DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector in which a large number of terminals are pressed into a board at high density, a method of manufacturing the connector, and a connector manufacturing apparatus.

2. Description of the Related Art In various devices in the field of electronics and communications, a circuit board composed of a printed wiring board is mounted with many circuit functions, and a number of these circuit boards are plugged into a casing unit such as a shelf in parallel. Thus, various device functions are configured.

[0003] As described above, the circuit board into which the plug-in is inserted is arranged and mounted on the rear side of the inside of the housing in such a manner that connectors are respectively mounted on BWBs (Back Wiring Boards) which are printed wiring boards for connection. The connector is inserted and connected to a connector provided on the back side of the substrate.

The present invention is suitable for application to a connector mounted on such a BWB. In such a connector, the terminals are arranged at a reference pitch interval. In recent years, with the increase in the number of terminals, the pitch interval has been reduced without simply increasing the size of the connector, and The size is also becoming finer and higher density.

FIG. 28 shows a typical example of a connector applied to a BWB, in which FIG. 1 (a) is a sectional side view of a main part and FIG. 2 (b) is a front view of the connector. That is, a large number of circuit boards 1 made of a multi-layer printed wiring board, and in the case of this connector, terminals having a total of 189 pins have terminal rows 2 each having 32 pins and terminal rows 3 each having 31 pins in columns. The frame 5 made of synthetic resin, which is a connector housing serving as a protection and a guide, is alternately press-fitted laterally to the rows. The member indicated by reference numeral 6 is a fixing plate.

The vertical spacing (pitch) of each of the terminal rows 2 and 3 of the connector is 2.54 mm, and the horizontal spacing (pitch) of the adjacent rows is 1.27 mm. As can be seen, they are arranged in a staggered arrangement shifted by 1/2 pitch in the vertical direction. Therefore,
The side view interval between the terminal rows 2 and 3 is 1.27 mm. That is, it is an inch-type high-density connector having a pitch of 1.27 mm in all vertical and horizontal directions.

[0007]

2. Description of the Related Art A conventional method of manufacturing and assembling the above-mentioned connector will be described with reference to a sectional side view of a main part of FIG. 29. The press-fitting shoulders 8 of the terminals 7 are provided at a predetermined pitch interval of the fixing plate 6. Each of the holes is press-fitted and arranged as shown in the figure. In this state, the press-fitting portion 11 is pushed into the terminal insertion hole 9 of the circuit board 1 by pressing the shoulder 8 for press-fitting from the near side in the figure by a press-fitting device not shown. Next, the terminal insertion hole 12 is also pushed into the terminal 7 and the frame 5 is attached in a press-fit state.

Since a conductor layer is formed in the terminal insertion hole 9 of the circuit board 1 by through-hole plating and is connected to a wiring pattern, the press-fitted terminals 7 are respectively brought into press-contact with predetermined circuits. Connection is made.

According to the conventional connector manufacturing and assembling method shown in the sectional side view of the main part shown in FIG. 30, a terminal 5 is provided in a frame 5 provided with a terminal insertion hole into which a press-fitting shoulder 8 is inserted at a predetermined pitch. The press-fitting shoulders 8 of FIG. 7 are arranged by press-fitting, and the press-fitting portions 11 projecting downward are collectively inserted into the terminal insertion holes 9 of the circuit board 1 by a press-fitting device (not shown). The circuit board 1 in a state where the press-fitting portion 11 is pushed in by being pressed from the side is indicated by a two-dot chain line.

According to the conventional connector manufacturing and assembling method shown in the sectional side view of the main part shown in FIG. 31, terminals 7 are aligned and held at predetermined pitch intervals by a press-fitting device (not shown), and terminal insertion holes 9 of circuit board 1 are formed. At the same time, the press-fitting shoulder 8 is pressed from the near side in the figure to press-fit the press-fitting portion 11, and the terminal insertion hole 12 of the frame 5 is pressed into the terminal 7 to be mounted in a press-fit state.

