Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board mounting connector having means for aligning terminals on the side of a circuit board (hereinafter simply referred to as "board") in alignment with holes for connecting terminals of the board. The present invention relates to a board mounting connector in which each board-side terminal of the connector is completely matched with a connection terminal hole of the board to facilitate mounting on the board and improve productivity.

In the field of electronic equipment in recent years, the size of connectors mounted on a board has been reduced in order to meet the demand for miniaturization of devices, but the progress of electronic technology has led to high-density mounting and the number of signals to be exchanged. Therefore, the number of terminals as a connector tends to increase more and more, and the miniaturization of the terminals incorporated therein is progressing along with the above demand for miniaturization.

However, as a result, the terminals before mounting on the board are likely to be deformed or bent, so that the board mounting is provided with means for aligning the terminal area to be connected to the board with the connection terminal holes of the board. Connectors have been put to practical use.

2. Description of the Related Art FIG. 4 is a diagram for explaining a configuration example of a connector provided with a conventional terminal aligning means, (4-1) shows the configuration, and (4-2) shows a state during assembly as a connector. Again (4-3)
Shows the completed state of each connector.

FIG. 5 is a diagram showing an example of the structure of a connector provided with another terminal aligning means. In each of the drawings, a case where a right angle type jack connector in which jack terminals are arranged in a matrix of two rows is mounted on a substrate will be described as an example.

In FIG. 4 (4-1), the connector 1 is formed with tongue-shaped jack contacts 11a and 12a each having the same length at one end and curved in opposite directions, and has a length following the respective contacts 11a and 12a. After being bent at right angles through different fixing parts of the two, the other end having different lengths is formed on the terminals 11b, 12b for connecting the board, each of which is a plurality of two types of jacks made of a metal plate for spring such as phosphor bronze. The terminals 11 and 12 and the terminals 11 and 12 are located at the same positions from the contact tips of the respective fixing parts so that the contact areas and the board connecting terminal areas are located in parallel in a matrix of two rows. The formed bulges 11c, 12c are configured by an insulator 13 that can be planted by press-fitting fixation.

Then, the jack terminals 11 and 12 implanted in the insulator 13 have the common connecting member 1 in the state before implantation.
1'and 12 'are connected to each other at the board connection terminal side in a comb-like shape with an equal pitch.

It should be noted that the bulge 11d, the bulge 11d,
12d are formed respectively. On the other hand, the above terminals 11, 12
Insulators 13 having square holes 13a having a width capable of fixing each of the jack contact side bulges 11c and 12c in the terminal fixing wall 13b are formed in a matrix of two rows.
The peripheral wall 13c higher than the contact length around each jack contact arrangement area when the terminals 11 and 12 are fixed by
The terminal is inserted into each of the positions corresponding to the square holes 13a in the board mounting wall 13d which is formed to have an L shape over the entire length from the side of the terminal for connecting the board on the rear surface of the fixed wall 13b. A terminal guide groove 13e having a possible width is formed with the outer side of the board mounting wall as an opening.

The terminal guide groove 13e in this case is

Terminal side bulge 11d, 12 for board connection when press-fitted and fixed with c
Positionally corresponds to d.

The board mounting wall 13d is provided with mounting holes 13f on the board at both longitudinal end portions thereof. Therefore, first, the jack terminals connected to the connecting member 11 'as shown by the arrow a ₁ are provided in one row of the square holes 13a formed in line in the insulator 13.
When 11 is press-fitted, the board connection terminal side bulge 11d is simultaneously press-fitted into the terminal guide groove 13e, so that the jack terminal 11 is fixed to the insulator 13 by the bulge 11c and the bulge 11d.

Then, similarly, an arrow a _{2 is formed} on the other row side of the square hole 13a.
As described above, the jack terminal 12 connected to the connecting member 12 'is press-fitted to obtain the state shown in (4-2). Therefore, the conventional connector 1 shown in (4-3) can be constructed by cutting and removing only the connecting members 11 'and 12' with a tool not shown.

The connector 1 can be constructed at low cost because it can be made up of one insulator 13 and two kinds of terminals 11 and 12, but one terminal guide groove 13e has two kinds of terminals.
Since 11 and 12 are fixed by respective bulges 11d and 12d, the board connecting terminals 11b and 12b of the terminals 11 and 12 may incline independently in the direction of the groove 13e, that is, in the direction of b in the drawing. Sometimes it has to be fixed.

FIG. 5 showing another example of the structure of the connector is put into practical use in order to avoid the disadvantage,
In the drawing, since the connector described in FIG. 4 is taken as an example, the same target members and parts are denoted by the same symbols.

In FIG. 5, (5-1) is a diagram for explaining the configuration, and (5-2) is a diagram showing a state when the connector is completed. In (5-1) of the figure, the connector 2 has the same shape as the jack terminals 11 and 12 of FIG. 4, but only the bulges 11d and 12d on the board connection terminal side described in FIG. 4 are not formed. 21,22, an insulator 23 for implanting the plurality of jack terminals 21,22 in the same manner as in FIG. 4, and the jack terminals 2 described above.

It consists of 4 and.

The insulator 23 in this case is the insulator of FIG.
Although it has substantially the same shape and configuration as that of 13, it is formed by replacing the board mounting wall 13d including the terminal guide groove 13e of the insulator 13 with the board mounting piece 23a only in the mounting hole 13f forming region. However, the terminal guide groove 13e described in FIG. 4 is not formed.

Further, the terminal aligning plate 24 made of an insulating material which can be fixed between the board mounting pieces 23a by press-fitting between the board mounting pieces 23a is a terminal for connecting each board of the jack terminals 21 and 22.
Through holes 24a, through which the terminals 21a, 22a can be positioned and penetrated, are formed at respective positions corresponding to 21a, 22a by providing chamfered portions.

Therefore, as in FIG. 4, the jack terminals 21 and 22 connected to a connecting member (not shown) are connected to the square hole 13a of the insulator 23.
The connector body 2'shown in (5-1) can be obtained by press-fitting and fixing each row and then cutting off each connecting member.

Then, the above-mentioned terminal aligning plate 24 is press-fitted and fixed between the two board mounting pieces 23a of the connector body 2'as indicated by an arrow c to fix the required connector 2 in (5-2). It can be configured as shown.

[0019] Such the connector 2, the terminal alignment plate even when bent two-dimensionally as terminals 22a ₁ shown in board connecting terminals 21a of the terminals 21, 22, 22a, for example, (5-1)
Since it can be corrected to the regular position at 24, it is possible to facilitate the board mounting work in the next process.

[0020]

However, in the connector 1 described with reference to FIG. 4, the jack terminals 11 and 12 for connecting the respective boards are provided.
Since 11d and 12d easily fall in the direction of the terminal guide groove 13e, there is a problem that it is not possible to expect improvement in productivity because correction man-hours are required when mounting on the board, and the connector explained in FIG. In No. 2, since the terminal aligning plate 24 is required in addition to the insulator 23, there is a problem that it is not possible to meet the customer's request for cost reduction.
