Description

The The invention relates to an electrical connector for electrical Connecting a first line to a second line.

at currently on the market, in particular the automotive electrics market and known systems of so-called tapping connectors or quick connectors two cables to be connected to each other are placed side by side or one above the other. They are connected by severing or stripping and by connecting the joint by means of solder joint or by means of connectors or clamps together. This can be made at any point of the line, so that the subsequent Connecting consumers or controls to existing systems possible is.

• • durchgeschnitten, abisoliert und neu verlötet werden;
• • abisoliert und verlötet werden;
• • durchgeschnitten, abisoliert und mit Schraub- oder Klemmverbinden angeschlossen werden;
• • mit Klemverbindern durch die Isolierung angeklemmt werden oder
• • mit Schneidverbindern durch die Isolierung angeklemmt werden.

In known systems on the market, the two cables which form a first and a second line to be connected to it must either

• • cut through, stripped and re-soldered;
• • stripped and soldered;
• • cut through, stripped and connected with screwed or clamped connections;
• • be clamped through the insulation with clamp connectors or
• • be clamped through the insulation with cutting connectors.

In all the above cases while the insulation is interrupted. This is the condition Ingress of moisture possible. The adverse effect This affects the electrical connection and thus on the entire connected system.

One Another disadvantage is that the cross sections of the cables and the individual strands changed when cutting and be restructured in their structure. In solder joints exists, especially in vibationsgefährdeten Areas, the risk of subsequent cable breakage due to hardening of the solder joint. This is also the case with connections through terminals. By the Shut down The clamps will usually be a hard material of the clamp on the Press relatively soft material of the cable, being at the trailing edge the connection is also the risk of cable breakage.

One Another disadvantage may be that the introduction of known connector in cables in tight spaces or in harnesses in the composite often with difficulty is connected if the cables are not tightened in length can, and the connections not retracted in the connector or when mounting not under Train can be held.

at solder connections or in connectors requiring thermal treatment when used in bottlenecks or in areas of heat-sensitive substrates a clean processing for A good electrical connection is required, at least very much difficult. Surrounding parts are also claimed thermally, damage are often only elevated by To avoid the expense of insulation or shielding when heating.

at self-cutting clamp connectors can cause uncontrolled cutting the insulation and the contained line occur. by virtue of an inaccurate definition of cable cross sections in relation to Connector is often only a tangential incision present, the for establishing a proper current flow is insufficient. A too thick cable can be damaged massively with the consequence that electricity flows be hampered or cable breaks occur.

When Another disadvantage is the weight and size of the fasteners used considered. Through vibrations can therefore cable breaks be provoked. The size lets on bottlenecks, especially when needed by multiple terminals a connection point, problems arise, especially when in channels or behind tailor-made panels must be worked.

In 1 to 3 are three embodiments of a total with 10 designated electrical connector.

In all embodiments, the connector 10 a body in the form of a housing 12 by joining a first sub-element in the form of a lower part 14 and a second sub-element in the form of an upper part 16 is formed.

The top 16 and the lower part 14 are made of plastic in such a way that they pass through a flexible web 18 connected to each other foldable. The jetty 18 forms such a hinge 20 , At the footbridge 18 opposite side have the two sub-elements 14 . 16 mating parts of a locking connection 22 on. The figures show the assembled state in which the two sub-elements 14 and 16 under the bend of the bridge 18 are folded to each other, so that the locking connection 22 is engaged. As can be seen, the two sub-elements 14 . 16 on their mutually facing sides matching structures, so that they are to the housing 12 put together.

Both partial elements 14 . 16 each have half-structures for forming a first channel at their insides facing each other 24 for receiving a first line 26 and for forming a second channel 28 for receiving a second line 30 on.

At the front sides of the housing 12 are the mouths of the channels 28 . 30 as outlet openings 32 - 35 for the wires 26 . 30 designed.

Next, at least one of the two sub-elements 14 . 16 , here at least the lower part 14 , at least one reservoir in the form of a reservoir 38 on.

In a not yet assembled state of the two sub-elements 14 . 16 is the reservoir 38 filled with an electrically conductive adhesive in a flowable form and with a membrane 40 locked.

At least the two channels 24 . 28 form a cavity 42 in the case 12 , When joining the two sub-elements 14 . 16 becomes the membrane 40 of the storage container 38 broken up, leaving the electrically conductive adhesive in the cavity 42 pours and at least partially fills it. The adhesive is preferably pasty so that it can flow but not drip.

