Description

Technical Field

[0001] The utility model relates to the technical field of voltage monitoring, in particular to a fixed buffer mechanism and a terminal row monitoring set. Background Art

[0002] In the electric power industry, control circuits generally use a DC 24V power supply. For example, signal collection and transmission, and command issuance all use a DC 24V power supply. When the voltage is too high, it may damage the relay coil or local automation components. When the voltage is too low, the relay may not operate normally or the collected signal data may be distorted. Therefore, monitoring the 24V power supply is particularly important.

[0003] At present, the monitoring of 24V power supply is mostly to monitor the voltage, but lacks the monitoring of the specific value of the voltage. The voltage can only be measured manually at the output end of the switching power supply with a multimeter, which is not intuitive and convenient. If the power module fails, the output voltage is obviously too high or too low, which is difficult to find in time during the inspection. In some cases, technicians use temporary connection of voltmeters for measurement. Although it can provide simple data detection, the connection of the voltmeter is unstable and it is easy to fail when exposed to the external environment. In addition, factors such as wind, sand, water, and collision will affect its work.

[0004] Therefore, there is a need for a fixed buffer mechanism and terminal block monitoring kit that can provide buffering and anti-seismic functions, can effectively avoid wind and sand, and can bring efficient and intuitive voltage monitoring effects to meet the needs of the existing environment. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0006] In view of the use of temporary connection voltmeter for measurement, although it can provide simple data detection, the voltmeter connection is unstable and it is easy to malfunction when exposed to the external environment. In addition, factors such as wind, sand, water, and collision will affect its operation.

[0014] The fixed buffer mechanism in the utility model has the following beneficial effects: it is very simple to disassemble and start up; the expansion of the buffer airbag can not only provide a buffer and anti-vibration function, but also the airbag is made of rubber material, which can avoid wind, sand and water seepage; the expansion of the buffer airbag will not clamp the insertion end; only the adjustment knobs on both sides of the insertion end need to be rotated to release the limit and take out the insertion end for easy maintenance.

[0015] In view of the fact that the current monitoring of 24V power supply is mostly to monitor the presence or absence of voltage, and lacks monitoring of the specific voltage value, the voltage can only be measured manually at the output end of the switching power supply with a multimeter, which is not intuitive and convenient.

[0031] Example 1

[0032] Reference Figures 1-2 , which is the first embodiment of the utility model, and this embodiment provides a fixed buffer mechanism.

[0033] The clamping assembly 100 is used to effectively fix and clamp the external insertion terminal 104 or other voltage measuring components. All structures are located in the matching assembly 101. The front end of the matching assembly 101 is fixedly provided with a storage cavity 102. The insertion terminal 104 or other voltage measuring components are installed in the storage cavity 102. The inner wall of the storage cavity 102 is fixedly provided with two symmetrical positioning grooves 103. The positioning grooves 103 can be used to assist in fixing the insertion terminal 104. The back side of the insertion terminal 104 is fixedly provided with an extension that can correspond to the positioning groove 103. The insertion terminal 104 can be directly inserted and matched with the positioning groove 103.

[0034] The buffer assembly 200 can provide buffer protection for the insertion end 104. A pneumatic unit 201 is fixedly arranged in the positioning groove 103. The pneumatic unit 201 can be activated when the insertion end 104 is gradually inserted into the positioning groove 103, and the pneumatic unit 201 can input air pressure to the other end of the pneumatic unit 201. The buffer airbag 202 is fixed at the four walls of the storage cavity 102, and the buffer airbag 202 is connected with the pneumatic unit 201. The output of the pneumatic unit 201 will drive the buffer airbag 202 to expand. The expanded buffer airbag 202 can fill the gap between the insertion end 104 and the storage cavity 102 after the insertion of the insertion end 104. The buffer airbag 202 itself is made of soft rubber material. While providing buffering and shockproof functions, it can also have a certain barrier effect on external wind and sand and impurities. It can not only protect the electronic components such as the insertion end 104 from physical collision, but also prevent wind and sand impurities, water seepage, etc. from causing harm to the equipment.

[0035] The connection assembly 300 is used to connect the electronic components such as the insertion terminal 104 and the matching assembly 101 itself, and can realize voltage monitoring of the matching assembly 101 itself and the surrounding terminal rows. The inner wall of the storage cavity 102 is also fixedly provided with a transmission hole 301, which can be located between the two positioning grooves 103. The back of the insertion terminal 104 itself is provided with a wire, which can pass through the transmission hole 301 and enter the inside of the matching assembly 101.

[0036] A wiring groove 302 is also horizontally arranged on the inner wall of the mating assembly 101. The wiring groove 302 itself is made of metal. While accommodating the wires, by welding the wires arranged on the back of the insertion terminal 104 itself to the wiring groove 302, the insertion terminal 104 can be used to monitor and read whether the voltage of the mating assembly 101 and the surrounding terminal blocks meets the regulations.

