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 terminals are commonly used in electrical connection scenarios where installation errors need to be compensated for. Existing conventional structures mainly consist of a housing, a first spring, a moving part, and a second spring. The first spring connects the housing and the moving part, ensuring continuous conductivity during the moving part's movement. The second spring is installed inside the moving part and is used to connect to external conductive components such as pins and power strips. However, the current transmission path of this structure requires multiple stages of transition through the second spring, the moving part, and the first spring, resulting in multiple conductive contact interfaces. Each contact interface has inherent contact resistance; the superposition of these multiple resistances significantly increases the overall resistance of the terminal, leading to excessive temperature rise during operation. This can easily cause component aging, contact failure, and significantly reduce the stability and reliability of the electrical connection, shortening the terminal's lifespan. 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 housing, a first support body, and a conductive floating body; The housing has a receiving groove opened along a first direction, and the first support body and the conductive floating body are detachably disposed in the receiving groove, and both the first support body and the conductive floating body can move within the receiving groove. The first support has a support hole opened along the first direction; The conductive floating body includes a carrier body made of conductive material, a plurality of first conductors, and a plurality of second conductors. The carrier body and the plurality of first conductors are all disposed within a support hole. The plurality of first conductors are spaced apart at one end of the carrier body, and the plurality of first conductors and the carrier body together form an insertion hole opened along a first direction. The plurality of second conductors are spaced apart at the other end of the carrier body. The second conductors extend outside the support hole and are located between the inner wall surface of the receiving groove and the outer surface of the first support body. The second conductors abut against the inner wall surface of the receiving groove. When the second conductors are subjected to force in a second direction, the second conductors deform, causing the first distance between the first support body and the inner wall surface of the receiving groove to change. The carrier, multiple first conductors, and multiple second conductors are integrated into a single structure.

[0005] According to one embodiment of the present invention, the second conductor includes a bent portion and a contact portion, one end of the bent portion is connected to a carrier, the other end of the bent portion is connected to the contact portion, and the contact portion extends in a second direction away from the first conductor. The bent portion is located at the end of the first support body, and the contact portion is located between the inner wall surface of the receiving groove and the outer surface of the first support body. The contact portion abuts against the inner wall surface of the receiving groove. When the contact portion is subjected to force in the second direction, the contact portion deforms, causing the first distance between the first support body and the inner wall surface of the receiving groove to change.

[0006] According to one embodiment of the present invention, the contact portion has an arc surface located at the end of the contact portion away from the bent portion in a first direction, and the arc surface is provided to protrude in a direction away from the first conductor in a second direction, and the arc surface abuts against the inner wall surface of the receiving groove.

[0007] According to one embodiment of the present invention, the cross-section of the bent portion taken along the first direction is in the shape of an inverted hook.

[0008] According to one embodiment of the present invention, there are two carriers, which are respectively located at two openings of the support hole in the first direction. The two ends of a plurality of first conductors are respectively connected to the two carriers, and the plurality of first conductors and the two carriers together form an insertion hole opened along the first direction. A portion of the second conductors is connected to one of the two carriers, and another portion of the second conductors is connected to the other of the two carriers.

[0009] According to one embodiment of the present invention, a second support body is further included, which is disposed on the outer surface of the first support body, and the second conductors abut against the inner wall surfaces of the second support body and the receiving groove, respectively.

[0010] According to one embodiment of the present invention, the second support has a support block protruding in a first direction, and the support block abuts against the second conductor.

[0011] According to one embodiment of the present invention, the second support is made of an elastic material.

[0012] According to one embodiment of the present invention, it further includes a fastening solid, which is sleeved on one end of the first support, and one end of the second conductor is located between the fastening solid and the first support, with a second gap between the fastening solid and the inner wall surface of the receiving groove.

[0013] According to one embodiment of the present invention, there are two fasteners, which are respectively fitted onto the two ends of the first support in the first direction.

[0014] The beneficial effects of this invention are as follows: an external conductive component is inserted into the socket and electrically connected to multiple first conductive bodies. Current conduction between the shell and the external conductive component can be achieved through multiple first conductive bodies and multiple second conductive bodies. After the second conductive body is deformed by force, the distance between the first support body and the inner wall of the receiving groove changes, thereby achieving the floating function. It can be seen that by setting the carrier body, multiple first conductive bodies, and multiple second conductive bodies as an integrated structure, the number of current conduction transfers is reduced while ensuring the functions of conductivity and floating. This helps to reduce contact resistance, avoid the problem of excessive temperature rise, greatly reduce the risk of component aging and contact failure, and thus improve the stability and reliability of electrical connections and extend service life.

