When manufacturing so that it is unified with the body 110 and is not separated, the connection terminal 115, etc. can be built inside the body 110 first and then unified by double injection, etc.; however, on the other hand, the body 110 and the insertion guide member ( In the process of injection to unify 120) first, a sand core, etc. may be inserted and then the connection terminal 115 may be formed by fitting the core, or the connection terminal 115 may be provided inside the body 110 in another method. It is natural that it may be possible.

Additionally, the insertion guide member 120 may be made of the same material as the body 110, but is not limited thereto and may be made of a different material from the body 110.

The pressurizing fixture 130 is a means for pressurizing and fixing the power consumption member (ECM) inserted into the insertion guide member 120 and positioned at the connection terminal 115. The insertion guide member fixed by the pressurizing fixture 130 (120) is in close contact with the connection terminal 115, so that power transmitted from the connection terminal 115 can be supplied more smoothly.

At this time, as shown in the drawing, the body 110 may be provided with a fixing member mounting groove 117 to prevent the fixing member 131 from protruding further than the body 110 to secure the fixing member 131. It is not limited and the fixing member mounting groove 117 may not be provided.

The fixing member 131 can form at least two connection points, including one each at the front end and the rear end. For this purpose, the fixing member 131 is perpendicular to the longitudinal direction of the body 110 at the front end and the rear end, respectively. A fixing piece 131a protruding upward may be provided. That is, the fixing member 131 may form a connection point through each fixing piece 131a provided at the front and rear ends.

For convenience of explanation, the connection point formed at the front end of the fixing member is called the first connection point 132a, and the connection point formed at the rear end of the fixing member is called the second connection point 133a.

Each fixing piece 131a is provided with a pin insertion hole (not shown) to insert a pin, and the first and second rotation links 132 and 133 are connected through the pin inserted into each pin insertion hole to form a connection point. can be formed.

It can be configured to do so. At this time, the first rotation link 132 may form a protruding piece 1321 that protrudes toward the front, and a coupling member coupling hole (not shown) may be formed vertically on the protruding piece 1321.

The second rotation link 133 may be connected to the second connection point 133a of the fixing member 131, that is, the fixing piece 131a provided at the rear end of the fixing member 131, and rotates about the second connection point 133a. It can be configured to do so.

The pressure control lever 134 may be combined with the first rotary link 132 and the second rotary link 133 to form a third connection point 134a and a fourth connection point 134b at the combined portion.

The pressure control lever 134 may be formed to adjust the angle of the first rotation link 132 while rotating about the third and fourth connection points 134a and 134b. At this time, the pressure control lever 134 is located at the end It extends long to the rear, allowing the user to adjust the pressing member 136, which will be described later, with relatively little force.

Meanwhile, a lever handle 1341 made of rubber or the like may be provided at the end of the pressure control lever 134 to prevent injury to the body and expand the control area when adjusting the pressure control lever 134. However, the lever handle 1341 ) may not be available.

The coupling member 135 may be inserted into a coupling member coupling hole (not shown) provided in the first rotary link 132. At this time, the end of the coupling member 135 may protrude through the coupling hole of the coupling member, and the pressing member 136 may be coupled to the protruding end.

Through this, the pressing member 136 is formed to be able to rise or fall according to the adjustment of the pressure control lever 134. Here, the pressing member 136 is positioned at a position facing the connection terminal 115 when lowering. Formed, the power consumption member (ECM) inserted through the above-described insertion guide member 120 is located between the pressing member 136 and the connection terminal 115, and the pressing member 134 is operated by the pressing member 134. When lowering (136), the pressing member 136 can pressurize the power consumption member (ECM) and bring it into close contact with the connection terminal 115, and on the contrary, the pressing member 136 can be pressed by the opposite operation of the pressing control lever 134. When raising, the pressurizing member 136 can release the pressurization of the power consumption member (ECM).

