Description

The The invention relates to a pluggable connection device for connection a cable having at least one or more conductors, in particular round cable or flat cable, on insulation penetrating Contacts of a connection housing.

pluggable Connecting devices with plug-together male and female components are known in a variety of embodiments. Disadvantages are usually their relatively complicated construction and their relative complicated handling, especially in the area of so-called Heavy connector often also a packaging by specially trained specialist personnel.

The solution This problem is the object of the invention.

The Invention solves This object is achieved by the subject matter of claim 1, according to which Indicator a cable receptacle which can be plugged into the connection housing for receiving a free end of the cable to be connected and for insertion of the free end of the cable into the junction box with the insulation piercing Contacts are provided to the conductors of the cable receptacle inserted cable in the connector housing in their in the cable receptacle inserted state by means of an axial insertion of the cable holder into the connection housing and a preferably following the insertion subsequent rotation or pivoting movement the cable receptacle to contact directly relative to the connection housing.

Different as a plug of a connector has the cable receptacle no contacts except for possibly existing cable shield contacting means for contacting the preferably insulated conductor of the cable on.

The Cable receptacle rather serves only to the cable and thereby preferably prefabricated the individual conductors of the cable in such a way in the handling tool "pluggable Cable reception " and to center that secure contacting the individual Conductor of the cable with the insulation piercing contacts through an axial insertion in combination with a simple insertion movement and a preferably subsequent simple rotational movement is possible.

In order to Be the actual plug contacts between the plug and saved the socket part, which reduces the design effort.

moreover must be in Plug part no contacting of the conductors take place but only a simplified prefastening - z. B. by fanning and the assignment of marks - what can also be realized by less qualified personnel.

advantageous Variants of the invention are specified in the subclaims.

following The invention will be described with reference to the drawing based on embodiments explained in more detail, wherein also many other advantages and options of the invention clearly become. Show it:

1 - 3 various perspective views of a connecting device for cables to a connection housing;

4 - 21 a round cable for connection to the connection device and its connection to the connection device in successive steps;

22 - 36 various other views of the connection device and its components 1 to 3 ; and

37a -E perspective views of elements of another embodiment of the invention.

1a shows a perspective view of a connection device 1 for connecting a round cable 2 ,

A cable receptacle 3 serves to accommodate the individual, preferably insulated conductor 4 (please refer 4 ) of the stripped cable 2 and to prepare the cable 2 for connection to a contacting device with insulation-piercing contacts 5 and optionally for connecting a cable shield.

The connection devices 1 are not on the connection of round cables 2 but can also be used, for example, for connecting cables in elliptical or flat cable or the like, for which there is only a slight modification of the components "cable receptacle 3 "For receiving the round cable 2 requirement.

The connection device 1 to 1 to 3 serves to connect the cable 2 to an electrical system or an electronics - here only by a wall 6 indicated - Overhousing.

The cable receptacle 3 This is done in a connection housing 7 plugged in, after 1 at the Wall 6 is fixed.

It is advantageous that the cable receptacle 3 only for holding the isolated ladder 4 of the stripped cable 2 serves, but not for electrically contacting the conductor wires 4 whereas the connector housing 7 a - preferably multi-part - contacting device with insulation-penetrating contacts 5 for insulation-penetrating contacting of the electrical conductors 4 or conductor wires of the cable 2 by means of an axial insertion of the cable receptacle 3 into the connection housing 7 and a subsequent (or combined) rotary movement of the cable receptacle 3 in the connection housing 7 having.

In order to it is no longer necessary, as in the prior art, a full plug and a complete one To realize socket part, which is one of the two parts - for example the plug part - to Connecting the cable and for contacting the cable is used and the other connection part for contacting outgoing conductor and wherein the actual contact between the plug part and the female part by a nesting of plug and socket contacts realized on the male and female parts.

In the context of the invention, however, the cable to be connected is only pre-terminated stripped in the cable receptacle 3 fanned inserted, whereupon the actual contacting of the conductors with the insulation piercing contacts 7 in the counterpart of the connector, here in the connection housing 8th , he follows. It is also conceivable that instead of a cable directly individual conductors are inserted into the conductor holder.

With a simple modification of the connection housing as a clutch housing and not as a flange housing can these elements also as a coupling for connection to another cable be interpreted.

The connection housing 7 points next to the contacting device for contacting the conductor 4 of the cable 2 also further - largely arbitrarily ausgestaltbare outgoing contacts 8th which will be described in more detail below.

To 1 is the connection housing 7 as a flange housing with a flange 9 designed, in particular for mounting on a wall opening 10 ( 12 ) the Wall 6 a parent housing or the like. Is suitable. The flange may have holes to screw it to the wall or to receive screws by corresponding holes in a handle 28 are guided on the cable holder (not shown here, purely optional).

With the invention, in particular the relatively expensive according to the prior art connector parts on inexpensive cable receptacles 3 be reduced or saved.

