Specific embodiment
With reference to embodiment, this utility model is described in further detail, but embodiment of the present utility model is not
It is limited to this.
As shown in Fig. 1～Fig. 8, a kind of low internal resistance cover plate of ultracapacitor, including circular cover 1 and metal terminal 2, described
Metal terminal 2 is constituted with encapsulation newel post 4 by drawing newel post 3, and described extraction newel post 3 diameter d1 is less than the diameter of encapsulation newel post 4, institute
State extraction newel post 3 to be connected with described newel post 4 upper end that encapsulates, described circular cover 1 top arranges plastics boss 6, described potted ends
Post 4 inserts described its lower end of plastics boss 6 and runs through described circular cover 1 bottom, described encapsulation newel post 4 lower end setting aluminum platform
5.The material of described circular cover 1 is phenolic resin or engineering plastics.
As shown in Figure 1 to 4, in a described circular cover 1, the described metal terminal 2 of setting is 1 or 2；Described
In the case of for 1, described extraction newel post 3 diameter d1 is 5～10mm to metal terminal 2, and described plastics boss 6 upper surface is to institute
The height h1 stating extraction newel post 3 top surface is 1～3mm, and the diameter d2 of described aluminum platform 5 is 8～18mm, the height of described aluminum platform 5
Degree h2 is 0.2～1.0mm.
As shown in Fig. 5～Fig. 8, described metal terminal 2 in the case of for 2, described extraction newel post 3 diameter d1 be 3～
8mm, described plastics boss 6 upper surface is 1～3mm to the described height h1 drawing newel post 3 top surface, the diameter of described aluminum platform 5
D2 is 5～10mm, and the height h2 of described aluminum platform 5 is 0.2～1.0mm.
