A1257H-12P 产品概述

一、产品概述

A1257H-12P 是长江连接器(CJT)推出的一款 1x12P 胶壳,适用于线对板与线对线连接场合。该产品间距 1.25mm、单排 12 针,外观为白色,带锁扣设计,便于可靠插拔与防脱落,常用于细间距信号线束与小型电子设备的连接。

二、主要参数

  • 插孔结构:1x12P(单排12针)
  • 间距(Pitch):1.25mm(P=1.25mm)
  • 颜色:白色
  • 是否带锁扣:带锁扣(确保连接稳定)
  • 是否带翅:不带翅
  • 塑料材质:PA66
  • 阻燃等级:UL94V-0
  • 工作温度:-40℃ ~ +105℃
  • 品牌:CJT(长江连接器)

三、结构与材质特点

外壳采用工程塑料 PA66 注塑成型,材料通过 UL94V-0 阻燃等级认证,耐温、耐老化性能良好。锁扣结构为一体式设计,插入时卡位可靠,拔出时可通过按压释放,便于装配与维护。无侧翅设计适合空间受限的工况,节省 PCB 或线槽空间。

四、功能与优势

  • 细间距 1.25mm 适配高密度布线要求,节省空间;
  • 带锁扣大幅提升连接可靠性,防止振动或拉扯导致松脱;
  • PA66 与 UL94V-0 提供良好阻燃与耐温特性,适合多种环境;
  • 单排 12P 规格通用性高,易于与标准 1.25mm 系列公头/母头配合使用。

五、典型应用场景

  • 消费类电子产品:如便携式设备、充电仓、显示模组等;
  • 工业控制与通信设备:信号线连接、模块间互联;
  • 小型家电与智能硬件:传感器线束、控制板接口;
  • 其他细间距线束与端接需求场合。

六、选购与安装建议

  • 确认配套端子与压线工具匹配,推荐使用与 CJT 指定型号兼容的压接端子;
  • 检查所用公/母头间距为 1.25mm,避免误配;
  • 插拔时以直线方向进行,按压锁扣后拔出以保护锁扣结构;
  • 如在高温或特殊化学环境使用,请与供应商确认材料兼容性。

七、兼容性与检验

A1257H-12P 可与市场上通用的 1.25mm 间距连接器系列匹配,但为保证最佳可靠性建议配套 CJT 系列公头或经认证的等效件。出货前应进行外观、卡合、针位与绝缘测试,必要时做循环插拔寿命验证。

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
