Abstract

For ease and modification flexibility in the manufacture of jumpers in a plug connector, according to the invention the housing cover (10) is equipped with a contact carrier (3) which is releasably clipped thereon. The contact carrier (3) can be made in two parts and can have an upper part (1) and a lower part (32). These can be separated from one another and joined together in order to accommodate individual U-shaped contact pins (8, 8', 8'') for bridging socket contacts (28) of the plug connector or also in order to remove and/or replug said pins. If necessary, the complete contact carrier (3) can also be exchanged for another contact carrier having a different bridge assignment. As a result, the operating state of an electrical system can be individually defined and modified. When the housing cover is open, an external test plug can be plugged in for maintenance purposes. Furthermore, the contact carrier (3) can have a certain mechanical "play" for tolerance compensation in the housing cover (10) so that the contact pins (8, 8', 8'') and the contact carrier (3) are not subjected to mechanical stresses during opening and closing of the housing cover (10).

Description

Connectors with shorting bridges

description

The invention relates to a contact carrier according to the preamble of the independent claim 1.

Furthermore, the invention is based on a method for changing the operating state of an electrical system, in particular a

Escalator, according to independent independent claim 20.

Connectors with shorting bridges are used in particular for

Performing maintenance on electrical equipment, e.g. on escalators, needed.

State of the art

Functionally comparable connectors have been known since about 1996 in the prior art. The company "HARTING electronic components Ges. M.b.H." at that time in cooperation with the company "Compact Electric" in Vienna for the company "Schindler" (today's name: "Schindler escalators International GmbH") six-pole

Heavy duty connector with mounting housings ago, the

Mounting housing swiveling, in particular hinged and zuklappbare

Have housing cover. In each of these pivotable housing covers a printed circuit board with up to six soldered thereto contact pins. These contact pins are usually electrically connected in pairs via one conductor of the printed circuit board and thus form an electrical shorting bridge, often called "bridge" in the short form.

Furthermore, this connector has a Isolierköper, are arranged in the six contact sockets. By closing the housing cover, for example, two of the contact sockets "bridged", ie by one of Bridges are electrically connected to each other. Due to the course of the printed conductors on the printed circuit board, the contact pins belonging to a bridge, and thus also the contact sleeves opposite them, are to be bridged to corresponding pairs

configurable. By changing the printed circuit board against another corresponding printed circuit board, these pairings can be adapted to the respective requirements.

By closing the housing cover, operation of the electrical equipment, e.g. the escalator, done. The closed housing cover thus corresponds to the operating state. When the housing cover is open, operation is interrupted and instead a test plug can be plugged into the connector as a mating connector. The open housing cover thus corresponds to the maintenance condition.

The basic housing design of these connectors corresponds to the then prior art. For example, was a comparable

Hinge joint mechanism of the housing cover already described in the document DE 24 51 662 A1. Furthermore, the document EP 0 731 534 A2 discloses a so-called "easy-lock" locking bar, the side parts of which have pockets in each of which a spring element and a rocker-like locking element are arranged

EP 0 957 540 B1, which describes a particularly good EMC ("Electromagnetic Compatibility") - protected connector housing, inter alia, a sealing ring is mentioned, with which the connector housing against a mating connector or against the own housing cover are sealed against the ingress of dust and moisture can. In practice, the functionality of a connector, in whose housing cover electrical short-circuiting bridges are arranged, basically proven. However, it has sometimes been criticized that the contact pins inserted in the contact sockets together with the

During the pivoting movement of the housing cover, contact bushes exert a certain mechanical moment on the circuit board, so that the circuit board is subjected to mechanical stress. Also, the implementation of a high number of bridges using a simple circuit board is at least difficult or even impossible. This is of particular disadvantage because such a bridging function is increasingly being used for connectors with a larger number of contact pins, e.g. for ten-pin connectors, is required.

In the current state of the art, there is a further disadvantage in the installation effort of changing the printed circuit board or the

cost-intensive exchanges of the complete housing cover, if the configuration of the bridges is to be changed once.

Accordingly, the option of a comfortable and

inexpensive change of the bridge assignment, e.g. for the change of the operating state, desired. For some applications, a high current carrying capacity of the bridges is still required.

The German Patent and Trademark Office has researched the following prior art in the priority application for the present application:

task

The object of the invention is to provide a robust device, which is a handy switching between a Maintenance and an operating condition of an electrical system, such as an escalator allowed. It should be accessible as many contact sockets of a connector in the maintenance operation an external test plug and be pairwise bridged in the operating state.

