Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically, to a conductive floating connection terminal. Background Technology

[0002] Floating connectors are widely used in electronic equipment to absorb installation errors and accommodate displacement between PCB boards. Existing floating connectors typically include a housing, a first spring, a moving part, and a second spring. The first spring is located within the housing, the moving part can move relative to the housing and is connected via the first spring, and the second spring is located within the moving part for mating. During current conduction, the current must sequentially pass through multiple contact interfaces between the housing and the first spring, the first spring and the moving part, and the second spring and the moving part. Each contact interface has contact resistance; the increased number of transitions leads to an increase in overall resistance, resulting in excessive temperature rise and affecting electrical performance and current-carrying capacity. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a conductive floating connection terminal.

[0004] The present invention discloses a conductive floating connection terminal, comprising: a carrier, a floating component, and a conductive component; The carrier has a floating hole and a first receiving groove. The first receiving groove is opened around the floating hole and the floating hole communicates with the first receiving groove. The floating component is movably disposed in the floating hole and the first receiving groove. The floating component has a second receiving groove, and the conductive component is disposed within the second receiving groove; The conductive element includes a first conductive body and a plurality of second conductive bodies. The first conductive body is disposed in a second receiving groove, and the plurality of second conductive bodies are disposed at the ends of the first conductive body. The plurality of second conductive bodies extend into the first receiving groove, and one side of each second conductive body abuts against the first wall of the first receiving groove. The first conductor has a third receiving groove, and an external conductor is inserted into the third receiving groove so that the outer wall surface of the first conductor abuts against the inner wall surface of the second receiving groove.

[0005] According to one embodiment of the present invention, a plurality of second conductors are distributed at intervals along the end edges of the first conductor.

[0006] According to one embodiment of the present invention, the second conductor has an arc surface that abuts against the first wall surface of the first receiving groove.

[0007] According to one embodiment of the present invention, the second conductor further has a bending portion, which is disposed at the end of the second conductor near the first conductor, and the side of the bending portion away from the arc surface abuts against the end of the floating member.

[0008] According to one embodiment of the present invention, the first conductor and a plurality of second conductors are integrally structured and are made of a material with high conductivity and high yield strength.

[0009] According to one embodiment of the present invention, it further includes a fastener that abuts against the first conductor and a plurality of second conductors, thereby fixing the conductor to the floating member.

[0010] According to one embodiment of the present invention, the floating component includes a first floating body and a second floating body. The first floating body is movably disposed in a floating hole, a second receiving groove is formed in the first floating body, and the second floating body protrudes from the outer surface of the first floating body and is movably disposed in the first receiving groove.

[0011] According to one embodiment of the present invention, it further includes an elastic element, which protrudes from the second wall surface of the floating element, and the side of the second conductor away from the first wall surface abuts against the elastic element.

[0012] According to one embodiment of the present invention, the floating member further has a fourth receiving groove formed on the second wall surface, and the elastic member is disposed in the fourth receiving groove.

[0013] According to one embodiment of the present invention, the first receiving groove has a third wall surface facing the first wall surface, and a lifting body is provided protruding from the third wall surface. The floating member also has a fourth wall surface, which is in contact with the lifting body.

[0014] The beneficial effects of the present invention are as follows: the current conduction mainly occurs between the carrier, the second conductor and the first conductor, and part of the current conduction occurs between the carrier, the floating member and the first conductor. It can be seen that the number of contact interfaces and transitions involved in the current conduction is reduced, which helps to reduce the resistance value, avoid the problem of excessive temperature rise, and thus ensure the electrical performance and current carrying capacity of the conductive floating connection terminal.

[0017] The following drawings disclose several embodiments of the present invention. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0019] Example 1 like Figures 1-3 As shown, Figure 1A three-dimensional structural diagram of a conductive floating connection terminal; Figure 2 A cross-sectional view of a conductive floating connection terminal; Figure 3 This is a schematic diagram showing the disassembled structure of a conductive floating connection terminal. The conductive floating connection terminal includes a carrier 1, a floating component 2, and a conductive component 3. The floating component 2 is movably mounted on the carrier 1, and the conductive component 3 is mounted on the floating component 2 and in contact with the carrier 1. The carrier 1, floating component 2, and conductive component 3 are all made of conductive material. There are two current conduction paths: one is a direct current conduction between the conductive component 3 and the carrier 1; the other is a current conduction between the conductive component 3, the floating component 2, and the carrier 1.

