[Industrial applications]

 The present invention relates to a relay terminal block for connecting lead wires, and more particularly to a relay terminal block suitable for use near a vibration source such as a drive motor of a Shinkansen or the like.

[0002]

[Prior art]

 Conventionally, as a relay terminal block, as shown in FIG. 7, a terminal block 51 formed of an insulating member and provided with a partition 50 and long in the lateral direction has been used. One terminal plate 52 made of a metal piece is provided in each partition 50, and mounting screws 53 are detachably provided on the upper surfaces of the terminal plates 52, and the tip of the lead wire is attached. The crimp terminal attached to is attached by screwing.

[0003]

[Problems to be solved by the device]

 However, the horizontal relay terminal block shown in FIG. 7 has a problem that it is impossible to install it in a narrow place because the length of the terminal block having many connecting parts becomes long. Further, in the double-row terminal block for relay shown in FIG. 8, although the length direction can be shortened, there is a problem in that the lead wires overlap each other, which is inconvenient in terms of maintenance. As shown in FIGS. 10 and 11, in the case of FIG. 9, a part of the lead wire 14 also overlaps, and in the type of FIG. 8 and FIG. There is a problem in that it is difficult to see the mounting screws 53, and it is difficult to process the connection on the lower side in a later step, and it is also difficult to find looseness of the mounting screws 53. Also, in any of the above-mentioned relay terminal blocks, another lead wire is connected to each terminal piece provided on the lower side by soldering, but the soldered lead wire is drooped and dangled as it is. Therefore, if it is placed in the vicinity of a vibration source of a vehicle or the like, there is also a problem that the soldered portion is peeled off due to aged use accompanied by vibration. As an anti-vibration measure, it has been attempted to fix the lead wire with an adhesive or a filling material, but it has the drawback that it cannot be repaired in terms of maintenance in addition to being complicated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a crimp terminal for each lead wire to each mounting screw in a multi-row multi-stage type relay terminal block. Even if they are connected again, they do not overlap with each other, the connection status can be easily confirmed from the outside, and the wiring and re-tightening on the lower side can be performed easily, and at the same time as the lead wire connection. It is easy to solder the terminal piece on the soldering side and provide a relay terminal block that does not cause connection failure due to cracks in the solder on the soldering side due to vibration. It is what

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the relay terminal block of the present invention is a relay terminal block 1 of an insulating member formed in multiple rows in a plurality of rows in the vertical direction, and has a terminal plate 3 on the upper side. The lower side provided has an empty seat portion 5, the upper side having the terminal plate 3 provided on the lower side has an empty seat portion 5, and the upper terminal plate 3 and the lower terminal plate 3 are arranged alternately, and the terminal plate 3 The conductive terminal piece 3A is made to project on the rear surface of the relay terminal block 1 and corresponds to the protruding position of the terminal piece 3A below these terminal pieces 3A, and another lead connected to the terminal piece 3A. A lead wire holding portion 11 for holding the wire 15 is provided, and the lead wire holding portion 11 is provided with a notch portion 12 into which another lead wire 15 is inserted.

[0006]

[Action]

 With the above structure, the relay terminal block 1 of the present invention has the lead wires 15 connected to the respective terminal plates 3 arranged without overlapping each other, so that the maintainability and workability are very good. The terminal piece 3A protrudingly provided on the rear surface of the relay terminal block 1 is inserted into the insertion hole 10 of the lead wire holding portion 11 or introduced into the insertion hole 10 through the notch 12 and held therein. Since the tip of the wire 15 can be locked, the soldering work is easy, and because it is held by the lead wire holding portion 11, the problem of solder peeling against vibration is prevented, and maintenance is also possible. Will be easier.

The terminal board housing portions 4 are housed on every other side with the positions thereof shifted so as to enclose the child board 3 on three sides. The adjacent portions of the terminal plate accommodating portions 4 provided every other one have an upper portion 2A or a lower portion 2B as a vacant seat portion 5 protruding in the original shape. A step portion 6 extending to a predetermined height is provided at each diagonal corner of the base 2, and a screw hole 7 for fixing the base 2 is formed in the step portion 6. It is set up. The terminal board 3 housed in the terminal board housing 4 is a conductive metal member housed substantially in the terminal board housing 4, and has an attachment at the center for screwing a crimp terminal 13 described later. A screw 8 is provided.

A terminal piece 3A as shown in FIG. 2 is inserted into the terminal plate 3 through the inside of the base 2 so as to project on the rear surface side of the base 2, and the mounting position of the terminal piece 3A is the upper stage. The terminal piece 3A of the lower step portion 2B is aligned upward with the terminal plate 3 of the portion 2A and is arranged in a horizontal row. A small hole 9 is provided on the tip side of each of the terminal pieces 3A for locking and soldering a core wire of a lead wire 15 described later. Below the base 2 on which the terminal piece 3A is projected, a lead wire holding portion 11 having an insertion hole 10 through which the lead wire 15 is inserted is provided just below the small hole 9 of the terminal piece 3A. It is projected like a plate. The lead wire holding portion 11 is provided so as to project slightly longer than the distance between the tip of the terminal piece 3A and the back side surface of the base 2. The inside of the lead wire holding portion 11 is between the rear end surface and the insertion hole 10. The notch 12 which is the insertion hole 10 is provided, and the lead wire 15 can be held in the insertion hole 10 through the notch 12.

Further, as shown in FIG. 4, the terminal piece 3A provided on the rear surface side of the relay terminal block 1 covers the tip of another lead wire 15 held in the insertion hole 10 of the lead wire holding portion 11. Since the core wire 16 can be peeled off and the core wire 16 can be inserted and held in the small hole 9 of the terminal piece 3A, the soldering work is facilitated, and the soldered lead wire 15 is securely held in the soldering portion and the lead wire holding portion 11. Therefore, even if the relay terminal block 1 is mounted near the vibration source, cracking or peeling does not occur in the soldered portion, and defective connection can be completely prevented. Further, since the lead wire holding portion 11 is provided with the notch 12 that substantially faces the insertion hole 10, even if the lead wire 15 is press-fitted from the notch 12, the lead wire 15 can be easily mounted in the insertion hole 10. it can.
