As shown in Figures 1 to 5, the plug electrical connector 1 can be, for example, a DC power plug electrical connector and is used for docking with various DC power socket electrical connectors. The plug electrical connector 1 includes a shell 11, an outer pipe 12, an inner pipe 13, a conductive terminal 14 and a locking member 15. The outer pipe 12 is fixedly arranged on the shell 11, and the inner pipe 13 is at least partially arranged inside the outer pipe 12 and can be extended in a direction E relative to the outer pipe 12. Or move in the retracting direction R opposite to the protruding direction E, the conductive terminal 14 is at least partly fixedly arranged in the inner pipe member 13 and can move with the inner pipe member 13, and the locking member 15 is rotatably arranged on the outer pipe member 12 and is used to lock each other with the locking member (not shown in the figure) of the socket electrical connector.

In this embodiment, as shown in FIG. 3 to FIG. 5 , the inner pipe member 13 is formed with two first moving matching structures 131 , and the outer pipe member 12 is formed with two second moving matching structures 121 respectively corresponding to the two first moving matching structures 131 .

For example, in another embodiment, the inner tube can be formed with one or more first movement fit structures, and the outer tube can be formed with one or more second movement fit structures, wherein the first movement fit structures can be slots and the second movement fit structures can be protrusions.

In addition, as shown in Figures 3 to 5, the outer pipe member 12 is formed with a first rotational engagement structure 122, and the lock member 15 is formed with a second rotational engagement structure 151 corresponding to the first rotational engagement structure 122 and a locking structure 152. 22 and the second rotating fitting structure 151 can rotate relative to each other, and the locking structure 152 is used to lock with the matching locking structure (not shown in the figure) of the matching lock member. Specifically, the first rotational engagement structure 122 can be an annular flange, the second rotational engagement structure 151 can be an annular groove, and the locking structure 152 can be an internal thread, but the invention is not limited to this embodiment. For example, in another embodiment, the outer pipe member may be formed with a plurality of first rotational engagement structures arranged along the long axis direction of the outer pipe member, and the lock member may be formed with a plurality of second rotational engagement structures arranged along the long axis direction of the lock member, wherein the first movement engagement structure may be an arc-shaped protrusion, the second movement engagement structure may be an arc-shaped groove, and the locking structure may be an external thread.

Furthermore, as shown in Fig. 3 to Fig. 5, the electrical plug connector 1 further includes a A first conductive element 16 of an electrical signal source (not shown in the figure), a second conductive element 17 electrically connected to a second electrical signal source (not shown in the figure) different from the first electrical signal source, and an insulator 18. Specifically, the first electrical signal source and the second electrical signal source can be, for example, a negative signal source and a positive signal source respectively, and the first conductive element 16 and the second conductive element 17 can be, for example, two wires respectively. The first conductive element 16 and the outer pipe 12 are electrically connected to each other, the inner pipe 13 and the outer pipe 12 are electrically connected to each other, the second conductive element 17 is electrically connected to the conductive terminal 14, and the insulating member 18 is arranged between the conductive terminal 14 and the inner pipe 13 and is used to fix the conductive terminal 14 on the inner pipe 13 and prevent the conductive terminal 14 and the inner pipe 13 from being electrically connected to each other.

For example, in another embodiment, the two ends of the elastic member can be respectively connected to the outer pipe member and the inner pipe member.

