Description

BACKGROUND OF THE INVENTION The present invention relates to a distribution connector for a community cable television network, which is provided with an input port and an output port receiving an input signal transmission line and a split signal transmission outlet. The proposed distribution connector is suitable not only for community cable TV networks but also for general purpose telecommunications systems.

The cable systems of public broadcasting networks are implemented in a variety of configurations, usually consisting of a cable from a relay or distribution station in which the signal transmitted through the cable is distributed to the subscribers of the system. The distribution is done at multiple points along the cable line. The process is to receive the input signal in the distribution connector, cut off a portion and distribute it, while the remainder is forwarded to the next distribution connector connected to the network. When it comes to a splitter that does not separate a signal for subscribers, the term "splice" seems to be more correct than a splitter. This does not mean, however, that the following applies only to the distribution connectors, which mainly serve the transmission function.

Many networks are deliberately set up in such a way that subscribers, in addition to program-specific signals, also degrade the performance of their receivers on this closed network. Preferably, the operator of the central unit transmits power to the pre-pump 20 via the cable line connecting the distribution terminals, utilizing the main cable. Therefore, the cable is preferably configured to transmit power, usually a low frequency AC signal and a high frequency signal such as a radio frequency signal corresponding to a program. In this case, it becomes an additional task of the distribution connector to share power, that is, to drain some of the power from the incoming combined signal and transmit it to the subscriber.

-2Plugged connectors that are known and are currently on the market may not always be able to meet the specific operational or network requirements outlined above with the required reliability. Therefore, depending on the number of subscribers on each distribution connector, different configuration of distribution connectors had to be used depending on the amount of attenuation required and the amount of power to be disconnected. Reducing the number of different variants is expedient in every respect, and as a result there is a need for a distribution connector which is essentially modular in design.

Our goal is to meet this need.

Our task is to create a distribution connector that is capable of transmitting combined signals and providing the conditions needed to decouple power, while modularly designed to reduce the number of different types of distribution connections required to establish a network.

In order to solve this problem, a distribution connector is provided which is particularly useful for establishing cable television networks having an inlet for receiving an input signal and an outlet for receiving an output signal, and an outlet for conducting a split signal. a first part separator and a physically detachable circuit for supplying the second part of the input signal from the inlet to the connector, and for disconnecting the detachable circuit between the inlet and the connector.

In accordance with the present invention, a splitter connector 25 formed with an inlet for receiving an input signal and an outlet for receiving an output signal, and an outlet for conducting a split signal, is a novel feature of the invention. a signal separating part of the power from the signal and a part of the power supplying to the outlet, and a detachable power distribution module having said disconnected part of the power and having at least one power transfer output.

It is highly desirable to provide an embodiment of a distribution connector according to the invention, wherein the physical removal of the circuit is adapted to establish an electrical connection between the inlet and outlet and thereafter electrically interrupt the connection of the circuit with the inlet and outlet. the circuit is assigned an unstable position during generation that does not offer the possibility of interruption.

For safety reasons, it is desirable to provide a distribution connector according to the invention in which the circuit is mounted on a removable cover element forming part of the circuit housing and when the housing is opened, the circuit can be removed and optionally formed on the removable cover element.

Installation is facilitated by a preferred embodiment of the distribution connector according to the invention, wherein the outlet is associated with the removable cover on opposite sides and the removal and replacement or replacement of the cover is interrupted or established between the outlet and the electrical circuit. causes. Generally, the recommended distribution connector is provided with at least two outlets.

It is also advantageous from the point of view of assembly for an embodiment of the distribution connector according to the invention which is at least partially mounted on a base plane and the movable elements of the switch are movable parallel to the base plane.

As mentioned, a preferred embodiment of the distribution connector of the present invention is configured at the input port for combining a first portion of the power with a combined power and means for disconnecting a high frequency signal from the resulting signal and adapted to transmit another portion of the power to the terminal. In this case, the isolation device is physically separated from the removable circuit and is not capable of transmitting essentially high frequency signals.

