Abstract
A cable 1 is configured of connecting portions 12 on both ends for connecting to external connecting terminals and an intermediate portion 13. Each connecting portion 12 has electroconductive portions 14 for connecting with external connecting terminals. The cable 1 is formed by layering multiple elastomer sheets 1H. Each elastomer sheet 1H is formed with an elastomer raw material having no electroconductivity as a base, with rectangular elastomer regions 1T having electroconductivity on both ends and transmission paths for connecting the rectangular elastomer regions 1T on both ends.
Claims7
A cable, comprising:
- a cable body including a plurality of elastomer sheets having non-electroconductivity, each of said elastomer sheets having a pair of wide ends and a narrow intermediate portion integrally connected to and provided between the ends;
- m rows of rectangular elastomer regions having electroconductivity being arrayed on each of the pair of said wide ends, each one of the rectangular elastomer regions forming a rectangular bar member embedded into a respective leading end portion of the pair of wide ends;
- and
- k patterns (wherein k is a number equal to or less than m) of transmission paths connecting said rectangular elastomer regions by extending between connected ones of the transmission paths of respective ones of the rectangular elastomer regions through said narrow intermediate portion;
- wherein n layers (wherein n is a number equal to or less than m) of said plurality of elastomer sheets are layered such that the rectangular elastomer regions of the upper and lower layers are mutually in contact, and connected with said external connecting terminals by pressuring said external connecting terminals against both ends of said elastomer sheets which have been layered.
A manufacturing method for a cable, comprising:
- an electroconductive portion formation step for providing electroconductive elastomer on a non-electroconductive elastomer member formed in the shape of said cable so as to obtain an elastomer member;
- a cutting step for cutting said elastomer member into sheets to obtain elastomer sheets;
- a transmission path formation step for forming transmission paths on the surface of said elastomer sheets;
- and
- a sheet layering step for layering and adhering said plurality of elastomer sheets to form a cable body having opposing leading end portions of the non-electroconductive elastomer member with bar-shaped portions of the electroconductive elastomer being embedded into respective ones of the opposing leading end portions.