The terminal 7 is shown in a partially enlarged plan view of FIG. 32. A portion other than the terminal 7 is punched and removed by a continuous press working on a strip-shaped metal plate long in the lateral direction in the drawing, and a predetermined pitch is removed. The terminal row 15 is formed in a long strip shape exactly at the interval.

In order to maintain an interval between the terminals 7 on the left and right sides (up and down in the figure) so that the terminals 7 are not separated,
The carrier 16 is formed and left continuous. Pilot holes 17 serving as a reference are formed in the carrier 16 at an accurate pitch for setting a position at the time of processing.

At the time of press-fitting, the portion indicated by the two-dot chain line or the solid portion 18
After the press-fitting or during the press-fitting step, the remaining carrier 16 is also removed.

As is apparent from the drawing, the press-fitting shoulder portion 8 is set to have a required width, and a gap 19 is formed between adjacent portions. For example, if the terminal interval is 2.54 mm, the width of the press-fitting shoulder 8 is 1.54 mm. Therefore, the width of the gap 19 is set to 1.0 mm.

The material of the terminal 7 is selected from a copper alloy having good electric conductivity and appropriate elasticity and mechanical strength. For example, the terminal 7 is made of a phosphor bronze plate. Au plating is applied to secure the property.
The press-fit portion 11 is formed in a ship bottom shape in cross section, and the circuit board 1 is formed.
The terminal connection hole 9 is press-fitted into the terminal insertion hole 9 and the contact connection is made by elastic deformation of the hull-like portion.

[0016]

As described above, according to the conventional connector manufacturing method, the terminals 7 shown in FIG. 32 are formed as a terminal row 15 by, for example, continuous pressing at a pitch of 2.54 mm. Therefore, in order to form the connector shown in FIG. 27, it is necessary to preliminarily process two types of sets cut into a 32-pin terminal row and a 31-pin terminal row, and a predetermined number of Must be cut into a row of terminals.

Next, as shown in FIG. 29 or FIG. 30, it is necessary to press-fit the fixing plate 6 or the frame 5 for positioning. For this purpose, the fixing plate 6 is required, or a specially shaped insertion hole for press-fitting the press-fitting shoulder 8 into the frame 5 is required.

Connectors with different pitch intervals, for example millimeters or narrower pitches of 2.5 mm, 2 mm
mm, 1.27 mm, etc., it is necessary to make a new press mold or press-fitting device or prepare it.

In the case of the terminal row 15 as shown in FIG. 32, many portions are punched and discarded.
With a 4 mm pitch, that percentage can range from 60 to 70 percent.

In FIGS. 29, 30, and 31, the interval 19 between the terminals 7 is enlarged for easy understanding, but is actually narrow as shown in FIG. When the pitch becomes finer, the gap 19 becomes narrower. Since punching of this portion does not guarantee the strength of the press die, the punching speed must be reduced.

To reduce the width of the press-fitting shoulder 8, it is necessary to reduce the width of the press-fitting device 21 with respect to the hole 22 of the press-fitting device 21, as shown in FIG. In addition, there is also a problem that the contact area of the press-fitting shoulder portion 8 is reduced, so that a sufficient pressing force cannot be applied.

Referring to FIG. 33, FIG. 33 (a) is a cross-sectional view of a main part, and FIG. 33 (b) is an enlarged view of FIG. In a state where the terminals 7 are aligned and held by the fixing plate 6 or the like, all the terminals 7 are inserted into the respective terminal insertion holes 22 opened in the press-fitting device 21. As shown in FIG. , Given by a circular hole determined by the diagonal of the terminal.

This is because a square hole is preferable, but it is difficult to form a large number of square holes with a high degree of positional accuracy, so that a circular hole is easily formed. Therefore, the press-fitting pressing force acting on the press-fitting shoulder 8 is within the range between the outside of the circular hole 22 in FIG. (B) and the press-fitting shoulder 8 indicated by a dotted line.

In view of the various problems described above, the present invention solves the conventional problem of press-fitting a large number of terminals into a substrate at high density, and a connector and a method of manufacturing the connector.
