Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, 2, 3, the process for filling colloid of a kind of safety-increasing epoxy potting driving box that the embodiment of the present invention provides, comprise the steps:
(1) arranging some driving plate glue-filling slots 5 independent of each other and wiring glue-filling slot 7 on driving box, wiring glue-filling slot 7 is positioned at the both sides driving plate glue-filling slot 5, and these some driving plate glue-filling slots 5 are driven the dividing plates 4 on box to be formed by some being plugged in;
(2) driving plate 6 is installed in driving plate glue-filling slot 5, the wiring driving plate 6 is installed in wiring glue-filling slot 7;
(3) butted line glue-filling slot 7 encapsulating;
(4) to driving plate glue-filling slot 5 encapsulating.
When above-mentioned steps (3) and step (4) encapsulating, the encapsulating thickness of described driving plate glue-filling slot 5 exceedes more than the height 3mm driving plate 5, and the encapsulating thickness of described wiring glue-filling slot 7 is less than the encapsulating thickness driving plate glue-filling slot 5.
Process for filling colloid of the present invention is by driving the some dividing plates of grafting 4 on box to form multiple driving plate glue-filling slot 5 independent of each other, when driving when being smaller in size than the size driving plate glue-filling slot 5 of plate 6, is directly put in by driving plate 6 in driving plate glue-filling slot 5; When driving when being sized larger than the size driving plate glue-filling slot 5 of plate 6, it is possible to the size cases according to driving plate 6 takes out one or more dividing plates 4, until plate 6 can will be driven to put between two dividing plates 4; Then butted line glue-filling slot 7 encapsulating; Finally to driving plate glue-filling slot 5 encapsulating. Owing to the driving plate glue-filling slot 5 being placed with driving plate 6 is only carried out encapsulating by the process for filling colloid of the present invention, it does not have place the driving plate glue-filling slot 5 not encapsulating driving plate 6, therefore can greatly reduce encapsulating amount, save encapsulating cost. It addition, the process for filling colloid of the present invention has only to drive the encapsulating thickness of plate glue-filling slot 5 to exceed more than the height 3mm driving plate 6, to meet the requirement of explosion proof of GB/T3836.3; And the encapsulating thickness of wiring glue-filling slot 7 less than the encapsulating thickness driving plate glue-filling slot 5, can both meet requirement of explosion proof, can be greatly saved again encapsulating cost.
Such as Fig. 1, 2, shown in 3, the embodiment of the present invention additionally provides a kind of safety-increasing epoxy potting driving box, including a upper cover 1, one casing 2 and a drain pan 3, casing 2 is through hollow frame structure, casing 2 includes one first opening 21 and one second opening 22 being oppositely arranged, drain pan 3 is closed for one end, the frame structure of one end open, drain pan 3 includes a base plate 31 and four and base plate 31 side plate 32 connected vertically, first opening 21 of casing 2 seals with upper cover 1 and coordinates, second opening 22 of casing 2 is fixing with the base plate 31 of drain pan 3 to be connected, the dividing plate 4 of some grafting vertical with the base plate 31 of drain pan 3 it is provided with in casing 2, one is formed for placing the driving plate glue-filling slot 5 driving plate 6 between each two dividing plate 4, drive plate 6 parallel with drain pan 3 and fixing connection, the some wiring glue-filling slots 7 for the wiring driving plate 6 being carried out encapsulating of the base plate 31 of drain pan 3 being respectively arranged at two ends with in the first direction.
The present invention, by arranging the dividing plate 4 of multiple grafting vertical with the base plate 31 of drain pan 3 in casing 2, forms one for placing the driving plate glue-filling slot 5 driving plate 6 between each two dividing plate 4. When driving when being smaller in size than the size driving plate glue-filling slot 5 of plate 6, directly driving plate 6 is put in driving plate glue-filling slot 5, and by driving plate 6 to be fixedly arranged on the base plate 31 of drain pan 3, then the wiring driving plate 6 is drawn from wiring glue-filling slot 7; When driving when being sized larger than the size driving plate glue-filling slot 5 of plate 6, one or more dividing plates 4 can be taken out according to the size cases driving plate 6, until plate 6 can will be driven to put between two dividing plates 4, then by driving plate 6 to be fixedly arranged on the base plate 31 of drain pan 3, then the wiring driving plate 6 is drawn from wiring glue-filling slot 7.
When needing the safety-increasing epoxy potting driving box to the present invention to carry out encapsulating, first the wiring glue-filling slot 7 on the base plate 31 of drain pan 3 is carried out encapsulating, utilize colloid the wiring driving plate 6 to be sealed; Then, to driving plate glue-filling slot 5 to carry out encapsulating, colloid is utilized to be sealed by driving plate 6; It follows that upper cover 1 and casing 2 are tightly connected, namely complete the production of safety-increasing epoxy potting driving box, so that drive plate 6 and wiring colloid thereof to seal, drive plate 6 and wiring thereof will not produce electric spark, it is achieved that explosion-proof purpose. Plate 6 is driven for small size, drive in plate glue-filling slot 5 owing to it can directly be put in one, therefore, during encapsulating, only the driving plate glue-filling slot 5 being placed with small size driving plate 6 is carried out encapsulating, other vacant driving plate glue-filling slots 5, without encapsulating, therefore can be greatly saved encapsulating cost.
Compared with prior art, the safety-increasing epoxy potting driving box of the present invention is general box body, it is possible to the driving plate 6 of adaptive various sizes, compatible good, need not individually customize box body according to every piece of size driving plate 6, both save box body manufacturing cost, again can the size design of unified driving box. The safety-increasing epoxy potting driving box of the present invention includes driving plate glue-filling slot 5 independent of each other and wiring glue-filling slot 7, it is only necessary to drive the encapsulating thickness of plate glue-filling slot 5 to exceed more than the height 3mm driving plate 6, to meet the requirement of explosion proof of GB/T3836.3; And the encapsulating thickness of wiring glue-filling slot 7 less than the encapsulating thickness driving plate glue-filling slot 5, can both meet requirement of explosion proof, can be greatly saved again encapsulating cost.
