[0025] Although the present disclosure will be fully described with reference to the accompanying drawings containing preferred embodiments of the present disclosure, it should be understood before this description that a person of ordinary skill in the art can modify the present disclosure described herein while obtaining the technical effects of the present disclosure. Therefore, it should be understood that the above description is a broad disclosure to a person of ordinary skill in the art, and its content is not intended to limit the exemplary embodiments described in the present disclosure.

[0026] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

[0027] According to the overall inventive concept of the present disclosure, a conductive terminal assembly is provided, the conductive terminal assembly comprising a conductive terminal, one end of the conductive terminal forming a plug-in portion, the plug-in portion forming a plug-in cavity for inserting a mating terminal, the conductive terminal assembly further comprising a sleeve sleeved outside the plug-in portion and a locking structure for fixing the sleeve and the plug-in portion together, the locking structure comprising a protrusion protruding from one of the side walls of the plug-in portion and the side walls of the sleeve toward the other, the protrusion cooperating with the other of the side walls of the plug-in portion and the side walls of the sleeve to inhibit the movement of the sleeve relative to the plug-in portion.

[0028] According to another general inventive concept of the present disclosure, a connector is provided, which includes a housing and a conductive terminal assembly. The conductive terminal assembly is fixed in the housing, and the conductive terminal assembly is the conductive terminal assembly according to the embodiment of the present disclosure.

[0029] like Figure 1 As shown, the conductive terminal assembly 100 according to the exemplary embodiment of the present disclosure includes a conductive terminal 10, one end of which is formed with a cylindrical plug-in portion 11, and the plug-in portion 11 is formed with a plug-in cavity for inserting a mating terminal (not shown). The conductive terminal assembly 100 also includes a sleeve 20 sleeved on the outside of the plug-in portion 11, and the sleeve 20 can provide a certain holding force for the conductive terminal 10 to maintain the stable contact between the conductive terminal 10 and the mating terminal. In addition, the conductive terminal assembly 100 also includes a locking structure for fixing the sleeve 20 and the plug-in portion 11 together. The locking structure includes a protrusion 23 protruding from the side wall of the sleeve 20 toward the side wall of the plug-in portion 11, and the protrusion 23 cooperates with the side wall of the plug-in portion 11 to inhibit the movement of the sleeve 20 relative to the conductive terminal 10. Compared with the technical solution of interference fit between the sleeve and the conductive terminal in the prior art, the conductive terminal assembly according to the exemplary embodiment of the present disclosure makes the sleeve and the conductive terminal fit only at the position where the protrusion is located, thereby reducing the sensitivity of the conductive terminal assembly to size and shape changes, and can improve production efficiency and reduce manufacturing costs.

[0030] It should be noted that in some other embodiments of the present disclosure, the protrusion may also be formed on the side wall of the plug-in portion 11. When the protrusion is formed on the side wall of the plug-in portion, it protrudes toward the side wall of the sleeve and interferes with the side wall of the sleeve, thereby fixing the sleeve 20 and the conductive terminal 10 together.

[0031] According to an exemplary embodiment of the present disclosure, Figure 2 and Figure 3 As shown, the protrusion 23 is in the form of a buckle, and the locking structure also includes a slot 13 formed on the side wall of the plug-in portion 11. The sleeve 20 and the conductive terminal 10 are fixed together by the cooperation between the buckle and the slot 13, which can improve the connection reliability of the sleeve 20 and the conductive terminal 10. It should be noted that in some other embodiments of the present disclosure, the buckle can be formed on the plug-in portion 11, and the slot can be formed on the side wall of the sleeve 20.

[0032] According to an exemplary embodiment of the present disclosure, Figure 4 As shown, a convex rib 231 is formed on the buckle to improve the buckle strength and increase the holding force, thereby improving the connection reliability between the conductive terminal 10 and the mating terminal.

[0033] According to an exemplary embodiment of the present disclosure, Figure 2 As shown, the buckle can be a spring extending obliquely from the side wall of the sleeve 20 toward the plug interface and toward the central axis of the sleeve 20, and the slot 13 can be a through hole (such as Figure 1It should be noted that the buckle and the slot 13 may also respectively adopt other structures known in the prior art.

[0034] According to another exemplary embodiment of the present disclosure, Figure 1 As shown, the protrusion 23 is formed by bending one end of the sleeve 20 away from the plug interface of the plug cavity toward the plug portion 11. It should be noted that when the protrusion is formed on the plug portion 11, the protrusion can also be formed by bending one end of the plug portion 11 away from the plug interface of the plug cavity toward the sleeve 20.

[0035] According to an exemplary embodiment of the present disclosure, Figure 2 As shown, there are multiple locking structures, which are arranged at intervals 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 overall force on the plug-in part 11 in the circumferential direction more uniform.

[0036] According to another exemplary embodiment of the present disclosure, Figure 5 As shown, there are multiple locking structures, which are arranged at intervals 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 overall force on the plug-in part 11 in the axial direction more uniform.

