Description

Technical Field

[0001] The utility model relates to the field of electrical control switches, in particular to an optimized structure of a four-pin industrial socket strip. Background Art

[0002] At present, the four-pin industrial socket shell used is equipped with L1 conductive copper strip, L2 conductive copper strip, L3 conductive copper strip, neutral conductive copper strip and ground conductive copper strip, and L1 conductive copper strip, L2 conductive copper strip, L3 conductive copper strip, neutral conductive copper strip and ground conductive copper strip are arranged in parallel in the lower shell. Fig.11 As shown: Among them, the L1 conductive copper bar is installed above the L2 conductive copper bar, the L3 conductive copper bar is installed above the L2 conductive copper bar, and the ground conductive copper bar is installed above the L3 conductive copper bar, and then each copper bar is connected to the jumper copper bar led out from the corresponding conductive clip. With this structural arrangement, sufficient space is required in the lower shell of the socket strip to arrange the conductive copper bars, which makes the volume inside the socket strip too large and increases the material production cost.

[0003] At the same time, the five-hole jack area on the upper shell of the socket strip is arranged above the four-hole jack area. Adopting this structure will also cause the wiring head of the plug inserted into the five-hole jack area to bend when the plug is inserted into the five-hole jack area because there is a plug inserted in the four-hole jack area. The long-term bending will cause the plug wire to be damaged, and there will be safety hazards such as leakage during use. Summary of the invention

DETAILED DESCRIPTION

[0035] Specific implementation method 1: Combination Figure 1 and Figure 3 The present embodiment is described as an optimized structure of a four-pin industrial power strip, which comprises an upper shell 1 and a lower shell 2, which are buckled and connected with each other, and a group of conductive components 3 are installed on the lower shell 2, and each group of conductive components comprises a first conductive clip 3-1, a second conductive clip 3-2, a third conductive clip 3-3 and a ground conductive clip 3-4;

[0036] There are mounting columns between the first conductive clip 3-1, the second conductive clip 3-2, the third conductive clip 3-3 and the ground conductive clip 3-4. After the mounting columns on the lower shell are aligned with the mounting columns on the upper shell, bolts are passed through the bottom of the lower shell to fix the upper shell and the lower shell together.

[0037] The four conductive clips, namely the first conductive clip 3-1, the second conductive clip 3-2, the third conductive clip 3-3 and the ground wire conductive clip 3-4, have the same structure and are made of copper. Each conductive clip has a wavy structure and has a mounting plate on it. The mounting plate and the conductive clip are connected as an integral structure. The mounting plate is a rectangular copper plate structure and has mounting holes on it. The conductive clip can be fixed on the conductive copper bar through the mounting plate.

[0038] The bottom of the lower shell 2 is provided with a group of conductive copper strip slots 4, a group of short jumper conductive sheet slots 5 and a group of long jumper conductive sheet slots 6. The group of conductive copper strip slots 4 is provided with conductive copper strips, and the conductive copper strips include L1 conductive copper strips 7, L2 conductive copper strips 8, L3 conductive copper strips 9, neutral conductive copper strips 10 and ground conductive copper strips 11. The L2 conductive copper strips 8 are provided below the L3 conductive copper strips 9, and the L1 conductive copper strips 7 are provided below the L2 conductive copper strips 8. The group of short jumper conductive sheet slots 5 is provided with short jumper conductive sheets 12, and the group of long jumper conductive sheet slots 6 is provided with long jumper conductive sheets 13.

[0039] The groove width and groove length of the conductive copper strip slot are slightly larger than the length and width of each group of corresponding conductive copper strips, so that the conductive copper strip can be inserted into the conductive copper strip slot. When the corresponding conductive copper strip is inserted into the conductive copper strip slot, the mounting holes on the corresponding conductive copper strip and the mounting holes on the lower shell are connected by bolts to fix the conductive copper strip in the corresponding conductive copper strip slot, so that the conductive copper strip and the lower shell form an integrated structure.

[0040] The upper part of the ground wire conductive copper strip 11 is fixedly connected to the mounting plate 18 of the ground wire conductive clip 3-4;

[0041] The ground wire conductive clips 3 - 4 are arranged longitudinally above the ground wire conductive copper strip, and the ends of the ground wire conductive copper strip are connected to the cover.

[0042] The upper part of the L3 conductive copper strip 9 is fixedly connected to the mounting plate 18 on the third conductive clip 3 - 3 ;

[0043] The third conductive clip 3 - 3 is arranged horizontally above the L3 conductive copper strip, and the end of the L3 conductive copper strip is connected to the cover.

[0045] The L2 conductive copper strip 8 is fixedly connected to one end of a group of short jumper conductive sheets 12, and the other end of the short jumper conductive sheet 12 is fixedly connected to the mounting plate 18 of the second conductive clip 3-2;

[0046] The upper shell 1 has a group of four-hole jack areas 14, a two-hole jack area 15 and a five-hole jack area 16, wherein the two-hole jack area 15 and the five-hole jack area 16 can be arranged above the upper shell 1 or on the upper side of the upper shell 1, and the five-hole jack area 16 is arranged between two adjacent four-hole jack areas 14.

