Problems solved by technology

[0003] However, due to the high contact resistance at the connection point between the wire and the terminal, there is a large voltage drop between the terminal and the wire. Therefore, at the connection point between the wire and the terminal, the heat is generally large, causing more cases of the connection point being blown. , may lead to major safety accidents
[0004] Therefore, there is an urgent need in the field of electrical device technology for a connector that can alleviate the technical problems that the connection point of the wire and the terminal generates a lot of heat and the connection point is often blown.

Embodiment 1

[0054] The present invention provides a connector with a semiconductor cooling device, such as figure 1As shown, the connector includes: a wire 22, a terminal 23 and a semiconductor cooling device 30, the wire 22 is connected to the terminal 23, and the terminal 23 is configured to be connected to an external electrical structure; the semiconductor cooling device 30 has a cooling part 31 and a heat dissipation part 32 , the cooling unit 31 absorbs the heat of the terminal 23 ; and the semiconductor cooling device 30 is electrically connected to the wire 22 .

[0055] In detail, in principle, the semiconductor cooling device 30 is a tool for heat transfer. When a current flows through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer will occur between the two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference to form cold and heat. end. In...

Abstract

The invention provides a connector with a semiconductor cooling device and an automobile. The connector comprises a lead wire, a terminal and a semiconductor cooling device, wherein the terminal is configured such that one end thereof is connected to the lead wire and the other end thereof is connected to an external electrical structure, ; and the semiconductor cooling device is provided with a cooling part and a heat dissipation part, and the cooling part absorbs heat of the terminal. According to the connector, the technical problem that a connection point of the lead wire and the terminal is large in heat productivity and prone to burn out is solved.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a connector with a semiconductor cooling device and an automobile. Background technique [0002] The starting current when the car starts is relatively large, which can reach 150A to 250A, and has relatively high requirements for the carrying capacity of wires and connectors; the working and charging current of electric vehicles is also relatively large, and has relatively high requirements for the carrying capacity of wires and connectors. Require. Usually, the wire has a set rated current, and the calorific value is relatively stable. Using a wire whose rated current meets the requirements can realize the transmission of current. [0003] However, due to the high contact resistance at the connection point between the wire and the terminal, there is a large voltage drop between the terminal and the wire. Therefore, at the connection point between the wire and the ter...
