Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to an insertion structure and a connector. Background Art

[0002] A connector is a connection element commonly used in electromechanical equipment. In traditional technology, connectors usually include two terminal structures, which are plugged into each other and electrically conductive to transmit current or signals. The terminal structure of the current connector has a similar structural design, that is, the terminal structure includes an outer shell, an inner sleeve and a rubber core component. When the terminal structure is plugged in, the rubber core components of the two terminal structures are electrically connected, the inner sleeve is sleeved outside the rubber core component and is used to fix the rubber core component, and the outer shell is sleeved outside the inner sleeve to provide waterproof, dustproof, positioning or plug-in guide functions for the inner sleeve and the rubber core component.

[0003] Currently, the outer shell and the inner sleeve are usually connected and fixed by ultrasonic fusion. However, when the above connector is used in an environment with high-speed movement and vibration, the fusion part is easy to be separated, resulting in an unstable overall structure of the connector. Summary of the invention

[0004] Based on this, it is necessary to provide a plug-in structure and a connector to address the problem of structural instability in current connectors.

[0005] On the one hand, the present application provides an insertion structure, which includes a core plug assembly, a first shell and a second shell, the first shell includes an inner sleeve and a convex portion arranged on the outer periphery of the inner sleeve, the inner sleeve is sleeved outside the core plug assembly, and the outer peripheral side of the convex portion is recessed to form a slot; the second shell is axially clamped with the first shell, the second shell includes an outer shell and a clamping piece, the outer shell is sleeved outside the first shell, the clamping piece is an elastic body, and the clamping piece includes a supporting body and an external suspension, the supporting body protrudes from the inner wall surface of the outer shell, and the external suspension The body is connected to one end of the support body away from the inner wall of the shell, and extends out relative to the support body along the axial direction of the shell; when the second shell is clamped with the first shell, the outer suspension body is abutted by the outer wall of the convex portion and flipped and deformed to the side where the inner wall of the shell is located, so as to guide the clamping part to be clamped into the slot as a whole; after the second shell is clamped with the first shell, when one of the two sides of the support body and the outer suspension that are arranged back to back to each other is abutted by the groove wall on one side of the groove, the other can abut the groove wall on the other side of the groove.

[0006] In one embodiment, the inner sleeve includes a first sleeve section and a second sleeve section connected axially end to end, the clamping groove is arranged on the first sleeve section, the outer diameter of the second sleeve section is larger than the outer diameter of the first sleeve section, the outer sleeve is sleeved on the second sleeve section and is spaced from the first sleeve section, and the clamping member is located between the outer sleeve and the first sleeve section;

[0007] Along the axial direction of the insertion structure, the outer suspension extends outward relative to the support body toward the side close to the second sleeve section, and the second shell moves from the end where the first sleeve section is located toward the direction close to the second sleeve section, so that the clamping piece is clamped into the slot.

[0008] In one embodiment, the convex portion includes a guide surface, and the outer diameter of the guide surface gradually increases in a direction from the first sleeve segment to the second sleeve segment along the axial direction of the insertion structure.

[0009] In one embodiment, the outer diameter of the second sleeve segment is larger than the maximum outer diameter of the protrusion, the protrusion is located on the outer wall of the first sleeve segment at one end close to the second sleeve segment, the protrusion is recessed and provided with a notch, the end of the second sleeve segment has a step surface, the step surface and the notch together form the slot; after the second shell is clamped together with the first shell, when the side of the support body away from the external suspension is pushed by the groove wall of the notch, the end of the external suspension away from the support body abuts against the step surface.

[0010] In one embodiment, with the support body as the boundary, the outer shell includes a first shell segment and a second shell segment axially connected end to end, the inner diameter of the first shell segment is smaller than the inner diameter of the second shell segment, and the opposite sides of the support body are respectively connected to the inner wall of the first shell segment and the inner wall of the second shell segment.

[0011] In one embodiment, the clamping member is configured to be arranged in a ring shape around a central axis of the second housing, and the clamping groove is configured to be an annular groove.

[0012] In one embodiment, along the axial direction of the insertion structure, the support body has a first size; in a direction perpendicular to the axial direction of the insertion structure, the overhanging body has a second size, and the first size is greater than or equal to the second size.

[0013] In one embodiment, a side of the support body facing away from the external suspension body contacts and abuts against a groove wall surface of the slot; and / or a side of the external suspension body facing away from the support body contacts and abuts against a groove wall surface of the slot.

[0014] In one of the embodiments, a protruding direction of the support body protruding from the inner wall of the outer shell is perpendicular to an extending direction of the overhanging body relative to the support body.

