[0017] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0018] like Figures 1 to 4 As shown, a compact high-voltage connector with a fuse includes a connector housing 1, a plug-in terminal 2 and a fuse 3. The plug-in terminal 2 is installed in the connector housing 1, and one end of the plug-in terminal 2 extends into the jack of the connector housing 1 to form a plug-in terminal 4. One end of the plug-in terminal 2 is connected to the fuse 3, and the circuit is connected through the plug-in terminal 4. The plug-in terminal 2 is made of conductive material as a whole, so that the fuse 3 is connected to the circuit to achieve the effect of protecting the circuit, which can not only ensure that the terminal and the fuse are connected in series, but also improve the space utilization rate in the connector, and greatly reduce the size of the entire connector.

[0019] Furthermore, if Figure 1 and Figure 2As shown, the plug-in terminal 2 includes a mounting piece 5, a transition piece 6 and a plug-in terminal 4. The two ends of the transition piece 6 are connected to the mounting piece 5 and the plug-in terminal 4 by arc transition. The plug-in terminal 4 is perpendicular to the transition piece 6. The fuse 3 is mounted on the mounting piece 5. A cavity 7 is provided in the connector housing 1. The fuse 3 is arranged in the cavity 7. The plug-in terminal 4 is extended to the jack of the connector housing 1 through the transition piece 6, and the fuse 3 in the cavity 7 is connected at the same time, so that the fuse 3 is connected in series to the circuit.

[0020] Furthermore, if Figures 1 to 3 As shown, both ends of the fuse 3 are provided with L-shaped connecting pieces 8, wherein one end of one L-shaped connecting piece 8 is connected to the connector housing 1 via a first screw 9, and one end of the other L-shaped connecting piece 8 is provided with a second screw 10, and the second screw 10 passes through the mounting piece 5 to connect the connector housing 1, and the mounting piece 5 and the fuse 3 are connected together via the second screw 10, so as to connect the plug-in terminal 2 and the fuse 3 together to the connector housing 1, thereby completing the quick installation of the plug-in terminal 2 and the fuse 3.

[0021] Furthermore, if Figure 1 and Figure 4 As shown, the L-shaped connecting piece 8 includes a vertical piece 11 and a horizontal piece 12. The vertical piece 11 is sleeved on the fuse 3. The vertical piece 11 and the horizontal piece 12 are connected to form an L shape. A strip groove 13 is penetrated on the horizontal piece 12. A round hole 14 is penetrated on the mounting piece 5. The vertical piece 11 is slidably sleeved on the fuse 3. The side wall of the vertical piece 11 is threadedly connected with a screw, and the screw abuts the fuse 3. The vertical piece 11 is slidably sleeved on the fuse 3, which is convenient for adjusting the relative position of the L-shaped connecting piece 8 and the fuse 3, so that the strip groove 13 on the L-shaped connecting piece 8 of the connecting plug terminal 2 corresponds to the round hole 14, and then tighten the screw. The L-shaped connecting piece 8 is limited, and then the second screw 10 is passed through the strip groove 13 and the round hole 14 to be threadedly connected to the connector housing 1, thereby completing the connection between the fuse and the plug-in terminal 2.
