Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector sealing structure and an electrical connector assembly. Background Technology

[0002] Current mainstream interfaces (such as Type 1 / 2, CCS, and GB / T) generally use elastic sealing rings and potting processes for protection, but they face multiple challenges in high-power, complex environments, and frequent usage scenarios, such as:

[0003] Structural design flaws: The sealing ring installation tolerance is sensitive (leakage occurs if the tolerance is exceeded by ±0.15mm); the single-layer seal at the outer shell seams is not sufficiently redundant; and the split design is prone to water seepage paths due to vibration or wear during insertion and removal. For example, after heavy rain, some charging ports may accumulate water inside due to insufficient compression of the seam seal.

[0004] Poor adaptability to dynamic operating conditions: Frequent insertion and removal cause the permanent deformation rate of the sealing ring to exceed 30%, reducing the protection level from IP67 to IP54; Vehicle vibration and the need for coordinated sealing of liquid cooling pipelines increase structural complexity, and liquid cooling leakage may cause short circuit risk.

[0005] Maintenance difficulties: Damage to the seal requires replacement of the entire module, resulting in high maintenance costs and environmental problems. Utility Model Content

[0006] To address the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a sealing structure and assembly for an electrical connector. Utilizing a flange gasket and a sealing cap, the electrical connector is sealed when it is disconnected from the complementary electrical connector. Furthermore, the sealing gasket on the sealing cap can be squeezed into the port of the electrical connector, causing the sealing groove to fit against the inner wall of the port of the complementary electrical connector. This prevents water accumulation inside the port of the electrical connector due to insufficient sealing compression at the joint, thus improving the sealing effect.

[0007] To solve the above-mentioned technical problems, the present invention provides a sealing structure and an assembly for an electrical connector, including a flange gasket and a sealing cover. The flange gasket is detachably connected to the flange of a complementary electrical connector. The sealing cover is connected to a burr extending from one side of the flange gasket, and the sealing cover can be flipped to cover the port of the complementary electrical connector.

[0008] Furthermore, the flange gasket is connected to the flange by bolts.

[0009] Furthermore, the sealing cap includes a cap body and a sealing gasket; the sealing gasket is disposed on one end face of the sealing cap.

[0010] Furthermore, the sealing gasket has a columnar structure, and several sealing grooves extend circumferentially from the column surface.

[0011] Furthermore, the cross-sectional area of ​​the sealing groove is larger than the cross-sectional area of ​​the port of the complementary electrical connector; when the cover is flipped to cover the port of the complementary electrical connector, the sealing gasket can be squeezed into the port of the complementary electrical connector, so that the sealing groove fits against the inner wall of the port of the complementary electrical connector.

[0012] Furthermore, at least one of the flange gaskets is provided with a limiting groove; the flange is provided with a limiting protrusion at a position corresponding to the limiting groove, which is matched with the limiting groove for limiting.

[0013] Furthermore, it also includes a sealing ring; the sealing ring is disposed on the complementary electrical connector at the position where it abuts against the electrical connector, so that when the complementary electrical connector is engaged with the electrical connector, a seal is formed at the position where the complementary electrical connector abuts against the electrical connector.

[0014] This utility model also provides an electrical connector assembly, including an electrical connector, a complementary electrical connector that mates with the electrical connector, and a wire connected to the electrical connector. It also includes the electrical connector sealing structure described in any of the preceding claims.

[0015] Furthermore, the electrical connector has a plug end and a first connection end, and the complementary electrical connector has a complementary plug end that mates with the plug end and a second connection end, both the first connection end and the second connection end being connectable to a circuit board or a wire.

[0016] Furthermore, the complementary electrical connector also includes a first insulating housing and a second terminal inserted into the first insulating housing. The flange gasket is arranged around the outer periphery of the first insulating housing. The first insulating housing has a partition for dividing the space inside the housing into two parts, forming a mating groove near the complementary electrical connector and a mounting groove away from the complementary electrical connector. A sealing ring is provided on the bottom surface of the mating groove. A socket is formed on the partition corresponding to the position of the second terminal for insertion. One end of the second terminal is placed in the mating groove to form the mating end, and the other end of the second terminal is placed in the mounting groove to form the second connection end.

