Electrical connector having structure to pre-set solder balls
First Claim
1. An electrical connector comprising:
- an insulative housing having a top surface and a bottom surface opposite to each other and defining a plurality of passageways extending therethrough, the passageways each includes a solder ball receiving slot and a pre-setting slot below the solder ball receiving slot and communicated therewith;
a plurality of electrical contacts secured in the passageways respectively and each having a solder tail at a lower end thereof and a contact section at an upper end thereof; and
a plurality of solder balls contacting with the solder tails of the electrical contacts;
whereinthe pre-setting slot is expanded from the solder ball receiving slot, and the pre-setting slot restricts the solder ball at a first position and the solder ball receiving slot restricts the solder ball at a second position.

Abstract
An electrical connector includes an insulative housing with a number of passageways extending therethrough, a number of electrical contacts secured in the passageways respectively, and a number of solder balls contacting with the electrical contacts. The passageways each includes a solder ball receiving slot and a pre-setting slot below the solder ball receiving slot and expanded therefrom. The electrical contacts each have a solder tail at a lower end thereof and a contact section at an upper end thereof. The solder balls and the solder tails are disposed in the solder ball receiving slot and the pre-setting slot. The pre-setting slot restricts the solder ball at a first position and the solder ball receiving slot restricts the solder ball at a second position.

9. An electrical connector comprising:
-
an insulative housing having a top surface and a bottom surface opposite to each other and defining a plurality of passageways extending therethrough, the insulative housing having a first step and a second step below the first step in the passageway, the second step enlarging the passageway at a lower end thereof; a plurality of electrical contacts secured to the passageways respectively and each having a solder tail at a lower end thereof and a contact section at an upper end thereof; and a plurality of solder balls contacting with the solder tails of the electrical contacts;
whereinthe solder tail and the second step support the solder ball at a first position, and the solder tail and the first step position the solder ball at a second position. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An electrical connector comprising:
-
an insulative housing with a plurality of passageways extending therethrough in a vertical direction between two opposite upper and bottom surfaces; a plurality of terminals into the corresponding passageways, respectively, each of said terminal including an upper mating section extending upwardly above the upper surface, and a lower mounting section around the bottom surface; and a plurality of solder balls upwardly inserted into the corresponding passageways, respectively;
whereina bottom portion of each passageway and the lower mounting section of each corresponding terminal are configured to commonly define therebetween, in a transverse direction perpendicular to said vertical direction, a receiving cavity under condition that said receiving cavity defines opposite upper and lower receiving spaces in the vertical direction so as to allow the corresponding solder ball to be temporarily held in a lower receiving space at an initial stage during insertion of the solder ball into the corresponding passageway for easing pre-assembling of the solder ball with regard to the housing and the corresponding terminal, and to be permanently held in the upper receiving space at a final stage for assuring engagement among the solder ball, the housing and the terminal. - View Dependent Claims (17, 18, 19, 20)
