An Independent claim for a connector plug for a wiring connection unit is also included.

Description

The invention relates to an electrical connector unit according to the preamble of claim 1 and a connector the preamble of claim 67.

DE 26 04 241 C2 is an electrical connector unit known in which the wire end of a wound around a sheet metal core Coil winding, e.g. an electric motor or a generator or the like both immediately after winding the Coil fixed in position in a simple manner and thereby loosening the Winding is prevented, as well as electrically with an electrical Conductor wire is contacted, the electrical energy introduces into the coil or forwards it out of the coil. The lead wire is passed through the housing for this purpose a motor or generator or the like from the connector unit led to the outside.

Each coil wire end is in this state of the art in each a seated in a contact element chamber of the connector, made of a stamped sheet metal electrical contact element held captive and over the contact element with a wire end electrically contacted. Here is one of the number of coils corresponding number of contact elements in the connector provided, each in a contact element chamber of the electrical Connector. The electrical connector consists of essentially from one arranged on the laminated core of the laminated core Plastic ring that is evenly spaced around the circumference distributed the contact element chambers.

The box-shaped contact element chambers are open at the top and point in two opposite walls - opposite each other - one from the top edge of the open side of the Chamber running towards the chamber bottom narrow slot for the approximately form-fitting introduction of a coil winding wire end from above. Between the slots is the floor of the Chamber a so-called ladder tamper upright. The electrical Contact element has corresponding to the chamber slots, contact slots running from bottom to top, with a passage for the conductor tamper between the contact slots is provided.

For contacting the free end of a coil wire from inserted into the top of the chamber slots until it is on the conductor tamper comes to rest. Then the electrical contact element with its contact slots from above over the coil wire and the coil wire between the slot base and the tamper fixed. The edges of the contact slots penetrate the insulation of the coil wire and thus enable an electrical conductive transition to the contact element.

This type of coil wire contacting has proven itself. she however, it is used in many variants with the same system for coil wire contacts in motors, generators, compressors or similar. For example, EP 0 002 099 B1 a straight connector strip made of plastic with in one straight row arranged contact element chambers used. The However, the contact principle for the coil wire ends is the same as in the contacting described in DE 26 04 241 C2.

A disadvantage in all cases is that the contact element chambers are arranged relatively far apart (e.g. DE 26 04 241 C2) and individually, usually by hand when installing with contact elements must be equipped. This assembly requires Skill because the contact elements are relatively small. adversely is also that the connectors require a lot of installation space and need to be attached to the coil support element in a time-consuming manner. Another disadvantage is that almost every manufacturer of electrical Motors, generators or compressors or the like self-made connector configurations used, mostly also require individualized spatial forms of contact elements, so that relatively expensive special forms of connectors and contact elements are used.

A particular disadvantage, however, is that the conductor wires, too from the outside into the interior of a motor or generator housing or compressor or the like up to the connector housing usually also by hand with the contact elements connected to produce an electrically conductive connection Need to become. This conductor wire contacting is e.g. by Clamping technology (DE 26 04 241 C2, Fig. 2, 3) or solder hole technology (DE 26 04 241 C2, Fig. 4) or mandrel technology (DE 26 04 241 C2, Fig. 5) causes. In addition, the insulation displacement technology used (EP 0 002 099 B1, Fig. 1, 1A). In all cases the assembly work is very complex and this contacting is not always optimal and safe.

In U.S. Patent No. 5,562,480 is an electrical connector unit described, especially when replacing electrical devices their place of use for the electrically conductive connection of conductor wires should be used. The connector unit has contact element chambers open at the top, in each of which one off a sheet metal stamped contact element sits. To record the conductor wires are on the underside of the contact element chambers One receiving opening each is provided, the insulated conductor wires receives. By lowering the contact element, the two has knife-blade-like blades that are spaced from each other, are arranged facing each other with the blade cut the wire insulation and the conductor wire electrically contacted. The electrical connector unit has this prior art, an inner plug part and an outer Connector part, which together form a two-part connector, as well as a socket into which the two-part plug is inserted becomes. For example, the pliers can be used with pliers Plug part from a partially assembled position where it is still loosely arranged in the outer connector part, in a complete Transfer the assembled position. Another conductor wire, to an electrical device, such as a lighting device leads is through an opening in the socket this is inserted and stands over an upper, resilient end of the Contact element with this in electrical contact.

