Description

[Technical field]

[0001] The present invention relates to a shielded spring shell for a high current plug-in connection having at least one contact tab for contacting a mating connector. [Background technology]

[0002] Shielding is essential to ensure the electromagnetic compatibility of a system. Shielding is used to direct electric and / or magnetic fields away from the system or to protect the environment from electric and / or magnetic fields emanating from the system. To ensure shielding in a plug-in system during operation, and especially for the shielding of the mating connector, it is important that the shield of the connector is in continuous contact with the mating connector, but this proves difficult as high stresses in use, e.g. vibrations, can cause contact breakage. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE PRESENT EMBODIMENT It is therefore an object of the present invention to create a shielded spring shell that ensures continuous contact with a mating connector even under high stresses such as vibration. [Means for solving the problem]

[0004] According to the invention, this object is achieved by the shield spring shell mentioned at the outset, the contact tab having two spring parts adjacent to a fillet, one of the two spring parts being configured as a radial spring elastic at least in the radial direction and the other of the two spring parts being configured as an axial spring elastic at least in the axial direction.

[0005] By means of the solution according to the invention, the at least one contact tab with its two spring parts can compensate for both radial and axial movements between the connector and the counter connector, for example due to vibration stresses. It can then be ensured that contact to the counter connector is ensured even when radial and axial vibration stresses occur simultaneously.

[0006] At least radially elastic or at least axially elastic means within the meaning of the present application that the radial springs can be primarily radially elastic, i.e. that their spring strength can be lowest in the radial direction, or that the axial springs can be configured to be primarily axially elastic, i.e. that their spring strength is lowest in the axial direction. Of course, the radial springs can also be axially elastic or the axial springs can also be radially elastic, and the respective springs can be elastically deflected in the axial or radial direction, respectively, for example by static friction at a pressure surface arranged on the counter connector.

[0007] Below, further developments are described which are advantageous within their own scope and which can be combined with one another independently if desired.

[0008] The axial spring may comprise an axially pointing yielding contact surface and / or the radial spring may comprise a radially pointing yielding contact surface. Compensation of the relative movements between the connector and the mating connector in the axial and / or radial directions, respectively, may be further optimized by the yielding contact surfaces.

[0009] For example, the at least one contact surface may be formed on a bulge of the contact tab. Preferably, at least the axial spring comprises a portion bulging convexly in the axial direction toward the pressing surface of the mating connector in order to preload the axial spring in a direction toward the pressing surface of the mating connector, thereby ensuring a high contact force.

[0010] The convex bulge can in particular be a circular arc bulging in the direction towards the mating connector between two parts of the contact tab that are colinearly arranged, or it can be formed by bending back an axial spring, in particular a free end of the axial spring, in the direction towards a fillet.

[0011] To obtain a larger preload radially with the radial spring and axially with the axial spring, the fillet angle between the radial spring and the axial spring can be at most about 90°, preferably between about 45° and about 90°.

[0012] The shield spring shell can include a shell body extending along a longitudinal axis with the at least one contact tab extending away from at least one end of the shell body along the longitudinal axis. The at least one contact tab can extend substantially away from the longitudinal axis, at least prior to insertion into the connector, such that the contact tab can be more easily pushed into a receptacle of the connector.

[0013] Alternatively or additionally, at least one contact tab can be bent back from an edge of the end of the shell body, particularly radially outward along the longitudinal axis. The radial spring can then be arranged substantially along the longitudinal axis parallel to the exterior surface of the shell body and can be deflected radially towards or away from the shell body. Thus, the shell body can also act as a stop to limit the movement of the radial spring in the radial direction.

[0014] To further increase the spring force of the radial spring, the radial spring can be provided with a spring tab supportable on the exterior surface of the shell body, extending in a direction towards the exterior surface of the shell body, so that the radial spring is not only radially determined by the arc between the radial spring and the edge of the shell body, but is also improved by the spring tab.

[0015] In this case, the contact tab may be bent radially outward at the end of the radial spring facing away from the edge, thus forming a fillet, with the axial spring extending substantially radially outward from the fillet.

