Description

Technical Field

[0001] The present invention relates to a shielded spring housing for high-current insertion connections, having at least one contact piece for contacting mating connectors. Background Technology

[0002] Shielding is crucial for ensuring the electromagnetic compatibility (EMC) of a system. Shielding is used to keep electric and / or magnetic fields away from the system or to protect the environment from magnetic fields emitted by the system. To ensure shielding in plug-in systems during operation, the shielding of the connector and the continuous contact with the mating connector are important, especially for shielding the mating connector. However, this has proven difficult due to the high stresses in use, such as vibration, which can cause contact disruption. Summary of the Invention

[0003] Therefore, the object of the present invention is to create a shielded spring shell that ensures continuous contact with the mating connector even under high stress, such as vibration.

[0004] According to the invention, this objective is achieved by the aforementioned shielding spring shell, wherein the contact piece comprises two spring portions adjacent to the rounded corner, and wherein one of the two spring portions is configured as a radially elastic radial spring, and the other of the two spring portions is configured as an axially elastic axial spring.

[0005] Using the solution according to the invention, at least one contact piece with its two spring portions can compensate for movement in the radial and axial directions between the connector and the mating connector, for example, due to vibrational stress. This ensures contact with the mating connector even when both radial and axial vibrational stresses occur simultaneously.

[0006] In the context of this application, "at least radially elastic" or "at least axially elastic" means that a radial spring can be primarily radially elastic, i.e., the spring strength of the radial spring can be the lowest in the radial direction, or an axial spring can be constructed to be primarily axially elastic, i.e., the spring strength of the axial spring is the lowest in the axial direction. Of course, a radial spring can also be axially elastic, or an axial spring can also be radially elastic; for example, due to static friction at the pressing surface arranged on the mating connector, the corresponding spring can elastically deflect in either the axial or radial direction, respectively.

[0007] Further developments are specified below, which can be combined independently of each other as needed, and are advantageous in themselves.

[0008] Axial springs may include yielding contact surfaces pointing in the axial direction, and / or radial springs may include yielding contact surfaces pointing in the radial direction. The corresponding compensation for relative movement between the connector and the mating connector in the axial and / or radial directions can be further optimized using yielding contact surfaces.

[0009] For example, at least one contact surface may be formed on the protruding portion of the contact piece. Preferably, at least the axial spring includes a portion that protrudes in the axial direction toward the pressing surface of the mating connector, so as to preload the axial spring in the direction toward the pressing surface of the mating connector, thereby ensuring high contact force.

[0010] The protruding portion of the protrusion can be an arc that protrudes in the direction toward the mating connector, particularly between two portions of the contact pieces arranged on a common straight line, or it can also be formed by bending the free end of the axial spring, particularly the axial spring, backward toward the rounded corner.

[0011] In order to obtain greater preload in the radial spring in the radial direction and in the axial spring in the axial direction, the angle of the fillet between the radial spring and the axial spring is at most about 90°, preferably between about 45° and about 90°.

[0012] The shielding spring housing may include a housing body extending along a longitudinal axis, wherein at least one contact piece extends away along the longitudinal axis at at least one end of the housing body. The at least one contact piece may extend substantially along the longitudinal axis at least before being inserted into the connector, thereby facilitating the pushing of the contact piece through the connector's receptacle.

[0013] Alternatively or additionally, at least one contact piece may be bent rearward, particularly radially outward from the edge at the end of the housing body along the longitudinal axis. The radial spring can then be arranged substantially along a longitudinal axis parallel to the sheath surface of the housing body and can be radially deflected toward or away from the housing body. Thus, the housing body can also serve 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 spring plates extending in the direction toward the sheath surface of the housing body and supported on the sheath surface. As a result, the radial spring is not only defined in the radial direction by the arc between the radial spring and the edge of the housing body, but also improved by the spring plates.

