[0034] Detailed Description of Embodiments. While this disclosure will be fully described with reference to the accompanying drawings containing preferred embodiments, it should be understood before this description that those skilled in the art can modify the disclosure described herein to obtain the technical effects of this disclosure. Therefore, it should be understood that the above description is a broad disclosure to those skilled in the art and is not intended to limit the exemplary embodiments described herein.

[0035] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0036] According to the general inventive concept of this disclosure, a conductive terminal assembly is provided, which includes a conductive terminal, one end of the conductive terminal having a plug portion, the plug portion having a plug cavity for inserting a mating terminal, the free end of the plug cavity forming a plug interface, the plug portion having at least one contact unit, the at least one contact unit including at least two contact portions for electrical contact with the mating terminal, the at least two contact portions being spaced apart along the central axis of the plug portion.

[0037] According to another general inventive concept of this disclosure, a connector is provided, the connector including a housing and a conductive terminal assembly fixed within the housing, and the conductive terminal assembly is a conductive terminal assembly according to an embodiment of this disclosure.

[0038] like Figures 1 to 3As shown, the conductive terminal assembly 100 according to an embodiment of the present disclosure includes a conductive terminal 10, one end of which is formed with a cylindrical insertion portion 11. The insertion portion 11 has an insertion cavity for inserting a mating terminal (not shown). The insertion portion 11 of the conductive terminal 10 has three contact units, which are equally spaced around the circumference of the insertion portion 11 to ensure that the insertion portion 11 is subjected to more uniform force and that the conductive terminal 10 is less susceptible to damage. Each contact unit includes two contact portions for electrical contact with the mating terminal: a first contact portion 15A and a second contact portion 15B, which are spaced apart along the central axis of the insertion portion 11. When the mating terminal is inserted, the first contact portion 15A and the second contact portion 15B successively contact the mating terminal and form an electrical connection. The conductive terminal assembly 100 according to the embodiments of the present disclosure reduces the contact resistance by providing at least two contact portions in the axial direction of the conductive terminal 10, and improves the contact stability between the conductive terminal 10 and the mating terminal in the axial direction, thereby improving the reliability of the connection between the conductive terminal 10 and the mating terminal.

[0039] It should be noted that, although in Figures 1 to 3 In the illustrated embodiment, three contact units are shown; however, in other embodiments of this disclosure, the number of contact units may be other values, such as one, two, four, etc. Furthermore, although in Figures 1 to 3 In the illustrated embodiment, three contact units are arranged at equal intervals around the circumference of the plug-in portion 11. However, in other embodiments of this disclosure, multiple contact units may be arranged at unequal intervals around the circumference of the plug-in portion 11.

[0040] According to exemplary embodiments of this disclosure, such as Figures 1 to 3 As shown, each contact unit includes two contact portions for electrical contact with the mating terminal. However, in some other embodiments of this disclosure, each contact unit may also include other numbers of contact portions, such as three, four, five, etc. These contact portions are spaced apart along the central axis of the plug portion 11 to improve the contact stability of the conductive terminal 10 and the mating terminal in the axial direction.

[0041] According to exemplary embodiments of this disclosure, such as Figures 1 to 3As shown, the plug-in portion 11 has a first cantilever 14A and a second cantilever 14B. The first cantilever 14A extends obliquely from approximately the center of the plug-in portion 11 away from the plug-in interface and toward the central axis of the plug-in portion 11. The second cantilever 14B extends obliquely from approximately the center of the plug-in portion 11 toward the plug-in interface and toward the central axis of the plug-in portion 11. A first contact portion 15A is provided on the first cantilever 14A and is the portion of the entire first cantilever 14A closest to the central axis of the plug-in portion 11. Similarly, a second contact portion 15B is provided on the second cantilever 14B and is the portion of the entire second cantilever 14B closest to the central axis of the plug-in portion 11. The first cantilever 14A and the second cantilever 14B are connected together by a circumferential sidewall located at the middle of the insertion portion 11. The first cantilever 14A and the second cantilever 14B extend and are inclined toward the central axis of the insertion portion so that when the mating terminal is inserted into the insertion cavity, the first contact portion 15A and the second contact portion 15B abut against the mating terminal. Preferably, the first contact portion 15A is formed at the free end of the first cantilever 14A, and the second contact portion 15B is formed at the free end of the second cantilever 14B.