In particular, the configuration of the bridges should be comfortable and inexpensive to change.

This object is solved by the features of the independent claims.

A contact carrier serves to receive a plurality of U-shaped contact pins for the production of shorting bridges and is adapted to be detachably arranged in a housing cover of a connector. The contact carrier may in particular be designed in at least two parts, i. it can for example be made in two parts, three parts, four parts, n parts. In particular, the contact carrier may be at least two-part, at least three-part, at least four-part, at least n-part.

Advantageous embodiments of the invention are specified in the subclaims.

The contact carrier is advantageously made of an electrically insulating material, preferably plastic. The contact carrier can be releasably held in the housing cover of the connector and thereby preferably movable within a predetermined tolerance range. The arranged in the contact carrier U-shaped contact pins serve the

Production of electrical shorting bridges opposite

Contact sockets, which are arranged in an insulating body of the connector. Cable connection side, these contact sockets, for example, with components of an electrical system, in particular an escalator, be electrically connected. Due to the multi-part, so at least two-part, eg at least three-part shape of the contact carrier, it is advantageously possible that the paths of the U-shaped contact pins, which form the bridges (short for "electrical shorting bridges"), intersect within the contact carrier In the configuration, the U-shaped contact pins can be individually removed and / or inserted into the contact carrier, eg by separating and joining the several parts of the contact carrier, for example, a particular bridge can be removed and / or added as needed with very little At the same time, the U-shaped contact pins can be relatively large compared to the printed conductors of a printed circuit board

Have cross-section. This is particularly advantageous because this significantly improves both the mechanical stability and the current carrying capacity of the bridges compared to the printed circuit board solution.

Of course, in a special embodiment, the parts of the multi-part contact carrier after insertion of the U-shaped contact pins to lock together and / or glued to each other. In the case of gluing is from this time on but the possibility of their

Removal and thus the possibility of a changed configuration of this contact carrier is no longer given or at least strong

limited. By contrast, the locking also allows a later reconfiguration of this contact carrier.

Once the contact carrier on the housing cover of the

Connector housing is arranged, the U-shaped contact pins are able to be automatically inserted by closing / closing, in particular by means of a pivoting movement of the housing cover in the respective contact socket of the connector and thereby each a designated female contact pair electrically bridge, ie the two contact sockets, which form this pair, electrically conductively connect to each other.

The contact carrier is extremely advantageous in its use compared to a solution in which simple contact pins are soldered to a printed circuit board or in the U-shaped contact pins only in the

Housing cover inserted and, e.g. with a plastic compound, are overmolded.

In contrast, the multipart contact carrier has e.g. the advantage that individual U-shaped contact pins at any time manually removed from the contact carrier and / or can be used in it. Thus, as will be explained later, the operating state of the electrical system, e.g. the escalator, to be changed.

By a certain so-called "game" of the contact carrier relative to the housing cover, in which it is held so mechanical tolerances can be created, which are necessary to close the housing cover of the connector housing without the generation of unwanted mechanical stresses, ie collapse, or open, so The solution according to the invention thus has the advantage that it is stable and flexible.This play can be realized, for example, by virtue of the fact that the housing cover can be unfolded, at least partially, into the contact sockets of the connector At least one, preferably two positioning pins are arranged, which have a circular cross-section

Positioning pins have suitable positioning openings, which have a slot-like cross section, wherein the minor axis is preferably aligned parallel to the axis of rotation of the housing cover and the main axis is preferably aligned perpendicular thereto. As a result, the contact carrier in the pivoting direction of the housing cover the have said tolerance, be positioned perpendicular to and

at the same time with his snap arms in the counter - restraints of the

Housing cover to be held.

Furthermore, the configuration of the bridges within the given by the contact carrier options at any time a desired changed function of the operating state can be adjusted

for example, by a suitable replacement, arranging, removing and / or adding individual U-shaped contact pins in / from the contact carrier.

In a preferred embodiment, in addition to its at least two parts, the contact carrier can have a third part which can be attached to the interconnected parts, in particular a lid which can be latched onto it. For example, the contact carrier may have at least one upper part and one lower part and the said cover, so that the contact carrier is in this case at least three parts in total. Then the upper part can first be attached to the lower part. The lid may then be attached to the top and in particular attached to the bottom, e.g. be locked. For this purpose, the lid may for example have fastening tabs with snap-in windows with which it latches on Rastanformungen of the lower part.

