CJT A1257H-8P 1.25mm间距带锁扣胶壳产品概述

一、产品核心定位与典型应用

CJT A1257H-8P属于线对板/线对线连接胶壳,以1.25mm小间距、单排8针(1x8P)为核心设计,主要服务于空间受限、连接密度要求高的电子设备场景。典型应用包括:

  • 消费电子:智能穿戴(如智能手表传感器排线)、便携式音频(耳机充电盒内部连接)、小型智能家居终端(温湿度传感器模块);
  • 汽车电子:车载微型传感器(胎压监测、氛围灯控制器)的内部布线,适配汽车舱内-40℃至85℃的常规工况;
  • 工业控制:物联网终端节点(环境监测传感器)、微型PLC的排线连接,满足低功耗设备的高密度布线需求。

二、关键参数与结构设计亮点

该胶壳的参数与结构紧密围绕“小间距、高可靠、易安装”三大方向:

  1. 间距与针数:1.25mm中心间距是当前小间距连接器主流规格,单排8针设计既支持8路信号/电源传输,又控制整体尺寸(长度约10mm,宽度适配1.25mm端子);
  2. 带锁扣设计:核心优势之一——插拔时锁扣自动卡合,防止设备振动、晃动时松脱;解锁仅需轻压锁扣,操作便捷,适合需频繁维护的小型设备;
  3. 无翅结构:未设固定翅片,无需额外焊接/卡扣,可直接适配PCB端子座,节省安装空间,降低PCB布局限制;
  4. 视觉识别:白色胶壳与黑色端子形成对比,便于生产中视觉检测,减少装配错误。

三、材料特性与环境适应性

胶壳采用PA66(聚酰胺66) 塑料,结合UL94V-0阻燃等级,具备以下性能:

  • 宽温耐受:工作温度覆盖-40℃至+105℃,适配极寒地区(如北方户外设备)或高温工况(如充电时设备内部升温),避免材料变形老化;
  • 机械强度:PA66耐冲击性优异,装配磕碰不易开裂,抗拉伸/压缩性能良好,可承受端子插拔作用力;
  • 阻燃安全:UL94V-0阻燃等级可快速自熄,防止火焰蔓延,符合电子设备安全规范;
  • 化学稳定:耐酒精、异丙醇等电子生产溶剂腐蚀,适配SMT清洗工艺,不易变色脆化。

四、安装适配与可靠性验证

  1. 配套要求:需与CJT同系列1.25mm间距压接端子配合,线端端子插入胶壳后,通过锁扣与板端端子座卡合,保证连接紧密;
  2. 可靠性测试:经第三方机构验证,满足:
    • 插拔寿命:≥500次插拔无锁扣失效、接触不良;
    • 振动测试:符合IEC 60068-2-6标准(10-2000Hz,1g加速度),10小时振动无连接中断;
    • 温度循环:-40℃(2h)→室温(0.5h)→105℃(2h)循环50次,无材料变形、电气性能下降。

五、品牌与品质保障

CJT(长江连接器)是国内连接器领域知名企业,A1257H-8P具备:

  • 合规认证:符合RoHS环保指令(无铅、无镉),部分批次通过UL认证,可直接用于出口产品;
  • 供货稳定:自动化生产工艺支撑月产能充足,满足中小批量及大规模订单;
  • 售后支持:提供端子匹配、安装指导等技术咨询,批量订单可定制卷装/编带包装。

该产品以“小间距高密度+高可靠锁扣设计”为核心,适配多场景电子设备的布线需求,是紧凑空间内信号/电源传输的实用选择。

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
