DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of arranging a cable on a cable alignment insulator,
The present invention belongs to the technical field of a press-connecting connector for connecting a cable conductor and a contact by pushing a bifurcated fork-shaped part of the contact so as to straddle the cable conductor.

[0002]

2. Description of the Related Art A conventional press-connecting connector of this type comprises a cable alignment insulator 1 as shown in FIG. 6 and a contact assembly in which a contact 5 is fixed to a base insulator 4 as shown in FIG. 6A is a top view, FIG. 6B is a front view, and FIG. 6C is a side view. A plurality of cable alignment grooves 2 are provided in the cable alignment insulator 1 in parallel to facilitate positioning of a cable to be connected. FIG. 6 shows a flat ribbon cable (FRC) for a flat ribbon cable (FRC) in which grooves having an arc-shaped cross section are arranged adjacent to each other. At the bottom of each groove, a contact groove 3 into which a contact slot is inserted is provided so as to be orthogonal to the direction of the cable alignment groove 2.

Next, FIGS. 7A and 7B are diagrams of a contact assembly, FIG. 7A is a front view, and FIG. 7B is a side view. The contact 5 is fixed to the base insulator 4 by embedding or fitting. The arrangement pitch of the contacts 5 matches the arrangement pitch of the contact grooves 3 of the cable alignment insulator 1. The contact 5 is provided with a U-slot 6 and has a forked fork shape. The tip and the inside of the U-slot 6 are slightly blade-shaped so as to easily pierce the insulating coating of the cable and advance.

The connection between the cable alignment insulator 1 and the cable by the contact assembly as described above is performed as shown in FIG. Since the cable alignment insulator 1 is for a flat ribbon cable (FRC), an example of connecting a flat ribbon cable is shown.
First, the flat ribbon cable 7 is arranged in the cable alignment groove 2 of the cable alignment insulator 1 so that the arc portion of the cable and the arc portion of the groove coincide with each other.
However, at the position of the contact groove 3 of the cable alignment insulator 1, the cable is pushed into the flat ribbon cable 7 so as to pierce it. When pushed forward, the U-slot 6 enters the contact groove 3 with the leading end of the U-slot 6 sandwiching the conductor 9. Since the width of the U-slot 6 is slightly smaller than the diameter of the conductor 9 of the cable, the conductor 9 advances by pushing the U-slot 6 open, so that sufficient contact is obtained.

[0005]

However, the fact that such a sufficient contact is obtained means that the U-slot 6
When this pushes, a large friction occurs with the conductor 9. Then, when the U-slot 6 is pushed forward, the conductor 9 is also dragged, and as a result, the conductor 9 is curved at the position of the contact groove 3 as shown in FIG. I will. The fact that the conductor 9 bends in this way means that the conductor 9 is located at a shallower position of the U-slot 6 than when it is not bent. The contact between the conductor 9 and the contact 5 is strong when the conductor 9 is deepest in the U-slot 6, and the contact force becomes weaker toward the end of the slot. Therefore, when the conductor 9 is curved as shown in FIG. 8B, there is a problem that the conductor 9 becomes shallower and the contact force becomes weaker.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, it is an object of the present invention to provide a cable alignment insulator 1 having a contact groove 3 which does not hinder the insertion of a U-slot and causes the conductor to be bent by the insertion. An object of the present invention is to provide a press-connecting connector capable of obtaining a sufficient contact between a conductor and a contact by providing a support member for preventing the contact.

[0007]

To achieve the above object, a press-connecting connector according to the present invention has the following configuration. That is, a first aspect of the press-connecting connector of the present invention is a contact for press-connecting a cable with a cable conductor sandwiched by a forked fork having a U-slot, a groove for aligning a cable, and a ; and a cable line insulator having a contact groove bifurcated forked portion of the contact disposed orthogonally is inserted, when the connection between the contact and the cable, thus placing the cables in the cable alignment groove, the cable conductor the by pushing the contact into the contact groove in a state straddling in bifurcated forked portion, the pressure contact connector to obtain electrical connection cable conductors and contacts, it is arranged
In under the cable, the cable longitudinal direction, the thin metal plate than the width of the thickness of the contact slot, the one side section
A press-connecting connector characterized by being provided in a cable aligning insulator perpendicular to a plate surface so as to bridge a contact groove and support a cable against pushing of a contact.

