Description

The invention relates to a carrier system, in particular for electrical Components with at least one carrier element, the at least one outside part and comprises at least one insertable into the outer part. Such carrier systems are used, for example, in motor vehicles Making electrical connections. The carrier system as a carrier for electrical components required in the motor vehicle, e.g. B. Fuses or relays can be used.

It is the problem (object) on which the invention is based, a carrier to create system of the type mentioned that a safe together Setting the outer part and inner part in the simplest possible way equips and ver on the electrical contact elements in particular can be locked.

This object is achieved by the features of claim 1 and in particular in that the inner part between an output layer ge and a predetermined end position is movable relative to the outer part and at least one actuator for moving the inner part in front is seen, the inner part by means of the actuating element each other in at least two different directions relative to the The outer part is movable.  

According to the invention, the inner part can be made from the actuating element going in one direction from the starting position or the end position be moved while moving on, e.g. B. the final transfer tion of the inner part in the other position, along one of the first direction of movement distinguishing direction takes place.

This makes it possible, for example, to contact elements that are already at coupled in the starting position inner part with the inner part are initially moved to an intermediate position by moving the inner part bring. Starting from this intermediate position, the contact elements then by moving the inner part in the second direction in one End position are transferred in which the contact elements z. B. on Au Reach behind the outer part of the locking areas and on the carrier system are locked securely to prevent them from being pulled out.

In particular, such contact elements can initially only be used the inner part can be locked, thereby realizing an initial locking and then by moving the inner part to the end position can also be locked with the outer part, creating a second lock success is achieved.

The provision of the actuator for moving the inner part he enables a simple movement of the actuating element in a more complicated, one after the other in different directions Implement movement of the inner part. This makes one independent of carrier system easy to operate due to the movement of the inner part fen.  

Furthermore, the actuating element can also serve the respective display the state of the carrier system. At the position of the actuator supply element can be read whether the inner part is in its Starting position, in its end position or in an intermediate position.

According to a preferred embodiment of the invention, they run to at least two directions of movement of the inner part approximately perpendicular to one another at the. Especially when the inner part and the outer part are in shape flat cuboid elements are provided, can with their Flat sides of parts aligned in parallel at substantially constant Distance can be shifted against each other. Then you can at the parts then in a relay running perpendicular to the flat sides tiv movement to be moved towards each other to the final to produce the assembled state.

According to a preferred variant, the actuating element is for moving towards the inner part at least essentially only in one direction moveable. Such a design of the actuating element enables it, by means of a simple, straight-line motion sequence the actuator from the starting position to the end position and around swept to move. This makes the carrier system particularly light serviceable.

According to a further preferred embodiment of the invention, Actuating element at least one particularly groove-like recess formed on which the actuating element together with the inner part affects and determines the course of the movement of the inner part is. This creates a possibility for forced guidance of the inside  partly created on the actuator with which the movement of the actuator tion element implemented in a well-defined movement of the inner part can be.

According to a further preferred embodiment of the invention Contact elements that are with the inner part in the starting position are outside a target position relative to the inner part, by moving can be brought into the end position in the target position. At the target position of the contact elements can be, for example, a position act in which the contact elements are locked on the inner part, where in this locking also be the first locking of the contact elements is drawn. The fact that according to this embodiment, the contact elements can be brought into the desired position by moving the inner part, it is ensured that the contact elements are ultimately both by the First locking with the inner part as well as through that in the preferred Variant of the invention provided second locking with the outer part are locked. It is advantageous here that the sequence of movements when closing assemble the carrier system regardless of the initial posi tion of the contact elements is relative to the inner part. Particularly advantageous is that by the sequence of movements when assembling the carrier y Stems not first locked contact elements moved relative to the inner part and brought into a first locking position with respect to the inner part become.

The invention thus both a safe initial adjustment and a secure second locking of the contact elements is also ensured.  

With the invention, the actuating element as well, at least an outer part and at least one inner part comprising carrier element each because under protection alone.

Further preferred embodiments of the invention are in the Un claims, the description and the drawing.

