Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connecting terminal. Background Art

[0002] As the core conductive component in the connector, the reed plays a decisive role in the current carrying capacity and temperature rise performance of the connection terminal. Therefore, the design of the reed structure is particularly important.

[0003] For example, a floating terminal consists of a movable component and a fixed component, the electrical connection between which is achieved through a spring. However, the relative movement between the movable and fixed components limits the positive pressure that can be generated between the spring and the components. The magnitude of this positive pressure directly affects the temperature rise of the floating terminal during operation, making it difficult to further reduce the temperature rise during operation.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] like Figure 1-Figure 3 As shown, Figure 1 is a schematic diagram of the three-dimensional structure of the connection terminal; Figure 2 This is a diagram of the split state of the connection terminals; Figure 3 This is a cross-sectional schematic diagram of a connecting terminal. The connecting terminal includes a conductive body 6, a carrier body 4, a spring 10, an adjustment body 5, and a connecting body 7. The conductive body 6 is connected to the carrier body 4, the spring 10 is disposed within the carrier body 4, the adjustment body 5 is connected to the carrier body 4, and the adjustment body 5 and the carrier body 4 are relatively movable. The connecting body 7 extends through the adjustment body 5 and the conductive body 6. During use, current can flow between the conductive body 6, the carrier body 4, the spring 10, and the adjustment body 5.

[0037] The conductive body 6 includes a first conductive plate 61 and a second conductive plate 62. The first conductive plate 61 is sleeved on the outer surface of the carrier 4, and the second conductive plate 62 is located on the bottom surface (underside) of the carrier 4. The connector 7 passes through the adjustment body 5 and the second conductive plate 62. During use, the first conductive plate 61 and the second conductive plate 62 are connected to different components respectively, and the two are connected by the connector 7. Specifically, the first conductive plate 61 and the second conductive plate 62 are both copper busbars.

[0038] Refer to it again Figure 4-Figure 6 As shown, Figure 4 Schematic diagram of the three-dimensional structure of the reed 10; Figure 5 is another schematic diagram of the three-dimensional structure of the reed 10; Figure 6 The figure is a cross-sectional schematic diagram of a spring 10. The spring 10 includes a first contact member 1, multiple first conductive members 2, and multiple second conductive members 3. The first contact member 1 abuts against the adjustment body 5. The multiple first conductive members 2 are spaced apart on one side of the first contact member 1, and the multiple second conductive members 3 are spaced apart on the opposite side of the first contact member 1. During use, when the first contact member 1 is subjected to an external force, it transmits the external force to the multiple first conductive members 2 and the multiple second conductive members 3.

[0039] In a specific application, the first contact member 1 includes a first contact 11 and a second contact 12. One side of the first contact 11 is connected to the second contact 12, and the other side of the first contact 11 is connected to the plurality of first conductive members 2. The second contact 12 is connected to the plurality of second conductive members 3 on a side away from the first contact 11. Furthermore, an angle 13 is formed between the first contact 11 and the second contact 12. It is understood that due to the existence of the angle 13, the longitudinal cross-section of the first contact member 1 has a U-shaped structure, or a structure similar to the mouth of a bell. The connection between the first contact 11 and the second contact 12 is an arc-shaped structure, which abuts the adjustment body 5. Specifically, the opening direction of the first conductive member 2 is the same as the extension direction of the first contact 11, and the opening direction of the second conductive member 3 is the same as the extension direction of the second contact 12. In other words, the extension direction of the first conductive member 2 is the same as the extension direction of the first contact 11, which can also be understood as the angle 13 between the first conductive member 2 and the first contact 11 is 180°. Similarly, the extension direction of the second conductive member 3 is the same as the extension direction of the second contact 12, and the angle 13 between the second conductive member 3 and the second contact 12 is 180°.

[0040] The cross-section of the first contact member 1 can be rectangular, semicircular or annular. In this embodiment, the cross-section of the first contact member 1 is annular, that is, there is a through hole in the middle of the first contact member 1, and the adjustment body 5 will be arranged in the through hole. At the same time, the first conductive member 2 is located outside the ring, and the second conductive member 3 is located in the ring hole.

[0041] Furthermore, a first flat surface 21 is formed at an end of the first conductive member 2 away from the first contact body 11, and the first flat surface 21 abuts against the first receiving groove 42. The provision of the first flat surface 21 can enhance the positive force applied by the first conductive member 2 to the first receiving groove 42. Similarly, a second flat surface 31 is formed at an end of the second conductive member 3 away from the second contact body 12, and the second flat surface 31 abuts against the first receiving groove 42. The provision of the second flat surface 31 can enhance the positive force applied by the second conductive member 3 to the first receiving groove 42.

[0042] In this embodiment, the first contact 1, the first conductive member 2, and the second conductive member 3 are all made of a highly conductive and high-yield-strength material, such as copper. It should also be noted that, although the first contact 11, the second contact 12, the first conductive member 2, and the second conductive member 3 are described above as separate structures, in practice, the first contact 11, the second contact 12, the first conductive member 2, and the second conductive member 3 may be an integrated structure.

