Description

[Technical Field]

[0001] The present invention relates to a housing assembly for an electrical connector, the housing assembly comprising a shielding sleeve and at least one contact sleeve module inserted into the shielding sleeve and secured to the shielding sleeve by frictional engagement in an assembled state. [Background technology]

[0002] In electrical connectors, such housing assemblies are used for shielding to reduce or eliminate electromagnetic interference.

[0003] Electrical connectors are typically provided with an outer housing that acts as a shield and into which a respective contact sleeve for each individual cable is inserted. The cable shields are conductively connected to the contact sleeves, and at least one contact sleeve is spot-welded to the outer housing. This type of manufacturing is very complex, and good electrical contact between the contact sleeves and the outer housing is not necessarily guaranteed. Summary of the Invention [Problem to be solved by the invention]

[0004] The invention is therefore based on the object of improving the housing assembly mentioned at the beginning in such a way that it is easier to manufacture and allows a more reliable contact between the shield sleeve and the contact sleeve module. [Means for solving the problem]

[0005] The present invention first solves this problem by providing a housing assembly for an electrical connector, the housing assembly comprising a shielding sleeve made of a conductive material, the shielding sleeve having a central receptacle axially penetrating the shielding sleeve for receiving at least one shielded cable, at least one contact sleeve module made of a conductive material inserted into the central receptacle, the contact sleeve module having at least one passage opening for the at least one shielded cable, the contact sleeve module having at least one contact portion for contacting the shield of the at least one shielded cable, the contact sleeve module being fixed in the shielding sleeve by frictional engagement in the assembled state.

[0006] This solution simplifies assembly, since welding can be omitted. At the same time, a good electrical connection is ensured by the frictional engagement between the shielding sleeve and the at least one contact sleeve module. The shielding sleeve is used primarily for electromagnetic shielding.

[0007] The invention can be further improved by the following features, each of which is advantageous on its own, independent of one another and which may be combined with one another as needed.

[0008] In an advantageous embodiment, the shielding sleeve and / or at least one contact sleeve module of the housing assembly may be made of metal, such as steel, copper, or aluminum, to ensure reliable electrical contact between the at least one contact sleeve module and the shielding sleeve. Sheet metal may be used for these components to ensure good formability during manufacturing and lightweight components. Alternatively, the shielding sleeve and / or at least one contact sleeve module may be made of a plastic material that contains metal and / or is electrically conductive.

[0009] The shielding sleeve may be deep drawn, which allows for great flexibility in terms of shape, material and size at low part cost.

[0010] In an advantageous embodiment, the shielding sleeve may comprise recesses and / or ridges or protrusions on its peripheral outer surface. The recesses and / or ridges may serve to improve handling and simplify assembly. Alternatively or additionally, the recesses and / or ridges may serve as guides that simplify positioning of the shielding sleeve in the housing. The ridges and / or recesses may be part of a coding that prevents incorrect insertion of the shielding sleeve. The recesses may, for example, be configured in the form of an axially extending channel, in particular a coding channel, or an axially extending groove. The ridges may be configured as axially extending ribs, in particular a coding rib. Finally, the ridges and / or recesses may form form-fitting or friction-engagement elements that are configured to be engageable with the peripheral housing of the shielding sleeve.

[0011] In one configuration, the shielding sleeve may include an end wall defining a central axial receptacle, the other end of which may be completely open.

[0012] The shielding sleeve may have a tapered portion that narrows in a direction in which the shielding sleeve moves away from the central receptacle. The tapered portion may extend axially to an end wall of the shielding sleeve. The tapered portion may be configured in a step shape and terminate at its smallest diameter at the end wall of the shielding sleeve. This provides a compact design, saves material and space, and particularly increases compatibility with internal and external components of the shielding sleeve.

[0013] In one configuration, at least one contact sleeve module rests against the end wall of the shield sleeve when inserted, particularly with an intermediate wall or transition region facing in the axial direction, in order to achieve electrical contact over as large an area as possible.

[0014] The at least one contact sleeve module may be held in the shield sleeve by press-fit, which is advantageous for high-precision alignment and a play-free connection without the need for any additional fastening elements.

[0015] At least one contact sleeve module may be provided with a plurality of spaced apart projections projecting outwardly from its outer periphery at least in the region that frictionally engages with the shield sleeve.

