Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a female end component, a male end component, a connector and a vehicle. Background Art

[0002] Connectors generally include male and female components, and an axial docking locking structure needs to be designed between the male and female components. A traditional way to connect male and female components is to use a snap-on fit. The snap-on fit structure has poor strength and is easily damaged by frequent plugging and unplugging. Therefore, a ball-type locking structure has emerged. Another way to connect is to use a double-row ball to push the sleeve to produce axial movement and lock. There are two specifications of balls, which are prone to mixing or installation misalignment during assembly. At the same time, during installation, the sleeve will produce axial reciprocating motion, and the sleeve rebound process is easy to hit the hand, affecting the operating experience.

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0051] Connectors generally include male and female components, and an axial docking and locking structure needs to be designed between the male and female components. A traditional way to connect male and female components is to use a snap-on fit. The snap-on fit structure has poor strength and is easily damaged by frequent plugging and unplugging. Another way to connect is to use a double-row ball to push the sleeve to produce axial movement and lock. There are two specifications of balls, which are prone to mixing or installation misalignment during assembly. At the same time, during installation, the sleeve will produce axial reciprocating motion, and the sleeve rebound process is easy to hit the hand, affecting the operating experience.

[0052] In view of this, the present application proposes a connector 100, Figures 1 to 10This is a schematic structural diagram of an embodiment of the connector 100 provided in the present application. The connector 100 provided in the present application has a simple structure and a simple assembly method. The connector 100 will be described in detail below in conjunction with the main drawings.

[0053] According to a third aspect of the present application, a connector 100 is provided. The connector 100 includes a female end component 10 and a male end component 20 . The male end component 20 is plug-fitted with the female end component 10 .

[0054] See also Figure 1 , Figure 1 It is a structural schematic diagram of the separated state of the male end component 20 and the female end component 10 provided in the present application. In the separated state, the male end component 20 is located on the outside of the female end component 10. In the female end component 10, the upper limit boss 21 of the first sleeve 11 abuts against the locking piece 121 on the second sleeve 12.

[0055] See also Figure 2 , Figure 2 It is a schematic diagram of the first process of inserting the male end component 20 into the female end component 10 provided by the present application. Specifically, when the male end component 20 is inserted into the female end component 10, the limiting protrusion 111 on the male end component 20 abuts against the locking member 121, pushing the locking member 121 to move in the direction close to the first elastic member 13. Since the locking member 121 is arranged on the second sleeve 12, the second sleeve 12 is driven to move. At this time, the second sleeve 12 compresses the first elastic member 13, and the first sleeve 11 is stationary. When the second sleeve 12 moves to the point where the through hole on the second sleeve 12 corresponds to the first avoidance portion 112 on the first sleeve 11, the locking member 121 can move between the first avoidance portion 112 and the through hole. At this time, the male end component 20 stops moving. At this time, the second sleeve 12 is in the second position, and the connector 100 is in the first state before the locked state.

[0056] See also Figure 3 , Figure 3 It is a schematic diagram of the locking state of the male end component 20 and the female end component 10 provided by the present application. Specifically, when the locking member 121 enters the first avoidance portion 112, the male end component 20 stops moving, the first elastic member 13 rebounds, and pushes the second sleeve 12 to move away from the first elastic member 13, and the second sleeve 12 drives the locking member 121 to leave the first avoidance portion 112, so that the locking member 121 is reset. When the locking member 121 is reset, the locking member 121 is clamped by the limiting protrusion 111 and the limiting boss 21, and is fixed on the second sleeve 12. At this time, the locking member 121 relatively fixes the second sleeve 12, the limiting protrusion 111 and the limiting boss 21, thereby realizing the locking and fixing of the male end component 20 and the female end component 10, and the connector 100 is in a locked state.

[0057] See also Figure 4 , Figure 4 It is a schematic diagram of the unlocking process of the male end component 20 and the female end component 10 provided by the present application. Specifically, when the male end component 20 and the female end component 10 need to be separated, the first sleeve 11 is moved in the direction close to the male end component 20 until the first avoidance portion 112 on the first sleeve 11 corresponds to the locking member 121, the through hole on the second sleeve 12 corresponds to the first avoidance portion 112, and the locking member 121 moves between the through hole and the first avoidance portion 112. At this time, the connector 100 is in an unlocked state, the second sleeve 12, the limiting protrusion 111 and the limiting boss 21 can be relatively separated, the male end component 20 is pulled out, and the male end component 20 and the female end component 10 are separated.

