[0046] FIG1 is a perspective schematic diagram of a connector component with a circuit board placed thereon according to an embodiment of the present application. FIG2 is another perspective schematic diagram of the connector component in FIG1 . As shown in FIG1 and FIG2 , one aspect of an embodiment of the present application relates to a connector component 10, which includes:

[0047] The housing 12 has a mounting portion 16 disposed inwardly along a portion of its side wall 14 for accommodating a circuit board 18. The side wall portion constitutes one side of the mounting portion 16. The circuit board 18 is provided with a switch 20. The switch 20 protrudes from the surface of the circuit board 18 and points from the interior of the housing 12 to the exterior of the housing 12.

[0048] The button portion 22 is provided on the housing 12 and corresponds to the switch 20 on the circuit board 18. Together with the mounting portion 16, it provides a space 24 for receiving a press switch action.

[0049] 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.

[0050] This can help prevent the switch 20 provided 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 .

[0051] 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 application.

[0052] The housing 12 may have an interior cavity and a sidewall 14 defining the interior cavity. The housing 12 may be generally cylindrical.

[0053] Mounting portion 16 is positioned within the interior cavity of housing 12 and is configured to securely mount circuit board 18. Mounting portion 16 may have any configuration suitable for the present application. Mounting portion 16 is disposed inwardly along a portion of sidewall 14 of housing 12, and thus, mounting portion 16 and housing 12 may share a portion of sidewall 14.

[0054] The circuit board 18 may be a generally plate-shaped member having any suitable configuration.

[0055] “The surface of the circuit board 18 ” refers to the surface of the circuit board 18 .

[0056] The switch 20 may be a push-button switch and may have any possible configuration as long as it is suitable for the present application.

[0057] 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 away from the central axis of an object.

[0058] The button portion 22 may be a portion of the housing 12 adapted to be pressed inward and / or downward to actuate 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.

[0059] 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 into the housing 12 .

[0060] The blocking portion 26 is used to prevent the button portion 22 from further moving toward the interior of the housing 12, thereby preventing overpressing of the switch 20 on the circuit board 18. Specifically, when the button portion 22 is pressed, it can move toward the interior of the housing 12. When it contacts the switch 20 on the circuit board 18, it can drive the switch 20 to continue moving toward the interior of the housing 12 until it contacts the blocking portion 26 and is stopped. When the 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 can continue to move toward the interior of the housing 12. This prevents overpressing the switch 20, thereby improving the reliability and service life of the switch 20.

[0061] Figure 3 is a schematic side view of the connector component in Figure 1. Referring to Figures 1 and 3, in some embodiments, the mounting portion 16 includes a latch 28 for inserting the circuit board 18;

[0062] The blocking portion 26 is disposed between the latching position 28 and the button portion 22 , and the distance between the blocking portion 26 and the button portion 22 is no greater than the maximum moving distance of the switch 20 .

[0063] In this way, it is possible to simply prevent the switch 20 on the circuit board 18 from being over-pressed.

[0064] The latch 28 can be a generally slot-shaped structure and can have any suitable configuration. When the circuit board 18 is inserted into the latch 28, it can be firmly locked in the latch 28 without the need to fill glue into the mounting portion 16 to fix it.

[0065] 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.

[0066] The blocking portion 26 is provided between the latching 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 latching 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.

[0067] After the circuit board 18 is inserted into the latch 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.

[0068] After the circuit board 18 is inserted into the latch 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 .

[0069] After the circuit board 18 is inserted into the latch 28 , with the top of the switch 20 on the circuit board 18 spaced a certain distance from the bottom of the button portion 22 , the button portion 22 is pressed until the button portion 22 moves over the distance from the top of the switch 20 . In this way, the distance the button portion 22 moves when pressed is greater than the distance the switch 20 moves when pressed by the button portion 22 .

[0070] In summary, it can be seen that the distance the button portion 22 moves when pressed is greater than or equal to the distance the switch 20 moves when pressed by the button portion 22 .

[0071] In this way, the distance between the blocking portion 26 and the button portion 22 is no greater than the maximum movement distance of the switch 20. This ensures that when the button portion 22 moves toward the interior of the housing 12 and stops being blocked by the blocking portion 26, the distance the button portion 22 moves when pressed is no greater than the maximum movement distance of the switch 20. Accordingly, the distance the switch 20 moves when pressed by the button portion 22 is no greater than the maximum movement distance of the switch 20. This prevents overpressing the switch 20 on the circuit board 18 and prevents the reliability and service life of the switch 20 from being reduced due to overpressing.

[0072] 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.

[0073] Figure 4 is a perspective view of a circuit board placed within the mounting portion of the connector assembly shown in Figure 1. As shown in Figure 4 , switch 20 may include a fixed portion 19 and a movable portion 21 connected to each other. Fixed portion 19 is located on a surface of circuit board 18, and movable portion 21 is located on fixed portion 19. When switch 20 is pressed by button portion 22, movable portion 21 moves toward fixed portion 19 and / or the interior of housing 12.

