Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment, in particular to a metering terminal box. BACKGROUND

[0002] The metering terminal box is a special terminal box in the standard terminal box of the electric energy metering device, and is also applicable to the secondary circuit with a rated voltage of 660 volts and a rated current of 20A, and is used for safely replacing or on-site inspecting the electric energy meter, electrical instrument, leakage protection and other electrical equipment under the condition of load, thereby ensuring the personal operation safety and improving the on-site work efficiency. The current metering terminal is fixedly connected by a single small wire screw, and the operation is cumbersome, the safety is poor, and errors are prone to occur. The metering terminal and quality of foreign countries are good, and the safety is high, but the installation is still cumbersome and errors are prone to occur.

[0003] In the prior art, patent No. CN103199470B discloses a metering terminal box which can effectively solve the problems of wire disconnection and breakage during connection, and ensure the safe operation of the power line, comprising a box body, a box cover, a conductive sheet and a locking mechanism. The inside of the box body is divided into a plurality of wire connection cavities by a longitudinal partition plate, a boss is arranged in the middle of each wire connection cavity, a hinge seat is arranged on the left and right sides of the front and rear parts of each wire connection cavity, respectively, and a wire connection hole is formed in the front and rear sidewalls of the box body corresponding to each wire connection cavity; a sleeve hole adapted to the boss is formed in the middle of each conductive sheet, and the conductive sheet is arranged at the bottom of each wire connection cavity one by one; the locking mechanism comprises a gate valve, a spring and a baffle, each gate valve comprises a pressing hand, a valve block and a hinge shaft, and the gate valve is installed at the front and rear parts of each wire connection cavity of the box body; the spring is embedded between the pressing hand of each gate valve and the boss; a pressing hand hole is formed in the front and rear parts of each baffle corresponding to the pressing hand of the gate valve, and the middle of each baffle is installed on the boss by a screw.

[0004] The above technical solution uses an elastic structure to connect the wires, but when the wire is inserted into the wire connection hole, it is inconvenient to judge the specific position of the wire, and both hands need to be operated.

[0047] As Figures 1 to 7As shown, the present application provides a metering terminal box, which comprises a shell 100, a mounting seat 200, a clasp 300, a driving member and a triggering member 400. The shell 100 is provided with a terminal hole 121 along a first direction X. The mounting seat 200 is fixed in the shell 100 and comprises a clamping part 210, which comprises a plurality of clamping pieces 211 uniformly arranged around a first axis. The clamping piece 211 comprises a first end 211a and a second end 211b arranged at intervals along the first direction X. The first ends 211a of all the clamping pieces 211 are relatively fixed. The clamping piece 211 can be elastically deformed. The second end 211b always has a tendency to move away from the first axis. The terminal hole 121 corresponds to the mounting seat 200 one by one. The clasp 300 is sleeved outside the mounting seat 200. The driving member can drive the clasp 300 to move relative to the mounting seat 200 along the first direction X to switch between a release position and a locking position. When the clasp 300 moves to the release position, the second end 211b moves away from the first axis. When the clasp 300 moves to the locking position, the second end 211b moves close to the first axis. The triggering member 400 is inserted into the mounting seat 200. The wire harness is inserted into the mounting seat 200 from the terminal hole 121. The wire harness can activate the driving member through the triggering member 400, so that the clamping piece 211 clamps the periphery of the wire harness. The first axis is parallel to the first direction X.

[0048] Specifically, the plurality of clamping pieces 211 enclose a terminal cavity around the first axis. The second end 211b of the clamping piece 211 encloses an inlet of the terminal cavity, and the inlet is opposite to the terminal hole 121. The release position of the clasp 300 is arranged close to the first end 211a of the clamping piece 211. The locking position of the clasp 300 is arranged close to the second end 211b of the clamping piece 211. Generally, the initial position of the clasp 300 is located at the release position. The second end 211b of the clamping piece 211 is in a release state, and both are away from the first axis. The inlet of the terminal cavity has a relatively large opening degree at this time, which is convenient for the wire harness to be inserted. After the wire harness is inserted into the terminal hole 121 along the first direction X and extends into the terminal cavity, the wire harness is inserted to a predetermined position. The clasp 300 is driven to move from the release position to the locking position. Since the inner diameter of the clasp 300 is constant and smaller than the diameter of the inlet formed by the clamping piece 211 in the release state, as the clasp 300 moves close to the second end 211b of the clamping piece 211, the clamping piece 211 is gathered to the first axis under the constraint of the clasp 300 and clamps the periphery of the wire harness, thereby completing the locking of the wire harness and maintaining the relative position between the wire harness and the shell 100.