In US-PS 5,718,599 is a connector with a mating connector and a plurality of contact elements on insulated Carrier plates described. On the carrier plates are on their contact elements running parallel to both main surfaces arranged, which in the direction of the mating connector shortly before the edge of the carrier plate facing the mating connector extend. Which are related to the two main plate surfaces opposite contact elements have opposite Polarities. The contact elements are inserted into the mating connector on the carrier plates by resilient mating contact elements, each a contact element of the connector electrical contact, pressed. On the back of the connector and the mating connector are devices for Inclusion of conductor wires provided.

The object of the invention is a connector unit for the ends creating coil windings that is easy to assemble and Guaranteed contact security and which is generally usable.

This object is solved by the features of claim 1. Advantageous developments of the invention are in the marked this dependent subclaims.

Another job is to create a connector with which the electrical connector unit can easily be connected to different Mating connector is adaptable. The task comes with a connector with the features of claim 67 solved. Advantageous further developments are in the of this claim dependent subclaims.

The invention standardizes the coil wire and conductor wire contacting in a confined space and makes installation considerably easier. It is essential that for the connections of the coil wire ends Usual contact element tamping systems are used and for the conductor wire connections a similar to the edge of the circuit board Connector element with a certain grid spacing arranged conductor tracks is created, the conductor tracks in one piece with a contact element stand and the circuit board edge element and the contact element chambers Part of an electrical connector element, in particular are a kind of connector trough in which the Bottom of the tub, in the form of a narrow plastic web protruding, the printed circuit board edge element is integrally formed, the Plastic bridge stores the conductor tracks.

The connector of the invention is advantageously on Coil body arranged. In this case, a known, mating connector connected to conductor wires in the Plug connector or inserted into the connector tray. The Conductor wires are passed through the housing of a motor, generator, Compressor or the like led to the outside. This electrical Contacting is defined as safe, repeatable and in particular possible with very little installation effort. The components of the connector unit take up very little space and are generally usable because they have standardized mating connectors can be put together.

The invention makes use of known standardized connector systems, such as for industrial devices, such as washing machines, dishwashers or the like but creates a new connector unit for the new application, with those shown for coil windings occurring, diverse problems on surprisingly simple Way can be solved. With the connector systems for Household appliances are connector systems that Contact conductor wires according to the insulation displacement technique and the are designed for contacting edges, among other things of printed circuit boards or printed circuit boards. The conductor tracks on printed circuit boards are spaced with a predetermined standardized grid. For example, the conductor tracks are in the lateral distance of 2.5 or 5 mm. The connectors are stored accordingly the contact elements with such a side spacing, that their contact spring arms or solder legs or the like Contact means arranged at this distance apart are. In the industry, the connector systems for Household appliances called "RAST 2.5" or "RAST 5". They exist usually from a connector housing and a connector tray. Store in the connector housing on conductor wires electrically connected contact elements with contact spring arms, while slots in the floor in the connector well of the bathtub, from the bottom of the tub and edgewise standing contact pins are arranged, each pin part is a contact element, the other one from the Connector has protruding solder leg and the solder legs and the contact pins have the same pitch as the contact spring arms of the connector housing. The contact pins are on the side with posts protruding from the bottom of the tub supported. The contact pins and the support posts form a sandwich-like header, on the surface the pins contact edges for contact spring arms of a mating connector provide.

The well-known, for the indirect and direct contact of Printed circuit boards designed "RAST 2.5" or "RAST 5" technology easily not to solve the problems in contacting usable from coil wire ends of a coil winding; much more was after the task regarding improvement of Contacting technology and simplifying assembly first to select the grid connection technology for household appliances and to find a new contacting element, namely in the form of the Combination of several punched and stamped from a sheet metal stamping shaped electrical insulation displacement contact elements known per se with a circuit board edge plug element, the latter from part of the connector housing, namely a continuous Bar and at least one contact conductor track an insulation displacement contact element is formed.

