Definitions
- the object of the present invention is to provide a contact element of the type mentioned at the outset, which is the one just illustrated
- the object is achieved by a contact element of the type mentioned at the outset, the deformations being grooves or ribs running obliquely to the longitudinal axis of the conductor.
- each web between the grooves or each rib on the inner surface of the crimping section leaves a helical groove on the wire during crimping.
- the cross section of the wire is weakened to the same extent in every longitudinal position that comes to lie in the crimping section, to a much lesser extent compared to the weakening by the annular groove of the prior art.
- the contact area between the contact element and wire is much larger than in the prior art.
- This contact area can also be increased further by increasing the number of grooves or ribs compared to the prior art, and nevertheless has a lower risk of breakage than in the previously known crimp connections between the correcting element and the conductor.
- With an increase in the contact area the electrical conductivity, the thermal conductivity and also the mechanical hold improve.
- the weakening of the conductor is best distributed if the grooves or ribs are arranged obliquely or helically and parallel to one another.
- a very advantageous use of the contact element according to the invention is the use for insulated wires, in particular enamelled wires, without prior stripping of the end to be connected.
- the insulating layer or the lacquer layer also becomes an existing corrosion layer by cutting in the sharp-edged line elevations or by penetrating the tips of diamond-shaped er ⁇ Lifts in the wires scraped or pushed away and a good contact between the wire and contact element is ensured.
- the stripping process can be omitted.
- the scraped-off material Due to the helically running grooves in the crimped state, the scraped-off material is transported outward during crimping like a drill and seals the connection between the crimping section and wire at the edge of the crimping section and thus protects against the penetration of corrosive gases or liquids.
- FIG. 1 shows a contact element according to the prior art before crimping.
- 2 shows as a detail a cross section through the Ct Cp section with the wire lying therein after (_rimping and
- FIG. 3 shows the cross section of the wire at the height of the section III-III in FIG. 2.
- FIG. 4 shows a 5 shows as a detail a cross section through the cimpimping section of the contact element according to the invention with the wire lying therein after crimping
- FIG. 6 shows the cross section of the wire at the height of the section VT- VI in FIG. 5.
- FIG. 1 shows a contact element according to the prior art before crimping.
- 2 shows as a detail a cross section through the Ct Cp section with the wire lying therein after (_rimping and
- FIG. 3 shows the cross section of the wire at the height of the section III-III in FIG. 2.
- FIG. 4 shows a 5 shows as a detail a cross section through the cimpimping section of the contact
- FIG. 7 shows a roll-out view of the embodiment of the tir ⁇ edosdhriittes of the contact element according to the invention with a group of parallel grooves
- FIG. 8 shows a side view of the crimping section from FIG. 7 after crimping, dashed lines the course of one of the grooves is shown inside the crimp section.
- FIG. 9 shows another embodiment of the crimp section according to the invention in a roll-up representation with a group of parallel grooves and a second group of parallel counter-grooves which run obliquely to the grooves of the first group.
- 10 shows a side view of the crimping section according to FIG. 9 after crimping, the course of one of the grooves and one of the counter-grooves in the interior of the crimping section being shown in dashed lines.
- 11 and 12 represent further possible discharges which are made possible or manufactured by simply stamping in or rolling in or pressing in from the rear side.
- a contact element according to the prior art is shown before crimping with a conductor 27.
- the contact element has at one end a plug connection part 25 which can be pushed onto a flat contact plate in order to wire a device or part of a system.
- a clip portion 26 is provided, which has on its inner surface depressions in the form of grooves 33 which extend normal to the longitudinal axis 34 of the conductor.
- the conductor 27 can be a single, solid wire or a stranded wire and is pushed into the crimp section 26 in the direction of the arrow 28.
- Grooves 2 are provided on the inside of tt_jpab_x_hnittes 6, which, according to the invention, run obliquely to the axis 14 of the conductor 1. If the conductor 1 is now pushed into the crimping section 6 in the direction of the arrow 8 and the side walls 9, 10 of the crimping section 6 are bent in accordance with the arrows 11, 12, the webs 15 form between the grooves 2 on the surface of the Conductor 1 helical grooves 16, since the material of the conductor 1 is pressed into the grooves 2 by the pressure which is applied during crimping and is displaced by the webs 15 between the grooves 2.
- any insulation or corrosion layers located on the surface of the conductor are scraped off in some areas by the deformation of the conductor during crimping, so that there is good electrical and heat-conducting contact between the conductor 1 and the contact element.
- the scraped-off insulation material or the corrosion product is pressed outwards in the helical grooves 16 and seals the contact area between conductors 1 and 6 of the contact element against the ingress of corrosive gases and liquids.
- 5 shows the oblique course of the grooves 16 on the surface of the conductor 1.
- the cross section of the conductor 1 shown in FIG. 6 is significantly less weakened than in the prior art the cross section of the conductor (FIG. 3 ) in the area of an annular groove.
- FIGS. 7 to 10 show two embodiments for a crimp section according to the invention.
- a plurality of grooves 43 running parallel to one another are provided on the inner surface of the crimp section 46.
- the grooves 43 run obliquely to (Arrow 48) and thus to the longitudinal axis of the conductor. Between the grooves 43 are webs 45, which leave helical grooves on the conductor during crimping.
- 8 shows the crimp section 46 after crimping in a side view. - 1 -
- the inner surface of the crimp section 56 has a group of grooves 53 and a second group of counter grooves 54.
- the grooves 53 and the counter grooves 54 each run parallel to one another and both the grooves 53 and the counter grooves 54 run obliquely to the direction of insertion (arrow 58) and thus to the longitudinal axis of the conductor.
- grooves 53 and counter-grooves 54 form acute and obtuse angles with one another, so that they delimit diamond-shaped elevations 55, which also produce diamond-shaped depressions during crimping in the conductor. For reasons of strength, angles that are not in the range of 90 ° between the grooves 53 and counter grooves 54 are preferred.
- 10 shows a side view of the crimped crimp section 56.
- a dashed line 53 shows a groove 53 and a counter groove 54, which run inside the crimp section in a helical shape.
- ribs 65 are provided by embossing obliquely to the longitudinal axis or insertion direction 68 of the conductor.
- embossments in the form of diamond-shaped pyramids 75 are provided by means of embossing, with which the insulation density can be very easily penetrated by very high surface pressure.
- the elevations 75 are delimited by grooves 73, 74 which run obliquely to one another and obliquely to the direction of insertion 78, the grooves 73, 74 being embodied at the same level as the edge 79 of the section.
