Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a contact having a wire connection portion.

2. Description of the Related Art As an example of a conventional contact of this kind, a pin contact as shown in FIGS. 1 and 2 is known. That is, it consists of a contact part 1 that is inserted into and makes contact with a socket contact to be connected, a wire connection part 3 that connects an electric wire 2, and a locking part 5 that is locked to a housing 4. After soldering 6 the core wire 2a of the electric wire 2 to 3, the contact portion 1 is press-fitted from one end of the pin hole 7 of the housing 2 to protrude from the other end, and the retaining piece 5a of the locking portion 5 is engaged. The locking protrusions 5b are respectively locked in the locking holes 8 and the ends of the locking grooves 9 to be installed in the housing 4. The wire connection part 3 for such a conventional pin contact is attached to the bottom plate 3a.
The electric wire 2 could not be temporarily fixed to the electric wire connection part 3 because the electric wire 2 was only formed by opposing side walls 3b, 3b connected at right angles from both side edges of the bottom plate 3a. For this reason, when applying the solder 6, the positioning of the electric wire 2 and the electric wire connecting portion 3 becomes unstable, and the work required to apply the solder 6 and fix both 2 and 3 is troublesome.

The present invention has been devised to eliminate the above-mentioned drawbacks, and provides a contact that can temporarily fasten electric wires and facilitates the soldering work of the electric wires to the wire connection portions. That is, the contact according to the present invention includes a bottom plate, opposing side walls connected at an acute angle to both side edges of the bottom plate, and a cut-and-raised piece cut upward from the bottom plate. The present invention is characterized in that an electric wire connecting portion is configured so that the electric wire can be press-fitted between the side wall and the cut-and-raised piece for temporary fixation.

Hereinafter, one embodiment of the present invention is shown in Figs. 3 to 6.
The explanation will be based on the drawings up to the figure. Figures 3 and 4
In the figure, 10 is a pin contact, and this pin contact 10 is integrally formed by applying tin plating or the like to the outer surface of a conductive material such as brass. The pin contact 10 includes a cylindrical contact portion 11 with a closed tip, a locking portion 15 consisting of a retaining piece 15a and a locking protrusion 15b connected to the other end of the contact portion 11, and this locking portion. 15, and a wire connection part 13, which is unique to the present invention, and connected to the wire connection part 15. The electric wire connection portion 13 includes a bottom plate 13a and a bottom plate 13.
The side wall 13b is made up of side walls 13b, 13b connected at an acute angle (for example, 70 degrees) to both side edges of the bottom plate 13a, and a triangular cut-and-raised piece 13c cut upward from the bottom plate 13a. , 13b, their central portions 13d are butted against each other as shown in FIG. 4, and notches 13e and 13f are formed in front and behind the abutted central portions 13d. The bottom plate 13a and the side walls 13b, 13
A space surrounded by b and the notch 13e forms an insertion opening 20 for the electric wire 2. When the electric wire 2 is press-fitted from the insertion opening 20 in the direction of the arrow in the figure, the core wire portion 2a of the electric wire 2 is cut and raised into the cut-and-raised piece 13c.
As shown in FIG. 6 and FIG.
The core wire portion 2a is pressed and temporarily fixed by the cut-and-raised piece 13c. After the electric wire 2 is temporarily fixed to the electric wire connection part 13 in this way,
The core wire portion 2a and the wire connection portion 13 are formed by a notch portion 13f.
Complete electrical connection is achieved by soldering from 6 to 6. In addition, in FIGS. 6 and 7, when the electric wire 2 is further press-fitted, the covering part 2 of the electric wire 2
b is pressed and temporarily fixed by the side walls 13b, 13b and the cut and raised piece 13c.

In the above embodiments, a pin contact, which is a male type contact, was explained as an example, but the present invention is not limited to this, and can also be applied to a socket contact, which is a female type contact, as long as it has a wire connection part. It is possible.

The contact according to the present invention, as mentioned above,
A wire connection portion is formed by a bottom plate, opposing side walls that are connected to each other at an acute angle on both sides of the bottom plate, and a cut-and-raised piece cut and raised from the bottom plate, and a wire connection portion is formed between the side wall and the cut-and-raised piece. Since the electric wire can be press-fitted between the two and temporarily fixed, alignment of the electric wire and the electric wire connection part becomes easy, and the soldering work becomes extremely easy. This is particularly effective when connecting wires to each of the wire connection portions of a large number of contacts by soldering.