According to a further aspect of the invention, the invention electrical connector unit to various mating connector shapes, especially various connector standards (Rast 2.5 / Rast 5) individually adapted to the electrical connector unit according to the invention on a Mating connector matched, slot-like connection adapter can be snapped on. The advantage here is that without changing the basic element, i.e. the electrical connector unit Coil blocks can be produced, the electrical Connector unit is cast on the coil block and then Depending on customer requirements, a predetermined slot is arranged on the electrical connector unit. In particular can, depending on customer requirements, a slot for a mating connector can be attached with Rast 2,5 or Rast 5, with multi-pole electrical connector units then to Some contact points are not occupied.

An electrical connector unit 1 according to the invention (Fig. 1, 2) is preferably made of plastic and has a longitudinal front wall 2, a first narrow side wall 3, a second narrow side wall 4, a long side Back wall 5 and a bottom wall 6, each are flat and have a cuboid shape that is open at the top Form connector housing 1a. The side walls 3, 4 and the front wall 2 are approximately the same height; the Back wall 5 is made higher.

Between the inside of the front wall 2 and the rear wall 5 each extend at right angles to the front wall 2 and to the back wall 5 dividers 7, their vertical extension from the bottom wall 6 to the upper upper edge 8 of the front wall 2 is sufficient, with which the dividers are flush, see above that an upper boundary edge 9 of the separating webs 7 is formed becomes. The separating webs 7 are evenly spaced from one another in this way arranged that of the front wall 2, the narrow sides 3, 4 and the rear wall 5 limited interior space in several (here: 4) of equal size, approximately square in cross section open contact element chambers 10 is divided. The breakdown of the interior in contact element chambers of the same size takes place in such a way that the vertical central axes of the contact element chambers 10 each have a defined, constant Have grid spacing to each other, which for example 2.5 mm (corresponds to rest 2.5) or 5 mm (corresponds to rest 5).

In each case in the center with respect to the contact element chambers 10 are in the front wall 2 introduced oblique sections 11, which tapering from the upper boundary edge 8, extend downward over approximately 1/3 of the height of the front wall 2, so that each inclined leading edges 12, 13 are formed become. At the bottom of the insertion funnel Sections 11 close vertically downward narrow guide slots 14 with mutually parallel guide edges 15, 16 on. The guide slots 14 extend starting from the lower ends of the funnel-shaped sections 11 about 1/3 of the height of the front wall 2 so that the guide slots 14 approximately at a height of 1/3 of the front wall 2 above the Bottom wall 6 ends.

The support projections 17 have a substantially cube-shaped Spatial shape with an upper side 18, a lower side 19, one to the front wall 2 parallel outer surface 20 and two side surfaces 21, 22. In the top 18 is a channel-shaped Recess 23 introduced, which is slightly wider than that Width of the guide slots 14 and the groove bottom 24 rounded is trained. The channel bottom 24 closes with the lower end of the guide slots 14 from flush (see. Fig. 5, 6). In addition, the diameter of the fillet in the channel bottom 24 is somewhat larger than the width of the guide slots 14 and dimensioned such that lead wires 103, especially coil wire ends of Magnetic coils, for example an electric motor, in the trough-shaped Recess 23 can be inserted. The width of the guide slots 14 is e.g. dimensioned so that the lead wires 103 are clamped are held in the guide slots.

The from the outer sections 11 to the narrow sides 3, 4th adjacent sections of the front wall 2 have the same vertical extension on how the side walls 3, 4, so that these outer portions of the front wall 2 together with the Narrow side walls 3, 4 each have an L-shaped upper boundary edge Train 25, 26. At the level of the L-shaped boundary edge surfaces 25, 26 have the front wall 2, the dividers 7 and the narrow side walls 3, 4, each bevel 27 in the direction of the interior of each contact element chamber 10 on. The rear wall 5 is to the contact element chambers 10 out smooth and flat. The bevels 27 thus form an insertion funnel for easier insertion of contact elements 30, which from above in the direction of the arrow 97 are inserted into the contact element chambers 10 and store there. From the bevels 27 point downwards Front wall 2 and the dividers 7 each one opposite their upper end regions thicker, for example about double Wall thickness.

