Description

The present invention relates to a circuit board holder and a method for producing a circuit board holder.

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

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

Printed circuit board holders for accommodating printed circuit boards in vehicles are subject to shocks and vibrations, in particular when a vehicle is moving. In addition, the individual vehicle development places different, often conflicting requirements on the hardware that is to be installed in a vehicle.

U.S. 4,712,848 A describes an electrical connector for making electrical connections to a printed circuit board. The connector includes a latch for attaching the printed circuit board to the connector. The connector is mounted on another printed circuit board and makes further electrical connections with it. The latch cooperates with slots located on opposite edges of the printed circuit board and includes a strap member that extends along the rear of the connector housing. Releasing the latch is relatively easy, without exerting any detrimental forces on the printed circuit boards, by inserting a flathead screwdriver into the opening formed by the yoke member and the back wall of the connector housing and turning the screwdriver in any direction to release the to release the lock.

US 2009/0 017 666 A1 describes an electrical connector for receiving a daughter card with multiple conductive surfaces. The electrical connector has a socket with an elongated slot for receiving the daughter card. The slot has electrical terminals for engaging the multiple conductive surfaces on the daughter card and electrically connecting the daughter card to the connector. A latch at each end of the elongated slot secures the daughter card to the connector. The latch includes a pair of inwardly opposed securing hooks and a pair of release members.

U.S.A. 4,557,548 describes a connector directed for attachment to a printed circuit board and intended to receive the edge of a chip-carrying ceramic substrate. The connector includes a dielectric housing shaped to receive a series of stamped and formed U-shaped metal contacts in respective cavities separated by U-slotted partitions that limit the insertion depth of the substrate. Each contact tends to separate the flexure required to accommodate the circuit board from the flexure required to accommodate offset due to warping. A U-shaped contact is formed with substrate contact surfaces on convexly rolled inner surfaces of directly opposed upright arms and a flat pin formed down from the base of the contact portion. The stamped metal strips are mounted through a slot in the base of the housing, the slot being tapered towards the cavity to allow lateral flexing of the pin perpendicular to its rolled surface.

It is therefore the object of the present invention to provide a printed circuit board holder which is vibration-resistant and, moreover, meets the requirements of vehicle development.

The object described above is solved by the subject matter of the independent claims, preferred embodiments are the subject matter of the dependent claims.

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

• - an elongate receiving body,
  • -- the elongate receptacle body having a receptacle for locating a contact portion of the circuit board therein;
  • -- wherein the elongate receiving body has a clamping portion in the height direction for locating the contact portion of the printed circuit board therein; and
  • -- wherein the elongate receiving body has a support section in the height direction below, adjoining the clamping section,
    • -- wherein the support section has a thinner wall thickness in the longitudinal direction of the elongate receiving body, at least in sections, than the clamping section; and
    • -- wherein the elongate receiving body has at least one pair of stiffening ribs, the stiffening ribs of the at least one pair of stiffening ribs being arranged on opposite outer sides of the elongate receiving body.

The present circuit board holder for receiving a circuit board and for fixing the circuit board to a base circuit board in a vehicle advantageously allows the circuit board holder to be particularly vibration-resistant due to the at least one pair of stiffening ribs.

In addition, the sectional configuration of the support section, which has a thinner wall thickness in the longitudinal direction of the elongated receiving body at least in sections than the clamping section, makes it possible to avoid large accumulations of injection-molded material during a manufacturing process, such as an injection molding process, as a result of which the injection-molded material solidifies Material a strong shrinkage in the area of accumulations of material is avoided. As a result, distortion of the printed circuit board holder, in particular distortion of the elongate receiving body, can be reduced or avoided.

Thus, based on the present circuit board holder, a circuit board holder that is both vibration-resistant and reliable to manufacture can be provided. In other words, using the present circuit board holder, a circuit board holder that is both vibration-resistant and dimensionally stable can be provided.

In particular, the stiffening ribs of the at least one pair of stiffening ribs can be arranged on opposite outer sides of the elongated receiving body in the width direction.

Furthermore, the support section can in particular have a thinner wall thickness, measured in the width direction, than the clamping section.

For example, the clamping section can be configured to clamp the contact section of a printed circuit board in order to enable the printed circuit board to be arranged in a particularly vibration-proof manner in the receptacle of the printed circuit board holder.

In the further course, various terms are used repeatedly, the understanding of which is to be made easier by the following definitions.

Elongated: In the present case, the term elongate is mostly used with the term receiving body and indicates that the element referred to therein, in particular the receiving body, has an extent in the longitudinal direction which is significantly greater than its extent in the width and/or height direction. With respect to the elongate containment body, it may have a length of about 20 to about 60 times a width of the elongate containment body or a length of about 5 to about 40 times a height of the elongate recording body.

Longitudinal direction: The longitudinal direction describes a direction in which the printed circuit board holder or the elongated receiving body has its longest extent. Furthermore, the longitudinal direction is substantially parallel to a long edge of a contact portion of a printed circuit board that can be placed in the receptacle of the elongate receptacle body, such as in 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 surface area. Furthermore, the height direction can essentially correspond to a direction in which the printed circuit board is pushed or plugged into the receptacle of the elongated receptacle body.

Width direction: The width direction is generally substantially perpendicular to the length direction and the height direction. In the present application, the width direction is essentially used to describe wall thicknesses, wall thicknesses or the like. The width direction may further correspond to an edge of a contact portion of a circuit board that extends along the short side.

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

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

Vibration-resistant: The term vibration-resistant is mostly used here to characterize a connection, connection or fixation. Vibration-resistant describes the fact that a connection, connection or fixation is subject to vibrations and shocks in the spectrum that is typical for the application and in a certain area beyond that does not solve by itself.

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 on its own in the event of vibrations and shocks in the application-typical spectrum and in a certain range beyond that.

Non-destructively detachable: A non-destructively detachable connection is a connection between two elements or components whose detachment causes the partial or complete destruction of at least one of the two elements or components that are detached from one another. The connection of two elements cannot be detached without being destroyed, even if the use of solvents to separate the two elements from one another causes at least the negative impairment of the material properties or structure of at least one of the two elements. Examples of non-destructively detachable connections are adhesive connections, for example using adhesives, material connections, which are produced, for example, by welding processes, mechanical connections, which are produced, for example, by riveting two or more elements, and other connections that do not have the associated property of meet non-destructive detachability.

Base circuit board: Base circuit board means a printed circuit board or PCB (printed circuit board) that serves as the basis for connection or fixation. The base circuit board can be any circuit board. Alternatively, the base circuit board can also describe a base module, which is used, among other things, for connecting or fixing further circuit boards.

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

True to shape: The term true to shape describes the behavior of an element during a manufacturing process, such as an injection molding process, whereby a negative mold or cavity is used to manufacture the element and the element after the manufacturing process is only slightly distorted compared to the negative mold or cavity of the element having. After solidification, an element that has been manufactured or injection-molded with true shape can, in particular, have edges which have a deviation from corresponding edges of the negative mold or cavity of less than 10°, for example in a range between 0° and 10°, further for example in is in a range between 0° and 4°, preferably in a range between 0° and 2°, further preferably in a range between 0° and 1°, and particularly preferably in a range between 0° and 0.5° ..

According to preferred embodiments of the circuit board holder, the stiffening ribs can be arranged on opposite outer sides of the elongated receiving body in a region of the support section.

In other words, in preferred embodiments of the printed circuit board holder, the stiffening ribs can be arranged on opposite outer sides of the elongated receiving body at the level of the support section or adjacent to the support section.

By arranging the stiffening ribs on opposite outer sides of the elongated holding body in an area of the support section that adjoins the clamping section below in the height direction, the stiffening ribs are provided on the elongated holding body in the vicinity of the base circuit board, i.e. below in the height direction, which on the one hand Focus of the circuit board holder is kept low in the height direction, and at the same time a suitable stiffening of the circuit board holder is made. Thus, the printed circuit board holder can advantageously be configured to be vibration-resistant.

Furthermore, the fact that the stiffening ribs are arranged on opposite outer sides of the elongated receiving body in a region of the support section makes it possible for a suitable cross section to be provided during a manufacturing process for a printed circuit board holder, such as an injection molding process, which promotes or facilitates a material flow of the injection molded material. suitably allows.

In exemplary embodiments, the circuit board mount may have more than one pair of stiffening ribs on opposite exterior sides of the elongate receiving body on or in a region of the support section.