[0047] The five-hole jack area can be set in the middle position or near the top position of two adjacent four-hole jack areas. Setting the five-hole jack area between two adjacent four-hole jack areas can prevent the power cord of the plug from bending when the plug is inserted into the five-hole jack area, so that the power cord of the five-hole jack area can extend through between the two adjacent four-hole jack areas, preventing the wiring of the plug from bending.

[0048] Specific implementation method three: Combination Figure 4 , Figure 5 The present embodiment is described as an optimized structure of a four-pin industrial power strip, wherein the L1 conductive copper bar, the L2 conductive copper bar, the L3 conductive copper bar, the neutral conductive copper bar and the ground conductive copper bar are of different lengths and are arranged in a parallel structure.

[0049] The L1 conductive copper bar, L2 conductive copper bar, L3 conductive copper bar, neutral line conductive copper bar and ground line conductive copper bar are rectangular structures, and the L3 conductive copper bar and ground line conductive copper bar are arranged on both sides of the conductive component, and the corresponding conductive clips composed of the conductive component are arranged above the L3 conductive copper bar and the ground line conductive copper bar, thereby reducing the space of the lower shell and reducing the material cost.

[0050] Specific implementation method four: Combination Figure 2 or Fig.10 To illustrate this embodiment, a group of the long-bridge conductive sheets and a group of the short-bridge conductive sheets are arranged in a parallel structure.

[0051] The short jumper conductive sheet slot 5 and the long jumper conductive sheet slot 6 have the same slot depth, and the depth of the short jumper conductive sheet slot 5 and the long jumper conductive sheet slot 6 is greater than the depth of the conductive copper strip slot 4, so that the short jumper conductive sheet 12 and the long jumper conductive sheet 13 installed in the slot body are arranged below the conductive copper strip.

[0052] The overall structure of the short jumper conductive sheet and the long jumper conductive sheet is the same, the slot width of the long jumper conductive sheet slot and the short jumper conductive sheet slot are the same, and the slot lengths are different, wherein the bending portion of the short jumper conductive sheet is set in a shallow slot, and a mounting hole is opened at the bending portion of the short jumper conductive sheet, and screws are installed in the mounting hole to fix the short jumper conductive sheet in the short jumper conductive sheet slot. Similarly, the bending portion of the long jumper conductive sheet is set in a shallow slot, and a mounting hole is opened at the bending portion of the long jumper conductive sheet, and screws are installed in the mounting hole to fix the long jumper conductive sheet in the long jumper conductive sheet slot.

[0053] The short jumper conductive sheet 12 and the long jumper conductive sheet 13 have different lengths and the tops are symmetrical structures bent at 90 degrees.

[0054] The short-bridge conductive sheet 12 and the long-bridge conductive sheet 13 are arranged in a bridge structure below a group of conductive copper bars, so that a group of long-bridge conductive sheets and a group of short-bridge conductive sheets and the conductive copper bars form a staggered structure arrangement, saving the arrangement space inside the lower housing.

[0056] The first conductive clip 3-1, the second conductive clip 3-2, the third conductive clip 3-3 and the ground conductive clip 3-4 correspond to the sockets corresponding to the four-hole socket area on the upper shell. When the plug is inserted into the four-hole socket area on the shell, the plug contacts the first conductive clip 3-1, the second conductive clip 3-2, the third conductive clip 3-3 and the ground conductive clip 3-4, so that power is transmitted to the plug.

[0057] Specific implementation method six: Combination Figure 5 or Fig.10 To illustrate this embodiment, the third conductive clip 3 - 3 described in this embodiment is arranged vertically between the first conductive clip 3 - 1 , the second conductive clip 3 - 2 and the ground conductive clip 3 - 4 .

[0060] The sealing covers correspond to each conductive copper strip respectively, and the sealing covers are buckled at the card slots. At the same time, the power cords of the strip are pressed and buckled at the sealing covers through wires. After the power cords on the strip are inserted into the sealing covers respectively, the sealing covers are connected to the conductive copper strips, so that the points are sent to each conductive clip through the conductive copper strips.

[0062] The apertures of the screw mounting holes on the L1 conductive copper bar 7, L2 conductive copper bar 8, L3 conductive copper bar 9, neutral line conductive copper bar 10 and ground line conductive copper bar 11 are the same, and the screw mounting holes on the L1 conductive copper bar 7, L2 conductive copper bar 8, L3 conductive copper bar 9, neutral line conductive copper bar 10 and ground line conductive copper bar 11 are respectively aligned with the hole positions on the lower shell body. After alignment, the screws are respectively passed through the mounting holes on the conductive copper bars, so that the L1 conductive copper bar 7, L2 conductive copper bar 8, L3 conductive copper bar 9, neutral line conductive copper bar 10 and ground line conductive copper bar 11 are respectively fixed in the lower shell body by the screws.

[0063] The original L3 conductive copper strip 9 and the ground conductive copper strip 11 are arranged on both sides of the socket, and the second conductive clip 3-2 is arranged in the same direction as the first conductive clip 3-1 and the ground conductive clip 3-4. A group of third conductive clips 3-3 are installed above the L3 conductive copper strip 9, and the mounting plate 18 on the third conductive clip 3-3 is fixedly connected to the L3 conductive copper strip 9 by screws. At the same time, a mounting plate of a group of ground conductive clips 3-4 is arranged on the ground conductive copper strip 11 and fixedly connected.
