Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a meter connector with a positioning structure. Background Technology

[0002] In power systems, electricity meters are crucial devices for measuring user electricity consumption, and their installation stability and accuracy are paramount. Traditional meter connectors often lack effective positioning mechanisms during installation, leading to problems such as loosening and misalignment after installation, which in turn affects the meter's measurement accuracy and lifespan. Furthermore, with the continuous upgrading and intelligent development of power systems, higher demands are placed on the positioning accuracy and ease of installation of meter connectors. However, existing meter connector technologies still have many shortcomings in terms of positioning mechanisms and ease of installation, failing to meet the needs of practical applications.

[0003] For example, in the Chinese invention patent with publication number CN105548636A, a hook structure 4 is shown in a connector device that is directly connected to an electricity meter. In the prior art, the positioning structure of the electricity meter often uses an integrated protrusion for positioning. Once this structure is damaged, it cannot be replaced, and the elastic deformation effect is poor, making disassembly and installation inconvenient. Utility Model Content

[0010] The elastic locking part includes a first arc-shaped abutment section and a second arc-shaped abutment section respectively disposed on its left and right sides. After the elastic locking part is connected to the power metering device, the first arc-shaped abutment section and the second arc-shaped abutment section provide horizontal outward pressure.

[0011] In this utility model, the mounting groove includes a main groove body and a first side groove and a second side groove disposed on both sides of the main groove body, wherein the first side groove and the second side groove are both connected to the main groove body;

[0012] The limiting feet are disposed at both ends of the elastic snap-fit ​​portion, and the two limiting feet are respectively inserted into the first side groove and the second side groove.

[0013] In this invention, a connecting piece for connecting the elastic snap-fit ​​portion is also included;

[0014] The elastic locking portion includes a first limiting side, a second limiting side, a third limiting side, and a fourth limiting side. The first arc-shaped abutting section is located between the first limiting side and the second limiting side, and the second arc-shaped abutting section is located between the third limiting side and the fourth limiting side.

[0015] In this invention, the limiting foot, the elastic locking part, and the connecting piece are an integral structure.

[0016] This invention also includes a conductive mechanism and a rotating mechanism. The meter connector achieves the connection and disconnection of the overall circuit through the rotating mechanism.

[0045] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] Example 1

[0047] like Figures 1-4The rotary connector assembly and meter connector shown are designed to address the shortcomings of traditional meter connector plug-in modules, which typically feature protruding shafts on both sides. A housing 222, which rotates to engage with these protrusions, enables power disconnection. This structure occupies significant space on both sides of the contact group, making it difficult to mount additional indicating components 213. Furthermore, with only two protruding shafts as rotational support points, the structure has low strength and cannot be replaced after breakage.

[0048] Specifically, the meter connector of this utility model includes a connector housing 1 and a connector assembly 2. The connector assembly 2 mainly consists of a rotating mechanism 22 and a conductive mechanism 21. The connector assembly 2 can achieve power-off and power-on operations by rotating the rotating mechanism 22. In particular, the conductive mechanism 21 includes four stationary contacts 211 (i.e., conductive bars) and conductive terminals 212. The rotating mechanism 22 consists of four connecting posts 221 that mate with the stationary contacts 211 and a housing 222 that accommodates the connecting posts 221. That is, the stationary contacts 211 and the connecting posts 221 correspond one-to-one, with one connecting post 221 mates with one stationary contact 211. The connecting posts 221 are used for inserting and connecting power measuring equipment, such as an energy meter, voltmeter, power factor meter, etc.

[0049] Furthermore, the housing 222 is also provided with positioning blocks 2222, and the connector housing 1 is provided with positioning grooves 11 that cooperate with the positioning blocks 2222, forming a snap-fit ​​relationship 34 between them. In this embodiment, there are two positioning blocks 2222, which are respectively located at both ends of the top of the housing 222, and the number and position of the positioning grooves 11 correspond to the positioning blocks 2222. When the rotating mechanism 22 is closed and in the conducting state, the positioning blocks 2222 are connected with the positioning grooves 11 to form a limiting structure. In particular, in order to increase the mechanical strength of the positioning blocks 2222, reinforcing ribs 2223 are also provided at the bottom of the positioning blocks 2222.

[0050] Each stationary contact 211 has an independently fitted conductive terminal 212 at its bottom for connecting external wires or connectors. The conductive terminal 212 is common knowledge known to those skilled in the art and will not be described in detail here. On the upper left and right sides of the stationary contact 211, there are limiting arms 2111 extending to the same side. The limiting arms 2111 and the stationary contact 211 are an integral structure. The two limiting arms 2111 are used to clamp the connecting post 221 to realize circuit conduction. If it is necessary to disconnect the power, the connecting post 221 can be separated from the clamping arm.

