Description

The invention relates to a printed circuit board high-current plug-in device, consisting of a two-pin plug with plug part and a socket part with contact elements for producing an electrical connection and a Mehrbeinkontaktierung the contact elements of the male or female part for contacting terminal points of a circuit board.

A circuit board high-current plug-in device of this type, according to the preamble of claim 1, which enables a board / cable connection, is manufactured by Anderson Power Products, 01564 Sterling, Mass. USA expelled.

This consists of a two-pin flat plug in the way in which it is used for electric trucks. This can be screwed onto the board and there via one of its two contact elements each outgoing, to the board laterally projecting Dreibeinkontaktierung contactable at the intended connection points of the board.

The three-legged contacts consist of a laterally projecting extension of the flat contacts, projecting from these each downwardly perpendicular thereto angled terminal pins. These are introduced into board holes and soldered there.

It is possible to carry currents up to 55 A at voltages up to 600 volts through the board high-current plug-in device.

Disadvantages of such board high-current plug-in devices are that vibrations can occur between the flat contacts to be plugged two connectors in the flat contact plug-in devices used, which also transfer to the Dreibeinkontaktierung and their pins.

The assembly of boards with such board high-current plug-in devices must be done by hand, because the pins of Dreibeinkontaktierung are aligned exactly to the lower edge of housing flat contact connectors and are not firmly connected to the main contacts.

In this case, before connecting the Dreibeinkontaktierung with the main contacts of the flat contact connector, the pins of the Dreibeinkontaktierung after insertion into the board holes by soldering to the connection points and thus set the board.

It is insofar no assembly of such known board high-current plug-in devices possible by means of machines. Furthermore, the attachment of the flat contact connector to be fastened on the board is complicated insofar as this must be done, for example, by screwing.

There is no simultaneous attachment of this connector with the attachment of the pins of Dreibeinkontaktierung on the board possible.

Of the design while the known flat contact connectors of the company Anderson Power Products (eg SB 50 connector) are relatively high and wide, so that contacting the connectors on boards then encounters difficulties when these in parallel planes parallel to each other at a distance in plug-in modules are arranged.

Furthermore, such connectors are relatively long, so that a wider lateral edge of the boards for applying and screwing the housing of the flat contact connectors must serve.

In the plugged state of two flat contact connectors protrudes while the second connector far from the front of the plug-in modules. Such well-known board high-current plug-in devices are not usable in particular when board plug-in modules are arranged in cabinets, which are closable with an outer door and have only a narrow terminal space between the door and front of the plug-in modules.

Starting from a high-current circuit board plug-in device of the type mentioned above, thus, the task is to develop such that a simple attachment of the contacts of the board high-current plug-in device is placed on the board upon insertion of the pins in the circuit board hole, followed only the soldering of the pins takes place.

It should be done with the introduction of the pins in the circuit board hole at the same time a determination of the determined on the board connector housing, so that an assembly with machine is possible.

The pins and the main contacts of the connector should be mounted as possible when applied to the board and thus represent a unit. They should be already attached to the connector housing as well as the required for holding the connector housing connecting parts.

It must be feasible high currents through the contacts of the board high-current plug-in device. The connector should as possible have such main contacts that occur in a Übersteck with a second connector no vibration of the contacts with each other. On the other hand, a slight cross-over should be given.

The design of the festzustegenden on the board connector should only require a small footprint, with a contacting of boards in parallel spaced levels is possible, as used in plug-in modules for mobile or stationary telephone systems, which are housed in a large cabinet.

Since such cabinets in the connection space between the front of the plug-in modules and the front door are very narrow dimensions (eg 4 cm free space) should the space required by the specified on the board connector of the board high-current connector and the other to be plugged connector which leads the cable to be connected , be extremely low.

The pins of the Mehrbeinkontaktierung and these should be designed and soldered on the board so that good heat dissipation from the solder joint is given, and thus a low heating of the board contacts in the activated current-conducting state. The pins should as possible also be designed such that a simple soldering with a mechanical solid and electrical good contact is given.

