Description

  The present invention relates to an electrical connector. In particular, the present invention relates to the structure of an electrical connector provided with a press contact for connecting the ends of electric wires by press contact.

  In recent years, office machines such as a copier, a facsimile machine, or a multifunction machine that integrates these machines have become widespread. These office equipments electrically connect a plurality of board connectors in which a wiring harness in which electric wires and connectors are integrally assembled is installed.

  The connector used for the wiring harness described above includes a press contact for connecting the end of the electric wire by press contact. In this press contact, a contact connection portion and a press contact connection portion connected to the mating contact are integrally formed.

  In general, the press contact connection portion has a slot having a pair of press contact blades. When the electric wire is inserted into the slot, the pair of press contact blades pushes away the insulating coating of the electric wire. The pair of press contact blades deforms a single-wire conductor (or a twisted strand) to enable solderless connection that provides electrical connection.

  As such a pressure contact and an electrical connector, a pressure contact that can secure an elastic contact state with the electrical connector even if the outer shape of the connector is very small and has a large number of poles, and an electrical connector using the same are invented. (For example, refer to Patent Document 1).

The press contact according to Patent Literature 1 includes press contact blades arranged in duplicate, and a pair of elastic contact pieces respectively connected to the outer side of one press contact blade. The two press contact blades are coupled and opposed on the base side so as to form a slot for receiving the electric wire on the inner side. When the electric wire is inserted into the slot, the two press contact blades cut the insulation coating and press the core wire. The elastic contact piece has an elastic pinching portion extending toward the opposite side to the opening of one slot. The elastic clamping portion has a pair of contact portions and is formed in a tapered shape that becomes narrower toward the contact portion.

  In the press contact according to Patent Document 1, press contact blades that are arranged in two stations to be a press contact portion and a pair of elastic contact pieces to be a contact connection portion are arranged coaxially. One pressure contact blade is disposed adjacent to the pair of elastic contact pieces. When the outer shape of the press contact contact configured as described above is further reduced, it is considered that the strain when the electric wire is pressed contacts the elastic contact piece.

  When an electric wire is inserted into a slot provided with a pair of press contact blades, the pair of press contact blades pushes away the insulation coating of the electric wire. Distortion occurs at the base of the press contact blade.

  In the press contact according to Patent Document 1, one press contact blade is disposed close to the pair of elastic contact pieces, so that the pair of elastic contact pieces can be deformed in the opening direction to maintain a predetermined contact pressure. There are concerns that it will be difficult. Therefore, there is a demand for an electrical connector including a minute pressure contact that does not affect the contact connection portion even when the electric wire is pressed.
