Description

Electrical connector and electrical connector assembly

The present invention relates to an electrical connector and an electrical connector assembly including a fitting structure for electrically connecting an appropriate signal transmission medium to a main wiring substrate.

Generally, among various electric machines and the like, an electrical connector is widely used, which is an FPC (Flexible Printed Circuit) or an FFC (Flexible Flat Cable), or a signal transmission medium composed of a coaxial cable or the like. The terminal portion is connected to the main printed wiring substrate. The electrical connector constitutes a second connector (socket connector) to which a signal transmission medium such as a coaxial cable is connected, and is inserted into a first connector (plug connector) mounted on the main printed wiring board. In the manner of fitting between the two connectors, signal transmission is performed via conductive contacts (conductive terminals) arranged in a multi-pole shape inside the body casing.

In such an electrical connector, in order to reduce the influence of electromagnetic wave noise from the outside on the transmitted signal, or to reduce the electromagnetic wave noise radiated toward the outside, it is conventionally adopted to cover the body with a conductive shell made of a thin metal plate. The outer surface of the outer casing is electromagnetically shielded (shielded).

However, in the conventional electrical connector, the outer surface of the body casing is configured to be covered only by the conductive casing, and the terminal portion of the above-mentioned conductive contact portion (conductive terminal), more specifically, the connection to the main wiring substrate The portion is exposed to the outside without being covered by the conductive case. Therefore, in particular, in recent years, with the high frequency of the transmission signal, the connection portion with the main wiring substrate is affected by the electromagnetic noise from the outside, and the electromagnetic wave noise from the connection portion is radiated to the outside. It has also gradually increased.

Further, a conventional person may have a conductive tape attached to a connection portion between the conductive contact portion and the main wiring substrate, or may extend the conductive case to cover the portion. However, when a conductive tape is used, it is necessary The additional troublesome work steps of attaching the conductive tape tend to result in a decrease in production efficiency. Further, when the conductive case is extended and covered, the connection portion between the conductive contact portion and the main wiring substrate cannot be confirmed by visual inspection or video inspection, and it is difficult to check whether or not the connection is successful.

In addition, in the conventional electrical connector, a plurality of coaxial cables arranged in a multi-pole shape are connected by a ground bar, and the ground bar is welded to a part of the conductive housing, but When the conductive case and the grounding bar are welded in this manner, since the flux contained in the solder material is rapidly foamed by heating the solder material, the solder material or the flux is dispersed and adhered to the original connecting portion. The portion, for example, adheres to the contact portion of the conductive contact portion, and there is a problem that an electrical failure occurs.

At this time, in the conductive case 23 provided in the receptacle connector (second connector) 2, the locking portion 23b is provided to protrude beyond the longitudinal direction of the connector, and is rotated to the "fitted position". The connecting arm portion 14b of the pivoting arm (fitting holding member) 14 is lightly fitted to the locking portion. Further, as described above, when the plug connector (first connector) 1 is fitted to the receptacle connector (second connector) 2, the fitting rotary arm 14 is rotated to the "fitted position". In the vicinity, the connecting arm portion 14b provided in the fitting rotating arm 14 is rotated to extend beyond the protruding portion of the locking portion 23b. In this manner, after the connecting arm portion 14b of the fitting rotating arm 14 spans the locking portion 23b, the locking portion 23b is elastically pressed against the upper surface side of the connecting arm portion 14b of the fitting rotating arm 14, thereby making the fitting rotating arm The whole of 14 becomes elastically held in the "chimeric position". In this manner, when the plug connector (first connector) 1 is fitted to the receptacle connector (second connector) 2, the fitting rotary arm 14 is rotated from the "fitted open position" to the "chiming effect". In the position, the two connectors 1 and 2 are not separated from each other and can be kept in a fitted state.
