Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to an electricity meter wiring terminal and an electricity meter. Background Technology

[0002] The terminal block of an electricity meter is a key component that connects the electricity meter to the external circuit. Its core structure is based on an insulating base with embedded copper conductive parts. The surface is often treated with nickel or tin plating to enhance its oxidation resistance. It is equipped with screws, pressure plates or spring clips and other fixing devices to hold and fix the wires.

[0003] In the existing technology, the transition at the terminal interface of the electricity meter is not smooth enough. During the installation of the electricity meter terminal and the connecting wire, if the connecting wire is pulled and bent, the bent connecting wire will press on the interface and produce a right angle bend. The core wire and insulation layer inside the connecting wire will bear concentrated stress at the bend, which will cause damage to the internal structure of the connecting wire. Moreover, the pulling force will be directly applied to the connection between the connecting wire and the terminal, which can easily cause the connecting wire to loosen and fall off. Utility Model Content

[0004] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide an electricity meter terminal block and an electricity meter, thereby solving the problem mentioned in the background art that the transition at the electricity meter terminal interface is not smooth enough, and if the connecting wire is pulled and bent at a right angle, it is easy to cause damage to the internal structure of the connecting wire, and the pulling force can easily cause the connecting wire to loosen and fall off.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A power meter terminal block, comprising:

[0007] An electricity meter, the electricity meter being provided with terminal connection wires and wiring terminals, further includes:

[0008] A clamping structure, arranged on the electricity meter, is used to clamp the terminal connection wires to improve their stability;

[0009] A guide structure, arranged on the clamping structure, is used to guide the bending angle of the terminal connection wire;

[0010] A sealing structure, arranged on the clamping structure, is used to improve the sealing performance at the connection between the terminal block and the terminal wire.

[0011] Preferably, the clamping structure includes:

[0012] The bearing seat is located on one side of the electricity meter;

[0013] A two-way lead screw is rotatably mounted inside a bearing seat;

[0014] Both threaded sleeves are threaded onto the double-acting lead screw;

[0015] Two clamping plates are respectively arranged on one side of the two threaded sleeves;

[0016] Several arc-shaped clamping slots are symmetrically opened inside the two clamping plates, and the terminal connecting wires pass through the corresponding arc-shaped clamping slots;

[0017] The guide assembly is arranged on the clamp.

[0018] Preferably, the guide component includes:

[0019] T-slots are formed inside the clamping plate;

[0020] The T-shaped bar is arranged on one side of the electricity meter and slidably installed inside the clamp.

[0021] Preferably, the clamping structure further includes a reinforcing component arranged in an arc-shaped clamping groove to increase clamping friction and reinforce the terminal connection wire.

[0022] Preferably, the reinforcement component includes:

[0023] Several rubber pads are arranged inside the corresponding arc-shaped clamping grooves;

[0024] Several rubber blocks are evenly arranged on the rubber pad and are in contact with the surface of the terminal connection wire.

[0025] Preferably, the guiding structure includes:

[0026] Several arc-shaped plates are evenly arranged on one side of the two clamping plates and correspond to the terminal connection lines;

[0027] An arc-shaped sleeve is placed at one end of an arc-shaped plate, and the terminal connection wire passes through the corresponding arc-shaped plate and arc-shaped sleeve.

[0028] Preferably, the sealing structure includes:

[0029] Several forming grooves are evenly distributed inside the two clamping plates;

[0030] The rubber sleeve is glued into the two corresponding molding grooves, and the rubber sleeve is glued to the connection line between the energy meter and the terminal.

[0031] Several connecting pipes are arranged on the corresponding clamps;

[0032] Several connecting holes are formed in the corresponding clamping plates and connected to the forming groove. The connecting holes are connected to the connecting pipe.

[0033] Preferably, the sealing structure further includes:

[0034] The protrusions are arranged inside the forming groove;

[0035] The groove is formed inside the rubber sleeve and is adapted to the protrusion.

