Description

Technical Field

[0001] This utility model relates to the field of secondary locking structures, and in particular to a secondary locking structure for plugs used in metal connectors. Background Technology

[0002] Metal connectors are primarily used in commercial vehicles and construction machinery, in particularly harsh environments. Connectors used in these environments frequently experience issues such as spring contact loosening or even breakage due to vibration, leading to high-voltage interlock failure or even complete plug detachment. Existing similar products typically use thin metal spring contacts as the connecting element to link the male and female terminals of the metal connector; however, these spring contacts have low strength and are prone to deformation or even breakage. Utility Model Content

[0003] In order to overcome the shortcomings of existing metal connectors where the connection part is prone to breakage and deformation, this utility model provides a secondary locking structure for the plug of a metal connector.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a secondary locking structure for a metal connector plug, including a male connector end, a female connector end, a connecting piece, an elastic part, a first protrusion, a secondary lock, and a second protrusion. The male connector end is hinged with a connecting piece for hooking the first protrusion, and the male connector end is fixed with a secondary lock for hooking the second protrusion. The connecting piece is connected to the male connector end through the elastic part, and the female connector end is provided with the first protrusion and the second protrusion.

[0005] According to another embodiment of the present invention, the secondary lock further includes a front end and a rear seat, the rear seat is fixed on the male end of the connector, the front end is provided with a through hole for the second protrusion to pass through, and the front end protrudes beyond the male end of the connector.

[0006] According to another embodiment of the present invention, the connecting piece is further provided with a second through hole for passing through the first protrusion.

[0007] According to another embodiment of the present invention, the connecting piece is further comprising a stainless steel sheet.

[0008] According to another embodiment of the present invention, the connecting piece is further positioned above the secondary lock.

[0009] According to another embodiment of the present invention, the elastic part is further comprising a stainless steel torsion spring or a stainless steel tension spring.

[0010] The beneficial effect of this utility model is that it uses a connecting piece hinged to the male end of the connector and an elastic part to hook onto the first protrusion on the female end of the connector, and a secondary lock on the male end of the connector to hook onto the second protrusion on the female end of the connector. This application improves the connection stability between the male and female ends of the connector. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the secondary lock of this utility model; In the diagram: 1. Connector male end, 2. Connector female end, 3. Connecting piece, 4. Elastic part, 5. Protrusion one, 6. Secondary lock, 7. Protrusion two, 61. Front end, 62. Rear seat. Detailed Implementation

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the secondary lock of this utility model.

[0014] As attached Figure 1 As shown, a secondary locking structure for a metal connector plug includes a male connector 1, a female connector 2, a connecting piece 3, an elastic part 4, a first protrusion 5, a secondary lock 6, and a second protrusion 7. The male connector 1 is hinged with a connecting piece 3 for hooking the first protrusion 5, and the male connector 1 is fixed with a secondary lock 6 for hooking the second protrusion 7. The connecting piece 3 is connected to the male connector 1 through the elastic part 4, and the female connector 2 is provided with the first protrusion 5 and the second protrusion 7.

[0015] As attached Figure 2 As shown, the secondary lock 6 includes a front end 61 and a rear seat 62. The rear seat 62 is fixed on the male end 1 of the connector. The front end 61 is provided with a through hole for the protrusion 7 to pass through. The front end 61 protrudes beyond the male end 1 of the connector.

[0016] When the male terminal 1 and female terminal 2 of the connector are mated, the front end 61 of the secondary lock 6 contacts the second protrusion 7, and the front end 61 deforms and lifts up due to interference. After the second protrusion 7 aligns with the first through hole of the front end 61, the front end 61 returns to its original shape and uses the first through hole to lock the second protrusion 7. The secondary lock 6 prevents the metal connector from becoming loose.

[0017] The front of the connecting piece 3 is provided with a through hole 2 for passing through the protrusion 5.

[0018] Connecting piece 3 is made of stainless steel. The stainless steel material increases strength, weather resistance, and prevents accidents such as breakage and bending.

[0019] Connecting piece 3 is located above secondary lock 6.

[0020] The elastic part 4 is a stainless steel torsion spring or a stainless steel tension spring. The elastic part 4 can apply pressure to the connecting piece 3, thereby allowing the protrusion 5 to be elastically fastened.

[0021] The working method of this application is as follows: Press down on the tail end of the connecting piece 3, causing the head end of the connecting piece 3 to tilt upwards. Then, align the male end 1 and the female end 2 of the connector. At this time, the through hole 1 of the front end 61 of the secondary lock 6 engages with the second protrusion 7. Next, release the connecting piece 3. Under the rebound of the elastic part 4, the head end of the connecting piece 3 is pressed down until the through hole 1 of the head end of the connecting piece 3 engages with the first protrusion 5, thereby achieving secondary locking and preventing the male end 1 and the female end 2 of the connector from becoming loose.