To solve this problem, the formation of a board high-current plug-in device according to claim 1 is provided.

According to claim 1, a device is provided in which provided with pins and sockets connectors are used, as they are known per se according to device plug devices for electric trucks according to DIN 43589-1.

In this case, the socket part of the plug-in device is designed for mounting on the board, wherein the plug part comes to rest outside the field of the board and thus in the inserted state of the two connectors in the production of the board / cable connection for arranged in plug-in modules boards substantially in the connection space located in front of the outside of the plug-in modules with its contact elements and cable feed in a plane parallel to the plane of the board.

The elongated ridge-shaped contacts of the pins each have a pin portion which is bent to the board side by 90 °. These pin portions are in this case applied to each other that the bending of a central pin portion to two outer pin portions takes place earlier, inasmuch as a secure support of Mehrbeinkontaktierung is given by three spaced-pin portions and thus a high stability.

The claims 24 - 27 relate in turn advantageous embodiments of the pins of the Dreibeinkontaktierung, in particular, a good heat dissipation and thus a low heating of the pins is given.

To reduce the contact resistance while the formation of the pins and sockets of male and female part in the form of extruded contacts of claim 2 is used.

Such contacts can be plugged with high contact pressure, so far resulting in good contact between them and a low contact resistance.

According to claim 3, the housing of the plug part is constructed from a plug housing lower part and a plug housing upper part, wherein the plug housing lower part consists of two mutually angled portions at 90 °, of which one portion forms the protective collar and the other portion extending to half-height housing, half-shell-shaped, to the protective collar molded part in which the pins are inserted and plugged into the protective collar, wherein the contact pins conductor of the cable to be contacted via crimp terminals. Basically Instead of crimp connections on the contact pins and solder terminals can be applied.

This is formed as a half-shell-shaped housing part, which complements the half-shell-shaped portion of the plug housing bottom up and closes and connects with an outer end face to the inner end face of the protective collar.

In accordance with claim 5, the formation of the plug housing lower part is provided with spaced apart mutually parallel recesses, which extend in two mutually angled portions at 90 ° and thereby serve to receive the likewise angled contact pins.

The claims 6, 7 and 8 relate to advantageous embodiments of these recesses and the plug housing lower part for mounting the contact pins. The embodiment of the upper housing part, which is to be covered with the plug housing lower part according to claims 5-8, results from claim 9. There are also two spaced apart side by side recesses provided in the upper housing part, which also in two mutually angled by 90 ° sections are divided and used for guiding and embedding the part of the contact pins, which protrudes from the plug housing lower part.

In accordance with claim 11, the system of recesses in the plug housing shell is carried out according to the system of recesses in the connector housing bottom through centrally along the shell-shaped upper housing, also angled at 90 ° center web, transverse to the recesses transverse and Diagonalwandungen with omissions for storage of the housing lower part projecting upper parts of the pin sections are applied.

An attachment of the lower housing part and the upper housing part takes place according to claim 12 and 13 either by screwing the housing parts or projecting from one housing part in the other housing part snap hooks. In accordance with claim 13, both types of attachment are provided.

The formation of the socket housing with the contact sockets to be applied thereby affect the claims 14, 15 and 16. Since the socket housing to be mounted directly on the board and in the Dimension is relatively small and over a large portion of the laterally to the outer edge of the board protruding plug-neck exists, which is to be covered with the side of the plug part on the edge of the circuit board protruding protective collar, while the can body is integrally formed.

It opens to the rear, from where the contact sockets can be inserted with the contact socket on the rear side each applied Mehrbeinkontaktierung. The attachment of the contact bushes takes place via clamping pieces, which are plugged via an opening to the outside of the housing receiving slot against the outside of the contact sockets and there in an outwardly opening circumferential groove under fixing the contact sockets are latched.

According to claim 16 while the longitudinal receptacles of the socket housing are applied to the plug-in approach, where they extend insofar there in omissions, in which comes to be overseen female part of the contact socket.

The over-insertion of the plug part and socket part as the pins and sockets of these connectors is secured by an external locking of socket part and plug part by means of a latching hook according to claim 17.

