Description

Technical Field

[0001] The utility model belongs to the technical field of electrical transmission, and in particular relates to a connector structure. Background Art

[0002] In the high-voltage connection system of new energy vehicles, a large number of connectors are used for power transmission. The circuits connected by the connectors include high-voltage circuits for power transmission and interlocking circuits for monitoring high-voltage circuits. The interlocking circuit uses low-voltage signals to check the integrity and continuity of the entire high-voltage circuit, identify abnormal disconnections of the circuit, and disconnect the control electrical components at the high-voltage input end in time. When the two connectors are plugged in, the high-voltage circuit is turned on, and one of the two connectors will be provided with an interlocking connector. When the interlocking connector is connected in place, the high-voltage circuit is turned on. In the event of an abnormality, the interlocking circuit can be disconnected by disconnecting the interlocking connector to disconnect the high-voltage circuit. In order to facilitate assembly and maintenance, a cover body will be provided in the connector so that the high-voltage circuit inside the connector can be easily exposed. In order to protect personnel safety, an interlocking circuit will also be provided between the cover body and the connector. When the cover body is opened, the interlocking circuit is disconnected to disconnect the high-voltage circuit. However, the current high-voltage interlocking parts are generally only set on one connector, or on one connector + cover body. When the two connectors that are plugged into each other have covers, multiple interlocking circuits need to be set to protect safety. The structure in new energy vehicles is compact, and the complex interlocking circuit structure will increase the volume of the connector and affect the assembly of the connector. The setting method of multiple high-voltage interlocking parts and interlocking circuits is difficult to meet the high-voltage interlocking circuits of different models of vehicles. When a suitable connector is installed on a certain model, there may not be enough space to disconnect the high-voltage interlocking parts on other vehicles. In other words, there is a lack of a connector interlocking structure that can meet more usage scenarios. At the same time, multiple interlocking circuits may cause the controller to misjudge, resulting in untimely disconnection of the high-voltage circuit, causing a safety accident. Therefore, a new solution is urgently needed in the prior art to solve the above problems. Utility Model Content

[0038] The first connector 1 is provided with a first cover 11, and the first cover 11 is provided with a first interlocking connector 61; the second connector 2 is provided with a second cover 21, and the second cover 21 is provided with a second interlocking connector 62; the first interlocking loop 4 and the second interlocking loop 5 are respectively provided with a second interface 72 and a third interface 73 that are docked with the first interlocking connector 61 or the second interlocking connector 62;

[0039] When the first connector 1 and the second connector 2 are inserted into place, and the first cover 11 and the second cover 21 are in the covered state, the first interface 71, the second interface 72 and the third interface 73 completely connect the first interlocking circuit 4 and the second interlocking circuit 5, and the controller 3 controls the connector structure to work normally;

[0040] When the first connector 1 and the second connector 2 are disconnected, or the first cover 11 or the second cover 21 is in an open state, the first interlocking circuit 4 or the second interlocking circuit 5 is disconnected, and the controller 3 controls the connector structure to be powered off.

[0041] Take the first interlocking circuit 4 set in the first connector 1 and the second interlocking circuit 5 set in the second connector 2 as an example. The first connector 1 and the second connector 2 are plugged in to realize the electrical transmission of the high-voltage circuit. When the first connector and the second connector 2 are plugged in place, plugging in place means that the high-voltage circuit can conduct current after the first connector 1 and the second connector 2 are connected, the first interlocking connector 61 on the first cover 11 is connected to the first interlocking circuit 4 on the first connector 1, the first interlocking circuit 4 is connected to the second interlocking circuit 5, and the second interlocking connector 62 on the second cover 21 is connected to the second interlocking circuit 5, so that the entire interlocking circuit is turned on, and the controller 3 controls the normal operation of the high-voltage circuit.

By opening the first cover 11 or the second cover 21, the interlocking circuit can be disconnected and then the high-voltage circuit can be disconnected, thereby protecting the electrical safety of the high-voltage circuit.

[0042] In some embodiments, the first interlocking connector 61 and the second interlocking connector 62 are conductive U-shaped pins, which are integrally molded on the first cover 11 or the second cover 21.

Taking the second interlocking loop 5 arranged in the second connector 2 as an example, when the second cover 21 is closed, the two ends of the U-shaped needle on the second cover 21 are respectively connected to the two first interlocking conductors 81 to form the third interface 73, thereby realizing the connection between the second interlocking connector 62 and the second interlocking loop 5.

[0044] In some embodiments, the first interlocking loop 4 includes a second interlocking conductor 82, a third interlocking conductor 83 and a fourth interlocking conductor 84 which are arranged on the first connector 1 or the second connector 2 and are not in contact with each other, one end of the second interlocking conductor 82 and the third interlocking conductor 83 extends to connect with the controller 3, the other end of the second interlocking conductor 82 and one end of the fourth interlocking conductor 84 and the two ends of the U-shaped pin constitute the second interface 72, and the other end of the third interlocking conductor 83 and the other end of the fourth interlocking conductor 84 and the other end of the first interlocking conductor 81 constitute the first interface 71. Taking the first interlocking loop 4 arranged in the first connector 1 as an example, when the first connector 1 and the second connector are plugged into place, one end of the second interlocking conductor 82 is connected to the controller 3, and the other end is connected to the first interlocking connector 61, the fourth interlocking conductor 84, one first interlocking conductor 81, the second interlocking connector 62, another first interlocking conductor 81 and the third interlocking conductor 83 in sequence, and the third interlocking conductor 83 is simultaneously connected to the controller 3 to complete the entire interlocking loop.

[0045] In some embodiments, plug-in terminals are respectively provided on one end of the first interlock conductor 81, the other end of the second interlock conductor 82 and one end of the fourth interlock conductor 84, and plug-in terminals are plugged with the two ends of the U-shaped pin and electrically connected.

The first male terminal 842 is plugged into the first female terminal 812, and the second male terminal 831 is plugged into the second female terminal 813. The plugging of the male terminal and the female terminal can not only generate an electrical connection, but also generate a certain clamping force to prevent the male terminal and the female terminal from being separated.

[0047] In some embodiments, the first interlocking conductor 81, the second interlocking conductor 82, the third interlocking conductor 83 and the fourth interlocking conductor 84 are fixed to the first connector 1 or the second connector 2 by means of snap-fitting or riveting. The snap-fitting method refers to setting corresponding slots on the first connector 1 or the second connector 2, and assembling them through the slots to connect them together. The riveting method is to use rivets to set the connected parts on the first connector 1 or the second connector 2. The advantages of snap-fitting and riveting are fast connection and detachability.

Both the first cover 11 and the second cover 21 can be opened or closed by rotating around the hinge point.
