[0002] This application claims the benefit of Korean Patent Application No. 10-2024-0082854, filed on June 25, 2024, and Korean Patent Application No. 10-2025-0063003, filed on May 15, 2025, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] The following disclosure relates to an entry component. Background Technology

[0004] Generally speaking, electric vehicles require higher voltage and / or greater current than conventional vehicles. Therefore, electric vehicles are equipped with charging inlet devices to efficiently charge the vehicle by receiving external power.

[0005] Electric vehicles are vehicles that use energy stored in batteries as their power source, and these batteries discharge after a certain period of use. When the battery is discharged, the vehicle cannot move; therefore, batteries are typically configured to be recharged and reused before they discharge.

[0006] Therefore, an inlet for charging the vehicle's battery from an external power source is installed on the electric vehicle, and an outlet is formed that is fastened to the inlet and charges the electric vehicle.

[0007] In addition, the entry device requires a structure to protect electronic circuits sensitive to high voltage and / or high current from external electromagnetic interference (EMI).

[0008] The above description is information that the inventor obtained or had at the time of conceiving this disclosure, and is not necessarily technology known prior to the filing of this application. Utility Model Content

[0036] Figure 1 This is an illustration showing an entry component installed on a vehicle panel according to an embodiment. Figure 2 This is an exploded perspective view showing the entry component according to an embodiment.

[0037] refer to Figure 1 and Figure 2According to an embodiment, the inlet assembly 1 can be installed on a vehicle to receive power from outside the vehicle and transmit power to electronic components (e.g., a battery) provided inside the vehicle. Furthermore, during the power transmission through the inlet assembly 1, electromagnetic interference (EMI) can occur in nearby components, and this EMI can cause operational errors in electronic components, such as by acting as noise on electronic components provided inside the vehicle. However, the inlet assembly 1 according to the embodiment can reduce this problem. The inlet assembly 1 may include an inlet housing 11, a power cable 12, an inner ring 13, an outer ring 14, a grounding clamp 15, a grounding cable 16, a connection terminal 17, a grounding cover 18, and a mounting housing 19. Hereinafter, an example will be provided with both the inner ring 13 and the outer ring 14. However, only one of the inner ring 13 and the outer ring 14 may be provided. For example, the inner ring 13 and the outer ring 14 may be collectively referred to as "rings".

[0038] The inlet housing 11 can be mounted on a mounting housing 19, which is mounted on a vehicle. The inlet housing 11 can be made of, for example, an insulating material (e.g., resin) to reduce the problem of current leakage from the power cable 12 to the outside. The inlet housing 11 may include: a housing body 111 that provides space for the power cable 12 to be inserted therein; and a housing cover 115 that includes an opening through which the power cable 12 can pass and shields one side of the inlet housing 11 (e.g., the inlet side where the power cable 12 is inserted into the inlet housing 11).

[0039] At least a portion of the power cable 12 may be housed within the inlet housing 11, and the power cable 12 may transmit power received from outside the vehicle to the vehicle's internal electronic components. At least a portion of the power cable 12 may be housed within the inlet housing 11. For example, the conductive wire 121 of the power cable 12 (see...) Figure 4 It can be butt-welded to the connection terminal 17. In this way, the reliability of power transmission can be improved by ensuring high connection strength.

[0040] For example, the power cable 12 may include a plurality of power cables 12a and 12b. The plurality of power cables 12a and 12b may include a first cable 12a that transmits charging current in the form of direct current (DC) and a second cable 12b that transmits charging current in the form of alternating current (AC). For example, at least one of the first cable 12a and the second cable 12b (e.g., the first cable 12a) may be formed with a shielded cable structure including a double insulating sheath and a shielding layer 123 of conductive material positioned between the double insulating sheaths (see [link to relevant documentation]). Figure 4Examples of shielded cable structures are described below. For instance, the first cable 12a may be configured as a shielded cable structure with a double insulating sheath as described above, while the second cable 12b may be configured as a general cable structure with a single insulating sheath.