For coding plug part and socket part 28 and 29, a special training of protective collar and plug-in approach of the connector is provided according to claims, which differs from the DIN standard of device connectors for electric industrial trucks.

According to claim 28 of the plug-in approach is divided into two parallel, extending in the direction of insertion spaced-apart approaches, in each of which one of the female parts of the female contacts is guided and between these approaches on the outside in the insertion direction at least one longitudinal web is performed.

In contrast, the protective collar is divided into two longitudinal recordings, wherein in the middle of this a wall runs longitudinally, which so far subdivides the protective collar into two longitudinal recordings.

The wall can also be designed as a mere wall section. In the wall or this wall portion extends a longitudinal groove in the insertion direction, which with the longitudinal web of the plug approach Overmold the connector in a suitable coding can be brought into engagement.

Advantageous orientations of the longitudinal webs applied to the lugs as web sections are provided according to claim 29. According to claim 30, the longitudinal webs are guided above the plane which is laid through the middle of the two adjacent socket parts as a connecting plane.

Claim 31 relates to an advantageous investment of the longitudinal grooves in the protective collar in the two longitudinal shots dividing wall or in the wall section provided there. The longitudinal grooves can thereby extend transversely through the protective collar from one longitudinal receptacle to the other or even partially over this section.

If the longitudinal grooves do not extend over the entire distance from a longitudinal receptacle in the other longitudinal recording, according to claim 32, a corresponding design of the plug sections and longitudinal webs is provided, which extend only with a height in the direction of the opposite approach of the plug-in approach, the lower as the distance of the two approaches of the plug-in approach is.

In accordance with claim 33, the longitudinal webs extending from the two opposing lugs of the plug-in lug are laterally offset from one another at an angle, a corresponding contact of the longitudinal grooves being provided in the wall section or the wall of the protective collar.

Through this introduction of longitudinal webs and longitudinal grooves can thereby avoid confusion of plug and socket part and in particular also of plug parts, which belong to different board high-current plug-in devices, which rest with their cables to the front of the plug-in modules.

There are mistakes of several provided within a cabinet or plug-in module connector parts avoidable, a confusion of plus and minus pole when plugging connector part and socket part and also a plug-in only one pole of male and female part, so an unwanted overhead plugging this connector with interchanging the polarity, further a permutation of cable outlets, which are directed with their plug part to the top of the plug-in module with Cable outlets, which are directed with their plug part to the bottom of the plug-in module or of various side-by-side connector parts.

According to these claims, there is a modification of the plug housing, that is, a reflection of the system of longitudinal grooves and longitudinal web about two axes.

As an additional coding, of course, in addition to the installation of longitudinal webs and longitudinal grooves and a color coding done, in this respect, the connector or board high-current plug-in devices, e.g. additionally colored for different voltages (e.g., 12 volts, 24 volts, ... 80 volts).

For the formation of protective collar and plug-in approach for coding according to claims 28 - 34 element protection is claimed.

The installation of can parts on the board takes place inasmuch as their socket parts are difficult to bend, in contrast to the contact pins of a plug part. This is especially true if they are not stamped from sheet metal, but are massively flow molded.

The compact design of male and female part is achieved in that the 90 ° bend or angulation takes place at the contact pins, which are to be applied with their connector housing outside the board and there is a cable outlet under deflection up or down.

Due to the vertical arrangement of the pin portions of the contact pins to the outwardly projecting socket parts of the female connectors of the socket part outside the plug-in area while the contact pins, which come to rest on the inside or outside of the plug part, bent with different bending ratios.

The "lower" contact pin is short and the "upper" contact pin long.

Cables with a cross-sectional area of 6 - 16 mm ² with cable deflection and strain relief can be applied via a crimp connection, whereby a very compact design of the plug part results even when a floating strain relief is applied.