[0015] In this configuration, the contact piece can be bent radially outward at the end of the radial spring away from the edge, thereby forming a rounded corner from which the axial spring extends substantially radially outward.

[0016] According to another advantageous embodiment, the shielding spring housing can be configured to contact two different mating connectors. For this purpose, the shielding spring housing can have at least one contact piece at each of its respective ends, which are positioned opposite each other along its longitudinal axis.

[0017] The contact tabs at opposite ends can be structurally identical to those at the corresponding other end. However, at least before the shielding spring housing is inserted into the connector's receptacle, the contact tabs may extend substantially along the longitudinal axis away from the corresponding edge at at least one end to facilitate insertion of the contact tabs through the receptacle. At the other end, at least one contact tab may be bent backward before being inserted into the connector's receptacle. As a result, each contact tab may protrude from the opposite ends of the connector's receptacle and each contact the mating connector.

[0018] To optimize the contact between the shielding spring housing and the mating connector, a plurality of contact tabs can be arranged in a crown-like manner at at least one end, particularly at both ends, along the longitudinal axis of the housing body. The contact tabs can be spaced apart from each other in the circumferential direction, thereby forming a slot between adjacent contact tabs in the circumferential direction. Each contact tab can then be deflected independently of its adjacent contact tabs.

[0019] If multiple contact pieces are arranged at both ends of the shielding spring housing, the arrangement and / or number of contact pieces at one end can be independent of the arrangement and / or number of contact pieces at the other end. Therefore, the contact pieces at the respective ends of the complementary mating connector can be optimized.

[0020] The shielding spring housing can preferably be integrally formed as a single component, thereby allowing shielding current to be conducted through the shielding spring housing without additional contact resistance. The shielding spring housing can, for example, be formed as a stamped and bent component, enabling inexpensive and rapid production, particularly for mass production. For example, a sheet of metal can be stamped and rolled up to form the housing body. The shape of the shielding spring housing can be fixed circumferentially between opposing edges of the sheet of metal using form-fitting, particularly dovetail, connections. For example, the opposing edges can be provided with interlocking teeth to create the form-fitting.

[0021] A connector for coupling to at least one mating connector may include a base extending along a longitudinal axis, wherein the connector is provided with a housing into which a shielding spring shell according to one of the foregoing embodiments is inserted, and wherein at least one contact piece protrudes from the housing, particularly along the longitudinal axis.

[0022] For example, a connector can be an adapter element that electrically connects two mating connectors to each other. For example, a connector can be a connector interface that can be inserted into an opening in a component to be actuated (such as a printed circuit board) and establish contact with that component.

[0023] At least one contact piece may be bent rearward around the wall of the receiver at at least one end of the shielding spring housing. Specifically, in this case, at least one contact piece may be bent radially outward and rearward around the wall of the receiver only after the shielding spring housing has been inserted into the receiver. As a result, at least one contact piece, particularly the radial spring of at least one contact piece, can be supported against the wall. An axial spring may extend radially outward from the wall as a free end of the contact piece.

[0024] The connector may include a radially projecting collar to separate a front insertion portion for inserting into a first mating connector and a rear insertion portion for inserting into a second mating connector. For example, the collar may project radially beyond the opening of the mating connector, thereby preventing the connector from being inserted further into the opening.

[0025] The housing is preferably formed in the radial direction by a gap between the base and the collar, thereby retaining the inserted shielding spring shell between the base and the collar. The shielding spring shell, the base, and the collar can have substantially rotationally symmetric shapes, such as cylindrical shapes. The shielding spring shell can be coaxially wound around the sheath surface of the base.

[0026] To ensure connectors can be produced as quickly and cheaply as possible, the ferrule can be molded onto the base. The ferrule and base can be integrally formed into a single housing portion, for example, by injection molding. The housing portion can preferably be formed of an electrically insulating material, particularly a plastic material, thereby preventing electric shock due to accidental contact with the housing portion. Depending on the application, the housing portion may also be formed of a metallic material.

