Description

  The present invention relates to a crimp contact that crimps and clamps a wire, in particular, a crimp contact suitable for use in a waterproof connector, and a connector equipped with the contact.

  In general, the structure of a conventionally known crimp contact (hereinafter simply referred to as a contact) includes a contact contact portion that is electrically and mechanically connected to a corresponding contact, and a crimp portion that is crimped and clamped to a wire. The crimping portion includes a wire barrel and an insulation barrel.

  Here, the wire barrel is electrically and mechanically connected to the conducting wire, and the connection length of the wire barrel is defined in order to ensure the allowable current of the contact.

  In addition, in order to ensure that the required length of the conducting wire for connection is always connected to the wire barrel, the end of the conducting wire is not aligned with the end surface of the wire barrel, but is projected from the end surface for safety design. It ’s long and aligned.

  Here, when the conducting wire is crimped in a state where the long conducting wire terminal protrudes from the end surface of the wire barrel, the protruding portion of the conducting wire is unrolled, and the phenomenon of flaking occurs. When such a contact with broken conductors is used for a normal connector, the reliability in terms of quality is lowered. On the other hand, when it is used for a special application, for example, a contact of a waterproof connector, a new problem may occur in terms of performance.

  That is, such a terminal of a broken conductor may pierce a sheet of, for example, a silicone rubber that is a waterproof seal and penetrate the sheet, thereby causing a problem of impairing the waterproof performance of the connector.

  Here, “separation” means a state in which a plurality of strands constituting a conducting wire are unwound and are separated.

  As a technique for solving this problem, a technique described in JP-A-11-135163 is known as a contact mainly used for a waterproof connector. According to the technique described herein, referring to FIG. 10, the contact 200 includes a contact portion 211 that is electrically and mechanically connected to a corresponding contact, and a crimp portion that crimps a wire. The crimping portion includes a wire barrel 212 and an insulation barrel 213. In addition, the contact is characterized in that an arch-shaped portion 214 is provided around the coaxial center between the contact portion 211 and the wire barrel 212. The arch-shaped portion 214 sandwiches the end of the conductive wire protruding from the end face of the wire barrel 212 in a state of being bundled and housed.

Certainly, by providing the arch-shaped portion 214, it is possible to regulate the variation of the conductive wire, and when assembled to the waterproof connector, there is no risk of damaging through the silicone rubber sheet used as a waterproof seal material, so you can rest assured It can be assembled efficiently.
JP-A-11-135163

  However, by providing the contact with an arch-like portion, the total length of the contact becomes long, and the miniaturization of the connector to which the contact is attached is hindered. Furthermore, this increases the size of the device incorporating this connector, and goes against the trend toward miniaturization of electrical, electronic products and electronic components in general.

  Accordingly, an object of the present invention is to provide a contact capable of crimping a conducting wire to the contact so that the end of the conducting wire does not vary without extending the total length of the contact.
