Test bracket for circuit board

1. A test bracket for testing a circuit board, the test bracket comprising:

a base comprising a board and two posts perpendicularly extending up from the board and spaced apart from each other;

two connection pieces; and

a supporting member for supporting the circuit board, the supporting member comprising two poles and a plurality of ribs slidably connected between the two poles;

wherein first ends of the connection pieces are respectively detachably connected to the posts, and second ends of the connection pieces are respectively pivotably connected to outer sides of the two poles; and

wherein each pole defines a first slot in an outer surface of the pole, each post defines a plurality of through holes from top to bottom of the pole, and two screws respectively pivotably extend through two corresponding through holes of the posts and engage in the first slots of the poles.

2. The test bracket of claim 1 , wherein the board is rectangular-shaped, a holding portion extends up from a corner of the board, the holding portion comprises a rod and an arm extending from a top of the rod, the arm is made of pliable metal material.

3. The test bracket of claim 1 , wherein a through hole is defined in the first end of each connection piece, a screw extends through the through hole of the connection piece and a corresponding through hole of the corresponding post, and engages with a nut.

4. The test bracket of claim 3 , wherein a pin extends from the second end of each connection piece, and pivotably engages in the first slot of the corresponding pole.

5. The test bracket of claim 1 , wherein the supporting member is made of insulating material.

6. The test bracket of claim 1 , wherein each pole defines two second slots in an inner surface of the pole, a plurality of spaced threaded holes is defined in each rib, opposite ends of the ribs are slidably engaged in the corresponding second slots of the poles.

7. The test bracket of claim 1 , wherein each rib is attached with a plurality of blocks each defining a threaded hole.

8. The test bracket of claim 1 , wherein the supporting member further comprises two bars, each bar defines a third slot in a side of the bar to receive a corresponding side of the circuit board, and one of the bars is movably connected between the poles.

9. A test bracket for testing a circuit board, the test bracket comprising:

a base comprising a board and two posts perpendicularly extending up from the board;

two connection pieces; and

a supporting member for supporting the circuit board, the supporting member comprising two poles, and two bars connected between the poles to hold the circuit board among the poles and the bars;

wherein first ends of the connection pieces are respectively detachably connected to the posts, and second ends of the connection pieces are respectively movably connected to the poles, at least one of the bars is slidably connected between the poles; and

wherein each pole defines a first slot in an outer surface of the pole, each post defines a plurality of through holes from top to bottom of the pole, and two screws respectively pivotably extend through two corresponding through holes of the posts and engage in the first slots of the poles.

10. The test bracket of claim 9 , wherein a through hole is defined in the first end of each connection piece, a screw extends through the through hole of the connection piece and a corresponding through hole of the corresponding post, and engages with a nut.

11. The test bracket of claim 10 , wherein a pin extends from the second end of each connection piece, and pivotably engages in the first slot of the corresponding pole.

12. The test bracket of claim 9 , wherein the supporting member is made of insulating material.