The rear wall 5 has approximately its entire extent the same wall thickness as the thicker areas of the dividers 7 and the front wall 2. About the level of the upper boundary edges 9 also forms the rear wall 5 a web-shaped Carrier plate 32a of a circuit board border element 32 is the same Wall thickness from such that the inside 31 of the rear wall 5 a common with the inside of the support plate 32a flat inner surface 33 forms.

The guide webs 62, 63 are each arranged at right angles to the side cheek 61 and have in the direction of the support plate 32a so that an upward open Insertion shaft for a component with a rectangular cross section, in particular a plug housing of a mating connector is formed becomes. The guide walls 60 extend vertically a piece above the free plug edge 35 of the carrier plate 32a and each form a U-shaped upper end edge 64 out. The guide walls extend vertically downwards 60 with the side walls 61 and the rear guide webs 63, each up to a little below the L-shaped boundary edges 25, 26. The front guide webs 62 sit with their lower ends on the L-shaped boundary edges 25, 26. The side cheek 61, the front guide web 62 and the rear Guide web 63 each have a support plate 32a facing Inside 61a, 62a, 63a and one of the carrier plate 32a facing outside 61b, 62b, 63b. The guide walls 60 are such at the end faces 36 of the support plate 32a arranged that the support plate 32a open to the top Insertion shaft, which is formed from the guide walls 60 is divided approximately in the longitudinal direction in the middle. For training of an insertion funnel for a mating connector are the Inner sides 61a, 62a, 63a each to the upper U-shaped boundary edge 64 chamfered out so that insertion bevels 61c, 62c, 63c.

The bottom wall 6 (see. Fig. 3, 5, 6) has a flat outer surface 70 and an inner surface 71 which the contact element chambers 10 each closes at the bottom. From the inside 71 of the Bottom wall 6 extends dome-like into each contact element chamber 10, each one essentially rectangular in cross section Ladder tamper 72, the vertical extent of which is delimited at the top by a stuffer face 73, wherein the tamper end face 73 with the groove base 24 of the support projections 17 and the respective lower ends of the guide slots 14 and the lower ends of the slots 41 are aligned. The ladder tamper 72 each have two opposite, at a distance parallel to the lateral boundary walls of a contact element chamber 10 broad sides 74, 75 and one each front narrow side 76 and a rear narrow side 77, which in each case less in comparison to the distance between the broad sides 74, 75 spaced, parallel to the front wall 2 or to the rear wall 5 run.

A contact element is seated in the contact element chambers 10 30, which is described in more detail below (Fig. 4).

The contact elements 30 are designed as a sheet metal part and have a U-shaped base body 80 with a cross section front contact tab 81, an opposite rear Contact tab 82 and the contact tabs 81, 82 on the bottom connecting web 83.

These enforcements 110 are with her Clamping edge 111 in the assembled state of the contact element 30 the narrow sides 76, 77 of the conductor tamper 72 and cause thus an additional, form-fitting mounting of the contact element 30 on the conductor tamper 72.

At the upper boundary edge 85 of the rear contact tab 82 includes itself in the middle of its extension in its extension plane lying, compared to the contact tab 82, narrower, flat-plate-shaped first conductor element 112 which, when assembled, extends up to the free plug edge 35 of the carrier plate 32a extends. At the top of the first Conductor element 112 is followed by a bent one by 180 ° Bow piece 113, to which there is a rear, down pointing second conductor end 114 connects that in the assembled State in the groove 43 of the carrier plate 32a (see FIG. 2). The arc piece 113 encompasses in the region of a groove 43 in the assembled state, the free plug edge 35 of the carrier plate 32a.

The inner flat boundary surfaces facing the carrier plate 32a 115 and 116 of the conductor element 112 and the Conductor end 114 are each flat and parallel to each other spaced such that the residual material thickness of the Carrier plate 32a in the area of the groove bottoms of the grooves 43 the distance of the inner surfaces 115, 116 corresponds to one another. Consequently are the flat boundary surfaces 115, 116 in the assembled state of the contact element 30 on the inner surface 33 and flat on the groove bottoms of the grooves 43 (see FIG. 6). The inside Flat boundary surfaces 115, 116 of the conductor element 112 and the conductor track end 114 each opposite are outside flat boundary surfaces, which - how described below - as contact surfaces 117, 118 for each Mating plug contact element 120 act (see FIGS. 2, 9).

