Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to devices such as electric pots that are mounted on cars and used, and particularly relates to power connection devices thereof.

(Prior art and its problems) Generally, devices such as electric pots are installed at appropriate locations on the vehicle body so that they can be attached and detached in consideration of water replenishment, etc.; In some cases, while the car is running, the car body and equipment inevitably exhibit different vibration conditions.

In such a situation, if both the device side connector and the vehicle body side connector are installed in a fixed state, both connectors exhibit different vibration conditions while the car is running, which may cause damage to both connectors. As a result, both connectors themselves will be destroyed.Therefore, for practical use, there is a need for a power supply connection device that can adequately cope with vibrations and maintain a stable connection over a long period of time. It was hot.

(Purpose of the invention) The present invention has been made in view of the above points, and provides a power supply connection device that can maintain a stable connection state over a long period of time without being destroyed by vibration.
This makes it easy to put it into practical use.

(Structure of the invention) In other words, the present invention consists of a base fixed to the vehicle body and vehicle-mounted equipment removably installed on the base, which engages with the bottom surface of the equipment and the top surface of the base, respectively. A mechanism is provided so that the equipment can be supported on the base, and the electrode terminal of the vehicle body side connector provided on the top of the base and the electrode terminal of the equipment side connector provided on the bottom of the equipment are connected to each other when the equipment is installed. When connected in this state, a power supply circuit is formed and power is supplied from the base side to the equipment side, and either the vehicle body side connector or the equipment side connector is movable within a predetermined range. It can be set up freely.

(Example) An example of the present invention shown in the drawings will be described in detail below.

Reference numeral 1 denotes a base installed at an appropriate position on the vehicle body 2, and 3 denotes an air pot with a function of boiling water and keeping it warm.
The pot 3 is detachably mounted on the base 1 by means of an elastic support device 4.

The elastic support device 4, as shown in FIG.
A shaft 5 of a bolt or the like installed upright on the base 1, an engagement boss 6 that is fitted onto the shaft 5 so as to be movable up and down and has an engagement protrusion 7 formed on its outer periphery, and the engagement boss 6 and the base. 1 and the shaft 5.
A spring 9 is installed on the outer periphery of the engagement boss 6 and always urges the boss 6 downward; an annular support 10 is installed inside the bottom recess of the pot 3; A plurality of clamp pins 11 are provided so as to be movable around the circumference and arranged at equal intervals in the circumferential direction, and a plurality of clamp pins 11 disposed within the support body 10
1 and a spring 12 that is always biased in the projecting direction, and the air pot 3 is configured by fitting the bottom support 10 to the outer periphery of the engagement boss 6 and engaging each clamp pin 11 with the protrusion 7. By base 1
Place it on top. In this state, the air pot 3 is elastically supported by the muffler 8 and the spring 9. Note that if the air pot 3 is lifted upward with a large force, the clamp pin 11 will move back against the spring 12 and will disengage from the protrusion 7 of the engagement boss 6, and the air pot 3 will not be removed. Can be done.

Reference numeral 13 denotes a device side connector fixedly installed at the bottom of the air pot 3, and has a pair of electrode plates 14. 15 forms a groove 16 into which the electrode plate 14 is fitted;
This is a vehicle body side connector having an electrode receiver 17 provided inside the connector 6, and is movably supported on the base 1. 18 are recesses formed at both ends of the vehicle body side connector 15;
Reference numeral 9 denotes a support fitting erected on the base 1, and the bending piece 20 at the tip thereof is inserted into the recess 18.
The vehicle body side connector 15 is supported so that it can move up and down, left and right, and front and back to some extent within the range allowed by. Reference numeral 21 denotes connectors attached to both sides of the vehicle body side connector 15, made of an elastic material, and connected to the device side connector 1.
Attach to both sides of 3. 22 indicates a power cord.

With the above configuration, the support body 1 of the air pot 3 is now
0 to the outer periphery of the engagement boss 6 on the base 1, the electrode plate 14 of the equipment side connector 13 connects to the vehicle body side connector 15.
The connector 21 fits into the groove 16 of the connector and is electrically connected to the electrode receiver 17 inside thereof, and power is supplied to the air pot 3, while the connector 21 is elastically engaged with both sides of the device side connector 13. The connected state is maintained by sandwiching the connector 13.

Therefore, while the car is running, although the base 1 on the car body 2 side and the air pot 3 exhibit different vibration conditions, the car body side connector 15 can move freely within a certain range with respect to the base 1, so the equipment Since it vibrates integrally with the side connector 13, there is no fear that both connectors 13, 15 will be destroyed due to vibration, and the connected state can be maintained reliably.

In the above embodiment, the vehicle body side connector is movable, but the equipment side connector may be movable. Further, even if the connector is provided on the equipment side connector, similar effects can be expected.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can of course be implemented with appropriate modifications within the scope of the invention.

(Effect of the invention) As described above, according to the present invention, either the vehicle body side connector provided on the top surface of the base or the device side connector provided on the bottom surface of the device is provided movably within a predetermined range. Therefore, even if the vehicle body vibrates, these connectors will not be destroyed, and therefore a stable connection can be provided for a long period of time, making it extremely useful in practical use.
