Embodiment
In order to make the technical solution of the utility model clearer, below in conjunction with accompanying drawing, terminal block of the present utility model and air conditioner are described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the schematic diagram of traditional approach terminal block, and Fig. 2 is the schematic diagram of traditional wired martingale terminal.The terminal block 400 of traditional approach adopts a plurality of identical metal inserts 410 and identical binding post 300, binding post 300 is inserted on the metal insert 410 on terminal block 400 by straight cutting or horizontal slotting mode, the identical binding post 300 connecting with difference in functionality different colours wire is easily inserted on wrong metal insert 410, easily breaks down.
Refer to shown in Fig. 3, it is the schematic diagram of the utility model terminal block one embodiment.The utility model terminal block 100 comprises metal insert and insulating base 130, and terminal block 100 is fixed on the mainboard of air conditioner.On insulating base 130, be provided with groove 150, the quantity of groove 150 is identical with the quantity of metal insert.Metal insert is fixed in the corresponding groove 150 of insulating base 130 both sides.
Preferably, at least comprise three pairs of metal inserts on terminal block 100, the shape of every pair of respective metal inserted sheet is identical, and between multipair metal insert, shape is not identical.Metal insert can be sheet metal inserted sheet 120 or cylindrical metal inserted sheet 110.The shape of cylindrical metal inserted sheet 110 can be provided with spacing hole 115 for triangular prism shape, quadrangular shape or cylindric on cylindrical metal inserted sheet 110, on sheet metal inserted sheet 120, be provided with screw, in Fig. 3, on sheet metal inserted sheet 120, in screw, screw is installed.
The quantity of the groove 150 preferably, arranging on insulating base 130 is identical with metal insert 110 quantity on terminal block 100.
Preferably, insulating base 130 medium positions are provided with at least one installing hole 140, by installing hole 140, terminal block 100 are fixed on air conditioner mainboard.While only containing an installing hole, terminal block 100 may rotate around the screw fixing, and produces unnecessary negative effect.When installing hole 140 is two, terminal block 100 fixing meeting on air conditioner mainboard is more firm.
Preferably, as shown in Figure 4, be the schematic diagram of binding post one embodiment of the utility model terminal block, binding post 200 is open column shape binding post, open column shape binding post 200 be shaped as triangular prism shape, quadrangular shape or cylindric.On open column shape binding post 200, be provided with projection 210; Projection 210 is arranged on the inner ring of open column shape structure of described body.
As shown in Figure 2, be the schematic diagram of traditional wired martingale terminal, binding post 300 is " U " shape sheet binding post; On " U " shape sheet binding post 300, be provided with breach 310, breach 310 is arranged on described " U " shape binding post front center position.
As shown in Figure 3, during installation, " U " shape binding post 300 breach 310 plug together with sheet metal inserted sheet 120 of the present utility model, by screw, " U " shape binding post 300 and sheet metal inserted sheet 120 is fixing tight, prevent that " U " shape binding post 300 from coming off.
Preferably, as a kind of embodiment, during installation, after the metal insert of open column shape binding post 200 and correspondingly-shaped plugs together, the projection 210 arranging on open column shape binding post 200 inner rings engages with the spacing hole 115 on metal insert, prevent that binding post 200 from dropping, and Stability Analysis of Structures, convenient disassembly.
Preferably, the quantity of open column shape binding post 200 is corresponding with quantity and the shape of cylindrical metal inserted sheet 110 with shape, and the open column shape binding post 200 of every kind of shape can only plug together with the cylindrical metal inserted sheet 110 of correspondingly-shaped.Guaranteed that binding post 200 and metal insert, to slotting uniqueness, have foolproof function, stopped the possibility of binding post 200 wrong plugs completely.
Terminal block of the present utility model and binding post can be applied on air conditioner, and terminal block 100 quantity of installing on air conditioner are more than or equal to 1.
Above-mentioned air conditioner, between plate, during wiring, one end of wire is welded on the mainboard of air conditioner, and the other end of wire connects binding post 200.The wire of difference in functionality different colours connects respectively the binding post 200 of correspondingly-shaped, then by binding post 200, is connected on the metal insert of correspondingly-shaped.
When inside and outside machine line, in multicore cable, the two ends of every heart yearn connect identical shaped binding post 200, and the binding post 200 at every heart yearn two ends of multicore cable is connected with the metal insert of correspondingly-shaped on terminal block 100.
Terminal block of the present utility model and binding post, a kind of corresponding binding post that connects same shape of wire of function color, a kind of metal insert of the corresponding a kind of shape of binding post of shape, by shape, metal insert and binding post are limited, there is foolproof function, guarantee the uniqueness of metal insert on binding post and terminal block, fundamentally stopped the possibility of metal insert wrong plug on binding post and terminal block.Improve the installation quality of air conditioner simultaneously, reduced production, failure rate after sale.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