[0041] For example, the conductive wires 121 of the first cable 12a and the conductive wires 121 of the second cable 12b can be butt-welded to the connecting terminal 17. For example, Figure 2 The conductive wires 121 of the interconnecting first cable 12a and the second cable 12b are shown. According to this structure, the power cables 12 can receive charging current in the form of DC or AC from outside the vehicle through the same connection terminal 17, and can charge the vehicle through either the first cable 12a or the second cable 12b. That is, since it is not necessary to form a connection terminal 17 for each of the multiple power cables 12a and 12b, the number of components and the overall volume of the inlet assembly 1 can be reduced, and manufacturing costs and time can be reduced. In this way, the number of manufacturing processes can be reduced while ensuring high connection strength, thereby saving manufacturing costs and time.

[0042] The inner ferrule 13 can contact the shielding layer 123 of the power cable 12 (see...). Figure 4 This forms a conductive path from the power cable 12 to the grounding clamp 15 to reduce EMI. (See reference) Figure 3 And an example of the inner ring 13 is described below.

[0043] The outer ring 14 can perform the function of surrounding the shielding layer 123 of the power cable 12 (see...) Figure 4 This function ensures that the shielding layer 123 does not detach from the inner ring 13. (See reference) Figure 3 And the following describes an example of the outer loop 14.

[0044] The grounding clamp 15 can be electrically connected to the shielding layer 123 in the power cable 12 provided in the inlet housing 11 (see...). Figure 3 The grounding clamp 15 may be formed of a conductive material (e.g., metal) and performs the function of transferring current leaking from the power cable 12 through the grounding cover 18 to the grounding cable 16. An example of the structure of the grounding clamp 15 is described below with reference to the accompanying drawings.

[0045] The grounding cable 16 can ground the current leaking from the power cable 12. One end of the grounding cable 16 can be fastened to a grounding clip 15 inserted into the grounding cover 18, and the other end of the grounding cable 16 can be electrically connected to a grounding structure, such as a vehicle panel P located outside the inlet housing 11. For example, one end of the grounding cable 16 can be connected to the grounding clip 15 through the housing cover 115, and the other end of the grounding cable 16 can be directly or indirectly connected to the vehicle panel P. For example, the other end of the grounding cable 16 can be indirectly connected to the vehicle panel P through a metal structure (e.g., a fastening structure such as an insert nut) that mounts the housing 19.

[0046] The connection terminal 17 can be connected to an external charging device connector and can transmit power to the power cable 12. For example, the connection terminal 17 may have a plate shape. For example, the connection terminal 17 may include a rigid conductive material and be provided in a plate shape (e.g., rectangular shape) with sufficient width so that the conductive wires 121 of the plurality of power cables 12a and 12b can contact each other. With this structure, the connection terminal 17 and the plurality of power cables 12a and 12b can be physically connected and / or electrically connected via butt welding as described above.

[0047] The grounding cover 18 may include a bidirectional insertion structure, with one side connected to the grounding clamp 15 and the other side connected to the grounding cable 16. The grounding cover 18 may be formed of an insulating material (e.g., resin) and may have a shape that surrounds at least a portion (e.g., a side surface) of the grounding clamp 15. This structure can reduce current leakage from the grounding clamp 15 to the grounding cable 16 to other components. An example of the structure of the grounding cover 18 is described below with reference to the accompanying drawings.

[0048] Mounting housing 19 can be fastened to inlet housing 11 and can support inlet housing 11 relative to vehicle panel P. For example, mounting housing 19 may include, but is not limited to, fastening bolts and / or hole structures through which fastening bolts can pass to vehicle panel P. For example, at least a portion of mounting housing 19 may be formed of a conductive material. With this structure, a grounding wire can be formed that can transmit current leaking from power cable 12 to vehicle panel P via grounding cable 16 and mounting housing 19.

