CJT长江连接器A3961H-3P产品概述

一、产品核心参数与基础定位

A3961H-3P属于长江连接器(CJT)3.96mm间距系列,主打紧凑空间下的小功率信号/电源连接,适配多种常规电子设备的内部接口需求。核心参数如下:

  • 机械结构:单排(1排)3PIN(1x3P),插孔间距3.96mm,无锁扣、无带翅设计;
  • 外观与材料:透明色外壳,塑料材质为PA66(尼龙66),具备UL94V-0阻燃等级;
  • 环境适应性:工作温度范围-40℃至+105℃,覆盖多数常规电子设备使用场景;
  • 品牌背书:CJT为国内连接器行业知名品牌,产品质量稳定、供应周期可控。

二、设计特点与性能优势

1. 紧凑适配的结构设计

3.96mm是行业应用广泛的连接器间距,兼顾连接可靠性与空间利用率;1x3P的PIN数设计,可满足单路低功率电源(如5V/12V) 或多路信号(如3路模拟/数字信号) 的连接需求,尤其适合小型化设备(如智能音箱、小型PLC)的内部布局。

无锁扣、无带翅的简化结构,降低了装配难度,同时避免了额外机械干涉,适配更多灵活场景(如狭小空间内的板对板、线对板连接)。

2. 可靠的材料与阻燃性能

外壳采用PA66材质,具备三大优势:

  • 机械强度高:抗冲击、耐磨损,长期使用不易因振动导致外壳开裂;
  • 耐化学性好:可抵抗弱酸碱腐蚀,适配部分工业场景的环境要求;
  • 阻燃安全:UL94V-0等级意味着离开火源后10秒内自熄,有效降低设备起火风险,符合电子设备安规标准。

3. 宽温环境适应性

工作温度覆盖-40℃至+105℃,可适应:

  • 寒冷地区(如北方户外设备辅助模块);
  • 高温环境(如家电内部发热区域、车载小电器);
    无需额外添加温控组件,提升了产品的环境兼容性。

4. 透明外壳的可视化优势

透明色外壳可直接目视检查PIN脚压接状态、端子插入深度,便于:

  • 生产线上快速质量管控(避免虚接、漏接);
  • 售后维修时故障排查(快速判断是否存在PIN脚松动、脱落);
    减少维护时间与成本,提升设备运行稳定性。

三、典型应用场景

A3961H-3P凭借紧凑结构与可靠性能,广泛应用于以下领域:

  • 消费电子:小型家电(加湿器、智能台灯、空气净化器)的传感器模块与主控板连接、低功率电源接口;
  • 工业控制:小型PLC辅助接口、温度/湿度传感器节点的信号输出;
  • 通信设备:小型路由器、交换机的电源板与主板连接;
  • 汽车电子(非核心):车载小电器(点烟器扩展器、车载香薰机)的内部控制连接。

四、安装与使用注意事项

为确保性能与寿命,建议遵循以下规范:

  1. 端子适配:必须搭配CJT同系列3.96mm间距端子(如压线端子),避免非匹配端子导致虚接、短路;
  2. 压接操作:使用对应间距的压线工具,压接压力需符合工具要求(避免过度压接损坏外壳,或压力不足导致接触不良);
  3. 环境限制:禁止在超过-40℃~+105℃、强酸碱腐蚀、持续浸泡的环境中使用;
  4. 定期检查:每6个月通过透明外壳目视检查PIN脚连接状态,松动则重新压接,避免接触电阻过大发热。

五、总结

A3961H-3P是一款针对小功率连接需求设计的高性价比连接器,以3.96mm间距、1x3P结构为核心,结合PA66阻燃材料、宽温适应性与透明可视化设计,具备结构灵活、安全可靠、维护便捷等优势,可广泛适配消费电子、工业控制、通信等领域的常规设备内部连接,是小型化电子设备的理想选择。

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