[0017] The sealing structure of this utility model for electrical connectors has at least the following beneficial effects: 1. By using a sealing cover and a flange gasket to achieve sealing of the complementary electrical connector, and by using a sealing ring to achieve sealing when the complementary electrical connectors are engaged, the overall sealing effect of the complementary electrical connector is improved; 2. Through the sealing groove, and the setting that the cross-sectional area of ​​the sealing groove is larger than the cross-sectional area of ​​the port of the complementary electrical connector, when the cover is flipped to cover the port of the complementary electrical connector, the sealing gasket can be squeezed into the port of the complementary electrical connector, thereby making the sealing groove fit with the inner wall of the port of the complementary electrical connector, further improving the sealing effect; 3. The flange gasket and the flange are connected by bolts, which facilitates the disassembly, assembly, and maintenance of the sealing structure; 4. The flange gasket has three limiting grooves on its three sides without protruding flash, and the flange has three corresponding limiting protrusions; the three limiting grooves can cooperate with the limiting protrusions to limit the flange gasket on the flange, thereby making the contact between the flange gasket and the flange tighter and less prone to loosening, thus improving the sealing effect of the flange gasket.

Detailed Implementation

[0042] The present invention will be further described below with reference to the accompanying drawings.

[0043] like Figures 1 to 20 As shown, this utility model provides a sealing structure and assembly for an electrical connector. Utilizing a flange gasket 6 and a sealing cap 7, the electrical connector 4 seals the complementary electrical connector 5 when it is disconnected from the complementary electrical connector 5. The sealing gasket 72 on the sealing cap 7 can be squeezed into the port of the complementary electrical connector 5, causing the sealing groove 721 to fit against the inner wall of the port of the complementary electrical connector 5. This prevents water accumulation inside the port of the complementary electrical connector 5 due to insufficient compression at the joint seal, thus improving the sealing effect.

[0044] like Figure 16 As shown, the sealing structure of the electrical connector of this utility model includes a flange gasket 6 and a sealing cover 7. The flange gasket 6 is detachably connected to the flange 51 of the complementary electrical connector 5. The sealing cover 7 is connected to the burr 61 extending from one side of the flange gasket 6, and the sealing cover 7 can be flipped to cover the port of the complementary electrical connector 5.

[0045] Specifically, in this embodiment, the sealing of the complementary electrical connector 5 is mainly achieved through the flange gasket 6 and the sealing cover 7. The flange gasket 6 is detachably connected to the flange 51 of the complementary electrical connector 5, used to seal the end of the complementary electrical connector 5 and connect the sealing cover 7. The sealing cover 7 is connected to a flash 61 extending from one side of the flange gasket 6. This connection can be integrally formed or connected via a rotating connector. By bending the flash 61 or rotating the rotating connector, the sealing cover 7 can be flipped over and cover the port of the electrical connector 4, thus achieving sealing of the port of the complementary electrical connector 5 when it is not connected to the electrical connector 4.

[0046] In some embodiments, the flange gasket 6 is bolted to the flange 51.

[0047] Specifically, the flange gasket 6 is detachably connected to the flange 51. In this embodiment, a bolt connection can be used to ensure a tight connection between the flange gasket 6 and the flange 51, thereby improving the sealing effect of the flange gasket 6 and facilitating disassembly and maintenance.

[0048] In some implementation methods, please refer to Figure 17 The sealing cover 7 includes a cover body 71 and a sealing gasket 72; the sealing gasket 72 is disposed on one end face of the sealing cover 7.

[0049] Specifically, the aforementioned sealing cover 7 is used to seal the port of the complementary electrical connector 5 when the complementary electrical connector 5 is not connected to the electrical connector 4. In this embodiment, the sealing cover 7 may include a cover body 71 and a sealing gasket 72, wherein the sealing gasket 72 is disposed on one end face of the sealing cover 7. Specifically, it may be integrally formed on one end face of the cover body 71 to improve the sealing effect of the sealing cover 7.

[0050] In some embodiments, the sealing gasket 72 is a columnar structure, and a plurality of sealing grooves 721 extend circumferentially from the column surface.

[0051] Specifically, the sealing gasket 72, as the main sealing component on the sealing cover 7, can be configured as a columnar structure. The columnar sealing gasket 72 can also extend several sealing protrusions along the circumference of the columnar surface. A sealing groove 721 can be formed between adjacent sealing protrusions. Using multiple sealing grooves 721 as the port seal of the electrical connector 4 can improve the sealing effect.

