An insulting cover for industrial control components employs a cover support that may simply attached to existing or specially prepared structures on the control component, which supports a door that may be opened or closed for access to the control component. A variety of different covers may be simply generated using CAD templates executed to cut sheets of plastic that may be formed with relatively simple and low cost techniques.

Protective electrically insulating cover with access door

The invention relates to a conveyor having a first conveyor element including an end made of an interiorly located eye including therein an opening, and an end eye adjacently spaced from the interior eye to define therebetween a space and including therein an opening located in axial alignment with the opening in the interiorly located eye and having a given dimension, a second conveyor element including an end having an eye extending into the space between the end eye and the interiorly located eye and including therein an opening axially aligned with respect to the openings in the end eye and the interiorly located eye, and a hinge pin including a cylindrical portion extending in the opening in the interiorly located eye of the first conveyor element and in the opening in the eye of the second conveyor element, and an axially outwardly diverging conically shaped end portion extending axially from the cylindrical portion and including a diametrically and axially extending slot defining opposed barbs having outer ends located in adjacent relation to the end eye and having a dimension greater than the dimension of the opening in the end eye so as to normally be impassable through the opening in the end eye, whereby to normally prevent axially outward passage of the hinge pin through the end eye and whereby to permit passage of the hinge pin through the opening in the end eye when the barbs are displaced toward each other.
