Abstract
A plug connector 200 configured to be inserted in a host connector 100 includes a plurality of contact pins aligned in a predetermined direction and a housing 210 configured to hold the plurality of contact pins. Each of the contact pins extends in an intersecting direction that is a direction intersecting the predetermined direction, and the housing 210 includes pin grooves 212a provided in the surface thereof, extending in the intersecting direction, and configured to accommodate the contact pins and includes holes 212b provided aligned with the pin grooves 212a in the intersecting direction and recessed deeper than the pin grooves 212a from the surface.
Claims5
A plug connector configured to be inserted in a host connector, the plug connector comprising:
- a plurality of contact pins aligned in a predetermined direction;
- and
- a housing configured to hold the plurality of contact pins,
- wherein each of the contact pins extends in an intersecting direction that is a direction intersecting the predetermined direction, and
- wherein the housing includes at least one groove provided in a surface of the housing, extending in the intersecting direction, and each configured to accommodate each of the contact pins and includes at least one hole provided aligned with the groove in the intersecting direction and recessed deeper than the groove from the surface.
A housing for a plug connector, the housing comprising:
- a base part;
- and
- a protruding part protruding in one direction from the base part and configured to be inserted in a host connector,
- wherein the base part includes insertion holes used for insertion of contact pins,
- wherein the protruding part includes grooves used for accommodation of the contact pins,
- wherein each of the grooves is provided in a surface of the protruding part, extends in the one direction, and corresponds to each of the insertion holes of the base part, and
- wherein the protruding part includes, at an end of the base part side, holes provided aligned with the grooves in the one direction and recessed deeper than the grooves from the surface.
A manufacturing method of a housing for a plug connector using a mold,
- wherein a closed space is defined inside the mold when a stationary piece, slide pieces, and a movable piece are engaged with each other,
- wherein the movable piece includes a plurality of core pins for forming insertion holes used for insertion of contact pins in the housing, and
- wherein the slide piece includes a plurality of groove formation parts for forming grooves used for accommodation of the contact pins in the housing, protrusions provided to the groove formation parts and protruding in a direction in the closed space beyond the groove formation parts, and fitting recesses formed in faces of the protrusions facing the movable piece,
- the manufacturing method comprising:
- a fitting step of fitting tip portions of the core pins of the movable piece into the fitting recesses of the slide pieces when the slide pieces and the movable piece are engaged with each other;
- a resin injection step of injecting a liquid resin in the closed space defined by engagement of the stationary piece, the slide pieces, and the movable piece;
- and
- a resin solidification step of cooling and solidifying the resin injected to the closed space.
