<p>The electrical connector has a coupling nut provided with ratchet teeth on one end for cooperating with a spring, so that the coupling nut is harder to rotate in one direction than the other. The spring is formed as a leaf spring, having an elongate arm which cooperates with the forward and rearward faces of the ratchet teeth extending from the coupling nut. The relation between the leaf spring and the ratchet teeth is such that any compressive force acting on the spring during turning of the coupling nut is relatively light, and so the spring does not buckle as the coupling nut is turned.</p> |
