Description

The present invention relates to a multipolar cable connector that can interconnect two multi-core electrical connectors. Furthermore, the invention relates to several components of this cable connector. The cable connector according to the invention is intended and suitable in particular for use in the automotive sector. For example, with the aid of this multipolar cable connector data can be transmitted to a monitor which is detachably connected to a component of an infotainment device in a motor vehicle, which is located on the rear wall of a motor vehicle seat. The multipolar cable connector is typically designed for the transmission of digital multimedia data.

Typical electrical cable connectors according to the prior art are designed as connectors whose connector parts are fixed in a frictional connection to each other after suitable alignment and arrangement by spring force and friction, but can be separated again if necessary. Plug parts include "male" parts with outwardly facing contact pins which are inserted into inwardly facing contact openings of "female" parts such as sockets or couplings.

The present invention draws on the developed in recent years compression spring technology or SLC technology (spring loaded contacts), according to - according to the circulating in the art statement "DOCK instead of PLUG" - a spring-loaded Tastverbindung between spring contact pins (spring loaded contacts) and the respective associated contact surfaces (contact pads) is generated on massive pins and used. In terms of their function, these solid pins serving as "contact pad" are hereinafter referred to as contact pad pins. Some of the components required in the context of the present invention for implementing the SLC technique, such as spring contact pins, spring contact pin strips, contact pad pins and contact pad pin headers, are commercially available and are available, for example, from PRECI-DIP SA, Rue Saint-Henri 11, CH-2800 Delemont, Switzerland ; In some cases, the commercially available components must be modified, processed and completed in accordance with the present invention.

The document US 2004/0 115 994 A1 shows with the 5 . 6 and 7 - according to the terminology used in these application documents - a spring contact pin header fitted with spring contact pins. The spring contact pins can be mounted in a predetermined arrangement within a block-shaped plastic housing. For electrical connection of the spring contact pins it is stated that a pin end (not shown) is provided for connecting a wire or circuit string by means of crimping, soldering or other known electrical connection measures.

The resulting spring contact pin header may form the connector interface in a portable device, such as a mobile phone, which is insertable into a base station in which a contact pad pin bar equipped with contact pad pins is located as a corresponding electrical detachable contact means. When inserting the device into its base station, tip-to-tip contacts are created between the spring-assisted pins on the spring contact pins and the contact pads of the contact pad pins.

The document GB 2 243 034 A relates to electrical connectors intended to provide a detachable electrical connection between an electrical device and another electrical device, or between an electrical device and a cable, or between a cable and another cable. The releasable electrical connection makes use of the SLC technique and creates touch connections between spring-loaded pins of spring contact pins on a spring contact pin header with contact pads of contact pad pins on a contact pad header. Preferably, the contact surfaces of the contact pad pins may be recessed relative to a front surface of the contact pad header to prevent unwanted contacts with foreign objects, such as coins. Such Kontaktpadstiftleiste can, for example, as a connector interface to a mobile phone this. Nothing is said about the electrical connection of the spring contact pins and / or the contact pad pins.

Spring contact pins are known in the art, and for example, the free encyclopedia WIKIPEDIA ^® (WIKIPEDIA ^® is a registered trademark of the Wikimedia Foundation, Inc., San Francisco, CA 94105, USA) under the heading "spring contact pin" described. Often the term POGO ^® pin is used (POGO ^® is a registered trademark of Everett Charles Technologies, or "ECT", Pomona, CA 91767, USA). Spring contact pins and plastic strips in which a number of spring contact pins are inserted at regular intervals and in a single-row or double-row arrangement are, for example, from the distribution centers of the above-mentioned ECT or are manufactured, for example, by PRECI-DIP SA, Rue Saint-Henry 11, CH-2800 Delemont, Switzerland or, for example, by Shenzen Tyco Hanconn Precision Electronics Co., Ltd. Shenzen City, Guangdong Province, China offered and distributed. PRECI-DIP SA also offers contact pad pins, which are referred to as "pad connectors", as well as strips fitted with such "pad connectors"; see. for example the product names 800-10-NNN-30-507101 and 802-10-NNN-30-507101. These are so-called SMD Pad Connectors, which have a smooth, flat bottom at the end opposite the contact surface, which should contact a planar soldering surface on a printed circuit board or circuit board with the aid of SMD technology. To the knowledge of the inventor named herein, no "pad connectors" are still provided which are integrally provided with a wire connecting means such as solder cup, crimp tube or fork with wiring slot at the pin end opposite to the contact surface. Such contact pad pins are needed in the context of the present invention for the electrically conductive connection with the stripped wire ends or wire ends of the multi-core electrical connector.

