[0024] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Reference Figure 1 As shown, the utility model provides a hole connector 100, which is used to connect with a female connector (not shown in the figure) and a terminal (not shown in the figure). The first end of the hole connector 100 is provided with a connecting hole 101, and the connecting hole 101 can be connected with the terminal. The hole connector 100 is provided with an unlocking member 102, and the unlocking member 102 is used to disengage the hole connector 100 from the female connector, wherein:

[0026] A first locking piece 10 is also provided on the hole connector 100, and the first locking piece 10 can move along a first path, and the first path is a moving trajectory of the first locking piece 10 approaching or moving away from the hole connector 100. When the first locking piece 10 moves to the end of the first path, the terminal is locked with the hole connector 100; a second locking piece 20 is provided at the second end of the hole connector 100, and the second locking piece 20 can move along a second path, and the second path is a moving trajectory of the second locking piece 20 approaching or moving away from the unlocking piece 102. When the second locking piece 20 moves to the end of the second path, the second locking piece 20 abuts against the unlocking piece 102.

[0027] In the embodiment provided in the present application, one end of the hole connector 100 is connected to the terminal, and the other end is connected to the female connector. After the terminal is inserted into the connecting hole 101 and connected with the hole connector 100, the terminal may fall out of the connecting hole 101 due to reasons such as loose connection. Therefore, a first locking piece 10 is provided on the hole connector 100. When the terminal is inserted into the connecting hole 101, the first locking piece 10 is moved to the end of the first path so that the terminal can be locked in the connecting hole 101. When the terminal needs to be removed from the connecting hole 101, the first locking piece 10 can be moved to the starting end of the first path, and then the terminal can be pulled out of the connecting hole 101.

[0028] The unlocking member 102 of the present application is a spring sheet, which is arranged on the hole connector 100. When the female connector is connected to the hole connector 100, the female connector and the hole connector 100 can be separated by pressing the spring sheet. However, during operation, the female connector and the hole connector 100 are often separated due to mispressing the spring sheet, thereby causing the connection of the automotive electrical appliances to be interrupted. Therefore, after the female connector and the hole connector 100 are connected, the second locking member 20 is moved to the end of the second path, and the second locking member 20 abuts against the spring sheet, so that the spring sheet cannot be pressed, thereby ensuring that the connection between the female connector and the hole connector 100 is locked. When the female connector and the hole connector 100 need to be separated, the second locking member 20 is moved to the starting end of the second path to release the displacement restriction of the spring sheet. At this time, pressing the unlocking member 102 can separate the female connector and the hole connector 100.

[0029] Reference Figure 1 as well as Figure 2 As shown, the first end of the first locking member 10 is connected to the hole connector 100, and the second end of the first locking member 10 can move along the first path. The outer wall of the connecting hole 101 facing the first locking member 10 is provided with a limiting protrusion 103. When the first locking member 10 moves to the end of the first path, the second end of the first locking member 10 abuts against the limiting protrusion 103. In the embodiment provided in the present application, the first end of the first locking member 10 is integrally formed with the hole connector 100, and the first locking member 10 is arranged on the hole connector 100 in an inclined posture. The first path is an arc trajectory with the connection between the first end of the first locking member 10 and the hole connector 100 as the center and the first locking member 10 as the radius. The second end of the first locking member 10 moves along the first path toward the direction approaching the limiting protrusion 103 until it passes the limiting protrusion 103 and reaches the end of the first path. At this time, the second end of the first locking member 10 abuts against the bottom of the limiting protrusion 103, and the first locking member 10 cannot move toward the starting end of the first path, thereby achieving locking the terminal in the connecting hole 101.

[0030] Furthermore, in order to improve the locking effect of the first locking member 10, a fixing hook 11 is provided on the side of the second end of the first locking member 10 away from the limiting protrusion 103, and a fixing boss 104 is provided on the hole connector 100. When the second end of the first locking member 10 moves to the end of the first path, the fixing hook 11 is engaged with the fixing boss 104. When the second end of the first locking member 10 abuts against the bottom of the limiting protrusion 103, the fixing hook 11 is engaged with the fixing boss 104, which can further improve the locking effect of the first locking member 10. Under the action of the double locking structure, the terminal can be stably connected to the connecting hole 101, which is conducive to improving the connection effect between the hole connector 100 and the terminal.

