BACKGROUND OF THE INVENTION The present invention is used in a state where a large number are radially taped to a mount via connecting pins and sequentially transferred by an automatic insertion machine, and then separated from the mount and automatically inserted into a printed circuit board. The present invention relates to a printed circuit board connector.

[0002]

2. Description of the Related Art In a connector of this type, a large number of connectors are radially taped and delivered from a component maker to a board assembling maker, and the board assembling maker mounts the connector on the printed board using an automatic insertion machine or the like. It has become common these days. FIG. 7 shows a conventional radially-taped right-angle board connector 11.
This is an example. In the board connector 11, the distal end of the connecting pin 13 a extending continuously to the vertical portion of the right-angled L-shaped fitting pin 13 inserted into the housing 12 is attached to the mount 5 via the adhesive strip 6. Radial taping.

[0003] Each of the radially taped board connectors 11 is intermittently transported with the feed hole 7 engaged with the pawl of the feed mechanism of the automatic insertion machine, and swings 90 degrees around the fulcrum 15 as shown in FIG. The sheet is pulled out of the backing sheet 5 by the rotating transfer chuck 16 and separated. Next, 90 around the fulcrum 16
Anvil 18 by insertion chuck 17 that rotates
Is transferred to above the insertion position where it is installed, and the insertion chuck 17 is vertically lowered to be automatically inserted into the printed circuit board 19. In this case, a guide chuck 20 is interposed between the insertion chuck 17 and the printed circuit board 9, and the connection pin 13 a is accurately guided by the guide chuck 20 into a mounting hole of the printed circuit board 9. The connecting pin 13a having the mounting hole inserted therein is connected to a pair of left and right cutters 21 and 21 interposed between the printed circuit board 9 and the anvil 18.
The connector 11 is cut into a predetermined length, and is bent at a bent portion 18 a provided on the upper surface of the anvil 18, so that the connector 11 is locked and held on the printed circuit board 9.

[0004]

As described above, in the case of the right-angle type board connector 11 in which the tip of the connecting pin 13a vertically extending from the right-angled L-shaped fitting pin 13 is radially taped. 7. Each openable and closable gripping claw 1 attached to the tip of the insertion chuck 17 as shown in FIG.
The front and rear surfaces (left and right in the drawing) of the board connector 11 are sandwiched between 7a and 17b, and the vertically provided connecting pins 13a are automatically inserted into the insertion holes of the printed circuit board 9. At this time, in order to accurately position the connecting pin 13a with respect to the insertion hole of the printed circuit board 9, the connecting pin 13a is protruded from the center of the front and rear width dimension L of the board connector 11 so as to be evenly approached from the front and rear. The gripping claws 17a and 17b hold the front and rear surfaces of the board connector 11 and connect the connecting pins 13a from the center.
Need to be erected. This conventional board connector 1
In FIG. 1, since the housing 12 is formed by adding extra meat to make the front-rear width L substantially equal to the front-rear width L of a general right-angle type board connector, the front-rear width L becomes twice or more, There are problems that the effective utilization rate of the printed circuit board is reduced, and that the cost increases due to the use of useless materials.

In order to solve this problem, the present applicant has proposed a board connector capable of reducing the front-rear width L in Japanese Utility Model Laid-Open No. 4-1122491. As shown in FIG. 8, the board connector 31 is
Is a connector fitting portion 33 connected to a mating connector.
a, a housing engaging portion 33b obtained by bending a base of the fitting portion 33a downward along the back surface of the housing 32;
A folded portion 33c obtained by bending the engaging portion 33b inward.
And a board insertion portion 33d in which the tip of the folded portion 33c is bent downward, and a partition plate 22a protrudes from the rear surface of the housing 2. Board connector 3 of this configuration
1, the board insertion portion 33d of the pin 33 is connected to the housing 32.
Of the housing 32 in the front-rear width direction, and the dimension L of the housing 32 in the front-rear width direction can be reduced.

However, in the case of the board connector 31, the fitting pins 33 must be bent in a complicated manner in a hook shape, and there is a problem that bending of the fitting pins 33 in the manufacturing process is not easy. . Further, since the fitting pins 33 bent in a hook shape need to be inserted horizontally from the rear side of the housing 32 to assemble the board connector 31, the assembly becomes complicated, and a series of manufacturing processes of the connector 31 are automated. There is a problem that the assembling process is complicated when performing by a line.

Therefore, the present invention has been proposed to solve such problems of the conventional technology, and makes it possible to easily work the fitting pin and to easily attach the fitting pin to the housing. By doing so, an object of the present invention is to provide a board connector capable of improving productivity.

[0008]

According to the present invention to achieve this object, a board insertion portion of a fitting pin mounted on a housing of a right angle type board connector is suspended from just below a center of a front-rear width dimension of the housing. The connecting pin is connected to the board insertion portion of the fitting pin, the connecting pin is adhered to the mount, and radial taping is performed.
In the board connector, the front and rear surfaces of the housing are evenly held by an insertion chuck of an automatic insertion machine, pulled out of the backing paper, and the connection pins are automatically inserted into the insertion holes of the printed circuit board by inserting the connection pins into the guides. The housing is composed of at least left and right side plates, a rear wall extending to the center in the front-rear direction between the side plates, and a bottom plate formed in front of the rear wall. A connector fitting portion to be fitted to the connector extends horizontally toward the front opening, and a housing planting portion obtained by bending a base of the connector fitting portion downward at right angles forms an upper surface of the rear wall. It penetrates downward and is planted in the rear wall, and the housing planting portion extends linearly further downward to form a substrate insertion portion.