The 1A . 1B and 1C show a contact pad pin 10 , Essentially, this is a massive cylindrical body 12 electrically conductive metal, typically selected brass alloys, such as CuZn36Pb3, bronze / beryllium alloys, other copper alloys, nickel / tungsten alloys, nickel / chromium alloys, nickel / manganese alloys, selected stainless steels and other metallic metals Materials with excellent electrical conductivity. The body 12 may be plated with copper, nickel, cobalt, palladium, gold and alloys thereof. Frequently used is an at least 2 μm thick coating of nickel, on which there is a gold layer at least 0.5 μm thick. These coatings provide high corrosion resistance and a particularly low contact resistance. The massive cylindrical body 12 may typically have a diameter of 0.5 to 2.5 mm and a length of 4.0 to 12 mm; an exemplary, shown in the figures body 12 has a diameter of 1.50 mm and a length of 4.70 mm.

In these grooves 58 can easily contact pad pins 10 suitably inserted so that the stage 34 on the circumference of each contact pad pin 10 rests against a groove end. On the with contact pad pins 10 equipped positioning half 52 ' becomes the other matching positioning body half 52 '' applied, and both halves positioning 52 ' and 52 '' permanently become one with contact pad pins 10 fitted positioning body 50 united, in particular welded together. In support of this union can on both halves positioning 52 ' and 52 '' - Not shown - be formed integrally locking locking means. The contact surfaces 16 the contact pad pins used 10 aligned with a front surface 59 of the positioning body 50 perpendicular to the grooves 58 is aligned. As illustrated, at the distal ends of the one positioning body half 52 ' depending on a fastening aid be formed, namely ever a tab 76 ' . 76 '' , in each a hole 78 is omitted.

After in every hole 42 or in most holes 42 of the positioning body 40 one contactpad each 10 has been inserted, or after in each formed from the paired grooves bore on the positioning body 50 one contactpad each 10 has been used is at the protruding solder cup 22 each one end of a wire or a wire of the electrical connector soldered. This soldering can be done manually with the help of a soldering iron. This soldering is preferably carried out with the aid of a soldering machine. A first manipulator on the soldering machine grabs the contact pad pins 10 fitted positioning body 40 and dips the solder cups 22 into a wave bath of liquid solder. Subsequently, the first manipulator contacted the soldered with liquid solder solder cups 22 with a number of suitably arranged wire or wire ends which are suitably offered and kept ready by a second manipulator.

According to an alternative variant of the method, the positioning body 40 or the positioning body 50 with contact pad pins 10 be fitted to the solder cups 22 or others Wire connection means 24 or 28 already wire ends or wire ends of the electrical connector are connected. In the case of already soldered wire or wire ends, this process variant avoids the need for the positioning body 40 or the positioning body 50 must be exposed to the soldering conditions. There is a greater latitude for the selection of Positionierkörpermaterialien, since they do not have to withstand the soldering heat of about 260 ° C.

In the case of the other wire connecting means, the wire or wire ends are connected to the cable of the electrical connector in the usual way. In a crimp tube 24 a wire or wire end is inserted, and then pressed together. In the wiring slot 28 between the two pins 26 ' and 26 '' a wire or wire end is inserted and the whole assembly is compressed. The intermediate product obtained after that, namely the positioning body 40 or 50 that with contact pad pins 10 is fitted to the wire connecting means 22 . 24 or 28 each wire end or wire end of the electrical connector is mechanically stable and electrically connected, is introduced into the mold cavity of an injection molding machine and molded there under low pressure and low temperature conditions with selected potting compound. This overmolding is also referred to by those skilled in the art as "overmolding," and the typical, known overmolding conditions can be used. Typically, an injection pressure of less than 12 bar overpressure is used. The mold cavity housing and the injected melt typically have a temperature of 180 to 200 ° C. Casting compounds are selected which already have a sufficiently low viscosity under these conditions. Suitable casting compounds here are, for example, the known polyamide-based hotmelt molding compositions which can be processed under low-pressure conditions; belongs here to a known, commercially available product of this type about MACROMELT ^® (MACROMELT ^® is a registered trademark of Henkel AG & Co. KGaA, 40589 Dusseldorf DE). Other casting compounds which can be used here include polyethylene, polysulfides, low-melting ABS resins and other materials familiar to the person skilled in the art. The overmolding serves primarily to provide a protected arrangement for the wire joints, in which they are embedded in a body of potting compound. Furthermore, care is taken during encapsulation that the molten potting compound also contacts the cable insulation at the adjacent cable end of the electrical connector. The cable insulation dips into the molded body formed, and it is created an intimate connection between the molding and cable insulation, which provides a strain relief of the cable. Furthermore, the adjacent cable section may be given a certain spatial orientation with respect to the arrangement of the contact surfaces of the contact pad pins.

