As shown in a), the coupling portion 331 for fixedly coupling to the housing 310, the hook portion 334 to be fitted into the engaging hole 321 of the actuator to prevent separation of the actuator 320, the FPCB An FPCB contact portion 333 in contact with the contact and a hard PCB contact portion 335 in contact with the plug 24 on the rigid PCB side are inserted into the first type terminal groove 313.

In addition, the even-numbered second type metal terminal 340 has a coupling portion 341 for fixed coupling with the housing 310 and an FPCB contact portion in contact with the contact point of the FPCB, as shown in FIG. 343, the PCB contact portion 345 which contacts the plug 24 on the rigid PCB side is inserted into the second type terminal groove 314.

Comparing the first type metal terminal 330 and the second type metal terminal 340, the ring type 134 for hanging the actuator 320 is formed in the first type metal terminal 330. It can be seen that the two types of metal terminals 340 have no loop portion, and the length of the FPCB contact portion 333 of the first type is shorter than that of the FPCB contact portion 343 of the second type, thereby forming two contact points as a whole. . In addition, the position of the rigid PCB contact portion 335 of the first type and the position and the orientation of the rigid PCB contact portion 345 of the second type are different, so that the portion contacting the PCB 50 may form two contact points as a whole.

As shown in FIG. 16, the connector 300 according to the third exemplary embodiment of the present invention inserts the FPCB 30 into the guide 312 while the actuator 320 is opened, and then the actuator 320. To close the FPCB 30 and insert the plug 24 soldered to the rigid PCB 50 into the receiving groove 315 of the housing to connect the plug 24 soldered to the FPCB 30 and the rigid PCB 50. Allow to fasten directly.

As shown in FIG. 17, the FPCB 30 and the rigid PCB 40 are connected to the first type metal terminal 330 by the connector 300 according to the third embodiment of the present invention. . Referring to FIG. 17, the first type metal terminal 330 is inserted into the first type terminal groove 313 of the housing to be fixedly coupled to the housing 310 by the coupling part 331, and the FPCB 30 is The F320B contact part 333 and the FPCB 30 contact of the first type metal terminal 330 are fixed to the housing 310 by the actuator 320 to form an electrically conductive path. The plug 24 mounted on the rigid PCB 50 is inserted into the receiving groove 315 of the housing so that the metal terminal of the plug 24 comes into close contact with the rigid PCB contact portion 335 of the first type metal terminal, thereby providing an electrically conductive path. Therefore, the FPCB 30 is directly connected to the plug 24 soldered to the rigid PCB 50 through the first type metal terminal 330 made of one metal piece.

A form in which the FPCB 30 and the PCB 50 are connected to the second type metal terminal 340 by the connector 300 according to the third embodiment of the present invention is illustrated in FIG. 18. Referring to FIG. 18, the second type metal terminal 340 is inserted into the second type terminal groove 314 of the housing and fixedly coupled to the housing 310 by the coupling part 341. In addition, the FPCB 30 is fixed to the housing 310 by the actuator 320, and the FPCB contact portion 343 of the second type metal terminal 340 and the contacts of the FPCB 30 closely contact each other to form an electrically conductive path. Forming. The plug 24 soldered to the PCB 50 is inserted into the receiving groove 315 of the housing 110 so that the metal terminal of the plug 24 is in close contact with the rigid PCB contact portion 345 of the second type metal terminal. Forming a conductive path, the FPCB 30 is thus electrically connected directly to the plug 24 soldered to the rigid PCB 50 via the second type metal terminal 340 of one metal piece.
