On the other hand, when connecting the bus bar to the terminal of the battery pack, the bus bar is fixed to the terminal using bolts and nuts. For example, to connect an existing bus bar to a terminal with a bolt-nut fastening method, first make a tapped hole in one end of the bus bar, insert it into the bolt-type terminal, and tighten the nut again. Since both ends of the bus bar must be connected to the receiving terminal and the discharging terminal, two bolt-nut fastening is required per bus bar.

Therefore, in order to assemble a plurality of bus bars to a power supply unit, it takes a lot of time to perform the bolt-nut assembly work repeatedly, and the work takes a long time. In addition, when the torque is high or incorrectly assembled during the assembling process, damages may occur on the threads, which often results in discarding or reworking of the product.

In order to fasten the bolt and the nut, it is necessary to use a tool such as a spanner. However, there is a problem that it is difficult to install a bus bar in a power supply device in which a tool can not be inserted. As a result, in the case of an electric vehicle in which the space for installing the battery pack is insufficient, it may be difficult to design the battery pack in consideration of the above situation.

The locking lever 300 is configured to rotate in a direction opposite to the projection 120 of the female connector 100 by the rotation of the male connector 200. In this embodiment, the locking lever 300 is configured to rotate about the projection 222 of the male connector 200, The male connector 200 may be configured to draw the projection 222.

More specifically, the locking lever 300 includes a pair of lever plates 310 mounted in parallel on both sides of the male connector 200, and a plate bridge 320 connecting the upper ends of the lever plates 310 do. The lever plate 310 includes a projection mounting hole 311 and a projection guide hole 312. The locking lever 300 can be mounted on the male connector 200 by fitting the projection mounting hole 311 into the male connector 200 protrusion 222.

The projection mounting hole 311 is formed in a substantially central portion of the lever plate 310 so as to correspond to the head portion of the protrusion 222 of the male connector 200, So that it can be fitted only. 5, when the locking lever 300 rotates and the projection mounting hole 311 is turned relative to the head portion of the male connector protrusion 222, the lever plate 310 contacts the head of the male connector protrusion 222 And it does not fall out.

Meanwhile, the protrusion guide hole 312 has an arc shape extending from one side of the edge of the lever plate 310 to a position adjacent to the protrusion mounting hole 311. 3, protrusion guide holes 312 are formed in the protrusion mounting holes 311 from a position spaced a predetermined distance in the horizontal direction (X axis direction) to a position just under the protrusion mounting holes 311 It can be formed into an arc shape having a curvature.

The lever plate 310 further includes a protrusion inlet 313 provided at a rim for inserting the female connector protrusion 120 into the protrusion guide hole 312 in the inserting direction (X-axis direction) of the male connector 200 . The protrusion inlet 313 can communicate with the protrusion guide hole 312.

With this configuration, the female connector protrusion 120 can be connected to the lever plate 310, and the female connector protrusion 120 can be pulled by rotating the lever plate 310. That is, when the female connector protrusion 120 is pulled into the protrusion inlet 313, when the lever plate 310 is turned clockwise, the female connector protrusion 120 is pulled, and the protrusion 120 is pulled from one side of the protrusion guide hole 312 The female connector 100 is pulled in the direction of the male connector 200.
