[0047] Figure 1 The figure is a three-dimensional schematic diagram of a connector component with a circuit board placed thereon according to an embodiment of the utility model. Figure 2 for Figure 1 Another three-dimensional schematic diagram of the connector components. Figure 1 and 2 As shown, one aspect of an embodiment of the utility model relates to a connector component 10, which includes:

[0048] The housing 12 has a mounting portion 16 disposed inwardly along a portion of its side wall 14 for placing a circuit board 18, the side wall portion constituting one side of the mounting portion 16, and a switch 20 disposed on the circuit board 18, the switch 20 protruding from the board surface of the circuit board 18 and pointing from the inside of the housing 12 to the outside of the housing 12; and

[0049] The button portion 22 is disposed on the housing 12 and corresponds to the switch 20 on the circuit board 18. Together with the mounting portion 16, a space 24 is provided to receive a pressing switch action.

[0050] The mounting portion 16 is provided with a blocking portion 26 for preventing the switch 20 on the circuit board 18 from being over-pressed.

[0051] This can help prevent the switch 20 disposed on the circuit board 18 of the connector component 10 from being over-pressed, and can help improve the reliability and service life of the switch 20 .

[0052] The connector component 10 may be any component of a charging connection device suitable for an electric vehicle, such as a main body of a charging gun, and may have any possible structure as long as it is suitable for the present invention.

[0053] The housing 12 may have an interior cavity and a sidewall 14 defining the interior cavity. The housing 12 may be generally cylindrical.

[0054] The mounting portion 16 is located in the inner cavity of the housing 12 and is used to stably mount the circuit board 18. The mounting portion 16 may have any possible structure as long as it is suitable for the present invention. The mounting portion 16 is arranged inward along a portion of the side wall 14 of the housing 12, so the mounting portion 16 and the housing 12 may share a portion of the side wall 14.

[0055] The circuit board 18 may be a generally plate-like member having any suitable configuration.

[0056] “The board surface of the circuit board 18 ” means the surface of the circuit board 18 .

[0057] The switch 20 may be a push-button switch and may have any possible structure as long as it is suitable for the present invention.

[0058] Unless otherwise specified, in the present application, “inner” refers to a side close to the central axis of an object, and “outer” refers to a side far from the central axis of an object.

[0059] The button portion 22 may be a portion of the housing 12 that is suitable for being pressed inward and / or downward to press the switch 20 on the circuit board 18 , and may have any suitable configuration. The button portion 22 may correspond to the position of the switch 20 , for example, may be located above the switch 20 .

[0060] The space 24 for receiving the push switch action may be a space inside the mounting portion 16 that allows the button portion 22 to be pressed toward the inside of the housing 12 .

[0061] The blocking portion 26 is used to prevent the button portion 22 from continuing to move toward the inside of the housing 12, so as to prevent the switch 20 on the circuit board 18 from being over-pressed. Specifically, when the button portion 22 is pressed, the button portion 22 can move toward the inside of the housing 12, and when it moves to contact the switch 20 on the circuit board 18, it can drive the switch 20 to continue to move toward the inside of the housing 12, until it contacts the blocking portion 26 and the movement is stopped by the blocking portion. When the aforementioned movement of the button portion 22 is stopped by the blocking portion 26, the switch 20 on the circuit board 18 is no longer pressed by the button portion 22 and continues to move toward the inside of the housing 12, so that the switch 20 can be prevented from being over-pressed, thereby improving the reliability and service life of the switch 20.

[0062] Figure 3 for Figure 1 A schematic diagram of the side view of the connector components. Figure 1 and 3 In some embodiments, the mounting portion 16 includes a latch 28 for inserting the circuit board 18;

[0063] The blocking portion 26 is disposed between the blocking position 28 and the button portion 22 , and the distance between the blocking portion 26 and the button portion 22 is not greater than the maximum moving distance of the switch 20 .

[0064] In this way, it is possible to easily prevent the switch 20 on the circuit board 18 from being over-pressed.

