Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal connecting device that prevents screws from falling off, and particularly to a terminal connecting device that stably holds screws that have been defeated in a movable member in two positions: an upper limit position and a lowered position.

This type of conventional terminal connection device has a structure in which a movable member that supports screws for fixing the terminal and is slidably supported across the terminal board is constantly pressed outward by a helical spring. Because of this, the helical spring is constantly pressing the movable member, and when screwing the screw into the female thread of the terminal board, the lead wire must be fixed while pressing against the restoring force of the spring. Therefore, when a large number of terminal connecting devices are assembled together, it is necessary to individually fix the lead wires against the restoring force of the spring, which makes the work very cumbersome.

This invention was developed with the aim of solving the above-mentioned drawbacks and providing an inexpensive product by reducing the number of parts used.

Embodiments of the present invention will be described below with reference to drawings.

FIG. 1 shows a front view of an embodiment of the invention. The terminal block is approximately 1 digit plus 1,000 pieces with an integrated area, and includes a partition section 2 to ensure electrical insulation from other terminal connection devices adjacent to each other, and a central partition wall that divides the partition section into left and right halves. 3. The left side space 4 and the right side room 5, the center space 5 provided under the partition wall 3, and the space 4 on the left and right side of the partition.
. Elastic barrier 6 erected to form vertical grooves 63 and 64
5, 66, recessed grooves 63a and 64a extending upward from the vertical grooves 63 and 64, and a convex portion 7 and a recess on its back surface for direct connection with another adjacent terminal connecting device. Place (
(not shown) etc. are integrally connected to Iff=r force. Terminal board 8
is a rectangular flat plate made of a conductor supported by the central partition wall 3 and left and right pedestals 41.51, and has female threads 81.9 on both left and right sides.
2 is engraved, and notches 83 and 84 are formed facing the partition portion 2 (1111) for passing the movable members 9 and 10. The movable members 9 and 10 are left-right symmetrical, and each Pressing parts 91 and 101 are formed on the upper horizontal piece.

- The neck of a screw 11 with an open end turned into the center hole of +101 and the spring washer 12 are rotatably supported. Also press l+: hanging piece 92 from one end of part 91.101.
, 102 extend downward, and the middle portion thereof is slightly protruded from the other portions to form the groove 63a or 164.
When forming the guide portions 93 and 103 that can be slidably inserted into the interior of a, the lower ends of the hanging pieces 92 and 102 are made to extend in the substantially right angle direction Vr, and the V-shaped valley-shaped bent portion 94 is formed. , 10
4 is formed. In this invention, the bent portion 94,
104 is formed to be slightly thicker than the width L1 of the vertical groove 63.64, and when the movable members 9 and 10 are attached to the terminal block 1 in the step 11 described later, the bent portions 94 and 104 are In the vertical grooves 63 and 64, the 1st floor of the vertical groove is dynamically seasoned. In the procedure for attaching the movable members 9 and 10 to the terminal block 1, as shown in FIG.
, 10 at symmetrical position l/! to TEi-l8. ', and each hanging piece 92, 102 is placed so that the notch A83.9 of the terminal board 8
Inserted into 4? From the front side of the terminal block 1,
Pushing it together with the terminal plate 9 into a predetermined position 1/i'1 fits it.

The left side of FIG. 1 shows a state in which the lead wire is not connected. The lower end bent portion 94 of the OJ@ parts 9 is at the upper limit position where it contacts the terminal plate 8. In this situation,
Since the elastic force of the elastic barrier 65 acts in the direction of arrow A, a force in the direction of force A' is applied to the movable member 9. This prevents the movable member 9 from falling in the outward direction. In this state, the pressing part 9 of the movable member 9 with 11 screws
1, the tip of the screw is opposed to the screw tip 81, and a distance of 11 mm is created between the tip of the screw and the surface of the terminal plate 8F. The right side of FIG. 1 shows the state in which the lead wire 13 is connected. The lead terminal is sandwiched between the terminal plate 8 and the push FE section 101, and the movable member 10 has been lowered to the lower limit position.

This invention has the feature that the state in which it is not screwed can be changed in two ways. That is, as shown in FIG. 3(a), when the lower end bent portion 94 of the movable member 9 is at the upper limit @ where it contacts the terminal plate 8, the elastic force of the elastic barrier 65 causes the elastic force to move in the direction of arrow A. The movable member 9 is stably held by receiving the force. VC,l: As shown in FIG. 3(b), the lower end of the screw 11 is placed on the terminal plate 8. In the lowered position where the movable member 9 is in contact with the upper surface of the movable member 9, the movable member 9 is stably held in the same way as described above.

Therefore, when the user (d) is pulled up to the state shown in Fig. 3 (a1), the lead wire 13 is inserted, and the movable member 9 is pressed down, it will be in the lowered position shown in Fig. (1) When tightening the screw 11 in the linear state shown in the figure, at this time, the movable member 9 and its guide portion 93 are in the groove 63al/l'', so the force of sliding along the groove 63a is The state shown in FIG. 3(C) is obtained.While this screw tightening is being performed, the work can be performed without being affected by the elastic barrier 65 on the movable member 9.

As described above, this invention is designed to hold the screw that has been lost to the movable member stably in two positions, the upper limit position and the lowered position. When connecting wires, first raise all the movable members of the terminal connection device to the state shown in Figure 3 (a), then insert the lead wires one after another. If you hold it in place and tighten the screw after one use, the lead wire can be connected during the production process, so you can connect the lead wire of the terminal connecting device that was previously installed in the WR1. It is something that

Further, according to the present invention, the elastic barriers 65, 66 are integrally formed with the terminal block 1 to stably hold the movable members 9, 1° in the above-mentioned bistable positions, thereby minimizing the number of parts. Please provide cheap products.

Furthermore, since the number of parts is small and the structure is simple compared to the conventional example using a twisted, helical fine spring, etc., it is extremely difficult to assemble each part.

At the bistable position K of the movable member 9.10, the elastic force of the elastic barrier 65.66 acts in a direction to prevent the movable member from collapsing, so when connecting the lead wires, This provides technical effects such as easy lead wire connection work without the fear of tilting the tip of the screw.