[0027] The connector may be provided with ribs extending from the base to the collar and retaining the collar on the base. Multiple ribs may be circumferentially separated from each other, thus subdividing at least a portion of the housing into chambers circumferentially separated from each other. Each chamber may be penetrated at one end of the shielding spring housing by a corresponding contact piece among a plurality of contact pieces. Therefore, the corresponding contact pieces may be circumferentially separated from each other, and jamming of the contact pieces may be prevented, for example, by deflecting them circumferentially.

[0028] Because multiple contact pieces can be spaced apart from each other in the circumferential direction, slots are formed between the contact pieces, into which ribs can be inserted. The ribs can be used not only to attach the collar to the base or to separate the contact pieces in the circumferential direction, but also as stops to lock the insertion movement of the shielding spring housing into the receiver, as the protrusion of the shielding spring housing strikes the rib along the longitudinal axis from the edge extending away from at least one contact piece of a chamber.

[0029] If the collar is placed as flat and stable as possible on the mating connector, the collar may have at least one notch extending in the radial direction on its flat side facing the mating connector, into which at least one axial spring of a contact piece may be at least partially inserted. The axial spring may protrude from the notch at least through its protruding portion, wherein the latter may be pushed backward along the direction of the notch by the pressing surface of the mating connector.

[0030] In connector assemblies, particularly for high-current insertion connections, in embodiments of the aforementioned connector and at least one complementary mating connector coupled to it, an axial spring of at least one contact piece can be supported on the mating connector in the axial direction. Specifically, the axial spring can preload its contact surface in the axial direction against the pressing surface of the mating connector.

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

[0032] The connector assembly may also include two mating connectors that can be attached to the connector at different ends. In this case, the shielding spring housing may have at least one contact piece at each of the two opposite ends, with its axial spring supported in the axial direction on the respective mating connector. As a result, constant shielding of the insertion assembly can be ensured, which resists even strong vibrations.

[0033] In the following description, the invention will be illustrated with reference to the accompanying drawings and embodiments. Elements corresponding to each other in terms of structure and / or function in the drawings are given the same reference numerals.

[0041] First, refer to Figure 1 and 2 An exemplary embodiment of the shielding spring housing 1 according to the present invention will be described in more detail below.

[0042] The shielding spring housing 1 includes at least one contact piece 2 having two spring portions 6 adjacent to a fillet 4, wherein one of the two spring portions 6 is configured as a radially elastic radial spring 8, and the other of the two spring portions 6 is configured as an axially elastic axial spring 10.

[0043] The shielding spring housing 1 may include a housing body 12 extending along a longitudinal axis L. The housing body 12 may be, for example, a metal sheet 14 assembled into a ring. The metal sheet 14 may be stamped out during stamping and bending, and then assembled into a ring. For this purpose, the metal sheet may include interlocking teeth 16 on its end edge pointing in the circumferential direction U, wherein the teeth 16 establish a form-fit connection in the circumferential direction U, particularly a dovetail connection.

[0044] In this exemplary embodiment, a plurality of contact pieces 2 are arranged in a crown-like manner at corresponding ends 18, wherein the contact pieces 2 extend away from the corresponding edge 20 of the end 18, and adjacent contact pieces 2 are spaced apart from each other in the circumferential direction U, thereby forming a slot 21 between the contact pieces 2 arranged adjacent to each other in the circumferential direction U.

[0045] Contact pieces 2 are arranged at corresponding ends 18 independently of contact pieces 2 arranged at opposite ends 18. The position, number, and / or shape of contact pieces 2 at corresponding ends may differ. In the accompanying drawings, two embodiments of contact pieces 2 according to the invention on the shielding spring housing 1 are shown by way of example, which are described below as a first embodiment of contact piece 3 and a second embodiment of contact piece 5.