[0019] like Figures 1-3 As shown, Figure 1 A three-dimensional structural diagram of a conductive floating connection terminal; Figure 2 A schematic diagram showing the disassembled structure of the conductive floating connection terminal; Figure 3 This is a cross-sectional view of a conductive floating connection terminal. The conductive floating connection terminal includes a housing 1, a first support 2, and a conductive floating body 3. The conductive floating body 3 is disposed on the first support 2, and the first support 2 provides support for the conductive floating body 3. The first support 2 and the conductive floating body 3 are detachably disposed within the housing 1, and can move within the housing 1. The conductive floating body 3 abuts against the housing 1. An external conductive component is inserted into the conductive floating body 3, and current conduction between the external conductive component and the housing 1 is achieved through the conductive floating body 3.

[0020] The concepts of first direction and second direction will be used below. The concepts of first direction and second direction will be explained in detail here. In this embodiment, the first direction refers to the X-axis direction and the second direction refers to the Y-axis direction.

[0021] The housing 1 has a receiving groove 11, which is opened in the housing 1 along a first direction. The first support 2 and the conductive floating body 3 are both disposed in the receiving groove 11, and the first support 2 and the conductive floating body 3 can move in the receiving groove 11. The conductive floating body 3 abuts against the inner wall surface of the receiving groove 11 so as to conduct current.

[0022] Please refer to the following: Figure 4 , Figure 4 This is a three-dimensional structural diagram of the first support 2 and the second support 4. The first support 2 has a support hole 21, which is formed along a first direction in the first support 2. The support hole 21 is connected to the receiving groove 11. A portion of the conductive floating body 3 is disposed inside the support hole 21, and the other portion of the conductive floating body 3 extends outside the support hole 21. In this embodiment, the support hole 21 is a through hole.

[0023] Please refer to the following: Figures 5-8 , Figure 5 This is a three-dimensional structural diagram of the conductive floating body 3; Figure 6 Another three-dimensional structural diagram of the conductive floating body 3; Figure 7 This is a front view of the conductive floating body 3; Figure 8 This is a cross-sectional schematic diagram of the conductive floating body 3. The conductive floating body 3 includes a carrier 31, a plurality of first conductors 32 and a plurality of second conductors 33. The plurality of first conductors 32 are spaced apart at one end of the carrier 31 in a first direction, and the plurality of second conductors 33 are spaced apart at the other end of the carrier 31 in the first direction. The carrier 31 and the plurality of first conductors 32 are all located inside the support hole 21, and the plurality of second conductors 33 extend outside the support hole 21. The second conductors 33 are located between the inner wall surface of the receiving groove 11 and the outer surface of the first support 2, and the second conductors 33 abut against the inner wall surface of the receiving groove 11.

[0024] The first support 2 and the inner wall of the receiving groove 11 have a first distance L in the second direction. When the second conductor 33 is subjected to force in the second direction, the second conductor 33 will deform, thereby reducing the first distance L between the first support 2 and the inner wall of the receiving groove 11, so as to realize the floating function of the conductive floating connection terminal.

[0025] Specifically, the carrier 31, the plurality of first conductors 32, and the plurality of second conductors 33 are all made of conductive materials, such as copper. In this embodiment, the carrier 31, the plurality of first conductors 32, and the plurality of second conductors 33 are an integral structure, which helps to reduce the number of current conduction transfers. It should be noted that an integral structure means that the carrier 31, the plurality of first conductors 32, and the plurality of second conductors 33 are all processed from the same material using existing stamping and other processes.

[0026] The carrier 31 and multiple first conductors 32 together form a socket 34. The socket 34 is opened along a first direction and is connected to the receiving groove 11 to facilitate the insertion of external conductive components (such as pins). After the external conductive component is inserted, the multiple first conductors 32 respectively abut against the outer surface of the external conductive component to conduct current. In specific applications, there are two carriers 31, which are spaced apart along the first direction and are located at the two openings of the support hole 21. The two ends of the multiple first conductors 32 in the first direction are respectively connected to the two carriers 31. The two carriers 31 and the multiple first conductors 32 together form the socket 34. The multiple second conductors 33 are divided into two parts. One part of the second conductors 33 is connected to one carrier 31, and the other part of the second conductors 33 is connected to the other carrier 31. Specifically, the two carriers 31, the multiple first conductors 32, and the multiple second conductors 33 are an integral structure.

[0027] Specifically, the cross-section of the carrier 31 in the second direction is annular, and the cross-section of the socket 34 in the second direction is circular.

