Abstract

The invention provides a power module signal terminal. A power module comprises a plastic package housing. A signal terminal comprises a first fixing part, wherein the first fixing part is wrapped bythe plastic package housing; a second fixing part located on the first fixing part, wherein the length of the cross section of the second fixing part is smaller than that of the cross section of the first fixing part; a platform part located on one side of the first fixing part and one side of the second fixing part; and a signal transceiving part located on the platform part, wherein the signal transceiving part is used for connecting internal signals of the power module. According to the invention, the contact area with the plastic package housing can be increased, so that the fixing range can be increased, and the fixing stability can be improved; and in addition, the bonding failure caused by the movement of the fixing position of the power module in an extreme vibration environment can be avoided.

Description

technical field [0001] The invention relates to the technical field of power modules, in particular to a signal terminal of a power module. Background technique [0002] At present, the signal terminal of the power module is usually used for signal transmission, for example, the signal terminal is used as a bridge connecting the circuit board of the client and the internal signal of the module to receive the internal signal of the module and transmit it to the circuit board of the client. Among them, the signal terminal receives the internal signal of the module, which is generally realized through the bonding process. Therefore, the reliability of the bonding between the signal terminal and the power module will directly affect the output of the internal signal of the module, thereby affecting the power of the electronic control system. performance security and integrity. [0003] Among them, the reliability of the bonding between the signal terminal and the power module a...
