Description

Technical Field

[0001] This utility model relates to the technical field of connectors, specifically to a multi-contact circular conductive terminal, a conductive terminal assembly, and a connector. Background Technology

[0002] In existing connectors, some terminals are circular. These circular terminals typically use a simple-beam-like elastic element to clamp and electrically connect with the mating connector. The limited number of contact points between this elastic element and the mating terminal in existing connectors leads to unstable or excessive insertion and extraction forces. This clamping force is highly sensitive to changes in the dimensions of the mating components, resulting in significant variations in insertion and extraction forces when the dimensions of the mating components change. Furthermore, the limited number of contact points restricts the connector's current-carrying capacity. Utility Model Content

[0003] In order to overcome the above-mentioned or other defects in the prior art, this utility model proposes a novel circular conductive terminal, which adds a spring piece similar to a cantilever beam to the existing simply supported beam, thereby increasing the number of contact points and improving the insertion and extraction force.

[0004] According to one aspect of the present invention, a conductive terminal is provided, characterized in that it includes a plug portion disposed at one end thereon, the plug portion having a plug cavity formed thereon for inserting a mating terminal, wherein a cantilever extending toward the interior of the plug cavity is disposed thereon, and the free end of the cantilever is configured to contact the mating terminal to achieve electrical connection.

[0005] In an exemplary embodiment, the fixed end of the cantilever is integrally formed with the sidewall of the plug portion, and the cantilever has a curved portion recessed toward the center of the plug cavity near the free end, wherein the recessed portion of the curved portion can contact the mating terminal, and the free end of the cantilever extends away from the center of the plug portion to facilitate the insertion of the mating terminal.

[0006] In an exemplary embodiment, the sidewall of the plug portion is provided with an opening parallel to the axial direction of the plug cavity, and the cantilever extends from one end of the opening along the opening toward the insertion port of the plug cavity.

[0007] In one exemplary embodiment, the sidewall of the plug portion has a protrusion that protrudes toward the interior of the plug cavity, the protrusion being configured to contact the mating terminal when the mating terminal is inserted into the plug cavity to achieve an electrical connection.

[0008] In an exemplary embodiment, the protrusion of the sidewall of the plug portion is offset from the bend of the cantilever along the axial direction of the plug cavity.

[0009] In an exemplary embodiment, the protrusion of the sidewall of the insertion portion is formed by the sidewall being recessed toward the center of the insertion cavity.

[0010] In one exemplary embodiment, the insertion portion of the conductive terminal is a single piece.

[0011] In one exemplary embodiment, the cantilever is a conductive spring, and the sidewall is conductive.

[0012] In one exemplary embodiment, there are multiple cantilever arms arranged circumferentially around the insertion cavity, and multiple protrusions on the sidewalls arranged circumferentially around the insertion cavity.

[0013] According to another embodiment of the present invention, a conductive terminal assembly is provided, characterized in that it includes a sleeve and the aforementioned conductive terminal, wherein the sleeve is sleeved outside the insertion portion of the conductive terminal and is fixed to the insertion portion.

[0014] In one exemplary embodiment, the conductive terminal assembly further includes a locking structure for securing the sleeve to the plug portion, the locking structure including a protrusion projecting from one of the sidewalls of the plug portion and the sidewall of the sleeve toward the other, the protrusion engaging with the other of the sidewalls of the plug portion and the sidewall of the sleeve to inhibit movement of the sleeve relative to the plug portion.

[0015] According to another embodiment of the present invention, a connector is provided, characterized in that it includes a housing and a conductive terminal assembly fixed within the housing, wherein the conductive terminal assembly is the aforementioned conductive terminal assembly.

[0016] In the foregoing exemplary embodiments of this invention, a cantilever-beam-like spring contact is added to the existing simply supported beam of the circular terminal, and the contacts of the spring contact and the contacts of the simply supported beam are offset from each other along the axial direction of the terminal, resulting in more stable insertion and extraction force performance. Under the same conditions, the clamping force generated by the cantilever beam varies less with the interference fit. The tolerance requirements for component manufacturing are relatively fewer, making manufacturing simpler. Furthermore, a greater number of contact points is beneficial to the electrical performance of the connector. The axially offset contact point design helps reduce the connector operating force. The circular terminal of this invention can be used alone or in conjunction with a light-body protective sleeve or a locking gun protective sleeve to meet different application needs.

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.

[0022] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a full 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.

[0023] According to the overall concept of this utility model, a conductive terminal is provided, including a plug portion disposed at one end thereto, wherein a plug cavity is formed on the plug portion for inserting a mating terminal, wherein a cantilever extending toward the interior of the plug cavity is disposed on the plug cavity, and the free end of the cantilever is configured to contact the mating terminal to achieve electrical connection.

[0024] According to the overall concept of this utility model, a conductive terminal assembly is also provided, including a sleeve and the aforementioned conductive terminal, wherein the sleeve is sleeved outside the insertion portion of the conductive terminal and fixed to the insertion portion.

[0025] According to the overall concept of this utility model, a connector is also provided, including a housing and a conductive terminal assembly fixed within the housing, wherein the conductive terminal assembly is the aforementioned conductive terminal assembly.

[0026] The advantages of the conductive terminal according to this invention are that it incorporates a cantilever beam-like spring, resulting in more stable insertion and extraction force performance. Under the same conditions, the clamping force generated by the cantilever beam varies less with the interference fit. This simplifies manufacturing by reducing tolerance requirements for components. Furthermore, the increased number of contact points improves the connector's electrical performance. The circular terminal of this invention can be used alone or in conjunction with a protective sleeve or a locking sleeve to form a conductive terminal assembly, meeting diverse application needs.