[0058] It should be noted that during the movement of the first sleeve 11, the first sleeve 11 will compress the first elastic member 13. When the male end element 20 is separated from the female end element 10, the first elastic member 13 will rebound, driving the first sleeve 11 to reset, thereby causing the locking member 121 to leave the first avoidance portion 112.

[0059] According to a first aspect of the present application, a female end component 10 is provided. The female end component 10 is applied to a connector 100. Figures 5 to 8 A schematic structural diagram of an embodiment of the female end component 10 provided in the present application.

[0060] See also Figure 5 The female end element 10 includes a first sleeve 11, a second sleeve 12 and a first elastic member 13. The first sleeve 11 is provided with a limiting protrusion 111; at least part of the second sleeve 12 is located in the first sleeve 11, and the second sleeve 12 can move relative to the first sleeve 11 and has a first position and a second position. The second sleeve 12 includes a body 122 and a locking member 121. The body 122 is provided with a through hole. When the second sleeve 12 is in the first position, the limiting protrusion 111 abuts against the locking member 121, so that the locking member 121 is fixed relative to the body 122, and part of the locking member 121 protrudes from the inner side wall of the second sleeve 12 through the through hole; when the second sleeve 12 is in the second position, the locking member 121 is movable relative to the body 122; the first elastic member 13 is elastically connected between the first sleeve 11 and the second sleeve 12, so that the second sleeve 12 has a tendency to move toward the first position.

[0061] In the technical solution of the present application, the second sleeve 12 is partially located in the first sleeve 11, and the first sleeve 11 and the second sleeve 12 are elastically connected by the first elastic member 13, and the first sleeve 11 and the second sleeve 12 can slide relative to each other along the axial direction of the female end element 10, thereby meeting the locking and unlocking requirements, with a simple structure, high connection reliability, and simple operation. Due to the connection of the first elastic member 13, during the sliding process of the first sleeve 11 and the second sleeve 12, the sliding process of the first sleeve 11 and the second sleeve 12 is more stable, and will not suddenly rebound and hit the hand, and the operation is simpler; at the same time, the locking member 121 is used to cooperate with the displacement, so that the second sleeve 12 can be in the first position and the second position. In the first position, the limiting protrusion 111 abuts the locking member 121, so that the locking member 121 is fixed relative to the body 122, and part of the locking member 121 protrudes from the inner side wall of the second sleeve 12 by the through hole. In the second position, the locking member 121 can move relative to the body 122, making the installation and disassembly process simpler and faster.

[0062] In some embodiments, see Figure 5 and Figure 6 The first sleeve 11 is provided with an opening, and the first sleeve 11 is provided with a first avoidance portion 112, and the first avoidance portion 112 is located on the side of the limiting protrusion 111 away from the opening; when the second sleeve 12 is in the second position, the through hole and the first avoidance portion 112 are arranged opposite to each other, so that the locking member 121 is movable relative to the body 122.

[0063] Specifically, the first avoidance portion 112 is used to correspond to the through hole so that the locking member 121 can move. More specifically, when the second sleeve 12 is in the first position, the side of the first sleeve 11 away from the first elastic member 13 is flush with the side of the second sleeve 12 away from the first elastic member 13, and the multiple locking members 121 on the second sleeve 12 abut against the limiting boss 21. The limiting boss 21 is used to fix the multiple locking members 121 on the second sleeve 12 to prevent the multiple locking members 121 from rolling and causing the phenomenon of being stuck. When the second sleeve 12 is in the second position, the through hole corresponds to the first avoidance portion 112, so that the locking member 121 in the through hole can move between the through hole and the first avoidance portion 112, so that the male end component 20 can enter the female end component 10, thereby realizing the cooperation between the male end component 20 and the female end component 10. At the same time, the provision of the first avoidance portion 112 can reduce the degree of wear of the parts during the plugging and unplugging process and extend the service life of the female end component 10.

