Description

Technical Field

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

Background Art

[0002] A ferrite core is a component made of a ferrite material and is generally used for its magnetic properties and high electrical resistance. Ferrite cores are particularly effective in suppressing high-frequency noise and electromagnetic interference (EMI).

[0003] Ferrite cores are typically used in electrical connectors, such as detonator connectors (also known as bayonet connectors), to suppress high-frequency noise and electromagnetic interference (EMI), thereby maintaining the integrity of signal transmission.

[0004] From the prior art, such as U.S. Patent Application No. 2003 / 162444 A1 and U.S. Patent Application No. 2002 / 009924 A1, it is known to use a split ferrite core composed of two halves surrounding a cable. However, in order to maintain the effective function of the split ferrite core, it is important to prevent relative movement between the halves of the split ferrite core. Displacement due to lateral displacement or misalignment may form a gap in the magnetic path and reduce the efficiency of the ferrite in attenuating EMI. In U.S. Patent Application No. 2003 / 162444 A1, prevention of lateral movement between the halves is achieved by latch arms and retaining arms of an insulating housing that hold the ferrite member in place. In U.S. Patent Application No. 2002 / 009924 A1, the ferrite component is held within the housing by retaining clips on the housing wall that engage locking legs of the ferrite component. Further, flexible protrusions apply a holding force to hold the ferrite component against the retaining clip.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, these solutions require a specific, complex mechanism to house the mechanism. It is desirable to provide a simple and effective solution to prevent relative movement of the ferrite hemispheres along at least one direction. [Means for solving the problem]

[0006] The object of the present invention is achieved by a ferrite core assembly for electrical connectors, in particular for pyrotechnic connectors that are plugged into mating connectors of a safety restraint system. The ferrite core assembly comprises a first ferrite core including a first engagement surface and a second ferrite core including a second engagement surface, wherein the first ferrite core is positioned 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 along the extending direction is defined between the first and second engagement surfaces, the extending direction being perpendicular to the mounting direction, and the first and second engagement surfaces provide lateral contact of the first ferrite core with respect to the second ferrite core, the lateral direction being perpendicular to the mounting direction and the extending direction, respectively.

[0007] The first ferrite core abuts the second ferrite core laterally, preventing undesirable relative displacement between the two ferrite cores. This prevents the formation of gaps in the magnetic path that could occur due to the movement of the ferrite cores. The movement-preventing function in at least one direction is achieved by the mechanism of the ferrite core assembly itself, particularly by the first and second engagement surfaces, and no additional preventing means provided by the housing of the electrical connector that can accommodate the ferrite core assembly is required. This provides a simple and effective solution for preventing relative movement of two ferrite cores along at least one direction.

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

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

[0010] The mutual contact between the first and second engagement surfaces prevents displacement and misalignment of the first and second ferrite cores in both opposite directions along the lateral 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 is characterized in that the relative displacement of the first ferrite core and the second ferrite core in both opposite directions along the lateral direction is locked by the ferrite core assembly alone, and no additional latching means, locking means, or housing mechanism separate from the ferrite core assembly is used.

[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 specification, the first ferrite core defines a half-ferrite of the ferrite core assembly. The second ferrite core defines another half-ferrite of the ferrite core assembly. The first and second ferrite cores may each be machined from a ferrite block. According to one embodiment, the first ferrite core and the second ferrite core can have the same shape. This simplifies manufacturing and facilitates logistics for assembly, as only one shape is required. Alternatively, the first ferrite core may have a different shape that is complementary to the shape of the second ferrite core. This configuration facilitates specific mutual contact and improves 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 engagement surface and extends longitudinally along the extending direction. Thus, the ferrite core has a locking ridge that can engage with a corresponding mechanism to restrict relative movement along the lateral direction between the two ferrite cores, and no additional restraining means is particularly required from the housing of the electrical connector that can accommodate the ferrite core assembly. In one embodiment, at least one locking ridge may extend longitudinally along the extension direction from the front surface of the ferrite core assembly to the rear surface of the ferrite core assembly. Alternatively, at least one locking ridge may only partially extend from the front surface of the ferrite core assembly toward the rear surface of the ferrite core assembly, or from the rear surface of the ferrite core assembly toward the front surface of the ferrite core assembly.

[0014] According to one embodiment, at least one locking ridge of the first ferrite core can abut laterally against at least one locking ridge of the second ferrite core. This abutment between the two locking ridges can create more surface contact between the first and second ferrite cores, which may further restrict movement along the lateral direction.

[0015] The first and second engagement surfaces may each be provided with a guide mechanism. The guide mechanism 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 a side surface of the first or second ferrite core, the side surface being defined by a plane formed by the extending direction and the mounting direction. By providing a side wall of the locking ridge parallel to the side surface of the ferrite core, a surface perpendicular to the lateral direction is formed. This enhances the ability to restrict movement along the lateral direction. Furthermore, this parallel configuration allows the locking ridge to facilitate the positioning of the first ferrite core with respect to the second ferrite core.

[0016] According to one embodiment, at least one of the first ferrite core and the second ferrite core may have at least one locking recess that extends perpendicularly from the respective engagement surfaces of the ferrite core and longitudinally along the extending direction. The locking recess provides a defined cavity or groove for engaging with a corresponding mechanism to restrict relative movement along the lateral direction, and no additional restraining means is particularly required from the housing of an electrical connector capable of accommodating the ferrite core assembly. In one embodiment, at least one locking recess may extend longitudinally along the extending direction from the front surface of the ferrite core assembly to the rear surface of the ferrite core assembly. Alternatively, at least one locking recess may partially extend from the front of the ferrite core assembly toward the rear of the ferrite core assembly, or from the rear of the ferrite core assembly toward the front of the ferrite core assembly.

[0017] According to one embodiment, at least one locking ridge of the first ferrite core or the second ferrite core may be interlocked by being at least partially received in at least one locking recess of the second ferrite core or the first ferrite core, respectively. The interlocking engagement of the locking ridge within the locking recess forms a shape-fitting connection, thereby preventing relative movement between the first and second ferrite cores in both opposite directions along the lateral direction. This shape-fitting connection improves the stability and alignment of the ferrite core assembly. In particular, the shape-fitting connection achieves these effects without relying on an additional locking mechanism separate from the ferrite core assembly.

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

[0019] The longest dimension of the rectangular channel, measured in a plane defined by the mounting direction and lateral direction, may be parallel to the protruding direction of the locking ridge. This configuration can provide a smaller 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 lateral direction, is perpendicular to the protruding direction of the locking ridge.