[0052] In some implementation methods, please refer to Figure 18 and Figure 19 The cross-sectional area of ​​the sealing groove 721 is larger than the cross-sectional area of ​​the port of the complementary electrical connector 5; when the cover 71 is flipped to cover the port of the complementary electrical connector 5, the sealing gasket 72 can be squeezed into the port of the complementary electrical connector 5, so that the sealing groove 721 fits against the inner wall of the port of the complementary electrical connector 5.

[0053] Specifically, in this embodiment, the cross-sectional area of ​​the sealing groove 721 can be set to be larger than the cross-sectional area of ​​the port of the complementary electrical connector 5. Since the cover body 71 and the sealing groove 721 of the entire sealing cover 7 are made of elastic sealing material, when the cover body 71 is flipped to cover the port of the electrical connector 4, the sealing gasket 72 can be squeezed into the port of the complementary electrical connector 5, and the sealing groove 721 can be made to fit against the inner wall of the port of the complementary electrical connector 5. This forms multiple sealing grooves 721 on the inner wall of the port of the complementary electrical connector 5, thereby improving the sealing effect of the sealing cover 7.

[0054] It is worth mentioning that, Figure 18 and Figure 19 The sealing gasket 72 shown is a hollow cylindrical structure, meaning the cross-section of the sealing protrusion and the sealing groove 721 formed between adjacent sealing protrusions is circular. Since the cross-sectional area of ​​the sealing groove 721 is set to be larger than the port cross-sectional area of ​​the complementary electrical connector 5, after the sealing gasket 72 is squeezed into the port of the complementary electrical connector 5, the sealing groove 721 can fit tightly against the inner wall of the port of the complementary electrical connector 5. However, although this shape can improve the sealing effect, the sealing protrusion will undergo large deformation during the opening and closing of the sealing cover 7. Repeated opening and closing will lead to elastic fatigue of the sealing protrusion, thereby affecting the sealing performance. In order to reduce this effect, the cross-sectional shape of the sealing gasket 72 can be set to be the same as the cross-sectional shape of the port of the complementary electrical connector 5, only the area needs to be slightly larger than the cross-sectional area of ​​the port of the complementary electrical connector 5. Thus, without affecting the sealing effect, the service life of the sealing cover 7 is extended.

[0055] In some embodiments, at least one side of the flange gasket 6 is provided with a limiting groove 62; the flange 51 is provided with a limiting protrusion 52 corresponding to the limiting groove 62, which cooperates with the limiting groove 62.

[0056] Specifically, since the flange gasket 6 and the flange 51 are detachably connected by bolts, in order to make the contact between the flange gasket 6 and the flange 51 tighter and less prone to loosening, limiting grooves 62 can be provided on the three sides of the flange gasket 6 where the burr 61 does not extend. Correspondingly, three limiting protrusions 52 are provided at the contact positions between the limiting grooves 62 and the flange 51. When installing the flange gasket 6, the three limiting grooves 62 and the three limiting protrusions 52 can be engaged to limit the flange gasket 6 on the flange 51, thereby making the contact between the flange gasket 6 and the flange 51 tighter and less prone to loosening, and thus improving the sealing effect of the flange gasket 6.

[0057] In some embodiments, a sealing ring 41 is also included; the sealing ring 41 is disposed on the complementary electrical connector 5 at the position where it abuts against the electrical connector 4, such that when the complementary electrical connector 5 and the electrical connector 4 are engaged, a seal is formed at the position where the complementary electrical connector 5 and the electrical connector 4 abut against each other.

[0058] Specifically, the flange gasket 6 and sealing cap 7 described above are sealing structures acting on the complementary electrical connector 5. During the charging process when the electrical connector 4 and the complementary electrical connector 5 are engaged, sealing protection is also required. Therefore, in this embodiment, a sealing ring 41 is also provided. This sealing ring 41 is disposed on the complementary electrical connector 5 at the position where it abuts against the electrical connector 4, enabling a seal to be formed at the port connection between the complementary electrical connector 5 and the electrical connector 4 when they are engaged, thereby achieving protection and sealing of the electrical connector 4 during the charging process.

[0059] Please refer to Figure 20 The present invention also provides an electrical connector assembly, including an electrical connector 4, a complementary electrical connector 5 that is mated with the connector, and a coupling structure as described in any of the above. The first coupling portion of the coupling structure is disposed at the electrical connector 4, which is a first component, and the second coupling portion of the coupling structure is disposed at the complementary electrical connector 5, which is a second component.

