[ (320). As described above, the fitting member 326 has a large area enough to cover the cartridge 310, so that the cartridge 310 does not fall outside the fixing block 320.

As the handle 318 moves toward the other end of the guide rod 314 by the pushing member 316, the housed terminals are pushed out. The outermost terminal of the push-out terminals is first seated in the terminal seating hole 162. Further, the head portion T 'of the terminal is supported by the guide pin 158 and stopped. The terminal at this time becomes a crimp terminal.

In addition, the standby terminal in the immediately following order of the crimp terminal, that is, the standby terminal at the best rank, is supported by the support pin 334. Therefore, the best standby terminal does not protrude toward the terminal seating hole 162.

19 to 20 are views showing that the first main lever and the second main lever move from the unlocking position to the tightening position when an external force is applied to the first main lever and the second main lever. Figs. 21-24 show inserting the terminals into the terminal seats before crimping the terminals. Figures 21 and 22 are from the front, and Figures 23 and 24 are from the rear. Figures 25 to 28 show the crimping of the terminals. 25 and Fig. 26 are viewed from the front, and Figs. 27 and 28 are viewed from the rear.

Hereinafter, the process of pressing the terminal will be described with reference to FIGS. 19 to 28. FIG.

When the terminal is placed in the terminal seating hole 162, both sides of the terminal are supported by the guide pin 158. The cable C with the cover removed is inserted into the through hole of the tail portion T "of the terminal. When an external force is applied and the first main lever 110 and the second main lever 120 are moved from the unlocking position to the tightening position The first auxiliary lever 130 and the second auxiliary lever 140 are axially coupled to the lower end of the pressing member 150 so that the pressing member 150 is moved downward from the standby position to the pressing position, So that the user can press the terminal by lowering the pressing member 150 even with a small force.

The crimping member 150 presses the crimping terminal while the crimping member 150 is lowered. The crimp terminal is squeezed and the cable C is connected to the crimp terminal.

When the compression bonding of the compression terminal is completed, the external force of the first main lever 110 and the second main lever 120 is removed. The first main lever 110 and the second main lever 120 move from the tightening position to the unlocking position. The pressing member 150 is moved upward by the spring 170 from the pressed position to the standby position.

Since the guide pins 158 also rise together along the pressing member 150, the pressing terminals are no longer supported. Therefore, the crimp terminal to which the cable is connected can be pulled out from the step seating hole 162. Although not shown, the support pin 334 descends and the best standby terminal is seated in the terminal seating 162. At this time, the best standby terminal becomes a new crimp terminal to be crimped. In this way, a plurality of terminals can be sequentially supplied to the terminal seat 162 and connected to the cable.

The operation of the release preventing unit 200 will be described below. 29 to 33 are views sequentially showing the operation of the release preventing unit.

When the pressing member 150 moves downward from the standby position, the elastic member 230 descends while the hand 232 is opened outward. When the pressing member 150 reaches the pressing position, the second hook 236 is caught in the supporting groove 228. When the pressing member 150 moves upward in the pressing position, the elastic member 230 moves up with the first placing member 210 while the second hook 236 is caught in the supporting groove 228.

This will be described in more detail below. 29, when the pressing member 150 is in the standby position, the first hook 234 of the elastic member 230 is located at the upper portion of the supporting protrusion 214 and is not caught by the supporting protrusion 214. [

Referring to FIG. 30, when an external force is applied to the first main lever 110 and the second main lever 120 and is moved from the release position to the tightening position, the compression member 150 descends from the standby position toward the compression position. At this time, the elastic member 230 fixed to the body 322 of the pressing member 150 also descends. On the other hand, the first mounting member 210 fixedly coupled to the support block 160 does not descend.

The hand 232 is lowered along the second mounting member 220 while the elastic member 230 is lowered so that the elastic member 230 is opened to both sides of the hand 232 along both side surfaces of the extension portion 226 . The second mounting member 220 moves down together with moving within the elongated hole 212 of the first mounting member 210. The first hook 234 is hooked on the support protrusion 214 of the first mounting member 210 and descends.

Also, even if the external force applied to the first main lever 11 and the second main lever 120 is removed during the compression, the elastic member 230 does not move up and hung by the support protrusion 214. This will be described in more detail. If the user removes the external force applied to the first main lever 110 and the second main lever 120 before the pressing member 150 reaches the pressing position, The main lever 120 returns to the unlocking position and the pressing member 150 also moves upward to the standby position. In this case, the crimping portion 156 can not sufficiently crimp the terminal, so that the cable is not firmly coupled to the terminal. Therefore, even when the external force of the first main lever 110 and the second main lever 120 is removed before the pressing member 150 reaches the pressing position, the first main lever 110 and the second main lever 120 ) Does not return to the release position. That is, the pressing member 150 is prevented from returning to the standby position.

When the support protrusions 214 are plural, the support protrusions 214 are engaged with any one of the plurality of support protrusions 214. The plurality of support protrusions 214 allow the first hooks 234 to be stepped on. Or terminals of different sizes, so that cables can be connected.

Specifically, the diameter of the tail portion T "of the terminal to be pressed is different, and the depth at which the press portion 156 presses the tail portion T" of the terminal is different. That is, the pressing position of the pressing member 150 is different. In this case, the supporting protrusions 214 may be formed in multiple stages so that they can be suitably used.

Referring to FIG. 31, when an external force is sufficiently applied to the first main lever 110 and the second main lever 120, the pressing member 150 reaches the pressing position. The insertion portion 222 of the second mounting member 220 reaches the lower end of the elongated hole 212 of the first mounting member 210. Thus, the second mounting member 220 is blocked by the lower end wall of the elongated hole 212 and is no longer moved. At this time, the elastic member 230 is supported and fixed to the second mounting member 220 while the second hooks 236 are inserted into the pair of support grooves 228 provided on both sides of the extending portion 226. The second hook 236 is positioned below the support protrusion 214 so that the second hook 236 is not caught by the support protrusion 214. That is, only when the pressing member 150 is between the standby position and the pressing member 150, the first hook 234 is caught by the supporting protrusion 214.

32 and 33, when the external force applied by the user to the first main lever 110 and the second main lever 120 is removed after completing the terminal crimping, the pressing member 150 is lifted, (230) also rise together. Since the elastic member 230 is coupled to the support groove 228 of the second mounting member 220, the second mounting member 220 also rises. The second mounting member 220 returns to the initial position after colliding with the lower surface of the support block 160 or with the insertion portion 222 colliding with the upper end of the slot 212. The first mounting member 210, the second mounting member 220 and the elastic member 230 may be positioned at an initial position before the user exerts an external force on the first main lever 110 and the second main lever 120, .
