Description

Technical Field

[0001] This invention relates to the field of conductive connectors, and more particularly to a flexible plug-in structure and a self-aligning conductive connector having the same structure. Background Technology

[0002] Conductive connectors are fundamental components in electrical systems used for electrical connections, enabling the transmission and exchange of electrical energy or signals.

[0003] Chinese Patent Application No. 201820510049.5 discloses an electrical connector, including a female pin connector having a sleeve; a crown spring member inserted into the sleeve, the crown spring member including two rings and a plurality of spring plates extending integrally from the two rings and spanning between the two rings, each spring plate having an inner wall and a plurality of bends and protrusions bending towards the inner wall; and a male pin connector having a pin inserted into the sleeve, the crown spring member being clamped between the sleeve and the pin, the plurality of bends and protrusions abutting against the pin.

[0004] In the above scheme, the pin is inserted into the sleeve, and the crown spring elastically clamps the pin and contacts the sleeve, ensuring stable insertion of the electrical connector. At the same time, the pin and the sleeve are electrically connected through the crown spring.

[0005] However, common crown springs have a fixed insertion force, and in order to ensure the stability of the electrical connection, the insertion force often needs to be set relatively large. This can lead to the risk of damaging the surface of the crown spring or the pin (plug post) during insertion, causing excessively deep scratches on the surface, increasing the contact resistance between the two, or damaging the protective coating, resulting in oxidation, corrosion, open circuit failure, etc. Summary of the Invention

[0006] The first objective of this invention is to address the shortcomings of existing technologies where, in order to ensure the stability of electrical connections, the insertion force of the crown spring often needs to be set relatively large, which leads to the risk of damaging the crown spring or the surface of the pin (plug post) during insertion. This invention provides an elastic plug-in structure that facilitates the insertion of plug posts to reduce the risk of surface wear while ensuring elastic clamping strength.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A resilient plug-in structure includes a plug-in post, a plug-in housing, and a plug-in slot on the plug-in housing for inserting the plug-in post. A crown spring is provided in the plug-in slot to elastically clamp the plug-in post when it is inserted. A switching structure is provided between the crown spring and the plug-in slot, which drives the crown spring to elastically open to facilitate insertion of the plug-in post when it is not inserted, and drives the crown spring to elastically retract to clamp the plug-in post after insertion. The switching structure includes two insulating rings concentrically disposed inside both ends of the crown spring and fixed to the plug-in slot for the plug-in post to pass through. An airbag is provided on the outer ring wall of the two insulating rings, which drives the crown spring to open or contract when it expands. An opening and closing structure is provided between the insulating ring and the plug housing, which normally closes the two airbags and opens the two airbags when the plug is inserted to the preset position. An injection structure is provided inside the insulating ring to store insulating glue and squeeze out the insulating glue to fix the crown spring and the insulating ring when the crown spring elastically retracts. Both ends of the crown spring extend outward and are provided with an elastic conductive structure that makes the crown spring electrically connected to the inner wall of the plug groove and increases the elastic retraction strength of the crown spring.

[0008] Using the above scheme, when the plug is not inserted, the two ends of the crown spring are temporarily in an elastically open state under the action of the inflated airbag, which increases the inner diameter of the crown spring, reduces the insertion resistance of the plug, and reduces the risk of surface scratches. The flexible and uniform opening of the airbag drives the crown spring to open, reducing damage to the crown spring. After the plug is inserted into the preset position, the opening and closing structure opens the airbag. The airbag retracts, which reduces or eliminates the force driving the crown spring to open. Under the combined action of the crown spring's own elasticity and the elastic conductive structure, the two ends of the crown spring are tightly clamped to the insulating ring, so that the spring's spring clips are elastically held on the plug, ensuring the elastic clamping strength of the crown spring on the plug. The elastic conductive structure also ensures that the crown spring always maintains an electrical connection with the inner wall of the plug groove when opening or retracting. At the same time, during the retraction of the crown spring, the insulating glue is released and squeezed out to fix the crown spring on the insulating ring, enhancing stability and anti-loosening ability, and further ensuring the elastic clamping strength of the crown spring on the plug. This achieves the goal of facilitating the insertion of plugs to reduce the risk of surface wear while ensuring elastic clamping strength.

[0009] Preferably, the opening and closing structure includes an airway that connects the airbag to the outside, a plug that can open or close the airway and is movable along the insertion direction of the plug, and a transmission structure provided in an insulating ring near the bottom of the plug groove that drives the plug to move to open the airway when the plug is inserted to a preset position.

[0010] Using the above solution, when the plug is inserted into the preset position, the transmission structure drives the block to move to the position where the airway is opened, the gas in the airbag is discharged, the airbag retracts, and the airbag can be opened by inserting the plug in this necessary step. No additional operation is required, and the operation is simple.

