Detailed Description
An improved structure of a vertical connector middle needle comprises a plastic needle seat 1, a positioning sheet 2 and a middle needle 3, a plurality of middle needle guide grooves 1-1 are formed in the plastic pin base 1 along the vertical direction, the middle needle 3 is of an L-shaped structure, the middle needle 3 comprises a vertical inserting portion 3-1 and a horizontal contact portion 3-2, the inserting portion 3-1 comprises two vertical contact pins, a U-shaped opening clamping groove 3-3 for clamping an external terminal is formed between the two vertical contact pins, the inserting portion 3-1 is inserted into the middle needle guide grooves 1-1, positioning piece inserting grooves 1-2 are formed in positions, close to the two sides, of the plastic pin base 1, the cross section of each positioning piece 2 is of an L shape, the vertical positioning portion 2-1 of each positioning piece 2 is inserted into the corresponding positioning piece inserting groove 1-2, and the horizontal positioning portion 2-2 of each positioning piece 2 is fixedly connected with an external PCB in a welding mode.
The plastic needle seat 1 adopts a vertical structural design, and a plurality of middle needle guide grooves 1-1 are formed in the plastic needle seat 1 along the vertical direction, so that the plastic needle seat is suitable for being vertically installed and used with a PCB. Will the utility model discloses when erection joint is on the PCB board, horizontal location portion 2-2 welded connection of spacer 2 is on the PCB board, and the contact site 3-2 and the PCB board contact of well needle 3, the utility model discloses keep away from the one end and the terminal plug-in connection of PCB board, terminal centre gripping realizes the intercommunication of circuit to in U-shaped opening centre gripping groove 3-3.
The plastic needle seat 1 is integrally provided with two positioning guide blocks 1-3, the two positioning guide blocks 1-3 are symmetrically arranged, and the middle needle guide groove 1-1 is positioned between the two positioning guide blocks 1-3. The two positioning guide blocks 1-3 play a role in guiding when being connected with the terminal in an inserting way and also play a role in protecting the middle needle 3.
The edge of the horizontal positioning part 2-2 of the positioning plate 2 is provided with a welding tin-absorption notch 2-3. When in welding, more solder paste can be fixed on the positioning sheet 2, and the fixation is firm.
