Description
Technical field
The present invention relates to a kind of connector, a kind of main circuit switch being applicable to low-voltage distribution cabinet unit drawer, belong to low-voltage electrical apparatus design and fabrication technology field.
Background technology
In low-voltage distribution cabinet, the main circuit switch of unit drawer is made up of the dynamic connector cooperated and quiet connector.When specifically used, main circuit switch is moved connector by two groups and quiet connector forms, and one of which connects as inlet wire, and another group connects as outlet.Quiet connector is fixed on the rear bulkhead of low-voltage distribution cabinet motionless, on it, A, B, C three-phase connector assembly is be bi-directionally connected, connector assembly one end is connected with dynamic connector, and the reserved connecting hole on connector assembly other end copper bar corresponding with the related circuit in power distribution cabinet connects；Dynamic connector, is arranged in the back plate of unit drawer, and along with the pull of unit drawer moves together, A, B, C three-phase connector assembly thereon is be bi-directionally connected.Electrical equipments in the connector assembly terminals of dynamic connector connected for inlet wire and unit drawer etc. connect, and the other end of connector assembly is connected the inlet wire part as unit drawer loop with external power source such as bus etc.；Electrical equipment etc. in the one end of connector assembly of the dynamic connector connected for outlet and unit drawer connects, and the other end and quiet connector are attached the outgoing line part as unit drawer loop.After dynamic connector realizes socket connection along with motion and the quiet connector of drawer, inlet wire dynamic connector and bus external power supply being connected, outlet dynamic connector and quiet connector connect, just achieve unit drawer and loop between power distribution cabinet connection.
Owing to the main circuit switch of unit drawer uses the mode of push-and-pull to realize dynamic connector and the connection of quiet connector and disconnection in use, owing to drawer backboard has certain elasticity, during the patching of push and pull unavoidable because such elastic conducting activate between connector and quiet connector patch insecure.Therefore dynamic connector is arranged on the bottom of low-voltage distribution cabinet unit drawer to utilize the rigidity of unit drawer base plate to reduce the impact on connector stability of the elasticity of drawer backboard.Thus, the universal understanding of those skilled in the art is thought, it is the best that the nearest with the distance of unit drawer base plate and connector the lowest its of whole height of connector patches stability.Therefore to reduce thrust and the pulling force impact on connector stability, connector is all set to the structure of the yi word pattern that A, B, C three-phase is transversely arranged or A, B, C, N tetra-is mutually transversely arranged to reduce the whole height of connector by technical staff.
Owing to the standard size of China's drawout cubicle width is 600mm, the back plate of drawer unit a size of about 510mm, need two transversely arranged three-phases or four phase connectors are installed in drawout cubicle, therefore the phase spacing of connector is just proposed certain requirement.Phase spacing general in industry is fixed as 50mm, the terminals of dynamic connector use riveting line to connect, electrical distance requirement can be met, but the structure that riveting line connects is moved connector terminals and is structure as a whole with inserted sheet end, the wire connect along with electric current increasing is thicker, in wiring process by the unit drawer degree of depth limited radius of curvature too small cause wire distortion drive inserted sheet end offset, make inserted sheet end unbalance stress that monolateral situation about patching occur the when of patching, inserted sheet end virtual connection part contact resistance increases, Contact Temperature raises, the reliability that impact patches, bring potential safety hazard.When the terminals of dynamic connector use the bolt mode of connection, and its terminals and inserted sheet are that the activity surplus that can ensure that inserted sheet end of split is not affected by terminals, patch safety and reliability.Therefore, when the switch of below 400A connects, phase spacing is that 50mm can meet electrical safety insulation distance.And if when the switch being applied to more than 400A connects, the phase spacing of 50mm is it is difficult to ensure that electric safe insulation distance.
To this end, prior art proposes use the main circuit switch of bolt wiring to avoid riveting line to connect the monolateral situation about patching caused.If but use the mode of bolt wiring, the length of bolt is relevant to wire thickness, if the least requirement that cannot meet creep age distance (along the beeline on insulant surface between two current-carrying parts) of distance between the connection bolt that phase spacing is 50mm, A phase and B phase connector assembly.And if arranging phase spacing is 60mm, the distance between connecting bolt and adjacent phase connector assembly is made to meet safe insulation distance, just cause connector yardstick excessive, when particularly needing to install two plug connectors in a unit drawer, in the back plate of unit drawer, its yardstick of transversely arranged installation has breached the size of the most general cabinet.Comprehensively reequip unless put into substantial amounts of fund at the cabinet used with user, otherwise can not popularization and application.
