Description

[Detailed Description of the Invention] [Industrial Field of Application] The wire connection structure of the present invention relates to a wire connection structure used in electronic computers, electronic exchanges, other electronic devices, home appliances, and the like.

[Conventional technology]

Conventionally, this type of wire connection structure uses crimp terminals 12, as shown in FIGS. 3 and 4, and the input side 1
Connect the output wire 15 to the crimp terminal 12 from the direction of the input wire 14 and the output side 17 from the direction of the wire 14,
15's skin was stripped off and the core wire was crimped using a crimping tool. Then, it was fixed to the terminal block 13 by tightening each set screw 16.

[Problems to be solved]

The conventional electric wire connection structure described above has the disadvantage that the crimp terminals 14 and 15 are crimped to the core wire of the electric wire, which requires a lot of skill and a crimping tool. If you want to accommodate electric wires, connect the crimp terminals 12 to 2 as shown in Figure 4.
The disadvantage is that each screw must be tightened at the same time, which makes construction difficult and there is a high risk of damaging the partition piece 16.

[Means for solving problems]

The present invention has been developed by focusing on the above-mentioned conventional problems.Crimping work does not require skill or special tools, is simple and easy to operate in the factory, and eliminates the risk of component damage. The purpose is to provide a wire connection structure.

To this end, the present invention forms a fixing hole approximately in the center of a rectangular conductive flat plate, and on both sides of the fixing hole in the longitudinal direction, presser pieces are cut into the flat plate and bent into a semicircle. a connecting plate body having a through hole for inserting the tip at a position corresponding to the tip of the flat plate and a through hole for positioning on both sides in the longitudinal direction of the plane plate, and having approximately the same size as the connecting plate body; A pressure contact plate for pressure contact of the connecting plate, which has a stop hole formed in the center and has a notch at the tip for holding the electric wire and an engagement piece that fits into the positioning through hole on both sides. This provides a wire connection structure.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows a perspective view of the main body 1 and the pressure contact plate 6 of the wire connection structure of the present invention, and FIG. 2 is a perspective view showing an embodiment of the wire connection structure shown in FIG. This electric wire connection structure is composed of a connection plate main body 1 and a pressure welding plate 6, which form a rectangular flat plate.The connection plate main body 1 has a presser piece 2 on both sides that can press the first and second electric wires 10 and 11. It is set up. That is, in a connection structure for connecting electric wires, a fixing hole 8 is formed approximately in the center of a conductive flat plate of the connecting plate main body 1, and the flat plate is cut on both sides in the longitudinal direction of the fixing hole 8 to form a semicircular holding piece 2. First and second through-holes into which the presser pieces 2 are inserted are provided at positions corresponding to the tips of the presser plate 2, and through-holes for positioning are formed on both sides of the flat plate.
The pressure contact plate 6 for pressure contacting the connection plate main body 1 has approximately the same size as the connection plate main body 1, and has a stopper hole 8 in the center and a vertically curved engagement piece 7 on both sides of which has a triangular tip. It has a notch 7a cut out, and has a structure in which the engaging piece 7 is fitted into the through hole.

Therefore, in the wire connection structure of the present invention, as shown in FIG. Insert it into piece 2. Second
The electric wire 11 is also made in the same manner as the first electric wire. Next, press contact plate 6
By sandwiching and pressing the engaging piece 7 from above the first and second electric wires, screw the set screw 9 into the set hole 8 of the connecting plate body 1 and the screw hole of the block 20, and tighten the screws. , the holding piece 2 is the first and second electric wire 1
0 and 11 are pressed together and electrically connected.

[Effect of idea]

As explained above, the present invention forms a stopper hole approximately in the center of a rectangular conductive flat plate, and provides presser pieces cut into the flat plate and bent into a semicircle on both sides of the stopper hole in the longitudinal direction. A connecting plate body having a through hole for inserting the tip at a position corresponding to the tip of the holding piece and a through hole for positioning on both sides of the plane plate in the longitudinal direction, and a connecting plate body having approximately the same size as the connecting plate body. and a pressure welding plate for pressure welding the connecting plate, which has a stop hole in the center and a notch for holding the electric wire at the tip on both sides, and an engaging piece that fits into the positioning through hole. Because of the wire connection structure, the holding piece of the connection plate body is pressed into contact with the pressure contact plate, and when the engagement piece of the pressure contact plate fits into the through hole of the connection plate body, the electric wire is held in between. ,Firstly, there is no need to use crimp terminals to make crimped connections, which reduces crimping work.Secondly, since crimping work is not required, crimping tools are not required.Thirdly, input and output can be done as before. This has the advantage of not requiring a large terminal block on the side.
