Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a connector used to connect printed circuit boards.

``Prior Art'' As shown in FIG. 6, connectors used to connect printed circuit boards each have a board connecting part 1a on one end that is inserted into a through hole of one printed board and soldered. The board connecting part 1b is inserted into the through hole of the other printed circuit board and soldered on the other end side, and the intermediate part 1c between the board connecting part 1a and the board connecting part 1b is a long flat plate. A plurality of conductor pieces 1 are fixed, with the starting end of the board connecting portion 1a being embedded in one long insulator 2a, and the starting end of the board connecting portion 1b being embedded in the other long insulating member 2b. The intermediate portions 1 of the conductor pieces 1 are fixed to each other and arranged in the respective width directions, and prevent adjacent conductor pieces 1 from coming into contact at their intermediate portions 1c and causing a short circuit.
Similarly to c, a plurality of long flat partition pieces 2c are connected at positions between adjacent conductor pieces 1, with one end connected to one insulator 2a and the other end connected to the other insulator 2b. A structure in which the insulators 2a and 2b are connected and formed integrally is considered, and the application was published as Japanese Patent Publication No. 35073/1983.

``Problems to be Solved by the Invention'' However, as is clear from FIG. 6, the conventional connector described above has a structure in which the whole is formed into a flat plate shape, and the partition piece 2c integrally connects the insulators 2a and 2b. Therefore, the printed circuit board to be connected is initially a split board consisting of the main board and sub-board, and after connecting the main board and sub-board with a connector while they are in this integrated state, the sub-board is connected. When splitting and arranging in a predetermined positional relationship such as perpendicular or parallel to the main board, first cut the board connection part 1 of the conductor piece 1.
a into the main board, then bend the middle part 1c of the conductor piece 1 and the partition piece 2c against the spring force of both, and insert the board connection part 1b of the conductor piece 1 into the sub-board, and then connect the board. The parts 1a and 1b must be soldered to the main board and the sub-board, and two steps are required to attach the connector to the split board.
Also, since a strong force is required to bend the partition piece 2c, there is a drawback that the workability of mounting onto the split board is poor.

Further, as is clear from FIG. 6, since the intermediate portion 1c and the partition piece 2c of the conductor piece 1 are structured to be able to move freely in either direction in their respective thickness directions, the conductor piece 1 Board connection part 1a
and 1b to the main board and the sub board, and then split the sub board and rotate it in a predetermined direction with respect to the main board and place it in a predetermined positional relationship with the main board. Depending on the positional relationship and the mounting position of the connector on the main board and sub-board, etc., the intermediate part 1c of the conductor piece 1 may be separated from the adjacent intermediate part 1c and the partition piece 2c between the two.
conductor patterns formed or mounted on the main board or sub-board that must not be in contact, such that the intermediate parts 1c of adjacent conductor pieces 1 move in opposite directions to each other and the intermediate parts 1c of the conductor pieces 1 move in opposite directions There is a risk of contact with parts.

Therefore, this invention improves the workability of mounting onto printed circuit boards in connectors used to connect printed circuit boards to each other, reduces the manufacturing cost of printed circuit devices, and also reduces the number of conductor strips in the connector. This prevents adjacent ones from touching and causing a short circuit, and the conductor pieces from coming into contact with conductor patterns or parts formed or mounted on a printed circuit board that should not be contacted.

"Means for Solving the Problems" The connector of this invention is composed of a pair of insulators, a plurality of conductor pieces, and one or more insulating pieces.

The pair of insulators are formed separately from each other, and each has a shape consisting of an elongated base and a plurality of partition walls arranged in the longitudinal direction of the base and formed integrally with the base.

Each of the plurality of conductor pieces is formed into a long plate shape, and one end of each is placed between adjacent partition walls of one insulator, and the board connection portion at the tip is connected to the side where the partition wall is at the base. Embed it in the base and fix it to one insulator, facing the opposite side.
The other end of each insulator is embedded in the base between adjacent partition walls of the other insulator, with the board connection part at the tip facing the side opposite to the side with the partition wall of the base. fixed to the body, each intermediate portion being bent between a pair of insulators into a shape having a central top and hem portions on both sides thereof;
Arrange in the direction in which the partition walls of each insulator are arranged.

One or more insulating strips thereby connect the plurality of conductor strips at the top.

"Operation" The connector of this invention configured as described above has one end fixed to one insulator of each conductor piece and the other end fixed to the other insulator on the same plane. Since the printed circuit board to be connected is made up of a main board and a sub board, and is initially formed as a single unit as a split board, if you connect the main board and sub board while they are still a unit, there will be no problem. without requiring special strength,
The board connecting portion on one end side and the board connecting portion on the other end side of each conductor piece can be inserted into the main board and the sub board at the same time, improving the workability of mounting on the split board.

Further, one end and the other end of each conductor piece are fixed to one and the other insulators at a position between adjacent partition walls of the one and the other insulators, and the middle part of each conductor piece is fixed to the pair of insulators. The conductor is bent between the insulators into a shape that has a central top and skirts on both sides, and the tops of each conductor piece are connected by an insulating piece, so as mentioned above, the connector can be split into a board. After soldering the board connection part on one end of each conductor piece and the board connection part on the other end to the main board and sub board, split the sub board and rotate it in the specified direction relative to the main board. When placed in a predetermined positional relationship with respect to the main board, the middle part of each conductor piece may be part or all of the bottom part, or a part of the top part near the bottom part, depending on the rotation angle of the sub board with respect to the main board. The conductor pieces fit between corresponding adjacent ones of a pair of insulator partition walls and always move together in a predetermined direction with respect to one end and the other end, and the middle part of the conductor piece is formed on the main board or sub board or There is no possibility of contact with a mounted conductor pattern or component that should not come into contact, and there is no possibility of adjacent conductor pieces coming into contact at their intermediate portions and causing a short circuit.
