Integral terminal compartment with deployable terminal block
A terminal compartment for installation in the hand hole of a utility pole. The compartment comprises a frame, such as an oval weldment ring with a cover. A terminal block support is movably mounted in the compartment for movement between an operating position and a deployed position. In the operating position, a terminal block fixed to the terminal block support is contained entirely inside the internal space of the utility pole. In the deployed position, the terminal block extends through the access opening at least partially outside the pole. The terminal block support may be an elongate rigid strip mounted vertically inside the compartment with a bottom end hingedly attached to the frame. In this way, once the cover is removed, the terminal block can be folded down to a horizontal position extending out through the access opening and affording easy access for repair and maintenance.
1. A terminal compartment for supporting a terminal block inside an internal space of a utility pole, the utility pole having a hand hole for accessing the internal space, the compartment comprising:
a frame mountable in the hand hole of the utility pole and defining an access opening and an enclosure; and
a terminal block support movably mounted in the enclosure of the frame for movement between an operating position and a deployed position, wherein in the operating position a terminal block fixed to the terminal block support is contained entirely inside the internal space of the utility pole, and wherein in the deployed position a terminal block fixed to the terminal block support will extend through the access opening at least partially outside the pole.
2. The terminal compartment of claim 1 wherein the frame comprises an oval sidewall.
3. The terminal compartment of claim 1 further comprising a removable cover sized to cover the access opening.
4. The terminal compartment of claim 1 wherein the terminal block support comprises an elongate rigid strip.
5. The terminal compartment of claim 4 wherein the rigid strip has a first end and a second end, wherein the first end is pivotally attached to the frame.
6. The terminal compartment of claim 5 wherein the rigid strip pivots about an axis that is normal to the longitudinal axis of the utility pole.
7. The terminal compartment of claim 6 wherein in the deployed position the rigid strip is vertically positioned with the first end of the rigid strip below the second end and so that in the deployed position the second end of the rigid strip is outside the access opening.
8. A terminal block assembly comprising the terminal compartment of claim 1 and a terminal block secured to the terminal block support.
9. A utility pole assembly comprising a utility pole and a terminal block assembly as defined in claim 8 installed in the hand hole.
10. A traffic control assembly comprising the utility pole assembly of claim 9 and traffic control device mounted on the utility pole.