[0011] Preferably, the transmission structure includes a drive block that extends partially under normal conditions and is telescopically disposed within the insulating ring along the insertion direction of the plug, and a connecting rod whose two ends are respectively connected to the block and the drive block. The insulating ring is provided with a guide clearance space for the block, the drive block and the connecting rod to move linearly.

[0012] Using the above solution, when the plug is inserted into the preset position, it pushes the drive block to retract, and the connecting rod drives the block to move to open the air passage. The structure is simple, and the guide clearance space is matched with the linear guide movement of the block, drive block and connecting rod, resulting in high reliability.

[0013] Preferably, the preset position in which the plug is inserted into the plug slot is the position in which the plug pushes the drive block to move until the drive block is completely retracted into the guide clearance space.

[0014] Preferably, the glue injection structure includes a accommodating cavity disposed within the insulating ring and connected to the end of the airway away from the airbag, a glue injection hole disposed on the outer ring wall of the insulating ring to connect the accommodating cavity with the outside, and a reservoir capsule disposed within the accommodating cavity to store insulating glue. A pushing structure is disposed between the accommodating cavity and the reservoir capsule to first puncture the reservoir capsule to release the insulating glue and then squeeze the insulating glue through the glue injection hole to the space between the insulating ring and the crown spring. The pushing structure is driven by the positive pressure released within the airbag after the airway is opened.

[0015] The above scheme, using the combined operation of the storage capsule and the actuation structure, achieves sealed storage and on-demand release of the insulating adhesive, preventing premature curing or contamination. The positive pressure released from the airbag drives the actuation structure, first causing the storage capsule to rupture and release the insulating adhesive, then pushing the adhesive through the injection hole between the two ends of the insulating ring and the crown spring, requiring no additional power source.

[0016] Preferably, the actuating structure includes a sealing plate that is radially and reciprocally moved within the accommodating cavity along an insulating ring, a reservoir capsule is disposed between the sealing plate and the injection hole, and the side of the accommodating cavity away from the injection hole is connected to the air passage, and a needle is provided on the side of the sealing plate near the reservoir capsule.

[0017] Using the above method, the positive pressure released by the airbag drives the sealing plate to move closer to the injection hole. The piercing needle moves with the sealing plate and punctures the storage capsule, releasing the insulating glue into the cavity. As the sealing plate continues to move, the glue is squeezed out through the injection hole.

[0018] Preferably, the outer ring walls of the two insulating rings are respectively provided with concentric annular grooves for accommodating the airbags, and the glue injection holes are provided on the outer ring walls of the two insulating rings and located on the opposite side of the two annular grooves.

[0019] With the above design, the airbag is placed inside the annular groove. After the airbag contracts, it is stored within the annular groove, reducing the impact on the clamping of the crown spring's ends onto the insulating ring. The glue injection hole is located outside the annular groove. During the clamping process between the crown spring and the insulating ring, excess insulating glue can be squeezed into the annular groove, preventing insulating glue from overflowing onto the crown spring's spring contacts and affecting the crown spring's performance.

[0020] Preferably, the glue-injection structure has at least one set of crown springs spaced axially.

[0021] Using the above scheme, the above effect can be achieved by setting up one set. Multiple sets of glue injection structures are distributed circumferentially, which increases the uniformity of the insulating glue extrusion and makes the fixing effect more stable.

[0022] Preferably, the elastic conductive structure includes an abutment plate disposed between the outer ring wall at both ends of the crown spring and the inner wall of the insertion groove, and a conductive spring piece connected to the crown spring and the abutment plate at both ends respectively, which drives the crown spring to clamp onto the insulating ring and simultaneously drives the abutment plate to abut against the inner wall of the insertion groove. The abutment plate and the conductive spring piece are evenly spaced in several groups around the crown spring axis.

[0023] Using the above scheme, the conductive spring causes the crown spring to clamp onto the insulating ring while simultaneously causing the abutment plate to abut against the inner wall of the insertion slot, ensuring the electrical connection between the crown spring and the insertion slot, and providing a certain degree of elasticity, thereby enhancing the structural strength and durability of the crown spring when it is opened and retracted.

[0024] The second objective of this invention is to provide a self-aligning conductive connector having the above-mentioned elastic plug-in structure, comprising a first conductor and a second conductor. The first conductor includes a plug-in housing with a T-shaped cross-section. A plug-in slot is provided on the vertical section of the plug-in housing, and a conductive housing is sleeved on the horizontal section of the plug-in housing. A first busbar is fixed on the conductive housing. Wave springs are provided on both sides of the plug-in housing along the axial direction of the plug-in post and between the plug-in housing and the conductive housing, allowing both to move elastically in the Z-axis direction. A sliding space exists between the conductive housing and the plug-in housing for the plug-in housing to move in the X-axis and Y-axis directions within the conductive housing. The second conductor includes a plug-in post with an insulating housing provided on the outside for the vertical section of the plug-in housing to be inserted into. A second busbar is fixed on the end of the plug-in post away from the plug-in housing.

