Abstract

This electrical connection socket for relaying exchange of electrical signals between a first electrical component and a second electrical component, is provided with: a metallic casing which has a communication hole for communication between the upper surface and lower surface of the metallic casing, to the lower surface side of which the first electrical component is attached, and to the upper surface of which the second electrical component is attached; a signal pin which is disposed in the communication hole so as to be separated from the inner wall surface of the communication hole, one end of which is electrically connected to a terminal of the first electrical component, and the other end of which is electrically connected to a terminal of the second electrical component; an annular first holding member which is, in the upper region of the communication hole, press-fitted in the communication hole; and an annular second holding member which is, in the lower region of the communication hole, press-fitted to the outer circumferential surface of the signal pin, wherein the signal pin is fixed in the communication hole so as to be held by the metallic casing from above and from below via the first and second holding members.

First claim

1 . An electrical connection socket for relaying transmission and reception of an electrical signal between a first electrical component and a second electrical component, the electrical connection socket comprising:
a metal housing including a communication hole for communicating between an upper surface of the metal housing and a lower surface of the metal housing, the metal housing being disposed such that the first electrical component is disposed at the lower surface, and that the second electrical component is disposed at the upper surface; a signal pin disposed apart from an inner wall surface of the communication hole in the communication hole such that one end of signal pin is electrically connected to a terminal of the first electrical component and that another end of the signal pin is electrically connected a terminal of the second electrical component; a first holding member having an annular shape and press-fitted and fixed in the communication hole in an upper region in the communication hole; and a second holding member having an annular shape press-fitted and fixed to an outer peripheral surface of the signal pin in a lower region in the communication hole, wherein the signal pin is fixed so as to be sandwiched by the metal housing from an upper side and a lower side through the first holding member and the second holding member in the communication hole.

2 . The electrical connection socket according to claim 1 , wherein the signal pin includes:
a pin barrel fixed by the first holding member and the second holding member in the communication hole; and a first plunger and a second plunger coupled to the pin barrel at an upper end portion and a lower end portion of the pin barrel, respectively, such that the first plunger and the second plunger are slidable in a vertical direction.

3 . The electrical connection socket according to claim 1 , wherein an upper end surface of the first holding member is flush with the upper surface of the metal housing.

4 . The electrical connection socket according to claim 1 , wherein each of the first holding member and the second holding member is composed of an insulating elastic member.

5 . The electrical connection socket according to claim 1 , wherein a characteristic impedance of the signal path formed by the signal pin is lower than a predetermined characteristic impedance serving as a reference in a first region and a second region, and is higher than the predetermined characteristic impedance in a third region and a fourth region adjacent to the first region and the second region, the first region and the second region being regions where the signal pin is held by the first holding member and the second holding member.

6 . The electrical connection socket according to claim 1 ,
wherein the first electrical component is a circuit board; and wherein the second electrical component is an IC package.