[0016] According to a further advantageous embodiment, the shield spring shell can be configured to contact two different mating connectors, for which purpose the shield spring shell can be provided with at least one contact tab at each of its ends arranged oppositely along the longitudinal axis.

[0017] The contact tabs at the oppositely disposed ends may be structurally identical to the contact tabs at the respective other ends. However, the contact tabs may extend substantially along the longitudinal axis at at least one end away from the respective edges before the shield spring shell is inserted into the connector receptacle to simplify insertion of the contact tabs into the receptacle. At the other end, at least one contact tab may be bent back before insertion into the connector receptacle. As a result, the contact tabs may each protrude from the oppositely disposed ends of the connector receptacle and each may contact a mating connector.

[0018] To optimize the contact of the shield spring shell with the mating connector, several contact tabs can be arranged along the longitudinal axis of the shell body, at least at one end, in particular at both ends, preferably coronally. The contact tabs can be spaced apart from one another in the circumferential direction, so that slots are formed between circumferentially adjacent contact tabs. Each contact tab can then be deflected independently of the adjacent contact tabs.

[0019] When several contact tabs are located at both ends of the shield spring shell, the arrangement and / or number of contact tabs at one end can be independent of the arrangement and / or number of contact tabs at the other end, such that the contact tabs at each end can be optimized for a complementary mating connector.

[0020] The shield spring shell can be formed integrally, preferably as a single component, so that the shield current can be conducted therethrough without additional contact resistance. The shield spring shell can be formed, for example, as a stamped bent part, which allows for cheap and fast production, especially in large quantities. For example, a sheet of metal can be stamped and rolled to form the shell body. The shape of the shield spring shell can be fixed in the circumferential direction between the oppositely arranged edges of the sheet of metal by a positive fit, especially a dovetail connection. For example, the oppositely arranged edges can be provided with interlocking teeth that create a positive fit.

[0021] The connector for mating with at least one mating connector may comprise a base body extending along a longitudinal axis, the connector comprising a receptacle into which a shield spring shell according to one of the previous embodiments is inserted, at least one contact tab protruding from the receptacle, in particular along the longitudinal axis.

[0022] A connector can be, for example, an adapter element that electrically couples two mating connectors to one another. For example, a connector can be a connector interface that can be inserted into an opening in an element to be actuated, for example a printed circuit board, and establishes contact with this element.

[0023] The at least one contact tab can be bent back around the wall of the receptacle at at least one end of the shield spring shell. In particular, the at least one contact tab can be bent back radially outwardly around the wall of the receptacle only after the shield spring shell has been inserted into the receptacle. As a result, the at least one contact tab, in particular the radial spring of the at least one contact tab, can be supported by the wall. The axial spring can extend radially outwardly from the wall as a free end of the contact tab.

[0024] The connector may include a radially projecting collar to separate a front plug-in portion for plugging into a first mating connector and a rear plug-in portion for plugging into a second mating connector. For example, the collar may project radially beyond the opening in the mating connector, thereby preventing the connector from being inserted deeper into the opening.

[0025] The receptacle may preferably be formed by a gap between the base body and the collar in the radial direction, whereby the inserted shield spring shell may be held between the base body and the collar. The shield spring shell, the base body and the collar may mainly have a substantially rotationally symmetric shape, for example a cylindrical shape. The shield spring shell may be wrapped coaxially around the exterior surface of the base body.

[0026] To ensure that the connector can be produced as quickly and cheaply as possible, the collar can be molded onto the base body. The collar and the base body can be integrally formed as a single housing part, for example by injection molding. The housing part can preferably be formed from an electrically insulating material, in particular a plastic material, so that electric shocks caused by accidental contact with the housing part can be prevented. Depending on the application, the housing part can also be formed from a metallic material.

