Abstract
A contact includes an upper contact having a planar main board with a plurality of blocks, a lower contact, and a spring. The lower contact includes a first spring arm and a second spring arm which are positioned at opposite sides of the main board of the upper contact. Only the second spring arm defines a recess to receive corresponding block of the upper contact. The spring is fitted over a predetermined area between the upper and the lower contact.
Claims16
A contact comprising:
- an upper contact having a planar main board with a plurality of blocks;
- a lower contact including a first spring arm and a second spring arm extending upwardly and away from each other, the first spring arm and the second spring arm positioned at opposite sides of the main board of the upper contact, and the first spring arm being split from the second spring arm to form a recess to receive corresponding block of the upper contact;
- and
- a spring fitted over a predetermined area between the upper and the lower contact;
- wherein the second spring arm is configured into a loop to form the recess thereof and the recess has a shape substantially the same with the first spring arm.

A contact unit for use within an electrical connector, comprising:
- a first contact defining essentially a planar main board defining two opposite main surfaces thereof with two block structures respectively formed on the corresponding two opposite main surfaces;
- a second contact defining a pair of spring arms respectively abutting against on said two main surfaces so as to commonly sandwich the planar main board of the first contact therebetween, said pair of spring arms defining a pair of stopping structures at free ends respectively for engagement with the corresponding two block structures, respectively;
- and
- a spring having two ends respectively acting upon the first contact and the second contact for constantly urging the first contact and the second contact to move away from each other;
- wherein
- the first contact defines a larger thickness than the second contact and defines variant thicknesses at different positions while the second contact is stamped from sheet metal with essentially a constant thickness smaller than that of the first contact under condition that the pair of spring arms are split from each other and one of the pair of spring arms defines a single contact point with the corresponding main surface while the other of the pair of spring arms defines a pair of contact points with the corresponding main surface, the first spring arm and the second spring arm being bent away from each other to make a space therebetween for receiving the main board of the first contact.

- a spring having two ends respectively acting upon the first contact and the second contact for constantly urging the first contact and the second contact to move away from each other;
- wherein
- the first contact defines a first contact portion at a distal end opposite to the second contact, and the second contact defines a second contact portion at a distal end opposite to the first contact, said second contact portion defining a thickness direction which is perpendicular to the two main surfaces.
