The power terminal is electrically connected and fastened by a spring. It is easy to heat up during the power-on process and is an easily damaged component. For this reason, the power terminal and the high-voltage line terminal are often plug-in split type, for example, the power terminal 20 disclosed in Chinese patent document CN220086456U is easy to replace. Utility Model Content

[0003] The technical problem to be solved by the utility model is: how to design a replaceable high-power terminal for a new energy vehicle charging gun to facilitate heat dissipation.

[0004] The technical solution of the utility model is specifically as follows:

[0005] A replaceable high-power terminal for a new energy vehicle charging gun includes a shell, which is divided into a socket pin end shell and a high-voltage line terminal end shell. The socket pin end shell is provided with multiple dividing channels, which divide the socket pin end shell into multiple shell units. A hoop is fixed on the outside of the socket pin end shell.

[0006] The dividing channel extends in a direction parallel to the axis of the housing of the pin end of the socket.

[0007] The plurality of dividing channels are distributed equidistantly in the circumferential direction of the housing of the pin end of the socket.

[0008] An annular groove is arranged on the outer wall of the shell of the pin end of the socket, and the sleeve hoop is fixed in the annular groove.

[0009] A contact spring A and a torsion spring are arranged in the shell of the high-voltage line terminal end, and a contact spring B is arranged in the shell of the socket pin end.

[0010] The ferrule is a metal ferrule.

[0011] Compared with the prior art, the technical effect of the utility model is that the utility model is provided with a split channel, and the split channel can increase the heat dissipation area and facilitate heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the utility model.

[0013] Figure 2 It is a cross-sectional schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] The utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0015] like Figure 1-2 A replaceable high-power terminal for a new energy vehicle charging gun includes a shell, which is divided into a socket pin end shell 20 and a high-voltage line terminal end shell 10. The socket pin end shell 20 is connected to the matching charging socket pin, and the high-voltage line terminal end shell 10 is connected to the high-voltage line terminal.

[0016] The socket pin end housing 20 is provided with a plurality of dividing channels 21 , and the dividing channels 21 divide the socket pin end housing 20 into a plurality of housing units 22 . A ferrule 23 is fixed to the outer side of the socket pin end housing 20 .

[0017] For the convenience of processing, the dividing channel 21 extends in a direction parallel to the axis of the socket pin end housing 20 .

[0018] In order to dissipate heat evenly, a plurality of dividing channels 21 are evenly distributed in the circumferential direction of the socket pin end housing 20 .

[0019] In order to facilitate the fixing of the ferrule 23 , an annular groove 24 is provided on the outer wall of the socket pin end housing 20 , and the ferrule 23 is fixed in the annular groove 24 .

[0020] In order to facilitate electrical connection, a contact spring A11 and a torsion spring 12 are provided in the housing 10 of the high-voltage line terminal end, and a contact spring B25 is provided in the housing 20 of the socket pin end.

[0021] The ferrule 23 is a metal ferrule.

[0022] Its working principle is:

[0023] When the high-voltage line terminal housing 10 is connected to the high-voltage line terminal, the fastening and electrical connection with the high-voltage line terminal is achieved through the finger spring A11 and the torsion spring 12. When the socket pin housing 20 is connected to the matching charging socket pin, the electrical connection with the matching charging socket pin is achieved through the finger spring B25.

[0024] The difference is that if there is a slight error in the size of the matching charging socket pin, the matching charging socket pin can still be clamped by the housing unit 22 through the ferrule 23. However, when the sizes of the matching charging socket pins are different, the width of the dividing channel 21 is different.

[0025] Features of this application:

[0026] S1. The socket pin end housing 20 adopts a slotted structure, which is pre-tightened by a metal hoop to stabilize the plugging and unplugging force, and ensure good contact between the slot and the vehicle end pin, thereby achieving direct current conduction.

[0027] S2. The wiring terminal (this application) and the jack (wiring terminal, also the terminal for connecting high-voltage wires) are of split structure. The wiring terminal is not easy to replace. The high temperature problem may be caused by less contact with the pin and increased resistance. If an integrated terminal is selected, it cannot be replaced. Therefore, a split terminal is used instead. When the resistance of the contact with the pin is large, a new quick-change terminal can be replaced to meet the continued high current and low temperature rise power-on requirements.

[0028] S3. Finger spring structures are added to both ends of the quick-change terminal. A finger spring is added to the front end to ensure full contact with the pin, and a finger spring is added to the rear end to ensure full contact with the wiring terminal. The finger spring structure is added to ensure full contact with the mating end, reduce contact resistance, and ensure the flow of large current.

[0029] S4. The utility model is provided with a split channel, which can increase the heat dissipation area and facilitate heat dissipation.

[0030] S5. The utility model is provided with a split channel, so that the front end of the housing unit 22 is relatively free and can be tightened inwards to ensure the insertion and extraction force during insertion.

[0031] For other contents, please refer to the prior art.

[0032] The above-described embodiments are only preferred embodiments of the present invention. It should be noted that those skilled in the art may make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as within the protection scope of the present invention.