[0065] The clamping position 28 can be a generally groove-shaped structure and can have any suitable structure. When the circuit board 18 is inserted into the clamping position 28, it can be firmly clamped in the clamping position 28 without filling glue into the mounting portion 16 for fixing.

[0066] In addition, omitting the glue potting process can also shorten the installation time of the circuit board 18 and simplify the installation process of the circuit board 18 .

[0067] The blocking portion 26 is disposed between the locking position 28 and the button portion 22 . When the button portion 22 is pressed, it presses the switch 20 on the circuit board 18 inserted in the locking position 28 to move toward the inside of the housing 12 until the button portion 22 is blocked by the blocking portion 26 and cannot move further. At this time, the switch 20 is no longer pressed by the button portion 22 .

[0068] After the circuit board 18 is inserted into the locking position 28 , the top end of the switch 20 on the circuit board 18 may contact the bottom end of the button portion 22 or be spaced a certain distance apart.

[0069] After the circuit board 18 is inserted into the locking position 28, when the top end of the switch 20 on the circuit board 18 contacts the bottom end of the button portion 22, the switch 20 can be pressed by pressing the button portion 22. In this way, the distance the button portion 22 moves when pressed is equal to the distance the switch 20 moves when pressed by the button portion 22.

[0070] After the circuit board 18 is inserted into the locking position 28, with the top of the switch 20 on the circuit board 18 and the bottom of the button portion 22 spaced a certain distance apart, the button portion 22 is pressed until the button portion 22 moves over the distance between the top of the switch 20 and the switch 20 can be pressed. In this way, the distance that the button portion 22 is pressed and moved is greater than the distance that the switch 20 is pressed and moved by the button portion 22.

[0071] In summary, it can be seen that the distance that the button portion 22 moves when pressed is greater than or equal to the distance that the switch 20 moves when pressed by the button portion 22 .

[0072] In this way, the distance between the blocking portion 26 and the button portion 22 is not greater than the maximum moving distance of the switch 20, so that when the button portion 22 moves toward the inside of the housing 12 until it is blocked by the blocking portion 26 and stops moving, the distance that the button portion 22 moves when pressed is not greater than the maximum moving distance of the switch 20. Accordingly, the distance that the switch 20 moves when pressed by the button portion 22 must not be greater than the maximum moving distance of the switch 20. Thus, over-pressing of the switch 20 on the circuit board 18 can be avoided, and the reliability and service life of the switch 20 can be prevented from being reduced due to over-pressing.

[0073] In some embodiments, the blocking portion 26 is in the shape of a U-shaped plate, and the middle opening of the U-shaped plate allows the switch 20 to protrude through.

[0074] Figure 4 To place Figure 1 A three-dimensional schematic diagram of a circuit board of the mounting portion of the connector component. Figure 4 As shown, the switch 20 may include a fixed portion 19 and a movable portion 21 connected to each other, the fixed portion 19 is located on the board surface of the circuit board 18, and the movable portion 21 is located on the fixed portion 19. When the switch 20 is pressed by the button portion 22, the movable portion 21 may move toward the fixed portion 19 and / or the inside of the housing 12.

[0075] Reference Figure 1 and 4 The middle opening portion of the blocking portion 26 allows the switch 20 to protrude toward the outside of the housing 12 and extend into the space 24 between the blocking portion 26 and the button portion 22 for receiving a switch pressing action.

[0076] During the process of inserting the circuit board 18 into the latch 28 , the fixed portion 19 of the switch 20 can move in the middle opening of the blocking portion 26 along the elongation direction of the shell 12 , while the movable portion 21 of the switch 20 moves in the space 24 between the blocking portion 26 and the button portion 22 along the elongation direction of the shell 12 .

[0077] Reference Figure 3 and 4 In some embodiments, a first flange 30 is formed in the latching position 28 , and a recess 32 is formed at a corresponding end of the circuit board 18 , and the first flange 30 and the recess 32 match each other.

[0078] This can help prevent the circuit board 18 from being inserted incorrectly.

