A structure for connecting printed circuit boards (PCBs), electrically connecting a first PCB and a second PCB with printed circuits provided thereon, the structure includes fixing holes formed in the first PCB and the second PCB, and a harness fixed to the fixing holes at both ends to electrically connect the first PCB and the second PCB, wherein the harness includes housings arranged in a pair to be fixed to the first PCB and the second PCB and having projections to be inserted and fixed to the fixing holes, contact terminals arranged in the housings to come into contact with the printed circuits, and a cable connected to the contact terminals to electrically connect the pair of housings. ## Claims ### Claim 1 A structure for connecting printed circuit boards (PCBs), electrically connecting a first PCB and a second PCB with printed circuits provided thereon, the structure comprising: fixing portions formed in the first PCB and the second PCB; and a harness to electrically connect the first PCB and the second PCB, comprising: a pair of housings to be fixed to the fixing portions, each housing including a top housing corresponding to a top side of each of the fixing portion, a bottom housing corresponding to a bottom side of each of the fixing portion and a connecting portion to connect an end of the top housing and an end of the bottom housing; contact terminals arranged in the housings to come into contact with the printed circuits; and a cable connected to the contact terminals to electrically connect the pair of housings, wherein each of the fixing portions has an opening formed to define a combining direction of the housing, and the housing has a protruding portion formed at a position corresponding to the opening to be received in the opening when the housing is combined with the fixing portion, and wherein the protruding portion is provided at the connecting portion. ### Claim 2 (depends on 1) The structure for connecting PCBs of claim 1, wherein the structure further comprises fixing holes formed in fixing portions of the first PCB and the second PCB, and the pair of housings includes projections to be inserted and fixed to the fixing holes. ### Claim 3 (depends on 2) The structure for connecting PCBs of claim 2, wherein the opening is formed on at least one of the left and right sides of the fixing portion. ### Claim 4 (depends on 2) The structure for connecting PCBs of claim 2, wherein the contact terminals are formed in a pair to correspond to the printed circuits formed on both sides of the first PCB and the second PCB, and are formed in a linear shape or a curved shape. ### Claim 5 (depends on 2) The structure for connecting PCBs of claim 2, wherein the housing has the form to cover the fixing portion and is fixed to the fixing portion. ### Claim 6 (depends on 5) The structure for connecting PCBs of claim 5, wherein the housing further comprises a containing portion formed by the top housing, the bottom housing, and the connecting portion. ### Claim 7 (depends on 6) The structure for connecting PCBs of claim 6, wherein the number of the projections corresponds to the number of the fixing holes, and the projections comprise an upper projection formed on the bottom side of the top housing to be inserted to an upper portion of the fixing hole and a lower projection formed on the top side of the bottom housing to be inserted to a lower portion of the fixing hole. ### Claim 8 (depends on 7) The structure for connecting PCBs of claim 7, wherein the projection is formed in a rectangular shape or an oval shape, and the fixing hole is formed to have a shape corresponding to the shape of the projection. ### Claim 9 (depends on 7) The structure for connecting PCBs of claim 7, wherein the housing is combined with the fixing portion such that the fixing portion is contained in the containing portion from the perspective of the fixing portion, and if the projection is inserted to the fixing hole, the housing is fixed to prevent the housing from falling out of the fixing portion. ### Claim 10 (depends on 2) The structure for connecting PCBs of claim 2, wherein the opening comprises a first opening formed on the left side of the fixing portion and a second opening formed on the right side of the fixing portion, and the first and second openings are formed to have different length. ### Claim 11 (depends on 10) The structure for connecting PCBs of claim 10, wherein the protruding portion comprises a first protruding portion having a length corresponding to the first opening at a position corresponding to the first opening and a second protruding portion having a length corresponding to the second opening at a position corresponding to the second opening. ### Claim 12 (depends on 1) The structure for connecting PCBs of claim 1, wherein the first PCB and the second PCB are configured to be single-sided PCBs and having fixing portions, to which the housings are fixed, and the fixing holes are provided in the plural in the fixing portions. ### Claim 13 (depends on 12) The structure for connecting PCBs of claim 12, wherein the housing comprises a containing portion formed by the top housing, the bottom housing, and the connecting portion. ### Claim 14 (depends on 13) The structure for connecting PCBs of claim 13, wherein a projection is formed on the bottom side of the top housing to be inserted to the fixing hole.
