Abstract

A charging socket has a housing; a charging terminal installed in the housing; an electric adapter installed in the housing; and a temperature sensor for detecting the temperature of the charging terminal. The electric adapter has a body and a connection terminal provided in the body, and the connection terminal has an input end and an output end. The temperature sensor has a flexible lead, which is electrically connected to the input end of the connection terminal, so as to transmit the sensing signal of the temperature sensor to the output end of the connection terminal. The flexible lead of the temperature sensor is electrically connected to the connection terminal of the electric adapter in the charging socket without passing through the rear cover of the charging socket.

First claim

What is claimed is:

1. A charging socket, comprising:
a housing;
an electric adapter installed in the housing;
a heat conduction pad positioned to engage a charging terminal positioned in the housing, the heat conduction pad having a socket provided therein;
a temperature sensor removably positioned in the socket of the heat conduction pad, the temperature sensor configured to detect the temperature of the charging terminal,
the electric adapter comprises a body and connection terminals provided in the body, and the connection terminals have input ends and output ends,
the temperature sensor has flexible leads that extend from the temperature sensor;
a first connector extending from ends of the flexible lead which are removed from the temperature sensor, which terminals of the first connector are electrically connected to the input ends of the connection terminals, so as to transmit the sensing signal of the temperature sensor to the output ends of the connection terminals;
wherein the temperature sensor is installed in the heat conduction pad to be thermally connected with the charging terminal via the heat conduction pad.

2. The charging socket according to claim 1 , wherein
the electric adapter is a lead frame, and the body is a frame body of the lead frame;
a first slot for inserting the first connector is formed on the body, and the input ends of the connection terminals are arranged in the first slot;
when the first connector is inserted into the first slot, the first terminals of the first connector are mated with the input ends arranged in the first slot.

3. The charging socket according to claim 2 , wherein
a first protrusion is formed on one of the a first housing of the first connector and an inner wall of the first slot;
when the first connector is inserted into the first slot, the first protrusion locks the first connector in the first slot.

4. The charging socket according to claim 1 , wherein
the electric adapter is a lead frame, and the body is a frame body of the lead frame;
a mounting slot is formed on the body, and the heat conduction pad is installed in the mounting slot.

5. The charging socket according to claim 1 , wherein
the electric adapter is a lead frame, and the body is a frame body of the lead frame;
the heat conduction pad is fixedly installed on the body.

6. The charging socket according to claim 2 , wherein
the electric adapter is a lead frame, and the body is a frame body of the lead frame;
a second slot for inserting a second connector is formed on the body, and second output ends of the output ends of the connection terminals are arranged in the second slot;
when the second connector is inserted into the second slot, a second terminal of the second connector is mated with the output end of the connection terminal to electrically connect the output end of the connection terminal to a control system of an electric vehicle.

7. The charging socket according to claim 1 , wherein the electric adapter is a circuit board.

8. The charging socket according to claim 1 , wherein
the electric adapter is an integral part formed by insert injection molding, the connection terminal is an insert part, and the body is an injection molded part formed on the connection terminal;
the input ends and the output ends of the connection terminals extend outside the body respectively for electrical connection.

9. The charging socket according to claim 1 , further comprising:
a rear cover fixedly connected with a rear end of the housing to form a rear end cavity;
wherein the flexible leads of the temperature sensor are completely arranged in the rear end cavity.