[0079] The first flange 30 may be a rectangular parallelepiped protrusion disposed at the end of the locking position 28 , or may be a rectangular parallelepiped end of the locking position 28 . The recess 32 may be a rectangular parallelepiped notch matched with the first flange 30 .

[0080] The first flange 30 of the stopper 28 may correspond to the shape, position and size of the recess 32 of the circuit board 18. When the circuit board 18 is inserted into the stopper 28, if the insertion is correct, the recess 32 of the circuit board 18 may cooperate with the first flange 30 of the stopper 28, and the circuit board 18 may be smoothly and completely inserted into the stopper 28; if the insertion is incorrect, for example, the circuit board 18 is reversely inserted, the first flange 30 of the stopper 28 may prevent the circuit board 18 from being completely inserted into the stopper 28, and a part of the circuit board 18 will be exposed outside the stopper 28 and cannot be further inserted into the stopper 28.

[0081] In addition, the first flange 30 of the locking position 28 can be used to position the circuit board 18. When inserting the circuit board 18, the insertion direction of the circuit board 18 can be predetermined according to the position of the recess 32 of the circuit board 18 and the first flange 30 of the locking position 28, and then the circuit board 18 can be inserted into the locking position 28, so that the circuit board 18 can be correctly inserted smoothly and conveniently.

[0082] Reference Figure 1 In some embodiments, the portion of the housing 12 constituting the mounting portion 16 is formed with a chamfered portion 34 to facilitate insertion of the circuit board 18 into the latching position 28 .

[0083] The chamfered portion 34 can enlarge the end opening of the mounting portion 16. When the circuit board 18 is inserted, the switch 20 on the circuit board 18 will inevitably touch the end opening of the mounting portion 16. The presence of the chamfered portion 34 in the portion of the housing 12 constituting the mounting portion 16 can help increase the probability of the switch 20 entering the mounting portion 16 when it touches the end opening of the mounting portion 16 and / or the chamfered portion 34. At the same time, the inclined surface of the chamfered portion 34 itself can help the switch 20 to easily slide into the mounting portion 16 when it touches the end opening of the mounting portion 16 and / or the chamfered portion 34. In this way, the portion of the housing 12 constituting the mounting portion 16 is formed with the chamfered portion 34, which can help facilitate the insertion of the circuit board 18 into the latching position 28.

[0084] The mounting portion 16 may be located at one end of the housing 12. The circuit board 18 may be inserted into the latching position 28 of the mounting portion 16 by extending from the end of the housing 12.

[0085] Reference Figure 2 In some embodiments, the button portion 22 includes a window 36 formed on the housing 12 and a key 38 disposed in the window 36 for receiving an action of pressing the switch 20 .

[0086] The window 36 may be an opening on the housing 12 corresponding to the position of the switch 20 on the circuit board 18 and may have any suitable configuration.

[0087] The key 38 may be assembled from components such as a spring (not shown), a key cap (not shown) and the like.

[0088] The button 38 receives the action of pressing the switch 20, that is, when the button 38 is pressed, the button 38 moves toward the switch 20 relative to the window 36, thereby pressing the switch 20. When the button 38 is released and / or the movement of the button 38 is blocked by the blocking portion 26, the switch 20 is not pressed by the button 38.

[0089] Figure 5 It is an exploded schematic diagram of a connector according to an embodiment of the utility model. Figure 6 for Figure 5 A simplified front view of the connector in the assembled state. Figure 7 for Figure 6 A cross-sectional view of the connector. Figure 5-7 As shown, another aspect of the embodiment of the utility model relates to a connector 40, which includes:

[0090] Housing 12 (see Figure 1 ), a mounting portion 16 is provided inwardly along a portion of the side wall 14 thereof, and the side wall 14 portion constitutes one side of the mounting portion 16;

[0091] A circuit board 18 is disposed in the mounting portion 16 in the housing 12. A switch 20 is disposed on the circuit board 18. The switch 20 protrudes from the surface of the circuit board 18 and points from the inside of the housing 12 to the outside of the housing 12; and

[0092] The button portion 22 is disposed on the housing 12 and corresponds to the switch 20 on the circuit board 18. Together with the mounting portion 16, a space 24 is provided to receive the action of pressing the switch 20.

