CJT A3963H-3P线对板/线对线胶壳产品概述

一、产品定位与核心规格

CJT(长江连接器)A3963H-3P是一款专为线对板、线对线连接设计的紧凑型胶壳,核心针对小空间、高可靠性的电气连接需求。其核心规格清晰明确:

  • 连接结构:1排3PIN(1×3P)插孔布局,单排设计紧凑;
  • 间距参数:3.96mm(P=3.96mm),适配同间距端子与对插胶壳;
  • 外观与结构:白色外观,带锁扣设计(提升连接可靠性),不带翅片(简化安装、节省空间);
  • 材料与性能:塑料材质为PA66(聚酰胺66),阻燃等级达UL94V-0,工作温度范围覆盖-40℃至+105℃。

二、结构设计与性能特点

A3963H-3P的结构设计围绕「可靠连接+紧凑适配」展开,核心特点如下:

1. 带锁扣设计提升抗振可靠性

锁扣是该胶壳的核心设计亮点:对插时锁扣可与配合端(端子或对插胶壳)精准卡合,形成机械锁定,能有效抵抗运输振动、工业现场冲击(如机床、电机振动),避免连接松脱导致的信号中断或电源故障,尤其适合对可靠性要求较高的场景。

2. 1×3P紧凑布局适配小空间

单排3PIN的布局尺寸小巧,可在设备内部紧凑空间(如小型PLC、家电控制板)中灵活安装,无需额外预留过大空间;同时,不带翅片的设计进一步减少了安装干涉,简化了装配流程,降低了生产工时。

3. 电气与机械配合精度

该胶壳与CJT同系列3.96mm间距端子(如A3963系列端子)采用精准配合设计,确保端子插入后接触稳定,接触电阻低,信号传输损耗小;胶壳插孔的定位精度高,可避免端子错位导致的接触不良。

三、材料与环境适应性

A3963H-3P选用的PA66塑料及性能参数,使其具备广泛的环境适应性:

1. PA66塑料的综合优势

PA66(聚酰胺66)是工程塑料中的常用材料,具备以下特性:

  • 机械强度高:可承受多次插拔而不变形,插拔寿命长;
  • 耐冲击性好:能抵抗轻微碰撞,降低运输或使用中的损坏风险;
  • 耐化学性:对工业常见的油、弱酸、弱碱有一定耐受性,适应复杂工况。

2. UL94V-0阻燃等级

该胶壳通过UL94V-0阻燃认证,属于垂直燃烧测试的最高等级之一:离开火源后火焰在10秒内熄灭,且不会产生滴落物引燃下方材料,满足电子设备的安全阻燃要求,尤其适合医疗、工业控制等对防火有严格规范的领域。

3. 宽温工作范围

工作温度覆盖-40℃至+105℃,可适应不同地区的极端环境:低温下(如北方冬季户外设备)塑料不会脆化开裂,高温下(如南方夏季车间)不会软化变形,确保全年稳定运行。

四、典型应用场景

基于上述性能特点,A3963H-3P可广泛应用于以下领域:

1. 工业控制领域

  • PLC(可编程逻辑控制器)的I/O模块与传感器、执行器的连接;
  • 变频器、伺服驱动器的控制信号接口;
  • 工业机器人的末端执行器信号传输。

2. 家电与消费电子

  • 小型洗衣机、空调的内部 wiring 连接(如控制面板与电机的控制线路);
  • 智能家居设备(如智能门锁、温湿度传感器)的内部模块连接。

3. 通信与汽车电子

  • 小型通信终端(如路由器、交换机)的内部模块连接;
  • 汽车低功耗模块(如车载摄像头、传感器)的辅助连接(需符合汽车级要求的场景需提前确认)。

五、选型与使用注意事项

为确保A3963H-3P的稳定使用,需注意以下要点:

1. 配件匹配要求

必须使用CJT同系列3.96mm间距的端子(如A3963系列端子)及对插胶壳,避免使用非匹配配件导致接触不良、机械干涉或损坏。

2. 锁扣安装确认

对插时需听到锁扣「咔嗒」的锁定声,确认完全卡合;若未卡合,需重新插拔,否则振动环境下易松脱。

3. 环境与存储要求

  • 避免长期暴露在阳光直射(可能加速塑料老化)、强酸碱环境(如浓盐酸、浓硫酸);
  • 存储时建议放置在温度040℃、湿度40%60%的干燥环境中,远离热源与潮湿。

4. 插拔规范

插拔时需垂直于胶壳方向施力,避免倾斜导致端子或胶壳变形;禁止强行插拔,以免损坏内部结构。

综上,CJT A3963H-3P凭借紧凑设计、可靠锁扣、宽温阻燃等特性,成为小空间电气连接场景的高性价比选择,可满足工业、家电、通信等多领域的稳定连接需求。

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.
