Typical coaxial patchcord assemblies and plug boards are exemplified in U.S. Pat. Nos. 3,284,755, 3,341,801, and 3,335,388. These systems are designed for making board to board interconnections with a front board being preprogrammed with coaxial patchcords point-to-point. The front board is then plugged into a rear board with all of the preprogrammed patchcords being simultaneously interconnected with the boards. The coaxial patchcords are individually provided with very carefully machined connector elements. A typical connnector element, shown in U.S. Pat. No. 3,284,755, includes a smooth noise pin portion connected to the coaxial cable center conductor. The pin is encircled by a sleeve of dielectric material, which, in turn, is encircled by a conducting sleeve, also smooth and having resilient spring properties to allow retention in a corresponding aperture of a front board. Such a connector element is expensive to manufacture and assemble onto a coaxial cable. There has been a long existing need for an economical coaxial connector for point-to-point use without having to resort to patchcord connector elements.
