Technical Field

[0001] This invention relates to the technical field of connectors, and more particularly to a connector that can provide a tightly packed printed circuit board. Background Technology

[0002] In traditional two-piece printed circuit board connections, when connecting to another printed circuit board, a cable connection is usually used or a separate connector is used for the connection.

[0003] However, in some applications, such as automated assembly or narrow assembly spaces, when two printed circuit boards are joined together, the gap between the two printed circuit boards needs to be extremely narrow, for example, less than 4 centimeters wide, which is not suitable for connection using traditional cables.

[0004] In view of this, the present invention proposes a connector to solve the problems that traditional connectors cannot overcome. Summary of the Invention

[0005] The purpose of this invention is to provide a connector that provides a female connector to connect multiple male connectors, and enables multiple printed circuit boards connected to the multiple male connectors to achieve a dense arrangement.

[0006] The purpose of this invention is to provide a floating connection design in the female connector according to the above-described connector, so as to solve the problems of assembly errors and connector soldering errors on the printed circuit board.

[0007] The purpose of this invention is to provide a structure in which the male and female connectors are provided with corresponding springs, protrusions and stop blocks, so as to provide a stable mating (or mutual connection) when the female and male connectors are connected.

[0008] The purpose of this invention is to provide a stop, a first notch, and a second notch according to the above-mentioned connector, such that the female end slides into the stop to form interference to avoid the female end from disengaging from the opening.

[0067] Please refer to Figure 1 A perspective view of the connector according to the first embodiment of the present invention. Figure 1 In the middle, connector 10 can connect the first printed circuit board 2, the second printed circuit board 4, and the third printed circuit board 6.

[0071] Taking a rectangular shape as an example, the base 12 forms a first opening 124 and a second opening 126.

[0072] The first female end 14 is disposed at the first opening 124.

[0073] The second female end 16 is disposed at the second opening 126. The center position of the first female end 14 and the center position of the second female end 16 are at a predetermined distance.

[0074] Herein, the base 122 has a stop 1212, a first female end 14 with a first notch 1282, and a second female end 16 with a second notch 12102. The stop 1212 is disposed between the first opening 124 and the second opening 126, and the stop 1212 corresponds to the first notch 1282 and the second notch 12102 respectively. When the first female end 14 generates the first floating displacement in the first opening 124 (e.g., in the -XX direction of FIG2), the first notch 1282 slides into the stop 1212 to form interference to prevent the first female end 14 from disengaging from the first opening 124. And when the second female end 16 generates the second floating displacement in the second opening 126, the second notch 12102 slides into the stop 1212 to form interference to prevent the second female end 16 from disengaging from the second opening 126. It is worth noting that, in addition to preventing disengagement, the stop 1212 also has the function of positioning and guiding the floating direction.

2. The connector as described in claim 1, characterized in that, The seat has a stop member, the first female end has a first notch and the second female end has a second notch, the stop member is disposed between the first opening and the second opening, and the stop member corresponds to the first notch and the second notch respectively. When the first female end generates the first floating displacement in the first opening, the first notch slides into the stop member to form interference to prevent the first female end from leaving the first opening, and when the second female end generates the second floating displacement in the second opening, the second notch slides into the stop member to form interference to prevent the second female end from leaving the second opening.

3. The connector as described in claim 1, characterized in that, The base has a slot and the connector further includes a fixing member, the slot being disposed corresponding to the fixing member, one end of the fixing member being disposed on the first printed circuit board, and the slot fixing the female base to the first printed circuit board through the fixing member.

4. The connector as claimed in claim 1, characterized in that, The first male end further includes a first core, a first housing, a first insert, and a plurality of first grooves. The first housing covers the first core. The first insert extends from the first core for insertion into the first female end, and the first insert has the plurality of first grooves for providing the third terminal. The second male end further includes a second core, a second housing, a second insert, and a plurality of second grooves. The second housing covers the second core. The second insert extends from the second core for insertion into the second female end, and the second insert has the plurality of second grooves for providing the fourth terminal.

5. The connector as described in claim 4, characterized in that, The first housing further includes a first spring piece having a first protrusion and the second housing further includes a second spring piece having a second protrusion, the first spring piece being disposed in a direction extending from the first housing toward the first insert, and the second spring piece being disposed in a direction extending from the second housing toward the second insert.

6. The connector as described in claim 5, characterized in that, The inner wall of the first opening forms a first stop block to correspond to the first protrusion, and the inner wall of the second opening forms a second stop block to correspond to the second protrusion. The first stop block engages with the first protrusion, so that the first male end is limited to the first female end, and the second stop block engages with the second protrusion, so that the second male end is limited to the second female end.

7. The connector as claimed in claim 1, characterized in that, The long side of the first male end is arranged parallel to the long side of the second male end on the long side of the base.

8. The connector as claimed in claim 1, characterized in that, The first housing further includes a first spring piece with a first protrusion and the second housing further includes a second spring piece with a second protrusion, wherein the first protrusion is disposed on the side of the first spring piece and the second protrusion is disposed on the side of the second spring piece.

9. The connector as claimed in claim 8, characterized in that, The inner wall of the first opening forms a first stop block to correspond to the first protrusion, and the inner wall of the second opening forms a second stop block to correspond to the second protrusion. The first stop block engages with the first protrusion, so that the first male end is limited to the first female end, and the second stop block engages with the second protrusion, so that the second male end is limited to the second female end.

10. The connector as claimed in claim 1, characterized in that, The first male terminal is inserted into the first female terminal and the second male terminal is inserted into the second female terminal, such that the first printed circuit board is perpendicular to the second printed circuit board and the third printed circuit board.
