Wire connection and tool and method for making it.

The invention relates to a cable connection according to the preamble of claim 1 or 2. The conductor connection includes a conductor connector that provides a galvanic connection between the connector and the flat metal strip conductors surrounded by an insulating jacket. Such a conductor connection is used for supplying or withdrawing electricity from a conductor or for connecting a conductor between a conductor for branching or extending a conductor.

The invention also relates to a tool and a method for making a wire joint.

DE-B-25 07 130, CH-A-662 906, and DE-A-24 09 311 disclose wiring connections having connectors that provide galvanic connections between terminals 15 and flat cable conductors. There are shown screw screw pins which pierce the insulating shell but do not penetrate conductors in the form of circular conductor wires. US-A-4 259 778 discloses a tool for optionally connecting single conductors of a multi-conductor flat cable. The tool first pierces the holes in the conductors and then connects them using the clamp-20 connectors placed in the holes.

The conductor connector according to the invention is intended to be used to form a galvanic connection between flat metal strip conductors 2 enclosed by an insulating shell 11 and electrical actuators such as a signaling lamp 12. This type of connector is shown in Figures 1 and 2. Alternatively, the connector: ·. is used to form a galvanic connection between the metal strip conductors 2 on two different wires 1 and 1a ", 30.

The connector may include the smart part described below, or may be without it.

In the case shown, the conductors 2 of the lead 1 are connected to the + and - poles 5 of the power supply and the lead 2 'acts as a code conductor from which the ON / OFF switching of the lamp 12 or other actuator takes place. Of course, code and current can also run on the same conductor, without the need for a separate code conductor. Power is supplied from the conductors 2 to the terminal via the conductor strips 4. The second conductor strip 4 is connected via a semiconductor switch 8s via a second terminal 13 of the lamp 12 to a second terminal 13 '. The electronic part 8 has the necessary circuit elements for controlling the power through the lamp 12. In addition, the electronic part 8 provides the switch 8s with an ON / OFF control whenever it detects the current. an identification code for the connector 3 obtained from the code conductor 2 ', which may also be a power conductor. The code conductor 2 'is connected to the electronic part 8 via a plurality of parallel-connected terminal strips 6. The conductor strips 6 may optionally be cut along line 7a. Depending on which conductor strips 6 are cut off, for example, the same or only different wattage signaling lamps 12 are made to function differently for a particular purpose, e.g., flashing, brake light, parking light, reversing light, etc. By cutting the strips 6 · · * 4 ·! . thus, the coding to be performed is consistent with the 12 locations of each lamp and its corresponding use. This coding can be accomplished, for example, by "nailing" a k sharp-pointed tool. For this nailing, the necessary holes 7 or * »· are made in the upper housing part 3a (Fig. 2) of the connector housing. 1: ·. 25 equipped with sharp-pointed pins for these holes.

The fitted pins may be movable so that any pins can be moved to or from the cut-off position according to the desired coding. With this tool, similar conductor connectors 3 can also be modified for their intended use.

Instead of interruptible coding strips 6, relays or switches may be used, some of which may be activated or deactivated in advance so that the code can pass only through a portion of the parallel connected relays or switches.

It is essential for the operation and reliability of such a connector to ensure an undisturbed and long-lasting galvanic contact between the conductors 2, 2 'and the conductor strips 4, 6. To this end, special connector pins 9 are attached to the conductive strips 4 and 5, the tips of which are sharpened such that the plastic shell 11 and conductors 2 of the conductor 1 can be pierced while the housing member 3a of the housing 10 to which said connector strips 4, 5,6 are press into place against the lower housing half 3b. The housing halves 3a and 3b may adhere to one another by means of, for example, self-locking snap connections.

Alternatively, a special tool (Fig. 5) may be used, which has puncture pins 9a similar to butters 9 but slightly smaller in diameter, for making pre-holes in the conductors 2. In this case, the tips of the pins 9 need not be sharpened for punching. The tool may be machine or manual. In the example of Figure 5, the pre-hole tool 25 is secured to a handle 21 that can pivot about the joint 22. The punching tool table 23 has guides 20 24 for receiving wire 1. By pushing the handle 21 down, lv is obtained. pre-holes in the timing 2 so that the connection of the cable can be done with a smaller power

This creates a contact between the pins 9 and the conductor 2 with a large surface area and continuous bias For a more even lip, the length of the blade ridge 10 is slightly smaller than the diameter of the pin 9 10 (9a) .If the pre-holes are made with the sharpened pins 9a of the tool, a corresponding design is obtained at the edges of the 9 with a slightly larger diameter than the elasticity of the dielectric material which clamps the edges of the hole 2 of the conductor around the pin 9. Since the tool pin 9a corresponds to the pin 9 shown in Fig. 3, it has not been specifically described. It may be advantageous for the pin 9 or 9a not to penetrate the insulating shell on the other side of the conductor, thereby providing less sealable points in the joint.

When the housing halves (corresponding to housing halves 3a and 3b) are pressed against each other, the pins 9 are pierced by the flat conductors 2 and 2 ', whereby a permanent contact is formed between the conductors 1 and 1a. Thus, in this embodiment, there is no electronic part included in the connector 3 ', nor an internal part! 1 and 2 as in the embodiment of FIGS. However, it is also possible to build the intelligent part in a connector for use in wire junctions as shown in FIG. 4A with reference numeral 18.