[0031] In a feasible implementation mode, referring to Figure 2 As shown in the figure, the movement process of the second end of the first locking member 10 is the process in which the side surface of the second end of the first locking member 10 changes from an inclined state to a vertical state. In the process of crossing the limiting protrusion 103, the end of the limiting protrusion 103 will abut against the side surface of the second end of the first locking member 10. In order to make the whole process smoother, the second end of the first locking member 10 is Figure 2 Contact bevels 12 are provided at the upper and lower ends. When the limiting protrusion 103 abuts against the contact bevel 12 at the lower portion, it is convenient for the second end of the first locking piece 10 to continue to move downward. When the first locking piece 10 is about to reach the end of the first path, the side surface of the second end of the first locking piece 10 is close to a vertical state, and the abutting force between the limiting protrusion 103 and the second end of the first locking piece 10 is relatively large. Under the action of the contact bevel 12 at the upper portion of the second end of the first locking piece 10, the abutting force can be weakened, thereby enabling the first locking piece 10 to smoothly pass over the limiting protrusion 103, thereby locking the terminal and the connecting hole 101.

[0032] Reference Figures 3 to 6 As shown, the second locking member 20 includes an abutment block 21 and a guide groove 22, and the hole connector 100 is provided with a connecting member 30, and the connecting member 30 is provided with a guide strip 31 that cooperates with the guide groove 22. When the second locking member 20 moves to the end of the second path, the abutment block 21 abuts against the unlocking member 102. In the embodiment provided by the present application, the connecting member 30 is integrally formed and connected to the hole connector 100, and the second path is Figure 6 The second locking member 20 moves up and down along the trajectory. Under the cooperation of the guide bar 31 and the guide groove 22, the second locking member 20 moves up and down to approach or move away from the unlocking member 102. When the second locking member 20 moves up to the abutment block 21 and abuts against the unlocking member 102, it reaches the end of the second path. Under the action of the second locking member 20, the unlocking member 102 cannot be pressed, which can effectively avoid the separation of the female connector and the female connector 100 due to the wrong pressing of the unlocking member 102, thereby ensuring the stable connection between the female connector and the female connector 100.

[0033] Further, the second locking member 20 is provided with a first positioning protrusion 23, and a positioning groove 32 is provided on one side of the connecting member 30. When the second locking member 20 moves to the end of the second path, the first positioning protrusion 23 is located in the positioning groove 32. Figure 6As shown, the first positioning protrusion 23 is arranged at the lower part of the second locking member 20. When the second locking member 20 reaches the end of the second path, the position of the second locking member 20 needs to be fixed to achieve the abutment and locking with the unlocking member 102. As the second locking member 20 moves upward, the first positioning protrusion 23 moves upward to reach the positioning groove 32, and the position of the second locking member 20 is fixed in cooperation with the positioning groove 32. When the female connector and the female connector 100 need to be separated, the second locking member 20 is moved downward to make the first positioning protrusion 23 disengage from the positioning groove 32, release the abutment of the abutment block 21 and the unlocking member 102, and then press the unlocking member 102 to achieve the separation.

[0034] When the second locking piece 20 moves to the starting end of the second path, in order to facilitate the next locking, the second locking piece 20 can be fixed at the starting end of the second path without removing the second locking piece 20. Therefore, a first supporting boss 33 and a second supporting boss 34 are provided on opposite sides of the connecting piece 30, and a second positioning boss 24 is also provided on the second locking piece 20. When the second locking piece 20 is located at the initial end of the second path, the first positioning boss 23 abuts against the first supporting boss 33, and the second positioning boss 24 abuts against the second supporting boss 34. The first supporting boss 33 and the second supporting boss 34 are both arranged on opposite sides of an end of the connecting member 30 away from the unlocking member 102, and the second positioning protrusion 24 is arranged on a side of the second locking member 20 opposite to the first positioning protrusion 23. When the second locking member 20 is located at the initial end of the second path, the first supporting boss 33 supports the first positioning protrusion 23, and the second supporting boss 34 supports the second positioning protrusion 24. Under the common supporting action of both sides, the second locking member 20 can be stably connected to the starting end of the second path. After the female connector is connected to the female connector 100, the second locking member 20 is moved up again to the abutment block 21 to abut against the unlocking member 102.
