TL;DR — Ibintu by'ingenzi byafashwe

Ibikoresho byo mu kirere bidafite screw bishobora kugabanya igihe cyo guteranya amatara ku kigero cya 35-50% ugereranije n'udukingirizo gakondo tw'imigozi, hashingiwe ku bipimo by'igihe cyo kwiga bivuye ku mirongo y'umusaruro w'ibikoresho by'amashanyarazi. Ku kigo gishinzwe amatara gitanga ibikoresho 50.000 buri mwaka, ibi bingana na $8.750-12.250 mu mafaranga azigamwa ku bakozi ku mwaka — mbere yo gutekereza ku nyungu z'inyongera zo kugabanya imirimo yo kuvugurura, gutanga garanti nke, no kunoza umusaruro.

Kubera ko buri connection ya screw terminal isaba umukozi Gufata screwdriver, guhuza bit y'umushoferi, gushyiramo umuvuduko wo hasi, kuzunguruka inshuro 2-4 zose (ubusanzwe bisaba amasegonda 3-5), no kugenzura torque haba ukoresheje ibyiyumvo cyangwa screwdriver ya torque - mu gihe terminal ya screw-in idafite screw isaba gusa gusunika insinga yakuwemo mu gice cy'umugozi kugeza igihe ikandagiye (amasegonda 1.5-2). Iryo tandukaniro ry'amasegonda 2-3 kuri buri guhuza rirushaho kwiyongera mu buryo butangaje mu mikorere myinshi.

Igiciro cya screw terminals: Isesengura ryimbitse

Ibikoresho gakondo byo kugabanya ibyuma byakoreshejwe mu nganda byamaze imyaka ibarirwa muri za mirongo ari byo bisanzwe, ariko ibiciro byabyo byihishe biragaragara iyo bipimwe ku gipimo cy'umusaruro. Uburyo bwo guteranya ibyuma bifunga imigozi bukubiyemo intambwe nyinshi zongerera igihe, zigashyiramo impinduka, kandi zigateza ingaruka ku bwiza.

Ku kigo gishinzwe amatara gitanga ibikoresho 50.000 ku mwaka gifite impuzandengo y'insinga 6 kuri buri gikoresho, igihe cyose cyo guteranya kizigamwa no guhindura ibyuma bitagira screw ni amasaha 750 ku mwaka. Ku gipimo cy’abakozi bavanze (harimo inyungu n’inyungu) cya $15-18 ku isaha mu turere nka Megizike, Uburayi bw’Iburasirazuba, cyangwa Aziya y’Amajyepfo y’Uburasirazuba, ibyo bingana n’amadolari 11,250-13,500 mu bwizigame bwa buri mwaka. Mu turere duhembwa imishahara myinshi (Amerika cyangwa Uburayi bw’Iburengerazuba ku madolari 25-35 ku isaha), ubwizigame bugera ku madolari 18,750-26,250 ku mwaka ku musaruro umwe.

Uretse umurimo: Gusubiramo imirimo no kuzigama amafaranga yo kuyikoresha muri garanti

Kugabanuka kwa 40% by'igihe cyo guteranya ni cyo gipimo cy'ingenzi, ariko sosiyete zikora akazi ko guteranya ibikoresho (OEM) zimaze guhindura ibyuma bitagira imigozi zitangaza ko zagabanyije cyane ibikorwa byo kongera gukora no gutanga garanti.

Kubera ko imiyoboro y'ibyuma ishobora kwangirika mu buryo butatu, ibyo imiyoboro y'amashanyarazi idakoresha screw ikuraho burundu: gufunga bidahagije (umukoresha arahagarara mbere yo kugera ku muvuduko wuzuye), gufunga cyane (gukuraho imigozi cyangwa kumena umutwe w'ibyuma), no kurekura bitewe no guhindagura mu gihe cyo kohereza cyangwa mu gihe cyo gukoresha.

Itandukaniro ry’igipimo cyo kuvugurura imikorere ryonyine ritanga kuzigama amafaranga menshi: ku giciro cyo kuvugurura imikorere kiri hagati ya $2.00-3.50 kuri buri gice (umurimo + ibikoresho bisimbura + ibizamini), kugabanya 2% by’ivugurura imikorere ku bice 50.000 bizigama $2.000-3.500 buri mwaka. Icy'ingenzi kurushaho, igipimo cyo hasi cyo gutsindwa kw'ibikoresho (0.05-0.15% ugereranije na 0.5-1.5%) bigabanya mu buryo butaziguye ikiguzi cyo gusaba garanti, akenshi kigera kuri $15-35 kuri buri kirego harimo ibijyanye n'ibikoresho, igice cyo gusimbuza, n'amafaranga asabwa ku bakiriya.

Igiciro cyose cy'umutungo: Isesengura ry'imyaka 5

Mu gusuzuma ibyuma bitagira screw ugereranije na screw terminal blocks ku isosiyete ikora amatara, icyemezo kigomba gushingira ku giciro cy’umutungo (TCO) mu gihe cy’ubuzima bw’ibicuruzwa, ntabwo ari itandukaniro ry’igiciro cya buri gice. Ibikoresho bya terminal bitagira screws akenshi bihenda 10-25% kuri buri gice kurusha screws zingana na byo, ariko amafaranga azigama mu mikorere aruta cyane ayo mafaranga y’inyongera.
