Description

Conductor binding device for connection terminal block {APPARATUS OF CONNECTION TERMINAL FOR CONNECTING LEADING WIRE}

The present invention relates to a conductive wire binding device of a connection terminal block. Specifically, the conductive wire flowing into the insertion hole for binding the electrical wire is configured to be pressed between the conductive plate and the lower end of the conductive wire binding check piece on the hinge shaft lightly coalesced with a spring. The present invention relates to a conductive wire binding device of a connecting terminal block formed to have a bend extension portion in which an end of the conductive plate is bent so that the electrical conductor in the case of being inserted obliquely from the connecting terminal block can be reliably made.

Conventionally, tightening is performed by turning the bolts with a tool such as a screwdriver that can tighten the conductor fastening bolts in order to perform the operation of binding the electric conductors, and the wires introduced into the insertion hole by the applicant are lightly coalesced with the spring. Starting from the electrical connection terminal block of the Republic of Korea Utility Model 1995-0008243, which is configured to be squeezed between the lower end of the check piece for binding wires on the hinge shaft and the conductive plate, the patent number 0115666, the patent number 0119883, the patent number 0124768, the patent number 0147510, etc. There is a continuous technological progress in the field by applying for the connection terminal block.

The structure and operation of such a conventional connection terminal block will be described with reference to the connection terminal block shown in FIG.

When the coating material is peeled off the conductive wire 1 is pushed through the lower insertion hole 40 of the push button 50 installed inclined to the connection terminal block 100 of the conductive wire binding check piece 10 condensed on the hinge shaft 70 The front end of the conducting wire 1 is pushed forward while the lower end of the conducting wire binding check piece 10 is rotated clockwise while compressing the spring 21 installed in the inclined spring receiving groove 21 and the The wire binding check piece 10 is inserted with a gap formed in the inclined conductive plate 3, and then the wire binding check piece 10 is rotated counterclockwise by the repulsive force of the spring 20. It is configured to be able to come into contact with, and then stop without further rotation and electrically fasten the conductor 1 as shown in FIG. 2A.

The connecting terminal block 100 using the repelling force of the conductive wire binding check piece 10 and the spring 20 is conveniently removed by a simple operation of removing the end covering of the conductive wire 1 and inserting it into the insertion hole 40. It is widely used in recent years by making the connection to the electrical.

However, such a conventional connection terminal block sometimes occurs when the electrical connection is not made completely, the most representative case of such a case is shown in Figure 2b as shown in the insertion hole (40) inserted into the insertion hole (40) In the process of pushing inwards, the conductor 1 is not normally contacted with the protrusion of the conductive plate 30 by being inserted in an obliquely bent state by an excessively applied force.

In the abnormally inserted state as shown in FIG. 2B, the conducting wire 1 and the conductive plate 30 are not electrically contacted to prevent energization, and the fixing protrusion 2 capable of installing a plurality of connection terminal blocks in parallel can be provided. In order to determine which connection terminal block in such an abnormal state by the field and the fixing grooves (not shown), there was an inconvenience of conducting an energization test through the metering hole 60 one by one.

On the other hand, sometimes even when the conductors are normally inserted, electrical contact of the conductors may not be achieved as the positions of the inserted conductors are slightly changed due to the load or vibration of the conductors outside the connection terminal block.

The present invention is devised to solve the problems as described above, the object of the present invention is that when the lead wire is inserted in a state in which the lead wire is bent in the connection terminal block for electrically connecting the lead wire into the insertion hole It is to improve the reliability of the connection terminal block by providing a configuration that can prevent the electrical non-contact state that can be generated.

Another object of the present invention is to allow the conductor inserted into the connection terminal block to be held continuously so that the position of the inserted conductor is not distorted in order to prevent electrical non-contact occurrence that may occur as the position is displaced by load or vibration. In providing.

Another object of the present invention will be described in more detail in the configuration and operation to be described later.