A special savings potential results from the fact that the cable recordings 3 - To have any optional cable shield connection - no own metallic connection for electrical conductors or a contacting device for electrical conductors, since the plug contacts between the plug and the socket omitted.

In addition, a particular advantage of the concept results from the fact that the cable receptacles 3 can be designed so that even untrained personnel a connection of the cable can be made. It is only necessary to prefabricate the cable and then it in a suitable manner in the cable receptacles 3 appeal. The supernatant can easily be cut off.

It should be noted that the contacting device 5 is preferably designed in isolationsdurchdringender connection technology. Suitable, for example, cutting contacts with forked contacts or insulation piercing contacts.

Views of the connection housing 7 with the contacting device 8th are in 28 to 29 shown.

After that, the connection housing points 7 a - preferably except for contours such as flattening to prevent rotation in the correspondingly shaped wall opening substantially cylindrical - sleeve 11 on, at one end of the flange 9 is attached or molded. The sleeve 11 intersperses the wall breakthrough 10 , where the flange 9 on the wall 6 rests on ( 1 . 12 . 28 ).

Preferably, the outer circumference of the sleeve 11 with an external thread 12 ( 28 ) on which a mother 13 (please refer 3 or 35 ) is screwed, with which the connection housing 7 - if necessary using a sealing washer 17 between the flange 9 and the wall 6 - on the wall 6 is determined. The sealing disc facilitates in a simple way the formation of a high degree of protection.

On the inner circumference of the sleeve 11 is one or more radially inwardly extending contours such as an axial groove 14 or distributed. These contours may extend over part of the axial length of the sleeve 11 extend or over the entire axial length. You realize a kind of alignment help hiss the cable receptacle 3 and the connection box 7 ,

The IDC contacts 5 are on the inner circumference of the sleeve 11 arranged circumferentially distributed; their number corresponds to the number of conductors to be contacted 4 of the cable 2 ,

The insulation penetrating contacts 5 are according to a particularly preferred embodiment as the inner circumference of the sleeve 11 distributed, formed radially inwardly from the inner circumference of the sleeve projecting cutting forks, the opening of a Einführöff 15 have, wherein the insertion openings 15 the cutting forks are aligned in the same direction so that conductors tangentially or in the circumferential direction are inserted into it ( 29 ).

The cable receptacle 3 centered and holds the ladder 2 such that they after plugging in the cable receptacle 3 in the connection housing in the axial direction (plug-in direction X; 35 ) with a rotating movement in the circumferential direction U ( 29 ) into the insulation piercing contacts 5 can be pressed, using the cutting forks first, the insulation of the ladder 4 severed and then the actual conductor wire (s) are contacted.

Preferably, the cutting forks here have a radial approach 16 on which they move from the inner circumference of the sleeve 11 extend radially inward ( 29 ).

In the axial direction X, the insulation piercing contacts 5 lie in one plane, but this is not absolutely necessary, but they can also lie in two or more levels.

The sleeve 11 stands to the flange 9 open and forms a recording room 18 for cable reception 3 out.

The cable receptacle 3 is single in the 31 to 34 It shows a basic body 19 on, at least with a front in the insertion direction X section axially into the receiving space 18 the sleeve 11 is pluggable.

The main body 19 has circumferentially distributed radially outward and over a part of the axial length of the body extending webs 20 on, each with an axial channel 21 are provided, in which the ladder 4 of the cable previously stripped off one end section 2 are pluggable ( 36 ).

The bridges 20 are sized so that they each in the circumferentially existing space between two adjacent insulation piercing contacts 5 are pluggable. The conductor reception channels 21 lie on a radius corresponding to the radius on which the insertion of the insulation piercing contacts 5 lies.

Preferably is on the body 19 a seal and / or strain relief nut 22 screwable, which is also designed to be one on the cable 2 slide-on sealing ring 23 cover. Handle tabs in a rear handle portion may rotate the cable receptacle 103 To facilitate the connection of the ladder, which can be done by hand or with tools.

The Connection device is suitable both for connection different shaped cable as well as to connect unshielded or shielded Cable.

5 shows the preferably used round cable 2 , which can be designed in a shielded version. It has a cable sheath 24 and at least one, or preferably more, of the conductors 4 on, in turn, each one vein 25 as well as a conductor insulation 26 exhibit.

To make the cable, it is first stripped off at a free end ( 5 ).

Then, if necessary, the sealing ring 23 and the mother 22 pushed on the cable end and the ladder 4 are fanned out and ( 9 and 10 ) in the conductor receiving channels 21 of the basic body 23 inserted.

In the axial regions where the insulation piercing contacts 5 the ladder 4 are to contact, are the webs 20 in the circumferential direction with slots 27 provided (see 8th ) 8th also illustrates that the slots 27 the individual webs 20 are preferably axially offset from one another, since it is advantageous in terms of creepage distances and clearances, when the insulation piercing contacts are spaced apart as far as possible not only in the circumferential direction but also axially.