At the in 1 The first embodiment shown is the first channel 24 and the second channel 28 led crosswise. Next is next to the first reservoir 38 on the lower part 14 also on the top 16 a second reservoir is provided for forming a second reservoir for the electrically conductive adhesive and having a second membrane 46 locked. Every storage container 38 . 44 is at the other sub-element a thorn 48 . 49 associated with the folding of lower part 14 and top 16 the associated membrane 40 . 46 punctures.

After breaking up the reservoir 38 . 44 finds a mixing of the two components in the cavity 42 instead, after which the adhesive can then cure. At least one component can also be present as a free-flowing (and thus likewise free-flowing in the sense understood here) powder.

At the in 2 illustrated second embodiment, the first channel 24 and the second channel 26 guided parallel to each other and only in fluid communication. In an area where the two channels 24 . 28 open to each other is the reservoir 38 provided, which is filled with the electrically conductive adhesive and when joining the two sub-elements 14 . 16 breaks up and so does the fluid communication between the channels 24 . 28 completely filled out.

At the in 3 illustrated third embodiment, a similar configuration as in the second embodiment is made, but at the top 16 additionally a bridge contact element 50 made of metal, such as spring steel, is arranged. The bridge contact element 50 has in the area of both channels 24 . 26 one recess each 52 . 53 in which the two in the channels 24 . 28 guided lines 26 . 30 can be recorded contacting.

The outlet openings 32 - 35 are with sealing devices in the form of flexible lips 54 equipped.

The illustrated embodiments of electrical connectors 10 serve to a continuous first line 26 without cutting through the same, a second continuous line 30 safely electrically connected.

For this purpose, the procedure is basically such that a first section 56 the first line 26 - For example, a cable with inner strand - is stripped on a length that is shorter than the first channel 24 is. Also becomes a second section 58 the second line 30 (eg a comparable cable) stripped on a length shorter than the second channel 28 is. The first part 56 will then be in one of the two halves of the first channel 24 on one of the two subelements 14 . 16 placed so that the left and right of the first section 56 subsequent still isolated portions of the first line 26 in the first outlet 32 and the third exit port 34 to the existing there flexible lips 54 sealingly connects. Then the two subelements become 14 . 16 using the bridge 18 as a hinge 20 folded up and pressed together manually until the snap connection 22 locks.

At the in 1 The first embodiment shown here are the two sections 56 . 58 immediately pressed together, so that a direct electrical contact is formed. As the compression progresses, the two storage containers then break open 38 . 44 , z. B. by means of the respective mandrel 48 . 49 so that the contacting sections 56 . 58 Enveloped by the adhesive, which are then cured by contact with air or - when used as a two-component adhesive - by mixing the two components. In the case that first by the compression of the two parts 56 . 58 a secure electrical contact is made before the adhesive masses the two cuts 56 . 58 the adhesive does not necessarily have to be electrically conductive. After curing of the adhesive then the two sections 56 . 58 mechanically by means of the adhesive and the housing 12 over the locking connection 22 firmly connected. The housing 12 also acts as insulation of the stripped pieces 56 . 58 as well as protection for them against environmental influences. The flexible lips 54 serve on the one hand, the leakage of the adhesive from the housing 12 on the other hand, the penetration of undesirable substances such as moisture in the interior of the housing 12 to avoid.

At the in 2 illustrated second embodiment are the channels 24 . 26 Guided so that the two sections 56 . 58 do not touch. Here, the electrical connection is made exclusively by the electrically conductive adhesive from the reservoir 38 produced when folding the lower part and upper part and the resulting and the two sections 1 and 2 applied pressure bursts, so that the contained electrically conductive adhesive is pressed out and the cavity 42 filled. Due to the air inlet, the electrically conductive adhesive then hardens, so that a secure electrical and mechanical connection is made here as well.

At the in 3 illustrated third embodiment is additionally an indirect electrical contact between the two in the recesses 52 and 53 recorded sections 56 and 58 produced.

In a modification of this third embodiment, the edges of the recesses 52 and 53 formed as a knife edge, wherein the recesses 52 and 53 are equipped with a smaller inner diameter than the inner wires or strands of the two lines 26 . 30 , In the case, the two cuts must 56 . 58 before inserting into the channels 24 . 28 not necessarily stripped. When compressing the two sub-elements 14 . 16 cut the walls of the recesses 52 . 53 in the insulation and in the wires of the wires 26 . 30 and so put over the bridge contact element 50 an indirect electrical contact ago. The one of the walls of the recesses 52 . 53 sliced part is taken through these walls, so that this cutting has no negative impact on the wire cross-section. In this relative position become the cuts 56 . 58 with the bridge contact element 50 and the two subelements 14 . 16 over the metallically conductive adhesive from the reservoir 38 fixed.
