Description

Technical Field

[0001] The utility model relates to an inverter power supply, in particular to an inverter power supply for an AC / DC integrated power supply system, belonging to the technical field of power supply systems. Background Art

[0002] In the prior art, for example, a utility model with application number 202322395781.6 discloses an inverter power supply. In order to solve the problem that the cable connector is easily detached from the inverter power supply connector, causing the connection between the cable connector and the inverter power supply connector to become loose, which may lead to poor contact at the connection between the cable connector and the inverter power supply connector and affect the use of the inverter power supply, an anti-detachment mechanism is added to one side of the connector of the inverter power supply body. After the cable terminal is connected to the inverter power supply body connector, the straight rod is rotated so that the arc rod is buckled at the end of the terminal to limit the position of the terminal to prevent it from falling off the connector and affecting the use of the inverter power supply body.

[0003] Similar to the above application, there are still some shortcomings:

[0004] After the cable terminal and the connector are plugged in, the anti-dropping mechanism needs to be manually controlled to be clamped and closed. Due to the small size and parts of the anti-dropping mechanism, manual control is inconvenient and affects the operation;

[0005] Therefore, an AC / DC integrated power supply system is designed to optimize the above problems using an inverter power supply. Utility Model Content

However, the implementation manners of the present utility model are not limited thereto.

[0023] As Figures 1 - 4 shown, this embodiment provides an inverter power supply for an AC-DC integrated power supply system, including an inverter power supply body 1, a power supply connector 2 installed at the rear end of the inverter power supply body 1, an input jack 3 provided on the side of the power supply connector 2, and a cable terminal 4 inserted into the input jack 3. Slide grooves 5 are symmetrically provided on both sides of the input jack 3, slide blocks 6 are slidably installed inside the slide grooves 5, first springs 7 are provided between the ends of the slide grooves 5 away from the input jack 3 and the slide blocks 6, side plates 9 are symmetrically provided on both sides of the input jack 3, and the side plates 9 are respectively fixed on the slide blocks 6. The ends of the side plates 9 away from the slide blocks 6 are inclined towards the input jack 3, and pressure plates 10 are inclined towards the input jack 3 at the ends of the side plates 9 away from the slide blocks 6.

[0024] Overall working principle: When the cable terminal 4 is aligned with the input jack 3 and inserted, since the two pressure plates 10 at the front end of the input jack 3 are in contact with each other and inclined towards the input jack 3, forming a V-shaped notch, when the cable terminal 4 is inserted, it will push the pressure plates 10 outwards, control the slide block 6 to slide inside the slide groove 5, and compress the first spring 7. After the cable terminal 4 is completely inserted into the input jack 3, the pressure plates 10 slide out from the side of the cable terminal 4 and get stuck on the end face of the cable terminal 4 to stabilize the position of the cable terminal 4.

[0025] In this embodiment, the sides of the two groups of pressing plates 10 on both sides of the input jack 3 are in contact with each other, and arc-shaped grooves are formed on the sides of the pressing plates 10 .

[0026] Partial working principle: By opening an arc-shaped groove on the pressure plate 10, it can be clamped on the outside of the cable after being separated from the side of the cable terminal 4, which has higher stability.

[0027] In this embodiment, the side plate 9 and the pressing plate 10 are integrally injection-molded, and the outer surface of the pressing plate 10 is smooth.

[0028] Local working principle: the strength of the side plate 9 and the pressure plate 10 is ensured, and the production is more convenient.

[0029] In this embodiment, a shield 8 is fixed on each of the sliders 6 , and the shield 8 is attached to the end surface of the inverter power supply body 1 and covers the outer side of the input jack 3 .

[0030] Partial working principle: Due to the use of the shield 8, in the initial state, the input jack 3 can be directly shielded to effectively prevent dust. When the pressure plate 10 is opened, it moves with the slider 6 and is stuck on the side of the cable terminal 4 to increase stability.

[0031] In this embodiment, a semicircular groove 11 is provided on the shielding plate 8, a hidden groove 12 is provided on the inner side of the semicircular groove 11, a dustproof plate 13 is slidably provided inside the hidden groove 12, and the dustproof plate 13 covers the semicircular groove 11, and a second spring 14 is provided between the inner end of the hidden groove 12 and the dustproof plate 13.

[0032] Local working principle: In order to ensure that the pressure plate 10 can fit on the side of the cable after being clamped on the end of the cable terminal 4, a dustproof plate 13 that can slide on the baffle plate 8 can be moved a distance toward the inside of the baffle plate 8 when clamped, ensuring that the dustproof plate 13 fits on the side of the cable terminal 4, and the pressure plate 10 can be closed on the outside of the cable on the cable terminal 4, thereby improving the stability of the plug-in.

[0033] In this embodiment, a sealing strip is disposed on one side of the dustproof plate 13 away from the second spring 14 , and the length of the sealing strip is the same as the diameter of the dustproof plate 13 .

[0034] Partial working principle: The use of the sealing strip can ensure the sealing effect of the dustproof plates 13 on the input jack 3 when the dustproof plates 13 are in close contact with each other in the initial state.