By means of this latching, the upper part can also be held on the lower part in a preferred embodiment. From

On the other hand, it is particularly advantageous if the lid has a protective surface, with which it rests against the upper part in the mounted state and thereby at least one or optionally several more through the upper part, in particular by at least one

Contacting the upper part, covering running contacts. Through this protective surface, for example, a manual contact of at least one current-carrying contact pin is reliably prevented in this way. The lid can therefore a double function, namely both an electric Safety function as well as a mechanical, constructive

Attachment function, meet.

Of particular advantage is the electrical safety function

in particular, because - at least theoretically and / or in the event of damage - when opening the housing cover of the connector there is a risk that the releasably attached contact carrier on the one hand unintentionally detached from the housing cover, while the therein recorded contact pins on the other hand still inserted into the insulator and thereby are held mechanically. Of course, this does not correspond to the intended use of the

Contact carrier, but in case of misuse or damage is a potential source of danger, because ultimately the

Contact pins in an electrical contact with in the insulating body

arranged socket contacts are available. In this case, at least one of these socket contacts, and thus also the respectively associated contact pin, worst case even lead to life-threatening electrical voltage.

By the said cover of the contact carrier and in particular its protective surface can be safely avoided a manual contact with this contact pin but also in such an error.

Advantageously, such a risk may be due to a fundamental misoperation, e.g. by untrained staff, which the

Contact carrier not fastened in the lid, but in disregard of appropriate safety regulations inserted directly into the insulator, safely prevented.

In particular, it is particularly advantageous to glue a user-side final individually configured, ie provided with the desired U-shaped contact pins, contact carrier, and in particular his cover with the other parts, in particular To glue with the upper and lower part, because the lid is then finally no longer removable.

In order to be able to change the bridge assignment even more flexibly, e.g. In order to operate the connector with a converted system or to fundamentally change the operation of the system, in an advantageous embodiment, of course, another contact carrier, which has the new, desired configuration, exchanged for the currently used contact carrier, so instead of being mounted in the housing cover , This will result in a cost effective and

unobtrusive way also new bridge connections allows for the exchange in the contact carrier no contact receptacles are provided.

Just such an exchange of the contact carrier against another contact carrier is by latching and positioning of the respective

Contact carrier and the housing cover also very comfortable and inexpensive to perform. This variant offers itself, as described above, e.g. if the currently used contact carrier does not support the course of at least one particular desired bridge by its contact recordings.

In particular, this method is suitable for the use of bonded contact carriers, in particular of contact carriers with

Safety reasons glued lid.

This way the user can apply for an existing one

Connector Different contact carriers with different bridge functions individually configured and for different

Applications are provided. Of particular advantage may be the different ones

Contact carrier with features, in particular optical features, to make distinguishable, in particular the contact carrier in

different colors to facilitate their assignment to the particular application (e.g., escalator should run upwards):

Contact carrier is green; Escalator should run downhill: contact carrier is red, etc.).

Alternatively or additionally, special assignments of the

Contact sockets can also be realized on the cable connection side, which however is sometimes undesirable in practice, e.g. because of a

basically fixed, e.g. standardized, occupancy of

Contact jacks. Also in this case, the releasably fastened

Contact carrier an extremely flexible and at the same time very comfortable to use solution that adapts to a predetermined cable connection side occupancy easy to handle, flexible and cost-effective.

The following are the particular advantages of the multipart

Contact carrier to be exposed.

For example, a contact carrier for a ten-pin connector is adapted to receive five U-shaped contact pins, which then each bridge between the female contact pairs 5-10; 4-6; 1 -7; 2-8; Make 3-9. If the bridge between the contact sockets 5-10 and the bridge between the contact sockets 2-8 is no longer desirable, the corresponding U-shaped contact pins can be removed by suitable separation of individual parts of the contact carrier with little effort from the contact carrier. Advantageously, the

Contact carrier previously taken to the housing cover and then attached to this again, which is possible in particular by the common locking mechanism with very little effort. thereupon when closing the housing cover only the

Contact socket pairs 4-6; 1 -7; 3-9 bridged.

Will later be e.g. one of these bridges needed again, the previously removed U-shaped contact pin can be installed with very little effort in the same way again in the contact carrier. This process of installing and removing individual contact bridges can be repeated by simply separating the individual parts of the contact carrier nondestructive and almost as often as what the user, possibly in

Connection with the cable connection side assignment of the

Connector, a very flexible and especially very inexpensive configuration changes allowed.