From a practical point of view, an embodiment of the distribution connector of the present invention which directs a first portion of the power to the designated output outputs is provided, and the distributor is provided with a plurality of outlet openings having the same number of openings. It is highly desirable to have a distribution connector according to the invention in which the power distribution module is provided with a low-pass filter or optionally provided with an inlet hermetically separated from the environment by means of a gel.

Also, for practical reasons, a preferred embodiment of the distribution connector of the present invention is a cable grip, accessible from the top surface of the housing through an opening and enclosed by a sleeve in which the sleeve is forced to contact one edge of the opening when the contact is connected. causing a sealed connection between the distribution connector and the outer surface.

Fig. 14 shows another possibility of designing a removable cover for a distribution connector according to the invention.

In accordance with the present invention, first of all, there is provided a distribution connector or a splitter (branching element) for use in the creation of community cable television systems, the structure of which essentially follows Figure 1. Fig. 1 shows a distributor 1 having housing 2 formed with a plurality of different openings. The openings in the housing 2 are accessible from the surface, through which input and output cables and wires can be routed, while its internal electronic circuits and switches assist in performing the required functions, thus dividing the input signal and / or separating the high frequency component from the power source. provide the necessary damping.

The hub 1 shown in FIG. 1 is located at a plurality of designated points of the main cable for cable TV networks, where the signal is to be shared or handed over to a particular subscriber. Therefore, it is provided with a distribution input 1 (3 inlets, if it is part of a distribution network 1, or 4 connections for distribution) and receives a cable that receives a signal from a control panel serving the cable television system or the like. Its output (i.e., an inlet 5 when part of a distribution network 1, or a port 6 if it is used for sharing) is also capable of receiving a cable which returns the forward signal or the remainder of the signal to the social network, e.g. it is forwarded to a distributor 1 having a structure similar to that shown here. Distributor 1 disconnects a portion of the input signal and delivers it to an outlet 7 which forms, for example, a branch cable to the subscriber. The number of outlet openings 7 can be varied as required, so that the distributor 1 can be provided with more than one, for example up to eight such openings.

The hub 1 does not necessarily serve to connect the main cable, whether it is working on a network line or involved in the distribution and distribution of the input signal. In this case, it is sufficient to create only the inlet 3 or 5 or only the connection port 4 or 6. Unused openings are covered, sealed or sealed as needed.

Televisions or other equipment powered by the signal transmitted by the distributor 1 are generally connected to an external power source, which is usually supplied with 60 V AC. However, the required power can very well be provided by the distributor 1 which delivers it to the inlet 3

It is picked up by a main cable inserted into -6 or 4 connector slots and distributed as needed. The main cable thus receives a power signal in combination with a high frequency signal (for example, a radio frequency signal, usually abbreviated as RF).

Here again, the power transmission cables are inserted into the outlets 7 from which they lead to the consumer and these cables are also suitable for transferring power combined with the high frequency signal to the subscriber. This solution may be appropriate, but should be avoided if the subscriber does not operate the unit at 60V or around, so do not expect such a voltage on the splitter cable. In this case, the power supply should preferably be provided from a separate power line.

The distributor 1 is accordingly provided with a power outlet 8, and therefore a portion of the power received on the input cable line is cut off by the distributor 1, delivered to the outlet 8, while the remainder is transmitted through the inlet 5 or connection 6 and so it goes to the next 1 hub in the network. If necessary, the distributor 1 is provided with a low pass filter which separates the high frequency signals from the distributed power signal and prevents them from passing.

Alternatively, the distributor 1 may be formed by a notch 9 or similar recesses, possibly protrusions, which, at the appropriate aperture, facilitate the task of isolating the input cables and may be suitable for catching sealing caps.

2A. Figures 1 to 4 show an arrangement similar to the distributor 1 shown in Figure 1. 2A. Fig. 4a is a rear elevational view of the distributor 1 in a substantially planar section, substantially parallel to the level of the paper carrying it. 2B. 2A. Fig. 2C is a plan view along the arrows shown in Figs. and 2D. Figures 1 to 4 show the distributor 1 in a direction perpendicular to the preceding direction.