[0016] The frictional engagement with the shielding sleeve is preferably established by protrusions. The number and shape of the protrusions can be used to precisely adjust the force required to press the at least one contact sleeve module into the shielding sleeve, as well as the size of the contact area and therefore the electrical boundary resistance. In particular, the protrusions can have different heights. They can then be adapted to the shape of the shielding sleeve to ensure a uniform contact force distribution at the individual contact points over the entire circumference.

[0017] The shielding sleeve may be provided with smooth walls in the region of the central receptacle where the shielding sleeve engages with the protrusions of the at least one contact sleeve module through frictional engagement. Alternatively, protrusions may also be provided in the region of the central receptacle where the shielding sleeve engages with the protrusions of the at least one contact sleeve module. In the assembled state of the at least one contact sleeve module, the protrusions of the contact sleeve module may be located between the protrusions of the central receptacle. To avoid surface contact, the regions between the protrusions of the at least one contact sleeve module and / or the protrusions of the central receptacle are preferably flat or smooth.

[0018] In an advantageous embodiment, at least two contact sleeve modules may frictionally engage with each other when inserted into the shield sleeve, such that the contact sleeve modules inserted into the shield sleeve are supported by each other and by the shield sleeve in a direction transverse to the axial direction, and are therefore fixed to each other and to the shield sleeve as a package by frictional engagement.

[0019] At least two of the contact sleeve modules are preferably configured to be identical, which simplifies manufacturing, reduces complexity, and improves frictional engagement. The at least two identical contact sleeve modules may be arranged in a mirror image and / or rotated relationship with respect to one another and may be interlocked with one another. For example, two, three, four, or five preferably identically configured contact sleeve modules may be pressed into the central receptacle by frictional engagement. However, in other configurations, more than five, for example eight or nine, preferably identical contact sleeve modules, may be inserted into the central receptacle by frictional engagement.

[0020] The at least two contact sleeve modules may be provided with a plurality of spaced apart projections on their outer peripheries, particularly in the region where they frictionally engage with at least one other contact sleeve module.

[0021] The protrusions may be spaced apart from one another in the circumferential direction of the respective contact sleeve module. The protrusions may advantageously be axially elongated and configured to form line contact with the shield sleeve and at least one other contact sleeve module. For example, the protrusions may be configured as a plurality of axially extending ribs in their longitudinal direction. In particular, the ribs may be arranged at equal intervals from one another around the outer periphery of the respective contact sleeve module. The ribs may be formed as rounded or pointed. Axially extending ribs can be easily produced by deep drawing or can be more easily removed from a mold during production.

[0022] In one variant, the outer periphery of the contact sleeve module may be configured to be wavy, where, for example, the crests of the waves may be formed by rounded ribs, while the intervening troughs of the waves are formed by negative shapes, i.e. grooves, having the contours of the ribs and running parallel to them.

[0023] Another alternative may comprise a plurality of protrusions configured as projections on the outer periphery of the contact sleeve module, which then make at least approximately point-like contact with another contact sleeve module and / or the shield sleeve when inserted into the shield sleeve. These embodiments with line and / or point contact ensure a non-surface contact over the entire periphery, which makes it easier to press into at least one contact sleeve module, while at the same time ensuring a long-lasting press fit and improving electrical contact. The protrusions configured as projections may be aligned one behind the other in the axial direction. They therefore correspond to discontinuous ribs in the axial direction.

[0024] When two adjacent contact sleeve modules with protrusions on their outer peripheries abut each other in an assembled state or when inserted into a shielding sleeve, it is preferable that the protrusions of one contact sleeve module be located between the protrusions of the other contact sleeve module. For example, in this case, the waves are arranged in the valleys. As explained above, the valleys do not need to be formed concavely. For example, a smooth or flat valley can improve electrical contact due to only line or point contact.

[0025] In an advantageous embodiment, the common outer contour formed by the contact sleeve modules inserted into the shield sleeve may be configured to be complementary to the inner contour of the shield sleeve in a plane transverse to the axial direction. In particular, the common outer contour may be pressed into the inner contour of the shield sleeve to form a frictional engagement. For this purpose, the common outer contour preferably has a larger size compared to the inner contour of the shield sleeve or compared to the central receptacle.

