The plug contact part 144 of the plug module 140 is, for example, in the form of a female socket, which has a positioning post 144a, a clamping spring set 144b and a buckling part 144c. The cable interface 1142 is, for example, a protruding male plug. In this embodiment, it can be roughly divided into a positioning post contact portion 1142a, a cable contact portion 1142b, a stopper portion 1142c, and a guide hole 1142d.

When the plug contact portion 144 of the plug module 140 is to be connected with the cable interface 1142 of the main body 110 , the positioning post 144 a can be engaged with the positioning post contact portion 1142 a by being guided by the guide hole 1142 d. In detail, the positioning column 144a is a straight column, and its cross-sectional shape can be circular, square, rectangular, triangular, elliptical, or polygonal. The guide hole 1142d is also a straight channel with the same cross-sectional shape and slightly larger than the positioning post 144a, so that the positioning post 144a can be stably engaged with the positioning post contact portion 1142a straight and not skewed. In addition, the contact portion 1142a of the positioning post may be, for example, a clamping elastic piece, which stabilizes the positioning post 144a through frictional force. It should be noted that the contact portion 1142a of the positioning pin can also be any other movable connection method such as magnetic attraction, which is not limited in this application.

The cable contact portion 1142 b of the cable interface 1142 can be smoothly engaged with the clamping shrapnel group 144 b of the plug contact portion 144 through the straight engagement of the positioning post 144 a with the positioning post contact portion 1142 a. Wherein, the number of clamping elastic sheet sets 144b is the same as the number of pins of the cable contact portion 1142b, and the clamping elastic sheet sets 144b correspondingly clamp and fix the corresponding pins of the cable contact portion 1142b.

The plug module 140 can further stabilize the connection with the cable interface 1142 through the fastening portion 144c. Wherein, the buckling portion 144c of the plug module 140 is a protruding buckle, and the stopper portion 1142c of the cable interface 1142 is a protrusion for buckling designed corresponding to the buckling portion 144c, as shown in FIG. 5 .

The magnetic component 1202 is, for example, a permanent magnet made of ferrite, alnico, rare earth magnet, neodymium magnet and samarium cobalt magnet. When the first adapter base 120 is inserted into the slot 1122, the magnetic component 1202 can absorb the first adapter interface 122 through magnetic force, so as to strengthen the connection and fixation of the two, and prevent the first adapter base 120 from accidentally loosening.

For example, the magnetic sensing component 1222 can judge whether the first adapter base 120 is placed correctly by judging the contact area or the magnitude of the magnetic force between the magnetic component 1202 and the magnetic sensing component 1222 . When the magnetic sensing component determines that the first adapter base 120 is placed correctly, the first adapter interface 122 can transmit the DC signal to the first adapter base 120 to prevent the danger of electric leakage.

In addition, the magnetic sensing component 1222 can also be a component with a magnetic function, so as to be attracted to the magnetic component 1202 of the first adapter base 120 through the through hole 1122 a when the first adapter base 120 is installed in the slot 1122 . It should be understood that, in one embodiment, the magnetic sensing element 1222 can be purely ferromagnetic (ferromagnetic) metal for the magnetic attraction of the magnetic element 1202 . Alternatively, the magnetic sensing component 1222 is a permanent magnet and the magnetic component 1202 is a ferromagnetic (ferromagnetic) metal, so as to actively attract the magnetic component 1202 .

Continuing from the above embodiment, the terminals 1204 and 1206 of the first adapter base 120 are, for example, POGO PINs or terminals suitable for electrical connection with POGO PINs, so as to connect with the first adapter through the through hole 1122a when inserted into the slot 1122. The interfaces 122 are electrically connected. In detail, the terminal 1204 is used to transmit the first voltage level from the first conductive portion 1224 of the first transfer interface 122 , and the terminal 1206 is used to transmit the second voltage from the second conductive portion 1226 of the first transfer interface 122 quasi-position. It is worth mentioning that, for example, the first transfer interface 122 is configured as a concentric circle, that is, the first conductive portion 1224 is arranged around the magnetic sensing component 1222 , and the second conductive portion 1226 is arranged around the first conductive portion 1224 . In this way, regardless of the direction in which the first adapter 120 is inserted, the terminal 1204 can be electrically connected to the first conductive part 1224, and the terminal 1206 can be electrically connected to the second conductive part 1226, so as to respectively transmit correct corresponding voltage. That is to say, the access of the first adapter base 120 is not directional.
