面実装用のコネクタに関する。
The present invention relates to a connector mounted on a printed wiring board, and more particularly to a surface mounting connector that can be easily mounted on a printed wiring board.

うになつてきた。 In recent years, due to the miniaturization of electronic devices, the patterns on printed wiring boards have become finer and denser, and surface mount methods are often used to mount components, in which they are soldered directly to the surface pattern of the printed circuit board without using lead wires. It's starting to feel like this.
このため、プリント板に搭載されるコネクタに
関しても、表面実装に適した構造が要求されてい
る。 For this reason, connectors mounted on printed boards are also required to have a structure suitable for surface mounting.

FIG. 2 is a perspective view showing a conventional surface-mount connector. The figure shows the connector viewed from the printed board mounting side, in which a plurality of contacts 1 are embedded in two rows on an insulator 2. The contact 1 has, for example, a pin-shaped male contact portion 11 at one end that is inserted and connected to the contact of the mating connector.
However, the other end is formed with a terminal section 12 that is surface-connected to a pad 31 on the surface of the printed board 3 to be mounted, by reflow soldering, etc., and two rows of terminal sections 12 are formed on both sides of the printed board 3. It is planted in the insulator 2 so as to be in contact with it. The insulator 2 is integrally formed by molding with mounting ears 21 having screw holes 24 at both ends for screwing and fixing to the printed board, and guide grooves 22 into which the edge surface of the printed board is inserted and positioned. There is.

２１に固定されるようになつていた。 Then, the edge of the printed board 3 is inserted between the two rows of terminal portions 12 of the contacts, and is fitted and fixed into the guide groove 22 of the insulator 2, and if necessary, the insulator is fixed by the mounting screw 4. It was designed to be fixed to the mounting ear part 21 of the.

By the way, when a large number of wiring patterns are to be processed on a printed board, a multilayer printed board with multiple conductor layers is used, and the thickness of the printed board varies depending on the number of layers.

け耳２１の位置が設定されている。 The above-mentioned conventional connector is intended for a printed board of one type of thickness, as shown by a in the side sectional view showing the relationship between the printed board and the connector in FIG. The position and width of the guide groove 22 of the insulator 2 and the position of the mounting lug 21 are set so that the center of the terminal portion 22 of the two rows of contacts is located at the center of the terminal portion 22 of the two rows of contacts.

る。 Therefore, when mounted on printed boards with different thicknesses, the center of the board thickness of the printed board 3 and the row center of the contact terminal portions 12 do not match, as shown in b and c in FIG. 2 of the contacting terminals
This causes a problem that the pressing force is unbalanced between the rows, and the subsequent reflow soldering is not uniform. In other words, the terminals on the lower side of the printed board contact each other with an appropriate pressing force, but on the upper side, if the printed board is thick like b, the pushing force is too strong and the terminal gets deformed, and if it is thin like c, the terminals will not touch the printed board. There is a gap between.

プになるという問題点もあつた。 In addition, if the board thickness is different, it becomes impossible to fit into the guide groove 22, and the adhesion force between the printed board and the connector is insufficient. Therefore, it is necessary to hold the printed board by screwing it with the mounting ears 21 of the insulator. There is. In this case, mounting screws are required, which not only increases the number of parts, but also causes problems in that the screw tightening work is complicated and costs increase.

The above-mentioned conventional problem is that the connector consists of a plurality of contacts connected to pads on the edge of a printed wiring board and an insulator in which the contacts are embedded in two rows. A plurality of mounting grooves whose widths are successively narrower and whose depths are successively deeper are formed on the opposing surfaces of the pair of mounting ears that protrude from both ends to face each other, so that the center line of the mounting grooves is aligned along the protruding direction. This problem is solved by the connector of the present invention, which is characterized in that it is provided in a stepped manner so as to be located in the same plane as the center line between two rows of contacts.

となり、バランスのよい接続が可能である。
By setting the widths of the plurality of mounting grooves to a predetermined value, the same connector can be mounted on many types of printed boards having different thicknesses to match the widths of the respective grooves. In this case, regardless of the thickness, the center of the thickness of the printed board is located at the center of the two rows of contacts, so the terminals of the contacts are in contact with the same pressing force on both sides of the printed board, and the terminals and the printed board are in contact with each other with the same pressing force. The reflow soldering conditions for the pads on the board are the same on both sides, allowing for well-balanced connections.

減を図ることができる。 Furthermore, the opposing mounting ears sandwich the edges of both sides of the inserted printed circuit board in the thickness direction and width direction over a certain length using the mounting grooves, so that the connector and the printed board can be held together. It is possible to secure the fixation, reduce the need for mounting screws, etc., and reduce costs.

つている。 The insulator 1 is molded and has an opening 23 on the front (back side in the figure) that fits with a mating connector.
is formed, into which the male contact portion 11 of the contact 1 protrudes, and at both ends of the rear surface, a pair of mounting ears 21 that protrude oppositely are formed, forming a substantially U-shape when viewed from above. . The opposing surfaces of the pair of mounting ears 21 have a plurality of mounting grooves 21a, 21b, which have a width equal to the thickness of the printed board to be mounted, and the narrower the width, the deeper the depth from the opposing surface.
21c is formed along the protruding direction of the mounting ear portion 21, and each mounting groove 21a, 21b, 21c
are sequentially formed concentrically at the bottom of each mounting groove so that the center line in the width direction is located in the same plane as the center line between the two rows of contacts 11, and the wall surface is stepped.

成すればよい。 The connector having the above configuration can be mounted on three types of printed boards 3a, 3b, and 3c having different thicknesses. That is, the mounting grooves 21a, 21b, 21b
Since the widths of the connectors correspond to the thicknesses ta, tb, and tc of the printed board, the width of the connector mounting portion of each printed board can be shaped to match the depth of the respective groove.