[0025] By adopting the above scheme, a flexible plug-in structure is applied to the self-aligning conductive connector to ensure a stable electrical connection between the plug-in housing and the plug-in post. Simultaneously, the plug-in housing can move freely in the X and Y axes and move elastically in the Z axis, achieving three-dimensional floating alignment to accommodate installation errors.

[0026] This invention, by employing the above technical solutions, achieves significant technical effects: When the plug is not inserted, the two ends of the crown spring are temporarily in an elastically open state under the action of the inflated air bladder, reducing the insertion resistance of the plug and minimizing the risk of surface scratches; after the plug is inserted into the preset position, the air bladder retracts, reducing or eliminating the force driving the crown spring to open. Under the combined action of the crown spring's own elasticity and the elastic conductive structure, the two ends of the crown spring tightly grip the insulating ring, ensuring the elastic clamping strength of the crown spring on the plug. The elastic conductive structure also ensures that the crown spring maintains electrical connection with the inner wall of the plug groove during opening or retraction. Simultaneously, during the retraction of the crown spring, insulating adhesive is released and extruded to fix the crown spring to the insulating ring, enhancing stability and anti-loosening ability, further ensuring the elastic clamping strength of the crown spring on the plug. This achieves the goal of facilitating plug insertion to reduce the risk of surface wear while ensuring elastic clamping strength. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] A flexible plug-in structure and a self-aligning conductive connector having the structure, see reference. Figures 1 to 10The system includes a first conductor and a second conductor. The first conductor includes a plug-in housing 2 with a T-shaped cross-section. A plug-in groove 3 is provided on the vertical section 202 of the plug-in housing 2, and a conductive housing 22 is sleeved on the horizontal section 201 of the plug-in housing 2. A first busbar 26 is fixed on the conductive housing 22. Wave springs 24 are provided on both sides of the plug-in housing 2 along the axial direction of the plug-in post 1 and between the plug-in housing 2 and the conductive housing 22, which elastically abut against both the plug-in housing 2 and the conductive housing 22, so that the plug-in housing 2 can move elastically relative to the conductive housing 22 in the Z-axis direction. There is a sliding space 25 between the conductive housing 22 and the plug-in housing 2 for the plug-in housing 2 to move in the X-axis and Y-axis directions within the conductive housing 22. The Z-axis direction is parallel to the axial direction of the vertical section 202 of the plug-in housing 2, and the X-axis and Y-axis directions are parallel to the radial direction of the vertical section 202 of the plug-in housing 2. The second conductor includes a plug post 1. An insulating shell 23 is provided outside the plug post 1 for the vertical section 202 of the plug housing 2 to be inserted into. When the vertical section 202 of the plug housing 2 is inserted into the insulating shell 23, the plug post 1 is inserted into the plug groove 3. In this embodiment, the plug post 1 includes a conductive post 102. A guide post 101 is coaxially provided at one end of the conductive post 102 near the plug housing 2. A second busbar 27 is fixedly provided at the end of the conductive post 102 away from the plug housing 2. The plug housing 2 is provided with a clearance groove 4 for the guide post 101 to be inserted into. The plug housing 2, conductive shell 22, wave spring 24, first busbar 26, conductive post 102, and second busbar 27 are all made of conductive material; copper can be used in this embodiment. The insulating shell 23 and guide post 101 are made of insulating material; plastic can be used in this embodiment. The first busbar 26 and conductive shell 22 are connected by riveting, and the conductive post 102 and second busbar 27 are fastened together by bolts. The plug-in housing 2 can move freely in the X and Y axis directions relative to the conductive housing 22, and can move elastically in the Z axis direction to achieve three-dimensional floating centering and adapt to installation errors.

