Description

[Detailed Description of the Invention] This invention relates to a terminal block for incandescent lamp sockets and the like.

Conventionally, a terminal block for a power connection part of an incandescent lamp socket has a plurality of terminal members for connecting Faston terminals arranged side by side with nothing interposed between them and protruding from a terminal block body. Therefore, in order to obtain an insulating distance, it was necessary to leave a large distance between the terminal members, and it was not possible to obtain a gap in which a finger could be inserted between the socket cylinder on the outer periphery and the terminal member. Therefore, when inserting the Faston terminal, there was a problem that it was difficult to insert a finger because it was difficult to insert the terminal.

Therefore, the configurations shown in FIGS. 1 and 2 have been attempted.

This terminal structure has a terminal separation wall 2 that partitions the socket cylinder 1, which is the terminal block main body, into two vertically divided spaces.
and a faston which is fixed to the terminal mounting part 3 integrally formed on the terminal separation wall 2 and connected to the power supply side cord 4 with one end thereof facing the power supply side opening of the socket cylinder 1 along the terminal separation wall 2. The terminal member 7 has a contact claw portion 6 into which the terminal 5 is fitted.

The terminal member 7 has a caulking claw piece 8 on the horizontal surface that comes into contact with the terminal attachment part 3, and the nail piece 8 is caulked and fixed in the caulking hole 3a of the terminal attachment part 3, and the other end is fixed. The portion extends to the incandescent lamp screwing side of the socket cylinder 1 so as to come into contact with the incandescent lamp cap.

According to this configuration, since the pair of terminal members 7 are opposed to each other via the terminal separation wall 2, insulation is reliable, and the distance between these terminal members 7 can be shortened. You can secure space for your fingers. Therefore, Faston terminal 5
The insertion work efficiency is improved. In addition, the clinching claw piece 8
Therefore, the terminal member 7 can be attached more easily than, for example, when it is attached by integral molding or screwing.

However, in such a configuration, a gap G for faston terminal insertion is provided between the contact claw portion 6 and the terminal separation wall 2 opposing thereto, and the contact claw portion 6
has a structure in which it is supported only at the lower end, and is attached only by the caulking claw piece 8. Therefore, a backlash occurs in which the caulked portion is used as a fulcrum and tilts in the front-rear direction (indicated by arrow symbols A and B), and also a backlash occurs in the axial direction.

Furthermore, since the contact claw portion 6 has a width smaller than that of the Faston terminal 5, it has the disadvantage that it is difficult to fit the Faston terminal 5 in an optimal position.

Therefore, the purpose of this invention is to provide a terminal block that allows Faston terminals to be fitted in optimal positions without wobbling, is easy to perform the fitting operation, and is easy to manufacture. .

An embodiment of this invention is shown in FIGS. 3 to 5. That is, in this terminal block, one end of the terminal member 7' in the conventional example along the terminal separation wall 2' is branched into three pieces by two vertical notches 9, and a central projecting piece is formed. A Faston terminal fitting piece 6' into which the Faston terminal 5 is directly fitted,
The left and right projecting pieces are used as attachment pieces 10, 10 for fixing the terminal separation wall 2' in contact with the terminal separation wall 2'. The surface of the terminal separation wall 2' to which the mounting pieces 10, 10 are fixed is formed to protrude by a predetermined thickness toward the front from the surface where the Faston terminal fitting pieces 6' and the vertical notches 9, 9 face. Thus, a gap G' that allows insertion of the Faston terminal 5 is secured between the Faston terminal fitting piece 6' and the terminal separation wall 2'.
Faston terminal fitting piece 6' and mounting pieces 10, 10
and have approximately the same length.

The mounting pieces 10, 10 are supported by a support surface 2'a protruding from the terminal separation wall 2' to prevent the mounting pieces 10 from moving laterally.

The other configurations are the same as the conventional example,
8' is a caulking claw piece, 3' is a terminal mounting portion, and 3'a is a caulking hole.

