Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a stamped terminal. Background Technology

[0002] In the wave of digitalization and intelligentization, high-speed connectors have become the key to data transmission, and terminals, as important contact transmission components of high-speed connectors, are receiving increasing attention in their research and development.

[0003] However, terminal technology still faces numerous challenges. Firstly, structurally, the increasing complexity of terminal structures for high transmission rates and multi-functional integration not only complicates design and manufacturing but also necessitates consideration of electromagnetic compatibility, signal integrity, and heat dissipation; deviations in any aspect can degrade electrical performance. Secondly, in terms of arrangement, the high density of connectors leads to smaller terminal spacing and stringent precision requirements. Factors such as the precision of processing equipment, process stability, and material properties make precise terminal installation difficult, resulting in signal crosstalk and poor contact. Finally, in terms of performance, it struggles to meet future demands. Signals are susceptible to interference from resistance and other factors, leading to attenuation and distortion, particularly noticeable at high frequencies. Furthermore, improving current carrying capacity and reducing contact resistance within limited space remains a critical challenge, hindering its application in emerging fields.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: As one aspect of this utility model, a stamped terminal is provided, comprising: a plurality of terminal pins integrally stamped, wherein the plurality of terminal pins are arranged side by side along a first direction and connected by a strip; the terminal pins include: The contact segment is a strip-shaped structure extending along a second direction, wherein the second direction is perpendicular to the first direction; the first end of the contact segment is connected to the material strip; the contact segments of each of the terminal pins along the first direction are arranged parallel to each other; A wiring segment, wherein a first end of the wiring segment is connected to a second end of a contact segment; the second end of the wiring segment is provided with a bending structure, and the bending structure is provided with a piercing port; the wiring segments of each terminal pin along the first direction are arranged in a tentacle-like pattern; the wiring segments of each terminal pin along the second direction are arranged in an alternating pattern.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

The X direction shown in the diagram is the first direction, and the Y direction is the second direction.

[0026] like Figures 1 to 5 As shown, this embodiment provides a stamped terminal, including: a plurality of terminal pins 1000 integrally stamped, the plurality of terminal pins 1000 being arranged side by side along a first direction and connected by a strip 2000; the terminal pins 1000 include: a contact section 1100 and a wiring section 1200. The contact segment 1100 is a strip-shaped structure extending along a second direction, wherein the second direction is perpendicular to the first direction; the first end of the contact segment 1100 is connected to the material strip 2000; the contact segments 1100 of each terminal pin 1000 along the first direction are arranged parallel to each other; the first end of the wiring segment 1200 is connected to the second end of the contact segment 1100; the second end of the wiring segment 1200 is provided with a bending structure 1210, and the bending structure 1210 is provided with a piercing port 1220; the wiring segments 1200 of each terminal pin 1000 along the first direction are dispersed in an antenna-like shape; the wiring segments 1200 of each terminal pin 1000 along the second direction are staggered.

[0027] In this embodiment, the multiple terminal pins, integrally stamped, avoid the connection gaps and stress concentration problems caused by separate assembly, resulting in higher overall structural strength and significantly improved vibration and impact resistance. Furthermore, the integrally stamped terminal pins reduce contact resistance losses in traditional connection methods, making the current transmission path smoother and the conductivity higher. Simultaneously, the antenna-like, dispersed wiring segments increase the contact area with air, and the staggered arrangement forms an airflow channel, accelerating heat dissipation during terminal operation, preventing material performance degradation due to localized heat accumulation, and extending the terminal's service life.

[0028] In this embodiment, the bending structure of the wiring segment provides a suitable force angle for the setting of the piercing port. When the wire is engaged with the piercing port, the elastic deformation of the bending structure can generate a stable clamping force, ensuring that the piercing port can reliably penetrate the wire insulation layer and make close contact with the wire core, thereby reducing contact resistance fluctuations.

[0029] In this embodiment, the contact segments arranged parallel to the first direction can form a precise alignment with the sockets or pins of the mating connector, ensuring uniform force on the contact points of each terminal pin. This avoids insufficient or excessive local contact pressure caused by misalignment, improving contact stability and service life during insertion and removal. Furthermore, the parallel arrangement of the contact segments can reduce the length difference of the signal transmission path, thereby reducing signal delay and phase deviation.