In particular, the two-part contact carrier consists of an upper part and a lower part, which can be joined together to form the contact carrier.

The technique described below therefore, for example, refers to the advantageous embodiment of a two-part contact body with the upper and the lower part. However, it is clear to those skilled in the art that this doctrine as well as any multi-part design, ie

For example, on a 3, 4, 5, n-part design of the

Contact carrier can be easily transferred.

Both the upper part and the lower part may preferably have a substantially cuboidal basic shape and each have a contact surface and, opposite thereto, a plug-in region. When joining the upper and the lower part of the plug-in area of the upper part can be arranged on the contact surface of the lower part.

In the contact surface of the upper part can be at least one elongated

Well be arranged as a contact. In the contact area of the Bottom parts can also at least one elongated recess as

Contact be arranged. Overall, the contact carrier, e.g. is intended for use in the ten-pin connector, have five contact receptacles. The contact surface of the lower part can then, for example, have four contact receptacles in a preferred embodiment and the contact surface of the upper part can accordingly have a contact receptacle. Some of the contacts may be the same length. Some of the contacts may differ in length.

Both the upper and the lower part can lead to the respective contact surface at the ends of each contact

Through openings for contact implementation, in particular for

Carrying plug-side end portions of the U-shaped contact pins having. In addition, the lower part can also have more

Through openings have, which in the assembled state of the contact carrier to the through holes of the upper part

connect. As a result, a U-shaped contact pin inserted into the contact receptacle of the upper part can be guided with its plug-side end regions both through the through openings of the upper part and through the further through openings of the lower part so as to fulfill its bridging function relative to the respective contact bushes.

The upper and the lower part can be used for mutual connection

Entrastung locking means, such as latching hook and recesses have. These locking means may additionally have a positioning function. Alternatively or additionally, the upper and lower parts may have separate positioning means for mutual positioning in their assembled condition. For example, the upper part can have positioning pins at its plug-in area, and the lower part can match at its contact surface Own positioning recesses. In a very special

Design upper and lower part can be glued to each other after inserting the U-shaped contact pins, which increases the stability but limits the flexibility. However, bonding does not have to be carried out at the factory, but can also be carried out by the customer after the final configuration / assembly of the contact carrier, as a result of which an individualization of the bridge assignment can still be carried out flexibly.

The contact carrier may in turn comprise polarizing and latching means. In this case, the polarizing agent may consist in a preferably L-shaped polarization element of the contact carrier, that on the contact carrier, e.g. on the upper part, can be molded. The

Locking means may consist in one or more latching arms of the contact carrier, e.g. can be formed on the lower part. These latching means can latch on counter-locking means of the housing cover.

In particular, the contact carrier may have latching arms which

Lock the counter-latching arms of the housing cover. In addition, the housing cover may have positioning pins and the contact carrier may have positioning openings. This has the advantage that the contact carrier in relation to the insulating body has a defined position, so that the U-shaped contact pins held by him

Immerse contact recesses of the insulating body to contact the arranged therein contact sockets. Between

Positioning pin and the positioning holes may exist the said game to allow a slight tilting movement of the contact carrier relative to the housing cover.

The lower part can continue at its plug-in area at said through holes hollow cylindrical projections for

mechanical guidance and better mutual electric Have insulation of the plug-side end portions of the U-shaped contact pins.

The U-shaped contact pins are advantageously made of an electrically conductive material, preferably metal, and have

in particular a rectilinear middle region, the

advantageously has the same length as at least one

Contacting the contact carrier. At both ends of the

Mid-range plug-in end areas are bent at right angles. For this purpose, the U-shaped contact pins between the central region and the plug-side end regions have a bending region, which naturally can have a certain curvature. The middle region of the U-shaped contact pins can thus be inserted into the respective contact receptacle. The right-angled to the central region extending plug-side

End portions are simultaneously plugged through the respective passage openings, so that they at the plug-side end of the lower part to

Contacting the contact bushes protrude from the lower part. The at least one U-shaped contact pin, which are arranged on the upper part, can be passed through the further through openings of the lower part. At the contact surface of the lower part so can the plug-side end portions of all U-shaped contact pins protrude and may preferably be partially covered by the said hollow cylindrical projections of this plug-in portion, but at their ends protrude from it to be plugged into the respective contact sockets.

