Description

Technical Field

[0001] This invention relates to a high-voltage shielded connector capable of protecting the braided mesh connection portion. Background Technology

[0002] In environmentally friendly vehicles such as electric vehicles, the batteries, inverters, and motors are interconnected via cables. Connectors attached to the ends of the cables can transmit high-voltage current through electrical connections to the devices.

[0003] However, the magnetic field generated during the transmission of high-voltage current can affect sensors or electronic equipment, potentially causing vehicle malfunctions. Therefore, high-voltage cables are equipped with magnetic field shielding devices such as braided mesh, and high-voltage shielded connectors capable of shielding the magnetic field are connected to both ends.

[0004] Braided mesh is made by braiding metal wires into a tubular shape. It is attached to a high-voltage shielded connector, allowing its ends to be grounded in the installed state, thus enclosing the exterior of one or more cables.

[0005] High-voltage shielded connectors consist of a metal shielding member surrounding the cable and connecting terminals. One end of the braided mesh mounted on the outside of the cable is engaged with the metal shielding member using a coupling loop to ensure close contact with the outer surface of the metal shielding member.

[0006] However, because the connection between the metal shielding component and the braided wire in this type of high-voltage shielded connector is exposed to the outside, this connection may come into contact with moisture and be easily corroded. Additionally, when external force is applied to the connection between the metal shielding component and the braided wire, the braided wire may separate from the metal shielding component. Summary of the Invention

[0007] One aspect of the present invention is to provide a high-voltage shielded connector that can prevent moisture from flowing in from the outside by sealing the outside of the braided mesh connection portion.

[0008] Another aspect of the present invention is to provide a high-voltage shielded connector that can protect and strengthen the bonding of the braided mesh connection portion by covering it with a braided mesh connection portion.

[0009] Other aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0010] According to one aspect of the invention, a connector includes: an inner housing that houses a connection portion between an end of a cable and a connecting terminal; a metal shielding member that covers an outer surface of the inner housing; a coupling ring that couples an end of a braided mesh covering the cable to the outer surface of the metal shielding member; an outer housing that covers the outer surface of the metal shielding member, wherein a portion of the metal shielding member coupled to the coupling ring is exposed from the outer housing; a braided mesh cover that covers a portion of the braided mesh covering the cable and the coupling ring, the end of the braided mesh cover being coupled to the outer housing in a sealed state; and an external coupling member that covers the portion where the braided mesh cover and the outer housing are coupled, and maintains the coupling between the braided mesh cover and the outer housing.

[0011] The end of the outer housing includes a coupling groove, allowing the end of the woven mesh cover to enter and be engaged.

[0012] The connector further includes: a first locking step extending circumferentially along the outer surface of the braided mesh cover; a second locking step disposed on the inner surface of the outer coupling member to engage with the first locking step; a plurality of locking protrusions disposed on the outer surface of the outer housing; and a plurality of locking grooves disposed on the outer coupling member to be fastened to the plurality of locking protrusions.

[0013] Woven mesh covers include elastic, deformable materials.

[0014] The distance from the end of the woven mesh entering the engagement groove to the first locking step is configured to be greater than the depth of the engagement groove.

[0015] The first locking step is configured to remain spaced apart from the end of the outer housing before the outer connecting member is fastened.

[0016] The first locking step is configured to contact the end of the outer shell through elastic deformation after the outer connecting member is fastened.

[0017] The woven mesh cover includes at least one sealing lip, which is continuously disposed along the circumference of the end that enters the mating groove and contacts the inner surface of the mating groove to seal the gap.

[0018] The sealing lip has a mountain-shaped cross-section and is integrated with the woven mesh cover. Attached Figure Description

Figure 2 It is along Figure 1 The sectional view taken by line A-A' in the figure, and Figure 3 This is an exploded perspective view of a high-voltage shielded connector according to an embodiment of the present invention.

