[0039] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application, some technical features well known in the art are not described.

[0040] It should be understood that the present application can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. On the contrary, providing these embodiments will make the disclosure thorough and complete and fully convey the scope of the present application to those skilled in the art. In the accompanying drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity. The same reference numerals throughout represent the same elements.

[0041] It should be understood that when an element or layer is referred to as "on ...", "adjacent to ...", "connected to" or "coupled to" other elements or layers, it can be directly on, adjacent to, connected to or coupled to other elements or layers, or there can be intervening elements or layers. On the contrary, when an element is referred to as "directly on ...", "directly adjacent to ...", "directly connected to" or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. can be used to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the teachings of the present application, the first element, component, region, layer or part discussed below can be represented as a second element, component, region, layer or part.

[0042] Spatially relative terms such as "under," "below," "below," "under," "above," "above," etc., may be used herein for ease of description to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, the spatially relative terms are intended to include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, then the elements or features described as "under other elements" or "under" or "under" will be oriented as "on" the other elements or features. Therefore, the exemplary terms "under" and "under" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or other orientations) and the spatial descriptors used herein are interpreted accordingly.

[0043] The purpose of the terms used herein is only to describe specific embodiments and is not intended to be limiting of the present application. When used herein, the singular forms "one", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates otherwise.

When used herein, the term "and / or" includes any and all combinations of the relevant listed items.

[0044] In actual use, the linear integrated PIN pin may experience excessive mechanical stress on the PIN pin body due to deformation caused by mechanical vibration or temperature change, which may cause the PIN pin to fall off and eventually fail under long-term service conditions.

[0045] The S-shaped integrated PIN has certain improvements in stress release in the X, Y or Z direction, but it cannot release stress on the S-shaped surface and perpendicular to the S surface at the same time, that is, it cannot release stress in the X, Y and Z directions at the same time. Long-term service can also easily lead to PIN failure.

[0046] In order to solve at least one of the above technical problems, the present application provides a PIN needle, which includes a needle seat, a needle body and a needle head connected in sequence, wherein the needle body includes a plurality of wire parts, and the plurality of wire parts are arranged in a bundle.

[0047] According to the PIN needle of the present application, by designing the needle body of the PIN needle to include a plurality of wire parts and the plurality of wire parts are arranged in a bundled structure, the PIN needle can simultaneously achieve stress release in three directions of X, Y and Z, thereby reducing the failure risk of the PIN needle and improving the reliability of the PIN needle.

[0048] In order to thoroughly understand the present application, detailed steps and structures will be presented in the following description to illustrate the technical solution proposed by the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0049] Embodiment 1

[0050] Reference below Figure 1 A PIN needle according to an embodiment of the present application is described. The PIN needle comprises a needle seat 110, a needle body 120 and a needle head 130 connected in sequence, wherein the needle body 120 comprises a plurality of wire parts 120, and the plurality of wire parts 120 are arranged in a bundle.

[0051] Specifically, the multiple wire portions 120 are arranged in a cluster, which means that the multiple wire portions 120 are combined together in a certain arrangement, for example, the multiple wire portions 120 are arranged together in parallel. Since there is a certain amount of movable space between the wire portions 120, it has better flexibility than an integrated PIN needle, so that the PIN needle can simultaneously achieve stress release in the X, Y and Z directions, thereby reducing the failure risk of the PIN needle and improving the reliability of the PIN needle.

[0052] Moreover, by designing the needle body 120 of the PIN needle to include a plurality of wire portions 120 and the plurality of wire portions 120 are arranged in a bundled structure, each wire portion 120 in the needle body 120 can withstand stress individually. Compared with an integrated PIN needle, the PIN needle in this embodiment can withstand greater stress.

[0053] In addition, when the needle body 120 is subjected to external force, each wire portion 120 in the needle body 120 can share the external force, reducing the stress on a single wire portion 120, thereby reducing the risk of breakage of the needle body 120. Even if some wire portions 120 are damaged, the other wire portions 120 can still continue to function, thereby extending the service life of the needle body 120.