There may be provided U-shaped contact pins in various configurations. These may differ in particular by the length of their middle region and / or by the length of their plug-side end regions. For use with a two-part contact carrier, which thus consists of an upper and a lower part, offers the Use of U-shaped contact pins, which differ from each other at least in the length of their plug-side end portions.

A first contact pin, which is intended for use in the upper part, advantageously has longer end regions than a second contact pin, which is intended for use in the lower part. Finally, the end regions of the first U-shaped contact pins must pass through both through openings of the upper part and two further through openings of the lower part and optionally through the cylindrical projections of the lower part and further protrude from the insertion region of the lower part to contact the contact sockets. The end portions of the second U-shaped contact pins need only the

Through opening of the lower part and possibly the

go through cylindrical projections and protrude from the plug-in area to contact the respective contact sockets.

Furthermore, the U-shaped contact pins may differ by the length of their central regions. This determines the length of the bridge, which is dictated by how far the respective ones are

Contact sockets in Isolierköper of the connector are arranged away from each other.

In this way, a set of suitable U-shaped contact pins can be assembled for use with a particular contact carrier, of which at least some differ in their design. Preferably, at least two of these U-shaped contact pins differ by the length of their central regions and / or by the length of their

plug-in end areas.

The inserted into the lower part U-shaped contact pins can be fixed by its assembly and possibly locking with the upper part. The at least one inserted into the upper U-shaped Contact pin can be fixed by attaching the contact carrier

Housing cover to be fixed.

The connector may include at least:

An attachment housing with the housing lid held open and closed by it;

An insulating body with the contact bushes arranged therein; A locking mechanism for locking the housing cover in the closed state.

As already mentioned, the contact carrier can be releasably fixed in the housing cover, in particular locked.

For this purpose, the contact carrier may have latching arms which are able to releasably latch with counter-latching arms of the housing cover.

By collapsing the housing cover, at least one contact pin can be inserted with its two end regions into two of the contact bushes in order to electrically connect them to one another, ie to bridge them.

As already mentioned, the contact carrier can have a polarizing agent, for example an L-shaped polarization element. The insulating body may have a mating polarizing agent, e.g. a Polansationsausnehmung, in which the polarization element of the contact carrier automatically engages when closing the housing cover. Opposite, the insulator can be another

Gegenpolarisationsmittel, for example, have a polarization bar, which prevents relative to the insulator relative to the insulator closure of the housing cover when the orientation of the contact body.

The contact carrier can in the housing cover within a

predetermined mechanical tolerance range be fixed to move can open or close the housing cover of the connector housing without the generation of unwanted mechanical stresses, even while the at least one U-shaped contact pin plug side, in particular with its plug-side ends, at least partially, is inserted into the contact sockets of the connector.

Finally, the plug-side end portions of the U-shaped contact pins naturally move longitudinally in the contact bushes, while the housing cover performs a rotational / pivoting movement when closing and opening. By the said mechanical

Tolerances between the contact carrier and the housing cover these two movements but allows without the occurrence of mechanical stresses.

Such a connector can be installed as a measuring interface in an electrical system, such as an escalator. For this purpose, on the cable connection side, at least two electrical components of the system, which are to be electrically connected to one another in the operating state, are connected to the connector, i. electrically connected to one of the contact sockets of the connector. By opening the housing cover, the operating state can be switched off, i. the electrical components are no longer electrically connected to each other. In this condition, a test plug of a measuring device may be plugged onto the connector and the components may be separately, i. electrically decoupled from each other, to be tested. To establish the operating state of the

Test plug removed and the housing cover closed again. Thus, the respective contact sockets are bridged again and the connected electrical components of the system are again electrically connected to each other.

Sometimes, however, the case may occur that the operating state is to be changed, that electrical components of the system be exchanged and / or the pin assignment changes, etc., so that a change in the configuration of the bridges in the contact carrier is necessary.

For this purpose, in an advantageous embodiment of the contact carrier against another contact carrier, which has the desired configuration, be exchanged with little effort.

