Description

The present invention relates to a printed circuit board holder, a use of a printed circuit board holder for locking a printed circuit board, a system comprising a printed circuit board holder and a printed circuit board, and a method for releasing a printed circuit board that is locked in a printed circuit board holder.

Conventional circuit board mounts are known as hardware of computer systems. Exemplary conventional printed circuit board holders are used as sockets for connecting main memory modules for main boards.

Printed circuit board holders for holding printed circuit boards in vehicles are subject to certain requirements which conventional printed circuit board holders, such as those known from computer systems, do not meet.

Circuit board holders for holding circuit boards in vehicles are subject to shocks and vibrations, in particular while a vehicle is being driven, which can lead to circuit boards being damaged, so that a possible replacement of the circuit boards becomes necessary. In addition, individual vehicle development places different, often conflicting requirements on hardware that is to be installed in a vehicle.

It is therefore the object of the present invention to provide a circuit board holder which enables a circuit board to be locked in a vibration-proof manner in a circuit board holder in a vehicle, facilitates the exchange of circuit boards, and furthermore meets the requirements of vehicle development.

The above-described object is achieved by the subject matter of the independent claims; preferred embodiments are the subject matter of the dependent claims.

• - einen langgestreckten Aufnahmekörper,
  • -- wobei der langgestreckte Aufnahmekörper eine Aufnahme zur Anordnung eines Kontaktabschnitts der Leiterplatte darin aufweist; und
• - zumindest eine elastisch verformbare Verriegelungsvorrichtung,
  • -- wobei die zumindest eine elastisch verformbare Verriegelungsvorrichtung einen Verriegelungsvorsprung aufweist, der konfiguriert ist in eine Verriegelungsausnehmung der Leiterplatte einzugreifen, so dass die Leiterplatte verriegelt ist.

One aspect of the invention relates to a circuit board holder for receiving a circuit board and for fixing the circuit board to a base circuit board in a vehicle, comprising:

• - an elongated receiving body,
  • - wherein the elongated receiving body has a receptacle for the arrangement of a contact section of the circuit board therein; and
• - at least one elastically deformable locking device,
  • - wherein the at least one elastically deformable locking device has a locking projection which is configured to engage in a locking recess of the circuit board, so that the circuit board is locked.

Advantageously, the circuit board holder, which in particular has at least one elastically deformable locking projection that is configured to engage in a locking recess of the circuit board, so that the circuit board is locked, that an elastically releasable locking of the circuit board in the circuit board holder is provided. In other words, the circuit board can be reversibly arranged in the circuit board holder and securely fixed and, in particular, exchanged in the event of a defect, without the circuit board holder having to be plastically deformed for this purpose. Consequently, the present circuit board holder provides a vibration-proof locking for a circuit board, which at the same time facilitates the exchange of a circuit board.

In exemplary embodiments, the circuit board holder can in particular have two elastically deformable locking devices, wherein the two elastically deformable locking devices can preferably be arranged opposite one another in the longitudinal direction. As a result, a printed circuit board can be locked on both sides in the printed circuit board holder, which enables an advantageously secure and vibration-proof arrangement or locking of the printed circuit board in the printed circuit board holder.

In alternative embodiments, the circuit board holder can have any number of elastically deformable locking devices.

The at least one elastically deformable locking device can in particular be arranged in an end region of the elongated receiving body or an end region of the receptacle.

In the following, various terms are used repeatedly, the understanding of which should be facilitated by the following definitions.

Elongated: The term elongated is mostly used with the term receiving body and indicates that the element referred to, in particular the receiving body, has an extension in the longitudinal direction which is significantly greater than its extension in the width and / or in the height direction. With respect to the elongated receiving body, this can be of a length which is about 20 to about 60 times as large as a width of the elongated receiving body or have a length which is about 5 to about 40 times as large as a height of the elongated receiving body.

Longitudinal direction: The longitudinal direction describes a direction in which the circuit board holder or the elongated receiving body has its longest extension. Furthermore, the longitudinal direction runs essentially parallel to a long edge of a contact section of a printed circuit board, which can be arranged in the receptacle of the elongated receptacle body, such as in the case of a main memory module.

