Description

Technical Field

[0001] This utility model relates to the field of vacuum contactors, and in particular to a convenient wiring platform suitable for testing FC vacuum contactors. Background Technology

[0002] As attached Figure 1 As shown, during preventative testing of the vacuum contactor switch, the D6 and C8 pins of the closing coil HQ and the D7 and B3 pins of the contactor KM1 need to be clamped. During opening, the C15 and D15 pins of the opening coil and the C12 and D12 pins of the opening contactor KM2 need to be clamped. Because the pins of the aviation connector are tightly packed, all eight pins cannot be clamped simultaneously, requiring separate clamping and opening operations, which wastes time and money. Furthermore, the following problems exist:

[0003] 1. Vibration during the test opening and closing may cause a short circuit between the positive and negative poles, resulting in burnout of the closing coil or contactor coil;

[0004] 2. Due to vibration during the opening and closing of the circuit breaker, a short circuit between the positive and negative poles caused damage to the triggering function inside the test instrument.

[0005] 3. Due to vibrations during the opening and closing tests, the test wires for opening and closing may come loose and need to be re-clamped. Utility Model Content

[0006] The purpose of this invention is to address the problems in the prior art by proposing a convenient wiring platform suitable for testing FC vacuum contactors.

[0007] A convenient wiring dock for testing FC vacuum contactors includes aviation plugs, aviation pins, guide rails, insulating boards, and terminal blocks;

[0008] The aviation plug is located on the side of the insulating plate;

[0009] The aviation pins and guide rails are both mounted on the surface of the insulating board;

[0010] The terminal block is located above the guide rail.

[0011] The function of the aviation plug is to connect electrical components through a plug-in function and transmit signals or current to the electrical components.

[0012] The terminal block is used to facilitate the use of a multimeter to measure the voltage on each terminal to check for faults.

[0013] Furthermore, a convenient terminal block for testing FC vacuum contactors is provided, wherein the number of terminal blocks is 8, arranged vertically above the guide rail.

[0014] The purpose of the guide rail is to prevent the terminals from sliding left and right during installation in the terminal block.

[0015] Furthermore, a convenient wiring dock for testing FC vacuum contactors is provided, wherein the aviation pins are fixed by bolts and an insulating plate.

[0016] Furthermore, a convenient wiring platform suitable for testing FC vacuum contactors is provided, wherein the insulating plate is provided with four bolts, and the aviation pins and the insulating plate are fixed by the bolts passing through the screw holes.

[0017] Furthermore, a convenient wiring dock for testing FC vacuum contactors is provided, wherein the aviation pin connection terminal block is provided.

[0018] Furthermore, a convenient wiring dock for testing FC vacuum contactors is provided, wherein the number of aviation plugs is 8.

[0019] Furthermore, a convenient wiring platform suitable for testing FC vacuum contactors is provided, wherein the insulating plate is 20cm long, 18.5cm wide, and 5mm thick.

[0020] Furthermore, a convenient wiring dock suitable for testing FC vacuum contactors is provided, wherein single-core soft copper wires are sequentially connected to the upper and lower ends of the terminal block;

[0021] The main component of the single-core soft copper wire is copper, and it is covered with an insulating material to prevent unsafe situations such as short circuits or leakage.

[0022] The beneficial effects of this utility model are as follows: By using a convenient wiring platform suitable for testing FC vacuum contactors, the eight pins for closing and opening are brought out externally, effectively solving the safety hazards and efficiency problems caused by vibration in FC vacuum contactor testing; eliminating the risk of positive and negative short circuits caused by vibration during the test, avoiding burnout of the closing coil or contactor coil; preventing short circuits caused by vibration from damaging the triggering function of the test instrument; completely avoiding the need to repeatedly check the wire clamps due to test leads falling off due to vibration; shortening the switching test time, significantly improving test efficiency, while reducing the risk of equipment damage and the frequency of manual intervention.

[0030] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0031] As attached Figures 2-5 As shown, a convenient wiring dock for testing FC vacuum contactors includes an aviation plug 1, aviation pins 2, a guide rail 3, an insulating plate 4, and a terminal block 5; the aviation plug 1 is disposed on the side of the insulating plate 4; the aviation pins 2 and the guide rail 3 are both disposed on the surface of the insulating plate 4; and the terminal block 5 is disposed above the guide rail 3.

[0032] Use an 8mm drill bit to drill four holes in the panel and insulation board to fix the insulation board. Use a 4mm drill bit to drill six and eight holes for aviation plug leads.

[0033] There are 8 terminal blocks 5, which are vertically arranged above the guide rail 3. The aviation pins 2 are fixed by bolts and insulating plates 4. There are 8 aviation plugs 1. The insulating plate 4 is 20cm long, 18.5cm wide and 5mm thick. The upper and lower ends of the terminal blocks 5 are connected with single-core soft copper wires, each 20cm long.

[0034] As attached Figure 6 As shown, a convenient wiring dock for testing FC vacuum contactors has the following circuit principle:

[0035] Connect the D6 pin of the closing coil HQ and the D7 pin of the contactor KM1 together to the closing + test terminal;

[0036] Connect the C8 pin of the closing coil HQ and the B3 pin of the contactor KM1 to the closing-test terminal;

[0037] Connect the trip coil C15 and the C12 pin of the trip contactor KM2 to the trip + test terminal;

[0038] Connect the trip coil D15 and the D12 pin of the trip contactor KM2 to the trip-test terminal;
