[0004] To achieve the above objectives, the present invention provides a solution as follows: a ribbon cable connector, comprising a male connector and a female connector for insertion, and a tail cap fitted over the male and female connectors. Specifically: the male connector includes a male base and a male conductive component, the male conductive component being disposed in the male base; the female connector includes a female base and a female conductive component, the female conductive component being disposed in the female base, at least a portion of the male base being inserted into the female base, and the male conductive component and the female conductive component being electrically connected; the tail cap is fitted over the male and female connectors, and the tail cap corresponds to the connection point of the male and female conductive components.

The outer surface of the female base is provided with a guide groove that mates with the guide rib, and the extension direction of the guide groove is consistent with the assembly direction of the tail cap.

[0007] In some embodiments of this application, the height of the guide ridge is greater than the depth of the guide groove.

[0008] In some embodiments of this application, the tail cover includes a top block and a ring sleeve. The ring sleeve surrounds the male base and the female base, and the ring sleeve and the male base are slidably connected. The top block is disposed at one end of the ring sleeve near the male end, and the top block abuts against the male base in the assembly direction of the tail cover.

[0009] In some embodiments of this application, the male base includes a plug and a first abutment portion, the male conductive component is disposed in the plug, the first abutment portion is connected to the plug, and the female base and the top block are sandwiched with the first abutment portion.

[0010] In some embodiments of this application, the female head further includes a first buckle, which is disposed on the side of the female base near the ring sleeve; the tail cover further includes a second buckle, which is disposed on the side of the ring sleeve near the female head, and the second buckle is engaged with the first buckle.

[0011] In some embodiments of this application, the male base includes a plug and a second abutment portion, the male conductive component is disposed in the plug, and the second abutment portion is connected to the plug; the tail cover also includes a third buckle, the third buckle is disposed on the inner surface of the ring sleeve near the male head, and the third buckle and the top block clamp the second abutment portion.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 3 As shown, Figure 1 This is an overall structural diagram of the ribbon cable connector provided in an embodiment of the present utility model; Figure 2 This is a cross-sectional view of the ribbon cable connector provided in an embodiment of the present utility model, with the cross-section parallel to the extension direction of the ribbon cable 50; Figure 3 This is another cross-sectional view of the ribbon cable connector provided in this embodiment of the present invention, with the cross-section perpendicular to the extension direction of the ribbon cable 50.

[0028] As the circuit load increases, the load capacity and insulation performance of the line connection terminals are optimized accordingly. However, the optimization of the connection terminals, namely the male connector 10 and the female connector 20, is insufficient to compensate for the insulation gaps at their joints. This often becomes the culprit for leakage accidents in the connection structure.

[0029] To solve the above-mentioned technical problems, this utility model discloses a ribbon cable connector, which includes a male head 10 and a female head 20 that are inserted into each other, and a tail cap 30 that is sleeved on the male head 10 and the female head 20.

[0030] Specifically, the male connector 10 includes a male base 11 and a male conductive element 12, with the male conductive element 12 disposed in the male base 11; the female connector 20 includes a female base 21 and a female conductive element 22, with the female conductive element 22 disposed in the female base 21, at least a portion of the male base 11 being inserted into the female base 21, and the male conductive element 12 and the female conductive element 22 being electrically connected; the tail cap 30 is sleeved on the male connector 10 and the female connector 20, and the tail cap 30 corresponds to the connection point of the male conductive element 12 and the female conductive element 22.

[0031] For clarity, the installation method of the ribbon cable connector is explained here with reference to the ribbon cable 50 used in this embodiment: First, connect the ribbon cable 50 to the female connector 20, so that the ribbon cable 50 is electrically connected to the female conductive component 22; then, pass another set of ribbon cables 50 through the tail cover 30 and connect them to the male connector 10, so that this set of ribbon cables 50 is electrically connected to the common conductive component; then, insert the male base 11 into the female base 21, so that the male conductive component 12 is electrically connected to the female conductive component 22; finally, slide the tail cover 30 along the insertion direction of the male base 11, so that the tail cover 30 is sleeved on the male connector 10 and the female connector 20, and corresponds to the connection point of the male conductive component 12 and the female conductive component 22.