Height direction: The height direction is generally perpendicular to the longitudinal direction and essentially corresponds to a normal to a base circuit board, in particular a normal to a base circuit board extending over a flat area. Furthermore, the height direction can essentially correspond to a direction in which the circuit board is pushed or plugged into the receptacle of the elongated receiving body.

Width direction: The width direction is generally essentially perpendicular to the length direction and the height direction. The width direction is used in the present application essentially to describe wall thicknesses, wall thicknesses or the like. The width direction can furthermore correspond to an edge of a contact section of a circuit board which extends along the short side.

The longitudinal direction, the height direction and the width direction do not have to correspond in particular to a length direction, a height direction and a width direction of a vehicle, but rather can be independent thereof.

The height direction, the width direction and the longitudinal direction can form a coordinate system, in particular a right system.

Vibration-proof: The term vibration-proof is mostly used here to characterize a connection, connection or fixation. Vibration-resistant describes that a connection, connection or fixation does not come off by itself in the event of vibrations and shocks in the normal range of applications and in a certain area beyond.

Vibration stable: The term vibration stable is mostly used here to characterize an element or component itself. Vibration stable describes that an element or component does not oscillate or vibrate by itself in the event of vibrations and shocks in the normal range of applications and in a certain range beyond.

Non-destructive detachable: A connection of two elements or components, the detachment of which causes the partial or complete destruction of at least one of the two elements or components that are detached from one another, cannot be detached non-destructively. The connection of two elements cannot be released non-destructively even if the use of solvents to dissolve the two elements from one another causes at least a negative impairment of the material properties or structure of at least one of the two elements. Examples of non-destructive detachable connections are adhesive connections, for example using adhesives, material connections that are produced, for example, by welding processes, mechanical connections that are produced, for example, by riveting two or more elements, and other connections that do not have the associated property of meet non-destructive solubility.

Base circuit board: Base circuit board means a circuit board or a PCB (printed circuit board) that serves as the basis for connection or fixing. The base circuit board can be any circuit board. Alternatively, the base circuit board can rather describe a base module which, among other things, serves to connect or fix additional circuit boards.

Elastically deformable / elastic deformation: Elastic deformability describes that an element or component designated with it can be elastically deformed, in other words, in particular, can be deformed in such a way that the element or component essentially completely or completely regains its geometry after the deformation has before the deformation. An elastic deformation is limited in that it describes a deformation, with essentially no or no plastic deformation occurring. An elastically deformed element can be essentially completely returned to an initial state.

In preferred embodiments of the circuit board holder, the at least one elastically deformable locking device can have a tool lead-through element with a tool opening and the circuit board holder can have a tool insertion element with an unlocking recess, the unlocking recess being arranged at a height from the tool opening, and wherein the elastically deformable locking device is configured to be when guiding a tool through the tool opening and into the To deform the unlocking recess elastically in such a way that the circuit board is unlocked, in other words, that the locking projection no longer engages in the locking recess of the circuit board.

The unlocking recess, which is arranged at a distance from the tool opening in the height direction, can in particular be arranged at a distance from the tool opening in the height direction of the elongated receiving body or the circuit board holder. The unlocking recess can be arranged, for example, in the vertical direction below the tool opening.

Advantageously, a tool lead-through element with a tool opening and a tool insertion element with an unlocking recess can provide a circuit board holder which enables a circuit board in the circuit board holder to be unlocked in a particularly user-friendly manner. A possibly necessary exchange of a printed circuit board can thus be simplified in that only one tool is required which is suitable for being passed through a tool opening and inserted into a tool opening. A screwdriver, a pen or, alternatively, any other special tool or general tool can serve as a tool.

In addition, the process essentially defined by means of the tool lead-through element and tool insertion element or by means of the tool opening and unlocking recess, which leads to an elastically deformable locking device being elastically deformed, can advantageously be automated, for example by a robot. In this way, for example, when a circuit board holder is fitted with a circuit board, a tool can be guided through the tool opening and into the unlocking recess by means of a robot arm, so that the elastically deformable locking device is elastically deformed, after which, for example, another robot arm arranges a circuit board in the circuit board holder can make. Furthermore, when replacing a circuit board or simply removing a circuit board from a circuit board holder, a tool can be guided through the tool opening and into the unlocking recess by means of a robot arm, so that the elastically deformable locking device is elastically deformed and the locking projection out of the locking recess of the circuit board moves, according to which, for example, another robot arm can remove and, if necessary, insert another or new circuit board in the circuit board holder. Thus, with the present circuit board holder by means of the arrangement of a tool lead-through element with a tool opening and a tool insertion element with an unlocking recess, an automated loading, exchange and removal of circuit boards in or from a circuit board holder can advantageously be made possible.