[0051] Reference Figures 5-6To save space and increase rotational strength while designing a replaceable rotating shaft 2233, the connector assembly 2 of this invention can also be detachably equipped with a rotating assembly 223 on the stationary contact piece 211, with one end of the connecting post 221 rotatably connected to the rotating assembly 223. That is, the connecting post 221 can rotate by using the end connected to the rotating assembly 223 as a fulcrum, thereby realizing the connection and separation between it and the limiting arm 2111, and thus realizing the circuit breaking or conduction.

[0052] Specifically, the rotating assembly 223 is located between the limiting arm 2111 and the conductive terminal 212. A rectangular insertion hole 2112 is provided in the middle of the stationary contact piece 211, and the rotating assembly 223 is vertically and interference-fitted into the insertion hole 2112. The rotating assembly 223 includes a rotating body 2231, an insert piece 2232, and a rotating shaft 2233 inserted into the rotating body 2231. A limiting seat 22311 is provided at the bottom of the rotating body 2231, and a hole for the rotating shaft 2233 is provided at the top of the rotating assembly 2233 to facilitate the insertion of the rotating shaft 2233 into the rotating body 2231. That is, in this embodiment, the rotating shaft 2233 is detachably inserted into the rotating body 2231. The upper part of the rotating body 2231 described in this embodiment is... Figure 5 The front part of the rotating body 2231 will be described in detail from the direction shown in the figure. It is not a reference to the actual position of the feature. Its position is related to the placement angle of the component and is not limited.

[0053] In this embodiment, the rotating shaft 2233 is mounted on the rotating body 2231 via a pin. This is to allow for timely replacement of the rotating shaft 2233 in case of breakage and to limit the insertion piece 2232, preventing it from moving outwards. However, to meet certain lightweight design requirements and improve economic efficiency, the rotating shaft 2233 can also be integrated with the rotating body 2231.

[0054] Reference Figures 7-8A top post 2214 is movably disposed within the connecting post 221. When the rotating assembly 223 is inserted into the stationary contact piece 211, the bottom of the top post 2214 abuts against the top of the front end of the rotating body 2231, and the top post 2214 and the side of the rotating body 2231 are perpendicular to each other. At this time, the connector is in a conductive state. As the rotating assembly 223 rotates, the bottom of the top post 2214 slides along the outer side of the rotating body 2231. In particular, a groove 22312 is provided at the front end of the rotating body 2231 and the insert piece 2232. An arc-shaped transition surface 22313 is provided between the groove 22312 and the side of the rotating body 2231 and the insert piece 2232, which can provide assistance for the rotation of the rotating assembly 223. The arc-shaped transition surface 22313 includes end point a and end point b. When the top post 2214 is located between end point a and the side of the rotating body 2231, the connector is in a conductive state. When the top post 2214 is located between end point a and end point b, the rotating component 223 is in a state of separation, at which time the angle between the rotating component 223 and the connector housing 1 is between 90° and 60°. When the top post 2214 is located within the groove 22312, the connector is in a disconnected state.

[0055] Specifically, the groove 22312 includes a limiting part 22315, which is the lowest point of the groove 22312. When the top post 2214 is located at the limiting part 22315 of the groove 22312, the connector is in a disconnected state. The groove 22312 has a V-shaped structure. The front end shape of the insert 2232 is similar to the front end shape of the rotating body 2231, and when the insert 2232 is inserted into the rotating body 2231, its end face is at the same horizontal plane as the end face of the rotating body 2231.

[0056] The bottom surface of the top post 2214 is provided with a spherical portion 22141. The bottom surface of the spherical portion 22141 abuts against the side surface of the insert 2232, and the range of motion of the top post 2214 is within the side surface of the insert 2232. That is, regardless of whether the rotating component 223 is in the on or off state, it abuts against the side surface of the insert 2232, i.e., the side surface of the insert 2232 is tangent to the spherical portion 22141. The insert 2232 is provided to prevent the top post 2214 from directly contacting the rotating body 2231, thereby preventing wear on its surface and causing errors in the movement of the top post 2214, which would affect the connection effect of the meter. In particular, in this embodiment, the insert 2232 is made of metal, such as copper, iron, aluminum, or a metal alloy. The hardness of the insert 2232 should be greater than or equal to the hardness of the top post 2214, thereby preventing direct wear on the side surface of the insert 2232 after contact.

