Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a metering junction box. Background Art

[0002] The metering junction box is a special junction box in the standard junction box of the electric energy metering device. It is also suitable for secondary circuits with a rated voltage of 660 volts and a rated current of 20A. It is used for safe replacement or on-site inspection of electric energy meters, electrical instruments, leakage protection and other electrical equipment under load, ensuring personal operation safety and improving on-site work efficiency. At present, the metering wiring is fixed with a single small wire screw, which is cumbersome to operate, poor in safety, and prone to errors. Foreign metering wiring is of good quality and high safety, but it cannot fundamentally change the disadvantages of cumbersome installation and easy installation errors.

[0003] In the prior art, patent announcement number CN103199470B discloses a metering junction box that can effectively solve the problem of disconnection and disconnection during wiring and ensure the safe operation of power lines, including a box body, a box cover, a conductive sheet and a locking mechanism. The interior of the box body is divided into a plurality of wiring chambers by a longitudinal partition, a boss is arranged in the middle of each wiring chamber, a hinge seat is arranged on the left and right sides of the front and rear parts of each wiring chamber respectively, and a wiring hole is opened on the front and rear side walls of the box body respectively corresponding to each wiring chamber; a sleeve hole adapted to the boss is opened in the middle of each conductive sheet, and the conductive sheets are arranged one by one at the bottom of each wiring chamber; the locking mechanism includes a gate valve, a spring and a baffle, each gate valve includes a hand, a valve block and a hinge shaft, and the gate valve is installed at the front and rear parts of each wiring chamber of the box body; the spring is embedded between the hand and the boss of each gate valve; a hand hole is opened in the front and rear parts of each baffle respectively corresponding to the hand of the gate valve, and the middle part of each baffle is installed on the boss by screws.

[0004] The above technical solution adopts an elastic structure to connect the wires, but in actual use, when the wires are inserted into the wiring holes, it is not easy to judge the specific position of the wires, and both hands are required to operate. If the wires are released after being inserted, the wires will be pulled out of the wiring holes under the action of their own gravity or elastic force, which may lead to the possibility of a false connection in the wire connection.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] like Figures 1 to 7As shown, the present invention provides a metering junction box, including a shell 100, a mounting seat 200, a clamping ring 300, a driving member and a trigger member 400. The shell 100 is provided with a wiring hole 121 along the first direction X; the mounting seat 200 is fixed in the shell 100, and the mounting seat 200 includes a clamping portion 210, and the clamping portion 210 includes a plurality of clips 211, and the plurality of clips 211 are evenly arranged around the first axis. The clips 211 include a first end 211a and a second end 211b spaced apart in the first direction X, and the first ends 211a of all the clips 211 are relatively fixed, and the clips 211 can undergo elastic deformation, and the second ends 211b always have a tendency to move to a side away from the first axis, and the wiring holes 121 are one-to-one with the mounting seat 200. The clamping ring 300 is sleeved on the outside of the mounting seat 200, and the driving member can drive the clamping ring 300 to move relative to the mounting seat 200 along the first direction X to switch the release position and the locking position. When the clamping ring 300 moves toward the release position, the second end 211b is away from the first axis. When the clamping ring 300 moves toward the locking position, the second end 211b is close to the first axis. The trigger member 400 is inserted into the mounting seat 200, and the wiring harness self-wiring hole 121 is inserted in the mounting seat 200. The wiring harness can activate the driving member through the trigger member 400, so that the clip 211 is clamped on the surrounding side of the wiring harness. The first axis is parallel to the first direction X.

[0048] Specifically, a plurality of clips 211 surround the first axis to form a wiring cavity, and the second end 211b of the clip 211 surrounds the entrance of the wiring cavity, and the entrance is directly opposite to the wiring hole 121. The release position of the tie ring 300 is set to a side close to the first end 211a of the clip 211, and the locking position of the tie ring 300 is set to a side close to the second end 211b of the clip 211. Generally, the initial position of the tie ring 300 is at its release position, and the second end 211b of the clip 211 is in a released state, both away from the first axis. At this time, the entrance of the wiring cavity is relatively open, which is convenient for wiring harness insertion. After the wiring harness passes through the wiring hole 121 along the first direction X, it extends into the wiring cavity. After the wiring harness is inserted into the preset position, the driving ring 300 moves from the release position to the locking position. Since the inner diameter of the ring 300 is constant and the inner diameter of the ring 300 is smaller than the diameter of the inlet formed by the clip 211 in the released state, as the ring 300 approaches the second end 211b of the clip 211, the clip 211 gathers toward the first axis under the constraint of the ring 300, and is clamped on the surrounding side of the wiring harness, thereby completing the locking of the wiring harness and maintaining the relative position between the wiring harness and the housing 100.

