Description

Electrical or Telephone Line Connectors {COUPLING TERMINAL OF ELECTRIC WIRE OR TELEPHONE WIRE}

The present invention relates to an electric cable or a telephone line connection terminal has the characteristics that the usability, safety, workability, etc. are excellently improved compared to the conventional terminal.

A terminal for connecting an electric line or a telephone line is one of the parts that are widely used at present. In addition to a lead terminal 500 having a hole 502 formed at the end thereof as shown in FIG. 8, one side of the hole 502 is opened to open the fork type. Some lead terminals are made of metal. Meanwhile, as shown in FIG. 2, dozens or more connection terminals are installed in the control box or the terminal box while being fixed by the fixing device 7, and the lead terminal 500 is connected to the connection terminal as shown in FIG. 2. .

By the way, as shown in FIG. 8, the lead terminal 500 has a hole 502 formed at the end thereof, or as described above, when fixing the fork lead terminal having one side of the hole 502 open to the connection terminal, the screw And nuts are used. Of course, the method of pinching wires using spring elasticity is somewhat applied to home appliances, but this is difficult to apply to connection terminals of electric wires or telephone lines due to problems such as poor contact and detachment of wires.

Again, there are a number of problems with the current method of fixing the lead terminals using screws and nuts as described above.

In other words, the structure of fixing the lead terminal by using screws and nuts may lead to poor contact or separation of the lead terminal if the screw is tightened somewhat, and that the screw thread may be damaged or the lead terminal may be damaged if the screw is too tight. In addition, when the lead terminals are connected to dozens or more of the connection terminals, each screw is tightened to fix the lead terminals. Therefore, there is no easy way to visually check that the screws are tightened and not tightened. Therefore, the problem of contact failure and the occurrence of fire due to this can not be solved, and the cumbersome and economical loss of rework is inevitably accompanied. In addition, since the screw fixing the lead terminal is exposed, a short may occur due to inadvertent handling of the tool or the lead terminal during work, which may cause a safety accident. In addition, there is a risk that the screw may loosen from the nut and come off due to vibration, which may cause contact failure or fire.In addition, if the screw is lost, there is no way to immediately fix the lead terminal to the connecting terminal. In addition, because the part of the lead terminal and the screw is exposed to the naked eye is not stable and has a problem that is not good to see.

On the other hand, with these problems, it takes a lot of time and workability to loosen the screw from the nut, insert the lead terminal or insert the screw into the hole 502, and then tighten the screw on the nut to fix the lead terminal It is difficult and has a problem of poor work efficiency. In addition, since the screw must be released from the nut one by one even when the lead terminal which is already fixed from the connecting terminal is also accompanied by problems such as poor workability and inconvenient work efficiency.

Therefore, the present invention uses an electric wire or telephone line connection terminal that can fix and release the lead terminal very simply and firmly and safely with one-touch using a fixture that is separated from vertical to horizontal without using screws and nuts. To provide.

To this end, the present invention, the groove 14 which can be inserted into the fixing rail 5 is formed downward and the groove 14 is inserted into the left and right of the end 12 is formed in the center is formed, the end 12 The protrusion jaw 13 is formed at the center of the vertical plate body 11 to be connected to the end 12, and the body 15 is formed with a hole 15 into which pins can be fitted on the left and right sides of the protrusion jaw 13. 10; Contact with the body 10 to form a set with the body 10, the hole 62 is formed in the concentric position with the hole 15 of the vertical plate body 11 can be fitted to the fixed rail (5) downward A cover 60 having a groove formed therein; A brass plate 30 inserted horizontally between the protruding jaw 13 and the end 12 of the body and having a jaw 32 inserted into the hole 502 of the lead terminal 500 on the left and right upper surfaces thereof; A spring 20 inserted into the groove 14 of the body to push up the brass plate 30; Pins 50 for supporting the fixture 40 while being inserted into the holes 15 and 62 of the body and the cover and the holes 42 of the fixture 40; It is characterized by consisting of a fixture 40 to restrain the lead terminal 500 fitted to the jaw 32 of the brass plate 30 while being supported by the pin 50.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to Figures 1, 3, and 4 corresponding to the basic embodiment of the present invention, the body 10 is formed with a groove below the fixing rail 5, which is a conventional Since the connecting terminal has the same structure as shown in the drawing, detailed description thereof will be omitted. Here, the body 10 is slidable in the longitudinal direction of the fixed rail on the fixed rail (5) by inserting a plurality of connection terminals manufactured one by one in the fixed rail and the fixing device (7) on both sides as shown in Figure 2 Make sure that the connectors do not move on the fixed rail before use.