[0026] The outer contour of the contact sleeve module may at least partially rest against the inner contour of the shielding sleeve and / or against the outer contour of at least one other contact sleeve module, so that the contact sleeve modules are in contact with each other and with the shielding sleeve over as large an area as possible of their outer peripheries, which configuration makes it possible to reduce the boundary resistance.

[0027] The central receptacle may have an oval or circular cross section. Accordingly, the area of ​​the at least one contact sleeve module that frictionally engages with the shield sleeve may have an arc shape complementary to the oval or circular cross section. The large contact area enhances frictional engagement while providing low electrical boundary resistance.

[0028] On the sides where the contact sleeve modules abut against one another, they may be flat, in particular flat on one side, in order to achieve an improved line contact in one configuration. In particular, a protrusion of one of the contact sleeve modules may abut against a corresponding complementary surface of at least one other contact sleeve module. Preferably, the protrusion of a contact sleeve module abuts against a particularly flat or planar region of the other contact sleeve module. The cross section may be rotationally symmetrical and may have a partially wavy configuration. The base region of at least one contact sleeve module in the axial direction may, for example, have an approximately sectorial shape, preferably with rounded corners.

[0029] The contact portions of the contact sleeve module may be configured in the shape of a hollow cylinder, for example as hollow cylindrical extensions or stubs, to ensure high stability and simple connection for shielding cables. The contact portions may, for example, protrude axially from an intermediate wall of the contact sleeve module. To simplify assembly, the hollow cylindrical extensions or stubs may protrude from the shielding sleeve when the contact sleeve module is inserted.

[0030] The contact sleeve module may include a clamping portion having an outer periphery with a region for frictionally engaging with the shield sleeve and / or another contact sleeve module. The clamping portion may include a protrusion for forming the frictional engagement. When the contact sleeve module is assembled, the clamping portion is disposed on the shield sleeve or its central receptacle. The clamping portion may protrude axially from the intermediate wall in the form of a collar.

[0031] The contact portion of the contact sleeve module preferably has a smaller gap than the clamping portion of the contact sleeve module. The clamping portion may comprise an axially oriented intermediate wall at the transition to the contact portion. In other words, the axially oriented intermediate wall may form the transition between the contact portion and the clamping portion. The intermediate wall may extend annularly around the contact portion and, in particular, may abut against an end wall of the shielding sleeve when the contact sleeve module is inserted into the shielding sleeve. In one configuration, the end wall may form one axial end of the shielding sleeve. In another advantageous configuration, the intermediate wall is spaced apart from the end wall.

[0032] In the end wall, the shielding sleeve may have at least one through-opening through which a contact portion of the contact sleeve module projects, whereby multiple contact portions may project through a single through-opening, or one corresponding contact portion projects through one corresponding through-opening.

[0033] An electrical connector, particularly a multi-pole electrical connector, including a housing assembly as described above may have at least one cable extending through the central receptacle and the contact portions, the shield of which is conductively connected to the contact portions.

[0034] The contact portion may be in direct contact with the shield of the cable passing through it, for example the contact portion may be crimped onto the shield.

[0035] In another configuration, the electrical connector includes a cable sleeve that may be pressed or squeezed onto the contact portions of the contact sleeve module, preferably directly connected to the shield of the cable.

[0036] In one variation, the point at which the cable sleeve is electrically connected to the shield of the cable may be axially spaced from the point at which the cable sleeve is connected to the contact portion of the contact sleeve module through which the cable passes. In this variation, the cable sleeve represents the electrical connection between the shield and the contact portion. The outer sheath of the cable may be mechanically fixed by the cable sleeve to allow strain relief of the electrical connection.

[0037] The shielding braid of the cable, or equivalently the shielding, may be clamped, in particular crimped, between the cable sleeve and the contact sleeve module, where the cable sleeve may be arranged radially outside or inside the shielding.

[0038] The cable sleeve, shield and contact portion may be connected to one another at a single point by a single crimp connection. Alternatively or additionally, the cable sleeve may be crimped to the shield, which is also axially spaced from the contact portion.

[0039] In a further variant, only the cable sleeve may be crimped onto the contact portion. Instead of a crimp connection between the contact portion and the cable sleeve, a friction-fit connection may be provided. For example, the cable sleeve may be pressed or forced onto the contact portion. Such pressing or forcing may be effected by a shield arranged between the cable sleeve and the contact sleeve module. Alternatively, the connection between the cable sleeve and the contact portion or between the braided shield of the cable and the contact portion may be established by material bonding, for example by soldering and / or welding, and / or by other press-fit, material-bond or form-fit connections.