[0032] The male base 11 is partially inserted into the female base 21. The male conductive component 12, located in the male base 11, is electrically connected to the female conductive component 22, located in the female base 21. The joint between the male conductive component 12 and the female conductive component 22 is exposed relative to both the male base 11 and the female base 21. Moreover, this part is one of the areas with the highest resistance in the entire circuit, making the joint between the male conductive component 12 and the female conductive component 22 a high-risk area for leakage accidents. The tail cover 30 encloses the joint between the male conductive component 12 and the female conductive component 22, compensating for the deficiencies in the shielding structure of the male base 11 and the female base 21.

[0033] It should be noted that in most ribbon cable connectors, the connection point between the male conductive component 12 and the female conductive component 22 is close to the seam between the male connector 10 and the female connector 20 in the extension direction of the ribbon cable 50. The tail cap 30 provided at the connection point between the male conductive component 12 and the female conductive component 22 can simultaneously cover the seam between the male connector 10 and the female connector 20. For male base 11 and female base 21 structures where the seam cannot be covered, appropriately extending the length of the tail cap 30 in the insertion direction of the male base 11 to cover the seam between the male base 11 and the female base 21 can effectively improve the insulation effect.

[0034] In some embodiments of this application, the mother base 21 includes a base body 211, a protective layer 212 and a plurality of spacers 213. The mother conductive component 22 is disposed in the base body 211, and the plurality of spacers 213 are disposed between the base body 211 and the protective layer 212. The base body 211 and the protective layer 212 are spaced apart, and the protective layer 212 is connected to the tail cap 30.

[0035] The base 211 and the protective layer 212 are spaced apart, forming an insulating cavity. The cavity is filled with air, which is almost non-conductive as a dielectric. This insulating cavity surrounding the main conductive component 22 effectively prevents current from flowing from the main conductive component 22 to the outside, ensuring that the current is transmitted along a preset path. The spacer 213 allows the protective layer 212 to maintain a stable relative position with the base 211, thus maintaining the stability of the insulating cavity's shape.

[0036] Please refer to the above as well. Figure 4 , Figure 4 for Figure 3 A magnified view of a portion of region A in the middle.

[0037] In some embodiments of this application, the tail cover 30 includes a ring 31 and a guide rib 32. The ring 31 is surrounded by a male base 11 and a female base 21. The guide rib 32 is disposed on the inner surface of the ring 31 near the female base 21. The outer surface of the female base 21 is provided with a guide groove 214 that cooperates with the guide rib 32. The extending direction of the guide groove 214 is consistent with the assembly direction of the tail cover 30.

[0038] The guide groove 214 and guide rib 32 make the assembly and positioning of the tail cover 30 easier. Furthermore, the guide rib 32, embedded within the guide groove 214, also helps to position the tail cover 30. In addition, the asymmetrical arrangement of the guide grooves 214 on both sides of the mother base 21—specifically, changing the position, number, and length of the guide grooves 214 on both sides and correspondingly configuring the guide rib 32—can prevent incorrect installation and avoid the tail cover 30 being installed backwards.

[0039] Furthermore, the height of the guide ridge 32 is greater than the depth of the guide groove 214.

[0040] The height of the guide ridge 32 is greater than the depth of the guide groove 214, which creates a gap between the inner wall of the tail cover 30 and the outer wall of the mother base 21. Similar to the insulating cavity mentioned above, the air in the gap can play an insulating role, enhancing the protective effect of the tail cover 30.

[0041] It is important to note that leakage in ribbon cable connectors mainly stems from two causes. First, the high resistance at the connection point between the male conductive component 12 and the female conductive component 22, along with inductance caused by connection fluctuations, can potentially break down the insulation between the male base 11 and the female base 21, leading to nearby equipment becoming energized. Second, the uneven distribution of the electric field generated near the connection point between the male conductive component 12 and the female conductive component 22 along the gap between the male base 11 and the female base 21 results in corona discharge due to a loose connection between the male base 11 and the female base 21. The technical solution provided in this embodiment, which allows a gap between the tail cap 30 and the female base 21, is more suitable for the former. For the latter, tightly fitting the inner wall of the tail cap 30 to the outer wall of the female base 21 and covering the seam between the male base 11 and the female base 21 can produce better insulation.

[0042] In some embodiments of this application, the tail cover 30 includes a top block 33 and a ring 31. The ring 31 is arranged around the male base 11 and the female base 21. The ring 31 and the male base 11 are slidably connected. The top block 33 is disposed at one end of the ring 31 near the male head 10. The top block 33 abuts against the male base 11 in the assembly direction of the tail cover 30.