On the other hand, Figure 2 shows a view in a plan view of the state in which the lead terminal 500 is fixed by the fixture 40 of the present invention, as well as the brass plate 30 and other parts of the lead terminal at all You can see that it is not exposed. That is, unlike the related art, the connection terminal of the present invention only exposes the fixture 40 and the protruding jaw 13 of the body, which are assembled between the vertical plate 11 and the cover 60 of the body 10, and the lead terminal 500. ) Or brass plate 30 is not exposed at all, gives a sense of safety and stability, and also has an aesthetic appearance.

The body 10 and the cover 60, the fixture 40, etc., except for the springs 20 and 80 and the brass plate 30 of the present invention are all made of plastic, and the body 10 and the cover 60 are It is the same color and the fixture 40 has a different color so that the part where the lead terminal is connected (the fixture is aside) and the part that is not connected (the fixture is upright) can be seen at a glance. It would be desirable, but there is no reason to distinguish colors unconditionally.

Subsequently, a stage 12 is formed at the center of the body 10, and grooves 14 for inserting the spring 20 are formed at the left and right sides thereof, and the stage 12 is formed at the center of the vertical plate 11. Protruding jaws 13 are formed to face each other while maintaining a spacing. And the left and right sides of the protruding jaw 13 of the vertical plate body 11 to form a hole 15 into which the pin 50 is inserted.

In addition, the upper surface of the brass plate 30 inserted horizontally between the end 12 and the protruding jaw 13 so that the jaw 32 having a diameter that can be inserted into the hole 502 of the lead terminal is formed to face each other. do. On the other hand, the brass plate 30 when the fixture 40 is open is always held up by the elasticity of the spring 20 is inserted into the groove 14 of the body so that the upper surface of the central portion of the brass plate of the protruding jaw 13 It is in contact with the bottom.

In addition, the fixture 40, which is easy to be fixed or pressed by a fingertip, that is, a “￢” shape, has a hole 42 formed therein, so that the pin 50 can be inserted therein, and the pin 50 has a body. The fixture 40 is rotated with the pin 50 as the center of rotation while being inserted into the hole 15 and the hole 62 of the cover 60.

The cover 60 forms a set in contact with the body, and prevents the spring 20 and the brass plate 30 and the separation of the fixture 40 and the pin 50 and keeps it in place. When it is necessary to replace or repair the spring 20, the fixture 40, the brass plate 30, etc., the body 10 must be separated from the body 10, so that the bonding or screw assembly with the body 10 no need. Moreover, the body 10 and the cover 60 are integrally assembled because the body and the cover are assembled on the fixing rail in a pair as shown in FIG. 2 and fixed by a separate fixing device 7 so that the position thereof does not change. There is no reason to achieve this.

The usage of the present invention configured as described above will be described.

3 is a state in which the fixture 40 of the present invention is open, the brass plate 30 is held up by the spring 20 is in contact with the bottom surface of the protruding jaw (13). In this state, the end of the lead terminal 500 is lightly entered between the fixture 40 and the gap formed by the jaw 32 of the brass plate 30, and then the jaw 32 of the brass plate into the hole 502 of the lead terminal. At the same time, when the fixture 40 is affixed downward as shown in FIG. 4, the fixture 40 is held at right angles while pressing the jaw 32 of the brass plate downward. At this time, the brass plate 30 is still held up by the elasticity of the spring 20, but the upper surface of the brass plate is slightly separated from the bottom of the protruding jaw 13 by the pressing action of the fixture 40. It is located about halfway between the projection jaw 13 and the end (12). Therefore, the brass plate and the fixture are firmly kept in contact with each other by the elasticity of the spring, and the lead terminal inserted in the jaw 32 of the brass plate is also very securely and firmly maintained. Therefore, even if vibration or impact is applied to the present invention, the fixture 40 is almost out of position, and the lead terminal also does not have any problem such as being out of position or exiting from the fixture.

On the other hand, Figure 4 shows a state in which the lead terminal is fixed to the present invention, which can be seen at a glance that the lead terminal is securely fixed if the fixture is affixed downward while the lead terminal is connected as shown in the drawing. On the contrary, if the fixture 40 is upright as shown in FIG. 3 or the lead terminal is connected, but the fixture is upright, it can be seen at a glance that the work is not completed. Therefore, the present invention can know at a glance the connection and fixing state of the lead terminal.

