Electrical connector

1. An electrical connector comprising;

a housing made of insulator to be mounted on a solid circuit board and provided thereon with an opening through which a flat circuit device is inserted into the housing,

a plurality of conductive contacts arranged on the housing to be electrically connected respectively with circuit terminals provided on the solid circuit board and positioned to correspond respectively to connecting terminals provided on the flat circuit device inserted in the housing through the opening provided thereon, and

a holding member attached to the housing to be operative to hold the flat circuit device inserted in the housing through the opening provided thereon and then to release the flat circuit device from holding by the holding member,

wherein the holding member has a base portion provided to be fixed to the housing and a movable arm portion extending from the base portion, and the movable arm portion is provided thereon with an engaging portion operative to be put in engagement with the flat circuit device inserted in the housing so as to hold the same and a releasing portion protruding from the movable arm portion to the outside of the housing and is operative to move for releasing the engaging portion from the engagement with the flat circuit device when the releasing portion is manipulated to be shifted in position.

2. An electrical connector according to claim 1 , wherein the holding member is made of metallic material to have a board connecting portion provided for extending from the base portion to the outside of the housing to be soldered to a conductive portion provided on the solid circuit board on which the housing is mounted.

3. An electrical connector according to claim 1 , wherein an end portion of each of the conductive contacts projects from one of end portions opposite to each other of the housing to the outside of the housing to be soldered to a circuit terminal provided on the solid circuit board on which the housing is mounted and the board connecting portion of the holding member projects from the other of end portions opposite to each other of the housing to the outside of the housing to be soldered to the conductive portion provided on the solid circuit board on which the housing is mounted.

4. An electrical connector according to claim 1 , wherein a depression is formed at a part of an external surface portion of the housing from which the releasing portion provided on the movable arm portion of the holding member protrudes to the outside of the housing.

5. An electrical connector according to claim 1 , wherein the movable arm portion of the holding member is connected through a holding-back portion with the base portion so as to be operative to swing for getting near to or away from the base portion and provided thereon with a contacting portion extending from the holding-back portion to operative to come into contact with the housing.

6. An electrical connector according to claim 1 , wherein the engaging portion of the holding member has a slanted end plane formed thereon to ascends gradually in a direction along which the flat circuit device is inserted into the housing through the opening provided thereon and a part of the engaging portion on which the slanted end plane is formed is operative to engage with the flat circuit device inserted in the housing.

7. An electrical connector according to claim 1 , wherein a couple of holding members are attached respectively to both end portions of the housing aligned in a direction along which the conductive contacts are arranged.