The mating plug contact element 120 is part of a known Mating connector 121, which for contacting Printed circuit boards or printed circuit boards in their peripheral areas suitable is. The mating connector 121 has a connector housing 122 with a housing top side 123. In the connector housing 122 a mating plug contact element sits in contact element chambers 124 120. These are single ended with contact spring tongues 125 provided, which contact with the contact surfaces 117, 118, respectively. The mating plug contact elements 120 are different in FIG known way provided with insulation displacement contacts and contact and keep one in the mating connector housing 122 outgoing conductor wire 126. The side spacing of the mating plug contact elements 120 corresponds to the side spacing of the conductor track elements 112 and thus has the same standardized Grid spacing - rest 2.5 or rest 5 - on. When plugged in lies the lower boundary surface of the connector housing 122 on the one hand on the upper boundary edges 9 of the separating webs 7 and on the other hand on the upper boundary edges 46 of the stop webs 45 on. Furthermore, the connector housing 122 at least in some areas on its outer surfaces 127, 128 the guide walls 60 are positively positioned and held (see Fig. 7). The latching surface also comes in when plugged in 55 of the detent 53 with the housing top 123 to the system, see above that the mating connector 121 is held locked on the connector 1 is. Thus an unintentional loosening of the invention Plug connection prevented. Should the mating connector 121 deliberately deducted, only the resilient locking arm 50 are bent away somewhat in the direction of arrow 130, until the detent 53 next to the surface 123 of the connector housing 122 lies. The mating connector 121 can then withdrawn from connector 1 in the opposite direction of arrow 97 become.

According to a further embodiment (Fig. 8, 9, 10) of the invention electrical connector, the connector 1 two resilient locking arms 131, 132, which instead of the guide walls 60 at the end edges 36 of the carrier plate 32a in one piece, molded at right angles to the rear are. The locking arms 131, 132 have the same flat plate-shaped Spatial shape like the locking arm 50 of the first embodiment and also carry one at the top Locking lug 133, 134, which in its spatial shape is the locking lug 53 equivalent. The inner surfaces 51 of the locking arms 131, 132 are parallel to each other and perpendicular to the back 34 of the carrier plate 32a and are spaced from one another, the distance between the side surfaces 128 of the connector housing 122 equivalent. Thus, the locking arms 133, 134 act laterally Direction as guide elements for the mating connector 121 and thus replace the guide walls 60. The definition of the connector housing 122 in a direction perpendicular to the carrier plate 32a takes place, for example, via webs 135, 136, which between the mating contact elements 120 in the plug housing 122 are arranged and in the inserted state, each between two Conductor elements 112 on the inside 33 and in each case between two conductor track ends 114 on the outside 34 of the carrier plate 32a. Are in the inserted state, as in the aforementioned Example, the locking surfaces 55 of the locking lugs 133, 134 the top 123 of the connector housing 122 and secure the Mating connector 121 against unintentional removal from Printed circuit board edge element 32. By simultaneously bending away the Locking arm 131 in the direction of arrow 138 and locking arm 132 in the direction of arrow 139 can be released and thus the mating connector 121 be deducted. The rest of the construction of the connector 1 according to the second embodiment corresponds identically the structure of the connector 1 according to FIG. 1.

In the following, the assembly process for producing an inventive Plug connection in detail using the example of a Electric motor explained.

The connector 1 according to the invention is in the initial state without inserted contact elements 30, for example on one Core laminated core of a solenoid coil of an electric motor, attached. In the first step, one conductor wire end of the windings of the Electric motor from above in the direction of arrow 97 in one contact element chamber 10 inserted such that the conductor wire end is preferred each facing the rear wall 5 and the conductor wire 103 at the lower ends of the guide slots 14 and the slots 41 comes to rest. The conductor wire to be contacted thus lies 103 before inserting the contact element 30 also on the Stuffer face 73 of the conductor tamper 72 and on the channel bottom 24 of the support projection 17.

