Description

  The present invention relates to an electrical connector, and more particularly to an electrical connector that is fixed to a circuit board and electrically connected to the circuit board.

  An electrical connector in the electronic industry is fixed to a circuit board to form a path for realizing signal transmission, usually by USB (Universal Serial Bus). The circuit board is provided with a plurality of through holes. In the conventional electrical connector, the fixing portion provided in the housing surrounding the insulating body is inserted into the corresponding through hole by THT (Through Hole Technology). By being soldered to the circuit board, it is fixed to the circuit board. Patent Document 1 also discloses an electrical connector that is soldered to this type of circuit board. However, the fixing portion needs to be very hard so that the electrical connector can be soldered to the circuit board by THT. Otherwise, the fixing portion may be deformed after being attached or detached, or may be detached from the circuit board, and it is difficult to maintain good signal transmission.

Therefore, it is necessary to design a new electrical connector to overcome the above disadvantages.
