Description

Technical Field

[0001] This utility model relates to the field of quick connectors, and in particular to a high-reliability anti-loosening quick connector for new energy battery packs. Background Technology

[0002] New energy vehicles typically use new energy battery packs as their energy source. When the new energy battery pack provides power to the new energy vehicle, it usually needs to be installed on the power supply interface of the new energy battery pack using a corresponding connector so that it can be connected to the port connector of the power supply wire to complete the power supply.

[0003] Existing new energy battery pack connectors typically use plug-in connectors to achieve connection through plugging and unplugging. However, frequent plugging and unplugging can cause wear on the contact parts, and the lack of a reliable locking mechanism makes them prone to falling off under vibration.

[0004] Therefore, in view of the fact that the existing new energy battery pack connectors are prone to falling off under vibration, a highly reliable anti-loosening quick connector for new energy battery packs can be designed. By adopting a corresponding locking mechanism on the connector, it can be quickly connected while effectively preventing it from falling off and loosening, thus solving the above problems. Utility Model Content

[0005] To overcome the problems of existing new energy battery pack connectors, which typically use plug-in connectors and connect by plugging and unplugging, frequent plugging and unplugging can cause wear on the contact parts, and the lack of a reliable locking mechanism makes them prone to falling off in vibration environments.

[0006] The technical solution of this utility model is as follows: a high-reliability anti-loosening quick connector for new energy battery packs, comprising an insertion end, a fixed end, a connecting anti-loosening sleeve, a bucket-shaped limiting sleeve, an insulating sleeve, and a connector; the rear end of the insertion end is provided with a fixed end for fixing to the power supply interface of the new energy battery pack; an anti-loosening groove for preventing the female cable connector from detaching is provided between the insertion end and the fixed end; a connecting anti-loosening sleeve for preventing the female cable connector from detaching is sleeved on the outside of the insertion end near the anti-loosening groove; a bucket-shaped limiting sleeve for cooperating with the connecting anti-loosening sleeve is sleeved on the outside of the bucket-shaped limiting sleeve away from the anti-loosening groove; and a connector for connecting to the power supply interface of the new energy battery pack is provided on the fixed end away from the anti-loosening groove.

[0007] Preferably, this application combines an insertion end, a fixed end, a connecting anti-disengagement sleeve, a bucket-shaped limiting sleeve, and a connector, so that when powering on, it can be connected to the power supply interface of the new energy battery pack through the connector. Then, the port connector of the power cord is aligned with the insertion end, and the port connector is pressed down so that the insertion end is pushed into the interior of the port connector. The core of the power cord is inserted from the center of the insertion end, and the outer shell of the port connector expands along the connecting anti-disengagement sleeve. The retaining ring at the edge of the outer shell engages with the anti-loosening groove, and the bucket-shaped limiting sleeve works with the connecting anti-disengagement sleeve to fix the retaining ring.

[0008] Preferably, a first quick-connect chamfer is provided at the outer edge of the insertion end away from the anti-loosening slot, an access chamfer is provided at the inner wall edge of the insertion end away from the anti-loosening slot, and a second quick-connect chamfer is provided at the outer end of the connecting anti-loosening sleeve away from the anti-loosening slot to match the first quick-connect chamfer.

[0009] Preferably, a snap-fit ​​embedded ring groove is provided on the inner wall edge of the insertion end near the anti-loosening slot, and a threaded groove is provided on the inner wall of the snap-fit ​​embedded ring groove.

[0010] Preferably, a retaining connector is provided at the inner wall edge of the fixed end near the anti-loosening groove, one end of the retaining connector extends into the inner ring groove of the retaining connector, and the outer end of the retaining connector is fitted with a threaded sleeve corresponding to the threaded groove.

[0012] Preferably, the outer end of the insulating sleeve is provided with an anti-slip rubber strip, and multiple sets of anti-slip rubber strips are provided, which are arranged around the outer end of the insulating sleeve.

[0013] Preferably, the outer end of the connector is provided with a positioning groove, and there are four sets of positioning grooves arranged around the outer end of the connector.

[0014] The beneficial effects of this utility model are as follows: Compared with traditional new energy battery pack connectors, which are prone to falling off under vibration, this application uses a uniquely designed anti-detachment sleeve and a bucket-shaped limiting sleeve, along with an anti-loosening groove, to firmly fix the port connector to the insertion end, effectively preventing accidental detachment due to vibration or other external forces. The design of the first quick-connect chamfer, the second quick-connect chamfer, and the access chamfer allows the port connector to quickly and accurately align with the insertion end, simplifying the installation process and improving work efficiency. The insulating sleeve is located in the insulating recess of the bucket-shaped limiting sleeve and is equipped with an anti-slip rubber strip, which not only provides necessary electrical isolation but also increases the feel when holding it, making it easier to operate.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a high-reliability anti-loosening quick connector for new energy battery packs, comprising an insertion end 1, a fixed end 2, a connecting anti-loosening sleeve 3, a funnel-shaped limiting sleeve 5, an insulating sleeve 6, and a connector 7; the rear end of the insertion end 1 is provided with a fixed end 2 for fixing to the power supply interface of the new energy battery pack; an anti-loosening groove 4 is provided between the insertion end 1 and the fixed end 2 to prevent the female cable connector from detaching; the end of the insertion end 1 near the anti-loosening groove 4 is provided with a connecting anti-loosening sleeve 3 for preventing the female cable connector from detaching; the end of the fixed end 2 near the anti-loosening groove 4 is provided with a funnel-shaped limiting sleeve 5 for cooperating with the connecting anti-loosening sleeve 3; the outer end of the funnel-shaped limiting sleeve 5 away from the anti-loosening groove 4 is provided with an insulating sleeve 6 for insulation; and the end of the fixed end 2 away from the anti-loosening groove 4 is provided with a connector 7 for connecting to the power supply interface of the new energy battery pack.