In further exemplary embodiments, the circuit board holder may have one or more pairs of stiffening ribs arranged in a region of the support section, and additionally have a pair or more pairs of stiffening ribs arranged in a region of the clamping section.

In alternative embodiments, the printed circuit board holder can have stiffening ribs, which are arranged in sections in the area of the support section and are arranged in sections in the area of the clamping section.

In further alternative embodiments, the printed circuit board holder can only have stiffening ribs in one of the areas of the support section and the clamping section.

In preferred embodiments of the circuit board holder, the stiffening ribs can be trapezoidal in a section with a section plane parallel to a height direction and a width direction.

In other words, in preferred embodiments of the printed circuit board holder, the stiffening ribs can be trapezoidal in a section with a section plane parallel to a height direction of the elongated receiving body and to a width direction of the elongated receiving body. In other words, in preferred embodiments, the stiffening ribs can have a trapezoidal shape in a cross section.

Advantageously, the trapezoidal design of the stiffening ribs in a section with a section plane parallel to a height direction and width direction of the elongated receiving body allows a suitable cross section for the injection molded material to flow through to be provided during the injection molding process, with contour jumps being avoided and uniform solidification being promoted or enabled is, in particular, a uniform solidification of the circuit board holder is promoted or enabled.

The stiffening ribs, which are trapezoidal in a cross section or in a section with a cutting plane parallel to a height direction and a width direction of the elongated receiving body, preferably have a base of the trapezium on the opposite outer sides of the elongated receiving body. Furthermore, the stiffening ribs, which are trapezoidal in a cross section or section, preferably have a shoulder portion which is arranged at a distance from the base substantially in the width direction of the elongated receiving body. In particular, the shoulder section can be formed facing away from the base of the trapezoidal shape in the width direction and have a smaller extent in the height direction of the elongated receiving body than the base of the trapezoidal shape. Furthermore, the base of the trapezoidal shape and the shoulder portion of the trapezoidal shape may be parallel to each other. For example, at least the shoulder section, in the above-described cross section or section, can be essentially parallel to the height direction.

Further, the stiffening ribs, which are formed in a trapezoidal shape in a cross section, have two trapezoidal sides which can extend widthwise inclined between the base and the shoulder portion of the trapezoidal shape. Specifically, the trapezoidal sides may extend inclinedly between the base and the shoulder portion of the trapezoidal shape such that the trapezoidal shape is a tapered shape in the height direction toward the shoulder portion.

In exemplary embodiments, the trapezoidal sides are inclined according to a previously described section or cross section of the stiffening ribs at an angle relative to the width direction of the elongated receiving body in the range from about 20° to about 80°, preferably in a range from about 30° to about 60°. and most preferably inclined at an angle of about 45°.

The angle of inclination of the sides of the trapezium below 45° advantageously makes it possible to reduce material consumption, and thus a particularly cost-effective production.

On the other hand, inclination angles of the trapezium sides above 45° allow an advantageous cross section to be provided for enabling a suitable material flow of injection molded material.

Embodiments of the trapezoid sides with an angle of inclination of approximately 45° combine the advantages of limited material consumption and an advantageous material flow during an exemplary injection molding process.

In alternative embodiments, the stiffening ribs may extend widthwise from the elongate receiving body with a curvature when viewed in a cross-section of the stiffening ribs. The curvature can in particular have a radius. this makes possible an advantageous material flow during an exemplary injection molding process.

In exemplary embodiments of the printed circuit board holder, the cross section of the stiffening ribs is designed as an isosceles trapezoid.

In exemplary embodiments, the cross section or the section with the cutting plane parallel to a height direction and a width direction of the elongated receiving body can deviate from a trapezoidal shape, in particular be omega-shaped, semicircular, part-circular, polygonal or have any other shape. In further exemplary embodiments, the stiffening ribs can have a trapezoidal shape in a cross section or in a section with a cutting plane parallel to a height direction and a width direction of the elongated receiving body, with a shoulder section being separated from inclined trapezoidal sides in the width direction, in particular facing away from one in the width direction Outside of the elongate body is deposited to provide a particularly advantageous cross-section to ensure a flow of material, for example injection molded material.

In preferred embodiments of the circuit board holder, a widthwise outermost shoulder portion of the stiffening ribs may be formed substantially flat, wherein the shoulder portion may have a shoulder portion height in the height direction that is greater than a partially thinner wall thickness of the support portion of the elongated receiving body.

The shoulder section or shoulder section that is outermost in the width direction can in particular be a shoulder section of the respective stiffening rib that is outermost in the width direction of the receiving body. Furthermore, the shoulder section can, for example, be formed parallel to a vertical direction of the receiving body, in particular parallel to a vertical direction and longitudinal direction of the elongated receiving body. The height of the shoulder section can in particular be measured in the height direction of the elongated receiving body.

The fact that an outermost shoulder section is essentially flat, in particular parallel to the height direction of the elongated receiving body, advantageously enables uniform solidification of the injection-molded material in the region of the stiffening rib during an exemplary injection molding process. In this way, in the area of the stiffening rib, cross sections that taper to a point can be avoided, which can cause uneven solidification during injection molding and thus distortion during solidification.

The fact that the shoulder section preferably has a shoulder section height in the height direction of the elongated holding body that is greater than a wall thickness of the support section of the elongated holding body that is thinner in sections, makes it possible for an advantageously large cross section to ensure a suitable material flow during an injection molding process to be provided. This ensures in particular a material flow of injection-molded material along the longitudinal direction of the elongated receiving body for all sections, ie thick-walled and thin-walled sections of the support section.

In exemplary embodiments, the ratio of the heightwise dimension of the shoulder portion height to the widthwise thickness of the thin-walled portion of the support portion may be in the range of about 1.0 to about 2.0, preferably in the range of about 1.2 to about 1.8, and particularly preferably in the range of about 1.4 to about 1.6.

A thin-walled portion of the support portion may be, for example, about 0.2 mm to about 0.8 mm thick in the width direction, preferably about 0.3 mm to about 0.6 mm thick, and a shoulder portion height may be about 0.2 to about 0.2 mm thick in the height direction 1.6 mm high, preferably about 0.4 mm to about 0.8 mm high.

The above-described ratios and dimensional ranges of the shoulder portion height in the height direction to the thickness of the thin-walled portion of the support portion in the width direction advantageously enable distortion to be reduced or avoided in an exemplary injection molding method as the manufacturing method.

Preferably, the above-described ratios and dimensional ranges of the shoulder portion height in the height direction to the thickness of the thin-walled portion of the support portion in the width direction are substantially constant in an extension of the clamp portion along the longitudinal direction. On the one hand, this makes it possible to reduce or avoid distortion in an exemplary injection molding process and, on the other hand, to securely clamp a printed circuit board.

In alternative embodiments, the shoulder portion height may be less than or equal to the portionally thinner wall thickness of the thin be ren section of the elongated receiving body.

In preferred embodiments of the printed circuit board holder, the elongated receiving body can have a first and a second end in the longitudinal direction, the printed circuit board holder having a first fixing section which is arranged at the first end of the elongated holding body and a second fixing section which is arranged at the second end of the elongated receiving body, wherein at least a first fixing element is fixed on the first fixing section in order to be fixed on the base circuit board, and at least a second fixing element is fixed on the second fixing section in order to be fixed on the base circuit board, with the stiffening ribs of the at least one pair of stiffening ribs can extend in the longitudinal direction between a first fixing area of the first fixing element and a second fixing area of the second fixing element.

The stiffening ribs, which extend in the longitudinal direction between a first fixing area of the first fixing element and a second fixing area of the second fixing element, enable an advantageous flow of forces, forces from the base circuit board reaching the fixing elements, via the stiffening ribs to the fixing element lying opposite in the longitudinal direction and from there get back into the base circuit board. A flow of forces is thus made possible, which directs forces from a fixing section of the printed circuit board holder via the stiffening ribs to a fixing section lying opposite in the longitudinal direction. Since the stiffening ribs are arranged on opposite outer sides of the elongated receiving body, a flow of forces through the printed circuit board due to vibrations, shocks and other forces can advantageously be limited or even completely prevented, which advantageously protects the printed circuit board.

In exemplary embodiments, exactly two first fixing elements can be fixed on the first fixing section and exactly two second fixing elements can be fixed on the second fixing section, with the two first fixing elements and the two second fixing elements each being arranged opposite one another in the width direction. As a result, the stiffening ribs, which are arranged on opposite outer sides of the elongated receiving body, can extend between the fixing areas of the respective one first and one second fixing element. This enables a force distribution that is separate in the width direction, with the conduction of forces through the printed circuit board being advantageously restricted or even avoided.

