The upper terminal pin 100 has a protrusion 120 for receiving the nut 30 and preventing the nut 30 from separating from the screw before fastening the nut 30 to the screw 10.

The protrusion 120 may be configured to press and support the lower portion of the nut 30 and preferably has a shape protruding upward toward the nut 30 as shown in FIG. . As a result, the nut 30 can be restrained in the upper body 110.

The pressing part 131 of the connecting member 130 extends to the lower portion of the upper terminal pin 100 along the connecting direction W of the lower terminal pin 200, 200 are inserted.

For example, the pressing part 131 may have a sloped shape that slopes inward to reduce the size of the gap as it goes down. The size of the lowermost gap of the pressing part 131 is smaller than the size of the lower terminal pin 200).

The guide portion 133 may have a shape extending downward from the pressing portion 131 and guiding the entry of the tip portion 230. The shape that enlarges the size of the gap as it goes down Lt; / RTI >

For example, the guide-shaped portion 133 may be formed to be wider toward the lower side of the pressing portion 131, and may be inclined or rounded.

According to this structure, the lower terminal pin 200 can be easily inserted into the gap through the guide portion 133 at an initial stage. The connection of the lower terminal pin 200 can be stably maintained by the pressing action of the pressing part 131 after the tip 230 enters.

In another embodiment, the guide portion 133 is formed to extend downward from the pressing portion 131 to guide the insertion of the tip portion, and a shape that keeps the size of the gap constant as it goes downward Lt; / RTI >

As described above, in the case of the terminal block for an electronic device according to the embodiment of the present invention, the connection of the upper and lower terminal pins 100 and 200 is easy, and the connection state can be stably maintained.

Reference numeral F1 in FIG. 6 denotes a force required to insert the lower terminal pin 200 through the connecting member 130 of the upper terminal pin 100, that is, the insertion force F1.

For example, the insertion force F1 is preferably small, meaning that the lower terminal pin 200 can be inserted into the upper terminal pin 100 with a relatively small force.

Reference numeral F2 in FIG. 7 denotes a force for pressing the lower terminal pin 200 inserted through the connecting member 130 in the direction crossing the connecting direction, that is, the forward force F2.

For example, it is preferable that the forward force F2 be large. The fact that the forward force F2 is large means that the connection state between the upper and lower terminal pins 100 and 200 is stable, and stable connection can be maintained.

Reference numeral F3 shown in FIG. 7 denotes a force required to separate and disconnect the lower terminal pin 200 connected to the upper terminal pin 100, that is, the pressing force F3.

In the terminal block for an electronic device according to the embodiment of the present invention configured as described above, the lower terminal pin 200 is inserted into the clearance of the upper terminal pin 100, and the terminal terminal pin 200 is easily inserted by the guide- The connection state can be firmly maintained.

8 is a view briefly showing an electronic device to which a terminal block for an electronic device according to an embodiment of the present invention is applied.

Referring to FIG. 8, the electronic device 1000 is a PLC (Programmable Logic Controller) product used as an automation device in each process of a smart production line. A plurality of terminal blocks T for an electronic device according to an embodiment of the present invention may be assembled into the electronic device 1000 and used for power and input / output signal transmission.

As described above, according to the configuration and operation of the present invention, it is possible to smoothly connect upper and lower terminal pins constituting the terminal block for an electronic device, so that the upper and lower terminal pins can be easily assembled.

Further, it is possible to prevent connection failure between the upper and lower terminal pins constituting the terminal block for the electronic device.

Furthermore, since the structure for preventing the nut member assembled inside the upper terminal pin to be engaged with the screw member is prevented, the convenience of the terminal block wiring work can be improved.

Although the present invention has been described with respect to a terminal block for an electronic device, it is apparent that various modifications can be made within the scope of the present invention.

It is to be understood that the above-described embodiments are illustrative in all aspects and should not be construed as limiting, and the scope of the present invention is indicated by the scope of claims for utility model registration described below rather than the detailed description, And all equivalents and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