In many cases, it is sufficient to configure the

Modify contact carrier as follows to change the operating state of the electrical system:

A. Release the contact carrier from a housing cover of a

connector;

B. Separating at least two parts of the contact carrier from each other;

C. removing and / or adding and / or repositioning at least one U-shaped contact pin out of / into the contact carrier;

D. assembling the at least two parts of the contact carrier;

E. Attach the contact carrier to the housing cover.

In particular, the method can subsequently further

Have method steps:

F. Closing the housing cover and thus an automatic

Producing an electrically conductive connection between at least two contact sockets by at least one arranged in the contact carrier U-shaped contact pin, and thereby

G. electrically conductive connection of at least two electrical

Components of the electrical system, wherein these components each electrically conductive with one of the at least two

Contact sockets are connected.

In this way, the operating state of the electrical system can be flexibly, inexpensively and extremely inexpensively changed so that For example, an escalator changes its direction of travel above, which represents an additional advantage of the contact carrier. In this case, no further component is required, but it will be arranged differently only with little manual effort, only the existing components.

1 shows a connector with a connector housing 1, which has a mounting housing 12 with a hinge 1 1 and a housing cover 10 pivotally supported thereon. Furthermore, the connector has an insulating body 2 with not visible in this illustration contact sockets 28, and a locking bracket 14 for locking the optionally closed housing cover 10 at its locking pin 104th

In the housing cover 10 is a two-part contact carrier 3rd

recorded, which consists of a here for clarity, not yet designated upper part 31 and lower part 32. In that

Contact carrier 3 are U-shaped contact pins 8, 8 ^' , 8 ^" arranged as electrical bridges, which also in this illustration

Clarity reasons are not yet designated.

The contact carrier 3 has two latching arms 321 at two opposite ends. The housing cover 10 has two

Counter-locking arms 101, at the free-standing ends latching hooks 103 are formed. At this snap hook 103 of the contact carrier 3 locked with its locking arms 321 and is held on the housing cover 10. The contact carrier also has an L-shaped

Polarization element 31 1, which when closing the

Housing cover 10 engages in a polarizing recess of the insulating body 2, wherein the polarization is formed by two polarizing webs limiting 21 1. At its opposite side of the insulating body has a centrally disposed polarizing web 21 1 in the wrong orientation of the contact body 3 relative to

Insulating body 2 prevents closing of the housing cover 10.

2a and 2b will show the upper part 31 and the lower part 32 of the contact carrier 3 with a view of their respective contact surface 314, 324. Opposite, they each have a plug-in region 315, 325, although the respective plug-in regions in this perspective, but referred to actually obscured by the upper 31 or lower part 32 and therefore are not visible.

The upper part 31 has a cuboidal basic shape with the L-shaped polarization element 31 1 formed laterally thereon. In its contact side 314, a first contact receptacle 316 in the form of an elongated recess is arranged, which is connected at its ends in each case by a passage opening 318 with the contact region 315.

Furthermore, the upper part 31 has near its ends

slot-shaped continuous positioning openings 319. The cross-section of the positioning openings 319 has two mutually opposite semicircles, which are connected by two short, straight sections. This special cross-sectional shape of the

Positioning holes 319 serve, as will be explained later, the so-called "game" of the contact carrier 3 with respect to the

Housing cover 10 as tolerance compensation. As a result, a slight tilting movement relative to the housing cover 10 is made possible when closing the housing cover 10. The lower part 32 has just such positioning holes 329, which when joined to the upper part 31 at the

Connect positioning holes 319.

Furthermore, the lower part 32 has four in its contact surface 324

Contact recordings 326 ^' , 326 ^" , namely three second

Contact receptacles 326 ^' and a third contact 326 ^" , at the ends also through openings 328 as a connection to

Plug-in area 325 of the lower part 32 are arranged. The third

Contact 326 ^" is shorter than the three second

Contacts 326 ^' .

In addition, the lower part 32 has further passage openings 322, which when joined to the upper part 31 directly to the

Connect through holes 318.

In addition to the two aforementioned locking arms 321 has the

Lower part 32 positioning recesses 327 which, with not shown in this illustration positioning pins 317 of the upper part 31 during assembly of the upper part 31 with the lower part 32nd

interact.

Figures 3a, b, c show a set of U-shaped contact pins 8, 8 ^' , 8 ^" for insertion into the contact carrier 3. To fill said bridge function, they are made of metal and bent to their U-shape.

This set of U-shaped contact pins 8, 8 ^' , 8 ^" is assembled by way of example for a specific bridge function and comprises three different embodiments of the U-shaped contact pins 8, 8 ^' , 8 ^" , namely a first contact pins 8, three second contact pins 8 ^' and a third contact pin 8 ^" . The U-shaped contact pins 8, 8 ^' , 8 ^" each have two mutually parallel plug-side end portions 81, 81 81 a perpendicular thereto extending central region 82, 82 ^' , 82 ^" and in between each a bending region 83, 83 ^' , 83 ^" naturally has a certain curvature.

