Electrical connector housing assembly and electrical connector

Abstract

The present application discloses an electrical connector housing assembly and an electrical connector. The electrical connector housing assembly comprises a housing provided with several plug-fitting holes for arranging plug-fitted terminals; and a rear-end cap detachably mounted at a rear end of the housing and covering part of the plug-fitting holes. The electrical connector comprises an electrical connector housing assembly and a plurality of inserted plug-fitted terminals. According to the electrical connector housing assembly of the present disclosure, by providing slots on hole walls among a row of plug-fitting holes wherein all slots forming a communicative elongated groove which may receive plug-fitted terminals of a wide-flat line body unbranched at a front end; by arranging the hole walls between plug-fitting holes to be thinned to receive plug-fitted terminals of a wide-flat line body branched at the front end; by plugging a plug-fitted terminal of a cylindrical line body structure into a single plug-fitting hole, the electrical connector housing assembly and the electrical connector of the present disclosure are enabled to be simultaneously adapted to three plug-fitted terminals of different line body structures.
