Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a bus bar, and more particularly, to a connector for connecting a bus bar that can easily attach / detach a bus bar to / from a terminal without using a separate tool.
In general, a bus-bar is a rod-shaped conductor made of a material such as copper, silver, or tin-plated copper and formed into a bar shape. Such a bus bar can energize a high-capacity current more safely than a copper wire, and is widely used as a wiring member in a power supply device including a battery pack of an electric vehicle.
In recent years, a flexible bus bar having a higher degree of freedom than a bar-shaped bus bar has been widely used in a power source device having a limited space such as a battery pack of an electric vehicle. Such a flexible bus bar can bend a plurality of parts and can be installed at a connection site, and thus the flexibility of installation is high, and it is popular.
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.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a connector for connecting a bus bar, which is capable of easily mounting a bus bar without using a conventional bolt-nut fastening method.
According to an aspect of the present invention, there is provided a connector comprising: a female connector having a slot in which a terminal end of a bus bar is inserted and electrically connected; and an arm connector protrusion protruding outward at a predetermined position out of the outer sides; A male connector provided in the inner diameter of the female connector so as to be able to be drawn in and pulled out, a hollow hole through which the bus bar is forcedly inserted, and a male connector protrusion protruding outward at a predetermined position out of its outer side; And the male connector protrusion and the male connector protrusion integrally connected to the male connector protrusion and the male connector protrusion in a state in which the male connector is drawn into the female connector, A connector for connecting the bus bar can be provided.
Wherein the locking lever includes a projection mounting hole that is fitted in the male connector projection and a projection guide hole formed in an arc shape and fitted in the female connector projection, and rotates the male connector projection about a predetermined angle .
Two male connector protrusions and two male connector protrusions are provided on both sides of the male connector and the female connector, respectively, and the locking lever includes the projection mounting hole and the projection guide hole, A pair of lever plates mounted so as to stand side by side on both sides of the male connector; And a plate bridge integrally connecting the pair of lever plates.
A latching jaw provided on the plate bridge; And a fixing jaw provided at a rear end of the male connector so that the locking jaw can be engaged when the locking lever rotates by the predetermined angle.
The male connector may include a first socket forming a front end portion of the male connector and a second socket forming a rear end portion of the male connector.
At least one hook provided on an outer surface of the first socket; And a hooking hole provided in the second socket so that the at least one hook can be engaged.
The male connector protrusion may be provided on the outer surface of the second socket.
The first socket includes: a connection portion provided to be able to enter into the inner diameter of the female connector; And a fastening part integrally formed with the connection part and provided so as to be able to be inserted into the inner diameter of the second socket.
The fastening portion may include a block formed with the hollow hole at a central portion thereof, and the second socket may include a block fitting portion adapted to prevent the block.
The second socket may include an insertion port which is located on a coaxial line with the hollow hole of the block and is provided so that the bus bar passes from the outside to the inside.
The slot may be provided coaxially with the hollow hole of the block and the insertion port.
The female connector may further include a fixing flange provided in a plate shape along the circumferential direction.
According to another aspect of the present invention, a battery pack including the connector for connecting a bus bar described above can be provided.
According to an aspect of the present invention, since a bolt and a nut are not used as in the past, bus bar connection work can be simplified, thereby shortening the overall electrical connection work cycle.
According to an aspect of the present invention, a bus bar can be easily assembled to a terminal even if there is a terminal in a space in which a tool such as a spanner can not enter.
Further, according to one aspect of the present invention, since the connecting portion between the bus bar and the terminal is not exposed, the safety can be improved.
