It is attached with the second fin 40.
In addition, the bottom that Second terminal framework 70 is arranged on the second fin 40 is sentenced the second fin 40 of covering.This
When, first adhesive 100 is arranged between the second fin 40 and Second terminal framework, and passes through second adhesive 110
Second fin 40 and Second terminal framework 70 are attached.
Now, an end 61 at Second terminal framework is will be formed in a downward direction and electrode terminal 62 vertically joins
It is connected to the Second terminal connection unit 51b of the end for being formed in PTC guidance units 50 and while is fixed on this.
In other words, an end 71 of Second terminal framework 70 is vertically attached to the of Second terminal connection unit 51b
One connection groove 500, and the electrode terminal 72 of Second terminal framework 70 is vertically attached to into Second terminal in a downward direction
Second connection groove 510 of connection unit 51b.
Now, the fixed projection 71a being arranged at an end 71 of Second terminal framework 70 is attached to into the first connection
Groove 500, and while by fixed projection 71a by Second terminal framework 70 be fixed to Second terminal connection unit 51b and by
Second terminal connection unit 51b is supported.
As described above, with reference to Fig. 7 and Figure 11, in the electric heater unit 10 (referring to Fig. 1) for assembling, via electrode terminal
61 to 20 supplied with external power of PTC-element, and when PTC-element 20 is heated to uniform temperature, produces from PTC-element 20
Heat is passed to the first fin 30 and the second fin 40.First fin 30 and the second fin 40 will be installed in as cars
Cooling/warm up system air-conditioning equipment housing in heater core near air directly heat.Meanwhile, it is heated
Air may serve to the indoor temperature for raising vehicle from the initial engine start stage to normal operation phase.
As described above, existing electric heater unit (not shown) does not have for supporting or being fixedly installed on a pair of frames
Any separate part of the power supply terminal at (not shown), thus power supply terminal is easily damaged or bends, and which increases defect ratio
Example and reduce reliability.
Therefore, in order to overcome these defects, in this embodiment, by the first and second terminal connection units 51 integratedly
It is arranged on the end at being arranged on the first terminal framework 60 and Second terminal framework 70 that will be attached to of PTC guidance units 50
61st, 71 and electrode terminal 62,72 end, this can support and fixed the first terminal framework 60 and Second terminal framework 70
One end 61 and electrode terminal 62 improve the electric conductivity and heat conductivity of electrode terminal 62 to be not damaged by, further, and reduce
Defective proportion is improving product reliability.
Embodiment of above or accompanying drawing are not limited to according to the electric heater unit of the disclosure as above, but such as to ability
As field technique personnel are apparent, it can be replaced in the scope of the present disclosure in a variety of ways, changes or be changed.
