[0002] In the fields of power transmission and signal connection, connectors, as key components, directly determine the reliability, stability, and security of the entire system. Traditional connectors, such as common board-to-board connectors or simple pin-hole connectors, often reveal some technical shortcomings when dealing with applications involving high vibration, high current, or frequent plugging and unplugging.
[0003] Structurally, many connectors employ conductive component designs that lack sufficient axial and radial restraint protection. During mating and unmating processes, or during prolonged use, or when subjected to external impacts or vibrations, the conductive components are prone to loosening, displacement, or even tilting. This instability severely affects the contact pressure and contact area between the conductive components, leading to increased contact resistance, excessive heat generation, significantly reduced connection reliability, and potential safety hazards such as sparks or open circuits.
[0004] Therefore, how to design a connector structure to effectively limit the movement of conductive parts during insertion, removal and use, and ensure stable electrical connection performance is a technical problem that urgently needs to be solved in current connector technology. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings.
[0023] like Figures 1 to 4As shown, the present invention provides a tube-type connector, including a male end 1 and a female end 2. The male end 1 is provided with a first conductive element 3 and a first limiting structure 4 for limiting the first conductive element 3. By constraining and limiting the position of the first conductive element 3 through the first limiting structure 4, the insertion and removal stability and connection reliability of the first conductive element 3 inside the male end 1 can be improved.
[0024] The female end 2 is provided with a second conductive element 5 and a second limiting structure 6 for limiting the second conductive element 5; by constraining and limiting the position of the second conductive element 5 through the second limiting structure 6, the contact stability and safety of the second conductive element 5 inside the female end 2 can be ensured.
[0025] The male terminal 1 and the female terminal 2 are plugged in, and the first conductive element 3 is inserted into the second conductive element 5; the first conductive element 3 and the second conductive element 5 form a tight and stable electrical connection.
[0026] A foolproof structure 7 is provided between male terminal 1 and female terminal 2. The foolproof structure 7 enables the directional connection of male terminal 1 and female terminal 2, and can prevent incorrect insertion or misoperation of male terminal 1 and female terminal 2.
[0027] When the connector is in operation, firstly, the foolproof structure 7 ensures that the male end 1 and the female end 2 can only be aligned in the correct direction, thereby preventing mis-insertion.
[0028] As the male end 1 is pushed toward the female end 2, the first conductive element 3 gradually approaches the second conductive element 5. Throughout the insertion process, the first limiting structure 4 continuously constrains and positions the first conductive element 3, while the second limiting structure 6 also continuously constrains and positions the second conductive element 5, preventing the first conductive element 3 and the second conductive element 5 from shifting or loosening due to insertion force or structural deviation, thus ensuring insertion and extraction stability.
[0029] Finally, male terminal 1 and female terminal 2 are inserted into place, allowing the first conductive element 3 to be inserted into the second conductive element 5. Because the first limiting structure 4 and the second limiting structure 6 ensure the accuracy and stability of the conductive elements in the final connection position, the first conductive element 3 and the second conductive element 5 form a reliable and stable electrical contact, thereby ensuring stable transmission of current or signals and completing the entire connection process.
[0030] like Figure 2 and Figure 3 As shown, the male end 1 in this embodiment includes a housing 11 and an outer cover 12. The housing 11 is provided with a first locking block 111, and the outer cover 12 is provided with a first locking groove 121. The first locking block 111 and the first locking groove 121 are engaged and connected. Through the engaging and cooperating relationship between the first locking block 111 and the first locking groove 121, the housing 11 and the outer cover 12 can be quickly and reliably assembled or fixed. This ensures that the connection between the housing 11 and the outer cover 12 of the male end 1 is firm and not easily loosened, improving the overall structural strength and assembly efficiency of the male end 1.
[0031] like Figure 2 and Figure 3 As shown, the first conductive element 3 in this embodiment is provided with a first limiting part 31; the first conductive element 3 is positioned by the first limiting part 31 in conjunction with the first limiting structure 4.
[0032] The first limiting structure 4 includes a first limiting cavity 41 disposed within the outer casing 11 and an abutment ring 42 disposed inside the outer cover 12. The first limiting part 31 abuts against the first limiting cavity 41 and the abutment ring 42. The first limiting cavity 41 and the abutment ring 42 together form a receiving and abutting space that constrains the first limiting part 31, thereby constraining and positioning the first conductive member 3. This effectively restricts the axial and radial movement of the first conductive member 3 within the male terminal 1, thereby preventing the first conductive member 3 from loosening or shifting, and improving the connection stability and reliability of the male terminal 1.
[0033] like Figure 2 and Figure 3 As shown, one end of the first conductive element 3 in this embodiment is provided with a first welding part 32, which is exposed outside the outer cover 12. The first welding part 32 is used to connect the end of the external cable. At the same time, since the first welding part 32 is exposed outside the outer cover 12, it is convenient to perform welding operations on the external cable.
