Description

Technical Field

[0001] The invention relates to the technical field of conductive connection devices, and in particular to a high current-carrying connector terminal connection structure. Background Art

[0002] High current-carrying terminal connector terminal connection structure is usually used to connect cables (wires) in high current electrical equipment or power supply systems. High current-carrying terminal connector terminal connection structure usually has the characteristics of high current carrying capacity, excellent conductivity, high temperature resistance and reliable connection method. These characteristics make the high current-carrying terminal connector terminal connection structure an indispensable part of power systems and industrial equipment, ensuring the safe operation and reliability of the equipment.

[0003] In order to provide better current-carrying capacity, the existing high-current connector terminal connection structure usually adopts a circular plug-in terminal connection structure to provide a larger contact area. However, this type of terminal connection structure achieves tight crimping through the deformation of the terminal itself, and a long friction path will appear during the plugging process. Although the contact surface of the terminal connection structure is usually sprayed with wear-resistant materials to prevent wear, wear will still occur after too many plug-ins, resulting in poor circuit contact, generation of large amounts of heat and other dangerous situations, seriously affecting the service life. Summary of the invention

[0004] During maintenance and regular inspection of power equipment, staff need to disconnect the terminal connector for inspection and then reconnect the terminal connector after the inspection. The regular inspection cycle is usually once a month or two weeks. This will cause the terminal connection structure to wear due to excessive plugging and unplugging.

[0047] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0048] like Figures 1 to 11 As shown, a high current-carrying connector terminal connection structure includes a male conductive terminal 100, a female conductive terminal 200 and an adjustment component 300, one end of the female conductive terminal 200 has a star-shaped polygonal structure 210, the star-shaped polygonal structure 210 is elastic, one end of the star-shaped polygonal structure 210 is open, and the diameter of the circumscribed circle of the star-shaped polygonal structure 210 can be changed within a preset range. The adjustment component 300 is arranged between the male conductive terminal 100 and the female conductive terminal 200, and the adjustment component 300 is used to adjust the circumference of the star-shaped polygonal structure 210. When the male conductive terminal 100 moves relative to the star-shaped polygonal structure 210 along the axis of the male conductive terminal 100, the adjusting component 300 enlarges the diameter of the circumscribed circle of the star-shaped polygonal structure 210 so that the star-shaped polygonal structure 210 and the male conductive terminal 100 do not contact each other. When the male conductive terminal 100 moves to a preset position inside the star-shaped polygonal structure 210, the adjusting component 300 reduces the diameter of the circumscribed circle of the star-shaped polygonal structure 210 so that the star-shaped polygonal structure 210 and the male conductive terminal 100 fit each other.

[0049] When connecting the male conductive terminal 100 and the female conductive terminal 200, the staff holds the male conductive terminal 100 and the female conductive terminal 200 in both hands, and then inserts the male conductive terminal 100 into the star-shaped polygonal structure 210. During the sliding process of the male conductive terminal 100 into the star-shaped polygonal structure 210, the adjustment component 300 expands the diameter of the circumscribed circle of the star-shaped polygonal structure 210 so that the star-shaped polygonal structure 210 and the male conductive terminal 100 do not contact each other. Therefore, during the connection process of the male conductive terminal 100 and the female conductive terminal 200, the male conductive terminal 100 There is no friction path between the male conductive terminal 100 and the star-shaped polygonal structure 210, so wear between the male conductive terminal 100 and the star-shaped polygonal structure 210 can be effectively avoided. When the male conductive terminal 100 moves to a preset position inside the star-shaped polygonal structure 210, the adjustment component 300 reduces the diameter of the circumscribed circle of the star-shaped polygonal structure 210 so that the star-shaped polygonal structure 210 and the male conductive terminal 100 fit each other. At this time, good circuit contact can be ensured to avoid safety failures due to poor circuit contact. Finally, the male conductive terminal 100 and the female conductive terminal 200 can be connected together. When it is necessary to disconnect the male conductive terminal 100 and the female conductive terminal 200, the staff also holds the male conductive terminal 100 and the female conductive terminal 200 with both hands respectively, and then moves the male conductive terminal 100 out from the inside of the female conductive terminal 200. During this process, the adjustment component 300 expands the diameter of the circumscribed circle of the star-shaped polygonal structure 210 so that the star-shaped polygonal structure 210 and the male conductive terminal 100 do not contact each other. Therefore, there is no friction path when the male conductive terminal 100 is pulled out from the inside of the star-shaped polygonal structure 210, thereby effectively avoiding wear between the male conductive terminal 100 and the star-shaped polygonal structure 210.

