Abstract

The utility model relates to a network cable testing instrument port extender cooperating with current small-size network cable testing instrument to simplify the twisted-pair wiring testing of computer network, comprising three more RJ-45 sockets (9) arranged in a close casing. The slot of the socket extends out; eight contacts (1), (2), (3), (4), (5), (6), (7) and (8) of each RJ-45 socket in the casing are parallel connected with each other with same arrangement.

Description

Network tester port expander

Affiliated technical field

The utility model relates to a kind of aided measurement device to computer network twisted-pair feeder wiring carrying out Validity Test, a kind of network tester port expander that can obviously improve computer network multiple twin line test efficient.

Background technology

Use the twisted-pair feeders wiring in a large number in the computer network engineering, whether its line preface correctness, telecommunications outlet and RJ-45 plug are connected with twisted-pair feeder and reliably will produce a very large impact network performance.Network company needs circuit is detected after wiring is finished, and the network user often need test institute's cloth website in row wiring, the acceptance of work, working service.At present, general networking company or computer network user adopt a kind of small-sized tester (as expert ST-248 type network cable tester) of cheapness that netting twine is carried out on off test.This tester has only a pair of test port, can only carry out point-to-point measurement to a netting twine at every turn.When, distance many when test station, particularly high building multilayer distributed, the circuit two ends will be frequently travelled to and fro between in one man operation, and two people measure then to be needed to coordinate, contact, the very loaded down with trivial details poor efficiency of test job.

Summary of the invention

In order to overcome existing mininet tester to the inconvenience of network layout test and not enough, the utility model provides a kind of network tester port expander, cooperate existing mininet tester only to need one man operation just can test institute's cloth website easily, improved efficiency of measurement greatly.

The technical scheme that its technical matters that solves the utility model adopts is: in closure, the Registered Jack-45 of three above quantity is housed, socket exposes.Eight contacts of each Registered Jack-45 by the aligned identical order respectively and connect in the shell.During measurement, the short twisted-pair feeder that meets network standard (pressing the wiring of EIA/TIA 568B standard usually) that has the RJ-45 plug with two ends links to each other network tester host test port with arbitrary interface of network tester port expander.Switch end at network line, the RJ-45 plug of desire test is inserted other port of network tester port expander, hand-held then network tester extension set directly arrives each end points one by one to its test, does not need to come and go at the circuit two ends, and a people can conveniently finish surveying work.

The port number of supposing network tester port expander is N, and the Validity Test port is expanded and is N-1.When test station more for a long time, can measure in batches or adopt a plurality of network tester port expander Cascading Methods to measure.When cascade was used, if the cascade number is m, the port of network tester port expander add up to n after the cascade, and then the Validity Test port of network tester main frame is expanded and is n-2m+1.

The beneficial effects of the utility model are: simple in structure, cost is low, can obviously improve netting twine test job efficient.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the utility model measuring principle synoptic diagram.

Fig. 3 is an embodiment structural map of the present utility model.

Fig. 4 is the internal structure side view of the utility model embodiment.

Fig. 5 is the printed circuit board (PCB) (23) that the utility model embodiment adopts.

Fig. 6 is that synoptic diagram is used in cascade of the present utility model.

In Fig. 1, its corresponding eight contacts (1) of Registered Jack-45 (9), (2), (3), (4), (5), (6), (7), (8) by the aligned identical order respectively and connect.

Among Fig. 2, the test port of mininet tester main frame (11) is inserted with RJ-45 by two ends The short twisted-pair feeder (12) of head and arbitrary RJ-45 socket (9) phase of network cable tester port expander (13) Connect, separately RJ-45 plug insertion network is passed through in the switch end wiring (15) of network line system (14) Other RJ-45 socket (9) of cable tester port expander (13) is with mininet tester extension set (16) Can be respectively to each end points of network line system (14) with the short twisted-pair feeder (17) of RJ-45 plug by two ends Telecommunications outlet (18) test one by one. If network line system (14) terminal does not have telecommunications outlet, can be with each The RJ-45 plug of end points directly inserts the test port of mininet tester extension set (16) netting twine is surveyed Amount.

Embodiment

In the embodiment shown in fig. 3,8 Registered Jack-45 (9) are welded on the printed circuit board (PCB) and are encapsulated in the shell (20), and socket exposes.(1X), (2X), (3X), (4X), (5X), (6X), (7X), (8X) are the port numbers of distributing for 8 Registered Jack-45 (9) among the figure.

Fig. 4 is the internal structure side view of the utility model embodiment, and 8 Registered Jack-45 (9) are welded on the printed circuit board (PCB) (23), and its eight contacts separately by the aligned identical order by printed circuit board (PCB) (23) respectively and connect.

Dotted line among Fig. 5 is the lead of welding between 2 of the printed wires.

Use in the synoptic diagram in cascade shown in Figure 6, the cascade number is 2, and total port number is 16, and effectively the Extended Capabilities Port number is n-2m+1=13.Mininet tester main frame (11) has the RJ-45 plug by two ends short twisted-pair feeder (12) is connected with arbitrary port (7X) of network tester port expander (22), and the short twisted-pair feeder (13) that has the RJ-45 plug with two ends is connected arbitrary port (8X) of network tester port expander (21) with arbitrary port (8X) of network tester port expander (22).Other port of network tester port expander (21), (2 2) is used for connecting tested netting twine.

The network tester port expander of an amount of port also can be incorporated in the main frame of network side line instrument.

Claims

A kind of network tester port expander is equipped with the Registered Jack-45 of 3 above quantity in closure, socket exposes, and it is characterized in that: eight contacts of each Registered Jack-45 by the aligned identical order respectively and connect in the shell.