2A, 2B, 2C. and 2D. Figures 1 to 5 show the housing 2, the inlet 3 and the connection opening 4 of the distributor 1, the inlet 5 and the connection opening 6, as well as the openings required for making the hand.

Appropriate openings allow the connection of coaxial cables, but this obviously does not preclude the use of other types of cables. Preferably, recesses are provided in which cable distribution terminals built into the cable end can be inserted, or where appropriate, to accommodate stripped-end cables. The inner conductor of the coaxial cable is connected to pin 10, while the outer conductor can be connected to pin 11.

The distribution connector of the present invention uses a switch 12 comprising movable contacts 12A and 12B for electrically connecting the inlet 3 and the connector 4 to the inlet 5 and the connector 6. As a result, when the switch 12 is closed, the input signal directed from the inlet to the connection port passes through the distributor 1 according to the invention without any part being distributed.

Switch 12 should be opened when the circuits needed for the hand are inserted. The direct current path between the inlets and the connection openings is then interrupted, after which the distribution circuit provides the necessary electrical connection and the distribution of the divided portion to the conductor in the outlet 7. 2A, 2B, 2C. and 2D. 1 and 2, the switch 12 is shown closed. The circuit can also be mounted on a removable cover plate, thereby providing the circuit shown in FIG. 2A. 9A, when placed in place, increases the distance between the movable contacts 12A and 12B.

The lower surface of the housing 2 is defined by a metallic element, such as in Fig. 2B. The wall on the right can be used as a reference plane. The structure of the switch 12 is preferably such that its moving parts move in a plane parallel to this reference plane, since in this case the high frequency characteristics of the distributor 1 do not change as the moving contacts 12A and 12B move.

The use of the switch 12 is advantageous even if the switching circuit is not used, its presence facilitating the operation of further switches 1 in the network. Removal of the hand circuit may be desirable, and may be replaced by other circuits as needed, such as multiple or less branching, hand circuits, modules carrying repair and modification units. It is recommended that the removal of the circuit does not cause any momentary malfunction of the circuit, so the physical removal process should ensure that:

1. maintaining an electrical connection between the inlet 3 and the connector 4;

2. electrical disconnection of the circuit between the input and the connector.

Subsequent switching of the circuit must have similar consequences, in which case a current path between the inlet and the connection opening is created through the circuit, the direct connection being made by actuating the switch 12.

-8When connecting between the inlet and the outlet through the switch and the splitter connection circuit, prevent the circuit from staying in place. Therefore, it is expedient for the circuit to move, during the change of position, to a position at which the connection is established, disconnection has not yet taken place and which position is unstable.

It is highly desirable that a single movement (such as moving out of the door 2 along a straight line) provides the required connection or disconnection. It is also advantageous when the physical removal itself is the one that establishes the connection or provides an interruption, for example, instead of using a pop-in or opening a locking member.

Preferably, the switch 12 may be mechanically or optionally electronic, preferably activated mechanically by direct mechanical and physical movement of the circuit or cover member, which may be provided with an outwardly extending member for its grip.

2A, 2C. and 2D. As illustrated in FIG. 6A, a power connector is used in the distribution connector of the present invention to supply power transmitted from the inlet 3 or the inlet 4 to the inlet 5 or terminal 6, thus providing power to a designated subscriber or subscriber group. Preferably, the power transmitting element 13 acts as a low pass filter or other low frequency power transmitting element, i.e., after being processed, the transmitted signal lacks the high frequency, radio frequency and the like signals that are essential for broadcasting. This is particularly advantageous if the power transmitting element 13 is essentially utilized as a power disconnection device that provides power to subscribers. Alternatively, power may be deducted from the center point of a coil. An example of such a possibility is shown in Fig. 1, according to which the outlet 8 can be utilized for this purpose.

The power transmitting element 13 thus optionally performs a filter function in the distributor 1 or its body. Although its filtering function may be satisfactory, additional filtration may be required. This additional filtering may be provided by the additional power distribution module described below.

3A. 3B and 3B. Fig. 4A shows the removal of the cover closing the outlet 8. The lid may also be removed by simple pulling or unscrewing, as described in a

3A. but when made as part of the housing 2 of the distributor 1, a

The cover integral with or permanently attached to the material of the housing 92 shall be cut as shown in Fig. 3B. is shown.