In alternative embodiments, a multiplicity of fixing elements can be arranged on the first fixing section and a different multiplicity of fixing elements can be arranged on the second fixing section.

In further alternative embodiments, the circuit board holder can have a multiplicity of pairs of stiffening ribs, wherein no pair, only one pair, or several pairs can extend between fixing areas on the first fixing section and the second fixing section.

In preferred embodiments of the printed circuit board holder, each stiffening rib can have an extent in the width direction which, in relation to the wall thickness of the support section, which is thinner in sections in the width direction, is in the range from about 0.5 to about 1.6, preferably in the range from about 0.6 to about 1. 2, particularly preferably about 0.8.

The fact that each stiffening rib has an extent in the width direction that is in the range of about 0.5 to about 1.6 in relation to the partially thinner wall thickness of the support section, on the one hand a particularly advantageous stiffening is provided, which makes the circuit board holder particularly vibration-resistant. On the other hand, the above-described ratio of the extension in the width direction of the stiffening rib to the partially thinner wall thickness of the support section can provide a suitable cross section for ensuring the material flow of injection molded material during an exemplary injection molding process. Furthermore, the conditions described above make it possible to reduce or avoid distortion in an injection molding process as an exemplary production process.

The effect described above with regard to the ratio of the extent of the stiffening rib in the width direction to the wall thickness of the support section, which is thinner in sections, is increased in the range from approximately 0.6 to approximately 1.2, in particular in the range around approximately 0.8. Thus, on the one hand, a particularly stable, in particular vibration-resistant, circuit board holder can be provided, and at the same time a suitable cross section for promoting the material flow of injection-molded material in an exemplary injection molding process can be provided.

In alternative embodiments, the stiffening rib may have a latitudinal extent have tion, which deviates from a ratio to a widthwise sectionally thinner wall thickness of the support section of about 0.5 to about 1.6.

In preferred embodiments of the circuit board holder, the stiffening ribs can be trapezoidal in a cross section or in a section with a cutting plane parallel to a width direction and a height direction, wherein the stiffening ribs are preferably isosceles trapezoidal and have a base angle in the range from about 25 ° to about 80 °, preferably in the range from about 40° to about 60°, and more preferably from about 45°.

The base angle can in particular be measured against the width direction of the elongated receiving body.

The angle of inclination of the sides of the trapezium of less than 45° advantageously makes it possible to reduce material consumption and, consequently, to produce it in a particularly economical manner.

On the other hand, inclination angles of the trapezium sides above 45° allow an advantageous cross section to be provided for ensuring a suitable material flow of injection molded material.

Embodiments of the trapezoid sides with an angle of inclination of approximately 45° combine the advantages of limited material consumption and an advantageous material flow during an exemplary injection molding process.

In preferred embodiments of the circuit board holder, the elongated receiving body can have a wall structure, the wall structure in the area of the clamping section having alternating thin-walled sections and thick-walled sections in the longitudinal direction, the thick-walled sections being configured to extend up to the contact area of the circuit board arranged in the receptacle extend, and the thin-walled portions are configured not to extend up to the contact area of the printed circuit board arranged in the receptacle.

The longitudinal direction along which the wall structure of the elongate receiving body has alternating thin-walled sections and thick-walled sections can in particular be a longitudinal direction of the elongate receiving body.

By providing a wall structure in the area of the clamping section, which alternately has thin-walled and thick-walled sections in the longitudinal direction, with the thin-walled sections not extending to a contact area of the printed circuit board, it is possible for contact elements to be arranged in the longitudinal direction between two thick-walled sections.

In addition, a wall structure that has alternating thin-walled sections and thick-walled sections allows the wall structure to provide a particularly large surface area, which allows cooling air or cooling air to pass through, so that the wall structure enables increased convective heat transfer and thus an integral cooling or advantageously heat-dissipating function.

In exemplary embodiments, the thick-walled portions may be configured not to extend to the contact area of the circuit board located in the receptacle, and rather be at a predefined distance from the contact area of the circuit board located in the receptacle, which may be, for example, in the range of about 0.03 mm to about 1 mm, preferably in the range from about 0.05 mm to about 0.4 mm, and more preferably in the range from about 0.1 to about 0.2 mm.

In preferred embodiments of the printed circuit board holder, a ratio of the extension in the width direction of the thin-walled sections to the extension in the width direction of the thick-walled sections can be in the range from about 0.2 to about 0.9, preferably in the range from about 0.4 to about 0.8. more preferably about 0.7.

In other words, in preferred embodiments of the circuit board holder, a ratio of the wall thickness of the thin-walled sections, measured in the width direction, to the wall thickness of the thick-walled sections, measured in the width direction, can be in the range from about 0.2 to about 0.9, preferably in the range from about 0 .4 to about 0.8, more preferably about 0.7.

The thin-walled sections can in particular be the thin-walled sections of the wall structure in the contact area of the elongated receiving body. The thick-walled sections can in particular be the thick-walled sections of the wall structure in the contact area of the elongated receiving body.

The above-described preferred ratios of the extent in the width direction of the thin-walled sections to those of the thick-walled sections make it possible on the one hand to provide a particularly large surface area so that the wall structure has an advantageous heat dissipation has a leading function. On the other hand, a suitable cross section, in particular a sufficient cross section, is provided for a material flow of injection molded material during an exemplary injection molding process, and uniform solidification of the injection molded material is made possible, so that distortion in an injection molding process as an exemplary manufacturing process can be reduced or avoided.

In alternative embodiments, the ratios of the extent of the thin-walled sections to the extent of the thick-walled sections can deviate from the ranges mentioned above.

In exemplary embodiments, the thin-walled section of the wall structure in the contact area of the elongate receiving body can be configured with a thickness or wall thickness that varies along the height direction. The thin-walled section of the wall structure can first have a region with a constant thickness or wall thickness, following the height direction downwards and beginning with an upper edge of the receptacle of the elongated receiving body in the height direction, then have a region with a continuously decreasing thickness or wall thickness, and finally open into the thickness or wall thickness of a thin-walled section of the elongated receiving body in the region of the support section. A region of the thin-walled section of the wall structure with a constant wall thickness, which adjoins in the height direction below an upper edge of the receptacle, advantageously makes it possible to support a contact element in the width direction. An area of the thin-walled section of the wall structure with a continuously decreasing wall thickness, which is arranged below the area with a constant wall thickness and above the thin-walled section in the support area, advantageously makes it possible to provide a suitable cross section to ensure a material flow for, for example, injection molded material.

In further alternative embodiments, the thin-walled section can in particular have projections or recesses in order, for example, to advantageously enable additional support and stabilization of a contact element during the insertion of a printed circuit board.

The receptacle can in particular be a hollow space or a cavity which is configured to accommodate a lower section of a printed circuit board, in particular a contact section of a printed circuit board. In particular, the receptacle can be configured essentially U-shaped or V-shaped in a section with a section plane in the height direction and in the width direction. The receptacle can, for example, extend at the same height as the clamping area of the elongate receptacle body. Alternatively, the receptacle can extend in the height direction beyond the height of the clamping area. The receptacle can also have an insertion chamfer, for example, at the upper ends of the sides, which extend essentially parallel to the sides of a printed circuit board, in order to make it easier to insert a printed circuit board into the receptacle. Alternatively, the receptacle can have a rounding or other contour at the upper ends of the sides, which extend essentially parallel to the sides of a printed circuit board.

Furthermore, the receptacle can, for example, have a receptacle base which configures a surface or a section up to which the circuit board can be inserted into the receptacle or into the elongated receptacle body. In particular, the receiving base can extend essentially parallel to the width direction and to the longitudinal direction of the elongated receiving body. The receiving base can also be located in particular at a height along the height direction, which approximately separates the clamping section from the support section in the height direction. In exemplary embodiments, the receptacle floor may be at a height along the height direction that precisely separates the clamping portion from the support portion of the elongate receptacle body in the height direction.

A further aspect of the invention relates to an injection molding method for producing a circuit board holder according to the preceding aspect or one of the preceding preferred, exemplary or alternative embodiments as mentioned above.

In other words, a further aspect of the invention relates to an injection molding process for producing a circuit board holder, in particular an elongated receiving body, while fixing elements for fixing the circuit board holder to a base circuit board can be produced or provided independently of the injection molding process, and only when the circuit board holder is mounted on the base circuit board and can be fixed to fixing portions of the circuit board holder.