[0042] According to exemplary embodiments of this disclosure, such as Figure 4 As shown, the plug-in portion 11 has a first cantilever 14A and a second cantilever 14B. The first cantilever 14A extends obliquely from the end of the plug-in portion 11 away from the plug-in interface toward the plug-in interface and toward the central axis of the plug-in portion 11. The second cantilever 14B extends obliquely from approximately the middle of the plug-in portion 11 toward the plug-in interface and toward the central axis of the plug-in portion 11. A first contact portion 15A is provided on the first cantilever 14A and is the part of the entire first cantilever 14A closest to the central axis of the plug-in portion 11. Similarly, a second contact portion 15B is provided on the second cantilever 14B and is the part of the entire second cantilever 14B closest to the central axis of the plug-in portion 11. The first cantilever 14A and the second cantilever 14B are connected together by the circumferential sidewall of the insertion portion 11. The first cantilever 14A and the second cantilever 14B extend while tilting towards the central axis of the insertion portion, so that when the mating terminal is inserted into the insertion cavity, the first contact portion 15A and the second contact portion 15B abut against the mating terminal. Preferably, the first contact portion 15A is formed at the free end of the first cantilever 14A, and the second contact portion 15B is formed at the free end of the second cantilever 14B. In this embodiment, by tilting the first cantilever 14A, which is furthest from the insertion interface of the insertion portion 11, towards the insertion interface and towards the central axis of the insertion portion 11, the distance between the first contact portion 15A, which is furthest from the insertion interface of the insertion portion 11, and the insertion interface is minimized. This results in a shorter mating length for the mating terminal (not shown) inserted into the insertion cavity of the conductive terminal 10, thereby reducing the cost of the mating terminal.

[0043] According to exemplary embodiments of this disclosure, such as Figure 5 As shown, the plug-in portion 11 has a first cantilever 14A and a second cantilever 14B. The first cantilever 14A extends obliquely from the end of the plug-in portion 11 away from the plug-in interface toward the plug-in interface and toward the central axis of the plug-in portion 11. The second cantilever 14B extends obliquely from the end of the plug-in portion 11 near the plug-in interface away from the plug-in interface and toward the central axis of the plug-in portion 11. A first contact portion 15A is provided on the first cantilever 14A and is the part of the entire first cantilever 14A closest to the central axis of the plug-in portion 11. Similarly, a second contact portion 15B is provided on the second cantilever 14B and is the part of the entire second cantilever 14B closest to the central axis of the plug-in portion 11. The first cantilever 14A and the second cantilever 14B are connected together by the circumferential sidewall of the insertion portion 11. The first cantilever 14A and the second cantilever 14B extend while tilting towards the central axis of the insertion portion, so that when the mating terminal is inserted into the insertion cavity, the first contact portion 15A and the second contact portion 15B abut against the mating terminal. Preferably, the first contact portion 15A is formed at the free end of the first cantilever 14A, and the second contact portion 15B is formed at the free end of the second cantilever 14B. In this embodiment, by tilting the first cantilever 14A, which is furthest from the insertion interface of the insertion portion 11, towards the insertion interface and towards the central axis of the insertion portion 11, the distance between the first contact portion 15A, which is furthest from the insertion interface of the insertion portion 11, and the insertion interface is minimized. This results in a shorter mating length for the mating terminal (not shown) inserted into the insertion cavity of the conductive terminal 10, thereby reducing the cost of the mating terminal.

[0044] According to an exemplary embodiment not shown in this disclosure, the plug-in portion 11 may have a first cantilever and a second cantilever. The first cantilever extends obliquely from approximately the middle of the plug-in portion away from the plug interface and toward the central axis of the plug-in portion 11. The second cantilever extends obliquely from one end of the plug-in portion near the plug interface away from the plug interface and toward the central axis of the plug-in portion 11. A first contact portion is provided on the first cantilever, and the first contact portion is the part of the entire first cantilever closest to the central axis of the plug-in portion 11. Similarly, a second contact portion is provided on the second cantilever, and the second contact portion is the part of the entire second cantilever closest to the central axis of the plug-in portion 11. That is, both the first and second cantilever extend away from the plug interface along the direction of the central axis of the plug-in portion 11, and both the first and second cantilever extend obliquely toward the central axis of the plug cavity so that the first and second contact portions abut against the mating terminals when the mating terminals are inserted into the plug cavity. Preferably, the first contact portion is formed at the free end of the first cantilever, and the second contact portion is formed at the free end of the second cantilever.

