[Industrial applications]

 The present invention is a connector for a printed circuit board that is used by being sequentially transferred by an automatic insertion machine in a state where a large number of them are radially taped to a mounting board through a connecting pin, and then separated from the mounting board and automatically inserted into a printed circuit board. It is about.

[Prior art]

 In this type of printed circuit board connector, a large number of connectors are radially taped and delivered from a component maker to a board assembly maker, and the board assembly maker is nowadays mounted on the printed circuit board using an automatic insertion machine or the like. It is becoming popular. FIG. 7 shows an example of a conventional radial taping right-angled board connector 11. In this board connector 11, the tip of the connecting pin 13 a extending continuously from the vertical portion of the rectangular L-shaped fitting pin 13 inserted into the housing 12 has the adhesive piece 6 on the mount 5. It is connected through and is radial taping.

The radial taping of each board connector 11 is intermittently transferred by engaging the feed hole 7 with the pawl of the feed mechanism of the automatic insertion machine, and swings 90 degrees about the fulcrum 15 as shown in FIG. It is pulled out from the mount 5 by the rotating transfer chuck 16 and separated. Next, after the umbili 18 is transferred to a position above the insertion position where the ambile 18 is installed by the insertion chuck 17 which swings about the fulcrum 16 by 90 degrees, the insertion chuck 17 is vertically lowered and automatically inserted into the printed circuit board 19. It In this case, the guide chuck 20 is interposed between the insertion chuck 17 and the printed board 9, and the connecting pin 13a is accurately guided by the guide chuck 20 to the mounting hole of the printed board 9. Further, the connecting pin 13a inserted through the mounting hole is cut to a predetermined length by a pair of left and right cutters 21 and 21 interposed between the printed board 9 and the anvil 18, and is provided on the upper surface of the anvil 18. It is bent at the bent portion 18a, and the connector 11 is retained by the printed circuit board 9 in a locked state.

[Problems to be solved by the device]

 As described above, in the case of the right angle type board connector 11 in which the tip of the connecting pin 13a hung from the right-angled L-shaped fitting pin 13 is radially taped, as shown in FIG. The front and rear surfaces (left and right in the drawing) of the board connector 11 are clamped by openable and closable holding claws 17a and 17b attached to the tip of the printed wiring board 9, and the vertically connected connecting pin 13a is inserted into the insertion hole of the printed board 9. Automatically insert into. At this time, in order to accurately position the connecting pin 13a with respect to the insertion hole of the printed board 9, the connecting pin 13a is projected from the center of the front-back width dimension L of the board connector 11 and is evenly arranged from the front and back. It is necessary that the approaching gripping claws 17a and 17b sandwich the front and rear surfaces of the board connector 11 so that the connecting pin 13a is vertically provided from the central portion. In this conventional board connector 11, since the housing 12 is formed by adding an extra thickness in order to make it approximately equal to the front-rear width dimension L of a general right angle board connector, it is more than doubled. However, there is a problem in that the effective width of the printed circuit board is lowered and the cost is increased due to useless material.

In order to solve this problem, the applicant of the present application has previously proposed, in Japanese Utility Model Laid-Open No. 4-112491, a board connector that can reduce the front-rear width dimension L. In this board connector 31, as shown in FIG. 8, the fitting pin 33 has a connector fitting portion 33a connected to the mating connector, and the base portion of the fitting portion 33a is moved downward along the rear surface of the housing 32. The housing 2 is provided with a bent housing engaging portion 33b, a folded-back portion 33c obtained by bending the engaging portion 33b inward, and a board insertion portion 33d obtained by bending the tip of the folded-back portion 33c downward. A partition plate 22a is projectingly provided on the part. In the board connector 31 of this configuration, the board insertion portion 33d of the pin 33 can be projected downward from the central portion (1/2 · L) 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. Can be made smaller.

However, in the case of the above-mentioned board connector 31, the fitting pin 33 has to be complicatedly bent and formed in a hook shape, and there is a problem that the bending process of the fitting pin 33 in the manufacturing process is not easy. . Further, since the fitting pin 33 bent into a hook shape needs 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 steps of the connector 31 is performed. When using an automated line, there is a problem that the assembly process becomes complicated.

Therefore, the present invention has been proposed in order to solve the problems of the conventional technique, and facilitates the processing of the fitting pin and the assembling of the fitting pin into the housing. The purpose is to provide a connector for substrates that can improve productivity by making it possible.

[0008]

[Means for Solving the Problems]

 According to the present invention, which achieves this object, the board insertion portion of the fitting pin mounted on the housing of the right-angle board connector is hung vertically from just below the center of the front-rear width dimension of the housing. The connecting pins are connected to the board insertion part and the connecting pins are bonded to the mount for radial taping.The front and rear surfaces of the housing are evenly clamped by the insertion chuck of the automatic insertion machine and pulled out from the mount. In a board connector in which the board insertion part of the mating pin is automatically inserted into the insertion hole of the printed board using the connecting pin as a guide, the housing is passed at least to the left and right side plates and to the center part in the front-rear direction between these side plates. It is composed of a rear wall and a bottom plate formed in front of this rear wall. A housing planting portion that extends horizontally toward the rear wall is formed by bending the base of the connector fitting portion downward at a right angle and penetrating downwardly on the upper surface of the rear wall. A base plate insertion portion is formed by linearly extending the housing planting portion further downward.

[Effect of device]

 As is apparent from the embodiments described above, in the connector for a printed circuit board according to the present invention, the mating pin mounted on the housing only needs to be bent at a right angle in the connector mating portion, which is different from the conventional one. Machining of the mating pin is greatly simplified because there is no need to bend it intricately. Also, the fitting pin is inserted into the housing by vertically inserting it into the rear wall that is passed through the center part in the front-rear direction between the left and right side plates, so that the board connector assembly process is simplified. The productivity of the connector can be significantly increased.