The product obtained thereafter is an exemplary, usable as part of a connector assembly provided according to the invention and with 4 illustrated Kontaktpadstiftleiste 60 ,

This exemplary contact pad header 60 has a plastic molded body 62 , the two essentially plate-shaped elements 64 and 68 has, which are integrally attached to plate main surfaces together. Each plate-shaped element 64 and 68 forms a substantially rectangular parallelepiped bounded by two spaced major surfaces as well as longer and shorter narrow side surfaces. On a molding back 70 two longer side surfaces of the two plate-shaped elements are aligned 64 and 68 together. From this molded body back 70 stands an integrally molded head 72 in which a cable end 4 of the first multi-core electric cable 2 empties.

In the plate-shaped element 64 are those, in the positioning body 40 or 50 held contact pad pins 10 embedded. The front surfaces 44 respectively. 59 the positioning body 40 or 50 and the contact surfaces aligned therewith 16 the contact pad pins 10 occur on a longer narrow side surface 66 from the plate-shaped element 64 out and aligned with this side surface 66 , The to the wire connection means of the contact pad pins 10 , in particular at their solder cups 22 , connected wire or wire ends unite in the protruding head 72 and enter the cable end there 4 one.

The cable end 4 is parallel and in the distance to the molding back 70 Guided and is in one with the plate-shaped elements 64 and 68 largely aligned in the head 72 introduced. It is obtained a slender arrangement in which the thickness or height of the molding 62 only slightly exceeds the cable diameter, typically less than 2 to 4 mm; the molded body 62 will often have a height or thickness less than 10 mm, for example a height or thickness of about 8 mm. The slender arrangement then obtained is well suited to be installed in a generally flat device, which has only a small depth, for example, a thickness or depth less than 20 mm.

The free main surface on the other plate-shaped element 68 forms a support surface 74 , In the direction of this bearing surface are on the plate-shaped element 68 one piece two tabs 76 ' and 76 '' formed, each of the opposing shorter narrow side surfaces of the plate-shaped element 68 protrude. In every tab 76 ' . 76 '' is ever a hole 78 educated; it will receive an "eye" through which a screw passed can be used with their help the Kontaktpadstiftleiste 60 can be attached to a support in a device. Instead of a, an "eye" forming hole 78 could be on every tab 76 ' . 76 '' a protruding pin (not shown) may be formed which may be inserted into an elastically deformable locking bore on the device about the contact pad header 60 to be fixed to a support in the device. Inside the plate-shaped element 68 can be formed by a border limited recesses to save material; that plate-shaped element 68 will then partially have a cage-like structure.

The 5A to 5C show an alternative contact pad pin 80 , To a soldering cup 82 closes a central, massive, cylindrical body 84 on which a Kopfabschitt 86 with a larger diameter follows. The transition from the middle body 84 to head section 86 is stepped, and the step or shoulder thus formed 88 forms a stop, the insertion of the contact pad pin 80 limited in a hole on the positioning. In this case, the insertion of the contact pad pin takes place 80 into the bore of "front", that is, from the front surface of the positioning ago ago, where first the solder cup 82 is introduced into the bore. When the step or shoulder 88 at the front end of the bore, the solder cup protrudes 82 beyond the rear end of the bore and is there for the soldering of a wire or wire end available. This alternative offers the advantage that the mechanical pressure exerted by the spring and the pin on a contacting spring contact pin on the contact surface on the contact pad 80 is exercised, the contact pad 80 can not drive out of the hole on the positioning, in which it is inserted.

The contact pad pin inserted into the hole on the positioning body 80 stands with the length of his head section 86 beyond the front surface on the positioning body; this length may typically be about 2 to 4 mm when the entire contact pad pin 80 has a typical length of about 10 to 13 mm. These protruding head sections 88 can be encompassed pressure-tight from the housing of the injection mold, so that in the subsequent encapsulation, the molten potting compound, the contact surface 90 at the head section 88 of the contact pad pin 80 can not reach and otherwise soil.

The end face of the head section 88 forms the contact surface 90 of the contact pad pin 80 , How out 5A can be seen, this contact surface is in the form of a reentrant or concave spherical partial surface, so that at this contact surface 90 a depression 92 is trained. The deepest point of the depression 92 may for example be about 2 to 3 mm from the circumference of the contact surface 90 be reset when the contact surface 90 For example, has a diameter of about 1.5 to 2.5 mm. Such a deepening 92 Increases the contact surface to a contacting pin on a spring contact pin and thus reduces the contact resistance between Kontaktpadstift 80 and one, this contacting spring contact pin.
