Abstract

The first ferrite core (100a, 200a, 300a, 400a, 500a, 600a) is configured to be arranged on the second ferrite core (100b, 200b, 300b, 400b, 500b, 600b) according to the mounting direction (2), so that the first interlocking surface (102a, 202a, 302a, 402a, 502a, 602a) faces the second interlocking surface (102b, 202b, 302b, 402b, 502b, 602b). The interlocking surfaces (102, 202, 302, 402, 502, 602) provide contact such that the first ferrite core (100a, 200a, 300a, 400a, 500a, 600a) contacts the second ferrite core (100b, 200b, 300b, 400b, 500b, 600b) along the transverse direction (3), and the transverse direction (3) is perpendicular to the mounting direction (2).

Description

Technology Field

[0001] The present invention relates to a ferrite core assembly for a pyrotechnic connector that is plugged into an electrical connector, particularly a mating connector of a safety restraint system. Background Technology

[0002] Ferrite cores are components made of ferrite material and are typically used for their magnetic properties and high electrical resistance. They are particularly effective in suppressing high-frequency noise and electromagnetic interference (EMI).

[0003] Ferrite cores are commonly used in electrical connectors, such as pyrotechnic connectors (also known as squid connectors), to suppress high-frequency noise and electromagnetic interference (EMI) in order to preserve the integrity of signal transmission.

[0004] From the prior art, for example from US2003162444A1 and US2002009924A1, it is known to use split ferrite cores composed of two halves surrounding a cable. To maintain the effective function of the split ferrite core, however, it is important to prevent relative movement between its halves. Lateral or misaligned displacement can create gaps in the magnetic path, thereby reducing the efficiency of the ferrite in attenuating EMI. In US2003162444A1, prevention of lateral movement between the halves is achieved through latch arms and holding arms of an insulating housing that hold the ferrite members in place. In US2002009924A1, the ferrite component is held within the housing by retaining clips on the housing wall that engage with locking ledges on the ferrite component. Furthermore, a deflectable protrusion applies a retentive force to hold the ferrite component against the retaining clips.

[0005] However, these solutions require features that accommodate specific and complex characteristics. It would be desirable to provide a simplified and effective solution to prevent the relative movement of ferrite halves along at least one direction.

[0006] The object of the present invention is achieved by a ferrite core assembly for a pyrotechnic connector that is plugged into an electrical connector, particularly a mating connector of a safety restraint system. The ferrite core assembly comprises: a first ferrite core having a first engagement surface and a second ferrite core having a second engagement surface, wherein the first ferrite core is configured to be arranged on the second ferrite core according to the mounting direction such that the first engagement surface faces the second engagement surface, and at least one channel for receiving a terminal or wire is defined between the first engagement surface and the second engagement surface along the extension direction, the extension direction is perpendicular to the mounting direction, and the first engagement surface and the second engagement surface provide contact of the first ferrite core with the second ferrite core along the transverse direction, and the transverse direction is perpendicular to the mounting direction and the extension direction, respectively.

[0007] The contact of the first ferrite core with respect to the second ferrite core along the transverse direction prevents unwanted relative displacement between the two ferrite cores. This prevents the creation of gaps in the magnetic path that may be caused by the movement of the ferrite cores. The movement-blocking function in at least one direction is achieved by the features of the ferrite core assembly itself, in particular the first and second interlocking surfaces, without requiring additional blocking means provided by the housing of the electrical connector in which the ferrite core assembly can be accommodated. This provides a simplified and effective solution for preventing relative movement of the two ferrite cores along at least one direction.

[0008] As used herein, the terms “first” and “second” in relation to ferrite cores are used to distinguish two ferrite cores of a ferrite core assembly and may not imply a specific order, sequence, or hierarchy.

[0009] According to one embodiment, the first engagement surface and the second engagement surface may provide mutual contact between the first ferrite core and the second ferrite core in opposite directions along the transverse direction.

[0010] The mutual contact between the first interlocking surface and the second interlocking surface prevents displacement and misalignment of the first and second ferrite cores in opposing directions along the transverse direction. This further fixes the position of the first ferrite core relative to the second ferrite core.

[0011] According to one embodiment, the ferrite core assembly may be characterized in that the mutual displacement of the first and second ferrite cores in both opposing directions along the transverse direction is exclusively locked by the ferrite core assembly without the use of additional latching means, locking means, or housing features separate from the ferrite core assembly.

[0012] According to one embodiment, the ferrite core assembly may have a rectangular or cuboidal shape. The ferrite core assembly may have chamfered or rounded edges. In the context of this description, the first ferrite core defines half ferrite of the ferrite core assembly. The second ferrite core defines another half ferrite of the ferrite core assembly. Each of the first ferrite core and the second ferrite core may be machined from a ferrite block. According to one embodiment, the first ferrite core and the second ferrite core may have the same shape. This simplifies production and facilitates logistics for assembly, as only one shape is required. Alternatively, the first ferrite core may have a shape that is complementary and different from the shape of the second ferrite core. This configuration facilitates specific mutual contact, thereby improving the prevention of lateral movement between the two ferrite cores.

[0013] According to one embodiment, at least one of the first ferrite core and the second ferrite core may be provided with at least one locking ridge that protrudes perpendicularly from its engaging surface and extends longitudinally along the extension direction. Thus, the ferrite core is provided with a locking ridge capable of engaging with a corresponding feature to limit relative movement between the two ferrite cores, particularly along the transverse direction, without the need for additional means of blocking from the housing of the electrical connector in which the ferrite core assembly may be housed. In one embodiment, the at least one locking ridge may extend longitudinally along the extension direction from the front face of the ferrite core assembly to the back face of the ferrite core assembly. Alternatively, the at least one locking ridge may extend only partially from the front face of the ferrite core assembly, from the back face, toward the back face of the ferrite core assembly, and toward the front face, respectively.

[0014] According to one embodiment, at least one locking ridge of the first ferrite core may come into contact with at least one locking ridge of the second ferrite core along the transverse direction. Such contact between the two locking ridges may create more surface contact between the first and second ferrite cores. This may enable further restriction of movement along the transverse direction.

[0015] Guiding features may be provided on the first engagement surface and the second engagement surface, respectively. The guiding features may be configured to facilitate the alignment of the first ferrite core with respect to the second ferrite core during the assembly of the ferrite core assembly. According to one embodiment, at least one locking ridge may include a side wall parallel to the side of the first ferrite core or the second ferrite core, and the side is defined in a plane formed by the extension direction and the mounting direction. By providing a side wall of the locking ridge parallel to the side of the ferrite core, a surface perpendicular to the transverse direction is created. This can improve the ability to restrict movement along the transverse direction. Furthermore, this parallel configuration can facilitate the positioning of the first ferrite core with respect to the second ferrite core by the locking ridge.

[0016] According to one embodiment, at least one of the first ferrite core and the second ferrite core may be provided with at least one locking recess that deepens perpendicularly from the respective engagement surface of the ferrite core and extends longitudinally along the extension direction. The locking recess provides a defined cavity or groove for engagement with a corresponding feature, while restricting relative movement, particularly along the lateral direction, without the need for additional means of blocking from the housing of the electrical connector in which the ferrite core assembly may be accommodated. In one embodiment, the at least one locking recess may extend longitudinally along the extension direction from the front of the ferrite core assembly to the rear of the ferrite core assembly. Alternatively, the at least one locking recess may extend only partially from the front of the ferrite core assembly, from the rear, toward the rear of the ferrite core assembly, and toward the front, respectively.

[0017] According to one embodiment, at least one locking ridge of each second ferrite core of the first ferrite core may be at least partially received and mutually locked in at least one locking recess of each first ferrite core of the second ferrite core. The mutual locking engagement of the locking ridges within the locking recess forms a shape-fit connection, preventing relative movement between the first and second ferrite cores in both opposing directions along the transverse direction. This shape-fit connection improves the stability and alignment of the ferrite core assembly. In particular, this achieves these effects without relying on additional blocking features distinct from the ferrite core assembly.

[0018] According to one embodiment, at least one channel may have an oblong or circular cross-section in a plane formed by the mounting direction and the transverse direction. Thus, at least one channel is suitable for accommodating a cable or wire. Alternatively, at least one channel may have a rectangular cross-section in a plane formed by the mounting direction and the transverse direction. In particular, at least one channel may be dimensioned to accommodate an electrical terminal rather than a cable. Since the cross-section of the electrical terminal is smaller than the cross-section of the cable, a ferrite core assembly having a rectangular channel for the electrical terminal is more compact than a ferrite core assembly designed to accommodate cables.

