AI Technical Summary
Traditional electrical connectors are prone to deformation and wear when multiple rows of pins are inserted and removed in high-density layouts, leading to poor contact. Furthermore, existing improvement solutions cannot effectively reduce the peak insertion and extraction force or increase the complexity of the model.
The system employs alternating layers of partition one and partition two, with two sets of bent pins of the same model arranged in a staggered manner in space. The first end is flush, while the second end is staggered at different heights. By alternating the layers of partitions, the pin ends are staggered, thus dispersing the insertion and extraction force and reducing the insertion and extraction resistance.
It simplifies the pin design, reduces peak insertion and extraction forces, extends connector lifespan, and simplifies production, processing, and inventory management.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, and more specifically, to an electrical connector for high-fidelity communication cables with staggered pin arrangements. Background Technology
[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.
[0003] As electronic devices trend towards miniaturization and high density, the structural design and performance optimization of electrical connectors, as key interconnection components, become particularly important. Traditional electrical connectors typically employ multiple rows of straight or bent pins arranged in parallel for signal transmission. However, in high-density layouts, the following problems arise: when multiple rows of pins are inserted or withdrawn simultaneously, the insertion and extraction forces reach their peak instantaneously, easily leading to pin deformation, socket wear, and even poor contact, affecting the connector's mechanical life and electrical performance. To address these issues, some improvements have been implemented in existing technologies, such as using a stepped arrangement to distribute the insertion and extraction forces. However, these solutions usually require custom-made pins of different specifications, inevitably increasing the number of pin types. While some staggered arrangement designs can reduce insertion and extraction forces, they may cause misalignment of pin ends, increasing assembly difficulty. Therefore, a new type of electrical connector structure is urgently needed that can reduce the number of pin types while optimizing insertion and extraction mechanical performance and ensuring reliable connections in high-density layouts.
[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

[0006] To address the aforementioned technical problems, this utility model provides an electrical connector for high-fidelity communication cables with staggered pin arrangements. The connector includes a base and multiple partitions disposed within the base. Each partition includes multiple first partitions and multiple second partitions, which are alternately stacked along a front-to-back direction. The front surface of each first partition is fitted with a first group of bent pins composed of multiple bent pins of different models; the front surface of each second partition is fitted with a second group of bent pins composed of multiple bent pins of different models. The first and second groups of bent pins are identical in model. The first end of the first set of bent pins extends from the side edge of partition one and is flush with the end. The second end of the first set of bent pins extends from the upper edge of partition one and is flush with the end. The first end of the second set of bent pins extends from the side edge of partition two and is flush with the end.

The bent pin includes a first segment and a second segment that are perpendicular to each other, and a bent segment connecting the first segment and the second segment. The end of the first segment is the first end, and the end of the second segment is the second end. The first segment of the bent pin is installed in the first mounting groove and extends outward from the first mounting groove. The second segment of the bent pin is installed in the corresponding second mounting groove and extends outward from the second mounting groove. The first mounting grooves of the partition one and the first mounting grooves of the partition two are arranged alternately in the up-down direction.

[0014] This invention discloses a high-fidelity communication cable connector with staggered pin arrangement. By alternately stacking two partitions, and installing a first and second set of bent pins of the same type but with a staggered spatial arrangement on their front surfaces, the first ends (side edge protrusions) of the two sets of pins remain flush, while the second ends (upper edge protrusions) have a height difference in the vertical direction. Since the two sets of bent pins are identical in type, the staggered arrangement of the pin ends can be achieved simply by stacking the partitions, eliminating the need for additional designs of bent pins of different lengths. This reduces the complexity of the pin types and simplifies production and inventory management. Furthermore, the staggered arrangement allows the second ends of the bent pins to make contact in stages, effectively dispersing the peak force during insertion and removal, reducing insertion and removal resistance, and extending the connector's service life.

