Abstract

In one example, the present invention relates to a signal contact unit with ameliorated passive inter-modulation distortion (PIMD) characteristics, and a board mating connector including the same. The signal contact unit includes a housing which has a housing insertion hole of which one side is open; a contact portion which has a contact portion insertion hole of which the other side is open; and a signal spring which is inserted between the one side of the housing insertion hole and the other side of the contact portion insertion hole, wherein one side of the housing is partially inserted into the contact portion insertion hole, and in a state in which the signal spring is compressed, an inner side of the contact portion comes into contact with an outer side of the housing so that the housing and the contact portion are electrically connected.

First claim

We claim:

1. A board mating connector which includes a signal contact unit with ameliorated passive inter-modulation distortion (PIMD) characteristics, the board mating connector comprising:
a signal contact unit;
a ground contact unit which has a ground hollow portion, wherein the signal contact unit is inserted into the ground hollow portion; and
a dielectric unit which is disposed between the signal contact unit and the ground contact unit,
wherein the signal contact unit includes:
a housing which has a housing insertion hole of which one side is open;
a contact portion which has a contact portion insertion hole of which the other side is open, wherein:
the contact portion includes a contact portion protrusion which protrudes from an inner wall of the other end of the contact portion, and
two or more contact portion slits which are elongated to one side of the contact portion from the other end thereof along a circumference of the contact portion; and

a signal spring which is inserted between the one side of the housing insertion hole and the other side of the contact portion insertion hole,
wherein one side of the housing is partially inserted into the contact portion insertion hole, and in a state in which the signal spring is compressed, an inner side of the contact portion comes into contact with an outer side of the housing so that the housing and the contact portion are electrically connected.

2. The board mating connector of claim 1 , wherein, in a state in which the signal spring is restored, the contact portion protrusion is inserted into a housing groove formed in a ring shape along a circumference of the housing.

3. The board mating connector of claim 1 , wherein the ground contact unit includes:
a first ground portion which has a first ground hollow portion; and
a second ground portion of which the other side is partially inserted into the first ground hollow portion and which has a second ground hollow portion.

4. The board mating connector of claim 3 , further comprising a ground spring which is disposed between an inner side of the first ground portion and an outer side of the second ground portion,
wherein, when the second ground portion is moved in a direction of the first ground portion, the ground spring is compressed by the second ground portion, and the compressed ground spring is restored so that the second ground portion is moved in a direction opposite to the direction of the first ground portion.

5. The board mating connector of claim 4 , wherein:
the first ground portion includes a tapered portion which is formed on an inner wall of the first ground portion so as to have an inclined shape such that an inner diameter thereof is gradually decreased toward the other side thereof; and
the second ground portion includes a second ground protrusion which protrudes outward from the other end of the second ground portion and two or more second ground slits which are elongated to one side of the second ground portion from the other end thereof along a circumference of the second ground portion,
wherein, when the second ground portion is moved in the direction of the first ground portion, an outer diameter of the second ground protrusion is compressed by the tapered portion, and the compressed outer diameter of the second ground protrusion is restored in a direction in which an inner diameter of the tapered portion is increased so that the second ground portion is moved in the direction opposite to the direction of the first ground portion.

6. The board mating connector of claim 3 , wherein:
the first ground portion includes a tapered portion of which an inner diameter is gradually decreased toward the other side thereof on an inner wall of the first ground portion; and
the second ground portion includes a second ground protrusion which protrudes outward from the other end of the second ground portion and two or more second ground slits which are elongated to one side of the second ground portion from the other end thereof along a circumference of the second ground portion,
wherein, when the second ground portion is moved in a direction of the first ground portion, an outer diameter of the second ground protrusion is compressed by the tapered portion, and the compressed outer diameter of the second ground protrusion is restored in a direction in which an inner diameter of the tapered portion is increased so that the second ground portion is moved in a direction opposite to the direction of the first ground portion.

7. The board mating connector of claim 3 , wherein:
the dielectric unit includes a first dielectric portion which is disposed between the first ground portion and the signal contact unit; and
a second dielectric portion which is disposed between the second ground portion and the signal contact unit,
wherein a second dielectric hollow portion having a diameter greater than that of the signal contact unit is formed in the second dielectric portion so that the second dielectric portion is in surface contact with the second ground portion and is not in surface contact with the signal contact unit.

8. The board mating connector of claim 3 , wherein:
the first ground portion includes a thread formed on a circumference of the other side of the first ground portion; and
a tightening portion formed to have three or more surfaces on a circumference of one side of the first ground portion.

9. A board mating connector which includes a signal contact unit with ameliorated passive inter-modulation distortion (PIMD) characteristics, the board mating connector comprising:
a signal contact unit;
a ground contact unit which has a ground hollow portion, wherein the signal contact unit is inserted into the ground hollow portion; and
a dielectric unit which is disposed between the signal contact unit and the ground contact unit,
wherein the signal contact unit includes:
a housing which has a housing insertion hole of which one side is open, wherein:
the housing includes a housing protrusion which protrudes from an inner wall of one end of the housing, and
two or more housing slits which are elongated from one end of the housing to the other side thereof along a circumference of the housing;

a contact portion of which the other side is partially inserted into the housing insertion hole; and
a signal spring which is inserted between the one side of the housing insertion hole and the other side of the contact portion,
wherein, in a state in which the signal spring is compressed, an outer side of the contact portion comes into contact with an inner side of the housing so that the housing and the contact portion are electrically connected.

10. The board mating connector of claim 9 , wherein, in a state in which the signal spring is restored, the housing protrusion is inserted into a contact portion groove formed in a ring shape along a circumference of the contact portion.

11. The board mating connector of claim 9 , wherein the ground contact unit includes:
a first ground portion which has a first ground hollow portion; and
a second ground portion of which the other side is partially inserted into the first ground hollow portion and which has a second ground hollow portion.

12. The board mating connector of claim 11 , further comprising a ground spring which is disposed between an inner side of the first ground portion and an outer side of the second ground portion,
wherein, when the second ground portion is moved in a direction of the first ground portion, the ground spring is compressed by the second ground portion, and the compressed ground spring is restored so that the second ground portion is moved in a direction op