[0060] In some embodiments, the electrical connector 4 has a plug end 42 and a first connection end 43, and the complementary electrical connector 5 has a complementary plug end 53 that engages with the plug end 42 and a second connection end 57. Both the first connection end 43 and the second connection end 57 can be connected to a circuit board or wires.

[0061] In some embodiments, the complementary electrical connector 5 further includes a first insulating housing and a second terminal inserted into the first insulating housing. The flange gasket 6 is disposed around the outer periphery of the first insulating housing. The first insulating housing is provided with a partition 54 for dividing the space inside the housing into two parts, forming a mating groove 55 in the direction close to the complementary electrical connector 5 and a mounting groove 56 in the direction away from the complementary electrical connector 5. A sealing ring is provided on the bottom surface of the mating groove 55. A socket is formed on the partition 54 at a position corresponding to the second terminal for insertion. One end of the second terminal is placed in the mating groove to form the mating end 42, and the other end of the second terminal is placed in the mounting groove 56 to form the second connecting end 57.

[0062] Based on the above embodiments, the electrical connector sealing structure of this utility model can achieve sealing of the complementary electrical connector 5 using the sealing cover 7 and the flange gasket 6, and achieve sealing when the complementary electrical connector 5 and the electrical connector 4 are engaged using the sealing ring 42, thereby improving the overall sealing effect of the complementary electrical connector 5; furthermore, through the sealing groove 721, and the setting that the cross-sectional area of ​​the sealing groove 721 is larger than the cross-sectional area of ​​the port of the complementary electrical connector 5, the sealing gasket 72 can be squeezed into the port of the complementary electrical connector 5 when the cover 71 is flipped to cover the port of the complementary electrical connector 5, thereby sealing the groove 721. The groove 721 fits snugly against the inner wall of the port of the complementary electrical connector 5, further improving the sealing effect. It can also be connected to the flange 51 by bolts, which facilitates the disassembly and maintenance of the sealing structure. At the same time, the flange gasket 6 has three limiting grooves 62 on its three sides without the protruding burr 61, and the flange 51 has three corresponding limiting protrusions 52. The three limiting grooves 62 can cooperate with the limiting protrusions 52 to limit the flange gasket 6 on the flange 51, so as to make the contact between the flange gasket 6 and the flange 51 tighter and less prone to loosening, thereby improving the sealing effect of the flange gasket 6.

[0063] In some implementation methods, please refer to Figures 1-15 A connecting structure for connecting the first component and the second component includes:

[0064] The first connecting part includes an elastic frame 11, which is connected to the first component, and a first holding part 12 is provided at the first end of the elastic frame 11.

[0065] The second connecting portion includes a second holding portion 21 that connects to the second component and can engage with the first holding portion 12; and

[0066] The auxiliary component 3 is used to keep the elastic frame 11 in its initial state when the first locking part 12 and the second locking part 21 are engaged, so as to lock the first locking part 12 and the second locking part 21 in a mutually locking state.

[0067] Specifically, when it is necessary to maintain a stable engagement state between the first component and the second component, a locking structure can be used to lock the first component and the second component. In this embodiment, the locking structure mainly includes a first locking portion and a second locking portion. The first locking portion may include an elastic frame 11, which is connected to the first component, and a first holding portion 12 is provided at the first end of the elastic frame 11. The second locking portion may include a second holding portion 21 connected thereto, which can engage with the first holding portion 12 to lock the first component and the second component. In addition, the locking structure may also include an auxiliary member 3, which can keep the elastic frame 11 in its initial state when the first holding portion 12 and the second holding portion 21 are engaged, so as to lock the first holding portion 12 and the second holding portion 21 in a mutually holding state, thereby improving the stability of the first holding portion 12 and the second holding portion 21 during engagement.

[0068] In some implementation methods, please refer to Figures 4-9 The first retaining part 12 is configured to be disposed on the side of the elastic frame 11 and close to the first end of the recessed retaining part; the second retaining part 21 is configured to be a protruding retaining part that is matched with the recessed retaining part.

[0069] The direction in which the first and second connecting parts move towards each other when they are engaged or move away from each other after they are disengaged is defined as the first axial direction. During the process of the first and second connecting parts moving towards each other along the first axial direction, the convex locking part presses against the side of the elastic frame 11 to deform and make room. After the convex locking part moves to the position of the concave locking part, the convex locking part and the concave locking part enter a pre-locked state. The auxiliary member 3 is used to keep the elastic frame 11 in its initial state when the concave locking part is engaged with the convex locking part, so as to lock the first locking part 12 and the second locking part 21 in a mutually locking state.

