Description

Technical Field

[0001] This utility model belongs to the field of power equipment installation technology, and in particular to an auxiliary tooling for the installation and positioning of a metering box. Background Technology

[0002] Currently, during the assembly of connectors for electricity metering boxes, it has been discovered that the positioning holes of the connectors are inaccurate. Due to positioning issues, misalignment is common, resulting in the connectors not being on the same level as the metering box window after the electricity meter is installed. Furthermore, the subsequent installation of the switch cover cannot be properly secured. During installation, testing, or maintenance, employees need to align the connectors with the screw holes and then drive them into the base shell with self-tapping screws. During the self-tapping screw driving process, the connectors are subject to the force of the electric screwdriver, causing them to shift. This shift results in misalignment of other screw holes, requiring readjustment. Employees must manually tighten the connectors to reduce this shifting, leading to quality problems, frequent rework, a lack of process control, and a significant impact on production efficiency.

[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0017] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0018] like Figures 1 to 5 The meter box installation and positioning auxiliary tooling shown includes a meter box bottom 1 for protecting the internal electrical components from the influence of the external environment. The meter box bottom 1 is usually made of metal (such as stainless steel, cold-rolled steel plate) or insulating material (such as engineering plastic), which has good mechanical strength and protective performance, and can be dustproof, waterproof and corrosion resistant, protecting the internal electrical components from the influence of the external environment. Common protection levels are IP54, IP65, etc. The meter box bottom 1 is provided with a tooling plate 2 to assist construction personnel in accurately determining the installation position of the meter box bottom 1. The tooling plate 2 has a handle 201 on its side for easy handling by the operator. The surface of the tooling plate 2 is provided with scale lines to provide a precise reference for installation and positioning. The bottom of the tooling plate 2 is provided with a clearance groove 202 to avoid parts. Using the handle 201, the tooling plate 2 is brought close to the inside of the bottom of the meter case 1 and placed in the designated position of the bottom of the meter case 1. Then, the connector 3 is placed into the bottom of the meter case 1. The bottom edge of the connector 3 contacts the top of the tooling plate 2. The clearance groove 202 can avoid the part position 4 and prevent the tooling plate 2 from affecting the parts.

[0019] The tooling plate 2 is equipped with connectors 3 for quick connection and positioning between components. Connectors 3 are used to connect external power lines and internal electrical components. They are mostly made of copper, which has good conductivity and connection stability, and facilitates the distribution of power input and output. A positioning frame 301 for auxiliary positioning of the meter box is welded on top of the connectors 3. Both the connectors 3 and the positioning frame 301 have multiple screw holes 101 for precise positioning of self-tapping screws. The bottom surface of the meter box shell 1 also has multiple screw holes 101 for fixing the connectors 3 and the positioning frame 301. Using self-tapping screws, the connectors 3 and the positioning frame 301 are fixed to the bottom surface of the meter box shell 1 through the screw holes 101. The tooling plate 2 supports the connectors, solving the problem of misalignment between the connectors 3 and the positioning frame 301, allowing employees to install them more quickly.

[0020] The vertical inner wall of the meter box bottom 1 is connected to a component storage compartment 4. The surface of the component storage compartment 4 slides in contact with the interior of the clearance groove 202. A door is installed on the side of the meter box bottom 1 to protect the internal components. The door prevents dust, moisture, foreign objects, etc. from entering the box, avoiding damage to electrical components due to external environmental factors, extending the service life of the meter box, ensuring the accuracy of power metering and the safe operation of the equipment. The meter box bottom 1 contains circuit breakers, fuses, contactors, etc. Circuit breakers are used to automatically disconnect the circuit when overload, short circuit, or other faults occur, protecting equipment and lines. Fuses melt and disconnect the circuit when the current is too high, providing short-circuit protection. Contactors are used to control the on / off state of the circuit, realizing the start and stop control of electrical equipment. This is not an innovative direction for the meter box installation and positioning auxiliary tooling, and will not be described in detail.

[0021] Working principle The meter box installation and positioning auxiliary tooling is used by first using the handle 201 to bring the tooling plate 2 close to the inside of the meter box bottom 1 and placing it in the designated position on the meter box bottom 1. Then, the connector 3 is placed into the meter box bottom 1, with the bottom edge of the connector 3 contacting the top of the tooling plate 2. Using self-tapping screws, the connector 3 and the positioning frame 301 are fixed to the meter box bottom 1 through the screw holes 101. The tooling plate 2 supports the connector, solving the problem of misalignment between the connector 3 and the positioning frame 301, allowing employees to install it more quickly. The clearance groove 202 can avoid the component position 4, preventing the tooling plate 2 from affecting the component.
