Description

Technical Field

[0001] This utility model relates to the field of junction boxes, specifically a sheet metal power junction box. Background Technology

[0002] In home renovation, junction boxes are one of the electrical accessories. Because the wires used in renovation run through conduits, junction boxes are used as transitions at the joints of the wires (such as when the wire is long or the conduit needs to turn a corner). The conduit connects to the junction box, and the wires inside the conduit are connected in the junction box, which serves to protect and connect the wires. This is what a junction box is.

[0003] After the wire is placed into the junction box, the end of the wire is fixed. However, because the height of the conduit and the junction box are different, there will be a height difference between the end of the wire and the wire body. This causes the end of the wire to be in a higher position, which will cause the wire body to be squeezed against the outer shell of the connecting device inside the junction box. This will cause indentations on the outer casing of the wire body. When the wire is vibrated or displaced, it may be damaged, making the wire unusable and reducing its lifespan.

[0004] Therefore, a sheet metal power junction box is proposed to address the above problems. Summary of the Invention

[0005] To overcome the shortcomings of existing technology and solve the problem that the wire end is located at a high position, causing the wire body to be squeezed against the outer shell of the connecting device inside the junction box, resulting in indentations on the outer casing of the wire body, and that the wire body may be damaged when the wire is vibrated or displaced, making the wire unusable and reducing its lifespan, this utility model proposes a sheet metal power junction box.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The sheet metal power junction box of this utility model includes a box body, a box cover abutting at the end of the box body, a connector fixedly connected inside the box body, and two protective components provided on the outside of the connector. The protective components include four sliders slidably connected inside the connector. The four sliders are divided into two groups. The ends of the two groups of sliders are fixedly connected to mounting blocks. The inside of the two groups of mounting blocks are fixedly connected to clamping members. The two clamping members are arranged opposite to each other. Rubber extensions are fixedly connected to the outside of the clamping members.

[0007] Preferably, the box body is provided with an auxiliary component, the auxiliary component including a limiting rod fixedly connected to the inside of the box body, the limiting rod passing through the mounting block and slidably connected, a first spring fixedly connected between the two clamping members, and a second spring fixedly connected between one of the clamping members and the box body.

[0008] Preferably, a pushing assembly is provided on the inner side of the box cover. The pushing assembly includes a slide cylinder fixedly connected to the inner side of the box cover. A slide rod is slidably connected inside the slide cylinder. The slide rod passes through the slide cylinder. A third spring is fixedly connected between the slide rod and the box cover.

[0009] Preferably, the pushing assembly further includes a pushing clamp fixedly connected to the end of the slide bar, and a transmission plate is slidably connected inside the pushing clamp.

[0010] Preferably, the transmission plate is slidably connected by a limiting rod, the outer side of the transmission plate is slidably connected to the inside of the box, and the outer side of the transmission plate is slidably connected to the outer side of the connecting piece.

[0011] Preferably, the rubber extension is set as a semi-circle, and the two rubber extensions combined form a circle.

[0012] Preferably, the elastic force of the first spring is less than that of the second spring, and the elastic force of the first spring is greater than that of the third spring.

[0013] The advantages of this utility model are: 1. This utility model uses the relative movement of two clamping members to clamp the wire body, and drives the two rubber extension members to clamp the wire body. This prevents the wire body from contacting the outside of the connector, thereby reducing the possibility of indentation caused by compression on the outer wrapping of the wire body, thus reducing the possibility of damage to the outer wrapping of the wire, ensuring the service life of the wire, and ultimately ensuring the safety of the wire in use.

[0014] 2. This utility model fixes the box cover to the outside of the box body, so that the push clamp pushes the transmission plate, thereby moving the transmission plate and pushing the clamping parts to move. When encountering a large-sized wire, the push clamp will be pushed in the opposite direction, thereby compressing the third spring, thereby causing the push clamp and the transmission plate to retract. This allows the distance between the two clamping parts to adapt to wires of different sizes, thus ensuring the adaptability of the device and enabling the device to accommodate more sizes of wires.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1-4 As shown, a sheet metal power junction box includes a box body 1, a box cover 2 abutting at one end of the box body 1, a connector 3 fixedly connected inside the box body 1, and two protective components provided on the outside of the connector 3. The protective components include four sliders 6 slidably connected inside the connector 3. The four sliders 6 are divided into two groups, and each of the two groups of sliders 6 has a mounting block 5 fixedly connected to its end. Each of the two groups of mounting blocks 5 has a clamping member 7 fixedly connected inside its interior. The two clamping members 7 are arranged opposite to each other, and a rubber extension 10 is fixedly connected to the outside of the clamping member 7.

