Abstract

PROBLEM TO BE SOLVED: To connect a connector having contacts more than the number of contacts of a connector receiver to the connector receiver without damaging electromagnetic environmental suitability by using a surface contact type contact as an additional contact. SOLUTION: When a pin 33 is fit to a cutout 22 for positioning, phase matching of a male contact pin 18 of this improved connector 3 with a female contact pin 29 of an improved connector receiver 5 can be conducted. When a male screw 34 of a connector receiving cylinder 25 is screwed to a female screw 23 of a mounting ring, a male contact pin 18 is inserted into a female contact pin 29, and an electric signal transmission circuit of a video camera and a signal processing circuit within a signal processing device are connected. Since the form of two additional contacts is a surface contact type having contact plates 19, 29 on the improved connector 3 side and contact surfaces 30, 31 on the improved connector receiver 5 side, when the improved type connector 3 is connected to a conventional type connector receiver, additional two contacts come in contact with the surface of a third insulator of the conventional type connector receiver.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera connector device having a male / female fitting type electric contact.

[0002]

2. Description of the Related Art A connector device for connecting a video camera and a signal processing device thereof has an electrical contact of a male and female fitting type. If the number of electrical contacts of the device increases, the compatibility of the conventional signal processing device with the conventional video camera can be used. ,
The contact portions other than the additional contact portion can be achieved by arranging the same arrangement as that of the conventional type and using the same mechanical connection mechanism of the connector and the connector receiver.

However, there is a case where it is desired to connect an improved video camera to a conventional signal processing device, knowing that the additional function cannot be used. In this case, it is necessary to connect using a conversion adapter that reduces the number of contacts of the connector of the improved video camera to the number of contacts of the connector receiver of the conventional signal processing device.

[0004]

SUMMARY OF THE INVENTION For the above reasons,
When the video camera and the signal processing device are connected via the contact number conversion adapter, the number of connection / disconnection portions of the signal circuit is increased to two as compared with the case where the video camera and the signal processing device are directly connected. , The contact portion of the contact is almost doubled. This significantly increases the probability that a problem such as poor contact of the contact occurs mechanically. In addition, the number of locations where electromagnetic radiation noise is generated from the contact surface increases, and E
Many measures for MC (electromagnetic compatibility) will be required. As a result, the manufacturing cost is increased, and moreover, even if the standard value of EMC cannot be cleared. In addition, the user has to purchase an extra conversion adapter, which increases the cost burden, and also necessitates a new storage space for the extra conversion adapter, which complicates management. Occurs.

[0005] The present invention has been made to solve the above-mentioned problems.
Provided is a video camera connector device that can connect a connector having more contacts than the connector receptacle has to the connector receptacle without deteriorating electromagnetic compatibility, and further improves user handling. To improve.

[0006]

According to the present invention, a connector of a video camera having means for converting an observed image into an electric signal and transmitting the electric signal is connected to a connector receiver provided in a signal processing device for processing the electric signal. By being inserted into and removed from
In a video camera connector device having male and female fitting-type contacts for connecting a circuit between the video camera and the signal processing device, a contact is added when the video camera and the signal processing device are improved, and the added contact is added. The contact is a surface contact type contact.

The surface contact type contact added to the connector of the improved video camera according to the above-mentioned configuration is used when the improved video camera is connected to the improved signal processing device. It is connected to a surface contact type contact added to the receiver. Further, since the contact added to the connector of the improved video camera is a surface contact type, when the connector of the improved video camera is connected to the connector receptacle of the conventional signal processing device, It comes into contact with, for example, a plane portion of an insulator (not provided with a connector receiving contact or the like) of the processing apparatus. Therefore, despite the addition of a contact point due to an improvement in function, the connector of the improved video camera can be directly connected to the connector receiver of the conventional signal processing device without using an adapter or the like.
