CJT A1257H-4P 1.25mm间距带锁扣连接器产品概述
一、产品基本参数与结构特征
CJT A1257H-4P是一款1.25mm间距单排4PIN带锁扣胶壳，属于线对板/线对线连接系列，核心参数及结构清晰：
- 电气/机械基础：1排4芯设计，引脚间距1.25mm（比常规2.0mm间距缩小37.5%），适配高密度集成场景；
- 结构细节：自带锁扣结构（无翅设计），锁扣可与对应端子/胶壳精准卡合，防止振动下松脱；
- 材料与安全：塑料主体采用PA66（聚酰胺66），具备优异耐温性、机械强度及耐化学性，阻燃等级达UL94V-0（垂直燃烧无滴落）；
- 环境范围：工作温度覆盖-40℃~+105℃，可应对低温户外、高温车载等极端场景。
二、核心性能优势
高密集成适配小空间
1.25mm窄间距是同类常规间距的62.5%，能大幅压缩连接模块体积，尤其适合智能穿戴、小型车载传感器等对空间敏感的设备。可靠连接抗振动冲击
自带锁扣结构为核心优势——装配扣合后可承受5~10G振动（符合部分车规级要求），避免移动场景下的接触不良，提升系统稳定性。宽温阻燃保障安全
PA66材料+UL94V-0阻燃等级，既应对极端温度变化（如北方冬季户外、车载高温环境），又能在意外短路时抑制火焰蔓延，降低设备风险。装配便捷性
白色胶壳便于生产线上引脚识别与装配检查，无翅设计简化线端加工流程（无需处理翅片），降低组装工时与出错率。
三、典型应用场景
A1257H-4P因小体积、高可靠、宽温适配的特点，广泛覆盖以下领域：
- 消费电子：智能手表、TWS蓝牙耳机、便携式充电宝的内部连接（主板与电池、传感器模块）；
- 汽车电子：车载小功率传感器（胎压监测、温湿度传感器）、中控面板小按键的线对板连接；
- 工业控制：小型PLC I/O接口、工业传感器节点（温度/压力传感器）的信号传输；
- 医疗设备：便携式血糖仪、血压计的内部电路连接（需阻燃安全+体积紧凑）。
四、选型与适配注意事项
- 端子适配：需搭配CJT同系列1.25mm端子（如A1257系列端子），确保端子与胶壳锁扣卡合紧密；
- 连接匹配：线对线连接时，选用同系列线端胶壳（1x4P），避免两端锁扣错位；
- 装配规范：确认锁扣完全扣合（可通过轻微拉力测试验证），禁止超温（-40℃~+105℃）使用。
五、总结
CJT A1257H-4P以小体积、高可靠、宽温阻燃为核心亮点，精准匹配消费电子、汽车电子、工业控制等领域的小型化、高稳定连接需求，是替代常规宽间距连接器的高性价比方案。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
