DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a press contact of an electrical connector comprising a metal plate having a press contact groove into which a cable is press-fitted as it is.

[0002]

2. Description of the Related Art As shown in FIG. 4, a contact 10 made of a metal plate 11 is formed at a tip of a contact 10 made of a metal plate 11 by punching a U-shaped press contact groove 12 with a press or the like. The electric wire / cable 20 with the outer cover 21 covered in the groove 12 is press-fitted as it is, and at this time, the two metal plate portions 11a, 11
As shown in FIG. 2A, a method in which the outer skin 21 is cut into the inner conductor 22 and the inner conductor 22 is pressed against the press contact groove 12 has already been proposed.

According to the press contact of this type, the connection with the electric wire / cable 20 can be performed simply by press-fitting the electric wire / cable 20 with the outer cover. Connection is possible.

[0004]

However, the above structure has the following problems. First, in the electric wire / cable 20 to be used, if the outer cover 21 is thick or has a high strength for the purpose of improving the insulation properties and the withstand voltage, it is difficult to simply press the outer cover 21.
Is not broken and cannot be press-fitted.
Incomplete tearing of No. 1 causes a problem such as poor contact.

For this reason, the outer cover 2 on the press-fit end side of the press-contact groove 12 is provided.
It is conceivable to make the metal plate 11 itself forming the contact 10 thinner so that the biting into 1 is improved.
If the thickness is reduced, the contact area with the conductor 22 of the electric wire / cable 20 is reduced, so that a new problem that a large current capacity (conductivity) cannot be obtained arises.

The present invention has been made to solve such a problem. Basically, a blade portion for cutting the outer skin is provided on the press-fitting end side of the press-contact groove, and the blade portion is thick. An object of the present invention is to provide a press-contacting contact of an electrical connector that can easily bite the outer skin or the outer skin having high strength.

[0007]

The feature of the present invention resides in a press-contact contact of an electric connector comprising a metal plate having a press-contact groove into which an electric wire or cable with a jacket is press-fitted as it is. A press-contact contact of an electrical connector in which a blade portion for cutting an outer skin is provided in a metal plate portion on a press-fit end side of the press-contact groove.

[0008]

1 to 3 show several embodiments of a press contact of an electric connector according to the present invention. The basic structure is the same as that of FIG. Similar, but both metal plate portions 11 on the press-fit end side of the press-contact groove 12
A and 11a are different in that a blade portion 13 for cutting the outer skin is provided.

In the press contact 10A of the electric connector shown in FIG. 1, both metal plate portions 11a, 11 of the press contact groove 12 are provided.
a is provided with tapered blades 13, 13 extending from one edge near the edge to the apex, and tapered outer guides 14, 14 are provided on the left and right sides of the press-contact groove 12 on the opening side. is there. For this reason, the press contact groove 1 of this contact 10A
2, if the electric wire / cable 20 with the outer skin is press-fitted as shown in FIG.
As a result, the conductor 22 is easily bitten and broken, and the internal conductor 22 is smoothly pressed into the press-contact groove 12. Also, at this time, since the outer skin guiding portions 14 and 14 are provided on the left and right sides of the opening side of the press contact groove 12, when the wire / cable 20 with the outer skin is to be press-fitted, the outer skin 21 is moved by the outer skin guiding portions 14 and 14. 14
The blades 13, 13
Biting can be facilitated. In forming the blade portions 13, 13, a crushing process or the like may be added to the pressing process of the press-contact groove 12, and the outer skin guiding portions 14 may be formed.
It may be performed at the same time as the processing of the press-contact groove 12.

The press contact 10B of the electrical connector shown in FIG. 2 is the same as the press contact 10A of FIG. 1 except that the outer skin guiding portions 14 are omitted. If so, it has the same effect as above.

In the case of the pressure contact 10C of the electric connector shown in FIG. 3, both metal plate portions 11a of the pressure contact groove 12 are provided.
11a are provided with tapered blade portions 13... From the edge portions on both sides to the apex portion. In this case, the apexes of the two metal plate portions 11a, 11a of the press contact groove 12 have a thinner and sharper shape. Therefore, as shown in FIG. When press-fitted, the outer skin 21 is more easily bitten and broken by the left and right more sharp blade portions 13..., And the inner conductor 22 is smoothly pressed into the press-contact groove 12. of course,
Also in this case, the outer skin guiding portions 14 and 14 can be provided on the left and right sides on the opening side of the press contact groove 12. The blade 1
In forming the layers 3 and 13, as in the case of FIG.
What is necessary is just to add a crushing process etc. in the press process of the press-contact groove 12, and to do so.

[0012]

As is apparent from the above description, the following excellent effects can be obtained by the press contact of the electrical connector of the present invention. First, since the blade for cutting the outer skin is provided on the press-fitting end side of the press-contact groove of the contact, when the wire or cable with the outer skin is pressed into this press-contact groove as it is, the outer skin is easily formed by this blade. It can be easily pressed even if the outer skin is thick or the outer skin has a high resin strength. Also,
At this time, the force of press-fitting may be small due to the presence of the blade portion, and there is an advantage that workability can be improved, and at the same time, problems such as poor contact due to incomplete tearing of the outer skin are greatly reduced. Furthermore, the presence of the blade allows the thickness of the metal plate of the contact to remain thick or even thicker, so that a sufficient contact area with the conductor portion of the electric wire / cable can be secured, and a large current capacity (conductivity) can be obtained. There is also the advantage that it can be obtained. Of course, if the tapered outer skin guiding portions are provided on the left and right sides on the opening side of the press contact groove, smooth guiding of the outer skin can be obtained, and better workability can be secured.