Due to the special Fixieransätze on the bottom of the socket housing and there laterally applied, made of metal clips, which At its lower ends locking lugs for engaging in the connection point of the Dreibeinkontaktierung suitably applied board holes have, and by attaching the pins of the Dreibeinkontaktierung via their attachment to the female contacts directly on the socket housing can be automated assembly of the boards with the can parts of the board high-current plug-in device via robots. After assembly, the solder connection of the tripod contact can be created on the board. The shape of the pins allows a double-sided soldering in the solder bath, as settled by Kapilarwirkung also solder on the top of the board.

Due to the double-sided soldering a particularly good contact and thus a low contact resistance at the electrical connection of the pins is achieved, inasmuch as the solder joints do not heat up unacceptably despite high currents. The pins should not extend more than 2 mm from the underside of the board, preferably only 0.0 to 0.5 mm, so they do not protrude then from between 1.6 and 2 mm thick board.

The clips are preferably made of brass and have two steeply projecting forward U-shaped legs, at the end of the locking lugs are applied, which are so far elastically deformable towards each other and against each other.

The rated current carrying capacity of the board high-current plug-in device is about 80 A maximum, with a current limit is essentially given by the insulation of the cable, which must not be heated to higher temperatures than 90 ° to 100 ° C, otherwise it melts, as well through the material of the housing.

The housing and plug part and socket part is preferably made of glass fiber reinforced polyamide. The main contacts consist of silvered copper. The pins of Dreibeinkontaktierung are at the end shaped so that not only a soldering on the PCB upper and -unterseite takes place, but that these pins in the board holes are also easily swiveled, so that a floating storage of the contacts and thus better cross-over is.

The main contacts formed as contact pins and contact sockets have the advantage that they can be conducted through the used pin / sleeve contact principle via these high currents with low contact resistance.

Furthermore, these are more solid compared to flat contacts, which results in particular due to the outer latching hook between the housings of male and female part protection against vibration and a mechanical lock.

The high-current plug-in device for circuit boards according to the invention will be explained in more detail below with reference to a preferred embodiment.

As shown in the drawings, since the boards are populated, they occupy a wider, rectangular space with sufficient space between the boards to contact the board with a first horizontal connector of the high current connector this section is led to just before the insertion module front side and then at this 90 ° up or down with a second to be crossed connector, which is directed into the insertion module front page, is deflected.

In the high-current plug-in device 1,1 ', 1 "while main contacts 12,13; 14,15 are used, which are formed according to the pin / sleeve principle, which is used in device plug-in devices for forklifts and similar electric vehicles. see DIN 43589-1)

The socket part 10 formed with socket parts 33 on the contact bushes representing main contacts 14, 15 is supported on the board to be contacted via a special latching and charging device and is thereby shown in FIG. 2 via a tripod contact arrangement applied to the contact socket rear side 16, 16 ' 18,18 'and their on the board to be made solder terminal 44 (see Figure 17) electrically contacted on the board.

The main contacts 14,15 with the front socket parts 33 of the socket part 10 are thereby in the socket housing 11 via a from the top of the housing between the elongated main contacts 14,15 insertable, resilient clamping piece 35 'set (Figure 2, Figure 5c).

This engages in a radially recessed circumferential groove approximately halfway along the main contacts 14,15. The shaped socket parts of the socket part 10 stand up to the front part of the socket housing 11, which is formed there as a plug-in extension 25, as for device plug-in devices of electric industrial trucks is known, but the plug-in approach is divided into two separate approaches to separate encapsulation of the socket parts.

While the socket housing 11 is formed substantially in one piece and in particular is not divided into a socket housing lower part and upper part and thereby according to the substantially straight-shaped main contacts, which have only at the end an outwardly angled Dreibeinkontaktierung straight extends, the plug part 6 a initially the can part 10 facing straight, to be covered first portion, which is formed by the protective collar 24 of the plug housing, which surrounds there freely protruding pin portion 32 of the main contact 12,13 of the male part 6, and further to an angled by 90 ° second housing portion.

In this case, there is a plug housing lower part 7 and a smaller section in the form of a plug housing upper part 8, which complement each other via the angled second housing section of the plug housing lower part.

