Problems that the invention aims to solve In such a conventional configuration, the input terminal is used for supplying power, for transmitting electricity to other devices, and for transmitting and receiving signals from the board 8 that has a control circuit, etc. ,
Not only does the number of screwless terminals 7 used in the device body 12 increase, but the number of lead wires 9 also increases and becomes thicker as the current capacity increases.
The storage work becomes difficult, and a large storage space is required, which inevitably increases the size of the container body 12.

This invention solves these problems,
By eliminating the lead wire that connects the screwless terminal and the board,
We have improved the ease of assembly and made the device more compact, and the connection part (solder part) is designed to be unaffected by external forces.
The purpose is to improve quality and reliability.

A terminal case is provided, and a terminal plate made of a conductive material and having a power supply terminal at an upper end and in contact with a connecting conductor is mounted in the terminal case, and a fitting hole is provided to engage with the hook part. The power feeding terminal is supported in a conductive state at a predetermined position on the board, a leaf spring is provided in the terminal case so as to sandwich the connecting conductor between the terminal plate, and the pressing of the connecting conductor is released by pushing the leaf spring. A screwless terminal provided with a release button is provided inside a container body consisting of an upper and lower case, and the protruding part of the terminal case is fitted into the opening of the lower case, and the bottom surface of the terminal case and the power supply terminal are respectively lowered. It is configured so as to come into contact with the case and the upper case.

Effect With this configuration, the power supply terminal of the terminal board is connected to the board in order to ensure the conduction of electricity between the terminal board that comes into contact with the connecting conductor and the board that mounts electronic components and constitutes the control circuit, etc., by eliminating the lead wire. The support position is determined by the fitting between the hook part of the terminal case and the fitting hole of the board, and when pushing or pulling out the connecting conductor from the screwless terminal, the terminal is fixed so that no external force is applied to the connecting part of the power supply terminal. The bottom surface of the case and the power supply terminal are provided in contact with the inner surface of the container body. This makes it possible to improve quality, reliability, and ease of assembly.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings (FIGS. 1 to 6).

Reference numeral 16 denotes a pair of terminal boards bent into a substantially U-shape using a conductive material, and is provided with a power supply terminal 16a that protrudes above the hook portion 13c of the terminal case 13, and is inserted into both terminal chambers 13b of the terminal case 13. It is installed. Reference numeral 18 denotes a leaf spring made of an elastic body, and is installed inside each of the pair of terminal plates 16. Reference numeral 19 denotes a release button movably mounted on one side wall of the terminal plate 16, which faces the engagement end 18a of the leaf spring 18 via the terminal plate 16. is also mounted inside the terminal case 13. 20 is a board on which electrical parts etc. that constitute a control circuit etc. are mounted;
Hook portion 13c of terminal case 13 and terminal plate 16
Fitting hole 20a located above the power supply terminal 16a of
and a terminal hole 20b are provided, and the terminal hole 20b and the electronic components of the board 20 are connected in a pattern, and when the terminal case 13 with each component mounted is attached to the board 20, the hook part 13c and the fitting hole are connected. 20a
The power supply terminal 16a is positioned by fitting into the terminal hole 20b, and then the power supply terminal 16a inserted into the terminal hole 20b is soldered and fixed to the board 20, thereby forming a screwless terminal 21.
A lower case 22 has an opening 22a formed in its bottom. An upper case 23 has ribs 23a on its inner surface, and the lower case 22 and upper case 23 constitute a container body 24. Insert the protruding part 13a of the terminal case 13 into the opening 22a of the lower case 22 so that it protrudes from the lower case 22, and lower the upper case 23 so that the rib 23a of the upper case 23 contacts the tip of the power supply terminal 16a. It is attached to case 22.

Here, when the connecting conductor 17 is inserted into the wire hole 14, since the elastic force of the leaf spring 18 is effective, the connecting conductor 17 is pushed toward the terminal plate 16 and comes into pressure contact with the terminal plate 16. Power can be supplied to the board 20 and signals can be transmitted and received. Conversely, when disconnecting the connecting conductor 17 due to incorrect wiring, etc., insert the screwdriver 25 into the driver hole 15, and the release button 19 moves in the direction of arrow A in FIG.
is separated from the connecting conductor 17, and the connecting conductor 17 can be easily detached and pulled out. At this time, be careful not to apply external force to the soldered portion between the power supply terminal 16a and the board 20 when inserting or removing the connecting conductor 17.
When plugging in, the tip of the power supply terminal 16a and the upper case 2
The ribs 23a of No. 3 are in contact with each other, and the bottom surface of the terminal case 13 and the inner surface of the lower case 22 are in contact with each other when the terminal case 13 is pulled out.

A second embodiment is shown in FIG. 5, in which a power supply terminal 16 is attached to an eyelet 26 which is caulked to a substrate 20 and soldered to a pattern to enable conduction with electronic components.
A is passed through and this part is soldered.

A third embodiment is shown in FIG.

Effects of the invention As described above, according to the invention, the hook part provided on the terminal case equipped with each component constituting the screwless terminal and the board fit together, and the power supply terminal of the terminal board comes into contact with the connecting conductor. By supporting it on the board, the lead wire for wiring can be eliminated, and the storage space for this lead wire is also no longer required.Assembly is easy and the device can be made more compact. Since the structure is such that no external force is applied to the structure, reliability can also be improved.
