In the present embodiment, the signal pin 4 includes a plurality of signal pins, and referring to fig. 4, the plurality of signal pins 4 may include a first signal pin 41 and a second signal pin 42. The first signal pin 41 and the second signal pin 42 are disposed at an interval, and the length of the first signal pin 41 is smaller than the lengths of the positive pin 2, the negative pin 3, and the other signal pins 4 (including the second signal pin 42) except the first signal pin 41. The corresponding position of the external equipment to be charged or powered is provided with an electric socket hole corresponding to the positive pin 2, the negative pin 3 and the signal pin 4, and when the external equipment is used in particular, the positive pin 2, the negative pin 3 and the signal pin 4 need to be in socket connection with the corresponding electric socket holes in the external equipment. In this embodiment, when the first signal pin 41 detects that the external device is plugged in the first signal pin 41, the trigger control circuit 5 controls the adapter 40 to output power to supply power to or charge the external device. In the embodiment of the present invention, the length of each pin (including the positive pin 2, the negative pin 3, and the signal pin 4) refers to the length of each pin exposed to the outside of the housing 1.
According to the adapter 40 of the embodiment of the present invention, since the length of the first signal pin 41 is set to be shorter than the lengths of other pins (including the positive pin 2, the negative pin 3, and the other signal pins 4 except the first signal pin 41), it can be ensured that when the external device is connected to the first signal pin 41 in an inserting manner, the external device is connected to the other pins in place, so that it is ensured that the contact area between the external device and the adapter 40 is large enough, and the risk of burning the adapter 40 due to the contact area being too small is reduced; and, whether external equipment and adapter 40 are pegged graft in place is judged through first signal contact pin 41 detection external equipment and this first signal contact pin 41 plug connection, only when first signal contact pin 41 detects external equipment and this first signal contact pin 41 plug connection, just can trigger control circuit 5 and control adapter 40 output power, realized charging or power supply to external equipment when having ensured that adapter 40 and external equipment are connected in place, the security that has improved to charge or supply power.

In this embodiment, the adapter 40 may be a part of the charger, or may be separately provided from the charger.
In another embodiment, the external device is a to-be-powered structure (such as a motor, a flight controller, etc.) of an unmanned aerial vehicle (such as an agricultural plant protection machine), the adapter 40 of the embodiment is an external electrical connector of a battery, and before the to-be-powered structure is powered, the to-be-powered structure is plugged in the adapter 40, so that the to-be-powered structure is powered through the battery, and the to-be-powered structure is powered on and operates.
The lengths of the positive pin 2, the negative pin 3 and the other signal pins 4 except the first signal pin 41 can be designed as required, for example, in an embodiment, the lengths of the positive pin 2, the negative pin 3 and the other signal pins 4 except the first signal pin 41 are equal. In another embodiment, the length of the positive pin 2 is equal to the length of the negative pin 3, and the lengths of the other signal pins 4 except the first signal pin 41 are slightly smaller than the lengths of the positive pin 2 and the negative pin 3, so that the signal pin 4 can be distinguished from the positive pin 2 and the negative pin 3.
In the plurality of signal pins 4 of the present embodiment, each signal pin 4 corresponds to a function, for example, the first signal pin 41 is used to detect whether the external device and the adapter 40 are inserted in place, and the second signal pin 42 is used to transmit data information between the external device and the adapter 40.
The number of the signal pins 4 can be designed according to the functional requirements, and referring to fig. 4, in this embodiment, the plurality of signal pins 4 further includes a third signal pin 43 and a fourth signal pin 44. Of course, the number of the signal pins 4 is not limited to 4, and the number of the signal pins 4 can be increased or decreased according to the functional requirements, and the number of the signal pins 4 is not limited in this embodiment.
The structure of the contact 40 will be further described by taking the example in which the signal pin 4 includes a first signal pin 41, a second signal pin 42, a third signal pin 43 and a fourth signal pin 44.
In this embodiment, the thickness of the signal pins 4 is relatively thin, so as to reinforce the signal pins 4 and prevent abrasion caused by plugging.

For example, in one embodiment, the positive pin 2, the negative pin 3 and the signal pin 4 are all sheet-like structures, which increases the contact area when each pin is connected with an external device. Optionally, the surfaces of the positive pin 2, the negative pin 3 and the signal pin 4 are parallel to each other, so that external equipment can be conveniently plugged, and the arrangement mode is more attractive. Of course, the surfaces of the positive pin 2, the negative pin 3 and the signal pin 4 may also have a certain inclination angle, and the position relationship among the surfaces of the positive pin 2, the negative pin 3 and the signal pin 4 may be specifically set as required.
In another embodiment, the positive pin 2, the negative pin 3, and the signal pin 4 are all cylindrical or other regular shapes, and the shapes of the positive pin 2, the negative pin 3, and the signal pin 4 can be designed according to the requirement.

The following description will be made by taking as an example a structure in which the first signal pin 41, the second signal pin 42 and the corresponding insulator 6 are integrally formed, the third signal pin 43, the fourth signal pin 44 and the corresponding insulator 6 are integrally formed, and the positive pin 2 and the negative pin 3 are all in a sheet shape. In this embodiment, the entire first signal pin 41, the entire second signal pin 42 and the corresponding insulator 6, the entire third signal pin 43, the entire fourth signal pin 44 and the corresponding insulator 6 are equal to the lengths of the positive pin 2 and the negative pin 3, and the entire first signal pin 41, the entire second signal pin 42 and the corresponding insulator 6, and the entire third signal pin 43, the entire fourth signal pin 44 and the corresponding insulator 6 are equal to the thicknesses of the positive pin 2 and the negative pin 3.
Of course, in other examples, the whole of the first signal pin 41, the second signal pin 42 and the corresponding insulator 6, and the whole of the third signal pin 43, the fourth signal pin 44 and the corresponding insulator 6 are equal to the lengths of the positive pin 2 and the negative pin 3, while the whole of the first signal pin 41, the second signal pin 42 and the corresponding insulator 6, and the whole of the third signal pin 43, the fourth signal pin 44 and the corresponding insulator 6, and the thicknesses of the positive pin 2 and the negative pin 3 may be designed to be partially equal or unequal.

In the correlation technique, positive contact pin 2 and negative pole contact pin 3 adjacent setting of adapter 40, the phenomenon of striking sparks takes place easily to positive contact pin 2 and 3 distances of negative pole contact pin are too close, causes the potential safety hazard. In contrast, in the present embodiment, the positive pin 2 and the negative pin 3 are respectively provided on both sides of the plurality of signal pins 4. Specifically, a plurality of signal contact pins 4 are one row of interval and locate between anodal contact pin 2 and the negative pole contact pin 3, with the design placed in the middle of a plurality of signal contact pins 4, have increased the distance between anodal contact pin 2 and the negative pole contact pin 3, have effectively avoided the risk that positive negative pole struck sparks.
In addition, in the related art, the adapter 40 can be easily used when one of the positive pin 2 and the negative pin 3 is in a problem due to insufficient redundancy of the positive pin 2 and the negative pin 3. In view of this, in the present embodiment, referring to fig. 3, the positive pin 2 includes a plurality of pins, and the negative pin 3 corresponds to the positive pin 2 and also includes a plurality of pins, that is, the number of the negative pins 3 is the same as the number of the positive pins 2.