[0054] In some embodiments, the cross-section of the wire portion 120 may be a regular shape or an irregular shape, which is not limited. A regular wire portion 120 refers to a wire portion 120 having a regular cross-section, such as a circle, a triangle, a rectangle, a regular polygon, etc., and an irregular wire portion 120 refers to a wire portion 120 having an irregular cross-section. For each of the plurality of wire portions 120, a wire portion 120 having the same cross-section may be provided, or wire portions 120 having different cross-sections may be provided according to the functional requirements of different wire portions 120, without being limited to a wire portion 120 having a single cross-section to meet the performance requirements of the entire PIN needle.

[0055] In some embodiments, the wire portion 120 can be linear or spiral or any other suitable form. Taking the linear wire portion as an example, the linear wire portion can be neatly arranged together, reasonably arranged and laid out, such as parallel arrangement or close fitting arrangement. In some cases, the space can be fully utilized to reduce the space volume occupied by the bundled cables, especially in an environment with limited space. Taking the spiral wire portion as an example, the spiral wire portion itself has good flexibility. In the bundled setting, even if it is bent, squeezed or stretched to a certain extent, the spiral wire portion is not easy to break or damage, and can adapt to complex use environments; moreover, the spiral wire portion can be stretched and contracted within a certain range, playing a role in stress buffering and adaptation. For each of the multiple wire portions 120, it can be set to the same form of wire portion 120, or it can be set to have wire portions 120 with different forms according to the functional requirements of different wire portions 120. It is not necessary to be limited to one shape of wire portion 120 to meet the performance requirements of the entire PIN needle.

[0056] In some embodiments, the plurality of wire portions 120 may be arranged together in any suitable manner to form a bundled arrangement. For example, the axes of the plurality of wire portions 120 may be parallel to each other, so that the plurality of wire portions 120 are arranged parallel to each other.

[0057] In some embodiments, the plurality of wire portions 120 may be spaced apart from each other, wherein the distance of the spaced apart arrangement may be set according to actual conditions, and this is not limited. Of course, the present application does not exclude the situation where at least two of the plurality of wire portions 120 may contact each other.

[0058] In some embodiments, the PIN needle in this embodiment can be made of metal or any other suitable conductive material, which is not limited. Moreover, the needle seat 110, the needle body 120 and the needle head 130 can be made of the same material or different materials, and for each of the multiple wire parts 120 in the needle body 120, different raw materials can be selected according to the functional requirements of different wire parts 120, and it is not necessary to be limited to one material to meet the performance requirements of the entire needle body 120.

[0059] In some embodiments, Figure 1 As shown, the needle head 130 of the PIN needle is constructed as a tapered structure, that is, the cross-sectional area of ​​the needle head 130 gradually decreases in the direction away from the needle seat 110. By constructing the needle head 130 of the PIN needle as a tapered structure that gradually becomes thinner, the PIN needle can be inserted more smoothly when inserted into a jack, socket or other connection part, reducing the insertion resistance. This is very important for application scenarios that require frequent plugging and unplugging, which can reduce the difficulty of operation and improve work efficiency. In addition, the tapered design allows the needle head 130 to have a certain self-guiding effect during the insertion process. Even if the position of the jack deviates slightly, the needle head 130 can gradually adjust the direction under the guidance of the cone and accurately insert it into the target position, reducing the risk of damage caused by inaccurate alignment.

[0060] In some embodiments, Figure 1 As shown, the needle body 120 also includes a first wire portion combining end 121 and a second wire portion combining end 122. The first ends of the plurality of wire portions 120 are connected to the needle seat 110 via the first wire portion combining end 121, and the second ends of the plurality of wire portions 120 are connected to the needle head 130 via the second wire portion combining end 122.

[0061] The first wire portion joint end 121 may form a transition between the wire portion 120 and the needle seat 110 , and the second wire portion joint end 122 may form a transition between the wire portion 120 and the needle head 130 , thereby improving the strength of the needle body 120 .

