Abstract
A jumper providing electrical communication between two components of a producing well of an oil field. The jumper has two tubings for insertion in two components each with an anchor adapted to be rigidly mounted in its associated component. Each tubing has a centering device, consisting of a pair of rings surrounding the tubing and an array of bowed springs bridging between the rings and biased to bow outwardly into engagement with the bore of the associated component. One of the two rings is electrically and mechanically connected to the tubing, whereas the other ring is free to be displaced longitudinally of the tubing so that the outer diameter of the array of bowed el springs may expand or contract, as needed. Each bowed spring in the array is provided with supplemental electrical contacts to insure a path of electrical conductivity between the connected ring and the associated component through the bowed springs.
