Abstract

In the disclosed electrical connector, the card inserted from the inlet is moved, together with the slider abutting against this card, in a state being inclined to the specified placing plane, resisting the thrusting force to the inlet side by the thrusting means, and when this card and slider reach the specified position, the card and slider are oscillated about the oscillating fulcrum part to position them on the specified placing plane, thereby causing the contact formed on the contact piece part of the conductor piece to contact elastically with the contact of the card, while fixed the slider on the specified placing plane by the lock mechanism.

Claims

1. An electrical connector comprising:

an inlet opened in a housing for inserting and removing a card having contacts;

a slider which is engaged with the card inserted in this inlet and moves in a state inclined with respect to a specified placing plane by pushing the engaged card;

thrusting means for thrusting this slider to said inlet side;

an oscillating fulcrum part for oscillating the slider moved to the inner side of said inlet so as to position on said specified placing plane;

a lock mechanism for fixing the slider positioned on said specified placing plane on this placing plane; and

contacts formed in a contact piece part of a conductor piece having a spring action, and disposed at a position of elastically touching the contacts of the card engaged with the slider when said slider is positioned on said placing plane.

2. The electrical connector of claim 1, wherein guide paths inclined toward said placing plane are disposed at both sides of the slider, guide protuberances to be inserted into said guide paths are formed on said slider, a key unit is consecutively formed next to the terminal end of the guide paths to allow to insert the guide protuberances, whereby said slider can be moved with respect to the placing plane as said guide protuberances move along the guide paths, and the lock mechanism fixes the slider on the placing plane by holding said guide protuberances at the lock position of said key unit by the thrusting means.

3. The electrical connector of claim 2, wherein the key unit is shaped in an L-form bent toward the starting end side of said guide paths, and has a lock position to be engaged with said gudie protuberance at the terminal end thereof.

4. The electrical connector of claim 2, wherein the key unit is shaped in a rectangular form, and said guide protuberances are held in the lock position by pressing the guide protuberances against the peripheral wall at the lock position of this key unit by the thrusting means.

5. The electrical connector of claim 3, wherein the guide paths and key unit are guide holes and key hole pierced in the side wall of the housing.

6. The electrical connector of claim 4, wherein the guide paths and key unit are guide holes and key hole pierced in the side wall of the housing.

7. The electrical connector of claim 3, wherein the guide paths and key unit are guide grooves and key groove provided in the side wall of the housing.

8. The electrical connector of claim 7 comprising a feedback groove which is disposed consecutively to the terminal end of said key groove by way of a convex part and is converged with said guide groove adhead of the terminal end of this key groove, and having said guide protuberances as protrusions with various projections thrust to the projection side, wherein fixing of the slider by said lock mechanism is released by inserting the guide protuberances into said feedback groove through said convex part and bringing them up to the starting end part of the guide groove through the feedback groove by said thrusting means.

9. The electrical connector of claim 1, wherein the lock mechanism possesses an engaging protuberance formed on the side face of the slider, and an engaging piece to be engaged with said engaging protuberance when said slider is positioned on the placing plane, being able to elastically deform in the direction of departing from the side face of the slider by means of said engaging protuberance.

10. The electrical connector of claim 5, wherein the contacts are formed in the top of the contact piece part bent in a V-form.

11. The electrical connector of claim 7, wherein the contacts are formed in the top of the contact piece part bent in a V-form.

12. The electrical connector of claim 8, wherein the contacts are formed in the top of the contact piece part bent in a V-form.

13. The electrical connector of claim 9, wherein the contacts are formed in the top of the contact piece part bent in a V-form.

14. The electrical connector of claim 10, wherein the slider is a tray having the peripheral wall to abut against the card inserted from said inlet formed at the rear end side, the thrusting means is a compression spring stretched between the spring receptacble which is integral with said housing and said tray, and an oscillating fulcrum part of a semicircular section abutting against the integral part with the housing when the guide protuberance reaches the terminal end of said guide path is projected at the back side of the bottom of said tray.

15. The electrical connector of claim 11, wherein the slider is a tray having the peripheral wall to abut against the card inserted from said inlet formed at the rear end side, the thrusting means is a compression spring stretched between the spring receptacble which is integral with said housing and said tray, and an oscillating fulcrum part of a semicircular section abutting against the integral part with the housing when the guide protuberance reaches the terminal end of said guide path is projected at the back side of the bottom of said tray.

16. The electrical connector of claim 12, wherein the slider is a tray having the peripheral wall to abut against the card inserted from said inlet formed at the rear end side, the thrusting means is a compression spring stretched between the spring receptable which is integral with said housing and said tray, and an oscillating fulcrum part of a semicircular section abutting against the integral part with the housing when the guide protuberance reaches the terminal end of said guide path is projected at the back side of the bottom of said tray.

17. The electrical connector of claim 13, wherein the slider is a tray having the peripheral wall to abut against the card inserted from said inlet formed at the rear end side, the thrusting means is a compression spring stretched between the spring receptable which is integral with said housing and said tray, and an oscillating fulcrum part of a semicircular section abutting against the integral part with the housing when the guide protuberance reaches the terminal end of said guide path is projected at the back side of the bottom of said tray.
