CJT A1257H-2P 1.25mm间距带锁扣胶壳产品概述

一、产品核心规格参数

CJT A1257H-2P为1.25mm间距的单排胶壳,核心参数清晰适配小型化连接需求:

  • 插孔结构:1×2P(单排2个插孔),满足基础2线信号/电源连接;
  • 间距规格:1.25mm中心距,属于高密度布线的主流小间距;
  • 外观特征:白色PA66外壳,集成带锁扣设计,无定位翅结构;
  • 材料认证:塑料材质为PA66(聚酰胺66),阻燃等级达UL94V-0;
  • 环境范围:工作温度-40℃~+105℃,覆盖工业级、消费电子多场景;
  • 应用类型:支持线对板(与板端针座匹配)、线对线(与对应线端胶壳匹配)双模式。

二、设计特点与核心优势

2.1 小间距高密度适配

1.25mm间距可有效压缩布线空间,适配智能穿戴、微型传感器等小型化设备的紧凑布局,满足产品轻量化、微型化趋势。

2.2 带锁扣防松脱设计

胶壳集成专用锁扣,插合时与端子/板端连接器形成可靠卡合,插合到位有明确“咔哒”声提示;可抵抗振动、冲击(如车载、工业设备环境),避免连接松脱导致信号中断。

2.3 无翅简化安装

无定位翅设计减少安装空间占用,适配小型家电内部狭小区域;同时简化装配流程,降低人工操作难度与误差。

2.4 通用型连接兼容性

支持线对板、线对线双模式,可与CJT A1257系列端子、对应1.25mm针座/线端胶壳完美匹配,无需额外更换组件,提升组合灵活性。

三、材料与可靠性验证

3.1 PA66材质的性能优势

采用PA66(聚酰胺66)外壳,具备:

  • 机械强度:抗冲击、耐磨损,长期插拔不易开裂变形;
  • 耐化学性:抵抗酒精、弱酸碱等常见溶剂腐蚀,适配设备清洁场景;
  • 电气绝缘性:高绝缘电阻,避免短路风险;
  • 耐湿性:低吸水性,潮湿环境下性能稳定。

3.2 严苛环境可靠性

  • 宽温测试:经-40℃低温存储、+105℃高温老化,性能无衰减;
  • 阻燃安全:UL94V-0等级,离火30秒内自熄,符合防火要求;
  • 插拔寿命:常规插拔1000次以上,满足长期使用需求。

四、典型应用场景

CJT A1257H-2P因小间距、高可靠性,广泛应用于:

  1. 智能穿戴:智能手环、蓝牙耳机充电仓的电池与主板连接、心率传感器信号传输;
  2. 小型家电:便携式加湿器、电动牙刷的电源连接、控制模块布线;
  3. 车载电子:胎压监测接收器、氛围灯控制器的内部信号/电源连接;
  4. 工业控制:小型PLC模块、温度传感器节点的低功率连接;
  5. 医疗电子:血糖监测仪、便携式血氧仪的内部组件连接。

五、安装与维护注意事项

  1. 端子匹配:需搭配CJT A1257系列专用端子,确保接触精度;
  2. 插合操作:对准锁扣与插孔,避免强行插拔导致锁扣断裂;
  3. 安装确认:插合后检查锁扣是否完全卡合(无松动);
  4. 环境防护:避免长期暴露于强腐蚀气体,必要时做简单密封。

总结

CJT A1257H-2P胶壳凭借1.25mm小间距、带锁扣防松脱、宽温适配等优势,成为小型化电子设备内部连接的高性价比选择;PA66材质与UL94V-0阻燃等级,兼顾可靠性与安全,广泛适用于消费电子、车载、工业等多领域。

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
