Description

Technical Field

[0001] The utility model relates to a metal connector, in particular to a metal connector assembly with a secondary lock. Background Art

[0002] Metal connectors are primarily used in commercial vehicles and construction machinery, operating in particularly harsh environments. Connectors used in these environments often experience vibration-induced loosening or even breakage of springs, leading to failure of the connector's high-voltage interlock or even complete plug removal.

[0003] Similar products currently on the market generally use thinner stainless steel springs or zinc alloy or aluminum alloy die-cast springs for their plugs, and add a plastic structure at the bottom of the plug spring to prevent it from bouncing away. However, under extreme conditions, strong vibrations can easily cause the spring to deform elastically into a concave structure, causing the spring to loosen from the socket or even break directly. Utility Model Content

[0006] According to another embodiment of the present invention, it further includes hook structures on both sides of the secondary locking platform that are connected to the vertical plates on both sides of the connecting seat, and the lower edge end surfaces of the vertical plates on both sides of the connecting seat are provided with stop blocks and limiting protrusions, and the limiting protrusions are provided with concave points to form two peak points. The hook structure is composed of a first hanging plate, a second hanging plate, and a third hanging plate, and the first hanging plate moves between the stop block and the limiting protrusion on the lower edge end surface of the connecting seat.

[0007] According to another embodiment of the present invention, the locking structure further includes a connecting seat 2 arranged on the plug housing, the connecting seat 2 is connected to the plug shrapnel through a pin shaft, a shrapnel spring is sleeved on the pin shaft, the front end of the plug shrapnel is cooperatively connected to the locking boss, and the rear end is connected to a button that can move back and forth, and a button spring is also provided in the connecting seat 2, one end of the button spring is connected to the button, and the other end is against the inner frame of the connecting seat 2.

[0008] According to another embodiment of the present invention, a paddle is further provided on the upper end of the secondary locking platform.

[0009] According to another embodiment of the present invention, the plug spring is made of stainless steel.

DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, but not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0020] like Figure 1 As shown, the figure includes a socket housing 1 and a plug housing 10, which are connected to each other. The socket housing 1 is provided with a secondary locking structure, and the plug housing 10 is provided with a locking structure that locks with the socket housing 1. The secondary locking structure includes a connecting seat 1 4 provided on the socket housing 1, and a secondary locking platform 2 connected to the connecting seat 1 4 and capable of moving forward and backward. The connecting seat 1 4 is provided with a locking boss 3. The locking structure includes a plug spring 5 that cooperates with the locking boss 3. The lower front end of the secondary locking platform 2 is provided with a lower boss 14. When the secondary locking platform 2 moves backward, it compresses the plug spring 5. The secondary locking platform 2 can move forward and backward on the connecting seat 1 4, providing a shielding effect and effectively preventing the plug spring from accidentally popping open.

[0021] like Figure 2-6 As shown, the secondary locking platform 2 is provided with hook structures on both sides connected to the vertical plates on both sides of the connecting seat 14. The lower edge end surfaces of the vertical plates on both sides of the connecting seat 14 are provided with stop blocks 12 and limiting protrusions 11. The limiting protrusions 11 are provided with concave points to form two peaks. The hook structure is composed of a first hanging plate 13, a second hanging plate 15, and a third hanging plate 16. The first hanging plate 13 moves between the stop blocks 12 and the limiting protrusions 11 on the lower edge end surface of the connecting seat 14. Figure 4 As shown, when the secondary locking platform 2 moves backward, the rear end hanging plate abuts against the stop block 12, the front end of the second hanging plate 15 is limited in the concave point of the limiting protrusion 11, and the lower protrusion 14 below the secondary locking platform 2 is pressed tightly against the top of the plug spring piece 5, which can effectively prevent the plug spring piece from accidentally popping open; Figure 3 As shown, when the secondary locking platform 2 moves forward, the first hanging plate 13 is limited by the limiting protrusion 11. At this time, the lower protrusion 14 leaves the top of the plug shrapnel 5, and there is a certain space above the plug shrapnel 5. The plug shrapnel 5 can be lifted upward under the pressure of the button 7 to perform the unhooking action.

[0022] like Figure 1As shown, the locking structure includes a connecting seat 2 9 arranged on the plug housing 10, and the connecting seat 2 9 is connected to the plug shrapnel 5 through a pin shaft 18. The shrapnel spring 6 is sleeved on the pin shaft 18. The front end of the plug shrapnel 5 is cooperated with the locking boss 3 and the rear end is connected to the button 7 that can move back and forth. A button spring 8 is also provided in the connecting seat 2 9. One end of the button spring 8 is connected to the button 7 and the other end is against the inner frame of the connecting seat 2 9.

[0023] In order to better move the secondary locking platform 2 forward and backward, a paddle 17 is provided on the upper end of the secondary locking platform 2 .

[0024] The plug spring piece 5 is made of stainless steel. The stainless steel material can make the spring piece bear the force more evenly and prevent the spring piece from breaking.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
