Description

[Detailed description of the invention] Purpose of the invention: To provide a simple tool for attaching terminals to flat conductors (particularly flat cables for undercarpet wiring).

Problems to be Solved Conventionally, when attaching terminals to the conductors of flat cables, a large amount of pressure is required when caulking, so manual tools or hydraulic tools with large handles are used, which are large and heavy. It was also heavy and inconvenient to handle.

Structure of the invention A punch and an anvil for crimping the terminal are provided with screws, a flat cable and the terminal are held between the punch and the anvil, and the terminal is crimped by screwing the punch into the anvil.

Effect of the invention: A hole is drilled in advance in the flat cable, an eyelet-shaped terminal is temporarily inserted, and the cable is placed on the anvil.

Insert the male screw of the punch into the cylindrical part of the terminal and screw it into the female screw of the anvil.

Next, the punch head is rotated using a torque wrench, and the punch is screwed onto the anvil to crimp the terminal. After crimping, reverse the punch and remove.

At this time, by setting a torque that generates the pressure necessary to connect the flat conductor and the terminal, the crimp strength of the terminal can be easily made uniform.

Embodiment In the embodiment shown in FIG. 1, the punch 10 has a hexagonal nut-shaped head, a recess 12 for caulking one side of the eyelet-shaped terminal on the lower surface of the head, and a recess 12 on the lower cylindrical portion. A male thread 13 is provided, and the anvil 20 is provided with a recess 21 and a female thread 22 for caulking the opposite side of the terminal.

To screw this punch into the anvil, use a torque wrench and crimp the terminal to the cable with the set torque.

In this embodiment, the punch is provided with a male screw, but the male and female screws may be reversed, and the anvil may be screwed into the punch.

Workability will be improved by incorporating the punch and anvil into a handle-like arm.

Naturally, the tool for screwing is not limited to a torque wrench, and tools driven by electricity, fluid, etc. may also be used.

In addition, the structure of the punch is a combination of a part for caulking the terminal and a rotating part for screwing in, so if the part to be caulked does not rotate, caulking can be done without rotating the terminal, improving work efficiency. be able to.

Note that the crimping height can also be regulated by a protrusion or the like between the punch and the anvil.

In addition, if the tool is provided with a threaded portion apart from the crimping portion, it can be applied to terminals other than eyelet-shaped terminals.

In the embodiment, a case is shown in which there is one cable, but the same applies to a plurality of cables.

Effects of the invention According to the invention of the present application, it is possible to crimp a punch or anvil using a torque wrench, and it is simple and lightweight without the need for special tools.It is also easy to set the crimp torque, and it is possible to crimp a punch or anvil using a torque wrench. The work can be done without being limited by the size that can be crimped from the cable end.
