Implement charge port hermetically-sealed construction of the present invention, have following beneficial effect: charge port hermetically-sealed construction of the present invention adopts fluid sealant and the dual-seal of flexible sealing plug, has guaranteed the sealing reliability of charge port under adverse circumstances and the reliability of charge port function.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of charge port hermetically-sealed construction of the present invention;
Embodiment
As shown in Figure 1, in an embodiment of charge port hermetically-sealed construction of the present invention, housing 10 has first containing cavity 11 and second containing cavity 12; Flexible sealing plug 20 comprises base portion 21, chock plug 22, and the connecting portion 23 that connects chock plug 22 and base portion 21, and base portion 21 is filled in and is fixed in first containing cavity 11; Charging inlet 30 is positioned at second containing cavity 12, and it comprises insulating body 31 and the metal electrode 32 that is stretched out by insulating body 31, and the opening part that chock plug 22 is filled in second containing cavity 12 is sealed in charging inlet 30 in second containing cavity 12; Gap between gap between the base portion 21 and first containing cavity 11 and charging inlet 30 and second containing cavity 12 is filled with fluid sealant 40, fluid sealant 40 plays fixation on the one hand, also play sealing function on the other hand, fluid sealant can be selected silica gel or epoxide-resin glue for use.
In the present embodiment, for fixing more firm of the base portion 21 that makes flexible sealing plug 20, base portion 21 has back-off 211, first containing cavity 11 has the first step 111 that is used to keep out back-off 211, after first containing cavity 11 is filled in back-off 211 extruding, recovers deformation and just is butted on described step 111 places, guarantee that like this flexible sealing plug 20 is not easy to be got loose by charge port, even if when fluid sealant 40 lost efficacy, because the effect of back-off 211, base portion 21 can not got loose by first containing cavity 11 yet.
Have the second step 121 that is used to keep out described charging inlet 30 for the ease of assembling charging inlet 30, the second containing cavities 12, the insulating body 31 of charging inlet 30 is against on the second step 121, can realize the location of charging inlet 30 easily.Insulating body 31 has an electrode hole 311, metal electrode 32 is stretched out by the bottom surface of electrode hole 311, the described electrode hole 311 of chock plug 22 sealings, has a counterbore 221 on the chock plug 22, this counterbore 221 is over against metal electrode 32, when chock plug 22 was filled in deeply, metal electrode 32 can extend in this counterbore 221.In order to guarantee the fixing reliable of the charging inlet 30 and second containing cavity 12, second containing cavity 12 has the 3rd step 122, the 3rd step 122 is positioned at over against the middle part of insulating body 31, like this after the gap between the insulating body 31 and second containing cavity 12 is full of fluid sealant 40, the two is bonding more reliable.
