Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a terminal connecting device, and particularly to a terminal connecting device in which screws do not fall off.

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. This has the disadvantage that the spring chamber for housing the helical spring becomes larger, and since the helical spring is constantly pressing against the movable member, it is difficult to resist the restoring force of the spring when screwing the screw into the female thread of the terminal board. There was a drawback that the terminal had to be fixed while pressing the screw.

The present invention was invented with the aim of solving the above-mentioned drawbacks.

Hereinafter, four embodiments of the invention will be explained with reference to the drawings. FIG. 1 shows an I-- plane view of an embodiment of the present invention.

Terminal block body + 1='bu → Sujisono 7ζ: 2,! :li
It is integrally molded and β7 ini 1! Other terminals to be connected 11.11. : To ensure electrical isolation 1, place A1 cut part 2, A1 cut part 1 minute to the left A7. central bulkhead 3,

and i1. The sliding wall 5, the rail attachment part G provided below the partition part 2, and the corner contact hole? .

A convex portion 7 for fitting with another terminal connecting device and a recess (not shown) on its back surface are integrally formed.

The terminal board 8 includes the central partition wall 3 and the left and right end walls 4, 5! This supported λq electric body has a round rectangular shape T) on both the left and right sides 1f1.
Female threads 9A and 9B are carved into l+, and are in contact with the middle east bulkhead.

A notch 2) is formed for passing the movable member 10A, ]OF. Movable member 10Δ,]O[:E,).

It has a right symmetrical shape. To explain this for 10Δ, a V-shaped valley-shaped movable spring receiving portion 11 that is perpendicular to the displacement direction is provided in the near Mf portion located inside the terminal (A and γ) of the terminal plate 8. A suppressing portion] 2 parallel to the terminal plate 8 is provided at the outer end, and the pressing portion 12
Insert the neck of screw 13 and spring washer I4 into the center hole of
is rotatably supported.

At predetermined positions on the left end wall 4 and right end wall 5 of the terminal block main body 1,
V-shaped valley-shaped fixed spring receivers 15A, 1513 perpendicular to the displacement force 1itl of the movable member are provided opposite to the movable spring receiver, and compression springs 16A, 16 are provided between the two spring receivers.
B is fitted.

The shape of this compression spring 16Δ or 16B is as shown in Fig. 2: fal JH spring, fb) a leaf spring with a slit in the longitudinal direction, and (c) a leaf spring with a slit in the center of the leaf spring.
A slit is made in the i direction, and the left and right sides are bent into a parallel shape, (dl loop-shaped wire spring, (0
It can be implemented with various shapes and structures, such as a wire spring with one and both ends being free ends, (fl 2,000-wound wire spring, fgl rectangular wire spring, etc.).

The left side of FIG. 1 shows a state in which the lead wires are not connected. Due to the restoring force of the spring 16A, the movable spring receiving portion 118 of the movable member 10A is in contact with the terminal plate 8 at the "-" limit position, and the screw I3 is in the movable portion 4. It does not fall off from the pressing part 12 of t10Δ, and the tip of the screw faces the female thread. This shows a state in which the right-hand side c OLED brocade 17 in FIG. The lead terminal is sandwiched between the terminal plate 8 and the pushing part 12, and the movable member 10B is moved to the 1st position. Fi! It has descended to i'i.

The present invention has a feature that even if the shape of the movable member 10 is the same, depending on the length of the fuse 13 or the height of the fixed spring receiver 15, the state can be changed in two ways: whether it is not screwed or not. That is, as shown in FIG.
J of 0:, m 4r' is set (1) The distance between the tip of the screw J3 and the tenth surface of the terminal plate 8 is 7!1, and the distance between the movable spring receiving part 11 and the fixed spring receiving part 15 at that time is When the length in the vertical direction is 12, if β1〉p2 is satisfied, at the two positions shown in the fat diagram in Figure 3, t7R (up position and the lowered position shown in Figure 3 (+1)). The movable member 10 is held stably.When the movable member is above the neutral point, there is a neutral point J1.i where the shell of the compression spring 16 becomes small between these two positions. The spring acts on the movable member in the direction J2, and when the movable member is below the neutral point, the spring acts on the movable member with a downward force.

Therefore, when the user is pulled up to the state shown in Fig. 3 (Fig. 81), the lead wire is inserted, and the movable member 10 is pressed down, the state shown in Fig.
The restoring force of 6 acts in the direction that pinches the lead wire, and even while tightening the screw, the work can be done without resisting the force of 6. Moreover, while tightening the screw, the spring force is Since it continues to act in the direction of tightening the screw, there is no risk of the screw loosening due to vibration, etc.

As shown in FIG. 3(C), in the case of /l < β2, even a slight upward force acts on the movable member when the screw is not screwed into the female thread, but when the screw is in the fastened state, As shown on the right side of Figure 1, the force of the spring changes downward, which also has the effect of preventing loosening. Also, 7! l
Regardless of the +7!2 relationship, according to the present invention, the overall height is smaller than that using conventional helical springs, and the terminal connection device can be made smaller.
