Referring to FIG. 8 , the second connector 3a of this embodiment is inserted into the adapter socket 10T along a direction perpendicular to the top surface 101 of the first connector 1a. When the second connector 3 a is inserted into the adapter socket 10T, the second contact portion 42 of the second electrical terminal 40 contacts the middle portion 23 of the first electrical terminal 20 . Meanwhile, the second insulating housing 30 is limited between the pair of limiting side walls 12 . Thereby, the present embodiment enables the current of the first connector 1a to pass through the middle portion 23 of the first electrical terminal 20 It is transmitted to the second electrical terminal 40 of the second connector 3a, and is transmitted through the cable C to other components requiring current.

Please refer to FIG. 1 at the same time, wherein the exposed area 14 is located in the adapter socket 10T, and at least one exposed hole 140 is formed. The exposed hole 140 is recessed downward from the exposed area 14 and communicated with the slot 11 . The exposed hole 140 exposes the middle portion 23 of the first electrical terminal 20 . The first electrical terminal 20 exposed in the exposed hole 140 includes a power terminal that provides a power supply potential (for example, the first electrical terminal 20 of the first shunt slot on the left side of FIG. 1 ), and a ground potential that provides a ground potential. A power terminal (for example, it may be the first electrical terminal 20 of the second shunt slot on the right side of FIG. 1 ).

In another application, the first shunt slot (or shunt hole) exposes a plurality of first electrical terminals 20 , including at least one power terminal for providing a power supply potential and at least one power terminal for providing a ground potential. The second connector 3a disposed in the first shunt slot also includes a second power supply terminal corresponding to the power supply potential and a second power supply terminal corresponding to the ground potential, which are electrically isolated and disconnected from each other (see FIG. 4 ). The cable C also provides power supply potential and ground potential to electronic components (eg, connectors) corresponding to the second pins of the power supply terminal connected to the power supply potential and the second pin of the power supply terminal of the ground potential, respectively. In this way, a single second connector 3a can directly provide a current loop to the electronic components connected to the second connector 3a.

The cables C connected to the second connector 3a may run in the same direction or in different directions (eg, opposite directions). Referring to FIG. 4 again, a plurality of cables C connected to the same second connector 3a have the same direction. Specifically, the same second connector 3 a has two (or more) second electrical terminals 40 , and the second pins 43 of the second electrical terminals 40 are connected by one side of the second insulating housing 30 (hereinafter referred to as “connection”). The foot side) extends outward to different positions (that is, the distance from the end of the second pin 43 to the pin side of the second insulating shell 30 is different), so that the two (or more) second pins 43 have different distances. When the connected cables C go in the same direction, their positions are staggered. That is to say, the cable connection surfaces of the two (or more) second electrical terminals 40 are staggered with each other, so that the cables C of the same direction connected to these cable connection surfaces can be staggered. in Figure 4 In the illustrated embodiment, the second pin 43 has a bending portion, so that the second pin 43 is bent upward. Please refer to FIG. 7 at the same time, the positions of the bending parts are different from front to back, so that the corresponding cables C run in the same direction, but the positions are different from front to back. Therefore, if the same second connector 3a has the cables C for supplying the power supply potential and the ground potential at the same time, and the cables C have the same orientation, it can be easily connected to the same electronic component.
