Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, fig. 2, fig. 3, and fig. 4, an embodiment of the present invention provides a wiring device suitable for a relay protection test, including: the connector comprises at least two connector lugs 1 and connecting wires 2 arranged between the connector lugs 1 to electrically conduct the connector lugs 1 with each other; the connector lug 1 comprises a plug connector 4 and a plug socket 3, wherein at least one part of the plug connector 4 and the plug socket 3 is made of conductive materials, and the plug connector 4 is electrically conducted with the plug socket 3, so that when the two connector lugs 1 are connected with each other, the plug connector 4 of one connector lug 1 is electrically conducted with the two connector lugs 1 when inserted into the plug socket 3 of the other connector lug 1.
The plug socket 3 is cylindrical and is provided with a hollow inner through hole, one end of the inner through hole is provided with internal threads to be connected with the plug connector 4, and the other end of the inner through hole forms an open plug space; the plug 4 is conical, and one end of the plug 4 is provided with an external thread to be connected with an internal through hole of the plug socket 3 so as to form a connector; the outer diameter of the other end of the plug 4 is matched with the inner wall of the plugging space of the plugging seat 3, so that the plug 4 is plugged into the plugging space of the plugging seat 3 of the other connector when the connectors are connected. As shown in fig. 2, an opening is formed in a sidewall of the socket 3, the opening being perpendicular to the axial direction of the socket 3, so that two ends of the connection line are respectively fixed in the opening and fixed with the socket 3 and electrically connected. Wherein the connecting wire 2 comprises a middle conducting wire and an outer insulating sheath.
Fig. 1 and 2 show an embodiment of the present invention having two connector lugs. It will be understood by those skilled in the art that a plurality of connector terminals may be included, and the connector terminals are electrically connected to each other through star-shaped connecting wires. When the connector is used, the two wiring devices can be connected into a whole by using the connector, and all the connector terminals of the two wiring devices are electrically conducted; the connectors can be sequentially spliced together so that the connectors of the wiring devices are electrically conducted.
The embodiment of the invention provides a secondary combined wiring mode of a relay protection device, which is efficient and convenient, and solves the problems that the wiring of the device in a test is complicated and time-consuming due to the fact that a large number of terminal pins are used in the conventional wiring mode. Compared with the traditional terminal contact pin, the contact pin combination part can be directly inserted into a wiring terminal of the device, and the size of the contact pin combination part is more matched with that of a common terminal. Wherein, metal contact can be dismantled, when not needing the mutual short circuit of secondary wiring, can external tester output wiring. The problem of large wiring workload and long wiring time in the traditional wiring mode is avoided, accurate wiring of the relay protection device is guaranteed, and the debugging period of equipment is shortened. Compared with the traditional wiring mode, the relay protection secondary combined wiring designed by the invention does not need to use a traditional wiring contact pin. Because the design of the metal contacts is matched with the size of the terminals, the metal contacts can be distributed over each terminal interface, and each input and output of the device can traverse the whole test process. The efficiency of wiring is also greatly improved compared with the traditional wiring mode, and the test period is shortened.
