Description

The invention relates to a fuse carrier, in which a current bridge is added and adapted to receive flat fuses, as used in vehicles. The invention is thus preferably adapted for use in a vehicle, in particular a motor vehicle. The fuse carrier can be used in a fuse box or for a motor vehicle or be.

From the DE 203 16 994 U1 a fuse box for receiving a current bridge is known in which a formed on the current bridge crimping approach can be covered by a connectable to the fuse carrier and / or a secondary lock current bridge cover. For this purpose, the power bridge cover locks with locking lugs of the secondary lock or the fuse carrier. The fuse carrier is adapted to accept ATO fuses.

From the US 4,772,759 A and the DE 692 14 493 T2 are fuse carrier for receiving two-pole flat fuses known.

The so-called ATO fuses are known from the prior art ISO 8820-3: 2010 Form C known, which are pluggable in a fuse carrier of a motor vehicle. Such ATO fuses have a flat housing into which a fuse-link stamped from a plate-shaped material is inserted, the fuse link having two contact tongues projecting from the housing and a fuse section located in the housing, the fuse section electrically connecting the contact tongues. If an inadmissibly high power flows through the fuse, part of the fuse section burns, causing the fuse to open the circuit. For each fusion section a fuse is provided. As the number of electrical consumers in modern motor vehicles increases, so does the number of fuses required. Consequently, multiple fuses also require more space, with space in motor vehicles being in short supply. To counter this problem, so-called mini-fuses have been after ISO 8820-3: 2010 Form F, which are smaller in size, allowing more fuses to be placed in the same space.

Other ways to accommodate multiple melting sections on the same space, are in the publications EP 1 211 709 A2 . EP 0 967 627 B1 . DE 10 2008 049 101 A1 and JP 07 105 826 A disclosed. Fuses are shown which have more than two contact tongues and at least two fusion sections. These fuses are, however, custom-made, which differ significantly from the dimensions of known ATO fuses, whereby the fuses provided for the fuses have complicated geometries and require a lot of space.

It is therefore an object of the invention to provide a fuse carrier, the busbar is simple and yet stable mountable. It is a further object of the invention to provide a fuse carrier which has a compact design and yet is safe to handle.

The objects are achieved by the subject matter of claim 1. Advantageous further developments emerge from the dependent claims, the description and the figures.

The invention is based on a fuse carrier comprising a current bridge, which can be used in a vehicle, in particular a motor vehicle. The fuse carrier can have at least one first receiving compartment, in which at least one current bridge according to the invention is arranged, and at least one second receiving compartment, which is adapted to receive a single contact. The fuse carrier further comprises at least one, preferably a plurality of slots for a flat fuse, wherein each slot a pair of contact legs of the current bridge and a second receptacle or a pair of contact legs of a single contact, which is arranged in the second receptacle can be assigned. When inserting the fuse plug, which has at least two contact tongues, a contact tongue is inserted into the contact slot of the current bridge and the other contact tongue in the contact slot of the single contact, whereby the current bridge is electrically connected to the single contact.

The first receiving compartment can preferably be oblong or / and slot-shaped, wherein the flat security can be arranged approximately perpendicular to the first receiving compartment. The fuse carrier can, for. B. record a further current bridge in the at least one first receiving compartment, such. B. the same or another first storage compartment. The particular elongated current bridges can be arranged in alignment with each other in the fuse carrier.

The fuse carrier is not limited to flat fuses with two contact tongues (2-pin flat fuses), but the fuse carrier can be adapted, flat fuses with more than two, such. B. three (3-pin flat fuses) or even more contact tongues record. In particular, the fuse carrier at least a third receiving compartment for receiving a Single contacts have, each slot can be assigned in addition to a third receiving compartment. In this case, a flat fuse provided with three contact tongues can be inserted into the slot. In the at least one third receiving compartment, a single contact can be arranged. It is preferred that each slot the contact leg pair of current bridge between the second and third receiving compartment or between the arranged in the second and third receiving compartment contacts is arranged.

The current bridge may have a plurality of contact leg pairs, which are electrically connected and fed via a feed line.

A single contact may have a single pair of contact legs, with an electrical line, such. B. connected to a cable that leads to a consumer. In each case a single individual contact can be arranged in the second and / or third receiving compartment. Preferably, the fuse carrier comprises a plurality of second receiving compartments and a plurality of third receiving compartments.

The fuse carrier further comprises at least one slot which is configured such that it can receive a flat fuse, in particular a flat fuse as described herein. Preferably, the fuse carrier has a plurality of such slots, wherein a flat fuse can be arranged in each of these slots.

Each slot is assigned at least a part of the first receiving compartment, one of the at least one second receiving compartment and optionally one of the at least third receiving compartment. The slots associated with the slot are located below the slot or in alignment with the slot. If individual contacts are arranged in the second and third receiving compartments and a current bridge is disposed in the first receiving compartment, three pairs of contact legs are located at each of the slots, namely two individual contact leg pairs and one contact leg pair of the current bridge.