[0040] In one embodiment, the electrical connector may include a housing assembly and at least two electrical cables. Each cable or conductor may extend through the central receptacle and the contact portions. The shield of each cable may be partially exposed and may be connected to one of the contact portions.

[0041] To assemble the electrical connector, at least two cables may first be connected to the at least two contact sleeve modules outside the shielding sleeve before the at least two contact sleeve modules are inserted together into the shielding sleeve and firmly attached to the shielding sleeve and to each other by frictional engagement.

[0042] Finally, the present invention relates to a set comprising at least two electrical connectors having identical contact sleeve modules, one of the at least two connectors comprising a cable that may have a different cable diameter than the cable of another one of the at least two connectors.

[0043] The invention will now be described by way of example only, by way of an embodiment, with reference to the drawings, in which elements that correspond to one another in terms of function and / or structure bear the same reference signs.

[0044] In accordance with the above description, a feature of an embodiment may be omitted if the technical effect associated with this feature is not important for a particular application. Conversely, a feature not already present there may be added to an embodiment in accordance with the above description if the technical effect of the feature to be added is important for a particular application.

[Figure 3]FIG. 1 is a top view of a housing assembly having two contact sleeve modules. [Figure 4] FIG. 1 is a top view of a housing assembly having four contact sleeve modules. [Figure 5] FIG. 2 is a diagram of the electrical connector in a partially assembled state. DETAILED DESCRIPTION OF THE INVENTION

[0046] FIG. 1 shows a housing assembly 1 shown with a shield sleeve 2 and two contact sleeve modules 4 .

[0047] The shielding sleeve 2 may be substantially hollow cylindrical and may comprise a central receptacle 6. The central receptacle 6 may be open on one side and may comprise an end wall 8 on the other side with at least one, here for example two, passage openings 10. The contact sleeve modules 4 may protrude from the passage openings 10. The end wall 8 may thereby form an end of the shielding sleeve 2. The number of passage openings 10 in the end wall may vary. For example, there may be only one passage opening 10 in the end wall 8, or equally there may be at least two passage openings 10.

[0048] The central receptacle 6 passes through the shielding sleeve 2 along an axial direction 12. Along this direction 12, from the open side of the central receptacle 6 towards the end wall 8, the shielding sleeve 2 may be provided with a tapered section 14. This tapered section 14 may connect the various assembly interfaces with one another. The diameter of the tapered section 14 may preferably gradually decrease along the axial direction 12 towards the end wall 8. In the region of its smallest diameter, the tapered section 14 may rest against the contact sleeve module 4.

[0049] The shielding sleeve 2 may be of one-piece construction. The shielding sleeve 2 and / or the contact sleeve module 4 may be made, for example, from a metal-containing material, in particular from a metal and / or metal-containing plastic material, and may be electrically conductive. The shielding sleeve 2 and / or the contact sleeve module 4 may be made from sheet metal, in particular by deep drawing.

[0050] The basic geometry and / or dimensions of the shielding sleeve 2 can be easily adapted to any number of cables 16. For this purpose, for example, only the shape of the end walls 8 need to be changed and / or the diameter of the shielding sleeve 2 need to be changed.

[0051] The shielding sleeve 2 may be provided on the outer surface of its periphery 17 with recesses 18 and / or ridges 20, which are useful for easy handling, easy assembly, particularly easy positioning, and stable fixation. In this case, the recesses 18 and / or ridges 20 may extend axially between the central receptacle 6 and the tapered portion 14. In particular, the recesses 18 and / or ridges 20 may function as guides to facilitate positioning of the shielding sleeve 2 in a housing (not shown). The ridges 20 and / or the recesses 18 may also be part of a coding to prevent incorrect insertion. Furthermore, the recesses 18 and / or ridges 20 may be used as form-fitting or friction-engagement elements that can engage with the housing of the shielding sleeve 2.

