Terminal group and connector
A terminal group includes: a plurality of pin terminals, each pin terminal being formed of a metal wire of a predetermined length and being to be press-fitted and held in each of a plurality of terminal insertion holes of a connector housing. Some of the plurality of pin terminals have different overall lengths. The plurality of pin terminals respectively have a pair of press-fitting supports that protrude from both side edges of each of the plurality of pin terminals in a width direction at the same distant positions from a distal end in an insertion direction, and insertion direction rear end side surfaces of the press-fitting supports receive reaction force with respect to the terminal insertion holes in press-fitting.
1. A terminal group comprising:
a plurality of pin terminals, each pin terminal being formed of a metal wire of a predetermined length and being configured to be press-fitted and held in each of a plurality of terminal insertion holes of a connector housing, wherein
some of the plurality of pin terminals have different overall lengths,
the plurality of pin terminals respectively have a pair of press-fitting supports that protrude from both side edges of each of the plurality of pin terminals in a width direction at the same distant positions from a distal end in an insertion direction, and
insertion direction rear end side surfaces of the press-fitting supports receive a reaction force of an insertion tool with respect to the terminal insertion holes in press-fitting to urge the pin terminals into the terminal insertion holes.
2. The terminal group according to claim 1 , wherein
at least a pair of press-fitted sections are formed closer to a front end side of the insertion direction of the pin terminal than the press-fitting supports, and wherein the press-fitted sections protrude from both side edges of the pin terminal in the width direction thereof, and
the pair of press-fitted sections are configured to be press-fitted and held in the terminal insertion hole.
3. The terminal group according to claim 2 , wherein
a non-plastic forming-processed surface where plastic forming is not performed on a terminal surface of the pin terminal is provided, in at least one of a region or a part of the region between the pair of the press-fitting supports and a region or a part of the region between the pair of press-fitted sections.
4. The terminal group according to claim 3 ,
wherein the non-plastic forming-processed surface is connected to the terminal surface by a tapered flat surface having a width which is gradually widened.
5. The terminal group according to claim 2 , wherein
the pin terminal has a plurality of the pairs of press-fitted sections which are formed at intervals in the insertion direction, and
the plurality of the pairs of press-fitted sections are provided at different positions from each other in a height direction orthogonal to the width direction of the pin terminal.
6. The terminal group according to claim 1 , wherein
the metal wire from which the pin terminal is formed is plated.
7. A device comprising:
the connector housing,
a connector housing,
a plurality of pin terminals, each pin terminal being formed of a metal wire of a predetermined length and being configured to be press-fitted and held in each of a plurality of terminal insertion holes of the connector housing, wherein
some of the plurality of pin terminals have different overall lengths,
the plurality of pin terminals respectively have a pair of press-fitting supports that same distant positions from a distal end in an insertion direction, and
insertion direction rear end side surfaces of the press-fitting supports receive a reaction force of an insertion tool with respect to the terminal insertion holes in press-fitting to urge the pin terminals into the terminal insertion holes of the connector housing.
8. The terminal group according to claim 1 , wherein the pair of press-fitting supports are located outside of the connector housing when the plurality of pin terminals are held in the plurality of terminal insertion holes of the connector housing.