Secondly, in the first invention, the structure for fixing the metal plate to the cable aligning insulator is not completely fixed in the thickness direction of the metal plate but has a movable gap and prevents the metal plate from falling off. A press-connecting connector characterized in that a claw is provided and a claw locking recess is provided in the cable alignment insulator.

A third aspect of the present invention is the press-connecting connector according to the first or second aspect, wherein the metal plate supporting the cable is higher than the contact groove opening surface .

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment of the present invention, a metal plate may be formed by embedding a metal plate vertically at a position crossing a contact groove in advance when forming a cable alignment insulator with a synthetic resin, Further, when molding the cable alignment insulator, the metal plate may be formed with a groove having a width slightly smaller than the thickness of the metal plate, and the metal plate may be later pressed into the groove with a strong force. The metal plate provided as above is completely fixed without rattling, but by making the width of the groove larger than the thickness of the metal plate and providing a gap, the metal plate can move left and right by that much Also, there is an advantage that the metal plate can smoothly enter the U-slot even if the position of the cable alignment insulator and the U-slot is slightly shifted. In addition, by making the height of the metal plate higher than the bottom surface of the cable alignment groove, it is possible to compensate for the amount by which the insulating coating of the cable is pressed and compressed.

[0011]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a press-connecting connector according to the present invention. FIG. 1 is a view showing the structure of an embodiment of the press-connecting connector of the present invention. The metal plate 10 is provided so as to be orthogonal to the contact groove 3 of the cable alignment insulator 1, that is, to bridge the contact groove. (A) is a top view, (b) is a front view, and (c) is a side view. FIG. 2 is a perspective view.

As shown in FIG. 3, the metal plate 10 supports the cable even if the cable is placed in the cable alignment groove provided with the metal plate 10 and the U slot 6 is pushed in as shown in FIG. The extent to which the conductor 9 bends is smaller than in the case of (1). As a result, the contact state between the contact 5 and the conductor 9 becomes better than before. In the embodiment shown in FIGS. 1, 2 and 3, the metal plate 10 is completely fixed by embedding or press-fitting in the cable alignment insulator. Care must be taken so that the metal plate 10 is positioned exactly in the center of the U-slot 6 of the contact 5.

Therefore, even if there is a slight displacement, the metal plate 1 is inserted so that the metal plate 10 can enter the U slot 6 smoothly.
FIG. 4A shows a structure in which 0 can freely move to the left and right to some extent. The width of the groove in which the metal plate 10 is accommodated is slightly larger than the thickness of the metal plate 10 to provide a gap so that free movement is possible by the gap. On the other hand, since such a gap causes the metal plate 10 to jump out or fall off depending on the posture of the cable alignment insulator 1, a projection (lance) is formed on the metal plate as a retaining member.
11 is provided, and the metal plate 10 is pushed into the groove.
Are locked by the walls of the locking recesses 12 provided on the cable aligning insulator 1 side so as not to come off.
FIG. 4B is a perspective view of the metal plate 10 provided with the lance 11.

In the above description, the case where the upper end of the metal plate 10 coincides with the bottom surface of the cable alignment groove has been described. However, when the insulating coating of the cable is compressible, the U-slot is used. When 6 bites the conductor 9 and pushes forward,
Since the conductor 9 compresses the insulating coating, the conductor 9 is curved accordingly.

FIG. 5 is a perspective view of a structure in which the metal plate 10 protrudes higher than the bottom of the cable alignment groove in order to minimize such a curvature of the conductor 9. The structure in which the metal plate 10 is protruded in this manner can be used when the metal plate 10 is fixed as shown in FIGS. 1, 2 and 3 or when the metal plate is movable in the thickness direction as shown in FIG. Can also be applied.

[0016]

As described above, in the press-connecting connector of the present invention, the metal plate is provided so as to bridge the portion where the bottom of the cable alignment groove is interrupted due to the presence of the contact groove. When the U-slot is pushed in while the conductor of the cable is bitten, the conductor is not dragged and bent as in the conventional case, and there is an advantage that sufficient contact between the contact and the conductor can be obtained.
