[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority under 35 U.S.C. §119(a) to Korean Patent Application No. 10-2022-0187820, filed on December 28, 2022, which is incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a shielding module for a high voltage connector. Background Art

[0004] The waterproof controller is equipped with a separate pressure compensation element (PCE) after the housing is tightly sealed to maintain the same internal and external air pressure. That is, since the conventional controller requires a separately installed PCE, the housing needs to be redesigned according to the change of waterproof / non-waterproof specifications.

[0005] When the high voltage connector is mounted on the controller, a metal shield is formed around the high voltage terminal to reduce the noise impact of the high voltage terminal, and then the high voltage terminal is connected to the housing to form a ground. In particular, it is necessary to further manufacture a coupling structure, such as forming a protrusion on the housing, so that the housing and the shielding plate are grounded.

[0006] Thus, regardless of whether the specification is mass-produced or not, and whether the housing and connector need to be redesigned / manufactured, there is a problem that the unit cost of the product will increase significantly. Summary of the invention

[0007] The present disclosure relates to a shielding module for a high-voltage connector, in which a grounding structure of a housing of a controller and a high-voltage connector are separately modularized, and a film used as a pressure compensation element (PCE) is integrated instead of a conventional PCE, so that a new platform format is provided without incurring unnecessary costs compared to the prior art.

[0008] The technical problems to be solved by the present disclosure are not limited to the above-mentioned technical problems, and those skilled in the art can clearly understand other technical problems not mentioned above through the following description.

[0010] The slit may be in the shape of a long hole, and the film may have the shape of the slit.

[0011] The sealing member may be located in an assembly portion of the housing.

[0012] The sealing retainer may have a supporting step that supports a sealing member between the housing and the sealing retainer to prevent the sealing member in an assembled portion with the housing from blocking the film.

[0013] Preferably, the film is bi-injection moulded around the slit.

[0014] Preferably, the membrane is located in the ventilation line when the base plate is fixed to the high voltage connector.

[0015] The membrane may be used as a pressure compensating element (PCE) of the controller.

[0016] The substrate may be slidably mounted on the main body of the high voltage connector and then laser welded.

[0017] The base plate may include a protrusion member protruding along an outer peripheral surface to be slidably mounted on a body of the high voltage connector.

[0018] When the substrate is mounted on the main body of the high voltage connector and is laser-fused, the protrusion member may serve as a base material.

[0019] The entire portion of the substrate that contacts the high voltage connector may be laser-fused.

[0020] A vehicle may include a high voltage connector having the shielding module.

[0021] According to another embodiment, a shielding module for a high-voltage connector is provided, which may include: a substrate; a shielding terminal connected to the substrate and in grounding contact with an inner wall of the housing and a shielding plate of the high-voltage connector; and a sealing retainer protruding upward from the top of the substrate and having a film, wherein the film may be located in a ventilation line when the substrate is fixed to the high-voltage connector.

[0023] The base plate may include a protrusion member protruding along an outer peripheral surface to be slidably mounted on a body of the high voltage connector.

[0024] When the substrate is mounted on the main body of the high voltage connector and is laser-fused, the protrusion member may serve as a base material.

[0025] Preferably, the membrane is used as a replacement for a pressure compensating element (PCE) of the controller.

[0026] According to another embodiment, a shielding module for a high-voltage connector is provided, which may include: a substrate; a shielding terminal connected to the substrate and in ground contact with an inner wall of the housing and a shielding plate of the high-voltage connector; and a sealing retainer protruding upward from the top of the substrate and having a thin film, wherein the entire portion of the substrate in contact with the high-voltage connector can be laser melted.

[0027] The substrate may be fixed to the body of the high voltage connector by snap-fitting and then laser-fused.

[0028] The sealing holder may have a supporting step that supports a sealing member between the housing and the sealing holder.

[0029] The support step may protrude at both ends of the sealing holder in a front-rear direction relative to a center portion of the sealing holder.

[0030] According to the present disclosure, a grounding structure and a high voltage connector of a housing of a controller are separately modularized, and a thin film used as a PCE is integrated instead of a conventional PCE, thereby saving unnecessary costs compared to the related art.

[0043] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0044] Basic Configuration

[0045] Figure 1 is an exploded perspective view showing a controller having a shielding module for a high voltage connector according to an embodiment of the present disclosure, Figure 2 is a perspective view showing a shielding module for a high voltage connector according to an embodiment of the present disclosure.