[0049] It should be noted that the clip 211 is made of elastic conductive metal material, and the mounting seat 200 is made of conductive material.

[0050] Since the clamping portion 210 of the mounting seat 200 has a locking state for the wire harness and a releasing state for the wire harness, it needs to switch between the two states through deformation, which makes it difficult to provide support for the clamping portion 210. The clamping portion 210 is always spaced apart from the housing 100, i.e., it is a cantilever structure with poor stability.

[0051] Therefore, in this embodiment, the peripheral side wall of the clamping ring 300 is supported between the mounting seat 200 and the bottom of the housing 100. In this way, the clamping portion 210 is supported by the clamping ring 300, which does not affect the deformation of the clamping portion 210 and can enhance the stability of the clamping portion 210.

[0052] Optionally, the trigger member 400 includes a rod portion 410 and a spring piece portion 420, and the spring piece portion 420 is formed with multiple spring pieces 420 on the circumferential side of the rod portion 410. The spring piece portion 420 can undergo elastic deformation, and the mounting seat 200 also includes a limiting portion 220. The first end 211a of the clip 211 is connected to the limiting portion 220. The limiting portion 220 is provided with a first limiting hole 221. The clamping ring 300 includes a second limiting hole 321. The trigger member 400 is inserted into the mounting seat 200 and can move relative to the mounting seat 200 along the first direction X to switch between the first position and the second position. The trigger member 400 is in the first position, the spring piece portion 420 is inserted into the first limiting hole 221 and the second limiting hole 321, and the clamping ring 300 is in the release position; the trigger member 400 is in the second position, the spring piece portion 420 is inserted into the first limiting hole 221, and withdraws from the second limiting hole 321, and the clamping ring 300 can move to the locking position.

[0053] Specifically, the initial position of the trigger member 400 is at its first position, the tie ring 300 is at the release position, and the second ends 211b of the clips 211 are away from each other, which facilitates the insertion of the wire harness. When the wire harness is inserted into the mounting seat 200 along the first direction X and abuts against the trigger member 400, and the trigger member 400 is driven from its first position to the second position, the spring sheet portion 420 of the trigger member 400 abuts against the side wall of the first limiting hole 221 of the mounting seat 200 and undergoes elastic deformation, and the spring sheet portion 420 tilts toward the second end 211b of the clip 211 and withdraws from the second limiting hole 321 of the tie ring 300, and loses the constraint of the trigger member 400. The tie ring 300 can move from its release position to the locking position, and the clip 211 is close to the first axis under the gathering effect of the tie ring 300, and is clamped on the peripheral side of the wire harness. When the clamping portion 210 is required to release the wire harness, the clamping ring 300 is pushed along the first direction X so that the spring portion 420 of the triggering member 400 is re-inserted into the second limiting hole 321 .

[0054] Optionally, the driving member is an elastic member 500 , and the elastic member 500 is sandwiched between the mounting seat 200 and the clamping ring 300 , so that the clamping ring 300 always has a tendency to move from the first end 211 a to the second end 211 b .