[0019] The longest dimension of the rectangular channel measured in a plane defined by the mounting direction and the transverse direction may be parallel to the protruding direction of the locking ridge. This configuration can provide a more compact ferrite core assembly than a configuration in which the longest dimension of the rectangular channel measured in a plane defined by the mounting direction and the transverse direction is perpendicular to the protruding direction of the locking ridge.

[0020] According to one embodiment, the ferrite core assembly may include two distinct channels. Thus, each channel is configured to accommodate an individual electrical terminal or cable. This arrangement enables the separation and alignment of electrical terminals or cables within the ferrite core assembly. Each opening of the channels on the front and / or rear of the ferrite core assembly may be chamfered inward toward the interior of each channel. This can reduce the risk of damaging electrical terminals or wires during assembly.

[0021] According to one embodiment, at least one of the first ferrite core and the second ferrite core may include a recess extending along the extension direction, and at least one channel may be partially formed by the recess. The recess may be dimensioned to accommodate an electrical terminal or a cable. According to one embodiment, the recess configured to accommodate an electrical terminal or a cable may correspond to a locking recess of one of the ferrite cores. According to another embodiment, the first ferrite core may include a recess or groove extending along the extension direction. The second ferrite core may include a corresponding recess or groove extending along the extension direction. The channel may be formed by a recess or groove of the first ferrite core facing the corresponding recess or groove of the second ferrite core.

[0022] According to one embodiment, at least one channel may be formed between at least one locking ridge of the first ferrite core and the second engagement surface of the second ferrite core and the first engagement surface of the first ferrite core. In particular, at least one channel may be formed between the locking ridge of the first ferrite core and the recess of the second ferrite core and the recess of the first ferrite core. This configuration provides a more compact solution because the locking ridge functions simultaneously as a form-fit connection to prevent mutual displacement of the ferrite cores and as a channel to accommodate electrical terminals or cables. At least one channel may be at least partially defined by the sidewall of the locking ridge of one of the ferrite cores. At least one channel may be at least partially defined between the sidewall of the locking ridge of the first ferrite core and the sidewall of the locking ridge of the second ferrite core. At least one channel may be at least partially defined between the two sidewalls of the locking recess of one of the ferrite cores.

[0023] According to one embodiment, the first engagement surface and the second engagement surface may be further configured to provide contact of the first ferrite core with respect to the second ferrite core along the extension direction. Contact along the extension direction provides additional stability to the ferrite core assembly by limiting the relative movement of the first and second ferrite cores in two directions, namely the transverse direction and the extension direction. Contact of the first ferrite core with respect to the second ferrite core along the extension direction may be achieved by contact of the locking ridge of the first ferrite core with respect to the corresponding locking ridge of the second ferrite core along the extension direction, or with respect to the corresponding locking recess.

[0024] The number of locking ridges and / or locking recesses in a ferrite core assembly is not limited.

[0025] The object of the present invention is also achieved by a pyrotechnic connector that plugs into an electrical connector, in particular a mating connector along a mounting direction, in particular a mating connector of a safety restraint system. The electrical connector comprises: a connector housing for receiving an electrical terminal or wire, and a ferrite core assembly, wherein the ferrite core assembly is received in the connector housing, and the ferrite core assembly comprises at least one channel for receiving an electrical terminal or wire along an extension direction, the extension direction being perpendicular to the mounting direction, and the ferrite core assembly comprises a first ferrite core having a first engagement surface and a second ferrite core having a second engagement surface, wherein the first ferrite core is configured to be arranged on the second ferrite core along the mounting direction such that the first engagement surface faces the second engagement surface, and the first engagement surface and the second engagement surface are configured to provide contact of the first ferrite core with the second ferrite core along the transverse direction, the transverse direction being perpendicular to the mounting direction and the extension direction, respectively.

[0026] The electrical connector may be characterized by the absence of a latching means within the connector housing for holding a first ferrite core to a second ferrite core. This enables simplification of the design of the connector housing. The electrical connector may include a receptacle for receiving a wire fixture.

[0027] The object of the present invention can be further achieved by an assembly method for assembling a ferrite core assembly into an electrical connector. The assembly method may include the steps of inserting a first ferrite core into a connector housing along a mounting direction, introducing at least one electrical terminal or wire into a corresponding channel of the first ferrite core along a mounting direction, and inserting a second ferrite core along a mounting direction to arrange a second ferrite core on the first ferrite core. This assembly method enables the assembly of different components in a single direction, namely the mounting direction, thereby enabling a vertical assembly process. This vertical sequence facilitates the assembly process. Brief explanation of the drawing

[0029] As used below, reference symbols ending in the Latin letter "A" (e.g., 100A or 102A) refer to the first ferrite core, while reference symbols ending in the Latin letter "B" (e.g., 100B, 102B) refer to the second ferrite core of the ferrite core assembly. Specific details for implementing the invention First embodiment

[0030] FIG. 1 illustrates a ferrite core assembly (10) according to a first embodiment. The ferrite core assembly (10) has the shape of a rectangular prism. The ferrite core assembly (10) includes a front surface (12) facing a rear surface (14) along an extension direction (1). The extension direction (1) is indicated by an arrow (1) and is parallel to the Z-axis of the orthogonal coordinate system illustrated in FIG. 1. The front surface (12) and the rear surface (14) each have a rectangular shape. The front surface (12) and the rear surface (14) are connected by four side walls (16, 18, 20, 22). Two side surfaces (16, 20) face each other along the Y-axis of the orthogonal coordinate system illustrated in FIG. 1. Two side surfaces (18, 22) face each other along the X-axis of the orthogonal coordinate system illustrated in FIG. 1. The sides (16, 18, 20, 22) are each joined by chamfered edges (24) at their intersections.

[0031] The ferrite core assembly (10) includes two distinct channels (26, 28). Each channel (26, 28) is configured to accommodate one electrical terminal (not shown) along the extension direction (1). The two channels (26, 28) have the same dimensions and shapes. Each channel (26, 28) extends from the front (12) to the rear (14) of the ferrite core assembly (10).

[0032] In the first embodiment, each channel (26, 28) has a hollow rectangular cross-section having two parallel lengths (30) and two parallel widths (32) in a plane parallel to the front surface (12). The parallel lengths (30) are each larger than the parallel widths (32). The lengths (30) are parallel to the X-axis of the orthogonal coordinate system shown in FIG. 1, while the widths (32) are parallel to the Y-axis of the system.

[0033] In a first embodiment, the channels (26, 28) are positioned such that the parallel lengths (30) of the rectangular cross-section of channel (26) are aligned with the corresponding parallel lengths (30) of the rectangular cross-section of channel (28). Each of the channels (26, 28) is dimensioned to accommodate an electrical terminal. In particular, the channels (26, 28) are configured to accommodate an electrical terminal of a rectangular cross-section.

[0034] On the front (12), each channel (26, 28) on the rear (14) is chamfered inward toward the rear (14) and each channel (26, 28) on the front (12). This prevents sharp edges that could scratch or damage the electrical terminal while inserting the electrical terminal into the ferrite core assembly.

[0035] According to the present invention, a ferrite core assembly (10) includes a first ferrite core (100A) and a second ferrite core (100B).

[0036] In the first embodiment, the first ferrite core (100A) and the second ferrite core (100B) have the same shape. Since the two ferrite cores (100A, 100B) are identical, only one ferrite core (100B) is depicted in FIG. 2. The description of the second ferrite core (100B) shown in FIG. 2 applies equally to the first ferrite core (100A).

[0037] The first ferrite core (100A) includes a first engagement surface (102A). The second ferrite core (100B) includes a second engagement surface (102B). As depicted in FIG. 1, in a ferrite core assembly (10), the first ferrite core (100A) is arranged on the second ferrite core (100B) according to the mounting direction (2) such that the first engagement surface (102A) faces the second engagement surface (102B). The first engagement surface (102A) makes partial surface contact with the second engagement surface (102B). More precisely, the first engagement surface (102A) makes surface contact with the second engagement surface (102B) except where the channels (26, 28) are present. Each channel (26, 28) is defined between the first engagement surface (102A) and the second engagement surface (102B). In particular, each ferrite core (100A, 100B) includes two conductor grooves (104, 106) that extend along the extension direction (1) from the front (12) to the rear (14), respectively. In the first embodiment, the conductor grooves (104, 106) are formed by rectangular grooves. Each channel (26, 28) is formed by the conductor groove (104A, 106A) of the first ferrite core (100A) facing the corresponding conductor grooves (104B, 106B) of the second ferrite core (100B). As illustrated in FIG. 2, each conductor groove (104B, 106B) is recessed into the second ferrite core (100B) from the interlocking surface (102B) to a depth equal to half the width (32) of the rectangular cross-section of the channels (26, 28). The groove width (32) of each conductor groove (104B, 106B) corresponds to the length (30) of the rectangular cross-section of the channels (26, 28). The same applies to the conductor grooves (104A, 106A) of the first ferrite core (100A).