[0052] At least one contact sleeve module 4 is inserted into the shielding sleeve 2 with its cylindrical contact portion 22 protruding from at least one passage opening 10 in the end wall 8. According to a further configuration, the end wall 8 may be spaced apart from the at least one contact sleeve module 4 but may abut against it. The at least one contact sleeve module 4 may advantageously be made from metal, although sheet metal may be selected to take advantage of the same advantages of easy formability and light weight. Alternatively, the contact sleeve module 4 may be made from a conductive plastic material, for example one containing metal.

[0053] In the assembled state, the at least one contact sleeve module 4 is fixed to the shielding sleeve 2 by frictional engagement, in particular exclusively by frictional engagement. In an advantageous embodiment, the at least one contact sleeve module 4 is held in the shielding sleeve 2 by press fit.

[0054] 2, two contact sleeve modules 4 are shown as an example, protruding through two passage openings 10 in the shield sleeve 2. However, the number of contact sleeve modules 4 is arbitrary. If multiple contact sleeve modules 4 are present, at least two of the contact sleeve modules 4 may be configured to be identical in order to reduce the number of different parts.

[0055] Preferably, at least two contact sleeve modules 4 are connected by frictional engagement to the shield sleeve 2. The contact sleeve modules 4 may also be frictionally engaged with each other.

[0056] In Figure 2, the contact sleeve modules 4 are shown abutting each other and in this configuration are inserted, particularly pushed, or here equivalently, pressed together as a package into the shielding sleeve 2 (Figure 1). In this embodiment, the contact sleeve modules 4 are each generally bell-shaped in an axial plane (parallel to the axial direction 12). In the direction transverse to the axial direction 12, the contact sleeve modules 4 may have various geometric shapes, such as circular, sector-shaped, or kidney-shaped. The contact sleeve modules 4, configured here to be identical, may be inserted into the shielding sleeve 2 rotated relative to each other about an axis extending parallel to the axial direction 12.

[0057] The contact sleeve module 4 may comprise a clamping section 24 that transitions into one or more stub-shaped, in particular hollow-cylindrical, contact sections 22. The contact sections 22 may have a smaller gap 26 than the clamping section 24. An intermediate wall (or equivalently, a transition region) 28 facing in the axial direction 12 is formed as a transition between the clamping section 24 and the contact sections 22. In the assembled state of the contact sleeve module, the intermediate wall 28 may abut against the end wall 8 of the shielding sleeve 2. Advantageously, the intermediate wall 28 may be spaced apart from the end wall 8. The intermediate wall 28 may extend annularly around the contact sections 22, as shown in FIG. 2. The clamping section 24 may be formed, for example, by a collar 29 that projects axially from the intermediate wall 28 in one direction, while the contact sections 22 project axially from the intermediate wall 28 in the opposite direction. The intermediate wall 28 may be slightly inclined with respect to the axial direction 12.

[0058] The contact sleeve module 4 may comprise a plurality of protrusions 30 spaced apart from one another in the circumferential direction, at least in the region of its outer periphery 31 where it contacts the shield sleeve 2. For example, the clamping portion 24 comprises a protrusion 30 extending along the axial direction 12 (FIG. 1) and forming a line contact with the shield sleeve 2 and at least one other contact sleeve module 4. In particular, the protrusion 30 may be configured as a rib protruding outward in the radial direction 34. The outer contour of the contact sleeve module 4, in particular the clamping portion 24, may be configured wavy, as shown in FIG. 3. Furthermore, the clamping portion 24 may only be wavy in part. Another alternative may be protrusions as the protrusions 30, which then establish substantially point-like contact with the shield sleeve 2 and at least one other contact sleeve module 4.

[0059] In order to form the largest possible contact area, the outer contour of the clamping part 24 or the outer contour formed by the clamping parts 24 together may be configured to be complementary to the inner contour 35 (FIG. 4) of the shielding sleeve 2. The outer contour of the clamping part 24 of one contact sleeve module 4 may be complementary to the outer contour of the clamping part 24 of another contact sleeve module 4, at least in the area 37 (FIG. 3) where they contact, and may likewise be configured to be complementary to the outer contour 24 of the other abutting contact sleeve module 4, in order to form a large contact area there as well with the inner contour 35 of the shielding sleeve 2 as well as with each other.