In exemplary embodiments, the circuit board holder can be produced in a multi-component injection molding process, with fixing elements being provided, in particular metallic fixing elements being provided, and an elongated receiving body as well integrally connected fixing sections are connected to the provided fixing elements by the injection molding process.

The preferred, exemplary and alternative embodiments of the circuit board holder described above and their effects relate equally to the injection molding process for producing a circuit board holder.

1 shows a circuit board holder 10. Here are in 1 three spatial directions defined, namely the longitudinal direction I, the height direction b and the width direction b, which have no fixed origin on the circuit board holder 10. The longitudinal direction I runs essentially parallel to an elongated extension of an elongated receiving body 20 of the circuit board holder 10. The height direction h runs essentially perpendicular to the longitudinal direction I and is also essentially perpendicular to a base circuit board 150 on which the circuit board holder 10 is configured fixed to become. The width direction b runs essentially perpendicular to the longitudinal direction I and to the vertical direction b, so that in particular a right-handed directional system consists of the longitudinal direction I, vertical direction h and width direction b.

As in 1 As shown, the elongate receiving body 20 has a receptacle 24 which opens upward in the height direction and is configured to place a contact portion 110 of a printed circuit board 100 therein. Furthermore, the elongate receiving body 20 can optionally have a coding 23 which is arranged in the receptacle 24 of the elongate receiving body. The coding 23 can be configured to engage in a coding recess 130 of a circuit board 100 when the circuit board 100 is arranged in the recess 24 . The circuit board holder 10 can be designed or restricted to accommodate a specific type of circuit board 100 based on the coding 23 of the elongated receiving body 20 .

In alternative embodiments of the printed circuit board holder 10, the elongate receiving body 20 has no coding 23.

As in 1 shown, the elongate receiving body 20 has a first end 21 and a second end 22 in the longitudinal direction I, the first end 21 and the second end 22 in the longitudinal direction I being essentially opposite one another. The first end 21 is or includes a transition area, in particular a transition area in the longitudinal direction I at the front, between the elongated receiving body 20 and the first fixing section 31 which is arranged on the elongated receiving body 20 . The second end 22 is or includes a transition region, in particular a transition region in the longitudinal direction I at the rear, between the elongated receiving body 20 and the second fixing section 32 which is arranged on the elongated receiving body 20 . The first end 21 and the second end 22 of the elongate receiving body 20 are therefore to be understood as a transition region rather than as a fixed geometric location, in particular if the elongate receiving body 20 is formed integrally or in one piece with the first fixing section 31 and the second fixing section 32 , In particular is made.

In exemplary embodiments, the elongate receiving body 20 can be manufactured integrally or in one piece with the first fixing section 31 and the second fixing section 32 in an injection molding process, as a result of which the elongate receiving body 20, the first fixing section 31 and the second fixing section 32 have or are made of the same material consist, in particular, have or consist of a plastic such as PA, PP, PE, EP resins, PMMA, PEEK or PUR, or optionally, in particular, a fiber-reinforced plastic such as PA, PP, PE, EP resins, PMMA, PEEK, PUR with a glass fiber content in the range of 5% to 40% or consist of such as PA6GF30, PA66GF30, PA6GF15 or PA66GF15. In particular, the production of the circuit board holder 10 or the elongated receiving body 20, the first fixing section 31 and the second fixing section 32 from fiber-reinforced plastic makes it possible to increase the vibration resistance or stability of the circuit board holder 10 in a targeted manner and to increase the thermal conductivity in a targeted manner in order to To improve heat transport or -Abtransport between circuit board 100 and base circuit board 150.

In further exemplary embodiments, the elongated receiving body 20 can be manufactured integrally or in one piece with the first fixing section 31 and the second fixing section 32 in a multi-component injection molding process, whereby the elongated receiving body 20, the first fixing section 31 and the second fixing section 32 have different plastics or fiber-reinforced plastics can or can consist of them, whereby targeted material properties for the circuit board holder 10 can be provided.

In alternative embodiments, the elongated receiving body 20, the first fixing section 31 and the second fixing section 32 can be manufactured separately from one another, i.e. in several pieces, and then connected to one another, such as by gluing, welding, screwing or any other method.

The elongate receiving body 20, the first fixing section 31 and the second fixing section 32 can have a length in the longitudinal direction together, for example, in the range from about 80 mm to about 240 mm, preferably a length in the range from about 120 mm to about 180 mm, and particularly preferably have a length of about 165 mm. The elongated receiving body 20, the first fixing section 31 and the second fixing section 32 can each have a width in the range from about 2.8 mm to about 8 mm, preferably a width in the range from about 3.4 mm to about 6 mm, and particularly preferably have a width of about 4.5 mm. In alternative embodiments, the printed circuit board holder 10, in particular the elongate receiving body 20 and the first and second fixing sections 31, 32 adjoining it in the longitudinal direction, can have dimensions which are tailored in particular to the printed circuit board 100 to be arranged in the printed circuit board holder 10 and depend on the above-mentioned values or value ranges differ.

Furthermore shows 1 two pairs of positioning elements 50, the pairs of positioning elements 50 being arranged opposite one another in the longitudinal direction I, in each case on the elongate receiving body 20. For example, the pairs of positioning elements 50 can adjoin the receptacle 24 of the elongated receptacle body 20 in the longitudinal direction I at the front and rear. Furthermore, the pairs of positioning elements 50, as in 1 shown, in the height direction h in relation to the receptacle 24 protrude or stand, ie stretch up or stand.

The positioning elements 52 of the pairs of positioning elements 50 can in particular protrude or extend essentially with a U-profile along the vertical direction h in relation to the receptacle 24 . The U-profile of the posi tionierelemente 52 allows a vibration-resistant and rigid design of the positioning elements 52, and at the same time a particularly injection molding design, since accumulations of injection-molded material are avoided, which in turn can reduce or avoid a possible delay.

Furthermore shows 1 that the circuit board holder 10 has two elastically deformable locking devices 40, which are arranged adjacent to the first end 21 and second end 22 of the elongated receiving body 20. The elastically deformable locking device 40 extends essentially in the height direction h and is also arranged in the longitudinal direction I at a distance from the pair of positioning elements 50, in particular in the longitudinal direction I, facing away from the receptacle 24, at a distance from the pair of positioning elements 50 arranged. In particular, the elastically deformable locking device 40 is spaced apart from the pair of positioning elements 50 by a gap in the longitudinal direction I in order to ensure elastic deformability of the elastically deformable locking device 40 . Furthermore, the wall thickness of the elastically deformable locking device 40, which runs essentially in the height direction h, decreases with increasing height in the longitudinal direction I in order to increase the elastic deformability of the elastically deformable locking device 40 in the longitudinal direction I as the height of the elastically deformable locking device 40 increases. In other words, a wall thickness of the elastically deformable locking device 40 that decreases with increasing height advantageously enables the rigidity of the elastically deformable locking device 40 to be reduced in a targeted manner in order to provide a targeted elastic deformability of the elastically deformable locking device 40 .

As in 1 shown, the elastically deformable locking device 40 has a tool passage element 42 which is provided with a tool passage opening 44 . The tool passage element 42 can in particular be arranged at an upper end of the elastically deformable locking device 40 in the vertical direction h. Furthermore, the tool passage element 42 can be arranged on the elastically deformable locking device 40 , in particular in the longitudinal direction I, facing away from the receptacle 24 .

As in 1 Also shown, the circuit board holder 10 has two tool insertion elements 70 which are each provided with an unlocking recess 72 . As in 1 As illustrated, the tool insertion element 70 has a spacing in the height direction h and a spacing in the longitudinal direction I from the tool passage element 42 . In particular, tool insertion element 70 or unlocking recess 72 of tool insertion element 70 is spaced apart from tool feedthrough element 42 or tool opening 44 in longitudinal direction I, away from receptacle 24, and is arranged below tool feedthrough element 42 or tool opening 44 in height direction h.

As in 1 indicated and further through 3a clarified, the elastically deformable locking device 40 is configured to deform elastically when a tool is guided through the tool opening 44 and into the unlocking recess 72 in such a way, in particular to deform with a bend essentially in the longitudinal direction I, that the printed circuit board 100 is unlocked. by a locking projection 46, which is arranged on the elastically deformable locking device 40, is moved out of a locking recess 120 of the printed circuit board 100.

