A specific embodiment of the present invention discloses a modular power supply apparatus, as shown in fig. 1, including: a base 1, a socket 2 and a slide 4; wherein, one or more sockets 2 are arranged on the base 1; the socket 2 is used for being plugged with the plug 7; the socket 2 is provided with a metal sheet 6; after the plug 7 and the socket 2 are inserted in place, the metal sheet 6 is contacted with the contact of the plug 7 to realize electric connection. The sliding plate 4 is slidably mounted on the socket 2, i.e. the sliding plate 4 can slide relative to the socket 2, and an elastic element is arranged between the sliding plate 4 and the socket 2.

Under the action of external force, the sliding plate 4 can slide relative to the socket 2, so that a space for inserting the plug 7 and the socket 2 is formed, and meanwhile, the elastic piece is compressed; after external force is eliminated, the sliding plate 4 can reset under the elastic action of the elastic piece, and after the sliding plate 4 resets, the sliding plate can be used as a fastening piece to limit the displacement of the plug 7, so that the plug 7 is prevented from being inserted and loosened with the socket 2.

Further, as shown in fig. 2, the modular power supply apparatus of the present invention further includes: a slide cover plate 3.

Specifically, the structure of the skateboard deck 3 is shown in fig. 4.

In one embodiment of the present invention, the slide cover 3 is disposed above the slide 4 and is fixedly connected to the socket 2. Specifically, a first threaded hole 201 is formed in the socket 2, and a second threaded hole 302 is formed in the sliding plate cover plate 3; mounting screws in the first threaded hole 201 and the second threaded hole 302; the slide cover plate 3 is mounted on the socket by screws.

The slide cover 3 limits the slide 4 in the gap between the slide cover 3 and the receptacle 2, so that the slide 3 can only slide relative to the receptacle 2 without vertical displacement.

Specifically, the structure of the socket 2 is as shown in fig. 3.

Furthermore, a sliding plate guide groove 202 is arranged on the socket 2, and a convex sliding block 401 is arranged on the sliding plate 4; the slider 401 is slidably mounted in the sled guide groove 202. That is, the slider 401 slides in the slider guide groove 202, the slider 4 slides with respect to the receptacle 2.

Further, a plug slot 204 is arranged on the socket 2; the plug socket 204 is provided with a concave plug guide groove 206. When the plug 7 is plugged into the socket 2, the plug 7 is inserted into the plug slot 204, the plug guide slots 206 are symmetrically arranged on both sides of the plug slot 204, and the plug blocks are symmetrically arranged on both sides of the plugging portion of the plug 7, as shown in fig. 2; when the plug 7 is plugged, the plug block of the plug 7 slides along the plug guide groove 206, and the plugging process of the plug 7 is completed.

After the plug 7 is inserted in place, the insertion block of the plug 7 is matched with the plug guide groove 206, the plug guide groove 206 can block the plug 7 from moving back and forth, and the plug guide groove 206 can limit the plug 7 from sliding in the horizontal direction relative to the socket 2.

Further, the plug slots 204 are perpendicular to the sled guide grooves 202. That is, the direction in which the plug 7 is plugged into the receptacle 2 and the direction in which the slider 4 slides relative to the receptacle 2 are perpendicular to each other.

After the plug 7 is inserted into the plug slot 204, the sliding plate 4 prevents the plug 7 from sliding out of the plug slot 204 upwards, and the sliding plate 4 serves as a fastener to limit the displacement of the plug 7; i.e. the sledge 4 limits the sliding movement of the plug 7 in the vertical direction with respect to the socket 2.

In the compressed state of the slide 4:

2) as shown in fig. 7, the slide 4 is retracted into the inner cavity formed by the receptacle 2 and the slide cover 4. When the sliding plate 4 is in the compressed state, the plug 7 can be smoothly inserted into the plug slot 204. That is, during the insertion of the plug 7 into the socket 2, the slide 4 is compressed backward, so that the slide 4 compresses the elastic member, and the slide 4 is retracted between the slide cover 3 and the socket 2.

After the plug 7 is plugged, the plugging part of the plug 7 is lower than the sliding plate 4, the sliding plate 4 is popped up under the elastic force action of the spring 5, and the sliding plate 4 is reset and covers the plugging part of the plug 7 to limit the displacement of the plug 7.

Further, a metal piece insertion groove 203 is formed in the socket 2, and the metal piece insertion groove 203 is used for fixing the metal piece 6 for conducting electricity on the socket 2. The metal plate 6 is disposed in the metal plate insertion groove 203 to be connected in a plug-in manner.

Specifically, as shown in fig. 1 and 2, two sets of the metal sheet slots 203 and the metal sheets 6 are correspondingly arranged, so that the contact reliability of the plug 7 and the socket 2 is ensured.

Preferably, the metal sheet 6 is a copper metal sheet, which is inserted into the metal sheet slot 230 of the socket 2 while communicating with the power supply socket below the socket 2. The plug 7 and the socket 2 are mounted in a straight-inserting manner. After the plugging, the power supply jack is connected with the two metal sheets 6 on the socket 2, and the two metal sheets 6 on the socket 2 are connected with the two corresponding metal contact elements on the plug 7 to supply power for the power utilization module.

Furthermore, the copper sheet slot 203 is arranged below the sliding block 4, the socket 2 and the plug 7 form a mechanical structure, so that the copper sheet of the plug 7 is in close contact with the copper sheet of the socket, and the plugging part of the plug 7 is limited in the space formed by the sliding plate 4 and the socket 2.

Specifically, the structure of the slide 4 is as shown in fig. 5.

Further, a pusher 402 is provided above the slide 4.

Preferably, as shown in fig. 5, the shifting block 402 protrudes from the upper surface of the sliding plate 4, so as to switch the compression state and the ejection state of the sliding plate 4.

When the power supply module needs to be disconnected, the shifting block 402 is manually shifted backwards, the sliding plate 4 moves backwards to compress the spring 5, so that the plug 7 can slide relative to the socket 2, and the plug 7 is taken down.

Further, a groove 301 is formed in the sliding plate cover plate 3, and the groove 301 is used for avoiding the shifting block 402 when the sliding plate 4 slides. That is, the groove 301 is to pull the slide 4 without interference of the slider cover 3 with the slide 4.

Preferably, as shown in fig. 1, the base 1 of the modular power supply apparatus of the present invention is provided with four circumferentially symmetrical socket installation slots, the socket 2 is arranged in the socket installation slot, and the socket 2 is fixedly connected with the base 1. That is to say, a plurality of power supply modules can be arranged on the base 1 at the same time, so that power supply to a plurality of power utilization devices is realized at the same time.

Preferably, the socket 2 is connected with the base 1 through screws.

Further, in order to enhance the contact reliability of the plug 7 and the socket 2, a plurality of bumps having a diameter of less than 1mm are provided on the surface of the metal sheet 6. After the plug 7 is inserted into the socket 2, the metal sheet 6 is in a micro-compression state.

When in implementation:

first, the slide 4 of the device is pulled back along the slide guide groove 202 to compress the socket 2 of the device, and then the plug 7 is inserted to the bottom along the plug guide groove 206, and the slide 4 is released after confirming the installation, at which time the slide 4 slides out along the slide guide groove 202 under the action of the spring 5 and is stuck into the positioning groove in the plug 7 to prevent the plug from sliding out.
