Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, a local tin plating tool for an inter-board connector pin comprises a tin plating tool main body 1, an inter-board connector placing area 2, an inter-board connector picking position 3, a device fixing clamp spring 4, a tin plating opening 5, a device pin partition plate sliding groove 6, a device pin partition plate 7 and an inter-board connector 8. The connector placing area 2 between the boards is arranged on the upper surface of the tin-lined tool main body 1, and the device fixing clamp springs 4 are respectively located on two sides of the upper end of the connector placing area 2 between the boards.
The tin-coating tool main body 1 is integrally square plate-shaped and is realized by adopting a synthetic stone material. The device fixing clamp spring 4 is realized by a universal fixing clamp spring.
The board-to-board connector placing area 2 is a special-shaped groove which is equivalent to the shape of the connector. The board-to-board connector placement area 2 is used for accommodating a board-to- board connector 8, and 8 circular grooves are specially designed at corners of the board-to-board connector end face for preventing the corners from being worn when the connector is placed horizontally.
