Embodiment

First sight is shown in Figure 1, disclose the three-dimensional exploded view of the utility model preferred embodiment, and cooperate Fig. 5 that the corner connection device 10 of the utility model embedding group solar panels with framework is described, be connected between two adjacent strip frames 4 in an end angle 401 of this framework 40, the 4a, comprise a corner connector 1 and a sheath 2 that is the L shape; Described

frame

4,4a are made by metal material (lifting as aluminium, iron or copper), and along rectangular solar panels 3 periphery arrangement windings, and make this framework 40 rectangular, the position of described frame 4, these solar panels 3 peripheries of 4a contacts side surfaces is formed with lower floor's passage 41 of being parallel to each other and embedding group solar panels with upper strata slot 43, this passage 41 extends to

bar frame

4,4a both-end, and form a slot 42 respectively in

bar frame

4,4a both-end side, this slot 43 also extends to

bar frame

4,4a both-end, and forms a port 44 respectively in

bar frame

4,4a both-end side.This corner connector 1 both-end prolongs system towards described frame 4, the distolateral direction of 4a respectively and forms a winding arm 11 (cooperating Fig. 6, Fig. 8 and shown in Figure 10), these winding arm 11 terminal ratchet parts 111 that form, can be inserted in described frame 4, the 4a distolateral slot 42 and passage 41, and be fastened in this slot 42 and passage 41 inwalls by this ratchet part 111, distolateral with fixed angles fitting 1 in described

frame

4,4a, and this corner connector 1 has a bending end 13, and one extends to card ditch 12 (cooperating shown in Figure 7) on the described winding arm 11 along this bending end 13.

This sheath 2 can (be lifted as aluminium by metal material, iron or copper) make, and this sheath 2 can rectangular (as shown in Figures 1 to 4), having two can paste and touch described frame 4, the adjacent bond face 21 that 4a is distolateral, 22, described composition surface 21, can be rectangular between 22, and described composition surface 21, form a upper embedded groove 23 in the sheath 2 between 22 respectively and reach caulking groove 24, separately via described

composition surface

21,22 openings, this upper embedded groove 23 can be for an end angle 31 embedding groups (cooperating Fig. 7 and shown in Figure 9) of these solar panels 3, this time caulking groove 24 can supply these bending end 13 embedding groups, and the integrally formed implantable otic placode 25 of ditch 12 interior also embedding groups in described slot 42 that should block (cooperates Fig. 5 in this time caulking groove 24, Fig. 6, Fig. 8, Figure 10, Figure 11, Figure 12 and shown in Figure 13), this otic placode 25 can be V-shape in fact, and have one first side 251 and one second side 252, this first side 251 and second side 252 can be implanted respectively in the card ditch 12 of winding arm 11 of this corner connector 1 both-end, and the otic placode 25 end limits between this first side 251 and second side 252 form an arc groove 253 (as shown in figure 10), be positioned at described adjacent strip frame 4, on the angle of 4a, to avoid the end angle 31 of otic placode 25 shield lights irradiation solar panels 3; So, this sheath 2 can this corner connector 1 of embedding group and this solar panels 3.

In addition, described sheath 2 has an extrados 26 (extremely shown in Figure 6 as Fig. 1), is symmetrical in described

composition surface

21,22, and makes this extrados 26 be positioned at the corner of this framework 40; But the top of described caulking groove 24 down or bottom interior wall are formed with the

grab

27,28 that this bending end 13 of some backstops breaks away from respectively, and described

grab

27,28 can embed for the bending end 13 of this corner connector 1 just to the distance of following caulking groove 24 side inwalls; In this enforcement, prolong system towards the below in the top inner wall of described down caulking groove 24 and form a grab 27, and prolong system towards the top in the described bottom interior wall of caulking groove 24 down and form another grab 28, by to locate this corner connector 1 in caulking groove 24 down.

In addition, described sheath 2 also can be made (as shown in Figures 1 to 4) by plastic material, causes sheath 2 to possess elasticity companding ability; So, when this bending end 13 embeds this time caulking groove 24, can push described

grab

27,28 via bending end 13, and make down caulking groove 24 inwall elastic dilatations, be beneficial to bending end 13 slippages by described

grab

27,28.

Form by above-mentioned member, can be for implementing the utility model according to this, division uses step as follows now:

grab

27,28 orientation angle fittings 1 in following caulking groove 24.

2. the winding arm 11 of this corner connector 1 both-end is inserted in described frame 4, distolateral slot 42 and the passage 41 interior (as Figure 10, Figure 14, Figure 15 and shown in Figure 16) of 4a respectively, and disappear in

bar frame

4,4a, and by this ratchet part 111 hold and orientation angle fitting 1 distolateral in described

frame

4,4a, improve the steadiness of corner connector 1 and

bar frame

4,4a winding; Simultaneously, first side 251 of the otic placode 25 of this sheath 2 and second side 252 also can be respectively by winding arm 11 embedding groups in the distolateral slot 42 of described

frame

4,4a, and disappear in

bar frame

4,4a, reaching better engaging purpose, and the upper embedded groove 23 of sheath 2 is communicated with described frame 4, distolateral port 44 and the slot 43 of 4a respectively; So, this sheath 2 and is revealed in outside the framework 40 between two connected vertically

frames

4,4a, and the extrados 26 of sheath 2 is positioned at the corner of framework 40.

3. the upper embedded groove 23 interior (as Fig. 7 and shown in Figure 9) of this sheath 2 is implanted at the end angle 31 of these solar panels 3; Simultaneously, because this upper embedded groove 23 is communicated with the slot 43 of described

frame

4,4a respectively, so these solar panels 3 end limits can be implanted the slot 43 interior (as shown in Figure 8) of described

frame

4,4a respectively.

4. repeat implementation step 1 to step 3, and then form this framework 40 (as Fig. 5 and shown in Figure 6) in these solar panels 3 peripheral windings.

In view of the above, the utility model embodiment has following advantage in fact:

1. when a described

frame

4,4a and corner connection device 10 make up, do not have the abutting end of

bar frame

4,4a or the situation that screw exposes, therefore possess overall appearance.
