Embodiment

Describe preferred implementation of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Fig. 4-7, in the first and optimum execution mode of two glass assemblies of easy chamfered edge of the present utility model, it comprises the first glassy layer 4, the second glassy layer 5, lead-out wire 3, adhesive film 6 and cell piece 7, wherein, lead-out wire 3 bending to the second glassy layer 5 between this first, second

glassy layer

4,5, afterbody are covered on the surface of this second glassy layer 5.Than the structural design of prior art, the similar semi-enclosed design that lead-out wire 3 forms, can on the thickness position of two glass assemblies, reach an effective barrier effect to the glue in gap, thereby glue can only be overflowed to other positions, can effectively prevent that more glue from overflowing to the surface of lead-out wire, cleaning to cull on lead-out wire 3 while facilitating chamfered edge, lead-out wire 3 and the disconnected situation of terminal box avoiding causing because of cull, thus improve the whole efficiency of chamfered edge.

In the second execution mode of two glass assemblies of easy chamfered edge of the present utility model, it is compared with above-mentioned the first execution mode, and difference is: lead-out wire 3 bending to the first glassy layer 4 between this first, second

glassy layer

4,5, afterbody are covered on the surface of this first glassy layer 4.Present embodiment has just been carried out contrary setting by the wrap direction of lead-out wire, and its obtained beneficial effect is identical with the first execution mode.

As shown in Fig. 5-7, in the third execution mode of two glass assemblies of easy chamfered edge of the present utility model, the end position of drawing lead-out wire 3 at it between the first above-mentioned glassy layer 4 and the second glassy layer 5 carries out height and shifts to install, and this lead-out wire 3 is to low side's bending.In the time of situation in the first execution mode, the second glassy layer 5 is lower than the first glassy layer 4, and lead-out wire 3 bends to the second glassy layer 5; When situation in the second execution mode, the first glassy layer 4 is lower than the second glassy layer 5, and lead-out wire 3 bends to the first glassy layer 4.Two glassy layers of high infraversion malposition are set, can make the dogleg section of lead-out wire 3 can keep and the flushing of glassy layer, make it can not protrude from entirety, in the time of chamfered edge, be just not easy to be damaged to like this lead-out wire 3, also can help first and second kinds of execution modes to obtain better implementation result.
