Abstract: Disclosed herein is a pair of electrical connectors including a plug connector and a receptacle connector. The plug connector includes a plug housing, a plug signal terminal, a plug power terminal, and a fastening wall. The receptacle connector includes a receptacle housing, a receptacle signal terminal, a receptacle power terminal, and a fastening groove. With the plug connector completely fitted into the receptacle connector, the fastening wall is placed on the fastening groove.

Abstract: Disclosed herein is an electrical connector including a plug connector mounted on a substrate and connected to a receptacle connector. The plug connector includes: a plug housing including a base and first to fourth walls; and multiple plug signal terminals disposed at least on the first wall. A recess is formed between the plug signal terminals to be located below an upper end of the first wall of the plug housing. In the receptacle connector as a mating connector, a protrusion is formed between receptacle signal terminals 20-3 to be located above a base of a receptacle housing of the receptacle connector. The recess of the plug connector (10) receives the protrusion of the receptacle connector therein.

Abstract: Disclosed herein is an electrical connector (10) mounted on a substrate and connected to a mating connector (20). The electrical connector (10) includes: a housing including a base, a first wall (10-5-W1) protruding from an upper surface of the base and extending in a longitudinal direction of the electrical connector (10), and a second wall (10-5-W2) protruding from the upper surface of the base and facing the first wall (10-5-W1); multiple contacts (10-3) disposed on the first wall (10-5-W1) and the second wall (10-5-W2); and a shielding part (10-S) formed around a periphery of the housing (10-5). The shielding part (10-S) has a curved portion (10-S-C) formed at an upper end of a side surface thereof and curved inwards in a transverse direction (Y-axis direction) of the electrical connector (10) and an inclined portion (10-S-I) formed inside the curved portion (10-S-C) in the transverse direction of the electrical connector (10) and adjoining the curved portion (10-S-C).

Abstract: Disclosed herein is a type-C signal transmission connector. The type-C signal transmission connector includes: an inner housing receiving a USB plug and a cable therein; an outer housing surrounding the inner housing; and a retainer mounted on the inner housing and the outer housing, wherein the retainer has an outer locking portion and a protrusion, the outer locking portion is caught by a catching portion formed on the outer housing, and the protrusion is coupled to an inner protrusion receiving portion formed on the inner housing.

Abstract: A method of manufacturing an electrical connector coupled to a counterpart connector is disclosed. The method includes: (a) disposing a plurality of signal terminals; (b) forming a first mold part to support the signal terminals through primary insert molding, the first mold part being formed to have a protrusion at one end thereof in a longitudinal direction of the electrical connector and a first groove at the other end thereof in the longitudinal direction of the electrical connector; (c) placing a fitting beside the first mold part; and (d) forming a second mold part to support the first mold part and the fitting through secondary insert molding, the second mold part being formed to surround the protrusion of the first mold part while filling the first groove.

Abstract: A connector assembly includes: a plug connector including a mold support, a first terminal structure protruding from the mold support in a first direction, and a first housing surrounding the mold support and the first terminal structure; and a receptacle connector including a second terminal structure electrically connected to the first terminal structure and a second housing surrounding the second terminal structure and fastened to the first housing, wherein the first housing includes a cylindrical first plug periphery surrounding the mold support and extending in the first direction, and a second plug periphery protruding from the first plug periphery in the first direction. The second plug periphery includes a protruding wall covering at least part of both sides of the first terminal structure and a cover covering an upper surface of the first terminal structure, and exposes a lower surface of the first terminal structure.

Abstract: A connector for a flat cable is provided that prevents damage to a conductor when a terminal is forcedly pressed to a flat cable. The connector for a flat cable includes a retainer that is coupled to flat cable while a portion of the flat cable covers an upper side of a plate-shaped body of the retainer. In addition, a housing is coupled to enclose the body of the retainer and the portion of the flat cable coupled to the body and has a plurality of exposure depressions for exposing exposed conductors at a portion of the flat cable coupled to opposite surfaces of the body to the exterior to connect the conductors to terminals. A position fixing unit is configured to fix a position of the flat cable coupled between the housing and the retainer.
