A method for producing a permanent connection between an electrical plug connector (1; 21) and a multi-wire conductor (6; 6'; 24), wherein the plug connector (1; 21) comprises a detachable plug portion (2; 22) and a contact portion (3; 23), the contact portion being connected by a pinched connection to a portion of the multi-wire conductor (6; 6'; 24) via at least one pair of tongues (7, 8; 25) surrounding the conductor (6; 6'; 24) and having at least one opening (9, 10; 27) arranged between the tabs (7, 8; 25) for access to the conductor (6; 6'; 24), the contact portion extending either transversly to the longitudinal axis (x-x) of the plug connector (1) or in the direction of the longitudinal axis (x"-x") of the plug connector (21), characterised in that in addition to the pinched connection, the tongues (7, 8; 25) of the contact portion (3; 23) are connected to the conductor (6; 6'; 24) by solder (11, 11', 28), a piece of soldering wire (11; 28) being held between the pair or pairs of tongues (7, 8; 25), that the pair or pairs of tongues (7, 8; 25) is/are curved around the conductor (6; 24) in order to produce a pinched connection, and that the plug connector (1; 21) and/or the conductor (6; 24) is/are heated in the contact portion (3; 23).
Description
The invention relates to a method of making a permanent connection between an electrical plug connector and a multiple-wire conductor.
Such plug connectors find application in the wiring of electrical and electronic equipment and installations, in particular also in household appliances and automobiles. Two demands in particular are made upon the connection between the plug connector and the wire:
Firstly, the contact resistance should be constantly low. Secondly, the point of connection should be capable of withstanding high tensile stress.
It is known to solder or weld an electrical plug connector to the wire, or to press it onto this (attach it) by means of crimping. A device has also already become known by means of which the connection is made by a combination of welding and crimping. See published German Patent Application No. DE-OS 27 22 552. As a rule, however, a welded connection can only be achieved when two similar metals are to be joined, and the cost in respect of tools is considerable. Finally, it is known to attach tinned stranded wire cables to a contact part.
It is an object of the invention to provide a method of making a connection between a plug connector and a multi-wire conductor in which the advantages
- 2 5 3-153 of soldering and crimping are combined together.
According to the invention, there is provided a method of making a permanent connection between an electrical plug connector and a multi-wire conductor, wherein the plug connector comprises a detachable plug portion and a contact portion, the contact portion is connected by a pinched connection to a portion of the multi-wire conductor by means of at least one pair of tongues, said tongues surrounding the conductor and having at least one opening for access to the conductor disposed between the tongues, said opening either extending transversely to the longitudinal axis of the plug connector or extending in the direction of the longitudinal axis of the plug connector, and the tongues of the contact portion are also connected to the conductor by solder, the method comprising holding a piece of soldering wire between the pair or pairs of tongues, bending the pair or pairs of tongues around the conductor to produce the pinched connection, and heating the plug connector and/or the conductor in the region of the contact portion.
Another method of making a permanent electrical connection between an electrical plug connector of the foregoing kind and a multi-wire conductor comprises making the pinched connection of the contact portion to the conductor and then dropping heated liquid solder onto the conductor through said at least one opening in the contact portion.
The connections according to the invention show very low electrical contact resistances and are capable of withstanding high tensile stresses. The danger of corrosion is slight and the two method techniques, crimping and soldering, can be well combined with the apparatus here employed. In particular, the creeping of solder as far as the receptacle or the like and the consequent impariment of the plug connection is avoided.
In the drawings, two embodiments of plug connectors are illustrated, which are joined to a stranded conductor by two possible methods according to the invention.
Figure 1 shows a first electrical plug connector, in the connection region of which a piece of soldering wire is clamped.
- 3 5 3 4 5 2
Figure 2 shows the electrical plug connector according to Figure 1, whose connection region is heated with an electricalresistance soldering device, after it has been attached to an end portion of a stranded wire cable together with the piece of soldering wire.
Figure 3 shows the plug connector according to Figure 1, which however, has firstly been attached to an end portion of a stranded wire cable without soldering wire, a piece of soldering wire being now brouqht to melting by electrical inductance, so that molten solder penetrates into the connection reqion.
Figure 4 shows a second plug connector, in which a stranded wire cable is to be attached at right angles to its longitudinal axis and in the connection region of which a piece of soldering wire is clamped.
Figure 5 shows the use of a soldering device in the case of the second 15 plug connector, corresponding to Figure 2.