[0045] It should be noted that, although in Figure 3 , Figure 4 , Figure 5 In the illustrated embodiment, the first cantilever 14A of all contact units is aligned circumferentially along the insertion portion 11, and the first contact portion 15A is also aligned circumferentially along the insertion portion 11. The second cantilever 14B of all contact units is aligned circumferentially along the insertion portion 11, and the second contact portion 15B is also aligned circumferentially along the insertion portion 11. However, in some other embodiments of this disclosure, the first cantilever 14A and the first contact portion 15A of all contact units may also be misaligned in the circumferential direction of the insertion portion 11, and the second cantilever 14B and the second contact portion 15B of all contact units may also be misaligned in the circumferential direction of the insertion portion 11.

[0046] According to another exemplary embodiment of this disclosure, such as Figure 6 As shown, the plug-in portion 11 has a third cantilever 14, which extends obliquely from the end of the plug-in portion 11 near the plug-in interface, away from the plug-in interface, and toward the central axis of the plug-in portion 11. The first contact portion 15A and the second contact portion 15B are both disposed on the third cantilever 14. It should be noted that in some other embodiments of this disclosure, the third cantilever 14 may also extend obliquely from the end of the plug-in portion 11 away from the plug-in interface, toward the plug-in interface, and toward the central axis of the plug-in portion 11.

[0047] It should be noted that, although in Figure 5 In the illustrated embodiment, the third cantilever 14, the first contact portion 15A, and the second contact portion 15B of all contact units are aligned circumferentially along the insertion portion 11. However, in some other embodiments of this disclosure, the third cantilever 14, the first contact portion 15A, and the second contact portion 15B of all contact units may also be misaligned in the circumferential direction of the insertion portion 11.

[0048] According to exemplary embodiments of this disclosure, such as Figure 7 As shown, the portion of the third cantilever 14 located between the first contact portion 15A and the second contact portion 15B protrudes outward away from the central axis of the plug portion 11 to abut against the sleeve 20 or the housing of the connector outside the plug portion 11. In this way, a force can be applied to the third cantilever 14 through the sleeve 20 or the housing, thereby making the two contact portions stably contact the mating terminals.

[0049] According to exemplary embodiments of this disclosure, such as Figure 1 , Figure 2 and Figures 4 to 11 As shown, the conductive terminal 10 also includes a wiring portion 12 located at the end opposite to the plug portion 11 and an intermediate portion connecting the plug portion 11 and the wiring portion 12. The wiring portion 12 is U-shaped to clamp, fix and electrically connect a cable (not shown).

[0050] According to exemplary embodiments of this disclosure, such as Figure 5 and Figure 7 As shown, a locking boss 16 is formed on the conductive terminal 10. The locking boss 16 can cooperate with the housing (not shown) of the connector to fix the conductive terminal assembly 100 inside the housing of the connector.

[0051] According to exemplary embodiments of this disclosure, such as Figures 8 to 11 As shown, the conductive terminal assembly 100 also includes a sleeve 20 sleeved outside the plug portion 11. The sleeve 20 can provide a certain holding force for the conductive terminal 10 to maintain stable contact between the conductive terminal 10 and the mating terminal.

[0052] According to exemplary embodiments of this disclosure, such as Figures 8 to 9 As shown, the sleeve 20 includes a generally cylindrical sleeve body 21 and a circumferential locking boss 22 protruding radially outward from the sleeve body 21. The circumferential locking boss 22 can mate with the connector housing (not shown) to fix the conductive terminal assembly 100 within the connector housing. According to an exemplary embodiment of the present disclosure, the conductive terminal assembly 100 is fixed within the connector housing by forming a circumferential locking boss 22 on the sleeve 20 that mates with the connector housing. This avoids machining a boss on the conductive terminal 10, thereby facilitating a reduction in terminal length and thus lowering costs. Furthermore, since the material of the sleeve 20 is typically harder and thinner than that of the conductive terminal 10, the problem of metal wires generated during the machining of the conductive terminal 10 can be reduced or eliminated.

[0053] According to an exemplary embodiment not shown in this disclosure, the circumferential locking boss 22 includes a first circumferential locking boss and a second circumferential locking boss, which are spaced apart along the axial direction of the sleeve 20. This allows the first circumferential locking boss to engage with the connector housing to form a primary locking structure that locks the conductive terminal assembly 100 to the connector housing. Simultaneously, the second circumferential locking boss can engage with the connector housing to form a secondary locking structure that locks the conductive terminal assembly 100 to the connector housing. It should be noted that in other embodiments of this disclosure, the number of circumferential locking bosses 22 can be other values, such as 3 or 4, and the specific number can be designed according to specific circumstances.

