本発明は、主としてビス締結部がドーナツ型をした端子
を接続する端子台の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to an improvement in a terminal block that connects terminals having doughnut-shaped screw fastening parts.
従来、＄２図に示す如き、端子を接続する端子台は、端
子台本体から該端子を取外すと、それに伴って端子締結
用のビスも端子台本俸から分離する構造となっていた。Conventionally, a terminal block to which a terminal is connected, as shown in Figure 2, has a structure in which when the terminal is removed from the terminal block body, the terminal fastening screw is also separated from the terminal block main body.
そのため、取外したビス及びワッシャを紛失する事が多

原因となる虞れがあった。さらに、端子を端子台本体に
再接続する際に、ビスをビス穴に整合する作業が迅速に
行えない欠点が存在した。特に、第２図のような元型の
端子は一つの発電プラント等に１０万個以上使用され、
定期的な絶縁試験等の際にそれが夫々取外されるもので
あるため、締結ビスの再取付に膨大な時間を要していた
。As a result, removed screws and washers are often lost, and there is also the risk of accidentally dropping them into the control panel, causing an accident. Furthermore, when reconnecting the terminal to the terminal block main body, there was a drawback that the work of aligning the screws with the screw holes could not be performed quickly. In particular, more than 100,000 prototype terminals like the one shown in Figure 2 are used in a single power plant, etc.
Since these screws are removed during periodic insulation tests, it takes an enormous amount of time to reinstall the fastening screws.
そこで、本発明は上記の問題点を解決した端子台を提供
する。Therefore, the present invention provides a terminal block that solves the above problems.

発明の端子台の各実施例につき説明する。In the terminal block of the present invention, one end of an elastic body 2 is fixed to a terminal block main body 1, and a screw 3 for terminal fastening is locked to the other end of the elastic body 2. The elastic body 2 is configured to be able to retain the screw 3 even when the screw 3 is removed from the screw hole 7 of the terminal block main body 1. Hereinafter, each embodiment of the terminal block of the present invention will be described based on the drawings.

ネ２と接続導体５との間に介装し、ビス３を締結する。FIG. 1 shows a first embodiment of this terminal block. In this terminal block, a flat connecting conductor 5 and an elastic body 2 made of a plate spring (hereinafter referred to as plate spring 2) are both inserted into a terminal block main body l. The leaf spring 2 is formed into an inverted trapezoidal shape, and screw holes are formed in the horizontal portions 6 provided at both ends thereof, and 81 screws 3 for terminal fastening are inserted into the screw holes. Further, as shown in the figure, a connecting conductor 5 is attached to the upper surface of the terminal block main body weight, and screw holes 7 are bored at both ends of the conductor at positions that align with the screw holes of the leaf spring 2. There is. Therefore, in order to attach the terminal 4 to the terminal block, first screw the screw 3 onto the leaf spring 2,
The tip of the screw 3 is provided to protrude very slightly from the back surface of the leaf spring 2. Next, the terminal 4 fitted at the tip of the electric wire 8 is interposed between the leaf spring 2 and the connecting conductor 5, and the screw 3 is fastened.

グワッシャを介装してもよい。At this time, the tip of the screw 3 screwed onto the leaf spring 2 is positioned in advance to align with the screw hole 7 of the terminal block main body 1, so the terminal 4 can be fastened to the terminal block extremely easily and quickly. . Note that the leaf spring 2 is formed in an inverted trapezoidal shape, and the screw 3
is biased in the direction away from the screw hole 3. Therefore, when the screw 3 is fastened, the leaf spring 2 acts as a spinning washer. Next, to remove the terminal 4 from the terminal block, loosen the screw 3. When the tip of the screw 3 comes off from the screw hole 7, the elastic force of the leaf spring 2 causes the end of the leaf spring 2 to separate from the surface of the terminal block main body l. At this time, the tip of the screw 3 is screwed into the leaf spring 2. Therefore, there is no risk of losing the screws 3, and the terminals 4 can be reconnected very easily and quickly. In addition to the above configuration, a spring washer may be further interposed between the leaf spring 2 and the screw head.

The diameter of the neck portion 9 of the screw 3 is formed to be smaller than the diameter of the threaded portion 1o. A long hole 11 is formed at the tip of the leaf spring 2, and its short diameter is made slightly larger than the outer diameter of the threaded portion of the screw 3. At the same time, when the leaf spring 2 moves from the solid line position to the chain line position as the screw 3 is fastened, the elongated hole 11
The elongated hole 11 is sized so that the inner surface of the hole does not come into contact with the screw 3.
Determine the major axis of. This prevents the screw 3 from loosening the terminal 4 on one side. Further, a fastener or an internally threaded washer 12 is attached to the neck s9 of the screw 3. The internal thread 13 of the washer 12 can be screwed onto the threaded portion 10 of the screw 3. Then, after loosely fitting the screw 3 into the long hole shell of the leaf spring 2, the washer 12
is screwed into the screw 3 up to its neck 9, and then the washer 12 is loosely fitted into the neck 9. Then, as shown in FIGS. 4 and 5, the cough washer 126 loosely fitted to the neck 9 prevents the leaf spring 2 from being removed. Next, FIG. 6 shows a third embodiment of this terminal board. The screw 3 of this embodiment is the same as that of the second embodiment, or one end of the temporary spring 2 is formed into a substantially U-shape. At the same time, the horizontal part 6 of the leaf spring end
An internal thread 13 into which the screw 3 is screwed is bored in the hole. Then, tighten screw 3 to its neck 9'! ! It is screwed in and loosely fitted in the neck part 9. Therefore, when the terminal is fastened to the terminal block using the screw 3 in such a state, the leaf spring 2 secured to the screw 3 is easily bent, and uneven tightening of the terminal due to the leaf spring 2 is prevented. .
本発明の端子台は以上のような構成からなり、次の効果
を有する。The terminal block of the present invention has the above configuration and has the following effects.
ビス３を端子台本体１のビス穴７がら取外して該本体１
から端子４を収外すと、ビス３は弾性体２の一端に係止
されるように構成している。Remove the screw 3 from the screw hole 7 of the terminal block body 1 and remove the screw 3 from the terminal block body 1.
When the terminal 4 is removed from the housing, the screw 3 is configured to be locked to one end of the elastic body 2.

At the same time, when reconnecting the terminal 4 to the terminal block main body l, since the screw 3 is secured in advance by the elastic body 2, there is no need to drop the screw 3, and the connection between the screw 3 and the screw hole etc. Since alignment is extremely easy, the screw can be fastened easily and quickly. Therefore, there is an effect that masking work after insulation testing of equipment or wiring can be quickly performed.