[0049] Figure 3 A partial sectional perspective view is provided to show the power cable, inner ring, outer ring, grounding clamp, and grounding box mounted on the inlet housing according to an embodiment. Figure 4 and Figure 5 This is a cross-sectional view illustrating the process of installing the outer ring with the inner ring mounted on the power cable according to an embodiment.

[0050] refer to Figures 3 to 5According to an embodiment, the housing body 111 may include a body grounding hole 111a into which a grounding cable 16 may be inserted. For example, the housing body 111 may include a housing seal S mounted on a surface facing the housing cover 115 and configured to reduce foreign objects introduced from outside the vehicle. For example, it should be noted that the body grounding hole 111a may be formed in the housing seal S, such as... Figure 2 and Figure 3 As shown in the figure. According to an embodiment, the housing cover 115 may include a cover grounding hole 115a through which a grounding cable 16 may pass. Based on the body grounding hole 111a and the cover grounding hole 115a, the grounding cable 16 may be inserted into a bidirectional insertion structure 182 formed in the grounding cover 18. An example of the structure of the bidirectional insertion structure 182 is described below.

[0051] According to an embodiment, the power cable 12 may be configured with a shielded cable structure including double insulating sheaths 122 and 124 and a shielding layer 123 made of conductive material positioned between the double insulating sheaths 122 and 124. The power cable 12 may include a conductive wire 121 made of conductive material, an inner insulating layer 122 surrounding the conductive wire 121, an outer insulating layer 124 surrounding the inner insulating layer 122, and a shielding layer 123 for transmitting current leaked from the conductive wire 121 to the outside. For example, at least a portion of the shielding layer 123 may be surrounded by an inner ferrule 13, and at least a portion of the shielding layer 123 may be surrounded by an outer ferrule 14.

[0052] A portion of the inner ring 13 is in contact with the shielding layer 123, and the remainder of the inner ring 13 is in contact with the grounding clamp 15. The inner ring 13 may include: a first portion 131 that contacts the outer surface of the portion of the shielding layer 123 not surrounded by the outer insulation layer 124; a second portion 132 that contacts the grounding clamp 15; and a connecting portion 133 that connects the first portion 131 to the second portion 132.

[0053] The first part 131 can be positioned at the portion of the power cable 12 where the outer insulation layer 124 has been stripped. For example... Figure 4 As shown, the shielding layer 123 may be exposed in the portion where the outer insulation layer 124 is stripped. The first portion 131 may be mounted to surround at least a portion of the outer surface of the outwardly exposed portion of the shielding layer 123.

[0054] The second portion 132 may have a diameter larger than that of the first portion 131 and may surround the outermost peripheral surface of the power cable 12. The second portion 132 may be provided as a portion positioned close to the stripped portion to surround the outer insulation layer 124, thereby preventing the outer insulation layer 124 from separating from the power cable 12.

[0055] The connecting portion 133 may be a portion that interconnects a first portion 131 and a second portion 132 with different diameters, and may have, for example, a frustoconical shape. Through the connecting portion 133, current leaking into the first portion 131 can be transferred to the second portion 132. For example, the connecting portion 133 may reduce the flow of foreign matter between the outer insulating layer 124 and the shielding layer 123.

[0056] The shielding layer 123 may be formed of a conductive material and may have, for example, a mesh shape, but is not limited thereto. At least a portion of the shielding layer 123 may be positioned between the inner insulating layer 122 and the outer insulating layer 124. Figure 5 As shown, the remaining portion of the shielding layer 123 may extend from the end portion of at least a portion of the shielding layer 123 described above along... Figure 4 The arrow direction surrounds the first portion 131 of the inner ferrule 13 in a reverse folding manner. According to this structure, the shielding layer 123 can contact both the inner and outer surfaces of the first portion 131 of the inner ferrule 13, thereby effectively transferring the current leaking from the conductive wire 121 to the inner ferrule 13.

[0057] In this state, the outer ring 14 can be installed to surround the outer surface of the reverse folded portion of the shielding layer 123, such as Figure 5 As shown in the diagram. Using this structure, the shielding layer 123 and the inner ring 13 can maintain a stable contact with each other.