[0020] According to one embodiment, the ferrite core assembly may have two separate channels, each configured to receive individual electrical terminals or cables. This arrangement allows for the isolation and alignment of electrical terminals or cables within the ferrite core assembly. The openings of each channel on the front and / or rear of the ferrite core assembly may be chamfered inward toward the interior of each channel. This reduces 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 direction of extension, and at least one channel may be partially formed by the recess. The recess may be dimensioned to accommodate an electrical terminal or cable. According to one embodiment, the recess configured to accommodate an electrical terminal or cable may correspond to a locking recess in one of the ferrite cores. According to another embodiment, the first ferrite core may include a recess or groove extending along the direction of extension. The second ferrite core may include a corresponding recess or groove extending along the direction of extension. The channel may be formed by the 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 or second ferrite core and the second engaging surface of the second ferrite or the first engaging surface of the first ferrite core, respectively. In particular, at least one channel may be formed between the locking ridge of the first or second ferrite core and the recess of the second or first ferrite core, respectively. This configuration provides a smaller solution because the locking ridge functions as a shape-fitting connection to prevent mutual displacement of the ferrite cores and simultaneously functions as a channel for receiving electrical terminals or cables. At least one channel may be at least partially defined by a sidewall of a locking ridge of one of the ferrite cores. At least one channel may be at least partially defined between a sidewall of a locking ridge of a first ferrite core and a sidewall of a locking ridge of a second ferrite core. At least one channel may be at least partially defined between two sidewalls of a 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 abutment along an extending direction of the first ferrite core with respect to the second ferrite core. The abutment along the extending direction provides additional stability to the ferrite core assembly by restricting relative movement in two directions of the first ferrite core and the second ferrite core, namely the lateral direction and the extending direction. The abutment along the extending direction of the first ferrite core with respect to the second ferrite core may be realized by the locking ridge of the first ferrite core abutting along the extending direction against a corresponding locking ridge or a corresponding locking recess of the second ferrite core.

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

[0025] The object of the present invention is also achieved by an electrical connector for a mating connector, in particular for a detonator connector, which is plugged in along an attachment direction to a mating connector of a safety restraint system. The electrical connector includes a connector housing for accommodating electrical terminals or wires, and a ferrite core assembly. The ferrite core assembly is accommodated in the connector housing. The ferrite core assembly includes at least one channel for receiving an electrical terminal or wire along an extending direction, and the extending direction is perpendicular to the mounting direction. The ferrite core assembly includes a first ferrite core including a first engaging surface and a second ferrite core including a second engaging surface. The first ferrite core is configured to be arranged on the second ferrite core along the mounting direction such that the first engaging surface faces the second engaging surface. The first engaging surface and the second engaging surface are configured to provide abutment of the first ferrite core against the second ferrite core along a lateral direction, and the lateral direction is perpendicular to the mounting direction and the extending direction respectively.

[0026] The electrical connector can be characterized in that there is no latch means in the connector housing for holding the first ferrite core against the second ferrite core. Thereby, the design of the connector housing can be simplified. The electrical connector can include a receptacle for accommodating a wire fixture.

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

[Figure 13] Figures A through D are diagrams that represent the steps in the assembly method of a ferrite core assembly. [Modes for carrying out the invention]

[0030] As used below, reference codes ending in the Latin letter "A" (such as 100A or 102A) refer to the first ferrite core, and reference codes ending in the Latin letter "B" (such as 100B or 102B) refer to the second ferrite core of the ferrite core assembly.

[0031] First Embodiment Figure 1 shows a ferrite core assembly 10 according to a first embodiment. The ferrite core assembly 10 has a rectangular parallelepiped shape. The ferrite core assembly 10 has a front surface 12 opposite the rear surface 14 along the extending direction 1. The extending direction 1 is indicated by arrow 1 and is parallel to the Z axis of the Cartesian coordinate system shown in Figure 1. The front surface 12 or the rear surface 14 has a rectangular shape. The front surface 12 and the rear surface 14 are connected by four side walls 16, 18, 20, and 22. Two side surfaces 16 and 20 are opposite each other along the Y axis of the Cartesian coordinate system shown in Figure 1. Two side surfaces 18 and 22 are opposite each other along the X axis of the Cartesian coordinate system shown in Figure 1. The side surfaces 16, 18, 20, and 22 are joined at their intersections by chamfered edges 24.

[0032] The ferrite core assembly 10 comprises two separate channels 26, 28. Each channel 26, 28 is configured to receive one electrical terminal (not shown) along the extending direction 1. The two channels 26, 28 have the same dimensions and shape. Each channel 26, 28 extends from the front 12 to the rear 14 of the ferrite core assembly 10.

[0033] 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. Each of the parallel lengths 30 is greater than the parallel widths 32. The lengths 30 are parallel to the X-axis of the Cartesian coordinate system shown in Figure 1, and the widths 32 are parallel to the Y-axis of the coordinate system.

[0034] In the first embodiment, channels 26 and 28 are positioned such that the parallel lengths 30 of the rectangular cross-section of channel 26 match the corresponding parallel lengths 30 of the rectangular cross-section of channel 28. Each channel 26 and 28 is dimensioned to receive electrical terminals. In particular, channels 26 and 28 are configured to receive electrical terminals with rectangular cross-sections.

[0035] On the front 12 or rear 14, each channel 26, 28 is chamfered inward toward the rear 14 or front 12. This prevents sharp edges that could rub against or damage the electrical terminals during insertion into the ferrite core assembly.

[0036] According to the present invention, the ferrite core assembly 10 comprises a first ferrite core 100A and a second ferrite core 100B.

[0037] 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 and 100B are identical, only one ferrite core 100B is shown in Figure 2. The description of the second ferrite core 100B shown in Figure 2 applies equally to the first ferrite core 100A.