[0070] Specifically, in this embodiment, the first retaining part 12 is configured as a recessed retaining part located on the side of the elastic frame 11 and near the first end, while the second retaining part 21 is configured as a protruding retaining part that is paired with the recessed retaining part. The recessed retaining part is a concave structure, while the protruding retaining part is a hook structure. The hook engages with the concave structure, thereby allowing the second retaining part 21 to engage with the first retaining part 12. The engagement process involves aligning the convex part with the concave part, moving the first and second engaging parts toward each other along the first axis, causing the concave part to gradually approach the elastic frame 11. As the first and second engaging parts continue to move toward each other, the convex part can deform and move aside by pressing the side of the elastic frame 11. Thus, after the convex part moves to the position of the concave part, it remains in the concave part, completing the pre-locking of the first and second engaging parts. In this pre-locked state, the elastic frame 11 is kept in its initial state by the aforementioned auxiliary member 3, thereby locking the first holding part 12 and the second holding part 21 in a mutually holding state, which can also be called a locked state.

[0071] In some implementation methods, please refer to Figures 10-15 The elastic frame 11 is connected to the first outer wall of the first component. The elastic frame 11 has an inner frame 111 facing the first outer wall, an outer frame 112 connected to the inner frame 111 and located on the side of the inner frame 111 away from the first outer wall, and a passage 113 formed between the inner frame 111 and the outer frame 112. The recessed portion is provided at the first end of the inner frame 111.

[0072] The auxiliary component 3 has a first insert block 31 that is movably inserted into the passage 113 along a first axial direction, a first limiting block 33 formed on the second end of the first insert block 31 away from the first end, a first top block 34 formed on the inner side of the second end of the first insert block 31, and a locking block 35 formed on the inner side of the first end of the first insert block 31; the recessed portion penetrates the inner side frame 111 in both the direction of the outer side frame 112 and the direction of the first outer wall; in the initial state, the locking block 35 protrudes into the recessed portion;

[0073] When the first and second joints are engaged, the first and second joints move toward each other along the first axis. The protruding part presses outward against the inner side of the inner frame 111 to deform it outward. After the protruding part enters the recessed part, it presses the locking block 35 toward the outer frame 112 to increase the tendency of the locking block 35 to disengage from the recessed part. At this time, the locking block 35 has not yet disengaged from the recessed part, and this state is in a pre-locked state.

[0074] When the convex and concave parts are locked in a mutually engaged state, the locking block 35 is pushed toward the first end along the first axis direction. The locking block 35 exits the concave part and moves to the first end face of the inner frame 111. In this state, the elastic frame 11 returns to its initial position inward. The first limiting block 33 of the first insert block 31 abuts against the second end face of the outer frame 112, the first top block 34 abuts against the first outer wall, and the locking block 35 abuts against the first end face of the inner frame 111, so that the elastic frame 11 remains in the initial state to lock the concave and convex parts in a mutually engaged state.

[0075] During unlocking, the auxiliary component 3 is pulled along the first axis towards the second end, so that the first top block 34 is released from its contact with the first outer wall and a pressing space is formed between the first top block 34 and the first outer wall. The locking block 35 moves a corresponding distance towards the second end. Then, the second end of the auxiliary component 3 is pressed inward, so that the second end of the auxiliary component 3 moves towards the pressing space and drives the first end of the auxiliary component 3 to move outward with the elastic frame 11 as the fulcrum. This causes the auxiliary component 3 to drive the first end of the elastic frame 11 to tilt outward, thereby separating the concave part from the convex part. The convex part moves away from the first joint along the first axis, completing the unlocking.

