接線端子內(nèi)部的金屬導(dǎo)體是端子的核心零件,它將來(lái)自外部電線或電纜的電壓,電流或信號(hào)傳遞到與其相配的連接器對(duì)應(yīng)的接觸件上。故接觸件必須具備優(yōu)良的結(jié)構(gòu),穩(wěn)定可靠的接觸保持力和良好的導(dǎo)電性能。由于接觸件結(jié)構(gòu)設(shè)計(jì)不合理,材料選用錯(cuò)誤,模具不穩(wěn)定,加工尺寸超差,表面粗糙,熱處理電鍍等表面處理工藝不合理,組裝不當(dāng),貯存使用環(huán)境惡劣和操作使用不當(dāng),都會(huì)在接觸件的接觸部位和配合部位造成接觸不良。
poor contact
The metal conductor in the terminal is the core part of the terminal, which transfers the voltage, current or signal from an external wire or cable to the contact corresponding to the connector to which it is matched. Therefore, the contact parts must have excellent structure, stable and reliable contact force and good electrical conductivity. Because the contact structure is not reasonable, the mold material selection errors, unstable machining dimension tolerance, surface roughness, heat treatment, electroplating and other surface treatment process is not reasonable, improper assembly, storage and operation environment of improper use will be in the contact portions of the contacts and the matched parts caused by poor contact.
2. 絕緣不良
絕緣體的作用是使接觸件保持正確的位置排列,并使接觸件與接觸件之間,接觸件與殼體之間相互絕緣。故絕緣件必須具備優(yōu)良的電氣性能,機(jī)械性能和工藝成型性能。特別是隨著高密度,小型化接線端子的廣泛使用,絕緣體的有效壁厚越來(lái)越薄。這對(duì)絕緣材料,注塑模具精度和成型工藝等提出了更苛嚴(yán)的要求。由于絕緣體表面或內(nèi)部存在金屬多余物,表面塵埃,焊劑等污染受潮,有機(jī)材料析出物及有害氣體吸附膜與表面水膜融合形成離子性導(dǎo)電通道,吸潮,長(zhǎng)霉,絕緣材料老化等原因,都會(huì)造成短路,漏電,擊穿,絕緣電阻低等絕緣不良現(xiàn)象。
bad insulation
The function of an insulator is to keep the contacts in the correct position and to keep the contact between the contact and the contact between the contact and the shell. Therefore, insulation must have excellent electrical performance, mechanical properties and process forming performance. Especially with the widespread use of high-density and miniaturized wiring terminals, the effective wall thickness of insulators becomes thinner and thinner. This is more stringent requirements for insulation materials, injection molding precision and molding process. Due to the presence of metal particles, the insulator surface or inner surface of the dust pollution, flux moisture, organic material precipitates and harmful gas adsorption and membrane fusion to form water film on the surface of ion conductive channel, absorption of moisture, mildew, material aging insulation, can cause leakage, short circuit, low breakdown, poor insulation insulation resistance the phenomenon of.
絕緣體不僅起絕緣作用,通常也為伸出的接觸件提供精確的對(duì)中和保護(hù),同時(shí)還具有安裝定位,鎖緊固定在設(shè)備上的功能。固定不良,輕者影響接觸可靠造成瞬間斷電,嚴(yán)重的就是產(chǎn)品解體。解體是指接線端子在插合狀態(tài)下,由于材料,設(shè)計(jì),工藝等原因?qū)е陆Y(jié)構(gòu)不可靠造成的插頭與插座之間,插針與插孔之間的不正常分離,將造成控制系統(tǒng)電能傳輸和信號(hào)控制中斷的嚴(yán)重后果。由于設(shè)計(jì)不可靠,選材錯(cuò)誤,成型工藝選擇不當(dāng),熱處理,模具,裝配,熔接等工藝質(zhì)量差,裝配不到位等都會(huì)造成固定不良。
fixed bad
Insulators not only provide insulation, but also provide accurate protection for the extended contacts, as well as the function of installation, positioning and locking on the equipment. Fixed bad, light influence contact reliable, cause instant power failure, serious is product disintegration. Refers to the disintegration of terminals inserted in the state, because of the material, design, technology and other causes between the plug and the socket structure caused by unreliable, between pin and Jack is not normal separation, will cause serious consequences of power transmission and signal control interrupt control system. Because of the unreliable design, the wrong material selection, the improper selection of the forming process, the poor quality of the heat treatment, the mold, the assembly, the welding, the assembly is not in place and so on, it will cause the fixed bad.
此外,由于鍍層起皮,腐蝕,碰傷,塑殼飛邊,破裂,接觸件加工粗糙,變形等原因造成的外觀不良,由于定位鎖緊配合尺寸超差,加工質(zhì)量一致性差,總分離力過(guò)大等原因造成的互換不良,也是常見(jiàn)病,多發(fā)病。接線端子的這幾種故障一般都能在檢驗(yàn)及使用過(guò)程中及時(shí)發(fā)現(xiàn)剔除。
In addition, because the coating peeling, corrosion, scratches, plastic flash, rupture, contact roughness, deformation and other reasons caused by poor appearance, due to positioning and locking with oversize, machining quality consistency is poor, poor exchange total separation excessive force causes, also is a common disease, frequently occurring disease. These faults can be found and eliminated in the process of inspection and use.
