Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for reinforcing a pressure contact terminal which can effectively reinforce a beam having a slot pressed against an electric wire.

[0002]

2. Description of the Related Art In recent years, for example, in automobiles, there has been a trend toward higher functions such as a navigation system, and accordingly, the diameter of a wire harness, which is an electric wiring body in the vehicle, has been increased, and productivity has been reduced. .

Further, in order to improve the livability, the wiring space for the wiring harness in the vehicle has been reduced.

[0004] As the wiring of the wire harness into the vehicle becomes more difficult every year, there is a demand for a reduction in the diameter of the wire harness and a reduction in the size of the connector including the connection terminal.

[0005] To reduce the size of the electric wires constituting the wire harness and to reduce the size of the connection terminals, especially the crimp terminals, studies have been made to reduce the size of the crimp terminals. Instead, simply reducing the size does not improve productivity.

[0006] For this reason, studies have been made to use a press contact terminal capable of collectively connecting multiple poles, instead of a crimp terminal.
In order to reduce the size of the insulation displacement terminal, the thickness of the terminal material (conductive metal plate) of the insulation displacement terminal is reduced.

As shown in FIG. 2B, the press contact terminal 2 is formed by punching a conductive metal plate into a predetermined developed shape by a press or the like, and then bending the conductive metal plate into a substantially U-shape along the valley fold lines a and b. , FIG. 2
As shown in (A), the bottom wall 2c and both side walls 2a, 2a
b, and the electric wire 3 is provided on one of the side walls 2a.
(See FIG. 2 (C).) A pair of beams 2e, 2e having slots 2d, 2d pressed into contact with each other are formed by cutting, and the pair of beams 2e, 2e are arranged above the bottom wall 2c in the longitudinal direction. Are bent along the valley fold lines c and d so as to face in a direction perpendicular to.

[0008] Each beam 2e, 2e of the press contact terminal 2 is
The bent ends 2h, 2h are respectively connected to the uncut wall 2g in the cut 2f of the one side wall 2a, and the bent free ends 2i, 2i are cut into the notch 2j of the other side wall 2b.
It is designed to get inside.

[0009]

However, since the thickness of the conductive metal plate is reduced in the press-connecting terminal 2 in order to reduce the size, as shown in FIG. Is pressed against the slots 2d, 2d, and the uncut wall 2g
Ends 2 of beams 2e, 2e reinforced with
Although h and 2h are relatively hard to be deformed, the bending free ends 2i and 2i without reinforcement are greatly deformed outward and spread (see arrow e), and there is a possibility that the pressure welding of the electric wire 3 may occur. This deformation is likely to occur when handling and transporting the press contact terminal.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a reinforcing structure of a press contact terminal capable of effectively reinforcing a beam having a slot press-contacting an electric wire.

[0011]

According to a first aspect of the present invention, there is provided a press contact terminal having a beam having a slot for press-contacting an electric wire at a bent portion of a conductive metal plate. The present invention also provides a pressure contact terminal reinforcing structure in which a reinforcing portion of a projected ridge is formed at an appropriate position of the beam.

According to the first aspect, since the reinforcing portion is formed at an appropriate position of the beam of the press contact terminal, the beam intensity is improved even if the thickness of the terminal material is small, and the beam is deformed outward. It becomes difficult to do.

According to the second aspect, the conductive metal plate is substantially U-shaped.
The bottom wall and both side walls are formed by bending in the shape of a letter, and a pair of beams having slots for pressing against the electric wire are cut and formed in one of the side walls, and the pair of beams are formed into the bottom wall. A press-connecting terminal bent above the portion so as to face in a direction perpendicular to the length direction, wherein reinforcing portions of the projecting ridges are formed at appropriate positions of the pair of beams, respectively. Provides structure.

According to the second aspect, even a pair of beams formed on one side wall of the press contact terminal can be reinforced by the reinforcing portions. The beam may be formed by forming one or more pairs on one of the side walls.

According to a third aspect of the present invention, the reinforcing portion of the projecting ridge can be formed in a substantially U shape along the slot.

[0016]

Embodiments of the present invention will be described below in detail with reference to the drawings.

The parts having the same structure and operation as those of the prior art shown in FIG. 2 are denoted by the same reference numerals, and detailed description is omitted.

As shown in FIG. 1, the press contact terminal 2C has basically the same shape as the prior art press contact terminal 2 shown in FIG. 2, and as shown in FIG. , 2
Reinforcing portions 2k, 2k of embossing ridges extending in the vertical direction are formed on both sides of the slots 2d, 2d of e.

When the reinforcing portions 2k, 2k are formed on the beams 2e, 2e of the press contact terminal 2C as in the above reinforcing structure, the beams 2e, 2k are formed even if the conductive metal plate as the terminal material is thin.
e, the beams 2e, 2e are less likely to be deformed outwardly, so that the thickness of the terminal material of the press contact terminal 2C can be reduced, and the compact press contact terminal having excellent productivity. 2C is obtained, and accordingly, the connector can be downsized, and the diameter of the wire harness can be reduced, so that the weight can be reduced.

As shown in FIG. 2 (C), the reinforcing portion 2k may be a ridge-shaped reinforcing portion 2k projecting substantially in a U shape along the slot 2d of the beam 2e.

In the above embodiment, the pair of beams 2e, 2e formed on one side wall 2a of the press contact terminal 2C is reinforced by the reinforcing portions 2k, 2k, respectively.
The beam 2e may be formed by forming one or more pairs on one of the side walls 2a and 2b.

As is clear from the above description, the reinforcing structure of the press contact terminal according to the first aspect of the present invention is such that the reinforcing portion is formed at an appropriate position of the beam of the press contact terminal. Even if the thickness is thin, the strength of the beam is improved and the beam is less likely to deform outward, so it is possible to reduce the thickness of the terminal material of the pressure contact terminal, which is compact and has excellent productivity. Terminals are obtained, and accordingly, the connector can be downsized. In addition, the diameter of the wire harness can be reduced, and the weight can be reduced.

In the reinforcing structure of the pressure contact terminal according to the second aspect of the present invention, even a pair of beams formed on one side wall of the pressure contact terminal can be reinforced by the reinforcing portions.

Incidentally, the reinforcing portion of the embossed ridge may be substantially U-shaped along the slot.