[0064] In this embodiment, when the female component 10 cooperates with the male component 20, the second sleeve 12 needs to move along the axial direction to be unlocked so that the male component 20 can be inserted into the female component 10. When the locking member 121 moves to the first avoidance portion 112, the female component 10 is unlocked and the male component 20 can be inserted into the female component 10. Then the locking member 121 leaves the first avoidance portion 112 again to cooperate with the limiting boss 21 and the limiting protrusion 111 on the male component 20 to lock. When the locking member 121 leaves the first avoidance portion 112, it can leave from both sides of the first avoidance portion 112. However, when the locking member 121 leaves the side of the first avoidance portion 112 away from the limiting boss 21, it will cause the second sleeve 12 to slide excessively, and the female component 10 and the male component 20 cannot be locked. In order to avoid the above situation, in this embodiment, please refer to Figure 5 and Figure 7 The end of the second sleeve 12 away from the first elastic member 13 is folded outward to form a clamping platform 123. When the second sleeve 12 slides along the axial direction of the female end component 10, the clamping platform 123 abuts against the limiting boss 21. Specifically, when the locking member 121 on the second sleeve 12 enters the first avoidance portion 112 on the first sleeve 11, the limiting boss 21 abuts against the clamping platform 123, thereby preventing the second sleeve 12 from continuing to slide and preventing the locking member 121 from rolling out from the other side of the first avoidance portion 112 (i.e., the side of the first avoidance portion 112 away from the limiting boss 21), thereby ensuring the stability of the matching between the female end component 10 and the male end component 20.

[0065] Specifically, in this embodiment, the movable stroke of the clamping platform 123 corresponds to the movable stroke of the locking member 121. This arrangement makes the operation of the female end element 10 simpler. When the clamping platform 123 abuts against the limiting boss 21, the second sleeve 12 cannot continue to slide, which means that the locking member 121 is located in the first avoidance portion 112, and the method for determining whether the installation is in place is simpler and faster.

[0066] It should be noted that, no matter the male end element 20 and the female end element 10 are locked or unlocked, the first sleeve 11 and the second sleeve 12 need to be reset after sliding to facilitate the next operation. Specifically, the present application sets a first elastic member 13 between the first sleeve 11 and the second sleeve 12, and resets the first sleeve 11 and the second sleeve 12 by the rebound force of the first elastic member 13. The specific setting method of the first elastic member 13 is not limited, as long as it can achieve rebound.

[0067] In some embodiments, please refer to Figure 5The first sleeve 11 is provided with an opening, and the end of the first sleeve 11 away from the opening is provided with a first abutting portion 113, and the second sleeve 12 is provided with a second abutting portion 124. One end of the first elastic member 13 abuts against the first abutting portion 113, and the other end of the first elastic member 13 abuts against the second abutting portion 124. In this way, the first sleeve 11 and the second sleeve 12 can slide relative to each other through the first elastic member 13, ensuring that the sliding of the first sleeve 11 and the second sleeve 12 is achieved by relying on the same first elastic member 13, ensuring that the relative position of the first sleeve 11 and the second sleeve 12 will not change, thereby ensuring the stability of the connection between the female end component 10 and the male end component 20.

[0068] In some embodiments, in the first direction (the first direction is the direction from the first position to the second position), the wall thickness of the second abutment portion 124 is reduced, and one end of the first elastic member 13 is sleeved on the second abutment portion 124; in this way, one end of the first elastic member 13 can be sleeved on the first end portion to ensure the stability of the connection between the first elastic member 13 and the second sleeve 12.

[0069] Furthermore, one end of the first sleeve 11 away from the opening is folded inward to form a clamping platform (that is, the first abutment portion 113 is the clamping platform), and the other end of the first elastic member 13 is arranged on the clamping platform, thereby ensuring the stability of the connection between the first elastic member 13 and the first sleeve 11.

[0070] In one embodiment, the first elastic member 13 is a spring.

[0071] It should be noted that, after the male-end component 20 is inserted into the female-end component 10, the second sleeve 12 needs to slide back so that the locking member 121 can be engaged between the limiting protrusion 111 and the limiting boss 21, thereby locking the female-end component 10 and the male-end component 20, that is, when the locking member 121 abuts between the limiting protrusion 111 and the limiting boss 21, the second sleeve 12 needs to stop sliding to avoid causing the locking member 121 to disengage.

[0072] See also Figure 5 In some embodiments, the female end component 10 further includes a valve body 14, the first sleeve 11, the first elastic member 13 and the second sleeve 12 are sleeved on the valve body 14, the first sleeve 11 is movably connected to the valve body 14, and the second sleeve 12 is movably connected to the valve body 14. Specifically, a receiving groove is formed on one side of the valve body 14, the first sleeve 11 is disposed in the receiving groove, the first elastic member 13 is placed in the first sleeve 11, and then the second sleeve 12 is disposed in the first sleeve 11, so that the first elastic member 13 abuts between the first sleeve 11 and the second sleeve 12.