[0076] Specifically, the elastic frame 11 in this solution is connected to the first outer wall of the first component. It may include an inner frame 111 facing the first outer wall and an outer frame 112 connected to the inner frame 111 and located on the side of the inner frame 111 away from the first outer wall. A passage 113 may be formed between the inner frame 111 and the outer frame 112, and a recessed part is provided at the first end of the inner frame 111. The aforementioned auxiliary component 3 may include a first insert block 31, a first limiting block 33, a first top block 34, and a locking block 35. The first insert block 31 is movably inserted into the passageway 113. The first limiting block 33 is located at the second end of the first insert block 31. The first top block 34 is located on the inner side of the second end of the first insert block 31 (i.e., the side facing the first component). The locking block 35 is located on the inner side of the first end of the first insert block 31. In the initial state, the first insert block 31 is inserted into the passageway 113. Since the recessed portion can penetrate the inner frame 111 in both the outer frame 112 and the first outer wall direction, the locking block 35 can protrude into the recessed portion. Therefore, the engagement and unlocking process of the first and second connecting parts can be detailed as follows:

[0077] During the engagement process and in the pre-locked state, when the first engagement part and the second engagement part are engaged, the first engagement part and the second engagement part move towards each other along the first axis direction. The protruding part presses outward against the inner side of the inner frame 111 to deform it outward. After the protruding part enters the recessed part, it presses the locking block 35 towards the outer frame 112. The locking block 35 transmits the outward pressing force to the elastic frame 11 through the first insert 31 to increase the tendency of the locking block 35 to disengage from the recessed part. At this time, the locking block 35 has not yet disengaged from the recessed part, and this state is in the pre-locked state.

[0078] During the locking process and in the locking state, when the convex and concave parts are locked in a mutually engaging state, the locking block 35 is pushed towards the first end along the first axis direction. Since the locking block 35 has increased its tendency to disengage from the concave part due to the compression of the convex part in the pre-locked state, at this time, it is only necessary to push the first insert block 31 along the first end direction, thereby driving the locking block 35 out of the concave part and moving it to the first end face of the inner frame 111. In this state, the elastic frame 11 returns to its initial position inward. The first limiting block 33 of the first insert block 31 abuts against the second end face of the outer frame 112, the first top block 34 abuts against the first outer wall, and the locking block 35 abuts against the first end face of the inner frame 111, so that the elastic frame 11 remains in the initial state to lock the concave and convex parts in a mutually engaging state, i.e., the locked state.

[0079] During the unlocking process, the auxiliary component 3 is pulled along the first axis towards the second end, so that the first top block 34 is released from its contact with the first outer wall and a pressing space is formed between the first top block 34 and the first outer wall. The locking block 35 moves a corresponding distance towards the second end. Then, the second end of the auxiliary component 3 is pressed inward, so that the second end of the auxiliary component 3 moves towards the pressing space and drives the first end of the auxiliary component 3 to move outward with the elastic frame 11 as the fulcrum. This causes the auxiliary component 3 to drive the first end of the elastic frame 11 to tilt outward, thereby separating the concave part from the convex part. Then, the convex part moves away from the first joint along the first axis, thus completing the unlocking process.

[0080] In some embodiments, the auxiliary component 3 further includes a second insert 32 disposed outside the first insert 31, and a recess formed between the first insert 31 and the second insert 32 and accommodated at least partially by the outer frame 112, the opening of the recess facing the first end direction.

[0081] Specifically, to improve the stability between the auxiliary component 3 and the elastic frame 11 after insertion into the passage 113, in this embodiment, the auxiliary component 3 may further include a second insert block 32 disposed outside the first insert block 31, and a recess is formed between the second insert block 32 and the first insert block 31, which can accommodate at least part of the outer frame 112. The opening of the recess faces the first end direction, and the second end direction of the recess is the aforementioned first limiting block 33. The function of the second insert block 32 is not only to improve the stability between the auxiliary component 3 and the elastic frame 11 after insertion into the passage 113, but also, during the unlocking process, the second insert block 32 can provide an inward force to the first end of the elastic frame 11, making it easier for the concave and convex parts to separate from each other. In addition, in the locked state, the recess falls exactly on the top of the elastic frame 11, further enhancing the locking effect of the auxiliary component 3 on the concave and convex parts.

[0082] In some embodiments, a second limiting block 36 is also provided on the outer side of the first insert block 31. The second limiting block 36 is used to limit and cooperate with the first end of the outer frame 112 when the locking block 35 protrudes into the recessed part to prevent the auxiliary member 3 from disengaging from the elastic frame 11 in the direction of the second end.

[0083] Specifically, in this embodiment, a second limiting block 36 may be provided on the outer side of the first insert block 31. When the connecting structure is in a pre-locked state, the locking block 35 protrudes into the recessed part, and at this time the second limiting block 36 can just abut against the first end face of the outer frame 112, so as to cooperate with the first end limiting to prevent the auxiliary part 3 from disengaging from the elastic frame 11 in the direction of the second end.