[0037] According to another exemplary embodiment of the present disclosure, Figure 2 and Figure 5 As shown, the sleeve 20 includes a substantially cylindrical sleeve body 21 and a locking boss 22 protruding outwardly from the sleeve body 21 in a radial direction, and the locking boss 22 can cooperate with the housing of the connector (not shown) to fix the conductive terminal assembly 100 in the housing of the connector. According to the conductive terminal assembly 100 of the exemplary embodiment of the present disclosure, the locking boss 22 that cooperates with the housing of the connector is formed on the sleeve 20 to fix the conductive terminal assembly 100 in the housing of the connector, thereby avoiding machining bosses on the conductive terminal 10, thereby facilitating the shortening of the terminal length and thus reducing costs. At the same time, since the material hardness of the sleeve 20 is generally higher than that of the conductive terminal 10 and the thickness is thinner, the problem of metal wire generated during the machining of the conductive terminal assembly 100 can be reduced or eliminated.

[0038] According to an exemplary embodiment not shown in the present disclosure, the locking boss 22 includes a first locking boss and a second locking boss, and the first locking boss and the second locking boss are arranged at intervals along the axial direction of the sleeve 20, so that the first locking boss can cooperate with the housing of the connector to form a primary locking structure for locking the conductive terminal assembly 100 with the housing of the connector, and the second locking boss can cooperate with the housing of the connector to form a secondary locking structure for locking the conductive terminal assembly 100 with the housing of the connector. It should be noted that in some other embodiments of the present disclosure, the number of locking bosses 22 can also be other values, such as 3, 4, etc., and the specific number can be specifically designed according to specific circumstances.

[0039] According to an exemplary embodiment of the present disclosure, Figure 1 and Figure 2 As shown, one end of the sleeve 20 corresponding to the plug-in interface of the plug-in cavity of the conductive terminal 10 is bent into the plug-in cavity to form a stopper 24, which is used to stop the conductive terminal 10 from moving forward (ie, toward Figure 2 to the right in the image.

[0040] According to an exemplary embodiment of the present disclosure, the sleeve 20 can be formed by bending a metal sheet. In addition, in order 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.

[0041] According to an exemplary embodiment of the present disclosure, Figure 2 As shown, according to the conductive terminal assembly 100 of the present application, the clip can be embedded in the groove 13 through a stamping process. Since the sleeve 20 can be processed 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 dimensional changes of the two parts, thereby greatly reducing the difficulty of manufacturing the parts and ensuring more stable product quality.

[0042] According to an exemplary embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 7As shown, the plug-in portion 11 of the conductive terminal 10 has three contact units, and the three contact units are arranged at equal intervals around the circumference of the plug-in portion 11, so that the overall force of the plug-in portion 11 is relatively uniform, and the conductive terminal 10 is not easily damaged. Wherein. Each contact unit includes two contact portions for electrically contacting the mating terminal: a first contact portion 15A and a second contact portion 15B, and the two contact portions are arranged at intervals along the direction of the central axis of the plug-in 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. According to the conductive terminal assembly 100 of the embodiment of the present disclosure, at least two contacts are arranged in the axial direction of the conductive terminal 10, thereby reducing the contact resistance, and at the same time improving the contact stability between the conductive terminal 10 and the mating terminal along the axial direction, thereby improving the reliability of the connection between the conductive terminal 10 and the mating terminal.

[0043] It should be noted that although Figure 2 , Figure 3 and Figure 7 In the embodiment shown, three contact units are shown. However, in some other embodiments of the present disclosure, the number of contact units may be other values, such as 1, 2, 4, etc. Figure 2 and Figure 7 In the illustrated embodiment, three contact units are arranged at equal intervals around the circumference of the plug-in portion 11 . However, in some other embodiments of the present disclosure, a plurality of contact units may also be arranged at unequal intervals around the circumference of the plug-in portion 11 .

[0044] According to an exemplary embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 7 As shown, each contact unit includes two contact portions for electrically contacting the mating terminal. However, in some other embodiments of the present disclosure, each contact unit may also include other numbers of contact portions, such as 3, 4, 5, etc. These contact portions are spaced apart along the direction of the central axis of the plug-in portion 11 to improve the contact stability between the conductive terminal 10 and the mating terminal along the axial direction.

[0045] According to an exemplary embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 7As shown, the plug-in portion 11 has a first cantilever 14A and a second cantilever 14B, the first cantilever 14A extends obliquely away from the plug-in interface and toward the central axis of the plug-in portion 11, and the second cantilever 14B extends obliquely toward the plug-in interface and toward the central axis of the plug-in portion 11, wherein the first contact portion 15A is arranged on the first cantilever 14A, and the first contact portion 15A is the portion of the entire first cantilever 14A closest to the central axis of the plug-in portion 11, similarly, the second contact portion 15B is arranged on the second cantilever 14B, and the second contact portion 15B 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 through the circumferential side wall of the plug-in portion 11, and the first cantilever 14A and the second cantilever 14B are inclined toward the central axis of the plug-in portion while extending, so that the first contact portion 15A and the second contact portion 15B abut against the mating terminal when the mating terminal is inserted into the plug-in cavity. 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.

