BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring board surface mounting connector suitable for mounting on a wiring board by an automatic insertion machine.

[0002]

2. Description of the Related Art
2. Description of the Related Art As electronic devices have been miniaturized, surface mount connectors mounted on a wiring board used for the electronic devices have also been remarkably miniaturized. Therefore, there is a problem that it is difficult to mount the surface mounting connector together with the electronic component on the wiring board by using an automatic insertion machine.

[0003] The present invention solves such a problem of the conventional wiring board surface mounting connector, and also enables repairing when soldering between the contact and the wiring board becomes defective during surface mounting. It is intended to do so.

[0004]

According to the present invention, in order to achieve the above object, a contact mounting portion is provided on one side of a body portion.
A contact is mounted on the contact mounting portion of the resin connector main body in which a board stopper mounting portion is formed on each of both sides on the other side, and a terminal portion of the contact protrudes from the other side through the body portion. In the mounting connector, a suction nozzle contact flat plate is protruded from the other side of the body to cover the terminal of the contact, and the base of the flat plate is formed to protrude downward or upward to be thick. A groove having an inclined surface reaching the thin portion along the width direction of the thin portion is formed on the end face of the connection portion with the thin portion,
The thin part can be separated from the thick part by folding.

[0005]

A flat plate for a suction nozzle projects from the body of the resin connector body so as to cover the terminal portion of the contact. The flat plate for the suction nozzle of the automatic insertion machine contacts the flat plate to suck the connector body. It is arranged on a wiring board. After placement, after soldering the terminal part of the connector contact to the conductive part of the wiring board by reflow, when finding shortage of solder or short circuit due to solder between adjacent terminal parts, press the flat plate upward or downward. Fold the connection between the thin part and the thick part and remove the thin part. Since a groove having an inclined surface reaching the thin portion along the width direction of the thin portion is formed on the end face of the thick portion of the connection portion, it can be reliably folded at the connection portion, and It is easy to manufacture.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
In the drawings, reference numeral 1 denotes a resin connector main body of a female connector, and a contact mounting portion 3 is formed protruding at a central portion of one side of a body portion 2 and board stoppers are provided at opposite side portions of the other side. The fitting mounting portions 4 and 4 are formed so as to protrude, and a flat plate 5 for abutting the suction nozzle that extends into the gap between the mounting portions 4 and 4 is formed so as to protrude from the upper edge of the other central portion. A plurality of contacts 6 are arranged in parallel in the contact mounting portion 3, and a terminal portion 7 protrudes from the other side through the body portion 2, and the flat plate 5 is arranged so as to cover the terminal portion 7.

[0007] The flat plate 5 is formed such that its root portion protrudes downward (or upwards) and is thick. Is formed, and when a force is applied to the thin portion 5b from below, a groove 11 is formed.
As shown in FIG. 3, it is ensured that the connection portion is broken.

The connector main body 1 has a conductive shield case 8 covering the body 2 and the contact mounting portion 3.
9 are provided.

The connector is arranged at a predetermined position on the wiring board by sucking the flat plate 5 with a suction nozzle of the automatic insertion machine, and the re-flow causes the stopper 9 and the terminal 7 of the contact 6 to be connected to the conductive part of the wiring board. Each is soldered,
The connector is attached to the wiring board, and the terminal portions 7 of the contacts 6 are connected to the wiring on the wiring board. If the soldering is defective, the thinned portion 5b of the flat plate 5 is broken off and the soldered portion of the terminal 7 of the contact 6 is repaired.

Although the above embodiment is a female connector, the present invention can also be applied to a male connector that fits the female connector.

[0011]

According to the present invention, since the connector body has the suction nozzle contacting flat plate as described above, even if the connector body is small, it can be easily mounted on the wiring board using an automatic insertion machine. In addition, the base of the flat plate is formed to be thicker toward the lower side or the upper side, and has an inclined surface reaching the thin portion along the width direction of the thin portion at the end face of the connection portion with the thin portion of the thick portion. Since a groove is formed, when a failure occurs in soldering the terminal part of the contact and the conductive part of the wiring board, a force is applied to the thin part upward or downward to connect the thin part and the thick part at the connection part. This has the effect that the connector can be reliably folded and repaired without any support, and the structure of the metal fitting of the connector body having a flat plate is simplified.
