Compared with traditional cars, one of the characteristics of new energy vehicles is that new energy vehicles often work in a high current and high voltage environment, and this high current and high voltage environment has far exceeded the safety voltage of the human body. However, the reliability of traditional charging seats is low and there are great safety hazards. It can no longer meet the use requirements of today's new energy vehicles. High-voltage interlocking is used in new energy vehicles to determine whether the high-voltage circuit and connector are open by turning on and off the low-voltage circuit. The issuance, reception and judgment of the interlocking signal are all realized by the battery manager. If there is a high-voltage interlocking fault, the vehicle is not allowed to be powered on to ensure safety. However, the current high-voltage interlocking structure lacks a solution that can trigger the high-voltage interlocking without directly touching the high-voltage interlocking parts. Therefore, a new solution is urgently needed in the prior art to solve the above problems. Utility Model Content

[0039] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0040] According to a floating structure connector disclosed in the present invention, it is used to connect with a plug-in connector, and the plug-in connector is provided with a high-voltage interlocking terminal 200, such as Figures 1 to 6 As shown, it includes a connector body 100, at least one conductive terminal 101, a high voltage interlocking member 102 and a cover 103;
[0041] The connector body 100 is used for plugging with the plug-in connector;
[0042] The conductive terminal 101 is disposed in the connector body 100;
[0043] The connector body 100 is provided with a passage 104 for the high voltage interlocking member 102 to pass through;
[0044] The high-voltage interlocking member 102 is at least partially slidably disposed in the channel 104 , and the high-voltage interlocking member 102 is elastically connected to the connector body 100 in the axial direction of the channel 104 ;
[0045] One end of the cover 103 is hinged to the connector body 100, and the other end is snap-fitted to the connector body 100;
[0046] When the cover body 103 is in the covered state, the high voltage interlocking member 102 is pressed to be in conduction with the high voltage interlocking end 200 . The high voltage interlocking member 102 is slidably disposed in the channel 104 .
[0047] When the cover 103 is in the closed state, the high-voltage interlocking part 102 is connected to the high-voltage interlocking terminal 200 to access the circuit where the control device is located. A loose high-voltage circuit will cause a high-voltage power failure, and the vehicle will lose power, affecting the safety of the ride. Therefore, the control device is used to detect whether the high-voltage circuit is loose, and an alarm message is provided to the vehicle controller before the high-voltage power failure, leaving time for the vehicle system to take countermeasures. At the same time, before the vehicle is connected to the charging power supply, if the high-voltage circuit is detected to be incomplete, the system cannot be powered, avoiding accidents caused by virtual connection and other problems.
[0048] According to an embodiment of a floating structure connector disclosed herein, when the cover 103 is in an open state, the high-voltage interlocking member 102 is disconnected from the high-voltage interlocking end 200 .
[0049] When the cover 103 is in the open state, the high-voltage interlocking member 102 is disconnected from the high-voltage interlocking end 200, and the high-voltage circuit in the entire connector body 100 is in a power-off state, thereby preventing operators from touching the high-voltage circuit during maintenance or use and causing casualties.
[0050] Specifically, a mounting seat 105 is fixedly provided in the channel 104, and at least two cantilevers 106 are provided on the mounting seat 105. The cantilever 106 has a slide groove 107 axially parallel to the channel 104. The side wall of the high-voltage interlocking member 102 has at least two protrusions 108, and the protrusions 108 can slide along the slide groove 107.
[0051] By slidably arranging the protrusion 108 along the slide groove 107, it can be ensured that the high-voltage interlocking part 102 slides smoothly relative to the mounting seat 105 and the connector body 100, so that the high-voltage interlocking part 102 can accurately contact the high-voltage interlocking end 200 when the cover body 103 is closed, so as to realize the conduction of the detection circuit where the control device is located.
[0052] More specifically, the high-voltage interlocking member 102 has an abutting surface 109 extending along its circumference, and a spring 110 is disposed between the abutting surface 109 and the mounting seat 105 .
[0053] The spring 110 provides a biasing force away from the high-voltage interlocking end 200 to the high-voltage interlocking component 102, so that the high-voltage interlocking component 102 can be disconnected from the high-voltage interlocking end 200 at the moment when the operator opens the cover 103 as needed, thereby avoiding casualties of the operator during maintenance or use.