[0058] For example, current leaking from conductive wire 121 can be transmitted sequentially along shielding layer 123, inner ferrule 13 and grounding clamp 15, and as described below, current can be transmitted to the outside through grounding cable 16 connected to grounding clamp 15.

[0059] Figure 6 A cross-sectional view of the inlet housing according to an embodiment is shown. Figure 7 A perspective view illustrating the connection relationships between the grounding clamp, grounding box, and grounding wire according to an embodiment. Figure 8 This illustration shows the structure of a grounding clamp in a planar unfolded state according to an embodiment. Figure 9 for Figure 6 A magnified view of part A.

[0060] refer to Figures 6 to 9 According to an embodiment, the grounding clamp 15 may include: a clamp body 151 having a hole H through which a power cable 12 can pass; a contact protrusion 152 that protrudes toward the center of the hole H in the clamp body 151 and contacts an inner sleeve 13; a fixing tab 153 that protrudes from the clamp body 151 to the outside and can be fixed to a grounding cover 18; and a grounding tab 154 that extends from the clamp body 151 and is inserted into a bidirectional insertion structure 182.

[0061] According to an embodiment, the grounding clamp 15 can be formed by cutting and bending a metal plate, such as... Figure 8 As shown in the image. Figure 8 The metal plate shown is cut to form the grounding clamp 15, and can be bent into position as shown in the diagram. Figure 8 The metal plate shown in the figure is used to form a shape with the following characteristics. Figure 7 The grounding clamp 15 is shown in the diagram. Furthermore, unless otherwise stated, it should be noted that the grounding clamp 15 does not necessarily have to be formed by cutting and bending a single metal plate. For example, the grounding clamp 15 can be formed by connecting (e.g., welding) multiple metal plates. Figure 7 The shape shown in the image.

[0062] The clamp body 151 may include: a support plate 151a having a surface perpendicular to the direction through which the power cable 12 passes; and a side surface plate 151b arranged along the circumferential direction of the support plate 151a. For example, a hole H through which the power cable 12 can pass may be formed in the support plate 151a. For example, a fixing tab 153 and a grounding tab 154 may be formed in the side surface plate 151b.

[0063] The contact protrusion 152 may have a shape extending from the edge of the hole H toward the center of the hole H. For example, multiple contact protrusions 152 may be spaced apart along the edge of the hole H. For example, multiple contact protrusions 152 may be arranged radially based on the center of the hole H. For example, the contact protrusion 152 may have a shape that is bent to be inclined from the support plate 151a toward the cable hole 183 of the grounding cover 18. For example, the contact protrusion 152 may have a shape that is inclined toward the center of the hole H toward the housing cover 115. With the shapes described above, it is possible to help the grounding clamp 15 in such a way as Figure 2 In the state shown, it smoothly engages with the power cable 12. In the final assembled state, the contact protrusion 152 can contact the inner ferrule 13, as shown. Figure 9 As shown, this allows the current leaking from the power cable 12 to be transmitted to the outside through the inner ferrule 13, contact protrusion 152, clamp body 151, grounding tab 154 and grounding cable 16 in sequence.

[0064] The fixing tab 153 can be formed, for example, by a portion of the cutting clamp body 151. For example, the fixing tab 153 can be formed by cutting a portion of the side surface plate 151b and bending the cut portion so that the cut portion protrudes outward from the side surface plate 151b. The end portion of the fixing tab 153 faces in the opposite direction to the end portion of the grounding tab 154, thus improving the fastening force between the grounding clamp 15 and the grounding cover 18, and also improving the fastening force between the grounding tab 154 and the bidirectional insertion structure 182 of the grounding cover 18.