[0023] Please see Figures 2-3In this embodiment, a first quick-connect chamfer 8 is provided at the outer edge of the insertion end 1 away from the anti-loosening slot 4, and an access chamfer 9 is provided at the inner wall edge of the insertion end 1 away from the anti-loosening slot 4. A second quick-connect chamfer 10 is provided at the outer end of the connecting anti-loosening sleeve 3 away from the anti-loosening slot 4 to match the first quick-connect chamfer 8. By combining the first quick-connect chamfer 8, the second quick-connect chamfer 10 and the access chamfer 9, when the connecting wire is connected to the new energy battery pack, the port connector of the connecting wire can quickly and accurately align with the insertion end 1, simplifying the power supply connection process and improving work efficiency. A snap-fit ​​embedded ring groove 11 is provided at the inner wall edge of the insertion end 1 near the anti-loosening slot 4, and a threaded groove 12 is provided on the inner wall of the snap-fit ​​embedded ring groove 11.

[0024] Please see Figures 2-3 In this embodiment, a snap-fit ​​connector 13 is provided on the inner wall edge of the fixed end 2 near the anti-loosening slot 4. One end of the snap-fit ​​connector 13 extends into the interior of the snap-fit ​​embedded ring groove 11. The outer end of the snap-fit ​​connector 13 is fitted with a threaded sleeve 14 corresponding to the threaded groove 12. By combining the snap-fit ​​connector 13 with the snap-fit ​​embedded ring groove 11, during installation, the operator can rotate and twist the snap-fit ​​connector 13 along the threaded groove 12 of the snap-fit ​​embedded ring groove 11 through the threaded sleeve 14, thereby connecting and combining the fixed end 2 with the insertion end 1. The outer end of the bucket-shaped limiting sleeve 5 away from the anti-loosening slot 4 is provided with an insulating embedded groove 15. The insulating sleeve 6 is located inside the insulating embedded groove 15. By combining the insulating embedded groove 15 with the insulating sleeve 6, the insulating sleeve 6 inside the insulating embedded groove 15 can effectively provide electrical insulation protection for the operator when disassembling the quick connector.

[0025] Please see Figures 3-5 In this embodiment, the outer end of the insulating sleeve 6 is provided with an anti-slip rubber strip 17. Multiple sets of anti-slip rubber strips 17 are arranged around the outer end of the insulating sleeve 6. The outer end of the connector 7 is provided with a positioning groove 16. Four sets of positioning grooves 16 are arranged around the outer end of the connector 7. By combining multiple sets of anti-slip rubber strips 17, it is convenient for workers to hold and operate during maintenance. By combining multiple sets of positioning grooves 16, the connector 7 can be guided and positioned when inserted into the power supply interface of the new energy battery pack.

[0026] When working, the staff first connects to the power supply interface of the new energy battery pack through connector 7.

[0027] When connecting the power supply, the port connector of the power cord is aligned with the insertion end 1 and pressed down so that the insertion end 1 can smoothly enter the port connector. During this process, the power cord core passes through the center of the insertion end 1, while the outer shell of the port connector expands along the connection anti-disengagement sleeve 3.

[0028] As the port connector continues to advance, the retaining ring at the edge of its outer shell will engage with the anti-loosening groove 4 to achieve initial locking. At the same time, the bucket-shaped limiting sleeve 5 and the connecting anti-loosening sleeve 3 work together to further reinforce the position of the retaining ring, ensuring that it will not easily loosen or fall off.

[0029] The insulating sleeve 6 provides an additional layer of electrical isolation, avoiding the risk of potential short circuits. The anti-slip rubber strip 17 increases friction, making it easier for users to operate, while the positioning groove 16 helps to achieve precise docking and reduces the possibility of misoperation.

[0030] Through the above steps, this application combines the insertion end 1, the fixed end 2, the connecting anti-detachment sleeve 3, the bucket-shaped limiting sleeve 5, and the connector 7. During power connection, the connector 7 can be used to connect to the power supply interface of the new energy battery pack. Then, the port connector of the power cord is aligned with the insertion end 1, and the port connector is pressed down, causing the insertion end 1 to be pushed into the interior of the port connector. The core of the power cord is inserted from the center of the insertion end 1, while the outer shell of the port connector expands along the connecting anti-detachment sleeve 3. The retaining ring at the edge of the outer shell engages with the anti-loosening groove 4. The bucket-shaped limiting sleeve 5, in conjunction with the connecting anti-detachment sleeve 3, secures the retaining ring. Through the uniquely designed connecting anti-detachment sleeve 3 and bucket-shaped limiting sleeve 5, combined with the anti-loosening groove 4, the port connector can be firmly fixed to the insertion end 1, effectively preventing accidental detachment due to vibration or other external forces.