As can easily be seen from the drawing, the different U-shaped contact pins 8, 8 ^' , 8 ^" differ from each other by the length of their middle region 83, 83 ^' , 83 ^" and / or the length of their plug-side end regions 81, 81 ^' , 81 ^" .

The first contact pin 8 shown in Fig. 3a has, compared to the other contact pins 8 ^' , 8 ^" relatively long plug-side end portions 81, because it is intended for use in the upper part 31, while the other contact pins 81 ^' , 81 ^" for use in Lower part 32 are provided.

The illustrated in Fig. 3b second contact pin 8 ^' has a

Central region 82 ^' which is shorter than the central region 82 of the first

Contact pins 8 and longer than the middle region 82 ^"of the third

Contact pins 8 ^" .

The illustrated in Fig. 3c third contact pin 8 ^" has a

Middle region 82 ^" , which is shorter than the central region 8 ^'of the other contact pins 8, 8 ^' .

Of course, another set of contact pins can be assembled in number and shape for another desired bridge function.

Figs. 4a, b, c show the contact carrier 3 together with the

Contact pins 8, 8 ^' , 8 ^" . FIG. 4a shows this arrangement in an exploded view. In this case, the upper part 31 and the lower part 32 are separate and each with the / arranged above and to be inserted therein U-shaped

Contact pin (s) 8, 8 ^' , 8 ^" shown.

It can easily be seen that the first contact element 8 is intended to be arranged with its central region 82 in the first contact receptacle 316. Furthermore, it will be appreciated that the second and third contact elements 8 ^' , 8 ^" are intended for having their respective center regions 82 ^' , 82 ^" in the second and third, respectively

Contacting 316 ^' , 316 ^" to be arranged.

In this illustration, two positioning pins 317 of the upper part 31 are still recognizable, of which only one is designated for reasons of clarity. The upper part 31 has two further symmetrically arranged such positioning pins 317, which are not visible in this illustration. But it is easy to imagine that these four

Positioning pins 317 in the assembly of the upper part 31 and the lower part 32 are inserted into the corresponding slightly funnel-shaped positioning recesses 327 of the lower part 32, to ensure the exact positioning of the assembled upper 31 and lower part 32.

Fig. 4b shows the upper part 31 and the lower part 32 in the process of mutual assembly. The second 8 ^' and third 8 ^"

Contact pins are already inserted in the base 32, ie their respective center regions 82 ^' , 82 ^" are in the second 326 ^' and third 326 ^"

Contacts arranged and their mating side

End portions 81 ^' , 81 ^" are indicated by the corresponding ones

Through holes 328 and the corresponding hollow cylindrical projections 323 of the plug portion 325 of the lower part 32 out. The first contact element 8 is just about to be inserted with its middle part 82 into the first contact seat 316 of the upper part 31. His plug-side end portions 81 are already through the

corresponding through holes 318 of the upper part 31 and are just about to enter the further through holes 322 of the

Bottom 32 to be plugged.

In Fig. 4c of the upper part 31 and lower part assembled contact carrier 3 with the inserted therein U-shaped

Contact pins 8, 8 ^' , 8 ^" shown

Positioning openings 319, 329 of the upper part 31 du of the lower part 32 to each other.

Fig. 4d shows the contact carrier 3 in a slightly modified

Execution. The upper part 31 has four passage bumps 310. The lower part 32 has four Rasteinbuchtungen 320, each with a Rastanformung 3201 arranged therein.

In addition, the contact carrier 3 has a cover 33. The cover 33 has a rectangular protective surface 334 and fastening tabs 331, which are integrally formed on the protective surface 334, and each have a latching window 330.