[0065] The grounding tab 154 can be fastened to the bidirectional insertion structure 182 of the grounding cover 18. The grounding tab 154 may have a shape extending from the side surface plate 151b toward the housing cover 115. For example, the grounding tab 154 may include a tab body 154a and a wing portion 154b disposed on at least one side of the tab body 154a. For example, at least one wing portion 154b may be flexible (see...). Figure 9 The grounding tab 154 is overlapped in the thickness direction of the tab body 154a. By using this structure, the stiffness of the grounding tab 154 is increased, which reduces the problem of damage to the grounding tab 154 during the process of fastening the grounding tab 154 to the bidirectional insertion structure 182 and / or the grounding cable 16.

[0066] According to an embodiment, the grounding cable 16 may include: a grounding wire 161 comprising a conductive material; a grounding socket 162 provided at one end of the grounding wire 161 and connected to a grounding tab 154; and a grounding side seal 165 for reducing the flow of foreign matter from the outside of the vehicle into the grounding wire 161.

[0067] The grounding socket 162 can be inserted into the bidirectional insertion structure 182 of the grounding cover 18. The grounding wire 161 can be connected to one end of the grounding socket 162, and a groove for receiving the grounding tab 154 can be formed at the other end of the grounding socket 162. A contact structure capable of resiliently contacting the grounding tab 154 can be formed at the other end of the grounding socket 162.

[0068] The grounding side seal 165 can seal between the grounding wire 161 and the main body grounding hole 111a. For example, when the main body grounding hole 111a is formed inside the housing seal S, the problem of foreign matter flowing into the bidirectional insertion structure 112 can be effectively reduced by the double sealing structure.

[0069] According to an embodiment, the grounding cover 18 may include a cover body 181, a bidirectional insertion structure 182, a cable hole 183, a clamping groove 184, and a caught portion 185. For example, the cover body 181 is the portion that forms the overall external shape of the grounding cover 18 and can support the bidirectional insertion structure 182.

[0070] The bidirectional insertion structure 182 may have a tab hole 1821 into which a grounding tab 154 is inserted and a socket groove 1822 into which a grounding socket 162 is inserted. For example, the tab hole 1821 and the socket groove 1822 may be positioned at both ends of the bidirectional insertion structure 182. For example, the longitudinal direction of the bidirectional insertion structure 182 may be parallel to the longitudinal direction of the power cable 12, but is not limited thereto. For example, the tab hole 1821 may be recessed toward the housing cover 115. For example, the socket groove 1822 may be recessed in the direction in which the power cable 12 is inserted into the inlet housing 11. The socket groove 1822 may communicate with the tab hole 1821. The grounding tab 154, inserted through the tab hole 1821, may be exposed in the socket groove 1822, such that the grounding tab 154 can be inserted into the grounding socket 162.

[0071] The cable hole 183 can be formed to penetrate the cover body 181. Through the cable hole 183, the power cable 12 can pass through the grounding cover 18.

[0072] The slot 184 is recessed in the direction in which the power cable 12 extends from the outer surface of the cover body 181 (e.g., toward the housing cover 115). The side surface plate 151b of the grounding clamp 15 can be inserted into the slot 184. With the shape described above, it is possible to reduce direct contact between the side surface plate 151b of the grounding clamp 15, which is made of conductive material, and other components.

[0073] The snap-fit ​​portion 185 is the part that snaps into the fixing tab 153 of the grounding clip 15, and may be formed on the side surface of the cover body 181. For example, the snap-fit ​​portion 185 may have a groove shape that is recessed outward from the inner wall of the cover body 181. For example, the end portion of the fixing tab 153 may be snapped into the snap-fit ​​portion 185, thereby improving the fastening force between the grounding clip 15 and the grounding cover 18.

[0074] Although embodiments have been described with reference to the limited accompanying drawings, various technical modifications and variations can be made thereon by those skilled in the art. For example, suitable results may be obtained by performing the described techniques in a different order, and / or by combining the components in the described system, architecture, apparatus, or circuit in a different manner, or by replacing or supplementing the components with other components or their equivalents.

[0075] Therefore, other implementations, embodiments, and / or equivalents of the claims are within the scope of the appended claims.
