Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a wire connector.

[Prior Art] Various electric wire connectors have been manufactured and used in large quantities, but all of these electric wire connectors have complicated structures and are expensive to manufacture.

[Problems to be solved by the invention] Since electric wire connectors are used in large quantities, there was a demand for something that was inexpensive to manufacture and easy to use.
SUMMARY OF THE INVENTION An object of the present invention is to provide a wire connector that is inexpensive to manufacture and easy to use.

[Means for Solving the Problems] In order to solve the above problems and achieve the object of the present invention, the electric wire connector according to the present invention is characterized by being configured as follows. That is, a main body having a wire insertion hole, a base of a pressing spring for a wire housed in the main body, a wire insertion hole formed by folding back from the base, and a wire inserted into the wire insertion hole are locked. A pressing spring having a locking claw, a terminal housed in the pressing spring and having a wire insertion hole and a contact portion with the electric wire inserted into the wire insertion hole, and a main body opening housing the pressing spring and the terminal. It is characterized by consisting of a lid that covers the part.

[Example] Hereinafter, an example of the present invention shown in the drawings will be described in detail. Fig. 1 is a cross-sectional front view showing a state in which an electric wire is inserted into the electric wire connector according to the present invention, and Fig. 2 (A) CB) (
C) (D) is a cross-sectional front view, partially cross-sectional bottom view, right side view, and left side view of the main body; Figures 3 (A), (B), and (C) are a front view, top view, and left side view of the presser spring. Figure, Figure 4 (A) (B)
(C) is a front view, a top view, and a left side view of the terminal.

Figures 5 (A), (B), and (C) are partial cross-sectional front views of the lid;
Partial cross-sectional plan view, left side view, Figure 6 (A) (B) (C
) are a cross-sectional front view, a cross-sectional bottom view, and a partially cross-sectional left side view of the assembled electric wire connector. Here, 1 is the main body,
2 indicates a pusher, 3 indicates a terminal, 4 indicates a lid, and 5 indicates an electric wire.

A wire insertion hole 11 is formed on one side of the main body 1, an opening 12 into which the lid 4 is inserted is formed on the other side, and a space in the center for housing the presser spring 2 and the terminal 3. 13 are formed. Note that the recessed portion indicated by the reference numeral 14 in FIG.
The convex portion of the lid 4 fits into the concave portion indicated by 0. In the present embodiment shown in the drawing, there are three wire insertion holes 11, but two or four or more wire insertion holes 11 may be provided as necessary. It's okay.

The pressing spring 2 of the electric wire 5 housed in the main body l is formed by folding back from the base 21 of the pressing spring and one end of the base 21, and the electric wire inserted into the electric wire insertion hole 22 and the electric wire inserted into the electric wire insertion hole 22. It has a locking pawl 23 for locking 5.

The terminal 3 is housed in the pressing spring 2, and has a contact portion 3 with the wire insertion hole 31 and the wire 5 inserted into the wire insertion hole 31.
It has 2. The contact portion 32 has a pressing spring 2 .

Base 2! It is superimposed with. Further, the terminal 3 has a locking claw 33 which is formed by being folded back from the wire contact portion 32 and locks the wire 5 inserted into the wire insertion hole 31, and between the contact portion 32 and the locking claw 33, , is formed so that the electric wire 5 inserted into the electric wire insertion hole 31 is inserted. Note that the terminal 3 is formed of a conductive material such as copper.

The pressing spring 2 and the terminal 3 housed in the pressing spring 2 are connected to the wire insertion hole 21 and the wire insertion hole 31 formed in one surface of the main body 1 so that the terminal 3 is inserted into the main body 1. 1 is housed in the space 13 through the opening 12. Therefore, main body 1
The electric wire 5 inserted through the electric wire insertion hole 11 is inserted into the locking claw 23
Since the electric wire 5 is locked by the locking pawl 33, the electric wire 5 cannot be pulled out simply by pulling, and the electric wire 5 can fully function as an electric wire connector.

Further, the terminal 3 has a wire contact portion 32 , and the inserted wire 5 is connected to a locking claw 23 and a locking claw 33 in the wire contact portion 32 .
Since they are pressed together with sufficient pressure, electrical conduction is complete and generation of heat can be prevented.

In addition, since the electric wire 5 can be easily pulled out by twisting it, the electric wire connector according to the present invention can be reused.

The lid 4 covers the opening 12 of the main body l in which the presser spring 2 and the terminal 3 are housed.

M4 has an inspection hole 41 for inserting a voltage detection screwdriver, so it is easy to insert the voltage detection screwdriver through the inspection hole 41 and check whether electricity is flowing, as shown in Fig. 1. Can be done.

Further, a convex portion 42 is formed on the outer side of the lid 4, and is formed so as to be elastically engaged with a concave portion 15 formed in the opening 12 of the main body 1. , M4 or the main body 1 is made of an elastic material, such as a synthetic resin such as a thermoplastic resin.

Since the electric wire connector according to the present invention is configured as described above, manufacturing of each component is easy, and in order to assemble the electric wire connector according to the present invention, press and hold the wires from the wire insertion hole 11 of the main body 1. 2 and the terminal 3 housed in the presser spring 2 are inserted, and the opening 12 of the main body 1 is covered with the lid 4.Assembling is easy as it is assembled as shown in Fig. 6. . When using, wire 5-1
The electric wire 5 can be easily connected by making the end bare according to the gauge 14 of the main body l and inserting it into the electric wire insertion hole 11 of the main body l. Further, when removing the electric wire 5, it can be easily removed by twisting the electric wire 5, so that the electric wire connector according to the present invention can be reused.

[Effect of the invention] The electric wire connector according to the present invention is configured as described above,
Since it is used, the manufacturing cost is low and it is easy to use.