The tool opening can in particular extend with a continuous opening or a through hole along a tool opening axis of the tool lead-through element. Furthermore, the tool opening axis can in particular be parallel to the vertical direction of the elongated receiving body or the circuit board holder, but can also deviate therefrom.

Furthermore, in exemplary embodiments, the tool opening can in particular extend cylindrically along the tool opening axis. In alternative embodiments, the cross section of the tool opening can be configured as a polygon, in particular as a triangle, square, pentagon or hexagon. The diameter or cross section of the tool opening can in particular have a ratio in the range from about 1.01 to about 1.3 to the diameter or cross section of a tool that is passed through.

The unlocking recess can in particular be configured as a blind hole along an unlocking recess axis. In other words, the unlocking recess cannot be configured as a continuous opening, but rather have an unlocking recess base. An unlocking recess base can advantageously protect a base circuit board from damage by a tool during an unlocking process.

Alternatively, the unlocking recess can in particular be configured as a through hole. An unlocking recess which is configured as a through hole advantageously enables the unlocking recess to be configured as an additional means for fixing the circuit board holder to a base circuit board.

Furthermore, the unlocking recess axis can in particular be parallel to the height direction of the elongated receiving body or the circuit board holder. The unlocking recess axis can, however, also deviate from the height direction of the elongated receiving body.

Furthermore, in exemplary embodiments, the unlocking recess can in particular extend cylindrically along the unlocking recess axis. In alternative Embodiments, the unlocking recess in cross section can be configured as a polygon, in particular as a triangle, square, pentagon or hexagon.

The diameter or cross section of the unlocking recess can in particular have a ratio in the range from about 1.01 to about 1.3 to the diameter or cross section of the inserted tool. The ratio of the diameter or cross-section of the unlocking recess to the diameter or cross-section of the inserted tool influences the necessary extension of the tool insertion element in the height direction, since when the tool is inserted, depending on the diameter or cross-section ratio, the tool enforces a different one with progressive insertion into the unlocking recess Experiences inclination with respect to the unlocking recess axis.

On the one hand, a large diameter or cross-sectional ratio of the unlocking recess to the tool has the advantageous effect that the tool is easy to insert, so that it is easier to detach the circuit board from the circuit board holder.

On the other hand, a small diameter or cross-sectional ratio of the unlocking recess to the tool has the advantageous effect that the tool is inclined towards the unlocking recess axis over a small height of the tool insertion element and an elastic deformation can be applied to the elastically deformable locking device, so that a less material is required, and the production is thus simplified and cheaper.

In preferred embodiments of the circuit board holder, the tool opening of the tool lead-through element can have an essentially axial extension along a tool opening axis and the unlocking recess of the tool insertion element can have an essentially axial extension along an unlocking recess axis, the tool opening axis being different from the unlocking recess axis.

The tool opening, which extends essentially axially along a tool opening axis, and the unlocking recess, which extends essentially axially along an unlocking recess axis, the tool opening axis being different from the unlocking recess axis, advantageously enables elastic deformation of the elastically deformable locking device is ensured when passing a tool through the tool opening and then inserting the tool into the unlocking recess of the elastically deformable locking device.

In exemplary embodiments, the tool opening axis and the unlocking recess axis can be configured to be parallel to one another, skewed to one another, or to intersect at a certain point. If the tool opening axis and the unlocking recess axis are configured so that they intersect at a certain point, the point is preferably selected so that it is configured in the height direction below the edge of the unlocking recess at the top in the height direction in order to ensure elastic deformation of the elastically deformable locking device . The elastic deformation of the elastically deformable locking device advantageously leads to the locking projection being moved in a direction facing away from the receptacle or in a direction facing away from the locking recess of the circuit board, so that the circuit board is unlocked due to the elastic deformation of the elastically deformable locking device.