[0028] Reference Figures 1 to 3 The high-voltage shielded connector 100 includes a connection terminal 101, an inner housing 110, an outer housing 120, a metal shielding member 130, a cable seal 140, a cable retainer 150, a coupling ring 160, a braided mesh cover 170, and an external coupling member 180.

[0029] Multiple connection terminals 101 may be provided and connected to the ends of multiple cables 102 respectively. A portion of the connection terminal 101 extends outward from the inner housing 110 to connect to the connector (not shown) of the device, and the portion that connects to the end of the cable 102 is housed in the inner housing 110.

[0030] The inner housing 110 is made of insulating material and houses the portion where one end of the cable 102 connects to the connecting terminal 101. The connecting terminal 101 and the cable 102 can be installed such that they are externally connected to each other before entering the inner housing 110. Figure 2 As shown, since the locking groove 101a is engaged with the locking protrusion 111 inside the inner housing 110, the connecting terminal 101 can be installed on the inner housing 110 without wobbling.

[0031] A cable seal 140 made of elastic material can be installed inside the inner housing 110 to seal the connection between the connection terminal 101 and the cable 102. A cable retainer 150 for stably securing the cable 102 can be installed at the rear end of the inner housing 110 opposite to the connection terminal 101.

[0032] The metal shielding member 130 can be made of aluminum, magnesium, copper, steel, etc., and is formed into a cylindrical shape with an elliptical cross-section. The metal shielding member 130 covers the outer surface of the rear portion of the inner housing 110 to shield magnetic fields and electromagnetic waves. The metal shielding member 130 is connected to one end of a braided mesh 105, which is installed to surround the exterior of one or more cables 102.

[0033] With the end of the braided mesh 105 covering the outer surface of the metal shielding member 130, it is electrically connected to the metal shielding member 130 by fastening a coupling ring 160 to its exterior. The coupling ring 160 is made of metal and is compressed to fasten the exterior of the braided mesh 105, thereby attaching the end of the braided mesh 105 to the outer surface of the metal shielding member 130.

[0034] The outer housing 120 is mounted to cover the outer surface of the metal shielding member 130, except for the area engaged by the coupling ring 160. The outer housing 120 may include a fastening portion 121, which is provided in the form of a flange and has a plurality of fixing screws fastened at one end thereto for securing to the connector of the device.

[0035] Reference Figures 3 to 5 The braided mesh cover 170 covers and protects a portion of the braided mesh 105 located outside the cable 102 and outside the coupling ring 160. The end of the braided mesh cover 170 on the outer housing 120 side is sealed to the outer housing 120. The outer housing 120 includes a continuously formed circumferentially circumferentially groove 122 at its end where it engages with the braided mesh cover 170, allowing the end of the braided mesh cover 170 to enter and engage with it.

[0036] The woven mesh cover 170 can be made of elastically deformable materials such as rubber, silicone, and soft resin. The woven mesh cover 170 can cover and protect the exterior of the portion of the woven mesh 105 that is connected to the metal shielding member 130, protecting the connecting portion (jointing ring fastener) of the woven mesh 105 from external impacts and moisture inflow.

[0037] An external connecting member 180 is installed to cover the exterior of the joint between the woven mesh cover 170 and the outer housing 120, and to maintain the connection between the woven mesh cover 170 and the outer housing 120.

[0038] Reference Figure 4 and Figure 5 The high-voltage shielded connector 100 includes an outer housing 120, a braided mesh cover 170, and a coupling device for securely fastening the outer coupling member 180. The coupling device may include a first locking step 171, a second locking step 181, a plurality of locking protrusions 124, and a plurality of locking grooves 182.

[0039] The first locking step 171 protrudes from the outer surface of the woven mesh cover 170 adjacent to the end that is coupled to the outer housing 120, and is formed continuously along the periphery of the woven mesh cover 170. The second locking step 181 is formed in a stepped shape on the inner surface of the outer coupling member 180 so that the first locking step 171 of the woven mesh cover 170 can be engaged thereon when the outer coupling member 180 is fastened.

