Description
Technical field
The utility model relates to a kind of patchboard, and particularly a kind of explosion-proof type YE is with plug-in type sunflower patchboard.
Background technology
At present the explosion-proof type YE (turn round more actuator, angle stroke actuator, Direct Travel actuator,
Pendulum stroke actuator) wiring place, Coal Chemical Industry industry appliance wiring place, coal electricity or nuclear power industry appliance wiring place etc.; Though nominally the requirement of IP68 is satisfied in design; But actual can not prolonged application in submerged type appliance wiring place, butted line lid inlet wire screwed pipe is done except the situation of special processing.
For terminals two kinds of ways are arranged usually in the YE industry at present: a kind of operating space of way
Greatly, wiring is directly perceived, convenient, but binding post quantity few (only 15), no explosive-proof protector measure; Some pipeline flows that automation control is had relatively high expectations are controlled in the process system, and acquired signal generally requires more, adds the requirement of command signal, feedback signal and middle control cabinet or Central Control Room, and this way obviously can not satisfy.
But binding post quantity more (totally 28), maintenance side are carried out in another kind of way wiring operation strange land
Just; But the explosion-proof faying face processing between actuator and the link cover of FIG is difficulty; Can not satisfy the GB3836.2-2000 requirement of explosion proof thereby at some industries that explosion-proof performance is had relatively high expectations (like coal, mining, petrochemical industry, nuclear power or the like); All can not use, seriously limit the scope of application of such actuator product.
Summary of the invention
Be technical deficiency more than solving, the utility model provides a kind of and has had explosion-proof performance, compact to design, the explosion-proof type YE that can insert more binding post with plug-in type sunflower patchboard.
The utility model is realized through following measure:
A kind of explosion-proof type YE of the utility model is with plug-in type sunflower patchboard; Comprise circular internal wiring dish and the external drum that can be interlocked with the internal wiring dish; Said external drum inward flange is that the annular step scalariform is protruding; The center is an annular step scalariform groove in the external drum; The convexity in the external drum and the ladder end face of groove are provided with outward extending plug jacket, are provided with annular step scalariform groove and the convexity that matches with external drum in the said internal wiring dish, and the convexity in the internal wiring dish and the ladder end face of groove are provided with the outward extending binding post that matches with plug jacket.
The ladder end face of the annular step scalariform groove at center is provided with four power line plug jackets in the above-mentioned external drum; The protruding ladder end face of external drum inward flange annular step scalariform is provided with 32 signal wire connecting sheaths, is correspondingly provided with four power line binding posts and 32 holding wire binding posts on the internal wiring dish.
Annular step scalariform raised brim in the above-mentioned external drum evenly is provided with four V-shaped grooves to the central axis direction depression, and it is protruding that the annular step scalariform recess edge of said internal wiring dish is provided with the V-arrangement that matches with V-shaped groove.
The beneficial effect of the utility model is:
Terminal block, maintenance, easy to maintenance, the binding post quantity of access is more, satisfy the needs of functions of the equipments upgrading pair of wire connection terminals aspect, and explosion-proof performance is higher, has enlarged the scope of application of actuator product.

Among the figure: 1 casing, 2O type circle, 3 jump rings, 4 screws, 5 power line binding posts, 6 holding wire binding posts, 7 internal wiring dishes, 8 external drums, 9 power line plug jackets, 10 signal wire connecting sheaths, 11 guide fingers, 12V shape groove, 13 link cover of FIG, 14 O type circle pads.
Embodiment
Like Fig. 1,2,3,4, shown in 5; A kind of explosion-proof type YE of the utility model is with plug-in type sunflower patchboard; Comprise circular internal wiring dish 7 and the external drum 8 that can be interlocked with internal wiring dish 7; External drum 8 inward flanges are that the annular step scalariform is protruding, and the center is an annular step scalariform groove in the external drum 8, and the convexity in the external drum 8 and the ladder end face of groove are provided with outward extending plug jacket; Be provided with the annular step scalariform groove and the convexity that match with external drum 8 in the internal wiring dish 7, the convexity in the internal wiring dish 7 and the ladder end face of groove are provided with the outward extending binding post that matches with plug jacket.
The ladder end face of the annular step scalariform groove at center is provided with four power line plug jackets 9 in the external drum 8; The protruding ladder end face of external drum 8 inward flange annular step scalariforms is provided with 32 signal wire connecting sheaths 10, is correspondingly provided with four power line binding posts 5 and 32 holding wire binding posts 6 on the internal wiring dish 7.The binding post material is a brass, and internal wiring dish 7 adopts material polyurethane with external drum 8.
During assembling; In advance that actuator is inner binding post is connected between securing member group and the power line binding post 5; Or be connected between securing member group and the holding wire binding post 6, O type circle 2 is loaded onto, again will long fairlead align with pin on being assemblied in casing 1; Cylindrical along manufactured internal wiring dish 7 is pressed in the casing 1, screw 4 cylindricals is coated fluid sealant be screwed into the fairlead outer end; Pressing jump ring 3 at last gets final product.Because it is longer that fairlead cooperates with pin, the cylindrical of internal wiring dish 7 is long and cooperation is tighter, so can realize actuator back panel wiring and extraneous absolute isolation.Dismantle also easily, pull down jump ring 3 earlier, be screwed into and be embedded on the internal wiring dish 7 RC screw thread steel parts and can pull out with tearing pincers open again.Mating surface is little than length and gap between link cover of FIG 13 and the casing 1, adds and loads onto O type circle pad 14, realizes the isolation of link cover of FIG 13 inside and outside gases, with 4 securing member groups inside and outside sunflower dish is compressed at last.
Earlier power line plug jacket 9 is installed in the external drum 8 with plug-in unit holding screw M4, signal wire connecting sheath 10 and plug-in unit holding screw M3 during assembling; To be embedded in wherein 4 fairleads again aligns the guide finger 11 that is assemblied on the link cover of FIG 13 and is pressed into; Fastening with 4 securing member groups at last, accomplish assembly.
More for satisfying connector, adopted pyramid-like structure in the mold design, eight directions adopt slide block to loose core simultaneously, adopt the back die sinking of loosing core earlier during die sinking, guarantee the safe, quick and efficient of mould.Claim " eight to loose core, successive die sinking "
Annular step scalariform raised brim in the external drum 8 evenly is provided with four V-shaped grooves 12 to the central axis direction depression, and it is protruding that the annular step scalariform recess edge of said internal wiring dish 7 is provided with the V-arrangement that matches with V-shaped groove 12.V-shaped groove is done guiding, aligns basically so can guarantee the position of 36 connectors.Because of the V-type face longer, so claim " long guiding, self-centering " again.
The sealing experiment data:
Testing equipment: hydraulic test bench, kerosene pump, experimental condition: after sealing around the actuator casing, fill kerosene, be forced into 1.0MPa, pressurize was checked left end shown in Figure 4 after 30 minutes, no kerosene leaks vestige.
The dielectric voltage withstand experimental data:
Testing equipment: MS2670E pressure-resistant tester
Experiment conclusion: the design meets following standard-required:
GB 3836.1-2010 explosive atmosphere part 1: Device-General requirement;
GB 3836.2-2010 explosive atmosphere part 2: by the equipment of flameproof enclosure " d " protection;
