[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0017] Embodiment 1
[0018] As Figure 1 shown, the present utility model proposes a signal terminal, including a vertical insertion part 1. The vertical part 5 is the part for inserting with an external terminal. A piercing part 7 is provided on the vertical insertion part 1. The piercing part 7 protrudes from the vertical insertion part 1 and is the part that extends out of the power module housing in the power module. The piercing part 7 is inside the power module to limit the terminal. A connection part 2 is integrally formed at the lower part of the vertical insertion part 1. The connection part 2 and the vertical insertion part 1 can be arranged not on the same straight line. The thickness of the connection part 2 is set according to the position to be actually connected. A bending part 3 is integrally formed at the lower part of the connection part 2. The bending part 3 includes a horizontal part 4 that is parallel up and down. A vertical part 5 is provided at the end of the horizontal part 4. In this embodiment, it forms a C shape. Of course, it can also form a U shape or other structures. The bending part 3 can buffer the terminal. At least one support part 6 is integrally formed on the bending part 3 in the vertical direction. The support part 6 is used to support the bending part 3 to prevent deformation in the vertical direction when stressed. In this embodiment, in order to increase stability, the support part 6 is set to 2 groups and is integrally formed on both sides of the vertical part 5. And the support part 6 offsets from the vertical part 5 to between the two horizontal parts 4. There is a gap between the top and bottom of the support part 6 and the horizontal part 4. When the terminal is stressed too much in the vertical direction of its vertical insertion part 1, the upper horizontal part 4 will press on the end of the support part 6, increasing the strength of the terminal. And the reserved gap also has a certain buffering effect.
[0019] Embodiment 2
[0020] As Figure 1 shown, the present utility model provides a signal terminal, including a vertical insertion part 1. The vertical part 5 is the part for inserting with an external terminal. A puncturing part 7 is provided on the vertical insertion part 1. The puncturing part 7 protrudes from the vertical insertion part 1 and is the part extending out of the power module housing in the power module. The puncturing part 7 is inside the power module to limit the terminal. A connecting part 2 is integrally formed at the lower part of the vertical insertion part 1. The connecting part 2 and the vertical insertion part 1 can be arranged not on the same straight line, and the thickness of the connecting part 2 is set according to the position to be connected actually. A bending part 3 is integrally formed at the lower part of the connecting part 2. The bending part 3 includes horizontal parts 4 parallel to each other up and down. A vertical part 5 is provided at the end of the horizontal part 4. In this embodiment, it forms a C shape. Of course, it can also form a U shape or other structures. The bending part 3 can buffer the terminal. At least one supporting part 6 is integrally formed on the bending part 3 in the vertical direction. The supporting part 6 is used to support the bending part 3 to prevent deformation in the vertical direction when stressed. The difference between this embodiment and Embodiment 1 is that the supporting part 6 is integrally formed on any one of the horizontal parts 4, and the end points to the other horizontal part 4 with a gap left. The supporting part 6 can be set in 1 group, in the middle of the horizontal part 4, or 2 groups, arranged on both sides of the horizontal part 4, and the end points to the horizontal part 4 on the other side. When the terminal insertion receives a large pressure, the upper horizontal part 4 will press on the end of the supporting part 6 to increase the strength of the terminal. Similarly, the bending part 3 will not bend, and the gap left will also have a certain buffering effect.