[0040] Multiple locking protrusions 124 protrude from the outer surface of the outer housing 120, and multiple locking grooves 182 are provided on the outer connecting member 180 to fasten to the multiple locking protrusions 124 in a corresponding manner.

[0041] Therefore, when the woven mesh cover 170 is installed and the external connecting member 180 is fastened to its outside, the first locking step 171 of the woven mesh cover 170 is engaged by the second locking step 181 of the external connecting member 180, and the locking groove 182 of the external connecting member 180 can be engaged and fastened to the locking protrusion 124 of the outer housing 120 respectively.

[0042] like Figure 6 As shown, the woven mesh cover 170 can be configured such that the distance L2 from its end entering the engagement groove 122 to the first locking step 171 is greater than the depth L1 of the engagement groove 122. Therefore, before fastening the outer engagement member 180, the first locking step 171 of the woven mesh cover 170 can be held spaced apart from the end of the outer housing 120, and as... Figure 5 As shown, after the external connecting member 180 is fastened, it comes into close contact with the end of the outer housing 120 through elastic deformation.

[0043] Thus, after the outer connecting member 180 is fastened, the end of the woven mesh cover 170 that enters the connecting groove 122 comes into close contact with the inner surface of the connecting groove 122 through elastic deformation. Furthermore, when the first locking step 171 is fastened to close contact with the end of the outer housing 120, it seals the gap between the connecting portions, thereby preventing moisture from flowing into the interior from the outside. Therefore, corrosion of the connection portion between the metal shielding member 130 and the woven mesh 105 can be prevented.

[0044] like Figure 6 As shown, the woven mesh cover 170 may include at least one sealing lip 172, which is continuously disposed along the circumference of the end entering the mating groove 122 and contacts the inner surface of the mating groove 122 to seal the gap. The sealing lip 172 has a mountain-shaped cross-section and may be integrally formed with the woven mesh cover 170 during the manufacturing process of the woven mesh cover 170.

[0045] When the external connecting member 180 is tightened, the sealing lip 172 can make close contact with the inner surface of the connecting groove 122 by elastic deformation within the connecting groove 122, thereby enhancing the effect of sealing the gap between the joints.

[0046] Thus, in the high-voltage shielded connector 100 according to this embodiment, since the braided mesh cover 170 and the external connecting member 180 are fastened to the outside of the portion where the metal shielding member 130 is connected to the braided mesh 105, the connection portion between the metal shielding member 130 and the braided mesh 105 is sealed, thereby preventing moisture from flowing into the interior from the outside. Therefore, corrosion of the connection portion between the metal shielding member 130 and the braided mesh 105 can be prevented.

[0047] Furthermore, in the high-voltage shielded connector 100 according to this embodiment, since the braided mesh cover 170 and the external connecting member 180 are installed outside the connection portion between the metal shielding member 130 and the braided mesh 105, the connection of the connection portion of the braided mesh 105 can be enhanced. Therefore, the connection portion between the metal shielding member 130 and the braided mesh 105 can be protected from external impacts.

[0048] As is evident from the above, since the braided mesh cover and the external connecting member are fastened to the outside of the connection portion between the metal shielding member and the braided mesh, the high-voltage shielding connector according to the embodiment of the present invention can prevent moisture from flowing into the interior from the outside by sealing the connection portion between the metal shielding member and the braided mesh, thereby preventing corrosion of the connection portion between the metal shielding member and the braided mesh.

[0049] Furthermore, since the braided mesh cover and the external connecting component are installed outside the connection portion between the metal shielding component and the braided mesh, the high-voltage shielding connector according to the embodiment of the present invention can strengthen the connection portion of the braided mesh, thereby protecting the connection portion between the metal shielding component and the braided mesh from external impacts.

[0050] Although some exemplary embodiments of the invention have been shown and described, those skilled in the art will understand that changes may be made to these exemplary embodiments without departing from the principles and spirit of the invention as defined by the claims and their equivalents.