In preferred embodiments of the circuit board holder, the tool opening axis and the unlocking recess axis can be configured parallel to one another. Furthermore, in preferred embodiments, the unlocking recess axis and the tool opening axis can be spaced apart from one another at least in the longitudinal direction of the elongated receiving body.

In other words, in a locked state of the circuit board holder, a circuit board can be arranged or fixed in the receptacle, the locking projection of the elastically deformable locking device engaging in a locking recess of the circuit board. Furthermore, in a locked state of the circuit board holder, the tool opening axis and the unlocking recess axis can be configured parallel to one another. A locked state of the circuit board holder can be characterized in that the elastically deformable locking device is in a basic state, the elastically deformable locking device not having any elastic deformation or deflection.

For example, the tool opening axis and the unlocking recess axis can be essentially parallel to the height direction of the elongated receiving body.

Furthermore, by way of example, the tool opening axis and the unlocking recess axis can be configured at a distance from one another in the longitudinal direction of the elongated receiving body. In particular, the unlocking recess axis can be spaced apart from the tool opening axis in the longitudinal direction facing away from the receptacle of the elongated receptacle body.

For example, by having the tool opening axis parallel to the unlocking recess axis and the two axes being spaced apart from one another in the longitudinal direction, an unlocking movement of the locking projection from the locking recess of the circuit board can be ensured by guiding a tool through the tool opening and into the unlocking recess. In particular, the circuit board holder can be brought from a locked state to an unlocked state, with the elastically deformable locking device being elastically deformed in an unlocked state of the circuit board holder in such a way that the locking projection does not engage in the locking recess of the circuit board. In other words, the unlocked state of the circuit board holder can be characterized in that the elastically deformable locking device is in a deflected state, the elastically deformable locking device being elastically deformed or deflected in such a way that the locking projection does not engage in the locking recess of the circuit board. In other words, the unlocked state of the printed circuit board holder can be characterized in that a printed circuit board can be guided or removed from the receptacle of the printed circuit board holder, the locking projection not interfering with guiding or removing the printed circuit board from the receptacle. Likewise, an unlocked state of the circuit board holder can be characterized in that the elastically deformable locking device is elastically deformed in such a way that a circuit board can be inserted into the receptacle of the circuit board holder, the locking projection not interfering with the insertion.

Because the tool opening axis is for example parallel to the unlocking recess axis and the two axes are spaced apart from one another in the longitudinal direction, a targeted transition of the elastically deformable locking device from a basic state to a deflected state can advantageously be ensured. The ensured targeted transition from a basic state to a deflected state of the elastically deformable locking device by guiding a tool through the tool opening and into the unlocking recess, advantageously enables an unlocking movement of the locking projection from the locking recess of the circuit board.

In preferred embodiments of the printed circuit board holder, the tool insertion element can be configured more rigidly than the tool insertion element.

In other words, the tool insertion element can be more rigid than the tool insertion element with respect to a deflection in the longitudinal direction facing away from the receptacle of the elongated receptacle body. In particular, the tool insertion element can be more rigid with respect to a deflection in the longitudinal direction facing away from the receptacle of the elongated receptacle body than a deformation section of the elastically deformable locking device. A deformation section of the elastically deformable locking device can in particular be provided with a comparatively thin wall thickness measured in the longitudinal direction and in particular lie below a section on which the locking projection and tool lead-through element are arranged.

For example, the tool insertion element and the tool throughfeed element can be comparatively stiff with respect to a deformation section of the elastically deformable locking device, the deformation section being configured to deform essentially elastically when a tool is guided through the tool opening and into the relief recess, in particular to deform elastically more easily than the tool insertion element and the tool insertion element. In other words, the tool insertion element and the tool lead-through element can be comparatively stiffer than a deformation section of the elastically deformable locking device. The deformation section can, for example, be arranged in a region of the elastically deformable locking device which lies in the height direction between the elongated receiving body and the tool insertion element or locking projection. Furthermore, by way of example, the deformation section can be arranged in a region of the elastically deformable locking device which lies in the height direction between a fixing section of the circuit board holder and the tool insertion element or locking projection. The comparatively more rigid configuration of the tool insertion element and of the tool insertion element can in particular relate to a deflection in the longitudinal direction facing away from the receptacle. In other words, the comparatively more rigid configuration of the tool insertion element and of the tool insertion element can, in particular, relate to a bend in the longitudinal direction facing away from the receptacle with a bend axis which is in the Extending essentially along the width direction, relate. The deformation section can in particular have a wall thickness that is thin in sections and measured in the direction of deflection.

