Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector for connecting an undercarpet cable.

[0002]

[Prior Art]

 Unlike the connection terminals and connectors used for general power wiring, the connector for connecting the undercarpet cable for electric power is often the so-called IDC type connector that directly connects to the conductor without peeling off the insulator. Has been done. An example of this type of connector is shown in FIGS. In FIG. 8, the connector 1 is a foldable connector that is formed of a good conductor metal and that has a bent portion 2. Further, a protrusion 3 for penetrating the insulator is formed on the inner surface thereof. The connector 1 having such a structure is used as shown in FIG.

That is, the connector 1 is attached to the under carpet cable 6 in which the flat conductor 4 is covered with the insulator 5 so as to sandwich the insulator 5. By applying a predetermined pressure from both upper and lower sides of the connector 1, the protrusions 3 provided on the inner surface pierce the insulator 5 and the conductors 4 and the protrusions 3 inside contact with each other, so that the electrical connection with the connector 1 is established. Done. Even if the protrusion 3 is a cylindrical protrusion 7 as shown in FIG. 10, the insulator 5 can be pierced as long as the protrusion 3 has a sharp peripheral edge 7a at its tip end. It can be used even if the tip is not needle-shaped.

[0004]

[Problems to be solved by the device]

 By the way, in the conventional connector 1 as described above, the projection 3 is merely bited into the insulator 5, and the coupling relationship between the both is maintained. Therefore, when the connector 1 is vibrated or a mechanical load is applied to the inner surface of the connector 1 toward the outside, the end 1a of the connector 1 is easily opened as shown in FIG. I will end up. By the way, the projection 3 of the connector 1 and the conductor 4 of the under carpet cable 6 are in contact with each other only by the pressing force at that time, as shown in FIG. Therefore, when a force is applied to open the end portion 1a of the connector 1 as described above, the contact force between the conductor 4 and the protrusion 3 is reduced, resulting in poor electrical connection.

Therefore, in order to solve the above problems, conventionally, as shown in FIG. 13, a gripping mechanism 10 including a claw 8 and a recess 9 for receiving the claw 8 is provided at an opening end of the connector 1. Is provided. In this connector 1, as shown in FIG. 14, after the projection 3 of the connector 1 is made to bite into the insulator 5, the gripping mechanism 10 blocks the outward opening of the end of the connector 1. However, in the case of the above, the structure of the connector 1 becomes complicated and a complicated mold is required at the time of manufacturing, so there is a problem to be solved that the cost of the connector 1 increases. The present invention has been made to solve each of the problems described above, and has a relatively simple structure, does not cause cost increase, and ensures reliable electrical and mechanical connection even when vibration or external force is applied. The purpose is to provide a flexible connector.

[0006]

[Means for Solving the Problems]

 The connector of the present invention has a pair of opposing rising blade molds, which penetrate the conductor in the undercarpet cable by the rising blade molds and flip up both ends of the conductor upward. Both ends of the side plate and the conductor that has been turned up together with the rising blade of the male side plate are inserted into the openings, and both ends of the conductor are wound on the surface by the end of the rising blade. It has a female side plate to be fixed.

[0007]

[Action]

 The connector of the present invention pierces the insulator of the undercarpet cable and the conductor inside by the rising blade type portion of the male side plate, and is inserted into the opening of the female side plate, and both ends of the conductor are formed on the surface of the female side plate. Start up, and fasten it by winding it with the edge of the blade. This provides a simple structure, low cost, and secure electrical and mechanical connection.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an outline of a connector 1 of the present invention. In the figure, 11 is a male side plate of the connector 10. The male side plate 11 is made of a metal having good conductivity and has a pair of standing blade type portions 12 arranged to face each other. The shape of the blade part 12 is arbitrary, and in addition to the rectangular shape as shown in the drawing, a rising blade part 13 having a triangular shape as shown in FIG. 2 or as shown in FIG. The raising blade type portion 14 may be used. The point is that the shape of the rising blade 12 and the like may be such that it can penetrate the insulator 5 of the undercarpet cable 6 and the conductor 4 inside. Reference numeral 15 is a female side plate that is combined with the male side plate 11 configured as described above. The female side plate 15 is formed with a pair of facing openings 16 through which the rising blade type portions 12 of the male side plate 11 are inserted.

Next, a method of using the connector 10 configured as described above will be described with reference to FIGS. 4 to 7. As shown in FIG. 4, the male side plate 11 is placed on the lower surface of the undercarpet cable 6 where the connector 10 should be connected. On the other hand, the female side plate 15 is placed on the upper surface of the undercarpet cable 6 so that the opening 16 is located at a position corresponding to the rising blade type portion 12 of the male side plate 11. Next, as shown in FIG. 5, the male side plate 11 is pressed from the lower side, and the insulator 5 and the conductor 4 of the under carpet cable 6 are pierced by the rising blade mold 12. As a result, both ends of the conductor 4 that has been pierced are turned up, and the leading end is inserted into the opening 16 of the female side plate 15 together with the rising blade mold 12.

Next, as shown in FIG. 6 and FIG. 7 in which the portion A of FIG. 6 is enlarged, the rising blade mold portions 12 inserted into the openings 16 are wound on each other on the female side plate 15 so as to be tightened. Bend inward. By doing so, the male side plate 11, the female side plate 15, and the conductor 15 of the undercarpet cable 6 are completely electrically connected to each other. Further, since both ends of the rising blade-shaped portion 12 of the male side plate 11 strongly press both ends of the conductor 4 that has been turned up to fasten it by winding, the mechanical connection strength becomes sufficient. In the above embodiment, the example in which the number of the undercarpet cables 6 is one has been described, but it is of course also applicable to the case where two undercarpet cables 6 are stacked and both are electrically connected to each other by the connector 10. The same effect as above can be obtained.

[0011]

[Effect of the device]

 As described above, according to the present invention, the rising blade type portion of the male side plate pierces the insulator of the undercarpet cable and the conductor inside, and is inserted into the opening of the female side plate, and the conductor is formed on the surface of the female side plate. Since both ends of the blade are fixed by winding by the edges of the rising blade type portion, the following effects can be obtained. (1) With a relatively simple structure, it is possible to maintain a complete electrical connection to the undercarpet cable and a sufficient mechanical connection strength. (2) Since both ends of the turned-up conductor in the undercarpet cable are fixed on the female side plate by winding and tightening with the rising blade type of the male side plate, the reliability of electrical contact is improved. high. (3) The work of connecting the connector to the under carpet cable is easy, and the improvement of workability can reduce the wiring cost of this type of cable.
