Abstract: An electrical connector assembly including a first electrical connector and a second electrical connector connected therein in an electrical engagement. Each of the first and second electrical connectors including outer protective housings which are tapered from the connecting point between the first and second electrical connectors to opposite ends of each of the electrical connectors. Each of the protective housings includes internal bores in which is seated an electrical unit supporting electrical terminals and associated contacts in wires connected thereto. The wires extend from the electrical units through openings at opposite ends of the first and second electrical connectors. A threaded sleeve is threadably engagable with outer threads of the first and second connectors such that the first and second connectors are rigidly secured to each other.
