TE Connectivity(泰科)的172157-1是一款专为小型化电子设备设计的2PIN紧凑型连接器,凭借紧凑结构、可靠锁扣与固定设计,在消费电子、工业控制等领域广泛应用。以下从核心规格、结构特点、性能参数等维度详细介绍。
172157-1属于TE旗下MINI系列连接器,主打小体积高集成的连接需求,核心基本规格明确:
该型号主要作为板端连接器(带翅适配PCB焊接),匹配对应线端连接器实现电路连接,是小型设备内部信号/低功率电流传输的理想选择。
172157-1的结构设计围绕“紧凑性+可靠性”两大核心:
锁扣采用弹性塑料卡扣结构,插拔到位后自动卡合,需手动按压解锁;可有效避免设备运输振动、现场碰撞导致的连接器松脱,尤其适合对连接稳定性要求高的工业场景(如PLC小模块)。
外壳两侧带金属固定翅(用户明确“带翅”),焊接时翅片与PCB贴合,增加连接器与PCB的机械连接面积,防止因导线拉扯、外力撞击导致连接器脱离PCB,提升长期可靠性。
单排2PIN设计(针距符合TE常规小型连接器标准,如2.54mm),占用PCB面积仅约常规连接器的1/3,适配小型化模块(如传感器节点、微型控制器)的空间限制。
PA66具有优异的机械强度(抗冲击、耐磨损)、耐化学性(抗酒精、丙酮等常见溶剂腐蚀),且加工性能好,适合连接器外壳的复杂结构成型;配合UL94V-0阻燃等级,离火后10秒内熄灭且无滴落物,满足电子设备的消防安全要求。
作为小型2PIN连接器,172157-1额定电流约13A(取决于接触件表面处理),额定电压≤50VAC/DC;接触件采用磷铜合金(高导电性),表面可选镀金(0.51μin)或镀锡(提升耐腐蚀性),连接电阻稳定(通常≤20mΩ),满足信号传输与低功率电流需求。
工作温度-20℃~+105℃覆盖大部分室内环境(如智能家居、办公设备)及一般工业场景(如小型PLC模块);同时具备耐盐雾性能(符合IEC 60068-2-11标准),可应对轻度潮湿环境。
172157-1因紧凑结构与可靠设计,广泛应用于以下场景:
带翅设计适配通孔焊接工艺,翅片可辅助定位,焊接效率高;锁扣插拔无需额外工具,单手即可完成锁定/解锁,现场维护方便。
TE连接器通常经过严格测试:振动测试(符合MIL-STD-202 Method 213)中连接电阻变化≤5%;冲击测试(Method 211)无松脱或接触不良;插拔寿命≥500次,满足设备长期使用需求。
符合UL、CSA等国际安全认证,外壳UL94V-0阻燃等级满足北美、欧洲等地区的电子设备安全标准,可直接用于出口产品。
总结:TE 172157-1以紧凑体积、可靠锁扣与固定设计,成为小型化电子设备内部连接的高性价比选择,适配多场景的信号与低功率电流传输需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
