Detailed Implementation

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] See Figure 1-2 As shown, a charging gun socket includes a housing 1, a cavity 2 formed in the housing 1, a connection terminal 3 inserted into the cavity 2, and a temperature sensor 4, which is attached to the side wall of the connection terminal 3. The connection terminal 3 is a DC terminal with a terminal power cable 16 connected to its rear end. The temperature sensor 4 is bound to the connection terminal 3 with high-temperature tape, allowing it to directly contact the side wall of the connection terminal 3 during temperature detection.

[0031] In this way, during the charging process of the charging gun socket, the temperature sensor 4 can directly detect the temperature of the connection terminal 3, which greatly improves the accuracy of temperature detection and effectively prevents the connection terminal 3 from overheating, thus improving the safety of the charging process.

[0032] Combination Figure 2As shown, the connecting terminal 3 has a crimping portion 31, which can reflect the heating temperature of the connecting terminal 3 to the maximum extent when the connecting terminal 3 heats up. A mounting groove 5 is formed on the crimping portion 31, and the temperature sensor 4 is housed in the mounting groove 5. The mounting groove 5 is circumferentially formed on the periphery of the crimping portion 31, and the bottom surface of the mounting groove 5 includes multiple mounting planes 51 arranged circumferentially around the connecting terminal 3. The temperature sensor 4 is mounted on one of these mounting planes 51. The temperature sensor 4 can be positioned on the mounting plane 51 and abut against the crimping portion 31 of the connecting terminal 3, further improving the accuracy of temperature detection.

[0033] In this embodiment, combined with Figure 1 and Figure 2 As shown, a rear cover 6 is fitted onto the crimping part 31, and the rear cover 6 is aligned with the insertion cavity 2. The temperature sensor 4 is housed between the rear cover 6 and the mounting groove 5. A first cable outlet 7 is provided at the end of the rear cover 6 away from the insertion cavity 2. A sensor cable 8 is connected to the temperature sensor 4 and passes through the first cable outlet 7. The rear cover 6 can limit the temperature sensor 4 to prevent it from falling off the crimping part 31, while the first cable outlet 7 facilitates the sensor cable 8 to pass through the rear cover 6 and connect to the power supply.

[0034] In this embodiment, combined with Figure 2 As shown, a cable sealing plug 9 is also fitted onto the connecting terminal 3. The cable sealing plug 9 presses against the end of the rear cover 6 away from the insertion cavity 2. The cable sealing plug 9 has a second outlet 10 that communicates with the first outlet 7. The sensor cable 8 passes through the second outlet 10. A sealing plate 11 is also connected inside the second outlet 10. The sensor cable 8 passes through the sealing plate 11 and is press-fitted with the sealing plate 11. The cable sealing plug 9 and the sealing plate 10 are integrally molded from rubber material. The cooperation between the two can effectively improve the sealing performance of the mounting groove 5 and prevent the temperature sensor 4 from reducing its temperature detection accuracy due to the influence of the external environment.

[0035] In this embodiment, a sealing and fixing cover 12 is also fitted onto the connecting terminal 3. The sealing and fixing cover 12 covers the end of the rear cover 6 away from the insertion cavity 2. The cable sealing plug 9 is housed in the sealing and fixing cover 12. The end of the connecting terminal 3 away from the crimping part 31 passes through the sealing and fixing cover 12. The sealing and fixing cover 12 has a third cable outlet 13 that communicates with the second cable outlet 10. The rear cover 6 is provided with a locking block 14, and the sealing and fixing cover 12 is provided with a locking groove 15. The sealing and fixing cover 12 and the rear cover 6 are engaged with each other by the locking block 14 and the locking groove 15, which can prevent the cable sealing plug 9 from detaching from the rear cover 6 and further improve the sealing performance of the mounting groove 5.

[0036] In this embodiment, the insertion cavity 2 includes two cavities 21 arranged side by side. Each cavity 21 is provided with a connecting terminal 3. Each connecting terminal 3 has a temperature sensor 4 attached to its side wall. The two crimping parts 31 constituting the two connecting terminals 3 and the two temperature sensors 4 are all housed in the rear cover 6.
