DETAILED DESCRIPTION

[0021] The utility model will be further explained in connection with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0022] First embodiment:

[0023] As Figures 1-3As shown in the utility model provides low voltage distribution emergency power supply fast access electric connector, including: shell 101, shell 101 is through from top to bottom, and the middle part is cavity, and the joint 102 is arranged in shell 101, and the joint 102 is metal material, and the other end is connected with cable, and it is the component for transmitting the electric energy in emergency power supply car to the power supply box, and the joint 102 is rotatably connected with the inner wall of shell 101, and the rotatable connection structure of it is as shown in Figure 2 As shown in the utility model provides low voltage distribution emergency power supply fast access electric connector, including: shell 101, shell 101 is through from top to bottom, and the middle part is cavity, and the joint 102 is arranged in shell 101, and the joint 102 is metal material, and the other end is connected with cable, and it is the component for transmitting the electric energy in emergency power supply car to the power supply box, and the joint 102 is rotatably connected with the inner wall of shell 101, and the rotatable connection structure of it is as shown in

[0024] By setting the joint 102 and the like related components rotatably connected with the inner wall of shell 101, when the cable is rotated under the action of external force, the shell 101 is fixed on the power supply box, and the cable in the shell 101 can drive the first fixed seat 104 and the second fixed seat 105 to rotate, thereby reducing the rotation of the shell 101 on the power supply box, and reducing the possibility of the device from the power supply box.

[0025] Second embodiment:

[0026] As Figure 2As shown, a friction plate 110 is provided perpendicularly to the surface of the outer wall of the housing 101. The friction plate 110 is made of rubber. When the housing 101 is inserted into the interface that is compatible with it and installed on the power supply box, the friction plate 110 contacts and is squeezed against the inner wall of the interface.

[0027] By setting the friction plate 110 to increase the friction between the outer casing 101 and the inner wall of the interface on the distribution box, it is beneficial to reduce the risk of the outer casing 101 being pulled out of the interface under the action of external force.
