Technical field

This application relates to the field of new energy vehicle connectors, especially to two-core plastic straight connectors.

Background technique

With the development of new energy vehicles, the demand for electrical connectors required by new energy vehicles is also increasing. Connectors include plug modules and socket modules. Socket modules are generally fixed on new energy vehicles. Plug modules are generally connected to external cables and power supplies. When When charging is required, just connect the plug module and the socket module.

However, during the charging process of new energy vehicles, the plug module and the socket module are directly connected. Once impacted by an external force, the plug module is easy to loosen from the socket module, causing the charging process to be suspended. However, the plug module may not be completely detached from the socket module. It is only loose, so it is difficult for users to detect it immediately, resulting in a waste of time, so it needs to be improved.

In this embodiment, there are two second plug locking blocks 37, and two second plug locking blocks are provided. 37 are respectively located at both ends of the second plug link 38 in the width direction; the second plug locking block 37 is located in the locking area and is inclined close to the side wall of the socket housing 1 . The plug housing 2 is integrally formed with a second socket locking block 36. In this embodiment, two second socket locking blocks 36 are also provided, and the position is corresponding to the first plug locking block 33. The socket locking block 36 is arranged obliquely close to the side wall in the direction of the plug housing 2 .

When the socket housing 1 is inserted into the plug housing 2 , the second socket locking block 36 moves toward the second plug locking block 37 . When the inclined surface of the second socket locking block 36 is in contact with the second plug locking block 37 When the inclined surfaces are in contact with each other, the two inclined surfaces guide each other. At this time, one end of the second plug connecting rod 38 close to the second plug locking block 37 is lifted, and the second plug locking block 37 moves toward the second socket locking block. The top wall of 36 moves. At this time, the second plug locking block 37 drives the second plug connecting rod 38 to lift in the direction away from the plug housing 2. The end of the second plug connecting rod 38 away from the second plug locking block 37 moves toward Move closer to the plug housing 2; when the second plug locking block 37 completely crosses the second socket locking block 36, the second plug locking block 37 loses the restriction of the second socket locking block 36, and the second plug connection The rod 38 swings back to reset the second plug locking block 37 to its original height. The second plug locking block 37 restricts the second socket locking block 36 from moving away from the plug housing 2. At this time, the socket housing 1 cannot connect with the plug housing 2. The plug housing 2 is separated.

Referring to Figures 2 and 3, a first socket locking block 32 is provided between the two second socket locking blocks 36. The first socket locking block 32 is integrally formed on the outer wall of the socket housing 1; in this embodiment In this example, there are two first socket locking blocks 32 , and they are arranged in parallel along the width direction of the socket housing 1 .

The side walls of the first plug connecting rod 34 in the width direction are integrally formed on the plug housing 2, and the first plug connecting rod 34 is integrally formed on the plug housing 2. The plug link 34 pivots along its connection point with the plug housing 2 . The end of the first plug link 34 away from the socket housing 1 is located outside the locking area, and the end of the first plug link 34 close to the socket housing 1 is located within the locking area; in this embodiment, the first plug link 34 is provided There are two first plug connecting rods 34 connected at one end located outside the locking area, and a first plug locking block 33 is integrally formed at one end of the two first plug connecting rods 34 located within the locking area.

The first socket locking block 32 is arranged obliquely close to the side wall of the plug housing 2 in the direction, and the first plug locking block 33 is arranged obliquely close to the side wall of the socket housing 1 in the direction. When the socket housing 1 is inserted into the plug housing 2 , the first socket locking block 32 moves toward the first plug locking block 33 . When the inclined surface of the first socket locking block 32 is in contact with the first plug locking block 33 When the inclined surfaces are in contact with each other, the two inclined surfaces guide each other. One end of the first plug connecting rod 34 close to the first plug locking block 33 is lifted, and the first plug locking block 33 faces the end of the first socket locking block 32 . The top wall moves. At this time, the first plug locking block 33 drives the first plug connecting rod 34 to lift in the direction away from the plug housing 2, and the other end of the first plug connecting rod 34 away from the first plug locking block 33 moves closer. The direction of the plug housing 2 moves; when the first plug locking block 33 completely crosses the first socket locking block 32, the first plug locking block 33 loses the restriction of the first socket locking block 32, and the first plug connecting rod 34 The swing reset causes the first plug locking block 33 to return to its original height. At this time, the first plug locking block 33 is in contact with the first socket locking block 32, and the first plug locking block 33 limits the first socket locking block. 32 moves away from the plug housing 2 .