The invention will now be described by way of example with reference to the Drawing described. In this shows:

Fig. 1 shows the individual parts of a carrier system according to of one embodiment of the Erindung in a pre-assembly,

FIGS. 2a-4b different stages in assembling the Trägersy stems of FIG. 1, respectively in a plan view (Fig. 2b, 3b, 4b) and in a sectioned side view (Fig. 2a, 3a, 4a) along the dotted line in Fig. 2b, 3b and 4b, and

FIGS. 5a-7b representations corresponding to Figs. 2a-4b at the beginning au ßerhalb a target position located contact elements.

The carrier system shown in Fig. 1 comprises an outer part 10 , an inner part 12 and a U-shaped actuating element 20th The outer part 10 serving here as a lower part is designed as a cuboid open on one side and thus has a receiving space into which the inner part 12 serving here as an upper part can be inserted. Such a carrier system is also referred to as a top loader, here the outer part 10 serves as a carrier for the inner part 12 and the inner part 12 in turn as a carrier for z. B. can serve electrical components.

Furthermore, three contact elements 31 , 32 , 33 are shown by way of example in FIG. 1, which - as will be explained in more detail below - through openings 52 formed in the outer part 10 into the interior of the outer part 10 and into corresponding openings 50 of the inner part 12 are pluggable. The thereby arranged in a predetermined manner contact elements 31 , 32 , 33 can serve for the electrical connection with electrical components or modules which are placed on the inner part 12 from above. This can be, for example, fuses or relays that are used in motor vehicles in the.

The openings 52 and 50 formed in the outer part 10 and inner part 12 are each arranged in groups in the same way as is indicated by the dashed lines in FIG. 1 by way of example.

In the short side walls of the outer part 10 in the Eckbe rich passages 14 , 15 are formed, through which the legs 22 of the U-shaped actuating element 20 can be inserted, which is held by a user on a connecting the two legs 22 handle portion 24 becomes. The in the outer part 10 a slidable and thus serving as a mechanical slide actuating element 20 is cut at the free ends of the legs 22 with elongated from 25 , so that two elastically deformable sections are available. One of these two sections serves as a Rastab section 27 and is provided with a detent 26 arranged at its free end. This enables the actuator 20 in function of its depth of insertion with the passageways 15 upwardly bounding webs 41, 42 are latched and 43rd In each of the webs 41 , 42 , 43 corresponding positions, the actuating element 20 is thus held captive on the outer part 10 .

The passages 14 are each delimited at the top by a web 44 .

The legs 22 of the actuating element 20 are provided on their mutually facing inner sides with groove-like recesses 16 . The depth of the cutouts 16 corresponds approximately to half the thickness of the legs 22 . The purpose and design of the cooperating with cylindrical projections 18 on the inner part 12 and serving as a positive guide for the projections 18 and thus for the inner part 12 recesses 16 is explained in more detail below.

In the area of the passages 15 , the receiving space of the outer part 10 has a reduced width. Here, the inner part 12 is adapted by recesses 13 designed accordingly. Furthermore, 10 parallelepiped-shaped positioning sections 45 are provided on the bottom inside the outer part, which in the assembled state of the carrier system fit into corresponding recesses 11 of the inner part 12 . Another bottom-side, elongated positioning section 46 is provided centrally on the side wall of the outer part 10 delimiting the passages 14 . The correspondingly designed area of the inner part 12 cannot be seen in the illustration in FIG. 1.

FIGS. 2a and 2b show the composite carrier system in an initial position. The inner part 12, which is in its starting position, is inserted into the receiving space of the outer part 10 , but it still projects beyond its side walls. With its cylindrical projections 18 , the inner part 12 engages in a first region 17 of the savings 16 and thus lies on the legs 22 of the actuating element 20 .

Bulges 30 narrow the cutouts 16 each such that the inner part 12 with its projections 18 can be clipped into the cutouts 16 and can thus be locked with the actuating element 20 . In this way, the inner part 12 is held captively on the actuating element 20 in the pre-assembly state.

The first region 17 of the recesses 16 runs parallel to the longitudinal extension of the legs 22 - and thus parallel to a direction of insertion 5 of the actuating element 20 - up to a constriction, which is reduced by a width of the recess 16 , approximately, semicircularly curved web-shaped bulge 28 is formed. A second region 19 of the recesses 16 extends, starting from the narrowing at an acute angle obliquely to the insertion direction 5, away from that side of the leg 22 on which the recess 16 is open. In the position shown, the cutouts 16 thus each run obliquely in the direction of the outer part 10 .