Since the fuse carrier is preferably designed for receiving a fuse with three contact tongues, exactly three contact leg pairs are provided per slot. Nevertheless, the fuse holder can also be designed so that each slot several second and / or third receiving compartments are provided, wherein the fuse may have more than three contact tongues. In a fuse carrier for receiving a fuse with two contact tongues, each slot exactly two pairs of contact legs are provided.

The at least one slot may be disposed on a first side of the fuse carrier opposite to a second side. The fuse carrier can be designed such that from the second side, the current bridge in the first receiving compartment and the individual contacts in the second and third receiving compartment are plugged or plugged. The current bridge and the individual contacts are in each case plugged or plugged into the respective receiving compartments with their contact leg pairs ahead. This ensures that the contact leg pairs are arranged on the lying on the first side slot.

If a flat fuse is plugged into the slot, the first contact tongue between the legs of a pair of contact legs of the current bridge, the second contact tongue between the contact legs of the contact leg pair of arranged in the second receptacle individual contact and the optional third contact tongue between the contact legs of the contact leg pair of in the optional third Receptacle arranged arranged single contact. The fuse carrier can be integrated into the electrical system of a motor vehicle such that the current bridge is connected to a voltage source, wherein current can be branched to two different individual contacts by means of a 3-pole flat fuse, wherein the individual contacts are electrically connected to different consumers.

In preferred embodiments, the first receiving compartment is arranged between the second and third receiving compartment. As a result, flat fuses can be integrated into the fuse carrier, the first contact tongue between the second and third contact tongue is arranged.

The first receiving compartment may be elongate, in particular slot-shaped. The slot is preferably configured such that the flat fuse arranged in the slot is arranged transversely, in particular perpendicular to the first receiving compartment or the current bridge. Thus, preferably, the slot be configured elongated, wherein the slot can be arranged transversely to the first receiving compartment or the current bridge.

The at least one slot can be adapted to the plug fuse, in particular its thickness and / or width, so that the plug fuse, in particular on its housing, is guided. Accordingly, the fuse carrier may have guides for the at least one slot. The slot is preferably designed so that it can accommodate a fuse plug whose housing, for example, have a width of 17-22 mm and / or a thickness of 2.5-6 mm or another dimension mentioned herein.

The fuse carrier comprises in preferred embodiments a locking device, in particular a so-called secondary locking. The secondary locking serves to reliably prevent removal of the individual contacts, which are secured, for example, with a primary locking mechanism, from the second and / or third compartment. If the individual contacts are arranged in the respective receiving compartment, they can be provisionally secured against being pulled out by means of a primary lock acting between the receiving compartment and the individual contact, which is formed, for example, as an elastic snapper on the receiving compartment or the individual contact. However, there is a risk that the individual contacts can still be pulled out of the receiving compartment when exerting an increased tensile force. The primary lock thus serves primarily as an assembly aid. The individual contacts are finally secured with the secondary interlock.

The locking device comprises a locking member for the at least one second receiving compartment, preferably for each second receiving compartment a locking member, and / or a locking member for the at least one third receiving compartment, preferably for each third receiving compartment a locking member. The locking device is movable from a release position in which the at least one locking member is arranged on or at, but not in its associated receiving compartment in a locking position in which the locking member is arranged in the receiving compartment associated therewith. The locking member may protrude in the locking position in its associated receiving compartment and reduce the cross section of the receiving compartment so that it prevents withdrawal of the individual contact from the receiving compartment. For example, a plurality of second receiving compartments may be provided, which are lined up along the first receiving compartment and spaced from each other with a latching measure. The locking device may have a plurality of locking members, which are arranged in a row and spaced with the latching measure. When moving the locking device from the release position into the locking position, preferably by half the catch, the locking members are moved into their associated second receiving compartments, where they get into locking engagement with the individual contacts. The same applies to the third storage compartments accordingly.

The at least one locking member may be disposed on a leg which extends in the direction in which the first and / or second receiving compartments are lined up. The fuse carrier may have a guide in which the locking device, in particular the leg of the locking device is linearly guided.

The fuse carrier can be configured so that the locking device axially locked in the locking position, whereby a movement of the locking device from the locking position is prevented in the release position.

In preferred embodiments, the fuse carrier may comprise a locking device for the at least one second receiving compartment and a locking device for the at least one third receiving compartment. The locking devices can be moved independently of each other. As a result, the at least one locking member for the at least one second receiving compartment can be moved independently of the at least one locking member for the at least one third receiving compartment into its associated receiving compartment, or / and vice versa.

In alternative, particularly preferred embodiments, the at least one locking member for the at least one second receiving compartment and the at least one locking member for the at least one third receiving compartment are formed on the locking device such that the locking members are movable together when the locking device from the release position to the locking position is moved. In particular, the at least one locking member for the at least one second receiving compartment and the at least one locking member for the at least one third receiving compartment axially fixed, such. B. by means of an integrally formed locking device.