[0043] It can be seen that when the connection between the first contact 11 and the second contact 12 is subjected to an external force, the force will be transmitted to the first conductive member 2 and the second conductive member 3, so that the positive force generated by the first conductive member 2 and the second conductive member 3 is enhanced. When the positive force is increased, the impedance generated during the current conduction process is reduced, thereby reducing the temperature rise, which is beneficial to improving the service life and performance during use.

[0044] The carrier 4 is provided with a through hole 41 and a first receiving groove 42. The through hole 41 is opened along the longitudinal direction of the carrier 4. The adjusting body 5 is located in the through hole 41 and the adjusting body 5 can move inside the through hole 41. The first receiving groove 42 is opened around the through hole 41. For example, the cross section of the through hole 41 is circular, and the cross section of the first receiving groove 42 is also circular. At the same time, the first receiving groove 42 is connected to the through hole 41. The first receiving groove 42 has a bottom wall 421 and a side wall 422. The first contact member 1 is located on the surface of the side wall 422 of the first receiving groove 42. At the same time, the first flat surface 21 on the first conductive member 2 abuts against the side wall 422 of the first receiving groove 42. The second flat surface 21 on the second conductive member 3 abuts against the side wall 422 of the first receiving groove 42. The flat surface 31 abuts against the side wall 422 of the first accommodating groove 42. When the adjusting body 5 abuts against the first contact member 1, the first contact member 1 will be deformed in the direction close to the side wall 422 due to the force. At the same time, the force of the first contact member 1 will be transmitted to the first conductive member 2 and the second conductive member 3, and then transmitted to the side wall 422 by the first flat surface 21 of the first conductive member 2 and the flat surface of the second conductive member 3. In this way, the positive force of the first conductive member 2 and the second conductive member 3 acting on the side wall 422 can be greatly increased. During operation, the increase in the positive force will reduce the impedance between each other, thereby reducing the temperature rise. At the same time, it can also improve the current conduction effect.

[0045] In this embodiment, the first contact 1 may be provided on the surface of one side wall 422, or on the surfaces of both side walls 422. Furthermore, the outer surface of the carrier 4 is provided with tooth patterns 43, which facilitate connection with the first conductive plate 61. Preferably, a limiting protrusion 423 is provided on the surface of the side wall 422 of the first receiving groove 42. The limiting protrusion 423 is located opposite the connection between the first contact 11 and the second contact 12. It is understood that since the first and second contacts 11, 12 form a U-shaped or bell-shaped structure after connection, the limiting protrusion 423 is located at the opening thereof. When the first contact 1 is subjected to the force applied by the adjusting body 5, the connection between the first and second contacts 11, 12 will deform toward the limiting protrusion 423. The provision of the limiting protrusion 423 helps prevent the first contact 1 from being crushed and damaged, thereby extending the service life of the first contact 1.

[0046] Referring back to the figure, it can be seen that the length of the first contact 11 projected onto the side wall 422 is greater than the length of the second contact 12 projected onto the side wall 422. This is to make the connection between the first contact 11 and the second contact 12 closer to the adjustment body 5 to prevent the adjustment body 5 from separating from the first contact member 1 during movement.

[0047] The adjustment body 5 includes a connecting tube 51 and a connecting block 52. The connecting tube 51 is located within the through-hole 41, with both ends of the connecting tube 51 extending outside the through-hole 41. The connecting block 52 is annularly disposed on the outer surface of the connecting tube 51 and is movably disposed within the first receiving groove 42, with the first contact member 1 abutting against the connecting block 52. Furthermore, a spacing L is provided between the outer wall surface 521 of the connecting block 52 and the bottom wall 421 of the first receiving groove 42. This spacing L provides space for the connecting block 52 to move. In other words, the connecting tube 51 can move 360° around the center of the through-hole 41 within the through-hole 41 to accommodate deviations at different positions.

[0048] Specifically, the connector 7 is an existing threaded connector, that is, it has a bolt and a nut. The bolt is passed through the interior of the connecting tube 51 (that is, the hollow position), and the bolt also passes through the second conductive plate 62, and then fixed by the threaded connection between the nut and the bolt.

[0049] The conductive body 6, the carrier body 4 and the adjustment body 5 are fixed together by the connecting body 7. When the connection between the first contact body 11 and the second contact body 12 is subjected to the force of the adjustment body 5, this force will be transmitted to the first conductive member 2 and the second conductive member 3, resulting in an increase in the positive pressure exerted by the two on the side wall 422 of the first receiving groove 42. The increase in positive pressure will reduce the impedance encountered by the current during the conduction process, effectively reducing the temperature rise, which is of great benefit to extending the service life and improving the operating performance.

[0050] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