While the plug housing bottom part 7 has the laterally outwardly closed protective collar 24 of the plug part and adjoining it only in the lower part, at 90 ° to the protective collar finally angled housing portion, the plug housing upper part 8 is only as a substantially straight housing half shell, which is the corresponding Half shell portion of the connector housing lower part 7 added.

The plug housing upper part 8 in this case has as a connection to a vertical end face 8 ', which comes to rest against the free inner end face 8 "of the protective collar 24, and offset laterally right by 90 ° another terminal side 72, to which a guide portion 23 for there in vertically displaceable strain relief clamp 9 is applied and thus the openings for a two-pole cable to be contacted.

The construction of the plug housing bottom part 7 results in detail from FIG. 3a-3d and the construction of the plug housing top part 8 from FIG. 4a-4d.

The arrangement of the main contacts 12,13 of the plug part in the plug housing lower part 7 is shown in Figure 2.

These contact pins performing main contacts have at one outer end in each case a crimp connection 77 for pressing a cable with a suitable large line cross section (eg 6, 10, 16 mm ² ) and are angled with their pin portions 32 of this crimp laterally to the right by 90 ° ,

They then extend in each case with these straight pin portions 32 in the middle in the two receptacles of the protective collar 24. The main contact, which comes to rest in the region of the 90 ° bend of the plug part inside, is shorter than the outside to be outgoing main contact 13th

The pin portions 32 of the main contacts 12,13 as well as the socket parts 33 of the main contacts 14,15 are not outwardly on the protective collar 24 of the plug housing or the plug projection 25 of the socket housing over so that they completely encapsulated in the protective collar or plug-in approach to the outside are and are thus protected against unintentional electrical contact, for example, by contact with a tool.

Due to the angled 90 ° main contacts 12,13 of the connector part 6 is given at the outer crimping terminal 77 a receptacle for cables with cable deflection for board connection, lines in a cross-sectional measurement to 16 mm ^{2 can be} fixed.

By provided on the outer terminal side 71,72, consisting of a Zugentlastungsschelle 9 and guide portions 23 of the plug housing lower part and the plug housing upper floating tension relief optimal guidance of the cable to the respective crimping terminal 77 of the main contacts 12,13 is ensured.

On the inside 27 of the plug housing green part are, as well as on the corresponding inside of the plug housing upper part according to Figure 3d and 4d, webs 50-53 and elongated recesses 54,55 arranged to guide and embedding the two juxtaposed main contacts 12,13 of the two-pole plug part.

The arrangement of the recesses 54,55 and longitudinal and diagonal webs 50-53 in the plug base corresponds to the arrangement of the recesses 54 ', 55' and webs 50'-53 'in the connector shell, wherein the plug base also the protective collar 24 is formed, so that the half-shell-shaped first portion is extended by a second portion.

The recesses 54, 55, 54 ', 55' are each initially guided straight from the connection side 71, 72, where the guide sections 23 of the strain relief clamp are applied, the area of the recesses to the end wall 8 'adjoining the protective collar being then in each case 90 ° is bent.

Centered between these recesses of the central web 50,50 'is guided, which has a corresponding turn at the outer end.

To stiffen the bent portion, the webs are each in the recesses 54,55; 54 ', 55' in each case as diagonal webs 51,52; 51 ', 52' and in the outer recess additionally as a transverse web 53,53 'running.

The plug housing lower part 6 and the plug housing upper part 8 are formed flat in the region of the end faces 56, 57 of their half-shell sections and can be placed on one another.

In a threaded bore 58 of the plug housing lower part 7, the plug housing upper part is fixable by means of a screw, which is guided through a through hole 59 of the plug housing upper part and is fixed there with its head on the outside of the housing.

The fastening of plug housing lower part 7 and plug housing upper part 8 is further effected by the snap hook 35 shown in Figure 4b and 4e, which extends there laterally upwards with a long web-shaped portion right and left in the recess formed for the Zugentlastungsschelle 9. This guide 68 is formed by the guide portions 23 of the strain relief clamp.