Preferably, the first receiving compartment is arranged between the guide for the locking device for the at least one second receiving compartment and the guide for the locking device for the at least one third receiving compartment. The guide for the locking device for the at least one second receiving compartment is preferably arranged between the at least one second and the at least one first receiving compartment. For example, the locking device for the at least one third receiving compartment is arranged between the at least one first receiving compartment and the at least one third receiving compartment.

Another aspect of the invention relates to a fuse box or for a motor vehicle, wherein in the fuse box a plurality of fuse carriers, each having at least one slot for a fuse, are arranged. Of the fuse holders, at least one fuse carrier is so configured as described herein. At least one flat fuse described herein can be arranged or arranged at the slot of the fuse carrier described herein.

The fuse carrier can, for. B. be designed so that it can be snapped form-fitting with the fuse box.

A preferred current bridge comprises, as stated, at least one pair of contact legs, preferably a plurality of pairs of contact legs, the pair of contact legs having a first contact leg and a second contact leg. Between the contact legs, a contact slot for receiving a contact tongue to be connected, for example a flat fuse, is preferably formed. The contact legs are in particular designed so that the contact legs can pinch the contact tongue.

Preferably, the current bridge in the fuse carrier, in particular the first receiving compartment is inserted and locked with the fuse carrier, in particular with a housing of the fuse carrier, so that withdrawal of the current bridge from the fuse carrier is prevented or blocked against the plug. The housing, which can form the receiving compartments, is preferably formed from an electrically non-conductive material, in particular plastic.

On the housing or the first receiving compartment of the fuse carrier, one or more first stop surfaces may be formed. The first stop surface may be formed on a projection or recess facing the current bridge. The Abragung or recess can z. B. may be formed on a web which separates two adjacent second or third receiving compartments from each other.

One or more second stop surfaces may be formed on the current bridge. The first stop surface and the second stop surface are flat, d. H. in a surface contact with each other, at least when trying to pull the current bridge out of the housing or the first receiving compartment opposite to the plugging direction. The first stop surface and the second stop surface may be arranged approximately parallel to each other. As a result of the fact that the first and second abutment surfaces abut one another flatly, an attempt is made to pull out the current bridge, which distributes the pressure exerted by the first surface on the second surface to the surface contact. Since the housing forming the first abutment surface is made of plastic and the current bridge is made of metal, there may be the risk that the first abutment surface will be damaged by the current bridge if it does not abut surface but only with one edge on the first abutment surface. This edge could cut off a portion of the first abutment surface, thereby reducing the force required to pull out the current bridge. Due to the flat system, the pull-out force is increased, whereby the fuse carrier is stable and yet easy to install.

The first stop surface preferably has in and the second stop surface preferably opposite to the insertion of the current bridge. The first and / or second stop surface may be transversely, in particular perpendicular to the insertion of the current bridge in the housing or arranged.

The second stop surface may be arranged on a tongue produced by stamping bending. This means that the at least one tongue is produced by punching in combination with a forming, such as a plate-shaped or sheet-shaped semi-finished product. The second stop surface may be disposed at the distal or free end or an end face of the tongue. The second stop surface may be a sectional area, the z. B. was produced when punching out the current bridge from the plate-shaped or sheet-shaped semi-finished product.

The tongue may, in preferred embodiments, in a window passing through the current bridge in thickness, with which the tongue z. B. is connected at least on one of its sides and otherwise free, arranged and / or designed to be flexible, so that it locks when inserting the current bridge in the housing with this, whereby the second stop surface snaps in front of the first stop surface or before first stop surface is arranged.

The tongue can have at least one curvature, preferably two curvatures, which are curved in opposite directions. With a first curvature, the tongue can extend away from the rest of the current bridge and with a second, opposite to the first curvature curvature, the tongue z. B. extend counter to the insertion. The second curvature is preferably located between the second stop surface and the first curvature.

The current bridge can have a fastening device for a flexible conductor, in particular a crimp neck or a soldering area or a welding area, with which the flexible conductor can be fastened to the current bridge. For example, the conductor of a cable can be materially connected to the current bridge, in particular soldered or welded or be. The flexible conductor is preferably enveloped by an insulator and exposed at the point where it is electrically connected to the current bridge. The Fastening device may be integrally formed on the current bridge. Generally preferred, the current bridge is in one piece.

The crimp neck, which may also be referred to as an electrical crimp connection, can grasp the flexible conductor non-positively and / or positively, and thereby establish the electrical contact between the flexible electrical conductor and the current bridge. In addition, the crimping approach can be materially connected, in particular by soldering or welding to the flexible conductor.

In addition to the fastening device for the flexible conductor, the current bridge can have a strain relief crimp connection, which grips the isolator of the cable in a force-locking and / or form-fitting manner. This prevents a tensile force exerted approximately on the cable mechanically overloading the electrical connection of the flexible conductor with the fastening device.

The fastening device for the flexible conductor can be damaged on the one hand by the adjoining cable of the individual contacts or on the other hand damage the cable of the individual contacts. The DE 203 16 994 U1 Proposes that the crimped connection with a current bridge cover, at the edge regions of various holding elements or Schnapplaschen are arranged, which serve to lock the power bridge cover with the locking lugs of the secondary locking or the fuse carrier to cover. For this purpose, an intermediate wall, which is arranged between two outer walls of the housing of the fuse carriers, needed. As a result, the fuse carrier is increased in terms of its width, whereby valuable space is lost.

