DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crimp terminal having a round tip.

[0002]

2. Description of the Related Art FIG. 3A is a plan view of an example of a conventional crimp terminal, FIG. 3B is a side view of FIG.
Is a plan view of a second conventional example, and (b) is a side view of FIG.

A conventional crimp terminal has a round tip and a closed end as shown in FIG. 3 as a first example, or a U-shaped tip as shown in a second example in FIG. Open-ended shapes and the like have been selectively used in accordance with the requirements of the use conditions.

[0004]

SUMMARY OF THE INVENTION The above-mentioned first example and second example
In comparison with the above example, the former has an advantage that the connection of the terminal is hard to be disconnected even if the screw for crimping becomes loose during use. Therefore, in the first example, the tip having a round shape and a closed shape is more frequently used. However, it takes time to remove the terminal part due to the deterioration of the screw part with the passage of time. At that time, depending on the type of the connection partner, it is often necessary to connect the open-ended terminal and the wire in order to newly change to a U-shaped one, for example.

Accordingly, an object of the present invention is to provide a crimp terminal having a round tip with a front-opening terminal and a wire when it is necessary to change the crimping terminal into a front-opening shape before or after use. Even if the terminal is not changed by changing the connection, it is easily cut at the two grooves by providing in advance two grooves of appropriate depth from the bolt hole toward the tip on both sides of the tip. An object of the present invention is to provide a crimp terminal with a round tip that can be easily formed into an open shape.

[0006]

The round crimp terminal of the present invention has a bolt insertion hole at the center of the round crimp terminal for crimping the terminal to a connection partner. In each of the terminals, two grooves are engraved on the both surfaces of the round tip in a direction substantially parallel to the tip from the hole at intervals substantially equal to the diameter of the hole.
It is characterized in that the tip is easily cut off immediately before or after use of the terminal, and can be deformed into a crimp terminal having a front open shape.

It is preferable that each groove has a V-shaped cross section and a depth within a range of 15% to 40% of a thickness.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1A is a plan view of an embodiment of a crimp terminal with a round tip of the present invention, FIG. 1B is a side view of FIG. 1A, and FIG. 1C is a side view of FIG. FIG. 2D is a plan view in which the front end portion is cut from the position of the groove to form a front-opened shape, FIG. 2D is a side view taken along the arrow in FIG. 1C, and FIG. FIG. 2B is a plan view of the connected state, and FIG. 2B is a plan view in which the tip of FIG.

As shown in FIGS. 1 and 2, a round tip crimp terminal 1 of the present invention has a bolt insertion for crimping connection of the terminal 1 to a connection partner 5 at the center of a round tip 2. The passage hole 2b is opened.

On both sides of the rounded tip, two grooves 2a ₁ , 2a ₂ and 2a ₃ , 2a ₄ are cut in a direction substantially parallel to the tip of the hole 2b with an interval L substantially equal to the diameter of the hole 2b. As a result, as shown in FIGS. 1 and 2, the front end portion 2 is easily cut and has a front-opening crimp terminal having an opening 2c immediately before or once after use of the terminal 1. It can be transformed to 1 '.

The grooves 2a ₁ , 2a ₂ and 2a ₃ , 2
a ₄ in cross section a V-shaped, about 20 of a thickness of depth
25%. If the depth is reduced, the intended cutting becomes difficult, and if the depth is increased, the strength is reduced.
% May be desirable.

[0013]

As described above, according to the present invention, two grooves from the bolt hole at the tip to the tip with a spacing substantially equal to the diameter of the hole are formed on both surfaces of the tip of the round tip crimp terminal. By providing the terminal in advance, the terminal can be easily deformed into a front-opening shape depending on the application, and therefore, there is an effect that a round tip crimp terminal with high on-site work efficiency can be provided.