[0054] According to an embodiment of a floating structure connector disclosed in the present invention, one end of the cover 103 and the connector body 100 that are engaged with each other is further provided with a screw connection structure 111 for connecting the two. The screw connection structure 111 ensures a stable connection between the cover 103 and the connector body 100, and when it is necessary to open, it can be opened only by a professional operator, thereby preventing the cover 103 and the connector body 100 from being accidentally opened.
[0055] According to an embodiment of a floating structure connector disclosed in the present invention, the high voltage interlocking part 102 has two protruding and conducting contact pins 112, the high voltage interlocking end 200 has two interlocking terminals 201 connecting two interlocking circuits, and the contact pins 112 are plugged or abutted with the interlocking terminals 201. Figure 6 As shown, as shown to achieve the conduction of the detection circuit where the control device is located
[0056] Specifically, the high-voltage interlocking end 200 has two high-voltage interlocking holes 202, the interlocking terminal 201 is disposed in the high-voltage interlocking hole 202, and the contact pin 112 is inserted into the high-voltage interlocking hole 202 to be in conduction with the interlocking terminal 201. Figure 6 As shown, the high-voltage interlocking circuit is connected by connecting the contact pin 112 to the interlocking terminal 201 to achieve conduction.
[0057] According to an embodiment of a floating structure connector disclosed in the present invention, the cover body 103 is provided with an extrusion portion 113 protruding from the inner surface of the cover body 103, and when the cover body 103 is in a covered state, the extrusion portion 113 squeezes the high-voltage interlocking member 102 to conduct with the high-voltage interlocking end 200 and connects the interlocking circuit.
[0058] By providing the extrusion portion 113 , the height of the high voltage interlocking member 102 protruding relative to the bottom wall of the connector body 100 on the side of the cover body 103 is relatively small, so that the connection between the high voltage interlocking member 102 and the mounting seat 105 is relatively stable.
[0059] Specifically, the end of the high-voltage interlocking piece 102 that contacts the extrusion portion 113 is an outwardly convex arc-shaped structure 114 , and the extrusion portion 113 has a concave structure 115 that corresponds to and matches the arc-shaped structure 114 .
[0060] The recessed structure 115 and the arc-shaped structure 114 can ensure that the high-voltage interlocking member 102 has a stable moving direction, thereby ensuring that the contact pin 112 is inserted into the high-voltage interlocking hole 202 .
[0061] According to an embodiment of a floating structure connector disclosed in the present invention, the conductive terminal 101 is columnar, and one end of the conductive terminal 101 is used to electrically connect to the conductive member of the plug connector, thereby achieving connectivity of the high-voltage circuit, ensuring that the battery of the new energy vehicle is transmitted to the vehicle engine through the high-voltage circuit, or ensuring connectivity of the high-voltage circuit between the charging station and the vehicle battery.
[0062] Specifically, the other end of the conductive terminal 101 is covered by the cover body 103 in the closed state, which plays a safety protection role and avoids accidents caused by human touch.
[0063] Specifically, it also includes a bolt 116. The conductive terminal 101 has an axial through passage 117 or a threaded hole. The bolt 116 passes through the through passage 117 or the threaded hole from one side of the cover 103 and is screwed to the conductive member, thereby achieving a stable connection between the conductive terminal 101 and the conductive member to prevent the two from being separated.
[0064] More specifically, the connector has a receiving cavity for receiving the conductive terminal 101, and the cover body 103 is provided with an anti-retraction abutment portion 118, and when the cover body 103 is in the covered state, the anti-retraction abutment portion 118 abuts against the bolt 116. The anti-retraction abutment portion 118 limits the bolt 116 from moving in a direction away from the conductive member, thereby preventing the conductive terminal 101 from being disconnected from the conductive member.
[0065] Specifically, it also includes two stacked flat conductors 119, there are two conductive terminals 101, each conductive terminal 101 is electrically connected to one flat conductor 119 in the connector body 100. Thus, the conductive terminal 101 is connected to the high voltage circuit through the flat conductor 119.
[0066] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