In this state, 97 is also from above in the direction of the arrow a contact element 30 with the base web 83 ahead into the contact element chamber 10 inserted (Fig. 5, 6). When inserting the contact element 30 is the conductor wire 103 in a known manner and Way contacted and held in insulation displacement technology, the IDC edges 101, 102 of the slots 99, 100 of the contact element 30 each cut through the insulation of the conductor wires 103 and thus contact and hold the lead wire 103. The contact element 30 is completely in a contact element chamber 10 inserted, its bottom web 83 is the conductor tamper 72 surrounding on the bottom wall 6 of the contact element chamber 10 on. The conductor element 112 lies flat on the Inner surface 33 of the support plate 32a, the arc piece 113 engages around the carrier plate 32a at its free plug edge 35 and thus the conductor track end 114 on the outside in the grooves 43 outsourced. The contact elements 30 can be introduced manually, be carried out semi or fully automatically. With very large ones Number of pieces, e.g. in the manufacture of electric motors are present, however, it is expedient to insert the contact elements 30 in the contact element chambers 10 semi or fully automatic perform. For semi or fully automatic assembly of the contact elements 30, it is expedient to use progressive technology manufactured contact elements 30, which according to Punching and forming processes like chains with each other via sheet metal webs are connected to remain in this arrangement or the chain formed from contact elements 30 to contact element rollers wind. Thus, the contact elements 30 can be continuous fed to an automatic feed and assembly device become. A contact element 30 sits in a corresponding one Pick-up device of the assembly machine, so the contact element 30 separated from the chain and in the designated Contact element chamber 10 inserted. During the insertion process arrives the conductor wire 103, which in the connector 1 rests in the insulation displacement slots 99, 100 of the contact element 30 and is contacted in the known insulation displacement technology and held.

After assembly, the interconnect elements 112, 114 form together with the carrier plate 32a, a printed circuit board edge element 32, as it is on the edge areas of printed circuit boards or printed circuit boards occurs, the conductor elements 112, 114 of two adjacent Contact elements 30 a fixed, standardized grid spacing to each other. Thus, as described above, a Known for contacting circuit board edges Mating connector 121 as mating connector 121 for the Connector 1 according to the invention can be used.

A connector 1 according to the invention thus combines the advantages insulation displacement technology for non-detachable contacts between contact elements and conductor wires with the advantages a detachable multiple connector using already known, available in large quantities, mating connectors 121. The special design of the contacting elements for the plug connection it also allows more advantageously Way to form a connector that meets the contacting conditions resembles a circuit board edge and thus with proven mating contact elements, e.g. Spring contact elements can be contacted reliably. Furthermore requires an arrangement as a multiple connector, For example, arranged in a row to produce one Contacting all contact points just one plug-in process, at the same time all the necessary electrical contacts between Connector 1 and that in the mating connector 121st outgoing conductor wires 103 that are in contact and contacted there end, be made. This leads in particular to one considerable simplification in the assembly process as well as an increased Ease of maintenance of the appropriately equipped devices, since the wires leading from the electric motor to the outside are not can be solved individually from the corresponding contact elements 30 must, but rather by loosening the locking devices once and disconnecting the mating connector 121 quick loosening and restoring of the contacts can take place. In addition, such an embodiment of an electrical Connection possibility, the pairing of connectors 1 and mating connector 121 with coding devices To be provided so that a confusion-free contact is ensured is. This will during the manufacturing process or during repair work on the devices in question Destruction, which is caused by an incorrect assignment of the outgoing conductor wires to the corresponding conductor wires 103 can have avoided reliably. Furthermore guaranteed such a connector 1 according to the invention has high contact reliability in operation, as it relies on proven mating connector elements 120, which are used as connectors for printed circuit boards have proven. The arrangement of the trace elements at regular, standardized intervals, in particular standard standardized grid spacings in the printed circuit board sector of 2, 5 and 5 mm is such a connector 1 with the corresponding to existing mating connectors 121 universal used. A lower variety of parts is thus achieved and this also achieved a considerable cost advantage.

The invention also provides for the circuit board edge element 32 form as a separate plug-in part, which in the carrier plate 32a contains integrated conductor elements 112, 114 and in the Housing 1a of the connector 1 can be inserted, the Conductor elements 112, 114 when inserting the circuit board border element 32 via suitable contacting elements, e.g. Contact spring tongues, electrically conductive with the contact elements 30 are connected.
