Description

Technical Field

[0001] This utility model relates to the field of branching device technology, specifically to a power transmission line branching device. Background Technology

[0002] In routine meter installation, wiring, and minor electrical repairs, as well as in the electrical appliances used in every household, such as sockets and switches, these components all require electrical wires to transmit power, ensuring that electricity remains an indispensable necessity for every family. The wiring distribution device, through a splitter within its housing, performs the branching operation. By tightly securing the splitter to the copper contacts and screws in the wires, it effectively branches the main circuit into multiple sub-circuits.

[0003] The existing technology has the following problems:

[0004] In current power transmission line branching devices, the installation process involves using crimping pliers to fix the copper connectors to the power lines, and then connecting the connectors to the branch unit using screws. However, in actual use, it is cumbersome to tighten the screws on the copper connectors of the main power line and branch lines one by one with a screwdriver. Furthermore, because the screws are small, they are easily lost during use, making them difficult to find and affecting the wire connection. This prevents the main power line and branch lines from quickly connecting to the branch unit, resulting in low connection efficiency. In addition, existing branch units are not convenient to use when open, causing inconvenience for later maintenance and inspection.

[0005] Therefore, we need a power transmission line branching device to solve the above problems. Utility Model Content

[0013] A further improvement of this utility model is that the inside of the limiting groove is in corresponding contact with the outer surface of the upper and lower limiting plates, and the front and rear sides of the wiring copper block are in corresponding contact with the inner side of the U-shaped plate.

[0014] A further improvement of this utility model is that the connecting component includes an L-shaped elastic plate and a mounting block. The horizontal outer surface of the L-shaped elastic plate is fixedly connected to the surface of the base, and the surface of the mounting block is fixedly connected to the surface of the cover. The vertical rear side of the L-shaped elastic plate is fixedly connected with locking blocks at both the top and bottom. The locking blocks at the top and bottom are right-angled triangular blocks. The front side of the mounting block has blocking grooves at the top and bottom. The shape of the blocking grooves is the same as that of the locking blocks, and the interior of the blocking grooves corresponds to the outer surface of the locking blocks.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1: As Figures 1 to 6 As shown, this utility model provides a power transmission line branching device, including a base 1 and a cover 2. The base 1 serves as the basic support component of the entire device, providing a stable installation platform for each conductive component and wiring structure. The cover 2 is used to protect the components in the base 1. The rear side of the base 1 is movably connected to the rear side of the cover 2. This connection method allows the cover 2 to be flipped around the rear connection point, making it convenient for staff to open the cover 2 for later maintenance and inspection.

[0027] A connecting component 3 is installed on the front of the base 1 and the cover 2 to limit the cover 2 to the base 1 after it is closed, so as to prevent the cover 2 from being opened accidentally.

[0028] Example 2: Figures 1 to 6 As shown, the connecting component 3 includes an L-shaped elastic plate 31 and a mounting block 32. The outer surface of the L-shaped elastic plate 31 is fixedly connected to the surface of the base 1 in the horizontal direction, and the material of the L-shaped elastic plate 31 is plastic, which has good elastic deformation ability. The surface of the mounting block 32 is fixedly connected to the surface of the cover 2. A locking block 33 is fixedly connected to the upper and lower sides of the vertical rear side of the L-shaped elastic plate 31. The locking block 33 is a right-angled triangular block. The upper and lower sides of the front of the mounting block 32 are provided with blocking grooves, and the shape of the blocking grooves is the same as that of the locking block 33. When the cover 2 is closed, the mounting block 32 squeezes the locking block 33, causing the L-shaped elastic plate 31 to deform and bend. 2. After being fully closed, the bent L-shaped elastic plate 31 returns to its original position, and the locking block 33 will be locked into the blocking groove. The limiting is achieved by utilizing the structural characteristics of the right-angled triangular block. A groove 34 is provided on the rear side of the upper surface of the mounting block 32. A connecting rod is fixedly connected to the upper part of the middle of the rear side of the vertical direction of the L-shaped elastic plate 31. A cam 35 is movably connected through the outer surface of the connecting rod. The outer surface of the cam 35 corresponds to the inside of the groove 34. When the locking block 33 is locked into the blocking groove, the cam 35 is rotated to lock it into the groove 34, which can further enhance the connection stability between the L-shaped elastic plate 31 and the mounting block 32, so that the L-shaped elastic plate 31 has a locked state on the mounting block 32.

[0029] Example 3: Figures 1 to 6As shown, a main line port 4 is provided in the lower left center of the cover 2 for inserting the copper connector 51. The main line port 4 is equipped with a main wire 5. The front and rear sides of the lower right side of the cover 2 are provided with branch line ports 6 for inserting the copper connector 51 in the branch wires 7. The front and rear branch line ports 6 are equipped with branch wires 7. The outer surfaces of the main wire 5 and the two branch wires 7 are all equipped with copper connectors 51. The upper surface of the copper connector 51 is provided with a limiting groove 52 for cooperating with the limiting plate 122 in the main line quick-connect assembly 12 and the branch line quick-connect assembly 13 to position the copper connector 51 and prevent it from falling out of position inside the device. The right end of the copper connector 51 is provided with a V-shaped surface 53, which can better fit and squeeze with the inclined surface 123 in the upper and lower limiting plates 122 during installation.