[0093] The mounting portion 16 is provided with a blocking portion 26 for preventing the switch 20 on the circuit board 18 from being over-pressed.

[0094] This can help prevent the switch 20 on the circuit board 18 in the housing 12 of the connector 40 from being over-pressed, and can help improve the reliability and service life of the switch 20 and even the connector 40 .

[0095] The connector 40 may be any charging connection device suitable for an electric vehicle, such as a charging gun, and may have any possible structure as long as it is suitable for the present invention.

[0096] Reference Figure 1 and 7 The housing 12 may have an interior cavity and a side wall 14 defining the interior cavity. The housing 12 may be a substantially cylindrical body.

[0097] The mounting portion 16 is located in the inner cavity of the housing 12 and is used to stably mount the circuit board 18. The mounting portion 16 may have any possible structure as long as it is suitable for the present invention. The mounting portion 16 is arranged inward along a portion of the side wall 14 of the housing 12, so the mounting portion 16 and the housing 12 may share a portion of the side wall 14.

[0098] The circuit board 18 may be a generally plate-like member having any suitable configuration.

[0099] The switch 20 may be a push-button switch and may have any possible structure as long as it is suitable for the present invention.

[0100] The button portion 22 may be a portion of the housing 12 that is suitable for being pressed inward and / or downward to press the switch 20 on the circuit board 18 , and may have any suitable configuration. The button portion 22 may correspond to the position of the switch 20 , for example, may be located above the switch 20 .

[0101] The space 24 for receiving the push switch action may be a space inside the mounting portion 16 that allows the button portion 22 to be pressed toward the inside of the housing 12 .

[0102] The blocking portion 26 is used to prevent the button portion 22 from continuing to move toward the inside of the housing 12, so as to prevent the switch 20 on the circuit board 18 from being over-pressed. Specifically, when the button portion 22 is pressed, the button portion 22 can move toward the inside of the housing 12, and when it moves to contact the switch 20 on the circuit board 18, it can drive the switch 20 to continue to move toward the inside of the housing 12, until it contacts the blocking portion 26 and the movement is blocked by the blocking portion. When the aforementioned movement of the button portion 22 is blocked by the blocking portion 26, the switch 20 on the circuit board 18 is no longer pressed by the button portion 22 and continues to move toward the inside of the housing 12, so that the switch 20 can be prevented from being over-pressed, thereby improving the reliability and service life of the switch 20 and even the connector 40.

[0103] Figure 8 for Figure 5 A simplified cross-sectional view of the connector. Figure 3 , 7 and 8. In some embodiments, the mounting portion 16 includes a latch 28 for inserting the circuit board 18;

[0104] The blocking portion 26 is disposed between the blocking position 28 and the button portion 22 , and the distance between the blocking portion 26 and the button portion 22 is not greater than the maximum moving distance of the switch 20 .

[0105] In this way, it is possible to easily prevent the switch 20 on the circuit board 18 from being over-pressed.

[0106] The clamping position 28 can be a generally groove-shaped structure and can have any suitable structure. When the circuit board 18 is inserted into the clamping position 28, it can be firmly clamped in the clamping position 28 without filling glue into the mounting portion 16 for fixing.

[0107] In addition, omitting the glue potting process can also shorten the installation time of the circuit board 18 and simplify the installation process of the circuit board 18 .

[0108] In addition, the glue used for glue pouring is usually expensive, and after pouring the glue, the product to be cured needs to be placed in a suitable position and wait for a long time for the glue to cure. Therefore, omitting the glue pouring can also reduce the manufacturing cost of the connector 40, shorten the manufacturing time of the connector 40, and simplify the manufacturing process of the connector 40.

[0109] Furthermore, omitting the glue potting process can also reduce the weight of the connector 40 .

