Battery cap 40 is made up of stainless steel material, which is provided with positive terminal and negative terminal.It should be noted that, because the structural similarity of positive terminal and negative terminal, and inventive concept of the present invention can be applicable to positive terminal and negative terminal simultaneously, so in order to simplified characterization, in this manual positive terminal and negative terminal are collectively referred to as pole 50 without distinction.
Please consult especially shown in Fig. 2, battery cap 40 is provided with installing hole 402, and pole 50 is seal-installed in installing hole 402.Pole 50 is roughly in inverted T-shaped, it trunk portion 504 comprising base portion 502 and extend on the mediad of base portion 502, the lateral wall of trunk portion 504 is provided with external screw thread, to coordinate with establishing female stainless steel nut 90, thus is stably installed in installing hole 402 by pole 50.
Unlike the prior art, in order to make to insulate between pole 50 and battery cap 40, insulating trip 60 between pole 50 and battery cap 40, is provided with.Insulating trip 60 is made up of high-temperature insulation material, indeformable and have good insulation property under the high temperature of 500 DEG C.According to a preferred embodiment of the present invention, insulating trip 60 is made up of ceramic material or mica sheet.
In the shown embodiment, insulating trip 60 is divided into upper insulating trip and the lower insulating trip (mark) of setting independent of one another, upper insulating trip and lower insulating trip are embedded in O-ring seal 80 and lower seal cushion rubber 70 respectively, to avoid insulating trip 60 because of directly stressed and impaired.In addition, upper insulating trip, the cushion rubber bumper 404 with favorable elasticity can also be respectively equipped with between lower insulating trip and battery cap 40, to prevent insulating trip 60 because of stressed and damaged further.According to another implementation of the invention, insulating trip 60 also can direct sintering on the battery cap 40 be positioned at around installing hole 402.
Shown in Fig. 2, in order to ensure good sealing property, above and below insulating trip 60, be respectively equipped with O-ring seal 80 and lower seal cushion rubber 70.Upper O-ring seal 80 and lower seal cushion rubber 70 have good sealing property under high/low temperature, and have good elasticity and corrosion resistance.Upper O-ring seal 80 and lower seal cushion rubber 70 coated upper insulating trip and lower insulating trip respectively, can prevent insulating trip and lower insulating trip damaged because being squeezed.In the shown embodiment, upper O-ring seal 80 and lower seal cushion rubber 70 are all be made up of fluorubber.
Shown in Fig. 1 and Fig. 2, describe the assembling process of electrokinetic cell 10 of the present invention in detail.
The assembling process of battery cap 40 is as follows: first, is sheathed in the trunk portion 504 of pole 50 by the lower seal cushion rubber 70 being inlaid with lower insulating trip; Secondly, the pole 50 being arranged with lower seal cushion rubber 70 is passed from bottom to top from the medium pore (mark) that lower seal 70 and lower insulating trip are offered; Again, the upper O-ring seal 80 being inlaid with upper insulating trip is sheathed in the trunk portion 504 of pole 50; Subsequently, stainless steel gasket 100 is sheathed in the trunk portion 504 of pole 50; Finally, stainless steel nut 90 is tightened in the trunk portion 502 of pole 50, is threaded connection and pole 50 is stably arranged on battery cap 40, lower seal cushion rubber 70 and upper O-ring seal 80 compacted with realize sealing.
In addition, according to another implementation of the invention, insulating trip 60 can sinter on the battery cap 40 be positioned at around installing hole 402.Now, the assembling process of battery cap 40 is as follows: first, is sheathed on by lower seal cushion rubber 70 in the trunk portion 504 of pole 50, lower seal cushion rubber 70 coated insulation sheet 60; Secondly, the pole 50 being arranged with lower seal cushion rubber 70 is passed from bottom to top from the medium pore (mark) that insulating trip 60 is offered; Again, upper O-ring seal 80 is sheathed on pole 50, upper O-ring seal 80 coated insulation sheet 60; Subsequently, stainless steel gasket 100 is sheathed in the trunk portion 504 of pole 50; Finally, stainless steel nut 90 is tightened in the trunk portion 502 of pole 50, is threaded connection and pole 50 is stably arranged on battery cap 40, lower seal cushion rubber 70 and upper O-ring seal 80 compacted with realize sealing.
It should be noted that, in order to improve the reliability be threaded between the trunk portion 504 of stainless steel nut 90 and pole 50 further, between the trunk portion 504 of stainless steel nut 90 and pole 50, screw thread fixing glue can also be added.
The assembling process of electrokinetic cell 10 of the present invention is as follows: first, battery 30 is positioned in battery container 20; Secondly, in battery container 20, electrolyte is poured into; Finally, the battery cap 40 prepared according to previous process is installed on the top of battery container 20 by laser welded seal.During use, one end and the battery 30 of pole 50 are electrically connected, and the other end is connected with external circuit.
When in use there is high temperature in electrokinetic cell 10 of the present invention, the insulating trip 60 be made up of pottery or mica can not melt or burnout, therefore pole 50 can be avoided directly to contact with battery cap 40 by after high temperature, prevent positive and negative pole all to contact with battery cap 40 short circuit caused, significantly improve the security performance of electrokinetic cell 10.