The fact that the tool insertion element is configured to be comparatively stiffer ensures that the elastically deformable locking device is elastically deformed, while the tool insertion element remains undeformed or is only subject to slight deformations, in particular elastic deformations.

The tool insertion element can be stiffened, for example, by an increased wall thickness.

In other exemplary embodiments, the tool insertion element can have a plurality of stiffening elements. By arranging stiffening elements on the tool insertion element in order to stiffen it, the tool insertion element and thus the circuit board holder can also be configured particularly suitable for injection molding by avoiding material accumulations, so that in turn a possible distortion can be reduced or avoided.

In preferred embodiments of the circuit board holder, the tool opening and / or the unlocking recess can be shaped with an essentially cylindrical inner wall.

A cylindrically shaped inner wall of the tool opening and / or the unlocking recess advantageously enables both round and polygonal tools to be used in order to be guided through the tool opening and into the unlocking recess.

In other exemplary embodiments, the tool opening and / or the unlocking recess can be shaped with a polygonal inner wall, so that an unlocking coding is provided for special tools or special tools, which prevents or at least makes it more difficult for non-skilled personnel to release or unlock the circuit board from the circuit board holder .

In preferred embodiments of the circuit board holder, the tool opening axis and the unlocking recess axis can be parallel to one another and spaced apart from one another in the longitudinal direction of the elongated receiving body.

In exemplary embodiments, the tool opening axis and the unlocking recess axis can be parallel to one another and provided with an unlocking distance in the longitudinal direction, which is approximately 1.1 to approximately 5.0 times, preferably approximately 2.5 times the extension in the longitudinal direction of the locking projection in FIG Locking recess corresponds.

This ensures that when the tool is passed through the tool opening and then inserted into the unlocking recess, a sufficiently large elastic deformation is applied to the elastically deformable locking device so that unlocking of the circuit board in the circuit board holder is ensured. In other words, based on the exemplary spacing of the tool opening axis from the unlocking recess axis, a transition of the elastically deformable locking device from the locking state to an unlocking state is advantageously ensured. In particular, spacings in the longitudinal direction of the parallel tool opening axis and unlocking recess axis, which are above approximately 2.0 in relation to the extent of the locking projection in the locking recess, allow a tool to be used with a tool diameter that is thin compared to a cross-sectional diameter of the tool opening. Furthermore, an extension ratio above about 2.0 enables the tool to be inserted only slightly into the unlocking recess in order to deform the elastically deformable locking device so elastically that the circuit board in the circuit board holder is unlocked.

In preferred embodiments of the circuit board holder, the tool insertion element can have a plurality of stiffening elements.

By arranging a plurality of stiffening elements on the tool insertion element, the tool insertion element is stiffened so that when a tool is passed through the tool opening and then the tool is inserted into the unlocking recess, the elastically deformable locking device is more easily elastically deformed than the tool insertion element. In particular, stiffening elements on the tool insertion element enable the elastically deformable locking device to be elastically deformed and the tool insertion element essentially not to be deformed when a tool is passed through the tool opening and then the tool is inserted into the unlocking recess. Stiffening elements which are arranged on the tool insertion element thus advantageously enable the tool insertion element to change its geometry retains or retains substantially over several unlocking processes.

In exemplary embodiments, a plurality of stiffening elements can be arranged on the tool insertion element, the stiffening elements extending essentially in the height direction.

Since stiffening elements of the plurality of stiffening elements extend essentially in the height direction, the tool insertion element can advantageously be stiffened against elastic deformation or deflection in the longitudinal direction. In particular, a plurality of stiffening elements which extend essentially in the height direction makes it possible for the tool insertion element not to be tilted or pivoted during an unlocking process or over several unlocking processes.

