Abstract

A cover of a connector has axis portions and first and second cover contact points. A housing has axis receiving portions and first through third contact portions. The axis portions are received by the axis receiving portions, and the cover is attached to the housing to be placed at any one of an open position, a closed position and a locked position. The first contact portions are exposed in the axis receiving portions. When the cover is placed at the locked position, the axis portions are face the first contact portions from beneath, and the second cover contact points are face the second contact portions from beneath. When the cover is placed at the closed position, the first cover contact points do not touch the third contact portions. When the cover is placed at the locked position, the first cover contact points touch the third contact portions.

First claim

What is claimed is:

1. A connector which is mountable on a substrate, wherein:
the connector comprises a cover, a housing and a plurality of contact rows;
the housing has an accommodation portion which accommodates a card having a plurality of card contact points;
the housing is provided with two axis receiving portions and two lock portions;
the lock portions are located forward of the axis receiving portions in a front-rear direction;
the axis receiving portions are located apart from each other in a lateral direction perpendicular to the front-rear direction;
the lock portions are located apart from each other in the lateral direction;
the housing comprises an insulation portion and a frame;
the insulation portion holds the contact rows;
the insulation portion further holds the frame while the frame is exposed in part;
the frame comprises a single-piece member made of metal and has a plurality of fixed portions, two first contact portions, two second contact portions, a plurality of third contact portions and a plurality of support spring portions;
the first contact portions correspond to the axis receiving portions, respectively;
each of the first contact portions is exposed in the axis receiving portion corresponding thereto;
the second contact portions correspond to the lock portions, respectively;
the support spring portions have resilience and are located between the first contact portions and the second contact portions in the front-rear direction;
the third contact portions are supported by the support spring portions, respectively;
the third contact portions are movable at least in a direction perpendicular to the front-rear direction by using the resilience of the support spring portions;
the fixed portions are fixed to the substrate when the connector is mounted on the substrate;
at least one of the fixed portions is arranged between the first contact portions and the third contact portions in the front-rear direction;
at least another one of the fixed portions is arranged between the second contact portions and the third contact portions in the front-rear direction;
each of the contact rows is formed of a plurality of contacts which are arranged in the lateral direction;
each of the contacts has a contact point and a supporting portion;
the contact point is located in the accommodation portion;
the supporting portion has resilience and supports the contact point;
by using the resilience of the supporting portion, the contact point is movable at least in an up-down direction perpendicular to both of the front-rear direction and the lateral direction;
when the card is accommodated in the accommodation portion, the contact point is pressed downward in the up-down direction by one of the card contact points and receives an upward force given by a reaction force of the supporting portion;
the cover is made of metal and has a main portion, two axis portions, two first cover contact points, two locked portions and two second cover contact points;
the axis portions are located outward of the main portion in the lateral direction;
the axis portions are received by the axis receiving portions, respectively, so that the cover is attached to the housing so as to be positioned at any one of an open position, a closed position and a locked position;
the cover is pivotally movable between the open position and the closed position about the axis portions used as a pivotal axis;
the cover is movable between the closed position and the locked position in the front-rear direction;
when the cover is placed at the locked position, the main portion of the cover is positioned on or above an upper part of the housing and covers the accommodation portion;
when the cover is placed at the locked position, the axis portions are positioned downward of the first contact portions and face the first contact portions in the up-down direction, respectively;
the locked portions are positioned outward of the main portion in the lateral direction;
when the cover is placed at the locked position, the locked portions are positioned forward of the axis portions in the front-rear direction;
the second cover contact points are positioned outward of the main portion in the lateral direction;
when the cover is placed at the locked position, the second cover contact points are positioned downward of the second contact portions and face the second contact portions in the up-down direction, respectively;
when the cover is placed at the closed position, the first cover contact points are not brought into contact with the third contact portions; and
when the cover is placed at the locked position, the first cover contact points are brought into contact with the third contact portions, respectively.

2. The connector as recited in claim 1 , wherein:
when the card is accommodated in the accommodation portion and the cover is placed at the locked position, the locked portions are regulated by the lock portion not to be moved rearward in the front-rear direction; and
when the card is accommodated in the accommodation portion and the cover is placed at the locked position, the axis portions are brought into contact with the first contact portions, respectively, and the second cover contact points are brought into contact with the second contact portions, respectively.

3. The connector as recited in claim 1 , wherein when viewed along the up-down direction, the frame forms at least three sides of the accommodation portion.

4. The connector as recited in claim 1 , wherein the third contact portions are movable at least in the lateral direction.

5. The connector as recited in claim 1 , wherein by moving the cover placed at the closed position forward in the front-rear direction, the cover is shifted into the locked position.

6. The connector as recited in claim 1 , wherein:
the housing has two overhang portions overhanging rearward in the front-rear direction;
the lock portions are provided for the overhang portions, respectively; and
when the cover is moved from the closed position to the locked position, the locked portions are moved downward of the overhang portions in the up-down direction.

7. The connector as recited in claim 6 , wherein:
the lock portions protrude downward from the overhang portions in the up-down direction, respectively;
the second contact portions protrude downward from the overhang portions in the up-down direction, respectively;
the cover is provided with two tabs;
each of the tabs is provided with an aperture portion;
each of the locked portions is formed of an edge of the aperture portion; and
the second cover contact points are formed on upper surfaces of the tabs, respectively.