[0038] The first engagement surface (102A) and the second engagement surface (102B) are configured to provide contact of the first ferrite core (100A) with the second ferrite core (100B) along the transverse direction (3). The transverse direction (3) is perpendicular to the extension direction (1) and the mounting direction (2), respectively. The transverse direction (3) is parallel to the X-axis of the orthogonal coordinate system shown in FIG. 1.

[0039] Each of the first ferrite core (100A) and the second ferrite core (100B) is provided with a respective locking ridge (108A, 108B). Each locking ridge (108A, 108B) protrudes perpendicularly from each interlocking surface (102A, 102B) and extends longitudinally along the extension direction (1), particularly from the front (12) to the rear (14). Each locking ridge (108A, 108B) has a solid rectangular cross-section in a plane parallel to the front (12).

[0040] As illustrated in FIG. 2, the locking ridge (108B) of the second ferrite core (100B) has one outer sidewall (110B) flush with the side (18). In other words, the outer sidewall (110B) is formed as an extension of the side (18). The locking ridge (108B) includes one inner sidewall (112B) facing the outer sidewall (110B). Both sidewalls (110B, 112B) extend in the (YZ) plane. The locking ridge (108B) includes a top surface (114B). The top surface (114B) connects the outer sidewall (110B) to the inner sidewall (112B). The top surface (114B) extends in the (XZ) plane. The same description applies to the locking ridge (108A) of the first ferrite core (100A).

[0041] Furthermore, each of the first ferrite core (100A) and the second ferrite core (100B) is provided with a respective locking recess (116A, 116B). Each locking recess (116A, 116B) is deepened vertically from each interlocking surface (102A, 102B) and extends longitudinally along the extension direction (1), particularly from the front (12) to the rear (14).

[0042] As illustrated in FIG. 2, the locking recess (116B) of the second ferrite core (100B) is open to a side (22) facing the side (18). Thus, the locking recess (116B) includes only one side wall (118B). The side wall (118B) extends in the (YZ) plane. The side wall (118B) of the locking recess (116B) is parallel to the side (22). The side wall (118B) of the locking recess (116B) is parallel to the inner side wall (112B) of the locking ridge (108B). The locking recess (116B) is provided with a bottom surface (120B). The bottom surface (120B) extends in the (XZ) plane. The lowest surface (120B) of the locking recess (116B) is parallel to the upper surface (114B) of the locking ridge (108B). The same description applies to the locking recess (116A) of the first ferrite core (100A).

[0043] The width (122B) of the locking ridge (108B) corresponds to the width (124B) of the locking recess (116B). The width (122B) of the locking ridge (108B) is defined along the X-axis between the outer sidewall (110B) and the inner sidewall (112B) of the locking ridge (108B). The width (124B) of the locking recess (116B) is defined along the X-axis at the lowest surface (120B) between the side (22) and the sidewall (118B). The same description applies to the first ferrite core (100A).

[0044] The height (126B) of the locking ridge (108B) corresponds to the depth (128B) of the locking recess (116B). The height (126B) of the locking ridge (108B) is defined along the Y-axis between the second engagement surface (102B) and the uppermost surface (114B) of the locking ridge (108B). The depth (128B) of the locking recess (116B) is defined along the Y-axis between the second engagement surface (102B) and the lowermost surface (120B) of the locking recess (116B). The same description applies to the first ferrite core (100A).

[0045] In the ferrite core assembly (10), the uppermost surface (114A) of the first ferrite core (100A) is in surface contact with the lowermost surface (120B) of the second ferrite core (100B). The lowermost surface (120A) of the first ferrite core (100A) is in surface contact with the uppermost surface (114B) of the second ferrite core (100B).

[0046] The locking ridge (108A) of the first ferrite core (100A) and the locking recess (116B) of the second ferrite core (100B), respectively, and the locking ridge (108B) of the second ferrite core (100B) and the locking recess (116A) of the first ferrite core (100A) have complementary shapes. As shown in FIG. 1, the locking ridge (108A) of the first ferrite core (100A) is mutually locked with the locking recess (116B) of the second ferrite core (100B). The locking recess (116A) of the first ferrite core (100A) is mutually locked with the locking ridge (108B) of the second ferrite core (100B). This mutually locked arrangement prevents displacement of the first ferrite core (100A) relative to the second ferrite core (100B) in the direction indicated by the arrow indicating the transverse direction (3). In particular, contact between the inner side wall (112A) of the locking ridge (108A) of the first ferrite core (100A) and the side wall (118B) of the locking recess (116B) of the second ferrite core (100B) blocks movement of the first ferrite core (100A) relative to the second ferrite core (100B) in the direction indicated by the arrow indicating the transverse direction (3). Similarly, the contact between the side wall (118A) of the locking recess (116A) of the first ferrite core (100A) and the inner side wall (112B) of the locking ridge (108B) of the second ferrite core (100B) blocks the movement of the first ferrite core (100A) relative to the second ferrite core (100B) in the direction indicated by the arrow indicating the transverse direction (3). Second embodiment

[0047] FIG. 3 illustrates a ferrite core assembly (20) according to a second embodiment.

[0048] Elements having the same reference numerals that have already been described and exemplified in FIGS. 1 and FIGS. 2 will not be described in detail again, but their description above is referenced.

[0049] The ferrite core assembly (20) differs from the ferrite core assembly (10) in that the channels (226, 228) of the ferrite core assembly (20) each have a hollow circular cross section in a plane parallel to the front surface (12) rather than a hollow rectangular cross section. Each channel (226, 228) is defined between the first engagement surface (102A) and the second engagement surface (102B). In particular, each ferrite core (100A, 100B) includes two conductor grooves (204, 206) each extending along the extension direction (1) from the front surface (12) to the rear surface (14). In a second embodiment, the conductor grooves (204, 206) are each formed as semicircular grooves. Each channel (226, 228) has a diameter (230). Each channel (226, 228) is formed by the conductor grooves (204A, 206A) of the first ferrite core (100A) facing the corresponding conductor grooves (204B, 206B) of the second ferrite core (100B). As shown in FIG. 4, each conductor groove (204B, 206B) is concave into the second ferrite core (100B) from the interlocking surface (102B).

[0050] The channels (226, 228) are configured to accommodate a wire or cable with a circular cross section. The volume of the hollow channels (26, 28) according to the first embodiment may be smaller than the volume of the hollow channels (226, 228) according to the second embodiment. Thus, the overall size of the ferrite core assembly (10) may be advantageously reduced with respect to the overall size of the ferrite core assembly (20). Third embodiment

[0051] FIG. 5 illustrates a ferrite core assembly (30) according to a third embodiment.

[0052] Elements having the same reference numerals that have already been described and exemplified in FIGS. 1 and FIGS. 2 will not be described in detail again, but their description above is referenced.

[0053] According to the present invention, a ferrite core assembly (30) comprises a first ferrite core (300A) and a second ferrite core (300B). The first ferrite core (300A) comprises a first interlocking surface (302A). The second ferrite core (300B) comprises a second interlocking surface (302B). As depicted in FIG. 5, in the ferrite core assembly (30), the first ferrite core (300A) is arranged on the second ferrite core (300B) according to the mounting direction (2) such that the first interlocking surface (302A) faces the second interlocking surface (302B).

[0054] In the third embodiment, as in the first and second embodiments, the first ferrite core (300A) and the second ferrite core (300B) have the same shape. Since the two ferrite cores (300A, 300B) are identical, only one ferrite core (300B) is depicted in FIG. 6. The description of the second ferrite core (300B) shown in FIG. 6 applies equally to the first ferrite core (300A).

[0055] The ferrite core assembly (30) comprises two distinct channels (26, 28). The channels (26, 28) are defined between the first engagement surface (302A) and the second engagement surface (302B). Each channel (26, 28) has a rectangular cross-section in a plane parallel to the front surface (12), i.e., in the (XY) plane. On the front surface (12), each channel (26, 28) is chamfered inward toward the rear surface (14) and each channel (26, 28) is chamfered inward toward the front surface (12). This prevents sharp edges that could scratch or damage the electrical terminal while inserting the electrical terminal into the ferrite core assembly. Each channel (26, 28) is dimensioned to accommodate the electrical terminal. In particular, the channels (26, 28) are configured to accommodate an electrical terminal with a rectangular cross-section.