[0015] On the other hand, the present application provides a connector, which includes the plug-in structure as described above.

[0016] In the above-mentioned plug-in structure, the clamping member includes a support body and an external suspension body, the support body is connected to the inner wall of the shell, and the external suspension body is connected to one end of the support body away from the inner wall of the shell, and extends outward relative to the support body axially, so there is a certain gap between the external suspension body and the inner wall of the shell, that is, at least part of the structure of the external suspension body is suspended relative to the inner wall of the shell. Therefore, the external suspension body is more likely to deform and flip when it is abutted. Therefore, when the second shell and the first shell are clamped together, the external suspension body of the clamping member is abutted by the outer side wall of the convex part of the first shell, and can be flipped and deformed to the side where the inner wall of the shell is located, so as to guide the clamping member as a whole to be clamped into the clamping groove, so that the second shell and the first shell form a clamping assembly.

[0017] After the second shell and the first shell are clamped together, when one of the two sides of the support body and the external suspension is abutted by the groove wall on one side of the clamping slot, the other side can abut the groove wall on the other side of the clamping slot. Under the limiting effect of the groove walls on both sides of the clamping slot, the clamping part will no longer flip further, so the probability of the clamping part flipping and falling out of the clamping slot can be reduced, and the stability of the clamping is improved. For example, when the external force causes the second shell and the first shell to move in the opposite direction to the clamping, the side of the support body away from the external suspension is pushed by the groove wall on one side of the clamping slot, and the end of the external suspension away from the support body abuts against the groove wall on the other side of the clamping slot. The groove wall on the side limits the flipping of the external suspension, so that the clamping part is firmly clamped in the clamping slot, and the stability of the clamping is improved.

[0031] See also Figure 1 , Figure 1 The top view of the plug-in structure provided by one embodiment of the present application is shown. The plug-in structure 10 provided by one embodiment of the present application can be used as one side terminal of the connector for electrical connection. The overall structural stability of the plug-in structure 10 allows the connector including the plug-in structure 10 to be used in devices with high movement or vibration.

[0032] See also Figures 2 to 4 In one embodiment, the insertion structure 10 includes a first housing 100, a second housing 200 and a ferrule assembly 300, wherein the ferrule assembly 300 is used to be electrically connected to another terminal of the connector to transmit current or signals. The first housing 100 is sleeved on the outside of the ferrule assembly 300, and the second housing 200 is sleeved on the outside of the first housing 100. The second housing 200 and the first housing 100 are axially clamped and connected and fixed.

[0033] The first housing 100 includes an inner sleeve 110 and a protrusion 120, and the protrusion 120 is arranged on the outer periphery of the inner sleeve 110. The inner sleeve 110 is sleeved on the outside of the ferrule assembly 300, and the outer periphery of the protrusion 120 is recessed to form a card slot 130. The second housing 200 includes an outer shell 210 and a clamping member 220, and the outer shell 210 is sleeved on the outside of the first housing 100, and the clamping member 220 is arranged on the inner wall of the outer shell 210. The clamping member 220 is an elastic body, and the clamping member 220 includes a support body 221 and an outer suspension 222, and the support body 221 protrudes from the inner wall surface of the outer shell 210, and the outer suspension 222 is connected to one end of the support body 221 away from the inner wall of the outer shell 210, and extends relative to the support body 221 along the axial direction O of the outer shell 210. When the second shell 200 is clamped with the first shell 100, the outer suspension 222 is abutted by the outer wall of the protrusion 120 and is turned and deformed toward the side where the inner wall of the shell 210 is located, so as to guide the clamping member 220 to be clamped into the clamping slot 130 as a whole. After the second shell 200 is clamped with the first shell 100, when one of the two sides of the support body 221 and the outer suspension 222 that are arranged opposite to each other is abutted by one side wall of the clamping slot 130, the other can abut the other side wall of the clamping slot 130.

[0034] In the above-mentioned plug-in structure 10, the clamping member 220 includes a support body 221 and an outer suspension 222. The support body 221 is connected to the inner wall of the shell 210, and the outer suspension 222 is connected to one end of the support body 221 away from the inner wall of the shell 210, and extends outward relative to the support body 221 axially, so there is a certain gap between the outer suspension 222 and the inner wall of the shell 210, that is, at least part of the structure of the outer suspension 222 is suspended relative to the inner wall of the shell 210. Therefore, the outer suspension 222 is more likely to deform and flip when it is abutted. Therefore, when the second shell 200 is clamped with the first shell 100, the outer suspension 222 of the clamping member 220 is abutted by the outer side wall of the protrusion 120 of the first shell 100, and can be flipped and deformed to the side where the inner wall of the shell 210 is located, so as to guide the clamping member 220 to be clamped into the clamping slot 130 as a whole, so that the second shell 200 and the first shell 100 form a clamping assembly.