[0046] like Figure 1 and 2 As shown in the example, the shell body may be provided with a reinforcing piece 22 protruding from one end along the longitudinal axis L to stabilize the connection area between the edges in the circumferential direction U. This reinforcing piece 22 may interrupt the contact piece 2 arranged at one of the two ends 18. To better stabilize the shell body in its cylindrical shape, another reinforcing piece 22 may be provided substantially diametrically toward the first reinforcing piece.

[0047] In this exemplary embodiment, the shielding spring housing 1 has a contact piece 3 at its end 18 opposite to the reinforcing piece 22, the contact piece 3 extending substantially along the longitudinal axis L away from the edge 20 at least before the shielding spring housing 1 is inserted into the connector's receptacle (see...). Figure 1 As a result, the contact pieces 3 according to the first embodiment can be pushed more easily through the receiver. After the shielding spring housing 1 is inserted into the receiver, these contact pieces 2 can be bent, for example, by a die, thereby forming a radial spring 8 and an axial spring 10, as shown. Figure 2 As shown.

[0048] To simplify the bending of the contact piece 3, before bending, the contact piece 3 can extend away from the edge 20 at a radially outward angle along the longitudinal axis L. As a result, the opening 24 described by the shielding spring housing 1 can be tapered in the direction toward the free end 26 of the contact piece 3.

[0049] At the free end 26 of the contact piece 3 formed by the axial spring 10 after bending, the contact piece 3 may have a protrusion 28 that convexes radially inward at least before bending. A contact surface 30 may be formed on the protrusion 28 for contacting the pressing surface of the mating connector.

[0050] The first embodiment of contact piece 3 before bending Figure 1 As shown in the diagram and after bending Figure 2 As shown in the image. (See also: [image source]). Figure 1 As can be seen, the contact piece 3 according to the first embodiment can have a substantially uniform width in the circumferential direction U. Depending on the application and type of the mating connector, the spring forces of the radial spring 8 and the axial spring 10 can be adjusted individually by the shape of the contact piece and / or the preload of the corresponding spring in the radial or axial direction.

[0051] According to the first embodiment, the contact piece 3 is preferably bent radially outward and backward in the direction toward the edge 20, and the corresponding contact piece 3 extends away from the edge away from the first arc 32, wherein the radial spring 8 extends away from the first arc. The radial spring 8 is preferably extended away from the first arc 32 at an angle inclined radially outward from the longitudinal axis L, that is, the radial spring 8 can be preloaded radially outward on the first arc 32.

[0052] The radial spring 8 flows into the second arc 34 at its end away from the first arc 32, forming a fillet 4 through the second arc, and the axial spring base extends radially away from the second arc. The angle 36 of the fillet between the radial spring 8 and the axial spring 10 is preferably up to about 90°.

[0053] The axial spring 10 extends substantially in the radial direction away from the fillet 4, wherein at least after bending, a contact surface 30 is formed on the protrusion 28, which protrudes in a direction away from the oppositely disposed end 18.

[0054] Figure 1 and 2 In the second embodiment, the contact piece 5 is arranged at the end 18 with the reinforcing piece 22. Unlike the first embodiment of the contact piece 3, the contact piece 5 according to the second embodiment does not need to be pushed past the connector's housing. Therefore, the contact piece 5 can be bent at the end 18 with the reinforcing piece 22 before the shielding spring shell 1 has been inserted into the connector's housing.

[0055] According to the second embodiment, the contact piece 5 is bent radially outward and rearward in a direction toward the end 18 extending away from the contact piece 5 via a first arc 32. To increase the spring stiffness of the contact piece 5, the contact piece 5 may gradually taper in the circumferential direction U in a direction away from the edge 20. The contact piece 5 may gradually taper to a rounded corner 4, particularly in the spring portion 6 forming the radial spring 8, and the axial spring 10 may extend substantially radially outward away from the rounded corner 4 in the circumferential direction U with a uniform width.