[0054] According to an exemplary embodiment of this disclosure, such as Figure 11As shown, the sleeve 20 is provided with a locking buckle 25 that extends obliquely from the central axis of the sleeve body 21 away from the insertion interface and away from the insertion portion 11. The locking buckle 25 can cooperate with the housing of the connector (e.g., a slot formed on the connector housing) to fix the conductive terminal assembly 100 inside the housing of the connector.

[0055] According to an exemplary embodiment of this disclosure, such as Figures 9 to 11 As shown, the conductive terminal assembly 100 also includes a locking structure for securing the sleeve body 21 to the conductive terminal 10. Specifically, as Figure 9 , Figure 10 and Figure 11 As shown, the locking structure includes a groove 13 formed on the conductive terminal 10 and a latch 23 formed on the side wall of the sleeve 20. The sleeve 20 can be fixed to the conductive terminal 10 by the cooperation of the latch 23 and the groove 13. It should be noted that in some other embodiments of this disclosure, the latch of the locking structure can be formed on the conductive terminal 10, while the groove can be formed on the side wall of the sleeve 20.

[0056] According to an exemplary embodiment of this disclosure, such as Figure 9 As shown, there are multiple locking structures, which are spaced apart along the circumference of the sleeve 20 to increase the holding force, thereby improving the connection reliability between the conductive terminal 10 and the mating terminal, and making the insertion part 11 more uniformly stressed in the circumferential direction.

[0057] According to an exemplary embodiment not shown in this disclosure, multiple locking structures may also be spaced apart along the axial direction of the sleeve 20 to increase the holding force, thereby improving the connection reliability between the conductive terminal 10 and the mating terminal, and making the insertion portion 11 more uniformly stressed in the axial direction.

[0058] According to another exemplary embodiment of this disclosure, such as Figure 8 As shown, the end of the sleeve 20 away from the insertion interface of the insertion cavity is formed with a protrusion 27 protruding toward the conductive terminal 10 to increase the thickness of the sleeve 20, thereby increasing the holding force provided by the sleeve 20 for the conductive terminal 10.

[0059] According to an exemplary embodiment of this disclosure, such as Figure 9 As shown, one end of the sleeve 20 corresponding to the insertion interface of the insertion cavity of the conductive terminal 10 is bent into the insertion cavity to form a stop portion 24, which is used to stop the conductive terminal 10 from moving forward (i.e., towards) the insertion cavity. Figure 9 (Move to the right of the middle)

[0060] According to an exemplary embodiment of this disclosure, the sleeve 20 can be formed by bending a metal sheet. Furthermore, to ensure the strength of the sleeve 20, the material of the sleeve 20 is preferably stainless steel. In other embodiments, the sleeve 20 can also be made of other metal materials, preferably materials with higher hardness and thinner thickness than the conductive terminal 10.

[0061] According to an exemplary embodiment of this disclosure, such as Figure 9 As shown, the conductive terminal assembly 100 according to this application can embed the buckle 23 into the groove 13 by stamping technology. Since the sleeve 20 can be formed by bending rather than drawing, the stamping process and the assembly process can be integrated into a set of molds, which can greatly reduce the requirements for the roundness and size of the two parts, thereby greatly reducing the manufacturing difficulty of the parts and ensuring more stable product quality.

[0062] According to another aspect of this disclosure, a connector is also provided, the connector including a housing and a conductive terminal assembly 100 fixed within the housing, and the conductive terminal assembly 100 is a conductive terminal assembly 100 according to an embodiment of this disclosure.

[0063] According to the conductive terminal assembly and connector of the various embodiments described above, by providing at least two contacts in the axial direction of the conductive terminal, the contact resistance is reduced, and the contact stability of the conductive terminal and the mating terminal in the axial direction is improved, thereby improving the reliability of the connection between the conductive terminal and the mating terminal.

[0064] Those skilled in the art will understand that the embodiments described above are exemplary and can be improved upon. The structures described in the various embodiments can be freely combined without causing any conflict in structure or principle.

[0065] Although this disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this disclosure and should not be construed as a limitation thereof.

[0066] While some embodiments of the present general inventive concept have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the present general disclosure, the scope of which is defined by the claims and their equivalents.

[0067] It should be noted that the word "comprising" does not exclude other elements or steps, and the words "a" or "an" do not exclude multiple. Furthermore, any element reference numerals in the claims should not be construed as limiting the scope of this disclosure.
