The open slot of above-mentioned adapter is divided into the first clamping groove and the second clamping groove, when physical cabling needs upper incoming line When adapter, adapter is with regard to formal dress, i.e., upward, hook is connected in the first card slot for the side of band connection piece, when physical cabling needs When the adapter of lower inlet wire, adapter just downward, link up with and be connected in the second card slot by anti-dress, the i.e. side of band connection piece, this The adapter of sample can meet the requirement of upper and lower inlet wire simultaneously, and product is versatile, by changing the structure of base openings slot come real It is existing, production cost is greatly reduced, and be both provided with independent insulating spacer above each connection sheet, operates staff Shi Buyi electric shock, improves product protective performance.

This practical connection sheet that is further arranged to is in " [" type, connection sheet include evener, the both ends fold of the evener It is respectively formed fixed part and lower fixed part, fixed portion forms U-type groove, and lower fixed part forms circular hole, the lower fixation Portion is fixed on copper bar, and upper fixed part is connected on breaker.

Above-mentioned connection sheet is integrally formed, and guarantees the reliability connected between adapter and breaker, and the " [connection of " type Piece more saves material, reduces production cost.

This practical insulating spacer that is further arranged to includes occlusion part connected vertically and clamping portion, and the occlusion part is parallel The top of upper fixed part is set, and the clamping portion side directed downwardly sequentially forms left elastic plectrum, long shaped plate, right elastic dialing Piece, the end of the left elastic plectrum and the end of right elastic plectrum are respectively formed arc convex, sequentially form three on the slot A square groove, the inwardly protruding formation square of the side wall of two sides square groove, in the square groove that the long shaped plate is connected between, left elastic dialing Piece and right elastic plectrum pass through the mating connection of arc convex and square in the square groove of two sides respectively.

Above-mentioned insulating spacer is independently arranged at the top of respectively upper fixed part, does not influence between each other, and installation side Just, as long as after breaker is mounted on upper fixed part, insulating spacer is injected in slot.

This practical position for being further arranged to cover board face circular hole forms preformed hole, and the surface of the cover board is smooth Shape.

This practical position for being further arranged to cover board face circular hole forms preformed hole, and the surface of the cover board forms a plurality of Padded item disposed in parallel.

Be provided on above-mentioned cover board preformed hole can allow adapter be suitable for copper post wiring breaker, smooth cover board and Cover board with padded item keeps the versatility of adapter stronger to be adapted to the height of different breakers.