[0056] The first engagement surface (302A) and the second engagement surface (302B) are configured to provide contact of the first ferrite core (300A) with respect to the second ferrite core (300B) along the transverse direction (3). As mentioned in relation to the first embodiment, the transverse direction (3) is perpendicular to the extension direction (1) and the mounting direction (2), respectively. The transverse direction (3) is parallel to the X-axis of the orthogonal coordinate system shown in FIG. 5.

[0057] In a third embodiment, the first ferrite core (300A) and the second ferrite core (300B) are each provided with two locking ridges (304, 306). Thus, the first ferrite core (300A) is provided with a first locking ridge (304A) and a second locking ridge (306A). Similarly, the second ferrite core (300B) is provided with a first locking ridge (304B) and a second locking ridge (306B). Each locking ridge (304A, 306A, 304B, 306B) has a solid rectangular cross-section in a plane parallel to the front surface (12).

[0058] Each first locking ridge (304A, 304B) protrudes perpendicularly from each interlocking surface (302A, 302B) and extends longitudinally along the extension direction (1), particularly from the front (12) to the rear (14). As better illustrated in FIG. 6, the first locking ridge (304B) of the second ferrite core (300B) has one outer sidewall (308B) coplanar with the side (18). In other words, the outer sidewall (308B) is formed as an extension of the side (18). The first locking ridge (304B) includes one inner sidewall (310B) opposite to the outer sidewall (308B). Both sidewalls (308B, 310B) extend in the (YZ) plane. The first locking ridge (304B) includes a top surface (312B). The top surface (312B) connects the outer sidewall (308B) to the inner sidewall (310B). The top surface (312B) extends in the (XZ) plane. The same description applies to the first locking ridge (304A) of the first ferrite core (300A).

[0059] Each second locking ridge (306A, 306B) protrudes perpendicularly from each interlocking surface (302A, 302B) and extends longitudinally along the extension direction (1), particularly from the front (12) to the rear (14). As better illustrated in FIG. 6 with respect to the second ferrite core (300B), the second locking ridge (306B) of the second ferrite core (300B) is positioned equidistant from the side (22) and the inner side wall (310B) of the first locking ridge (304B). The second locking ridge (306B) extends parallel to the first ridge (304B) along the extension direction (1). The second locking ridge (306B) includes two opposing side walls (314B, 316B). Both side walls (314B, 316B) extend in the (YZ) plane. The second locking ridge (306B) includes a top surface (318B). The top surface (318B) connects the two side walls (314B, 316B). The top surface (318B) extends in the (XZ) plane. The same description applies to the second locking ridge (306A) of the first ferrite core (300A).

[0060] In the example illustrated in FIGS. 5 and 6, the width (320B) of the first locking ridge (304B) corresponds to the width (322B) of the second locking ridge (306B). The width (320B) of the first locking ridge (304B) is defined along the X-axis between the outer sidewall (308B) and the inner sidewall (310B) of the first locking ridge (304B). The width (322B) of the second locking ridge (306B) is defined along the X-axis between the two walls (314B, 316B). The same description applies to the first ferrite core (300A).

[0061] In a variation of the third embodiment not illustrated, the width (320A, 320B) of the first locking ridge (304A, 304B) is different from the width (322A, 322B) of the second locking ridge (306A, 306B).

[0062] The height (324B) of the first locking ridge (304B) corresponds to the height (326B) of the second locking ridge (306B). The same description applies to the first ferrite core (300A). These dimensions enable the top surface (312B) of the first locking ridge (304B) and the top surface (318B) of the second locking ridge (306B) to each make surface contact with the first interlocking surface (302A). Similarly, the top surface (312A) of the first locking ridge (304A) and the top surface (318A) of the second locking ridge (306A) to each make surface contact with the second interlocking surface (302B).

[0063] The heights (324B, 326B) define the respective heights of the rectangular channels (26, 28). The length (328) of the rectangular channel (26) is defined along the X-axis between the inner sidewall (310A) of the first locking ridge (304A) and the sidewall (316B) of the second locking ridge (306B). The length (330) of the rectangular channel (28) is defined along the X-axis between the sidewall (316A) of the second locking ridge (306A) and the inner sidewall (310B) of the first locking ridge (304B). The length (328) is equal to the length (330). The lengths (328, 330) are each greater than the widths (324A, 324B, 326A, 326B). The lengths (328, 330) are parallel to the X-axis of the orthogonal coordinate system shown in FIG. 5, while the widths (324A, 324B, 326A, 326B) are parallel to the Y-axis of the system.

[0064] In the ferrite core assembly (30) according to the third embodiment, the side wall (314A) of the second locking ridge (306A) of the first ferrite core (300A) comes into contact with the side wall (314B) of the second locking ridge (306B) of the second ferrite core (300B) along the transverse direction (3). The side wall (314A) and the side wall (314B) are in surface contact from the front (12) to the rear (14).

[0065] In the third embodiment, displacement of the first ferrite core (300A) relative to the second ferrite core (300B) is prevented in the direction indicated by the arrow indicating the transverse direction (3). In particular, contact between the side wall (314A) of the second locking ridge (306A) of the first ferrite core (300A) and the side wall (314B) of the second locking ridge (306B) of the second ferrite core (300B) blocks movement of the first ferrite core (300A) relative to the second ferrite core (300B) in the direction indicated by the arrow indicating the transverse direction (3). Fourth embodiment

[0066] FIG. 7 illustrates a ferrite core assembly (40) according to a fourth embodiment.

[0067] Elements having the same reference numerals that have already been described and exemplified in FIGS. 1 and FIGS. 2 will not be described in detail again, but their description above is referenced.

[0068] According to the present invention, a ferrite core assembly (40) comprises a first ferrite core (400A) and a second ferrite core (400B). The first ferrite core (400A) comprises a first interlocking surface (402A). The second ferrite core (400B) comprises a second interlocking surface (402B). As depicted in FIG. 7, in the ferrite core assembly (40), the first ferrite core (400A) is arranged on the second ferrite core (400B) according to the mounting direction (2) such that the first interlocking surface (402A) faces the second interlocking surface (402B).

[0069] In the fourth embodiment, as in the first, second, and third embodiments, the first ferrite core (400A) and the second ferrite core (400B) have the same shape. Since the two ferrite cores (400A, 400B) are identical, only one ferrite core (400B) is depicted in FIG. 8. The description of the second ferrite core (400B) shown in FIG. 8 applies equally to the first ferrite core (400A).

[0070] The ferrite core assembly (40) comprises two distinct channels (26, 28). The channels (26, 28) are defined between the first engagement surface (402A) and the second engagement surface (402B). Each channel (26, 28) has a rectangular cross-section in a plane parallel to the front surface (12), i.e., in the (XY) plane. On the front surface (12), each channel (26, 28) is chamfered inward toward the rear surface (14) and each channel (26, 28) is chamfered inward toward the front surface (12). This prevents sharp edges that could scratch or damage the electrical terminal while inserting the electrical terminal into the ferrite core assembly. Each channel (26, 28) is dimensioned to accommodate the electrical terminal. In particular, the channels (26, 28) are configured to accommodate an electrical terminal with a rectangular cross-section.

[0071] In the fourth embodiment, the first engagement surface (402A) and the second engagement surface (402B) provide mutual contact between the first ferrite core (400A) and the second ferrite core (400B) in opposite directions along the transverse direction (3). One direction along the transverse direction (3) is indicated by an arrow marked with reference numeral (3). The opposite direction along the transverse direction (3) is illustrated by an arrow marked with reference numeral (-3). The directions (3 and -3) along the transverse direction (3) are parallel but opposite to each other. The transverse direction (3) is perpendicular to the extension direction (1) and the mounting direction (2), respectively. The transverse direction (3) is parallel to the X-axis of the orthogonal coordinate system illustrated in FIGS. 7 and 8.

[0072] In the fourth embodiment, and as in the third embodiment, the first ferrite core (400A) and the second ferrite core (400B) are each provided with two locking ridges (404, 406).

[0073] Accordingly, the first ferrite core (400A) is provided with a first locking ridge (404A) and a second locking ridge (406A). Similarly, the second ferrite core (400B) is provided with a first locking ridge (404B) and a second locking ridge (406B). Each locking ridge (404A, 406A, 404B, 406B) has a solid rectangular cross-section in a plane parallel to the front surface (12).

