[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for attaching to a printed circuit board and connecting it to other parts.

0002

2. Description of the Related Art In a conventional printed circuit board connector, a first post a having a different shape and a second post b are mounted on a body c in parallel, as shown in FIG. d was soldered to the printed circuit board e, and the soldering surface of the second post b was also soldered to the printed circuit board e.

[Problems to be Solved by the Invention] However, in such a conventional example, since the shapes of the first post a and the second post b are different, two types of metal parts are required, which increases the investment amount required for manufacturing. There is also the problem that managing parts takes time and effort. Furthermore, since the parts to be connected by soldering are lined up in a row, there is a problem in that the pitch at which the first post a and the second post b cannot be attached can be narrowed.

The present invention has been made in view of the above-mentioned problems, and the objects of the present invention are to be able to standardize parts, reduce the investment amount, and reduce the effort and effort of parts management. To provide a printed circuit board connector that enables narrower pitch mounting.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the printed circuit board connector of the present invention has a plurality of first posts 1 and a plurality of second posts 2 arranged in parallel to form a first post 1 and a second post 2. The post 2 is inserted into the body 3, and the connection terminal portions 4 of the first post 1 and the second post 2 are connected to the printed circuit board 5 by soldering.
The first post 1 and the second post 2 are formed in the same shape as the post 2, and the first soldering surface 6 and the second soldering surface 7 are bent in opposite directions above and below these connecting terminal portions 4, so that the first post 1 and the second post 2 are The first post 1 is inserted into the body 3 in a line-symmetric manner, and the first soldering surface 6 of the first post 1 is soldered to the printed circuit board 5, and the second soldering surface 7 of the second post 2 is soldered to the printed circuit board 5. It is characterized by being attached.

[0006]

[Operation] First post 1 and second post 2 are the same parts
can be assembled by inserting them into the body 3 symmetrically. This allows commonization of post parts. The first post 1 can be connected to the printed circuit board 5 by soldering the first soldering surface 6 and the second post 2 by soldering the second soldering surface 7. As a result, the positions at which the first posts 1 and the second posts 2 are soldered can be shifted vertically, and the pitch between adjacent first posts 1 and the pitch between adjacent second posts 2 can be narrowed.

[0007]

[Embodiment] The first post 1 and the second post 2 are formed in the same shape. The upper part of the first post 1 and the second post 2 is a post body 9, and a buried part 10 is provided at the base of the post body 9, and a bent part 11 is provided between the post body 9 and the connection terminal part 4. A first soldering surface 6 is provided on the upper portion of the connection terminal portion 4, and a second soldering surface 7 is provided on the lower portion. The first soldering surface 6 and the second soldering surface 7 are bent in opposite directions.

[0008] The body 3 is made of synthetic resin,
As shown in FIG. 1, the first post 1 and the second post 2 are inserted and molded so that the first post 1 and the second post 2 are lined up in parallel. The first post 1 and the second post 2 are inserted so as to be line symmetrical. Connector to printed circuit board 5
, the connecting terminal portion 4 is arranged along the surface of the printed circuit board 5, the first soldering surface 6 of the first post 1 is soldered to the printed circuit board 5, and the second soldering surface of the second post 2 is soldered to the printed circuit board 5. The mounting surface 7 is soldered to the printed circuit board 5. FIG. 2(a) shows the printed portion 13 of cream solder on the printed circuit board 5 of the present invention, and since the soldering positions are vertically different between the first post 1 and the second post 2, they are provided in a staggered manner. . FIG. 2(b) shows a conventional cream solder printed portion 13, which is arranged in one row. In this way, in the present invention, since the soldering positions of the first post 1 and the second post 2 can be shifted vertically, the cream solder printed part 1
3 pitch can be narrowed, and the adjacent 1st post 1
The pitch between the two posts 2 and the pitch between the adjacent second posts 2 can be narrowed.

In the above embodiment, a male connector has been described, but the same can be applied to a socket if the shape of the connecting terminal portion is the same as in the above embodiment.

0010

[Effect of the invention] As described above, the present invention provides the first post and the second post.
Since the posts are made the same shape and the first and second posts are inserted into the body in a line-symmetrical manner, the first and second posts can be made of the same metal part, making it easier to This allows for common use, reduces the investment amount, and saves the effort of parts management.Moreover, the first and second soldering surfaces are provided above and below the connection terminals of the first and second posts. The first soldering surface of the first post is soldered to the printed circuit board, and the second soldering surface of the second post is soldered to the printed circuit board. The soldering position can be changed up and down, the soldering interval can be narrowed, and the pitch of the first post and the second post can be narrowed.