Please refer to FIG. 6 to FIG. 9. FIG. 6 and FIG. 7 are schematic diagrams of the electrical plug connector 1 of the present invention when it is in different states relative to a first electrical socket connector 21. FIG. 8 and FIG. As shown in FIG. 6 to FIG. 9 , the electrical plug connector 1 can be used not only for the first electrical receptacle connector 21 with a longer length, but also for the second electrical receptacle connector 22 with a shorter length. As shown in Figures 6 and 7, since the length of the first socket electrical connector 21 and the length of the plug electrical connector 1 match each other, when the plug is electrically connected When the locking part 15 of the device 1 and a matching lock part 211 of the first socket electrical connector 21 are not locked with each other, the conductive terminal 14 of the plug electrical connector 1 and a conductive mating terminal 212 of the first socket electrical connector 21 are not completely butted (that is, the end of the conductive terminal 14 of the plug electrical connector 1 has not yet abutted against a bottom 213 of the conductive mating terminal 212 of the first socket electrical connector 21). At this time, the user can lock the plug electrical connector 1 by rotating the locking part 15 The locking part 15 and the locking part 211 of the first socket electrical connector 21 are locked to each other, thereby driving the plug electrical connector 1 to switch from the state shown in FIG. 6 to the state shown in FIG. The end portion of the first electrical receptacle connector 21 abuts against the bottom 213 of the conductive mating terminal 212 ), and the locking member 15 of the plug electrical connector 1 and the locking member 211 of the first receptacle electrical connector 21 are locked to each other. It is worth noting that since the length of the first socket electrical connector 21 matches the length of the plug electrical connector 1, the inner pipe member 13 and the conductive terminal 14 do not move relative to the outer pipe member 12 when the plug electrical connector 1 is switched from the state shown in FIG. 6 to the state shown in FIG. Member 19 is not elastically compressed.

As shown in Figures 8 and 9, since the length of the second socket electrical connector 22 is shorter than the length of the plug electrical connector 1, when the locking member 15 of the plug electrical connector 1 and a locking member 221 of the second socket electrical connector 22 abut against each other but have not yet locked each other, the conductive terminal 14 of the plug electrical connector 1 and a conductive mating terminal 222 of the second socket electrical connector 22 have been completely butted (that is, the end of the conductive terminal 14 of the plug electrical connector 1 has abutted against the second socket electrical connector 2 2), when the user rotates the locking member 15 to lock the locking member 15 of the plug electrical connector 1 and the locking member 221 of the second socket electrical connector 22, the inner pipe member 13 and the conductive terminal 14 will move in the retracting direction R relative to the outer pipe member 12 (that is, the inner pipe member 13 and the conductive terminal 14 do not move relative to the second socket electrical connector 22, and the shell member 11, lock The member 15 and the outer pipe member 12 move relative to the second socket electrical connector 22 along the docking direction D) to elastically compress the elastic member 19, and then drive the plug electrical connector 1 to switch from the state shown in FIG. 8 to the state shown in FIG. Docking (that is, the end of the conductive terminal 14 of the plug electrical connector 1 abuts against the bottom 223 of the conductive mating terminal 222 of the second electrical socket connector 22), and the locking member 15 of the plug electrical connector 1 and the matching locking member 221 of the second electrical socket connector 22 are locked to each other, and the elastic member 19 is in a compressed state.

Understandably, in another usage scenario, if the conductive terminal 14 of the electrical plug connector 1 has abutted against the bottom of the conductive mating terminal of the third electrical receptacle connector but the locking member 15 of the electrical plug connector 1 is still separated from the locking member of the third electrical receptacle connector, the user can first apply force to the electrical plug connector 1 to make the inner tube 13 and the conductive terminal 14 move a predetermined distance relative to the outer tube 12 along the retracting direction R, so that the locking member 15 of the plug electrical connector 1 approaches and abuts against the third electrical connector. The locking part of the socket electrical connector, and then by rotating the locking part 15, the locking part 15 of the plug electrical connector 1 and the matching locking part of the third socket electrical connector are locked to each other, thereby completing the docking of the plug electrical connector 1 and the third socket electrical connector.

Compared with the prior art, when the electric plug connector of the present invention is docked with various electrical socket connectors of different lengths, the movement of the inner tube and the conductive terminal relative to the outer tube can be used to allow the locking parts of the plug electrical connector to approach and lock with the matching lock parts of various electrical socket connectors of different lengths, thereby completing the docking of the plug electrical connector and various electrical socket connectors of different lengths. Therefore, the electrical plug connector of the present invention has higher commonality.