[0055] In this way, when the clamping ring 300 is in its release position and the clamping portion 210 is in a released state, the elastic member 500 undergoes elastic deformation and is in an energy storage state, always applying a force along the first direction X to the second end 211b to the clamping ring 300, so that the clamping ring 300 always has a tendency to move from its release position to the locking position, that is, to move from the first end 211a of the clamp 211 to the second end 211b. When the clamping ring 300 is in the release position, the trigger member 400 is in its first position, and the elastic part is inserted into the first limiting hole 221 and the second limiting hole 321 to maintain the relative position of the clamping ring 300 and the mounting seat 200, and limit the elastic member 500 from restoring the deformation; when the wiring harness abuts against the rod 410 of the trigger member 400 along the first direction X and pushes the trigger member 400 from its first position to the second position, the spring sheet part 420 of the trigger member 400 abuts against the limiting part 220 of the mounting seat 200, and causes the spring sheet part 420 to undergo elastic deformation and bend to the side opposite to the limiting part 220, thereby causing the spring sheet part 420 to withdraw from the second limiting hole 321, lose the limiting position of the spring sheet part 420, and the elastic member 500 restores the deformation, driving the clamping ring 300 to its locking position, and all the clips 211 are constrained by the clamping ring 300 at the same time, concentrate toward the first axis, clamped on the peripheral side of the wiring harness, and switched to the locked state. When the cinch ring 300 needs to be reset to the release position, the cinch ring 300 only needs to be pushed along the first direction X toward the first end 211a of the clip 211 until the elastic portion of the trigger member 400 is reinserted into the second limiting hole 321, and the elastic member 500 resumes the stored force state.

[0056] In other embodiments, the driving member is a structure capable of realizing linear reciprocating movement, such as an electric rod, a driving rod, a lead screw slider mechanism, etc. In this case, the trigger member 400 can be a trigger switch, which is electrically connected or communicatively connected to the driving member. When the wire harness touches the trigger switch along the first direction X, the trigger switch activates the driving member to start and drive the tie ring 300 to move to the locking position.

[0057] In other embodiments, the clamping ring 300 is arranged in the mounting base 200, the clamping portion 210 includes n clips 211, and the clamping ring 300 is connected to the n clips 211 through n connecting rods, the connecting rods correspond to the clips 211 one by one, one end of the connecting rod is hinged to the clip 211, and the other end is hinged to the clamping ring 300. In this embodiment, when the clamping ring 300 is close to the first end 211a of the clip 211, it is in a locked position, and the clamping ring 300 pulls the clip 211 to gather toward the first axis through the connecting rod; when the clamping ring 300 is close to the second end 211b of the clip 211, it is in a released position. Since the two ends of the connecting rod are close to each other in the first direction X, the connecting rod lifts the clip 211, so that the second end 211b of the clip 211 is away from the first axis.

[0058] Optionally, the mounting seat 200 includes a first abutment portion 230, the first abutment portion 230, the limiting portion 220 and the clamping portion 210 are connected in sequence along the first direction X, the clamping ring 300 includes a second abutment portion 310 and a sleeve portion 320 that are fixed to each other, the elastic member 500 is a spring, the elastic member 500 is partially sleeved on the sleeve portion 320, and the elastic member 500 is clamped between the first abutment portion 230 and the second abutment portion 310.

[0059] Specifically, the cinch ring 300 is a trapezoidal shaft structure, including a large diameter section and a small diameter section, and a shoulder formed between the large diameter section and the small diameter section, wherein the large diameter section is the second abutting portion 310, and the small diameter section is the sleeve portion 320. The elastic member 500 is a spring, and its main elastic deformation direction is its axial direction. The elastic member 500 is sleeved on the sleeve portion 320, and one axial end thereof abuts against the shoulder, and the other end abuts against the second abutting portion 310. The sleeve portion 320 can provide partial support for the elastic member 500, regulate its deformation direction, and maintain the relative position of the elastic member 500 and the cinch ring 300. The arrangement of the first abutting portion 230 and the second abutting portion 310 makes the force direction of the elastic member 500 consistent with the movement direction of the cinch ring 300 relative to the mounting seat 200.

[0060] Optionally, the spring portion 420 includes a first bending section 421 and a second bending section 422, the first bending section 421 and the second bending section 422 are provided at an angle α, satisfying 0<α<180, and the opening of the angle faces the first abutting portion 230, the first bending section 421 is connected to the rod portion 410, and the second bending section 422 can be inserted into the first limiting hole 221 and / or the second limiting hole 321.

