Description

[Detailed Description of the Invention] (a) Technical Field The present invention relates to a terminal block integrally formed with a plurality of relay terminals each of which is biased by a spring in a direction in which a terminal plate and a terminal washer are separated.

(b) Prior art When connecting a lead wire to a relay terminal, the lead wire is inserted between the terminal plate and the terminal washer, and the connection is made by tightening the screw, but in general, even if the screw is loosened, the terminal washer remains attached to the terminal plate. It remains in close contact,
This method had the disadvantage that it required a separate step to lift the terminal washer in order to insert the lead wire, which required extra man-hours for wiring work.

In addition, a terminal block with a structure in which the terminal washer is pushed up by a spring has been proposed, but one
Even when two springs are required for one terminal plate, or two terminal washers are biased by one spring, leaf springs, linear springs, scissor-shaped springs, etc. are used. Because of this, the local deformation of the spring material is large, making it easy to break and making the structure complicated.
The drawback was that it was difficult to assemble and increased costs.

(c) Purpose The present invention was made in view of the above circumstances, and the purpose is to provide a terminal block that is easy to assemble and durable.

(D) Structure The present invention integrates a plurality of relay terminals each consisting of a terminal plate with two screw holes and two guide holes, a terminal washer in which the guide part and the washer part are formed in an L shape. This terminal block is constructed so that a terminal washer is pushed up by a coil spring interposed between an operating rod bridged at the tip of a guide portion and a back plate.

(E) Embodiment FIG. 1 is a perspective view showing the outer shape of a terminal block according to the present invention, in which two screw holes 11 and two guide holes 12 are bored in a short fence-shaped terminal plate 10. A terminal washer 20 having an L-shaped guide portion 22 and a washer portion 21 slidably inserted into the guide hole is screwed onto the terminal plate 10 with a screw 30. Three terminals 40 are integrally assembled by a terminal block main body 50.

Inside the terminal block body 50, an operating rod (not shown), a coil spring, and a back plate, which will be described later, are built-in, and the gap between the terminal plate 10 and the washer part 21 is the same as the screw 30.
It is held as shown in the figure depending on how it is screwed in.

FIG. 2 is a sectional view showing the internal structure of the terminal block main body. In addition to the above-mentioned parts, 23 is a recess cut into the tip of the guide part 22, and 60 is a recess 23 of each of the two terminal washers. A T-shaped operating rod 70 is a U-shaped back plate with a flange in cross section, and a coil spring 80 is held and pressed between the operating rod 60 and the flange portion 71 is connected to the terminal block. Projections 51 and 52 near the bottom of the center of the main body 50
By horizontally mounting the washer part 21 on the lower surface of the head of the screw 30, the washer part 21 is urged.

Therefore, the washer portion 21 moves up and down together with the head of the screw depending on how the screw 30 is screwed in.

(f) Effects As mentioned above, in this invention, the terminal washer is in close contact with the head of the screw and moves up and down, so when connecting the lead wire to the relay terminal, the operation is easy and the number of man-hours for wiring work can be reduced, and coil springs are used. Insert the guide rod into the guide hole, turn the terminal block body over, insert the operating rod, coil spring, and back plate in sequence, and insert the flange of the back plate into the protruding part of the terminal block body. Assembling is completed by horizontally mounting the assembly, which simplifies the assembly process and reduces costs.

Claims (1)

[Scope of utility model registration request] A relay consisting of a short rail-shaped terminal plate with two screw holes and two guide holes, and two terminal washers with a guide part and a washer part formed in an L-shape. A terminal block in which a plurality of terminals are integrally formed in a terminal block main body, wherein the guide part is slidably inserted into the guide hole and a hole is bored approximately at the center of the washer part. A screw inserted into the screw hole is screwed into the screw hole, and one end of the coil spring is brought into contact with the approximate center of the operating rod that is bridged between the recesses cut at the tips of the two guide parts. , by pressing the other end with a back plate having a U-shaped cross section with a flange and horizontally suspending the flange portion of the back plate over two protrusions formed near the bottom of the terminal block main body. A terminal block characterized in that the washer is biased in a direction away from the terminal plate.
