Description

[Detailed description of the invention] This invention relates to a connector-type terminal block, and in particular, it is possible to insert and connect electric wires from the same direction as the attachment and detachment direction of the female and male bases, so the female and male bases can be connected. When pulling out the wire, there is no stress on the wire, there is no risk of it being cut, and the screw threading allows for easy and reliable connection work.In other words, the male and female bases W and M can be attached and detached from the top and bottom. In the terminal device of the connector type terminal block that can be freely connected,
The conductive plate is bent into a U-shape to form a bottom plate 8, an outer plate 7,
A space 4 is formed into which the electric wire 3 is inserted from the inner plate 11 and above, the upper end of the inner plate 11 is bent outward and horizontally to form a horizontal plate 14, a screw hole 15 is screwed into the horizontal plate 14, and a screw hole 15 is screwed into the horizontal plate 14. A screw 1 with a tapered shaft end is screwed into the hole 15 from above, and the connector part 10, which can be connected to and removed from the mating connector part 20 in the vertical direction, is connected downward from the bottom plate 8, and the cavity 12 is inserted into the inner plate 11. 13 are formed on top and bottom, and the conductive plate is bent into an F-shape to form the exclusion slanted edge 5 and the pressing part 6, and the upper end edge of the exclusion slanted edge 5 is bent to form the hook part 17. While hanging on the inner plate 11, the exclusion bevel 5 is attached to the upper cavity 12.
It is characterized by inserting the pressing part 6 into the space 13 so that the lower part of the exclusion bevel 5 faces the bottom of the screw hole 15, and inserting the pressing part 6 into the lower cavity 13 so that the end of the pressing part 6 faces into the space 4. be.

Recently, so-called connector-type terminal blocks that connect female and male bases have been known, but all of them have a connecting portion with an electric wire on one or both of the female and male bases. Moreover, the wire is female
It is guided from the direction perpendicular to the direction of attachment and detachment of the male base, wrapped around the screw, and tightened. For this reason, if you pull out the female and male bases after wiring, the wires may be strained and may break, and since many wires are bundled together, the wires become quite heavy, so it is difficult to pull out one base. It is extremely difficult. For this reason, it is desirable to connect the wires from the same direction as the attachment and detachment direction of the female and male bases.
To do this, screw in the connection screw from the side of the base,
You will have to lead the wires from above and wrap them around this. In other words, since the female and male bases are normally installed and removed in the up-and-down direction, the connection screws have to be screwed in from the side. However, since a large number of terminal blocks of this type are generally installed in parallel with each other with small gaps between them, it is not possible to thread the terminal blocks by attaching the connection screws to the sides.

This idea eliminates these inconveniences,
Next, to explain the structure of one specific example in detail, a conductive plate is bent to form a space 4 having an opening 4' above, and an outer plate 7 surrounding the space 4 is formed into a planar arc shape, and both sides are bent. Sawteeth 7', 7' are formed on the edges, a substantially L-shaped plate 9 is continuously provided below one edge of the bottom plate 8, and this substantially L-shaped plate 9 is further bent vertically to form a bifurcated clamping spring. A connector part 10 is formed, and the connector part 10 is positioned below the center of the bottom plate 8, and void parts 12 and 13 consisting of two-step notch grooves are provided in the inner plate 11 surrounding the space 4, and the upper end of the inner plate 11 is formed. is bent into an L-shape to form an outer plate 14' of the horizontal plate 14, a screw hole 15 is screwed into the horizontal plate 14, and the space below the screw hole 15 is used as a path 2 for the screw 1 for connection. Saw teeth 7'', 7'' are formed on both side edges of the plate 14', and on the other hand, the conductive plate is bent into a cross-sectional shape of "F" as the press fitting 16, and the upper beveled edge is removed and the beveled edge 5 and the lower beveled edge are formed. The upper end edge of the exclusion bevel 5 is bent outward to form a hook part 17, and the lower end edge of the lower bevel edge is bent obliquely upward to form a pressing piece 6', and the exclusion bevel 5 is formed into a gap. 12, and insert the pressing part 6 into the cavity 13 through the respective side openings 12' and 13',
The lower part of the exclusion bevel 5 and the upper part of the pressing part 6 are made to face the advancing/retreating path 2 of the screw 1, the hook part 17 is hooked to the upper inner surface of the inner plate 11, and the lower part of the pressing part 6 and the pressing piece 6' are The terminal device of the present invention is formed by facing into the space 4.

In addition, a large number of through holes 19, 19,

0, and then hit the device of the present invention from above to stick the saw teeth 7', 7', 7'', 7'' into the hole surface of the through hole 19, embed and fix the device of the present invention, and insert the shaft into the screw hole 15. A headless screw 1 with a conical end is screwed in to form a female base W. Further, in the figure, M is a male-type insulating base, and a plug-in piece is built in as a mating connector part 20 of each connector part 10, and the connector part 20 is bent at a right angle, and the side surface of the base M is Insert pin 2 into the printed circuit board P.
1, 21, 21... are made to stand out.

In this specific example, the device of the present invention is integrated with the clamping spring-shaped connector section 10 and installed on the female base W, but by integrating with the plug-like connector section, it can be attached to the male base M. Of course, it may be provided.

Next, to explain how to use this specific example, insert the electric wire 3 from above each space 4, and insert the screw 1 into the screw hole 1.
Continue screwing further into 5. Here, since the shaft end of the screw 1 is formed into a conical shape, it comes into contact with the exclusion bevel 5 facing into the advance/retreat path 2, and the exclusion bevel 5 is gradually removed from the advance/retreat path 2. It is pushed to the position shown by the chain line in FIG.
The end portion is pressed against the inner surface of the outer plate 7.

Therefore, even if it is necessary to pull out the female base W from the male base M after wiring as shown by the arrow in FIG.
It is sufficient to simply pull the female base W upwards without bending or cutting a large number of electric wires 3.

Since this invention has the above-mentioned configuration, the female and male bases can be attached and detached extremely easily without damaging or cutting the electric wires when attached to the base, and the attachment and detachment directions can be changed. By simply screwing a screw from above on the upper and lower bases, you can easily and quickly connect parallel electric wires from the same direction, and even when many terminal blocks are installed side by side on various devices, the screws can be tightened easily. It is extremely practical and has no trouble in operation.
