Filed: 1990-02-20
Abstract: PURPOSE: To provide an easily assembling electric connector by applying compressing force and tensile force alternately to a terminal arranged in an insulating housing by means of a deflection locking lever extending forward and a deflection locking lever extending backward. CONSTITUTION: When a terminal 34 is inserted into a terminal recess 52 in an insulating housing 20, locking fingers 56, 62 are arranged in line with locking holes 96, 97 in the terminal 34. Deflection locking levers 54, 60 are returned in the bias prevention condition, while the forward faces of the fingers 56, 62 are firmly engaged in the hole 96, 97, so that the terminal 34 is prevented from being pulled out backward from the insulating housing 20. If backward force works on a lead wire 28 and the terminal 34, the locking lever 54 is compressed by means of the backward force, and at the sane time, the locking lever 60 is pulled. As a result of the composite reaction force of the compression force and the tensile force, the element is not destroyed or pulled out backward unless an extremely high backward force is applied.

IPC: C03C25/10
Filed: 1988-02-23
Abstract: PURPOSE:To suppress generation of a gap between a fiber and a buffer layer and to prevent degradation in the Young's modulus of a protective layer by maintaining the swelling weight of a resin which forms the buffer layer within 5% when the resin for forming the protective layer is immersed into the resin for forming the buffer layer prior to curing.
