Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector device used for connecting an imaging device for an endoscope to a video processor, for example.

[0002]

2. Description of the Related Art As shown in Japanese Patent Application Laid-Open No. 2-124130, a general endoscope connector device has a plurality of rod-shaped male contacts provided on a plug, and a jack (receptacle). ) With the multiple female contacts
The plug and the jack are adapted to be engaged with each other, so that a mechanical and electrical connection is made by fitting a male contact and a female contact.

[0003]

However, as described above, in a general connector device in which a male contact and a female contact are fitted, each of the corresponding contacts is separately fitted, so that it is originally required. The amount of attachment / detachment force is quite large. In particular, if the male and female contacts are tightly and tightly fitted to ensure electrical performance, the contact frictional resistance increases, and the amount of detaching force increases accordingly. In recent years, endoscope devices have become more sophisticated, and the number of contacts in the connector device has increased with the increase in the number of contacts. However, as the number of contacts increases, the amount of the above-mentioned attaching / detaching force further increases, making it more difficult to attach / detach. The problem is getting serious.

[0004] In addition, the endoscope imaging apparatus needs to be subjected to a treatment such as disinfection or sterilization with a chemical solution after use, and at that time, the contact portions become wet. When the liquid enters the fitting hole of the female contact into which the male contact is inserted, the liquid cannot be easily removed. If the contacts remain wet until the next use, there is a possibility that the contact portions are corroded or the contacts are short-circuited and malfunction. In the conventional connector device, there is also a problem in that the operation is cumbersome, for example, a complicated waterproof cap must be attached to the connector portion in order to prevent the contacts from getting wet when disinfecting or sterilizing.

The present invention has been made in view of the above circumstances, and has as its object to secure electrical performance.
It is another object of the present invention to provide a connector device that can easily attach and detach the contact unit and the plug body (the amount of the attaching / detaching force is light) and has good operability. Another object of the present invention is to provide a connector device that can be easily configured to have a structure that can be easily wiped off even when a contact portion gets wet.