[0027] Figure 1 This is a perspective view of the conductive terminal 1 according to an exemplary embodiment of the present invention; Figure 2 This is a front view of the end of a conductive terminal 1 according to an exemplary embodiment of the present invention.

[0028] As shown in the figure, the conductive terminal 1 according to the present invention includes a plug portion 11 disposed at one end thereon, the plug portion 11 having a plug cavity 12 for inserting a mating terminal, the plug cavity 12 having an overall cylindrical shape, wherein the plug cavity 12 is provided with a cantilever 13 extending toward the interior of the plug cavity 12, the free end 14 of the cantilever 13 being configured to contact the mating terminal to achieve electrical connection.

[0029] The fixed end of the cantilever 13 is integrally formed with the side wall 15 of the plug-in portion 11. The cantilever 13 has a curved portion 16 that is recessed toward the center of the plug-in cavity 12 near the free end 14. The recessed portion of the curved portion 16 can contact the mating terminal when the mating terminal is inserted into the plug-in cavity 12, thereby forming an electrical connection with the mating terminal. The free end 14 of the cantilever 13 extends away from the center of the plug-in portion 11 to facilitate the insertion of the mating terminal.

[0030] The side wall 15 of the insertion portion 11 has an opening 17 parallel to the axial direction of the insertion cavity 12. The cantilever 13 extends from one end of the opening 17 toward the insertion port 18 of the insertion cavity 12. Those skilled in the art will understand that the extension direction of the cantilever 13 is not limited to the aforementioned direction; it can also extend from one end of the opening 17 near the insertion port 18 toward the other end of the insertion cavity 12, as long as the free end of the cantilever 13 can contact the mating terminal.

[0031] The sidewall 15 of the plug portion 11 has a protrusion 19 protruding toward the interior of the plug cavity 12. The protrusion 19 is configured to contact the mating terminal when it is inserted into the plug cavity 12 to achieve an electrical connection. As shown, the opening 17 divides the sidewall 15 of the plug portion 11 into a plurality of elongated strips supporting the insertion port 18 of the plug cavity 12. These elongated strips form a cage-like plug cavity 12. When the mating terminal is inserted into the plug cavity 12, these elongated strips surround the mating terminal, and the protrusions 19 on the strips contact the mating terminal to form an electrical connection. This arrangement increases the number of contact points, which is beneficial for providing electrical performance of the connection.

[0032] As shown in the figure, the protrusion 19 of the side wall 15 of the insertion portion 11 and the curved portion 16 of the cantilever 13 are offset along the axial direction of the insertion cavity 12. This arrangement makes the insertion and extraction forces more stable when the mating terminals are inserted into and removed from the insertion cavity 12, which helps to reduce the operating force of the connector.

[0033] The protrusion 19 of the sidewall 15 of the insertion portion 11 is formed by the sidewall 15 being recessed toward the center of the insertion cavity 12. During the manufacturing of the conductive terminal 1, the protrusion can be formed by bending the elongated strip that forms the sidewall 15 through stamping, thus simplifying the manufacturing process.

[0034] The insertion portion 11 of the conductive terminal 1 is a single piece. During the manufacturing process, the conductive sheet is directly cut and stamped, and finally wound to form the insertion portion 11.

[0035] The cantilever 13 is a conductive spring, and the sidewall 15 is conductive. As shown in the figure, the cantilever 13 is a spring cut from the sidewall 15 of the insertion part 11.

[0036] Those skilled in the art will know that there are multiple cantilever arms 13 arranged circumferentially around the insertion cavity 12, and multiple protrusions 19 of the sidewall 15 arranged circumferentially around the insertion cavity 12. In this embodiment, there are two cantilever arms 13; however, the number of cantilever arms 13 is not limited to this and can be more or fewer.

[0037] Figure 3 This is a perspective view of a conductive terminal assembly 2 according to an exemplary embodiment of the present invention.

[0038] As shown in the figure, the conductive terminal assembly 2 according to this utility model includes a sleeve 21 and the aforementioned conductive terminal 1, wherein the sleeve 21 is sleeved outside the insertion portion 11 of the conductive terminal 1 and fixed to the insertion portion 11. For example, the sleeve 21 may be the sleeve 21 portion of a light body protective sleeve or a lock gun protective sleeve.

[0039] The conductive terminal assembly 2 further includes a locking structure 22 that fixes the sleeve 21 to the insertion portion 11. The locking structure 22 includes a protrusion 23 protruding from one side wall of the insertion portion 11 and the side wall of the sleeve 21 toward the other. The protrusion 23 engages with the other side wall of the insertion portion 11 and the side wall of the sleeve 21 to suppress movement of the sleeve 21 relative to the insertion portion 11. Figure 3 In the illustrated embodiment, the protrusion 23 protrudes from the side wall of the sleeve 21 toward the side wall of the insertion portion 11.

[0040] According to another embodiment of the present invention, a connector is provided, including a housing and a conductive terminal assembly 2 fixed within the housing, wherein the conductive terminal assembly 2 is the aforementioned conductive terminal assembly 2.

[0041] The advantages of the conductive terminal according to this invention are that, in the aforementioned exemplary embodiments of this invention, a cantilever-like spring contact is added to the existing simply supported beam of the circular terminal, and the contacts of the spring contact and the contacts of the simply supported beam are offset from each other along the axial direction of the terminal, resulting in more stable insertion and extraction force performance. Under the same conditions, the clamping force generated by the cantilever beam varies less with the interference fit. The tolerance requirements for component manufacturing are relatively fewer, making manufacturing simpler. Furthermore, a greater number of contact points is beneficial to the electrical performance of the connector. The axially offset contact point design helps reduce the connector operating force. The circular terminal of this invention can be used alone or in conjunction with a light-body protective sleeve or a locking gun protective sleeve to meet different application needs.