On the other hand, in the state in which the fixture 40 is secured at right angles to secure the lead terminal as shown in FIG. 4, if the lead terminal is held in a fixed direction, that is, the lead terminal is grasped and pulled strongly upward, the fixture 40 is lifted up. The lead terminal may be separated from the brass plate. In order to prevent such a case, the cover 60 is provided with a groove 64 through which the protrusion pieces 16 are integrally formed on the vertical plate body 11 of the body and the end of the protrusion pieces 16 can be inserted safely. To form. Here, the position of the protruding piece 16 should be a place where it does not interfere with maintaining the right angle when the fixture 40 is removed as shown in FIG. 4 without being disturbed when the lead terminal is inserted onto the brass plate as shown in the drawing. Of course.

As such, when the protruding piece 16 is formed, the lead terminal is caught by the protruding piece 16 even when the lead terminal is fixed and pulled upward while the lead terminal is fixed as shown in FIG. 4, and the fixture 40 is not affected. That's why you can stay safer.

Meanwhile, the present invention devised as an application example in terms of preventing the fixture 40 from being lifted up as described above will be described with reference to FIGS. 5, 6, and 7. This is to assemble the stopper 70 in the lower portion of the fixture 40a as shown in Figure 7, the stopper 70 is formed so that the circular protrusion 74 is formed at the end of the plate 72, which is easy to grip with the fingertip At the bottom, the locking jaw 76 that can be caught by the protruding piece 16a is integrally formed. The fixture 40a is formed with a circular groove 44a into which the circular protrusion 74 of the stopper can be inserted, and a spring insertion groove 46a into which the spring 80 is inserted is formed at the bottom thereof. By the elasticity of 80, the stopper 70 is always kept in a state of being subtracted downward.

Therefore, the state in which the fixture 40a is opened while the stopper 70 is assembled is shown in FIG. 6, and after the lead terminal is positioned at the jaw 32 of the brass plate, the fixture 40a is squeezed downwards from FIG. 5. At the same time, the stopping jaw 76 of the stopper passes through the protruding piece 16a as if passing through, and is finally fixed to the bottom surface of the protruding piece 16a. Therefore, in order to open the fixture 40a in this state, hold the stopper 70 with the fingertip at the same time as the fixture 40a, and make the locking jaw 76 deviate from the protruding piece 16a, and then open the fixture 40a upward. Because of this, the fixed state of the fixture can be maintained more securely than in the case described above.

9, 10, and 11 are views showing another embodiment of the present invention, which shows a structure in which the fixture 40 once locked can not be opened again by using a finger, that is, the fixture can be completely locked. have. 9, 10, and 11, the locking step is formed on the upper end of the tungsten piece 18 formed by forming the gap 17 in the vertical direction on the left and right sides of the hole 15 of the vertical plate body 11 of the body 10. (19) is formed. Subsequently, the cover 60 is also provided with a locking jaw 69 at the upper end of the tungsten piece 68 formed by the gap 67. The locking jaws 19 and 69 are inclined as shown in the drawing. As shown in FIG. 10, when the fixture 40 is swung down, the fixture does not have a problem of sliding and falling. At this time, the tangerine pieces 18 and 68 are opened to the outside and the fixture 40 finally passes through the locking jaws 19 and 69 as shown in FIG. 11 so that the upper surface of the fixture contacts the bottom of the locking jaws 19 and 69. It takes a while. This state is completely hung to prevent the fixture 40 from being opened again by the locking jaws 19 and 69, and spreading the fingertips 18 and 68 outward with a driver or the like and then using the finger to fix the fixture 40. The absolute fixture 40 can not be opened before opening it, so that the best safety and stability are given.

The present invention as described above, by using a fixture that operates one-touch by removing the conventional lead terminal fixing structure using a screw and nut, it is possible to fix the lead terminal very firmly and securely, excellent workability and quick and accurate It is possible to work, which greatly improves the work efficiency, and eliminates the phenomenon of falling out of the lead terminal or falling out even if the vibration and shock are applied, thereby eliminating the occurrence of safety accidents, fire, civil complaints, etc. Since the parts such as brass plates are not exposed to the outside, short circuits do not occur due to inadvertent operation, and the safety and stable feeling and aesthetic sense are also improved, which increases the added value and leads the connection and fixing of the lead terminals. With a structure that can be seen at a glance, work efficiency is improved with accurate work. Has a number of useful effects, such as.