Preferably, conductors 4 used, their conductor insulation 26 is different colors. The cable receptacle 3 and the connector housing 7 can have corresponding markings in the correct position in the same color.

The This cable pre-fabricating person must only to be able to distinguish the color marks from each other to be able to to strip the cable and prefabricate.

After fanning and threading the ladder 2 into the conductor receiving channels 21 becomes the mother 22 on the main body 19 screwed.

Then, the thus pre-assembled cable receptacle or the base body 19 in the area of the bridges 20 be plugged into the recording room. Preferably, at one of the webs 20 a radial projection 29 provided, which is designed in the groove 14 intervene, indicating the correct orientation of the cable receptacle 3 in the recording room 18 ensures and optionally optionally also latching behind an edge (not shown) of the terminal housing can engage when the maximum axial insertion position is reached.

After insertion, it is only necessary, the cable holder 3 in the connection housing 7 to turn so that the insulation piercing contacts 5 in the slots 27 intervene, where they then the conductor insulation 26 penetrate and the conductor wires 25 to contact ( 36 ).

Further electrical knowledge is not required for connecting the cable or for inserting the cable into the receiving housing. The connection device of 1 - 36 can be compact as a connector in the so-called "M-standard" (for example M12) are formed.

37 shows a further connection device 101 for connecting a round cable 2 is designed and a cable receptacle 103 for the conductors (not shown here) of the cable 2 to this on or in insulation piercing contacts 105 a connection housing inserted into a wall (not shown here) 107 depress.

The connection housing 107 again has a flange 109 on, with which it lies at a wall breakthrough. Instead of a sleeve, it has a rectangular in cross section housing portion 111 with the insulation piercing contacts 105 and the outgoing contacts 108 on, with which it penetrates the wall breakthrough.

In the housing section 111 are here in the insertion direction X axially in turn offset each other insulation penetrating contacts 5 arranged perpendicular to the inner wall of the housing portion 111 protrude inwards.

Preferably, in each case a plurality of insulation-penetrating contacts 105 of two diagonally opposite inner sides of the housing section 111 to the inside, which has the advantage that especially many insulation piercing contacts 105 can be accommodated, which in turn makes it possible to connect a cable with a relatively large number of conductors.

The insulation penetrating contacts 105 may be distributed in the insertion in one or more rows. They are preferably in turn designed as fork contacts with insulation-penetrating cutting, but can also be formed as piercing contacts.

The corresponding cable receptacle 103 has a handle portion 103a on, which also serves as a handle to muster the necessary contacting forces.

Preferably, the handle portion 103a formed as a relatively elongated housing, which is aligned in the manner of a lever arm perpendicular to the pivot axis D.

Of the Handle portion may also include a cavity for insertion of a screwdriver contained in order to use the lever for extend the contact.

The grip section 103a can also serve for strain relief. He has an unrecognizable opening here to the cable 2 introduce. Depending on the design of this opening, this cable receptacle can be used to accommodate a round cable or a flat cable, or to receive a screw or similar device for strain relief.

To the handle section 103a is a line receiving section 103b educated. The line receiving section 103b has a preferably cylindrical base portion 103c on and two preferably tangentially to this base section 103c molded arms 103d ,

Inside the cable receiving section 103b in turn are conductor receiving channels 121 trained, which are not shown here. These conductor receiving channels extend from the base section 103a into the tangential arms 103d in there and also tangentially (almost radially to the axis of rotation) and offset in the insertion direction X to each other.

In the areas where the leaders are to contact, are in the arms 103d in turn slots 127 educated.

The connection housing 107 preferably has a front panel 129 with the flange 109 on that with an opening 130 is provided, whose cross-sectional contour of the cross-sectional contour of the line receiving portion 103b equivalent. This arrangement is similar to a keyhole in which a key (the conductor holder) can only be inserted in the correct position (alignment aid)

The function of the arrangement largely corresponds to the function of the embodiment of 1 - 36 ,

First, the cable to be connected 2 again stripped in one end and then the conductors are fanned out and plugged into the conductor receiving channels.

Then the cable receptacle 103 in the plug-in direction X in the connection housing 107 be plugged in. The connection then takes place with a rotary movement (pivoting movement) of the cable holder 103 at the handle portion 103a , Since the handle section 103a extends perpendicular to the axis of rotation D, the given leverage can be used here, the insulation piercing contacts 5 to contact, which has an advantageous effect. In addition, in this embodiment, particularly many conductors can be connected in a small space.

The connection housing 107 has a closure plate ("rear wall") with a cup-shaped recess, which serves to accommodate the cylindrical extension 110 on the cable holder 103 serves. Together with the opposite circular extension Ver they form the abutment for a non-positive twisting and contacting the conductors in the cable receptacle 103 ,
