Abstract

A hood assembly attached to a female connector includes slide members on the top and bottom thereof which are slid in a direction perpendicular to a fitting direction of male and female connectors. As a result of a movement of the slide members, guide pins provided on the male connector is guided by guide grooves provided on the slide members to pull the male connector into the hood assembly, thereby fitting the connectors to each other. A hood portion of the female connector is inserted between upper and lower flanges of the hood assembly with anchoring holes provided on the hood assembly and anchoring projections provided on the female connector in positions shifted from each other, and the hood assembly and the female connector are slid in this state into a normal position where the anchoring projections engage the anchoring holes.

Claims4

Dependent claims

A connector fitting structure for connecting first and second connectors using a hood assembly, comprising:

the first connector having guide pins formed on an upper and lower surface for connecting the first connector to the hood assembly;
the second connector having a hood portion, wherein anchoring projections are formed on an upper and lower inner surface of the hood portion;
the hood assembly comprising a hood having a first opening connectable to the first connector and a second opening connectable to the second connector, wherein the first opening has an upper and lower surface defining notches therein for receiving the guide pins of the first connector, and wherein the second opening has flanges provided on an upper and lower surface defining a displacement regulating portion, and wherein the second opening has anchoring tabs projecting therefrom for connecting to the second connector anchoring projections, wherein the anchoring tabs are formed at a predetermined interval from the flanges, and wherein the anchoring tabs define anchoring holes therethrough for receiving the anchoring projections, the anchoring projections insertable between the flanges and the anchoring tabs;
a first and second slide member slidably connected to the hood, the slide members having guide grooves disposed therein for receiving the guide pins of the first connector, the guide grooves corresponding to the first opening notches, wherein the first slide member is slidable in an opposite direction from the second slide member;
and
an operating lever having a lever portion and a pivoting portion, the pivoting portion pivotally attached to the hood, wherein the pivoting portion has an upper and a lower end, wherein the upper end is connected to the first slide member and the lower end is connected to the second slide member wherein movement of the lever portion causes the first slide member to move in one direction and the second slide member to move in an opposite direction thereby defining a cam mechanism;
and
wherein the first and second connectors are engagable by the cam mechanism by pivotal movement of the operating lever when the guide pins are engaged with the guide grooves.

5 more elements

A connector fitting method for fitting first and second connectors to each other using a hood assembly, comprising the steps of:

inserting a hood portion of said second connector between flanges provided at a first opening of said hood assembly on an upper and lower surface defining a displacement regulating portion and an anchoring tab formed on said first opening of said hood assembly with a predetermined interval from said flanges;
moving said hood assembly in a direction intersecting a mutually engaged direction of said hood portion between said flanges and said anchoring tab, and to expand a gap between said flanges and said anchoring tab;
moving said hood assembly further in the direction intersecting the mutually engaged direction of said first and said second connectors to insert an anchoring projection formed on said first and said second connectors to engage said anchoring projection of said second connector with said anchoring tab, said anchoring tab defining an anchoring hole therein;
and
causing relative movement between a first and a second slide member provided on said hood assembly movable relative to each other in the direction intersecting the mutually engaged direction for moving said first and second connectors in the mutually engaged direction to fit said first and second connectors to each other with a cam mechanism,
wherein said cam mechanism is defined by an operating lever having a lever portion and a pivoting portion, said pivoting portion pivotally attached to a hood on said hood assembly, wherein said pivoting portion has an upper end and a lower end, wherein said upper end is connected to said first slide member and said lower end is connected to said second slide member, wherein movement of said lower portion causes said first slide member to move in one direction and said second slide member to move in an opposite direction and wherein said first and second connectors are engagable by said cam mechanism by pivotal movement of said operating lever when first connector guide pins are engaged with slide member guide grooves.