According to Fig. 4, the distributor 1, together with the cover removed from the outlet 8, can be located on an outer surface of the housing 2. In this case, a sealing material 15, such as a gel or the like, is used to seal the interior of the outlet 8. A power distribution module 16 is connected to the distributor 1, for example, internal and external coaxial contacts 17 are provided in the current path, which are formed in the module 16, while matching outlets are provided in the outlet 8.

The module 16 may be clamped to the housing 2 by a snap or other connection with the damper 19A, but may optionally be provided with a pin or other element provided in the opening 19B.

According to Fig. 5, the module 16 is preferably arranged and gripped on the surface of the housing 2. It is particularly preferred that the module 16, which is a removable unit, does not alone provide power distribution or separation of the high frequency signal from the input signal. Even more advantageous is the arrangement whereby the units for the initial distribution of power are placed in a protected position in the body 2 of the distributor housing.

The 16 modules are capable of performing one or more functions considered necessary. Module 16 may be capable of distributing power by distributing power received at outlet 8 in housing 2 of distributor 1 to at least two 20 outputs and / or at outlet 8 having two or more different types of outputs such as outputs, by means of which 21 distributors with twisted wire pairs can be realized. This type of power transfer outputs can be equipped with structural solutions to prevent insulation movement and to prevent wire slipping. Each of the outlets preferably has means for connecting two wires, so that both members of the twisted pair of wires 21 can be gripped simultaneously. Each of the outputs uses a gel or other material or structure that can perform the function of isolating it from the environment. The number of outputs is basically equal to the number of outlets, since in most cases each subscriber has a system that requires a dedicated power line.

A further or alternative function of the module 16 may be filtering. The distributor 1 is generally not provided with a filter by itself, so that high frequency signals cannot be removed from the input power unless a separate filter unit is constructed. Here

-10 ···· can be assisted by 16 modules that provide filtering functionality in low-pass or other domain as needed.

As an additional or alternative option, we also create an electrical protection (security) arrangement. Module 16 can be supplemented with overcurrent or surge protection, so that no current or high voltage is present in the arrangement that damages circuits or components for receiving and transmitting signals, or damage equipment to the subscriber station. The protection means are also suitable for protecting subscriber equipment against overcurrents or surges on the main line between the two distributors. These auxiliary units are preferably rebootable devices and, more particularly, are automatically started. Examples of overcurrent protection devices include conductive polymeric materials, such as those marketed by Raychem as Polyswitch.

Figures 6, 7 and 8 show examples of how the cables 22 are to be secured and sealed in the outlets 7. As shown in FIG. 6, the cables 22 terminate in distribution terminals 23 which are secured by screws or other suitable fasteners to the outlets 7. The distribution terminals 23, the sections of cables 22 adjacent to them and their ends, are protected against environmental influences, for example by pulling through a sleeve 24. Preferably, the sleeves 24 are provided with an elastic plastic material within their interior, optionally containing a sealing material 15, such as a jelly, and a snap-on member 26 which engages as a latch after being inserted into the notch 9 of the outlet. The surface of the sleeves 24 may be corrugated, which may facilitate their bending, extension, and compression. One of the sleeves 24 is shown before being pushed into the outlet 7, and is provided with a cover 25 capable of closing the cable passage and thereby closing the sleeve 24 to an empty opening. To illustrate the internal structure, the sleeve 24 is shown in partial excision.

Figure 7 shows an alternative way of sealing the sleeve 24. Shown here is a sealing sleeve 27 which is capable of encircling a particular through body and can therefore be placed around a cable 22 when inserted into the outlet 7. The sealing sleeve 27 is comprised of two parts, which are connected to one another along the joint 28 and, by means of their snap elements, keep the respective openings closed. The distributor connector 23 can be secured to the outlet 7 by means of a special tool 30, which is particularly useful if the distributor connector 23 is too short and does not protrude sufficiently from the surface of the outlet 7 as shown in the figure at top right. ··· ···· Sci. The sealing sleeves 27 surrounding the sealed member can be secured in position by snaps 26 and a notch 9 to create a situation in which re-opening is not possible without damaging the elements and is advantageous because the distributor 1 receives long-lasting protection. unauthorized access, unauthorized removal of the signal.

