DETAILED DESCRIPTION

[0046] The technical solutions of the present application will be described clearly and completely below in conjunction with embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] Embodiment 1

[0048] AsFigures 1-4 The rotary connector assembly and the electric meter connector shown are intended to solve the problem that the conventional electric meter connector plug-in module is provided with a protruding rotating shaft on both sides, and the rotation power-off is realized by the shell 222 which can rotate with the protrusion. This structure occupies more space on both sides of the contact group and is not conducive to the additional installation of the indication assembly 213, and only two protruding shafts are used as rotation support points, the structural strength is low, and the replacement cannot be realized after the fracture.

[0049] Specifically, the electric meter connector of the utility model comprises a connector shell 1 and a connector assembly 2, and the connector assembly 2 is mainly composed of a rotating mechanism 22 and a conductive mechanism 21. The connector assembly 2 can realize power-off and closing operation by rotating the rotating mechanism 22. In particular, the conductive mechanism 21 comprises four static contact pieces 211, i.e. conductive rows and conductive terminals 212, and the rotating mechanism 22 is composed of four connecting columns 221 matched with the static contact pieces 211 and a shell 222 containing the connecting columns 221. That is, the static contact pieces 211 and the connecting columns 221 correspond to each other one by one, and one connecting column 221 is used to match one static contact piece 211. The connecting column 221 is used to connect the power measurement device, for example, the electric energy meter, the voltmeter, the power factor meter and the like.

[0050] Further, the shell 222 is further provided with a positioning block 2222, and the connector shell 1 is provided with a positioning groove 11 matched with the positioning block 2222, and the two form a buckle 34 relationship of mutual clamping. In the embodiment, the number of the positioning block 2222 is two, and is respectively arranged at the top of the two ends of the shell 222, and the number and position of the positioning groove 11 correspond to each other with the positioning block 2222. When the rotating mechanism 22 is closed and in the conductive state, the positioning block 2222 is connected with the positioning groove 11 to form a limiting structure. In particular, in order to increase the mechanical strength of the positioning block 2222, the bottom of the positioning block 2222 is further provided with a reinforcing rib 2223.

[0051] The bottom of each static contact piece 211 is independently provided with a conductive terminal 212 for connecting the wires or connectors of the external circuit, and the conductive terminal 212 is a common knowledge of those skilled in the art, which will not be described here. The left and right sides of the upper part of the static contact piece 211 are provided with a limiting arm 2111 extending to the same side, and the limiting arm 2111 and the static contact piece 211 are an integral structure, and the two limiting arms 2111 are used to clamp the connecting column 221 to realize the circuit conduction, and if power-off is required, the connecting column 221 and the clamping arm are separated.

[0052] Reference Figures 5-6In order to design the replaceable rotating shaft 2233 under the premise of saving space and increasing rotating intensity, the connector assembly 2 is detachably provided with a rotating assembly 223 on the static contact 211, and the connecting column 221 is rotatably connected with the rotating assembly 223. That is, the connecting column 221 can rotate by taking the end connected with the rotating assembly 223 as a fulcrum, so as to realize the connection and separation between the connecting column 221 and the limiting arm 2111, and further realize the open circuit or conduction.

[0053] Specifically, the rotating assembly 223 is located between the limiting arm 2111 and the conductive terminal 212, the middle of the static contact 211 is provided with a rectangular insertion hole 2112, and the rotating assembly 223 is vertically inserted into the insertion hole 2112. The rotating assembly 223 comprises a rotating body 2231, an insertion piece 2232 and a rotating shaft 2233 inserted into the rotating body 2231, the bottom of the rotating body 2231 is provided with a limiting seat 22311, and the upper part of the rotating assembly 223 is provided with a rotating shaft 2233 hole for facilitating the insertion of the rotating shaft 2233 into the rotating body 2231. That is, in the embodiment, the rotating shaft 2233 is detachably inserted into the rotating body 2231, and the upper part of the rotating body 2231 described in the embodiment is the front part of the rotating body 2231, which will be described in detail in the following direction, and is not the actual position of the feature, the position is related to the angle of the component, and is not limited again. Figure 5 The front part of the rotating body 2231, the next part is described in detail in the direction of the figure, and is not the actual position of the feature, the position is related to the angle of the component, and is not limited again.

