Ceangail Cábla

Is cineál ceanglóir é carbhat cábla (ar a dtugtar comhionannas vótaí píobáin freisin), chun míreanna a choinneáil le chéile, go príomha cáblaí leictreacha, agus sreanga. Mar gheall ar a gcostas íseal, éasca le húsáid, agus neart ceangailteach, tá naisc cábla uileláithreach, ag baint úsáide as raon leathan d'iarratais eile.

The common cable tie, normally made of nylon, has a flexible tape section with teeth that engage with a pawl in the head to form a ratchet so that as the free end of the tape section is pulled the cable tie tightens and does not come undone . I measc roinnt ceangail tá cluaisín ar féidir a bheith depressed chun an ratchet a scaoileadh ionas gur féidir an carbhat a scaoileadh nó a bhaint, agus b'fhéidir é a athúsáid. Déanann leaganacha cruach dhosmálta, cuid acu atá brataithe le plaisteach garbh, freastal ar iarratais taobh amuigh agus timpeallachtaí guaiseacha.

Dearadh agus úsáid

Is éard atá sa cheangal cábla is coitianta ná téip níolón solúbtha le raca fearas comhtháite, agus ratchet ar cheann amháin laistigh de chás beag oscailte. Nuair a bheidh barr pointeáilte an chábla tarraingthe tríd an gcás agus anuas ar an ratchet, ní féidir é a tharraingt siar; the resulting loop may only be pulled tighter. Ligeann sé seo roinnt cáblaí a cheangal le chéile i mbeart cábla agus/nó crann cábla a dhéanamh.

A cable tie tensioning device or tool may be used to apply a cable tie with a specific degree of tension. Féadfaidh an uirlis an eireaball breise a shruthlú leis an chloigeann a ghearradh amach chun ciumhais ghéar a sheachaint a d’fhéadfadh díobháil a dhéanamh murach é. Light-duty tools are operated by squeezing the handle with the fingers, while heavy-duty versions can be powered by compressed air or a solenoid, to prevent repetitive strain injury.

In order to increase resistance to ultraviolet light in outdoor applications, nylon containing a minimum of 2% carbon black is used to protect the polymer chains and extend the cable tie's service life.[citation needed] Blue cable ties are supplied to the food industry and breiseán miotail a bheith iontu ionas gur féidir le brathadóirí miotail thionsclaíocha iad a bhrath

Stair

Ba é Thomas & Betts, cuideachta leictreach, a cheap ceangail cábla den chéad uair i 1958 faoin ainm branda Ty-Rap. Ar dtús bhí siad deartha le haghaidh úmacha sreinge eitleáin. The original design used a metal tooth, and these can still be obtained. D'athraigh na monaróirí go dtí an dearadh níolón/plaisteach níos déanaí.

Thar na blianta leathnaíodh an dearadh agus forbraíodh go leor táirgí seachthairbheacha é. Sampla amháin ab ea lúb féinghlasála a forbraíodh mar mhalairt ar uaim an tsreangáin in anastómóis na drólainne.

Ty-Rap cable tie inventor, Maurus C. Logan, worked for Thomas & Betts and finished his career with the company as Vice President of Research and Development. Le linn a thréimhse ag Thomas & Betts, chuir sé le forbairt agus margaíocht a lán táirgí rathúla Thomas & Betts. Fuair ​​Logan bás ar 12 Samhain 2007, in aois a 86 bliain.

The idea of the cable tie came to Logan while touring a Boeing aircraft manufacturing facility in 1956. Aircraft wiring was a cumbersome and detailed undertaking, involving thousands of feet of wire organized on sheets of 50-foot-long plywood and held in place with knotted, waxcoated, braided nylon cord. Each knot had to be pulled tight by wrapping the cord around one's finger which sometimes cut the operator's fingers until they developed thick calluses or “hamburger hands.” Bhí Logan cinnte go raibh bealach níos fusa, níos maithe ann chun an tasc ríthábhachtach seo a chur i gcrích.

Ar feadh na mblianta atá romhainn, rinne Logan turgnamh le huirlisí agus le hábhair éagsúla. Ar 24 Meitheamh, 1958, cuireadh isteach paitinn don cheangal cábla Ty-Rap.