[0073] For more details, please refer to 5 and Figure 7A clamping portion 125 is provided on the inner wall of the second sleeve 12 , and a clamping fitting portion 141 is provided on the outer wall of the valve body 14 . The clamping fitting portion 141 cooperates with the clamping portion 125 to relatively fix the valve body 14 and the second sleeve 12 . In this embodiment, the sliding back of the second sleeve 12 is driven by the rebound force of the first elastic member 13. When the second sleeve 12 drives the locking member 121 to enter the first avoidance portion 112, the first elastic member 13 is compressed by the second sleeve 12. When the male end component 20 is clamped to the female end component 10, the first elastic member 13 rebounds, driving the second sleeve 12 to slide back. When the locking member 121 on the second sleeve 12 slides to between the limiting protrusion 111 and the limiting boss 21, it is clamped by the limiting protrusion 111 and the limiting boss 21. At this time, the clamping portion 125 cooperates with the clamping matching portion 141, thereby fixing the second sleeve 12 on the valve body 14, thereby limiting the second sleeve 12 from continuing to slide along the second direction (the second direction is the direction from the second position to the first position), preventing the second sleeve 12 from continuing to slide, thereby locking the female end component 10 and the male end component 20.

[0074] In this embodiment, the first sleeve 11 has a third position and a fourth position relative to the valve body 14. When the first sleeve 11 is in the third position, the end of the first sleeve 11 abutting against the first elastic member abuts against the valve body 14. When the first sleeve 11 is in the fourth position, the first sleeve 11 compresses the first elastic member 13 so that the locking member 121 is separated from the limiting protrusion 111. Specifically, when the female end element 10 and the male end element 20 are locked in cooperation, the second sleeve 12 moves along the axial direction of the female end element 10, and the first sleeve 11 is prohibited from being immobile (the first sleeve is in the third position); when the female end element 10 and the male end element 20 are unlocked, the first sleeve 11 moves to the fourth position along the axial direction of the female end element 10, and the second sleeve 12 is stationary. At this time, the first avoidance portion 112 on the first sleeve corresponds to the through hole on the second sleeve 12, so that the locking member 121 can move between the through hole and the first avoidance portion 112. Such arrangement enables the first sleeve 11 and the second sleeve 12 to move independently without interference with each other, thereby preventing the movement of one of them from driving the other to move and causing a hand injury.

[0075] In this example, please continue to refer to Figure 5 The female end component 10 also includes a valve core 16, a first sleeve 11, a second sleeve 12, a first elastic member 13 and a valve body 14 are integrated on the valve core 16. Specifically, the first sleeve 11 is arranged on the valve core 16, the second sleeve 12 is arranged in the first sleeve 11, the first elastic member 13 elastically connects the first sleeve 11 and the second sleeve 12, one end of the valve body 14 is arranged on the valve core 16, and the other end passes through the first sleeve 11 and is connected with the second sleeve 12.

[0076] When the female end component 10 and the male end component 20 are locked, the second sleeve 12 slides along the axial direction of the female end component 10 toward the valve core 16. During the sliding process of the second sleeve 12, since the first sleeve 11 is connected to the valve core 16, the first sleeve 11 is limited by the valve core 16, so that the first sleeve 11 cannot move. When the female end component 10 and the male end component 20 are unlocked, the first sleeve 11 slides away from the valve core 16. During the sliding process of the first sleeve 11, since the second sleeve 12 is connected to the valve body 14, it is limited by the valve body 14, so that the second sleeve 12 cannot move. In this way, the first sleeve 11 and the second sleeve 12 can move independently without interference with each other, so as to avoid the movement of one sleeve leading to the movement of the other sleeve, resulting in a hand-beating.

[0077] It should be noted that the number of the locking members 121 on the second sleeve 12 is not limited and can be selected according to actual conditions. In the present embodiment, the number of the locking members 121 is n, where n≥3.

[0078] As a preferred embodiment, six locking members 121 are provided on the second sleeve 12, and the six locking members 121 are evenly arranged on the second sleeve 12, so as to ensure the uniformity of force on the female end element 10. The connection method between the locking member 121 and the second sleeve 12 can refer to the conventional settings in the field, and will not be repeated here.

[0079] In some embodiments, the female end element 10 further includes a first spring, a ejector pin and a plurality of seals. The arrangement and connection of the first spring, the ejector pin and the plurality of seals may refer to conventional arrangements in the art and will not be described in detail here.