[0035] After the second shell 200 is snapped together with the first shell 100, when one of the support body 221 and the external suspension body 222 is abutted against one side wall of the card slot 130, the other can abut against the other side wall of the card slot 130. Under the limiting action of the two side walls of the card slot 130, the card connector 220 will no longer flip over further, so the probability of the card connector 220 flipping over and falling out of the card slot 130 can be reduced, thereby improving the stability of the card installation. For example, when an external force causes the second shell 200 and the first shell 100 to move in the opposite direction to when they are clamped (i.e., along the direction O2 shown in the drawings of the specification), the side of the support body 221 that is away from the external suspension 222 is pushed by the side groove wall of the clamping slot 130, and the end of the external suspension 222 that is away from the support body 221 is in contact with the other side groove wall of the clamping slot 130. The side groove wall restricts the flipping of the external suspension 222, so that the clamping member 220 is fastened and clamped in the clamping slot 130, thereby improving the clamping stability. In each embodiment, the clamping direction of the second shell 200 and the first shell 100, as well as the movement direction of the clamping member 220 when it is clamped into the clamping slot 130 can be referred to the label O1 in the drawings of the specification.

[0036] Combination Figure 3 and Figure 4 In short, when the clamping member 220 is located outside the slot 130 and the clamping member 220 abuts against the protrusion 120, only one side of the outer suspension 222 is abutted by the protrusion 120, so the clamping member 220 can be relatively freely deformed to be inserted into the slot 130. When the clamping member 220 is inserted into the slot 130, both sides of the slot 130 can abut against the clamping member 220, thereby limiting the flipping of the clamping member 220, reducing the risk of the clamping member 220 flipping out of the slot 130, and improving the stability of the clamping.

[0037] In other words, compared to the card block with a completely solid structure, the card connector 220 provided in the present application is configured with an outer suspension 222. During the card installation process, the outer suspension 222 can be flipped and deformed to guide the card connector 220 to be inserted into the card slot 130 as a whole. After the card installation, the outer suspension 222 can abut against the slot wall of the card slot 130 to provide a limiting effect. This configuration allows the card connector 220 to take into account both the smoothness of the card installation and the limiting stability after the card installation.

[0038] See also Figure 3It is easy to understand that in each embodiment of the present application, the axial length of the clamping member 220 can be configured to be equal to the axial length of the slot 130. Therefore, after the clamping member 220 is inserted into the slot 130, the sides of the support body 221 and the outer suspension 222 that are away from each other can simultaneously abut the groove walls on both sides of the slot 130. However, due to certain errors in production and manufacturing, if the axial length dimensions of the two are configured to be exactly the same, there is a situation where the clamping member 220 cannot be inserted into the slot 130 due to the error. In other words, such a setting requires high production and processing accuracy. Therefore, in some embodiments, the axial length of the clamping member 220 can also be configured to be slightly smaller than the axial length of the slot 130. At this time, after the clamping member 220 is inserted into the slot 130, one side of the clamping member 220 can be spaced from the side groove wall of the slot 130. Since the clamping member 220 is an elastic body, when one side of the clamping member 220 (for example, the side where the aforementioned support body 221 is located) is pushed by the groove wall of the slot 130, the clamping member 220 can be deformed, flipped and slightly tilted, so that the overhang 222 flips and tilts and abuts against the groove wall on the other side of the slot 130. At this time, the axial sides of the clamping member 220 can also abut against the groove walls on both sides of the slot 130 at the same time, forming a stable limited clamping. In other words, the clamping member 220 provided in the present application can also accommodate a certain matching clearance, reducing the difficulty of processing.

[0039] See also Figure 5 and Figure 6 In one embodiment, the clamping member 220 is constructed to be arranged in an annular shape around the central axis of the second shell 200, and the slot 130 is constructed as an annular groove. With such a configuration, the annularly arranged clamping member 220 cooperates with the annular slot 130, which can further improve the stability of the clamping. It can be understood that in this embodiment, the support body 221 and the external suspension 222 are both annular, and the eversion of the external suspension 222 in each embodiment is also the outward expansion and flipping of the annular external suspension 222. Of course, in another embodiment, the clamping member 220 can also be constructed to include a plurality of parts arranged at intervals in the direction around the central axis of the second shell 200, and the plurality of parts cooperate with the slot 130 to jointly provide a clamping limiting effect.