[0057] Furthermore, the connecting column includes a connecting portion 2212 that cooperates with the rotating assembly 223, a connecting body 2213 that cooperates with the limiting arm 2111, and a plug portion 2211 for connecting with the meter. In this embodiment, the connecting portion 2212 is disposed below the connecting body 2213, and the plug portion 2211 is disposed above the connecting body 2213.

[0058] The connector 2211 consists of a four-lobed, outwardly opening head 22111. Specifically, let x be the distance between the center point of the pivot 2233 and the top of the side of the insert 2232, and y be the distance between the center point of the pivot 2233 and the lowest point of the groove 22312, i.e., the lowest point of the limiting part 22315. In this design, to achieve the following: when the connector is in the conductive state, the top post 2214 moves upward and opens the head 22111 outward; when the connector is in the disconnected state, the top post 2214 moves downward to reset the head 22111. That is, to facilitate easier removal or fixing of the meter, the length of y is less than the length of x. In this embodiment, the length of x is defined as 1.6y.

[0059] Example 2

[0060] Reference Figures 9-10 As shown, based on Embodiment 1, the rotating mechanism 22 further includes a short-circuit structure 224, which mainly consists of two conductive blocks 2241. The housing 222 of the rotating mechanism 22 is provided with a slot 2221 for mounting the conductive blocks 2241. The conductive blocks 2241 are mounted in the slot 2221. When the rotating mechanism 22 is in the conducting state, the conductive blocks 2241 and the limiting arm 2111 do not contact each other. When the rotating mechanism 22 moves to the disconnected state, the conductive blocks 2241 rotate together with the housing 222. After the rotating mechanism 22 is in the disconnected state, the conductive blocks 2241 abut against two adjacent stationary contacts 211, that is, short-circuit two adjacent stationary contacts 211.

[0061] Specifically, when the connector is in the conductive state, the conductive block 2241 is located behind the stationary contact piece 211, and a conductive block 2241 is disposed between the two sets of stationary contact pieces 211. In Embodiment 1, there are four stationary contact pieces 211, while in this embodiment there are two conductive blocks 2241. That is, the conductive block 2241 is used to short-circuit two adjacent stationary contact pieces 211, thereby realizing the short-circuit between two adjacent stationary contact pieces 211 and the uninterrupted power meter replacement.

[0062] To achieve the above solution, the spacing between two adjacent stationary contact pieces 211 should be less than the width of the conductive block 2241. In this embodiment, the conductive block 2241 has a U-shaped structure, and it is interference-fitted with the slot 2221. The conductive block 2241 includes a first conductive arm and a second conductive arm, and the first conductive arm and the second conductive arm abut against the stationary contact pieces 211 on the left and right sides, respectively.

[0063] In particular, once the conductive block 2241 is inserted into the slot 2221, it can be further reinforced with bolts.

[0064] Example 3

[0065] like Figure 11 As shown, based on Embodiment 1 or Embodiment 2, the connector 2 in this embodiment further includes an indicator component 213. That is, the technical solution in this embodiment can be implemented in conjunction with the technical solutions in Embodiment 1 or Embodiment 2. The indicator component 213 mainly includes a circuit board 2131, a micro switch, two light-emitting elements 2133, and multiple electronic components constituting the indicator circuit, such as resistors, capacitors, and reactors. In this embodiment, the light-emitting elements 2133 are two light-emitting diodes of different colors. However, any device capable of emitting different colors is acceptable, such as heterochromatic LEDs, matrix LEDs, and surface-mount LEDs.

[0066] Specifically, the micro switch is an indicator 2132, and the indicator component 213 is disposed inside the connector housing 1, with one end extending outward from the connector housing 1 and positioned on the movement path of the rotating mechanism 22. When the rotating mechanism 22 is in the ON position, it contacts the micro switch; when it is in the OFF position, it separates from the micro switch. One of the two light-emitting elements 2133 is used to indicate the state of the rotating mechanism 22 in conjunction with the micro switch, while the other is used to indicate whether the circuit is energized.

[0067] Example 4

[0068] Reference Figure 12 , Figure 13 , Figure 16 , Figure 17 Based on one or more combinations of Embodiment 1, Embodiment 2, or Embodiment 3, the connector further includes a dust cover 3. Specifically, the connector housing 1 also has a limiting groove 13 for storing and mounting the dust cover 3. The dust cover 3 includes four end caps 31 and connecting straps 32 connecting the four end caps 31. In this embodiment, the connecting straps 32 and the end caps 31 are an integral structure. The left and right ends of the dust cover 3 are also provided with protrusions 33 that cooperate with the limiting grooves 13, that is, protrusions 33 are provided on the outer side of the leftmost end cap 31 and the rightmost end cap 31.