Through adjustment of the pressurizing fixture 130, it can be easier to fix and unfasten the electric power consumption member (ECM), and when fixed, the electric power consumption member (ECM) is in close contact with the connection terminal 115 and connected. Power transmission to the power consumption member (ECM) through the terminal 115 may be smooth.

Meanwhile, the pressing member 136 may be formed of Teflon or ceramic series to have heat resistance to heat generated between the connection terminal 115 and the power consumption member (ECM) and insulation to power, but is limited to these. This does not mean that any material that has sufficient heat resistance and insulation can be used.

In addition, the shape of the coupling member 135 is not limited, and may be formed in a bare shape and fitted into the coupling hole of the coupling member. However, on the other hand, it may form a screw thread (not shown) together with the coupling hole of the coupling member and be fastened to each other. It may be a format, and various other coupling members may be used.

At this time, the elastic member 221 may be connected with one end inserted into the moving piece 223 to minimize multi-directional deformation, and the other end may be inserted into the body 210 for compression and tension in addition to the return direction. The area that can be deformed in multiple directions can be minimized.

For this purpose, elastic member insertion grooves 221a may be provided inside the moving piece 223 and the body 210, respectively.

The fixing chuck 230 is a means for fixing the power consumption member (ECM) that receives power from the power supply cable 240, and is provided in front of the connection terminal 215 so that the power consumption member (ECM) can be inserted. there is. At this time, the fixing chuck 230 can be formed to expand or contract according to the movement of the connection terminal 215. When contracted, it fixes the inserted power consumption member (ECM), and when expanded, it secures the inserted power consumption member (ECM). It may be configured to release the fixation.

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. You 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 inside. That is, the guide member 231 can guide the movement of the connection terminal 215 from a fixed position.

A coupling end 231a may be formed in front of the guide member 231, and the coupling end 231a has a length extending up to the position of the fixing chuck 230 and is provided to surround the outer circumference of the fixing chuck 230. Limiting member 232 may be coupled.

The range limiting member 232 is formed so that its end becomes narrower as it moves forward, thereby limiting the expansion range of the fixed chuck 230 at the provided position. As a result, the fixed chuck 230 uses the power consumption member (ECM). It can only be expanded to the appropriate range that can be inserted.

The fixed chuck 230 is not limited, but may preferably be formed by providing a plurality of chuck pieces 233 that form a right-angled triangle or right-angled trapezoid cross-section on a lateral basis. At this time, 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, when the connection terminal 215 moves forward, the fixed chuck 230 is positioned inside the narrower range limiting member 232 and can be reduced by being compressed by the range limiting member 232, and conversely, When the connection terminal 215 moves backward, it is located inside the wide range limiting member 232 and can be expanded by the 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 of supplying power to the power consumption member (ECM) through the connection terminal 215, and is directly connected to the connection terminal 215. However, preferably, the power terminal 245 may be provided and may be coupled to the connection terminal 215 through the power terminal 245.

At this time, the power terminal 245 is also made of a material that can transmit the power of the power supply cable 240, so that the power supplied by the power supply cable 240 sequentially consumes power through the power terminal 245 and the connection terminal 215. It can be delivered as a component (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 the power terminal 245 is located ( 210) Some may consist of a separate body (not shown).

Through this, the power terminal 245 or the power supply cable 240 can be initially assembled by separating the separation body, and can be more easily replaced by separating the separation body in case of failure or at the end of its life.

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

The insertion guide member 250 can provide a movement space for the connection terminal 215 in communication with the body 210, and the connection terminal 215 is connected so that the fixed chuck 230 is located inside the insertion guide member 250. By forming the length, the power consumption member (ECM) can be prevented from being inserted as deeply as possible.

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

The safety power supply device 200 according to the second embodiment of the present invention configured as described above not only ensures safety, but also is easier to grip and handle, and has a simple structure, making it easy to manufacture and maintain. It has the advantage of being convenient and increasing ease of use.