The improved method of the main circuit switch of the bolt wiring used at present is the size according to general cabinet, uses the phase spacing of 55mm, increases the insulating elements such as insulation board the most between the two phases, prevents phase spacing from the most closely causing creepage accident.
A kind of plug-in unit of complete switch drawer as disclosed in existing patent documentation CN202142804U, as depicted in figs. 1 and 2, including plug connector B1, bolt B 2, cable B3, insulating barrier B4, conductive plate B5, conducting strip B6, wherein the current-carrying part of plug connector B1 is more sheets of conductive sheet B6 composition, the number of conducting strip B6 quantity is determined by the size of electric current, one of conducting strip B6 is inserted directly on bus, other end directly leads out through conductive plate B5, then punching on conductive plate B5, effectively connected by connecting bolt B2 and cable B3, plug connector B1 connects insulation board B4, prevent phase spacing from the most closely causing the accidents such as creepage.The mode that the program just have employed at alternate increase insulation board avoids creepage accident, but owing to phase spacing is the least, connecting bolt B2 and cable B3 operates very inconvenient when effectively connecting, the especially connection to B phase, B-phase is between A phase and C phase, the space on both sides is the narrowest and small, is not easy to very much the operation of wiring.If adding insulation board between the two phases, the further of working place causing connecting bolt B2 to be effectively connected with cable B3 reduces, and be unfavorable between connecting bolt B2 with cable B3 is effectively connected.On the other hand, such narrow space also further limit the length of connecting bolt B2, and when especially needing the number of cables connected increased, the restriction of working place and connecting bolt length brings difficulty all to effective connecting bolt and cable.The connection of insulation board B4 and connector simultaneously is not to be securely fixed connection, easily drops and lose in using, it is impossible to ensure to continue reliably to provide safe insulation isolation.
In sum, the connector of yi word pattern structure is affected by phase spacing, cause adjacent biphase between space the least, be not easy between connecting bolt and cable is reliably connected；Increase insulation board the most between the two phases to make troubles further to effective connection of connecting bolt and cable again.But those skilled in the art all think the bottom of connector unit drawer to be arranged on, the closer to the lowest stability that the most more can guarantee that connector of the base plate of unit drawer and the whole height of connector.Therefore in prior art, technical staff generally believes that connector can only be set to yi word pattern structure could meet the requirement of stability.To sum up, how to be given and a kind of can meet international standard to the requirement of phase spacing, can facilitate being reliably connected between connecting bolt and cable again simultaneously, the connector simultaneously meeting stability becomes the difficult problem of puzzlement those skilled in the art.
In sum, the connector of yi word pattern structure is difficult in the case of adapting to existing unit drawer size meet the international standard requirement to phase spacing, and increases insulation board between the two phases and can make troubles to connecting bolt and effectively connecting of cable.How to be given a kind of can meet simultaneously the phase spacing in unit drawer dimensional requirement, international standard require and can meet be stably connected with reliable connector become puzzlement those skilled in the art a difficult problem.
And applicant is finding through long-term exploratory development, the position of low-voltage distribution cabinet unit drawer back plate generation elastic deformation impact is mainly in the top position, middle part of back plate, and due to the impact of drawer side, also has same rigidity in drawer backboard both sides.Proposing to improve the yi word pattern arrangement form of connector on this basis, docking plugs steady qualitative and connection reliability and does not has influential, fully meets a kind of main circuit connector for unit drawer of low-voltage switch box of requirement.
It addition, in order to prevent from foreign body from dropping on connector causing the unnecessary potential safety hazards such as short circuit, generally to add an insulating boot in the outside of quiet connector, this insulating boot also takes on and alternate is dielectrically separated from effect simultaneously.Existing yi word pattern connector and insulating boot are to carry out installing by the form of buckle being connected, and as shown in Figure 3 and Figure 4, Fig. 3 gives the top view of connector in prior art, and it adjacent two alternate is provided with draw-in groove B72；Shown in Fig. 4 for insulating boot of the prior art, be provided with the fastener B71 matched with draw-in groove B72, fastener B71 be inserted in draw-in groove B72 and realize insulating boot B7 is fixed.Adopting and be fixed insulating boot in this way, and insecure, insulating boot B7 easily comes off loss, thus cannot continue play protective action reliably and be dielectrically separated from effect, causes the unnecessary potential safety hazards such as short circuit.
