ない。 In communication devices and the like, a large number of sheet boards (printed boards) having various functions are housed in a rack. Such a sheet board is connected to a backboard (printed board) of the racking device through a connector having a large number of terminals. A printed circuit pattern is connected to each land on the sheet board and the back board, which is provided with a land for attaching a plug-side connector and a jack-side connector, that is, a connector land corresponding to the connector terminal. Such connector lands are bored on a reference grid that serves as a reference for forming a circuit pattern on a printed board. The spacing of this reference grid is 2.50mm series and 2.54mm series.
types of printed boards are commonly used. Therefore, there are two types of connector terminal pitches, 2.50 mm and 2.54 mm, depending on the printed circuit board, and jacks and plugs of the same pitch are used as a pair. When connecting a sheet board and a back board that have different reference grid grid spacings, the conventional method is to convert the sheet board pattern so that the pitch of the connector land for attaching the connector on the seat board is formed to match the back board's reference grid. They were connected by a connector. That is, a buffer land is provided at the pitch of the reference grid of the circuit pattern on the sheet board, and a connector land of a different pitch from the land is formed adjacent to this buffer land, and the corresponding buffer land and connector land are connected in the pattern. However, the pitch conversion method using such a pattern requires a buffer land part in addition to the connector land part on the sheet board, so it is not only subject to space constraints.
Since patterns are formed on the sheet board based on two types of reference grids, it is not possible to automate a pattern check on the entire surface of the sheet board using an automatic wiring tester, which is carried out by contacting test terminals with land positions corresponding to the reference grids.

成している。 The present invention has been made in view of the above points, and an object of the present invention is to provide a pitch conversion connector that can connect printed boards with different reference grids without converting the reference grid depending on the pattern of the printed board. Therefore, in the present invention, a plurality of printed board joining lead terminals are protruded in parallel from one side of the connector main body, and connector connecting terminals integrated with each of the lead terminals are provided in parallel on the other side. A pitch conversion connector is formed in which the arrangement pitch of the lead terminals and the arrangement pitch of the connector connection terminals are different.

にプリント配線設計の自動化も容易になる。 As shown in FIG. 1, the pitch conversion connector according to the present invention has a plurality of printed board joining lead terminals 2 protruding in parallel from one side of the connector body 4,
On the other side, each of the lead terminals 2 and the integrated connector connecting terminal 3 (in this case, a plug terminal) are arranged in parallel, and a recess 4 into which a jack side connector (not shown) is fitted is provided.
a, and the arrangement pitch P2 of the lead terminals 2 and the arrangement pitch P1 of the connector connection terminals 3 are formed to be different from each other. Such a pitch conversion connector is attached to the sheet plate 7 whose reference grid pitch is P2 .
Connector lands 5 for inserting the lead terminals 2 of the connector are formed on this sheet plate 7 at intervals of pitch P2, and each connector land 5 is connected to a wiring pattern 6 connected to a circuit pattern (not shown). As shown in FIG. 2, the sheet plate 7 to which the plug-side connector having the connector connection terminal of the pitch P1 is attached is attached to the jack-side connector 8 of the back board 9 whose reference grid pitch is P1 . The pitch of both the connector connection terminal (jack terminal) of this jack side connector 8 and the lead terminal for connection to the backboard is P1 . In this way, by changing the pitch of the connection terminals of the connector without changing the reference grid of the wiring pattern of the sheet board 7, sheet boards having different reference grid intervals can be connected to the backboard. Therefore, the entire surface of the sheet board 7 can be effectively used as a circuit pattern, and since the reference grid is unified to one type, pattern checking can be automated, and printed wiring design can also be automated easily.

なピツチ変換コネクタを形成する。 When manufacturing the pitch conversion connector as described above, first, as shown in FIG . , the pitch of the connector connection terminals is set to P1 , and the connector connection terminals are formed by punching a single metal plate into a shape connected via the lead frame 1. At this time, the terminal piece 10
The amount of deviation between the lead terminal 2 and the connector connecting terminal 3 increases as the deviation distance increases from the terminal piece with the deviation amount O, that is, the straight reference terminal piece (the leftmost terminal piece in the figure). The amount of deviation of the th terminal piece is n·(P 2 −P 1 ). The position of the reference terminal piece is not limited to the left end, but may be at the right end or the center of the group of terminal pieces to be manufactured. Next, as shown in Fig. 4, on the integrated terminal piece group punched in this way,
The connector body 4 is molded. Subsequently, the lead frame 1 connecting the terminal pieces is cut and removed, and the lead terminals 2 are bent to form a pitch conversion connector as shown in FIG.
