[0022] Reference Figures 1 to 4 The utility model provides a composite material frame assembly connector: including a bottom plate 1, each side of the bottom plate 1 is vertically penetrated by a first notch 2 and a second notch 3, and a notch 6 communicating with the second notch 3 is respectively provided at both ends of the bottom plate 1, a positioning block 9 is fixedly connected to the inner side of the bottom plate 1, and the top surface of the positioning block 9 is provided with a third inclined surface 8 inclined toward the end of the bottom plate 1, and the inner side of the bottom plate 1 is provided with a stepped surface 10 lower than its end surface, the positioning block 9 is fixed on the stepped surface 10, and the elasticity of the stepped surface 10 at the bottom plate 1 is greater than the elasticity of the bottom plate 1 as a whole, and the step difference between the stepped surface 10 and the inner side of the bottom plate 1 is 1-2mm, the bottom of the bottom plate 1 is rigid, and forms a right angle, the positioning block 9 and the third inclined surface 8 on the positioning block 9 constitute a convex buckle structure, which is used in the pre-opening hole of the future frame;

[0023] By setting the bottom plate 1, a notch 6 is passed through the second notch 3 on the bottom plate 1, a positioning block 9 is fixed on the bottom plate 1, and the elasticity of the positioning block 9 installation position is increased, so that the photovoltaic frame and the assembly connector can be easily installed without the need for fixing with bolts, rivets and other parts, thereby reducing the difficulty of installing the photovoltaic frame;

[0024] Reference Figure 1 and Figure 2 In order to reduce the weight of the assembly connector and improve the support strength of the assembly connector, the bottom plate 1 is made of plastic material as a whole, and the first support block 12 and the second support block 11 are respectively fixed in the first notch 2 and the second notch 3, and the first support block 12 and the second support block 11 are both made of metal;

[0025] Reference Figures 1 to 4In order to improve the convenience of installing the assembly connector and the profile, a first inclined surface 5 approaching the middle is provided on both sides of each end of the bottom plate 1, and a guide groove 4 is provided on both sides of the bottom plate 1. The drop between the guide groove 4 and the side of the bottom plate 1 is 1-2 mm. The inner end of the bottom plate 1 is provided with a second inclined surface 7 bent toward the notch 6, and the second inclined surface 7 is rounded. By arranging the first inclined surface 5 and the guide groove 4 on the bottom plate 1, and arranging the second inclined surface 7 at the notch 6 end of the bottom plate 1, it is convenient to insert the bottom plate 1 into the photovoltaic frame profile, reducing the obstruction of the assembly connector in the inserted profile, saving the effort spent on installing the profile and the assembly connector, and the second inclined surface 7, the third inclined surface 8, the positioning block 9 and the stepped surface are all elastic structures, so that the convex buckle structure can be smoothly inserted into the square hole of the frame.

[0026] Working principle: When in use, a profile with a positioning groove on the inner wall is inserted at each end of the base plate 1. When the L-shaped block is inserted into the profile, under the action of the elastic step surface 10 of the base plate 1 and the first inclined groove and the second inclined groove, the end face of the positioning block 9 that slides into the profile abuts against the inner wall of the profile, so that the step surface 10 of the base plate 1 will be in a bent state until the positioning block 9 moves to a position concentric with the positioning groove in the profile. The bent step surface 10 on the base plate 1 is reset under the action of elasticity. When resetting, the positioning block 9 is pushed into the positioning groove of the profile, thereby completing the installation of the assembly connector and the photovoltaic frame profile.