[0046] The shielding module 100 for a high voltage connector employs a film serving as a pressure compensation element (PCE) for internal and external ventilation of the controller 1 formed as a waterproof type, thereby maintaining the same internal and external air pressure of the controller 1 without the PCE.

[0047] The shielding module 100 for a high voltage connector electrically connects a ground portion between the high voltage connector 30 and the housing 10 .

[0048] The shield module 100 for a high voltage connector includes a substrate 110 , a shield terminal 120 , and a sealing holder 130 .

[0049] The substrate 110 forms a base of the shielding module 100 for the high voltage connector. The substrate 110 can be slidably mounted to the high voltage connector 30 to be grounded between the housing 10 of the controller 1 and the high voltage connector 30. In this case, the substrate 110 is slidably mounted on the body of the high voltage connector 30 and then laser-fused and fixed in a corresponding position.

[0050] To this end, the substrate 110 includes a protrusion member 111 .

[0051] The protrusion member 111 protrudes along the outer peripheral surface of the substrate 110 , and when the substrate 110 is mounted on the body of the high voltage connector 30 and is laser-welded, the protrusion member 111 may serve as a base material.

[0052] Preferably, the entire portion of the substrate 110 that contacts the high voltage connector 30 is laser welded.

[0053] The shield terminal 120 is connected to the substrate 110. The shield terminal 120 is fastened to the substrate 110 at intervals. The upper end of the shield terminal 120 contacts the inner wall 13 of the housing 10, and the lower end of the shield terminal 120 contacts the shield plate 31 of the high voltage connector 30. Therefore, the shield terminal 120 is grounded between the housing 10 and the high voltage connector 30.

[0054] The sealing holder 130 protrudes upward from the top of the substrate 110 and has a thin film 131 in a slit in the form of a long hole.

[0055] The film 131 is formed by double injection molding around the slit to cover the slit. That is, the film 131 is formed in a form corresponding to the shape of the slit.

[0056] Preferably, when the base plate 110 is fixed to the high voltage connector 30 , the film 131 is located on the ventilation line.

[0057] The film 131 serves as a PCE of the controller 1. In other words, the PCE is necessary to maintain the same internal and external air pressures of the controller 1 formed as a waterproof type, but in the present disclosure, the film 131 is employed to allow the controller 1 to maintain the same internal and external air pressures without the PCE.

[0058] The sealing holder 130 may further include a support step 132 that supports the sealing member ( Figure 8 32 in the figure).

[0059] Fastening structure

[0060] Figures 3 to 6 A process of installing a shielding module for a high-voltage connector in a high-voltage connector according to an embodiment of the present disclosure is shown.

[0061] The substrate 110 of the shielding module 100 for high voltage connection may be fastened on the body of the high voltage connector 30 by snap-fitting and then laser-fused.

[0062] In this case, the laser fusion portion is preferably a joint portion between the substrate 110 and the main body of the high voltage connector 30 .

[0063] Figure 7 is shown along Figure 6 An exemplary view of a cross section taken along line AA in FIG. Figure 8 It is shown Figure 7 An enlarged exemplary view of portion B in FIG.

[0064] The sealing retainer 130 protrudes upward from a portion of the base plate 110, and when the housing 10 is assembled, the sealing member 32 is located between the sealing retainer 130 and the housing 10. The sealing member 32 mainly forms a shielding structure of the housing 10, and is made of a deformable rubber material so that the sealing member 32 can fall into the gap at the bottom and block the ventilation line of the diaphragm film 131.

[0065] Therefore, the sealing holder 130 has a support step 132 that supports the sealing member 32 between the housing 10 and the sealing holder 130 to prevent the sealing member 32 located in the assembly portion with the housing 10 from blocking the film 131. Here, the support step 132 may protrude at both ends in the front-rear direction relative to the central portion of the sealing holder 130.

[0066] Because the film 131 is fixed by double injection molding, the pressure of the housing 10 can be compensated. The film 131 in the drawings is used as a single long hole, but it can also have the form of a plurality of holes spaced at regular intervals by double injection molding. Alternatively, the hole size of only a part of the main ventilation line can be formed larger and the remaining holes can be formed smaller, but the film 131 can be double injection molded into the hole. As a result, in the present disclosure, even when the housing 10 is replaced (for example, replaced with a new controller housing), a new connector is not required, and only the corresponding module can be customized and applied, thereby reducing the process and reducing the cost.

[0067] Although the configuration of the present disclosure has been described in detail in the above preferred embodiments, this is for illustrative purposes only, and various modifications and changes can of course be made within the scope of the technical spirit of the present disclosure as allowed.
