PH2.54-01-20PZD 单排直插方针排针产品概述

一、产品核心定位与典型应用场景

PH2.54-01-20PZD是讯普(XUNPU)推出的通用型单排直插方针排针,针对20位信号/小功率电源传输场景设计,适配2.54mm国际标准间距。核心定位为“高可靠性、低成本、易集成”,广泛覆盖以下领域:

  • 工业控制:PLC模块、传感器接口、小型控制器电路板;
  • 消费电子:智能家电主板、手持扫码枪、音响系统内部连接;
  • 仪器仪表:万用表、示波器的信号输出接口;
  • 车载周边:车载充电器、行车记录仪的电路连接。

二、关键技术参数详细说明

该产品参数围绕“结构兼容性、电气稳定性、环境适应性”优化,核心参数如下:

参数类别 具体参数 关键说明 结构参数 1×20P(单排20位)、间距2.54mm、方针、直插 单排节省空间,方针接触更稳定 电气参数 额定电流3A、黄铜触头、镀金镀层 满足小功率电源+信号传输,接触电阻≤20mΩ 机械参数 配合针长6mm、塑高2.5mm、端接针长3mm 配合深度足够,塑壳紧凑,焊接适配性好 环境参数 工作温度-40℃~+105℃、黑色塑壳 宽温适应高低温场景,耐脏易识别

三、结构设计的实用优势

1. 方针设计提升接触可靠性

相比圆针,方针的平面接触面积更大(同直径下约为圆针的1.5倍),电流传输时发热更低;同时方针的“线性接触”特性,插入排母时不易偏移,减少针脚弯曲风险。

2. 紧凑塑高适配轻薄设备

2.5mm塑高(塑料基座高度)是行业紧凑设计,在保证针脚间距精度(±0.1mm)的前提下,可节省PCB垂直空间约30%,适合追求轻薄的消费电子或小型工业设备。

3. 直插端接适配标准PCB

端接针长3mm,刚好匹配标准PCB通孔(直径0.81.0mm、深度23mm),焊接时锡液可充分填充间隙,减少假焊、虚焊概率;配合针长6mm,插入排母时有效接触长度足够,插拔后不易松动。

四、材料与镀层的可靠性保障

1. 黄铜触头:导电与强度平衡

触头采用优质H65黄铜,导电率达1.07×10^7 S/m(接近纯铜),机械强度适中,可承受多次插拔不变形;黄铜耐腐蚀性能优于纯铜,避免长期使用中触头氧化。

2. 镀金镀层:防氧化+抗磨损

触头表面镀硬金(厚度≥0.5μm),金的化学稳定性极强,潮湿/高温环境下仍保持低接触电阻;硬金硬度(约120HV)高于纯金,减少插拔磨损,插拔寿命可达500次以上。

3. 黑色塑壳:耐高温+耐老化

塑壳采用PA66工程塑料,可承受波峰焊(240260℃)、回流焊(250270℃)高温,耐老化性能优异,长期使用不裂不变形;黑色外观耐脏,便于设备内部识别。

五、环境适应性与应用兼容性

1. 宽温范围覆盖多元场景

工作温度-40℃~+105℃,适配:

  • 低温场景:北方户外设备、冷库传感器连接;
  • 高温场景:车间控制柜(夏季内部60~70℃)、车载设备(暴晒后超80℃)。

2. 标准间距兼容主流配件

2.54mm是国际通用间距,与90%以上2.54mm排母、跳线帽兼容,无需定制配件,可直接集成到现有系统,降低设计/采购成本。

六、安装与维护注意事项

1. 焊接操作要点

  • 手工焊接:烙铁温度300~350℃,焊接时间≤3秒(避免塑壳变形);
  • 波峰焊:焊料温度240260℃,焊接时间35秒,冷却后再插拔。

2. 插拔与存储建议

  • 插拔需垂直施力,避免倾斜弯针;
  • 未使用产品存放在干燥(湿度40%60%)、通风(030℃)、无腐蚀气体环境,避免塑壳老化/触头氧化。

该产品由讯普按行业标准生产,质量稳定、性价比突出,是各类电子设备内部信号/小功率电源连接的理想选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