[0028] There is an angle between the plurality of first conductors 32 and the carrier 31, wherein the angle is acute. Specifically, with a first direction as a reference, the first conductors 32 are inclined.

[0029] The second conductor 33 includes a bent portion 331 and a contact portion 332. The bent portion 331 is located at the port of the first support 2, with one end connected to the carrier 31 and the other end connected to the contact portion 332. The contact portion 332 extends outside the support hole 21 and is located between the inner wall surface of the receiving groove 11 and the outer surface of the first support 2, abutting against the inner wall surface of the receiving groove 11. The contact portion 332 extends in a direction away from the first conductor 32 in the second direction, causing it to protrude beyond the bent portion 331. When the contact portion 332 is subjected to force in the second direction, it will deform, reducing the first distance L between the first support 2 and the inner wall surface of the receiving groove 11.

[0030] In this embodiment, the cross-section of the bent portion 331 in the first direction is in the shape of an inverted hook so that it can be placed at the port of the first support body 2. In addition, this structure can avoid the phenomenon that the second conductor 33 is damaged due to the deformation of the contact portion 332 under force, thereby extending the service life of the conductive floating body 3.

[0031] The contact portion 332 has an arc surface 3321, which protrudes from the surface of the contact portion 332 in the second direction away from the first conductor 32. The arc surface 3321 abuts against the inner wall surface of the receiving groove 11 to increase the positive force between the contact portion 332 and the inner wall surface of the receiving groove 11, thereby improving the current conduction effect between the two.

[0032] Please review Figures 2-4 The conductive floating connection terminal also includes a second support body 4, which is disposed on the outer surface of the first support body 2. The second support body 4 protrudes from the outer surface of the first support body 2 in the second direction. The contact part 332 abuts against the second support body 4 on the side away from the inner wall surface of the receiving groove 11 in the second direction. The second support body 4 can support the contact part 332 and also helps to increase the contact area between the contact part 332 and the inner wall surface of the receiving groove 11, thereby improving the current conduction effect between the contact part 332 and the housing 1.

[0033] Furthermore, the second support body 4 has a support block 41, which protrudes from the outer surface of the second support body 4 in a direction away from the first support body 2 in the second direction. The contact part 332 abuts against the support block 41. By setting the support block 41, the contact area between the contact part 332 and the inner wall surface of the receiving groove 11 can be further increased, and the current conduction effect between the contact part 332 and the housing 1 can be further improved.

[0034] In this embodiment, since the multiple second conductors 33 are divided into two parts and connected to two carriers 31 respectively, the number of support blocks 41 is set to two. The two support blocks 41 are distributed at intervals in the first direction, and the two support blocks 41 respectively abut against the two parts of the second conductors 33.

[0035] Specifically, the second support 4 is made of an elastic material, such as existing silicone or rubber products.

[0036] Please review Figures 1-3 The conductive floating connection terminal also includes a fastener 5, which is sleeved on the outer surface of the end of the first support 2. A bent portion 331 is located between the fastener 5 and the first support 2. The fastener 5 can press the bent portion 331 tightly against the end of the first support 2, thereby making the conductive floating body 3 and the first support 2 firmly connected. In specific applications, there is a second distance S between the outer surface of the fastener 5 and the inner wall of the receiving groove 11. The second distance S determines the range of movement of the conductive floating body 3 and the first support 2 in the receiving groove 11. That is, when the outer surface of the fastener 5 abuts against the inner wall of the receiving groove 11, the conductive floating body 3 and the first support 2 will be unable to move further in that direction.

[0037] In this embodiment, there are two fasteners 5, which are respectively sleeved on both ends of the first support 2. The arrangement of each fastener 5 is as described above and will not be repeated here. The fasteners 5 can be made of stainless steel.

[0038] In summary, the external conductive component is inserted into the socket 34 and electrically connected to multiple first conductors 32. Current conduction between the housing 1 and the external conductive component can be achieved through the multiple first conductors 32 and multiple second conductors 33. After the second conductor 33 is deformed under force, the distance between the first support 2 and the inner wall of the receiving groove 11 changes, thereby achieving the floating function. It can be seen that by setting the carrier 31, multiple first conductors 32 and multiple second conductors 33 as an integrated structure, the number of current conduction transfers is reduced while ensuring the functions of conductivity and floating. This helps to reduce contact resistance, avoid the problem of excessive temperature rise, greatly reduce the risk of component aging and contact failure, thereby improving the stability and reliability of electrical connection and extending service life.

Various modifications and variations can be made to the present invention by those skilled in the art.