[0038] The first ferrite core 100A includes a first engagement surface 102A. The second ferrite core 100B includes a second engagement surface 102B. In the ferrite core assembly 10, as shown in Figure 1, the first ferrite core 100A is positioned 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 is in partial surface contact with the second engagement surface 102B. More precisely, the first engagement surface 102A is in surface contact with the second engagement surface 102B except where 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, respectively, extending along the extension direction 1 from the front surface 12 to the rear surface 14. In the first embodiment, the conductor grooves 104, 106 are formed by rectangular grooves. Each channel 26, 28 is formed by the conductor grooves 104A, 106A of the first ferrite core 100A facing the corresponding conductor grooves 104B, 106B of the second ferrite core 100B. As shown in Figure 2, each conductor groove 104B, 106B is recessed into the second ferrite core 100B from the engagement surface 102B to a depth equal to half the width 32 of the rectangular cross-section of the channel 26, 28. The groove width (30) of each conductor groove 104B, 106B corresponds to the length 30 of the rectangular cross-section of the channel 26, 28. The same applies to the conductor grooves 104A and 106A of the first ferrite core 100A.

[0039] The first engagement surface 102A and the second engagement surface 102B are configured to provide contact of the first ferrite core 100A with respect to the second ferrite core 100B along the transverse direction 3. The transverse direction 3 is perpendicular to the extending direction 1 and the mounting direction 2, respectively. The transverse direction 3 is parallel to the X-axis of the Cartesian coordinate system shown in Figure 1.

[0040] Each of the first ferrite core 100A and the second ferrite core 100B is provided with locking ridges 108A and 108B, respectively. Each locking ridge 108A and 108B protrudes perpendicularly from its respective engagement surfaces 102A and 102B and extends longitudinally along the extension direction 1, particularly from the front surface 12 to the rear surface 14. Each locking ridge 108A and 108B has a solid rectangular cross-section in a plane parallel to the front surface 12.

[0041] As shown in Figure 2, the locking ridge 108B of the second ferrite core 100B has one outer wall 110B that is coplanar with the side surface 18. In other words, the outer wall 110B is formed as an extension of the side surface 18. The locking ridge 108B includes one inner wall 112B on the opposite side of the outer wall 110B. Both side walls 110B and 112B extend in the (YZ) plane. The locking ridge 108B includes a top surface 114B. The top surface 114B connects the outer wall 110B to the inner wall 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.

[0042] Furthermore, each of the first ferrite core 100A and the second ferrite core 100B is provided with locking recesses 116A and 116B, respectively. Each locking recess 116A and 116B deepens perpendicularly from its respective engaging surfaces 102A and 102B and extends longitudinally along the extending direction 1, particularly from the front surface 12 to the rear surface 14.

[0043] As shown in Figure 2, the locking recess 116B of the second ferrite core 100B opens to the side 22 opposite to the side 18. Therefore, 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 wall 112B of the locking ridge 108B. The locking recess 116B has a bottom surface 120B. The bottom surface 120B extends in the (XZ) plane. The bottom surface 120B of the locking recess 116B is parallel to the top surface 114B of the locking ridge 108B. The same description applies to the locking recess 116A of the first ferrite core 100A.

[0044] 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 wall 110B and the inner wall 112B of the locking ridge 108B. The width 124B of the locking recess 116B is defined along the X-axis between the side surface 22 and the side wall 118B at the bottom surface 120B. The same description applies to the first ferrite core 100A.

[0045] 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 top 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 bottom surface 124B of the locking recess 116B. The same description applies to the first ferrite core 100A.

[0046] In the ferrite core assembly 10, the upper surface 108A of the first ferrite core 100A is in surface contact with the bottom surface 120B of the second ferrite core 100B. The bottom surface 120A of the first ferrite core 100A is in surface contact with the upper surface 108B of the second ferrite core 100B.

[0047] The locking ridge 108A of the first ferrite core 100A and the locking recess 116B of the second ferrite core 100B, or 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 Figure 1, the locking ridge 108A of the first ferrite core 100A interlocks with the locking recess 116B of the second ferrite core 100B. The locking recess 116A of the first ferrite core 100A interlocks with the locking ridge 108B of the second ferrite core 100B. This interlocking arrangement prevents the first ferrite core 100A from being displaced relative to the second ferrite core 100B in the direction indicated by the arrow indicating lateral direction 3. In particular, the inner wall 112A of the locking ridge 108A of the first ferrite core 100A abuts against the side wall 118B of the locking recess 116B of the second ferrite core 100B, thereby preventing the first ferrite core 100A from moving relative to the second ferrite core 100B in the direction indicated by the arrow indicating lateral direction 3. Similarly, the side wall 118A of the locking recess 116A of the first ferrite core 100A abuts against the inner wall 112B of the locking ridge 108B of the second ferrite core 100B, thereby preventing the first ferrite core 100A from moving relative to the second ferrite core 100B in the direction indicated by the arrow indicating lateral direction 3.

[0048] Second Embodiment Figure 3 shows a ferrite core assembly 20 according to the second embodiment.

[0049] Elements having the same reference numerals as those already described and illustrated in Figures 1 and 2 will not be described in detail again, and the above descriptions will be used for reference.

[0050] The ferrite core assembly 20 differs from the ferrite core assembly 10 in that the channels 226 and 228 of the ferrite core assembly 20 have hollow circular cross-sections, rather than hollow rectangular cross-sections, in a plane parallel to the front surface 12. Each channel 226 and 228 is defined between a first engagement surface 102A and a second engagement surface 102B. In particular, each ferrite core 100A and 100B includes two conductive grooves 204 and 206, respectively, extending along the extension direction 1 from the front surface 12 to the rear surface 14. In the second embodiment, the conductive grooves 204 and 206 are formed as semicircular grooves, respectively. Each channel 226, 228 has a diameter of 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 Figure 4, each conductor groove 204B, 206B is recessed into the second ferrite core 100B from the engaging surface 102B.

[0051] Channels 226 and 228 are configured to receive wires or cables with a circular cross-section. The volume of the hollow channels 26 and 28 according to the first embodiment may be smaller than the volume of the hollow channels 226 and 228 according to the second embodiment. Therefore, the overall size of the ferrite core assembly 10 can be made smaller than the overall size of the ferrite core assembly 20, which is advantageous.

[0052] Third Embodiment Figure 5 shows a ferrite core assembly 30 according to the third embodiment.

[0053] Elements having the same reference numerals as those already described and illustrated in Figures 1 and 2 will not be described in detail again, and the above descriptions will be used for reference.

[0054] According to the present invention, the ferrite core assembly 30 comprises a first ferrite core 300A and a second ferrite core 300B. The first ferrite core 300A includes a first engagement surface 302A. The second ferrite core 300B includes a second engagement surface 302B. In the ferrite core assembly 30, as shown in Figure 5, the first ferrite core 300A is positioned on the second ferrite core 300B according to the mounting direction 2 such that the first engagement surface 302A faces the second engagement surface 302B.

