembly as recited in claim 1, and further comprising: another window providing a second open side of the housing, the cable conductors and the circuitry being exposed through the second open side for inspection of connections of the cable conductors with the circuitry.

5. An electrical cable assembly as recited in claim 4, and further comprising: a conductive shield encircling the housing and covering both the window and said another window.

6. An electrical cable assembly as recited in claim 5 wherein, a strain relief on the shield grips the cable.