[0056] Compared to the first embodiment, the angle 36 of the rounded corner is sharper in the second embodiment, which results in a greater preload of the axial spring 10 in the axial direction at the opposite end 18 away from the housing body 12.

[0057] Furthermore, in the second embodiment, the free end 26 of the axial spring 10 is further bent rearward in the direction toward the fillet 6, resulting in the contact surface 30 being formed on the third arc 38. According to the second embodiment, the relative movement between the connector and the mating connector in the axial direction can therefore be compensated first by deflection around the third arc 38 and by deflection of the axial spring 10 around the second arc, i.e., the fillet.

[0058] Two preferred embodiments of the contact piece 2 include: a radial spring 8 having a yielding contact surface 30 pointing radially; and an axial spring 10 having a yielding contact surface 30 pointing axially. As a result, relative movement between the mating connector and the connector in the axial and radial directions can be compensated more reliably.

[0059] The shielding spring housing 1 can preferably be integrally formed as a single component 40, whereby the shielding current can be conducted through the shielding spring housing without additional contact resistance. The shielding spring housing can be formed, for example, as a stamped and bent component, which enables inexpensive and rapid production, especially for mass production.

[0060] Now refer to the following Figure 3 and 4 An exemplary embodiment of connector 42 will be described in more detail below.

[0061] exist Figure 3 In the first embodiment of contact piece 3, it is not yet bent, while... Figure 4 In the first embodiment, the contact piece 3 is shown as curved.

[0062] The connector 42 includes a base 44 extending along the longitudinal axis L and a housing 46 into which a shielding spring shell 1 is inserted. The housing 46 is open on both sides along the longitudinal axis L, such that the contact piece 3 according to the first embodiment can be pushed over the housing 46 and then bent. Thus, the contact pieces 2 at opposite ends 18 are arranged on opposite sides of the housing 46 and preferably at least partially protrude from the housing 46.

[0063] According to the first embodiment, the contact piece 3 can be bent around the wall 48 of the receiver 46 (see...). Figure 4 The wall 48 provides support and facilitates the formation of multiple contact pieces 3 at the respective ends 18, such that the multiple contact pieces 3 have substantially the same structure. Therefore, uniform contact of the corresponding mating connectors can be achieved.

[0064] Connector 44 may include a radially projecting collar 50 that divides connector 44 into a first insertion portion 52 for insertion into a first mating connector and a second insertion portion 54 for insertion into a second mating connector. Insertion portions 52 and 54 may be independently adapted to the type of corresponding complementary mating connectors.

[0065] The housing 46 can preferably be formed by a gap 56 between the base 44 and the collar 55, through which the shielding spring housing 1 can be arranged between the base 44 and the collar 50. The shielding spring housing 1 can preferably be placed on the sheath surface of the base 44, at least with its housing body 12.

[0066] To secure the collar 50 to the base 44, ribs 58 may be provided, extending from the base 44 to the collar 50. Multiple ribs 58 may be spaced apart from each other in the circumferential direction U, thereby partially subdividing the receptacle 46 into chambers 60 separated from each other in the circumferential direction U. Contact pieces 3 of the first embodiment may be inserted through each chamber 60, with the ribs 58 arranged in slots 21 between adjacent contact pieces 2.

[0067] For stability, the collar 50 may be provided with a shoulder 62 extending along the longitudinal axis L.

[0068] On the side facing the ribs, the shoulder can extend in a circumferential direction U between the ribs 58, thereby stabilizing the ribs 58.

[0069] A shoulder 62 on the side facing the rib 58 forms a wall 48, around which the contact piece 3 of the first embodiment can be bent. The ribs 58 preferably extend only partially into the receiver, so that they can serve as stops for the shielding spring housing, since the edge 20 facing the rib impacts the rib 58 and prevents the shielding spring housing from being pushed deeper into the receiver 46.

