[0037] like Figure 1-5 As shown, this utility model provides a female end structure for a connector, comprising:

[0038] Mounting body 100 and a first mounting hole 201 and a plurality of second mounting holes 202 provided on mounting body 100; one end of first terminal 300 passes through the first mounting hole 201 and is connected to mounting body 100; one end of a plurality of second terminals 400 passes through a plurality of second mounting holes 202 and is connected to mounting body 100 respectively; wherein, a ventilation channel 500 is formed inside the first terminal 300; each of the plurality of second terminals 400 is provided with a connection port, and a heat sink 600 is provided on the connection port;

[0039] During use, the first terminal 300 and the second terminal 400 are connected to the male terminal for high-current transmission, generating heat during this process. The first terminal 300 has an internal ventilation channel 500, which facilitates heat exchange with the outside, improving its heat dissipation. The heat sink 600 connects the terminal to the male terminal and creates a gap between the second terminal 400 and the male terminal, further enhancing heat exchange. Additionally, one end of the first terminal 300 and several second terminals 400 are located outside the mounting body 100; therefore, the heat generated during use is transferred along with these terminals and facilitates heat exchange with the outside, further improving heat dissipation.

[0040] The technical solution of this utility model involves respectively setting a first terminal 300 and a plurality of second terminals 400 on the mounting body 100, and fixing the first terminal 300 and the plurality of second terminals 400 through the cooperation of the first mounting hole 201 and the plurality of second mounting holes 202; a ventilation channel 500 is formed inside the first terminal 300, and a heat sink 600 is provided on the plurality of second terminals 400; during use, the ventilation channel 500 and the plurality of heat sinks 600 cooperate to dissipate heat from the first terminal 300 and the plurality of second terminals 400 respectively; thereby, the first terminal 300 and the plurality of second terminals 400 can be effectively cooled, so that the first terminal 300 and the plurality of second terminals 400 do not have to be used at high temperature for a long time; compared with the prior art, the technical solution of this utility model has a reasonable structure and can effectively cool the first terminal 300 and the plurality of second terminals 400, thereby avoiding the first terminal 300 and the plurality of second terminals 400 from being used at high temperature for a long time, and improving the service life of the first terminal 300 and the plurality of second terminals 400 while avoiding problems such as fire.

[0041] Due to the different operating environments of the connectors, it is necessary to seal between the terminals and the mounting body 100 to prevent foreign objects from entering. Therefore, in this utility model, a first sealing body 701 and several second sealing bodies 702 are preferably provided. The first sealing body 701 is disposed between the first terminal 300 and the mounting body 100. Several second sealing bodies 702 are respectively disposed between several second sealing bodies 702 and the mounting body 100. Specifically, a first sealing groove is provided around the first mounting hole 201. A second sealing groove is provided around each of the several second mounting holes 202. In the installed state, the first sealing body 701 is placed in the first sealing groove, and the several second sealing bodies 702 are placed in the several second sealing grooves. After the first terminal 300 and several second terminals 400 are installed, the first sealing body 701 and the second sealing bodies 702 can be pressurized through the first terminal 300 and several second terminals 400, thereby achieving a seal between the first terminal 300 and several second terminals 400 and the mounting body 100.

[0042] It should be noted that, in this utility model, preferably, two second mounting holes 202 are provided, and the two second mounting holes 202 are arranged opposite to each other on both sides of the first mounting hole 201; and a second terminal 400 is respectively provided in the two second mounting holes 202; in addition, thermally conductive insulating adhesive is applied to both the first sealing body 701 and the second sealing body 702, and sealing is achieved simultaneously through the cooperation of the first sealing body 701 and the second sealing body 702 with the thermally conductive insulating adhesive; preferably, both the first sealing body 701 and the second sealing body 702 are made of rubber.

