Description

Modular wire connection terminal and connection unit used there {Modular electrical connector}

The present invention relates to a terminal for modular line connection in which a plurality of connection units are mounted on a mount table, and in particular, it is possible to freely increase or decrease the mounted connection units and to reuse at least some of the components of each connection unit. A modular line connection terminal is possible.

In establishing a wired line such as a communication line or a transmission line, connection points are provided at a plurality of positions. Among them, the multi-line is concentrated in the terminal box connecting the outdoor line and the indoor line of the building, and the multi-line is connected to each of the indoor and outdoor lines according to the wiring design, so that dozens of pairs of terminals are installed. .

A commonly used terminal is a terminal in which wiring screws are installed at both ends of a metal pad for connection. After the terminal is stripped of the line to be connected, the indoor line and the outdoor line are connected by loosening the wiring screw, winding the stripped core wire around the stem of the screw, and then tightening the wiring screw again. It is to be connected to each other through the metal pad.

These terminals are not only cumbersome and time-consuming in many stages of the process, including the peeling process, but also the connection becomes poor when the screw is loosened due to vibration in the screw tightening process and vibration during use. The disadvantage is that the variation in resistance increase due to the connection is extreme.

In today's communication environment, where video communication is required to transmit much more data at a higher speed than voice communication or data communication, poor connection and increased resistance have a significant adverse effect on overall communication quality.

Various types of terminals have been released to replace such screw-connected terminals. Such a terminal is configured to connect a line by inserting an end cover of the line into the connection groove without removing the cover of the line, and then inserting a two-pipe connecting knife that can penetrate the core and touch the core wire. However, such a terminal is very difficult to put the wiring knives, in order to easily perform such a task must use a specially designed tool.

In addition, once the wiring knife has been inserted, it is impossible to remove it. Therefore, when the wiring design is changed or the line is replaced, the already used connection unit cannot be reused, and a new connection unit must be used. In addition, if there is no new connection unit that is not used in the terminal module that cannot be increased or replaced, the new terminal module must be added or replaced.

This invention is made in view of the disadvantages of the conventional line connection terminal as described above, and is intended to provide a terminal module free to increase or decrease the mounted connection unit.

In addition, each connection unit is intended to be configured so that the operator can easily connect by pressing the finger without the use of the line peeling or special tools.

In addition, each connection unit can be easily removed by reconnecting already connected lines, restored to the state before use, and reusable, and even if some components are damaged in the process of removing the connection, only the damaged components are replaced. You will configure it so that it can be recovered.

The portion where the first coupling leg 2250 and the second coupling leg 2240 contact each other is exposed to a groove formed on the upper surface of the main body 2100, and a safety blocking device is cut off when a momentary overload such as a surge voltage is applied therebetween. (Not shown) may be inserted.

FIG. 27 shows the connection unit 3000 mounted on the first to third mounting cells 1010 to 1030 in the modular line connection terminal in the state where the ten connection units 3000 of the third embodiment are mounted on the mounting table 1000. The line connection pressurizing port 3300 of) is fitted with a line drawn upward, and a line is already connected to the connection unit 3000 mounted on the 4-6 mounting cells 1040 to 1060. Lines fitted to the connection unit 3000 mounted on the nineth mounting cells 1070 to 1090 are arranged, and the front view of the connection unit 3000 mounted on the tenth mounting cell 1110 is in a state before use. have.

As can be seen from the connection unit 3000 mounted on the 10 mounting cell 1100, in the line connecting pressure port 3300 of this embodiment, two pairs of line insertions are inserted to insert the end of the line into the insertion part 3310. The ball is formed. The first pair of line insertion holes 3311 and 3312 on the upper side are used to connect relatively thick lines, and are larger in diameter than the second pair of line insertion holes 3313 and 3314 formed on the lower side.

While the invention is described in detail above based on the preferred embodiments of this invention, such embodiments are illustrative only and not intended to limit this invention. It will be apparent to those skilled in the art that the present invention can be adjusted, changed or changed from the above-described embodiment without departing from the spirit of the present invention. Therefore, the appended claims are intended to comprehensively cover such modifications, variations or variations.

The modular line connection terminal according to the present invention makes it possible to freely increase or decrease the connection unit to be mounted, and the operator can easily connect the wires with a finger without using the line peeling or the use of special tools. It can be easily removed and restored to the state before use, and reused. Even if some components are broken in the process of removing the track, the connection unit can be restored by replacing only the damaged components.