[0027] The connector may include a rib extending from the base body to the collar to hold the collar to the base body. The ribs may be circumferentially separated from one another, thereby subdividing at least a portion of the receptacle into circumferentially separated chambers. Each chamber may be penetrated by a respective one of the contact tabs at one end of the shield spring shell. Thus, the respective contact tabs may be circumferentially separated from one another, for example by circumferentially deflecting the contact tabs, to prevent pinching of the contact tabs.

[0028] The contact tabs can be circumferentially spaced apart to form slots between the contact tabs into which ribs can be inserted. The ribs can be used not only to connect the collar to the base body or to circumferentially separate the contact tabs, but also as stops to lock the insertion movement of the shield spring shell into the receptacle when an edge of the shield spring shell extending away from at least one contact tab protruding through one chamber strikes the rib along the longitudinal axis.

[0029] When the collar rests stably as flat as possible on the mating connector, the collar on its flat surface facing the mating connector can be provided with at least one notch extending at least partially in the radial direction, and an axial spring of at least one contact tab can be inserted into the at least one notch, the axial spring can protrude from the notch at least by its bulge, and the bulge can be pressed back in the direction of the notch by a pressing surface of the mating connector.

[0030] In a connector assembly, particularly for high current plug-in connections, an embodiment having a connector as described above and at least one complementary mating connector coupled thereto allows an axial spring of at least one contact tab to be axially supported in the mating connector, in particular the axial spring can rest with its contact surface axially preloaded against a pressing surface of the mating connector.

[0031] The radial spring can preferably contact the mating connector in a radial direction. For example, the radial spring can be received in an opening of the mating connector and protrude from the opening substantially along a longitudinal axis in a direction opposite to the insertion direction. The radial spring can be supported by an inner wall of the opening and / or a frame of the opening. The radial spring can also be configured to contact the mating connector only when the spring force of the axial spring is reduced or too low.

[0032] The connector assembly can also comprise two mating connectors that can be coupled to the connector at different ends. In this case, the shielding spring shell can comprise at least one contact tab at both oppositely arranged ends, the axial spring of the at least one contact tab being axially supported in the respective mating connector. As a result, a constant shielding of the plug-in assembly that can withstand even strong vibrations can be ensured.

[0033] In the following, the invention will be described in more detail using embodiments with reference to the attached figures, in which elements that correspond to one another in terms of structure and / or function bear the same reference symbols.

[0034] The combination of features shown and described in each embodiment is for illustrative purposes only. According to the above description, a feature of an embodiment can be omitted if its technical effect is not important for a particular application. Conversely, according to the above description, an additional feature can be added to an embodiment if its technical effect is advantageous or necessary for a particular application.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0036] Firstly, an exemplary embodiment of a shielded spring shell 1 according to the invention shall be described in more detail with reference to FIGS.

[0037] The shield spring shell 1 comprises at least one contact tab 2 having two spring portions 6 adjacent to a fillet 4. One of the two spring portions 6 is configured as a radial spring 8 having elasticity at least in the radial direction, and the other of the two spring portions 6 is configured as an axial spring 10 having elasticity at least in the axial direction.

[0038] The shield spring shell 1 may comprise a shell body 12 extending along a longitudinal axis L. The shell body 12 may for example be a sheet metal 14 assembled to have an annular shape. The sheet metal 14 may be stamped in a stamping and bending process and assembled to have an annular shape. For this purpose, the sheet metal may be provided at its edge with interlocking teeth 16 pointing in the circumferential direction U, which establish a positive fit connection, in particular a dovetail connection, in the circumferential direction U.

[0039] In this exemplary embodiment, a plurality of contact tabs 2 are arranged in a coronal fashion at each end 18. The contact tabs 2 extend away from a respective edge 20 of the end 18, with adjacent contact tabs 2 being spaced apart from one another in the circumferential direction U such that slots 21 are formed between adjacently arranged contact tabs 2 in the circumferential direction U.

[0040] The arrangement of the contact tabs 2 at each end 18 is independent from the arrangement of the contact tabs 2 at the oppositely arranged end 18. The position, number and / or shape of the contact tabs 2 at each end may differ. In the figures of the present application, two embodiments of the contact tabs 2 according to the invention on the shield spring shell 1 are shown by way of example, which shall be described below as a first embodiment of the contact tab 3 and a second embodiment of the contact tab 5.