[0074] 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.

[0075] 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 extension direction of the shell 12, and at the same time, 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 extension direction of the shell 12.

[0076] 3 and 4 , in some embodiments, a first flange 30 is defined within the latching portion 28 , and a recess 32 is formed at a corresponding end of the circuit board 18 , where the first flange 30 and the recess 32 match each other.

[0077] This can help prevent the circuit board 18 from being inserted incorrectly.

[0078] The first flange 30 may be a rectangular parallelepiped protrusion provided at the end of the latching portion 28 , or may be the rectangular parallelepiped end of the latching portion 28 . The recess 32 may be a rectangular parallelepiped notch matching the first flange 30 .

[0079] The first flange 30 of the retaining member 28 can 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 retaining member 28, if the insertion is correct, the recess 32 of the circuit board 18 will mate with the first flange 30 of the retaining member 28, and the circuit board 18 can be smoothly and completely inserted into the retaining member 28. However, if the insertion is incorrect, such as if the circuit board 18 is inserted upside down, the first flange 30 of the retaining member 28 may prevent the circuit board 18 from being fully inserted into the retaining member 28, and a portion of the circuit board 18 will be exposed outside the retaining member 28, making it impossible to further insert the circuit board 18 into the retaining member 28.

[0080] Furthermore, the first flange 30 of the retaining member 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 based on the position of the recess 32 of the circuit board 18 and the first flange 30 of the retaining member 28. Then, the circuit board 18 can be inserted into the retaining member 28, thereby smoothly and conveniently completing the correct insertion of the circuit board 18.

[0081] 1 , in some embodiments, a 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 .

[0082] The chamfered portion 34 enlarges the end opening of the mounting portion 16. When inserting the circuit board 18, the switch 20 on the circuit board 18 inevitably contacts the end opening of the mounting portion 16. The presence of the chamfered portion 34 in the portion of the housing 12 that constitutes the mounting portion 16 increases the probability that the switch 20 will enter the mounting portion 16 upon contact with the end opening of the mounting portion 16 and / or the chamfered portion 34. Furthermore, the inclined surface of the chamfered portion 34 facilitates the easy sliding of the switch 20 into the mounting portion 16 upon contact with the end opening of the mounting portion 16 and / or the chamfered portion 34. Thus, the chamfered portion 34 formed in the portion of the housing 12 that constitutes the mounting portion 16 facilitates the easy insertion of the circuit board 18 into the latch 28.

[0083] 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 .

[0084] 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 .

[0085] The window 36 may be an opening in the housing 12 corresponding to the location of the switch 20 on the circuit board 18 and may have any suitable configuration.

[0086] The button 38 may be assembled from components such as a spring (not shown), a button cap (not shown), and the like.

[0087] The button 38 receives the action of pressing the switch 20, that is, when the button 38 is pressed, the button 38 moves relative to the window 36 toward the switch 20, 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 no longer pressed by the button 38.

[0088] FIG5 is an exploded view of a connector according to an embodiment of the present application. FIG6 is a simplified front view of the connector in FIG5 in an assembled state. FIG7 is a cross-sectional view of the connector in FIG6. As shown in FIG5-7, another aspect of the embodiment of the present application relates to a connector 40, which includes:

[0089] The housing 12 (see FIG1 ) is provided with a mounting portion 16 along a portion of its side wall 14 inwardly, and the side wall 14 partially constitutes one side of the mounting portion 16 ;

[0090] A circuit board 18 is disposed in the mounting portion 16 within 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 interior of the housing 12 to the exterior of the housing 12 .

[0091] The button portion 22 is provided on the housing 12 and corresponds to the switch 20 on the circuit board 18. Together with the mounting portion 16, it provides a space 24 for receiving the action of pressing the switch 20.

[0092] 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.

[0093] This can help prevent over-pressing of the switch 20 on the circuit board 18 within the housing 12 of the connector 40 , thereby helping to improve the reliability and service life of the switch 20 and even the connector 40 .

[0094] 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 application.

[0095] 1 and 7, the housing 12 may have an interior cavity and a sidewall 14 defining the interior cavity. The housing 12 may be generally cylindrical.

[0096] Mounting portion 16 is positioned within the interior cavity of housing 12 and is configured to securely mount circuit board 18. Mounting portion 16 may have any configuration suitable for the present application. Mounting portion 16 is disposed inwardly along a portion of sidewall 14 of housing 12, and thus, mounting portion 16 and housing 12 may share a portion of sidewall 14.

[0097] The circuit board 18 may be a generally plate-shaped member having any suitable configuration.

