The signal source 3 is, for example, a power supply. As shown in Figures 11 to 12, the conductive terminal 11 has a circuit board contact section 111, a signal source connecting section 112, a connecting section 113 and an abutting section 114, and the conductive terminal 11 can be in the first form or the second form under force. . It should also be noted that the clamping terminal 12 is used to clamp the circuit board 2. In the present invention, the clamping terminal 12 is an unnecessary component, and the connecting section 113 is used to connect the contacting sections of the circuit board on both sides. 111 is connected to section 112 with the signal source.

As shown in FIG. 11, when the conductive terminal 11 is in the first state under force, the circuit board contact section 111 is in electrical contact with the circuit board 2, and the signal source connection section 112 is electrically connected to the signal source 3. At this time, the signal The source connection section 112 , the connection section 113 and the circuit board contact section 111 constitute an electrical communication line, so as to achieve electrical communication between the signal source 3 and the circuit board 2 .

As shown in FIG. 12, the abutment section 114 has a first abutment structure 1141. When the conductive terminal 11 is in the second form, the circuit board contact section 111 is in electrical contact with the circuit board 2, and the signal source connection section 112 is electrically connected. The signal source 3, and the first abutment structure 1141 of the abutment section 114 is electrically abutted against the signal source connection section 112. At this time, the signal source connection section 112, the abutment section 114 and the circuit board contact section 111 form an electrical contact section 111. The circuit is connected to achieve electrical communication between the signal source 3 and the circuit board 2 .

In addition, it should be noted that the first abutting structure 1141 can not only electrically abut the signal source connection section 112, but also provide structural support for the circuit board contact section 111, so as to reduce the degree of deformation of the circuit board contact section 111 under force. , so as to prevent the circuit board contact section 111 from being flexibly deformed under force, thereby increasing the service life of the cable end connector 1 of the present invention.