[0043] like Figure 4 and Figure 5As shown, the mounting body 100 is provided with a first sliding groove 101 corresponding to the first mounting hole 201; in the installation state, one end of the first terminal 300 passes through the first mounting hole 201 and is placed in the first sliding groove 101; the mounting body 100 is provided with a plurality of second sliding grooves 102 corresponding to a plurality of second mounting holes 202; in the installation state, one end of a plurality of second terminals 400 passes through a plurality of second mounting holes 202 and is placed in a plurality of second sliding grooves 102 respectively; when connecting the first terminal 300 and the plurality of second terminals 400, one end of the first terminal 300 and one end of the plurality of second terminals 400 pass through the first mounting hole 201 and the plurality of second mounting holes 202 respectively and are placed in the first sliding groove 102 respectively. The first terminal 300 slides within the first slide 101 and the second slide 102. Additionally, fixing holes are provided on the first slide 101 and the second slide 102, and through holes are provided at one end of the first terminal 300 and the plurality of second terminals 400. When the first terminal 300 and the plurality of second terminals 400 move within the first slide 101 and the second slide 102 respectively, the through holes on the first terminal 300 and the plurality of second terminals 400 align with the fixing holes on the first slide 101 and the second slide 102. The first terminal 300 and the second terminals 400 are then fixed to the first slide 101 and the second slide 102 using bolts or screws, thus completing the installation of the first terminal 300 and the plurality of second terminals 400.

[0044] like Figure 1 As shown, this utility model also includes a detection device 900. One end of the detection device 900 is disposed inside the mounting body 100 and adjacent to the first terminal 300. The other end of the detection device 900 can be connected to a controller in the prior art, such as a microcontroller or PLC controller. When installed on equipment such as new energy vehicles, it can also be connected to an on-board controller. The detection device 900 acquires the current, voltage, and temperature parameters of the first terminal 300 and sends the detection results to the controller. When the detection results (overcurrent, overvoltage, or high temperature) exceed a predetermined value, the controller controls the first terminal 300 and several second terminals 400 to disconnect from the external connection for protection. In this utility model, the preferred detection device 900 includes a voltage sensor, a current sensor, and a thermistor sensor, which are respectively connected to the controller via wires.

[0045] like Figure 3As shown, the second terminal 400 includes a terminal body 401 and a terminal cavity 402 formed within the terminal body 401; a connection port is formed on the terminal body 401, one end of the terminal body 401 passes through the second mounting hole 202 and is connected to the mounting body 100; a heat sink 600 passes through the connection port and is disposed within the terminal cavity 402; specifically, a through hole is provided on the terminal body 401, and when the terminal body 401 slides and the through hole is opposite to the fixing hole, the through hole and the fixing hole are fixed by bolts and screws, etc.; in addition, when connected to the male terminal, the terminal on the male terminal is inserted into the terminal cavity 402 and connected to the terminal cavity 402 for subsequent current transmission;

[0046] Additionally, the heat sink 600 includes a positioning plate 601 and a plurality of heat sinks 602 disposed on the positioning plate 601; the positioning plate 601 is adapted to the terminal cavity 402; such as Figure 3 As shown, the positioning piece 601 is placed inside the terminal cavity 402 and snapped into the terminal cavity 402. When the male terminal is inserted into the terminal cavity 402, it will compress several heat sinks 602, and the heat sinks 602 will exert a reaction force on the male terminal, so that the heat sinks 602 and the male terminal are in a tight fit. Since the positioning piece 601 is in contact with the terminal cavity 402, the connection between the second terminal 400 and the male terminal is realized. Due to the arrangement of the heat sinks 602, there is no direct contact between the male terminal and the terminal cavity 402. This can form a gap between the terminal cavity 402 and the male terminal. During use, heat exchange can be carried out with the outside through the gap, improving the cooling effect of the second terminal 400 and the male terminal. Preferably, the positioning piece 601 and the heat sinks 602 are both made of copper alloy.

[0047] Of course, in this invention, a resistance-reducing layer is also provided on the outer surface of the first terminal 300 and the plurality of second terminals 400; the contact resistance of the first terminal 300 and the plurality of second terminals 400 is reduced by the resistance-reducing layer, thereby reducing the heat generated by the first terminal 300 and the second terminal 400; in this invention, the preferred resistance-reducing layer is a silver plating layer.

[0048] like Figure 6 and Figure 7As shown, the mounting body 100 is also connected to a protective shell 800, and the first terminal 300 and several second terminals 400 are respectively inserted into the protective shell 800. The protective shell 800 can protect the first terminal 300 and several second terminals 400 from external contact. Specifically, the protective shell 800 is provided with a first protective cavity 801 and several second protective cavities 802. In the installed state, the first terminal 300 is inserted into the first protective cavity 801, and several second terminals 400 are respectively inserted into the several second protective cavities 802. The first protective cavity 801 and several second protective cavities 802 protect the first terminal 300 and several second terminals 400 respectively, and at the same time, the first protective cavity 801 and several second protective cavities 802 cooperate with the first terminal 300 and several second terminals 400 for limiting. In this utility model, the protective shell 800 and the mounting body 100 are connected by bolts.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
