Description

[Detailed Description of the Invention] The present invention relates to a terminal board that can be set to have an arbitrary number of terminals and an arbitrary terminal spacing.

2. Description of the Related Art When mounting various parts on electronic equipment or wiring between circuits, terminals of the electronic equipment are often connected using terminal boards. Conventionally, such a terminal board is shown in FIG. 1. That is, a required number of terminals 2 are fixed to the substrate 1 by caulking 3 along opposite edges of a substrate 1 made of an electrically insulating material of a predetermined size so that the terminals do not rotate after installation. It was attached to a mounting surface 4 of a chassis, an equipment rack, etc. with screws 6 via a spacing member 5. For this reason, it is necessary to caulk the terminals and also to use a spacing member, and furthermore, it is inconvenient both in terms of time and economy as the terminal board must be manufactured according to the desired number of terminals, the distance between the terminals, etc. Furthermore, even if the board is cut parallel to one row of terminals and the board is molded to have a single row of terminals, a large number of terminal boards must be prepared according to the number of singletons, as described above. There are similar inconveniences.

The purpose of the present invention is to solve the above-mentioned conventional disadvantages and provide a terminal board that can easily have a desired terminal configuration.For this purpose, the present invention has a mounting surface and one side of the mounting surface in the longitudinal direction. an integrally molded part having parallel eave-like protruding edges on the upper surface separated from the mounting surface; a terminal row arranged in the length direction of the eave-like protruding edges; and a predetermined number of two or more terminals. A notch-like recess that can be divided into a plurality of parts and connected at a part of the mounting surface side, and one or two recesses for mounting provided in the length direction of the mounting surface between the divisible recesses. Embodiments of the present invention will be described below with reference to the drawings. Note that the same parts as in FIG. 1 are denoted by the same reference numerals.

FIG. 2 is a perspective view showing an embodiment of the present invention, in which they are attached as a pair to the main parts. The board part 7 of the terminal board has a main body part 71, an eave-like protruding edge part 72 on the upper surface, a notch 73 at a predetermined length, and a mounting hole 74 penetrating the main body within the predetermined length unit. It is integrally formed of an insulating material such as thermosetting resin. The main body portion 71 has a substantially rectangular cross-sectional shape, and a projecting edge portion 72 is formed on the upper surface of the main body portion 71 so as to coincide with the upper surface thereof. At the time of integral molding, at least two terminals 2 are molded and disposed within the predetermined length unit of the projecting edge portion 72. For example, this terminal 2 has a protruding shape with a part corresponding to a conventional caulking hole, and by inserting this part or inserting a part or all of the end part, molding and fixing it, a row of terminals can be formed on a terminal board all at once. Can be configured. The notch 73 is a wedge-shaped recess that is easily formed by molding in the direction of the mounting surface on the lower surface of the terminal board body 71, including the upper surface and the protruding edge portion 72, and is formed so as to be connected at a part of the bottom surface. . Also, the mounting hole 74
is a hole into which a mounting screw can be sunk. The terminal plate formed in this way has a minimum length unit 75, 7 defined by the cut 73.
6, . . . 7n are formed into a predetermined length, and two mounting holes 74 are provided in the length unit as shown in the figure.

In order to attach the terminal plate having the above structure to the main part 4 of a chassis or a device, it is divided by bending and folding (or cutting with an appropriate tool) the notches 73 at the positions where the desired number of terminals are obtained. Align a pair of terminal board units obtained in this way, and screw the pair of terminal boards into the screw holes that are opened at a required interval and face each other in alignment with the terminal board mounting holes 74 of the mounting section 4. 6 into the mounting hole of the terminal board and screw it in place. In this case, the screw holes and screws 6 are not required to correspond to all the holes for attaching the terminal board, but may be provided at appropriate locations. However, in the case of minimum unit length, it must be attached in two places. As described above, a terminal plate section is formed that has a desired number of terminals arranged in parallel at a required facing interval, and the above interval can be set arbitrarily, and the number of terminals can also be combined in multiple units with an arbitrary number as the minimum unit length. It can be selected and set.

The present invention is not limited to the above, and the minimum unit length may be one mounting hole. In this case, when multiple sets of lengths are used, it is stabilized because it is mounted with at least two mounting screws. However, in the case of the minimum unit length, it is also possible to form a positioning locking portion on the mounting surface of the terminal plate so that the terminal plate does not rotate, or to attach it using a portion that functions in this way. In addition, if the inside of the main body part 71 is not made to have a solid structure and the outside of the main part is suitably hollowed out or deformed, it is possible to reduce the amount of resin material, reduce the weight, and prevent deformation during molding. For this reason, as shown in FIG. 3, an O-shaped substrate portion 7' may be used.
In this substrate portion 7', there is no need to make the mounting screw holes sunken, and the amount of resin material can be reduced significantly.

As described above, the present invention can easily form a terminal board configuration with any number of terminals and any opposing spacing, and does not require any spacing member to be interposed between the mounting surface and the long board during installation. Because it is only necessary to prepare terminal boards, the number of parts is reduced, assembly is easier, and costs are lower, compared to conventional methods in which the required terminal boards are manufactured. Note that the description is not limited to the embodiments, and the shape of the notch in the terminal board, the fixed part of the terminal board, and the shape of the terminal may be applied in any other way, such as providing independent notches for plate terminals, pin terminals, and insulation between terminals. Needless to say, the arrangement of the terminal boards can be freely set, such as mounting them in a single row or in double rows of two or more facing each other.
