[0045] Please refer to Figures 4 to 9As shown, in an embodiment of the utility model, the unlocking spring 8 is made of metal material, and is substantially U-shaped. The unlocking spring 8 includes a fixed part 81, a lock catch part 82 arranged at intervals with the fixed part 81, a connecting part 83 connecting one end of the fixed part 81 and one end of the lock catch part 82, and a stress part 84 connected with the lock catch part 82. In the embodiment shown in the utility model, the fixed part 81, the connecting part 83 and the lock catch part 82 are U-shaped as a whole. The fixed part 81 and the lock catch part 82 are located on the same side of the connecting part 83. The fixed part 81 is fixed in the mounting groove 4421 of the first body 4. The lock catch part 82 is provided with at least one lock catch protrusion 821, which is configured to be locked with the lock catch hole 311 of the docking connector 100. In the embodiment shown in the utility model, the lock catch protrusion 821 is two, and is arranged at intervals along the first direction A1-A1. In the embodiment shown in the utility model, the two lock catch protrusions 821 are integrally punched from the lock catch part 82, and the two lock catch protrusions 821 are arranged in alignment along the first direction A1-A1. The stress part 84 can directly or indirectly drive the lock catch part 82 to move close to the fixed part 81 under the action of external force, so that the lock catch protrusion 821 is separated from the lock catch hole 311 of the docking connector 100, to realize unlocking. In the embodiment shown in the utility model, the connecting part 83 is arc-shaped, to better support the deformation of the lock catch part 82.

[0046] In the embodiment shown in the utility model, the lock catch part 82 is arranged at intervals with the fixed part 81, wherein the lock catch part 82 is located above the fixed part 81. The unlocking spring 8 includes a space 80 between the lock catch part 82 and the fixed part 81. The unlocking spring 8 further includes a reset spring arm 85 extending at least partially into the space 80, which is configured to drive the lock catch part 82 to move away from the fixed part 81 to realize the reset of the lock catch part 82.

[0047] Please refer to Figure 8 As shown, in the first embodiment of the utility model, the reset spring arm 85 is integrally punched from the lock catch part 82, and the reset spring arm 85 is configured to abut against the fixed part 81 to provide a reset force to realize the reset of the lock catch part 82.

[0048] Please refer to Figure 10 As shown, in the second embodiment of the utility model, the reset spring arm 85 is integrally punched from the fixed part 81, and the reset spring arm 85 is configured to abut against the lock catch part 82 to provide a reset force to realize the reset of the lock catch part 82.

[0049] In the embodiment shown in the utility model, the reset spring arm 85 extends obliquely away from the connecting portion 83. The reset spring arm 85 is cantilever-shaped, and includes an arc-shaped contact surface 851 near the free end thereof. The arc-shaped contact surface 851 is used to abut against the fixed portion 81 in the first embodiment described above, or to abut against the locking portion 82 in the second embodiment described above, so as to reduce scratching and improve the smoothness of abutment as much as possible.

[0050] In the embodiment shown in the utility model, the reset spring arm 85 is located between the two locking protrusions 821 in the first direction A1-A1 (for example, the left-right direction). The two locking protrusions 821 are misaligned with the reset spring arm 85 along the first direction A1-A1. In other words, the locking protrusions 821 and the reset spring arm 85 are arranged in front of and behind each other along the second direction A2-A2 (for example, the front-back direction), and the second direction A2-A2 is perpendicular to the first direction A1-A1.

[0051] Specifically, in the embodiment shown in the utility model, the force receiving portion 84 includes an inclined portion 841 connected to the locking portion 82 and an extension portion 842 connected to the inclined portion 841. The unlocking spring piece 8 includes an opening 8410 left after the reset spring arm 85 is formed by stamping, the opening 8410 is located at the junction of the locking portion 82 and the inclined portion 841, and the opening 8410 is located on the locking portion 82 and the inclined portion 841. In this way, the length of the reset spring arm 85 can be adjusted by using the inclined portion 841.

[0052] When unlocking is needed, an external force can be transmitted to the force receiving portion 84 by pulling the pull strap 9, the force receiving portion 84 drives the locking portion 82 to move close to the fixed portion 81 (for example, elastically deformed downward), so that the locking protrusions 821 are separated from the locking hole 311 of the docking connector 100, to achieve unlocking. At this time, the reset spring arm 85 is compressed to generate a certain restoring force on the locking portion 82. When unlocking is completed and the external force is removed, the reset spring arm 85 resets, thereby driving the locking portion 82 to reset.

[0053] Of course, those skilled in the art can understand that in other embodiments of the utility model electric connector 200, the pull strap 9 can also not be provided. When unlocking, the external force directly acts on the force receiving portion 84, and the purpose of the utility model can also be achieved.

[0054] The person skilled in the art can understand that the reset elastic arm 85 is arranged, on one hand, to avoid fatigue failure of the locking buckle part 82 caused by excessive pulling of the locking buckle part 82 by external force during unlocking; on the other hand, to better reset the locking buckle part 82 when the external force is removed.

[0055] The above implementation manners are only used for describing the utility model and not limiting the technical solutions described by the utility model, and the understanding of the utility model should be based on the person skilled in the art, and although the utility model has been described in detail in the specification with reference to the above implementation manners, the person skilled in the art should understand that the person skilled in the art can still modify or equivalently replace the utility model, and all the technical solutions and improvements which do not deviate from the spirit and scope of the utility model should be covered in the claim range of the utility model.
