Description

[Detailed description of the invention] This invention consists of a male block with a small number of terminals and a female block with a large number of terminals, and a plurality of male blocks are connected to one female block. By installing them in combination, you can see at a glance which male block is connected to which circuit, making maintenance and inspection easier, and you can add or remove male blocks as necessary.
Lean, i.e. one female block with a large number of compartments and with terminals in said large number of compartments, and a plurality of male blocks with a small number of compartments with terminals in said small number of compartments. The device is characterized in that the terminals of the female block and the terminals of the male block are detachably connected.

Conventionally, connector-type terminal blocks have been known that are made by combining male and female terminal blocks, but in both cases, the number of terminals on the female block and the number of terminals on the male block are the same, and it is difficult to determine which terminal goes to which circuit. It is not possible to recognize whether the block is connected, and the entire block must be removed and checked using a tester during maintenance or inspection, and it is not possible to add or reduce terminals, resulting in a lot of waste.

This idea eliminates these inconveniences,
Next, the structure of one specific example will be explained in detail. In this example of the invention, a small number of sections 4, 4, etc., such as 2 to 5 sections, are formed on the insulating base 5, and a plurality of male blocks M... are provided with male terminals 3 in each section 4. …
A large number of sections 9, 9, 9, . Moreover, the terminal 3 is formed by bending the conductive plate into the cylindrical part 1.
A and an insertion leg 2 are formed, a screw hole 1b is screwed into the upper surface 1a' of the cylindrical portion 1a, and a conductive push spring 1c bent into a substantially U-shape is placed on the upper surface 1a'. At the same time, the pressing part 1c' of the pressing spring 1c is inserted into the cylindrical hole 1a'', and the connecting screw 1d is screwed into the screw hole 1b through the insertion hole 1c'', while pushing the pressing part 1c' with the shaft end 1d'. A connecting portion 1 includes a shaped portion 1a, a push spring 1c, and a connecting screw 1d, and a terminal 8 is formed by bending a conductive plate to form an inserted portion 7 with a semicircular cross section and a leg-shaped connecting portion 6 facing each other. In addition, locking claws 11, 11 are integrally formed in the middle of the connection portion 6, and vertical holes 12 and horizontal holes 13 are communicated with each section 4 of the insulating base 5 by crossing them. with horizontal hole 13
A groove 14 is formed from below, and the cylindrical part 1a and the push spring 1c are accommodated in the horizontal hole 13.
4 and lock the lower end thereof to the outside of the insulating base 5, insert the connecting screw 1d into the vertical hole 12, press the pressing part 1c' with the shaft end 1d' with the above structure, and press the insulating base 5. A concave arch groove 15 is formed on one side of the 5, and a convex arch groove 16 that fits thereon is formed on the other side, and a convex arch groove 17 is formed on the back surface and in each section 4,
In addition, a vertical hole 18 is formed in each section 9 of the insulating base 10, and the inserted part 7 is buried in this vertical hole 18, and the leg-shaped connection part 6 is protruded outside the insulating base 10. The retaining claw 11 is locked to the bottom surface 10' of the base, and a planar U-shaped wall 19 is provided protruding around the flat surface of the insulating base 10. In addition to forming convex arched ridges 21, concave arch grooves 22 are formed on the back surface and in each section 9.

Next, how to use this example will be explained.

For example, one female block W has 10 sections, one male block M has two sections, one male block M has three sections, and one male block has 5 sections. One block M is prepared, each male block M is placed on the flat surface of the insulating base 10, and each insertion leg 2 is inserted into each insertion leg 7 to connect. At this time, each convex arc rim 16 fits into the concave arc groove 15 or 20, the convex arc ridge 21 fits into the first concave arc groove 15, and each convex arc ridge 17 fits into each concave arc groove 22. Therefore, each male block M can be reliably connected without making any mistake in its front, rear, left, or right arrangement. Then, connect the circuit or electric wire of the printed circuit board to each connection part 6, insert the electric wire into the cylindrical hole 1a'', screw the connection screw 1d, press the pressing part 1c', and press the pressing part 1c'.
C′ is used to connect the wires by pressing.

Therefore, if the five male blocks M on the far left are not needed, remove them and if necessary, install them.Also, if the middle male block M is connected to the power supply. , the male block M on the left
In a case where the male block M on the right is connected to the signal circuit and the male block M on the right is connected to the display circuit, for maintenance and inspection, first disconnect the middle male block M, then the current will flow into the device. It is immediately obvious that the circuit is not connected, and the tester can safely check other male blocks M.
This makes it easy to check whether there is any failure in the solder, etc.

Furthermore, by color-coding the male blocks M, it becomes clearer which male block is connected to which circuit.

Thus, since this invention has the above configuration,
Male blocks can be added, subtracted, or changed as needed, which is extremely rational.Moreover, it is possible to immediately recognize which circuit each male block is connected to, making maintenance extremely easy and safe.・It is something that can be inspected.
