[0012]

[Problems to be solved by the invention]

However, this conventional composite connector 1
10, the jack contacts 114, 115,
It is necessary to provide each of the legs 116a, 115a, and 116a integrally with the printed wiring board for electrical connection. For this reason, the yield of the material is low, and an extra pressing process for forming the same is required. Was needed.

The conductive pads 120 and 121 and the jack contacts 114, 115 and 116 can
The legs are insulated from each other and insulated housing 11
2, the insulating housing 11
2 cannot be miniaturized, which has been an obstacle to miniaturization of the entire communication device to which the composite connector is attached.

Further, these legs 120b, 121b,
Although it is necessary to project 114a, 115a, and 116a so as to be flush with the printed wiring board, it becomes difficult to align all of the feet on the same plane as the number of legs increases, and The leg portions of the wire floated from the conductive pattern, causing a poor solder connection.

Further, for example, there are conductive patterns common to each other, such as the conductive patterns of the legs 120b and 114a connected to the positive electrode of the power plug and the conductive patterns of the legs 121b and 11a connected to the negative electrode. Nevertheless, in the above-described composite connector 110, each leg is soldered to the conductive pattern of the printed wiring board. Therefore, it is necessary to electrically connect these common conductive patterns without contacting other conductive patterns, and between the common conductive patterns.
There has been a problem that a jumper wire is used or a conductive pattern becomes long, and the layout of the conductive pattern on the printed wiring board becomes complicated.

The jack contacts 114, 11
Reference numerals 5 and 116 are fixed to the insulating housing 112 by press-fitting, locking, and the like. When the power plug is inserted and removed, a force in the insertion and removal direction is repeatedly applied to the plug contact portion, and the legs 114a, 115a, and 116a are removed. Movement of the solder connection portion may cause solder peeling from the conductive pattern.

The present invention has been made in view of such conventional problems, and is electrically connected to both a power plug and a power contact of a butt contact type.
It is an object of the present invention to provide a composite connector that can be reduced in size without increasing the number of legs connected to a conductive pattern of a printed wiring board by soldering.

It is another object of the present invention to provide a composite connector which prevents solder connection failure of a surface-mounted composite connector and simplifies the design of a conductive pattern.

Further, even if the power plug is repeatedly inserted and removed,
An object of the present invention is to provide a composite connector that does not cause solder peeling with a conductive pattern.

[0021]

To achieve the above object, a composite connector according to a first aspect of the present invention includes an insulating housing having a plug insertion hole into which a power plug is inserted, and a plug insertion hole supported by the insulating housing. A plug contact portion facing the inside contacts a power supply plug inserted into the plug insertion hole, and a contact contact portion supported by the insulating housing and exposed along the outer surface of the insulating housing corresponds to a power supply contact of the charging case. A slit is formed in the jack contact in a composite connector that has a conductive pad that makes abutting contact and electrically connects either the power plug or the power contact of the charging case to the conductive pattern of the printed wiring board to which the insulating housing is attached. The connected part is formed integrally with the plug contact part, and the conductive pad is The protruding part and the leg part for solder connection with the conductive pattern of the printed wiring board are formed integrally with the contact contact part, the plate-shaped protruding part is pressed into the slit, and the jack contact and the conductive pad are electrically connected. And

By simply press-fitting the plate-shaped protrusion into the slit of the connecting portion, the work of attaching the jack contact and the conductive pad to the respective insulating housings can be electrically connected to each other. Since the conductive pad has legs formed to be connected to the conductive pattern of the printed wiring board by soldering, the jack contact that is in contact with the same power supply electrode as the conductive pad is connected to the conductive pad of the printed wiring board through the conductive pad legs. Can be electrically connected to the pattern.

Therefore, in the composite connector electrically connected to both the power plug and the abutting contact type power contact, it is not necessary to provide the leg of the jack contact and the conductive pattern to which the leg is connected by soldering. And the conductive pattern of the printed wiring board can be simplified.

Further, even if the jack contact moves due to the insertion / removal of the power plug, the conductive pad connected to the jack contact by press-fitting the plate-like projection into the slit includes:
The movement is not transmitted, and the solder connection portion between the conductive pad and the conductive pattern does not peel off.

Further, in the composite connector according to the second aspect, a middle portion of the contact contact portion made of a strip-shaped metal plate is folded to form a plate-like projection projecting in a direction perpendicular to the contact contact portion, thereby forming a U-shape. A plate-shaped projection is press-fitted into a slit cut out from the U-shaped top of the folded connection portion so as to intersect with the connection portion.

When a plate-shaped projection formed by folding a band-shaped metal plate is pressed into a slit of a connecting portion folded in a U-shape so as to cross the connecting portion, at least four different positions are obtained.
The conductive pad and the connecting portion of the jack contact come into contact with each other, and even if they are displaced from each other, one of the portions is electrically connected, and the reliability of the connection can be secured.

Further, the composite connector according to the third aspect is characterized in that the leg portion of the conductive pad is protruded from the insulating housing in a cantilever manner, and is connected by soldering to the conductive pattern of the opposing printed wiring board.

Since the legs which are surface-mounted on the printed wiring board and which are to be solder-connected to the conductive patterns protrude only from the conductive pads, they can be easily aligned on the surface of the printed wiring board, and defective solder connections can be prevented.

Further, in the composite connector according to the present invention, the plug contact portions of the plurality of jack contacts supported by the insulating housing are insulated from each other so as to face the plug insertion holes, and the respective connecting portions are insulated from each other. A plurality of conductive pads supported by the insulating housing are electrically connected.

Since the plurality of jack contacts are insulated from each other and supported by the insulating housing, they can be brought into contact with the corresponding terminals of the multipolar power plug.

[0063]

As described above, according to the first aspect of the present invention, in the composite connector electrically connected to both the power plug and the contact power supply contact, the jack contact is connected to the conductive pattern of the printed wiring board. Since there is no leg for connection with the material, the yield of the material is good and the molding is easy.

Further, since there is no leg portion of the jack contact, the space between the jack contacts can be attached to the insulating housing at a narrow pitch, and the composite connector and the communication device to which the composite connector is attached can be reduced in size as a whole.

Further, since it is not necessary to form a conductive pattern corresponding to the jack contact, the number of conductive patterns on the printed wiring board is reduced, and the wiring is facilitated.

Further, since the jack contact and the conductive pad can be electrically connected only by press-fitting the plate-like projection into the slit, both can be naturally electrically connected to each other in the work of attaching to the respective insulating housings.

Further, even if the jack contact rattles due to the insertion and removal of the power plug, the movement is not transmitted to the conductive pad, and even if insertion and removal are repeated, the solder peeling of the solder connection portion with the printed wiring board may occur. There is no.

Further, according to the second aspect of the present invention, since the jack contact and the conductive pad contact each other at at least four different positions, the reliability of the electrical connection can be ensured.

Further, according to the invention of claim 3, according to claim 1,
Alternatively, in addition to the invention of claim 2, when the surface is mounted on the printed wiring board, the number of legs to be solder-connected to the conductive pattern of the printed wiring board is reduced, so that all the legs are mounted on the mounting surface of the printed wiring board. It is easy to align them on the same plane, and it is possible to prevent poor solder connection.

Further, according to the fourth aspect of the present invention, since the plurality of jack contacts are insulated from each other and supported by the insulating housing, the jack contacts can be brought into contact with the corresponding terminals of the multipolar power plug.