[0055] 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 and 300B are identical, only one ferrite core 300B is shown in Figure 6. The description of the second ferrite core 300B shown in Figure 6 applies equally to the first ferrite core 300A.

[0056] The ferrite core assembly 30 comprises two separate channels 26, 28. The channels 26, 28 are defined between a first engagement surface 302A and a second engagement surface 302B. Each channel 26, 28 has a rectangular cross-section in a plane parallel to the front surface 12, i.e., the (XY) plane. On the front surface 12 or the rear surface 14, each channel 26, 28 is chamfered inward toward the rear surface 14 or the front surface 12. This prevents sharp edges that could rub against or damage the electrical terminals during insertion into the ferrite core assembly. Each channel 26, 28 is dimensioned to receive electrical terminals. In particular, the channels 26, 28 are configured to receive electrical terminals with a rectangular cross-section.

[0057] 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 described in relation to the first embodiment, the transverse direction 3 is perpendicular to the extending direction 1 and the mounting direction 2, respectively. The transverse direction 3 is parallel to the X-axis of the Cartesian coordinate system shown in Figure 5.

[0058] In the third embodiment, the first ferrite core 300A and the second ferrite core 300B each comprise two locking ridges 304 and 306, respectively. Thus, the first ferrite core 300A comprises a first locking ridge 304A and a second locking ridge 306A. Similarly, the second ferrite core 300B comprises a first locking ridge 304B and a second locking ridge 306B. Each locking ridge 304A, 306A, 304B, and 304B has a solid rectangular cross-section in a plane parallel to the front surface 12.

[0059] Each first locking ridge 304A, 304B protrudes perpendicularly from its respective engagement surfaces 302A, 302B and extends longitudinally along the extension direction 1, particularly from the front surface 12 to the rear surface 14. As better shown in Figure 6, the first locking ridge 304B of the second ferrite core 300B has one outer wall 308B that is coplanar with the side surface 18. In other words, the outer wall 308B is formed as an extension of the side surface 18. The first locking ridge 304B includes one inner wall 310B on the opposite side of the outer wall 308B. Both side walls 308B, 310B extend in the (YZ) plane. The first locking ridge 304B includes a top surface 312B. The top surface 312B connects the outer wall 308B to the inner wall 310B. The top surface 312B extends in the (XZ) plane. The same explanation applies to the first locking ridge 304A of the first ferrite core 300A.

[0060] Each second locking ridge 306A, 306B protrudes perpendicularly from its respective engagement surfaces 302A, 302B and extends longitudinally along the extending direction 1, particularly from the front surface 12 to the rear surface 14. With respect to the second ferrite core 300B, as better shown in Figure 6, the second locking ridge 306B of the second ferrite core 300B is positioned equidistant from the side surface 22 and the inner wall 310B of the first locking ridge 304B. The second locking ridge 306B extends parallel to the first ridge 304B along the extending direction 1. The second locking ridge 306B includes two opposite 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 and 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.

[0061] In the examples shown in Figures 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 wall 308B and the inner wall 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 and 316B. The same explanation applies to the first ferrite core 100A.

[0062] In a modified form of the third embodiment (not shown), the widths 320A and 320B of the first locking ridges 304A and 304B are different from the widths 322A and 322B of the second locking ridges 306A and 306B.

[0063] 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 allow the upper surfaces 312B of the first locking ridge 304B and 318B of the second locking ridge 306B to make surface contact with the first engagement surface 302A, respectively. Similarly, the upper surfaces 312A of the first locking ridge 304A and 318A of the second locking ridge 306A make surface contact with the second engagement surface 302B, respectively.

[0064] Heights 324B and 326B define the heights of rectangular channels 26 and 328, respectively. The length 328 of rectangular channel 26 is defined along the X-axis between the inner wall 310A of the first locking ridge 304A and the side wall 316B of the second locking ridge 306B. The length 330 of rectangular channel 28 is defined along the X-axis between the side wall 316A of the second locking ridge 306A and the inner wall 310B of the first locking ridge 304B. Length 328 is equal to length 330. Lengths 328 and 330 are greater than widths 324A, 324B, 326A, and 326B, respectively. Lengths 328 and 330 are parallel to the X-axis of the Cartesian coordinate system shown in Figure 5, and widths 324A, 324B, 326A, and 326B are parallel to the Y-axis of the same coordinate system.

[0065] 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 abuts against the side portion 314B of the second locking ridge 306B of the second ferrite core 300B along the lateral direction 3. The side wall 314A and the side wall 314B are in surface contact from the front surface 12 to the rear surface 14.

[0066] In the third embodiment, displacement of the first ferrite core 300A relative to the second ferrite core 300B in the direction indicated by the arrow indicating lateral direction 3 is prevented. In particular, the side wall 314A of the second locking ridge 306A of the first ferrite core 300A abuts against the side portion 314B of the second locking ridge 306B of the second ferrite core 300B, thereby preventing the first ferrite core 100A from moving relative to the second ferrite core 100B in the direction indicated by the arrow indicating lateral direction 3.

[0067] Fourth Embodiment Figure 7 shows a ferrite core assembly 40 according to the fourth embodiment.

[0068] Elements having the same reference numerals as those already described and illustrated in Figures 1 and 2 will not be described in detail again, and the above descriptions will be used for reference.

[0069] According to the present invention, the ferrite core assembly 40 comprises a first ferrite core 400A and a second ferrite core 400B. The first ferrite core 400A includes a first engagement surface 402A. The second ferrite core 400B includes a second engagement surface 402B. In the ferrite core assembly 40, as shown in Figure 7, the first ferrite core 400A is positioned on the second ferrite core 400B according to the mounting direction 2 such that the first engagement surface 402A faces the second engagement surface 402B.

[0070] 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 and 400B are identical, only one ferrite core 400B is shown in Figure 8. The description of the second ferrite core 400B shown in Figure 8 applies equally to the first ferrite core 400A.

[0071] The ferrite core assembly 40 comprises two separate channels 26, 28. The channels 26, 28 are defined between a first engagement surface 402A and a second engagement surface 402B. Each channel 26, 28 has a rectangular cross-section in a plane parallel to the front surface 12, i.e., the (XY) plane. On the front surface 12 or the rear surface 14, each channel 26, 28 is chamfered inward toward the rear surface 14 or the front surface 12. This prevents sharp edges that could rub against or damage the electrical terminals during insertion into the ferrite core assembly. Each channel 26, 28 is dimensioned to receive electrical terminals. In particular, the channels 26, 28 are configured to receive electrical terminals with a rectangular cross-section.

