Abstract

PROBLEM TO BE SOLVED: To reduce kinds of crimp terminals for connecting plural electric wires to one connection position of a terminal board to facilitate management and to prevent drop in efficiency by branching plural connection parts from a single fixing part. SOLUTION: Crimp terminals 1, 11 to which electric wires 2 are connected are previously formed in a specified shape and fixed to a terminal board 4 with a screw 5. The crimp terminals 1, 11 are preferable to be formed in the shape capable of preventing interference between adjacent crimp terminals 1, 11 or the electric wires 2 connected to crimp terminals 1, 11. Forming of the shape of the crimp terminals 1, 11 may be conducted after the crimp terminals 1, 11 are fixed to the terminal board 4. By forming the shape of the crimp terminals 1, 11, even if the distance A between the inner surface of a casing for storing an electronic apparatus and the terminal board 4 is narrow, wiring can be facilitated. The fixing part is preferably twisted about 90 degrees between the fixing part to the terminal board and the branching position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a crimp terminal for connecting a terminal block to an electronic device, and in particular, to a terminal block having a limited number of wire connection positions. The present invention relates to a crimp terminal suitable for connecting a larger number of electric wires.

[0002]

2. Description of the Related Art As a crimp terminal for connecting a plurality of electric wires to one connection position of a terminal block, for example, Japanese Patent Application Laid-Open No.
A crimp terminal disclosed in -50845 has been proposed.

[0003] In this crimp terminal, when the thickness of a mounting portion screwed to a terminal block is set to be substantially equal to the thickness of a connection portion to which an electric wire is crimped, and a plurality of crimp terminals are vertically fixed and fixed. The crimp terminals are configured to be in a parallel horizontal state.

According to such a crimp terminal, a plurality of electric wires can be easily connected to one connection position of the terminal block by changing the length of the screw.

[0005]

However, since it is necessary to prepare crimp terminals according to the thickness of the electric wire connected to the terminal block, the number of types of crimp terminals increases, and the management thereof becomes only complicated. Instead, when attaching a crimp terminal to an electric wire, it is necessary to check the thickness of the electric wire and the type of the crimp terminal, which reduces workability.

In view of the above circumstances, an object of the present invention is to reduce the types of crimp terminals for connecting a plurality of electric wires to one connection position of a terminal block, to facilitate management and to reduce workability. An object of the present invention is to provide a crimp terminal that does not cause a crimping.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, an electric wire is crimped to a mounting portion having a through hole for fixing to a terminal block. In the crimp terminal in which the connection portion was formed, a plurality of connection portions were integrally formed so as to branch off from a single attachment portion.

[0008] The invention described in claim 2 is the first invention.
In the invention described in (1), the attachment portion is twisted by approximately 90 degrees between the attachment portion to the terminal block and the branching position of the connection portion.

[0009] The invention described in claim 3 is the first invention.
Alternatively, in the invention according to claim 2, the connection portion is twisted by approximately 90 degrees between the branch position and a position where the electric wire is crimped.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described with reference to the drawings. 1 and 2 show that the present invention
FIG. 1 is a plan view of a crimp terminal according to the present invention, and FIG. 2 is a perspective view showing a use state of the crimp terminal according to the present invention.

In FIG. 1, reference numeral 1 denotes a crimp terminal, which is formed integrally with a single mounting portion 1a and a plurality of connecting portions 1b, and has a through hole 1c in the mounting portion 1a. Reference numeral 2 denotes an electric wire, which is connected to the crimp terminal 1. Reference numeral 3 denotes an insulating tube which covers a connection portion between the crimp terminal 1 and the electric wire 2. 4 is a terminal block.
5 is a screw. Reference numeral 11 denotes a crimp terminal in which a single attachment portion and a single connection portion are integrally formed.

With such a configuration, the crimp terminals 1 and 11 to which the electric wires 2 are connected are shaped into a required shape in advance and fixed to the terminal block 4 with screws 5 as shown in FIG. At this time,
Between adjacent crimp terminals 1, 11 or between crimp terminals 1, 1
In order that each electric wire 2 connected to 1 does not interfere,
The crimp terminals 1 and 11 are preferably shaped.

The crimp terminals 1 and 11 may be shaped after the crimp terminals 1 and 11 are attached to a terminal block. Also, by shaping the crimp terminals 1 and 11,
Wiring can be performed even when the distance A between the inner surface of the housing housing the electronic device and the terminal block 4 is small.

FIGS. 3 and 4 show a second embodiment of the present invention. FIG. 3 shows a crimp terminal according to the present invention, wherein (A) is a plan view and (B) is a side view thereof. FIG. 4 and FIG.
FIG. 3 is a perspective view showing a use state of the crimp terminal according to the present invention.

In FIG. 1, reference numeral 1 denotes a crimp terminal, which has a single mounting portion 1a and a plurality of connecting portions 1b integrally formed, a through hole 1c formed in the mounting portion 1a, and a mounting portion 1a and a branch portion 1a.
It is twisted approximately 90 degrees between d. The other components are the same as those in FIGS. 1 and 2 and are denoted by the same reference numerals.

With this configuration, when the crimp terminal 1 is fixed to the terminal block 4 with the screw 5 as shown in FIG. 4, the rows of the connection portions 1b of the adjacent crimp terminals 1 do not interfere with each other. Instead, they can be arranged in parallel at the same interval as the interval between the screwing portions of the terminal block 4.

As described with reference to FIG. 2, when the space between the housing and the terminal block is small and it is necessary to bend the crimp terminal 1, the twisted portion of the crimp terminal 1 is used and one of them is used. , The connecting portion 1b can be bent upward, and the other can be bent such that the connecting portion 1b moves downward. At this time, the crimp terminal 1 may be bent in a direction to remove the twist.

The root of the connecting portion 1b of the crimp terminal 1 is twisted by approximately 90 degrees, and the connecting portion 1b is further moved from that position.
May be bent.

In each of the above embodiments, the case where the single mounting portion 1a and the three connecting portions 1b are integrally formed has been described, but the number of connecting portions 1b may be two or more. Further, the positions of the mounting portion 1a and the connecting portion 1b may be such that the mounting portion 1a is biased toward one of the arrangement of the plurality of connecting portions 1b.

[0020]

As described above, according to the present invention, since a plurality of connection portions are provided for a single mounting portion, a crimp terminal for connecting a plurality of electric wires to one connection position of a terminal block. The number of types is reduced, the management is facilitated, and the workability is not reduced.
