Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a modular electric wire crimping tool used for crimping a flat multicore electric wire to a plug seat (hereinafter referred to as a modular).

To connect a key telephone, electronic device, or other device to a specific device, the connection is made using a clamp-type modular that is crimped to both ends of a flat multicore wire.

Conventionally, to perform the work of crimping a modular on both ends of an electric wire, place a simple modular presser frame on a tabletop press machine on the work desk, fit the modular into this, insert the electric wire into the wire insertion hole of this modular, and then This is held in place with one hand and the press machine is operated with the other hand to crimp the wires and the modular, which can result in variations in the connection between the modular and the wire during the work process, or the work takes time and reduces work efficiency. There was an inconvenience that it was bad.

The present invention has a modular structure as shown in FIG. The fixture 3 is adapted to the structure of the modular, and after inserting the module into it, the modular can be fixed to the fixture using the elastic hook lever. Perform the crimping work, then insert a specially shaped extrusion tool from the back side of the fixture, push up the elastic hook lever stretched on the bottom of the modular body, release the modular fixation from the fixture, and remove it. The purpose is to enable work to be done accurately, easily, and efficiently.

Hereinafter, embodiments of the present invention will be described with reference to the drawings: a sliding surface 3a on the bottom surface of the modular main body 1, a sliding surface 3b for passing the wide piece 2a of the elastic catch lever formed on the bottom surface of the modular main body forming the clamper;
A fixing device 3 in which the sliding groove 3c of the narrow piece 2b of the elastic hooking lever is formed as a stepped groove, and the surface pressing piece 3d of the modular main body is provided protrudingly from the surface of the modular body, which has stoppers formed on both sides of the stepped groove. (Figure 1B) and
This is a modular fixture consisting of an insertion flat plate 4 (FIG. 1C) that can be inserted into the sliding groove 3c of the narrow piece of the elastic hook lever from the back side of the fixture 3.

Since the present invention is constructed as described above, how to use it is to set the fixture according to the present invention on a press machine (not shown) placed on a work desk.

Next, from the modular insertion opening of the fixture 3 that has a stepped groove, place the elastic hook lever 2 of the modular 1 downward, and place the bottom surface of the modular body 1 on the sliding surface 3a of the bottom of the modular body. 2a
The wide piece passing sliding surface 3b forming the clamper
When the narrow piece 2b of the elastic hooking lever comes into contact with the sliding groove 3c and is pushed and slid into the fixture 3 while being pushed by hand, the front end surface of the modular body is formed on the surface pressing piece 3d of the modular body. When the wide piece 2a of the elastic hooking lever hits the stopper, it passes through the sliding surface 3b.
The sliding surface 3 passes through while being pushed up against elasticity.
When it is pushed to the clamper point b, it falls into the clamper due to elastic repulsion, and is caught by the clamper and stopped. (See Figure 2) At this time, the modular main body 1 is in contact with the surface push piece 3d protruding from the fixture whose surface has a stepped groove, so the modular is firmly fixed within the fixture. It is in a state of

Next, insert the bare wire part (not shown) of the required flat multicore wire into the flat multicore wire insertion opening 1a of the modular with the bare wire part (not shown) facing forward, and press the metal terminal 1b arranged on the modular with a press machine. When pressed, the metal terminal 1b disposed on the modular presses the bare wire portion of the wire inserted from the wire insertion opening 1a of the modular main body, and the metal terminal 1b is crimped and connected to the wire. After crimping and connecting the electric wires, insert the flat insertion plate 4 arranged on the back side of the fixing device into the sliding groove 3 of the narrow piece of the elastic catch lever and slide it along the bottom of the groove. The flat plate 3 pushes up the narrow piece 2b as well as the wide piece 2a of the elastic hook lever, and the wide piece is pushed up from the hooking surface of the clamper against the elasticity of the wide piece, and the wide piece of the elastic hook lever is pushed up from the clamper. It comes off. Further, when the flat insertion plate 4 is slid along the bottom surface of the groove 3c, the modular is pushed out from the fixture and removed.
(See Figure 3) The structure of the stepped groove of this fixture is manufactured in a manner that corresponds to the size and shape of the existing modular, and the stopper has a screw 5 for position adjustment to adjust deviations due to differences in the modular. Because this fixing device can accurately fix the modular and ensure the wires are crimped using a press, it is possible to simplify the manual work of the deceased and achieve the goals of improving quality and work efficiency. .

This fixture is not only used for manual processes, but also can be used in automatic machines to automatically crimp flat multi-core wires into modular pieces, resulting in excellent improvements in terms of economy and quality control. It is possible.