[0036] This utility model also provides an electricity meter, including the aforementioned electricity meter wiring terminals.

[0037] The beneficial effects of this utility model are as follows:

[0038] This invention allows for the connection of a terminal wire to a terminal block. A rotatable bidirectional screw controls two clamping plates to hold the terminal wire in place. Rubber pads and blocks increase friction with the terminal wire, enhancing stability. Once clamped, the force of pulling on the terminal wire is prevented from directly acting on the connection between the terminal wire and the terminal block, thus preventing the terminal wire from loosening. Furthermore, when the terminal wire is pulled and bent, it bends along the arc of the arc-shaped sleeve, limiting the bending angle and distributing the bending stress evenly within the arc-shaped area, rather than concentrating it at a single point. This reduces the risk of damage to the internal structure of the cable and prevents right-angle bends.

[0039] In this invention, after the two clamping plates are combined to hold the terminal connecting wire, the upper and lower forming grooves are connected. Then, molten hot melt adhesive can be poured from the connecting tube into the forming groove. After the hot melt adhesive solidifies, it will be sleeved and bonded to the terminal connecting wire and the surface of the electricity meter to form a rubber sleeve. By using the adhesive setting of the rubber sleeve, the connection between the terminal connecting wire and the terminal can be sealed, which improves the connection stability of the terminal connecting wire and increases the dustproof and waterproof effect of the connection.

[0049] 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.

[0050] Example 1:

[0051] like Figures 1 to 6 As shown, this utility model provides a power meter terminal block, including: a power meter 1, a terminal connecting wire 101 and a terminal block 102 provided on the power meter 1, and a clamping structure arranged on the power meter 1 to clamp the terminal connecting wire 101 to improve its stability.

[0052] The clamping structure includes a bearing 2 arranged on one side of the electricity meter 1, a bidirectional lead screw 201 rotatably installed inside the bearing 2, two threaded sleeves 202 threadedly sleeved on the bidirectional lead screw 201, two clamping plates 203 respectively arranged on one side of the two threaded sleeves 202, several arc-shaped clamping grooves 204 symmetrically opened inside the two clamping plates 203, the terminal connecting wire 101 passing through the corresponding arc-shaped clamping grooves 204, and a guide assembly arranged on the clamping plate 203. The bidirectional lead screw 201 can be rotated to drive the two threaded sleeves 202 to move closer to each other, so that the two threaded sleeves 202 can drive the two clamping plates 203 to move closer and clamp the terminal connecting wire 101.

[0053] Specifically, the guiding components include a T-slot 205 formed inside the clamping plate 203 and a T-strip 206 arranged on one side of the electricity meter 1 and slidably installed inside the clamping plate 203. When the clamping plate 203 moves, it can slide on the T-strip 206 through the T-slot 205. The movement direction of the clamping plate 203 can be restricted by the T-slot 205 and the T-strip 206, while preventing the clamping plate 203 from deviating.

[0054] The clamping structure also includes a reinforcing component arranged in the arc-shaped clamping groove 204 to increase the clamping friction and reinforce the terminal connection line 101.

[0055] Specifically, the reinforcement components include several rubber pads 207 arranged inside the corresponding arc-shaped clamping grooves 204, and several rubber blocks 208 evenly arranged on the rubber pads 207 and in contact with the surface of the terminal connecting wire 101. The two adjacent clamping plates 203 can drive the rubber blocks 208 on the rubber pads 207 to press against the surface of the terminal connecting wire 101. The arrangement of multiple rubber blocks 208 can increase the contact friction with the terminal connecting wire 101 and improve the clamping stability of the terminal connecting wire 101.

[0056] Example 2:

[0057] Based on Embodiment 1, in order to guide the bending angle of the terminal connecting line 101 and avoid it from being bent at a right angle, a guide structure is arranged on the clamping structure.