[0080] According to a second aspect of the present application, a male end component 20 is provided. Fig. 9 and Fig.10 This is a schematic structural diagram of an embodiment of the male end component 20 provided in the present application.

[0081] See also Fig. 9 The male end component 20 provided in the present application is used for plugging and matching with the above-mentioned female end component 10.

[0082] See also Fig. 9 and Fig.10 A limiting boss 21 is provided on the outer wall of the male end component 20. The limiting boss 21 is used to abut against the locking member 121 during the process of inserting the male end component 20 into the female end component 10 to push the second sleeve 12 to move axially.

[0083] Specifically, see Fig.10The limiting boss 21 includes a first portion 211, a second portion 212 and a third portion 213 connected in sequence, wherein the first portion 211 is arranged close to the female end component 10, and the second portion 212 is arranged between the first portion 211 and the third portion 213, wherein the first portion 211 is arranged in an inclined surface on the side close to the female end component 10, and the inclined surface of the first portion 211 is closer to the axis of the male end component 20 than the other end at one end close to the female end component 10. The third portion 213 is also arranged in an inclined surface on the side away from the female end component 10, and the inclined surface of the third portion 213 is closer to the axis of the male end component 20 than the other end at one end close to the female end component 10.

[0084] Specifically, when the male end element 20 is inserted into the female end element 10, the first portion 211 abuts against the locking piece 121 on the female end element 10, pushing the locking piece 121 to move in the direction close to the first elastic piece 13. Since the locking piece 121 is arranged on the second sleeve 12, the second sleeve 12 is driven to slide in the direction close to the first elastic piece 13, and the first elastic piece 13 is compressed. When the locking piece 121 moves to correspond to the first avoidance portion 112, the male end element 20 continues to move, causing the locking piece 121 to enter the first avoidance portion 112. At this time, the second portion 212 corresponds to the first avoidance portion 112, so that the locking piece 121 is located in the first avoidance portion 112. At this time, the clamping platform 123 of the second sleeve 12 is aligned with the limiting boss 2 of the first sleeve 11. 1 abuts, and the male end component 20 cannot move further, which means that the male end component 20 and the female end component 10 are matched to a suitable position. At this time, stop applying external force to the male end component 20. After the external force disappears, the first elastic member 13 rebounds back, pushing the second sliding member to slide away from the first elastic member 13, and the second sleeve 12 drives the locking member 121 to slide, so that the locking member 121 leaves the slide groove. When the locking member 121 is driven to between the limiting boss 21 and the third part 213, the snap-fitting portion 125 on the second sleeve 12 and the snap-fitting portion 141 on the valve body 14 snap-fit ​​to prevent the second sleeve 12 from continuing to slide, so that the locking member 121 is abutted between the limiting boss 21 and the third part 213, and the male end component 20 and the female end component 10 are locked.

[0085] It should be noted that the inclination angles of the first portion 211 and the third portion 213 may refer to conventional settings in the art, and will not be described in detail here.

[0086] In some embodiments, please refer to Fig. 9 and Fig.10 The male end component 20 is provided with a second avoidance portion 22, which is located on one side of the limiting boss 21. The second avoidance portion 22 is used to avoid the locking member 121 so that the locking member 121 can be just clamped between the third portion 213 and the limiting boss 21.

[0087] Furthermore, the inclined surface of the third portion 213 constitutes a groove wall of the second avoidance portion 22. During the actual clamping process, the groove wall on one side of the second avoidance portion 22 close to the limiting protrusion 111 is used to abut and fix with the locking member 121 after the male end component 20 is inserted into the female end component 10.

[0088] In some embodiments, see Figure 5 and Fig. 9 , a second elastic member 15 is provided in the female end component 10, and in the locked state, the second elastic member 15 is compressed between the male end component 20 and the female end component 10. In the unlocked state, the second elastic member 15 pushes the male end component 20 under the action of the elastic restoring force, so that the male end component 20 is separated from the female end component 10.

[0089] In some embodiments, the second elastic member 15 includes a spring.

[0090] According to the fourth aspect of the present application, a vehicle is provided, the vehicle includes the above-mentioned connector 100, the connector 100 includes the above-mentioned female end element 10 and male end element 20, the specific structure of the female end element 10 and the male end element 20 can refer to the above-mentioned embodiment, the connector 100 has all the beneficial effects of the above-mentioned female end element 10 and the male end element 20, and the present application will not repeat them here; similarly, since the vehicle includes the connector 100, the vehicle also has all the beneficial effects of the above-mentioned connector 100, and the present application will not repeat them here.
