Shell
As shown in figure 5, described shell 4 is " Qian " shape groove, including end plate mounting rail 41 and the chute axially through shell 4 42;The end plate mounting rail 41 is separately positioned on the symmetrical position of the inwall of shell 4 and the centre position of the lower wall of shell 4, and End plate mounting rail 41 is axially through shell 4;Universal contact receptacle module 8, GB-10A sockets module 9, IEC-C13 sockets module 10, IEC-C19 sockets module 11, SPD modules 12, monitoring module 13, double-break switch 14 and breaker 15 are slipped into by chute 42 respectively It is fixedly mounted in " Qian " the shape groove of shell 4.
Fig. 5, shell 4 described in 21 to 23 left and right inwall upper surface, also including the breach 43 for axially penetrating through shell 4, under End face left and right edges respectively symmetrically provided with the groove 44 axially penetrated through, line winder 5 is separately fixed at outer by breach 43 and groove 44 On the right outer surfaces of shell 4, lower position is respectively equipped with fixed installation neck 45 below the center line of two side external surfaces of shell 4.
Two axial ends of the end plate mounting rail 41 are provided with tapping screw mounting hole, and inlet wire installs end plate 2 and inlet wire Insulating end plate 3 is arranged on one end on the axial end of end plate mounting rail 41 by tapping screw.
Module
As shown in figure 1, bus-PE 16, bus-L17 and bus-N18 are by universal contact receptacle module 8, GB-10A socket modules 9th, IEC-C13 sockets module 10, IEC-C19 sockets module 11, SPD modules 12, the fiery double-break switch 14 of monitoring module 13, zero and disconnected Road device 15 is linked up.
Universal contact receptacle module 8, GB-10A sockets module 9 described in this scheme, IEC-C13 sockets module 10, IEC- The structure of C19 sockets module 11 is substantially identical, all including the upper lid 91 and lower cover 95 that mutually fasten and its is installed on upper and lower Three shell fragments in lid.The jack openings in upper lid 91 are distinguished, the mounting structure of each shell fragment in it, the latch of shell fragment and plug connects Tactile position, and the corresponding construction of lower cover can do local directed complete set as needed.
By taking GB-10A modules 9 as an example, as shown in Fig. 2,3 and 4, the GB-10A sockets module 9 includes upper lid 91, PE shell fragments 92nd, N shell fragments 93, L shell fragments 94 and lower cover 95;The edge of the upper lid 91 is provided with raised bayonet lock 911, the raised bayonet lock 911 with Chute 42 is engaged;GB-10A sockets module 9 also includes annular wiring hole 913, L wire clamping connecteds hole 914, PE wire clamping connecteds hole 915 and N wire clamping connecteds hole 916;PE shell fragments 92, N shell fragments 93, the correspondence position of the upper lid 91 of the insertion of L shell fragments 94;Described PE shell fragments 92nd, N shell fragments 93, L shell fragments 94 are connected by respective connecting portion with respective " u "-shaped neck A respectively, the bus-PE 16, Bus-L17 and bus-N18 pass through corresponding PE wire clamping connecteds hole 915, L wire clamping connecteds hole 914 and N respectively in the form of straight line Wire clamping connected hole 916, typical " u "-shaped neck A is diagonally arranged in the inside of GB-10A modules 9, is made between each " U " neck Away from big as far as possible, to avoid shell fragment short-circuit because of the mutual contact of outer force deformation phase, and puncture air when meeting with instantaneous pressure Produce electric arc, and can also safety accurately alignd respectively with corresponding wire clamping connected hole;Lower cover 95 also includes fore-set 951 With three buckles 952, the fixing port 912 of buckle 952 and upper lid coordinates.After lower cover 95 is arranged on upper lid 91, the fore-set 951 PE shell fragments 92, N shell fragments 93, the proper site of the shell fragment of L shell fragments 94 are withstood, the proper site is generally connecting portion, installs it It is more firm;The triangularity of buckle 952 arrangement;Lower cover 95 can be changed freely according to load current size requirements, no The change that same lower cover 95 has turns to the height difference of wire clamping connected hole regulating block 953, and wire clamping connected hole regulating block 953 is higher, wire Blocked hole is smaller, and number of conductors is less and/or the electric current that can load is also just smaller;Conversely, as the same.Two annular wiring holes 913 can be respectively arranged bus-L17 and bus-N18, realize annular distribution.
Described bus-PE 16, bus-L17 and bus-N18 is connected to correspondence by the connection of fast ram plug-in " in U " shape necks A, the connection of fast ram plug-in is to rush bus-PE 16, bus-L17 and bus-N18 by high pressure Wire body is quickly caught in " u "-shaped neck A by bed in the way of punching press.
It is described " U " shape necks A may include the neck of multiple width, general neck width can be set to be used for section 2.5mm2With section 4mm2Wire simultaneously clamping.It is the fast ram plug-in connection low-resistance of this programme, reliability, lasting, stably, Temperature rise is small, eliminates risk on fire;Energized conductor whole process is closed in insulation crust body by fixation, electrical contact point, is eliminated short The electrical safety hidden danger such as road, contact oxidation;Inner annular distribution can be achieved, eliminates Single Point of Faliure and has a power failure, reduces multipoint fault and stops Electric scope;Bus is whole without disconnected node, is connected firmly, node is clean.When avoiding using soldering or self-tapping screw connection, because of three Mingzhi's effect, electric stress and thermal stress effects cause the problem of temperature rise has risk on fire;Improve distribution reliability.