The sleeves shown in Figures 6 and 7, and in particular the sleeve shown in Figure 6, can be used with different sizes of cables and openings.

8A, 8B. and 8C. FIG. 6A shows how a particular opening can be sealed with an outer sleeve following the structure shown in FIG. 6 or FIG. Here, an outlet opening 7 is shown which, in particular, has a threaded contact 7A which is accessible through an opening 32. The opening 32, defined by the protruding surface of the cylindrical wall surrounding the threaded contact 7A, is formed on the outer surface of the distributor 1. A sleeve 33 is provided around the threaded contact 7A, and when the distribution connector 23 is clamped to the threaded contact 7A by means of a thread or otherwise, the sleeve 33 is forced to contact the edges of the opening 32, which when properly applied to the distribution connector 23 between the outer surface and the seal means airtight sealing.

Figures 9 and 10 show an arrangement of a wrap-around seal and / or sealing sleeve 27 for sealing the main cables 35 in the respective openings. The sealing sleeve 27 may comprise a gel or other sealing material. In structure, it resembles the sleeve shown in Figure 7, the difference being in size, the sleeve 27 being larger.

Figure 11 shows a bellows-type sleeve 24 surrounding the main cable 35, similar in structure to the sleeve shown in Figure 6.

Fig. 12 shows a sealing cover 36 containing a gel or other sealing material for closing the connection opening 4. The figure shows a sealing cover 36 in position.

The sealing cap 36, the sleeve 24 and the sleeve 27, and other means of isolating from the environment, may be provided, if necessary, with means for applying the gel or sealant therein or otherwise used therewith. tenable. It may be necessary to keep the sealant under pressure since it may be in contact with the surfaces to be sealed. Compression is also made possible by the resilience of the covers and sleeves and / or the housing 2 of the distributor 1. Alternatively, additional or alternatively snap-in sliding elements may be used.

-12A sealant preferably comprises a gel based on a polymeric, oil-grown plastic. Preferably, this composition has a ball pressing of 80 and 400, preferably 200 and 400 (10 ' ¹ mm) according to ASTM D-21768, having a tensile elongation of at least 100% (as measured by ASTM D-638-80), but preferably at least 200%. A further preferred limitation is that the tensile strength measured according to ASTM D-412 is at least 1 MPa, and its dynamic elastic modulus is at least 50 kPa at 100 ° C, preferably at 120 ° C. Materials having such properties, in particular gels, have the essential advantage that they are self-sealing. This means that the conditions for isolation from the environment are automatically recreated after the cable, wire, module or circuit board is removed.

13 and 14 show the distributors 1 with housing 2 and cover 37. As shown in Figure 13, the cover 37 is provided with a physically removable circuit having a disconnecting member 38. A portion of the disconnecting elements 38 serves to disconnect the first portion of the incoming signal at the inlet 3 and to transmit it to the outlet 7, while the other portion of the incoming signal is also provided to the corresponding terminal 6. 13 and 14, these openings are shown closed. By removing the cover 37, the housing 2 can be opened and the circuit can be removed. It is expedient to carry out the lifting of the circuit in such a way that the elements involved in the power distribution are not forced to change their position within the housing 2.

As shown in Figure 13, the outlet openings 7 are mounted on the opposite surface 39 of the distributor 1 to the cover 37 at the distributor connector, thereby removing or replacing the cover 37 causes the current path between the electrical circuit and the corresponding opening to be interrupted or re-established. Within the distributor 1, a plurality of distribution connectors (not shown) may be provided for each of the outlets and inlets, which may form parts of the electrical circuit at particular points.

Referring to Figure 14, the outlet openings 7 are provided with a removable cover 39 '. The connection between the outlets 7 and the electrical circuit may be permanent, but the disadvantage is that when accessing the interior of the distributor 1, when replacing the covers and the circuit, the outlets 7 must be used and the elements therein touched. need.
