Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to and the benefit of Korean Patent Application No. 10-2017-0105807, filed on Aug. 22, 2017, which is incorporated herein by reference in its entirety.

FIELD

The present disclosure relates to a high voltage connector capable of stably fastening a fuse without using a separate component.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Recently, a hybrid vehicle which adopts a motor driving source as an auxiliary power source has been introduced. This hybrid vehicle may reduce exhaust emissions as well as improve fuel efficiency.
The hybrid vehicle can travel in an Electric Vehicle (EV) driving mode which uses only the power of a motor by transferring the power of the motor to a transmission. The hybrid vehicle can also operate with a hybrid driving mode which uses the driving power of an engine as an auxiliary power source. Accordingly, the hybrid vehicle may contribute to improving fuel efficiency and reducing exhaust emissions.
The hybrid vehicle may include a motor, a Main Control Unit (MCU) for controlling the motor, a high voltage battery to supply power to the motor, etc., and use a high voltage connector as means for electrically connecting the individual components.
In an inside of the high voltage connector, a fuse is fastened, and the fuse is assembled in a separate component and then coupled to the inside of the high voltage connector together with the separate component.
In order to replace the fuse which is assembled in the separate component and then coupled to the inside of the high voltage connector, the separate component is disassembled from the high voltage connector, and then a matching terminal connected to the fuse is released, which may make replacement work difficult.
The fuse may be fastened to the terminal by soldering in order to stably fasten the fuse inside of the high voltage connector. However, in this case, when the fuse is damaged, both the fuse and the terminal should be replaced.

FIG. 7 shows a bottom of the first cover in some forms of the present disclosure, and FIG. 8 is a cross-sectional view showing a state in which a fuse is fastened by a fixing clip and a fixing rib.
As shown in FIGS. 7 and 8, the first cover 160 may include the first fixing rib 161 supporting the first fixing groove 135 formed in the first fixing clip 133 of the bus bar clip 130 to fasten the fuse 120 fastened to the first fixing clip 133 to prevent the fuse 120 from being separated, and the second fixing rib 162 supporting the second fixing groove 143 formed in the second fixing clip 141 of the bus bar clip terminal 140 to fasten the fuse 120 fastened to the second fixing clip 141 to prevent the fuse 120 from being separated (see FIG. 3).

The second housing 220 may include a first extension portion 221 surrounding a rear part of the insertion portion 211, and a second coupling hole 223 formed in the first extension portion 221 to couple the second housing 220 with the second cover 230 through the bolt B.
The second cover 230 may include a second extension portion 231 surrounding a front part of the insertion portion 211, and a second coupling hole 233 formed in the second extension portion 231 to couple the second cover 230 with the second housing 220 through the bolt B.
The first wire W3 and the second wire W4 may be fastened by a holder 250, and the holder 250 may be coupled with an end of the insertion portion 211.
A shield cover 240 for fastening the shielding wires 260 may be coupled with an outer circumference surface of the insertion portion 211, and the shielding wires 260 may be fastened on the shield cover 240 by a clamp 270 to surround the first wire W3 and the second wire W4.
In order to couple the second housing 220 with the second cover 230 by the bolt B, the shield cover 240 coupled with the insertion portion 211 may include a first through hole 241 formed at a location corresponding to the second through hole 213 formed in the insertion portion 211.
Accordingly, the bolt B may be inserted through the first coupling hole 233, and the bolt B inserted in the first coupling hole 233 may be coupled with the second coupling hole 223 through the first through hole 241 and the second through hole 213, so as to couple the second housing 220 with the second cover 230.
In some forms of the present disclosure, since the fuse can be fastened without using a separate component, the fuse can be easily replaced.
Also, the assembly process of the fuse can be improved, thereby increasing product productivity.
Also, the number of components can be reduced, resulting in miniaturization of the high voltage connector.
Also, since the fuse and the wires are provided in separate partitioned spaces, insulating distances can increase, resulting in miniaturization of the high voltage connector.
Also, since the fuse is stably fastened, a fire that may break outs due to a short may be reduced.
Since it is difficult to replace the fuse without separating the high voltage connector from a power source, the number of accidents can be reduced as well.
The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the substance of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
