[Background technology]

[0002] 2. Description of the Related Art Generally, electronic devices used in various industrial fields, including automobiles, are provided with a printed circuit board on which various components can be mounted.

[0003] Such a printed circuit board has a number of connection terminals for electrically connecting various components, and connectors for connecting to mating connectors of corresponding boards are installed on the connection terminals of the printed circuit board.

[0004] A conventional connector includes a housing that is coupled to the surface of a board, and terminals that are coupled to the housing and coupled to connect with connection terminals of the board. The terminals are divided into power terminals for supplying power and signal terminals for transmitting signals.

[0005] However, in conventional connectors, the allowable current of the power terminals is fixed, so if an overcurrent is applied, the electronic device may break down, and so a structure that can withstand the application of an overcurrent is required.In addition, in conventional connectors, the power terminals and signal terminals are aligned using a transport carrier during assembly, and then insert molding is performed, and the process of separating the carrier from the power terminals and signal terminals is cumbersome.

[0006] A prior document related to the present invention is Korean Patent Registration No. 10-1185545 (September 18, 2012), which discloses a connector for connecting boards. [Prior art documents] [Patent documents]

[0068] Here, the extended end of the mounting portion 232 is exposed to the side of the housing 100 to connect to the third transfer carrier 30, and when separated from the third transfer carrier 30, a vertically cut cross-sectional portion 232a is formed.

[0072] Here, the outer contact portion 234 may have a contact portion 235 protruding therefrom so as to be connected to a mating connector (not shown) when the mating connector is coupled.

[0073] Each sub-power terminal 220 is connected to a power source and is installed in the second insertion portion 112 of the insertion protrusion 110, and may be installed on both sides of the second insertion portion 112 in the length direction.

[0074] Here, the sub-power terminals 220 are respectively installed between the main power terminals 210 and the signal terminals 230 installed in the second insertion portion 112, and the sub-power terminals 220 may be installed one by one between each main power terminal 210 and each signal terminal 230.

[0076] 1, 4 and 5, the sub-power terminal 220 has a width greater than that of the signal terminal 230 along the length direction of the second insertion portion 112. As shown in FIG.

[0077] Also, as shown in FIG. 6, each main power terminal 210 may be divided into a first terminal 210A arranged in the first insertion portion 111 and a pair of second terminals 210B bent and extended from both sides of the first terminal 210A and respectively arranged in the second insertion portion 112.