[0050] It should be noted that the high current carrying connector terminal connection structure further includes a first wire connector 440, the first wire connector 440 is electrically connected to the male conductive terminal 100, and the end of the first wire connector 440 away from the male conductive terminal 100 is connected to the first wire. The high current carrying connector terminal connection structure further includes a second wire connector 450, the second wire connector 450 is electrically connected to the star-shaped polygonal structure 210, and the end of the second wire connector 450 away from the star-shaped polygonal structure 210 is connected to the second wire.

[0051] In this embodiment, if Figure 2 and Fig.10 As shown, the outer peripheral surface of the male conductive terminal 100 is a plum blossom shape, and the star-shaped polygonal structure 210 is a matching plum blossom shape.

[0052] It can be understood that the star-shaped polygonal structure 210 is in the shape of a plum blossom, which easily forms stress concentration areas at the sharp corners of the polygonal connection structure. When the stress concentration areas are subjected to external forces, these areas are more likely to deform than smooth circular surfaces, which is conducive to allowing the diameter of the star-shaped polygonal structure 210 to vary within a preset range.

[0053] In this embodiment, if Figure 7 and Figure 8 As shown, a plurality of through grooves 211 are formed at equal intervals in the circumferential direction at the non-open end of the star-shaped polygonal structure 210 .

[0054] It can be understood that a number of through grooves 211 are circumferentially evenly spaced at the non-open end of the star-shaped polygonal structure 210, thereby creating multiple local weak points in the circumference of the star-shaped polygonal structure 210. Compared with the connecting ring without grooves, the tensile strength and stiffness of these weak points will be reduced, which makes it easier to expand or reduce the diameter of the star-shaped polygonal structure 210.

[0055] In this embodiment, if Figure 3 and Figure 4 As shown, the adjustment component 300 includes a female wear-resistant strip 310 and a male wear-resistant strip 320. There are multiple female wear-resistant strips 310, and the multiple female wear-resistant strips 310 are embedded on the outer peripheral surface of the male conductive terminal 100 at equal intervals in the circumferential direction. A plurality of slots 311 are opened on the outer side of the female wear-resistant strip 310, and the plurality of slots 311 are arranged at non-equal intervals along the length direction of the female wear-resistant strip 310. The slots 311 are isosceles trapezoids, and the side sides of the slots 311 along the length direction of the female wear-resistant strip 310 are the hypotenuses of the isosceles trapezoid. There are multiple male wear-resistant strips 320, and the multiple male wear-resistant strips 320 are arranged on the inner peripheral surface of the female conductive terminal 200 at equal intervals in the circumferential direction. And multiple male wear-resistant strips 320 correspond one-to-one with multiple female wear-resistant strips 310, and multiple blocks 322 are arranged on the outer surface of the male wear-resistant strip 320, and the multiple blocks 322 correspond one-to-one with the multiple slots 311, and the shape of the blocks 322 is adapted to the shape of the slots 311, and multiple guide columns 321 are arranged on the inner side surface of the male wear-resistant strip 320, and the multiple guide columns 321 correspond to the positions of the multiple blocks 322, and one end of the guide column 321 away from the male wear-resistant strip 320 passes through the outside of the star-shaped polygonal structure 210, and a connecting rod 330 is arranged between the multiple guide columns 321 corresponding to the male wear-resistant strip 320.

[0056] When the male conductive terminal 100 moves toward the inside of the star-shaped polygonal structure 210, after the inclined surface of the clamping block 322 contacts the outer side surface of the female wear-resistant strip 310, as the male conductive terminal 100 continues to move toward the inside of the star-shaped polygonal structure 210 along its axis, under the guiding action of the inclined surface of the clamping block 322, the distance between the opposite surfaces of the female wear-resistant strip 310 and the male wear-resistant strip 320 gradually increases, and the clamping block 322 pushes the star-shaped polygonal structure 210 outward through the male wear-resistant strip 320, so that the diameter of the circumscribed circle of the star-shaped polygonal structure 210 is gradually expanded. When the outer side surface of the female wear-resistant strip 310 contacts the end of the block 322, the distance between the outer circumference of the male conductive terminal 100 and the inner circumference of the star-shaped polygonal structure 210 gradually increases to a maximum value, and the diameter of the circumscribed circle of the star-shaped polygonal structure 210 is expanded to a maximum diameter. At this time, the inner circumference of the star-shaped polygonal structure 210 and the outer circumference of the male conductive terminal 100 do not contact each other, so in the process of the male conductive terminal 100 sliding into the star-shaped polygonal structure 210, the inner circumference of the star-shaped polygonal structure 210 and the outer circumference of the male conductive terminal 100 are not in contact with each other. There will be no friction path between the outer peripheral surfaces, and there will be no excessive wear due to sliding friction. As the male conductive terminal 100 continues to move into the star-shaped polygonal structure 210, the male wear-resistant strip 320 drives the block 322 to move to the position where the block 322 corresponds to the slot 311. Since the plurality of slots 311 are arranged at non-equidistant intervals along the length direction of the female wear-resistant strip 310, the diameter of the star-shaped polygonal structure 210 will be reduced only when all the slots 311 correspond to all the blocks 322 one by one. When the polygonal structure 210 is in the preset position, all the card blocks 322 correspond to all the card slots 311 one by one. At this time, the card blocks 322 no longer squeeze the star-shaped polygonal structure 210 outward. The diameter of the star-shaped polygonal structure 210 gradually shrinks under the action of its own elastic force, so all the card blocks 322 move to the corresponding card slots 311. At this time, the outer circumference of the male conductive terminal 100 and the inner circumference of the star-shaped polygonal structure 210 fit each other, thereby ensuring good circuit contact and avoiding safety failures due to poor circuit contact.

