Embodiment
The utility model provides a kind of device that is fixedly connected fast.Have quick fixed line, the rapid coupling circuit prevents the circuit wrong plug, has the excellent waterproof dust reduction capability, reaches industry IP65 standard, is convenient to daily installation, R and M.(referring to Fig. 1)
The sketch map of anti-wrong plug three-phase coupling as shown in Figure 3 and anti-wrong plug design thereof.Should prevent that jack and cutting in the three-phase joint unit in the wrong plug three-phase coupling (3) were to be triangularly arranged; One rectangular recess (referring to Fig. 6 and 7) is arranged in the jack of a joint (3-2) therein, go up should in the cutting of jack a rectangle strip projection (referring to Figure 4 and 5) being arranged at another joint (3-1) of correspondence.Have only when rectangle strip projection and align, could two joints be docked with rectangular recess, communication line, otherwise two joints can't dock.The method that is connected and fixed of electric wire and anti-wrong plug three-phase coupling (3); It is the method that common electrician knows; Promptly, will prevent that a screw is unscrewed in the screw hole (4) on the wrong plug three-phase coupling (3), insert the conductor in the electric wire by the straight screwdriver of corresponding size; Tighten fixingly again, can accomplish the connection of electric wire and anti-wrong plug three-phase coupling (3).The anti-wrong plug three-phase coupling (3) of this particular design can prevent effectively that circuit from connecting mistake and causing short circuit to take place.
The utility model is to the water proof and dust proof problem of circuit connection place, designs a two and is threaded the tubular construction with nut in that anti-wrong plug three-phase coupling (3) is outer, plays the effect of water proof and dust proof.This pipe (2) structure comprises inner nut (1), pipe (2), rigid thin packing ring (5), soft thick washer (6) and outer nut (7).(referring to Fig. 2).
This pipe (2) has two helicitic textures; One section smooth prolongation is arranged behind the screw thread, no any prolongation behind another screw thread, and one section groove (8) that is convexed to form by both sides is arranged between two screw threads; When tightening outer nut (7), this groove (8) is convenient to hand stationary pipes (2).In use, on lighting device, need wear the place punching of electric wire in advance, the overall diameter that bore dia and pipe (2) are gone up smooth prolongation pipe is suitable; Two nuts that to manage on (2) unload, and insert lighting device to the screw thread that has smooth prolongation pipe one end of pipe (2), at the medial surface screw-in inner nut (1) of lighting device; Utilize the groove (8) of pipe (2); Stationary pipes (2) is tightened inner nut (1), thereby can this pipe (2) be fixed on the lighting device; Realize sealing effectiveness simultaneously, prevent that from then on extraneous water and dust from getting in the lighting device junction.At this moment, the electric wire in the lighting device can pass from pipe (2), connects with anti-wrong plug three-phase coupling (3).Owing to 2 packing rings are arranged: soft thick washer (6) and rigid thin packing ring (5) in outer nut (7).Soft thick washer (6) one head edges slightly have arc, and a head edge does not have arc.There is arc one end at soft thick washer (6) edge outwardly, and the external cable that will connect passes outer nut (7), soft thick washer (6) and rigid thin packing ring (5) successively; Connect with anti-wrong plug three-phase coupling (3), accomplish circuit and connect, successively soft thick washer (6) and rigid thin packing ring (5) are pushed in the outer nut (7); And outer nut (7) screwed on pipe (2), utilize the groove (8) of pipe (2), stationary pipes (2); Tighten outer nut (7), because the squeezing action of screw socket causes soft thick washer (6) to expand; Endoporus dwindles; Thereby realize fixed line and sealed tube (2) effect, can prevent effectively that extraneous water and dust from getting into pipe (2) from the connection place of outer nut (7), thereby realize the water proof and dust proof effect.Wherein used a rigid thin packing ring (5) here, can the screw socket applied pressure have been disperseed, can more effectively make the stressed expansion of soft thick washer (6).This device is to use waterproof material to make, and through such assembling, the whole device that is fixedly connected fast can reach the IP65 standard.
According to claim, protection range of the present invention comprises and is not limited to the foregoing description.
