Abstract

A terminal and an electrical connector are shown and the terminal has a tail, an elastic arm, a contact and a front guiding member. The elastic arm is connected to the tail. The contact is positioned at a distal end of the elastic arm. The contact has a front guiding surface extending forwards and downwards. The front guiding member extends forwards from the elastic arm. The front guiding member has a front guiding portion that extends forwards and downwards. An extending direction of the elastic arm and an extending direction of the front guiding member intersected at an angle. The front guiding portion is positioned in front of the front guiding surface of the contact.

First claim

What is claimed is:

1. A terminal, comprising:
a tail;
an elastic arm connected to the tail;
a contact positioned at a distal end of the elastic arm, the contact comprising a front guiding surface extending forwards and downwards; and
a front guiding member extending forwards from the elastic arm, the front guiding member having a front guiding portion extending forwards and downwards, wherein the elastic arm extends in a first direction and the front guiding member extends in a second direction, the first and second directions being at an angle to each other, the front guiding portion being positioned in front of the front guiding surface of the contact, wherein a highest position of the front guiding member is lower than a highest position of the contact and a lowest position of the front guiding surface of the contact is lower than the highest position of the front guiding member.

2. The terminal according to claim 1 , wherein the terminal further comprises a rear guiding member extending rearwards from the elastic arm, the rear guiding member comprises a rear guiding portion extending rearwards and downwards, the contact comprises a rear guiding surface extending rearwards and downwards, the rear guiding portion being positioned behind the rear guiding surface, a highest position of the rear guiding member being lower than the highest position of the contact and a lowest position of the rear guiding surface being lower than the highest position of the rear guiding member.

3. The terminal according to claim 2 , wherein the rear guiding member includes a connecting portion extending rearwards from the elastic arm and further includes a protruding portion protruding upwards and connected to the rear guiding portion.

4. The terminal according to claim 2 , wherein the contact is an arch top cover, a front surface of the arch top cover forms the front guiding surface, and a rear surface of the arch top cover forms the rear guiding surface.

5. The terminal according to claim 2 , wherein the extending direction of the elastic arm and an extending direction of the rear guiding member are intersected as an angle of 90°.

6. The terminal according to claim 1 , wherein the extending direction of the elastic arm and the extending direction of the front guiding member are intersected as the angle of 90°.

7. The terminal according to claim 1 , wherein the front guiding member comprises a connecting portion extending forwards from the elastic arm and a protruding portion protruding upwards and is connected to the front guiding portion.

8. An electrical connector, comprising:
an insulative housing comprising an upper surface;
a plurality of terminals fixed to the insulative housing, each of the plurality of terminals including a tail, an elastic arm connected to the tail, a front guiding surface extending forwards and downwards and a contact positioned at a distal end of the elastic arm, the contact protruding relative to the upper surface of the insulative housing and including; and
a front guiding member, extending forwards from the elastic arm, the front guiding member comprising a front guiding portion extending forwards and downwards, the front guiding portion protruding relative to the upper surface of the insulative housing, wherein the elastic arm extends in a first direction and the front guiding member extends in a second direction that intersects the first direction at an angle, the front guiding portion being positioned in front of the front guiding surface of the contact, a highest position of the front guiding member being lower than a highest position of the contact, a lowest position of the front guiding surface of the contact being lower than the highest position of the front guiding member, a lowest position of the front guiding member being lower than the upper surface of the insulative housing.

9. The electrical connector according to claim 8 , wherein each of the plurality of terminals comprises a rear guiding member extending rearwards from the elastic arm in a third direction, the rear guiding member of the each terminal including a rear guiding portion that extends rearwards and downwards, wherein the contact of each of the plurality of terminals includes a rear guiding surface that extends rearwards and downwards, and the rear guiding portion is positioned behind the rear guiding surface in the each terminal, wherein a highest position of the rear guiding member is lower than the highest position of the contact in the each terminal and a lowest position of the rear guiding surface is lower than the highest position of the rear guiding member in the each terminal.

10. The electrical connector according to claim 9 , wherein the rear guiding member of each of the plurality of terminals includes a connecting portion that extends rearwards from the elastic arm and a protruding portion that protrudes upwards and is connected to the rear guiding portion.

11. The electrical connector according to claim 9 , wherein the contact of each of the plurality of terminals is an arch top cover and a front surface of the arch top cover forms the front guiding surface, and a rear surface of the arch top cover forms the rear guiding surface.

12. The electrical connector according to claim 9 , wherein the first direction and the third direction are intersected at an angle of 90°.

13. The electrical connector according to claim 8 , wherein the first direction and the second direction are intersected at an angle of 90°.

14. The electrical connector according to claim 8 , wherein the front guiding member of each of the plurality of terminals includes a connecting portion that extends forward from the elastic arm and a protruding portion that protrudes upwards and is connected to the front guiding portion.