[0072] 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 both opposite directions along the transverse direction 3. One direction along the transverse direction 3 is indicated by the arrow shown by reference numeral (3). The opposite direction along the transverse direction 3 is indicated by the arrow shown by reference numeral (-3). Directions (3) and (-3) along the transverse direction 3 are parallel to each other but opposite. 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 Cartesian coordinate system shown in Figures 7 and 8.

[0073] In the fourth embodiment, similar to the third embodiment, the first ferrite core 400A and the second ferrite core 400B each include two locking ridges 404 and 406, respectively.

[0074] Therefore, the first ferrite core 400A comprises a first locking ridge 404A and a second locking ridge 406A. Similarly, the second ferrite core 400B comprises a first locking ridge 404B and a second locking ridge 406B. Each locking ridge 404A, 406A, 404B, and 406B has a solid rectangular cross-section in a plane parallel to the front surface 12.

[0075] Each first locking ridge 404A, 404B protrudes perpendicularly (i.e., along the Y-axis) from its respective engagement surfaces 402A, 402B, and extends longitudinally along the extension direction 1 (i.e., along the X-axis), particularly from the front surface 12 to the rear surface 14.

[0076] With respect to the second ferrite core 400B, as better shown in Figure 8, the first locking ridge 404B of the second ferrite core 400B has one outer wall 408B that is coplanar with the side surface 22. In other words, the outer wall 408B is formed as an extension of the side surface 22. The first locking ridge 404B includes one inner wall 410B on the opposite side of the outer wall 408B. Both side walls 408B and 410B extend in the (YZ) plane. The first locking ridge 404B includes a top surface 412B. The top surface 412B connects the outer wall 408B to the inner wall 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.

[0077] Each second locking ridge 406A, 406B protrudes perpendicularly from its respective engagement surface 402A, 402B and extends longitudinally along the extension direction 1, particularly from the front surface 12 to the rear surface 14.

[0078] With respect to the second ferrite core 400B, as better illustrated in Figure 8, the second locking ridge 406B of the second ferrite core 400B is positioned equidistant from the side 18 and inner wall 410B of the first locking ridge 404B. The second locking ridge 406B extends parallel to the first ridge 404B along the extending direction 1 (i.e., along the Z-axis). The second locking ridge 406B includes two opposite side walls 414B, 416B. Both side walls 414B, 416B extend in the (YZ) plane. The second locking ridge 406B includes a top surface 418B. The top surface 418B connects the two side walls 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.

[0079] The width 420B of the first locking ridge 404B is defined along the X-axis between the outer wall 408B and the inner wall 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 and 416B. In the example shown in Figure 8, the width 420B of the first locking ridge 404B corresponds to the width 422B of the second locking ridge 406B. The same explanation applies to the first ferrite core 400A.

[0080] In a modified third embodiment (not shown), the widths 420A and 420B of the first locking ridges 404A and 404B may differ from the widths 422A and 422B of the second locking ridges 406A and 406B.

[0081] The height 424B of the first locking ridge 404B corresponds to the height 426B of the second locking ridge 406B. The same explanation applies to the first ferrite core 400A.

[0082] In the fourth embodiment, unlike the embodiments described above, the first ferrite core 400A and the second ferrite core 400B further comprise two locking recesses 428 and 430, respectively.

[0083] With respect to the second ferrite core 400B, as shown in Figure 8, the first locking recess 428B deepens perpendicularly from the engaging 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 Figure 8, which corresponds to the distance along the Y-axis between the engaging surface 402B and the bottom surface 434B of the first locking recess 428B. Similarly, the second locking recess 430B deepens perpendicularly from the second engaging 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 Figure 8, which corresponds to the distance along the Y-axis between the second engagement surface 402B and the bottom surface 436B of the second locking recess 430B. 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.

[0084] The first locking recess 428B has a width 438B. The width 438B is defined along the X-axis between the second engagement 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 engagement surface 402B and the side surface 18.

[0085] The portion of the second engagement surface 402 located between the first locking ridge 404B and the first locking recess 428B has the width indicated by reference numeral 442B in Figure 8. Width 442B is defined along the X-axis between the inner wall 410B and the first locking recess 428B. The portion of the second engagement surface 402 located between the second locking ridge 406B and the side surface 18 has the width indicated by reference numeral 444B in Figure 8. Width 444B is defined along the X-axis between the side wall 414B and the second locking recess 430B. Widths 442A, 422B, 444A, and 444B (collectively referred to as 442 and 444) have the same value.

[0086] Widths 442 and 444 correspond to the widths of rectangular channels 26 and 28. Heights 424 and 426 of locking ridges 404 and 406 correspond to the lengths of rectangular channels 26 and 28. Heights 424 and 426 are greater than widths 442 and 444.

[0087] In the fourth embodiment, the entire length of the two rectangular channels 428, 430 is arranged parallel to each other and parallel to the mounting direction 2 (i.e., the Y-axis). Thus, the orientation of the rectangular channels 26, 28 in the fourth embodiment differs from that of the first and third embodiments in that the width, rather than the length, of the two rectangular channels is arranged parallel to each other and parallel to the mounting direction 2 (i.e., the Y-axis). The orientation in the fourth embodiment allows for a smaller ferrite core assembly 40.

[0088] 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 abuts against the second engagement surface 402B along the opposite direction (-3) of the transverse direction 3. In particular, the inner wall 410A of the first locking ridge 404A of the first ferrite core 400A abuts against the surface of the second engagement surface 402B at height 434B along the opposite 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 abuts against the first engagement surface 402A along the direction (3) of the transverse direction 3. In particular, the inner wall 410B of the first locking ridge 404B of the second ferrite core 400B abuts against the surface of the first engagement surface 402A at a height of 434A along the lateral direction (3).

[0089] The width 422A of the second locking ridge 406A of the first ferrite core 400A is the same as the width 438B of the first locking recess 428B of the second ferrite core 400B. In particular, these widths 422A and 438B are adapted 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-fitting 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 interlocked in the first locking recess 428B of the second ferrite core 400B. A shape-fitting connection is formed between the second locking ridge 406A of the first ferrite core 400A and the first locking recess 428B of the second ferrite core 400B in both opposite directions (3) and (-3) along the transverse direction 3. 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 abuts against the surface of the second engagement surface 402B at a height of 428A along the opposite direction (-3) of the transverse direction 3.

