Abstract

(57) [Abstract] [Purpose] Absorb assembly tolerances and eliminate connection failures. [Structure] One of the mounting holes 1a provided in the terminal body 1 has a round hole shape, and the size of the position of the terminal from other objects is determined by the mounting hole 1a. Further, by making the other mounting hole 1b into a long hole shape, the difference in mounting accuracy is absorbed and connection failure is eliminated.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a power supply terminal used for supplying a capacity having a relatively large current.

[0002]

[Prior Art]

 In the conventional power supply terminal, as shown in FIG. 3, two mounting holes 2a 1 and 2b provided in the terminal body 2 are formed in a round hole shape having the same diameter.

[0003]

[Problems to be solved by the device]

 In the conventional technology, the two mounting holes 2a and 2b have the same standard round hole shape, and the hole spacing dimension of the two screw holes of the mating power supply terminal to be mounted is the same as that of the two mounting holes 2a and 2b. It requires an accuracy that closely matches the spacing dimension.

In this case, when two individual terminal blocks are installed to secure the capacity, the mounting dimension becomes a reference of the assembly tolerance. Therefore, in order to secure the processing dimension accuracy of the mounting holes 2a and 2b. If a special assembling jig or process is required and it is not used, the hole centers do not match during screwing and assembling, which often results in poor connection.

An object of the present invention is to provide a power supply terminal adapted to absorb an assembly precision tolerance.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the power supply terminal of the present invention is a power supply terminal having two mounting holes in a terminal body, wherein the one mounting hole is formed in a round hole shape. The other mounting hole is a long hole that absorbs the tolerance of assembly accuracy.

The other mounting hole has an elongated hole shape extending in the longitudinal direction of the terminal body.

[0008]

[Action]

 In the present invention, the mounting hole has a round hole shape, and the mounting hole has an oval shape with a center offset.

The round hole-shaped mounting hole is required to have the position of the terminal in order to secure the dimension from other objects, structures, etc., and therefore, it is necessary to have one center point.

The other elongated hole-shaped mounting hole absorbs a defect caused by a difference between the standards of part processing accuracy and assembly accuracy within a tolerance range allowable in assembly accuracy.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A is a plan view showing an embodiment of the present invention, and FIG. 1B is a side view of the same.

In the figure, the terminal body 1 has two mounting holes 1a and 1b.

The one mounting hole 1a is formed in a round hole shape. Here, the mounting hole 1a is necessary to determine the position of the terminal from the dimensions of other objects, structures, etc., and is formed in a round hole shape having one center point.

The other mounting hole 1b is formed in the shape of a long hole extending in the length direction of the terminal body 1, and absorbs the assembly precision tolerance.

FIG. 2 shows an assembled state using the power supply terminal according to the present invention.

In FIG. 2, 3a is a circuit board on the power-supplied side, 3b and 3c are power receiving terminal blocks of the circuit board on the power-supplied side, and 3d is a solder portion in which the power receiving terminal blocks 3b and 3c are fixed to the circuit board 3a. ..

The hole center size of the terminal blocks 3b and 3c fixed on the circuit board 3a by soldering is inferior to the machining accuracy of the mounting holes 1a and 1b of the power supply terminal due to the accuracy according to the assembly tolerance standard, but it has a long hole shape. The mounting hole 1b can absorb the mounting accuracy difference 3e. As a matter of course, the allowable value is a fixed amount, and the difference of 3e shows an example.

[0019]

[Effect of the device]

 As described above, according to the present invention, it is possible to sufficiently comply with a standard that is normally applied without requiring special assembly accuracy, thereby reducing the assembly man-hour and fixing the temporary position. Tools, and special mounting holes on the power-supplied side, to eliminate extra design and restrictions on the circuit, enabling mass productivity and cost reduction, and excluding deterioration of quality due to connection failure. , The improvement can be secured.
