Abstract

Embodiments of this application provide a connector and an electric apparatus. The connector includes a mounting base, a connection terminal, and a temperature sensor. The connection terminal is fixed to the mounting base, where the connection terminal includes a first connection portion and a second connection portion disposed opposite each other, the first connection portion is configured to electrically connect to an external plug connector, and the second connection portion is configured to electrically connect to an external wire. The temperature sensor is in contact with the connection terminal and configured to detect temperature of the connection terminal. The connector provided in this application can detect the temperature of the connection terminal to help a user find operation anomaly of the connector in time, thereby improving the use safety.

First claim

What is claimed is:

1. A connector, comprising:
a mounting base;
a connection terminal fixed to the mounting base, wherein the connection terminal comprises a first connection portion and a second connection portion disposed opposite each other, the first connection portion is configured to electrically connect to an external plug connector, and the second connection portion is configured to electrically connect to an external wire; and
a temperature sensor in contact with the connection terminal and configured to detect temperature of the connection terminal;
wherein the connection terminal further comprises an intermediate portion, the first connection portion, the intermediate portion, and the second connection portion are connected sequentially in a first direction, and the temperature sensor is in contact with the intermediate portion;
wherein the connection terminal is provided with a mounting hole, the mounting hole being located at the intermediate portion; and at least a part of the temperature sensor is accommodated in the mounting hole;
wherein the mounting base has a communication channel extending along the first direction, and the connector further comprises signal wires, a signal wire being electrically connected to the temperature sensor on one end and passing through the communication channel on the other end to electrically connect to an external controller; and
wherein the mounting base comprises a mounting cavity having a notch, the intermediate portion is inserted into the mounting cavity and connected to the mounting base, the mounting hole is disposed facing toward the notch, and the signal wire sequentially passes through the communication channel and the notch to electrically connect to the temperature sensor.

2. The connector according to claim 1 , wherein the connector further comprises a sealing member having a through hole, the signal wire passes through the through hole, and the sealing member is disposed in the communication channel to seal the communication channel.

3. The connector according to claim 2 , wherein the sealing member comprises a body portion and a boss disposed on the body portion, the body portion and the boss are accommodated in the communication channel, and the boss is configured to abut against an inner wall surface of the communication channel.

4. The connector according to claim 3 ,
wherein the sealing member further comprises a cover portion connected to the body portion, and the communication channel comprises a guide cavity and an accommodating cavity communicating with each other; and
wherein the guide cavity gradually decreases in radial dimension along a direction from the guide cavity to the accommodating cavity, the cover portion mates with the guide cavity, and the body portion and the boss are accommodated in the accommodating cavity.

5. The connector according to claim 1 , wherein the mounting base further comprises a fixing boss protrusively disposed on an inner wall surface of the mounting cavity, the connection terminal further comprises a first restraining boss and a second restraining boss that are protrusively disposed on the intermediate portion, and a restraining recess mating with the fixing boss is formed between the first restraining boss and the second restraining boss.

6. The connector according to claim 5 , wherein the mounting hole runs through the second restraining boss.

7. The connector according to claim 1 , wherein the temperature sensor is in interference fit with an inner wall surface of the mounting hole.

8. The connector according to claim 1 , wherein the connector further comprises a restraining member disposed on the mounting base, the restraining member, the mounting base, and the connection terminal enclose a restraining space communicating with the mounting hole and the communication channel, and a part of the signal wire is accommodated in the restraining space.

9. The connector according to claim 1 , wherein multiple connection terminals and temperature sensors are provided, and the multiple temperature sensors are provided in one-to-one correspondence with the connection terminals.

10. An electric apparatus, comprising:
an electric part;
a controller configured to control the operation of the electric apparatus;
a battery configured to provide electrical energy for the electric part; and
the connector according to claim 1 ,

wherein one of the first connection portion and the second connection portion is electrically connected to the battery and the other is electrically connected to the electric part, and the temperature sensor is signally connected to the controller.
