Definitions

  • the present invention relates to an electrical connector assembly suitable for use in miniature electric/electronic equipment such as cellular telephones, as well as a plug connector and a receptacle connector utilized in the electrical connector assembly.
  • An insulation displacement contact that connects with the core of the wire is connected at the tip of the wire.
  • a crimp contact is crimped onto the shielded outer covering of the wire.
  • the tip of the wire is housed within a first housing to constitute the plug connector.
  • the receptacle connector has a second housing for housing the plug connector, and two second contacts, for respectively contacting the insulation displacement contact and the crimp contact of the plug connector, are provided within the second housing.
  • This connector assembly is configured to connect a single wire.
  • Each of the second contacts has a pair of arms for contacting the insulation displacement contact or the crimp contact from both exterior sides.
  • the connectors when the contacts of the plug connector and the receptacle connector engage each other, the connectors are arranged along a plane parallel to the circuit board. Therefore, the connectors do not protrude from the circuit board, and the assembly is low in height.
  • the contacts of the receptacle connector have flexible arms on both sides of each of the contacts of the plug connector, giving rise to the following problem. That is, the arms require a predetermined range of motion in the width direction of the connector, which is parallel to the circuit board, to secure necessary contact pressure. As a result, the width of the connector becomes large. In the case that the number of terminals of the connector is increased to two, the contacts will require further space in the horizontal direction. Therefore, there is a possibility that such connectors will be difficult to utilize in miniature electric/electronic equipment, in which there are limitations in mounting area.
  • US-A-3710305 describes a solderless electrical outlet for a standard two prong plug.
  • the outlet utilizes a threaded shank effective to complete assembly of the components of the outlet as well as to provide mechanical and electrical connections between an insulated conductor and a female contact.
  • the screw employed for this purpose seats in a threaded well molded into the main body,of the outlet. Its threads cut through the wire insulation prior to penetrating the surface of the conductor.
  • the present invention has been developed in view of the problems described in relation to the abovementioned Japanese publication. It is an object of the invention to provide an electrical connector assembly, especially, a miniature electrical connector assembly, which is low in height, as well as narrow, and also to provide a plug connector and a receptacle connector to be employed in such a connector assembly.

  • the first contacts are provided as a pair, and face in opposite directions to each other, whilst the second contacts are also provided as a pair, and face towards each other, corresponding to the first contacts.
  • the receptacle connector is provided with a cutout on a side wall opposite from the side at which the recess is open, and the plug connector is provided with a protrusion complementary to the cutout, that fits in the cutout during complete engagement with the receptacle connector.
  • the plug connector and the receptacle connector have locking portions that engage each other during engagement of the plug connector and the receptacle connector, the locking portions being formed further toward the side at which the wires are led out than the contact surface and the contact portion.
  • two parallel contact receiving grooves are provided in the plug housing of the plug connector, which are open toward the top thereof the first contacts (contacts of the plug connector) are insulation displacement type contacts and are disposed in the contact receiving grooves and wires are insulation displacement contacted to the first contacts.

This, in addition to the fact that two contact pieces 140 are provided in each contact 11, increases the reliability of the electrical connection. In addition, because the beads 42 and the extended portions 140a protrude toward each other, a "click” is felt when they pass over each other. Complete engagement between the connectors 10 and 100 can also be perceptually recognized by this "click".
  • the contacts of the plug connector 10 may be crimp type contacts.
