DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking connector for electrically connecting two printed wiring boards facing each other or in parallel to each other, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, this kind of stacking connector is composed of a pair of a male connector body and a female connector body made of resin molded by transfer molding. Further, the contact for electrical connection and the connection terminal for connection to the external wiring are punched out of a metal plate by pressing to be integrally formed. Then, a strip-shaped metal piece integrated with the contact and the connection terminal is passed through a groove or a hole of the male / female connector main body and assembled to each.

[0003]

Generally, in the case of a stacking connector, there are many types of connectors having the same outer dimensions of the connector body but different pitches of contacts and connection terminals. Conventionally, in order to manufacture a connector body of a stacking connector having different contact pitches, a connector body having grooves or holes having the same pitch as the contact pitch has been manufactured by molding. However, since the molds for molding these connector bodies are very expensive, there is a drawback that the cost per unit increases in the case of small-scale production. In addition, when this mold is not prepared, there is a problem that it takes time to manufacture the mold and it is not possible to immediately respond.

On the other hand, although contacts and connection terminals can be manufactured inexpensively by press working, special assembly equipment is required for assembling them into expensive punching dies and connector bodies, as well as assembly time and cost increase. Many factors are included.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connector body having different pitches of contacts and connection terminals by using a single mold and without preparing the contacts and connection terminals to be incorporated into the connector body in advance. It is an object of the present invention to provide a stacking connector and a manufacturing method by which a stacking connector having different pitches of the contacts and connection terminals can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIGS. 1A and 1B are a perspective view of a stacking connector according to an embodiment of the present invention and a sectional view after fitting. As shown in FIG. 1, the stacking connector is a resin-made male formed of a long base 1a on which two long side plates 5 having a bulge 7 on the outer surface are arranged in parallel and spaced apart from each other. A connector female body 2 composed of a long base 2a on which two side plates 6 are arranged and screened at an interval at which the two side plates 5 are bent and inserted inside each other; A plurality of bases 1a are arranged at equal intervals in the longitudinal direction and extend so as to extend inward from both sides of the base 1a, and extend on and adhere to the outer side surfaces including the bulges 7 of the two side plates 5. A plurality of strip-shaped first conductive films 3 solidified with paint, and a base 2 corresponding to the first conductive films 3.
and a plurality of band-shaped second conductive films 4 extending from both side ends inward and extending across the two side plates 6 and solidified with a conductive paint to be applied. .

The first conductive film 3 includes a contact 3 a, which is a conductive film formed on the bulge 7 of the side plate 5, and the base 1.
A connection terminal 3b, which is a conductive film formed on the surface a, is formed, and the connection terminals are connected by a conductive film therebetween. On the other hand, in the female connector body 2, the contact 4a inside the side plate 6 and the connection terminal 4b on the base 2a are formed of a second conductive film. As will be described later, these conductive films can be formed at arbitrary intervals by a nozzle for applying a conductive paint. Therefore, even with the male connector body 1 and the female connector body 2 molded by the same mold, several types of stacking connectors having different contact pitches can be obtained.

FIGS. 2A to 2C are cross-sectional views of the male connector main body for explaining a procedure for applying a conductive paint to the male connector main body of FIG. Next, a method of manufacturing the stacking connector will be described. First, the male and female connector main bodies are molded by using a common mold with, for example, heat-resistant vinyl chloride. Next, the male connector main body is placed on the stage of the coating apparatus. Then, FIG.
2B, the nozzle 8a is moved from the tip of the side plate 5 toward the base 1a while discharging a paste-like conductive paint such as a silver paste from the nozzle 8a. As the nozzle 8a approaches the surface of the base 1a, it is gradually rotated and tilted by the tilting mechanism, and as shown in FIGS. 2B to 2C, the base 1a is perpendicular to the surface of the base 1a. A silver paste on the top surface. Next, the male connector main body is moved by one pitch in a direction perpendicular to the plane of the paper, and the next conductive film is applied. In this manner, the male connector main body is sequentially fed to form the entire conductive film.

FIG. 3 is a sectional view of the female connector main body for explaining a procedure for applying a conductive paint to the female connector main body of FIG. On the other hand, when the conductive paint is applied to the female connector main body, as shown in FIG. 3, a nozzle 8b for applying the inside of the side plate 6 and a nozzle 8a for applying the outside of the side plate 5 are loaded in a coating device. When the application of the upper surface of the side plate 6 is completed, the nozzle is switched to the nozzle 8a by the turret head, and a conductive film is formed on the outside of the side plate 6 and the upper surface of the base 2a. Then, the female connector main body is fed by one pitch in a direction perpendicular to the paper surface, and the next conductive film is applied. In this manner, the female connector main body is sequentially fed to form the entire conductive film.

The male and female connector bodies having the conductive films formed at the desired intervals are heated by an infrared lamp and fired with silver paste, which is a conductive film, to become silver contacts and silver connection terminals. In addition, since the surface state of the conductive film after firing is slightly roughened or there is some unevenness between the conductive films, it is desirable to mechanically polish the contact portion of the fired conductive film.
In this embodiment, the conductive film serving as a contact and a connection terminal is formed one by one. However, a plurality of nozzles are arranged side by side and loaded in a coating apparatus, and a plurality of conductive films are simultaneously formed. If this happens, production efficiency will improve.

[0014]

As described above, according to the present invention, a conductive paint is applied to a male / female connector body formed by one common mold and moved across a nozzle to apply a conductive film to be a contact and a connection terminal. By forming, it is possible to eliminate the preparation of the press parts to be the contacts and the connection terminals and the incorporation into the connector main body in advance, which has the effect of reducing the cost. Since the positioning can be changed arbitrarily in the longitudinal direction of the nozzle, stacking connectors with different contact intervals can be obtained even with a connector body of the same external dimensions, so that a mold can be shared, thereby reducing costs and shortening the construction period. This has the effect.
