Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a charging socket and a charging gun. Background Technology

[0002] With the development of new energy electric vehicle technology, the requirements for charging performance are becoming increasingly stringent, making the charging gun a crucial component. Temperature rise characteristics are a vital performance parameter for the charging gun. During charging, the temperature of the charging terminals increases continuously with charging time, eventually reaching a dynamic equilibrium. Without precise temperature monitoring and control, the safety of the charging gun's operation will be directly compromised.

[0003] Existing charging guns have a large gap between the different pins of the plug to avoid high-voltage tripping, and there is also a large gap between the pins and the temperature sensor. This results in a long time for the temperature to be conducted from the pins to the temperature sensor, making it impossible for the temperature sensor to quickly and timely monitor the temperature changes of the pins. When an abnormal short circuit occurs in the charging gun plug, the temperature of the pins rises rapidly within a few seconds. The temperature sensor cannot detect and react quickly enough, which can easily lead to fire or short circuit faults in the electric vehicle, affecting safety performance. Utility Model Content

[0031] In the embodiments of this application, reference is made to Figures 1 to 4 This application provides a charging socket 100, which includes: a housing 110, a carrier 120, a charging pin 130, a temperature sensor 140, and a heat-conducting component 150.

[0032] Specifically, the carrier 120 is disposed within the housing 110. For example, the carrier 120 is fixedly installed within the housing 110. The charging pin 130 passes through the housing 110, and a portion of the charging pin 130 is disposed within the housing 110. The temperature sensor 140 is disposed within the housing 110 and is mounted on the carrier 120. The heat-conducting element 150 is disposed within the housing 110 and is also disposed on the carrier 120. The heat-conducting element 150 is thermally connected to the charging pin 130 and the temperature sensor 140, respectively.

[0033] The housing 110 and the support component 120 may be made of plastic injection molding, but are not limited to this.

[0034] The charging pin 130 may be made of any one of copper alloy, tin alloy and brass, but is not limited to this.

[0035] The temperature sensor 140 can be either a resistance temperature detector or a semiconductor temperature sensor, but is not limited to these.

[0036] The heat-conducting component 150 may be made of a thermally conductive material. For example, in this application, the heat-conducting component 150 is made of an insulating thermally conductive adhesive to reduce costs while ensuring the thermal conductivity of the heat-conducting component 150.

[0037] Understandably, when the charging socket 100 is working normally, the temperature of the charging pin 130 will increase continuously as the charging time increases, and the heat generated by the charging pin 130 will be conducted to the heat conductor 150, and then conducted to the temperature sensor 140 by the heat conductor 150, so that the temperature sensor 140 can quickly and timely monitor it.

[0038] In this application, a heat-conducting component 150 is used to thermally connect the charging pin 130 and the temperature sensor 140 to form a heat-conducting structure of charging pin 130-heat-conducting component 150-temperature sensor 140. This enables the temperature sensor 140 to quickly and timely monitor the temperature changes of the charging pin 130, improves the monitoring accuracy of the temperature sensor 140, and ensures that the charging socket 100 can provide timely feedback based on the temperature changes monitored by the temperature sensor 140, thereby improving the safety performance of the charging socket 100.

[0039] In some embodiments, the support member 120 is provided with a receiving groove 121, and the temperature sensor 140 and the heat conductor 150 are both disposed in the receiving groove 121 to limit the temperature sensor 140 and the heat conductor 150, prevent the temperature sensor 140 and the heat conductor 150 from moving freely, and ensure the normal use of the temperature sensor 140; at the same time, it ensures the compactness of the overall structure of the charging socket 100 and reduces the space occupied.

[0040] In some embodiments, the charging socket 100 has a first direction Z and a reference plane P perpendicular to the first direction Z.

[0041] Specifically, along the first direction Z, the orthographic projection of the groove wall of the receiving groove 121 onto the reference plane P is any one of an arc shape, a polygon, or an irregular shape. For example, the orthographic projection of the groove wall of the receiving groove 121 onto the reference plane P can be an arc shape, a triangle shape, or a quadrilateral shape, but is not limited to these, so as to facilitate the processing and forming of the receiving groove 121, improve the processing and forming efficiency of the support member 120, and thus improve the overall processing efficiency of the charging socket 100.

[0042] In some embodiments, refer to Figures 2 to 4 Multiple charging pins 130 are provided, and each charging pin 130 is thermally connected to the heat-conducting component 150; multiple temperature sensors 140 are provided, each temperature sensor 140 is provided in the receiving groove 121, and each temperature sensor 140 is thermally connected to the heat-conducting component 150, and each temperature sensor 140 is respectively located close to a corresponding charging pin 130.

[0043] This application sets up multiple temperature sensors 140 to monitor the temperature of a corresponding charging pin 130 using each temperature sensor 140, thereby further improving the temperature sensing accuracy of the charging socket 100. This ensures that the temperature sensors 140 can efficiently and quickly monitor the temperature changes of different charging pins 130 during charging, thereby further improving the safety performance of the charging socket 100.

[0044] In some embodiments, refer to Figures 2 to 4 The charging socket 100 also includes a plurality of first cables 160, each first cable 160 being electrically connected to each charging pin 130. The first cables 160 are used to electrically connect the charging pins 130 to external electrical components to ensure the normal use of the charging socket 100.

[0045] In some embodiments, refer to Figures 2 to 4 The charging socket 100 also includes a controller, which is electrically connected to the temperature sensor 140. When the temperature sensor 140 senses a temperature change at the charging pin 130, the temperature sensor 140 sends a feedback signal to the controller. After receiving the feedback signal, the controller sends a control command to the corresponding actuator based on the feedback result to control the charging socket 100 to either disconnect the power or maintain normal electrical connection.

[0046] The controller can be any conventional product, conventional control chip, or other conventional product that can realize the control function in this application. No specific restrictions are imposed in this application.

[0047] In some embodiments, refer to Figures 2 to 4 The charging socket 100 also includes a second cable 170, which is electrically connected to the controller and the temperature sensor 140 respectively, so as to realize the electrical connection between the controller and the temperature sensor 140 and ensure that the temperature sensor 140 quickly feeds back the temperature signal to the controller.

[0048] In some embodiments, refer to Figure 3 The carrier 120 has a positioning part 122, and the inner wall of the housing 110 is provided with a positioning groove 111. The positioning part 122 is embedded in the positioning groove 111 to realize the positioning and fixation between the carrier 120 and the housing 110, so as to ensure the overall structural stability of the charging socket 100 and the normal use of the charging socket 100.
