Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a connecting terminal for connecting conducting wires, and particularly to a connecting terminal used for connecting lightning protection conducting wires.

The connection terminal of the present invention is widely used in the fields of lightning protection equipment and power distribution equipment.

[Conventional technology]

Conventional connection terminals are as shown in Figures 4 and 5.
The structure is such that the conductor is inserted into the cylindrical hole and fixed and connected with brass bolts.

[Problem to be solved] However, with the conventional structure of connection terminals, connections are made by crimping with bolts from one direction, so over a long period of time they naturally loosen, come off, or cause poor contact. Things were also hot.

For this reason, attempts have been made to join the parts by pouring solder into the insertion area, but the soldering process does not allow the solder to enter the cylinder properly. Solder flows out. Other issues remained.

Improving work efficiency was an important issue because the work site for wiring involves many obstacles such as steel frames or reinforced concrete dam frames, scaffolding pipes, etc.

This invention is particularly designed for pouring solder, and aims to achieve a complete electrical connection by pouring from one direction at the top.It also aims to significantly shorten working time and save on solder. That is.

[Means for solving problems]

In this invention, screws are provided alternately on the tubes of conductor connection terminals of various shapes to crimp the inserted conductor in a wave shape, and a solder injection hole is provided at the topmost position when the connection terminal is installed. The present invention provides a connection terminal characterized in that the terminals are fixed with screws, openings other than the injection port are closed with paper clay, and solder is poured into the solder injection port for bonding.

The screws are arranged alternately to prevent the conductor from falling off, and the solder inlet is provided at the topmost point during installation, making it easier to pour in the solder, and the hollow position of the screws allows it to flow into every corner. They devised a way to block the openings other than the solder inlet with paper clay so that the solder would not run off and the joint would look good.

[Effect]

In the connection terminal according to the present invention, conductor wires are inserted into left and right or vertical tubes, screwed in place, the openings from which the solder flows are wrapped with paper clay to block them, and solder is poured into the solder inlet to completely connect the conductor wires and screws. It is to be joined to.

There is no longer any loss of solder or run-off of solder that damages the appearance.

Once the solder has solidified and the bond is complete, the paper clay can be removed by hand or with a tool.

[Embodiment 1] Next, an embodiment of the connection terminal according to the present invention will be described based on the drawings.

The connecting terminal 1, which is formed in a plane shape, has a solder inlet 2 formed in the upper part (the top surface of each cylinder) when installed, and horizontal screws 4 are provided alternately from both sides of each cylinder 3. It is.

The solder injection port 2 is formed in the upper surface of each cylinder 3 as a long hole in the longitudinal direction.

The solder inlet 2 is located at the top of each cylinder 3.

The screws 4 are provided alternately so as to crimp the conductive wire 5 inserted into the tube 3 in a wave shape. Screw 4
By providing the screws 4 at alternate positions, the threading of the screws 4 becomes deeper and the conductor 5 can be crimped.
Since the space 6 is created inside the cylinder 3, there is an advantage that the solder 7 can flow evenly and continuously.

Also, since the screw 4 is screwed into the tube 3 from the side, there is no problem such as water droplets accumulating on the head of the screw 4 when installing it externally, and the head of the screw 4 does not get in the way during solder injection work. It has become a thing.

To explain the work procedure, the flat type connection terminal 1 is made by inserting the specified conductor 5 into each cylinder 3 and fixing it with screws 4, then wrapping paper clay 8 around the opening of each cylinder 3, and pouring solder. Solder 7 is poured continuously from the inlet 2.

Since the paper clay 8 is in close contact with the opening of the tube 3, it will not leak, and since there is an appropriate space 6 inside the tube 3, it can be poured continuously.

Since the paper clay 8 dries and solidifies due to the heat of the solder 7, the openings are not sticky with the solder 7, and workability is extremely good.

Since the solder 7 can also be used without any loss, the amount of solder is much smaller than in the case where the openings are not processed, which is economical.

[Embodiment 2] The vertical type connecting terminal 1 shown in FIGS. 2 and 3 has a wide mouth edge 9 formed in the upper third opening to serve as a solder injection port 2.

The vertical type connection terminal 1 connects horizontal conductor wires 5 in the vertical direction, and has a solder inlet 2 at the topmost position when installed, and horizontal screws 4 in each tube 3. This is because of the difference.

The connection work is completed by inserting the conductor 5 into the tube 3, fixing it with the screw 4, closing the side opening and lower end opening with paper clay 8, and pouring solder through the solder injection port 2 and solidifying it. .

Since the wide mouth edge 9 is formed at the opening of the upper tube 3,
For the first time, it became possible to inject solder, making the work easier.

〔effect〕

The connection terminal according to the present invention has the structure and function as shown in Examples 1 and 2 above, and has the following unique technical effects on wiring connections of lightning protection equipment such as connection of lightning conductors of lightning rods and other wiring.

Provides extremely strong conductor connections.

The durability and safety of the electrical connection are high, and there is almost no risk of it falling off.

The work involved screwing, paper clay wrapping,
Workability on site is good because solder can be injected continuously.

Further, since the solder does not flow, there is no need to clean up afterwards, and the appearance of the connection is also favorable.

For solder injection work, an injection port is drilled in the upper part, a screw is installed in a position that will not interfere, and a space is created in the cylinder, so continuous injection work from one direction is possible. This can be done efficiently.

As described above, the connection terminal according to the present invention satisfies on-site requirements and connection safety, and has significant practical value.