[0110] The blocking portion 26 is disposed between the locking position 28 and the button portion 22 . When the button portion 22 is pressed, it presses the switch 20 on the circuit board 18 inserted in the locking position 28 to move toward the inside of the housing 12 until the button portion 22 is blocked by the blocking portion 26 and cannot move further. At this time, the switch 20 is no longer pressed by the button portion 22 .

[0111] After the circuit board 18 is inserted into the locking position 28 , the top end of the switch 20 on the circuit board 18 may contact the bottom end of the button portion 22 or be spaced a certain distance apart.

[0112] After the circuit board 18 is inserted into the locking position 28, when the top end of the switch 20 on the circuit board 18 contacts the bottom end of the button portion 22, the switch 20 can be pressed by pressing the button portion 22. In this way, the distance the button portion 22 moves when pressed is equal to the distance the switch 20 moves when pressed by the button portion 22.

[0113] After the circuit board 18 is inserted into the locking position 28, with the top of the switch 20 on the circuit board 18 and the bottom of the button portion 22 spaced a certain distance apart, the button portion 22 is pressed until the button portion 22 moves over the distance between the top of the switch 20 and the switch 20 can be pressed. In this way, the distance that the button portion 22 is pressed and moved is greater than the distance that the switch 20 is pressed and moved by the button portion 22.

[0114] In summary, it can be seen that the distance that the button portion 22 moves when pressed is greater than or equal to the distance that the switch 20 moves when pressed by the button portion 22 .

[0115] In this way, the distance between the blocking portion 26 and the button portion 22 is not greater than the maximum moving distance of the switch 20, so that when the button portion 22 moves toward the inside of the housing 12 until it is blocked by the blocking portion 26 and stops moving, the distance that the button portion 22 moves when pressed is not greater than the maximum moving distance of the switch 20. Accordingly, the distance that the switch 20 moves when pressed by the button portion 22 must not be greater than the maximum moving distance of the switch 20. Thus, over-pressing of the switch 20 on the circuit board 18 can be avoided, and the reliability and service life of the switch 20 and even the connector 40 can be prevented from being reduced due to over-pressing.

[0116] In some embodiments, the blocking portion 26 is in the shape of a U-shaped plate, and the middle opening of the U-shaped plate allows the switch 20 to protrude through.

[0117] Reference Figure 4 The switch 20 may include a fixed portion 19 and a movable portion 21 connected to each other, wherein the fixed portion 19 is located on the board surface of the circuit board 18, and the movable portion 21 is located on the fixed portion 19. When the switch 20 is pressed by the button portion 22, the movable portion 21 may move toward the fixed portion 19 and / or the inside of the housing 12.

[0118] Reference Figure 1 , 4 7, the middle opening portion of the blocking portion 26 allows the switch 20 to protrude toward the outside of the housing 12 and extend into the space 24 between the blocking portion 26 and the button portion 22 for receiving a push switch action.

[0119] During the process of inserting the circuit board 18 into the latch 28 , the fixed portion 19 of the switch 20 can move in the middle opening of the blocking portion 26 along the elongation direction of the shell 12 , while the movable portion 21 of the switch 20 moves in the space 24 between the blocking portion 26 and the button portion 22 along the elongation direction of the shell 12 .

[0120] Reference Figure 3 , 4 In some embodiments, the first flange 30 is formed in the latching position 28 , and a concave portion 32 is formed at the corresponding end of the circuit board 18 , and the first flange 30 and the concave portion 32 match each other.

[0121] This can help prevent the circuit board 18 from being inserted incorrectly.

[0122] The first flange 30 may be a rectangular parallelepiped protrusion disposed at the end of the locking position 28 , or may be a rectangular parallelepiped end of the locking position 28 . The recess 32 may be a rectangular parallelepiped notch matched with the first flange 30 .

