This patent application discloses a small electrical connector with a small height, which includes an insulating body, a terminal module housed in the insulating body, a sub-circuit board and A transformer module, the terminal module and the transformer module are arranged on the sub-circuit board, the sub-circuit board is perpendicular to the insertion direction of the docking connector, and the terminal module and the transformer module are arranged side by side on the same side of the sub-circuit board. side. Although the existing arrangement of electrical connectors reduces the height of the electrical connector, the terminal module and the transformer module are arranged on the same side of the sub-circuit board, so that the accommodation space of the transformer module is small, and the butt terminals And the welding of the transformer module and the sub-circuit board is inconvenient.

【Content of utility model】

The technical problem to be solved by the utility model is to provide a low-structural electrical connector that can increase the space for placing the transformer coil and is convenient for welding.

The technical problem to be solved by the utility model is achieved through the following technical solutions: an electrical connector, which can be installed on a circuit board, and is used to connect the butt connector inserted into the electrical connector perpendicular to the direction of the circuit board to the The circuit board described above, the electrical connector includes an insulating body, a built-in circuit board accommodated in the insulating body, a number of docking terminals for connecting the butt connector to the built-in circuit board, transfer terminals for connecting the built-in circuit board to the aforementioned circuit board, and A plurality of transformer coils arranged on a built-in circuit board, the built-in circuit board is parallel to the insertion direction of the butt connector, the plurality of butt terminals and transfer terminals are arranged on one side of the built-in circuit board, and the plurality of transformer coils are arranged on the other side of the built-in circuit board.

Compared with the prior art, the electric connector of the utility model separates the docking terminal, the transfer terminal and several transformer coils on both sides of the built-in circuit board, which not only satisfies the smaller height of the electrical connector, but also increases the size of the transformer coil. The placement space is convenient for coil welding.