In exemplary embodiments, the tool insertion element can in particular have four stiffening elements. In alternative embodiments, the tool insertion element can have any number of stiffening elements, such as one, two, three, four, five, six, seven or eight stiffening elements.

In preferred embodiments of the circuit board holder, the elongated receiving body can have a first end and a second end in the longitudinal direction and the circuit board holder can have a first fixing section which is arranged at the first end of the elongated receiving body and a second fixing section which is arranged at the second end of the elongated receiving body is arranged, wherein an at least first fixing element can be fixed to the first fixing section in order to be fixed to the base circuit board, and at least a second fixing element can be fixed to the second fixing portion in order to be fixed to the base circuit board, the at least a tool insertion element can be arranged on at least one of the first fixing section and the second fixing section, and wherein the unlocking recess of the at least one tool insertion element is spaced apart in the longitudinal direction, facing away from the receptacle is arranged to the tool opening.

The longitudinally first end and second end of the elongated receiving body each represent a transition area between the elongated receiving body and the respective first and second fixing section. In other words, the first end and second end in the longitudinal direction of the elongated receiving body are an end area and not a geometrically defined location .

By arranging the at least one tool insertion element on at least one of the first fixing portion and the second fixing portion, the first and second fixing portion each being configured to be fixed by at least one fixing element on the base circuit board, the tool insertion element can be stabilized so that a more stable or trouble-free unlocking process is made possible.

Furthermore, during an unlocking process of the circuit board, with a tool being inserted into the unlocking recess of the tool insertion element, a force can be exerted from the tool via the tool insertion element directly on the fixing section, the fixing element attached to it and finally on the base circuit board. As a result, the force during an unlocking process is advantageously diverted via the base circuit board, in particular without running through the elongated receiving body, so that the possibility of damaging the circuit board is reduced.

In addition, the unlocking recess of the tool insertion element, which is arranged in the longitudinal direction facing away from the receptacle of the circuit board and at a distance from the tool opening, enables a tool to perform a lever action when it is passed through the tool opening and then inserted into the unlocking recess, with a center of rotation in the area of the unlocking recess and a direction of rotation in the longitudinal direction turned away from the recording, causes. As a result, a tool handle is moved away from the receptacle in the height direction during the lever operation, so that a detached or unlocked circuit board can be removed in the height direction.

In exemplary embodiments, the circuit board holder can have exactly two tool insertion elements and exactly two elastically deformable locking devices. For example, a tool insertion element can be arranged on the first fixing section and a further tool insertion element can be arranged on the second fixing section, so that exactly two tool insertion elements can be arranged opposite one another in the longitudinal direction. For example, an elastically deformable locking device can also be arranged in a region of the first end of the elongated receiving body and the other elastically deformable locking device can be arranged in a region of the second end of the elongated receiving body.

In alternative embodiments, the circuit board holder can have any number of tool insertion elements and one have any further number of elastically deformable locking devices.

In preferred embodiments of the circuit board holder, the locking projection can be configured flat on its underside.

Advantageously, a locking projection which is configured or designed with a flat underside makes it difficult or impossible for the printed circuit board to move or deflect independently in the vertical direction and out of the locked state. This is made possible by the fact that the flatly configured underside of the locking projection makes it difficult or impossible for the locking recess to slide off the locking projection in the vertical direction from bottom to top.

In exemplary embodiments, the bottom of the locking projection may be configured with an extension in a plane that is configured substantially parallel to the longitudinal direction and width direction.

In further exemplary embodiments, the underside of the locking projection can have a decreasing height along the extension into a locking recess of a circuit board, so that the locking projection is configured as an engaging tooth inclined downward in the height direction.

In further exemplary embodiments, the locking protrusion can be configured with any shape and / or inclination. In exemplary embodiments, a section of the locking projection facing the locking recess of the printed circuit board can comprise a material or be provided with a material which has a high coefficient of friction, such as an elastomer, for example.

