Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric energy meter plug-in technology, and in particular to an electric energy meter plug-in piece with a guiding function. BACKGROUND

[0002] An electric energy meter, also known as an electric energy meter or a watt-hour meter, is an important component in an electric power system and is used to measure and record the use of electric energy. Common types include mechanical electric energy meters, electronic electric energy meters, and smart electric energy meters. The current electric energy meter is assembled in a meter box as shown in the accompanying drawings, and is connected to an electrical accessory such as a circuit breaker through a plug-in interface at the bottom and a wire to control conduction. In the traditional wire connection, the wire ends are inserted into the plug-in holes of the electric energy meter and the circuit breaker, respectively, and the wire ends are pressed tightly using fastening bolts provided on the side walls of the plug-in holes to achieve circuit conduction. However, in actual use, there is often a problem of loose wire crimping, which can cause poor line conduction and further lead to power problems such as disconnection and short circuit. Moreover, the operation efficiency is slow when connecting the wire, which affects the work efficiency during continuous electrical assembly. Figure 1 To address the problems with wire connection, a plug-in piece has been developed to replace the wire connection. The plug-in piece has multiple plug-in tips that match the plug-in holes of the electric energy meter, and each plug-in tip is composed of a pair of plug-in petals. The plug-in petals are usually hollow structures and are inclined outward, as shown in

[0003] When the plug-in piece is fixed and assembled in the meter box, the electric energy meter is assembled from top to bottom, as shown in Figure 3 The plug-in tips are inserted into the plug-in holes of the electric energy meter. At the same time, the plug-in holes cause the plug-in petals to deflect inward, and the reaction force of the plug-in petals is tightly attached to the inner wall of the plug-in hole. This achieves stable plug-in conduction without the need for bolt fastening, and effectively improves the assembly efficiency of the electric energy meter. Figure 2 However, after a period of use, the electric energy meter is usually checked and disassembled for repair in case of circuit failure. The plug-in operation is also included when the electric energy meter is assembled. This results in multiple plug-in operations between the electric energy meter and the plug-in tips. Before plug-in, the electric energy meter is not fixed to the meter box, so when plug-in is suspended, if the plug-in hole and the plug-in tip are misaligned, as shown in

[0004] under the action of external force, the plug-in petals cannot be smoothly inserted into the plug-in hole, as shown in Figure 4 The single plug-in petal is located outside the plug-in hole, which causes the plug-in petal to break and damage, and the entire plug-in piece with multiple plug-in tips needs to be replaced, resulting in increased costs. Figure 4 INVENTION CONTENTS

[0005] ​Aiming at the above problems, the application aims to provide an electric energy meter connector with a guiding function, which can realize the guiding function of the electric energy meter connector operation, avoid damage to the connector end, and reduce replacement cost.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the application is as follows: an electric energy meter connector with a guiding function, the electric energy meter has a connector hole, a connector with a plurality of connector ends inserted into the connector hole is arranged in the meter box assembled with the electric energy meter, each connector end is composed of a connector half, characterized in that: a guiding member is arranged on each connector half connector end to connect the connector halves, and the guiding member moves axially along the connector end under the driving of the connector hole of the electric energy meter.

[0007] Preferably, the guiding member is a guiding ring that is sleeved on the connector end and connects the connector halves, and the inner diameter of the guiding ring is greater than the outer diameter of the connector end after being inserted into the connector hole.

[0008] Preferably, a support column is arranged in each of the connector halves and abuts against each side of the connector half.

[0009] Preferably, a support spring is arranged in each of the connector halves and abuts against each side of the connector half.

[0010] The beneficial effects of the application are: the connector connects the split connector halves through the guiding member, and in the electric energy meter connector process, the guiding member limits the further splitting of the connector halves by the connector hole under the deflection effect, and the split connector halves can be inserted into the connector hole as a whole, thereby realizing the guiding function of the connector operation, avoiding damage to the connector end, and reducing replacement cost.

[0021] In order to make the ordinary skilled in the art better understand the technical scheme of the present application, the technical scheme of the present application is further described below in combination with the drawings and examples.

[0022] Referring to the drawings Figures 1-9 As shown in the figure, the pressing bolt is used to press the plug-in petals, the electric energy meter 1 has a plug-in hole 1a, and the plug-in member composed of a plurality of plug-in end heads 2 inserted into the plug-in hole 1a is arranged in the meter box in which the electric energy meter 1 is assembled. Each of the plug-in end heads 2 is composed of a plug-in petal 21 split in half. When the electric energy meter is assembled, the plug-in member is first fixedly installed in the meter box, and then the electric energy meter is moved downward from the top of the plug-in member, and the plug-in hole 1a is corresponded to the plug-in end head 2, that is, the plug-in end head 2 is quickly inserted into the plug-in hole 1a of the electric energy meter, and the quick plug-in of the electric energy meter is completed.