[0090] 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 interlocked with the first locking recess 428A of the first ferrite core 400A. A shape-fitting connection is formed between the second locking ridge 406B of the second ferrite core 400B and the first locking recess 428A of the first ferrite core 400A in both opposite directions (3) and (-3) along the transverse direction 3. The side wall 416B of the second locking ridge 406B of the second ferrite core 400B abuts against the side wall 416A of the second locking ridge 406A of the first ferrite core 400A along the opposite direction (-3) of the transverse direction 3. The side wall 414B of the second locking ridge 406B of the second ferrite core 400B abuts against the surface of the first engagement surface 402A at a height of 428B along the direction (3) of the lateral direction 3.

[0091] Fifth Embodiment Figure 9 shows a ferrite core assembly 50 according to the fifth embodiment.

[0092] Elements having the same reference numerals as those already described and illustrated in Figures 1 and 2 will not be described in detail again, and the above descriptions will be used for reference.

[0093] According to the present invention, the ferrite core assembly 50 comprises a first ferrite core 500A and a second ferrite core 500B. The first ferrite core 500A includes a first engagement surface 502A. The second ferrite core 500B includes a second engagement surface 502B. In the ferrite core assembly 60, as shown in Figure 9, the first ferrite core 500A is positioned on the second ferrite core 500B according to the mounting direction 2 such that the first engagement surface 502A faces the second engagement surface 502B.

[0094] Unlike the embodiments described above, in the fifth embodiment, the first ferrite core 500A has a shape that is complementary to but different from that of the second ferrite core 500B. The exploded view in Figure 10 shows both the first ferrite core 500A and the second ferrite core 500B. Figures 9 and 10 are referenced below.

[0095] The ferrite core assembly 50 comprises two separate channels 26, 28. Each channel 26, 28 has a rectangular cross-section in a plane parallel to the front surface 12, i.e., the (XY) plane. At the front surface 12 or rear surface 14, each channel 26, 28 is at least partially chamfered inward toward the rear surface 14 or front surface 12. This prevents sharp edges that could rub against or damage the electrical terminals during insertion into the ferrite core assembly. Each channel 26, 28 is dimensioned to receive electrical terminals. In particular, the channels 26, 28 are configured to receive electrical terminals with a rectangular cross-section.

[0096] In the fifth embodiment, similar to 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 both opposite directions along the transverse direction 3. One direction along the transverse direction 3 is indicated by the arrow shown by reference numeral (3). The opposite direction along the transverse direction 3 is indicated by the arrow shown by reference numeral (-3). Directions (3) and (-3) along the transverse direction 3 are parallel to each other but opposite. The transverse direction 3 is perpendicular to the extending direction 1 and the mounting direction 2, respectively. The transverse direction 3 is parallel to the X-axis of the Cartesian coordinate system shown in Figures 9 and 10.

[0097] The first ferrite core 500A includes two locking recesses 504A and 506A. In the examples shown in Figures 9 and 10, the two locking recesses 504A and 506A have the same shape and dimensions. Therefore, the following structural description of one of the locking recesses 504A and 506A applies to the other.

[0098] The locking recesses 504A and 506A deepen perpendicularly from the engaging surface 502A (i.e., along the Y-axis) and extend longitudinally along the extension direction 1 (i.e., along the Z-axis). The locking recesses 504A and 506A each have a depth indicated by reference numeral 508A. For the first locking recess 504A, the depth 508A is defined along the Y-axis between the engaging surface 502A and the bottom surface 510A of the first locking recess 504A. For the first locking recess 506A, the depth 508A is defined along the Y-axis between the engaging surface 502A and the bottom surface 512A of the second locking recess 506A.

[0099] The first locking recess 504A includes two opposing walls 514A and 516A. The two opposing walls 514A and 516A extend in 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 514 and 516A are separated by a certain distance along the X-axis, which defines the width 518A of the first locking recess 504A.

[0100] The second locking recess 506A includes two opposing walls 520A and 522A. The two opposing walls 520A and 522A extend in 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 and 522A are separated by a certain 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.

[0101] The second ferrite core 500B comprises two locking ridges 524B and 526B. In the examples shown in Figures 9 and 10, the two locking ridges 524B and 526B have the same shape and dimensions. Therefore, the following structural description of one of the locking ridges 524B and 526B applies to the other.

[0102] Each locking ridge 524B, 526B has a solid rectangular cross-section in a plane parallel to the front surface 12. Each locking ridge 524B, 526B protrudes perpendicularly (i.e., along the Y-axis) from the second engagement surface 402B and extends longitudinally along the extending direction 1 (i.e., along the X-axis), particularly from the front surface 12 to the rear surface 14.

[0103] The first locking ridge 524B includes two opposing walls 527B and 528B. The two opposing walls 527B and 528B extend in their 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 and 528B are separated by a certain 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 and 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 engagement surface 502B and the upper surface 532B of the first locking ridge 524B.

[0104] The second locking ridge 526B includes two opposing walls 536B and 538B. The two opposing walls 536B and 538B extend in their 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 located opposite the first wall 536B. The two opposing walls 536B and 538B are separated by a certain 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 a top surface 540B. The top surface 540B connects the two opposing walls 536B and 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 a height 534B, similar to the height 534B of the first locking ridge 524B.

[0105] In the fifth embodiment, the rectangular channel 26 is defined between the first locking recess 504A of the first ferrite core 500A and the upper 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 upper surface 532B of the first locking ridge 524B of the second ferrite core 500B, a second surface defined by the bottom 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 upper 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 upper surface 540B of the second locking ridge 526B of the second ferrite core 500B, a second surface defined by the bottom 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.

[0106] The depths 508A of the locking recesses 504A and 506A are greater than the heights 543B of the locking ridges 524B and 526B. In particular, the difference between the depths 508A of the locking recesses 504A and 506A and the heights 543B of the locking ridges 524B and 526B forms a gap that allows for the insertion of electrical terminals into the respective channels 26 and 28.

[0107] In the fifth embodiment, the locking recesses 504A, 506A and locking ridges 524B, 526B are arranged in the ferrite core assembly 50 shown in Figure 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 is slightly larger than the width 530B of the locking ridges 524B, 526B, which allows the locking ridges 524B, 526B to be accommodated in their respective locking recesses 504A, 506A.