As in 1 shown further, two first fixing elements 61, 61′ are fixed or arranged on the first fixing section 31, which extend with a region essentially in the width direction b, in particular perpendicular to an outside in the width direction b of the first fixing section 31. The fixing elements 61, 61', 62, 62', as partially shown in 1 1 are configured to be fixed to the base circuit board 150. FIG. By fixing the fixing members 61, 61', 62, 62' to the first and second fixing portions 31, 32, respectively, and configuring them to be fixed to the base circuit board 150, the circuit board holder 10 can be fixed to the base circuit board 150 in a vibration-resistant and stable manner or be attached.

2 shows a circuit board holder 10 in an oblique view and a circuit board 100 not accommodated by the circuit board holder 10 in a front view.

The printed circuit board 100 has a contact section 110 in the lower region in the height direction h, which is configured to be received by the receptacle 24 or to be arranged therein. In addition, the circuit board 100 can have a coding cutout 130 as an interruption of the contact section 110 . Depending on the printed circuit board 100 , the coding recess 130 can be arranged in a different length region of the contact section 120 . In particular, the coding recess 130 is configured with a coding 23 of the elongated receptacle Body 20, when arranging the contact portion 110 in the receptacle 24, to engage, whereby mounting unsuitable or unwanted circuit boards 100 in the circuit board holder 100 can be avoided.

In preferred embodiments, circuit board 100 is part of a DDR5 main memory module. However, in further exemplary embodiments, the circuit board can also be any other main memory module, or any other circuit board.

3a shows a portion of a printed circuit board holder 10 in an oblique view. First clarified 3a the extension of the positioning elements 52 of the pair of positioning elements 50 in the height direction h with a U-profile beyond the receptacle 24.

Furthermore shows 3a that the tool opening 44 of the tool passage element 42 is preferably configured round or cylindrical and extends along a tool opening axis 45. Furthermore, the tool opening 44 is preferably provided with a tool opening chamfer, which enables automatic centering when inserting or guiding a tool (not shown) through the tool opening 44 or simplifies inserting a tool into the tool opening 44 . The outer edge of the tool opening chamfer preferably has a diameter which is in the range from about 1.05 to about 1.5, more preferably in the range from about 1.15 to 1.35, in relation to a diameter of the tool opening 44, whereby the Introducing a tool into the tool opening 44 can advantageously be facilitated.

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

In alternative embodiments, the tool opening 44 may be configured other than a cylindrical shape, particularly configured with a polygonal shape extending along the tool opening axis 45, such as a triangular, square, pentagonal, or hexagonal shape.

Furthermore shows 3a that the unlocking recess 72 of the tool insertion element 70 is preferably configured round or cylindrical and extends along an unlocking recess axis 73 . 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 sectionally constant diameter. An unlocking recess 72, which is configured as a blind hole with a constant diameter, allows damage to the base circuit board 150 to be advantageously avoided when inserting a tool into the unlocking recess 72, since the inserted tool does not reach the base circuit board 150. In contrast, an unlocking recess 72, which is configured as a through hole with a constant diameter in sections, allows a fastening element, such as a screw, for example, to additionally be inserted via the unlocking recess 72 for additional fastening of the circuit board holder 10 to a base circuit board 150. 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 also, for example, have a smaller cross-sectional diameter than the tool opening 44. This can ensure that the tool opening 44 allows a tool to be easily passed through, while the unlocking recess 72 ensures that the tool tilts while the tool is inserted into the unlocking recess 72, for example along the height direction h or along the axis 73 of the unlocking recess.

As also in 3a As shown, the tool opening axis 45 and the unlocking recess axis 73 are different from each other. As a result, when a tool is passed through the tool opening 44 and the tool is then inserted into the unlocking recess 72, the elastically deformable locking device 40 can move the tool insertion element 42, which is arranged on the elastically deformable locking device 40, with the tool opening axis 45 towards the unlocking recess axis 73 or move. The tool opening axis 45 is preferably spaced apart from the unlocking recess axis 73 in the longitudinal direction I of the elongated receiving body 20, so that when a tool is passed through the tool opening 44 and then inserted into the unlocking recess 72, the elastically deformable locking device 40 is elastically deformable in the longitudinal direction I, away from the Recess 24 is deformed.

In further exemplary embodiments, the tool opening axis 45 and the unlocking recess axis 73 may be configured parallel to one another, skewed to one another, or intersecting at a certain point. If the tool opening axis 45 and the unlocking recess axis 73 are configured to intersect at a certain point, the point should preferably be selected such that it is configured in the height direction below the upper edge of the unlocking recess 72 in order to avoid elastic deformation of the elastically deformable Locking device 40 ensure. This elastic deformation leads to a locking projection 46 being moved out of the locking recess 120 of the printed circuit board 100 .

Furthermore shows 3a that the tool insertion element 70 can be provided with a plurality of stiffening elements 71 on its outside, which essentially extend in the height direction h. A plurality of stiffening elements 71, which are arranged on tool insertion element 70, make tool insertion element 70 particularly stiff with respect to deformation in longitudinal direction I, so that when a tool is inserted into tool insertion element 70, it is ensured that essentially elastically deformable locking device 40 is elastic deformed, while the tool insertion element 70 remains undeformed or is only slightly deformed.

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

Furthermore shows 3a as an example for the fixing elements 61, 61′, 62, 62′ a configuration in certain areas, in particular based on the first fixing element 61, which has a fastening area 63, a fixing area 65 and a contour area 67. To differentiate between the areas of the first fixing element 61, 61' and those of the second fixing element 62, 62', the terms first fixing area 63, 63' for the first fixing element 61, 61' are also used for the fixing area 63, 63', 64, 64. and second attachment area 64, 64' for the second fixing element 62, 62', for the attachment area 65, 65', 66, 66' the terms first attachment area 65, 65' for the first attachment element 61, 61' and second attachment area 64 are also used , 64' for the second fixing element 62, 62', as well as for the contour area 67, 67', 68, 68' also the terms first contour area 67, 67' for the first fixing element 61, 61' and second contour area 68, 68' used for the second fixing element 62, 62'.

The first fastening area 63 of the first fixing element 61 extends essentially in the width direction b and protrudes from the first fixing section 31 or the elongated receiving body 20 in the width direction b. Furthermore, the fastening area 63 of the first fixing element 61 preferably extends along an underside of the circuit board holder 10 in order to be fixed to a base circuit board 150 when the circuit board holder 10 is fixed.

In alternative embodiments, the first attachment area 63 of the first fixing element 61 can extend deviating from a width direction and along a bottom side of the circuit board holder 10 as long as the first attachment area 63 is further configured to be fixed to a base circuit board 150 .

The first fixing portion 65 of the first fixing member 61 is configured to fit in a first fixing recess 35 as shown in FIGS 3b , 5a and 5b shown to be fixed. The first fixing area 65 of the first fixing element 61 extends essentially in the height direction h with a contoured shape in the longitudinal direction I. The first fixing area 65 of the first fixing element 61 connects in particular to the first fixing area 63 of the first fixing element 61 and extends with others Words essentially perpendicular to the first fastening area 63 of the first fixing element 61.

The first contour area 67 of the first fixing element 61 preferably has a contour which in sections along a first connection opening 37, as in FIGS 3b , 5a and 5b shown, runs. The first contour area 67 of the first fixing element 61 can in particular extend along and adjacent to an upper side of the first fixing section 31 . Optionally, the first contour area 67 of the first fixing element 61 can extend in particular along and in contact with the upper side of the first fixing section 31 . Due to the fact that the first contour area 67 extends in sections along the contour of the first connection opening 37, the first contour area 67 can be brought into contact with a connection element. The first contour area 67 connects in particular to the first fixing area 65 of the first fixing element 61 and, in other words, extends essentially perpendicularly to the first fixing area 65 of the first fixing element 61.

In exemplary embodiments, a cooling element 14, as in 10 shown attached to the first connection opening 37 of the first fixing portion 31 and the printed circuit board holder 10 are bound, wherein the first contour area 67 can be in contact with the connection element 17, such as a screw. This enables direct heat transfer, in particular conductive heat transfer, from base circuit board 150 via fixing elements 61, 61', 62, 62', via a plurality of connection elements 17 into one or more cooling elements 14, in order to advantageously transfer heat from a base circuit board 150 via a Dissipate cooling element 14. Depending on the temperature gradient, heat can of course also be conducted in the reverse order, ie towards the base circuit board 150 .

3b shows a portion of a circuit board holder 10 according to FIG 3a , wherein the fixing elements 61, 61 'are not shown.

