Description

Technical Field

[0001] This application relates to the technical field of on-site calibration, and particularly relates to an on-site equipment calibration device. Background Art

[0002] During the on-site maintenance process, a calibration device is used to calibrate on-site equipment. Currently, when the existing calibration device is performing calibration work, due to the lack of obvious functional partitioning at the wiring connection of the existing calibration device, the wiring of the current, voltage, and switch quantity channels between the calibration device and the on-site equipment is chaotic. At the same time, the pluggable wires connecting the calibration device and the on-site equipment are not flexible enough to use, and problems such as incorrect wiring and cable entanglement are more likely to occur.

The voltage plug-in connector 5 is connected to the voltage plug-in interface 2; the plurality of voltage wires 6 are all arranged on the voltage plug-in connector 5.

The current plug-in connector 8 is connected to the current plug-in interface 3; the plurality of current wires 9 are all arranged on the current plug-in connector 8. One end of any one of the current wires 9 away from the current plug-in connector 8 is provided with a current plug 10 for connecting the device to be calibrated, and the plurality of current plugs 10 are spliced together to form a whole;

[0049] As Figure 6 shown, the digital input / output plug-in wiring includes a digital input / output plug-in connector 11 and a plurality of digital input / output wires 12. The digital input / output plug-in connector 11 is connected to the digital input / output plug-in interface 4; the plurality of digital input / output wires 12 are all arranged on the digital input / output plug-in connector 11.

[0050] In the above embodiments, during operation, the above voltage plug-and-play wiring, current plug-and-play wiring, and digital input / output plug-and-play wiring are respectively inserted into the above voltage plug-and-play interface 2, current plug-and-play interface 3, and digital input / output plug-and-play interface 4. At the same time, according to the corresponding functions of each plug-and-play wiring, the plugs (voltage plug 7, current plug 10, digital input / output plug 13) on each plug-and-play wiring are respectively connected to the on-site equipment to be calibrated as required, so as to carry out the calibration work on the on-site equipment. During its use, the plugs (voltage plug 7, current plug 10, digital input / output plug 13) corresponding to the respective cables (voltage cable body 6, current cable body 9, digital input / output cable body 12) can be independently disassembled from each other or spliced together to form a whole, and can be flexibly plugged and used according to actual needs, and it is also convenient to organize the cables and plugs, thus effectively avoiding the occurrence of incorrect connection, chaotic wiring and other situations, ensuring the safety of on-site equipment and staff, and improving the efficiency of calibration work.

[0051] As Figure 2 , Figure 4 , Figure 6 , Figure 8 shown, further, in some embodiments of the present application, a splicing block 14 is provided on any one of the above voltage plug 7, the above current plug 10, and the above digital input / output plug 13, and the multiple splicing blocks 14 located on the above voltage plug-and-play wiring, the above current plug-and-play wiring, and the above digital input / output plug-and-play wiring are spliced together to form a whole.

[0052] Further, in some embodiments of the present application, among the multiple splicing blocks 14 located on the above voltage plug-and-play wiring, the above current plug-and-play wiring, and the above digital input / output plug-and-play wiring, a splicing groove 15 and a splicing protrusion 16 that cooperate with each other are respectively provided on any two adjacent splicing blocks 14, and the splicing protrusion 16 is embedded in the splicing groove 15.

[0053] Further, in some embodiments of the present application, the cross-section of any one of the above splicing grooves 15 and any one of the above splicing protrusions 16 is in a T shape.

[0054] In the above embodiments, by using the structure of the splicing block 14 and the splicing protrusion 16 and splicing groove 15 between adjacent splicing blocks 14, the independent disassembly and integrated splicing of the multiple splicing blocks 14 are realized, so that each plug (voltage plug 7, current plug 10, digital input / output plug 13) and each cable body (voltage cable body 6, current cable body 9, digital input / output cable body 12) can be flexibly spliced and used according to actual needs, and it is also convenient to organize the cables, avoiding incorrect connection, chaotic wiring and other situations.

[0055] Specifically, as Figure 8 shown ( Figure 8The wire body and the plug (pin) part connected to the splicing block 14 are not shown in the figure. Usually, the plug (pin) part is arranged at the top shown in the figure, and the wire body part is connected to the bottom shown in the figure. The plug (pin) part and the wire body part are connected inside the splicing block 14. The above splicing block 14 can have three structural forms. One is the splicing block 14 with only the splicing groove 15 (such as Figure 8 the leftmost), the second is the splicing block 14 with only the splicing bump 16 (such as Figure 8 the rightmost), and the third is the splicing block 14 with both the splicing groove 15 and the splicing bump 16 (such as Figure 8 the middle two). During the actual splicing of the cable, the wire bodies (voltage wire body 6, current wire body 9, digital input / output wire body 12) where the splicing block 14 has only the splicing groove 15 or the splicing bump 16 are located at the edges of the overall cable (voltage plug-in wiring, current plug-in wiring, digital input / output plug-in wiring), while the wire bodies (voltage wire body 6, current wire body 9, digital input / output wire body 12) where there are both the splicing groove 15 and the splicing bump 16 are located in the middle of the overall cable (voltage plug-in wiring, current plug-in wiring, digital input / output plug-in wiring). In this way, the overall cable can be made more tidy and regular in appearance, and there will be no extra grooves or bumps on the overall shape after splicing, and to a certain extent, it can also play a role in identifying the orientation of the wire body.