On the fastening device, a cap, in particular a current bridge cover, be plugged or be, which is attached to the current bridge, in particular the fastening device, or the cable and covers the fastening device or surrounds. The cap thus advantageously separates the cables of the individual contacts of the fastening device, whereby damage to the cables or the fastening device is prevented. An intermediate wall as in the DE 203 16 994 U1 is therefore no longer absolutely necessary, since the cap is no longer attached to the housing but directly to the current bridge or the cable and thus the fuse carrier can be made more compact.

The cap is preferably made of an electrically non-conductive material, such as. As plastic, and / or an injection molded part.

Preferably, the plugged onto the attachment portion cap is secured against removal from the attachment portion or the current bridge or the cable characterized in that the cap is non-positively and / or positively connected to the attachment portion, the current bridge or the cable. By "secured" should be understood inhibited, which means that the deduction in principle still possible, but can be difficult. For example, the cap can only be frictionally locked, d. H. essentially be secured against friction by friction. Preferably, the cap can be positively secured against removal, including a snap connection between the attachment portion, the current bridge or the cable on the one hand and the cap on the other hand can exist. For example, at least one of current bridge and cap having a locking means which connects the cap form-fitting manner with the current bridge.

The attached to the current bridge cap can be designed so that the at least one second receiving compartment and the optional at least one third receiving compartment are not blocked by the cap. As a result, a single contact can be inserted into the at least one second receiving compartment and the at least one third receiving compartment, even if the cap is attached.

The housing of the fuse carrier can be two z. B. have approximately parallel first and second walls, between which the first, the second and the optional third receiving compartment are arranged. Between the walls, the part of the current bridge arranged from the first receiving compartment, in particular the fastening means, and particularly preferably the cap, can also be arranged or enclosed. The first and second walls can be pulled up in the plugging direction relative to the first, second and third storage compartments or protrude from the second side of the fuse carrier from the remaining housing or the second and third storage compartments.

A gap may be formed between one of the first and second walls and the cap, and preferably also between the other of the first and second walls and the cap. In this gap, the cables can be arranged or carried out by inserted in the second or third storage compartments individual contacts or be.

Particularly preferably, the cables of the individual contacts are guided on the same side of the fuse carrier or the housing, as the cable of the current bridge. The cables of the individual contacts can form a cable harness in which optionally the cable of the current bridge can be included.

The fuse carrier can be a z. B. plastic lid having the at least one second receiving compartment, the at least one third receiving compartment and preferably the current bridge and the cap z. B. on the second side of the fuse carrier. The lid can also cover the cables of the individual contacts.

The cover may be integrally formed with the housing or be a separate part of the housing. Preferably, the lid is positively connected to the housing of the fuse carrier, snapped in particular with the first and second side walls of the fuse carrier. After the lid is snapped to the housing, he sits firmly, d. H. essentially immovable on the housing. One of the lid and housing, a snap element, such. B. have a locking tab which snaps or snaps into the other from the lid and housing, preferably in addition to a pivot joint. The cover is snapped with the housing after the cables of the individual contacts are laid. Together with the housing, the lid may form a preferably lateral opening, from which the cable harness is led out. The opening may be formed or enclosed between the lid and the second and third storage compartments of the housing and between the side walls of the housing.

The cover may be connected to the housing via a pivot joint, in particular a hinge, whereby the cover is pivotable into the position in which it locks or snaps with the housing. The pivot axis of the pivot joint is preferably arranged transversely or perpendicular to the longitudinal direction of the first receiving compartment. The cover may be a separate part having a part of the pivot joint, and the housing may form another part of the pivot joint which is connectable to the pivotal part of the cover to form the pivot joint. The cover may alternatively be formed integrally with the housing and be pivotable, for example via a film hinge with respect to the housing. The film hinge is a thin-walled compound which is deformable or bendable and advantageously inexpensive to produce during injection molding of the lid with the housing.

The contact leg pair is associated with a connecting portion which connects the first contact leg and the second contact leg and protrude from which the first contact leg and the second contact leg. The connecting portion has a surface which is preferably arranged between the first and second contact legs. Preferably, the surface forms the end of the contact slot. This surface or end face may be a cut surface, the z. B. was produced during punching out of the current bridge from a plate-shaped semifinished product.

The first contact leg may have a first contact portion and the second contact leg may have a second contact portion. The preferably flat or flattened first and second contact portions may be arranged in a common plane. Between the first contact portion and the second contact portion of the contact slot for receiving the contact tongue to be connected is arranged. Preferably, the contact slot is narrowed in the region between the contact sections. The contact slot can be enclosed by a first, in particular flat contact surface, which is formed on the first contact section, and a second, in particular planar contact surface, which is formed on the second contact section. The contact surfaces may be parallel to each other or arranged so that the contact slot tapers towards the free end of the contact legs. The advantage of such a tapered contact slot is that the contact legs are pressed or pivoted a little apart when inserting the contact tongue in the contact slot, whereby the first and second contact surface occupy a mutually parallel position and thus can lie flat against the contact tongue. For example, the connection section associated with the contact limb pair and the first and second contact section may lie in a common plane.