[0084] In some embodiments, a second top block 13 that cooperates with the first top block 34 is also provided on the first outer wall; when the position of the locking block 35 is adapted to the position of the recessed part, the first top block 34 and the second top block 13 are misaligned and the first top block 34 is closer to the second end direction; when the locking block 35 abuts against the first end face of the inner frame 111, the first top block 34 and the second top block 13 abut against each other to keep the elastic frame 11 in the initial state.

[0085] Specifically, in the aforementioned locked state, the first top block 34 abuts against the first outer wall, thereby preventing the first end of the auxiliary component 3 from being pushed in the locked state, thus causing the elastic frame 11 to deform. During the unlocking process, to deform the elastic frame 11 by pushing the first end of the auxiliary component 3, a pressing space must be formed between the first top block 34 and the first outer wall. In this embodiment, a second top block 13 that can cooperate with the first top block 34 is provided on the first outer wall. When the position of the locking block 35 is adapted to the position of the recessed part, the first top block 34 and the second top block 13 are misaligned, and the first top block 34 is closer to the second end direction. At this time, the misalignment space between the first top block 34 and the second top block 13 can serve as a pressing space. When the locking block 35 abuts against the first end face of the inner frame 111, the first top block 34 and the second top block 13 abut against each other to keep the elastic frame 11 in its initial state.

[0086] In some embodiments, the two sides of the locking block 35 facing the first axis are configured as two guide ramps so that the locking block 35 can smoothly enter or disengage from the recess along the first axis.

[0087] Specifically, since the locking block 35 needs to protrude into the recess before being in the pre-locked state, and during the locking process, the squeezing of the locking block 35 by the protruding part only increases the tendency of the locking block 35 to disengage from the outside of the recess, in order to make the locking block 35 disengage from the outside of the recess and enter the first end face of the recess during the locking process, it is also necessary to configure the two sides of the locking block 35 facing the first axis direction as guide slopes, so that the locking block 35 can smoothly enter or disengage from the recess along the first axis direction.

[0088] In some embodiments, the inner frame 111 is provided with a first clearance opening 114 at a position corresponding to the outer frame 112 for avoiding the locking block 35, and the outer frame 112 is provided with a second clearance opening 115, the second clearance opening 115 being offset from the first clearance opening 114 in a first axial direction; the first clearance opening 114 and the second clearance opening 115 are used to increase the space of the passage 113 so that the locking block 35 can move smoothly within the passage 113.

[0089] In some embodiments, the outer frame 112 is smaller in size along the first axial direction than the corresponding size of the inner frame 111, and the outer frame 112 is closer to the second end direction than the inner frame 111, such that the second clearance opening 115 is formed at both the first end and the second end of the outer frame 112.

[0090] The first end of the first clearance opening 114 is connected to the recessed portion, and the second end of the second clearance opening 115 passes through the second end of the inner frame 111.

[0091] Specifically, since the locking block 35 is a protrusion on the inner side of the first end of the first insertion block 31, in order to facilitate the insertion of the first insertion block 31 into the passage 113, in this embodiment, a first clearance opening 114 for avoiding the locking block 35 can be provided on the inner frame 111 at a position corresponding to the outer frame 112, and a second clearance opening 115 can be provided on the outer frame 112. At the same time, the second clearance opening 115 is offset from the first clearance opening 114 in the first axial direction, thereby increasing the space of the passage 113 so that the locking block 35 can move smoothly in the passage 113.

[0092] Based on the above embodiments, the combination structure of this utility model differs from traditional spring latches or rotational alignment mechanical locks. This solution uses the cooperation of the protruding latch of the second latching part 21 and the concave latch of the first latching part 12 to achieve the combination and locking of the first and second components, avoiding the risks of spring fatigue, latch wear, plastic shell cracking, or damage to the rotational thread structure caused by frequent insertion and removal. Unlike electronic locks, this solution uses the cooperation of the protruding latch of the second latching part 21 and the concave latch of the first latching part 12 to achieve the combination and locking of the first and second components, avoiding locking failure due to power failure and improving the reliability of the combination of the first and second components. Through the locking block 35 on the auxiliary component 3, the protruding latch of the second latching part 21 is locked when it cooperates with the concave latch of the first latching part 12, further improving the stability of the combination of the first and second components. At the same time, this solution also uses the cooperation of the auxiliary component 3 and the elastic frame 11 to unlock the protruding latch and the concave latch. Its structure is simple and easy to maintain.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