[0020] The support member 1 includes a first housing 14 and a second housing 15, which are connected. The first housing 14 is provided with a floating hole 11. After the first housing 14 and the second housing 15 are connected, a first receiving groove 12 is formed inside. The first receiving groove 12 communicates with the floating hole 11 and is formed around the floating hole 11. The floating member 2 is movably disposed in the floating hole 11 and the first receiving groove 12. Specifically, the first housing 14 and the second housing 15 can be connected by riveting.

[0021] The floating component 2 includes a first floating body 23 and a second floating body 24. The second floating body 24 is disposed around the outer surface of the first floating body 23 and protrudes from the outer surface of the first floating body 23. The first floating body 23 is movably disposed in the floating hole 11, and the second floating body 24 is movably disposed in the first receiving groove 12.

[0022] The first floating body 23 is provided with a second receiving groove 21, and the conductive member 3 is disposed in the second receiving groove 21. Specifically, the second receiving groove 21 is located in the floating hole 11, and the opening direction of the second receiving groove 21 and the floating hole 11 is the same.

[0023] The second floating body 24 has a fourth wall 26, and the first receiving groove 12 has a third wall 122 that is directly opposite to the first wall 121. The fourth wall 26 and the third wall 122 are in contact so that current can be conducted between them.

[0024] Please refer to the following: Figure 4 , Figure 4This is a three-dimensional structural diagram of the conductive element 3. The conductive element 3 includes a first conductive body 31 and a plurality of second conductive bodies 32. The first conductive body 31 is disposed in the second receiving groove 21, and the plurality of second conductive bodies 32 are disposed at the ends of the first conductive body 31. The plurality of second conductive bodies 32 are distributed at intervals along the edges of the ends of the first conductive body 31. The plurality of second conductive bodies 32 are located outside the second receiving groove 21, and all of the plurality of second conductive bodies 32 extend into the first receiving groove 12. One side of each second conductive body 32 abuts against the first wall surface 121 inside the first receiving groove 12 to realize the current conduction between the carrier 1 and the conductive element 3.

[0025] The first conductor 31 is provided with a third receiving groove 311 to facilitate the insertion of an external conductor. When the external conductor is inserted into the third receiving groove 311, the outer wall surface of the first conductor 31 expands outward and abuts against the inner wall surface of the second receiving groove 21, so that current can be conducted between the external conductor, the first conductor 31, and the floating member 2. Specifically, the external conductor can be a pin or other components that need to be electrically connected.

[0026] The end of the second conductor 32 away from the first conductor 31 is provided with an arc surface 321. The arc surface 321 abuts against the first wall surface 121 in the first receiving groove 12. By setting the arc surface 321, the effective contact area between the second conductor 32 and the second housing 15 can be increased, thereby improving the current conduction effect between the second conductor 32 and the second housing 15.

[0027] The second conductor 32 has a bent portion 322 at its end near the first conductor 31. The side of the bent portion 322 away from the first wall surface 121 is in contact with the end of the first floating body 23. The bent portion 322 improves the bending performance of the entire second conductor 32, preventing the entire conductor 32 from being crushed due to prolonged stress on the curved surface 321. Furthermore, the bent structure of the bent portion 322 provides a pressing force to the curved surface 321 against the first wall surface 121, which is beneficial for improving current conduction. Additionally, the bent structure of the bent portion 322 enhances its contact with the end of the first floating body 23. In this embodiment, the structure of each second conductor 32 is identical, and will not be discussed in detail here.

[0028] In practical applications, the first conductor 31 and multiple second conductors 32 are integrated into a single structure, and all are made of highly conductive and high-yield-strength materials, such as copper. The integrated structure of the conductor 3 helps to reduce the number of transfers during current conduction, allowing current to be directly conducted between the carrier 1, the conductor 3, and the external conductor, thereby reducing the resistance of the contact interface and avoiding excessive temperature rise during use.

