(First modification)
Hereinafter, various modifications of the present embodiment will be described with reference to the drawings.
FIG. 3A shows the connection device 1 to which the following first modification is not applied, and FIG. 3B shows the connection device 1 to which the first modification is applied. In this modification, as shown in FIG. 3B, ribs (members) 71 are provided to prevent the feeder line 2 from being excessively inserted in the bottom direction of the substantially U-shaped shape of the connection sheet metal 3. However, before describing this modification, the connection device 1 having no rib 71 according to this modification will be described with reference to FIG. In this connection device 1, when the power supply line 2 is pressed further in the bottom direction than the position where the power supply line 2 is sandwiched by the connection sheet metal 3, the connection sheet metal 3 opens in the D direction, and the power supply line 2 is excessively inserted in the bottom direction. The If it does so, the contact of the feeder 2 and the connection sheet metal 3 will become insufficient, and electricity supply between the feeder 2 and the connection sheet metal 3 will become unstable. In addition, since the force with which the connection sheet metal 3 sandwiches the power supply line 2 is reduced, the power supply line 2 is easily detached from the connection device 1.

  On the other hand, in this modified example, as shown in FIG. 3B, the connection device 1 is provided with a rib 71 on the upper end of the case body 52, and the height of the upper surface of the rib 71 is set to The electric wire 2 is formed so as to have the height of the lower surface of the feeder line 2 when the electric wire 2 is sandwiched between the connecting metal plates 3.

In this modification, as shown in FIGS. 4B and 4C, ribs (members) 72 are provided to prevent the feeding line 2 from being inserted excessively in the feeding line insertion direction of the connection sheet metal 3. However, before describing this modification, the connection device 1 having no rib 72 according to this modification will be described with reference to FIG. In this connection device 1, when the power supply line 2 is inserted excessively, the power supply line 2 comes into contact with the mating connection sheet metal 3 and a current is short-circuited. If it does so, since the energization state between the feeders 2 will fluctuate and the state of the magnetic field formed around the connection device 1 will fluctuate, the induced current generated at the current supply destination such as the carrier will not be stable.

  On the other hand, in this modified example, as shown in FIGS. 4B and 4C, the connection device 1 has ribs on the case main body 52 and the lid 53 so as to be positioned at the tip of the feeder line 2. 72 is provided. By adopting such a configuration, even if the feeder line 2 is excessively inserted in the feeder line insertion direction of the connection sheet metal 3, the leading end of the feeder line 2 comes into contact with the rib 72, so that excessive insertion is prevented. . In addition, it is possible to prevent the feed line 2 from moving in the feed line insertion direction due to vibration after the connection device 1 is installed. As a result, the attachment position of the feed line 2 becomes appropriate, and the energization state between the feed line 2 and the connection sheet metal 3 is stabilized.

  The rib 72 for preventing excessive insertion may be provided on the cover 6 as shown in FIGS. Even in the case 5 in which the rib 72 is not provided, the excessive insertion of the feeder 2 can be prevented by providing the cover 72 with the rib 72.

(Third Modification)
FIGS. 6A to 6C show a connection device 1 to which the following third modification is not applied, and FIGS. 7A and 7B are connection devices to which the third modification is applied. 1 is shown. In this modification, as shown in FIG. 7A, a slit 32 for preventing stress from the connection sheet metal 3 to the pin 51 is provided around the through hole 31 of the connection sheet metal 3. Here, before describing this modification, the connection device 1 having no slit 32 according to this modification will be described with reference to FIGS. 6A to 6C. In this connection device 1, when the feeder 2 is inserted into the connection sheet metal 3, the connection sheet metal 3 attempts to open. However, since the pin 51 is in contact with the through hole 31, the connection sheet metal 3 is It is difficult to open, and the pin 51 may be broken by the stress that opens the connection sheet metal 3.

  On the other hand, in this modified example, as shown in FIG. 7A, slits 32 are provided around the through holes 31 except for the bottom portion direction of the connection sheet metal 3. With this configuration, even when the feeder 2 is inserted, the connection sheet metal 3 outside the slit 32 is opened, but the connection sheet metal 3 around the through hole 31 is not opened. No stress is applied to the pin 51. As a result, the connection sheet metal 3 is easily opened, so that the power supply line 2 can be easily inserted into the connection sheet metal 3 and the pins 51 are not broken.

  In addition, this invention is not restricted to the structure of the said various embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, in the embodiment, one connection sheet metal 3 is positioned by one pin 51, but may be positioned by a plurality of pins 51. Further, the pins 51 may be provided on the lid 53 without being provided on the case main body 52, or may be provided on both the case main body 52 and the lid 53.