[0030] In this embodiment, the wiring segments, dispersed in a tentacle-like pattern along the first direction and staggered along the second direction, maximize the use of three-dimensional space within a limited area. This satisfies the high-density integration requirements of multi-pin terminals while providing ample space for wire organization and fixation, reducing the risk of wire tangling. Simultaneously, the tentacle-like dispersion of the wiring segments along the first direction increases the contact area with air. Combined with the airflow channel formed by the staggered arrangement of the wiring segments along the second direction, this accelerates heat dissipation during terminal operation, preventing material performance degradation due to localized heat accumulation and extending the terminal's service life. It should also be noted that the tentacle-like dispersion of the wiring segments along the first direction avoids physical interference between adjacent wiring segments during wire insertion, while the staggered arrangement of the wiring segments along the second direction reduces the electromagnetic coupling area between the wiring segments through height differences.

[0031] In one embodiment, the antenna-shaped distributed wiring segments along the first direction can reduce signal crosstalk between adjacent terminal pins by increasing the spacing between adjacent wiring segments. Especially in high-speed signal transmission scenarios, it can effectively suppress electromagnetic interference and significantly improve the signal-to-noise ratio of signal transmission.

[0032] In one embodiment, the contact segment 1100 includes: a first transition segment 1110, an extension segment 1120, and a second transition segment 1130. The first transition segment 1110 has an arc-shaped structure; a first end of the first transition segment 1110 is connected to the material strip 2000; a first end of the extension segment 1120 is connected to a second end of the first transition segment 1110; the second transition segment 1130 has a Z-shaped structure; a first end of the second transition segment 1130 is connected to a second end of the extension segment 1120; and a second end of the second transition segment 1130 is connected to a first end of the wiring segment 1200.

[0033] In this embodiment, the first transition segment 1110 adopts a smooth arc-shaped slope structure, which forms a natural buffer at the connection between the contact segment 1100 and the material strip 2000, effectively dispersing local stress during material strip transmission, terminal separation and subsequent assembly processes, significantly improving the overall bending and fatigue resistance of the contact segment, and extending the service life of the terminals.

[0034] In this embodiment, the second transition segment 1130 adopts a Z-shaped structure to form a clear structural positioning reference. During assembly of the stamped terminal and the mating connector, it can precisely match the limiting structure inside the connector, restricting the offset of the contact segment and improving the structural stability after assembly. Furthermore, it increases the contact area between the contact segment and the insulating shell, further enhancing the fixing strength of the stamped terminal within the insulating shell and reducing the risk of loosening under vibration. It should be noted that the insulating shell serves as the load-bearing and protective structure for the stamped terminal. Generally, the insulating shell has multiple insertion interfaces, and the contact segments of each terminal pin are inserted one-to-one into the insertion interfaces, with the wiring segments of each terminal pin protruding from the insulating shell. The stamped terminal forms a precise electrical connection with the external connector through the insulating shell, mainly relying on the contact segment 1100 for stable mating. The mating end of the connector has pins or holes that correspond one-to-one with the terminal pins of the stamped terminal 1000, and their spacing and number perfectly match the lateral parallel arrangement of the terminal pins.

[0035] In one embodiment, the second end of the extension 1120 is provided with a wing 1121. The wing 1121 provided in this embodiment increases the structural strength of the connection between the extension 1120 and the wiring segment 1200, and avoids deformation of the extension 1120 due to bending stress of the wiring segment 1200.

[0036] In one embodiment, a pre-cracked notch 1111 is provided at the location where the contact section 1100 of the terminal pin 1000 connects to the strip 2000; alternatively, the pre-cracked notch 1111 is provided at the first end of the first transition segment 1110. In this embodiment, during the separation process of the stamped terminal and the strip, the fracture path can be guided to concentrate at the pre-cracked notch 1111, making the separation process more controllable, resulting in a smooth, burr-free fracture surface. This avoids structural damage such as deformation or cracking of the first transition segment 1110 or the extension segment 1120 due to forced separation, ensuring the original dimensional accuracy of the contact section 1100. The shape of the pre-cracked notch 1111 can be V-shaped or U-shaped; no specific limitation is made here.