[0056] Furthermore, different colors can also be painted on the above splicing block 14 according to the functions of the wire bodies (voltage wire body 6, current wire body 9, digital input / output wire body 12) where it is located for differential marking. Specifically;

[0057] In the above plug-in wiring and the above current plug-in wiring, it can be distinguished according to the specific functions of the wire bodies (voltage wire body 6, current wire body 9). For example, in a three-phase power system, the splicing block 14 arranged on the connector of each wire body can be painted yellow, green, red, and black respectively according to the phase A wire, phase B wire, phase C wire, and neutral wire to distinguish different functional wire bodies. In the above digital input / output plug-in wiring, the splicing block 14 corresponding to the digital input / output wire body 12 can also be painted blue and white respectively to distinguish the functions of the wire bodies, thus effectively avoiding situations such as wrong connection and misconnection.

[0058] Furthermore, in some embodiments of the present application, any one of the above splicing blocks 14 is integrally formed.

[0059] In the above embodiments, the overall structural stability of the integrally formed splicing block 14 is better, which is more conducive to use.

[0060] Further, in some embodiments of the present application, the above voltage pluggable wiring further includes a voltage integration wire housing 17, the voltage integration wire housing 17 is connected to the voltage pluggable joint 5, and a plurality of the above voltage wire bodies 6 are disposed through the voltage integration wire housing 17 and the ends extend to the outside of the voltage integration wire housing 17;

[0061] The above current pluggable wiring further includes a current integration wire housing 18, the current integration wire housing 18 is connected to the current pluggable joint 8, and a plurality of the above current wire bodies 9 are disposed through the current integration wire housing 18 and the ends extend to the outside of the current integration wire housing 18;

[0062] The above digital input / output pluggable wiring further includes a digital input / output integration wire housing 19, the digital input / output integration wire housing 19 is connected to the digital input / output pluggable joint 11, and a plurality of the above digital input / output wire bodies 12 are disposed through the digital input / output integration wire housing 19 and the ends extend to the outside of the digital input / output integration wire housing 19.

[0063] In the above embodiments, by using the integration wire housings (voltage integration wire housing 17, current integration wire housing 18, digital input / output integration wire housing 19), a plurality of wire bodies (voltage wire bodies 6, current wire bodies 9, digital input / output wire bodies 12) can be integrated into a whole, which is convenient for arrangement and can avoid the occurrence of situations such as cable chaos and entanglement; at the same time, the ends where the plugs (voltage plugs 7, current plugs 10, digital input / output plugs 13) of each wire body (voltage wire bodies 6, current wire bodies 9, digital input / output wire bodies 12) are located extend to the outside of the integration wire housing, so it will not have an adverse impact on the flexibility of their independent / spliced use.

[0068] Such as Figure 3 、 Figure 5 、 Figure 7As shown in the above embodiments, chamfers are respectively provided at different positions on the edge parts of each wiring area (voltage plug-in interface 2, current plug-in interface 3, digital input / output plug-in interface 4), and chamfers with the same orientation are also provided at the corresponding edge parts of the corresponding cable connectors (voltage plug-in connector 5, current plug-in connector 8, digital input / output plug-in connector 11), so as to play a "direction guiding" role in the connection and installation of the interfaces and connectors. At the same time, for the plug-in wiring areas with different functions, the corresponding chamfer positions are different from each other; for example, the chamfer positions of the voltage plug-in interface 2 and the voltage plug-in connector 5 are at the upper right corner, the chamfer positions of the voltage plug-in interface 2 and the voltage plug-in connector 5 are at the upper left corner, and the chamfer positions of the current plug-in interface 3 and the current plug-in connector 8 are at the upper left corner and the upper right corner (two chamfers), so as to ensure that misconnection situations such as inserting the current plug-in wiring (current plug-in connector 8) into the voltage plug-in interface 2 will not occur, thereby ensuring the safety of on-site equipment and staff, and being more conducive to work use.

[0069] Further, in some embodiments of the present application, a plurality of pin headers 20 are provided in each of the above-mentioned voltage plug-in interface 2, the above-mentioned current plug-in interface 3, and the above-mentioned digital input / output plug-in interface 4, and jacks 21 matching the above-mentioned pin headers 20 are provided in each of the above-mentioned voltage plug-in connector 5, the above-mentioned current plug-in connector 8, and the above-mentioned digital input / output plug-in connector 11;
