A spike and socket cable termination assembly includes an outer socket having a substantially conical bore disposed therethrough with the bore having a smaller first open end and a larger second open end. The socket is constructed of a first material. A cable has an end portion thereof received through the smaller first open end of the substantially conical bore. A spike having a substantially conical outer surface is received through the larger second open end of the conical bore and in a center portion of the cable end portion with strands of the cable distributed in a substantially conical shape between the spike and socket. The spike is tightly wedged in the socket so that strands of the cable are held in place between the spike and socket. The spike is constructed of a second material having a modulus of elasticity substantially greater than the modulus of elasticity of the first material from which the socket is constructed. This substantially reduces transverse normal compressive stresses applied to the strands of the cable end portion thus increasing a cyclical load life of the cable as compared to a similar spike and socket having the socket modulus of elasticity at least as great as the spike modulus of elasticity. |