[0061] In this way, when the clamping ring 300 moves from its locking position to the release position, a side wall of the second limiting groove close to the first end 211a of the clip 211 first abuts against the second bending section 422 of the trigger member 400. After the second bending section 422 is subjected to the force, it undergoes elastic deformation and bends toward the first bending section 421, α is reduced, and the side wall is avoided. When the second limiting hole 321 passes, the spring sheet portion 420 loses its abutment effect, and the second bending section 422 rotates toward the side away from the first bending section 421, α is restored, and the second bending section 422 is reinserted into the second limiting hole 321, thereby facilitating the clamping ring 300 to move from its locking position to the release position. Furthermore, when the clamping ring 300 is in the release position, the elastic member 500 always acts on the clamping ring 300, so that the clamping ring 300 always has a tendency to move to the locking position. At this time, in order to prevent the spring portion 420 from elastically deforming under the action of the elastic member 500, the first bending section 421 and the second bending section 422 form a bow shape, which has a relatively strong ability to resist reverse deformation, that is, it is not easy for the second bending section 422 and the first bending section 421 to bend under the force along the first direction X pointing to the side of the second end 211b.

[0062] Optionally, the second bending section 422 is provided with an inclined surface 4221 , and when the clamp ring 300 moves toward the first end 211a of the clip 211 and abuts against the second bending section 422 , the inclined surface 4221 can make the spring portion 420 have a tendency to bend toward the rod portion 410 .

[0063] Specifically, the inclined surface 4221 is disposed on a side of the second bending section 422 that is opposite to the first abutting portion 230 in the first direction X. The inclined surface 4221 and the first axis form an acute angle, and the opening direction of the acute angle faces the first abutting portion 230. When the cinch ring 300 moves from its locking position to the releasing position, the inclined surface 4221 can convert a portion of the force along the first direction X into a force pointing in the direction of the rod portion 410 of the trigger member 400, so that the second bending section 422 bends toward the first bending section 421.

[0064] Optionally, a plurality of limiting posts 130 are disposed in the housing 100 , and in the second direction Y, the plurality of limiting posts 130 and the plurality of mounting seats 200 are arranged alternately; the first direction X and the second direction Y are perpendicular.

In this way, the limiting columns 130 can limit the movement of the mounting seat 200 relative to the housing 100 in the second direction Y, and the friction between the limiting columns 130 and the mounting seat 200 can limit the movement of the mounting seat 200 relative to the housing 100 in the first direction X.

[0066] It should be noted that, since the clamping portion 210 of the mounting seat 200 needs to be deformed, the first abutting portion 230 of the mounting seat 200 is clamped between two adjacent limiting columns 130 .

[0067] Optionally, the shell 100 includes an end cover 110 and a shell body 120, the end cover 110 and the shell body 120 are detachably connected in a third direction Z, the limiting column 130 is fixed to the shell body 120, the end cover 110 is fixed with a pressure block 140, a plurality of pressure blocks 140 are provided, and the pressure blocks 140 and the limiting columns 130 are arranged alternately along the second direction Y, and the pressure blocks 140 can abut against the first abutment portion 230 along the third direction Z; the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0068] Specifically, the end cover 110 and the shell 100 can be disassembled so that the mounting seat 200 is exposed, which is convenient for loading and unloading the mounting seat 200. During assembly, the first abutting portion 230 of the mounting seat 200 is first placed in the mounting groove formed by two adjacent limiting columns 130 to complete the limiting in the first direction X, and then the end cover 110 is buckled, and the pressing block 140 abuts against the first abutting portion 230 along the third direction Z. The first abutting portion 230 is sandwiched between the end cover 110 and the shell body 120 in the third direction Z. In this way, the movement of the mounting seat 200 relative to the shell 100 in the third direction Z can be limited, and the friction force formed by the extrusion can also limit the movement of the mounting seat 200 relative to the shell 100 in the first direction X.

[0069] Optionally, two mounting seats 200 are placed between two adjacent limiting columns 130, and the two mounting seats 200 are mirror-imaged along the first direction X, and the clamping portions 210 are arranged opposite to each other. Such an arrangement can increase the number of connections that can be made to the metering junction box, and can avoid mutual interference between two adjacent mounting seats 200 in the first direction X.
