Abstract

A female connector has a plurality of contacts to be connected to a card member having a card edge portion with a plurality of card edge terminals formed on a substrate, and a housing disposed with contact housing portions, and the housing has a flat opening portion on one side into which the card edge portion is inserted, an insertion port on the other side, and an inner space therein communicating with the flat opening portion and disposed with the card edge portion, and the contact housing portion has at least two stages of first contact housing portions formed on one side relative to the inner space of the housing and communicating with the insertion port, and a stage of second contact housing portions formed on the other side relative to the inner space of the housing and communicating with the insertion port.

First claim

What is claimed is:

1. A female connector, comprising: a housing disposed with a plurality of contacts to be connected to a card member having a card edge portion with a plurality of card edge terminals formed on a substrate, wherein the housing includes contact housing portions that house the contacts,
the housing having a flat opening portion

into which the card edge portion is inserted on one side, an insertion port through which a wire is inserted on the other side, and an inner space therein, the inner space communicating with the flat opening portion and acting as a portion in which the card edge portion is located,
the contact housing portions are arranged as at least two stages of first contact housing portions formed on one side relative to the inner space of the housing, the first contact housing portions communicating with the insertion port, and one stage of second contact housing portions formed on the other side relative to the inner space of the housing, the second contact housing portions communicating with the insertion port, wherein the first contact housing portions are made up of inner contact housing portions disposed adjacently to the inner space and at least one stage of outer contact housing portions disposed on the outside of the inner contact housing portions, the second contact housing portions are made up of another inner contact housing portions disposed adjacently to the inner space, the respective inner contact housing portions of the first contact housing portions and the another inner contact housing portions of the second contact housing portions are disposed oppositely to each other, the inner contact housing portions house first contacts to be directly connected to the card edger terminals while the outer contact housing portions house second contacts, the second contacts are coupled to relay terminals made of conductive material, and the relay terminals are extended in the inner space to be connected to the card edge terminals.

2. The female connector of claim 1 , wherein the first contact housing portions are formed on three stages.

3. The female connector of claim 1 , wherein the housing has relay terminal housing portions formed to be in communication with the outer contact housing portions, and the relay terminal housing portions house the relay terminals.

4. The female connector of claim 3 , wherein
the housing is divided into a contact housing on the side disposed with the contact housing portions and a relay terminal housing on the side disposed with the relay terminal housing portions, and
the contact housing and the relay terminal housing are detachably connected.

5. The female connector of claim 4 , wherein
the first contact has a first connecting portion connected to the card edge terminal on one side formed integrally with a first wire mounting portion mounted with the wire on the other side,
the first connecting portion is formed into a hollow cylindrical body having a first front-side opening formed on the inner space side of the contact housing when the first contact is attached to the inner contact housing portion, a first rear-side opening formed on the first wire mounting portion side, and a first contacting portion brought into contact with the card edge terminal,
the inner contact housing portion of the contact housing is covered by side wall portions formed on the sides of both side surfaces of the housed first contact and an end wall portion formed on the first front-side opening side,
the first contact is opened at least at a portion provided with the first contacting portion, and
a protruding portion fitted into the first front-side opening of the first connecting portion is formed on the side of the end wall portion opposite to the first contact.

6. The female connector of claim 5 , wherein the end wall portions formed in the contact housing are formed to be respectively integrally linked on one side and the other side across the inner space of the contact housing.

7. The female connector of claim 4 , wherein
the second contact has on one side a coupling portion to which the relay terminal is inserted and coupled and formed integrally with a second wire mounting portion to be mounted with the wire on the other side,
the coupling portion formed into a hollow cylindrical body having a second front-side opening formed on the flat opening portion side when the second contact is attached to the relay terminal housing, and a second rear-side opening formed on the second wire mounting portion side, and
a second contacting portion is disposed inside the coupling portion and brought into contact with a portion of the relay terminal when the relay terminal is coupled.

8. The female connector of claim 1 , wherein the housing has at least one rib formed to link the upper side and the lower side of the inner space.

9. The female connector of claim 1 , wherein
the housing is mounted with a lid body covering the relay terminals and having an opening at least at a portion corresponding to the flat opening portion, and
the lid body has a pressing portion pressing, positioning, and fixing a portion of the relay terminals.

10. The female connector of claim 1 , wherein the relay terminal has a relay terminal main body made up of a bent plate-like body, a second connecting portion formed on one side of the relay terminal main body and connected to the card edge terminal, and a coupling piece inserted from the second front-side opening of the coupling portion which is formed on the other side of the relay terminal main body, coupled in the coupling portion of the second contact, and brought into contact with the second contacting portion in the coupling portion.

11. A card edge connector, comprising:
a card member to be connected to a female connector including: a housing disposed with a plurality of contacts to be connected to the card member having a card edge portion with a plurality of card edge terminals formed on a substrate, wherein the housing includes contact housing portions that house the contacts; the housing having a flat opening portion into which the card edge portion is inserted on one side, an insertion port through which a wire is inserted on the other side, and an inner space therein, the inner space communicating with the flat opening portion and acting as a portion in which the card edge portion is located; the contact housing portions are arranged as at least two stages of first contact housing portions formed on one side relative to the inner space of the housing, the first contact housing portions communicating with the insertion port, and one stage of second contact housing portions formed on the other side relative to the inner space of the housing, the second contact housing portions communicating with the insertion port; and
the substrate having at least two rows of card edge terminals on one surface of the substrate and one row of card edge terminals on the other surface thereof,
the card edge portion having a slit disposed at least at one location.

12. The card edge connector of claim 11 , wherein
the card member includes a card housing to be connected to the housing of the female connector,
the card housing has a substrate insertion hole formed at a position corresponding to the flat opening portion of the female connector, and the card edge portion of the card member is projected from the substrate insertion hole.

13. The card edge connector of claim 12 , wherein the female connector is disposed with a lock mechanism fixing the state of connection to the card housing.
