Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a terminal device, and relates to a terminal device that connects two terminals of electrical equipment, parts, etc.

[Technical background of the invention and its problems]

Conventionally, when connecting two terminals of electrical equipment or parts, for example, when connecting a ballast and a terminal block, as shown in Figure 1, terminal pieces 2 and 3 provided on the ballast 1 and the terminal block are connected. Connect the terminal pieces 5 and 6 of 4 to the electric wire 7,
8, the connection work had to be fixed at two places, which had the disadvantage of poor connection workability.

Also, there is a known terminal in which the terminal pieces 2, 3, 5, 6 are formed with a press-fitting groove 9 into which the electric wires are press-fitted, and the electric wires 7, 8 can be press-fitted therein. In order to connect between 5 and 6 and further branch and connect the electric wire 10 from the connection point, it is necessary to form two press-contact grooves 9 and 9a on one terminal piece 3, and the width of the terminal piece 3 This has the disadvantage that the connecting portion is large and the cost is high.

Furthermore, in order to automate the wiring work of connecting terminal pieces 2, 3, 5, and 6 using electric wires 7 and 8,

The width l ₁ of this fitting hole 25 is slightly wider than the thickness of the wire connecting piece portion 12 of the first terminal piece 11, and the length _l2 is the press-fit edge of the wire connecting piece portion 12 of the first terminal piece 11. 1
It is formed slightly narrower than the length l ₃ between 4 and 4.

When the wire connecting piece 12 of the first terminal piece 11 is inserted into the insertion hole 25 of the second terminal piece 19 from below, it is guided by the insertion guide edges 13 on both edges of the tip end side of the electric wire connecting piece 12 and is inserted. A press-fitting edge 14 continuous with this fitting guide edge 13 is press-fitted into both sides of the fitting hole 25. At this time, the press-fit edge 14 of the wire connection piece 12 is inserted into the wire connection piece 1 from the inner end of the wire pressure welding groove 15.

Next, the case of connecting the ballast 27 and the terminal block 28 using this terminal device will be explained with reference to FIG. 4.

A ballast 27 and a terminal block 28 are disposed adjacent to a ballast base 30 fixed to a fixture body 29 such as a lighting fixture. In this ballast 27, the first terminal piece 11 is provided to protrude from a terminal block portion 31 integrally formed to protrude from the coil bobbin, the second terminal piece 19 is attached to the terminal block 28, and the base After fixing the stabilizer 27 to the terminal block 30, the wire connecting piece 12 of the first terminal piece 11 is fitted into the fitting hole 25 of the second terminal piece 19 of the terminal block 28, so that both terminal pieces 1

Elastic projecting pieces 33 are formed on both sides of the insertion hole 25 of the second terminal piece 19 by cutting and raising the wire connecting piece portion 12 of the first terminal piece 11 in an inclined shape in the insertion direction.

In this structure, when the wire connecting piece 12 of the first terminal piece 11 is inserted into the fitting hole 25 of the second terminal piece 19, a small pressing force is required due to the spring action of the elastic protrusion 33 that contacts the press-fit edge 14. As the electric wire connecting piece 12 is fitted, the connection and fixation are ensured, and the elastic projection 33 bites into the press-fit edge 14 against external force in the direction of coming off, making it difficult to come off.

In the above embodiment, the connection between the ballast and the terminal block has been described, but the present invention can also be applied to the connection of various electrical devices, parts, and the like.

〔Effect of the invention〕

According to the present invention, the wire connecting piece portion of the first terminal piece in which the wire pressure contact groove is formed is fitted and fixed into the insertion hole of the second terminal piece, and the electric wire in which the wire pressure contact groove is formed in the second terminal piece is fixed. Since the connection piece part is separated from the wire pressure contact groove of the first terminal piece, the connection between each terminal piece of equipment, parts, etc. is made by connecting the wire connection piece part of the first terminal piece to the wire pressure contact groove of the second terminal piece. It can be easily connected by simply fitting it into the insertion hole, and there is no need to use electric wires, improving connection work efficiency and making it possible to automate the connection work.Also, since the wire connection pieces of both terminal pieces are spaced apart and facing each other,
Furthermore, when pulling out an electric wire from the connection point of both terminal pieces, the electric wire can be connected by press-fitting the electric wire into the pressure welding groove of both electric wire connecting pieces, and both electric wire connecting pieces are close to each other. Therefore, the wire can be connected in one operation to the press-contact grooves of both wire connection pieces, and since the wires are connected between both terminal pieces, the wires are connected in a double manner and the reliability of the connection is improved.

In addition, by forming elastic protrusions on both sides of the insertion hole of the second terminal piece that press into contact with both sides of the wire connection piece part of the first terminal piece, elastic protrusions are formed when the wire connection piece part of the first terminal piece is inserted. The spring force of the protruding piece acts, the fitting is carried out easily, the pushing force for fitting can be reduced, and the contact reliability between both terminal pieces can be improved, and the connection between both terminal pieces can be fixed.

In addition, the width of the wire connecting piece of the first terminal piece is gradually narrowed toward the distal end, and both sides near the bent base end are formed with parallel press-fit edges, making it easy to insert the wire connecting piece. Since the connection and fixation is performed using parallel press-fit edges, the contact pressure is constant and the connection and fixation are stable even if the insertion depth of the wire connection piece portions is slightly different.
