JPH05326101A - Wire insertion tool and its connector - Google Patents

Abstract

PURPOSE:To prevent a wire, pushed into the insertion slot of a connector through a push-in bar, from falling away out of the insertion slot. CONSTITUTION:A wire 3 is held against the insertion slot 4 of a connector 1. A tool 2 is provided with a push-in bar 5 and a narrowing blade 6. The wire 3 is pushed into the insertion slot 4 by the push-in bar 5. Thereafter, the insertion slot 4 accepting the wire 3 is pushed by the narrowing blade 6 so that an opening side is narrowed.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool-electrical wire connector used for wiring connection work.

[0002]

2. Description of the Related Art In a conventional insertion type connector, the insertion groove is widened when the electric wire is inserted, and the holding force for pulling the electric wire in the insertion direction is reduced.

[0003]

However, the conventional connector has a complicated structure, a processing method, and a sandwiching means, and thus the manufacturing cost of the connector is high and the workability of the connection work is poor. There was a problem, and as a result, the electric wire might come off. An object of the present invention is to provide a pinching tool and a connector that prevent the electric wire from falling off when the electric wire is pulled toward the opening of the nipping groove of the nipping type connector.

[0004]

In order to achieve the above object, the wire inserting tool and the connector of the present invention are achieved as follows, respectively. (1) In a pinching tool for pushing and fixing an electric wire with a pushing rod to a connector having a plurality of inserting grooves formed in parallel, in order to narrow the inserting groove, both sides of the pushing rod are integrated with the pushing rod. It has a narrow blade. (2) In order to use the inserting tool, a groove into which the narrowing blade is inserted is provided between the plurality of inserting grooves in the connector.

[0005]

According to the present invention, narrowing blades are provided on both sides of the wire pushing rod for narrowing down the connector having a plurality of inserting grooves formed in the longitudinal direction, and the narrowing blades are inserted between the inserting grooves. Since the groove is provided, it is possible to improve the reduction of the wire holding force against the pulling of the wire toward the opening of the insertion groove of the insertion type connector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to FIGS. In the figure, 1 is a connector, 2 is a tool used for connection work, 3 is an electric wire to be connected, 4 is a nipping groove, 5 is a pushing rod, and 6 is a narrowing blade. The sandwiching process is as follows. First, as shown in FIG. 1, the insertion groove 4 of the connector 1
Insert the wire 3 into. As shown in FIG. 2, the electric wire 3 put in the inserting groove 4 is pushed by the pushing rod 5. From the time when the coating of the electric wire 3 is broken by the edge of the insertion groove 4 and the core wire 3a is inserted and pushed into the stroke A, FIG.
As shown by, the narrowing blade 6 pushes and narrows the insertion groove 4 of the connector 1, and when pushed to the stroke B, the connection is completed.
Then, as shown in FIG. 4, the tool 2 is pulled out from the connector 1. When inserting the electric wire 3 with the push rod 5, at the same time as inserting the electric wire 3, the connector 1 is narrowed and the blades 6 are pressed from both sides to narrow the insertion groove 4, thereby compressing the core wire 3a of the inserted electric wire 3. Then, in that state, the connector 1 is permanently deformed, and the electric wire 3 is firmly held. As a result, the contact force between the core wire 3a and the connector 1 increases due to the improvement of the holding force against the pulling of the connector 1 toward the opening and the compression of the core wire 3a. Also, connection work time and connector 1
Since it does not affect the manufacturing cost, the improvement can be made only by the cost for changing the connector 1 and the cost for making the connecting tool. In the connector 1 that connects a plurality of lines, grooves are added between the sandwiching grooves 4. When the narrowing blade 6 is inserted into the groove, the connector 1 that connects a plurality of wires, which cannot sufficiently compress the core wire by pushing and narrowing from both sides of the connector 1, also has a sufficient core wire 3a.
Can be compressed. According to this embodiment, the insertion groove 4
Since the wire is narrowed after the wire is inserted, the holding force of the wire 3 is improved, and the core wire 3a is compressed to obtain excellent contact resistance.

[0007]

According to the present invention, the inserting groove can be narrowed by the same tool after the electric wire is inserted, and the electric wire can be prevented from falling off.
