Connector and board connecting assembly comprising the same
The present invention provides a connector and a board connecting assembly. The connector according to the present invention includes a connection pin partially inserted into a board to transmit a high-frequency signal, and a dielectric body having a first opening into which the connection pin is inserted, wherein the connection pin includes a central portion, which is disposed in the first opening of the dielectric body, and a first connection portion extending upward from the central portion and protruding upward from the dielectric body, and a diameter of the central portion is greater than that of the first connection portion.
1. A connector, comprising:
a connection pin partially inserted into a board to transmit a high-frequency signal;
a dielectric body including a first opening into which the connection pin is inserted;
a ground body including a second opening into which the dielectric body is inserted and including a first surface and a second surface, which face away from each other, having a flat shape; and
a first supporter which protrudes from an inner peripheral surface of the ground body toward a center of the second opening and supports a lower surface of the dielectric body,
wherein the connection pin includes a central portion, which is disposed in the first opening of the dielectric body, and a first connection portion extending upward from the central portion and protruding upward from the dielectric body,
wherein a diameter of the central portion is greater than that of the first connection portion,
wherein the connection pin further includes a contact portion which includes a cross-sectional area that is different from that of the first opening and is supported on athe lower surface of the dielectric body,
wherein the contact portion includes at least a portion inserted into an accommodation space defined by the first supporter and the dielectric body, and is spaced apart from the first supporter,
wherein a lower surface of the first supporter is disposed to be coplanar with a lower surface of the contact portion, and
wherein a height of the first supporter is same as a height of the contact portion.
2. The connector of claim 1 , wherein the connection pin further includes a second connection portion which extends downward from the central portion and protrudes downward from the dielectric body.
3. The connector of claim 1 , further comprising a first protrusion disposed on an outer peripheral surface of the central portion and supported on an inner peripheral surface of the dielectric body.
4. The connector of claim 1 , wherein the dielectric body includes a plurality of dielectric holes which pass vertically through the dielectric body and include an open upper surface and an open lower surface or a plurality of dielectric grooves of which at least one of an upper surface and a lower surface is open.
5. The connector of claim 1 , further comprising:
a second protrusion disposed on one of the inner peripheral surface of the ground body or an outer peripheral surface of the dielectric body; and
a second groove formed in the other of the inner peripheral surface of the ground body or the outer peripheral surface of the dielectric body and coupled to the second protrusion.
6. The connector of claim 1 , further comprising a second protrusion disposed on the inner peripheral surface of the ground body and coupled to an outer peripheral surface of the dielectric body in a press-fit manner.
7. The connector of claim 1 , further comprising:
a second protrusion disposed on the inner peripheral surface of the ground body; and
a second stepped portion which is disposed on an outer peripheral surface of the dielectric body and on which the second protrusion is seated.
8. The connector of claim 1 , further comprising:
a first protrusion disposed on any one of an inner peripheral surface of the dielectric body or an outer peripheral surface of the connection pin; and
a second protrusion disposed on any one of the inner peripheral surface of the ground body or the outer peripheral surface of the dielectric body,
wherein the first protrusion and the second protrusion are disposed at different levels.
9. The connector of claim 1 , further comprising a joint member which is inserted into the ground body and includes a lower surface supporting the dielectric body and the ground body.
10. The connector of claim 9 , further comprising at least one mounting portion which is formed on the inner peripheral surface of the ground body and on which a portion of the joint member is seated.
11. The connector of claim 10 , further comprising at least one trench which is formed in an outer circumferential surface of the dielectric body and in which another portion of the joint member is seated.
12. The connector of claim 9 , wherein the joint member is provided as a plurality of joint members of which at least one pair face each other.
13. The connector of claim 1 , wherein the dielectric body is formed by coupling a plurality of separate dielectric pieces to the connection pin.
14. The connector of claim 13 , wherein the connection pin further includes:
a second supporter which is vertically spaced apart from the contact portion, includes a cross-sectional area that is different from that of the first opening, and is supported on an upper surface of the dielectric body.
15. The connector of claim 14 , wherein the dielectric body further includes an accommodation groove for forming a space into which the second supporter is inserted.
