Description

Technical Field

[0001] The invention relates to the field of electric energy meters, and in particular to a detachable anti-drop terminal button box and a use method thereof. Background Art

[0002] With the continuous advancement and simplification of electricity meter installation technology, more and more countries and regions have put forward the demand to prevent the locking screws from falling off during the installation process.

[0003] At present, most of the existing terminal boxes can only prevent the locking screws from falling off, but cannot normally remove the damaged screws. Once the screws fail, on the one hand, the entire meter needs to be dismantled and repaired during the production process, which increases the production cost of the energy meter; on the other hand, after it is put into operation, the energy meter will be scrapped because the screws cannot be replaced, which increases the product operation and maintenance cost. Summary of the invention

[0004] The purpose of the present invention is to provide a detachable anti-drop terminal button box and a disassembly method thereof in order to solve the problem that the locking screws of a conventional terminal button box are easy to fall off, resulting in production and maintenance difficulties.

[0005] The technical solution of the present invention is:

[0006] A detachable anti-drop terminal box comprises a box body, a front side of the box body is provided with a plurality of waist-shaped holes, a bottom side is provided with a plurality of wiring terminal holes whose number is the same as the waist-shaped holes, and the wiring terminal holes are connected with the corresponding waist-shaped holes, and the wiring terminals are inserted into the wiring terminal holes and fixed by locking screws;

[0007] The waist-shaped hole includes two screw holes, a retaining groove and an elastic baffle. The retaining groove is located between the two screw holes. The elastic baffle is installed in the aforementioned retaining groove. The bottom surface of the elastic baffle is connected to the waist-shaped hole and is formed as one piece. A retaining block is respectively provided at both ends of the top surface of the elastic baffle. When the elastic baffle is in a stable state, the two retaining blocks are located above the corresponding locking screws.

[0008] Furthermore, a gap is provided between the elastic baffle and the baffle groove.

[0009] Furthermore, the distance between the elastic baffle and the edge of the adjacent screw hole is 2-3 mm.

[0010] Furthermore, the number of the waist-shaped holes is 8 or 16.

[0011] Furthermore, when the elastic baffle is in a natural state, the baffle is located 1-8 mm above the corresponding locking screw.

[0012] A method for disassembling a detachable anti-drop terminal button box comprises the following steps:

[0013] The locking screw is loosened from the wiring terminal, and a vertical force is applied to the elastic baffle. The elastic baffle is deformed so that the stopper in the force application direction avoids the top of the locking screw on the corresponding side, and the locking screw can slide out of the screw hole.

[0014] Beneficial effects of the present invention:

[0015] The box body and the plurality of locking screws of the present invention can prevent the locking screws from falling off and can also be normally disassembled through the limitation of the stopper and the deformation of the elastic baffle.

[0016] When the elastic baffle of the present invention is installed, it deforms but does not break due to the gap between it and the baffle groove, which reduces the cost of rework during the production process and the maintenance cost after the product is put into operation, realizes the assemblability and maintainability of the product, and reduces the comprehensive cost of the instrument.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0023] A detachable anti-drop terminal box comprises a box body 1, wherein the front of the box body 1 is provided with a plurality of waist-shaped holes, and the bottom is provided with a plurality of terminal holes whose number is the same as that of the waist-shaped holes, and the terminal holes are connected with the corresponding waist-shaped holes, and the terminal 3 is inserted into the terminal hole and fixed by a locking screw 2; the waist-shaped hole comprises two screw holes 4, a retaining groove 7 and an elastic baffle 5, wherein the retaining groove 7 is located between the two screw holes 4, and the elastic baffle 5 is installed in the retaining groove 7, and the bottom surface of the elastic baffle 5 is connected with the waist-shaped hole and is integrally formed, and a stop block 6 is respectively provided at both ends of the top surface of the elastic baffle 5, and when the elastic baffle 5 is in a stable state, the two stop blocks 6 are located above the corresponding locking screws 2.

[0024] In this embodiment, an elastic baffle 5 integrally formed with the box body is provided to prevent the screw from falling off; the wiring terminal 3 is inserted into the wiring terminal hole. After it is in place, the locking screw 2 is placed above the screw hole 4, and the screwdriver applies a vertical force to the locking screw 2, so that the elastic baffle 5 is deformed and the locking screw 2 slides into the screw hole 4. After the elastic baffle 5 rebounds, it is located above the locking screw 2, which prevents the locking screw 2 from falling off when it is not locked. The screw is tightened using a screwdriver, and the installation is completed.

[0025] Furthermore, a gap 8 is provided between the elastic baffle 5 and the retaining groove 7; the distance between the elastic baffle 5 and the edge of the adjacent screw hole 4 is 2-3 mm; when the elastic baffle 5 is in a natural state, the stopper 6 is located 1-8 mm above the corresponding locking screw 2.

[0026] In this embodiment, the elastic baffle plate deforms without breaking due to the gap between it and the baffle groove, effectively reducing the cost of rework during the production process and maintenance costs after the product is put into operation, achieving the assemblability and maintainability of the product, and reducing the overall cost of the instrument.

[0027] A method for disassembling a detachable anti-drop terminal button box comprises the following steps:

[0028] The locking screw 2 and the terminal 3 are loosened, and a vertical force is applied to the elastic baffle 5. The elastic baffle 5 is deformed so that the stopper 6 in the force application direction avoids the top of the locking screw 2 on the corresponding side, and the locking screw 2 can slide out of the screw hole 4.

[0029] The terminal button box of the present invention can prevent the locking screw from falling off and can normally remove the locking screw. The structure is simple and the assembly process is simple, which reduces the cost of rework during the production process and the maintenance cost after the product is put into operation, realizes the assemblability and maintainability of the product, and reduces the comprehensive cost of the instrument.

[0030] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
