Unipolar terminal block having a slipping-prevention portion
A unipolar terminal block includes a terminal having a first connection portion formed at one end side, a second connection portion formed at the other end side, and a central portion formed in a cylinder shape; and a resin portion holding the central portion of the terminal, wherein the resin portion includes a holding hole having a circular cross section and through which the central portion of the terminal is passed, and a slipping-prevention portion engaging with the central portion of the terminal, and the terminal is held to be rotatable with respect to the resin portion.
1 . A unipolar terminal block, comprising:
a terminal having a first connection portion formed at one end side, a second connection portion formed at the other end side, and a central portion formed in a cylinder shape; and
a resin portion holding the central portion of the terminal,
wherein the resin portion includes a holding hole having a circular cross section and through which the central portion of the terminal is passed, and a slipping-prevention portion engaging with the central portion of the terminal, and
the terminal is held to be rotatable with respect to the resin portion.
2 . The unipolar terminal block according to claim 1 ,
wherein the slipping-prevention portion is an annular rib protruding from an inner circumferential surface of the holding hole, and
an annular groove with which the slipping-prevention portion is engaged is formed on an outer circumferential surface of the central portion of the terminal.
3 . The unipolar terminal block according to claim 1 , further comprising a cylindrical collar that is held by the resin portion.
4 . A manufacturing method for the unipolar terminal block according to claim 1 , comprising:
molding the terminal and the resin portion individually; and
press-fitting and assembling the terminal into the holding hole of the resin portion.
5 . A manufacturing method for the unipolar terminal block according to claim 1 , comprising:
applying a lubricant to the terminal that is molded in advance;
setting the terminal to which the lubricant is applied into a cavity of a mold unit for molding the resin portion; and
filling molten resin into the cavity to mold the resin portion.