The web-shaped bulges 28 are limited in areas by circular ge openings 29 , which allow the bulges 28 ela stically deform.

The diameter of the cylindrical projections 18 corresponds to the width of the groove-like recesses 16 . The length of the first region 17 of the cutouts 16 is in each case greater than the diameter of the projections 18 . In the starting position according to FIGS. 2a and 2b, however, the projections 18 cannot be moved in the direction of the second region 19 , since the inner part 12 lies against the right side wall of the outer part 10 in FIG. 2b.

As can be seen from Fig. 2b, the actuating element 20 is inserted so far into the outer part 10 that the locking lugs 26 engage the webs 43 behind. The actuating element 20 is thus already locked in the initial setting with the outer part 10 . In this position of the actuating element 20 , the inner part 12 can be used in the insertion direction E in the outer part 10 . Since the recesses 16 are each open on the outward-facing edge of the legs 22 , the projections 18 can each enter the first region 17 of the recesses 16 when the inner part 12 is inserted. To overcome the constrictions formed by the bulge 30 in the recesses 16 and thus for locking the inner part 12 on the actuating element 20 , a certain minimum force be required.

As can be seen in the left area of FIG. 2a, the contact elements 31 , 32 , 33 extend through the outer part 10 into the corresponding openings of the inner part 12 and are locked in this position with the inner part 12 . The contact elements 31 , 32 , 33 be each in their target position, in which they are held by this Erstverrie gelung on the inner part 12 .

In the initial position of the inner part 12 according to FIGS. 2a and 2b, the contact elements 31 , 32 , 33 can be guided past locking edges 34 , 35 and 36 when they are pushed through the outer part 10 . Without the first locking in the inner part 12 , the contact elements 31 , 32 , 33 could be pulled out again through the outer part 10 without resistance.

FIGS. 3a and 3b show an intermediate position of the carrier system, in which the actuating element 20 is inserted so far that the locking lugs 26 engage behind the next ridge 42. Due to the movement of the actuating element 20 , the projections 18 of the inner part 12 initially come into engagement with the web-shaped bulges 28 forming the constrictions in the cutouts 16 . With further movement of the actuating element 20 in the intermediate position shown in FIGS . 3a and 3b, the inner part 12 has been taken along with its projections 18 until it comes into abutment with the left-hand side wall of the outer part 10 in FIGS . 3a and 3b.

The stuck in the inner part 12 sections of the contact elements 31 , 32 , 33 have been moved by the movement of the inner part 12 over the locking edges 34 , 35 , 36 of the outer part 10 .

In the end position according to Fig. 4a and 4b, the actuator 20 corresponding to its maximum depth of insertion is in the outer part 10 inserted. The locking lugs 26 now engage behind the webs 41 . In the further insertion movement of the actuating element 20 starting from the intermediate position shown in FIGS . 3a and 3b, a certain minimum force has been overcome by the web-shaped bulges 28 have been elastically deformed. The minimum force to be overcome depends in particular on the choice of material and the dimensions of the legs 22 in the area of the constrictions and the dimensions of the projections 18 .

By overcoming the constrictions, the projections 18 could each reach the second area 19 of the recesses 16 and were accordingly guided in the course of the recesses 16 in the second area 19 . The inner part 12 , which could not move further in the direction of insertion S, has been moved through the oblique and thus a component in the direction of insertion E having the course of the recesses 16 in the direction of insertion E and thus towards the outer part 10 . In its end position shown in FIGS. 4a and 4b, the inner part rests against the bo of the receiving space of the outer part 10 . In this fully inserted state, the inner part 12 is flush with the side walls of the outer part 10 .

The contact elements 31 , 32 , 33 have also been moved by the movement of the inner part 12 in the direction of insertion E. In the inner part 12 stec kenden sections of the contact elements 31 , 32 , 33 are now in the end position immediately above the respective locking edge 34 , 35 , 36 , which ensure a second locking of the contact elements 31 , 32 , 33 on the carrier system.

