Abstract

The present invention relates to a board connection assembly being characterized by comprising: a board connection pin for transmitting a signal; a dielectric portion having a first insertion hole into which the board connection pin is inserted; a housing having a trench into which a part of the dielectric portion is inserted and a second insertion hole into which the board connection pin is inserted; and a ground contact portion disposed between the housing and the dielectric portion to contact a ground electrode, wherein the ground contact portion has one side inserted into the trench so as to contact one surface of the trench, and the other side formed to be grounded with the ground electrode, and the height of the housing is configured to be smaller than the width of the housing.

First claim

The invention claimed is:

1 . A board connection connector, comprising:
a board connection pin configured to transmit a signal; a dielectric part comprising a first insertion hole into which the board connection pin is inserted; a housing comprising a trench into which the dielectric part is partially inserted, a stepped portion disposed around the periphery of the trench, a protrusion disposed to protrude inside the trench, and a second insertion hole provided in the protrusion into which the board connection pin is inserted; and a ground contact part disposed between the housing and the dielectric part to be in contact with a ground electrode, wherein: the ground contact part is formed such that a portion thereof is inserted into the trench and the other portion thereof is grounded to the ground electrode, a portion of the ground contact part is inserted inside the stepped portion, the dielectric part includes:
a dielectric body comprising the first insertion hole; and
a dielectric protrusion protruding from an edge portion of the dielectric body in a longitudinal direction,
the dielectric protrusion is inserted into the trench such that a lower surface of the dielectric body contacts an upper surface of the protrusion, and a height of the housing is smaller than a width of the housing.

2 . The board connection connector of claim 1 , wherein a plurality of legs extending downward from the housing along a side surface of the trench are formed in the housing.

3 . The board connection connector of claim 2 , wherein the leg is integrated with the housing through an insert injection process.

4 . The board connection connector of claim 2 , wherein the leg includes:
a first portion extending along the side surface of the trench; a second portion extending in a direction perpendicular to a longitudinal direction of the housing; and a third portion extending downward from the housing.

5 . The board connection connector of claim 4 , wherein the ground contact part includes:
a ground insertion portion inserted into the trench; a ground elastic portion which extends from the ground insertion portion in a longitudinal direction and is formed by a plurality of slits recessed along a circumference of the ground insertion portion; and a ground portion which extends from the ground elastic portion in the longitudinal direction and of which one side is grounded to the ground electrode.

6 . The board connection connector of claim 5 , wherein the ground insertion portion is inserted into the trench such that an outer surface thereof overlaps one surface of the first portion of the leg.

7 . The board connection connector of claim 5 , wherein the ground elastic portion has a curved shape to be inserted inside the stepped portion.

8 . The board connection connector of claim 5 , wherein the ground portion has a curved shape such that one side thereof is grounded to the ground electrode.

9 . The board connection connector of claim 5 , wherein:
the ground insertion portion includes an inner surface in contact with an outer surface of the dielectric part and a fixing protrusion protruding from at least a portion of the inner surface; and the dielectric protrusion includes a fixing groove which is formed to face the fixing protrusion in a portion of the outer surface and to which the fixing protrusion is coupled.

10 . The board connection connector of claim 5 , wherein the ground elastic portion includes:
a first elastic portion extending outward from the ground contact part in a direction perpendicular to the longitudinal direction of the ground contact part from the ground insertion portion; a second elastic portion extending from the first elastic portion in the longitudinal direction of the ground contact part; and a third elastic portion extending inward from the ground contact part in the direction perpendicular to the longitudinal direction of the ground contact part from the second elastic portion.

11 . The board connection connector of claim 5 , wherein a length of the ground insertion portion is smaller than a length of the ground elastic portion and the ground portion.

12 . A board connection assembly, comprising:
an adapter connector including an adapter connection pin configured to transmit a signal, a dielectric body into which the adapter connection pin is inserted, and a ground body into which the dielectric body is inserted; and a board connection connector including a board connection pin configured to transmit the signal, a dielectric part comprising a first insertion hole into which the board connection pin is inserted, a housing into which the board connection pin and the dielectric part are inserted, and a ground contact part which is disposed between the dielectric part and the housing and is in contact with a lower surface of the ground body, wherein: the housing includes a trench into which a portion of the dielectric part is inserted, a stepped portion disposed around the periphery of the trench, a protrusion disposed to protrude inside the trench, and a second insertion hole provided in the protrusion into which the board connection pin is inserted, the ground contact part is formed such that a portion thereof is inserted into the trench and the other portion thereof is grounded to the ground body, a portion of the ground contact part is inserted inside the stepped portion, the dielectric part includes a dielectric body comprising the first insertion hole and a dielectric protrusion protruding from an edge portion of the dielectric body in a longitudinal direction, the dielectric protrusion is inserted into the trench such that a lower surface of the dielectric body contacts an upper surface of the protrusion.

13 . The board connection assembly of claim 12 , wherein:
the adapter connector includes the adapter connection pin partially inserted into a first board, the dielectric body having a first opening into which the adapter connection pin is inserted, and the ground body which comprises a second opening into which the dielectric body is inserted and of which a first surface and a second surface opposite to each other have a flat shape; the adapter connection pin includes a central portion disposed in the first opening of the dielectric body and a first connection portion extending upward from the central portion and protruding from the dielectric body; and a diameter of the central portion is greater than a diameter of the first connection portion.

14 . The board connection assembly of claim 13 , wherein the adapter connection pin further includes a contact portion which comprises a cross-sectional area different from that of the first opening and is supported on a lower surface of the dielectric body.

15 . The board connection assembly of claim 14 , wherein
a height of the housing is smaller than a width of the housing.

16 . The board connection assembly of claim 12 , wherein the adapter connector further includes a plurality of leads extending downward from the ground body in a longitudinal direction of the ground body.