[0058] The guiding structure includes several arc-shaped plates 3 evenly arranged on one side of the two clamping plates 203 and corresponding to the terminal connecting line 101, and an arc-shaped sleeve 301 arranged at one end of the arc-shaped plate 3. The terminal connecting line 101 passes through the corresponding arc-shaped plate 3 and arc-shaped sleeve 301. The end of the arc-shaped sleeve 301 has a trumpet-shaped arc design, which can guide the terminal connecting line 101 to bend along the arc of the arc-shaped sleeve 301 when bending, so as to avoid the terminal connecting line 101 forming a right angle bend.

[0059] Example 3:

[0060] Based on Embodiment 1, in order to improve the sealing performance at the connection between the terminal block 102 and the terminal connecting line 101, a sealing structure is arranged on the clamping structure.

[0061] The sealing structure includes several molding grooves 4 evenly distributed inside the two clamping plates 203, adhesive sleeves 401 bonded to the corresponding two molding grooves 4, adhesive sleeves 401 bonded to the electricity meter 1 and the terminal connection line 101, several connecting pipes 402 arranged on the corresponding clamping plates 203, and several connecting holes 403 opened in the corresponding clamping plates 203 and connected to the molding grooves 4, the connecting holes 403 being connected to the connecting pipes 402. When the two clamping plates 203 are combined, the two molding grooves 4 are in a connected state. Then, molten hot melt adhesive is poured into the molding grooves 4, so that the hot melt adhesive forms adhesive sleeves 401 and is fitted and bonded to the terminal connection line 101 and to one side of the electricity meter 1, thereby increasing the sealing and waterproof effect at the connection between the terminal 102 and the terminal connection line 101.

[0062] The sealing structure also includes a protrusion 404 arranged inside the molding groove 4 and a groove 405 opened inside the rubber sleeve 401 and adapted to the protrusion 404. By setting the protrusion 404 in the molding groove 4, the solidified rubber sleeve 401 will form the groove 405, so that the end of the rubber sleeve 401 is divided into two halves. When the adhesiveness of the rubber sleeve 401 fails, the upper and lower clamps 203 can be separated, and then the rubber sleeve 401 can be snapped from the groove 405, which helps to detach the rubber sleeve 401 from the terminal connection line 101 and rearrange it.

[0063] This utility model also provides an electricity meter, including electricity meter wiring terminals.

[0064] Working principle: After inserting the terminal connecting wire 101 into the wiring terminal 102 of the energy meter 1, the bidirectional lead screw 201 can be rotated. The two ends of the bidirectional lead screw 201 have threads facing opposite directions, and these threads are adapted to the two threaded sleeves 202. This allows the rotating bidirectional lead screw 201 to drive the two threaded sleeves 202 closer together, which in turn drives the two clamping plates 203 closer together. The approaching clamping plates 203 cause the rubber blocks 208 on the rubber pads 207 to press against the surface of the terminal connecting wire 101, ultimately causing the two clamping plates 203 to completely merge. During this process, the corresponding two arc-shaped plates 3 merge with the arc-shaped sleeves 301. The ends of the arc-shaped sleeves 301 have a flared arc design, which guides the terminal connecting wire 101 to bend along the arc of the arc-shaped sleeves 301, preventing the terminal connecting wire 101 from forming a right-angle bend. Simultaneously, the merging of the two clamping plates 203 ensures that the forming grooves 4 on the two clamping plates 203 are in a connected state. (See reference...) Figure 5 Then, molten hot melt adhesive is poured into the connecting pipe 402, allowing it to flow into the molding tank 4 through the connecting hole 403. The hot melt adhesive, influenced by the molding tank 4 and the terminal connecting wire 101, solidifies to form a sleeve 401. Figure 2As shown, the rubber sleeve 401 will be fitted and bonded to the terminal connection wire 101 and to one side of the energy meter 1 to increase the sealing and waterproof effect at the connection between the wiring terminal 102 and the terminal connection wire 101.