The protruding snap hook 35 engage in a according to Figure 3e in the connector housing lower part downwardly extending recess for guiding the Zugentlastungsschelle 9, wherein on the local outer wall in each case a radially recessed locking surface 60,61 is applied.

After attachment of the plug housing upper part against the lower part, the inserted between these main contacts 12,13 are set in the connector housing and protrude the protective collar.

For attachment of the plug part 6 and the socket part 10, a latching hook 26 is provided according to Figure 3a, b, c and d respectively on an outer side 24 'of the plug housing lower part 7 in the region of the local protective collar 24, which is designed as a two-sided lever and thus by pressure the one end of the lever with its latching nose can be pivoted outwards.

As can be seen from FIG. 2, this latching nose engages behind a transverse rib 63 on the outer wall of the can housing 10. This transverse rib is applied laterally behind the insertion projection 25 of the socket housing 10, so that by the latching hook 26, an overflow of protective collar 24 and plug-in projection 25 is not hindered.

In order to avoid a mismatch of the two-pole high-current plug-in device 1,1 ', 1 "with another high-current plug-in device or plug part and socket part with each other, at least one in the wall of the protective collar is inwardly to one of the local longitudinal receptacles 30, 31 opening longitudinal groove 49 applied (Figure 2, Figure 5a, c).

Accordingly, a longitudinal web 48 is applied to the outside of the insertion projection of the socket housing 11, which engages with proper plugging with the plug part 6 in the longitudinal groove 49 of the plug part 6 and otherwise prevents over-insertion.

As can be seen from FIGS. 5a and 5c, the insertion projection 25 of the socket housing 11 consists of two parallel, mutually spaced, tubular projections 25 ', 25 ", which are closed to the front except for a passage opening for the pin sections 32 of the contacts of the plug part 6.

Since these lugs 25 ', 25 "spaced from each other, there is enough space between them to guide the longitudinal web 48, which engages in the center of the protective collar longitudinal groove 49 when plug connector part 6 and can part 10, since the protective collar 24 in Longitudinal recordings for the two pin sections 32 is subdivided by a transverse wall 62 into which the longitudinal groove 49 can be guided, which opens on one side into one of the longitudinal receptacles of the protective collar 24. In each of these, one of the pin sections 32 comes to rest and is laterally outward the longitudinal web 48 provided approach of the plug-in extension 25 can be inserted.

As can be seen in FIGS. 4a-4c, the socket housing 11 has on its outer wall, in contrast to the plug housing 6, 7 Holder for a latching and loading device for fixing the socket part 10 on the board 2.

For holding the socket housing 11 on the board are at the bottom on both sides of the socket housing at a distance from each other two outwardly projecting Fixieransätze 19,20; 19 ', 20' created. These fixing lugs are dimensioned such that they can be inserted or latched into board bores 43 (see FIG. 17).

For additional attachment of the socket housing 11 by means of the locking and insertion device to be used serves a U-shaped clip 21,22 on both sides of the socket housing. This clip stands out laterally with its two locking legs over the underside of the socket housing 11. For holding the clip on the socket housing 11 serves an elongated bracket 38,39 on each side of the housing, the clip is inserted into this bracket from above and comes with an outer stop surface laterally outside the support. In order to prevent pressing out of the clip from this bracket when attaching the socket part 10 on the board 2, it is provided at a distance above the bracket centrally to this a radially projecting lug 66 as a clip-locking.

The clips 21,22 are made of metal, so in contrast to the Fixieransätzen 19,20, 19 ', 20' of the socket housing 11 is not made of plastic. They have at the end of their locking legs latching lugs 36,37; 36 ', 37' on.

After insertion into the board holes to be provided on the board, the locking legs of the clips 21,22 can be clipped into these not only by utilizing spring and clamping forces, but also solder directly to the board.

The formation of the main contacts 14,15 of the socket part 10 with outer socket parts, which protrude as contact portions 33 in the guide projection 25 and are to be introduced into the socket housing 11 of Figure 5a, b, c, results from Figure 2.

The structure of the main contacts 14,15 corresponds to the structure of the contact sockets, which are used in the socket part of electric-Flufzeugzeug plug devices.