[0034] The outer wall of the outer cover 12 is provided with a first partition 122 that separates the first welding part 32; the first partition 122 provides physical isolation to the first welding part 32, which can prevent short circuits or interference between adjacent first welding parts 32 and improve the electrical safety of the welding area.
[0035] like Figure 2 and Figure 4 As shown, the female end 2 in this embodiment includes an inner shell 21 and an inner cover 22. The inner shell 21 is provided with a second locking block 211, and the inner cover 22 is provided with a second locking groove 221. The second locking block 211 and the second locking groove 221 are engaged and connected. Through the engagement between the second locking block 211 and the second locking groove 221, the inner shell 21 and the inner cover 22 can be quickly fixed or assembled. This makes the connection between the inner shell 21 and the inner cover 22 of the female end 2 tight and stable, improving the overall structural strength and assembly reliability of the female end 2.
[0036] like Figure 2 and Figure 4 As shown, the second conductive element 5 in this embodiment is provided with a second limiting part 51; the second conductive element 5 is positioned by the second limiting part 51 in conjunction with the second limiting structure 6.
[0037] The second limiting structure 6 includes a second limiting cavity 61 disposed within the inner shell 21 and an abutting portion 62 disposed within the inner cover 22; the second limiting portion 51 abuts against the second limiting cavity 61 and the abutting portion 62. The second limiting cavity 61 and the abutting portion 62 together form a receiving and abutting space that constrains the second limiting portion 51, thereby constraining and positioning the second conductive element 5. This effectively restricts the axial and radial movement of the second conductive element 5 within the female end 2, preventing loosening or displacement of the second conductive element 5 during insertion, removal, or use, thus ensuring the connection stability and reliability of the female end 2.
[0038] like Figure 2 and Figure 4 As shown, in this embodiment, one end of the second conductive member 5 is provided with a second welding portion 52, which is exposed outside the inner cover 22. The second welding portion 52 is the end of the second conductive member 5 used to connect external cables. At the same time, since the second welding portion 52 is exposed outside the inner cover 22, it is convenient for external cables to be welded to the second welding portion 52.
[0039] The outer wall of the inner cover 22 is provided with a second separator 222 that separates the second welding part 52. The second separator 222 provides physical isolation to the second welding part 52, which can prevent short circuits or interference between adjacent second welding parts 52 and improve the electrical safety of the welding area.
[0040] The second separator 222 includes multiple components, with a separator groove 223 formed between two second separators 222. The inner shell 21 is provided with fixing grooves 224 for fixing cables corresponding to the multiple separator grooves 223. The fixing grooves 224 are respectively connected to each separator groove 223. The separator grooves 223 are used to accommodate cables or provide operating space. The fixing grooves 224 cooperate with the separator grooves 223 to guide and fix the cables, which can make the cables connected to the second welding part 52 neat and orderly arranged, and provide reliable mechanical fixation for the cables, preventing the cables from falling off or being damaged when subjected to tension or vibration, thereby improving the reliability of the cable connection.
[0041] like Figure 2 As shown, the foolproof structure 7 in this embodiment includes a protrusion 71 disposed on the inner shell 21 and a guide groove 72 disposed on the outer shell 11. The protrusion 71 slides along the guide groove 72. The protrusion 71 and the guide groove 72 form a unique mating path, realizing the orientation and connection of the male end 1 and the female end 2. The mating method of the protrusion 71 and the guide groove 72 can effectively prevent the male end 1 and the female end 2 from being misaligned, mis-inserted, or reversed during insertion, ensuring the accuracy of the insertion operation and the safety of the connector.
[0042] like Figure 3As shown, the inner shell 21 of this embodiment is provided with a pin fixing hole 212; the pin fixing hole 212 is a structure for accommodating and fixing a pin. The pin fixing hole 212 cooperates with the installation of the pin, which enables the inner shell 21 of the female end 2 to obtain additional positioning and fixation.
[0043] like Figure 4 As shown, the outer casing 11 is provided with a relief groove 112 to avoid the pin fixed in the pin fixing hole 212. The relief groove 112 ensures that the outer casing 11 of the male end 1 and the inner casing 21 of the female end 2 can be smoothly inserted into place, thus ensuring the smooth connection between the male end 1 and the female end 2.
[0044] like Figure 3 and Figure 4 As shown, both the outer cover 12 and the inner cover 22 in this embodiment are provided with crack-prevention grooves 8. By dispersing or terminating the stress concentration generated by the material during molding or use, the crack-prevention grooves 8 prevent further crack propagation. This improves the structural strength, durability, and service life of the outer cover 12 and the inner cover 22, preventing cracking damage during use or impact.
[0045] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
