This is useful in the conventional example because there is no mechanism for absorbing the positional deviation).

As described above, since the shock absorbing elastic member 33 absorbs the shock, it is possible to prevent the first connector 23 and / or the second connector 25 from being damaged by collision. In addition, since the shock absorbing elastic member 33 absorbs a shock in the vicinity of the first joint 41 and the second joint 50, damage of the first joint 41 and / or the second joint 50 is particularly prevented. can do. Further, since the shock absorbing elastic member 33 surrounds the second joint 50, the shock absorbing state is stabilized, and the damage of the first joint 41 and / or the second joint 50 is more effectively prevented. can do. Furthermore, since the shock absorbing elastic member 33 comes into contact with (contacts with) the above-described distal end surface of the first joint portion 41, the collision between the first joint portion 41 and the second joint portion 50 is more favorably prevented. be able to.

Since there is no permanent magnet as in the conventional example, it is not affected by iron powder and the like (in the conventional example, if iron powder or the like is attached, the iron powder or the like is attached). And it could not be electromagnetically joined). There is also an advantage that a simple structure can be achieved.

Moreover, since the shock absorbing elastic member 86 is sandwiched between the first joint portion 87 and the second joint portion 50 to absorb the shock, it is particularly possible to prevent the first joint portion 87 and / or the second joint portion 50 from being damaged. Can be prevented. Further, since the shock-absorbing elastic member 86 covers the entire front end face of the second joint portion 50, the state of shock absorption is stabilized,
Breakage of the first joint portion 87 and / or the second joint portion 50 can be more favorably prevented. Furthermore, the shock absorbing elastic member 86 is provided with the first joint 87 and the second joint 50.
Between the first joint 87 and the second joint 5
It is possible to reliably prevent collisions between zeros.

Next, still another embodiment of the electromagnetic induction type connector according to the present invention will be described with reference to FIG. 14 and FIG. FIG. 14 is a cross-sectional view showing another embodiment (when the door is normally closed), and FIG. 15 is a cross-sectional view of FIG. 14 in which the door is rapidly closed. The same components and portions as those described above are denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 14 and FIG.
Reference numeral 1 denotes an electromagnetic induction type connector. The electromagnetic induction type connector 91 includes a first connector 93 provided to be able to return and return to a boarding opening 92 of a vehicle body (corresponding to one of the two members described in the claims) of the vehicle, and a door of the vehicle. (Corresponding to the other of the two members described in the claims) and a second connector 83 provided at an edge portion 94. The electromagnetic induction connector 91 of this embodiment is different from the electromagnetic induction connector 81 in that the first connector 93 is provided with elastic members 95, 95 described later.
(See FIG. 8).

The first connector 93 includes the first core 2
6, a first covering member 84, and a pair of elastic members 95, 95. The first connector 93 is connected to the primary coil oscillation drive control device 30 housed in the case 29 via the electric wires 28, 28. On the other hand, the case 35 is connected to the second connector 83 via the electric wires 34, 34.
Is connected to a known rectifier circuit 36 housed in the rectifier circuit 36.

The elastic members 95, 95 are elastically deformed when pressed by a predetermined value or more at the time of contact between the first connector 93 and the second connector 83. , 43, and coil springs 97, 97 provided outside the spacers 96, 96 (the elastic members 95, 95 83 may be provided).

Flanges 98, 98 are formed at one end of each of the spacers 96, 96 so as to restrict the advance of the first covering member 84. Also, the spacer 9
The other ends of the ports 6 and 96 abut the boarding port 92. Reference numerals 99, 99 indicate bolts, which are screwed into screw portions 100, 100 formed in the boarding opening 92 while being inserted through the spacers 96, 96. The coil springs 97, 97
And the boarding port 92, and urges the first covering member 84 in the forward direction.

Reference numeral 101 denotes a guide portion provided at the boarding port 92. The case 29 slides on the guide portion 101 as the first connector 93 retreats. In this embodiment, a lubricant such as grease is applied in order to enhance waterproofness.

The second connector 83 has a bolt 10
The threaded portion 10 formed on the edge portion 94 by the two and 102
3 and 103 are fixed.

In the above configuration, as shown in FIG. 14, when the door is normally closed with respect to the vehicle body, the first connector 93 and the second connector 83 butt. At this time, the first fitting portions 42, 42 and the second fitting portion 5
1 and 51 are fitted to each other for positioning, and the distal end surface of the first joint portion 87 and the shock absorbing elastic member 86 come into contact with each other. Absorbed. And the 1st joining part 87 and the 2nd joining part 50 approach and are electromagnetically joined. If the distance between the first joint 87 and the second joint 50 cannot be kept constant, the coil springs 97, 9 of the elastic members 95, 95 may be used.
7 is elastically deformed and functions to retreat the first connector 93 to keep the interval constant (especially when the door as shown in FIG. 15 is rapidly closed).
Thereafter, when a mutual induction action occurs between the primary coil 38 and the secondary coil 47, power supply from the vehicle body to the door is started.

As described above, in addition to the effects of the above-described electromagnetic induction type connector 81 (see FIG. 8), the electromagnetic induction type connector 91 of the present embodiment has the first connector 93 retracted and the first joint 87 There is an effect that the distance between the second joint 50 and the second joint 50 can be kept constant. This makes it possible to stabilize the power supply efficiency. In addition, it can contribute to prevention of breakage.

In addition, it goes without saying that the present invention can be variously modified and implemented without departing from the spirit of the present invention. That is, in the above, the example of the two members described in the claims is a vehicle body and a door body (a door, a sliding door, a rear hatch). However, the invention is not limited thereto. For example, a tuner and a speaker in audio are two members. Other examples include a door steering (separate body: steering portion) and an automobile seat (separate body: seat portion). It is sufficient that two members need to supply power by electromagnetic induction. In the above description, the supply of electric power has been described, but it is also used for transmitting signals.

[0081]

As described above, according to the first aspect of the present invention, since the shock absorbing elastic member absorbs the shock, the first connector and / or the second connector are damaged by the collision. Can be prevented.

According to the second aspect of the present invention,
An impact can be absorbed in the vicinity of one of the joints of the first connector and the second connector. Therefore, in particular,
The breakage of the joint can be prevented.

According to the third aspect of the present invention,

According to the present invention described in claim 4,
Collision between the joints of the first connector or the second connector can be more favorably prevented.

According to the fifth aspect of the present invention,
The impact can be absorbed at the joint surface of either one of the first connector and the second connector. Therefore, particularly, the breakage of the joint can be prevented.

According to the present invention described in claim 6,
The efficiency of power supply or signal transmission can be stabilized while maintaining the interval between the joints. In addition, it can contribute to prevention of breakage.
