Description

Lightning arrester for protecting phone subscribers {A LIGHTNING ARRESTER FOR THE PROTECTION OF TELEPHONE SUBSCRIBER}

The present invention relates to a subscriber protection device consisting of a plurality of lightning arresters and a bullet base, and more specifically, is mounted on the bullet base to block subscribers to protect communication equipment and subscribers by blocking overvoltage and overcurrent flowing into the communication line. A lightning arrester of a protective device.

Conventional subscriber protection devices have to be stripped of wires and wrapped by wire wrappers on the terminal pins mounted on the bullet base, since the bullet base is a wrapping type. Not only does it require skilled skills of the operator, but it is also very difficult and has a long working time. In addition, even if perfect lapping, because of high contact resistance, the transmission speed is about 2-3M bps, which not only causes huge economic loss in PC communication but also degrades video and call quality.

Recently, subscriber protection devices have been introduced to improve workability and improve call quality and communication speed. However, the subscriber protection device, although the workability of connecting the communication line is greatly improved, it does not have a great effect on the improvement of the call quality and communication speed. It is connected to the terminal pin where the communication line is installed on the bullet base (primary connection), and the arrester pin contacts the connecting socket of the terminal pin (secondary connection), which is in turn connected to the arrester connector (final connection). Connections originate from a very complex line connection structure and have limited limitations in lowering contact resistance.

The present invention has been made to solve such a problem, and its object is to provide a lightning arrester of a new type of subscriber protection device which can reduce contact resistance as much as possible and has a simple configuration.

The structural feature of the present invention is that the input side connector 120 and the output side connector 130 has a quick clip type connection end to which a communication line is directly connected. The arrester of the subscriber protection device of the present invention having such a feature has an advantage of minimizing contact resistance by directly connecting the communication line to the input and output connectors, rather than the connection through a separate connecting part (terminal pin). have.

Again, referring to Figure 1 to Figure 6 in more detail look at the arrester configuration of the subscriber protection device according to a preferred embodiment of the present invention, the arrester 100 is a base 110, input connector 120, output connector ( 130, a ground connector 140, and a case 150.

The base 110 is provided with an input connector 120, an output connector 130 and a ground connector 140, the lower end of the pair of lugs 112 for fixing to the bullet base 200 (shown in Figure 6) ) Is formed. The lug 112 is formed with a groove 114 into which the protrusion formed in the bullet base 200 is fitted. The base 110 is formed with a fixing groove 116 into which the input side connectors 120 and the output side connectors 130 are fitted.

The base 110 and the case 150 have a mating protrusion 118 and a mating hole 158 to be coupled to each other. The case 150 is coupled to the base 110 by the combination thereof, and the connectors 120, 130, and 140 mounted on the base 110 are accommodated in the case 150.

The case 150 is orthogonal to the mounting slot 152 and the mounting slot 152 in which the connection ends 132 and 122 of the input side connector 120 and the output side connector 130 are located, respectively, and an electric wire is connected to the connection end. It has a fitting groove 154 to be fitted after being connected to (122,132). The case 150 has a ring 156 that is used to separate the arrester 100 from the bullet base 200 is formed on the upper surface.

Piece 126 and a bend 128 connected to the overvoltage arrester.

The connection ends 122 and 132 are made of a quick clip type having excellent contact resistance, which consists of grooves 122a and 132a having a pair of inclined blade surfaces to which a single wire is inserted and connected. Cable) is inserted into the grooves 122a and 132a, the outer skin is automatically peeled off and the core wire of the wire is connected to the connection ends 122 and 132.

Ground terminals 122 and 132 of the input connector 120 and the output connector 132 are inserted into the mounting slots 152 of the case 150, respectively.

On the other hand, the ground connector 140 is the clip portion 142 of the '142' shape that the overvoltage arrester 180 is fitted and the ground end 144 for grounding to the outside (tan-based ground bar) when the overvoltage is introduced. Has The ground end 144 is exposed to the bottom of the base 110 through a through hole formed in the center of the base 110. (It is concealed by the lugs of the base and is hard to see. See FIG. 5) As shown in FIG. As such, when the arrester 100 is mounted on the bullet base 200, the ground end 144 of the ground connector 140 elastically contacts a ground bar (not shown) installed in the bullet base 200. do. Preferably, the ground end 144 is formed by bending an end thereof so that the contact with the ground bar is made tight. The ground bar is connected to the ground wire.

As described above, when the arrester 100 of the subscriber protector of the present invention is connected to the bullet base 200, the ground end 144 of the ground bracket 140 of the arrester 100 is in contact with the ground bar for the ground. Has structural features.

Typically, two wires constituting a communication line are connected to the connection ends 132 and 122 of the input / output side connectors 120 and 130 of the arrester 100, which is obvious.

The lightning arrester 100 of the subscriber protector of the present invention has a communication line directly connected to the connection terminals 122 and 132 of the input / output side connector, thereby completely eliminating the increase factor of contact resistance, and promptly earths when lightning or high voltage lines flow. It is a product with high reliability and safety that can protect communication devices and subscribers.

In addition, the arrester of the present invention does not need the five connecting pins that are connected to each of the pair of input / output side connectors and the ground connector, thereby reducing workability and cost of parts thereof.

In the above, the configuration and operation of the arrester of the subscriber protector according to the present invention is shown in accordance with the above description and drawings, but this is merely described by way of example, and various changes and modifications may be made without departing from the technical spirit of the present invention. Of course it is possible.

Applying the present invention, the arrester of the subscriber protection device is completely connected to the input line connector and the output side connector, thereby completely removing the contact resistance increase factor.

Therefore, communication quality and communication speed are improved, and stable grounding is possible when overvoltage / overcurrent flows, thereby improving the reliability and safety of the product. In addition, by unifying the parts, there is an effect that can reduce the production cost of the product by reducing the overall number of parts.
