This high-current connector can enable the monitoring component to monitor the temperature on the connector in real time, and enable the staff to quickly identify which connector is damaged through the color-changing glue, and enable the alarm component to emit an alarm sound at the first time when the temperature of the connector is too high, reminding the staff to ensure that the staff can timely discover the fault and make remedies to avoid greater losses. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0021] The present application will be described in detail below with reference to the accompanying drawings and specific implementation manners.

[0022] Embodiment 1

[0023] Please refer to Figure 1-6 In, a high-current connector provided in this embodiment includes: an electrical cabinet 1, a plurality of battery cells 101 disposed inside the electrical cabinet 1, a connector 102 disposed between two adjacent battery cells 101, a monitoring component disposed on one side of the inner wall of the electrical cabinet 1 for monitoring the temperature of the connector 102, and an alarm component disposed on one side of the top of the electrical cabinet 1 for reminding the user that a fault occurs in the battery cell 101.

[0024] Among them, the monitoring component includes: a plurality of temperature monitors 2 installed on one side of the inner wall of the electrical cabinet 1, a color-changing glue 201 wrapped around the outer side of the linker 102, a display screen 202 installed on one side of the outer end of the electrical cabinet 1. The color-changing glue 201 on the outer sides of multiple linkers 102 is monitored in real time by the multiple temperature monitors 2, and the monitored temperature values are transmitted to the display screen 202, facilitating the staff to understand the real-time temperature of each linker 102. The linker 102 is wrapped and protected by the color-changing glue 201, and the color-changing glue 201 is made of temperature-sensitive silicone material. When the temperature of the linker 102 rises to 100 degrees, the color of the silicone will change from black to red, enabling the staff to quickly know which linker 102 has an excessive temperature when maintaining and repairing the battery cell 101, thus improving the maintenance efficiency of the staff for the battery cell 101.

[0025] Among them, both ends of the linker 102 are connected with connection terminals 3. One side of the outer end of the connection terminal 3 is connected to the battery cell 101. A control panel 301 is installed on one side of the outer end of the electrical cabinet 1. Adjacent battery cells 101 form a series or parallel battery pack structure through the connection terminals 3 and the linker 102, and it is ensured that energy can be transmitted efficiently and stably between the battery cells 101. The control panel 301 is used to control the use of the battery cell 101, the buzzer 401, and the warning light 402. The battery cell 101, the control panel 301, the buzzer 401, and the warning light 402 are all externally powered. For the control program involved in the present utility model, those skilled in the art can all implement it according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, the alarm component includes: an alarm 4 installed inside one side of the top of the electrical cabinet 1 with a hollow structure, a buzzer 401 installed inside the alarm 4, and a warning light 402 arranged on the top of the buzzer 401. When the temperature value monitored by the temperature monitor 2 for the linker 102 is too high, the temperature monitor 2 will transmit a signal to the buzzer 401 and the warning light 402, causing the buzzer 401 to emit an alarm sound and the warning light 402 to light up, facilitating the staff to quickly know that a failure has occurred in the battery cell 101, and they can make timely remedies to avoid greater losses.

[0028] Among them, the model of the temperature monitor 2 is SMTI RIN06. The temperature monitor 2 is composed of structures such as an infrared sensor and a thermoelectric element. The thermoelectric element avoids receiving the infrared radiation emitted by an object, and this radiation is focused on the thermoelectric element through optical elements such as an optical lens and an infrared filter. When the thermoelectric element receives infrared radiation, a temperature difference will be generated, and then a voltage signal will be generated.

[0029] Among them, sound transmission openings 5 are provided on both outer sides of the alarm 4. A partition 501 is installed inside the alarm 4, and the alarm lamp 402 is located on top of the partition 501. The sound transmission openings 5 are used to ensure that the alarm sound emitted by the buzzer 401 can be transmitted out of the alarm 4, while the partition 501 is used to install the alarm lamp 402 inside the alarm 4. Moreover, the top of the alarm 4 is made of polymethyl methacrylate material, so that the top of the alarm 4 has a certain light transmittance to ensure the normal use of the alarm lamp 402.

[0030] Among them, multiple rectangular placement plates 6 are installed inside the electrical cabinet 1, and multiple battery cells 101 are respectively located on top of the multiple placement plates 6. Multiple openings 601 are provided on the top of the placement plates 6, and a limiting block 602 is installed on one side of the inner wall of the electrical cabinet 1. The placement plates 6 are used to place the battery cells 101 on their tops, facilitating the installation of multiple battery cells 101 inside the electrical cabinet 1. The openings 601 prevent the bottom of the battery cells 101 from completely fitting with the placement plates 6, which affects the heat dissipation of the battery cells 101. The limiting block 602 is used to limit the battery cells 101 to prevent the battery cells 101 from hitting the temperature monitor 2 when moving out of the top of the placement plates 6.

[0031] Among them, a cabinet door 7 is rotatably connected to one side of the outer end of the electrical cabinet 1 through a hinge. A heat dissipation net 701 is inlaid on the outer surface of the cabinet door 7, and a ventilation net 702 is inlaid on the top of the electrical cabinet 1. The cabinet door 7 can rotate through the hinge, and the cabinet door 7 can be rotated to fit with the electrical cabinet 1, thereby protecting the battery cells inside the electrical cabinet 1, and ensuring the air circulation inside the electrical cabinet 1 through the heat dissipation net 701 and the ventilation net 702.

[0032] The specific usage method and function of this embodiment: The connector 102 is wrapped by the color-changing glue 201, and the connector 102 electrically connects two battery cells 101 through the connection terminals 3 at both ends. The temperature monitor 2 monitors the temperature on the outer surface of the connector 102 in real time. When the temperature on the outer surface of the connector 102 is too high, the temperature monitor 2 transmits a signal to the buzzer 401 and the alarm lamp 402, causing the buzzer 401 to emit an alarm sound and the alarm lamp 402 to light up, reminding the staff that the temperature of the connector 102 is too high. The color-changing glue 201 can change from black to red when the temperature of the connector 102 is too high, enabling the staff to immediately distinguish which connector 102 has a high temperature and allowing the staff to take remedial measures to ensure the safety of the battery cells 101.
