In described left cover and right cover, the inner side at the corresponding position of eyelet or outside or inside and outside both sides are provided with the glue chamber filled in for fluid sealant.
The beneficial effects of the utility model are, wiring board is arranged on sealing wiring board housing can protection circuit plate by the impact of water and aqueous vapor, adopt enclosure body can guarantee wiring board proper heat reduction simultaneously, the effect of aluminium profiles radiating tube more, wiring board is arranged on when left cover or right cover being installed into enclosure body convenient, wiring board can directly be inserted between mounting bracket and bracing frame (can also add securing member as screw), the mounting bracket and the bracing frame that arrange inclined-plane facilitate wiring board to be inserted in circuit board fixing device, radiator fan contributes to the further heat radiation of enclosure body, the wire that being provided with of glue chamber helps be connected with wiring board through and wire seal through using fluid sealant (as sealing resin) to be packed to afterwards, the projection with depression can make wire 360 rotate and can not cause the fracture of wire, therefore the utility model compared with prior art has substantive distinguishing features and progress.
Accompanying drawing explanation
Details and the operation principle of execution mode of the present utility model and embodiment are described below in conjunction with accompanying drawing.
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Fig. 2 is left cover inside structure schematic diagram.
Fig. 3 is left cover end view, structural representation when establishing wiring board to install above.
Fig. 4 is right cover schematic diagram, containing projection sectional structure.
Embodiment
See accompanying drawing, a kind of wiring board housing in present embodiment, comprise left cover 1, right cover 2 and enclosure body 3, it is square or rectangular aluminium profiles radiating tube that present embodiment middle shell body have employed cross section, left and right lid lays respectively at the left and right opening part of enclosure body, aluminium profiles radiating tube lateral wall is provided with protruding heat radiation rib, and radiating effect is better.Flange 10 is respectively equipped with on inside described left cover and right cover, sheathed sealing ring 12 on flange, flange sleeve is located in the opening of enclosure body, sealing ring is between enclosure body inwall and flange, described left cover, right cover and enclosure body form the seal cavity arranged for wiring board, wiring board arranges in seal cavity and (can be arranged in enclosure body, also can be arranged on left and right and cover).The eyelet 9 penetrated for wire when described left cover and right cover being respectively equipped with installation, namely left cover, right cover are provided with eyelet (eyelet here refer to also do not have through), wire can be penetrated eyelet when seated, get through eyelet, very convenient when therefore installing, and eyelet can arrange several, convenient and practical by demand through hole eye.In described left cover and right cover, the inner side at the corresponding position of eyelet 9 or outside or inside and outside both sides are provided with the glue chamber filled in for fluid sealant, glue chamber can adopt circle or square caveli or adopt circular or square barrel mast shape chamber protruding, fluid sealant can be filled in again after wire penetrates to seal, more guarantee the sealing of seal cavity.
The present embodiment middle shell body adopts cross section to be rectangular pipe, and therefore flange forms the shape that matches also is that the flange of rectangular " enclosing wall type " carrys out engagement sleeves and is located in opening, and sealing ring can be arranged between flange and enclosure body.When the wall of enclosure body is thick not, during its insufficient strength, flange be arranged on the structural strength increasing enclosure body in opening, therefore can select when selecting enclosure body the pipe that thickness is less, save cost on the one hand, reduce weight on the other hand, guarantee again its intensity.
In wiring board housing wiring board 5 being arranged on sealing can protection circuit plate by the impact of water and aqueous vapor, dust; adopt enclosure body can guarantee wiring board proper heat reduction simultaneously; the better heat-radiation effect of aluminium profiles radiating tube, the wire that being provided with of glue chamber helps be connected with wiring board through and wire seal through using seal (as sealing resin, fluid sealant) to be packed to afterwards.Left cover and right cover adopts the technique of injection moulding, as rubber injection mold and plastics injection moulding, makes convenient.
The outside of described left cover 1 is the projection 11 that connecting terminal components 8 or confession wire pass through, and the outside of described right cover 2 is the projection 11 that connecting terminal components 8 or confession wire pass through.The intermediate recess of described projection 11 and recess walls is cambered outwards arc.Certainly also can be relative with the described eyelet of medial surface by projection.The projection with depression can make wire 360 rotate and can not cause the fracture of wire.
Described enclosure body is provided with radiator fan 7, increases the heat-sinking capability of enclosure body further.
