Description

Technical Field

[0001] This utility model relates to the technical field of electricity meter accessories, and in particular to a battery box assembly for electricity meters. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy. It is also called an electricity meter, kilowatt-hour meter, or kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. The battery box is a key backup power module on the electricity meter. It can automatically switch power supply when the main power supply fails, so that the electricity meter can continue to work in extreme environments, thereby ensuring the integrity and reliability of electricity metering data.

[0003] Application No. 202420857152.2 discloses a battery box assembly and an energy meter for an energy meter with terminals that are less prone to deformation and provide more stable contact. The technical solution adopted includes: a battery box body and a connector. The battery box body includes a box body, a box cover disposed on the top of the box body, a negative conductive sheet disposed in the box body, and a positive conductive sheet disposed in the box cover. A negative contact fixing seat is integrally formed at the upper end of the box body, and a positive contact fixing seat is integrally formed at the bottom of the box cover and disposed parallel to the negative contact fixing seat. The negative conductive sheet has a first negative contact that fits against the bottom of the negative contact fixing seat, and the positive conductive sheet has a first positive contact that fits against the bottom of the positive contact fixing seat.

[0004] The above solution has shortcomings in use. When the rotating cover is connected to the box body, the positive conductive plate will rotate synchronously with the cover and generate relative sliding friction with the positive cap of the battery. This repetitive friction movement will cause wear on the contact surface, which may lead to problems such as poor battery contact and unstable power supply. To address this, we provide a battery box assembly for electricity meters. Utility Model Content

[0005] This utility model provides a battery box assembly for an electricity meter, which can avoid sliding friction between the positive conductive plate and the positive cap of the battery during battery installation, thereby preventing wear on the contact surface and further ensuring the stability of battery power supply.

[0006] The purpose and effect of this utility model for a battery box assembly for an electricity meter are achieved by the following specific technical means: A battery box assembly for an electricity meter includes a box body, a cover disposed on the top of the box body, a battery body disposed inside the box body, a negative electrode conductive sheet disposed on the bottom of the box body, and a positive electrode conductive sheet disposed on the bottom surface of the cover body, and further includes:

[0007] The connecting component, which is set on the cover to prevent sliding friction between the positive electrode conductive sheet and the battery body, includes a set of slots opened in the inner wall of the box, a set of through slots opened in the upper surface of the cover, an L-shaped plate set inside each slot, and a thrust structure set inside the set of through slots.

[0008] A positioning component, mounted on the cover, is used to ensure that the cover drives the positive conductive sheet to descend vertically.

[0009] Preferably, the thrust structure includes a set of support rods slidably connected to each L-shaped plate, with both the left and right ends of each support rod connected to the inner wall of the slot, and each support rod having a spring sleeved on its exterior.

[0010] Preferably, a pinch block is fixedly connected to the top of each L-shaped plate, and a rubber sleeve is fitted over the outside of each pinch block.

[0011] Preferably, each of the through grooves has a sliding groove on its inner wall, and a sealing plate is slidably connected to the inner wall of each sliding groove. The other end of each sealing plate is connected to one side of an L-shaped plate.

[0012] Preferably, a protective pad is fixedly connected to the bottom surface of each L-shaped plate.

[0013] Preferably, the positioning component includes a set of positioning holes formed on the bottom surface of the cover, and a positioning rod is inserted into the interior of each positioning hole, with the bottom end of each positioning rod connected to the upper surface of the box.

[0014] Preferably, the bottom of each positioning hole is flared, and the top of each positioning rod is flared.

[0015] Preferably, a pressure block is fixedly connected to the bottom surface of the cover, and the pressure block is located above the positive electrode conductive sheet.

[0016] Preferably, the exterior of the housing is provided with a connector, which consists of a set of soldered pins and a set of resilient contacts.

[0017] Preferably, a group of the elastic contacts are in contact with the negative conductive sheet and the positive conductive sheet respectively.

[0018] Beneficial effects:

[0019] 1. The cover can be connected to the top of the box through the set connection components, thereby forming a stable positive conductive sheet. The positive conductive sheet will directly contact the positive cap of the battery body, avoiding friction when they come into contact, thus preventing wear on the contact surface and further ensuring the stability of the power supply of the battery body.

[0020] 2. The positioning components effectively limit the circumferential rotation of the cover, ensuring that the cover is pressed down smoothly in the vertical direction. This keeps the positive conductive sheet on a vertical trajectory, avoiding abnormal friction between the positive conductive sheet and the positive cap of the battery body caused by the deflection of the cover. This protects the integrity of the coating on the surface of the positive conductive sheet, improves contact reliability, and extends the service life of the battery box assembly.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] First Embodiment

[0031] As attached Figure 1 To be continued Figure 4As shown: A battery box assembly for an electricity meter includes a box body 1, a cover 2 disposed on the top of the box body 1, a battery body 3 disposed inside the box body 1, a negative electrode conductive plate 4 disposed at the bottom of the box body 1, and a positive electrode conductive plate 5 disposed on the bottom surface of the cover 2. When the battery body 3 is inside the box body 1, the negative electrode of the battery body 3 will be disconnected from the negative electrode conductive plate 4 at the bottom. When the cover 2 is stably placed on the top of the box body 1, the positive electrode cap of the battery body 3 will contact the positive electrode conductive plate 5.

