[0033] Please see Figure 1-5 This application provides a high-voltage, high-current shielded cable connector, including: a cable 30, a shielding structure 10, and a terminal connector 20; the terminal connector 20 is disposed at one end of the shielding structure 10 and is used to connect with an external board-end connector; one end of the cable 30 is fixed inside the shielding shell 11 and is connected to the terminal connector 20, and the cable 30 is connected to the external board-end connector through the terminal connector 20 to realize the transmission of current or signal; the shielding structure 10 is used to isolate the electromagnetic field in the cable 30 from the external electromagnetic signal to avoid electromagnetic interference.

[0034] Specifically, cable 30 is a high-voltage cable 30, capable of withstanding high voltage and high current. The shielding structure 10 includes a metal shielding shell 11 and a conductive member 12. The conductive member 12 is fixed to the shielding shell 11 and electrically connected to it; the conductive member 12 and the terminal connector 20 are located at the same end of the shielding shell 11; when plugged into an external board connector, the conductive member 12 is connected to the mounting panel of the external metal enclosure, thereby electrically connecting the shielding shell 11 and the external mounting panel together to ground, thus achieving the purpose of shielding against external electromagnetic interference.

[0035] Please see Figure 2Furthermore, in some embodiments, the shielding shell 11 includes an upper shielding cover 111 and a lower shielding cover 112, which are fastened together to form a receiving cavity. A terminal connector 20 is disposed at one end of the receiving cavity for easy insertion with an external board-end connector. The upper shielding cover 111 has a first wire groove 1111 at its end away from the terminal connector 20, and the lower shielding cover 112 has a second wire groove 1121 opposite to the first wire groove 1111 at its end away from the terminal connector 20. The cable 30 is clamped within the first wire groove 1111 and the second wire groove 1121, and the cable 30 is secured by the first wire groove 1111 and the second wire groove 1121 to prevent the cable 30 from detaching from the terminal connector 20. The embodiments of this application use a metal shielding shell 11 to provide higher holding force for the cable 30, enabling it to operate in highly complex environments and effectively shielding against electromagnetic interference generated by other components during operation. In addition, it has stronger resistance to impact and dust, further ensuring the stability of the cable 30 connector.

[0036] Furthermore, in some embodiments, the inner wall surfaces of the first wire groove 1111 and / or the second wire groove 1121 are provided with a plurality of protruding ridges. These protruding ridges abut against the outer insulation layer of the cable 30, thereby increasing the holding force of the first wire groove 1111 and the second wire groove 1121 on the cable 30 by compressing the outer insulation layer of the cable 30, thus improving the stability of the cable 30 connector. Preferably, the length direction of the protruding ridges is perpendicular to the length direction of the cable 30, so as to further increase the clamping force of the shielding shell 11 on the cable 30.

[0037] Please see Figure 2 and Figure 3 Furthermore, in some embodiments, the shielding structure 10 also includes a wire clamping structure 113 disposed inside the receiving cavity, which is used to further enhance the clamping effect on the cable 30 and prevent the end of the cable 30 from disconnecting from the terminal connector 20, causing an open circuit and affecting the connection stability of the cable 30 connector. Specifically, the wire clamping structure 113 includes a wire clamp 1133 and a positioning part 1131, and the cable 30 is fixedly clamped in the positioning part 1131 and the wire clamp 1133. The positioning part 1131 is provided with a groove for supporting and accommodating the cable 30. As a matching fit, the middle part of the wire clamp 1133 is also provided with a groove to accommodate the cable 30. Preferably, the contact surface between the wire clamp 1133 and the cable 30 is provided with protruding ribs to increase the clamping force on the cable 30.

[0038] Furthermore, the positioning part 1131 is disposed on the inner wall surface of the upper shielding cover 111 or the lower shielding cover 112, and is integrally formed with the upper shielding cover 111 or the lower shielding cover 112, reducing the number of parts to simplify the assembly process, saving costs, and improving the stability of the connector.

[0039] Furthermore, the wire clamping structure 113 also includes locking portions 1132 located on both sides of the positioning portion 1131. Similarly, the locking portions 1132 and the positioning portion 1131 are located on the inner wall of the upper shielding cover 111 or the lower shielding cover 112, and are integrally formed with the upper shielding cover 111 or the lower shielding cover 112. The two ends of the wire clamp 1133 are fixed to the locking portions 1132 by fasteners. The wire clamp 1133 is made of metal and is electrically connected to the shielding shell 11 through the locking portions 1132, realizing electrical connection between the shielding components inside and outside the shielding shell 11, achieving full-angle shielding and improving the shielding effect. It can be understood that a sleeve can be fitted on the cable 30 at the position where it is clamped with the wire clamping structure 113 to fill the gap between the cable 30 and the wire clamping structure 113, improve the compaction tightness of the two, and improve the holding force of the wire clamping structure 113 on the cable 30.

