Abstract

A compression connector for mounting to a print circuit board includes an insulative housing and a plurality of terminals received in the housing. The housing includes a first mating surface and a second mating surface opposite to the first mating surface. A number of terminal passageways are disposed between and running through the first and second mating faces. Each terminal includes a retaining section. Each of terminal passageway defines a retaining slot along a height direction orienting from the first mating surface to the second mating surface to receive the retaining section of the terminal and two limited portions at two ends of the retaining slot in the height direction so as to allow the retaining section to move in the height direction without dropping out.

Claims

1. A compression connector comprising:

an insulative housing defining a first mating surface and a second mating surface opposite to the first mating surface and defining a plurality of passageways disposed between and running through the first and second mating faces; and

a plurality of terminals received and retained in the passageways, each of the terminal comprising a retaining section, two spring sections each with a contacting section thereof projecting outwards the first and second mating surfaces respectively;

wherein the passageway defines retaining slots along a height direction orienting from the first mating surface to the second mating surface to receive the retaining sections of the terminals and two limited portions at two ends of the retaining slots in the height direction to prevent the retaining sections from dropping out of the retaining slots in the height direction wherein the retaining section is shorter than the retaining slot in the height direction;

wherein the passageways are divided into two rows extending along a longitudinal direction of the insulative housing, the two rows of contacting sections orient in opposite directions;

wherein the insulative housing comprises a first housing and a second housing combining with the first housing, the first housing defines a first contacting surface opposite to the first mating surface and the second housing defines a second contacting surface opposite to the second mating surface, the retaining slots of the passageways are defined running through the first and second contacting surfaces respectively, while not through the first and second mating surfaces.

2. The compression connector as claimed in claim 1, wherein the two spring sections of each terminal extend symmetrically from an upper and lower portions of the retaining section and are located as a same side of the retaining section.

3. The compression connector as claimed in claim 2, wherein each passageway has an inner side wall and an outer side wall opposite to the inner side wall, the retaining slots are disposed on the outer side wall.

4. The compression connector as claimed in claim 3, wherein the inner side wall and the outer side wall separate said two rows of passageways in a transverse direction perpendicular to the longitudinal direction.

5. The compression connector as claimed in claim 4, wherein each spring section has a first arc shape section opens orienting to the inner side wall and a second arc shape section opens orienting to the outer side wall.

6. The compression connector as claimed in claim 5, wherein the inner side wall near the first and second mating surface are provided with arc portions which slant with a tendency to the passageways, the second arc shape section has a similar shape to the arc portion.

7. The compression connector as claimed in claim 6, wherein the first housing defines two guiding posts which are retained in two guiding holes defined on the second housing, the two guiding posts are in different shape.

8. A compression connector comprising:

a first insulating housing defining a plurality of first retaining slots running through a first contacting surface thereof,

a plurality of terminals comprising retaining sections and two spring arms extending from opposite edges of the retaining sections, the retaining sections being inserted into the first retaining slots from the first contacting surface and one of said two spring arm extending to a first mating surface opposite to the first contacting surface of the first insulating housing;

a second insulating housing defining a plurality of second retaining slots running through a second contacting surface thereof, the second insulating housing being assembled with the first insulating housing and the second retaining slots being inserted with said retaining section of the terminals thereby the retaining sections of the terminals being limited in the first and second retaining slots and another spring arms extending to a second mating surface opposite to the second contacting surface wherein the retaining slots do not run through the first and second mating surfaces.

9. An electrical connector assembly comprising:

a first housing defining a coupling face and a mounting face opposite to each other in a vertical direction;

a plurality of first passageways extending through the first housing in the vertical direction, each of the first passageways being equipped with a first stopping step facing toward the coupling face;

a second housing defining a coupling surface and a mating surface opposite to each other in the vertical direction;

a plurality of second passageways extending through the second housing in the vertical direction, each of the second passageways being equipped with a second stopping step facing toward the coupling surface; and

a plurality of contacts disposed in the corresponding first passageways, respectively, under condition that each of said contacts defining opposite resilient contacting sections and opposite retention sections;

wherein

the first housing and the second housing are assembled to each other with the coupling face and the coupling surface coupled together in the vertical direction, the first passageways and the second passageways are aligned with each other in the vertical direction, respectively, the opposite resilient contacting sections extend beyond the mating face and the mating surface in the vertical direction, respectively, and the opposite retention sections are sandwiched between the first stopping step and the second stopping step in the vertical direction wherein both the mating surface and the mounting face are equipped with corresponding standoffs, respectively;

wherein said mounting face is further equipped with a mounting post while the mating surface is not;

wherein the standoffs are located in middle regions of said mounting face and the mating surface;

wherein the standoff on the first housing is located essentially outside of a corresponding end face while the standoff on the second housing is located essentially inside of a corresponding end face.

10. The electrical connector assembly as claimed in claim 9, wherein one of coupling face and the coupling surface is equipped with a guide post while the other is equipped with a guide hole for coupling with the guide post.
