Description

Technical Field

[0001] This invention relates to the field of new energy charging piles and energy storage cabinets, and more specifically, to a double-locking cable connector. Background Technology

[0002] A cable connector, also known as a cable head, is a device used to connect different circuits into a whole, and is widely used in daily life.

[0003] Common cable joint structures are relatively simple, featuring internal clamping sleeves. The cable is secured by the compression of the clamping sleeve during installation using a tightening nut. While the clamping sleeves typically tighten under external pressure to secure the cable, they don't truly contract; rather, they are compressed and stacked together. For smaller cables, the more stacked parts there are, the more interference occurs between the structures, making it harder to achieve a tight connection with the cable and resulting in a poorer secure fit. Furthermore, most fastening structures use a single layer to secure the cable. In actual use, over time, cable vibrations can cause the cable to detach from the joint or become loose, affecting the overall secureness. Additionally, common joint structures are relatively simple, with waterproofing provided only by a single sealing sleeve, offering limited protection. Summary of the Invention

[0016] Beneficial effects:

[0017] Compared with the prior art, the present invention provides a double-locking structure cable connector, which has the following advantages:

[0018] 1. By replacing the original clamping sleeve with a nylon compression ring to secure the cable, the overall length of the nylon compression ring and the clamping sleeve can be directly adjusted according to the cable size through the cooperation of the nylon compression ring, the opening, the gecko tail, and the V-shaped opening. This allows the cable to be adapted to different sizes. Then, by cooperating with the connector and the compression nut, the nylon compression ring is compressed and locks the cable, preventing structural waste caused by compression and accumulation, improving contact effect, and thus enhancing the fastening ability.

[0019] 2. The installation structure is provided by the cooperation of connecting ears, fixing bolts and adjusting rings. The pressure application structure is further provided by the cooperation of locking bolts and locking rings. The cable is subjected to secondary pressure on the upper part of the equipment. The locking effect is improved by the two sets of locking structures. After locking, the fit between the compression nut and the connector can be restricted in reverse, which can improve the cable fastening effect.

[0020] 3. The annular sealing ring provides basic sealing and waterproofing, while the flat gasket and double-layer water ripple protrusion provide additional structural support. Under the pressure applied by the connecting body and the joint body, the sealing and waterproofing effect is improved, thus extending the service life of the equipment. Attached Figure Description

[0030] Please see Figures 1-5 A double-locking cable connector includes a connector body 1, a clamping nut 2 at the upper end of the connector body 1, and a connector body 3 at the lower end. Both the clamping nut 2 and the connector body 3 are threaded into the connector body 1. The connector body 1 and the clamping nut 2 are provided with nylon compression rings 4. The nylon compression rings 4 are made of plastic and have openings 5. The openings 5 ​​have gecko tail pieces 6 at both ends. The gecko tail pieces 6 have V-shaped openings 7. Multiple V-shaped openings 7 are provided. The inner sides of the clamping nut 2 and the connector body 1 are both beveled and cooperate with the nylon compression rings 4.

[0031] The upper end of the clamping nut 2 is fixedly connected with a connecting lug 8, and a fixing bolt 9 is provided on the connecting lug 8. The threads at both ends of the fixing bolt 9 are arranged opposite each other. The connecting lug 8 is provided with an adjusting ring 10 at both ends. The fixing bolt 9 cooperates with the adjusting ring 10. The adjusting ring 10 is provided with a locking bolt 11. The inner side of the adjusting ring 10 is provided with a locking ring 12, and the locking ring 12 cooperates with the locking bolt 11.

[0032] In this embodiment, when installing the cable connector, the nylon compression ring 4 is adjusted according to the cable specifications. If a smaller cable is encountered, the gecko tail piece 6 can be broken off from the V-shaped opening 7 to adjust the overall length and reduce the overall wire diameter. Then, the nylon compression ring 4 is placed in the connector 1, allowing the cable to pass through the nylon compression ring 4 and satisfy the clamping nut 2. During tightening, the clamping nut 2 and the connector 1 will contact the outer end of the nylon compression ring 4 through the internal inclined surface, squeezing and causing the compression ring to contract to tighten the wire, thereby achieving the function of securing the small wire.

[0033] More specifically, the connecting ear 8 provides a support structure, allowing the fixing bolt 9 to engage with the adjusting ring 10. By rotating the adjusting ring 10, it moves towards the center to accommodate the cable and the connector 1. Then, the locking bolt 11 is rotated, engaging with the adjusting ring 10 and moving along the adjusting ring 10. This causes the locking ring 12 to apply pressure inwards, contacting the cable and locking it in place. After locking, the adjusting ring 10 also restricts the engagement between the clamping nut 2 and the connector 1. The two locking structures work together to improve the restraining effect.

[0034] Please see Figure 1 and Figure 4 As one way to improve waterproof performance: an annular sealing ring 13 is provided between the connector body 3 and the connecting body 1, and a flat gasket 14 is provided above the annular sealing ring 13. The flat gasket 14 is provided with double-layer water ripple protrusions 15.