In this respect, the front socket part, in which to conduct higher currents a solid pin contacts 12,13 of the plug part 6 is to be plugged, split in the longitudinal direction, wherein on the Socket opening outside a clamping ring comes to the plant. This construction results in a good contact of the contact pins 32 in the sleeves 33 of the main contacts of the can part 10th

In particular, optimum current transmission over the section of the sleeve contacts in the region of the width of the clamping ring is ensured. The contacts are extruded to ensure a firm crossover and low contact resistance.

The main contacts are made of copper and silver plated outside.

At the contact socket rear sides 16,16 'are each the connections for the Dreibeinkontaktierung 18,18' created. This Dreinbeinkontaktierung each has three after a longitudinal portion by 90 ° angled terminal pins 41, two of which protrude outwardly and a centrally applied to gap applied pin retracts inwards.

These pins 41 are formed directly on the sleeve contacts on the local contact socket rear side 16, 16 'on a bolt section 17.

The contacting of each female or sleeve-shaped main contact 14,15 on the board thus takes place in each case via a triple solder connection via the three provided pins 41st

In contrast to only one or two pins, is made possible by three pins and the shape shown specifically in Figure 17 of the pins to perform a double-sided soldering in the soldering on the board front and back side, which in the soldering on the back of the circuit by Kapilarwirkung between Placing the pins and their board hole Lot on the top of the board and insofar as the double-sided soldering and mechanically fixed connection of each pin is given.

As can be seen from FIG. 17, the connecting pins 41 have a section which is tapered in cross-section over the upper side of the board, wherein the latter has a chamfer 45. At this chamfered section then follows a straight section with the same cross-sectional dimension. This stands out of the approximately 1.6 - 2 mm thick board to the outside of the back of the board, wherein the pin has an end portion, with outer sides 46, which are chamfered towards the pen tip. This tip protrudes from the underside of the board for a maximum of up to 0.5 mm.

The Lötanschlüsse side of the terminal pin 41 on the board top and bottom side of the board are each represented by therein circumscribed solder 44.

As already stated for the plug housing part 6, 7, the cable to be pressed in the crimp connection 63 of the main plug contacts 12, 13 is guided with its two connecting conductors in each case through a strain relief clamp 9. It is a floating strain relief, since the strain relief clamp 9 in a longitudinal recess (guide 68) between a front and rear guide portion 23 is displaceable perpendicular to the contacts, which is formed from Wandungsabschnitten the housing base and housing top.

The strain relief clamp 9 in this case has the Zugentlastungsschellenobererteil 9 'according to Figure 6a, b, c and the Zugentlastungsschellenunterteil 9 "according to Figure 6d, e, f.

These upper and lower parts each have on the right and left receptacles 67 for introducing the clamped conductor of the two-pole, to be connected to the main plug contacts cable.

In the middle between these recesses a longitudinal web is guided, in which a through hole 59 and a bore 58 is provided with an internal thread, so that the upper and lower part of the strain relief clamp 9 are screwed against each other.

In Figure 7a, b, the angled main contacts 12,13 of the connector part 6 are shown in a side view, which are formed by contact pins.

These each have the outer crimp connection 77, which is designed in the form of a sleeve which opens on one side and merges with the opposite side into an inner diameter tapered pin portion which forms the pin portion 32 of the main contacts 12,13.

The main contact 12 has a relation to the main contact 13 shorter pin portion, wherein the length of the sleeve-shaped portion of the crimp 77 is the same.

In FIGS. 8-16, six plug housings 7, 8 and four socket housings 11 are shown, in which in the longitudinal receptacles 30, 31 of the protective collar 24 or between the tubular projections of the Plug neck 25 longitudinal webs 48 ', 48 "and on the opposite side longitudinal grooves 49', 49", 49 "'are mounted.

The longitudinal grooves and webs are laterally displaced centrally and aligned in different directions, with a pairwise arrangement of longitudinal webs or longitudinal grooves in the protective collar 24 and plug-in projection 25 is provided.
