Description

Technical Field

[0001] The present invention relates to the technical field of communication testing, and in particular to a testing tool. Background Art

[0002] Wired communication is a type of communication method. In a narrow sense, modern wired communication refers to wired communication, which is a method of transmitting information using tangible media such as metal test wires and optical fibers. The transmitted electrical or optical signals can represent sound, text, images, etc.

[0003] Since optical fibers are easily damaged and have high requirements for the environment, metal test lines are usually used to achieve wired communication in poor environments. Before using metal test lines for long-distance communication, the communication capability needs to be tested. The existing long-distance communication test method is to connect two communication devices at both ends of a test line that meets the length requirements for testing. For example, when performing a 1000-meter length test, two communication devices are connected at both ends of the 1000-meter test line. However, the test length of this test method is fixed. If you want to test communications at different distances, you need to prepare multiple test lines of different lengths, which leads to high testing costs. Summary of the invention

[0030] like Figure 1 and Figure 2 As shown, a test tool provided by an embodiment of the present invention includes a mounting box 10, a plurality of connection terminals 20, a plurality of test wires 30 and a plurality of connectors (not shown).

[0031] A plurality of connection terminals 20 are connected to the installation box 10 , and each connection terminal 20 has a first interface and a second interface.

[0032] A plurality of test wires 30 are disposed in the installation box 10 , and both ends of each test wire 30 are connected to a corresponding connection terminal 20 , and one end of the test wire 30 is connected to the first interface, and the other end is connected to the second interface.

[0033] Each connector can be detachably connected between any two connector terminals 20 , and one end of the connector is connected to the first interface of one of the connector terminals 20 , and the other end of the connector is connected to the second interface of the other connector terminal 20 .

[0034] Wherein, each first interface or each second interface is connected to a connecting piece.

[0035] It should be explained that each first interface or each second interface is connected to a connector, which means that each first interface and each second interface cannot be connected to two or more connectors.

[0036] It can be understood that the connector can connect any two connection terminals 20, and each first interface or each second interface is connected to a connector, so it can be determined that each connector is used to connect the two connection terminals 20 in series, and the two ends of the test line 30 are respectively connected to the first interface and the second interface, so each connector can connect the two test lines 30 in series.

[0037] By setting up the above-mentioned test fixture, a communication device is connected to the first interface of one of the connection terminals 20, and another communication device is connected to the second interface of another connection terminal 20, and then more connection terminals 20 are connected in series between the two connection terminals 20 through a connector as required, that is, multiple test lines 30 are connected in series, so as to realize long-line communication test between two communication devices. In this way, different numbers of test lines 30 can be connected in series as required, and test lines 30 of different lengths can be connected between two communication devices to perform communication tests of different distances. There is no need to prepare test lines 30 of different lengths for different test lengths, which saves costs.

[0038] It should be noted that the length and number of the test lines 30 can be determined according to actual needs. In this embodiment, the number of test lines 30 is 20, and the length of each test line 30 is 100 meters. When performing a 100-meter communication test, two communication devices can be directly connected to the first interface and the second interface of the same connection terminal 20, respectively.

[0039] When conducting a communication distance test of n×100 meters (n is a positive integer less than or equal to 20), a communication device is connected to the first interface of one of the connection terminals 20, and another communication device is connected to the second interface of the other connection terminal 20, and then n-2 connection terminals 20 are connected in series between the two connection terminals 20, so that a communication distance test of n×100 meters can be achieved.

[0040] at the same time, Figure 2 It is only used to illustrate the installation method of the test line 30 and is not used to indicate the number of the test lines 30 .

[0041] It can be confirmed that both ends of each test line 30 are connected to a corresponding connection terminal 20 , so the number of the test lines 30 is the same as the number of the connection terminals 20 .

[0042] In addition, if Figure 2As shown, each test line 30 has an insulating layer on the outside, and each test line 30 is wound and arranged in the installation box 10 .

