Abstract
The utility model discloses a horizontal needle seat including a needle seat body and a square needle. A square needle hole is disposed at the bottom of the needle seat body. The square needle is connected to the needle seat body through the square needle hole. The head end of the square needle is disposed in the needle seat body, and the tail end of the square needle is inserted in an installation hole of a PCB board. After passing through the square needle hole, the square needle is folded along the bottom of the needle seat body to form the tail end of the square needle. The tail end and the head end of the square needle are at a 90-degree angle to set the square needle in the shape of "L". The tail end of the square needle is provided with a bent portion comprising a first bent portion formed by a first bending of the tail end of the square needle and a second bent portion formed by a second bending of the tail end of the square needle. The first bending and the second bending are in opposite directions. The length of the second bent portion is greater than that of the first bent portion. The horizontal distance between the end of the first bent portion and the tail end of the square needle is 0.05 mm larger than the diameter of the installation hole. According to the utility model, the structural design of the square needle is changed for the horizontal needle seat, and thus the board clamping force between the horizontal needle seat and the PCB board is enhanced and swinging and falling off of the horizontal needle seat during welding are effectively prevented.