[0043] The top block 33 provides a positioning method for the assembly of the tail cover 30. Under the premise that the length of the top block 33 is configured according to the structure of the male head 10 and the female head 20, the tail cover 30 can be positioned by simply pushing the top block 33 into contact with the male base 11, which facilitates assembly and improves installation efficiency.

[0044] It should be noted that in this embodiment, the top block 33 abuts against the male base 11. In fact, the top block 33 can also abut against the female base 21. When the top block 33 abuts against the male base 11, the male base 11 is inserted into the female base 21. That is, there is no difference in the assembly method between the two abutment methods. One hand holds the female head 20 and the other hand holds the tail cover 30 and pushes it in. The only difference is whether the tail cover 30 abuts directly against the female base 21 or indirectly against the female base 21 through the male base 11.

[0045] Furthermore, the male base 11 includes a plug 111 and a first contact portion 112. The male conductive component 12 is disposed in the plug 111, and the first contact portion 112 is connected to the plug 111. The female base 21 and the top block 33 clamp the first contact portion 112.

[0046] The first contact part 112 is positioned by the female base 21 and the top block 33, and the plug 111 is connected to the first contact part 112, thereby realizing the positioning of the relative positions of the male conductive component 12 and the female conductive component 22.

[0047] Please refer to the above as well. Figure 5 , Figure 5 for Figure 2 A magnified view of a portion of region B in the middle.

[0048] Optionally, the female head 20 also includes a first buckle 23, which is disposed on the side of the female base 21 near the ring sleeve 31; the tail cover 30 also includes a second buckle 34, which is disposed on the side of the ring sleeve 31 near the female head 20, and the second buckle 34 is engaged with the first buckle 23.

[0049] The second buckle 34 and the top block 33 are both disposed on the inner wall of the ring sleeve 31. The second buckle 34 is engaged with the first buckle 23 from the side away from the male base 11. The top block 33 abuts against the male base 11 from the side away from the female base 21. The top block 33 and the second buckle 34 clamp the male base 11 and the female base 21 to prevent the male base 11 from separating from the female base 21, thereby ensuring a stable connection between the male conductive component 12 and the female conductive component 22.

[0050] Please refer to the above as well. Figure 6 , Figure 6 for Figure 2 A magnified view of a portion of region C.

[0051] Optionally, the male base 11 includes a plug 111 and a second abutment 113, with the male conductive element 12 disposed in the plug 111 and the second abutment 113 connected to the plug 111; the tail cover 30 also includes a third buckle 35, which is disposed on the inner surface of the ring 31 near the male head 10, and the third buckle 35 and the top block 33 clamp the second abutment 113.

[0052] The third buckle 35 and the top block 33 clamp the second abutment part 113 to achieve the positioning of the male base 11 and the ring 31.

[0053] It should be noted that the above embodiments do not conflict with each other. That is, in a preferred embodiment, the ring 31 may be provided with a second buckle 34, a third buckle 35 and a top block 33 at the same time, so that the male head 10, the female head 20 and the tail cover 30 are stably connected.

[0054] In some embodiments of this application, the tail cover 30 includes a ring 31 and a tail plate 36. The ring 31 is wrapped around the male base 11 and the female base 21. The tail plate 36 covers the end of the ring 31 away from the female head 20. The tail plate 36 has a wire hole 361 for the cable to pass through.

[0055] The tail plate 36 covers the end of the ring 31 away from the female connector 20, making the seal of the tail plate 30 at the connection between the male connector 10 and the female connector 20 more complete and preventing the electric field from leaking out from the gap between the male connector 10 and the ring 31. The wire hole 361 is designed not only to allow the ribbon cable 50 to pass through, but also to position the ribbon cable 50, preventing the ribbon cable 50 from hanging to one side and causing poor connection between the ribbon cable 50 and the male conductive component 12.

[0056] In some embodiments of this application, the ribbon cable connector further includes a heat shrink sleeve 40, which is sleeved on the outside of the female base 21, and the end of the female base 21 away from the male base 11 is wrapped by the heat shrink sleeve 40.

[0057] After assembly, the heat-shrink sleeve 40 is heated and shrunk, allowing it to fit well against the female base 21, especially wrapping around the end of the female base 21 furthest from the male base 11, thus positioning the female base 21 and the ribbon cable 50. It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationships and movement of components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0058] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0059] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the design concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