The movement of the actuating element 20 which takes place only in the insertion direction S is thus implemented by the described configuration, in particular the recesses 16 , first in a direction parallel to the insertion direction S of the inner part 12 , ie the inner part 12 is carried along by the actuating element 20 . Subsequently, the movement of the actuating element 20 which continues in the insertion direction S is converted into a movement of the inner part 12 which runs exclusively in the insertion direction E and thus perpendicular to the insertion direction S. The inserted in the inner part 12 contact elements 31 , 32 , 33 are first brought from an initial position in which they are unaffected by the locking edges 34 , 35 , 36 of the outer part 10 in an intermediate position, which corresponds to the end position of the carrier system, as the contact elements 31 , 32 , 33 can no longer be pulled past the locking edges 34 , 35 , 36 through the outer part 10 .

When the inner part 12 is in the end position, the contact elements 31 , 32 , 33 are not only locked by the locking edges 34 , 35 , 36 on the carrier element, but also are held immovably with respect to the direction of insertion E and are thus positioned in a defined position.

While the locking of the contact elements 31 , 32 , 33 by the locking edges 34 , 35 , 36 represents a second locking element for the contact elements 31 , 32 , 33 , in the end position of the inner part 12 the contact elements 31 , 32 , 33 are also on the inner part 12 locked first.

As will be explained below in connection with FIGS. 5a to 7b, such contact elements, which are initially not in the desired position with respect to the inner part 12 and are thus not yet locked to the inner part 12 , can be moved by the movement of the inner part 12 relative to the outer part 10 are pressed into the first locking of the inner part 12 .

The first locking of these contact elements takes place according to the invention tomato.

By pulling the actuating element 20 out of the outer part 10 , the above-described movement of the inner part 12 takes place in the reverse order. The inner part 12 is thus first raised against the direction of insertion E and then entrained by the constrictions formed by the bulges 28 in the recesses 16 by the actuating element 20 moving counter to the insertion direction S.

Before reaching the starting position according to FIGS. 2a and 2b, a minimum force must again be applied to overcome the constrictions via the actuating element 20 . Finally, in the starting position, the second locking of the contact elements 31 , 32 , 33 on the outer part 10 is lifted up and the contact elements 31 , 32 , 33 can - after the first locking has been canceled by means of a suitable unlocking tool - past the locking edges 34 , 35 , 36 from the outer part 10 can be pulled out.

By how far the actuating element 20 is in the outer part 10 is inserted, can be read, in which position the carrier is system. A simple and reliable visual identification of the locking state of the carrier system is made possible in this way.

FIGS. 5a to 7b differs from the Fig. 2a to 4b respectively by the position of two of the three contact members 31, 32, 33 relative to the inner part 12. For reasons of clarity, not all reference numerals have been drawn in FIGS. 5a to 7b.

From Fig. 5a it can be seen that the contact elements 32 and 33 are not fully inserted into the inner part 12 and are therefore not in their desired position. In contrast to the contact element 31 on the left in FIG. 5 a, the contact elements 32 , 33 have not been initially locked. The production of a perfect final Verrie gelung also the contact elements 32 , 33 on the carrier system is not affected. As FIGS. 6a and 6b show, the movement of the inner part 12 into the intermediate position according to FIGS . 3a and 3b is in fact easily possible, since the contact elements 32 , 33 can also be moved over the corresponding locking edges 35 , 36 .

As FIGS. 7a and 7b show, during the subsequent movement of the inner part 12 in the direction of insertion E and thus into the end position according to FIGS . 4a and 4b, the contact elements 32 , 33 finally also reach the desired position with respect to the inner part 12 , since the movement of the contact elements 32, 33 of the inner part 12 is stopped by the locking edges 35, 36 before reaching the final position and the contact elements 32, 33 are thus pushed further into the inner part 12 inside.

In the carrier system according to the invention it is consequently ensured that inadvertently improperly pre-positioned and thus not initially locked contact elements in the finally assembled state are locked to the carrier system both by a correct first locking with the inner part 12 and by a correct second locking with the outer part 10 . According to the invention, the movement of the actuating element 20 for transferring the inner part 12 from the starting position into the end position is independent of whether the contact elements are properly pre-positioned or locked. A time-consuming check of the pre-positioning of the contact elements, ie the troubleshooting for individual contact elements that are not properly locked on the inner part 12 , is therefore not necessary. The assembly of the carrier system according to the invention is thus considerably simplified and, in particular, more reliable, since errors caused by improper prepositioning are automatically avoided.

In principle, such forced guidance is also possible according to the invention Lich, in which by actuating the actuating element in succession movements in more than two different directions of the inner part are forced.