Thus is in 3b In particular, a first fixing recess 35, 35' is shown, which is configured to fix a first fixing area 65, 65' of the first fixing element 61, 61' thereto or to arrange it therein.

Furthermore shows 3b a first connection opening 37, by means of which, in exemplary embodiments, a cooling element 14 can be arranged or attached to the printed circuit board holder 10, as shown in FIG 10 shown. In addition, the first connection opening 37 can provide a further fastening option for fixing the printed circuit board holder 10 to a base printed circuit board 150 . In preferred embodiments, a cooling element 14 can be arranged or attached to the circuit board holder 10 by means of the first connection opening 37, and the connection element 17 connected to the connection opening 37 can also contact the base circuit board 150 or come into contact with the base circuit board 150, resulting in a particularly advantageous conductive Heat transfer from the base circuit board 150 via the connection element 17 and via the fixing elements 61, 61 ', 62, 62' towards the connection element 17, and then further to the cooling element 14 are provided. Depending on the temperature gradient, heat can also be conducted in the reverse order, ie towards the base circuit board 150 .

4a shows fixing elements 61, 61′, 62, 62′ of a printed circuit board holder 10, as can be fixed to a printed circuit board holder 10, but without showing the printed circuit board holder 10 as well. 4a shows in particular the sectional configuration of the fixing elements 61, 61', 62, 62'.

Each fixing element 61, 61', 62, 62' has a fastening area 63, 63', 64, 64', a fixing area 65, 65', 66, 66' and a contour area 67, 67', 68, 68' .

Furthermore, in 4a a connection opening axis 91, 92 is shown. In preferred embodiments, the fixing elements 61, 62 are arranged or fixed rotationally symmetrically relative to the fixing elements 61', 62' with respect to the connection opening axis 91, 92. Rotational symmetry with respect to the connection opening axis 91, 92 means that the fixing elements 61, 62 correspond to the fixing elements 61', 62' by rotating about the connection opening axis 91, 92, in particular can correspond to the fixing positions of the fixing elements 61', 62'. Rotational symmetry of the fixing elements 61, 61', 62, 62' with respect to the connection opening axis 91, 92 can be described by means of point symmetry of the fixing elements 61, 61', 62, 62' in an infinite number of sectional planes that run normal to the connection opening axis 91, 92 will.

In preferred embodiments and as in 4a shown, all fixing elements 61, 61', 62, 62' can be identical, in particular geometrically identical or geometrically identical in shape, to one another. In particular, all fixing elements 61, 61′, 62, 62′ can have or consist of the same material, have the same wall thickness, have the same bending radii, and/or have the same geometric shape. Because the fixing elements 61, 61', 62, 62' are identical to one another, the fixing elements 61, 61', 62, 62' can be produced particularly inexpensively and can also be mounted without the risk of confusion or for fixing to a base circuit board 150 can be used. For example, the fixing elements 61, 61', 62, 62' can each have a wall thickness in the range from about 0.15 mm to about 1 mm, preferably in the range from about 0.2 mm to about 0.6 mm.

As in 4a shown, the fastening areas 63, 63′, 64, 64′ of the fixing elements 61, 61′, 62, 62′ can have two soldering openings 97, 97′, 98, 98′ which are configured at least partially before, in particular during a soldering process to be filled with solder, as a result of which the fixing elements 61, 61′, 62, 62′ can be fixed to a base circuit board 150 in a particularly vibration-resistant and secure manner. In addition, the provision of solder openings 97, 97', 98, 98' prevents solder from flowing uncontrolled over the base printed circuit board 150 during a soldering process, so that very clean and simple soldering is made possible.

In alternative embodiments, the fastening areas 63, 63', 64, 64' of the fixing elements 61, 61', 62, 62' can have more or fewer than two soldering openings 97, 97', 98, 98'.

In further alternative embodiments, the fastening areas 63, 63', 64, 64' of the fixing elements 61, 61', 62, 62' can be configured to liquify in a soldering process and to be directly fixed to a base circuit board 150 itself.

The fixing elements 61, 61', 62, 62' can be produced, for example, in particular by stamping from a metal or metallic material with subsequent bending. The metal or the metallic material that the fixing elements 61, 61′, 62, 62′ have can in particular be a solderable or solderable metal or at least a metal component.

4b shows a plan view of a portion of a printed circuit board holder 10. In particular, in FIG 4b two first fixing elements 61, 61′ are shown, which are opposite each other in a rotationally symmetrical manner with respect to the first connection opening axis 91, in particular are opposite one another in a rotationally symmetrical manner with respect to the first connection opening axis 91. In particularly preferred embodiments and as in 4b shown by means of a distance arrow in the longitudinal direction I between an outer side of the first fixing element 61' and an opposite outer side of the other first fixing element 61, the fixing elements 61, 61' are preferably arranged at a distance from one another in the longitudinal direction I and on opposite sides of the first fixing section 31 in the width direction b arranged.

In other words, the two first fixing elements 61, 61', in particular the fixing regions 65, 65' of the fixing elements 61, 61', are arranged on opposite sides of the first fixing section 31 in the width direction b, and are spaced apart from one another in the longitudinal direction I, see above that mutually facing sides, in particular mutually facing sides of the attachment areas 63, 63 'of the fixing elements 61, 61', have a minimum distance in the longitudinal direction. The minimum distance in the longitudinal direction I can be in the range of about 0.2 mm to 2 mm.

The spacing of the fixing elements 61, 61' in the longitudinal direction I makes it possible for a large number of circuit board holders 10 to be arranged side by side in the width direction b in a space-saving manner, as in FIG 4c shown, so that a first fixing element 61 of a circuit board holder 10 is arranged in the longitudinal direction with the minimum distance from the first fixing element 61 ′ of the other circuit board holder 10 . In other words, a large number of circuit board holders 10 can be arranged next to one another in width direction b in such a way that a fastening area 63 of a fixing element 61 of a first circuit board holder 10 is essentially aligned in longitudinal direction I with a fastening area 63' of a fixing element 61', as shown in FIG 4b and 11b shown.

Furthermore shows 4b clearly that the tool opening 44 of the tool feed-through element 42 is arranged at a distance from the unlocking recess 72 of the tool feed-through element 70 in the longitudinal direction I.

Furthermore shows 4b that the locking projection 46 is arranged on the elastically deformable locking device 40 and extends in the longitudinal direction I towards the receptacle 24.

Furthermore shows 4b the two positioning elements 52 of a pair of positioning elements 50, each having a positioning projection 54. The two positioning elements 52 are arranged on the elongate receiving body 20, in a front end region of the receptacle 24 in the longitudinal direction, and have a U-shape in their extension in the height direction h. In addition, each positioning element has a positioning projection 54 which extends towards the opposite positioning projection 54, the two positioning projections 54, 54 having a positioning gap in the width direction b as a distance from one another. The positioning gap can correspond to a thickness of a printed circuit board 100, be smaller than a thickness of a printed circuit board 100 or greater than a thickness of a printed circuit board 100. A positioning gap that is less than or equal to the thickness of a printed circuit board 100 advantageously allows a printed circuit board 100 can be accommodated or arranged in the printed circuit board holder 10 in a particularly vibration-resistant manner by restricting or blocking a deflection of the printed circuit board in the width direction.

Furthermore indicates 4b indicates that the elongate receiving body 20 has thin-walled sections 27 and thick-walled sections 28 alternating in the longitudinal direction I. The wall thicknesses of the thin-walled sections 27 and the thick-walled sections 28 are, as exemplified in FIG 4b shown, not recognizable by the plan view, but the thin-walled sections 27 next to the longitudinally adjacent thick-walled sections 28 spaces for the arrangement of contact elements 18, as well as by 9b clarified. Opposite thick-walled sections 28 of the elongated receiving body 20 can have a clamping gap in the width direction b. The clamping gap can correspond to the thickness of a printed circuit board 100, be smaller than the thickness of a printed circuit board 100 or be greater than the thickness of a printed circuit board 100. A clamping gap that is smaller than or equal to the thickness of a printed circuit board 100 advantageously enables that a printed circuit board 100 can be accommodated or arranged in the printed circuit board holder 10 in a particularly vibration-resistant manner by restricting or blocking a deflection of the printed circuit board in the width direction. The clamping gap can, for example, have a width in the width direction of approximately 0.6 mm to approximately 5 mm, preferably have a width of approximately 0.9 mm to approximately 3 mm, and particularly preferably have a width of approximately 1.5 mm. The alternating arrangement of thin-walled sections 27 and thick-walled sections 28 also makes it possible to provide a large area in order to enable advantageous heat dissipation from the printed circuit board 100 .