[0037] It is also important to note that the multiple terminal pins 1000 are arranged side-by-side along the first direction and connected by a transverse spacer 3000. The transverse spacer 3000 connects the multiple terminal pins 1000 into a whole, forming a rigid frame structure. In processes such as stamping, strip conveying, electroplating, and inspection, it can effectively constrain the relative positions of each terminal pin 1000, preventing the terminal pins 1000 from shifting, tilting, or deforming due to external forces (such as conveying tension or stamping impact), and ensuring that the accuracy of key dimensions such as the spacing and parallelism between each terminal pin 1000 meets the design requirements.

[0038] A brief introduction to the separation of the strip and the shearing of the transverse spacer 3000 is provided. First, the terminal pins 1000, after being encapsulated by the injection mold, are placed in a dedicated tooling fixture. Next, a pre-cut notch 1111 is provided at the connection point between the contact section 1100 of the terminal pin 1000 and the strip 2000, causing the strip to break along a preset path, achieving initial separation of the strip from each terminal pin 1000. At this point, it is necessary to check whether the terminal pins 1000 and the transverse spacer 3000 have deformed due to force, ensuring the integrity of the encapsulated shell. Further, the stamped terminals, after strip separation, are transferred to a shearing fixture. After the fixture is positioned, the shearing blade is aligned with the transverse spacer 3000 connecting each terminal pin 1000 and a shearing force is applied transversely to the spacer, completely removing the transverse spacer 3000 between adjacent terminal pins 1000, forming independent terminal pins 1000.

[0039] In one embodiment, the puncture port 1220 includes a wire groove 1221 and a knife groove 1222; the wire groove 1221 is formed on the bending structure 1210; the knife groove 1222 is located at the end of the bending structure 1210 and is connected to the wire groove 1221.

[0040] Here's a brief overview of the process of piercing the wire using the piercing port 1220. First, the insulation layer of the wire does not need to be stripped beforehand; only oil or impurities on the wire surface need to be cleaned. Align the wire with the sharp contact point (i.e., the knife-edge groove 1222) of the piercing port 1220 to avoid misalignment and poor contact. Next, pressure is applied to the contact area between the wire and the piercing port. Under this pressure, the elastic deformation of the bending structure 1210 causes the sharp contact point (i.e., the knife-edge groove 1222) of the piercing port 1220 to gradually penetrate the wire insulation layer. The pressure is maintained for several seconds and then released. At this point, the contact point of the piercing port 1220 has formed a mechanical engagement and electrical connection with the wire core. The stability of the connection can be determined by observing whether the wire is firmly embedded in the groove 1221 of the piercing port 1220 (no loosening when gently pulled).

[0041] As an optional embodiment, the piercing port 1220 has a Y-shaped groove structure. In this embodiment, the blade groove 1222 has a V-shaped groove structure, and the wire groove 1221 has a linear groove structure, providing more ample space for the wire.

[0042] As an optional embodiment, the knife-edge groove 1222 has a V-shaped groove structure. This embodiment does not impose specific restrictions on the shape of the wire groove 1221, and it can be adjusted according to the actual working conditions.

[0043] In one embodiment, the bending angle of the bending structure 1210 is 90°. However, it should be noted that the bending angle of the wiring segment's bending structure should be set so that the piercing port 1220 forms a natural guide angle, allowing the wire to slide smoothly into the wire groove 1221 along the inclined surface of the knife-edge groove 1222 when inserted. The specific bending angle is not a limitation and can be adjusted according to actual working conditions.

[0044] In one embodiment, the bending angle of the bending structure can be adapted to conductors with different insulation thicknesses. When the insulation layer of the conductor is thicker, the bending angle of the bending structure can be increased to provide a stronger piercing force by utilizing greater bending elastic deformation. Conversely, when the insulation layer of the conductor is thinner, the bending angle of the bending structure can be reduced accordingly to narrow the range of elastic deformation. When pressure is applied, the sharp contact point at the piercing end can penetrate the thinner insulation layer more gently, avoiding insulation layer breakage or excessive compression and scratching of the wire core due to excessive piercing force.

[0045] In one embodiment, the number of terminal pins 1000 is five. This embodiment supports the simultaneous connection of five independent wires, perfectly adapting to scenarios requiring parallel transmission of multiple signals and power. The five terminal pins 1000 configured in this embodiment can achieve integrated connections of positive power, negative power, and three signals (or two signals and one ground) within a single insulating housing space, without requiring additional stamped terminals. This significantly improves the space utilization and integration of circuit connections, making it particularly suitable for the internal wiring of miniaturized electronic devices.
