Description

Terminal strip coupler for remote telecommunication connections to other mounting frames {DEVICE FOR COUPLING TERMINAL STRIPS FOR TELECOMMUNICATIONS CONNECTIONS TO DIFFERENT MOUNTING FRAMES}

Purpose of the Invention

The present invention relates to a device specifically designed for coupling or securing terminal strips used in telecommunications equipment to an associated frame or installation system.

It is an object of the present invention to indifferently secure various types of frames to terminal strips by means of the devices described below.

Accordingly, the present invention focuses on the field of remote telecommunications, and more particularly on switch storage and internal distribution frames that are frequently installed in public highways.

Background

As is known, a properly insulated cable package from a telephone switchboard arrives at a switch cabinet in which connections between different users are made via terminal strips, which are often placed side-by-side in a suitable mounting frame and used for this purpose. do.

For example, a widely used installation system is disclosed in PCT WO 97/12423, which comprises a U-shaped profile, since the U-shaped profile is known to be fixed to a structure and engages with a castle branch, The terminal strips can be coupled to each facing pair of castles and can accept any particular telephone number pair from the exchange and connect them to each user's callline.

However, the frames may have completely different shapes, for example in the form of a pair of parallel cylindrical rods spaced apart in the longitudinal direction of the terminal strip, as disclosed, for example, in European Patent ES2 050 165. Instead of connecting the tongue and grooved coupling channel to the frame of the frame as in the previous case, the terminal strip is pressurized at one end to form a stable convex coupling to the rod. It combines with the subprojections forming a cylindrical channel that slightly protrudes from the semi-cylinder. In this European patent, it may be an important improvement that the terminal strip is pivotable with respect to one of the rods, but it is nevertheless clear that the pivot connection is only suitable for empty terminal strips and the terminal strip When the wires are wound around the wires, the wires interfere with the pivot connection and thus lack practical utility.

PCT WO 97/12423 also discloses terminal strips formed to be joined to a frame in the form of two cylindrical rods, as shown in US Pat. No. 5,779,504.

In European Patent ES 2 050 165, since the terminal strip cannot be joined to the castle universal frame, a special terminal strip is only effective for this type of frame for joining the cylindrical rods, the two cited above. The terminal strips in the patent, PCT WO 97/12423 and US Pat. No. 5,779,504 are useful for use in castle universal frames, but because they cannot be used in cylindrical rod frames, this frame is a detailed description of which has By any connection that does not matter, it is designed to accommodate the auxiliary body of the universal terminal strip.

PCT WO 99/07163 discloses a terminal strip which can be coupled to a cylindrical rod as well as a rod having a different cross section, which is a pair of barriers acting as clips to gripping the rod. Use In this case, however, the terminal strip can also be fixed only to the rods of the type mentioned above and cannot be fixed or coupled to the universal universal frame.

Thus, all the above mentioned terminal strips have a common problem that they are designed for some particular type of mounting frame and cannot be used for other types.

In addition, the terminal strips must all be provided with a grounding means, which consequently has the problem of complicating the structure of the terminal strip and raising the price.

Detailed description of the invention

Coupling device according to the present invention for solving the above-mentioned problems, the conventional terminal strip, designed for the conventional castle frame, not only the castle frame frame, but also the load frame, and a load frame of a wide variety of rods The above problems are solved by allowing them to be installed in the same manner.

To this end, the device to be discussed in more detail consists of a pair of adapters, each of which is generally in the form of a flat body, the adapter being formed such that its ends are functionally similar to one of the castle features of the castle universal frame, This allows the adapter to be coupled to the universal terminal strip via this part of the thin plate body in the same way as the terminal strip is connected to the castle frame.

The other end of the adapter body extends substantially downward relative to the base of the terminal strip and forms a semi-gripper designed to receive the associated rod of the rod frame from the outside when the rod frame is used. .

Because in this way a pair of adapters work together with the terminal strip, the terminal strip can be coupled to the pair of rods by deformation and subsequent elastic recovery of the adapter forming a gripper as a unit. The gripper preferably grips the rod only by contacting the outer surface of each rod, which is substantially opposite from the space between the pair of rods. However, it is also possible to arrange and / or form the adapter to reverse the gripping action by contacting only the inward surface of each rod substantially facing each other with respect to the space between the pair of rods and to each other. It is possible.

According to another feature of the invention, in order to facilitate the installation and removal of the terminal strip, the adapter is installed so that the lower side of the adapter has a free end in the flange smoothly angled downward and outward.

The adapter is preferably made of metal, which not only fulfills the basic function as an elastic member forming the gripper, but also acts as a ground connection for the terminal strip.

As a form of the invention, it is preferred that some of the adapters forming the semi-gripper have a narrow U-shaped channel shape, which particular shape may also be applied to an acyclic cross-section rod, for example consisting of a square, triangular or polygonal cross section. Ensure that the terminal strips are connected well and even to waterway rods, ie concave and open rods and rods of simple platen shape.

Preferred contact lines are indicated by arrows in FIG. 6.

Regardless of whether the terminal strip 3 can be fixed to the castle frame 1, when the device according to the invention is not coupled to the castle frame, the device has a terminal strip in the cylindrical rod frame 6. In addition to being secured to, it also allows application to rods having a wide variety of shapes, as shown in FIG. As indicated by reference number 3, it is preferable to install the segment to support the body of the terminal strip and at least to install another two support lines for the adapter 8. More specifically, in the first representative figure 7a of this figure, cylindrical and tubular rods 6 'are shown, and also tubular rods are shown 6' in Figs. 7b and 7c. However, in the first case it is octagonal, in the second case triangular, and the rods 6 '' shown in the other three examples 7d, 7e, and 7f are L-shaped in the first case and T-shaped in the second case. In the third case, it is an inverted L-shape.

The solution for the rods 6'-6 '' is to strongly connect the surface or contact area between the rods and the adapter 8, which provides optimum contact conditions for the grounding of the terminal strip 3 Additional emphasis should be given.

Although the above descriptions have been made with respect to the terminal strip 3 fixed to the frame of the castle shape (or a channel which is not the castle shape) as shown in FIG. 3, the invention can be applied to a terminal strip of similar shape in another form. have.