In preferred embodiments of the printed circuit board holder, the receptacle can have a first receptacle end region and a second receptacle end region in the longitudinal direction, with at least one pair of positioning elements that are opposite in the width direction, in particular opposite in the width direction of the elongated receptacle body, being arranged on at least one of the first receptacle end region and the second receptacle end region each positioning element is provided with a positioning projection, the positioning projections of the positioning elements lying opposite one another in pairs, in particular the positioning elements lying opposite in the width direction, extending towards one another and forming a positioning gap in the width direction, and the positioning projections in a section with a cutting plane parallel to the height direction and the width direction are trapezoidal.

In other words, the positioning projections can be configured to extend from the respective positioning element towards a side surface of a printed circuit board arranged in the receptacle. In particular, the essential extent of the positioning projections can be rotated by approximately 90 ° with respect to the essential extent of the locking projection. For example, the positioning projections can extend from the respective positioning elements essentially in the width direction towards the printed circuit board and the locking projection can extend essentially in the longitudinal direction towards the printed circuit board, in particular into a locking recess of the printed circuit board.

A positioning gap that is configured between the positioning projections in the width direction can be smaller than a thickness of a circuit board in the width direction, correspond precisely to a thickness of a circuit board in the width direction or be greater than a thickness of a circuit board in the width direction.

Due to the configuration of the positioning gap between the positioning projections in the width direction of the elongated receiving body, the circuit board can advantageously be clamped, supported or limited in its deflection in the width direction.

In exemplary embodiments, the positioning projections can be configured in a section with a cutting plane parallel to the height direction and width direction to taper in the extension towards the printed circuit board or the opposite positioning projection in the height direction. In other words, the positioning projections can, for example, have an inclined upper side and / or an inclined lower side. The upper side of the positioning projection towards the printed circuit board can in particular be configured with a decreasing height. The underside of the positioning projection can be configured in particular with increasing height towards the printed circuit board.

By means of an upper side of a positioning projection that is inclined downwardly towards a printed circuit board to be inserted, the printed circuit board can advantageously be guided or centered for arrangement in the receptacle during an insertion process, thereby facilitating assembly or arrangement of the printed circuit board.

By means of an underside of a positioning projection that is inclined upwardly towards the circuit board, for example, the circuit board can advantageously be guided during a removal process without a Additionally restrict movement of the circuit board in height direction.

In alternative embodiments, the positioning projections can have concave sections which can face the printed circuit board and can be configured to clamp the printed circuit board in the width direction, to guide it with an accurate fit or to limit the deflection of the printed circuit board.

In other words, another aspect of the invention relates to a use of a circuit board holder, according to the above aspect or according to one of the above preferred, exemplary and alternative embodiments, for locking a circuit board in the receptacle of a circuit board holder, i.e. for locking a circuit board on a base circuit board.

In 1 defines three spatial directions, namely the longitudinal direction l , the direction of elevation b and the width direction b which does not have a fixed origin on the circuit board bracket 10 to have. The longitudinal direction l runs essentially parallel to an elongated extension of an elongated receiving body 20th the circuit board bracket 10 . The direction of elevation H runs essentially perpendicular to the longitudinal direction l and is also essentially perpendicular to a base circuit board 150 to which the PCB holder 10 is configured to be pinned.

The second ending 22nd is or comprises a transition area, in particular a transition area in the longitudinal direction l behind, between the elongated receiving body 20th and the second fixing portion 32 , which on the elongated receiving body 20th is arranged. The first ending 21 and the second end 22nd of the elongated receiving body 20th are therefore to be understood in each case as a transition area rather than a fixed geometric location, in particular when the elongated receiving body 20th integral or in one piece with the first fixing section 31 and the second fixing portion 32 is designed, in particular manufactured.

Furthermore, the pairs of positioning elements 50 , as in 1 shown in height direction H compared to the recording 24 sticking out or standing, i.e. reaching up or standing.

The positioning elements 52 of the pairs of positioning elements 50 can in particular essentially have a U-profile along the height direction H compared to the recording 24 protrude or extend. The U-profile of the positioning elements 52 enables a vibration-proof and rigid configuration of the positioning elements 52 , and at the same time a design that is particularly suitable for injection molding, since accumulations of injection molded material are avoided, which in turn can reduce or avoid possible distortion.