[0054] In the embodiment, the rotating shaft 2233 is provided on the rotating body 2231 by means of a latch, which is used for limiting the insertion piece 2232 and preventing it from moving outward. However, under the premise of meeting certain lightweight design and improving economic benefits, the rotating shaft 2233 can also be an integral structure with the rotating body 2231.

[0055] Referring to Figures 7-8The top post 2214 is movably arranged in the connecting post 221. When the rotating assembly 223 is inserted into the static 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 is arranged perpendicularly to the side surface of the rotating body 2231. At this time, the connector is in a conducting state. With the rotation of the rotating assembly 223, the bottom of the top post 2214 slides along the outside of the rotating body 2231. In particular, the front end of the rotating body 2231 and the contact piece 2232 are further provided with a groove 22312, and the groove 22312 is provided with an arc transition surface 22313 between the side surface of the rotating body 2231 and the contact piece 2232. The arc transition surface 22313 includes an end point a and an end point b. When the top post 2214 is located between the end point a and the side surface of the rotating body 2231, the connector is in a conducting state. When the top post 2214 is located between the end point a and the end point b, the rotating assembly 223 is in a state of being separated, and at this time, the rotating assembly 223 and the connector shell 1 are between 90° and 60°. When the top post 2214 is located in the groove 22312, the connector is in a disconnected state.

[0056] In particular, the groove 22312 includes a limiting portion 22315, that is, the lowest point of the groove 22312. When the top post 2214 is located in the limiting portion 22315 of the groove 22312, the connector is in a disconnected state. The groove 22312 is in a V-shaped structure as a whole, the front end of the contact piece 2232 is similar in shape to the front end of the rotating body 2231, and when the contact piece 2232 is inserted into the rotating body 2231, the end surface thereof is in the same horizontal plane as the end surface of the rotating body 2231.

[0057] 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 contact piece 2232, and the movable range of the top post 2214 is on the side surface of the contact piece 2232, that is, the side surface of the contact piece 2232 is tangent to the spherical portion 22141, regardless of whether the rotating assembly 223 is in a conducting state or a disconnected state. The contact piece 2232 is arranged to prevent the top post 2214 from directly contacting the rotating body 2231 and thereby causing wear on the surface of the rotating body 2231, which would cause the top post 2214 to move with errors and affect the connection effect of the electric meter. In particular, in this embodiment, the contact piece 2232 is made of metal, such as copper, iron, aluminum or metal alloy, that is, the hardness of the contact piece 2232 should be greater than or equal to the hardness of the top post 2214, so as to prevent the contact piece 2232 from being directly worn on the side surface after the two are in contact.

[0058] Further, the connecting column comprises a connecting part 2212 cooperating with the rotating assembly 223, a connecting body 2213 cooperating with the limiting arm 2111, and a connector part 2211 for cooperating with the electric meter connector. In the embodiment, the connecting part 2212 is arranged below the connecting body 2213, and the connector part 2211 is arranged above the connecting body 2213.

[0059] The connector part 2211 is provided with a four-limb outwardly expandable head 22111. In particular, the distance between the center point of the rotating shaft 2233 and the top of the side surface of the insertion piece 2232 is x, and the distance between the center point of the rotating shaft 2233 and the lowest point of the recess 22312, i.e. the lowest point of the limiting part 22315, is y. In the present solution, in order to realize the upward movement of the top column 2214 and the outward expansion of the head 22111 when the connector is in the on state, and the downward movement of the top column 2214 to reset the head 22111 when the connector is in the off state, the length of y is less than the length of x. In the embodiment, the length of x is about 1.6 times the length of y.

[0060] Embodiment 2

[0061] With reference to Figures 9-10 As shown in the embodiment 1, the rotating mechanism 22 further comprises a short-circuit structure 224 mainly composed of two conductive blocks 2241. The shell 222 of the rotating mechanism 22 is provided with a clamping groove 2221 for clamping the conductive blocks 2241. When the rotating mechanism 22 is in the on state, the conductive blocks 2241 do not contact the limiting arms 2111. When the rotating mechanism 22 moves to the off state, the conductive blocks 2241 rotate together with the shell 222. When the rotating mechanism 22 is in the off state, the conductive blocks 2241 abut against the adjacent two static contact pieces 211, i.e. the adjacent two static contact pieces 211 are short-circuited.