[0040] It should be noted that, in addition to the clamping member 220, other axial limiting or axial positioning structures may be generally configured between the first housing 100 and the second housing 200, so that the clamping member 220 is mainly subjected to the external force opposite to the clamping direction. Figure 2 , combined with Figure 6In one embodiment, the first shell 100 further includes a limit ring 101, which is protruding from the outer peripheral side of the first shell 100. When the clamping member 220 is inserted into the clamping slot 130, the end of the second shell 200 abuts against the limit ring 101. The axial O limit provided by the limit ring 101 can reduce the risk of damaging the clamping member 220 due to excessive clamping force during clamping. At the same time, the limit ring 101 can also bear the external force along the clamping direction together with the clamping member 220, or the limit ring 101 is mainly used to bear the external force along the clamping direction to reduce the load of the clamping member 220, so that the clamping member 220 is mainly used to bear the force opposite to the clamping direction.

[0041] See also Figure 3 , combined with Figure 6 In one embodiment, the inner sleeve 110 includes a first sleeve section 111 and a second sleeve section 112, the first sleeve section 111 and the second sleeve section 112 are connected axially end to end, and the clamping groove 130 is arranged in the first sleeve section 111. Along the axial direction O of the plug-in structure 10, the outer suspension 222 extends outward relative to the support body 221 to the side close to the second sleeve section 112, and the second shell 200 moves from the end where the first sleeve section 111 is located to the direction close to the second sleeve section 112, so that the clamping member 220 is clamped into the clamping groove 130. The outer diameter of the second sleeve section 112 is greater than the outer diameter of the first sleeve section 111, that is, the second sleeve section 112 is thicker than the first sleeve section 111. The outer shell 210 can be sleeved on the second sleeve section 112 and spaced from the first sleeve section 111, and the clamping member 220 is located between the outer shell 210 and the first sleeve section 111. Since the housing 210 is sleeved on the thicker second sleeve section 112, it can be spaced apart from the first sleeve section 111, so that the clamping member 220 can be arranged between the housing 210 and the first sleeve section 111. Thus, the clamping member 220 can smoothly move to a position for clamping with the clamping slot 130.

[0042] Of course, in another embodiment, a slide groove (not shown in the figure, the same below) may be provided on the outer periphery of the first sleeve section 111 for the arrangement and movement of the clamping member 220. That is, the clamping member 220 may move along the slide groove to a position where it is clamped with the clamping slot 130.

[0043] See also Figures 3 to 6In one embodiment, the outer diameter of the second sleeve section 112 is greater than the maximum outer diameter of the convex portion 120. The convex portion 120 is located on the outer wall of the first sleeve section 111 near one end of the second sleeve section 112, and the convex portion 120 is recessed to form a notch 121. The end of the second sleeve section 112 has a step surface 112a, and the step surface 112a and the notch 121 are surrounded to form the above-mentioned clamping groove 130. After the second shell 200 and the first shell 100 are clamped together, when the side of the support body 221 away from the outer suspension 222 is pushed by the groove wall of the notch 121, the end of the outer suspension 222 away from the support body 221 abuts against the step surface 112a. Since the outer diameter of the second sleeve section 112 is greater than the maximum outer diameter of the convex portion 120, the step surface 112a located at the end of the second sleeve section 112 has a larger radial dimension than the side groove wall of the notch 121, so the step surface 112a can provide a more sufficient abutment and limiting effect. Therefore, by providing the step surface 112 a to abut against the outer suspension 222 , the overturning of the outer suspension 222 can be fully limited, thereby improving the clamping stability.

[0044] See also Figure 3 and Figure 4 In one embodiment, the protrusion 120 is protruding from the first sleeve section 111, and the inner ring of the clamping member 220 can be spaced apart from the outer periphery of the first sleeve section 111. The inner diameter of the clamping member 220 can be equal to the outer diameter of the bottom wall of the notch 121, or the inner diameter of the clamping member 220 can be slightly larger than the outer diameter of the bottom wall of the notch 121, so that after the clamping member 220 is inserted into the slot 130, the inner ring of the clamping member 220 fits the bottom wall of the notch 121 or there is only a small gap.

[0045] See also Figure 3 , combined with Figure 6 In one embodiment, the convex portion 120 includes an introduction surface 122, and the outer diameter of the introduction surface 122 gradually increases in the direction from the first sleeve section 111 to the second sleeve section 112 along the axial direction O of the insertion structure 10 (i.e., along the direction O1 shown in the drawings of the specification). Therefore, during the clamping process, the introduction surface 122 can gradually push the clamping member 220, so that the clamping member 220 is turned over and deformed and smoothly clamped into the clamping slot 130.