[0037] Example 2

[0038] Reference Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, but differs in that the structure of the storage component 100 and the matching structure of the operating component 200 are further optimized.

[0039] Adjustment knobs 104a are rotatably provided on both sides of the insertion end 104, and a matching rod 104a-1 is fixedly provided on the other end of the adjustment knob 104a. The matching rod 104a-1 passes through the insertion end 104 itself and is located on the back side of the insertion end 104. The matching rod 104a-1 can be driven to rotate by rotating the adjustment knob 104a. The matching rod 104a-1 is used to be matched and plugged with the positioning groove 103. When the insertion end 104 gradually enters along the receiving cavity 102, the matching rod 104a-1 enters the positioning groove 103.

[0040] The inner wall of the storage cavity 102 is fixedly provided with a snap-on unit 102a, which can fit in the positioning groove 103. A groove 102b is fixedly provided on the inner wall of the snap-on unit 102a, and the other end of the groove 102b is connected to the positioning groove 103, and a limiting marble 102a-1 is provided in the groove 102b, and the limiting marble 102a-1 is elastically connected to the bottom of the inner wall of the groove 102b, and the other end of the limiting marble 102a-1 is located in the positioning groove 103, and the limiting marble 102a-1 itself is made of a smooth material.

[0041] The outer wall of the matching rod 104a-1 is fixed with a snap-in hole 104a-2. When the matching rod 104a-1 begins to enter the positioning groove 103, the matching rod 104a-1 will begin to contact the limiting marble 102a-1, pushing the limiting marble 102a-1 to gradually enter the groove 102b, ensuring that the movement path of the matching rod 104a-1 is not affected. When the snap-in hole 104a-2 begins to correspond to the groove 102b, the matching rod 104a-1 can no longer push the limiting marble 102a-1, and the limiting marble 102a-1 will enter the snap-in hole 104a-2 under the action of the elastic force, thereby playing a limiting and locking role on the matching rod 104a-1.

[0042] A piston 203 is slidably disposed in the positioning groove 103, and the piston 203 itself is located on one side of the limiting marble 102a-1. When the limiting marble 102a-1 gradually enters the groove 102b, the matching rod 104a-1 will also push the piston 203 to move at the same time. The piston 203 and the inner wall of the positioning groove 103 are tightly fitted to ensure stable air pressure. A spring 203a is fixedly disposed at one end of the piston 203, and the other end of the spring 203a is fixedly connected to the bottom of the positioning groove 103. The spring 203a itself has a small elastic force and will not affect the matching of the limiting marble 102a-1 and the clamping hole 104a-2.

[0043] The inner wall of the storage cavity 102 is provided with an air guide tube 204, one end of which is connected to the positioning groove 103, and the other end is connected to the buffer airbag 202. When the piston 203 is pushed by the matching rod 104a-1, it will deliver air pressure to the air guide tube 204 and the buffer airbag 202, so that the buffer airbag 202 will expand synchronously. When the matching rod 104a-1 is finally stuck by the limit marble 102a-1, it is the maximum movement stroke, the buffer airbag 202 expands to the maximum, and the insertion end 104 is fixed. When it is necessary to temporarily remove the insertion end 104, it is only necessary to manually rotate the adjustment knob 104a to drive the matching rod 104a-1 to rotate. When the matching rod 104a-1 rotates, the limit marble 102a-1 can be squeezed into the groove 102b again. Without the fixation of the limit marble 102a-1, the insertion end 104 can be taken out for maintenance and debugging.

[0046] A wire reel 104b is fixedly provided on the back of the insertion end 104, and a connecting wire 303 is fixedly provided on the wire reel 104b. The transmission hole 301 can be located between the two positioning grooves 103. The connecting wire 303 is provided on the back of the insertion end 104 itself, and the connecting wire 303 can be passed through the transmission hole 301 and enter the interior of the mating assembly 101.

[0047] A wiring groove 302 is also horizontally arranged on the inner wall of the mating assembly 101. The wiring groove 302 itself is made of metal. While accommodating the wires, by welding the connecting wire 303 arranged on the back of the insertion terminal 104 itself to the wiring groove 302, the insertion terminal 104 can be used to monitor and read whether the voltage of the mating assembly 101 and the surrounding terminal blocks meets the regulations.

[0048] A fastening groove 304 is fixedly provided on the top of the mating assembly 101. The fastening groove 304 is located above the wiring groove 302 and is connected to the wiring groove 302. The fastening groove 304 can be used to cooperate with a pin, a screw, etc. to secure the wires in the wiring groove 302.