[0023] In order to solve the problem that the plug-in end head is damaged due to the deflection of the electric energy meter compared with the plug-in end head 2 during the plug-in assembly of the electric energy meter, as shown in the figure, a guide member is arranged on each plug-in end head 2 composed of the plug-in petals 21 split in half, and the guide member moves axially along the plug-in end head 2 under the driving of the plug-in hole 1a of the electric energy meter 1. Figure 5

[0024] ​Specifically, as shown in Figure 5 the guiding member is a guiding ring 3 sleeved on the insertion end 2 and connecting the two halves of the insertion petals 21, the inner diameter of the guiding ring 3 is larger than the outer diameter of the insertion end 2 after being inserted into the insertion hole la. Before the insertion operation, the guiding ring 3 is first sleeved on the two halves of the insertion petals 21 to connect the two halves of the insertion petals 21, so that the two halves of the insertion petals 21 can enter the insertion hole la together when the electric energy meter is moved downward for insertion, thereby realizing the guiding effect during the insertion into the insertion hole la. When the electric energy meter is continuously moved downward, the outer port of the insertion hole la drives the guiding ring 3 to move downward synchronously, the two halves of the insertion petals 21 shrink in the guiding ring 3, and the guiding ring continuously falls to the bottom of the insertion end 2 (as shown in the right side view), and the inner diameter of the guiding ring 3 is larger than the outer diameter of the insertion end 2 after being inserted into the insertion hole la, that is, after the insertion petals 21 shrink inwardly depending on the inside of the insertion hole la, the outer wall of the insertion petals 21 is still not in contact with the inner wall of the guiding ring 3, that is, the shrinkage of the guiding ring 3 does not affect the insertion petals 21, and the insertion petals 21 are in contact with the inner wall of the insertion hole la under the reaction force of the insertion petals 21, thereby ensuring the stability of the conduction after insertion. Figure 5

[0025] In order to avoid the falling of the guiding ring 3 during the above-mentioned insertion operation, the inner wall of the guiding ring 3 is preferably provided with an arc-shaped structure (not shown in the figure) in contact with the top of the insertion petals 21 (the top of the insertion petals 21 is usually provided with a circular structure to facilitate the insertion into the insertion hole la), thereby realizing the stability of the guiding ring 3 placed on the insertion petals 21 through the surface contact.

[0026] Since the electric energy meter has a high selling price and a long service period, in order to enable the traditional electric energy meter (which is provided with a bolt for pressing the wire on the side wall of the insertion hole) to continue to be used and to be quickly inserted with the insertion piece, as shown in Figure 8 a supporting column 4 is arranged in the two halves of the insertion petals 21 and abuts against each side of the insertion petals 21. The function is that since the traditional electric energy meter connected with the wire is provided with a pressing bolt 11 on the side wall of the insertion hole la, even after the traditional electric energy meter is inserted with the insertion piece, the operator will still perform a certain pressing operation according to the pressing bolt on the side wall of the insertion hole la, as shown in Figure 7 on the basis of the different rotating pressing forces of the operator, the hollow structure of the insertion petals 21 is easily deformed in the concave shape by the pressing bolt, and over a long period of time, the concave deformation of the insertion petals 21 is further increased, thereby causing the insertion petals 21 to be unable to contact the inner wall of the insertion hole la, thereby causing the circuit to be broken and other electricity problems, and therefore, the supporting column 4 is arranged in the two halves of the insertion petals 21, so that when the operator rotates and presses the pressing bolt, the inside of the insertion petals 21 is supported by the supporting column 4, thereby overcoming the problem of the concave deformation of the insertion petals 21, so that the insertion petals 21 can still abut against the inner wall of the insertion hole la or the pressing bolt, thereby ensuring the stability of the line conduction. ​

[0027] On the basis of the above, as shown in Figure 9 The application can also be provided with a support spring 5 in the half plug-in petals 21, which is connected to both sides of the plug-in petals 21, and can be equivalent to the role of the support column 4. When the compression bolt is compressed to operate the plug-in petals 21, the support spring 5 can overcome the compression force (the support spring 5 is axially corresponding to the compression bolt), so as to avoid the inner concave deformation of the plug-in petals 21, and the plug-in petals 21 can be further compressed on the inner wall of the plug-in hole 1a by the support spring 5, so as to improve the stability of the circuit conduction.

[0028] The principle of the application is that when the electric energy meter and the plug-in assembly are operated, the guide ring 3 is first sleeved on the half plug-in petals 21, the split plug-in petals 21 are connected, then the electric energy meter is moved down, the outer port of the plug-in hole 1a drives the guide ring 3 to move down synchronously, the half plug-in petals 21 are contracted in the guide ring 3, and the guide ring falls to the bottom of the plug-in end 2, so that the guide ring 3 realizes the guiding effect of the electric energy meter plug-in operation, and guarantees the stability of the conduction after the plug-in. The support column 4 or the support spring 5 provided in the plug-in part is used to overcome the extrusion deformation of the plug-in petals 21 caused by the compression bolt, so as to realize the effective protection of the plug-in part.

[0029] The basic principle, main features and advantages of the application are shown and described above. Various changes and improvements can be made to the application without departing from the spirit and scope of the application, and these changes and improvements all fall within the scope of the claimed application.
