Description

  The present invention relates to a crimp terminal that is fixed by screw tightening by inserting a tip portion into a fitting portion of a screw tightening type terminal block.

  Conventionally, as shown in FIG. 3, crimp terminals are respectively fixed to the ends of a plurality of communication lines and the like, and the respective crimp terminals are inserted into the respective insertion openings (fitting portions 12) of the screw-tightening type terminal block 11. However, fixing with a strong contact pressure with a screw is performed. At this time, the crimp terminals fixed to the tips of the plurality of wires are first lightly tightened by inserting rod-like or plate-like tip portions into the respective insertion openings (fitting portions 12) of the screw-tightening type terminal block 11. In general, after the entire routing process (preliminary process or the like) is completed, the screw tightening is properly performed (retightening is performed). The prior art of FIG. 3 will be briefly described below.

FIG. 3 is an explanatory diagram of the prior art.

The tip was temporarily tightened and then finally tightened.

  In the crimp terminal fixed to the tip of the conventional wire in FIG. 3 described above, since the plate-like or rod-like portion at the tip of the crimp terminal inserted into the fitting portion 12 is performed by pressure due to screw tightening, temporary fastening is difficult. Therefore, there is a problem that workability is poor due to omission during the entire routing process or the like. In particular, when the fitting portion is facing downward, when the entire routing process or the like is performed with the plate-like or rod-like portion of the tip portion of the plurality of crimp terminals inserted into the fitting portion 12 and temporarily tightened with the screw 13 There was a problem that the workability was extremely poor.

  Further, the conventional screw-clamping type terminal block has a problem that workability is poor because there is no structure that generates a repulsive force like a washer in the screw part and increases the fitting strength when temporarily tightened.

  In order to solve these problems, the present invention fits in a state in which the tip of the crimp terminal fixed to the tip of the wiring is V-shaped (or U-shaped) or one side is slightly shortened and the tip is closed. After being inserted into the part and temporarily tightened, routing processing and the like are performed, and then finally tightened with screws.

  In the present invention, the tip end portion of the crimp terminal fixed to the tip end of the wiring is V-shaped (or U-shaped) or further slightly shortened, and inserted into the fitting portion with the tip end closed, and then temporarily tightened. After performing the routing process, etc., by tightening with screws, it is possible to temporarily tighten the crimp terminal fixed to the tip of the wiring to the fitting portion and improve the workability of the routing process.

  In the present invention, the tip end portion of the crimp terminal fixed to the tip end of the wiring is V-shaped (or U-shaped) or further slightly shortened, and inserted into the fitting portion with the tip end closed, and then temporarily tightened. After performing routing processing, etc., it was finally tightened with screws, and a crimping terminal fixed to the tip of the wiring was temporarily tightened to the fitting portion, thereby improving the workability of routing processing and the like.
