Specific embodiment
Technical solution provided by the invention is described in detail below with reference to specific embodiment, it should be understood that following specific
Embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.
Embodiment one:
As shown in Figure 1-Figure 3, the connection component provided by the invention with temperature-detecting device, in this case, it is chargings to insert
Seat, including wiring board 4, to temperature-measuring part 2, heat conducting spring plate 3, temperature-detecting device 5.Wherein, to temperature-measuring part for conducting electricity
Stream, in this case, it is terminals, are fixed on Socket casing 1, and heat conducting spring plate is in contact with terminal, in this example, heat conducting spring plate setting
Assist side front (present invention is with, for front, lower section is reverse side above wiring board in Fig. 1), temperature-detecting device uses temperature
Assist side reverse side is arranged in sensor.Temperature sensor for detecting route plate temperature, position preferably with heat conducting spring plate position
It sets corresponding, that is, is arranged immediately below heat conducting spring plate or surface can be quickly obtained to enable thermally conductive pathways most short to thermometric
Member conducts and come heat and measure its temperature.Terminal is generally multiple, therefore, heat conducting spring plate and corresponding temperature detection dress
It sets and multiple groups also can be set, to measure each terminal temperature.Wiring board front is provided with several blind holes 9 (as shown in Fig. 2, in this example
Have 3 blind holes), in Fig. 2, blind hole is located at heat conducting spring plate position, the portion for connecting with heat conducting spring plate or being readily conducted heat by other
Part is indirectly connected with heat conducting spring plate.Blind hole inner wall is covered with heat-conducting layer, blind hole inner wall copper plating in this example, as needed or with
Technology development, can also be used the higher Heat Conduction Material of other thermal coefficients and heat-conducting layer is made.Heat conducting spring plate uses elastic copper sheet,