[0029] Furthermore, the conductive floating connection terminal also includes a fastener 4, which abuts against the first conductor 31 and the second conductor 32. The fastener 4 applies a force to the first conductor 31 and the second conductor 32 to improve the fit between the ends of the first conductor 31 and the second conductor 32 and the first floating body 23, making the connection between the conductor 3 and the floating body 2 stable. When the floating body 2 moves, the conductor 3 can move with it, ensuring that the conductor 3 and the floating body 2 fit tightly together, avoiding a decrease in contact effect due to relative movement, which would affect the current conduction efficiency. In this embodiment, the cross-section of the fastener 4 is "L"-shaped, with one part abutting against the first conductor 31 and the other part abutting against the second conductor 32.

[0030] In summary, current conduction mainly occurs between the carrier 1, the second conductor 32, and the first conductor 31, while some current conduction occurs between the carrier 1, the floating component 2, and the first conductor 31. It can be seen that reducing the number of contact interfaces and transitions involved in current conduction helps to reduce the resistance value, avoid excessive temperature rise, and thus ensure the electrical performance and current carrying capacity of the conductive floating connection terminal.

[0031] Example 2 like Figure 5 and Figure 6 As shown, Figure 5 Another three-dimensional structural diagram of a conductive floating connection terminal; Figure 6 This is another cross-sectional view of the conductive floating connection terminal. The difference between this embodiment and Embodiment 1 is that the structure of the first housing 14 is adapted to the usage scenario; in addition, the outer surface of the first housing 14 in this embodiment is also provided with teeth 141 to facilitate subsequent riveting connection with other components.

[0032] Example 3 like Figures 7-9 As shown, Figure 7 This is another three-dimensional structural diagram of a conductive floating connection terminal; Figure 8 This is another schematic diagram of the split structure of the conductive floating connection terminal; Figure 9 This is another cross-sectional view of the conductive floating connection terminal. The differences between this embodiment and Embodiment 1 are as follows: The structures of the first housing 14 and the second housing 15 are adapted to the usage scenario.

[0033] Secondly, the second floating body 24 has a second wall surface 22, which is directly opposite to the first wall surface 121. The conductive floating connection terminal also includes an elastic element 5, which protrudes from the second wall surface 22. The side of the second conductor 32 away from the first wall surface 121 abuts against the elastic element 5. Specifically, the elastic element 5 abuts against the back side of the arc surface 321 on the second conductor 32, where the back side of the arc surface 321 refers to the side away from the first wall surface 121. By providing the elastic element 5, a force can be applied to the second conductor 32, making the arc surface 321 of the second conductor 32 contact the first wall surface 121 more tightly, thereby improving the current conduction effect. It can also reduce the processing accuracy requirements of the conductor 3. Based on the stress deformation characteristics of the elastic element 5 itself, it can provide correction space for the second conductor 32 with processing errors. In this embodiment, the elastic element 5 is made of elastic silicone or rubber material.

[0034] Furthermore, a fourth receiving groove 25 is provided on the second wall surface 22 of the second floating body 24, and the elastic member 5 is disposed in the fourth receiving groove 25. A portion of the elastic member 5 protrudes from the second wall surface 22. The fourth receiving groove 25 helps to fix the position of the elastic member 5 and prevents the position of the elastic member 5 from deviating during use, thereby affecting the current conduction effect.

[0035] Furthermore, a lifting body 13 is provided on the third wall surface 122 of the first receiving groove 12. The lifting body 13 protrudes from the third wall surface 122, and the fourth wall surface 26 of the second floating body 24 abuts against the lifting body 13. When the floating member 2 moves relative to the bearing member 1, the second floating body 24 and the lifting body 13 will also move relative to each other. By setting the lifting body 13, the cold welding phenomenon between the third wall surface 122 and the fourth wall surface 26 due to the influence of high temperature (e.g., 250℃) during later use can be avoided. Since the contact area between the lifting body 13 and the fourth wall surface 26 is smaller than that between the third wall surface 122 and the fourth wall surface 26, even if a cold welding phenomenon occurs between the lifting body 13 and the fourth wall surface 26, the fixed connection between the two can be broken by a relatively small force, so that the two can be restored to a state where they can move relative to each other.

[0036] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