Figure 6 shows the view A in Figure 4, that is, the view onto the connection region of the second plug connector, with a clamped-in piece of soldering wire.
The plug connector 1, is in the embodiment,stamped or plug socket 2, 3 receptacle / having a crimp clawybf sheet metal, serves for connection to a bared end section 4 of out and bent as a
The crimp claw 3 or multi-wire a stranded Conductor provided with insulation 5. The crimp claw 3 has two pairs of ears between each of which a space,9 and 10, is provided.
Here, the longitudinal axis of the crimp claw 3 coincides with the or socket longitudinal axis of the receptacle/2. This axis is designated by the letters x-x. That this does not always have to be the case is described, for example, in association with Figures 4 to 6. The spaces 9 and 10 extend approximately at right angles to the longitudinal axis x-x; another arrangement, for example, at an angle of 45θ, is also
- 4 53452 possible. A piece of soldering wire 11 is clamped in the spaces 9 and
.
The end section 4 of the stranded conductor 6 is now placed into the crimp claw 3 and, together with the piece of soldering wire 11, is crimped (attached), by deformation of the crimp claw 3, onto the plug connector 1. The result can be perceived in Fiqure 2. The ends of the piece of soldering wire 11 extend out of the spaces 9 and 10; they are here about 5 mm long.
Then the crimp claw 3 is brought between two electrodes 12 and 13.
The lower bridge part 3a of the crimp claw 3 thereby lies on the electrode 12,while the electrode 13 presses directly on section 4 of the stranded conductor 6, between the pairs of ears 7 and 8, across the region of the spaces 9 and 10. The soldering wire 11 melts as a result of the electrical resistance heating of the region between the electrodes 12 and 13. There is a kind of capillary effect to be perceived: The ends of the piece of soldering wire 11 are sucked into the section 4 of the stranded wire cable and there fill up the interstices of the stranded wire cable 6. The result is a homogeneous connection between the stranded wire cable 6 and the crimp claw 3.
In Figure 3, the same plug connector 1 as in Figure 1 is illustrated. Here however, the crimp claw 3 was first attached to a stranded wire cable 6‘ without soldering wire. An end section of a soldering wire 11' is guided vertically from above in the direction of the section 4' of the stranded wire cable 6' which section lies freely, uninsulated, in the spaces 9 and 10 between the pairs of ears 7 and 8. Above the crimp claw 3 a coil 14 is disposed which heats the soldering wire 1Γ inductively, so that the solder falls in the form of drops through the spaces 9 and 10 onto the section 4' of the stranded wire cable 6'.
The solder thereby penetrates into the stranded wire cable 6' and fills up all the interstices present. The result is a homogeneous connection between the stranded wire cable 6' and the crimp claw 3.
- 5 or socket
In Figures 4 to 6, a plug connector 21 having a receptacle/22 is illustrated, in which the longitudinal axis x'-x' of the crimp claw 23 extends vertically to the axis x-x of the receptacle 22: in the case of another application, it could moreover, also extend at an angle of, for example, 45 or 60θ. The crimp claw 23 is for attaching onto an end section 24 of an insulated stranded wire cable. To or tongues this end a pair of ears/25 Sre disposed on the crimp claw 23, which pair of ears extends almost vertically to the axis x-x and to the axis x'-x1. The crimp claw 23 is bent somewhat in the direction of the receptacle 22 for the better rolling-up at the ends 26 of the pair of ears 25. A piece of soldering wire 28 is clamped in the space 27 between the pair of ears 25.
A bared end section 24 (or intermediate section) of a stranded conductor is now introduced into the crimp claw 23 and fixed to the plug connector 21, together with the piece of soldering wire 28, by rolling-up the ears 25. The result is to be perceived in Figure 5. One end of the soldering wire 28 extends out of the space 27 of the crimp claw 23. As already described in association with Figure 2, the soldered joint is now heated and the soldering wire 28 runs into the stranded wire cable 24. The result is a homogeneous connection between the stranded wire cable 24 and the crimp claw 23.
A further possibility for soldering the plug connector 21 has already been described in association with Figure 3: Molten solder is dripped into the space 27.
Two possible arrangements of the crimp claw, two possible methods and two forms of apparatus for these have been described in detail. However, these are certainly to be understood as advantageous, but also only as exemplary embodiments of the invention. So the opening can be formed not only as an open slit, but also, for example, as an oblong hole which, for example, is disposed in the bridge part 3a of the crimp claw 3. In this case the space is only shifted to the other side of the crimp claw 3.