[0074] Each first locking ridge (404A, 404B) protrudes vertically (i.e., along the Y-axis) from each interlocking surface (402A, 402B) and extends longitudinally along the extension direction (1) (i.e., along the X-axis), particularly from the front (12) to the rear (14).

[0075] As better illustrated in FIG. 8 with respect to the second ferrite core (400B), the first locking ridge (404B) of the second ferrite core (400B) has one outer sidewall (408B) coplanar with the side (22). In other words, the outer sidewall (408B) is formed as an extension of the side (22). The first locking ridge (404B) includes one inner sidewall (410B) facing the outer sidewall (408B). Both sidewalls (408B, 410B) extend in the (YZ) plane. The first locking ridge (404B) includes a top surface (412B). The top surface (412B) connects the outer sidewall (408B) to the inner sidewall (410B). The top surface (412B) extends in the (XZ) plane. The same description applies to the first locking ridge (404A) of the first ferrite core (400A).

[0076] Each second locking ridge (406A, 406B) protrudes vertically from each interlocking surface (402A, 402B) and extends longitudinally along the extension direction (1), particularly from the front (12) to the rear (14).

[0077] As better illustrated in FIG. 8 with respect to the second ferrite core (400B), the second locking ridge (406B) of the second ferrite core (400B) is positioned equidistant from the side (18) and the inner sidewall (410B) of the first locking ridge (404B). The second locking ridge (406B) extends parallel to the first ridge (404B) along the extension direction (1) (i.e., along the Z-axis). The second locking ridge (406B) includes two opposing sidewalls (414B, 416B). Both sidewalls (414B, 416B) extend in the (YZ) plane. The second locking ridge (406B) includes a top surface (418B). The top surface (418B) connects the two sidewalls (414B, 416B). The top surface (418B) extends in the (XZ) plane. The same description applies to the second locking ridge (406A) of the first ferrite core (400A).

[0078] The width (420B) of the first locking ridge (404B) is defined along the X-axis between the outer sidewall (408B) and the inner sidewall (410B) of the first locking ridge (404B). The width (422B) of the second locking ridge (406B) is defined along the X-axis between the two walls (414B, 416B). In the example illustrated by FIG. 8, the width (420B) of the first locking ridge (404B) corresponds to the width (422B) of the second locking ridge (406B). The same description applies to the first ferrite core (400A).

[0079] In a variation of the fourth embodiment not illustrated, the width (420A, 420B) of the first locking ridge (404A, 404B) may be different from the width (422A, 422B) of the second locking ridge (406A, 406B).

[0080] The height (424B) of the first locking ridge (404B) corresponds to the height (426B) of the second locking ridge (406B). The same description applies to the first ferrite core (400A).

[0081] In the fourth embodiment, and unlike the preceding embodiments, the first ferrite core (400A) and the second ferrite core (400B) are additionally provided with two locking recesses (428, 430) each.

[0082] As can be seen in FIG. 8 with respect to the second ferrite core (400B), the first locking recess (428B) is deepened vertically from the engagement surface (402A) (i.e., along the Y-axis) and extends longitudinally along the extension direction (1) (i.e., along the Z-axis). The first locking recess (428B) has a depth indicated by reference numeral (432B) in FIG. 8, which corresponds to the distance between the engagement surface (402B) and the lowest surface (434B) of the first locking recess (428B) along the Y-axis. Similarly, the second locking recess (430B) is deepened vertically from the second engagement surface (402A) (i.e., along the Y-axis) and extends longitudinally along the extension direction (1) (i.e., along the Z-axis). The second locking recess (430B) has a depth indicated by reference numeral (434B) in FIG. 8, which corresponds to the distance between the second engaging surface (402B) and the lowest surface (436B) of the second locking recess (430B) along the Y-axis. The depth (432B) of the first locking recess (428B) corresponds to the depth (434B) of the second locking recess (430B). The same description applies to the first ferrite core (400A).

[0083] The first locking recess (428B) has a width (438B). The width (438B) is defined along the X-axis between the second interlocking surface (402B) and the side wall (416B) of the second locking ridge (406B). The second locking recess (430B) has a width (440B). The width (440B) is defined along the X-axis between the second interlocking surface (402B) and the side (18).

[0084] The portion of the second engagement surface (402B) located between the first locking ridge (404B) and the first locking recess (428B) has a width indicated by reference numeral (442B) in FIG. 8. The width (442B) is defined along the X-axis between the inner sidewall (410B) and the first locking recess (428B). The portion of the second engagement surface (402B) located between the second locking ridge (406B) and the side (18) has a width indicated by reference numeral (444B) in FIG. 8. The width (444B) is defined along the X-axis between the sidewall (414B) and the second locking recess (430B). The widths (442A, 442B, 444A, 444B) (collectively referred to as 442 and 444) have the same value.

[0085] The widths (442, 444) correspond to the widths of the rectangular channels (26, 28). The heights (424, 426) of the locking ridges (404, 406) correspond to the lengths of the rectangular channels (26, 28). The heights (424, 426) are greater than the widths (442, 444).

[0086] In the fourth embodiment, all lengths of the two rectangular channels (26, 28) are arranged parallel to each other and parallel to the mounting direction (2) (i.e., the Y-axis). Consequently, the orientation of the rectangular channels (26, 28) in the fourth embodiment differs from the orientation of the first and third embodiments, in which the widths, rather than the lengths, of the two rectangular channels are arranged parallel to each other and parallel to the mounting direction (2) (i.e., the Y-axis). The orientation in the fourth embodiment enables a more compact ferrite core assembly (40).

[0087] In the fourth embodiment, the first locking ridge (404A) of the first ferrite core (400A) is partially received in the second locking recess (430B) of the second ferrite core (400B). The first locking ridge (404A) of the first ferrite core (400A) contacts the second engaging surface (402B) along the opposing direction (-3) of the transverse direction (3). In particular, the inner side wall (410A) of the first locking ridge (404A) of the first ferrite core (400A) contacts the surface of the second engaging surface (402B) at a height (434B) along the opposing direction (-3) of the transverse direction (3). The first locking ridge (404B) of the second ferrite core (400B) is partially received in the second locking recess (430A) of the first ferrite core (400A). The first locking ridge (404B) of the second ferrite core (400B) contacts the first interlocking surface (402A) along the direction (3) of the transverse direction (3). In particular, the inner side wall (410B) of the first locking ridge (404B) of the second ferrite core (400B) contacts the surface at the height (434A) of the first interlocking surface (402A) along the direction (3) of the transverse direction (3).

[0088] The width (422A) of the second locking ridge (406A) of the first ferrite core (400A) is similar to the width (438B) of the first locking recess (428B) of the second ferrite core (400B). In particular, these widths (422A, 438B) are adjusted so that the second locking ridge (406A) of the first ferrite core (400A) can be received in the first locking recess (428B) of the second ferrite core (400B) to provide a shape-fit connection. In a fourth embodiment, the second locking ridge (406A) of the first ferrite core (400A) is partially received in the first locking recess (428B) of the second ferrite core (400B). The second locking ridge (406A) of the first ferrite core (400A) is mutually locked with the first locking recess (428B) of the second ferrite core (400B). The shape-fit connection is formed in two opposing directions (3 and -3) along the transverse direction (3) between the second locking ridge (406A) of the first ferrite core (400A) and the first locking recess (428B) of the second ferrite core (400B). The side wall (416A) of the second locking ridge (406A) of the first ferrite core (400A) abuts against the side wall (416B) of the second locking ridge (406B) of the second ferrite core (400B) along the direction (3) of the transverse direction (3). The side wall (414A) of the second locking ridge (406A) of the first ferrite core (400A) contacts the surface of the second interlocking surface (402B) at height (428A) along the opposing direction (-3) of the transverse direction (3).

[0089] Similarly, the second locking ridge (406B) of the second ferrite core (400B) is partially received in the first locking recess (428A) of the first ferrite core (400A). The second locking ridge (406B) of the second ferrite core (400B) is mutually locked with the first locking recess (428A) of the first ferrite core (400A). The form-fit connection is formed in two opposing directions (3 and -3) along the transverse direction (3) between the second locking ridge (406B) of the second ferrite core (400B) and the first locking recess (428A) of the first ferrite core (400A). The side wall (416B) of the second locking ridge (406B) of the second ferrite core (400B) contacts the side wall (416A) of the second locking ridge (406A) of the first ferrite core (400A) along the opposing direction (-3) of the transverse direction (3). The side wall (414B) of the second locking ridge (406B) of the second ferrite core (400B) contacts the surface of the height (428B) of the first interlocking surface (402A) along the direction (3) of the transverse direction (3). Fifth embodiment

[0090] FIG. 9 illustrates a ferrite core assembly (50) according to a fifth embodiment.