In preferred embodiments, the contact legs of the at least one pair of contact legs on a deformed portion, which causes the contact leg pair associated with the connecting portion outside the plane in which the first contact portion and the second contact portion are arranged. From a perspective in front of the projecting end of the pair of contact legs and in the plane of the first and second contact portions facing the contact slot, the connecting portion is out of alignment with the area of the contact slot between the contact portions. In other words, appears the connecting portion or the end face for the observer or z. B. an optical test device not behind the contact slot, but for example offset it. This results in a better contrast when the slot width of the contact slots or the current bridge in a test arrangement are optically tested or measured.

In preferred embodiments, the first contact portion and the second contact portion or their common plane are parallel offset or angled with respect to a disposed between the connecting portion and the deformed portion portion of the first and second Contact legs and / or with respect to a bus bar, which forms the connecting portions or the one.

For example, the connecting portion formed on the busbar may lie in a plane together with the busbar. The distributor rail is preferably formed flattened. From the busbar, the contact leg pairs can protrude. For example, the sections of the first and second contact legs arranged between the connecting section and the deformed section may lie in a common plane, in particular also in a common plane with the busbar.

For example, angling of the first contact portion and the second contact portion may be created by means of a bend forming the deformed portion. The turn or bend can be less than 90 °, about 90 ° or more than 90 °.

The parallel offset of the first and second contact portions may be achieved by including a first turn in a first direction and a second turn in a second direction opposite to the first direction from the deformed portion. If the first and second turns are bent by the same amount, the result is a parallel offset of the first and second contact sections.

It is generally preferred that the first contact leg and the second contact leg or at least the first contact section and the second contact section are arranged mirror-inverted relative to one another, in particular around the contact slot formed between the contact legs.

The contact slot can be divided into several areas, such. B. in a region between the first and second contact portion and a portion between the connecting portion and the contact portions are divided. Preferably, the slot width in the region between the connecting portion and the contact portions is greater than the slot width in the region of the contact portions. In this way, it is advantageously achieved that the contact legs only engage in the contact tongue of the fuse in the area of the contact sections.

If the current bridge has a plurality of pairs of contact legs, it is preferable for a slot to be formed between adjacent pairs of contact legs, which slot is referred to below as a neighboring slot which is delimited on the front side by the distributor rail. The contact slot and the neighboring slot may have a slot depth. This slot depth is the distance between the free end of a arranged on the contact slot or neighboring slot pair of contact legs and the frontal boundary of the contact or Nachbarschlitzes such. B. the busbar or the connecting portion. The slot depth of the contact slot may be larger, equal or preferably smaller than the slot depth of the neighboring slot. Due to the ratio of the slot depths of the contact slot and the neighboring slot, the spring characteristic of the first and second legs of a contact leg pair can be influenced in their common plane. However, the spring properties of the contact legs are also influenced by the deformed portion of the first and second contact leg. Due to the different slot depths, the influence of the deformed section on the spring properties can be compensated or compensated.

In preferred embodiments, the first contact portion and / or the second contact portion may have on its front and / or rear surface a local injection transverse to the plane in which the first and second contact portions are located. By means of these local indentations, the slot width of the contact slot narrowed in the region of the first and second contact sections can be produced. It will be supplementary to this DE 299 22 831 U1 in which such local indentations are shown. The local embossment shown in this publication causes due to their geometric center within the contact slot that the contact surfaces are thinner compared to the thickness of the material of the leg. This reduces the surface with which the contact surface on the contact tongue of the fuse can be applied, whereby the electrical resistance can increase.

In order to avoid this disadvantage, the local injection of the current bridge according to the invention may be pocket-shaped. Since the side wall extending around the bottom of the pocket has a closed contour, the press-fit on the one hand causes a narrowing of the contact slot and on the other hand that the contact surface of the contact slot with respect to the thickness of the first and / or second contact leg is not substantially thinner, but preferably has the same thickness.

The at least one local pocket-shaped press-in can in particular have an elongate and preferably also curved shape.

In particular, the geometric center of the at least one press-in can lie outside the contact slot. For example, the first contact limb may have a local injection on its front and / or rear side. Alternatively or additionally, this also applies to the second contact leg.

In particular, the elongated curved pocket-shaped press-in can be shaped concave or convex in the direction of the contact slot. If the pocket is shaped convexly toward the contact slot, a stronger deformation of the contact slot in its central area results. If the press-in to the contact slot is convex, the result is a greater deformation of the contact slot in its outer regions. In principle, the local embossment can also be straight, whereby certain deformation properties are achieved with respect to the contact slot.