[0098] The switch 20 may be a push-button switch and may have any possible configuration as long as it is suitable for the present application.

[0099] The button portion 22 may be a portion of the housing 12 adapted to be pressed inward and / or downward to actuate 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.

[0100] 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 into the housing 12 .

[0101] The blocking portion 26 is used to prevent the button portion 22 from further moving toward the interior of the housing 12, thereby preventing overpressing of the switch 20 on the circuit board 18. Specifically, when the button portion 22 is pressed, it can move toward the interior of the housing 12. When it contacts the switch 20 on the circuit board 18, it can drive the switch 20 to continue moving toward the interior of the housing 12 until it contacts the blocking portion 26 and is stopped. When the 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 can continue to move toward the interior of the housing 12. This prevents overpressing the switch 20, thereby improving the reliability and service life of the switch 20 and, consequently, the connector 40.

[0102] Figure 8 is a simplified cross-sectional view of the connector in Figure 5. Referring to Figures 3, 7, and 8, in some embodiments, the mounting portion 16 includes a latch 28 for inserting the circuit board 18;

[0103] The blocking portion 26 is disposed between the latching position 28 and the button portion 22 , and the distance between the blocking portion 26 and the button portion 22 is no greater than the maximum moving distance of the switch 20 .

[0104] In this way, it is possible to simply prevent the switch 20 on the circuit board 18 from being over-pressed.

[0105] The latch 28 can be a generally slot-shaped structure and can have any suitable configuration. When the circuit board 18 is inserted into the latch 28, it can be firmly locked in the latch 28 without the need to fill glue into the mounting portion 16 to fix it.

[0106] 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.

[0107] Furthermore, the glue used for glue potting is usually quite expensive, and after the glue is potted, the product to be cured must be placed in a suitable position and a long time must be allowed for the glue to cure. Therefore, omitting the glue potting step 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.

[0108] Furthermore, omitting the glue potting process can also reduce the weight of the connector 40 .

[0109] The blocking portion 26 is provided 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.

[0110] After the circuit board 18 is inserted into the latch 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.

[0111] After the circuit board 18 is inserted into the latch 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 .

[0112] After the circuit board 18 is inserted into the latch 28 , with the top of the switch 20 on the circuit board 18 spaced a certain distance from the bottom of the button portion 22 , the button portion 22 is pressed until the button portion 22 moves over the distance from the top of the switch 20 . In this way, the distance the button portion 22 moves when pressed is greater than the distance the switch 20 moves when pressed by the button portion 22 .

[0113] In summary, it can be seen that the distance the button portion 22 moves when pressed is greater than or equal to the distance the switch 20 moves when pressed by the button portion 22 .

[0114] In this way, the distance between the blocking portion 26 and the button portion 22 is no greater than the maximum movement distance of the switch 20. This ensures that when the button portion 22 moves toward the interior of the housing 12 until it is blocked by the blocking portion 26 and stops moving, the distance the button portion 22 moves when pressed is no greater than the maximum movement distance of the switch 20. Accordingly, the distance the switch 20 moves when pressed by the button portion 22 is no greater than the maximum movement distance of the switch 20. This prevents overpressing the switch 20 on the circuit board 18 and prevents the reliability and service life of the switch 20 and, consequently, the connector 40 from being reduced due to overpressing.

[0115] 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.

[0116] 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 a 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 interior of the housing 12.

[0117] 1 , 4 and 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 switch pressing action.

[0118] 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 extension direction of the shell 12, and at the same time, 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 extension direction of the shell 12.

[0119] 3 , 4 and 8 , in some embodiments, a first flange 30 is defined within the latching position 28 , and a recess 32 is formed at a corresponding end of the circuit board 18 , wherein the first flange 30 and the recess 32 match each other.

[0120] This can help prevent the circuit board 18 from being inserted incorrectly.

[0121] The first flange 30 may be a rectangular parallelepiped protrusion provided at the end of the latching portion 28 , or may be the rectangular parallelepiped end of the latching portion 28 . The recess 32 may be a rectangular parallelepiped notch matching the first flange 30 .

[0122] The first flange 30 of the retaining member 28 can 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 retaining member 28, if the insertion is correct, the recess 32 of the circuit board 18 will mate with the first flange 30 of the retaining member 28, and the circuit board 18 can be smoothly and completely inserted into the retaining member 28. However, if the insertion is incorrect, such as if the circuit board 18 is inserted upside down, the first flange 30 of the retaining member 28 may prevent the circuit board 18 from being fully inserted into the retaining member 28, and a portion of the circuit board 18 will be exposed outside the retaining member 28, making it impossible to further insert the circuit board 18 into the retaining member 28.

[0123] Furthermore, the first flange 30 of the retaining member 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 based on the position of the recess 32 of the circuit board 18 and the first flange 30 of the retaining member 28.
