Description

Technical Field

[0001] This utility model belongs to the field of PCBA processing technology, and in particular relates to a fisheye pin press-fit structure in PCBA. Background Technology

[0002] Fisheye pin press-fitting in PCBA is a connection process in which flexible or solid pins are pressed into the metallized holes of the PCB to form mechanical and electrical connections. This technology has been widely used in PCBAs in various fields.

[0003] In existing press-fit structures, if the press plate is not properly positioned, the PCBA may not be able to couple perfectly with the fisheye pins, resulting in damage to the circuit board during press-fitting. Excessive pressing force can also damage the PCBA, increasing the risk of defective products. Therefore, this invention proposes a fisheye pin press-fitting structure for PCBA to solve the above problems. Utility Model Content

[0004] This invention provides a fisheye pin press-fit structure for PCBA, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a fisheye pin press-fit structure in PCBA, including a press-fit plate and a PCBA board;

[0006] The top surface of the pressing plate is provided with three positioning plates arranged in a U-shape. The three positioning plates are used to position the three sides of the PCBA board. Positioning holes are also provided above the positioning plates. Three pressing pads are provided between the three positioning plates. One pressing pad is close to the positioning plate located on the left, one pressing pad is close to the positioning plate located on the right, and one pressing pad is close to the positioning plate located below. The pressing pads have elastic force.

[0007] The PCBA board is located on top of the press-fit plate.

[0008] Preferably, the press plate further includes four bolt fixing holes arranged in a matrix, and the press plate is connected to the press-fitting equipment by bolts passing through the bolt fixing holes.

[0009] Preferably, the PCBA board has multiple mounting holes, and the mounting holes are coaxial with the positioning holes when the fisheye pins are press-fitted into the PCBA board.

[0010] Preferably, the pressure pad is the pressure point of the PCBA board.

[0011] Preferably, the press-fit pad is a rubber pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The press-fitting structure of this utility model has three U-shaped positioning plates, positioning holes and press-fitting pads, which can not only provide positioning for the press-fitting of the PCBA board, but also provide support and restoring force for the press-fitting of the PCBA board. This avoids inaccurate positioning, which may cause the PCBA board to fail to perfectly couple with the fisheye pins, thus damaging the circuit board during the press-fitting process. It can also avoid excessive press-fitting force, which may damage the PCBA board. Attached Figure Description