[0057] It should also be noted that if Figure 3 As shown, the connecting rod 330 is provided to ensure the consistency of movement of the plurality of guide posts 321 , thereby preventing the male conductive terminal 100 from getting stuck when moving toward the inside of the star-shaped polygonal structure 210 .

[0058] In this embodiment, if Figure 3As shown, the high current-carrying connector terminal connection structure also includes a first shell 410 and a wear-resistant ring 420. The wear-resistant ring 420 is sleeved in the first shell 410, and the guide column 321 is slidably connected to the wear-resistant ring 420 at one end passing through the star-shaped polygonal structure 210. Specifically, a straight groove 421 is opened on the inner side surface of the wear-resistant ring 420, and the guide column 321 is slidably connected to the wear-resistant ring 420 through the straight groove 421. There is a preset distance between the inner circumference of the wear-resistant ring 420 and the outer circumference of the star-shaped polygonal structure 210.

[0059] When the end of the block 322 contacts the outer side surface of the female wear-resistant strip 310, the star-shaped polygonal structure 210 is squeezed outward by the male wear-resistant strip 320 and the block 322 and its diameter gradually increases. Then, the male wear-resistant strip 320 drives the guide column 321 to move toward the inside of the straight slide groove 421 under the guidance of the straight slide groove 421. Therefore, the straight slide groove 421 is provided to guide the movement of the guide column 321 to prevent the guide column 321 from tilting and causing the outer circumference of the male conductive terminal 100 and the inner circumference of the star-shaped polygonal structure 210 to have inconsistent spacing.

[0060] In this embodiment, if Figure 3 As shown, the high current-carrying connector terminal connection structure further includes a threaded ring 430 , which is threadedly connected to the first housing 410 , and the threaded ring 430 is coaxially abutted against the wear-resistant ring 420 .

[0061] The threaded ring 430 is provided to fix the wear-resistant ring 420 so that when the first housing 410 moves, the first housing 410 and the wear-resistant ring 420 do not move relative to each other, thereby ensuring the connection stability of the high current-carrying connector terminal connection structure.

[0062] In this embodiment, if Figure 3 As shown, a connecting groove 212 is provided on the star-shaped polygonal structure 210 , and the guide column 321 can move within a preset range along the axis of the star-shaped polygonal structure 210 relative to the connecting groove 212 . Specifically, the width of the connecting groove 212 is greater than the width of the guide column 321 .

[0063] When the staff pulls out the male conductive terminal 100 from the star-shaped polygonal structure 210, the staff holds the first shell 410 by hand, so that the first shell 410 and the male conductive terminal 100 move away from each other. At this time, the first shell 410 drives the wear-resistant ring 420 to move synchronously, and the wear-resistant ring 420 drives the guide column 321 to move synchronously through the straight slide groove 421. At this time, the end of the block 322 gradually slides outward from the bottom of the slot 311, and the male wear-resistant strip 320 drives the star-shaped polygonal structure 210 to gradually move away from the male conductive terminal 100. Since the width of the connecting groove 212 is greater than the width of the guide column 321, the star-shaped polygonal structure 210 and the male conductive terminal 100 are connected. The electrical terminals 100 will only move away from each other but will not slide relative to each other. When the end of the block 322 moves to the notch position of the slot 311, the side of the guide post 321 just fits with the side of the connecting slot 212, and the distance between the male conductive terminal 100 and the star-shaped polygonal structure 210 increases to the maximum distance. Then, as the wear-resistant ring 420 drives the guide post 321 to continue to move synchronously through the straight sliding slot 421, the male conductive terminal 100 and the star-shaped polygonal structure 210 will not contact each other, thereby avoiding wear between the male conductive terminal 100 and the star-shaped polygonal structure 210 during the sliding process of the guide post 321 relative to the connecting slot 212.

[0064] In this embodiment, if Figure 4 As shown, the high current-carrying connector terminal connection structure further includes a second housing 460 , in which the second wire connector 450 is disposed. The second housing 460 is provided to protect the second wire connector 450 .

[0065] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