[0060] The area 37 where the contact sleeve modules 4 come into contact with one another may be flat, in particular flat on one side. In particular, the protrusion 30 of one contact sleeve module 4 may at least partially abut against a flat surface of another contact sleeve module 4. The outer contour of each clamping portion 24 may be rotationally symmetrical. In particular, when several contact sleeve modules 4 abut against one another, the protrusion 30 of one contact sleeve module 4, in particular the clamping portion 24, may be arranged between two protrusions 30 of another contact sleeve module 4 that are spaced apart in the circumferential direction 32. The protrusion 30 of one contact sleeve module 4 may abut against a surface that is as flat as possible, in particular a non-concave surface, between the two spaced apart protrusions 30 of another contact sleeve module 4.

[0061] The spaced apart protrusions 30 of a contact sleeve module 4, together with flat portions disposed therebetween or portions of a shape complementary to the protrusions 30 of other contact sleeve modules 4, may form a wave shape around the entire circumference of the clamping portion 24. The protrusions 30 form the positive radial outward deflection of the wave, while the flat portions or portions complementary to the protrusions 30 form the dips or troughs of the wave, i.e., the negative radial inward deflection.

[0062] The contact sleeve modules 4 may all have a shape complementary to the internal cross section of the shield sleeve 2, for example, an arc shape.

[0063] Two variants of the contact sleeve modules 4 are shown in Figures 3 and 4, each showing a top view of the central receptacle 6 of the shielding sleeve 2. An embodiment with two contact sleeve modules 4 is shown in Figure 3, and an embodiment with four contact sleeve modules 4 is shown in Figure 4. The number of contact sleeve modules 4 can be variably adapted to the respective cable 16 used and may be extended to, for example, eight or nine contact sleeve modules 4.

[0064] The contact sleeve modules 4 rest with their clamping portions 24 partially against the interior 35 of the shielding sleeve 2 and against each other. In the area 37 where the contact sleeve modules 4 contact each other, the clamping portions 24 are also complementary to each other. A shielded cable 16 is guided through each of the openings 36 of the contact sleeve modules 4.

[0065] The components of a multi-pole electrical connector 38 having a housing assembly 1 and two shielded cables 16 are shown by way of example in a partially assembled state in FIG.

[0066] In an advantageous configuration, the electrical connector 38 may in particular comprise at least one cable sleeve 40 which can be pressed or pushed onto the contact portions 22 of the at least one contact sleeve module 4 .

[0067] The shield 42 of the cable 16 may be connected to the contact portion 22 of the contact sleeve module 4 via at least one cable sleeve 40. The shield 42 of the cable 16 may be clamped between the cable sleeve 40 and the contact portion 22 of the contact sleeve module 4.

[0068] The cable sleeve 40 may have a diameter slightly larger than the contact portion 22. Alternatively, the cable sleeve 40 may have a diameter smaller than the contact portion 22 and may be pressed onto the contact portion 22 to clamp the shield 42 of the cable 16.

[0069] The shields 42 of the cables 16 may be connected by at least one crimp connection.

[0070] In a further configuration, a cable 16 having a small cable diameter may be crimped directly onto the contact portion 22 of the contact sleeve module 4 .

[0071] The electrical connector 38 may comprise a contact element carrier 44 to which the cables 16 are connected, for example, by socket contacts. The contact element carrier 44 with the socket contacts may then be used as a connecting link to an external interface. The contact element carrier 44 comprises the same number of receptacles 46 as there are cables 16 present.

[0072] The contact element carrier 44 may be used as an assembly aid for pressing the contact sleeve module 4 into the shielding sleeve 2. Assembly aids similar in shape to the contact element carrier 44 are also conceivable for pressing the contact sleeve module 4 into the shielding sleeve 2.

[0073] In this embodiment, the shields 42 of the cables 16 are each fitted over the contact portions 22 of the contact sleeve modules 4. The cables 16 are each connected to the contact portions 22 of the contact sleeve modules 4 by means of cable sleeves 40 which are each pressed onto the shields 42 and contact portions 22. The friction fit connection of the contact sleeve modules 4 to the shield sleeves 2 establishes current transmission.

[0074] In an advantageous configuration, the cables 16 may be connected to the contact sleeve modules 4 only via their respective contact portions 22, and one cable sleeve 40 may be used for this purpose in each case. The contact sleeve modules 4 connected to the cables 16 may then be positioned adjacent to one another and inserted together into the shielding sleeve 2 and fixed in place by frictional engagement.
