Description

Technical Field

[0001] The utility model relates to a circuit board detection technology, in particular to a circuit board detection device. Background Art

[0002] After the circuit board is manufactured, it needs to be inspected. During the assembly process, defects such as cold solder joints and leaking solder joints may occur on the circuit board, which may cause the circuit board to fail to conduct normally.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figures 1 to 4 As shown, the circuit board detection device of the utility model comprises a fixing seat 1, which is composed of a bottom plate 2, a blocking portion 3 arranged on one side of the bottom plate 2, and a fixing portion 4 arranged on the other side. The circuit board 5 can be first inserted into one end of the fixing portion 4, and then the end close to the blocking portion 3 is pressed down, so that the circuit board 5 can be fixed quickly and stably.

[0019] A support portion 6 is provided on the blocking portion 3, and the support portion 6 is used to support one end of the circuit board 5. A symmetrically arranged deformable arm 7 and a clamping arm 8 are provided on the fixing portion 4. When the deformable arm 7 is used for clamping by the clamping arm 8, the deformable arm 7 can be deformed and bent by force. When not clamping, the elastic force of the deformable arm 7 keeps the clamping arm 8 restored to its original shape.

[0020] The deformable arm 7 is connected to the fixed portion 4 through the mounting portion 9. An elastic portion 10 is provided between the clamping arms 8. The elastic portion 10 is arc-shaped. When the clamping arms 8 are opened, the elastic portion 10 protrudes toward the mounting portion 9. When the clamping arms 8 are closed, the elastic portion 10 protrudes toward the fixed portion 4.

[0021] The clamping arm 8 is arranged in an arc shape, so that one end of the clamping arm 8 can clamp the circuit board 5 in a line contact manner, thereby ensuring that the circuit board 5 is not damaged during clamping.

[0022] A clamping area 11 is formed between the clamping arms 8 , and the clamping area 11 is used to clamp one end of the circuit board 5 .

[0023] A deformation region 12 is formed between the symmetrically arranged deformation arms 7 , the elastic portion 10 and the mounting portion 9 , and the deformation region 12 is used for the elastic portion 10 to contract.

[0024] Embodiment 1

[0025] By arranging a positioning post 13 in the deformation area 12, a spring 14 is sleeved on the positioning post 13, one end of the spring 14 contacts the mounting portion 9, and the other end contacts the elastic portion 10. The spring 14 pushes the elastic portion 10, so that the elastic portion 10 needs to be pushed by a larger external force, and the same external force is maintained to push the elastic portion 10, so that the circuit board 5 can be better pushed by the external force, thereby fixing the circuit board 5.

[0026] Embodiment 2

[0027] An arc-shaped elastic sheet (not shown in the figure) is provided in the middle of the elastic part 10 , and the elastic sheet can increase the elastic force of the elastic part 10 to clamp and fix the circuit board 5 .

[0028] During installation, first insert one end of the circuit board 5 into the clamping area 11, then push the elastic part 10 with force so that the elastic part 10 is forced to shrink into the deformation area 12, and then press the other end of the circuit board 5 onto the supporting part 6. At this time, the circuit board 5 will be subjected to the reverse force from the elastic part 10, and the circuit board 5 will be fixed, thereby facilitating the inspection of the circuit board 5.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
