The terminal support 31 is provided with a connecting end face 311. A plurality of plug-in sleeves extend vertically from the connecting end face 311. A plug-in through hole 3124 for accommodating the plug-in terminal 32 is provided in the plug-in sleeve. A window 11 is provided on the shell 1. The conversion connector 2 is at least partially exposed outside the shell 1 through the window 11. The plug-in connector 3 is plug-connected with the conversion connector 2 through the window 11, so that the plug-in sleeve is plug-matched with the accommodating through hole, and the plug-in terminal 32 is plug-matched with the conversion terminal 22 one by one and electrically connected.

[0033] With the rapid development and popularization of new energy vehicles, the research and development of charging guns for electric vehicles is particularly important. The conversion connector 2 in the control box of the existing charging gun has no firm clip-on fixing method in the control box. During and after the plug-in connection process between the conversion connector 2 in the control box and the plug connector 3 outside the control box, the conversion connector 2 in the control box is subjected to the plug-in force or the shaking generated during use, causing it to deviate from the predetermined position, resulting in an unstable connection between the conversion connector 2 and the plug connector 3, and separation, resulting in a risk of electricity use.

[0034] The solution of the utility model is that the conversion bracket 21 is fixed to the shell 1 by the clamping structure set between the side wall 213 and the shell 1, which is more conducive to the smooth plugging of the plug-in tube of the terminal bracket 31 and the plug-in interface 212. The plug-in terminal 32 and the conversion terminal 22 can be quickly plugged in one by one and electrically connected, preventing the plugging force generated during the plugging process of the plug-in tube of the terminal bracket 31 and the plug-in interface 212 from causing the conversion bracket 21 to deviate from the preset position in the shell 1, thereby causing the problem of unstable electrical connection.

[0035] In some embodiments, Figure 4-Figure 5 As shown, a stopper 313 half-surrounding the plurality of plug-in cylinders extends from the connection end surface 311 toward the plug-in cylinders, and is used to limit the maximum depth of the plug-in cylinders inserted into the accommodating through hole 3123 .

[0036] The stopper 313 is provided to prevent excessive insertion between the plug-in terminal 32 and the conversion terminal 22 from causing structural damage to both, and to prevent deeper insertion from causing damage to the connection end surface 311 .

[0037] In some embodiments, Figure 3-Figure 4 As shown, the plug-in cylinder includes a plurality of first plug-in cylinders 3121 arranged at intervals and at least one second plug-in cylinder 3122 with a plurality of through holes 3123.

The accommodating through holes include first accommodating through holes 2121 correspondingly plugged into the plurality of first plug-in cylinders 3121 and second accommodating through holes 2122 correspondingly plugged into the second plug-in cylinder 3122. The plug-in terminal 32 and the conversion terminal 22 are respectively plugged into and electrically connected with the corresponding first plug-in cylinder 3121 and the second plug-in cylinder 3122.

[0038] The first plug-in barrel 3121 and the second plug-in barrel 3122 are designed to allow the plug-in terminal 32 and the conversion terminal 22 of the same purpose to be plugged into the first plug-in barrel 3121 to complete the electrical connection, and the plug-in terminal 32 and the conversion terminal 22 of another purpose to be plugged into the second plug-in barrel 3122 to complete the electrical connection.

[0047] In some embodiments, Figure 2 , Figure 3 , Figure 6 As shown, the side wall 213 includes an interconnected mounting portion and a protective portion 2131, the protective portion 2131 is arranged in a conformal manner with the plug-in interface 212, the mounting portion is two mounting ears 2132 connected to the edge of the protective portion 2131, the two mounting ears 2132 are symmetrically arranged relative to the protective portion 2131, a raised mounting seat 12 is arranged around the window 11 inside the shell 1, the mounting seat 12 is arranged in a conformal manner with the inner side surface of the side wall 213, the clamping structure is a clamping groove 2133 arranged on the mounting ear 2132 and a clamping portion 121 corresponding to the clamping groove 2133 is arranged on the mounting seat 12, the clamping portion 121 is clamped with the clamping groove 2133 so that the side wall 213 is snapped onto the mounting seat 12.

[0048] The protective portion 2131 and the plug-in interface 212 are arranged in a conformal manner to better protect the plug-in interface 212, reduce the spatial arrangement of the side wall 213, and reduce material costs. The card slot 2133 on the mounting ear 2132 is engaged with the card portion 121 on the mounting seat 12, and the side wall 213 is fixed to the mounting seat 12. The conversion bracket 21 is fixed to the mounting seat 12 through the side wall 213, which is convenient for plugging the connector 3 and the conversion connector 2, and can also ensure the stability of the plug-in between the two.

[0049] In some embodiments, Figure 8As shown, a second sealing ring 6 is provided between the side wall 213 and the mounting seat 12 .

[0050] The second sealing ring 6 is designed to seal the gap between the mounting seat 12 on the housing 1 and the side wall 213 to prevent impurities and water vapor from entering the gap, thereby ensuring electrical safety when the plug terminal 32 is powered on.

[0051] In some embodiments, Figure 6 As shown, a guide portion 2134 is also provided on the protective portion 2131, two parallel guide strips 122 are provided on the outer periphery of the mounting seat 12 and a clamping portion 123 is provided in the middle of the two guide strips 122, and the guide portion 2134 is embedded in the clamping portion 123 under the guidance of the two guide strips 122.