[0035] Specifically, the annular sealing ring 13 provides basic waterproofing between the connector body 3 and the connecting body 1, and then the flat gasket 14 is placed on the annular sealing ring 13. When the connector body 3 and the connecting body 1 are tightened, the connecting body 1 will apply pressure to the flat gasket 14, and the waterproofing will be further improved by the double-layer water ripple protrusion 15.

[0036] Please see Figures 1-5 As a further embodiment of the clamping nut 2: both the clamping nut 2 and the inner side of the connector 1 are provided with a slanted flat washer 16.

[0037] Specifically, by means of the clamping nut 2 and the connector 1, both are in contact with the nylon compression ring 4 through the oblique flat washer 16. Under the support of the nylon compression ring 4, the oblique flat washer 16 is in close contact with the clamping nut 2 and the connector 1, thereby further improving the waterproof capability.

[0038] Please see Figures 1-5 As a further embodiment of the nylon compression ring 4: the nylon compression ring 4 has a notch 17 on the side away from the opening 5.

[0039] Specifically, the notch 17 provides flexibility, making the bending adjustment of the nylon compression ring 4 smoother.

[0040] Please see Figures 1-5 As a further embodiment of the adjustment ring 10: a positioning block 18 is provided on the inner side of the adjustment ring 10, and positioning grooves 19 are provided on both sides of the connecting ear 8, with the positioning block 18 cooperating with the positioning grooves 19.

[0041] Specifically, the movement of the adjusting ring 10 is restricted by the cooperation of the positioning block 18 and the positioning groove 19, making the cooperation between the adjusting ring 10 and the clamping nut 2 more stable.

[0042] Please see Figures 1-5 As a further embodiment of the clamping nut 2: the clamping nut 2 is provided with limiting blocks 20 on both sides, and the adjusting ring 10 is provided with a limiting groove 21 on the outer side, and the limiting blocks 20 cooperate with the limiting groove 21.

[0043] Specifically, the adjusting ring 10 is restricted by the cooperation of the limiting block 20 and the limiting groove 21 to prevent the adjusting ring 10 from coming off the clamping nut 2.

[0044] Please see Figures 1-5 As a further embodiment of the locking ring 12: the outer end of the locking ring 12 is provided with a guide rod 22, which slides in conjunction with the adjusting ring 10.

[0045] Specifically, the guide rod 22 works in conjunction with the adjusting ring 10 to restrict the rotation of the locking ring 12, thereby keeping the locking ring 12 in a stable state.

[0046] Please see Figures 1-5 As a further embodiment of the connector body 3: a flat sealing ring 23 is provided at the lower end of the connector body 3, and a nut 24 is provided below the flat sealing ring 23.

[0047] Specifically, the waterproof capability of the lower connection structure is improved by the cooperation of the flat sealing ring 23 and the nut 24.

[0048] In summary, when the overall equipment is in use (or running):

[0049] When installing the cable connector, adjust the nylon compression ring 4 according to the cable specifications. If encountering a smaller cable, the gecko tail piece 6 can be broken off from the V-shaped opening 7 to adjust the overall length and reduce the overall wire diameter. Then, place the nylon compression ring 4 in the connector 1. The notch 17 provides extension capacity, making the bending adjustment of the nylon compression ring 4 smoother. The nylon compression ring 4 surrounds the cable. During tightening, the clamping nut 2 and connector 1 will contact the outer end of the nylon compression ring 4 through the internal bevel, squeezing and causing the clamping ring to contract to tighten the wire, thereby achieving the function of securing small wires. The connecting ear 8 provides a support structure, allowing the fixing bolt 9 to cooperate with the adjusting ring 10. By rotating the adjusting ring 10, the adjusting ring 10 is brought closer to the center to adapt to the cable and connector 1. The movement of the adjusting ring 10 is restricted by the cooperation of the positioning block 18 and the positioning groove 19, making the cooperation between the adjusting ring 10 and the clamping nut 2 more stable. The adjusting ring 10 is restricted by the cooperation of the limiting block 20 and the limiting groove 21, preventing the adjusting ring 10 from disengaging from the clamping nut 2. Then, the locking bolt 11 is controlled to rotate, so that the locking bolt 11 cooperates with the adjusting ring 10 and moves along the adjusting ring 10, bringing the locking ring 12 inward with pressure. The locking bolt 22 cooperates with the adjusting ring 10 to restrict the rotation of the locking ring 12, keeping the state of the locking ring 12 stable, so that the locking ring 12 contacts the cable and locks the cable. After locking, the adjusting ring 10 also restricts the cooperation between the clamping nut 2 and the connector 1. The cooperation of the two locking structures improves the restriction effect.

[0050] Furthermore, the annular sealing ring 13 provides basic waterproofing between the connector body 3 and the connecting body 1. Then, the flat washer 14 is placed on the annular sealing ring 13. When the connector body 3 and the connecting body 1 are tightened, the connecting body 1 will apply pressure to the flat washer 14. The waterproofing is further improved by the double-layer water ripple protrusion 15. The clamping nut 2 and the connecting body 1 are both in contact with the nylon compression ring 4 through the oblique flat washer 16. Under the support of the nylon compression ring 4, the oblique flat washer 16 is in close contact with the clamping nut 2 and the connecting body 1, further improving the waterproofing. The waterproofing of the lower connection structure is improved by the cooperation of the flat sealing ring 23 and the nut 24.