A preferred electrical flat fuse, in particular plug-in fuse for use in a vehicle, in particular a motor vehicle, comprises a fuse link made of an electrically conductive material, in particular metal, and a housing made of electrically non-conductive material, which at least partially surrounds the fuse link. The fuse link can be made of a plate-shaped semi-finished product such. B. punched out of a metal sheet. For example, the metal may be zinc or a zinc based alloy. The fuse link is preferably in one piece. The preferably flat housing may have a greater width than thickness or length.

The fuse link comprises a first contact tongue and a second contact tongue (2-pole blade fuse) and optionally a third contact tongue (3-pole blade fuse), wherein the fuse link may have additional contact tongues in addition to these contact tongues. Preferably, however, the fuse link only has a first and second and optionally third contact tongue. The particular flat contact tongues can be arranged in a common plane. That is to say, in particular, that the contact tongues which are thin in relation to their length and width can be arranged with their length and width parallel to and in the common plane. The thickness of the reeds may be less than 1.5 or 1 mm. The thickness may for example be between 0.5 to 1 mm. The first, second and optional third contact tongue, in particular all the contact tongues of the fuse link protrude from a same side of the housing preferably parallel to each other. The contact tongues can protrude equidistant from the housing. Incidentally, the fuse link is enclosed by the housing, so that only the contact tongues of the fuse link are arranged outside the housing. The contact tongues may protrude, for example, up to 15 or 20 mm, preferably between 5 and 15 or 5 and 10 mm from the housing.

The fuse link furthermore has a first melting section and, in the case of a 3-pole flat fuse, a second melting section, wherein the melting section electrically conductively connects the first contact tongue to the second contact tongue and the second melting section electrically conductively connects the first contact tongue to the third contact tongue. In particular, the first melting section and the second melting section can branch off from one another independently of the first contact tongue. Advantageously, current can be supplied to the blade fuse at the first contact tongue and removed from the blade fuse at the second and third contact tongues. The first melting section can burn independently of the second melting section, and vice versa.

The fuse is preferably designed for use at rated voltages in the low voltage range, in particular less than 100 V, such as. B. 58, 32, 24, 12 or 6 V.

Preferably, the first contact tongue is wider than the second and / or third contact tongue. Since it is preferred to introduce the current via the first contact tongue to the flat fuse, it is advantageous to design the first contact tongue so that it can withstand a higher electrical power than the second or third contact tongue. The broader first contact tongue reduces the heat development in the flat fuse. Since the second and third contact tongues are narrower than the first contact tongue, the flat fuse can be kept small in width. If all contact tongues had the same width, either the first contact tongue would be undersized or the second and third contact tongue would be oversized, which would result in either a high level of heat generation or a space-consuming design.

In preferred embodiments, at least one of the second and third contact tongues may be arranged next to or directly adjacent to the first contact tongue. In particular, a second and third contact tongue can be arranged between the other of the second and third contact tongues and the first contact tongue. Preferably, however, the first contact tongue between the second and third contact tongue is arranged.

The first melting section and the second melting section are preferably flat and / or flat, and in particular may be arranged completely in the same plane as the contact tongues. This allows a very compact, d. H. flat design of the fuse.

The first and / or second melting section can be approximately the same thickness as the contact tongues or be thinner than the reeds. The melting sections can, for. B. have different metallurgical properties than the contact tongues. This can be z. B. be achieved in that the semi-finished product from which the fuse link is punched, removed at the intended location for the melting sections and optionally filled with another metal or metal alloy. The removal can z. B. done by grinding or milling.

In particular, the section which is very thin compared to the width of the contact tongues is referred to as the melting section. When the melting section burns, it is not necessary for the entire melting section to melt but only a part thereof.

Preferably, at least one of the first and second melting section forms the end of the fuse link opposite the projecting end of the fuse link. The first and / or second fusing portion may open to the end or end face of the first contact tongue, which is opposite to the projecting end of the first contact tongue. The first fusion portion may open to the end or the end face of the second contact tongue, which is opposite to the projecting end of the second contact tongue. The second fusion portion may open to the end or the end face of the third contact tongue, which is opposite to the projecting end of the third contact tongue. This allows the reeds closer, d. H. arrange with a smaller distance from each other, whereby the width of the flat fuse can be kept low. At the same time, there is sufficient room to match the geometry of the fusion section to obtain the desired melting properties for the fusion section.

Alternatively and preferably, the first contact tongue can form the end of the fuse link opposite the projecting end. Alternatively or additionally, the first melting section and / or the second melting section can open on at least one longitudinal side of the first contact tongue. In particular, the first melting section to a first, z. B. facing the second contact tongue longitudinal side and the second melting section to a second, the first opposite, z. B. which open to the third contact tongue longitudinal side. The first fusion portion may open to the end or the end face of the second contact tongue, which is opposite to the projecting end of the second contact tongue. The second fusion portion may open to the end or the end face of the third contact tongue, which is opposite to the projecting end of the third contact tongue.

