Embodiment
Fig. 1 shows an embodiment form of the earthing screw setting that comprises screw strutting piece 101, the first packing ring 103, the second packing ring 105, the first screw 107 and the second screw 109.In one embodiment, screw 107 and 109 can be rigging screw.
Screw strutting piece 101 comprises first flat components 111 with the first dimple 113 and second flat components 115 with the second dimple 117. Flat components 111 and 115 is engaged flexibly by the attachment 118 that can be U-shaped.
Alternatively, screw strutting piece 101 can comprise the fastening band 123 of stretch out (as from the first flat components 111 extensions).In its end, fastening band 123 comprises the flat components 125 with the dimple for receiving for example trip bolt 127.
Screw strutting piece 101 can be used for the cable lug 129 of earth cable 131 to connect, as is connected to the housing of electric assembly (not illustrating in the drawings).
Fig. 2 a has shown the earthing screw installation and application in Fig. 1 to Fig. 2 c.For example, as shown in Figure 2 a, first packing ring 103 and 105 is inserted in the corresponding dimple 113 and 117 of screw strutting piece 101.Due to the flexibility of the screw strutting piece 101 existing with flexible strip form, packing ring 103 and 105 can be pressed against respectively in corresponding dimple 113 and 117.Then, packing ring 103 and 105 locks in the axial direction by groove 119 and 121.But, in order to allow packing ring 103 and 105 rotate in dimple 113 and 117, not lock washer 103 and 105.After this,, as shown in Fig. 2 b, screw 107 and 109 can be inserted or tightens in packing ring.Fig. 2 c shows the sub-assembly of gained.Or, also can first screw 107,109 be inserted/tighten in packing ring 103,105, then, packing ring 103 and 105 can be pressed/navigated in the corresponding dimple 113,117 of respective planes parts 111,115.
Fig. 3 a is to the earthing screw installation and application of Fig. 3 b exploded view 1.As shown, can fastening band 123 be fixed to the fastening earthing screw strutting piece 101 of base 303 by trip bolt 301 in Fig. 3 a.Or, the hasp (snap) of fastening earthing screw strutting piece 101 can be provided, it can be integrated with chassis (, base 303).Base 303 can possess the machined surface element 305 of base 303 for receiving screw 107 and 109.Surface element 305 can or be made a plate that is attached to housing with the integral formula of base 303.As shown, cable lug 129 can be fastened to Anti-fall sub-assembly 305 with screw 107,109 in Fig. 3 b and Fig. 3 c.Surface element 305 is the electrical contact surfaces for connector lug 129.
Fig. 4 displaying comprises first flat components 403 with the first dimple 405 and the screw strutting piece 401 with the second flat components 407 of the second dimple 409. Flat components 403 and 407 is engaged flexibly by attachment 411, the rigging screw that described attachment 411 can be U-shaped and do not describe in Fig. 4 with fixing through formation.
Alternatively, screw strutting piece 401 can comprise the fastening band 413 of stretch out (as from the first flat components 403).In its end, fastening band 413 comprises having the flat components 415 that can be used for the dimple 417 of receiving (as received holding screw) effect.
Screw strutting piece 401 provides solution with rigging screw, and rigging screw, can be by thin stainless flexible sheets metal parts (as adopted the screw strutting piece 401 of spring steel) fixing after pressing into.Major function is that screw is retained in together, and allows to tighten separately/unscrew.Sufficiently long flexure spring steel bar band can meet this requirement simultaneously, because it is incompressible between screw head and ground connection connector lug.
According to some embodiments, also can be for example, by metal washer (, not threaded) by being pressed on screw.In addition, forming the rubber of screw strutting piece or the shape of metal band can be fabricated to different.In addition, can use two with screwing, for example, 4 screws.
Screw strutting piece 101,401 makes it possible to keep two or more screws in a common part.In addition can be screwed into individually and the screw of back-outing.According to some embodiment forms, screw can by screw strutting piece 101,401 fastening with prevent install and dispose during drop.According to some embodiment forms, the friction that screw head forms respectively and between packing ring 119,121 can not be reversed or rotary screw strutting piece 101 (for example can be formed by rubber strip).
According to some embodiment forms, grounding screw 107 and 109 can be both that two metals (as stainless steel) packing ring 103,105 keeps based on flexible silicon adhesive tape band (as having hole or dimple 113,115 screw strutting pieces 101).。The outside of packing ring can have 360 degree grooves 119,121.Metal washer 103,105 can be installed in silicon strip band 101, and by fixing around the rubber of groove 119,121.Hole 113,115 in rubber should allow respective gasket 103,105 rotations, and can not rotate simultaneously or reverse rubber strip.In the time tightening screw 107,109, the friction between screw head and packing ring can make packing ring rotate together with screw 107,109.
According to some embodiment forms, both can keep together packing ring 103,105 in a common assembling parts, and wherein, screw can be tightened or unscrew to screw individually.In addition, band 123 can use independently screw or " rubber strip in lockhole " solution to be attached to base 303.
According to some embodiment forms, earthing screw 107,109 can be tightened respectively through respective gasket 103,105.Because screw 107,109 can have the shoulder that screw 107,109 is fastened, so in the time that screw 107,109 removes from base 303, screw 107,109 still can maintain by packing ring 103,105.