[0031] A crown spring 5 is provided inside the insertion slot 3 to elastically clamp the insertion post 1 when it is inserted. In this embodiment, the crown spring 5 is elastically clamped on the conductive post 102. Insulating rings 8 are concentrically arranged inside both ends of the crown spring 5, and the insulating rings 8 are fixedly connected to the insertion slot 3. The inner diameter of the insulating rings 8 is larger than the outer diameter of the guide post 101 and the conductive post 102 to prevent interference with the movement of the insertion post 1 and ensure that the insertion post 1 can be smoothly inserted into the insertion slot 3. Annular grooves 9 are concentrically recessed on the outer ring walls of the two insulating rings 8. An air bladder 10 is fixedly arranged at the bottom of the annular groove 9. The air bladder 10 is an annular air bladder. When the air bladder 10 inflates, part of it protrudes outside the annular groove 9, driving both ends of the crown spring 5 to open, thereby driving the entire crown spring 5 to open. When the air bladder 10 contracts, it is stored inside the annular groove 9, and the crown spring 5 can retract so that both ends of the crown spring 5 are clamped onto the insulating rings 8. An abutment plate 6 is provided between the outer ends of the crown spring 5 and the insertion slot 3. A conductive spring piece 7 is provided between the end of the crown spring 5 and the abutment plate 6, with its two ends respectively connected to the crown spring 5 and the abutment plate 6. Under normal conditions, the conductive spring piece 7 drives the two ends of the crown spring 5 to clamp onto the insulating ring 8, while simultaneously driving the abutment plate 6 to abut against the inner wall of the insertion slot 3. In this embodiment, the conductive spring piece 7 has a U-shaped cross-section, and the openings of the conductive spring pieces 7 on both ends of the crown spring 5 are arranged opposite each other. Several sets of abutment plates 6 and conductive spring pieces 7 are evenly spaced around the axial direction of the crown spring 5; in this embodiment, nine sets are provided. In this embodiment, the abutment plates 6 and conductive spring pieces 7 are made of the same conductive material as the crown spring 5.

[0032] An accommodating cavity 16 is provided inside the insulating ring 8. An injection hole 17 is provided on the outer ring wall of the insulating ring 8 to connect the accommodating cavity 16 with the outside. The injection hole 17 on the insulating ring 8 near the relief groove 4 is located above the annular groove 9, and the injection hole 17 on the insulating ring 8 away from the relief groove 4 is located below the annular groove 9. That is, the injection holes 17 on the outer ring walls of the two insulating rings 8 are located on opposite sides of the two annular grooves 9. A sealing plate 20 is provided in the accommodating cavity 16 and moves radially and reciprocally along the insulating ring 8. A storage capsule 18 for storing insulating adhesive 19 is provided between the sealing plate 20 and the injection hole 17. A needle 21 is provided on the side of the sealing plate 20 near the storage capsule 18. The accommodating cavity 16, the injection hole 17, the sealing plate 20, the needle 21, and the storage capsule 18 for storing insulating adhesive 19 are arranged at least one set around the insulating ring 8 at axial intervals.

[0033] An insulating ring 8 near the clearance groove 4 has a sliding cavity 28 inside. Air passages 11 are provided inside the insulating ring 8 and the plug-in housing 2. The two airbags 10 on the two insulating rings 8 communicate with the sliding cavity 28 via the air passages 11. Simultaneously, all the accommodating cavities 16 on the two insulating rings 8 on the side furthest from the injection hole 17 are also connected to the sliding cavity 28. A blocking block 12 is movable inside the sliding cavity 28 along the insertion direction of the plug-in post 1. The blocking block 12 can move to block the air passages 11, thus sealing the two airbags 10, or move to expose the air passages 11, thus communicating with the airbags 10. A driving block 13, partially extending under normal conditions, is telescopically provided inside the insulating ring 8 with the blocking block 12 along the insertion direction of the plug-in post 1. A connecting rod 14, with its two ends connected to both, is provided between the driving block 13 and the blocking block 12. A guide clearance space 15 is also provided inside the insulating ring 8 to allow the blocking block 12, driving block 13, and connecting rod 14 to move linearly. The preset position where the plug 1 is inserted into the plug slot 3 is the position where the plug pushes the drive block to move until the drive block is completely retracted into the guide clearance space.

[0034] When the plug post 1 is not inserted, the two ends of the crown spring 5 are temporarily in an elastically open state under the action of the two inflated airbags 10. When the plug post 1 is inserted into the preset position, the push drive block 13 drives the block block 12 to move to open the air passage 11 through the connecting rod 14, so that the inside of the airbag 10 is connected to the accommodating cavity 16. Under the combined action of the airbag 10's own contraction, the elastic restoring ability of the two ends of the crown spring 5 and the restoring elastic force of the conductive spring 7, the air in the airbag 10 enters the accommodating cavity 16 and pushes the sealing plate 20 to move closer to the glue injection hole 17. The needle 21 first punctures the storage capsule 18 to release the insulating glue 19. The insulating glue 19 is then squeezed between the insulating ring 8 and the two ends of the crown spring 5 under the movement of the sealing plate 20. Finally, the two ends of the crown spring 5 are clamped onto the insulating ring 8 and further fixed by the insulating glue 19. The spring piece of the crown spring 5 is elastically clamped onto the conductive post 102, and the abutment plate 6 abuts against the inner wall of the insertion slot 3. While ensuring the insertion strength, the current can pass through the second busbar 27, the conductive post 102, the crown spring 5, the conductive spring piece 7, the abutment plate 6, the insertion shell 2, the wave spring 24, the conductive shell 22 and the first busbar 26 in sequence to form a conductive path for current flow.