[0046] According to an exemplary embodiment not shown in the present disclosure, the plug-in portion 11 may have a first cantilever and a second cantilever, the first cantilever is away from the plug-in interface and extends obliquely toward the central axis of the plug-in portion 11, and the second cantilever is also away from the plug-in interface and extends obliquely toward the central axis of the plug-in portion 11, wherein the first contact portion is arranged on the first cantilever, and the first contact portion is the portion of the entire first cantilever closest to the central axis of the plug-in portion 11, similarly, the second contact portion is arranged on the second cantilever, and the second contact portion is the portion of the entire second cantilever closest to the central axis of the plug-in portion 11. That is, the first cantilever and the second cantilever both extend away from the plug-in interface in the direction of the central axis of the plug-in portion 11, and the first cantilever and the second cantilever both tilt toward the central axis of the plug-in cavity while extending, so that the first contact portion and the second contact portion abut against the mating terminal when the mating terminal is inserted into the mating 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.

[0047] It should be noted that although Figure 7 In the illustrated embodiment, the first cantilevers 14A of all contact units are aligned along the circumference of the plug-in portion 11, and the first contact portion 15A is also aligned along the circumference of the plug-in portion 11, the second cantilevers 14B of all contact units are aligned along the circumference of the plug-in portion 11, and the second contact portion 15B is also aligned along the circumference of the plug-in portion 11; however, in some other embodiments of the present disclosure, the first cantilevers 14A and the first contact portions 15A in all contact units may also be staggered in the circumferential direction of the plug-in portion 11, and the second cantilevers 14B and the second contact portions 15B in all contact units may also be staggered in the circumferential direction of the plug-in portion 11, respectively.

[0048] According to another exemplary embodiment of the present disclosure, Figure 6 As shown, the plug-in portion 11 has a third cantilever 14, which is away from the plug-in interface and extends obliquely toward the central axis of the plug-in portion 11, wherein the first contact portion 15A and the second contact portion 15B are both arranged on the third cantilever 14. It should be noted that in some other embodiments of the present disclosure, the third cantilever 14 may also extend obliquely toward the plug-in interface and toward the central axis of the plug-in portion 11.

[0049] It should be noted that although Figure 6 In the illustrated embodiment, the third cantilevers 14, the first contact portion 15A and the second contact portion 15B of all contact units are respectively aligned along the circumference of the plug-in portion 11; however, in some other embodiments of the present disclosure, the third cantilevers 14, the first contact portion 15A and the second contact portion 15B in all contact units may also be respectively staggered in the circumferential direction of the plug-in portion 11.

[0050] According to an exemplary embodiment of the present disclosure, Figure 6 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-in portion 11 to abut against the sleeve 20 outside the plug-in portion 11, so as to apply a force to the third cantilever 14 through the sleeve 20, thereby making the two contact portions stably contact with the mating terminal.

[0051] According to an exemplary embodiment of the present disclosure, Figure 2 and Figure 3 As shown, the conductive terminal 10 further includes a wiring portion 12 located at an end opposite to the plug-in portion 11 and an intermediate portion connecting the plug-in portion 11 and the wiring portion 12. The wiring portion 12 is "U"-shaped so as to clamp and fix and electrically connect a cable (not shown).

[0052] According to another aspect of the present disclosure, a connector is provided. The connector includes a housing and a conductive terminal assembly 100. The conductive terminal assembly 100 is fixed in the housing and is the conductive terminal assembly 100 according to an embodiment of the present disclosure.

[0053] According to the conductive terminal assembly and connector of the above various embodiments of the present disclosure, a protrusion protruding toward the other side wall of the plug-in part and the side wall of the sleeve is formed on one of the side walls of the plug-in part and the side wall of the sleeve, and the protrusion cooperates with the other side wall of the plug-in part and the side wall of the sleeve to inhibit the movement of the sleeve relative to the plug-in part, that is, the sleeve and the conductive terminal only cooperate at the position where the protrusion is located, thereby reducing the sensitivity of the conductive terminal assembly to size and shape changes, and can improve production efficiency and reduce manufacturing costs. Further, the protrusion can be in the form of a buckle, and the sleeve and the conductive terminal are fixed together by forming a card groove that cooperates with the buckle on the other side wall of the plug-in part and the side wall of the sleeve, which can greatly improve the connection reliability of the conductive terminal and the sleeve. In addition, the conductive terminal assembly can embed the buckle into the groove by stamping technology. Since the sleeve can be processed by bending and forming rather than drawing, the stamping process and the assembly process can be integrated into a set of molds, thereby greatly reducing the requirements for the roundness and size changes of the two parts, thereby greatly reducing the difficulty of manufacturing the parts and ensuring more stable product quality.
