Description

Electrical connector and electrical connector assembly {THE ELECTRIC CONNECTOR AND THE ELECTRIC CONNECTOR ASSEMBLY}

The present invention relates to an electrical connector and an electrical connector assembly having a coupling structure for electrically connecting an appropriate signal transmission medium to a main wiring board. It is about.

In general, in various electrical equipment, a terminal portion of a signal transmission medium made of a flexible printed circuit (FCC), a flexible flat cable (FCC), a coaxial cable, or the like is connected to a main printed circuit board. Electrical connectors are widely used. Such an electrical connector is connected to both connectors by inserting a second connector (plug connector) to which a signal transmission medium such as a coaxial cable is connected to the first connector (receptacle connector) mounted on the main wiring board. In this configuration, the signal is transmitted through a conductive contact arranged in a multipolar phase inside the main body housing.

In such an electrical connector, the outer surface of the main body housing is formed of a metal sheet to reduce the influence of electromagnetic noise from the outside on the transmission signal or to reduce the electromagnetic noise radiated toward the outside. Background Art Conventionally, a configuration in which an electromagnetic shield is covered by covering with a conductive shell having an i-shaped shape has been adopted.

However, in the conventional electrical connector, the outer surface of the main body housing is covered with only the conductive cells, so that the terminal of the above-described conductive contact (conductive terminal), more specifically, the main wiring board is connected. The part is not covered with the conductive cell and is exposed to the outside. Therefore, as the transmission signal becomes higher in recent years, the connection area with the main wiring board cannot ignore the influence of electromagnetic noise from the outside and radiate electromagnetic noise from the connection area to the outside. There is also increasing concern.

In addition, although a conventional conductive tape is attached to the connection portion between the conductive contact and the main wiring board or the conductive cell is extended to cover the portion, in the case of using the conductive tape, it is relatively time to attach the conductive tape. Since this required work process is added, productivity tends to decrease. In the case where the conductive cell is extended and covered, the connection between the conductive contact and the main wiring board cannot be visually confirmed by visual inspection or image inspection, which makes it difficult to inspect or confirm whether the connection is performed properly. There is.

In a conventional electrical connector, a plurality of coaxial cables arranged in a multipolar phase are connected to each other by a ground bar, and a part of conductive cells may be connected to the ground bar by soldering. When the conductive cell and the ground bar are connected by soldering, by heating the soldering material, the flux contained in the soldering material suddenly foams, and the soldering material or flux scatters, and the part other than the original connection part. For example, there is a fear of being attached to the contact portion of the conductive contact to generate an electrical failure.

By providing a conductive cover portion covering the connection portion and covering the connection portion between the conductive contact and the main wiring board at the time of coupling of both connectors, the electronic shielding (shield) is immediately performed on the connection portion, thereby eliminating the increase in the number of manufacturing processes. In addition, since the state of connection at the connection area with the main wiring board is satisfactorily confirmed until the coupling support member is rotated to the engagement action position, the electronic device related to the connection area with the main wiring board is simplified. Shielding can be made good without compromising productivity It can inexpensively increase drastically the reliability of the electrical connector.

In addition, the present invention is a contact portion of the conductive contact when the coupling support member is rotated from the mating open position to the mating action position to maintain the connector engagement state, when the mating support member is rotated to the mating action position in a non-engagement state with the mating connector. Soldering of the contact portion is provided by covering the conductive cover portion and rotating the engagement support member to the engagement position before engagement with the mating connector, thereby covering the contact portion of the conductive contact connected to the mating connector with the conductive cover portion and making it protected. Since it is configured to prevent the adhesion of foreign substances such as ash, and to ensure good electrical connection, the simple structure prevents the adhesion of foreign substances such as soldering material to the contact portion of the conductive contact, and thereby makes the reliability of the electrical connector low. It can greatly increase.

A conductive cover portion 14d 'which integrally connects arm portions 14b and 14b is provided. The conductive cover portion 14d' includes a rotary operation portion 14c outside the rotation radius of the coupling rotary arm 14. Is formed, and the plug connector (first connector) 1 is enlarged so that the conductive cover part 14d 'covers the whole.

The conductive cover part 14d 'which concerns on this embodiment is comprised so that the upper surface and both side surfaces of the said plug connector 1 may be covered, when the engagement rotating arm 14 which is a engagement support member is rotated to "coupling action position." It is. On the other hand, the conductive cover portion 14d 'extends to the front of the ground connecting tongue 13a so as not to cover the ground connection tongue 13a like the conductive cover portion 14d of the first embodiment described above. have.

According to the present embodiment having such a configuration, since the entire connector is covered by the conductive cover portion 14d ', a better electromagnetic shielding (shield) function is obtained and the conductive cover portion 14d' It is comprised by connecting the connecting arm parts 14b and 14b integrally, and can increase the rigidity of the coupling rotary arm (coupling support member) 14.

As mentioned above, although the invention made by this inventor was concretely demonstrated based on embodiment, it is needless to say that this invention is not limited to the above-mentioned embodiment, It can variously deform in the range which does not deviate from the summary. none.

For example, in the above-mentioned embodiment, although the coupling rotary arm 14 which is a coupling support member is provided in the plug connector 1 which is a 1st connector, you may install in the receptacle connector 2 which is a 2nd connector.

In the above embodiment, the conductive cover portion is configured to cover the soldering connection portion of the conductive contact, but may be configured to cover other portions as long as it is a connection portion with the main wiring board.

In addition, although the above-described embodiment applies the present embodiment to a horizontally coupled electrical connector, the present embodiment can be similarly applied to a vertically coupled electrical connector.

In addition, the present invention is not limited to the same connector for coaxial cable as in the above-described embodiment, but is used for connecting an insulated cable connector, an electrical connector of a type in which a plurality of coaxial cables and insulated cables are mixed, an electric wire to which a flexible wiring board, etc. are connected. The same applies to the connector, the board-to-board connector, etc. for connecting the printed circuit boards together.

As described above, the present embodiment can be widely applied to various kinds of electrical connectors used in various electrical devices.
