ABSTRACT:
The interlock device for a connector (e.g. a fusible link connector)--junction block assembly includes a first lock mechanism for locking the insulating housing of the connector in position, against downward displacement, within the mounting framework of the junction block, and a second mechanism for locking the insulating housing in the same position, against upward displacement, within the mounting framework of the junction block substantially simultaneously with the first lock mechanism. The first and second lock mechanisms respectively each include a pair or pairs of wedge-shaped lock pawls with one provided on the insulating housing and the other on the mounting framework. Mating pawls, respectively, have slidable contact surfaces with oppositely directed gradients and oppositely facing lock surfaces. The device, further, has a first resilient release lever for releasing the first lock mechanism when desired to pull the connector downwardly and a second resilient release lever for releasing the second lock mechanism when desired to pull the connector upwardly for maintenance or servicing of the connector. Replacement or inspection of the inner components of the connector, therefore, can be effected quickly conveniently simply by opening the top cover of the junction block.
