Abstract

The present invention provides a mounting bracket for a junction box utilized for solar cell, a junction box with the mounting bracket, and the solar cell module. The mounting bracket for the junction box comprises a joint arm, an insert strip, and a hook. The insert strip comprises a first elastic strip connecting with the joint arm, a joint strip connecting with the first elastic strip and bending towards the joint arm, and a second elastic strip connecting with the joint arm. The insert strip is used for inserting into the frame. At least one of the first and the second elastic strips of the insert strip comprise a first elastic block.

Claims

1. A mounting bracket for a junction box utilized for solar cells comprising a solar cell panel and a frame arranged on the edge of the solar cell panel , wherein

the mounting bracket for the junction box comprises a joint arm, an insert strip, and a hook;

the insert strip comprises a first elastic strip connecting with the joint arm, a joint strip connecting with the first elastic strip and bending towards the joint arm, and a second elastic strip connecting with the joint strip;

the insert strip is used for inserting into the frame, which comprises an upper edge, a lower edge, and a lateral edge connecting the upper edge and the lower edge;

the upper edge and the lower edge are parallel with each other;

the lateral edge joints the joint strip, the lower edge joints the first elastic strip, and the upper edge joints the second elastic strip;

the hook connected to the joint arm by an extension arm is utilized for fixing to an outside of the lateral edge of the frame, in order to lock the mounting bracket for the junction box to the frame; and

at least one of the first and the second elastic strips of the insert strip comprises a first elastic block, and when the insert strip is inserted into the frame of the solar cell panel, the first elastic block is pressed fit on an inside of either the upper or lower edge of the panel frame, to strengthen a joint part of the mounting bracket and the frame.

2. The mounting bracket for the junction box of claim 1, wherein both the first elastic strip and the second elastic strip of the inset strip comprise the first elastic block.

3. The mounting bracket for the junction box of claim 1, wherein one of the first elastic strip and the second elastic strip of the inset strip comprises the first elastic block.

4. The mounting bracket for the junction box of claim 1, wherein the hook is an arc-shaped spring, and the terminal or the bottom of the arc-shaped hook is pressed fit to the outside of the lateral edge.

5. The mounting bracket for the junction box of claim 1, wherein a space is between a plane of the extension arm and a plane of the first elastic strip, and when the insert strip is inserted into the frame, the lower edge of the frame is inserted into the space.

6. The mounting bracket for the junction box of claim 5, wherein the mounting bracket further comprises a second elastic block, the second elastic block is set at opposite part of the first elastic block on the extension arm, and when the insert strip is inserted into the frame of the panel, and then the second elastic block is deformed for compressed by the lower edge of the frame, to strengthen the joint part of the mounting bracket and the frame.

7. The mounting bracket for the junction box of claim 1, wherein the mounting bracket further comprises an operation handle connected with the joint arm, utilized for pushing the insert strip of the mounting bracket for the junction box in the frame and pulling the mounting bracket for the junction box from the frame by operating the operation handle.

8. The mounting bracket for the junction box of claim 1, wherein the mounting bracket further comprises an unlocking handle set on a terminal of the hook away from the joint arm, utilized for making the hook released from the outside of the lateral edge of the frame.

9. The mounting bracket for the junction box of claim 1, wherein the number of the joint arms, the insert strips, and the hooks is two, and the two joint arms, the two insert strips, and the two hooks are set symmetrically.

10. The mounting bracket for the junction box of claim 1, wherein a plurality of holes which the screws can pass through are set in the joint arm and the screws pass through the holes and then joint the junction box and the mounting bracket.

11. The mounting bracket for the junction box of claim 1, wherein the joint arms, the insert strips, and the hooks are formed in one-piece.

12. A junction box, wherein the junction box comprises the mounting bracket described in claim 1, and the junction box is connected with the joint arm by a plurality of screws.

13. A solar cell module, wherein the solar cell module comprises a solar cell panel, a frame, and the mounting bracket of claim 1;

the frame is set around the solar cell panel; and

the insert strip of the mounting bracket is inserted into a capacity space defined by an upper edge, a lower edge, and a lateral edge connecting the upper edge and the lower edge of the frame.