[0046] Please continue reading Figure 3 In one embodiment, the side of the support body 221 facing away from the outer suspension body 222 contacts and abuts against the groove wall surface of the slot 130 to improve the stability of the abutment between the two. Further, the side of the support body 221 abutting against the groove wall of the slot 130 can be perpendicular to the axial direction O of the insertion structure 10. Correspondingly, the side groove wall of the slot 130 can also be perpendicular to the axial direction O of the insertion structure 10.

[0047] Similar to the above, in one embodiment, the side of the external suspension 222 facing away from the support body 221 contacts and abuts against the groove wall surface of the slot 130 to improve the stability of the abutment between the two and limit the flipping of the external suspension 222. Further, the side of the external suspension 222 abutting against the groove wall of the slot 130 can be perpendicular to the axial direction O of the insertion structure 10. Similarly, the side groove wall of the slot 130 can also be perpendicular to the axial direction O of the insertion structure 10.

[0048] See also Figures 3 to 5 In one embodiment, the outer shell 210 includes a first shell segment 211 and a second shell segment 212 with the support body 221 as the boundary, and the first shell segment 211 and the second shell segment 212 are axially connected end to end. The inner diameter of the first shell segment 211 is smaller than the inner diameter of the second shell segment 212, and the two opposite sides of the support body 221 are respectively connected to the inner wall of the first shell segment 211 and the inner wall of the second shell segment 212. Compared with the configuration that the support body 221 is connected to the position with the same inner diameter in the outer shell 210, the support body 221 in this embodiment is located at the transition connection between the first shell segment 211 and the second shell segment 212 with different inner diameters, and the support body 221 can have a relatively larger connection and matching area PL with the outer shell 210, so the support body 221 is less likely to break.

[0049] Furthermore, in the second shell 200 , the second shell segment 212 and the second sleeve segment 112 may be fitted and sleeved together, and the first shell segment 211 and a partial area of ​​the second shell segment 212 may be spaced apart from the first sleeve segment 111 .

[0050] Please continue reading Figure 3 In one embodiment, along the axial direction O of the plug-in structure 10, the support body 221 has a first dimension S1. In the direction perpendicular to the axial direction O of the plug-in structure 10, the outer suspension 222 has a second dimension S2. The first dimension S1 is greater than or equal to the second dimension S2. In short, in their respective extension directions, the support body 221 is thicker than the outer suspension 222, so that the support body 221 can provide sufficient support and connection, thereby reducing the risk of the support body 221 breaking and causing the card connection to fail. At the same time, the outer suspension 222 is relatively thin and can be easily deformed under the abutment of the introduction surface 122 of the protrusion 120 to guide the entire card connector 220 to smoothly snap into the card slot 130.

[0051] See also Figure 3 and Figure 4 In one embodiment, the protruding direction of the support body 221 protruding from the inner wall of the housing 210 (i.e., the extending direction of the support body 221) is perpendicular to the extending direction of the outer suspension 222 relative to the support body 221 (i.e., the extending direction of the outer suspension 222). For example, the support body 221 protrudes inwardly along the radial direction of the second housing 200. As mentioned above, the outer suspension 222 extends outward along the axial direction O of the second housing 200.

[0052] See also Figure 3 and Figure 4 In one embodiment, the clip 220 may be constructed to be L-shaped.

[0053] See also Figure 2 In one embodiment, the ferrule assembly 300 includes an insulator 310 and a conductive terminal 320 , the first housing 100 is sleeved outside the insulator 310 , and the conductive terminal 320 is disposed through the insulator 310 . Further, the first housing 100 may be fixedly connected to the insulator 310 .

[0054] Or see Figure 2 In another embodiment, the first housing 100 can be used in conjunction with other structures to fix the insulator 310 and the conductive terminal 320 inserted into the insulator 310. For example, the plug-in structure 10 further includes a tail housing 400 and a tail wire sleeve 500. The tail wire sleeve 500 is inserted through the first housing 100 to cooperate with the first housing 100 to clamp and fix the insulator 310. The tail housing 400 is sleeved outside the first housing 100 and is located in the inner circle of the second housing 200. The tail housing 400 is screwed to the tail of the first housing 100 and abuts against the end of the tail wire sleeve 500 away from the first housing 100, so that the tail wire sleeve 500 is fixed relative to the first housing 100.

[0055] An embodiment of the present application further provides a connector, which may include the plug-in structure 10 as described in each embodiment. Further, both ends of the connector may be configured as the plug-in structure 10 as described in each embodiment. Furthermore, the ferrule assembly 300 and other related parts for fitting and plugging included in the two plug-in structures 10 may be configured to be different, so that the two can be fitted and plugged and electrically connected.
