Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector for electrically connecting two printed circuit boards.

[Conventional technology]

In the conventional connector of this kind, as shown in FIGS. 8 to 11, a plug connector 1 is attached to a movable housing 2, a base housing 3 separated from the movable housing 2, and both housings 2, 3. The strip-shaped male terminal portion 4A of the electric contact 4 is fixed and protrudes horizontally from the front surface of the flat plate portion 2A of the movable housing 2. , the male terminal portion 4A
A terminal portion 4B of a predetermined length that hangs straight from the rear end is inserted into and fixed to the base housing 3, and the tip of the terminal portion 4B protruding from the bottom surface is inserted into the first board 5 and soldered. .

On the other hand, the socket connector 6 which can be freely fitted to the plug connector 1 has a swing flex type female terminal part 8A which sandwiches the male terminal part 4A of the electrical contact 4 in the housing 7 for electrical connection. An electrical contact 8 with a housing 7 is housed therein.
The tip of the terminal portion 8B of the electric contact 8 protruding from the bottom surface is soldered to the second substrate 9.

Therefore, when electrically connecting the plug connector 1 and the socket connector 6, as shown in FIG. 4B is bent and its male terminal portion 4A is inserted into the female terminal portion 8A of the socket connector 6, and both printed circuit boards 5 and 9 are electrically connected.

[Problem that the invention attempts to solve]

As mentioned above, the conventional plug connector 1 is composed of two pieces, the movable housing 2 and the base housing 3, which makes it difficult to work and maintain, and is expensive in terms of cost. The plug connector 1 cannot connect boards arranged vertically in parallel, and its range of use is limited.

The movable housing 2 also has a socket connector 6.
Since positioning is not achieved with respect to both boards 5,
9, it is difficult to fit the movable housing 2 into the socket connector 6, and the male terminal portion 4A of the electrical contact 4 and the electrical contact 8 female terminal part 8
There are disadvantages such as contact with A becomes uncertain.

Furthermore, since the movable housing 2 and the base housing 3 are only connected by a substantially straight electrical contact 4, the movable housing 2 swings and the automatic insertion machine inserts the base housing into the first board 5. There were various problems such as not being able to insert 3.

[Means for solving problems]

The present invention was developed to solve the above-mentioned conventional problems, and by forming a fitting guidance and positioning mechanism on the movable housing and the socket connector, the two can be easily fitted. The purpose of the present invention is to provide a device that can be connected reliably and that can be automatically inserted into a printed circuit board by integrating the movable housing and the base housing with a disconnectable connection part. The gist is that a movable housing that accommodates the contact side of an electric contact and a base housing that accommodates the terminal side of the contact and is mounted on a board are connected by a disconnectable connection, and The movable housing of the first connector or the second A guide rib is provided on either side of the connector housing,
There is provided a printed circuit board connector characterized in that the other side is provided with a guide groove that can be freely fitted with the guide rib.

F easily absorbs these by expanding, contracting or twisting, and this curved portion 4F absorbs minute vibrations propagating to both contact parts 4A and 17A in the connected state, thereby preventing wear between both contact parts. can be done.

Note that when the movable housing 2 is in an upright state and the male terminal portion 4A of the electric contact 4 is fixed in a vertical state, the second It becomes possible to electrically connect to the connector 13.

[Other Examples]

In the above embodiment, the first connector 1 was used as a plug connector and the second connector 13 was used as a socket connector, but as shown in FIG.
The first connector 1 may be a socket connector, and the second connector 13 may be a plug connector. That is, the housing 4 has a female electric contact 17, a guide groove 16, etc. on the upper part of the movable housing 2.
A male electrical contact 4 is provided in the second connector 13.
Of course, even if guide ribs 6 and the like are arranged, the same effects as in the above embodiment can be obtained.

[Effect of idea]

As described above, the printed circuit board connector according to the present invention is capable of separating the movable housing that houses the contact side of the electric contact and the base housing that houses the contact side of the contact and mounts it on the board. It consists of a first connector that is connected at a connecting part and that connects both housings so that they can be bent by the electrical contact, and a second connector that is connected to the first connector and mounted on another board. Since the configuration has a guide rib protruding from either the movable housing of the first connector or the housing of the second connector, and a guide groove that can freely fit into the guide rib on the other side, the number of parts is reduced, and workability and maintenance are improved. In addition to improving the performance, both connectors can be mated accurately in the specified state even if there is a misalignment in the front-back, left-right direction, or a step in the mounting position of the first and second connectors on each printed circuit board. can do.

Therefore, it is possible to make a reliable electrical connection, and it can also be used for both vertical and horizontal connections. Furthermore, by integrating the movable housing and the base housing with a disconnectable connecting part, the movable housing and the base housing are in an upright state, allowing automatic insertion into the printed circuit board, and the first connector is connected to the edge of the printed circuit board. Since it can be mounted at a location away from the electrical contact, there are various advantages such as being able to solder the terminal portion of the electrical contact with an automatic soldering device without using a waste board as in the conventional method.
