At this time, the fixed chuck 230 may be formed to expand or contract according to the movement of the connection terminal 215, fix the inserted power consuming member (ECM) when contracted, and expand the power consuming member (ECM). It can be configured to release the fixation of.

More specifically, on the outer surface of the connection terminal 215, that is, between the connection terminal 215 and the body 210, a guide member 231 is fastened to the body 210 or fixedly installed to be in close contact with the body 210. can At this time, the inside of the guide member 231 is formed to be larger than or equal to the outer surface of the connection terminal 215 so that the connection terminal 215 can be moved to the inside. That is, the guide member 231 may guide the movement of the connection terminal 215 at a fixed position.

A coupling end 231a may be formed in front of the guide member 231, and a range provided to surround the outer circumference of the chuck 230 by forming a length up to the position of the chuck 230 in the coupling end 231a. A limiting member 232 may be coupled.

The range limiting member 232 is formed such that the end portion becomes narrower toward the front, and may limit the expansion range of the fixed chuck 230 at the prepared position. As a result, the fixed chuck 230 removes the power consuming member ECM. It can be extended only to the appropriate range that can be inserted.

The fixed chuck 230 is not limited, but may preferably be formed with a plurality of chuck pieces 233 forming a right triangle or right trapezoid cross section on a lateral basis. At this time, between the chuck pieces 233 may be connected by a spring 234 that is tensioned to push in the expansion direction or compressed to pull in the contraction direction.

Through this, the fixing chuck 230 can be reduced by being positioned inside the narrower range limiting member 232 and compressed by the range limiting member 232 when the connecting terminal 215 moves forward, and vice versa. When the connection terminal 215 is moved backward, it may be located inside the wide range limiting member 232 and extended by a restoring force of the spring 234 .

As described above, the power supply cable 240 is inserted into the cable insertion hole 211 and is a means for supplying power to the power consuming member (ECM) via the connection terminal 215, and is directly connected to the connection terminal 215. However, preferably, a power terminal 245 may be provided and coupled to the connection terminal 215 through the power terminal 245 .

At this time, the power terminal 245 is also made of a material capable of transmitting power of the power supply cable 240, and the power supplied to the power supply cable 240 sequentially consumes power through the power terminal 245 and the connection terminal 215. It can be transmitted to the member (ECM).

Meanwhile, the safety power supply device 200 according to the second embodiment of the present invention is not shown in the drawings, but like the safety power supply device 100 according to the first embodiment, the body near where the power terminal 245 is located ( 210) may be partly composed of a separate body (not shown).

Through this, the power terminal 245 or the power supply cable 240 may be initially assembled by separating the separate body, and may be more easily replaced by separating the separate body in case of failure or when the service life is over.

In addition, the safety power supply device 200 according to the second embodiment forms a length along an extension line of the body 210 from the front end of the body 210 so that the power consuming member (ECM) is inserted into the chuck 230. It may be configured to further include an insertion guide member 250 for guiding.

The insertion guide member 250 may provide a moving space for the connection terminal 215 communicating with the body 210, and the connection terminal 215 so that the fixed chuck 230 is positioned inside the insertion guide member 250. It is possible to form a length so that the power consuming member (ECM) is not inserted as deeply as possible.

Of course, the range limiting member 232 that limits the expansion range of the fixing chuck 230 is also positioned up to the insertion guide member 250 in the same way.

The safety power supply device 200 according to the second embodiment of the present invention configured as described above not only secures safety, but also has an easier gripping and handling method and a simpler structure, so that manufacturing and maintenance are easy. It has the advantages of convenience and ease of use.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art can implement them in other specific forms without changing the technical spirit or essential features of the present invention. you will be able to understand Therefore, the embodiments described above are illustrative in all respects and are not restrictive.
