Abstract A modular plug has at least two rows of contact chambers lying next to one another in which spring contacts are located. The spring contacts are connected at one end to the conductors of a cable. The first and last spring chambers of each row are designed as empty chambers into which catch hooks can be introduced. These empty chambers are employed to accept strain relief inserts which are designed as L-shaped structures in which an elongate member of the L-shaped strain relief insert terminates in a catch hook to bear against the forward face of the plug and the cross member of the insert is designed as a tab which has passages therethrough which lie opposite similar passages of a second strain relief insert upon engagement of the elongate members in the empty chambers. The cable can thereby be introduced between the cross members and secured by the cable strap which extends through the passages. The material of the cross members outboard of the passages is designed with a break rating so that sections of the cross members may be broken off to reduce the lengths of the cross member.
For use with a modular plug of the type which has a forward surface and parallel rows of contact chambers extending rearwardly of said forward surface with contacts in at least some of the chambers as necessary except for diagonally opposite chambers of two separate rows, and which has a plurality of conductors of a cable connected to respective contacts, a strain relief for the cable comprising: a pair of L-shaped inserts each including an elongate member and a cross member, each of said elongate members including a hook at its distal end and sized to be received through an empty contact chamber so that said hook engages against said forward surface to latch and prevents rearward movement of said insert, and means defining spaced apertures through said cross member of each of said inserts so that when both inserts are latched in the respective empty contact chambers with the cross members extending in mutually opposite directions some of said apertures of both inserts are generally opposite one another on opposite sides of the cable; and a cable strap for extending through the opposed apertures to secure the cable.
