Problems solved by technology

[0002] New energy vehicles refer to vehicles that are powered entirely by a battery or a combination of a battery and an internal combustion engine. When working, the voltage is as high as several hundred volts, far higher than the safe voltage ;The power transmission of new energy vehicles uses high-voltage cable assemblies, in which the connector is the part used by the vehicle to complete the cable connection and power transmission; currently the connector is connected by plugging, and it only needs to be separated when disconnecting That is, the current connector does not have a locking function, and there will be a phenomenon of false separation when the current passes through the cable, which poses a safety hazard

Embodiment 1

[0034] The present invention provides a high-voltage cable assembly for new energy vehicles. As a specific implementation, refer to Figure 1-Figure 3 , as a specific implementation, it includes a connector 1, the connector 1 includes a first plug 10 and a second plug 11 for plug connection, the first plug 10 includes a plug cavity 101, the second The plug 11 is provided with a plug-in post 110 mated with the plug-in cavity 101, and a first conductive member 111 is arranged in the plug-in post 110, and the plug-in post 110 is configured with at least one first rotating shaft 112, so The rotating shaft 112 is provided with a first gear 113, and the insertion column 110 is provided with an accommodating cavity 1101 around the first conductive member 111, the accommodating cavity 1101 is filled with electromagnetic fluid, and the first rotating shaft 112 extending into the accommodating chamber 1101 is provided with a damping member 114; the inner wall of the socket chamber 101 i...

Embodiment 2

[0037] The present invention provides a high-voltage cable assembly for new energy vehicles. As a specific implementation, refer to Figure 4-Figure 8 , as a specific implementation, the difference between the second embodiment and the first embodiment is that: the specific structure of the connection assembly 102 is: the connection assembly 102 includes a plurality of second rotating shafts that are rotatably arranged in the insertion cavity 101 103. The second gear 104 arranged on the second rotating shaft 103 and the ratchet 105 provided in one-to-one correspondence with the second gear 104, and the outer peripheral surface of the second gear 104 is also equipped with The ratchet surface 1041 that the pawl 105 matches.

[0038] Specifically, the working principle of the connection assembly is: when the first plug 10 and the second plug 11 are plugged in from the separated state, the first gear 113 is meshed with the second gear 104, and since the end of the first shaft is p...

Embodiment 3

[0051] The present invention provides a high-voltage cable assembly for new energy vehicles. As a specific implementation mode, it differs from Example 2 in that reference Figure 9 , Figure 10 , as a further improvement, the present invention also includes a fixing frame 2, the cable fixing frame includes a fixing plate 21 and a plurality of fixing clips 22 arranged at intervals on the spacer plate, and between two adjacent fixing clips 22 The distance is adapted to the length of the connector, and the length of the connector is the dimension when the first plug and the second plug of the connector are plugged together.

[0052] Specifically, refer to figure 1 , in use, the fixing plate 21 is fixed on the vehicle body, and the cable 9 is fixed by the fixing clip 22, by setting the distance between two adjacent fixing clips to match the length of the connector, wherein the adjacent The distance between the two fixing clips is L1, the length of the connector is L2, then L1=(...

Abstract

The invention provides a high-voltage cable assembly for a new energy automobile, and the high-voltage cable assembly comprises a connector, the connector comprises a first plug and a second plug which are in plugging connection, the first plug comprises a plugging cavity, the second plug is provided with a plugging column which is in plugging cooperation with the plugging cavity, the plugging column is internally provided with a first conductive part, and the plugging column is provided with at least one first rotating shaft; a first gear is arranged on the rotating shaft, a containing cavity is formed in the inserting column and surrounds the first conductive part, the containing cavity is filled with electromagnetic liquid, and a damping part is arranged at the end, extending into the containing cavity, of the first rotating shaft; the inner side wall of the plugging cavity is provided with a connecting assembly in engaged connection with the first gear, and when the first plug is pulled out of the plugging cavity, the connecting assembly can drive the first gear to rotate so as to drive the first rotating shaft to rotate, so that by means of the arrangement mode, the connector can be effectively prevented from being separated by mistake when current passes through the interior of the cable, and the service life of the connector is prolonged. And the occurrence of such safety accidents is avoided.

Description

technical field [0001] The invention generally relates to the technical field of new energy vehicles, in particular to a high-voltage cable assembly for new energy vehicles. Background technique [0002] A new energy vehicle refers to a vehicle that is powered entirely by a battery or a combination of a battery and an internal combustion engine. When it is working, the voltage is as high as several hundred volts, which is far higher than the safe voltage; the power transmission of new energy vehicles uses high-voltage cable assemblies, of which The connector is the part used by the vehicle to complete the cable connection and power transmission; the current connector is connected by plugging, and it only needs to be separated when disconnecting. The current connector does not have a locking function, and the wire will appear. There is a phenomenon of false separation when the current passes in the cable, which has potential safety hazards. Contents of the invention [000...