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0028] like Figure 1 and 2 As shown, this application discloses an electrical connector for a high-fidelity communication cable with staggered pin arrangements. The electrical connector includes a base 1 and multiple partitions disposed within the base 1.
[0029] like Figure 4As shown, the partition includes multiple partition 3 and multiple partition 4, which are alternately stacked in the front-to-back direction. A first group of bent pins 5, composed of multiple bent pins of different models, is installed on the front surface of partition 3; a second group of bent pins 6, composed of multiple bent pins of different models, is installed on the front surface of partition 4. The first group of bent pins 5 and the second group of bent pins 6 are of the same model. The first end 51 of the first group of bent pins 5 extends from the side edge of partition 3 and is flush with the end. The second end 52 of the bent pin 5 extends from the upper edge of the partition 3 and is flush with the end; the first end of the second group of bent pins 6 extends from the side edge of the partition 4 and is flush with the end; the second end of the second group of bent pins 6 extends from the upper edge of the partition 4 and is flush with the end; the first group of bent pins 5 and the second group of bent pins 6 are aligned one-to-one in the front-back direction and are arranged alternately in the vertical direction; the first end 51 of the first group of bent pins 5 is flush with the first end of the second group of bent pins 6; the second end 52 of the first group of bent pins 5 and the second end of the second group of bent pins 6 are arranged alternately in the vertical direction.
[0030] like Figure 5 and 6 As shown, the front surface of the partition is provided with multiple first mounting grooves 32, 42 extending in the left-right direction and multiple second mounting grooves 31, 41 extending in the up-down direction. The multiple first mounting grooves 32, 42 are arranged in the up-down direction, and the multiple second mounting grooves 31, 41 are arranged in the left-right direction. The first mounting grooves 32, 42 and the second mounting grooves 31, 41 are arranged in a one-to-one correspondence. Figure 10 As shown, the bent pin includes a first segment 53 and a second segment 54 that are perpendicular to each other, and a bent segment 55 connecting the first segment 53 and the second segment 54. The end of the first segment 53 is a first end 51, and the end of the second segment 54 is a second end 52. Figure 7As shown, the first segment 53 of the bent pin is installed in the first mounting slots 32, 42 and extends outward from the first mounting slots 32, 42; the second segment 54 of the bent pin is installed in the corresponding second mounting slots 31, 41 and extends outward from the second mounting slots 31, 41. The first mounting slots 32 of the partition 1 3 and the first mounting slots 42 of the partition 2 4 are arranged alternately vertically; the second mounting slots 31 of the partition 1 3 and the second mounting slots 41 of the partition 2 4 are aligned front to back. By alternately stacking the partition 1 3 and the partition 2 4, and installing the same type of first and second sets of bent pins 6 with staggered spatial arrangement on their front surfaces, the first ends 51 (side edge protruding ends) of the two sets of pins remain flush, while the second ends 52 (upper edge protruding ends) form a height difference in the vertical direction. Since the two sets of bent pins have the same model number, the staggered arrangement of the pin ends can be achieved simply by overlapping the partitions. There is no need to design bent pins of different lengths, which reduces the model complexity of the pins and simplifies production, processing and inventory management.
[0031] like Figure 1 and 2 As shown, the base 1 further includes a positioning plate, which has multiple first through holes, through which the first end 51 of the bent pin protrudes. The base 1 also includes a protective plate, which has multiple second through holes 71, through which the second end 52 of the bent pin protrudes.
[0032] The second end of the second group of bent pins 6 is higher in height than the second end of the first group of bent pins 5. The protective plate 7 can move up and down along the insertion direction. When the protective plate 7 is in the upper limit position, the second end 52 of the bent pin is located in or extends out of the second through hole 71. Figure 3 As shown, in a preferred embodiment, when the guard plate 7 is in its upper limit position, the second end of the second set of bent pins 6 extends from the second through hole 71, and the second end of the first set of bent pins 5 is located within the second through hole 71. During insertion and removal operations, the second end of the second set of bent pins 6 can be contacted individually first, and then the second end of the first set of bent pins 5 can be exposed by lowering the position of the guard plate, achieving phased conduction and avoiding simultaneous force on all bent pins, thus reducing the peak insertion and removal force. The partition is also provided with front and rear through positioning holes 33, 43, and the positioning holes 33, 43 of each partition are coaxially aligned and fixedly connected by positioning rivets 8 inserted therethrough. This fixing method can enhance the mechanical strength of the partition stack and prevent partition displacement caused by vibration or insertion and removal force.