[0062] In particular, when the connector is in the on state, the conductive blocks 2241 are located behind the static contact pieces 211, and one conductive block 2241 is arranged between the two groups of static contact pieces 211. In the embodiment 1, there are four static contact pieces 211, and in the present embodiment, there are two conductive blocks 2241. The conductive blocks 2241 are used to short-circuit the adjacent two static contact pieces 211, thereby realizing the short-circuiting between the adjacent two static contact pieces 211 and the uninterrupted replacement of the electric meter.

[0063] In order to realize the above-mentioned solution, the distance between the adjacent two static contact pieces 211 should be less than the width of the conductive block 2241. In the present embodiment, the conductive block 2241 is in a concave shape structure, and is in interference fit with the clamping groove 2221. The conductive block 2241 comprises a first conductive arm and a second conductive arm, and the first conductive arm and the second conductive arm respectively abut against the left and right static contact pieces 211.

[0064] In particular, once the conductive block 2241 is inserted into the slot 2221, it can be further reinforced with bolts.

[0065] Example 3

[0066] 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.

[0067] 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.

[0068] Example 4

[0069] 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.

[0070] 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.

[0071] The limiting groove 13 is arranged on the upper part of the connector housing 1. The dust cover 3 is fixed by clamping in the limiting groove 13, that is, when the dust cover 3 is not needed, the dust cover 3 can be clamped in the limiting groove 13 for storage or transportation, preventing loss.

[0072] The buckle 34 of the L-shaped structure in the middle part of the dust cover 3, specifically, the buckle 34 is arranged on the connecting belt 32 in the middle part of the dust cover 3, in order to facilitate the installation of the limiting, the shell 222 of the rotating mechanism 22 is also provided with the buckle 34 matched with the buckle 34. When the dust cover 3 is installed on the head 22111 of the connecting column 221, the buckle 34 is clamped in the buckle 2224 for auxiliary positioning.

[0073] Specifically, the connector housing 1 is also provided with a convex column 12 on the same side wall as the limiting groove 13, and the positioning member 35 is sleeved on the convex column 12 to further increase the installation effect of the dust cover 3. The positioning member 35 is provided with a first lasso part 351 at one end, a second lasso part 352 at the other end, and a connecting body 353 for connecting the first lasso part 351 and the second lasso part 352 in the middle.

[0074] The first lasso part 351 is sleeved on the convex block 33, and the second lasso part 352 is sleeved on the convex column 12. In particular, when the first lasso part 351 is not sleeved on the convex block 33, the positioning member 35 can be rotated by the connecting relationship between the second lasso part 352 and the convex column 12 with the convex column 12 as the fulcrum. That is, the positioning member 35 is used not only to increase the connecting strength of the dust cover 3, but also to prevent the dust cover 3 from being separated from the limiting groove 13 due to external force and still being on the connector, so as not to be lost.

[0075] Embodiment 5

[0076] Referring to Figures 13-15 On the basis of one or more combinations of the four schemes of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, the upper part of the connector housing 1 is also provided with a positioning spring 4, and specifically, the connector housing 1 is also provided with a mounting groove 14 for mounting the positioning spring 4.

[0077] Specifically, the mounting groove 14 includes a main groove body 141, and a first side groove 142 and a second side groove 143 arranged 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 fact as long as the first side groove 142 and the second side groove 143 are respectively located on the two sides of the main groove, that is, the first side groove 142 and the second main groove can also be arranged on the upper and lower sides, the diagonal sides, etc.

[0078] The main role of the first side groove 142 and the second side groove 143 is to clamp the positioning elastic sheet 4, which comprises a limiting foot 41 and an elastic clamping portion 42, and the limiting foot 41 is arranged at both ends of the elastic clamping portion 42 for limiting the elastic clamping portion 42 by cooperating with the first side groove 142 and the second side groove 143.

[0079] Further, the first side groove 142 and the second side groove 143 are in communication with the main groove, and the elastic clamping portion 42 and the limiting foot 41 are in an integral structure, that is, the positioning elastic sheet 4 is an integral bending forming of a metal sheet.

[0080] Specifically, the elastic clamping portion 42 further comprises a connecting sheet 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 in a rhombus structure and are sequentially connected in a head-to-tail manner.

[0081] Particularly, the first limiting side 422 and the fourth limiting side 425 form an acute angle, and the second limiting side 423 and the third limiting side 424 form an obtuse angle.