[0043] It should be further explained that, in this embodiment, the test tool is applied to the fire protection field, specifically used to test the communication between the detector and the controller. Of course, in other embodiments, it can also be applied to other fields, which is not limited here.

[0044] In some embodiments, the installation box 10 includes a box body 11 and a cover plate 12, the box body 11 has an installation cavity 111 and an opening 112 connected to the installation cavity 111, multiple test lines 30 are arranged in the installation cavity 111, multiple connection terminals 20 are connected to the box body 11, and the cover plate 12 is rotatably connected to the opening 112 of the box body 11 to cover the box body 11 during rotation.

[0045] Furthermore, one end of each connection terminal 20 extends into the installation cavity 111 to be connected to the test line 30 , and the other end of each connection terminal 20 is exposed outside the box body 11 to be connected to a connector.

[0046] It is understandable that the connection terminal 20 has a first interface and a second interface, and both the first interface and the second interface can extend from one end of the connection terminal 20 to the other end to extend into the installation cavity 111 and be exposed outside the box body 11 respectively.

[0047] In some embodiments, the box body 11 further defines a plurality of terminal installation openings connected to the installation cavity 111 , and each connection terminal 20 is installed in a corresponding terminal installation opening so that both ends of the connection terminal 20 extend into the installation cavity 111 and are exposed outside the box body 11 .

[0048] Furthermore, a plurality of terminal installation openings are located on the same side of the box body 11 , so as to facilitate operators to connect the connection terminals 20 externally through connectors.

[0049] In actual applications, the plurality of terminal installation openings are arranged in an array along the height direction and the length direction of the box body 11 .

[0050] It can be understood that the plurality of terminal installation openings are arranged in an array along the height direction and the length direction of the box body 11 , which means that the terminal installation openings are located on the side of the box body 11 with the largest area.

[0051] Furthermore, when the connection terminals 20 are connected by the connector, adjacent connection terminals 20 are preferentially connected in order to ensure the aesthetics and convenience of the connection, and connection terminals 20 that are adjacent along the length direction of the box body 11 are preferentially connected.

[0052] In some embodiments, the box body 11 is further provided with a plurality of reserved installation openings 113, each of which is connected to the installation cavity 111, and the shape and size of the reserved installation openings 113 are the same as those of the terminal installation openings. In this way, when further test lines 30 and connection terminals 20 need to be added later, the connection terminals 20 can be installed in the reserved installation openings 113.

[0053] In actual applications, multiple reserved installation openings 113 and multiple terminal installation openings are located on the same side of the box body 11, and the multiple reserved installation openings 113 are arranged in an array along the height direction and the length direction of the box body 11 to facilitate the subsequent installation and connection of the connecting terminals 20.

[0054] In some embodiments, the installation box 10 further includes a plurality of positioning posts 13 . The plurality of positioning posts 13 are all disposed in the installation cavity 111 , and each test line 30 is wound around a corresponding positioning post 13 .

[0055] In some embodiments, the connection terminal 20 is a 4PIN interface terminal, which can facilitate the connection terminal 20 to be simultaneously connected to the two ends of the test line 30 and two connectors. At the same time, the connector and the test line 30 can both transmit electrical signals. The connector and the test line 30 can both be wires. The length of the connector is much smaller than the length of the test line 30, so the effect of the length of the connector on the test distance can be ignored.

[0056] In some embodiments, the testing tool further includes a plurality of rolling elements (not shown), and the plurality of rolling elements are all disposed at the bottom of the installation box 10 to facilitate the movement of the installation box 10 .

[0057] In practical applications, the rolling element is a roller, and a plurality of rollers are disposed at the bottom of the box body 11 , that is, the surface of the box body 11 facing away from the cover plate 12 .

[0058] In some embodiments, the testing tool further includes a handrail 40 , which is connected to the installation box 10 to facilitate the movement of the installation box 10 .

[0059] In actual application, the handrail 40 is connected to a side surface of the box body 11 adjacent to the terminal installation opening, and one end of the handrail 40 away from the box body 11 protrudes from the top of the box body 11 .

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