[0123] The first flange 30 of the stopper 28 may correspond to the shape, position and size of the recess 32 of the circuit board 18. When the circuit board 18 is inserted into the stopper 28, if the insertion is correct, the recess 32 of the circuit board 18 may cooperate with the first flange 30 of the stopper 28, and the circuit board 18 may be smoothly and completely inserted into the stopper 28; if the insertion is incorrect, for example, the circuit board 18 is reversely inserted, the first flange 30 of the stopper 28 may prevent the circuit board 18 from being completely inserted into the stopper 28, and a part of the circuit board 18 will be exposed outside the stopper 28 and cannot be further inserted into the stopper 28.

[0124] In addition, the first flange 30 of the locking position 28 can be used to position the circuit board 18. When inserting the circuit board 18, the insertion direction of the circuit board 18 can be predetermined according to the position of the recess 32 of the circuit board 18 and the first flange 30 of the locking position 28, and then the circuit board 18 can be inserted into the locking position 28, so that the circuit board 18 can be correctly inserted smoothly and conveniently.

[0125] Reference Figure 1 and 8 In some embodiments, the portion of the housing 12 constituting the mounting portion 16 is formed with a chamfered portion 34 to facilitate insertion of the circuit board 18 into the latching position 28 .

[0126] The chamfered portion 34 can enlarge the end opening of the mounting portion 16. When the circuit board 18 is inserted, the switch 20 on the circuit board 18 will inevitably touch the end opening of the mounting portion 16. The presence of the chamfered portion 34 in the portion of the housing 12 constituting the mounting portion 16 can help increase the probability of the switch 20 entering the mounting portion 16 when it touches the end opening of the mounting portion 16 and / or the chamfered portion 34. At the same time, the inclined surface of the chamfered portion 34 itself can help the switch 20 to easily slide into the mounting portion 16 when it touches the end opening of the mounting portion 16 and / or the chamfered portion 34. In this way, the portion of the housing 12 constituting the mounting portion 16 is formed with the chamfered portion 34, which can help facilitate the insertion of the circuit board 18 into the latching position 28.

[0127] The mounting portion 16 may be located at one end of the housing 12. The circuit board 18 may be inserted into the latching position 28 of the mounting portion 16 by extending from the end of the housing 12.

[0129] The window 36 may be an opening on the housing 12 corresponding to the position of the switch 20 on the circuit board 18 and may have any suitable configuration.

[0130] The key 38 may be assembled from components such as a spring (not shown), a key cap (not shown) and the like.

[0131] The button 38 receives the action of pressing the switch 20, that is, when the button 38 is pressed, the button 38 moves toward the switch 20 relative to the window 36, thereby pressing the switch 20. When the button 38 is released and / or the movement of the button 38 is blocked by the blocking portion 26, the switch 20 is not pressed by the button 38.

[0132] Reference Figure 5 In some embodiments, the connector 40 may further include a cover 53 for waterproofing, which may also contribute to the aesthetic appearance of the housing 12 of the connector 40 .

The plug 39 may include a bracket 41 and a terminal 43 mounted on the bracket 41. The bracket 41 may be fixed to the plug 39 by a first fastener 45, such as a screw.

[0142] The end of the plug 39 may include a buckle 37, and the end of the housing 12 connected to the plug 39 may include a groove 13, and the buckle 37 and the groove 13 match each other. The end of the plug 39 provided with the buckle 37 can extend into the end of the housing 12 provided with the groove 13, so that the plug 39 and the housing 12 are connected by the buckle 37 and the groove 13 matching each other.

[0143] The end of the plug 39 connected to the housing 12 may include a first hole 15, and the end of the housing 12 connected to the plug 39 may include a second hole 17, so that a second fastener 47, such as a screw, can be passed through the first hole 15 and the second hole 17 to firmly mount the plug 39 to the housing 12.

[0144] The cover 53 can cover the second fastener 47 and the second hole 17 to prevent water from entering the interior of the connector 40 along the edges of the second fastener 47 and the second hole 17 , and at the same time, it can contribute to the aesthetic appearance of the housing 12 of the connector 40 .

[0145] The connector 40 may further include an O-ring 49 for filling the gap between the plug 39 and the housing 12 to prevent water and dust, etc. The O-ring 49 may be sleeved on the end of the plug 39 connected to the housing 12, and enter the end of the housing 12 connected to the plug 39 together with the end of the plug 39.

