The invention relates to the technical field of optical fiber access, in particular to an optical splitter no-jumper-connection distribution box and a wiring method thereof. The optical splitter no-jumper-connection distribution box structurally comprises a box body, wherein a wiring board is arranged on a top plate at the top inside the box body; a box-type optical divider fixing module is arranged on a right side plate in the box body; a right guide rail plate bracket is arranged on a right side plate in the box body; a right slide rail plate is arranged on the right guide rail plate bracket; a baseplate mounting plate is arranged at the lower part in the box body; a left slide rail plate is arranged between the top plate and the baseplate mounting plate; a 12-core fused and matched integrated module is erected between the left guide rail plate and the right guide rail; a wire management ring bracket is arranged on the left side of the left guide rail plate; wire management rings are arranged on the wire management ring bracket; a baseplate is arranged below the baseplate mounting plate inside the box body; and a ground plate is arranged on the baseplate, and is provided with optical cable stripping devices. The optical splitter no-jumper-connection distribution box and the wiring method thereof can realize the maximum capacity of wiring for optical cables; an optical fiber circuit can be distinct and clear, without winding; and an optical network signal route can be randomly exchanged, and the routine maintenance is facilitated.

An ultra-wideband has an elongated grounding plate disposed horizontally with a long front edge defined thereon. A connecting portion extends upwards from an end of the front edge. A first antenna radiator includes a first radiating strip extended from a side of the connecting portion and a second radiating strip connecting with a free end of the first radiating strip. A third antenna radiator includes a third radiating strip suspended over the grounding plate, a fourth radiating strip connecting with an end of a long front edge of the third radiating strip and an upper side of the second radiating strip, a fifth radiating strip extended downwards from the long front edge of the third radiating strip connecting with the connecting portion. A third antenna radiator extends downwards from a middle of the long front edge of the third radiating strip. A feeding point disposes on the second radiating strip.

The invention discloses a reflection-free coplanar waveguide band-stop filter and relates to a filter. The band-stop filter comprises a dielectric substrate (1), a metal layer (11), a coplanar waveguide (2) and a plurality of resonant slot rings (3), wherein the coplanar waveguide (2) is located on the metal layer (11) at one side of the dielectric substrate (1); on grounding plates (22) of the coplanar waveguide (2), the plurality of resonant slot rings (3) form absorption regions (4); the central frequency of a stop band of the filter can be adjusted through changing the resonant frequency of the resonant slot rings (3); and the space (31), parallel to the transmission direction of the coplanar waveguide (2), between the adjacent resonant slot rings (3) is greater than the outer diameterof an outer slot strip ring of each resonant slot ring (3) to avoid transmission of energy in the absorption regions (4) along the transmission direction of the coplanar waveguide (2). The band-stopfilter is capable of absorbing a band-stop signal and reducing the standing wave of the stop band, thereby improving the performance of a system.

The invention discloses a hoisting mechanism for detecting mine electromechanical equipment. The hoisting mechanism comprises a bearing plate and side plates, sliding grooves are formed in the two sides of the upper surface of the bearing plate, and sliding blocks matched with the sliding grooves are fixedly installed on the two sides of the lower surfaces of the side plates. According to the hoisting mechanism for detecting the mine electromechanical equipment, through the arrangement of the bearing plate, the side plates, adjusting rods, binding belts and an anti-skid touch ground plate, when the hoisting mechanism is used, by rotating a hand rocker, the anti-skid touch ground plate is in close contact with the ground, the situation that the bearing plate moves in the equipment loading process is avoided, after the equipment is placed on the bearing plate, the side plates are pushed to be in close contact with the side face of the equipment, the positions of the side plates are fixedthrough fixing bolts, meanwhile, the lengths of the adjusting rods are fixed through fixing knobs, after fixing of the side face is completed, the front face of the equipment is fixed through the binding belts, the mechanism can be flexibly adjusted according to the size of the equipment through cooperative use of the parts, the equipment can be well fixed, and the applicability is high.
