Description

[Detailed Description of the Invention] The present invention relates to a terminal block mounting device that can removably connect a terminal block and a printed circuit board built into a device, and can maintain a constant positional relationship between the two. .

When connecting a terminal block to a printed circuit board built into a device, conventionally, as shown in Figure 1, lead wire 1...
・It is troublesome to connect each end of the terminal to the wiring part 2A of the printed circuit board 2 and the terminal 3A of the terminal block 3 by soldering, etc., and once connected, it is not possible to separate the two, so it is difficult to inspect the equipment, It also had the disadvantage of making repairs and other work difficult.

Another disadvantage is that other mounting means must be used in order to maintain a constant positional relationship between the printed circuit board and the terminal block.

In addition, in order to electrically connect the printed circuit board and the terminal block and to maintain a constant positional relationship between them, the terminal block 3 is connected to the wiring section 2A of the printed circuit board 2 without using lead wires as shown in FIG. It was also possible to directly connect the terminal 3A of the terminal, but in this case too, troublesome connection work such as soldering is still required, and inspection and repair of the equipment becomes even more difficult. There was a problem.

The present invention was developed taking these circumstances into consideration, and its purpose is to connect the terminal block and the printed circuit board built into the device removably, thereby facilitating connection work, equipment inspection, repair, etc. It is an object of the present invention to provide a terminal block mounting device that facilitates work and is capable of maintaining a constant positional relationship between the two at the same time as electrical connection.

Hereinafter, the configuration of the present invention will be explained based on the embodiments shown in FIG. 2 and thereafter.

First, the embodiment shown in FIGS. 2 and 3 will be described.

In the figure, 11... is the wiring part 12A of the printed circuit board 12 incorporated in the device and the terminal 1 of the terminal block 13.
Each connector 11 has a threaded portion 14 at one end and a small-diameter insertion portion 15 at the other end, as shown in FIG. 3. are doing.

Further, a conductive cylindrical body 16 is attached to the printed circuit board 12 by penetrating through the wiring portion 12A, and a conductive plate spring 17 is provided inside the cylindrical body 16 to prevent the support 18 from being mounted. However, the insertion portion 15 inserted into the cylindrical body 16 is elastically held by a leaf spring 17.

The cylindrical body 16 has a flange 16A on the outer peripheral edge of one end, is inserted into a through hole provided in the printed circuit board 12 from the other end, and is fixed to the wiring portion 12A by soldering 19.

On the other hand, each terminal 13A of the terminal block 13 is integrally molded in an insulator 13B made of synthetic resin, etc., and each has a screw hole 13C, into which the screw of the plug-in connector 11 is inserted. The portion 14 is adapted to be screwed together.

Therefore, if the plug-in connector 11 is fixed to the terminal block 13 by screwing in advance, the plug-in part 15 of the connector 11 can be connected to the terminal of the terminal block 13 by simply inserting it into the receiver 18. The wiring portion 12A of the printed circuit board 12 can be electrically connected, and at the same time, the positional relationship of the terminal block 13 with respect to the printed circuit board 12 can be maintained constant.

Therefore, in the terminal block mounting device configured in this way, the terminal block 13 can be attached to or separated from the printed circuit board 12 by inserting and removing the plug-in connector 11 into the receiver 18. Inspection and repair of the equipment can be carried out separately, making the connection work easy, and the work of inspecting and repairing the equipment can also be carried out extremely easily.

Furthermore, since the printed circuit board 12 and the terminal block 13 are electrically connected and installed at the same time, there is no need for additional work to fix the terminal block 13 to the printed circuit board 12, which simplifies the installation work. .

Next, in the embodiment of FIG. 4, one end of the plug-in connector 21 is connected to the terminal block 3.
According to this embodiment, the same effects as those of the previous embodiment can be obtained, and since the plug-in connector 21 is integrated with the terminal block 13, the structure is simplified. Effects such as further simplification and cost reduction can also be obtained.

Next, the embodiment shown in FIG. 5 is similar to the embodiment shown in FIG. 3, in which an insulating coating 22 is applied to the middle part of the plug-in connector 11, which has the effect of reducing the exposed area of the conductive part and increasing safety. is obtained.

Further, in the embodiment shown in FIG. 6, the insertion part 24 of the insertion connector 23 is bent at an angle of approximately 90', and the terminal block 13 is connected to the printed circuit board 1.
It is designed so that it can be attached at an angle of approximately 90° to the

As described above based on the various embodiments, according to the terminal block mounting device of the present invention, the receiver is fixed to the printed circuit board, one end of the plug-in connection tool is fixed to the terminal block, and the Since the connection between the two is made by inserting the connector directly across the receiver, it is easy to connect the terminal block to the printed circuit board, and the two can be separated when inspecting or repairing equipment. Work can be done easily.

Further, since the positional relationship between the two is maintained constant at the same time as the electrical connection, no special mounting means is required for fixing the terminal block.