Further alternatively and preferably, at least one of the second and third contact tongues may form the end of the fuse link opposite the projecting end. Alternatively or additionally, the first and / or second melting portion may open at the end or end face of the first contact tongue, which is opposite to the projecting end of the first contact tongue. In particular, the first melting section to a, z. B. pointing to the first contact tongue longitudinal side of the second contact tongue and / or the second melting section to a, z. B. which open to the first contact tongue longitudinal side of the third contact tongue.

The alternatives also allow the contact tongues to be arranged close to each other and room for the adaptation of the geometry of the melting sections.

The fuse link is preferably mounted in the region of the contact tongues on the housing, which is arranged between the first or second melting section and the part of the contact tongue arranged outside the housing. For example, the first, second and third contact tabs may each have a recess into which the housing engages positively, such. B. a hole or a notch. The fuse link may be snapped in the housing or the housing may, for. B. thermally deformed to engage in the recess. For a snap, the housing may have a snap-action nose, which engages in the recess when inserting the fuse-link into the housing.

The fuse link can be inserted into or from the side of the housing from which the contact tongues protrude, or inserted into the housing from the side opposite to the side from which the contact tongues protrude. By inserting the fuse link over the side opposite to the side from which the contact tongues protrude, it is possible in a particularly simple way to avoid damaging the melting sections during assembly. By inserting the fuse link on the side from which protrude the contact tongues, the opposite side of the housing can be closed in particular with a lid integrally formed on the housing. The lid can during molding, such. B. mitgeformt in injection molding of the housing. As a result, a separate lid can be saved, which fewer parts must be handled during assembly of the fuse.

The housing may have on the corresponding side a slot-shaped opening through which the fuse link inserted, in particular is inserted or was. The housing or the part of the housing which surrounds or laterally surrounds the fuse insert, in particular the melting sections, is preferably in one piece. In contrast to flat fuses, which have two side of the fuse housing arranged housing halves, which surround the fuse link and which are material or positively connected during assembly, allows a one piece, molded in particular by molding or injection molding housing part, which encloses the fuse side that at the assembly of fewer parts must be handled. Since the flat fuses are mass products, this can save considerable costs.

The housing may have counter stops against which abut one or more stops formed on the fuse link or the contact tongues during insertion, whereby a defined position with respect to the housing is specified for the fuse link. Generally, at least one of first, second and third contact tongues may have a stop in the direction of insertion into which the fuse link is inserted into the housing, and the housing for the or each stop may have a corresponding counterpart stop. In particular, the first and / or the second and the third contact tongue can each have a stop which is arranged on the longitudinal side or on the end face opposite the projecting end. The stop may be arranged on the longitudinal side of the second and / or third contact tongue pointing to or from the first contact tongue or on the longitudinal side or sides of the first contact tongue.

Generally, the contact tongues can be approximately the same length. The length is composed of the part located in the housing and the protruding from the housing part of the contact tongue. Alternatively, the first contact tongue may be longer than the second and third contact tongue. This is particularly advantageous when the end face of the first contact tongue forms the stop or when the melting sections open onto the longitudinal side of the first contact tongue. Alternatively, the second contact tongue and the third contact tongue may be longer than the first contact tongue. This is particularly advantageous when the end faces of the second and third contact tongues each form a stop or when the melting sections open onto the longitudinal side of the second and third contact tongues.

The housing may, in preferred embodiments, be transparent or have openings whereby the first and second fused portions are inspectable. Thus it can be visually determined whether one of the melting sections has burned out. In particularly preferred embodiments, the first melting section and the second melting section are arranged in the housing so that they can be inspected over that side of the housing which is opposite to the side from which the contact tongues protrude. Fuses, such as B. in the EP 0 967 627 B1 are indicated, do not allow an inspection of this site, so that these fuses for inspection must be removed from the fuse carrier. In the advantageous development of the flat fuse does not necessarily need to be removed from the fuse carrier to determine whether one of the melting sections is burned.

In particular, the housing may be open or closed on the side opposite the side from which the contact tongues protrude. In particular, this side or the opening may be closed by means of a lid attached to the housing part which laterally encloses the fuse link or the fuse link. The lid can z. B. with the housing or the housing part form-fit, in particular snapped, or cohesively, in particular glued or welded, connected or, as described above, be formed on the housing. The lid and / or the housing are particularly preferably formed of a transparent material, which allows the inspection of the melting sections. Furthermore, the lid or the housing may be an indication of the properties of one or more fusion sections, such. For example, a color coding or an indication consisting of characters.

The lid may form the counter stop for the stop, in particular the front side of the first contact tongue or the second and third contact tongue. This is particularly advantageous when the lid is molded integrally from the housing.

In extension of the contact tongues, the cover per contact tongue may have a separate opening, which advantageously makes it possible with contact pins of a measuring device z. B. to determine the electrical resistance between the first and the second or the first and the third contact tongue. The housing may have a length in Abragungsrichtung the contact tongues, the z. B. is less than 28 mm, preferably less than 15 mm. Preferably, the length is smaller than the width of the housing transversely to the Abragungsrichtung of the contact tongues and larger than the thickness of the housing transverse to the Abragungsrichtung. Preferably, the width of the housing is larger, in particular at least a factor of 2.5 or 3 greater than the thickness. The thickness may be less than 12 mm or between 2.5 and 12 and the width may be less than 36 mm or between 9 and 36 mm.