Fig. 4e shows the composite contact carrier 3 ^' . The cover 33 is arranged with its protective surface 334 on the upper part 31 and thereby covers the extending through the first contact 316 of the upper part 31, U-shaped contact pin 8. The fastening tabs 331 are guided by the Durchgangsbuchtungen 310 of the upper part 31, engage the Rasteinbuchtungen 320th of the lower part 32 and engage with their locking windows 330 on the Rastanformungen 3201 of the lower part 32. Thus, the lid 33 is attachable to the upper part 31 and the lower part 32 can be fastened. The previously mentioned U-shaped contact pin 8, which passes through the upper part 31, could, for example, in some applications a high electrical voltage. Although this would normally be safe because the contact carrier 3 is fastened simultaneously in the housing cover 10 and the contact pin 8 is thus not accessible. However, in the case of damage and / or incorrect operation, there could well be a risk of, for example, manual contact with this contact pin 8. This is in the contact carrier 3 ^' in the present

Execution by the electrically insulating protective surface 334 of the

Lid 33 safely avoided. In addition, the lid 33 can fix in this way both itself and the upper part 31 on the lower part 32. The lid 33 thus has a dual function, because it serves the mechanical attachment and also the electrical safety. In particular, the latter applies when the contact carrier 3 ^' in

assembled state is glued.

FIG. 5a shows this arrangement from the direction of the plug-in area 325. In this view, the oblong-shaped cross-sectional shape of FIG

Positioning opening 319 of the upper part 31 to recognize particularly well.

FIG. 5b shows the same article in cross section through a

Cross-sectional area A. Here, both the first 8 and a second 8 ^' U-shaped contact pin with the respective plug-side end portion 81, 81 ^' can be seen well.

Fig. 5c shows that with the corresponding U-shaped

Contact pins 8 ^' , 8 ^" equipped lower part 32 with a view of its contact surface 4. In this view, the slot-shaped cross-sectional shape of the positioning hole 329 of the lower part 32 can be seen particularly well. FIG. 5 d shows the same article in cross-section through a cross-sectional area B that runs through the third contact receptacle 326 ^" .

In Fig. 5e, the assembled lower part 32 is shown in a side view.

FIG. 6 a shows the housing cover 10 without the contact carrier 3.

As a result, its positioning pin 109 and its latching hooks 101 are particularly well seen with the locking pin 103 formed thereon. The positioning pins 109 have a cylindrical, i. circular in cross-section, section.

6b shows this housing cover 10 with the contact carrier 3 inserted therein with the U-shaped contact pins 8, 8 ^' , 8 ^" received therein as contact bridges

is configured while the cross section of the positioning pin 109 at least in its corresponding cylindrical portion is circular. The resulting game allows a slight tilting movement of the contact carrier 3 in or against the pivoting direction of the

Housing cover 10 as a tolerance compensation when opening and closing the housing cover 10th

From Fig. 6c, the advantage of such tolerance compensation can be seen. If the housing cover 10 is closed, i. on the

Attachment housing 12 is pivoted, then the plug-side ends 81 of the U-shaped contact pins 8 are inserted into the Buchsenausnehmungen 228 of Isolierköpers 2 and experienced there inevitably a

Longitudinal movement, which together with the simultaneous

Pivoting movement of the housing cover 10 would usually cause mechanical stresses. These are however due to the tolerance between the contact carrier 3 and the housing cover 10, namely by the slight tilting movement of the contact carrier 3 relative to the

Housing cover 10 avoided.

Figs. 6d and 6f show the same arrangement in a front view and a plan view.

FIG. 6f shows this arrangement with the housing cover closed in a lateral cross-section through the third contact receptacle 326 ^" of FIG

Contact carrier 32. Here, the contact sockets 28 are shown and designated for the first time. It can easily be seen that the third U-shaped contact pin 8 ^" connects two mutually opposite contact sockets 28 with each other in an electrically conductive manner.

Cable connection side, the contact sockets 28 may be connected, for example, to electrical components of an electrical system, whereby these components are thus shorted.

Now, if the third contact pin 8 ^" removed from the contact carrier, which is possible with little effort, this bridge is no longer available and the two said electrical components of the electrical system are no longer short-circuited even when the housing cover 10 is closed

Short circuit bridges remain in the contact carrier 3 and thus continue to short circuit other electrical components of the system. Thus, the operating state of the electrical system in a particular

be changed in a comfortable way and without the use of other components.

When closing the housing cover 10, the correct orientation between the Isolierköper 2 and the contact carrier 3 by the L-shaped polarizing element 31 1 and by at least one Polarization web 21 1 ^'of the insulator 2 guaranteed.

Although various aspects or features of the invention are shown in combination in the figures, it will be apparent to those skilled in the art, unless stated otherwise, that the combinations illustrated and discussed are not the only ones possible. In particular, corresponding units or feature complexes from different embodiments can be exchanged with one another.
