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:
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:
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。
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。
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。
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:
PA66(聚酰胺66)是工程塑料中的常用材料,具备以下特性:
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。
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。
基于上述性能特点,A3963H-3P可广泛应用于以下领域:
为确保A3963H-3P的稳定使用,需注意以下要点:
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