[0108] Therefore, in the fourth embodiment, the first locking ridge 524B of the second ferrite core 500B is partially received and interlocked in the first locking recess 504A of the first ferrite core 500A. A first shape-fitting 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 and interlocked in the second locking recess 506A of the first ferrite core 500A. A second shape-fitting 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.

[0109] The wall 514A of the first locking recess 504A of the first ferrite core 500A abuts against the wall 516B of the first locking ridge 524B of the second ferrite core 500B along the direction (3) of the lateral direction 3.

[0110] The wall 516A of the first locking recess 504A of the first ferrite core 500A abuts against the wall 528B of the first locking ridge 524B of the second ferrite core 500B along the opposite direction (-3) of the lateral direction 3.

[0111] The wall 522A of the second locking recess 506A of the first ferrite core 500A abuts against the wall 538B of the second locking ridge 526B of the second ferrite core 500B along the lateral direction 3 (3).

[0112] The wall 520A of the second locking recess 506A of the first ferrite core 500A abuts against the wall 536B of the second locking ridge 526B of the second ferrite core 500B along the opposite direction (-3) of the lateral direction 3.

[0113] Therefore, in the fifth embodiment, the first engaging surface 502A having locking recesses 504A and 506A, and the second engaging surface 502B having locking ridges 524B and 526B, provide mutual contact between the first ferrite core 500A and the second ferrite core 500B in both opposite directions (3) and (-3) along the transverse direction 3.

[0114] Sixth Embodiment Figure 11 shows a ferrite core assembly 60 according to the sixth embodiment.

[0115] Elements having the same reference numerals as those already described and illustrated in Figures 1 and 2 will not be described in detail again, and the above descriptions will be used for reference.

[0116] According to the present invention, the ferrite core assembly 60 comprises a first ferrite core 600A and a second ferrite core 600B. The first ferrite core 600A includes a first engagement surface 602A. The second ferrite core 600B includes a second engagement surface 602B. In the ferrite core assembly 60, the first ferrite core 600A is positioned on the second ferrite core 600B according to the mounting direction 2 such that the first engagement surface 602A faces the second engagement surface 602B.

[0117] 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 and 600B applies equally to the other ferrite core 600A and 600B.

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

[0119] The second ferrite core 600B includes a first side locking ridge 604B and a second side locking ridge 606B. The first side locking ridge 604B and the second side locking ridge 606B extend only partially along the extension direction 1 (i.e., the X-axis) from the front surface 12 toward the rear surface 14. Both the first side locking ridge 604B and the second side locking ridge 606B are coplanar with the front surface 12 and the sides 18, 22, but not with the rear surface 14.

[0120] In the first ferrite core 600A, the first lateral locking ridge 604A includes two side walls 610A and 612A. The outer wall 610A is coplanar with the side surface 22. The inner wall 612A is opposite the outer wall 610A. The side walls 610A and 612A extend in the (YZ) plane. The first lateral locking ridge 604A includes a top surface 614A. The top surface 614A connects the two side walls 610A and 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 wall 612A and the outer wall 610A. The same description applies to the second ferrite core 600B, with the above reference numerals replaced by the Latin letter "B".

[0121] In the first ferrite core 600A, the second side locking ridge 606A includes two side walls 616A and 618A. The outer wall 616A is coplanar with the side surface 18. The inner wall 618A is on the opposite side of the outer wall 616A. The side walls 616A and 618A extend in the (YZ) plane. The second side locking ridge 606A includes a top surface 620A. The top surface 620A connects the two side walls 616A and 618A. The top surface 620A extends in the (XZ) plane. The top surface 620A has a width 608A. In the examples in Figures 11 and 12, the width 608A of the first side locking ridge 604A is the same as the width (608A) of the second side locking ridge 606A. The same explanation applies to the second ferrite core 600B, by replacing the reference symbol above with the Latin letter "B".

[0122] The width 608A of the side locking ridges 604A and 606A is the same as the width 608B of the side locking ridges 604B and 606B.

[0123] The first ferrite core 600A further includes a central locking ridge 622A. The central locking ridge 622A extends only partially along the extending direction 1 (i.e., the X-axis) from the rear surface 14 toward the front surface 12. The central locking ridge 622A extends along the extending direction 1 (i.e., the X-axis) toward the front surface 12 until two side 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 has 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 of 630A. In the examples in Figures 11 and 12, the width 630A of the central locking ridge 622A is the same as the width 608A of the side locking ridges 604A and 606A. The front surface of the central locking ridge 622A corresponds to the rear surface 14 of the ferrite core assembly 60. The rear surface 632A of the central locking ridge 622A is on the opposite side of the rear surface 14. The rear surface 632A extends in the (XY) plane.

[0124] Similarly, the second ferrite core 600B includes a central locking ridge 622B. The central locking ridge 622B extends only partially along the extending direction 1 (i.e., the X-axis) from the front surface 12 toward the rear surface 14. The central locking ridge 622B extends along the extending direction 1 (i.e., the X-axis) toward the rear surface 14 until the two side locking ridges 604B, 606B begin. The central locking ridge 622A includes two side walls 624B, 626B. The side walls 624B, 626B extend in the (YZ) plane. The central locking ridge 622B has 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 in Figures 11 and 12, the width 630B of the central locking ridge 622B is the same as the width 608A of the side locking ridges 604B and 606B. The front of the central locking ridge 622B corresponds to the front surface 12 of the ferrite core assembly 60. The rear surface 632B of the central locking ridge 622B is on the opposite side of the front surface 12. The rear surface 632B extends in the (XY) plane.

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

[0126] The first ferrite core 600B similarly comprises two side locking recesses 634B, 636B and one central locking recess 638B. The two side locking recesses 634B, 636B each extend only partially along the extending direction 1 (i.e., the X-axis) from the front surface 12 toward the rear surface 14. The central locking recess 638B extends only partially along the extending direction 1 (i.e., the X-axis) from the rear surface 14 toward the front surface 12. More specifically, the first side locking recess 634B extends along the extending direction 1 (i.e., the X-axis) until the first side locking ridge 604B begins. The second side locking recess 636B extends along the extending direction 1 (i.e., the X-axis) until the second side locking ridge 604A begins. The central side locking recess 638B extends along the extending direction 1 (i.e., the X-axis) until the central locking ridge 622B begins. The central locking recess 638B opens to the rear surface 14. The first side locking recess 634B opens to the front surface 12 and the side surface 22. The second side locking recess 636B opens to the front surface 12 and the side surface 18. The width (608B) of the first side 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 side locking recess 636B of the second ferrite core 600B corresponds to the width 608A of the second locking ridge 606B 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.