[0091] Elements having the same reference numerals that have already been described and exemplified in FIGS. 1 and FIGS. 2 will not be described in detail again, but their description above is referenced.

[0092] According to the present invention, a ferrite core assembly (50) comprises a first ferrite core (500A) and a second ferrite core (500B). The first ferrite core (500A) comprises a first interlocking surface (502A). The second ferrite core (500B) comprises a second interlocking surface (502B). As depicted in FIG. 9, in the ferrite core assembly (50), the first ferrite core (500A) is arranged on the second ferrite core (500B) according to the mounting direction (2) such that the first interlocking surface (502A) faces the second interlocking surface (502B).

[0093] Unlike the prior embodiments, in the fifth embodiment, the first ferrite core (500A) has a shape that is complementary but different from the shape of the second ferrite core (500B). The exploded view of FIG. 10 illustrates both the first ferrite core (500A) and the second ferrite core (500B). FIG. 9 and FIG. 10 are referenced below.

[0094] The ferrite core assembly (50) comprises two distinct channels (26, 28). Each channel (26, 28) has a rectangular cross-section in a plane parallel to the front (12), i.e., in the (XY) plane. On the front (12), each channel (26, 28) is chamfered at least partially inward toward the rear (14) and each front (12). This prevents sharp edges that could scratch or damage the electrical terminal while inserting the electrical terminal into the ferrite core assembly. Each channel (26, 28) is dimensioned to accommodate the electrical terminal. In particular, the channels (26, 28) are configured to accommodate an electrical terminal with a rectangular cross-section.

[0095] In the fifth embodiment, as in the fourth embodiment, the first engagement surface (502A) and the second engagement surface (502B) provide mutual contact between the first ferrite core (500A) and the second ferrite core (500B) in opposite directions along the transverse direction (3). One direction along the transverse direction (3) is indicated by an arrow marked with reference numeral (3). The opposite direction along the transverse direction (3) is indicated by an arrow marked with reference numeral (-3). The directions (3 and -3) along the transverse direction (3) are parallel but opposite to each other. The transverse direction (3) is perpendicular to the extension direction (1) and the mounting direction (2), respectively. The transverse direction (3) is parallel to the X-axis of the orthogonal coordinate system shown in FIGS. 9 and FIGS. 10.

[0096] The first ferrite core (500A) is provided with two locking recesses (504A, 506A). In the example illustrated by FIGS. 9 and 10, the two locking recesses (504A, 506A) have the same shape and dimensions. Accordingly, the structural description below for one of the locking recesses (504A, 506A) applies to the other.

[0097] The locking recesses (504A, 506A) are each deepened perpendicularly from the interlocking surface (502A) (i.e., along the Y-axis) and extended longitudinally along the extension direction (1) (i.e., along the Z-axis). The locking recesses (504A, 506A) each have a depth indicated by the reference numeral (508A). For the first locking recess (504A), the depth (508A) is defined along the Y-axis between the interlocking surface (502A) and the lowest surface (510A) of the first locking recess (504A). For the second locking recess (506A), the depth (508A) is defined along the Y-axis between the interlocking surface (502A) and the lowest surface (512A) of the second locking recess (506A).

[0098] The first locking recess (504A) includes two opposing walls (514A, 516A). The two opposing walls (514A, 516A) extend in respective planes parallel to the (YZ) plane. The first wall (514A) is the wall closest to the side wall (22). The second wall (516A) is positioned opposite the first wall (514A). The two opposing walls (514A, 516A) are separated by a distance along the X-axis, which defines the width (518A) of the first locking recess (504A).

[0099] The second locking recess (506A) includes two opposing walls (520A, 522A). The two opposing walls (520A, 522A) extend in respective planes parallel to the (YZ) plane. The first wall (520A) is the wall closest to the side wall (18). The second wall (522A) is positioned opposite the first wall (520A). The two opposing walls (520A, 522A) are separated by a distance along the X-axis, which defines the width (518A) of the second locking recess (506A). The first locking recess (504A) and the second locking recess (506A) have the same width.

[0100] The second ferrite core (500B) is provided with two locking ridges (524B, 526B). In the example illustrated by FIGS. 9 and 10, the two locking ridges (524B, 526B) have the same shape and dimensions. Accordingly, the structural description below for one of the locking ridges (524B, 526B) applies to the other.

[0101] Each locking ridge (524B, 526B) has a solid rectangular cross-section in a plane parallel to the front (12). Each locking ridge (524B, 526B) protrudes perpendicularly (i.e., along the Y-axis) from the second interlocking surface (402B) and extends longitudinally along the extension direction (1) (i.e., along the X-axis), particularly from the front (12) to the rear (14).

[0102] The first locking ridge (524B) includes two opposing walls (527B, 528B). The two opposing walls (527B, 528B) extend in respective planes parallel to the (YZ) plane. The first wall (527B) is the wall closest to the side wall (22). The second wall (528B) is positioned opposite the first wall (527B). The two opposing walls (527B, 528B) are separated by a distance along the X-axis, which defines the width (530B) of the first locking ridge (524B). The first locking ridge (524B) includes a top surface (532B). The top surface (532B) connects the two opposing walls (527B, 528B). The top surface (532B) extends in the (XZ) plane. The top surface (532B) has a width corresponding to the width (530B). The first locking ridge (524B) has a height (534B). The height (534B) is defined along the Y-axis between the second interlocking surface (502B) and the top surface (532B) of the first locking ridge (524B).

[0103] The second locking ridge (526B) includes two opposing walls (536B, 538B). The two opposing walls (536B, 538B) extend in respective planes parallel to the (YZ) plane. The first wall (536B) is the wall closest to the side wall (18). The second wall (538B) is positioned opposite the first wall (536B). The two opposing walls (536B, 538B) are separated by a distance along the X-axis, which defines the width (530B) of the second locking ridge (526B). The first locking ridge (524B) and the second locking ridge (526B) have the same width (530B). The second locking ridge (526B) includes an uppermost surface (540B). The top surface (540B) connects two opposing walls (536B, 538B). The top surface (540B) extends in the (XZ) plane. The top surface (540B) has a width corresponding to the width (530B). The second locking ridge (526B) has the same height (534B) as the height (534B) of the first locking ridge (524B).

[0104] In the fifth embodiment, the rectangular channel (26) is defined between the first locking recess (504A) of the first ferrite core (500A) and the uppermost surface (532B) of the first locking ridge (524B) of the second ferrite core (500B). More precisely, the rectangular channel (26) has a first surface defined by the uppermost surface (532B) of the first locking ridge (524B) of the second ferrite core (500B), a second surface defined by the lowermost surface (510A) of the first locking recess (504A) of the first ferrite core (500A), a third surface defined by the first wall (514A) of the first locking recess (504A) of the first ferrite core (500A), and a fourth surface defined by the second wall (516A) of the first locking recess (504A) of the first ferrite core (500A). The rectangular channel (28) is defined between the second locking recess (506A) of the first ferrite core (500A) and the uppermost surface (540B) of the second locking ridge (526B) of the second ferrite core (500B). More precisely, the rectangular channel (28) has a first surface defined by the uppermost surface (540B) of the second locking ridge (526B) of the second ferrite core (500B), a second surface defined by the lowermost surface (512A) of the second locking recess (506A) of the first ferrite core (500A), a third surface defined by the first wall (520A) of the second locking recess (506A) of the first ferrite core (500A), and a fourth surface defined by the second wall (522A) of the second locking recess (506A) of the first ferrite core (500A).

[0105] The depth (508A) of each locking recess (504A, 506A) is greater than the height (534B) of each locking ridge (524B, 526B). In particular, the difference between the depth (508A) of each locking recess (504A, 506A) and the height (534B) of each locking ridge (524B, 526B) forms a gap that enables the insertion of electrical terminals into each channel (26, 28).

[0106] In the fifth embodiment, the locking recesses (504A, 506A) and locking ridges (524B, 526B) are arranged in the ferrite core assembly (50) as illustrated in FIG. 9 such that the first locking ridge (524B) of the second ferrite core (500B) is received in the first locking recess (504A) of the first ferrite core (500A). The second locking ridge (526B) of the second ferrite core (500B) is received in the second locking recess (506A) of the first ferrite core (500A). The width (518A) of the locking recesses (504A, 506A) may be slightly larger than the width (530B) of the locking ridges (524B, 526B) to enable the locking ridges (524B, 526B) to be accommodated within each of the locking recesses (504A, 506A).

