Bridge assembly
The present invention relates to a bridge assembly. The bridge assembly according to an exemplary embodiment of the present invention includes: a bridge configured to include a first leg fixed to an upper surface of a printed circuit board, a second leg fixed to the printed circuit board to be spaced apart from the first leg, and an elastic part connecting between the first leg and the second leg and applying an elastic force to any one of the first and second legs; and a cover configured to be positioned at an upper side of the bridge to receive the elastic part.
1. A bridge assembly, comprising:
a bridge including
a first leg fixed to a first surface of a printed circuit board,
a second leg fixed to the first surface of printed circuit board to be spaced apart from the first leg, and
an elastic part connecting between the first leg and the second leg and applying an elastic force to any one of the first and second legs; and
a cover positioned at an upper side of the bridge to receive the elastic part, including
an upper part positioned over the elastic part,
a first extending part extending from a first side of the upper part to be toward a first surface of the first leg, and
a second extending part extending from a second side of the upper part to be toward a first surface of the second leg,
wherein a second surface of the first leg and a second surface of the second leg that are positioned opposite to the first surface of the first leg and the first surface of the second leg, respectively, are fixed to the first surface of the printed circuit board, and
wherein at least one of the first and second extending parts is positioned to be spaced apart from the corresponding first surface of the first leg or the corresponding first surface of the second leg.
2. The bridge assembly of claim 1 , wherein the first leg and the second leg are fixed to the first surface of printed circuit board by a soldered joint.
3. The bridge assembly of claim 1 , wherein the first leg and the second leg are soldered to the printed circuit board using soldering materials having different melting temperatures.
4. The bridge assembly of claim 1 , wherein the elastic part extends while being bent at least two times from a rear end portion of the first leg to be integrally connected to a front end portion of the second leg.
5. The bridge assembly of claim 1 , wherein the elastic part includes
a first bending part extending while being bent from a rear end portion of the first leg,
a second bending part formed to be inclined from an end portion of the first bending part,
a third bending part extending from an end portion of the second bending part,
a fourth bending part formed to be inclined from the third bending part to the second leg, and
a fifth bending part extending while being bent from an end portion of the fourth bending part to be connected to the front end portion of the second leg.
6. The bridge assembly of claim 1 , wherein a front end portion of the first leg and a rear end portion of the second leg each protrude to outer sides of the first extending part and the second extending part.
7. The bridge assembly of claim 1 , wherein a front end portion of the first leg protrudes to an outer side of the first extending part and a rear end portion of the second leg is positioned at an inner side of the second extending part.
8. The bridge assembly of claim 1 , wherein a front end portion of the first leg and a rear end portion of the second leg are each positioned at inner sides of the first extending part and the second extending part.
9. The bridge assembly of claim 1 , wherein the cover has a semi-spherical shape having an opening part at the first surface of any one of the first leg and the second leg.
10. The bridge assembly of claim 1 , wherein the cover is integrally formed in a housing in which the printed circuit board is received.