5a shows a sectional view of a portion of a printed circuit board holder 10 with a sectional plane parallel to the vertical direction h and to the longitudinal direction I, so that a first fixing recess 35 can be seen.

The first fixing recess 35 can, in exemplary embodiments and as shown in FIG 5a shown T-shaped. In other words, the first fixing recess 35 in the first fixing section 31 can be configured in such a way that it is formed in sections in a section with a section plane parallel to the height direction h and the longitudinal direction I, with the first fixing recess 35 having a greater extension in the longitudinal direction in the height direction h at the top I has than in the height direction h below. A first fixing element 61, in particular a first fixing region 65 of the first fixing element 61, can be fitted from above in the height direction h downwards in the first fixing recess through the T-shaped first fixing recess 35, with respect to a section with the cutting plane in the height direction h and in the longitudinal direction I 35 are arranged, in particular clamp or latch there, or be glued there.

In exemplary embodiments, the fixing area 65, 65 ', 66, 66' of the fixing elements 61, 61 ', 62, 62' by a press fit and / or by locking, in particular locking behind, and / or by gluing, in particular using a special thermally conductive adhesive, are fixed in the fixing recess 35, 36 and on the fixing section 31, 32, respectively.

Fixing the fixing area 65, 65', 66, 66' of the fixing elements 61, 61', 62, 62' by means of a press fit and/or by latching, in particular by latching behind the fixing recess 35, 36 or on the fixing section 31, 32 can advantageously be simplified if the fixing element 61, 61′, 62, 62′ has or consists of a metallic material and the fixing section 31, 32 has or consists of a polymer material, in other words plastic. This is achieved in that the plastic is deformed or crushed by the metallic material when fixing the fixing area 65, 65', 66, 66' of the fixing elements 61, 61', 62, 62'. This allows the fixing elements 61, 61′, 62, 62′ to be fixed in place on the fixing section 31, 32 in a particularly form-fitting manner. Alternatively or additionally, an adhesive, in particular a particularly thermally conductive adhesive, can be used in order to instead or additionally achieve a cohesive attachment of the fixing elements 61, 61', 62, 62' to the fixing section 31, 32, which above all enables conductive heat transport between the printed circuit board 100, base circuit board 150 and / or cooling element 14 allows.

By fixing the fixing elements 61, 61', 62, 62' in a T-shaped fixing recess 35, 36, with respect to a section with a cutting plane parallel to the height direction h and to the longitudinal direction I as in FIG 5a shown, a deflection or vibration of the circuit board holder 10 in the vertical direction h and in the longitudinal direction I can advantageously be restricted or avoided, whereby a particularly vibration-resistant circuit board holder 10 is provided.

5b shows a sectional view of a portion of a printed circuit board holder 10 with a sectional plane parallel to the width direction b and the longitudinal direction I, so that another view of the first fixing recess 35 can be seen.

The first fixing recess 35 can, in exemplary embodiments and as shown in FIG 5b shown T-shaped. In other words, the first fixing recess 35 in the first fixing section 31 can be configured so that it is formed in sections in a section with a section plane parallel to the width direction b and the longitudinal direction I, with the first fixing recess 35 in the width direction b within the first fixing section 31 a has a greater extent in the longitudinal direction I than in the width direction b towards the outside of the first fixing section 31.

By fixing the fixing elements 61, 61', 62, 62' in a T-shaped fixing recess 35, 36, with respect to a section with a cutting plane parallel to the width direction b and to the longitudinal direction I as in FIG 5a shown, a deflection or vibration of the circuit board holder 10 in the width direction b and in the longitudinal direction I can advantageously be restricted or avoided, whereby a particularly vibration-resistant circuit board holder 10 is provided.

How through the 5a and 5b clarified, the first fixing recess 35 can be T-shaped independently of one another in two sectional planes, which means that a fixing element 35 can be easily installed or fixed, and at the same time advantageously a deflection or vibration of the circuit board holder 10 in the height direction h, width direction b and can be restricted or avoided in the longitudinal direction I, whereby a particularly vibration-resistant circuit board holder 10 is provided.

The above description with regard to the first fixing cutout 35 in connection with the first fixing element 61 applies to all fixing cutouts 35, 35′, 36, 36′ and fixing elements 61, 61′, 62, 62′.

Furthermore shows 5b for example, that a stiffening rib 80 can extend in the longitudinal direction I up to the fixing recess 35 . Since the fixing element 61 is fixed to the fixing recess 35 of the first fixing section 31, a stiffening rib 80, which extends to the fixing recess 35, enables an advantageous flow of forces, in particular between the fixing elements 61 and 62 or on the opposite side in the width direction between the fixing elements 61 'and 62', so that the force can be directed around the printed circuit board 100, which is arranged with the contact section 110 in the receptacle 24, and transmission of vibrations to the printed circuit board 100 can be restricted or avoided.

6a shows a side view of a portion of a printed circuit board holder 10. It is particularly clear that a tool opening axis 45, along which a tool opening 44 extends in a tool feedthrough element 42, in particular in a cylindrical manner, is different from an unlocking recess axis 73, along which an unlocking recess 72 extends in a Tool insertion element 70 extends, in particular extends cylindrically. The difference between the tool opening axis 45 and the unlocking recess axis 73 essentially ensures the elastic deformation of the elastically deformable locking device 40, on which the locking projection 46 is arranged, when a tool is passed through the tool opening 44 and inserted into the unlocking recess 72.

6b shows an oblique view of a printed circuit board holder 10. In particular, in 6b two opposing locating members 52 of a pair of locating members 50 can be seen, each locating member 52 having a locating projection 54 extending towards the opposite locating member 52, the locating projections 54, 54 configuring a positioning gap in width direction b.

As in 6b shown, the positioning elements 52 each have a positioning chamfer at the upper end in the height direction b and facing the respective opposite positioning element 52, which facilitates the arrangement of a printed circuit board 100, in particular a contact section 110 of a printed circuit board 100, in the receptacle 24.

Furthermore shows 6b that the positioning projections 54 taper in the extension to the opposite positioning projection 54 following in the height direction h. In other words, the positioning projections 54 have inclined surfaces on upper and lower sides thereof, in particular surfaces inclined to one another, so that the positioning projections 54 each have a decreasing cross section following the extension in the width direction.

Due to the tapering positioning projections 54, or the decreasing cross section of the positioning projections 54 along the extension in width direction b, the inclined surfaces on the upper sides of the positioning projections 54 allow additional facilitation, in particular through a guide, when arranging the printed circuit board 100, in particular a contact section 110 of a printed circuit board 100 in the receptacle 24. Since the underside of the positioning projections 54 is also provided with an inclined surface, blocking or wedging when the printed circuit board 100 is removed from the receptacle 24 is prevented. Thus, by providing the positioning protrusions 54 with inclined surfaces on their upper and lower surfaces, the mounting and removing of the circuit board 100 is advantageously facilitated, and the mounting and removing of the circuit board 100 is prevented from being damaged.

7 shows a sectional view of a portion of a printed circuit board holder 10 with a sectional plane parallel to the vertical direction h and the longitudinal direction I. As in FIG 7 shown, the locking projection 46 extends at its tip facing the receptacle 24 in the longitudinal direction I with an underside that is essentially parallel to the longitudinal direction I. Due to the underside running essentially parallel to the longitudinal direction I, the locking projection 46 enables a locking effect in a locking engagement in a locking recess 120 of a circuit board 100, in particular a locking effect with regard to a movement of the circuit board 100 disengaging from the engagement of the locking projection 46 a enables a particularly secure arrangement of the printed circuit board 100 in the receptacle 24, with movement of the printed circuit board 100 in the vertical direction h being restricted or avoided in particular.

Furthermore, in 7 shown by way of example that the tool insertion element 72 can have an unlocking recess 72 which is configured as a blind hole, as a result of which damage to a base circuit board 150 can advantageously be avoided during an unlocking process using a tool.

In addition, shows 7 that the unlocking recess axis 73 of the unlocking recess 72 can run essentially parallel to the tool opening axis 45 of the tool opening 44, the unlocking recess axis 73 being arranged in the longitudinal direction I away from the receptacle 24 at a distance from the tool opening axis 45. The elastically deformable locking device 40 can thus be elastically deformed in the longitudinal direction I away from the receptacle 24 in order to unlock the printed circuit board 100 . The distance between the unlocking recess axis 73 and the tool opening axis 45 in the longitudinal direction I can be, for example, in the range from about 1 mm to about 12 mm, and preferably in the range from about 4 mm to about 9 mm.