[0041] 1 and 2, the shell body can be provided with a reinforcing tab 22 protruding from one end along the longitudinal axis L in order to stabilize the connection area between the edges in the circumferential direction U. This reinforcing tab 22 can interrupt the arrangement of the contact tab 2 at one of the two ends 18. A further reinforcing tab 22 can be provided substantially diametrically opposite the first reinforcing tab in order to better stabilize the shell body in its cylindrical shape.

[0042] In this exemplary embodiment, the shield spring shell 1 facing away from the reinforcing tab 22 at its end 18 comprises contact tabs 3 according to the first embodiment extending away from the edge 20 substantially along the longitudinal axis L, at least before the shield spring shell 1 is inserted into a receptacle of a connector (see FIG. 1). As a result, the contact tabs 3 according to the first embodiment can be more easily pressed into the receptacle. These contact tabs 2 can be bent, for example, by a die after the shield spring shell 1 is inserted into the receptacle, thereby forming radial springs 8 and axial springs 10, as shown in FIG. 2.

[0043] To simplify bending of the contact tab 3, the contact tab 3 may extend at an angle inclined radially outwardly along the longitudinal axis L away from the edge 20 prior to bending. As a result, the opening 24 described by the shield spring shell 1 may widen conically in a direction towards the free end 26 of the contact tab 3.

[0044] At the free end 26 of the contact tab 3, which is formed by the axial spring 10 after bending, the contact tab 3 may have a bulge 28 which bulges radially inwards at least before bending. The bulge 28 may be formed with a contact surface 30 for contacting a pressing surface of a mating connector.

[0045] A first embodiment of a contact tab 3 is shown in Fig. 1 before bending and in Fig. 2 after bending. As can be seen especially in Fig. 1, the contact tab 3 according to the first embodiment can have a substantially uniform width in the circumferential direction U. Depending on the application and the type of the mating connector, the spring forces of the radial spring 8 and the axial spring 10 can be individually adapted by the shape of the contact tab and / or the preload of the respective springs in the radial or axial direction, respectively.

[0046] The contact tabs 3 according to the first embodiment can be preferably bent back radially outward by a first arc 32 in a direction towards the edge 20 from which the respective contact tab 3 extends away, and the radial spring 8 extends away from the first arc. The radial spring 8 can preferably extend away from the first arc 32 at an angle inclined radially outward from the longitudinal axis L, i.e. the radial spring 8 can be preloaded radially outward via the first arc 32.

[0047] At its end facing away from the first arc 32, the radial spring 8 joins with a second arc 34 by which a fillet 4 is formed and the axial spring 10 extends substantially radially away from the second arc 34. The fillet angle 36 between the radial spring 8 and the axial spring 10 may preferably be at most about 90°.

[0048] The axial spring 10 extends substantially radially away from the fillet 4 and, at least after bending, forms a contact surface 30 at a pronounced bulge 28 in a direction away from the oppositely disposed end 18.

[0049] The second embodiment of the contact tab 5 of Figures 1 and 2 is arranged at the end 18 with the reinforcing tab 22. In contrast to the first embodiment of the contact tab 3, this contact tab 5 according to the second embodiment does not have to be pressed into the receptacle of the connector. The contact tab 5 may therefore be bent at the end 18 with the reinforcing tab 22 before the shield spring shell 1 is inserted into the receptacle of the connector.

[0050] The contact tab 5 according to the second embodiment is bent back radially outward by a first circular arc 32 in a direction towards the end 18 from which the contact tab 5 extends away. In order to increase the spring stiffness of the contact tab 5, the contact tab 5 can be tapered in a circumferential direction U away from the edge 20. The contact tab 5 can be tapered up to the fillet 4, in particular at the spring section 6 forming the radial spring 8, and the axial spring 10 can extend substantially radially outward away from the fillet 4 with a uniform width in the circumferential direction U.