[0030] T-shaped copper plates 11 are fixedly connected to the front and rear sides of the left side of the upper surface of the base 1. These plates are the main conductive carriers inside the device and are made of copper, which can effectively transmit current. The T-shaped structure can simultaneously connect the main line quick-connect assembly 12 and the branch line quick-connect assembly 13, realizing current conduction between the main line and the branch line. The main line quick-connect assembly 12 is fixed to the front and rear horizontal surfaces of the two T-shaped copper plates 11 to fix the connecting copper block 51 on the main wire 5. The branch line quick-connect assembly 13 is fixed to the left and right horizontal sides of the two T-shaped copper plates 11 to fix the connecting copper block 51 on the branch line 7. The main line quick-connect assembly 12 and the branch line quick-connect assembly 13 have the same structure. In addition, the two limiting plates 122 and the U-shaped plate 121 in the main line quick-connect assembly 12 and the branch line quick-connect assembly 13 are made of copper.

[0031] A sleeve is fixed to the center of the end face of the copper connector 51. The sleeve is designed to facilitate the insertion of the copper wire from the electrical wire into it. Subsequently, the worker can use crimping pliers to firmly fix the sleeve to the copper connector 51, thereby achieving an effective connection between the electrical wire and the copper connector 51.

[0032] Example 4: Figures 1 to 6As shown, the main quick-connect assembly 12 includes a U-shaped plate 121. Two limiting plates 122 are provided on the inner side of the U-shaped plate 121. The lower surface of the lower limiting plate 122 is fixedly connected to the surface of the base 1. Two inclined surfaces 123 are mirror-imagely arranged on the left side of the opposite surfaces of the upper and lower limiting plates 122, forming a V-shape. These inclined surfaces 123 cooperate with the V-shaped surface 53 in the wiring copper block 51, guiding the wiring copper block 51 accurately into the space between the two limiting plates 122. Fixing rods 124 are fixed to the front and rear of the upper surface of the upper limiting plate 122. Their outer surfaces penetrate the outside of the U-shaped plate 121 and are slidably connected to it, providing guidance for the up-and-down movement of the upper limiting plate 122 and preventing it from tilting during movement. A spring 125 is sleeved below the outer surface of the fixing rod 124, providing… The elastic reset function allows the upper limit plate 122 to be pushed back to its original position by the spring 125 after the upper limit plate 122 moves upward, so that the upper and lower limit plates 122 are in a combined state. At this time, the upper and lower limit plates 122 enter the limit groove 52. A cylindrical handle 126 is fixed in the middle of the upper surface of the upper limit plate 122, and its outer surface penetrates the outside of the U-shaped plate 121 and is slidably connected to it. The operator can pull the cylindrical handle 126 to move the upper limit plate 122 up and down, which facilitates the removal of the wiring copper block 51. A blocking strip 127 is fixed on the upper right side of the upper limit plate 122 to prevent the wiring copper block 51 from separating from the upper limit plate 122. In addition, the upper end of the spring 125 is fixed to the surface of the U-shaped plate 121, and the lower end is fixed to the surface of the upper limit plate 122.

[0033] Working principle: In actual operation, the worker first removes a small portion of the insulation from the main wire 5. Then, the copper wire from the main wire 5 is inserted into the sleeve of the connecting copper block 51. Next, the worker uses crimping pliers to fix the sleeve of the connecting copper block 51 to the copper wire. The worker then repeats the above steps to install the connecting copper blocks 51 in the two branch wires 7. After installation, the worker inserts the connecting copper blocks 51 into the main wire port 4. During insertion, the V-shaped surface 53 and the upper and lower inclined surfaces 123 contact and correspond, thereby squeezing the upper limiting plate 122 and moving it upward to drive the spring 125 to contract. When the connecting copper block 51 is inserted into the appropriate position, the spring 125 resets and drives the upper limiting plate 122 to move downward, causing the two limiting plates 122 to close and enter the interior of the limiting groove 52, realizing the quick installation of the main wire 5 and the branch. The installation steps of the two branch wires 7 and the branch quick-installation assembly 13 are the same as those of the main wire quick-installation assembly 12.

[0034] The worker shuts off the power switch and rotates the cam 35 to the appropriate position. The worker then moves the L-shaped elastic plate 31 vertically, causing it to deform and bend. At this point, the locking block 33 separates from the blocking groove in the mounting block 32. The worker then flips the cover 2 to open it. The worker then pulls the cylindrical handle 126 upwards, causing the upper limit plate 122 to move and the spring 125 to retract, thus removing the wiring copper block 51. This facilitates the inspection and maintenance of the upper surface structure in the base 1.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