Furthermore shows 1 that the circuit board bracket 10 two elastically deformable locking devices 40 which is adjacent to the first end 21 or second end 22nd of the elongated receiving body 20th are arranged. The elastically deformable locking device 40 in each case has an extension essentially in the vertical direction H on and is also in the longitudinal direction l spaced from the pair of positioning members 50 arranged, in particular in the longitudinal direction l , turned away from the recording 24 , spaced from the pair of positioning members 50 arranged.

3a shows a portion of a circuit board holder 10 in oblique view. First clarified 3a the extent of the positioning elements 52 of the pair of positioning elements 50 in height direction H with a U-profile, on the inclusion 24 out.

Furthermore shows 3a that the mold opening 44 of the tool lead-through element 42 is preferably configured round or cylindrical and extends along a tool opening axis 45 extends. Furthermore is the tool opening 44 preferably provided with a tool opening bevel, which automatically centering when inserting or guiding a tool (not shown) through the tool opening 44 enables or introducing a tool into the tool opening 44 simplified. The outer edge of the tool opening bevel preferably has a diameter that is in relation to a diameter of the tool opening 44 in the range from about 1.05 to about 1, 5, particularly preferably in the range from about 1.15 to 1.35, whereby the insertion of a tool into the tool opening 44 can advantageously be facilitated.

The tool opening 44 is always configured as a through hole to ensure that a tool can pass through. The tool opening 44 is preferably configured with a diameter that corresponds to 1.05 to 1.3 times a cross-sectional dimension of a tool. The tool opening 44 can in particular have a cross-sectional diameter of approximately 1.5 mm to approximately 3.5 mm.

The unlocking recess 72 can be configured as a through hole with a constant diameter, or configured as a blind hole with a constant diameter, or in particular configured as a through hole with a diameter that is constant in sections. An unlocking recess 72 , which is configured as a blind hole with a constant diameter, enables that when inserting a tool into the unlocking recess 72 damage to the base circuit board 150 can advantageously be avoided since the inserted tool does not extend to the base circuit board 150 got. In contrast, an unlocking recess allows 72 , which is configured as a through hole with a constant diameter in sections, that via the unlocking recess 72 In addition, a fastening element, such as a screw, for additional fastening of the circuit board holder 10 on a base circuit board 150 can be introduced. The unlocking recess 72 can, for example, have a cross-sectional diameter in the range from approximately 1.5 mm to approximately 3.5 mm, preferably in the range from approximately 1.7 mm to 2.5 mm. The unlocking recess 72 can furthermore have, for example, a smaller cross-sectional diameter than the tool opening 44 . This can ensure that the mold opening 44 allows easy implementation of a tool while the unlocking recess 72 ensures tilting of the tool while the tool is in the unlocking recess 72 , for example along the height direction H or along the axis of the unlocking recess 73 , is introduced.

As also in 3a shown are the mold opening axis 45 and the unlocking recess axis 73 different from each other.

The mold opening axis 45 is preferred in the longitudinal direction l of the elongated receiving body 20th to the unlocking recess axis 73 spaced so that when passing a tool through the tool opening 44 and then inserting a tool into the unlocking recess 72 , the elastically deformable locking device 40 elastic in the longitudinal direction l , away from the recess 24 , is deformed.

In further exemplary embodiments, the tool opening axis 45 and the unlocking recess axis 73 configured parallel to one another, skewed to one another, or intersecting at a certain point. Are the mold opening axis 45 and the unlocking recess axis 73 configured so that they intersect at a certain point, the point is preferably to be selected so that it is below the upper edge of the unlocking recess in the height direction 72 is configured to elastic deformation of the elastically deformable locking device 40 to ensure. This elastic deformation leads to a locking projection 46 from the locking recess 120 the circuit board 100 is moved.

Furthermore shows 3a that the tool insertion element 70 with a plurality of stiffening elements 71 can be provided on the outside, which extends essentially in the height direction H extend. By a plurality of stiffening elements 71 that on the tool insertion element 70 is arranged, is the tool insertion element 70 particularly stiff against deformation in the longitudinal direction l so that when inserting a tool into the tool insertion element 70 it is ensured that essentially the elastically deformable locking device 40 elastically deformed while the tool insertion element 70 remains undeformed or is only slightly deformed.

The stiffening elements 71 can for example in the form of ribs on the outside of the Tool insertion element 70 be arranged or formed.