[0107] Accordingly, in the fifth embodiment, the first locking ridge (524B) of the second ferrite core (500B) is partially received in the first locking recess (504A) of the first ferrite core (500A) and is mutually locked. A first shape-fit connection is formed between the first locking recess (504A) of the first ferrite core (500A) and the first locking ridge (524B) of the second ferrite core (500B). The second locking ridge (526B) of the second ferrite core (500B) is partially received in the second locking recess (506A) of the first ferrite core (500A) and is mutually locked. A second shape-fit connection is formed between the second locking recess (506A) of the first ferrite core (500A) and the second locking ridge (526B) of the second ferrite core (500B).

[0108] The wall (514A) of the first locking recess (504A) of the first ferrite core (500A) comes into contact with the wall (527B) of the first locking ridge (524B) of the second ferrite core (500B) along the direction (3) of the transverse direction (3).

[0109] The wall (516A) of the first locking recess (504A) of the first ferrite core (500A) comes into contact with the wall (528B) of the first locking ridge (524B) of the second ferrite core (500B) along the opposing direction (-3) of the transverse direction (3).

[0110] The wall (522A) of the second locking recess (506A) of the first ferrite core (500A) comes into contact with the wall (538B) of the second locking ridge (526B) of the second ferrite core (500B) along the direction (3) of the transverse direction (3).

[0111] The wall (520A) of the second locking recess (506A) of the first ferrite core (500A) comes into contact with the wall (536B) of the second locking ridge (526B) of the second ferrite core (500B) along the opposing direction (-3) of the transverse direction (3).

[0112] Consequently, in the fifth embodiment, the first engaging surface (502A) having locking recesses (504A, 506A) and the second engaging surface (502B) having locking ridges (524B, 526B) provide mutual contact between the first ferrite core (500A) and the second ferrite core (500B) in both opposing directions (3 and -3) along the transverse direction (3). 6th embodiment

[0113] FIG. 11 illustrates a ferrite core assembly (60) according to a sixth embodiment.

[0114] Elements having the same reference numerals that have already been described and exemplified in FIGS. 1 and FIGS. 2 will not be described in detail again, but their description above is referenced.

[0115] According to the present invention, a ferrite core assembly (60) comprises a first ferrite core (600A) and a second ferrite core (600B). The first ferrite core (600A) comprises a first interlocking surface (602A). The second ferrite core (600B) comprises a second interlocking surface (602B). In the ferrite core assembly (60), the first ferrite core (600A) is arranged on the second ferrite core (600B) according to the mounting direction (2) such that the first interlocking surface (602A) faces the second interlocking surface (602B).

[0116] In the sixth embodiment, as in the first, second, third, and fourth embodiments, the first ferrite core (600A) and the second ferrite core (600B) have the same shape. Therefore, the description of one of the ferrite cores (600A, 600B) applies equally to the other ferrite core (600A, 600B).

[0117] The first ferrite core (600A) is provided with a first lateral locking ridge (604A) and a second lateral locking ridge (606A). The first and second lateral locking ridges (604A, 606A) each extend from the rear (14) and extend only partially toward the front (12) along the extension direction (1) (i.e., the X-axis). Both the first lateral locking ridge (604A) and the second lateral locking ridge (606A) are coplanar with the rear (14) and the side walls (18, 22), but not coplanar with the front (12).

[0118] The second ferrite core (600B) is provided with a first lateral locking ridge (604B) and a second lateral locking ridge (606B). The first and second lateral locking ridges (604B, 606B) each extend from the front (12) and extend only partially toward the rear (14) along the extension direction (1) (i.e., the X-axis). Both the first lateral locking ridge (604B) and the second lateral locking ridge (606B) are coplanar with the front (12) and the side walls (18, 22), but not coplanar with the rear (14).

[0119] In the first ferrite core (600A), the first lateral locking ridge (604A) comprises two side walls (610A, 612A). The outer side wall (610A) is coplanar with the side (22). The inner side wall (612A) is opposite to the outer side wall (610A). The side walls (610A, 612A) extend in the (YZ) plane. The first lateral locking ridge (604A) is provided with a top surface (614A). The top surface (614A) connects the two side walls (610A, 612A). The top surface (614A) extends in the (XZ) plane. The top surface (614A) has a width (608A). The width (608A) is defined along the X-axis between the inner sidewall (612A) and the outer sidewall (610A). The same description applies to the second ferrite core (600B), and the above reference numerals are replaced with the Latin letter "B".

[0120] In the first ferrite core (600A), the second lateral locking ridge (606A) comprises two side walls (616A, 618A). The outer side wall (616A) is coplanar with the side (18). The inner side wall (618A) is opposite to the outer side wall (616A). The side walls (616A, 618A) extend in the (YZ) plane. The second lateral locking ridge (606A) is provided with a top surface (620A). The top surface (620A) connects the two side walls (616A, 618A). The top surface (620A) extends in the (XZ) plane. The top surface (620A) has a width (608A). In the examples of FIGS. 11 and 12, the width (608A) of the first lateral locking ridge (604A) is the same as the width (608A) of the second lateral locking ridge (606A). The same description applies to the second ferrite core (600B), and the above reference numerals are replaced with the Latin letter "B".

[0121] The width (608A) of each of the lateral locking ridges (604A, 606A) is the same as the width (608B) of each of the lateral locking ridges (604B, 606B).

[0122] The first ferrite core (600A) further includes a central locking ridge (622A). The central locking ridge (622A) extends from the rear (14) and extends only partially toward the front (12) along the extension direction (1) (i.e., X-axis). The central locking ridge (622A) extends toward the front (12) along the extension direction (1) (i.e., X-axis) until two lateral locking ridges (604A, 606A) begin. The central locking ridge (622A) includes two side walls (624A, 626A). The side walls (624A, 626A) extend in the (YZ) plane. The central locking ridge (622A) is provided with a top surface (628A). The top surface (628A) connects the two side walls (624A, 626A). The top surface (628A) extends in the (XZ) plane. The top surface (628A) has a width (630A). In the examples of FIGS. 11 and 12, the width (630A) of the central locking ridge (622A) is equal to the width (608A) of the lateral locking ridges (604A, 606A). The front of the central locking ridge (622A) corresponds to the rear (14) of the ferrite core assembly (60). The rear (632A) of the central locking ridge (622A) faces the rear (14). The rear (632A) extends in the (XY) plane.

[0123] Similarly, the second ferrite core (600B) includes a central locking ridge (622B). The central locking ridge (622B) extends from the front (12) and extends only partially toward the rear (14) along the extension direction (1) (i.e., X-axis). The central locking ridge (622B) extends toward the rear (14) along the extension direction (1) (i.e., X-axis) until two lateral locking ridges (604B, 606B) begin. The central locking ridge (622B) includes two side walls (624B, 626B). The side walls (624B, 626B) extend in the (YZ) plane. The central locking ridge (622B) is provided with a top surface (628B). The top surface (628B) connects the two side walls (624B, 626B). The top surface (628B) extends in the (XZ) plane. The top surface (628B) has a width (630B). In the examples of FIGS. 11 and 12, the width (630B) of the central locking ridge (622B) is the same as the width (608B) of the lateral locking ridges (604B, 606B). The front of the central locking ridge (622B) corresponds to the front (12) of the ferrite core assembly (60). The rear (632B) of the central locking ridge (622B) faces the front (12). The rear (632B) extends in the (XY) plane.

[0124] The first ferrite core (600A) is further provided with two lateral locking recesses (634A, 636A) and one central locking recess (638A). The two lateral locking recesses (634A, 636A) each extend along the extension direction (1) (i.e., X-axis) from the rear (14) and extend only partially toward the front (12). The central locking recess (638A) extends along the extension direction (1) (i.e., X-axis) from the front (12) and extends only partially toward the rear (14). More specifically, the first lateral locking recess (634A) extends along the extension direction (1) (i.e., X-axis) until the first lateral locking ridge (604A) begins. The second lateral locking recess (636A) extends along the extension direction (1) (i.e., X-axis) until the second lateral locking ridge (606A) begins. The central locking recess (638A) extends along the extension direction (1) (i.e., X-axis) until the central locking ridge (622A) begins. The central locking recess (638A) is open to the front (12). The first lateral locking recess (634A) is open to the rear (14) and the side (22). The second lateral locking recess (636A) is open to the rear (14) and the side (18). The width (608A) of the first lateral locking recess (634A) of the first ferrite core (600A) corresponds to the width (608B) of the first locking ridge (604B) of the second ferrite core (600B). The width (608A) of the second lateral locking recess (636A) of the first ferrite core (600A) corresponds to the width (608B) of the second locking ridge (606B) of the second ferrite core (600B). The width (630A) of the central locking recess (638A) of the first ferrite core (600A) corresponds to the width (630B) of the central locking ridge (622B) of the second ferrite core (600B).

