Description

Technical Field

[0001] This utility model relates to a connector end cap, a connector housing assembly including the connector end cap, and a connector including the connector housing assembly. Background Technology

[0002] In existing technology, connectors typically include a housing and an end cap assembled to the rear end of the housing. The connector cable exits from the rear port of the end cap. Elastic clips and tongues are formed on the upper and lower parts of both sides of the end cap, respectively. The elastic clips on the upper part of the end cap are locked into a slot in the housing, and the tongues on the lower part of the end cap are inserted into a socket in the housing. When an operator manually grasps the cable exiting from the rear port of the end cap, the cable exerts a significant vertical force on the end cap. This force is transmitted to the elastic clips on the end cap, causing deformation and damage, and even leading to the elastic clips disengaging from the slots on the housing. Once the elastic clips disengage from the slots on the housing, the end cap also detaches from the housing. Utility Model Content