[0032] A pressure block 8 is fixedly connected to the bottom surface of the cover 2. The pressure block 8 is located above the positive conductive sheet 5. After the cover 2 is installed, the pressure block 8 will be above the positive conductive sheet 5 and there will be a certain gap between it and the positive conductive sheet 5. This can limit the movement of the positive conductive sheet 5 and prevent it from being squeezed and deformed excessively. A connector 9 is provided on the outside of the box 1. The connector 9 consists of a set of solder pins and a set of elastic contacts. The set of elastic contacts contacts the negative conductive sheet 4 and the positive conductive sheet 5 respectively. The set of elastic contacts is the negative contact part and the positive contact part respectively. The top of the negative contact part forms a permanent elastic contact with the negative conductive sheet 4. After the positive conductive sheet 5 is stabilized, it will form an elastic contact with the positive contact part.

[0033] Second Embodiment

[0034] As attached Figure 2 Appendix Figure 3 Appendix Figure 4 With appendix Figure 5 As shown: The connecting component 6, disposed on the cover 2, is used to prevent sliding friction between the positive conductive sheet 5 and the battery body 3. It includes a set of slots 601 formed in the inner wall of the box 1, a set of through grooves 602 formed in the upper surface of the cover 2, an L-shaped plate 603 disposed inside each slot 601, and a thrust structure disposed inside the set of through grooves 602. The thrust structure includes a set of support rods 604 slidably connected to each L-shaped plate 603. The left and right ends of each support rod 604 are connected to the inner wall of the slot 601. A spring 605 is sleeved on the outside of each support rod 604. The extension and contraction of the spring 605 can push the L-shaped plate 603 into the slot 601, thereby stabilizing the cover 2 on the top of the box 1. The positive conductive sheet 5 will directly contact the positive cap of the battery body 3, which can prevent sliding friction between them, thereby preventing wear on the contact surface and further ensuring the stability of the power supply of the battery body 3.

[0035] Each L-shaped plate 603 has a pinch block 606 fixedly connected to its top, and each pinch block 606 is covered with a rubber sleeve. The pinch block 606 facilitates the operator to pull the L-shaped plates 603 together. Each through groove 602 has a sliding groove 607 on its inner wall, and a sealing plate 608 is slidably connected to the inner wall of each sliding groove 607. The other end of each sealing plate 608 is connected to one side of the L-shaped plate 603. When the cover 2 is stable on the box 1, the L-shaped plate 603 will also pull the sealing plate 608 to slide out of the sliding groove 607, which can form a seal on the through groove 602, thereby effectively reducing the entry of external dust. Each L-shaped plate 603 has a protective pad 609 fixedly connected to its bottom surface. The protective pad 609 can prevent the L-shaped plate 603 from colliding with the battery body 3.

[0036] Third Embodiment

[0037] As attached Figure 2 Appendix Figure 4 With appendix Figure 6 As shown: Positioning component 7, disposed on cover 2, is used to ensure that cover 2 drives the positive conductive sheet 5 to descend vertically. Positioning component 7 includes a set of positioning holes 701 opened on the bottom surface of cover 2. Each positioning hole 701 is inserted with a positioning rod 702. The bottom end of each positioning rod 702 is connected to the upper surface of box 1. When the positioning rod 702 is inside the positioning hole 701, it can effectively restrict the circumferential rotation of cover 2, ensuring that cover 2 is pressed down smoothly in the vertical direction, thereby keeping the positive conductive sheet 5 in a vertical movement trajectory. This avoids abnormal friction between the positive conductive sheet 5 and the positive cap of battery body 3 caused by the deflection of cover 2, which not only protects the integrity of the coating on the surface of positive conductive sheet 5, but also improves contact reliability and can extend the service life of battery box assembly. The bottom of each positioning hole 701 is flared, and the top of each positioning rod 702 is flared. During the pressing down of cover 2, the conical structure can also achieve automatic centering through the inclined guide, ensuring that the positioning rod 702 is smoothly inserted into the positioning hole 701.

[0038] Working principle: First, place the battery body 3 inside the box 1. Then, pinch the two pinch blocks 606, and the two L-shaped plates 603 will move closer to each other and compress the spring 605. Next, place the cover 2 on top of the box 1 and let the positioning rod 702 pass through the positioning hole 701. The cover 2 will then move the L-shaped plates 603 into the box 1 simultaneously. As the cover 2 moves down, the L-shaped plates 603 will move to the slot 601. The spring 605 will then extend and push the L-shaped plates 603, making them lock into the slot 601. The cover 2 will then be stable on top of the box 1, allowing the positive conductive plate 5 at the bottom of the cover 2 to directly contact the positive cap of the battery body 3, avoiding friction between them and preventing wear on the contact surface, thus further ensuring the stability of the power supply from the battery body 3.
