The two inclined surfaces on the connecting blocks cooperate with the inclined surfaces on the two trapezoidal blocks, so that the two trapezoidal blocks move away from each other. The spring is compressed and deformed. As the male connector continues to move, the elastic force of the spring finally drives the trapezoidal blocks to move, so that the trapezoidal blocks are placed in the positioning slots, thereby positioning the male connector. While achieving quick connection, it can prevent the male connector from detaching from the female connector and ensure the stability of the insertion.

[0014] (2) Press the two fixed blocks toward the shell, drive the guide push rod and the connecting block to move through the fixed blocks, and drive the two mounting blocks to move through the two transmission plates, so that the two trapezoidal blocks move away from each other. When the trapezoidal blocks are disengaged from the positioning slots, the male connector and the female connector can be directly separated, which is simple and convenient to operate.

[0023] like Figure 1-5 As shown, a cable quick connection mechanism comprises a first cable body 1 and a second cable body 2, a male connector 3 is arranged at the right end of the first cable body 1, and a female connector 4 is arranged at the left end of the second cable body 2, the male connector 3 is plugged into the female connector 4, the front and rear end faces of the male connector 3 are fixedly connected with connecting plugs 5, symmetrically distributed positioning slots 6 are opened on the connecting plugs 5, and a symmetrically distributed shell 7 is fixedly connected to the female connector 4, the shell 7 is made of transparent material, and an opening 17 is opened on the left side wall of the shell 7, a symmetrically arranged guide sleeve 8 is fixedly connected to the inner wall of the shell 7, a connecting rod 9 is slidably connected in the guide sleeve 8, and a trapezoidal block 10 is fixedly connected to one end of the connecting rod 9 outside the guide sleeve 8, with the movement of the connecting plug 5, the two inclined surfaces on the connecting plug 5 cooperate with the inclined surfaces on the two trapezoidal blocks 10, so that the two relative trapezoidal blocks 10 can be moved away from each other, a spring 11 sleeved outside the guide sleeve 8 is fixedly connected between the inner wall of the shell 7 and the trapezoidal block 10, and the spring 11 is When the positioning slot 6 is opposite to the trapezoidal block 10, the trapezoidal block 10 is driven to move by the elastic force of the spring 11, so that the trapezoidal block 10 is inserted into the positioning slot 6. A connecting block 13 is provided inside the shell 7. A symmetrically arranged transmission plate 14 is hinged on the connecting block 13. One end of the two transmission plates 14 away from the connecting block 13 is hinged to the two mounting blocks 12 respectively. A guide push rod 15 is fixedly connected to the middle part of the right side wall of the connecting block 13. The right end face of the trapezoidal block 10 is fitted with the inner wall of the positioning slot 6. At this time, the male connector 3 and the female connector 4 are completely plugged in. The four trapezoidal blocks 10 cooperate with the four positioning slots 6 to position the male connector 3. While achieving quick connection, it can prevent the male connector 3 from detaching from the female connector 4 to ensure the stability of the connection. The right end of the guide push rod 15 is fixedly connected with a fixing block 16.

[0024] like Figure 1 As shown, the male connector 3 is matched with the female connector 4 .

[0025] like Figure 1 As shown, the two connecting plugs 5 are symmetrically arranged about the central axis of the male connector 3.

[0026] like Figure 3 As shown, two trapezoidal blocks 10 are in contact.

[0027] like Figure 2 and Figure 3 As shown, the guide push rod 15 movably penetrates the side wall of the housing 7 , and the connecting block 13 can be guided by the guide push rod 15 .

[0028] like Figure 1 As shown, the two housings 7 are symmetrically arranged about the central axis of the female connector 4 .

[0029] like Figure 3 As shown, the right end of the connecting block 5 is a triangle. As the connecting block 5 moves, the two inclined surfaces on the connecting block 5 cooperate with the inclined surfaces on the two trapezoidal blocks 10, so that the two opposite trapezoidal blocks 10 can be moved away from each other.

[0030] Working principle: the male connector 3 is inserted into the female connector 4. During this process, the two connecting blocks 5 are respectively located in the two housings 7 through the two openings 17. As the connecting blocks 5 move, the two inclined surfaces on the connecting blocks 5 cooperate with the inclined surfaces on the two trapezoidal blocks 10, so that the two relative trapezoidal blocks 10 can be moved away from each other. The spring 11 is compressed and deformed under force. Through the action of the spring 11, the end of the trapezoidal block 10 away from the connecting rod 9 is always in contact with the connecting block 5. When the positioning slot 6 is opposite to the trapezoidal block 10, the elastic force of the spring 11 drives the trapezoidal block 10 to move, so that the trapezoidal block 10 is inserted into the positioning slot 6, and the right end face of the trapezoidal block 10 is aligned with the inner wall of the positioning slot 6. When the male connector 3 and the female connector 4 are in close contact with each other, the two fixing blocks 16 are pressed toward the shell 7, and the guide push rod 15 and the connecting block 13 are driven to move by the fixing blocks 16, and the two mounting blocks 12 are driven to move by the two transmission plates 14, so that the two trapezoidal blocks 10 are relatively far away from each other. When the trapezoidal block 10 is detached from the positioning slot 6, the male connector 3 and the female connector 4 can be directly separated, and the overall operation is simple and convenient.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
