Abstract: Proposed is a connector apparatus with a switch for improving contact reliability, the connector apparatus being capable of enabling an operator to electrically test proper coupling of a connector position assurance member. When the connector position assurance member is completely coupled to a first housing, a pair of switches are stably brought into contact with each other in a state of being inserted into a switch guide recess formed in a second leg portion. Therefore, the pair of switches can be safely protected from foreign substances, etc., thereby improving the contact reliability of the first and second switches.

Abstract: A shield and locking type board to board connector functioning to connect a first board and a second board to each other, the connector including: a first connector unit having both a first base and a first terminal; a second connector unit having a second base and a second terminal; two shield members each having a shell shape, the shield members respectively provided on front and rear bases facing the second base such that the shield members arrest EMI (electromagnetic interference) noise; and a locking member provided in the second connector unit so as to prevent the first connector unit from being removed outward by an outward movement thereof after the first connector unit is combined with the second connector unit in a close contact state.

Abstract: The present invention relate to a socket for a nano SIM card first to third connection parts arranged in a transverse direction, and fourth to sixth connection parts arranged in parallel with the first to third connection parts. The socket comprises: first to sixth terminals each comprising a contact part configured to be brought into close contact with an associated one of the connection parts of the nano SIM card and a soldering part configured to be soldered to a print circuit board; a housing comprising through-openings for first to sixth contact parts, which are formed at positions corresponding to the positions of the respective connection parts of the nano SIM card when the nano SIM card is inserted into the socket; and a cover coupled to the housing to define a space between the housing and the cover so that the SIM card is inserted into the space.

Abstract: Disclosed herein is an electric connector which is used for transmitting electromagnetic signals. The electric connector of the present invention includes a main body which has upper and lower guide bodies extending predetermined lengths, with an insertion slot formed in a first surface of the main body. The electric connector further includes a conductive cover which surrounds an outer surface of the main body. An edge of a part of the conductive cover, which faces the contact part of the main terminal contact and is placed at a position adjacent to the first surface of the main body, is bent into the insertion slot. The present invention has a structure to meet standard requirements and prevents an undesired part from contacting a plug connector, thus reducing the incidence of malfunction.