8th shows an oblique view of a sectional representation of a partial area of a printed circuit board holder 10.

8th clarifies the preferred configuration of the positioning element 52 with the positioning projection 54, as in connection with FIG 6b described, so that the description of the figures 6b is referenced.

Further clarified 8th the preferred configuration of the locking projection 46, the tool opening 44 with the tool opening axis 45 and the unlocking recess 72 with the unlocking recess axis 73, as in connection with 7 described, so continue to the description of the figures 7 is referenced.

9a shows a view of a first sectional illustration through the elongated receiving body 20 of a printed circuit board holder 10 with a sectional plane parallel to the width direction b and the height direction h. 9a first shows an exemplary subdivision of the elongate holding body 20 in the height direction h, wherein a region of the elongate holding body 20 which is essentially configured to laterally surround the contact region 110 of a printed circuit board 100 in the width direction b is a clamping section 25, and a region of the elongate holding body 20, which is a support section 26 which is essentially in the vertical direction h below the clamping section 25 .

Furthermore shows 9a the receptacle 24, which in particular defines a hollow space or a cavity in order to receive a lower section of a printed circuit board 100, in particular a contact section 110 of a printed circuit board 100 therein. The receptacle 24 can in particular in section with a section plane in the height direction h and in the width direction b, as in FIGS 9a and 9b shows can be configured in a substantially U-shape or V-shape. The receptacle 24 can, for example, extend at the same height as the clamping area 25 of the elongated receptacle body 20 . The receptacle 24 can also have an insertion chamfer at the upper ends of the sides which extend essentially parallel to sides of a circuit board 100 in order to facilitate the insertion of a circuit board 100 into the receptacle 24 .

Furthermore, the receptacle 24 may have a receptacle floor configuring a surface or portion up to which the circuit board 100 may be inserted into the receptacle 24 or the elongate receptacle body 20 . The receiving base can in particular extend essentially parallel to the width direction b and to the longitudinal direction I of the elongated receiving body. Alternatively, the receiving base can be configured in a contoured manner, that is to say the receiving base can in particular have a contour. The receiving floor can also be located in particular at a height which separates the clamping section 25 from the support section 26 in the vertical direction h. In particular, the receiving floor can be at a height which precisely separates the clamping section 25 from the supporting section 26 of the elongated receiving body 20 in the vertical direction h.

9a shows first in particular a thin-walled section 27 of the elongate receiving body 20 in contrast to a thick-walled section 28, as exemplified in FIG 9b shown.

The thin-walled section 27 is recessed in sections in the area of the clamping section 26 with respect to the thick-walled section 28, thereby providing a space for arranging a contact element 18, which is configured to contact a contact section 110 of a printed circuit board 100 and optionally also to clamp, and configured a base circuit board 150 is to be contacted at a lower end of the elongated receiving body 20 . In other words, the thin-walled Section 27 has a geometry that is recessed in the width direction b in relation to the thick-walled section 28 in order to arrange a contact element 18 which makes contact or makes contact with both a contact section 110 of a circuit board 100 and a base circuit board 150 .

As in the 9a and 9b shown, the elongated receiving body 20 has a large number of alternating thin-walled sections 27 and thick-walled sections 28, so that advantageously a large number of contact elements 18, in particular electrical contact elements 18, for contacting a contact section 110 of a printed circuit board 100 can be stably positioned in the gaps between two Thick-walled sections 28 result, are arranged. A large number of contact elements 18 can thus be arranged stably on the elongated receiving body 20 .

Furthermore, the alternating thin-walled sections 27 and thick-walled sections 28 of the elongated receiving body 20 can avoid excessive material accumulations of injection-molded material, as a result of which possible distortion when the injection-molded material cools or solidifies can be prevented or reduced.

By preferably arranging a pair of stiffening ribs 80 on both outer sides of the elongated receiving body 20, in particular the opposite outer sides of the elongated receiving body 20 in the width direction b, the vibration resistance and rigidity of the printed circuit board holder 10 can be advantageously increased.

Will, as in the 9a and 9b shown, the stiffening ribs 80 are arranged in the region of the support section 26 of the elongate receiving body 20, the stiffening ribs 80 initially allow a center of gravity of the circuit board holder 10 to be kept low in the height direction h, so that the circuit board holder 10 continues to be advantageously configured in a vibration-proof and rigid manner.

In addition, the arrangement of the stiffening ribs 80 in the area of the support section 26 of the elongate receiving body 20 allows the material flow of injection-molded material to be maintained during the injection molding process, especially in a thin-walled section 27 of the elongate receiving body 20, and enables more uniform cooling. Consequently, the stiffening ribs 80, which are arranged in the area of the support section 26 or adjacent to the support section 26, make it possible for the printed circuit board holder 10 to be configured in a particularly vibration-resistant and rigid manner and at the same time to be manufactured with true shape, i.e. with only little or no distortion , In particular can be injection molded.

9b shows a further view of a first sectional illustration through the elongated receiving body 20 of a printed circuit board holder 10 with a sectional plane parallel to the width direction b and the height direction h. 9b shows in particular a thick-walled section 28 of the elongate receiving body 20 in contrast to the thin-walled section 27, as exemplified in FIG 9a shown.

In 9b Individual contact elements 18 are shown, which are configured as already described above, both a contact section 110 of a circuit board 100, and a base circuit board 150 to contact or to connect contacting. As in 9b indicated, the contact elements 18 can additionally be configured to clamp the contact section 110 of the printed circuit board 100, ie to press against the contact section 110 of the printed circuit board 100 with a prestress in the width direction b.

Furthermore shows 9b a section through the stiffening ribs 80, each stiffening rib 80 having a substantially trapezoidal shape in a cross section or a section with a sectional plane parallel to the height direction h and width direction b. In particular, the stiffening rib 80, as in 9b shown, be configured with a base relative to the trapezoidal shape toward the outside of the elongate accommodating body 20, particularly an outside in the width direction b of the elongate accommodating body 20. In the width direction b opposite the base, the stiffening rib 80 has a shoulder section 82 which extends essentially parallel to the height direction h. As in 9b shown, the stiffening rib 80 can be configured in a section with a section plane parallel to the height direction h and width direction b to taper in the extension in the width direction towards the shoulder section 82, in particular from both in the height direction h above and in the height direction h below. In other words, the upper side surface of the trapezoidal shape of the stiffening rib 80 following the width direction b from the outside of the elongated receiving body 20 can be configured to be inclined downward, and the lower side surface of the trapezoidal shape of the stiffening rib 80 following the width direction b from the outside of the elongated receiving body 20 , be configured inclined upwards. The above-described configuration of the trapezoidal shape of the stiffening rib 80 in a section with a section plane parallel to the height direction h and width direction b can advantageously improve a material flow of injection-molded material during an injection molding process, whereby possible distortion of the circuit board holder 10 is reduced or avoided.

An advantageous conductive heat transfer between the first fixing elements 61, 61' and the cooling element 14 can thus be provided. Since the fixing elements 61, 61' are configured to be fixed to a base circuit board 150, an advantageous conductive heat transfer between the base circuit board 150 and the cooling element 14 can accordingly be provided.

The cooling element connection section 16, as in 10 shown, can in particular be configured to touch the first fixing elements 61, 61' in the state of arrangement on the circuit board holder 10, in particular to touch an upper side in the height direction h of the first contour regions 67, 67' of the first fixing elements 61, 61'.

The one or more cooling fin(s) 15 can be configured to extend in the width direction b from the cooling element 14 to a circuit board 100 and optionally contact the circuit board 100 in a state arranged in the receptacle 24 . A direct contact of the printed circuit board 100 with one or more cooling fins 15 provides an advantageous direct conductive heat transfer from the printed circuit board 100 to the cooling element 14 . Accordingly, using the cooling element 14, as in 10 shown, an advantageous cooling of the circuit board 100 can be provided. Since, as described above, the cooling element 14 also has a conductive heat transfer to the base circuit board 150, a conductive heat transfer can consequently be provided between the base circuit board 150 and the circuit board 100, depending on the temperature gradient, a heat conduction from the circuit board 100 to the base circuit board 150, a heat conduction from the base circuit board 150 to the circuit board 100, or from the base circuit board 150 and the circuit board 100 each to the cooling element 14 are provided.
