[0041] Embodiment 2

[0042] As shown in Figure 5 and Figure 6As shown, different from the embodiment 1, the connector for wire connection in the modular building of the embodiment comprises a locking mechanism 8 and an unlocking mechanism 9.

[0043] Specifically, the inner wall of the male head 1 is provided with an annular collar 12. The locking mechanism 8 is installed on the outer wall of the male head 1, and the unlocking mechanism 9 is vertically movably embedded on the outer wall of the female head 2. When the locking mechanism 8 is locked, the male head 1 is inserted into the female head 2, and the locking mechanism 8 is clamped with the annular collar 12, so that the current of another male head 1 is transmitted to the female head 2, and the female head 2 transmits the current to the male head 1 through the terminal post and the plurality of wires 3. When the locking mechanism 8 is unlocked, the unlocking mechanism 9 can vertically move and push the locking mechanism 8, so that the locking mechanism 8 is separated from the annular collar 12. By setting the locking mechanism 8 and clamping it with the annular collar 12 on the inner wall of the male head 1, the tight connection between the male head 1 and the female head 2 is ensured, which prevents accidental loosening caused by external vibration or impact, greatly improves the safety and stability of electrical connection. Moreover, through the threaded connection between the first threaded sleeve 51 and the male head 1, a double connection mode is formed, which further enhances the reliability of the male head 1 and the female head 2 when they are docked. By setting the unlocking mechanism 9, it can realize the unlocking between the male head 1 and the female head 2, which simplifies the operation process, reduces the time and difficulty of installation and disassembly, and improves the work efficiency.

[0044] More specifically, the locking mechanism 8 comprises a clamping block 81 and a first elastic member 82. One end of the clamping block 81 is hinged to the outer wall of the male head 1, which allows it to swing freely within a certain range, ensuring smooth clamping and disengaging process and reducing mechanical wear. The other end of the clamping block 81 can be clamped with the annular clamping ring 12, which ensures the tight connection between the male head 1 and the female head 2 and prevents accidental loosening due to external vibration or impact. The two ends of the first elastic member 82 are connected with the outer wall of the male head 1 and the bottom wall of the clamping block 81, respectively. The unlocking mechanism 9 comprises a pushing column 91, a fourth limiting ring 92 and a plurality of second elastic members 93. The outer wall of the female head 2 is provided with a pushing space 22, the pushing column 91 penetrates through the outer wall of the female head 2, the fourth limiting ring 92 is sleeved on the pushing column 91, and the two ends of the plurality of second elastic members 93 are connected with the bottom wall of the fourth limiting ring 92 and the bottom wall of the pushing space 22, respectively. When the male head 1 is locked with the female head 2, the clamping block 81 is clamped with the annular clamping ring 12. When the male head 1 is unlocked with the female head 2, the pushing column 91 can move vertically and push the clamping block 81 to make the clamping block 81 disengage from the annular clamping ring 12. By arranging the first elastic member 82 and the second elastic member 93, the action flexibility of the clamping block 81 and the pushing column 91 can be ensured, which not only provides buffer when stressed and prolongs the service life of the components, but also enables the first elastic member 82 and the second elastic member 93 to provide elastic force to the clamping block 81 and the fourth limiting ring 92, respectively, when the pushing column 91 pushes the clamping block 81 to disengage from the annular clamping ring 12, i.e. when unlocked, so as to reset the clamping block 81 and the pushing column 91. That is, when the male head 1 is being connected with the female head 2, the male head 1 is aligned with the female head 2 through the guide slot 7 or the guide column 6 and the two or three insertion holes, and the female head 2 is aligned with the male head 1 through the guide column 6 or the guide slot 7 and the two or three insertion columns, and the male head 1 moves along the axis of the female head 2 into the female head 2. When the clamping block 81 touches the annular clamping ring 12, the first elastic member 82 is compressed, the clamping block 81 rotates around the axis of the hinge between the clamping block 81 and the outer wall of the male head 1 towards the direction of the male head 1, until the clamping block 81 passes through the annular clamping ring 12. When the clamping block 81 is clamped on the annular clamping ring 12, the first elastic member 82 rebounds, and at this time the clamping block 81 is located directly below the pushing column 91, so that the male head 1 is clamped in the female head 2, and then the male head 1 is screwed with the first threaded sleeve 51 through the screw thread on the male head 1, to realize double fixation. When it is needed to pull out the male head 1 from the female head 2, first, the first threaded sleeve 51 is unscrewed from the screw thread on the male head 1, then the pushing column 91 is pressed to make the one end of the pushing column 91 vertically descend towards the clamping block 81 and push the clamping block 81, and the fourth limiting ring 92 vertically descends in the pushing space 22 along with the movement of the pushing column 91, so that the clamping block 81 disengages from the annular clamping ring 12. At this time, the clamping block 81 presses the first elastic member 82, and the fourth limiting ring 92 presses the second elastic member 93 along with the pushing column 91, and the first elastic member 82 and the second elastic member 93 are both in the compressed state. Finally, the male head 1 is pulled out of the female head 2 through the guide of the guide column 6 or the guide slot 7, and the unlocking of the male head 1 and the female head 2 is completed. Preferably, the outer contour of the clamping block 81 clamped with the annular clamping ring 12 can beFigure 6 The outer wall of the clamping block 81 at the inner wall of the female head 2 can be a plane, a curved surface or other suitable surface that matches the shape of the inner wall of the female head 2. It should be noted that the clamping block 81 is not limited to the above shape, and can also be other shapes suitable for the present embodiment, which will not be described here.

[0045] Further, the locking mechanism 8 and the unlocking mechanism 9 are provided in plurality, and the plurality of locking mechanisms 8 and the plurality of unlocking mechanisms 9 are one-to-one corresponding, and the plurality of locking mechanisms 8 can be clamped with the annular clamping ring 12. The plurality of locking mechanisms 8 are arranged on the outer wall of the male head 1 in the circumferential direction around the axis of the male head 1, and the plurality of unlocking mechanisms 9 are embedded in the outer wall of the female head 2 in the circumferential direction around the axis of the female head 2, which can make the male head 1 and the female head 2 more uniform under stress in the locked state, and improve the overall mechanical properties. And it can also effectively resist external vibration or impact force, and enhance the durability and reliability of the system.

[0046] It should be noted that when the male head 1 and the female head 2 are locked, the plurality of locking mechanisms 8 are clamped with the annular clamping ring 12 at the same time, realizing one-time locking. When the male head 1 and the female head 2 are unlocked, the plurality of unlocking mechanisms 9 are pressed at the same time, so that the plurality of clamping blocks 81 in the plurality of locking mechanisms 8 are simultaneously separated from the annular clamping ring 12, realizing one-time unlocking, so that the locking and unlocking of the male head 1 and the female head 2 are more convenient and fast.