[0146] The cable 42 can enter the housing 12 from one end of the housing 12, for example, the end away from the plug 39, and connect to the terminal 43 of the plug 39. The terminal 43 and the circuit board 18 inserted into the mounting portion 16 are connected to each other for signal.

[0147] The sheath 44 may be a generally hollow cylindrical body and may have any suitable configuration. The sheath 44 may be threadedly connected to an end of the housing 12 away from the plug 39 .

[0148] Reference Figure 5 In some embodiments, a hollow structure 46 is provided on the sheath 44 to increase the degree of deformation of the sheath 44 .

[0149] The hollow structure 46 may be an array of open holes and may have any suitable configuration. The portion of the sheath 44 with the hollow structure 46 may be made of TPE to ensure that the hollow structure 46 is resistant to large deformation. The sheath 44 may also include a portion connected to the portion with the hollow structure 46, which may be made of nylon and have external threads for threaded connection with the housing 12.

[0150] Reference Figure 5 and 7 In some embodiments, the connector 40 further includes a sealing ring 48 for waterproofing, and the sealing ring 48 is sandwiched between the sheath 44 and the housing 12 .

[0151] The sealing ring 48 may be an annular body with a plurality of grooves on the outer surface, and may be used to prevent water from entering the housing 12 along the cable 42. The sealing ring 48 may cooperate with the housing 12, and may be pressed by the sheath 44 against one end of the housing 12 near the sheath 44.

[0152] In some embodiments, the connector 40 further includes a wire clamp 50 for fixing the cable 42 . The wire clamp 50 is sleeved on the cable 42 and clamped between the sheath 44 and the sealing ring 48 .

[0153] The wire clamp 50 may have any possible structure as long as it is suitable for the present invention. The wire clamp 50 may be disposed inside the housing 12 near one end of the sheath 44. The wire clamp 50 may prevent the cable 42 from moving due to external pulling, for example.

[0154] Reference Figure 5 , 7 and 8. In some embodiments, the wire clip 50 comprises:

[0155] a cylinder 52 enclosing the cable 42; and

[0156] The second flange 54 protrudes outward from one end of the cylinder 52.

[0157] The cylinder 52 is located between the cable 42 and the sheath 44 , and the second flange 54 is sandwiched between the sheath 44 and the sealing ring 48 along the extension direction of the connector 40 .

[0158] In this way, the wire clamp 50 can help prevent the cable 42 from moving along the extension direction of the connector 40 .

[0159] The cylinder 52 and the second flange 54 can each have any possible structure as long as they are suitable for the present invention. For example, the cylinder 52 can be substantially cylindrical. The second flange 54 can be substantially a thin sheet annular body.

[0160] The cable 42 may pass through the sheath 44, the wire clamp 50 and the sealing ring 48 in sequence and then enter the housing 12. The wire clamp 50 may be made of metal. After the position of the cable 42 is determined, the barrel 52 of the wire clamp 50 may be squeezed or pressed until it is deformed, so that the deformed barrel 52 clamps the cable 42.

[0161] The sheath 44 and the housing 12 are firmly threadedly connected to each other, and the second flange 54 of the wire clamp 50 is clamped between the sheath 44 and the sealing ring 48 along the extension direction of the connector 40. When the cable 42 is pulled, the second flange 54 is prevented from moving in the direction close to the plug 39 along the extension direction of the connector 40 by the sealing ring 48 abutting against the housing 12, and the second flange 54 is prevented from moving in the direction away from the plug 39 along the extension direction of the connector 40 by the sheath 44. In this way, the wire clamp 50 will not move in the extension direction of the connector 40 due to the pulling of the cable 42, and at the same time, the cable 42 clamped by the deformed cylinder 52 of the wire clamp 50 will not move in the extension direction of the connector 40.

[0162] Reference Figure 5 In some embodiments, the connector 40 may further include a dust cover 56 for preventing dust, water, oil, etc. from entering the end of the plug 39 away from the housing 12 .