[0070] On the opposite side, the shoulder 62 may include merlons 64 protruding along the longitudinal axis L and spaced apart from each other in the circumferential direction U, such that a corresponding contact piece 5 of the second embodiment is arranged in a window 66 between two adjacent merlons 64. In particular, the fillet 4 of each contact piece 5 may be located in the window 66.

[0071] To produce connector 42 at the lowest possible cost, the base 44 and collar 50 can be integrally formed into a one-piece housing 68. Preferably, the one-piece housing 68 can be electrically insulated. For example, housing 68 can be formed from an insulating plastic material as an injection-molded component.

[0072] At least one notch extending in the radial direction may be provided on the flat side 69 of the collar 50 facing the rib 58. The notch may be arranged end-to-end on the flat side 69 in the circumferential direction U, or a plurality of notches 70 may be provided to be separated from each other in the circumferential direction U.

[0073] In the first embodiment, the axial spring 10 of each contact piece 3 can be inserted into the recess 70 so that the collar 50 can be placed as flat as possible on the mating connector.

[0074] Figure 5 An exemplary embodiment of the connector assembly 72 is shown, which has a connector 42 as described above, a first mating connector 74 connected to a first insertion portion 52, and a second mating connector 76 connected to a second insertion portion 54. Figure 6 A schematic detailed view of the contact area between connector 42 and the two mating connectors 74, 76 is shown.

[0075] The first mating connector 74 may be, for example, a switching device, particularly a printed circuit board, having an opening 78, into which the first insertion portion 52 of the connector 42 is arranged until a stop of the collar 50 on the surface of the first mating connector 74, substantially perpendicular to the longitudinal axis L.

[0076] like Figure 6As shown, 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 be axially positioned on the surface of the first mating connector 74. At least one contact piece 3 can then contact the first mating connector on the two pressing surfaces 80, thereby further ensuring the quality of shielding.

[0077] The second mating connector 76 may be a shielded cable connector having a connector shield 82 including a receiving opening 84 into which a second insertion portion is at least partially inserted, such that at least a first arc 32 of at least one contact piece 5 is arranged inside the connector shield 82. According to the second embodiment therein, the contact piece 5 extends from the receiving opening 84 in a direction toward the collar 50, wherein a radial spring 8 is preloaded in a radial direction toward the boundary 86 of the receiving opening 84. An axial spring 10 is arranged outside the receiving opening 84 and is supported axially in a preloaded manner on the surface of the connector shield 82.

[0078] Movement between the mating connectors can be compensated in both the radial and axial directions by means of the shielding spring housing 1 according to the invention. The mating connectors can make contact at two points via contact tabs, wherein even if one contact disengages, the shielding will not be damaged.

[0079] The contact pieces of the first and second embodiments 3 and 5 can perform different tasks. The first mating connector 74 can represent a retaining frame, on which the connector 42 is mounted, for example, by screwing or locking the connector 42 onto the first mating connector 74. As a result, relative movement between the connector 42 and the first mating connector 74 can be minimized. Since the connector 42 and the first mating connector 74 can only be separated by increased force, particularly by a threaded connection, the contact piece 3 according to the first embodiment can contact the mating connector 74 radially and axially. As a result, two contacts can be established for each contact piece 3 of the first embodiment to the mating connector.

[0080] The second mating connector 76 can be, for example, a plug connector. Advantageously, only the axial spring 10 contacts the second mating connector 76 in the initial state of insertion. In a first example, the axial spring 10 can follow the relative movement of the second mating connector 76 toward the connector 42, such as vibratory movement. The radial spring 8 can only contact the second mating connector 76 in the radial direction when the spring force of the axial spring 10 decreases or becomes too low. In the second embodiment, the radial spring 8 of the contact piece 5 not only compensates for the relative movement between the second mating connector 76 and the connector 42 in the radial direction, but also, in extreme cases, acts as a lock for contact with the second mating connector 76, thereby preventing poor shielding due to contact failure.