[0040] Preferably, the locking part 1132 and the positioning part 1131 are both provided on the inner wall surface of the lower shielding cover 112. During assembly, the cable 30 is first placed in the fixing part, and then the wire clamp 1133 is locked in the locking part 1132 to realize the fixed connection between the cable 30 and the lower shielding cover 112. Then the shielding cover 111 is closed to complete the assembly of the cable 30 connector.

[0041] Please see Figure 1 , Figure 4 and Figure 5 Furthermore, in some embodiments, the guide member 12 is disposed on the outer wall surface of the shielding shell 11. The guide member 12 includes a protruding abutment portion 122, which elastically abuts against the mounting panel of the external metal housing. This can more effectively ensure the contact stability between the shielding structure 10 and the mounting panel, and increase the number of durable insertion and removal cycles. In this embodiment, there are two guide members 12, respectively disposed on the outer wall surfaces of the upper shielding cover 111 and the lower shielding cover 112, to increase the stability of the connection with the external metal housing.

[0042] Furthermore, the connector 12 also includes a fixing part 121 and a snap-fit ​​part 123 respectively disposed at both ends of the abutment part 122; the fixing part 121 is fixed to the outer wall surface of the shielding shell 11; the snap-fit ​​part 123 is bent and fastened to the inner wall surface of the shielding shell 11 to prevent the connector 12 from becoming loose from the shielding shell 11 after repeated insertion and removal of the cable 30 connector, thereby affecting its shielding effect.

[0043] Preferably, the outer wall of the shielding shell 11 is provided with a plurality of riveting posts 1112, and the fixing part 121 is provided with riveting holes for riveting and fixing the guide 12 to the shielding shell 11. It is understood that the shielding shell 11 and the guide 12 can also be connected by welding or other connection methods, and are not limited thereto.

[0044] Please see Figure 3 and Figure 4 Furthermore, in some embodiments, the terminal connector 20 and the shielding housing 11 are fastened together by a snap-fit ​​structure, which includes a hook 211 and a latch 1114, one of which is located on the outer wall of the terminal connector 20 and the other on the shielding housing 11. As an example, in this embodiment, the outer wall of the terminal connector 20 is symmetrically provided with two protrusions as hooks 211, and the shielding housing 11 is provided with two cutouts as latches 1114, so that the protrusions are engaged into the cutouts to secure the terminal connector 20 and the shielding housing 11.

[0045] Preferably, in this embodiment, the side walls of the upper shielding cover 111 and the lower shielding cover 112 are respectively provided with grooves, and the upper shielding cover 111 and the lower shielding cover 112 are closed, forming a cut. In this configuration, during the assembly process, the terminal connector 20 connected to the cable 30 is placed in the groove, and then the cable 30 is fixed, which facilitates the installation and positioning of the terminal connector 20 and the cable 30.

[0046] Furthermore, in some embodiments, the upper shielding cover 111 and / or the lower shielding cover 112 are provided with a backstop 1122. The backstop 1122 is located in the receiving cavity and abuts against the insertion end of the cable 30 of the terminal connector 20. When the terminal connector 20 is inserted with the external board end connector, the backstop 1122 abuts against the terminal connector 20 to prevent the terminal connector 20 from retracting into the receiving cavity.

[0047] Furthermore, the terminal connector 20 includes a terminal housing 21 and a wiring terminal 22 embedded inside the terminal housing 21. The wire core at the end of the cable 30 is inserted into the wiring terminal 22. When the terminal connector 20 is plugged into the external board connector, current or signal transmission is realized, which will not be described in detail here.

[0049] (1) By setting the conductor to connect the metal shielding shell and the external mounting panel, a full-angle shielding effect can be effectively formed, effectively resisting electromagnetic interference, and at the same time meeting the requirements of high voltage and high current.

[0050] (2) The metal conductor has a protruding abutment part that elastically abuts against the external mounting panel, which can more effectively ensure the contact stability between the shielding structure and the mounting panel and increase the number of durable insertion and removal cycles.