[0062] In some embodiments, Figure 1As shown, the cross-sectional area of ​​the needle hub 110 is larger than the cross-sectional area of ​​the needle body 120. On the one hand, the larger needle hub 110 can serve as an obvious visual and physical reference point, making the installation process more accurate and easier. At the same time, the larger size of the needle hub 110 also facilitates precise positioning and grasping in automated installation equipment, which is suitable for automated assembly processes in large-scale production. On the other hand, the larger cross-sectional area of ​​the needle hub 110 can act as a limiter to prevent the PIN needle from being over-inserted during the insertion process and damaging the internal circuit or other components. On the other hand, in some high-power or high-frequency applications, the PIN pin may generate a certain amount of heat. The needle hub 110 with a larger cross-sectional area has a larger surface area and can better dissipate the heat, which helps to reduce the operating temperature of the PIN pin and improve its performance and reliability. On the other hand, when the PIN needle is subjected to external force, such as pulling force during insertion and removal or vibration during use, the needle seat 110 with a larger cross-sectional area can better disperse the stress, which can reduce the stress concentration on the needle body 120 and the needle head 130, and reduce the possibility of breakage of the needle body 120 or the needle head 130, thereby extending the service life of the PIN needle.

[0063] Embodiment 2

[0064] Reference below Figure 2 A method for manufacturing a PIN needle according to an embodiment of the present application may include the following steps:

[0065] Step S21, providing a plurality of wires 101;

[0066] Step S22, arranging the plurality of wires 101 in a bundle;

[0067] Step S23, combining the first ends of the plurality of wires 101 arranged in a bundle to form a first wire combined end 141, and combining the second ends of the plurality of wires 101 arranged in a bundle to form a second wire combined end 142;

[0068] In step S24 , a portion of the first wire connecting end 141 is processed into the needle seat 110 , and a portion of the second wire connecting end 142 is processed into the needle head 130 .

[0069] Specifically, the multiple wires 101 are arranged in a cluster, which means that the multiple wires 101 are combined together in a certain arrangement, for example, the multiple wires 101 are arranged together in parallel. Since there is a certain amount of movable space between the wires 101, it has better flexibility than an integrated PIN needle, so that the PIN needle can simultaneously release stress in the X, Y and Z directions, thereby reducing the failure risk of the PIN needle and improving the reliability of the PIN needle.

[0070] In some embodiments, Figure 3A In the embodiment, the wire 101 provided can be made of metal or any other suitable conductive material, and there is no limitation on this. For each of the multiple wires 101, the same material can be selected, or different raw materials can be selected according to the functional requirements of different wires 101, and there is no need to be limited to one material to meet the performance requirements of the entire PIN needle.

[0071] In some embodiments, the provided wire 101 may be a regular wire or an irregular wire, which is not limited. A regular wire refers to a wire 101 having a regular cross-section, such as a circle, a triangle, a rectangle, a regular polygon, etc., and an irregular wire refers to a wire 101 having an irregular cross-section. For each of the plurality of wires 101, a wire 101 having the same cross-section may be selected, or a wire 101 having different cross-sections may be selected according to the functional requirements of the different wires 101. It is not necessary to be limited to a wire 101 having a single cross-section to meet the performance requirements of the entire PIN needle.

[0072] In some embodiments, the provided wire 101 can be a straight wire 101, a spiral wire 101 or any other suitable form. Taking the straight wire 101 as an example, the straight wire 101 can be neatly arranged together, and a reasonable arrangement and layout can be performed, such as parallel arrangement or close arrangement. In some cases, the space can be fully utilized to reduce the space volume occupied by the bundled cable, especially in an environment with limited space. Taking the spiral wire 101 as an example, the spiral wire 101 itself has good flexibility. In the bundled setting, even if it is bent, squeezed or stretched to a certain extent, the spiral wire 101 is not easy to break or damage, and can adapt to complex use environments; moreover, the spiral wire 101 can be stretched and contracted within a certain range, playing a role in stress buffering and adaptation. For each of the multiple wires 101, a wire 101 of the same form can be selected, or a wire 101 with different forms can be selected according to the functional requirements of different wires 101. It is not necessary to be limited to a wire 101 of one shape to meet the performance requirements of the entire PIN needle.

[0073] In some embodiments, the provided plurality of wires 101 may be arranged and sorted in any suitable manner so that the plurality of wires 101 are arranged in a bundle.