[0051] Compared to the first embodiment, the fillet angle 36 is sharper in the second embodiment, resulting in a greater preload of the axial spring 10 acting axially away from the opposite end 18 of the shell body 12.

[0052] Furthermore, in the second embodiment, the free end 26 of the axial spring 10 is further bent back in a direction towards the fillet 4, so that the contact surface 30 is formed in the third arc 38. Thus, according to the second embodiment, firstly, the relative movement between the connector and the mating connector in the axial direction can be compensated by the deflection around the third arc 38 and the deflection of the axial spring 10 around the second arc, i.e. the fillet.

[0053] Both embodiments of the contact tab 2 preferably comprise a radial spring 8 with a flexible contact surface 30 pointing in the radial direction and an axial spring 10 with a flexible contact surface 30 pointing in the axial direction, so that the relative movements of the mating connector and the connector in the axial and radial directions can be more reliably compensated.

[0054] The shield spring shell 1 can be preferably integrally formed as a unitary component 40, which allows the shield current to be conducted to the shield spring shell without additional contact resistance. The shield spring shell can be shaped, for example, as a stamped bent member, which allows for cheap and fast production, especially in large quantities.

[0055] An exemplary embodiment of the connector 42 will now be described in more detail below with reference to FIGS.

[0056] In FIG. 3 the first embodiment of the contact tab 3 is not yet bent, and in FIG. 4 the first embodiment of the contact tab 3 is shown bent.

[0057] The connector 42 comprises a base body 44 extending along a longitudinal axis L and a receptacle 46 into which the shield spring shell 1 is inserted. The receptacle 46 is open on both sides along the longitudinal axis L, so that the contact tab 3 according to the first embodiment can be pressed into the receptacle 46 before bending. The contact tab 2 of the oppositely arranged end 18 is therefore located on the oppositely arranged side of the receptacle 46 and preferably at least partially protrudes from the receptacle 46.

[0058] The contact tab 3 according to the first embodiment can be bent around the wall 48 of the receptacle 46 (see FIG. 4), whereby the wall 48 forms a support and facilitates forming a plurality of contact tabs 3 at the corresponding end 18, so that the plurality of contact tabs 3 have substantially the same structure. Thus, uniform contact of the corresponding mating connector can be achieved.

[0059] The connector 42 may include a radially projecting collar 50. The collar 50 divides the connector 42 into a first plug-in portion 52 for plugging into a first mating connector and a second plug-in portion 54 for plugging into a second mating connector. The plug-in portions 52, 54 may be adapted independently of one another to their respective complementary mating connector types.

[0060] The receptacle 46 may preferably be formed by a gap 56 between the base body 44 and the collar 50, whereby the inserted shield spring shell 1 may be positioned between the base body 44 and the collar 50. The shield spring shell 1 may preferably rest with at least its shell body 12 positioned on the exterior surface of the base body 44.

[0061] To fasten the collar 50 to the base body 44, ribs 58 may be provided and may extend from the base body 44 to the collar 50. Several ribs 58 may be spaced apart from one another in the circumferential direction U, whereby the ribs 58 partially subdivide the receptacle 46 into chambers 60 separated from one another in the circumferential direction U. A contact tab 3 of the first embodiment may be inserted into each chamber 60, the ribs 58 being disposed in the slots 21 between adjacent contact tabs 2.

[0062] For stabilization purposes, the collar 50 may include a shoulder 62 extending along the longitudinal axis L.

[0063] On the side facing the ribs, the shoulder extends between the ribs 58 in the circumferential direction U, thereby making it possible to stabilize the ribs 58 .

[0064] The shoulder 62 on the side facing the rib 58 forms the wall 48 around which the contact tab 3 of the first embodiment can be bent. The rib 58 preferably only partially projects into the receptacle so that the edge 20 facing the rib can hit the rib 58 and act as a stop for the shield spring shell to prevent the shield spring shell from being pressed deeper into the receptacle 46.

