[0046] Embodiment 1:

[0047] As Figures 1 to 4As shown in the figure, the electrical connector provided in this embodiment includes an insulating housing 1 and a locking member 2. The insulating housing 1 has a docking portion 111, and the locking member 2 is disposed on the docking portion 111. The locking member 2 has a plurality of locking points 21. Among the plurality of locking points 21, the linear distance between the leftmost outer side surface of the leftmost locking point 21 and the rightmost outer side surface of the rightmost locking point 21 is d, and the linear distance between the leftmost outer side surface and the rightmost outer side surface of the docking portion 111 is D, and d:D = 0.50. In other embodiments, it can also be 0.45, 0.70, 0.95, etc. By limiting the ratio of d to D, regardless of the length of the docking portion 111, the corresponding locking member 2 can be adapted, ensuring the stability of the locking member 2 when the electrical connector is connected to the docking connector 7.

[0048] Among them, the locking member 2 further includes a first fixing portion 22, a first connecting arm 23, and a first pressing portion 24. The first fixing portion 22 is installed on the insulating housing 1. The first connecting arm 23 is bent, and one end is connected to the first fixing portion 22, and the other end is connected to the first pressing portion 24. The locking points 21 are disposed on the first pressing portion 24. The rear side of the first pressing portion 24 has a first extending portion 25 that bends upward. The first extending portion 25 has a first through hole 26 for the pulling belt 5 to pass through. The connection between the locking member 2 and the insulating housing 1 is realized through the first fixing portion 22. When unlocking, press the first pressing portion 24 so that the locking points 21 move downward away from the locking position 71 of the docking connector 7, and then the electrical connector can be pulled out.

[0049] Among them, it further includes a circuit board 3, a cable 4, and a pulling belt 5. The circuit board 3 is disposed inside the insulating housing 1. The cable 4 is electrically connected to the circuit board 3 and passes out of the insulating housing 1. One end of the pulling belt 5 passes through the insulating housing 1 and the first through hole 26 and is connected to the other end of the pulling belt 5. The unlocking method using the pulling belt 5 is more convenient.

[0050] Among them, the insulating housing 1 includes a first housing 11 and a second housing 12 that is snap-connected to the first housing 11. An anti-insertion portion 112 and a docking portion 111 protrude forward from the first housing 11. The anti-insertion portion 112 plays a role in preventing oblique insertion.

[0051] Among them, the second housing 12 extends backward to form a protruding portion 121. The protruding portion 121 has a third through hole 122. The first through hole 26 is located obliquely above the third through hole 122. One end of the pulling belt 5 passes through the third through hole 122 and the first through hole 26, and is folded back through the third through hole 122 and then connected to the other end of the pulling belt 5. Through the settings of the first through hole 26 and the third through hole 122, when the pulling belt 5 is pulled backward, the pulling force is divided into a downward pulling force and a backward pulling force. Only by pulling the pulling belt 5 backward, the actions of unlocking the locking member 2 and detaching the electrical connector from the docking connector 7 can be achieved, without the need for two steps, which is more efficient.

[0052] Embodiment 2:

[0053] As Figure 5 shown, this embodiment provides a connector assembly, including the electrical connector of Embodiment 1 and a docking connector 7 electrically connected to the electrical connector. The docking connector 7 has a locking position 71 that cooperates with the locking member 2.

[0054] Embodiment 3:

[0055] As Figures 6 to 9 shown, this embodiment provides an electrical connector, including an insulating housing 1 and a locking member 2. The insulating housing 1 has a docking portion 111, and the locking member 2 is disposed on the docking portion 111. The locking member 2 includes a first pressing portion 24, a second pressing portion 27, and a plurality of locking points 21. The first pressing portion 24 and the second pressing portion 27 are separately provided, and the plurality of locking points 21 are at least disposed on the second pressing portion 27. In this embodiment, two locking points 21 are provided on the first pressing portion 24, and one locking point 21 is provided on each of the left and right second pressing portions 27. In other embodiments, the locking points may be only provided on the second pressing portion 27. Among the plurality of locking points 21, the linear distance between the leftmost outer side surface of the leftmost locking point 21 and the rightmost outer side surface of the rightmost locking point 21 is d, and the linear distance between the leftmost outer side surface and the rightmost outer side surface of the docking portion 111 is D, and d:D = 0.45 - 0.95. The leftmost locking point 21 and the rightmost locking point 21 are both disposed on the second pressing portion 27, and the first pressing portion 24 is located between the leftmost locking point 21 and the rightmost locking point 21. Through the settings of the first pressing portion 24 and the second pressing portion 27, it is applicable not only to the traditional docking connector 7 (with only one set of locking positions 71), but also to the docking connector 7 that can cooperate with the locking points 21 of the first pressing portion 24 and the second pressing portion 27. When connected to the traditional docking connector 7, since the first pressing portion 24 and the second pressing portion 27 are separately provided, the locking points 21 of the first pressing portion 24 cooperate with the locking positions 71 of the docking connector 7, and the locking points of the second pressing portion 27 abut against the inner wall of the docking connector 7. The second pressing portion 27 does not affect the cooperation between the locking points 21 of the first pressing portion 24 and the locking positions 71 of the docking connector 7. It not only retains the traditional structure of the locking member 2 for pressing and the locking points 21, but also has an additional second pressing portion 27, and defines the relationship between the locking points 21 and the docking portion 111 on the second pressing portion 27. Through the settings of the first pressing portion 24, the second pressing portion 27, and the locking points 21, double locking is adopted, combined with the limitation of the ratio of d and D, greatly improving the connection stability between the electrical connector and the docking connector 7.