[0127] The rectangular channel 26 is defined between the first engagement surface 602A, the second engagement surface 602B, the inner wall 612A, and the side wall 626B. The rectangular channel 28 is defined between the first engagement surface 602A, the second engagement surface 602B, the inner wall 618A, and the side wall 624B. The maximum dimensions of each rectangular channel 26 extend along the mounting direction 2, i.e., in the same direction as the locking ridges 604A, 606B, 622A, 604B, 606B, and 622B.

[0128] In the sixth embodiment, the first engagement surface 602A and the second engagement surface 602B thereby provide mutual contact between the first ferrite core 600A and the second ferrite core 600B in both opposite directions along the transverse direction 3. One direction along the transverse direction 3 is indicated by the arrow shown by reference numeral (3). The opposite direction along the transverse direction 3 is indicated by the arrow shown by reference numeral (-3). Directions (3) and (-3) along the transverse direction 3 are parallel to each other but opposite. The transverse direction 3 is perpendicular to the extending direction 1 and the mounting direction 2, respectively. The transverse direction 3 is parallel to the X-axis of the Cartesian coordinate system shown in Figure 11.

[0129] In the ferrite core assembly 60, the central locking ridge 622A is received and interlocked in the central locking recess 638B. This interlocking arrangement provides a shape-fitting 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 prevented in both opposite directions (3) and (-3) along the lateral direction 3.

[0130] Similarly, as shown in Figure 11, the central locking ridge 622B is received and interlocked in the central locking recess 638A. This interlocking arrangement provides a shape-fitting 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 prevented in both opposite directions (3) and (-3) along the lateral direction 3.

[0131] The first side locking ridge 604A is received in the first side recess 634B. Displacement of the first ferrite core 600A relative to the second ferrite core 600B is prevented in particular in the direction (3) along the transverse direction 3 by the inner wall 612A abutting against the first side recess 634B. The second side locking ridge 606A is received in the second side recess 636B. Displacement of the first ferrite core 600A relative to the second ferrite core 600B is prevented in particular in the direction (-3) along the transverse direction 3 by the inner wall 618A abutting against the second side recess 636B.

[0132] Similarly, the first side locking ridge 604B is received in the first side recess 634A. Displacement of the first ferrite core 600A relative to the second ferrite core 600B is prevented in particular in the direction (3) along the transverse direction 3 by the inner wall 612A abutting against the first side recess 634A. The second side locking ridge 606B is received in the second side recess 636B. Displacement of the first ferrite core 600A relative to the second ferrite core 600B is prevented in particular in the direction (-3) along the transverse direction 3 by the inner wall 618B abutting against the second side recess 636B.

[0133] In the sixth embodiment, the first engagement surface 602A and the second engagement surface 602B thereby further provide mutual contact between the first ferrite core 600A and the second ferrite core 600B in both opposite directions along the extending direction 1. One direction along the transverse direction 1 is indicated by the arrow shown by reference numeral (1). The opposite direction along the transverse direction 1 is indicated by the arrow shown by reference numeral (-1). Directions (1) and (-1) along the extending direction 1 are parallel to each other but opposite. The extending direction 1 is perpendicular to the mounting direction 2 and the transverse direction 3, respectively. The extending direction 1 is parallel to the Z-axis of the Cartesian coordinate system shown in Figure 11.

[0134] The first locking ridge 604A and the first locking ridge 604B abut each other along the extending direction 1, the second locking ridge 606A and the second locking ridge 606B abut each other along the extending direction 1, and the central locking ridge 622A and the central locking ridge 622A abut each other along the extending direction 1, thereby preventing the displacement of the first ferrite core 600A relative to the second ferrite core 600B in both directions (1) and (-1) along the extending direction 1.

[0135] Each ferrite core assembly 10, 20, 30, 40, 50, and 60 is designed for electrical connectors, particularly for pyrotechnic devices, which are plugged into mating connectors in safety restraint systems.

[0136] Assembly method Figures 13A to 13D show a sequence of steps in 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 shown in Figures 13A to 13D is applicable to any of the above-described embodiments of a ferrite core assembly.

[0137] As shown in Figure 13A, the electrical connector 700 may be a pyrotechnic connector, also known as a squid-type connector. The electrical connector 700 is configured to be plugged into a mating connector (not shown), in particular a mating connector used in a safety restraint system, along the mounting direction 2.

[0138] The electrical connector 700 comprises a housing 702. The housing 702 includes a first receptacle 704 for housing 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 comprises a mating portion 712 configured to mate with a corresponding mating connector (not shown).

[0139] In step (A) of the assembly method shown in Figure 13A, the first ferrite core 500A is assembled perpendicular to the electrical connector 700. More precisely, the first ferrite core 500A is inserted into the first receptacle 704 along the mounting direction 2.

[0140] As shown in step (B) of the assembly method in Figure 13B, the side 16 of the first ferrite core 500A is located on the bottom surface of the receptacle 704. In step (B) of the assembly method, the two electrical terminals 708 are assembled perpendicular to the electrical connector 700. More precisely, 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 and 506B help to guide the alignment of the respective rectangular portions 714 of the electrical connector 708 on the first ferrite core 500A.

[0141] During step (C) of the assembly method shown in Figure 13C, the second ferrite core 500B is inserted perpendicularly to the electrical connector 700 and assembled. 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 positioned on the first ferrite core 500A. The first ferrite core 500A is then assembled with the second ferrite core 500B to form the ferrite core assembly 50.

[0142] In the ferrite core assembly 50 shown in step (D) of the assembly method shown in Figure 13D, the first engagement surface 502A is in surface contact with the second engagement surface 502B. The electrical terminals 708 are received between the channels 26, 28 formed between the locking recesses 504A, 506B of the first ferrite core 500A and the locking ridges 524B, 526B of the second ferrite core 500B.

[0143] In step (D) of the assembly method, the wire fastener 710 is assembled perpendicular to the electrical connector 700. More precisely, the wire fastener 710 is inserted into the second receptacle 706 along the mounting direction 2.

[0144] This assembly method allows different parts to be assembled in a single direction, i.e., along mounting direction 2, enabling a vertical assembly process. This method simplifies the assembly process. [Explanation of symbols]