[0069] The limiting groove 13 is a U-shaped groove with its opening facing forward, but it is not limited to a U-shaped groove. That is, as long as there is a limiting structure at one end of the groove to prevent the protrusion from sliding out from the other end, it is acceptable. For example, a stop 36 can be set at the other end of the opening to prevent the protrusion from sliding out.

[0070] The limiting groove 13 is located on the upper part of the connector housing 1. The dust cover 3 is fixed by snapping it into the limiting groove 13. That is, when the dust cover 3 is not needed, it can be snapped into the limiting groove 13 for storage or transportation to prevent loss.

[0071] The dust cover 3 has an L-shaped buckle 34 in the middle. Specifically, the buckle 34 is set on the connecting strip 32 in the middle of the dust cover 3. In order to facilitate installation and positioning, the housing 222 of the rotating mechanism 22 is also provided with a slot 2224 that cooperates with the buckle 34. When the dust cover 3 is installed on the head 22111 of the connecting column 221, the buckle 34 is engaged in the slot 2224 for auxiliary positioning.

[0072] Specifically, the connector housing 1 is also provided with a protruding post 12 on the same side wall as the limiting groove 13. A positioning element 35 is fitted on the protruding post 12 to further enhance the installation effect of the dust cover 3. One end of the positioning element 35 is provided with a first cable portion 351, the other end is provided with a second cable portion 352, and the middle is provided with a connecting body 353 for connecting the first cable portion 351 and the second cable portion 352.

[0073] The first cable portion 351 is fitted onto the protrusion 33, while the second cable portion 352 is fitted onto the protrusion 12. Specifically, when the first cable portion 351 is not fitted onto the protrusion 33, the positioning member 35 can rotate with the protrusion 12 as a fulcrum through the connection between the second cable portion 352 and the protrusion 12. That is, the positioning member 35 serves not only to increase the connection strength of the dust cover 3, but also to prevent the dust cover 3 from being lost after being dislodged from the limiting groove 13 by external force, remaining on the connector.

[0074] Example 5

[0075] Reference Figures 13-15 Based on one or more of the four schemes of Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4, the upper part of the connector housing 1 is also provided with a positioning spring 4. In particular, the connector housing 1 is also provided with a mounting groove 14 for installing the positioning spring 4.

[0076] Specifically, the mounting groove 14 includes a main groove body 141 and a first side groove 142 and a second side groove 143 disposed on the left and right sides of the main groove body 141. In this embodiment, the first side groove 142 and the second side groove 143 are located on the left and right sides of the main groove, but in practice, it is sufficient for the first side groove 142 and the second side groove 143 to be located on the sides of the main groove respectively. That is, the first side groove 142 and the second main groove can also be disposed on the upper and lower sides, diagonal sides, etc. of the main groove.

[0077] The main function of the first side groove 142 and the second side groove 143 is to hold the positioning spring 4. The positioning spring 4 includes a limiting foot 41 and an elastic locking part 42. The limiting foot 41 is located at both ends of the elastic locking part 42 to cooperate with the first side groove 142 and the second side groove 143 to limit the elastic locking part 42.

[0078] Furthermore, both the first side groove 142 and the second side groove 143 are connected to the main groove, and the elastic snap-fit ​​part 42 and the limiting foot 41 are an integral structure, that is, the positioning spring piece 4 is a piece of metal sheet bent into shape.

[0079] Specifically, the elastic snap-fit ​​part 42 also includes a connecting piece 421 and a first limiting side 422, a second limiting side 423, a third limiting side 424, and a fourth limiting side 425. The first limiting side 422, the second limiting side 423, the third limiting side 424, and the fourth limiting side 425 are distributed in a rhomboid structure, and the first limiting side 422, the second limiting side 423, the third limiting side 424, and the fourth limiting side 425 are connected end to end in sequence.

[0080] Specifically, the angle between the extensions of the first limiting side 422 and the fourth limiting side 425 is an acute angle, and the angle between the extensions of the second limiting side 423 and the third limiting side 424 is an obtuse angle. The first limiting side 422 and the second limiting side 423 are connected to form a first arc-shaped abutment section 426, and the third limiting side 424 and the fourth limiting side 425 form a second arc-shaped abutment section 427. That is, when the elastic locking part 42 is inserted into the groove on the back of the meter, the first arc-shaped abutment section 426 and the second arc-shaped abutment section 427 abut against the two sides of the groove to form an outward horizontal pressure, thereby assisting in positioning the meter.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
