CJT A3961WV-2P线对板针座产品概述

CJT(长江连接器)A3961WV-2P是一款单排2Pin线对板直插针座,属于CH系列标准化连接器产品,专为低压电气设备的导线与PCB板可靠连接设计,核心参数适配中等功率、宽温环境的应用需求,是工业控制、家电、仪器仪表等领域的基础连接组件。

一、产品核心定位与基本参数

该针座为1x2P(单排2针) 结构,引脚间距(Pitch)为3.96mm,采用插件式(DIP) 安装方式,总PIN数2P,是线对板连接的标准化基础组件。其核心参数明确了基础适配范围:

  • 引脚排列:单排2针,结构紧凑,占用PCB板空间小;
  • 安装方式:直插焊接,适配1.6mm标准PCB板焊盘设计,支持波峰焊、手工焊等常规装配工艺;
  • 系列归属:CH系列,与同系列端子、胶壳可配套使用,实现完整的线对板连接系统。

二、关键性能指标解析

A3961WV-2P的性能参数针对实际应用场景做了优化,关键指标的实际意义如下:

  1. 额定电流7A:相比2.54mm间距针座(常见3A~5A),电流承载能力更高,可满足小型电机、加热元件、中等功率传感器等设备的电流传输需求,避免过流发热风险;
  2. 额定电压250V:符合GB/T 16935.1低压电气设备安全电压要求,覆盖大多数民用(如家电)、工业低压(如PLC辅助电路)应用场景;
  3. 工作温度-40℃~+105℃:适配宽温环境,可用于户外设备(如太阳能控制器)、工业现场(如低温车间)等高低温变化场景,PA66塑料主体的耐温性支撑了这一宽温范围;
  4. 阻燃等级UL94V-2:通过UL阻燃测试,燃烧时自熄(无持续燃烧),可降低设备起火风险,满足家电、工业设备的安全规范要求。

三、材料与工艺特性

产品的可靠性依赖于材料选型与工艺设计,A3961WV-2P的核心材料特性如下:

  • 触头部分:采用黄铜基材+锡镀层。黄铜导电率高(约25%IACS),接触电阻低;锡镀层抗氧化、易焊接,焊接时可形成牢固的锡铅/无铅焊点,同时提高触头的插拔寿命;
  • 塑料主体:选用PA66(聚酰胺66) 。PA66机械强度高(抗拉强度约80MPa)、耐冲击,能承受装配时的插拔力;耐化学腐蚀(如弱酸、弱碱),适配工业环境;耐温性与产品工作温度范围匹配;
  • 结构设计:插针长度适配标准PCB板厚度,插拔力控制在10N~20N之间,既保证连接牢固不松脱,又便于手工或自动化装配。

四、安装与典型应用场景

4.1 安装方式

该针座为插件式安装,需配合PCB板的3.96mm间距焊盘设计:

  1. 将针座插针插入PCB板对应焊盘;
  2. 通过波峰焊(批量生产)或手工焊(小批量/维修)完成焊接固定;
  3. 焊接后可配合同系列CH端子、胶壳实现导线与针座的连接。

4.2 典型应用场景

A3961WV-2P的参数适配多个领域的线对板连接需求:

  • 家电领域:洗衣机水位传感器与控制板的连接、冰箱温度传感器的布线、小型空调的风机控制电路;
  • 工业控制:PLC(可编程逻辑控制器)的辅助信号输入、小型变频器的状态反馈连接、工业接近开关的布线;
  • 仪器仪表:数字万用表的内部电源连接、温度巡检仪的传感器接口、小型测试设备的信号输出;
  • 户外设备:太阳能路灯控制器的电池连接、户外监控设备的电源布线(适配-40℃低温环境)。

五、选型与使用注意事项

  1. 选型匹配:需确认PCB板焊盘间距为3.96mm、PIN数为2P,若需多针连接可选择同系列A3961WV-4P/6P等型号;若需带锁扣防松脱,需参考同系列带锁结构型号;
  2. 电流/电压限制:避免在超过7A额定电流、250V额定电压的场景使用,防止触头过热或绝缘失效;
  3. 环保要求:产品符合RoHS 2.0(无铅、无镉等有害物质)标准,适配出口或环保要求严格的设备;
  4. 品牌品质:CJT长江连接器是国内连接器行业主流厂商,产品通过ISO 9001质量管理体系认证,可靠性符合行业标准。

这款针座以高性价比、可靠性能,成为中等功率低压设备线对板连接的常用选择,可满足大多数民用与工业领域的基础连接需求。

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.

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
