実かつ安定に行えることになる。 The operation of the embodiment will be described below. As shown in FIG. 1, the fixing screw 3 is suspended above the screw holes 1a of the fixed terminal plates 16a and 16b, with its head hooked and engaged by the hook 23 provided on the terminal cover 21. Retained. When attaching the fixing screw 3 to the terminal cover 22, insert the fixing screw 3 between the hooks 23 while pushing out the hooks 23 from below the terminal cover 22, so that the hooks 23 close to the fixing screws 3. It is designed to engage the lower part of the neck. In addition, in the embodiment, the width of the holding plate 2, which is inserted near the head of the fixing screw 3 so as not to fall off, is larger than the interval between the screwdriver insertion hole 21 and the hooking claw 23. The fixing screw 3 is integrated into the terminal cover 22 and can be handled as a single block, thereby reducing the number of parts. In this state, appropriate gaps D are formed between the tip of the threaded portion of the fixing screw 3 and the fixed terminal plates 16a, 16b, so that when connecting the electric wire 4 to which the crimp terminal 5 is attached, First, the crimp terminal 5 is inserted through this gap D. Next, the round hole 5 of the crimp terminal 5
a to the screw holes 1a of the fixed terminal plates 16a and 16b, and push the fixing screw 3 downward with the tip of a screwdriver inserted through the insertion hole 22 of the terminal cover 21, the elastic hook 23 is released. bends outward and the holding of the fixing screw 3 is forcibly released by the hooking claw 23 and falls, and as shown in FIG. It abuts against the upper edge of the screw hole 1a of the terminal plates 16a, 16b. When the driver is rotated in this state, the crimp terminals 5 are screwed onto the fixed terminal plates 16a and 16b by the fixing screws 3 and the holding plates 2. Therefore, unlike the conventional example, there is no need to remove the fixing screw 3 before connecting the electric wire 4, and there is no need to hold the fixing screw 3 in a predetermined position when connecting and fixing the electric wire 4. The work of connecting the electric wires 4 can be done extremely easily. In addition, in the embodiment, when the fixing screw 3 comes off the hook 23 and falls down, and the tip of the screw part is engaged with the upper edge of the screw hole 1a of the fixed terminal board 16a, 16b, the upper surface of the head Since the fixing screw 3 is brought into contact with the lower surface of the hooking pawl 23, the fixing screw 3 can be prevented from falling or tilting and is stably held, so that the fixing screw 3 can be screwed more easily. In this case, the fixing screw 3 is securely held with the tip of the screw part slightly biting into the screw hole 1a, so when using a Y-shaped crimp terminal or directly connecting the electric wire 4 without using a crimp terminal. It is also convenient when connecting to Furthermore, the fixing screw 3 held by the hook 23 and the center line of the screw hole 1a are aligned, and since the hook 23 functions as a protrusion for guiding the screwdriver, the fixing screw 3 is aligned with the center line of the screw hole 1a. 3. When using flathead screws, the fixing work can be performed reliably and stably.

るという効果がある。[Effects of the Invention] As described above, the present invention provides a terminal device in which a fixing screw for connecting an electric wire is screwed into a screw hole drilled in a terminal plate disposed in a terminal portion of a housing.
An insertion hole for inserting a screwdriver is made at a position corresponding to the upper part of the fixing screw of the terminal cover that is covered above the terminal board and the fixing screw, and the head of the fixing screw is inserted into the lower opening edge of the insertion hole. A protruding hook is provided to hold the fixing screw so that when the head of the fixing screw is held by the hook, an appropriate gap is formed between the threaded end of the fixing screw and the terminal plate. In addition to setting the length and the formation position of the hook, the hook is made elastic so that the fixing screw can be removed from the hook when the head of the fixing screw is pushed downward with a screwdriver. The fixing screw is held in such a way that an appropriate gap is formed between the tip of the screw part and the terminal plate by the hook provided on the holder, so insert the crimp terminal through this gap and tighten the fixing screw. It can be screwed into the screw hole of the terminal board, and has the effect of making it easier to connect electric wires to which crimp terminals having round holes are attached. In addition, if the fixing screw comes off the hook and falls, and the tip of the screw part engages the upper edge of the screw hole in the terminal board, the top surface of the head touches the bottom surface of the hook. This prevents the screw from tipping over or tilting, and holds it stably.When it is dropped downward and moved to the retracted position, the fixing screw is still attached.
The head is held in place to prevent it from falling or tilting before tightening, and as the fixing screws are tightened, the head is released from being held and can be tightened with a light force. In other words, before tightening the fixing screw, the fixing screw is held in the correct position without tilting, and as soon as you start tightening, it becomes free and can be fixed with a light force. This has the effect of making it easier to screw in the screws.