[0020] During operation, the relative movement of the two clamping parts 7 clamps the wire body and drives the two rubber extension parts 10 to clamp the wire body, thus preventing the wire body from contacting the outside of the connector 3. This reduces the possibility of indentation caused by compression on the outer sheath of the wire body, thereby reducing the possibility of damage to the outer sheath of the wire, ensuring the service life of the wire, and ultimately ensuring the safety of the wire in use.

[0021] The box body 1 is equipped with an auxiliary component, which includes a limiting rod 4 fixedly connected inside the box body 1. The limiting rod 4 passes through the mounting block 5 and is slidably connected. A first spring 8 is fixedly connected between two clamping parts 7, and a second spring 9 is fixedly connected between one of the clamping parts 7 and the box body 1.

[0022] During operation, the cooperation of the first spring 8 and the second spring 9 prevents the two clamping parts 7 from clamping the wire too tightly, thus allowing the two clamping parts 7 to adapt to wires of different sizes, thereby improving the adaptability of the device and ensuring that the device can accommodate more sizes of wires.

[0023] The rubber extension 10 is set as a semi-circle, and the two rubber extensions 10 are combined to form a circle.

[0024] During operation, by setting the rubber extension 10 to a semi-circular shape, the rubber extension 10 can better wrap the wire, thereby ensuring the safety of the wire.

[0025] Among them, the elastic force of the first spring 8 is less than that of the second spring 9, and the elastic force of the first spring 8 is greater than that of the third spring 13.

[0026] During operation, the elastic force of the first spring 8, the second spring 9, and the third spring 13 is controlled to allow the device to better adapt to wires of different sizes, thereby improving the device's adaptability. Example

[0027] Please see Figure 5-6 As shown in the first embodiment, as another implementation of this utility model, a pushing component is provided on the inner side of the box cover 2. The pushing component includes a slide cylinder 11 fixedly connected to the inner side of the box cover 2. A slide rod 12 is slidably connected inside the slide cylinder 11. The slide rod 12 passes through the slide cylinder 11. A third spring 13 is fixedly connected between the slide rod 12 and the box cover 2.

[0028] The pushing assembly also includes a pushing clamp 14 fixedly connected to the end of the slide bar 12, and a transmission plate 15 is slidably connected inside the pushing clamp 14.

[0029] During operation, by fixing the cover 2 to the outside of the box body 1, the push clamp 14 pushes the transmission plate 15, thereby moving the transmission plate 15 and pushing the clamping member 7 to move. When encountering a large-sized wire, the push clamp 14 is pushed in the opposite direction, thereby compressing the third spring 13, thereby causing the push clamp 14 and the transmission plate 15 to retract. This allows the distance between the two clamping members 7 to accommodate wires of different sizes, thus ensuring the adaptability of the device and enabling the device to accommodate wires of more sizes.

[0030] The transmission plate 15 is slidably connected by the limiting rod 4, the outer side of the transmission plate 15 is slidably connected to the inside of the box 1, and the outer side of the transmission plate 15 is slidably connected to the outer side of the connecting piece 3.

[0031] During operation, the movement range of the transmission plate 15 is limited by the sliding connection between the transmission plate 15, the limit rod 4, and the box 1.

[0032] The working principle is as follows: by fixing the cover 2 to the outside of the box body 1, the push clamp 14 pushes the transmission plate 15, thereby moving the transmission plate 15 and pushing the clamping member 7 to move. When encountering a large wire, the push clamp 14 will be pushed in the opposite direction, thereby compressing the third spring 13, thereby causing the push clamp 14 and the transmission plate 15 to retract. This allows the distance between the two clamping members 7 to adapt to wires of different sizes, thus ensuring the adaptability of the device and enabling the device to accommodate more sizes of wires. The relative movement of the two clamping members 7 clamps the wire body and drives the two rubber extension members 10 to clamp the wire body, thus preventing the wire body from contacting the outside of the connector 3. This reduces the possibility of indentation caused by compression on the outer sheath of the wire body, thereby reducing the possibility of damage to the outer sheath of the wire, ensuring the service life of the wire, and ultimately ensuring the safety of the wire in use.