Due to the compact design of the fuse and several melting sections per fuse, the number of melting sections can be increased with the same installation space, in particular doubled.

When trying the current bridge 10 from the first storage compartment 32 pull out the tongue 14d at the first stop surface 32a so that pulling out the current bridge 10 from the first storage compartment 32 is prevented.

The housing 31 of the fuse carrier 30 is preferably formed of plastic, while the current bridge 10 made of metal, eliminating the current bridge 10 a higher strength than the housing 31 having. Is the second stop surface 14e not parallel to the first stop surface 32a arranged ( 14 ), lies the tongue 14d not flat but linear with an edge on the stop surface 32a at. Through the edge of the tongue 14d can the stop surface 32a damaged or even cut off, leaving the current bridge 10 no longer safe in the first storage compartment 32 is held.

It is therefore advantageous, the second stop surface 14e approximately parallel to the first stop surface 32a to arrange, as it is in the 12 and 13 is indicated. This results in a flat support of the second stop surface instead of a line support 14e at the first stop surface 32a , Damage to the first stop surface 32a can thus be avoided.

Such a preferred arrangement may be in the arrangement 14 z. B. be achieved in that the stop surface 14e to the stop surface 32a adjusted so that the stop surface 14e parallel to the stop surface 32a is. Alternatively, the stop surface 32a to the stop surface 14e be adjusted so that the stop surface 32a parallel to the stop surface 14e is.

In the in the 12 and 13 shown particularly preferred variant is the stop surface 14e formed by the tongue 14d starting from the current bridge 10 curved away with a first curvature and with a second, the first curvature opposite curvature curved so far that the stop surface 14e approximately parallel to the first stop surface 32a or approximately perpendicular to the insertion of the current bridge 10 is. The tongue 14d out 13 is thus curved S-shaped in cross section.

To damage the cable 80 the individual contacts on the fastening device 15 is prevented, on the arranged in the first receiving compartment current bridge 10 a cap 60 put on which the fastening device 15 covers. The cap 60 is in this example directly at the current bridge 10 attached. Although a frictional connection between the current bridge 10 and the cap 60 is sufficient, at least one of the cap 60 and the current bridge 10 a locking means 63 . 14b have, alternatively or in addition to the frictional connection, a positive connection between the cap 60 and electricity bridge 10 which provides a stripping on the power bridge 10 attached cap 60 from the electricity bridge 10 prevented or at least complicated.

The cap 60 ( 7a to 7c ) comprises a slot-shaped section 61 in which z. B. the locking means 63 can be arranged. The cap 60 is with the slit-shaped section 61 on the current bridge 10 or whose distributor rail can be placed, so that it slit-shaped portion of a part of the current bridge 10 or the busbar 14 embraces. The distribution rail 14 can, as in 8th shown the locking means 14b exhibit. The cap 60 has a cover portion 62 on, the fastening device 15 covers. The cover section 62 is preferably wider than the slot-shaped portion 61 ,

The attachment section 15 includes a contact crimp 15b for making electrical contact with the conductor of the cable 70 and a strain relief crimp 15a that the isolation of the cable 70 embraces.

In the 11 and 15 becomes the fuse carrier 30 with an attached cap 60 shown, taking in the second and third storage compartments 33a . 33b no individual contacts are arranged yet. The housing 31 has two side walls 31a . 31b which is arranged so that they have the crimp neck 15 and preferably also the cap arranged thereon 60 border laterally. The side walls 31a and 31b protrude from a second side or bottom of the housing 31 from the second and third storage compartments 33a . 33b from. Between the side wall 31a and the cap 60 and the side wall 31b and the cap 60 each one gap is formed, as best of 15 is recognizable. The gap is sized so that all or part of the sidewall 31a and the cap 60 and the side wall 31b and the cap 60 arranged second and third storage compartments 33a . 33b can be equipped with individual contacts, even if the cap 60 on the current bridge 10 is attached. How best 10 recognizable are cables 80 the individual contacts in the gap between the cap 60 and the side walls 31a . 31b arranged.

The cables 80 the individual contacts form together with the cable 70 the current bridge 10 a cable harness, the side of the fuse carrier 30 is brought out as best of all 9 is apparent.

After the cables 80 the individual contacts in the fuse carrier 30 are laid, the lid is 50 on the case 31 put on, in particular unfolded or swung open. This pivoting movement allows a hinge 51 , which through the housing 31 and the lid 15 is formed on the side opposite to the side on which the cables 70 . 80 be led out of the fuse carrier. The lid 50 is form-fitting with the housing 31 connected, in particular locked. For this purpose, the lid 50 locking tabs 52 on, which engage in locking lugs, of the housing, in particular the housing walls 31a . 31b be formed ( 9 ). The locking lugs are on the outsides of the side walls 31a . 31b educated. The locking tabs 52 embrace the side walls 31a . 31b on the outside. The lid 50 is preferably formed of plastic.
