Abstract

PROBLEM TO BE SOLVED: To make the structure simple and prevent cost increase for inserting a telephone unit into the device body steadily by grouping. SOLUTION: The connector 23 can be easily and steadily connected with the connector 15 by guiding the guide hole 24 of the telephone unit 22 into the guide pin 14 of the device body 11. And as the connector 15 of the device body 11 is fixed to the printed circuit board 17 through the boss step portion 18a of the case 12 by the mounting hole 20 loosely, the printed circuit board 17 absorbs the deviations by moving even if there are deviations between the positions of the connectors, and the loose structure can be realized at a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device connecting device for connecting an attached device unit to a device main body via a connector.

[0002]

2. Description of the Related Art For example, in a vehicular emergency notification device, when a sensor detects a vehicle collision or an occupant presses an emergency call button, an emergency notification including the current position information of the vehicle is made via a wireless telephone line. It is sent to the center, and if possible, the crew reports the details of the accident over the phone, and then an ambulance or patrol car is requested to the fire department or police station. In such an emergency notification device, a telephone unit is connected to the device main body through a connector.
When the product is shipped, the telephone unit is shipped fixed to the apparatus main body so as not to come off. However, the user sometimes removes the telephone unit for setting a telephone number and fixes it again.

FIG. 6 shows a conventional connection structure of this kind. The device main body 1 has a unit mounting recess 3 for mounting the telephone unit 2, and a connector 4 is disposed on the back side thereof. A fixing recess 5 for fixing the device unit 2 is formed on the front side of the unit mounting recess 3. On the other hand, the telephone unit 2 includes a connector 6 connected to the connector 4 and a projecting piece 7 for fixing the fixing recess 5 with the screw 8. After the device main body 1 is screwed into a predetermined position of the vehicle via the mounting flange 9, the telephone unit 2 is inserted into the unit mounting recess 3, and the connector 6 is inserted into the connector 4. Is fixed to the fixing recess 5 by the screw 8.

[0004] Since the connection work between the connectors is carried out in a groping state due to the location of the mounting, the telephone unit 2 is connected.
The connector 4 on the side of the apparatus main body 1 has a floating structure that can move up, down, left and right so that the connector 6 and the connector 4 can be fitted well. With this floating structure, the variation in the position between the connectors is absorbed, and the connection in the groping state can be performed.

[0005]

However, in the above-described conventional connector connection structure, in order to securely fit the connector of the device unit into the connector of the device body in a groping state, it is necessary to move the connector of the device body side up and down in the floating structure. There has been a problem that the left and right movement amounts must be large, which complicates the floating structure and increases the cost.

SUMMARY OF THE INVENTION The present invention is to solve such a conventional problem, and it is possible to easily and surely connect a connector of an apparatus unit to a connector of an apparatus body, and to realize a floating structure on the apparatus body side at low cost. It is an object of the present invention to provide an electronic device connection device capable of performing the following.