[0056] Among them, the locking fastener 2 further includes a first fixing portion 22, a first connecting arm 23, and a second connecting arm 28. The first fixing portion 22 is installed on the insulating housing 1. The first connecting arm 23 is bent, with one end connected to the first fixing portion 22 and the other end connected to the first pressing portion 24. Second connecting arms 28 are connected to both the left and right ends on the front side of the first fixing portion 22. The second connecting arms 28 are bent, with one end connected to a second pressing portion 27. The first pressing portion 24 is located between the two second pressing portions 27 on the left and right. A first extending portion 25 that bends upward is provided on the rear side of the first pressing portion 24. The first extending portion 25 has a first through hole 26 for connecting with the pulling belt 5. A second extending portion 29 that bends upward is provided on the rear side of the second pressing portion 27. The two second extending portions 29 on the left and right are connected by a connecting portion 210. In this embodiment, the connecting portion 210 is integrally connected to the second extending portion 29. The connecting portion 210 is located below the top wall of the first extending portion 25. The connecting portion 210 has a second through hole 211 for the pulling belt 5 to pass through.

[0057] When unlocking, press the first pressing portion 24 to make its upper clamping point 21 move downward away from the locking position 71 of the docking connector 7. During the downward movement of the first pressing portion 24, the first extending portion 25 moves downward. After the first extending portion 25 moves downward and abuts against the connecting portion 210, when the first extending portion 25 continues to move downward, it pushes the connecting portion 210 to move downward, causing the second pressing portion 27 to move downward, driving its upper clamping point 21 to move downward away from the locking position 71 of the docking connector 7, and then the electrical connector can be pulled out. By arranging the connecting portion 210 below the top wall of the first extending portion 25, the deformation actions of the first pressing portion 24 and the second pressing portion 27 are separated. Only when the first pressing portion 24 moves downward until the top wall of the first extending portion 25 abuts against the connecting portion 210, the continuous downward movement of the first pressing portion 24 will cause the second pressing portion 27 to deform. In this way, only by pressing the first pressing portion 24 can the unlocking operations of the first pressing portion 24 and the second pressing portion 27 be realized, without the need to press in two steps.

[0058] Among them, it further includes a circuit board 3, a cable 4, and a pulling belt 5. The circuit board 3 is arranged inside the insulating housing 1. The cable 4 is electrically connected to the circuit board 3 and passes out of the insulating housing 1. One end of the pulling belt 5 passes through the insulating housing 1, the first through hole 26, and the second through hole 211, and is connected to the other end of the pulling belt 5. Using the pulling belt 5 for unlocking is more convenient.

[0059] Among them, the insulating housing 1 includes a first housing 11 and a second housing 12 that is snap - connected to the first housing 11. An anti - skew - insertion portion 112 and a docking portion 111 protrude forward from the first housing 11. The anti - skew - insertion portion 112 functions to prevent skew - insertion.

[0060] Among them, the second shell 12 extends backward to form a protrusion 121. The protrusion 121 has a third perforation 122. The first perforation 26 is located obliquely above the third perforation 122. One end of the pulling belt 5 passes through the third perforation 122, the first perforation 26, and the second perforation 211, and then is folded back through the third perforation 122 and connected to the other end of the pulling belt 5. Through the settings of the first perforation 26 and the third perforation 122, when the pulling belt 5 is pulled backward, the pulling force is divided into a downward pulling force and a backward pulling force. Only by pulling the pulling belt 5 backward can the unlocking of the locking member 2 and the disconnection of the electrical connector from the docking connector 7 be achieved, without the need for two steps, which is more efficient.

[0061] Embodiment 4:

[0062] As Figure 10 shown, the difference between this embodiment and Embodiment 3 is that:

[0063] The connecting portion 210 is detachably connected to the second extension portion 29. A channel 6 for the pulling belt 5 to pass through is formed between the connecting portion 210 and the first perforation 26. One end of the pulling belt 5 passes through the insulating housing 1, the first perforation 26, and the channel 6, and is connected to the other end of the pulling belt 5. Specifically, one end of the pulling belt 5 passes through the third perforation 122, the first perforation 26, and the channel 6, and is folded back through the third perforation 122 and connected to the other end of the pulling belt 5.

[0064] Embodiment 5:

[0065] As Figure 11 shown, this embodiment provides a connector assembly, including the electrical connector of Embodiment 3 and a docking connector 7 electrically connected to the electrical connector. The docking connector 7 has a locking position 71 that cooperates with the locking member 2. Specifically, there are two groups of locking positions 71, with two in each group. One group cooperates with the clamping point 21 on the first pressing portion 24, and the other group cooperates with the clamping point 21 on the second pressing portion 27.

[0066] Embodiment 6:

[0067] As Figure 12 shown, the difference between this embodiment and Embodiment 5 is that:

[0068] There is one group of locking positions 71, with two in each group. The two locking positions 71 cooperate with the clamping point 21 on the first pressing portion 24.

[0069] Embodiment 7:

[0070] As Figure 13 shown, the difference between this embodiment and Embodiment 3 is that:

[0071] The locking and fastening member 2 further includes a first fixing portion 22, a second fixing portion 212, a first connecting arm 23, and a second connecting arm 28.