[0074] For example, Figure 4 As shown, a limiting fixture 200 is shown, and a plurality of holes 201 for placing wires 101 are arranged in the limiting fixture 200. When in use, as Figure 3BAs shown, each of the plurality of wires 101 can be respectively inserted into a wire 101 placement hole 201 in the limiting fixture 200, so that the plurality of wires 101 are arranged in a bundle.

[0075] In some embodiments, any suitable method can be adopted to combine the first ends of the plurality of wires 101 arranged in a bundle into the first wire combined end 141, such as welding, adhesive connection, cold extrusion connection, etc. Among them, the welding method can include laser welding, ultrasonic welding, arc welding, etc., which are not limited. Similarly, any suitable welding method mentioned above can also be adopted to combine the second ends of the plurality of wires 101 arranged in a bundle into the second wire combined end 142, which is also not limited.

[0076] It should be noted that when the first ends and the second ends of the plurality of wires 101 arranged in a bundle are combined, the order of combining is not limited. For example, the first ends of the plurality of wires 101 arranged in a bundle may be combined first, and then the second ends of the plurality of wires 101 arranged in a bundle may be combined, or the second ends of the plurality of wires 101 arranged in a bundle may be combined first, and then the first ends of the plurality of wires 101 arranged in a bundle may be combined, or the first ends and the second ends of the plurality of wires 101 arranged in a bundle may be combined at the same time.

[0077] For example, Figure 3C The schematic diagram shows that the first ends of the plurality of wires 101 arranged in a bundle are combined into a first wire combined end 141, and the second ends are combined into a second wire combined end 142. After the first ends of the plurality of wires 101 arranged in a bundle are combined into the first wire combined end 141, and the second ends of the plurality of wires 101 arranged in a bundle are combined into the second wire combined end 142, the remaining wires 101 between the first wire combined end 141 and the second wire combined end 142 can be referred to as a wire portion 120.

[0078] In some embodiments, any suitable method may be adopted to process part of the first wire joint end 141 into the needle seat 110. For example, part of the first wire joint end 141 may be processed into the needle seat 110 by cold heading process. The cold heading process is a pressure processing process. At room temperature, the plasticity of the material is utilized and a cold heading die is used to apply pressure to the blank to cause plastic deformation, thereby obtaining a part with the desired shape, size and performance. Figure 3E As shown, through the cold heading process, part of the first wire connecting end 141 can be processed into a needle seat 110 with a cross-sectional area larger than the needle body 120 , and the remaining unprocessed first wire connecting end 141 is the first wire portion connecting end 121 of the needle body 120 .

[0079] In some embodiments, any suitable method may be used to process part of the second wire joint end 142 into the needle 130. For example, part of the second wire joint end 142 may be processed into the needle 130 by CNC process. CNC (Computer Numerical Control) process is a method of controlling the movement and processing of a machine tool by using digital information. Figure 3D As shown, part of the second wire connecting end 142 can be processed into a needle head 130 with a conical structure through CNC technology, and the remaining unprocessed first wire connecting end 141 is the second wire connecting end 122 of the needle body 120.

[0080] It should be noted that when processing part of the first wire joint end 141 into the needle seat 110 and processing part of the second wire joint end 142 into the needle head 130, the processing sequence is not limited. For example, part of the first wire joint end 141 can be processed into the needle seat 110 first, and then part of the second wire joint end 142 can be processed into the needle head 130, or part of the second wire joint end 142 can be processed into the needle head 130 first, and then part of the first wire joint end 141 can be processed into the needle seat 110, or part of the first wire joint end 141 can be processed into the needle seat 110 and part of the second wire joint end 142 can be processed into the needle head 130 at the same time.

[0081] In summary, according to the PIN needle and the manufacturing method thereof in the embodiments of the present application, by designing the needle body of the PIN needle to include a plurality of wire parts and the plurality of wire parts are bundled and arranged in a structure, the PIN needle can simultaneously achieve stress release in the three directions of X, Y and Z, thereby reducing the failure risk of the PIN needle and improving the reliability of the PIN needle.
