Abstract
Provided is an electronic wiring box. The electronic wiring box comprises a pedestal equipped with an upper surface side used for assembling electronic elements and a cover assembled on the pedestal for packaging the electronic elements. The circumambient wall of the pedestal has a double-wall structure comprising an outer circumambient wall of the pedestal and an inner circumambient wall of the pedestal. The circumambient wall of the cover has a double-wall structure comprising an outer circumambient wall of the cover and an inner circumambient wall of the cover. The upper end of the outer circumambient wall of the pedestal is arranged between the outer circumambient wall of the cover and the inner circumambient wall of the cover. The lower end of the inner circumambient wall of the cover is arranged between the outer circumambient wall of the pedestal and the inner circumambient wall of the pedestal. Thus water entering from the gap between the outer circumambient wall of the cover and an outer circumambient wall of the pedestal drips from the gap between the outer circumambient wall of the pedestal and an inner circumambient wall of the pedestal. The inner circumambient wall of the cover extends downwards and excesses the outer circumambient wall of the cover.
Description
Technical field
The present invention relates to a kind of electrical junction box be arranged in automobile.
Background technology
The electrical junction box be arranged in automobile has various structures, all electrical junction boxes (such as, referenced patent document 1) as shown in Figure 4.
Electrical junction box 315 shown in Fig. 4 comprises: substrate masses 311, and such as the electronic component of relay 330 is attached to the upper surface side of this substrate masses 311; And upper cover 310, this upper cover 310 is attached to substrate masses 311 with the electronic component of capping such as relay 330.
Substrate masses 311 has the element installed surface 320 being positioned at substrate masses upper surface place, the guide wall 321 risen from element installed surface 320, perisporium 331 and is formed in the osculum 333 at inner circumferential place of perisporium 331.
The perisporium of upper cover 310 has the double-walled construction comprising periphery wall 334 and internal perisporium 332.
The upper end of the perisporium 331 of substrate masses 311 is between the periphery wall 334 and internal perisporium 332 of upper cover 310.The lower end of the internal perisporium 332 of upper cover 310 is arranged in osculum 333.
For electrical junction box 315, the water entered from the gap 343 between substrate masses 311 and upper cover 310 drips from osculum 333, and is discharged the outside of electrical junction box 315.
In addition, in electrical junction box 315 hereinbefore, for preventing the water entered from the gap 343 between substrate masses 311 and upper cover 310 from arriving element installed surface 320 definitely, element installed surface 320 is arranged as above the lower end of the internal perisporium 332 of upper cover 310.

Summary of the invention
Technical problem
Hereafter the problem of traditional electrical junction box 315 will be described.That is, because the periphery wall 334 of upper cover 310 extends downward beyond internal perisporium 332, so when upper cover 310 is mounted to substrate masses 311, the internal perisporium 332 of upper cover 310 is sightless.Therefore, the internal perisporium 332 assembly manipulation just existing upper cover 310 is difficult to the problem inserting osculum 333 (being difficult to aim at).
If the contraction in length of the internal perisporium 332 of upper cover 310 just can improve assembly manipulation, but in this case, become with regard to there is the water entered from the gap 343 between substrate masses 311 and upper cover 310 problem easily arriving element installed surface 320.
Therefore, the intent of the present invention is to provide a kind of electrical junction box, for this this electrical junction box, easily lid can be mounted to pedestal and water proofing property is high.
Technical scheme
According to an aspect of the present invention, provide a kind of electrical junction box, comprising:
Pedestal, this pedestal has the upper surface side for attaching electronic component; And
Lid, this mounts cover and is connected to described pedestal with electronic component described in capping, wherein
The perisporium of described pedestal has the double-walled construction comprising pedestal periphery wall and pedestal internal perisporium,
The perisporium of described lid has the double-walled construction comprising lid periphery wall and lid internal perisporium,
The upper end of described pedestal periphery wall is between described lid periphery wall and described lid internal perisporium, and the lower end of described lid internal perisporium is between described pedestal periphery wall and described pedestal internal perisporium, make the water entered from the gap between described lid periphery wall and described pedestal periphery wall from the gap drippage between described pedestal periphery wall and described pedestal internal perisporium, and
Described lid internal perisporium extends downward beyond described lid periphery wall.
The lower end of lid internal perisporium is formed as conical by its shape.
Lid internal perisporium can extend downward beyond the element loading surface at the upper surface side place at described pedestal.
Technique effect
According to the present invention, because lid internal perisporium extends downward beyond lid periphery wall, thus when will mount cover be assigned to pedestal time, the lower end of lid internal perisporium can be made under lid internal perisporium is visible situation to be placed in position between pedestal periphery wall and pedestal internal perisporium.Lid can be provided easily to be mounted to pedestal and the high electrical junction box of water proofing property.
According to the present invention, because the lower end of lid internal perisporium is formed as conical by its shape, so the lower end of lid internal perisporium can be placed in the position between pedestal periphery wall and pedestal internal perisporium more easily.
According to the present invention, because lid internal perisporium extends downward beyond the element installed surface at the upper surface place at pedestal, so the water entered from the gap between lid periphery wall and pedestal periphery wall is difficult to arrive element installed surface more, and water proofing property can be improved.
