The board-like connecting terminal block of a kind of combined bilayer
Technical field
The utility model relates to a kind of electric auxiliary product, especially a kind of combined type plate type connecting terminal block that is used to be electrically connected.
Background technology
In fields such as electric power, traffic, building and industrial automations, board-like connecting terminal block has obtained utilization more and more widely because wiring is directly perceived, simple in structure, connect advantages such as reliable.But because existing board-like connecting terminal block is single layer structure mostly at present, be unfavorable for improving space availability ratio, and the double-deck board-like connecting terminal block of present only minute quantity, its upper and lower layer can not be realized intercommunication again, adjacent two connecting terminal blocks can not be realized interconnected, can not satisfy into three and go out and user demand that the sheet sheet is interconnected.
Summary of the invention
In order to solve the prior art above shortcomings, the utility model proposes the board-like connecting terminal block of a kind of combined bilayer, this combined connecting terminal block adopts the board-like mode of connection, be provided with, following two-layer wiring construction, by insulating part, screw, the integral type conducting strip of pad and levels UNICOM is formed, the planform of integral type conducting strip adopts " up and down, this board-like connecting terminal block has realized that one advances three connection functions that go out, also can offer the contact window in the upper strata or the lower floor of insulating part, realize the interconnected of adjacent two connecting terminal blocks, this board-like connecting terminal block economical with materials, the space availability ratio height, simple in structure, cost is low.
The utility model solves its technical problem, the technical scheme that is adopted is: the board-like connecting terminal block of a kind of combined bilayer, be made up of the integral type conducting strip that insulating part, screw, pad and levels communicate, its design feature is: the upper and lower layer at the board-like connecting terminal block of bilayer is provided with the integral type conducting strip of intercommunication up and down.
The conducting strip of integral type up and down in the double-deck board-like connecting terminal block of combinations thereof type, its planform adopts ".
The double-deck board-like connecting terminal block of combinations thereof type can also be provided with the contact window in the upper strata or the lower floor of insulating part.
Compared with prior art, the beneficial effects of the utility model are: adopt the integral type conducting strip of UNICOM up and down to realize the connection function of double-deck intercommunication in the board-like connecting terminal block of combined bilayer, the connection function of the not intercommunication of bilayer that realizes of the split type conducting strip of UNICOM not up and down that replaces that prior art adopts.The characteristics of double-deck intercommunication are to realize that one advances three connection functions that go out; Prior art adopt up and down not the split type conducting strip of UNICOM can not realize that then one advances three connection functions that go out.
The integral type conducting strip of the UNICOM up and down that is provided with in the utility model adopts the " structure, and the characteristics of " structure are: electrical conductivity is good, processing technology is good, stock utilization is high.
The utility model also can be directly offered the contact window in the upper strata or the lower floor of the board-like connecting terminal block insulating part of bilayer, be characterized in to realize the interconnected of multi-disc connecting terminal block, satisfy the user demand of adjacent connecting terminal block requirement intercommunication, prior art then can not be offered the contact window on insulating part.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the perspective view of the utility model basic structure;
Fig. 2 is the schematic perspective view of the conducting strip of integral type up and down in the utility model;
Fig. 3 is the utility model is offered the contact window respectively at the upper and lower layer of insulating part a perspective view.
Embodiment
As shown in Figure 1 and Figure 2, first kind of embodiment of the present utility model is: the board-like connecting terminal block of a kind of combined bilayer, by insulating part 1, screw 2, pad 3 and up and down the integral type conducting strip 4 of two-layer UNICOM form.Insulating part 1 and conducting strip 4 all are arranged to the stairstepping misconstruction on thickness direction.The utility model is owing to being provided with the integral type conducting strip 4 of UNICOM up and down, so can realize easily that one advances the three separated time functions that go out.Because insulating part 1 and conducting strip 4 adopt the stairstepping misconstruction, can not stop the operation of screwdriver simultaneously, guarantee the enough operating spaces of lower floor's connector assembly lower floor's screw so be connected on the lead at screw place, upper strata.
As shown in Figure 3, second kind of embodiment of the present utility model is: on the basis of Fig. 1, upper strata or lower floor at insulating part 1 offer contact window U, by this contact window, use plate to satisfy the wiring demand of the interconnected use of multi-disc connecting terminal block needs directly with the circuit UNICOM of two adjacent connecting terminal blocks.Obviously, this contact window U both can be opened in the left side of insulating part 1, also can be opened in the right of insulating part 1; Both can be opened in the upper strata of insulating part 1, also can be opened in the lower floor of insulation 1; Can also all offer at the upper and lower layer of insulating part 1.