[0065] On the opposite side, the shoulder 62 may be provided with convex walls 64 spaced apart from one another in a circumferential direction U projecting along the longitudinal axis L, such that one respective contact tab 5 of the second embodiment is arranged in a window 66 between two adjacent convex walls 64. In particular, the fillet 4 of each contact tab 5 may be positioned in the window 66.

[0066] For the most inexpensive manufacture of connector 42, base body 44 and collar 50 can be integrally formed as a unitary housing 68. Preferably, unitary housing 68 can be electrically insulating. For example, housing 68 can be formed as an injection molded member from an insulating plastic material.

[0067] The flat surface 69 of the collar 50 facing the rib 58 may be provided with at least one radially extending notch. The notches may be arranged end-to-end in the circumferential direction U on the flat surface 69 or there may be several notches 70 separated from one another in the circumferential direction U.

[0068] The axial spring 10 of each contact tab 3 of the first embodiment can be inserted into the notch 70 so that the collar 50 can rest as flat as possible on the mating connector.

[0069] Figure 5 shows an exemplary embodiment of a connector assembly 72 having a connector 42 according to the present description, a first mating connector 74 coupled to the first plug-in part 52 and a second mating connector 76 coupled to the second plug-in part 54. Figure 6 shows a schematic detailed view of the contact areas between the connector 42 and the two mating connectors 74, 76.

[0070] The first mating connector 74 may be, for example, a switching device, in particular a printed circuit board, having an opening 78, and the first plug-in portion 52 of the connector 42 is positioned within the opening 78 up to a stop in the collar 50 on a surface of the first mating connector 74 substantially perpendicular to the longitudinal axis L.

[0071] 6, the radial spring 8 can establish radial contact with the inner wall of the opening 78 of the first mating connector 74, and the axial spring 10 can rest axially on the surface of the first mating connector 74. The at least one contact tab 3 can then contact the first mating connector with two pressing surfaces 80, which can further ensure the quality of the shielding.

[0072] The second mating connector 76 may be a shielded cable connector having a connector shield 82. The connector shield 82 comprises a receiving opening 84 into which the second plug-in part is at least partially inserted. At least the first arc 32 of at least one contact tab 5 is therefore arranged inside the connector shield 82. The contact tab 5 according to the second embodiment protrudes from the receiving opening 84 in a direction towards the collar 50, the radial spring 8 being radially preloaded towards a border 86 of the receiving opening 84. The axial spring 10 is arranged outside the receiving opening 84 and is axially preloaded on the surface of the connector shield 82.

[0073] The shielding spring shell 1 according to the invention allows compensation of movements between the mating connector and the connector in both radial and axial directions. The mating connector can be contacted at two points by the contact tabs, and the shielding is not compromised even when one of the contacts is released.

[0074] The contact tab 3 according to the first embodiment and the contact tab 5 according to the second embodiment can realize different tasks. The first mating connector 74 can be a holding frame to which the connector 42 is attached, for example by screwing or locking the connector 42 to the first mating connector 74. As a result, the relative movements between the connector 42 and the first mating connector 74 can be minimized. Since separating the connector 42 and the first mating connector 74 is not possible without further force, in particular by the screw connection, the contact tab 3 according to the first embodiment can contact the mating connector 74 both radially and axially. As a result, for every contact tab 3 of the first embodiment, two contacts to the mating connector can be established.

[0075] The second mating connector 76 can be, for example, a plug connector. Here, it is advantageous to have only the axial spring 10 in contact with the second mating connector 76 in the initial plug-in state. In the first case, the axial spring 10 can follow the relative movement, for example a vibration movement, of the second mating connector 76 towards the connector 42. Only when the spring force of the axial spring 10 is reduced or too low can the radial spring 8 radially contact the second mating connector 76. The radial spring 8 of the contact tab 5 of the second embodiment not only serves to compensate the relative movement between the second mating connector 76 and the connector 42 in the radial direction, but also serves as a lock in contact with the second mating connector 76 in extreme cases, thereby preventing damage to the shield due to a dropped contact.
