Abstract
An electrical connector and a terminal are disclosed. The terminal, comprising: a base having an upper end and a lower end; a flexible arm extending upward from the upper end of the base; a retaining portion extending upward from the upper end of the base, wherein a first predetermined distance is between the flexible arm and the retaining portion; a pair of holding legs, each one comprising: a transition arm extending downward from the lower end of the base and a welding portion extending downward from the transition arm; wherein a second predetermined distance is between two transition arms, two welding portions are co-planner and inclined to the base.
Claims18
A terminal, received in a receiving slot of an insulating housing, comprising:
- a base having an upper end and a lower end;
- a flexible arm extending upward from the upper end of the base;
- a retaining portion extending upward from the upper end of the base, wherein a first predetermined distance is between the flexible arm and the retaining portion;
- a pair of holding legs, each holding leg comprising:
- a transition arm extending obliquely and downward from the lower end of the base and
- a welding portion extending downward from the transition arm at a slanting angle;
- wherein a second predetermined distance is defined between the two transition arms, wherein the pair of welding portions are co-planner and inclined toward the base;
- wherein the pair of welding portions form a retaining space therebetween to retain a solder ball;
- and wherein each of the welding portions is respectively formed with a substantially arc-shaped inner edge, wherein the inner edges between the two welding portions of the holding legs define a claw structure to retain the solder ball with the insulating housing.
An electrical connector, comprising:
- an insulating housing having a plurality of receiving slots, wherein the receiving slots are disposed in a staggered configuration;
- a plurality of terminals, received in the receiving slots correspondingly, and each of the terminals comprising:
- a base having an upper end and a lower end;
- a flexible arm extending upward from the upper end of the base;
- and
- a retaining portion extending upward from the upper end of the base, wherein a first predetermined distance is between the flexible arm and the retaining portion;
- and
- a pair of holding legs, each holding leg comprising:
- a transition arm extending obliquely and downward from the lower end of the base;
- and a welding portion extending downward from the transition arm at a slanting angle with respect to the transition arm;
- wherein a second predetermined distance is defined between the two transition arms, wherein the free end of the flexible arm of the terminal in a row is situated between two adjacent flexible arms of the corresponding terminals in a front adjacent row;
- wherein the pair of welding portions form a retaining space therebetween to retain a solder ball;
- and wherein the insulating housing protrudes a plurality of protrusion portions from a bottom surface thereof adjacent to the receiving slots correspondingly and faces toward the welding portions correspondingly, wherein each one of the protrusion portions and each two welding portions define a secure holding structure to hold firmly the solder ball there between.