According to this configuration, as in the proposed example shown in FIG. 2, since the terminal member 7' is attached with the caulking claw flat 8', the attachment of the terminal member 7' is easier and manufacturing is easier than with integral molding or screw fixing. .

In addition, one end of the terminal member 7' along the terminal separation wall 2' is not only supported at the lower end where it is bent from the other part of the terminal member, but also supported by the mounting pieces 10, 10 on both sides of the terminal separation wall. 2', its mounting strength is improved, and wobbling in the front-rear direction and width direction can be prevented.

In particular, back-and-forth wobbling, that is, tilting with the caulked portion as the fulcrum, can be avoided at a position far from the tilting fulcrum because the mounting pieces 10, 10 have approximately the same length as the Faston terminal fitting piece 6'. This allows for reliable rattling prevention.

Further, the connection between the Faston terminal fitting piece 6', into which the Faston terminal is directly fitted, and the mounting pieces 10, 10 are separated by vertical notches 9, 9, and when the Faston terminal is fitted, this vertical The notches 9 act as guide grooves for inserting the Faston terminal, and the Faston terminal can be fitted into the Faston terminal fitting piece 6' in an optimal stable position. In this case, the Faston terminal fitting piece 6' and the mounting pieces 10, 1
0 are substantially the same length, so the guiding effect is higher than, for example, when the mounting pieces 10, 10 are made shorter.

The mounting piece 1 of the terminal separation wall 2'
The support surface 2'a on which the terminal separation wall 2' and the Faston 10 are supported is made to protrude forward by a predetermined thickness from the area facing the Faston terminal fitting piece 6′ and the vertical notches 9, 9, and Since the gap G' that allows insertion of the Faston terminal is secured between the terminal fitting piece 6' and the terminal fitting piece 6', the terminal connection can be carried out smoothly.

Further, at the same time as the above-mentioned proposed example, since the pair of terminal members 7' are opposed to each other via the terminal separation wall 2', the distance between both terminal parts 7' can be shortened, and the outer side of both terminal members 7' can be shortened. You can secure space for your fingers to enter.
The ease of inserting the Faston terminal 5 is improved. Note that the mounting pieces 10, 10 are attached to the terminal separation wall 2'.
Since the support surface 2'a is provided protrudingly,
Shaking in the width direction can be reliably prevented.

The mounting pieces 10, 10 may be supported on the support surface 2'a by simple contact, or by using an adhesive or a fastener such as a screw. Various configurations can be adopted, such as by setting the terminal 10 in a tilted state in advance toward the terminal separating wall 2' and pressing it elastically against the terminal separating wall 2'.

As described above, the terminal block of this invention includes a terminal block main body having a terminal separation wall and a terminal mounting part protruding from the lower end thereof to both sides, and a caulking hole penetrating above and below the terminal mounting part; a pair of terminal members having lower portions of caulking claw pieces disposed on both sides of the terminal separation wall and inserted into the caulking holes and fixed by caulking; The Faston terminal fitting piece and the mounting piece are branched into a pair of right and left mounting pieces, and the Faston terminal fitting piece and the mounting piece are formed to have approximately the same length. Since it is provided protruding from the terminal separation wall, it has the following effects.

That is, since the terminal member is caulked and fixed with the caulking claw piece, the terminal member can be easily attached and manufactured. In addition, the two vertical notches branch out into a central Faston terminal fitting piece and a pair of left and right mounting pieces, and the mounting pieces are formed to be as long as the Faston terminal fitting pieces.
While employing the simple mounting structure by caulking, the elongated mounting piece is supported by the support surface of the terminal separation wall, thereby ensuring secure prevention of rattling. Furthermore, the Faston terminal can be fitted in a stable and optimal position. Further, since the Faston terminal fitting piece and the left and right mounting pieces are approximately the same length, it is easy to insert the Faston terminal. Furthermore, since the pair of terminal members are placed opposite to each other with a terminal separation wall in between, there is no problem with insulation and the distance between the two terminal members can be shortened, so there is no space for fingers to fit outside of both terminal members. This has the advantage of increasing the ease of inserting the Faston terminal.
