Abstract

PROBLEM TO BE SOLVED: To facilitate making connections between plural terminals without requiring a complicated shape of a bus bar by eliminating the effects of a difficult wiring work and a voltage drop. SOLUTION: A conductive connecting member 11 is connected linearly between adjacent terminal 6, 6. An insulating barrier 23 is provided between terminal groups 22A, 22B each of which is combination of the terminals 6, 6 connected by the connecting member 11. Since the insulating barrier 23 between the terminals 6, 6 are removed, a bus bar connected between the terminals 6, 6 is not required to be of a complicated shape. In addition, the connecting member 11 can be connected linearly in a place, where the insulating barrier 23 has been removed. Accordingly, a connection between the terminals 6, 6 by wiring can be dispensed with, and the problem of a difficult work accused by wiring and a voltage drop can be eliminated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal block in which a plurality of conductive terminals are arranged in parallel and an insulating barrier is provided between the terminals.

[0002]

FIG. 5 shows the structure of a conventional terminal block having a particularly large current capacity. In FIG. 1, reference numeral 101 denotes a base made of a plastic resin, and a plurality of conductive screws 102 are arranged on the base 101 at regular intervals. In addition, a flat washer 103 that forms a terminal together with the screw 102 is interposed in each screw 102. A pair of wall portions 104 are provided outside the screws 102 located at both ends from the base 101, and between the screws 102, the base 101 and the base 101 are secured in order to secure a creepage distance between the screws 102. An integral insulating barrier 105 is provided. Then, a crimp terminal (not shown) to which an electric wire is connected is held between the head of the screw 102 and the washer 103, and the screw 102 is screwed into the base 101. It is designed to be attached to and fixed to.

In the terminal block having such a structure, the current capacity per one terminal of the terminal depends on the diameter and material of the screw 102. When the current capacity is insufficient with a single terminal, as shown in FIG. Measures have been taken such as providing a bus bar 106 made of a conductive metal plate between the adjacent screws 102, or connecting the adjacent screws 102 with a wire (not shown). However, since the insulating barrier 105 is interposed between the screws 102 arranged in parallel, the bus bar 106 must be formed so as to straddle the insulating barrier 105, which complicates the shape of the bus bar 106. There was a problem. Furthermore, when connecting a wire between the screws 102,
Insulation barrier 105 interferes with wiring,
There is a problem that the working efficiency is reduced and the voltage drop due to the wiring becomes remarkable as the current capacity becomes larger.

[0004] In view of the above problems, the present invention provides a plurality of bus bars for increasing the current capacity without complicating the shape of the bus bar and eliminating the difficulty of wiring work and the effects of voltage drop. It is an object of the present invention to provide a terminal block which can easily connect the terminals.

[0005]

In order to achieve the above object, a terminal block according to the present invention comprises a plurality of conductive terminals arranged side by side, and at least an adjacent terminal block provided with an insulating barrier between the terminals. Two or more of the terminals are linearly connected by a conductive connecting member, and the insulating barrier is provided between the terminal groups connected by the connecting member.

According to this configuration, within the same terminal group,
Since the insulation barrier between adjacent terminals is removed,
The bus bar connected between these terminals does not need to be formed in a complicated shape. Further, since the connecting member can be connected linearly between the terminals by using the portion where the insulating barrier is removed, the shape of the connecting member itself is not complicated, and
The connection between the terminals by the wiring is unnecessary, and the problem of the difficulty of the work by the wiring and the problem of the voltage drop can be eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a terminal block according to the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 denotes a base made of a plastic resin, and a plurality of conductive screws 3 made of, for example, iron are arranged at equal intervals on a vertical flat surface 2 forming a front surface of the base 1. ing.
Each screw 3 has the same shape and the same material, and is composed of a male screw portion 4 screwed into the main body 1 and a head 5 provided at the tip of the male screw portion 4 to which a tool such as a screwdriver is fitted. You. Further, each screw 3 is provided with a spring washer 7 constituting a terminal 6 together with the screw 3 in a state of being inserted through the male screw portion 4.

On the back surface of the main body 1, there is provided an electrode portion 8 made of a metal plate member which can be soldered corresponding to each terminal 6. The electrode portion 8 has a pin 9 projecting below the bottom surface of the main body 1. The pin 9 is inserted into a hole of a printed board (not shown) and connected by soldering.
The main body 1 is mounted and fixed at a predetermined position on the printed circuit board, and the terminals 6 are electrically connected to the printed circuit board.

Reference numeral 11 denotes a connecting member formed of a conductive plate material for connecting the adjacent terminals 6 and 6. The connecting member 11 is provided with holes (not shown) corresponding to the male screw portions 4 and 4, and is formed so as not to protrude on the flat surface 2 and to have a linear shape without a notch or the like. Have been. In this embodiment, electrical connection between at least two terminals 6 and 6 is achieved by interposing the connecting member 11, but the number of connected terminals 6 may be three or more. Also in that case, the connecting member 11 is formed linearly.

The base 1 is located outside the terminals 6 located at both ends.
A pair of wall portions 21 are erected further forward, and
In order to secure a creepage distance between the adjacent terminal groups 22A and 22B, between the different terminal groups 22A and 22B composed of a combination of the terminals 6 and 6 connected by the connecting member 11,
An insulating barrier 23 integrally formed with the base 1 is provided forward. Conversely, terminals 6 and 6 in the same terminal group 22A
No insulating barrier 23 is provided between them, and the flat surface 2 of the main body 1 is formed, in which the linear connecting member 11 is provided. Reference numeral 24 denotes a detachable protective cover made of a transparent plastic member provided so as to cover each terminal 6, and reference numeral 25 denotes a groove that fits into the housing 26 of the power supply device.

In the terminal block having such a configuration, the terminals 6, 6 of the same terminal group 22A, 22B connected by the connecting member 11 can be connected without connecting wires between the terminals 6, 6. If electric wires and bus bars are connected, the current capacity can be easily increased by the plurality of terminals 6 and 6. In this case, the insulating barrier 23 is not provided at the place where the connecting member 11 is mounted, and the connecting member 11 can also be connected linearly. That is, as shown in FIG. 4, when connecting the wire 31 to the terminal group 22A, the crimp terminal 32 connected to the tip of the wire 31 is used.
And the male screw portion 4 of the screw 2 together with the spring washer 7

As a result, a current corresponding to the plurality of terminals 6 and 6 can be supplied to the terminal block. Also, the insulating barrier 23 is not provided at a location where the connecting member 11 is to be mounted, and the connecting member 11 can also be connected linearly. Therefore, the connecting member 11
Does not become complicated.

When a bus bar (not shown) is connected to the terminals 6 and 6 of the same terminal group 22A and 22B instead of the wire 31 having the crimp terminals 32, an insulating barrier is provided between the terminals 6 and 6. Since 23 is not provided, it is not necessary to form the bus bar in a complicated shape that straddles this portion. Therefore,
There is an advantage that the bus bar can be easily formed.

As described above, in the present embodiment, at least two or more adjacent terminals 6 are provided on a terminal block in which a plurality of conductive terminals 6 are juxtaposed and the insulating barrier 23 is provided between the terminals 6. 6 are connected linearly by a conductive connecting member 11, and an insulating barrier 23 is provided between terminal groups 22A and 22B formed by combining the terminals 6 and 6 connected by the connecting member 11.
