Abstract

A contact for being received in an electrical socket which interconnects an integrated circuit (IC) package with a printed circuit board (PCB), comprises a contact portion for electrically connecting with a pin of the IC package, a locating portion for interferentially engaging with insulative housing of the electrical socket, and a tail portion having a plurality of clip arms. When a solder block is inserted into the tail portion, the clip arms can deflect to secure the solder block in a predetermined position in the tail portion.

Claims

1. A contact for being received in an electrical socket which interconnects an integrated circuit (IC) package with a printed circuit board (PCB), the contact comprising:

a contact portion for electrically connecting with a pin of the IC package;

a locating portion extending from the contact portion for interferentially engaging with an insulative housing of the electrical socket; and

a tail portion extending from a lower end of the locating portion with a plurality of clip arms extending generally in a horizontal domain;

wherein

when a solder block is engaged with the tail portion, the clip arms are deflectable in said domain to secure the solder block in a predetermined position in the tail portion.

2. The contact as described in claim 1, wherein the contact has a connection portion for connecting the location portion with the tail portion.

3. The contact as described in claim 2, wherein the connection portion has an opening formed therein to prevent solder wicking.

4. The contact as described in claim 2, wherein the clip arms of the tail portion form a ring-shaped section therebetween to secure the solder block therein.

5. The contact as described in claim 2, wherein the clip arms of the tail portion have two substantially parallel portions which are deflectable to secure the solder black therebetween.

6. The contact as described in claim 2, wherein the clip arms of the tail portion comprises two L-shaped arms, a third clip arm extends perpendicular to the two L-shaped arms, and wherein the solder block is securable in a space defined among the three clip arms.

7. The contact as described in claim 2, wherein the clip arms of the tail portion have two recesses formed therein for accommodating and engagingly receiving the solder block.

8. A contact including a locating portion, a resilient contact portion extending upwardly from said locating portion, a connection portion downwardly extending from said locating portion, and a horizontal tail portion perpendicularly extending generally in a horizontal domain from a lower end of said connection portion with radial expansibility thereof and defining therein an opening extending therethrough in a vertical direction, and a solder block forcibly inserted into said opening and retained by said tail portion.

9. The contact as described in claim 8, wherein said solder block is exposed on two opposite upper and lower sides of a plane defined by said tail portion.