[0125] The second ferrite core (600B) is similarly provided with two lateral locking recesses (634B, 636B) and one central locking recess (638B). The two lateral locking recesses (634B, 636B) each extend along the extension direction (1) (i.e., X-axis) from the front (12) and extend only partially toward the rear (14). The central locking recess (638B) extends along the extension direction (1) (i.e., X-axis) from the rear (14) and extends only partially toward the front (12). More specifically, the first lateral locking recess (634B) extends along the extension direction (1) (i.e., X-axis) until the first lateral locking ridge (604B) begins. The second lateral locking recess (636B) extends along the extension direction (1) (i.e., X-axis) until the second lateral locking ridge (606B) begins. The central lateral locking recess (638B) extends along the extension direction (1) (i.e., X-axis) until the central locking ridge (622B) begins. The central locking recess (638B) is open to the rear (14). The first lateral locking recess (634B) is open to the front (12) and the side (22). The second lateral locking recess (636B) is open to the front (12) and the side (18). The width (608B) of the first lateral locking recess (634B) of the first ferrite core (600B) corresponds to the width (608A) of the first locking ridge (604A) of the first ferrite core (600A). The width (608B) of the second lateral locking recess (636B) of the second ferrite core (600B) corresponds to the width (608A) of the second locking ridge (606A) of the first ferrite core (600A). The width (630B) of the central locking recess (638B) of the second ferrite core (600B) corresponds to the width (630A) of the central locking ridge (622A) of the first ferrite core (600A).

[0126] A rectangular channel (26) is defined between the first engagement surface (602A), the second engagement surface (602B), the inner side wall (612A), and the side wall (626B). A rectangular channel (28) is defined between the first engagement surface (602A), the second engagement surface (602B), the inner side wall (618A), and the side wall (624B). The largest dimension of each rectangular channel (26) extends along the mounting direction (2), that is, in the same direction of extension as the locking ridges (604A, 606A, 622A, 604B, 606B, 622B).

[0127] In the sixth embodiment, the first engagement surface (602A) and the second engagement surface (602B) thus provide mutual contact between the first ferrite core (600A) and the second ferrite core (600B) in opposite directions along the transverse direction (3). One direction along the transverse direction (3) is indicated by an arrow marked with reference numeral (3). The opposite direction along the transverse direction (3) is illustrated by an arrow marked with reference numeral (-3). The directions (3 and -3) along the transverse direction (3) are parallel but opposite to each other. The transverse direction (3) is perpendicular to the extension direction (1) and the mounting direction (2), respectively. The transverse direction (3) is parallel to the X-axis of the orthogonal coordinate system illustrated in FIG. 11.

[0128] In the ferrite core assembly (60), the central locking ridge (622A) is received in the central locking recess (638B) and mutually locked. This mutually locked arrangement provides a form-fit connection between the first ferrite core (600A) and the second ferrite core (600B). Displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in both opposing directions (3 and -3) along the transverse direction (3).

[0129] Similarly, as can be seen in FIG. 11, the central locking ridge (622B) is received in the central locking recess (638A) and mutually locked. This mutually locked arrangement provides a form-fit connection between the first ferrite core (600A) and the second ferrite core (600B). Displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in both opposing directions (3 and -3) along the transverse direction (3).

[0130] The first lateral locking ridge (604A) is received in the first lateral recess (634B). Displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in the direction (3) along the lateral direction (3), particularly by contact of the inner side wall (612A) with respect to the first lateral recess (634B). The second lateral locking ridge (606A) is received in the second lateral recess (636B). Displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in the direction (-3) along the lateral direction (3), particularly by contact of the inner side wall (618A) with respect to the second lateral recess (636B).

[0131] Similarly, the first lateral locking ridge (604B) is received in the first lateral recess (634A). Displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in the direction (3) along the lateral direction (3), particularly by contact of the inner sidewall (612B) with respect to the first lateral recess (634A). The second lateral locking ridge (606B) is received in the second lateral recess (636A). Displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in the direction (-3) along the lateral direction (3), particularly by contact of the inner sidewall (618B) with respect to the second lateral recess (636A).

[0132] In the sixth embodiment, the first engagement surface (602A) and the second engagement surface (602B) thus further provide mutual contact between the first ferrite core (600A) and the second ferrite core (600B) in opposite directions along the extension direction (1). One direction along the extension direction (1) is indicated by an arrow marked with reference numeral (1). The opposite direction along the extension direction (1) is indicated by an arrow marked with reference numeral (-1). The directions (1 and -1) along the extension direction (1) are parallel but opposite to each other. The extension direction (1) is perpendicular to the mounting direction (2) and the transverse direction (3), respectively. The extension direction (1) is parallel to the Z-axis of the orthogonal coordinate system shown in FIG. 11.

[0133] The displacement of the first ferrite core (600A) relative to the second ferrite core (600B) is blocked in both directions (1 and -1) along the extension direction (1), which is blocked by mutual contact between the first locking ridge (604A) and the first locking ridge (604B) along the extension direction (1), mutual contact between the second locking ridge (606A) and the second locking ridge (606B) along the extension direction (1), and mutual contact between the central locking ridge (622A) and the central locking ridge (622B) along the extension direction (1).

[0134] Each of the ferrite core assemblies (10, 20, 30, 40, 50, 60) is suitable for a pyrotechnic connector that is plugged into an electrical connector, particularly a matching connector of a safety restraint system. Assembly method

[0135] FIGS. 13a through 13d illustrate successive steps of an assembly method for assembling a ferrite core assembly, particularly a ferrite core assembly (50) according to the fifth embodiment, to an electrical connector (700). However, the assembly method depicted by FIGS. 13a through 13d is applicable to a ferrite core assembly according to any one of the embodiments described above.

[0136] As illustrated in FIG. 13a, the electrical connector (700) may be a pyrotechnic connector and is also known as a squid connector. The electrical connector (700) is configured to be plugged into a mating connector (not shown), particularly a mating connector used in safety restraint systems, along the mounting direction (2).

[0137] The electrical connector (700) includes a housing (702). The housing (702) includes a first receptacle (704) for receiving a ferrite core assembly (50). The housing (702) includes a second receptacle (706) for receiving electrical terminals (708) and wire fasteners (710) and / or cables. The electrical connector (700) includes a mating portion (712) configured to mat with a corresponding mating connector (not shown).

[0138] In step (A) of the assembly method illustrated in FIG. 13a, the first ferrite core (500A) is assembled vertically to the electrical connector (700). More precisely, the first ferrite core (500A) is inserted into the first receptacle (704) along the mounting direction (2).

[0139] As illustrated in step (B) of the assembly method shown in FIG. 13b, the side (16) of the first ferrite core (500A) is placed on the lowest surface of the receptacle (704). In step (B) of the assembly method, two electrical terminals (708) are assembled vertically to the electrical connector (700). More specifically, the first electrical terminal (708) is inserted into the first locking recess (504A) along the mounting direction (2), and the second electrical terminal (708) is inserted into the second locking recess (506A) along the mounting direction (2). The rectangular locking recesses (504A, 506B) help guide the alignment of each rectangular portion (714) of the electrical terminals (708) in the first ferrite core (500A).

[0140] During step (C) of the assembly method illustrated in FIG. 13c, the second ferrite core (500B) is inserted and assembled vertically into the electrical connector (700). More precisely, the second ferrite core (500B) is inserted into the first receptacle (704) along the mounting direction (2), and the second ferrite core (500B) is arranged on the first ferrite core (500A). Then, the first ferrite core (500A) is assembled with the second ferrite core (500B) to form a ferrite core assembly (50).

[0141] In the ferrite core assembly (50) illustrated in step (D) of the assembly method illustrated in FIG. 13d, the first engagement surface (502A) is in surface contact with the second engagement surface (502B). Electrical terminals (708) are received between the respective channels (26, 28) formed between the locking recesses (504A, 506A) of the first ferrite core (500A) and the locking ridges (524B, 526B) of the second ferrite core (500B).

[0142] In step (D) of the assembly method, the wire fixing member (710) is assembled vertically to the electrical connector (700). More precisely, the wire fixing member (710) is inserted into the second receptacle (706) along the mounting direction (2).