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

[0050] Since the clamping portion 210 of the mounting seat 200 has the locking state for the wire harness and the releasing state for the wire harness, it is necessary to switch between the two states by deformation, which makes it difficult to set a support on the clamping portion 210 and the housing 100 is always arranged in a spaced manner, i.e., in a cantilever structure, and the stability is poor.

[0051] Therefore, in the embodiment, the peripheral side wall of the bundle 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 bundle ring 300, i.e., the deformation of the clamping portion 210 is not affected, and the stability of the clamping portion 210 is enhanced.

[0052] Optionally, the trigger piece 400 includes a rod portion 410 and a plurality of elastic sheet portions 420 formed on the peripheral side of the rod portion 410, the elastic sheet portions 420 can be elastically deformed, the mounting seat 200 further includes a limiting portion 220, the first end 211a of the clamping piece 211 is connected with the limiting portion 220, the limiting portion 220 is provided with a first limiting hole 221, the bundle ring 300 is provided with a second limiting hole 321, the trigger piece 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, when the trigger piece 400 is in the first position, the elastic sheet portions 420 are inserted into the first limiting hole 221 and the second limiting hole 321, and the bundle ring 300 is in the releasing position; when the trigger piece 400 is in the second position, the elastic sheet portions 420 are inserted into the first limiting hole 221 and are withdrawn from the second limiting hole 321, and the bundle ring 300 can move to the locking position.

[0053] Specifically, the initial position of the trigger piece 400 is located at the first position, and the bundle ring 300 is located at the releasing position, and the second ends 211b of the clamping pieces 211 are away from each other, so as to facilitate 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 piece 400, the trigger piece 400 is driven from the first position to the second position, the elastic sheet portions 420 of the trigger piece 400 abut against the side wall of the first limiting hole 221 of the mounting seat 200 and are elastically deformed, the elastic sheet portions 420 are tilted to one side of the second ends 211b of the clamping pieces 211 and are withdrawn from the second limiting hole 321 of the bundle ring 300, the bundle ring 300 can move from the releasing position to the locking position under the constraint of the trigger piece 400, and the clamping pieces 211 are close to the first axis under the gathering action of the bundle ring 300 and are clamped on the peripheral side of the wire harness. When it is necessary to release the wire harness from the clamping portion 210, the bundle ring 300 is pushed along the first direction X, so that the elastic sheet portions 420 of the trigger piece 400 are reinserted into the second limiting hole 321.

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

[0055] Thus, when the bundle ring 300 is in its release position and the clamping portion 210 is in the release state, the elastic member 500 is elastically deformed and in an energy storage state, always giving the bundle ring 300 an action force in the first direction X to the second end 211b, so that the bundle ring 300 always has a tendency to move from its release position to the locking position, i.e., from the first end 211a to the second end 211b of the clamping piece 211. When the bundle ring 300 is in the release position, the trigger member 400 is in its first position, and the elastic portion is inserted into the first limiting hole 221 and the second limiting hole 321, maintaining the relative position of the bundle ring 300 and the mounting seat 200, and limiting the elastic member 500 to recover the deformation; when the wire harness abuts against the rod portion 410 of the trigger member 400 in the first direction X and pushes the trigger member 400 from its first position to the second position, the elastic sheet portion 420 of the trigger member 400 abuts against the limiting portion 220 of the mounting seat 200 and is elastically deformed to bend away from the limiting portion 220, and then the elastic sheet portion 420 exits the second limiting hole 321, loses the limiting of the elastic sheet portion 420, and the elastic member 500 recovers the deformation to drive the bundle ring 300 to its locking position, and all the clamping pieces 211 are simultaneously constrained by the bundle ring 300 to concentrate towards the first axis and clamp the wire harness, and switch to the locking state. When it is needed to reset the bundle ring 300 to the release position, it is only needed to push the bundle ring 300 towards the first end 211a of the clamping piece 211 in the first direction X until the elastic portion of the trigger member 400 reinserts into the second limiting hole 321, and the elastic member 500 reenters the energy storage state.

[0056] In other embodiments, the driving member is an electric rod, a driving rod, a screw block mechanism, or the like, which can realize linear reciprocating movement. Thus, the trigger member 400 can be a trigger switch, which is electrically connected or communicatively connected with the driving member. When the wire harness collides with the trigger switch in the first direction X, the trigger switch activates the driving member to start and drive the bundle ring 300 to move to the locking position.

[0057] In other embodiments, the bundle ring 300 is arranged in the mounting seat 200, the clamping portion 210 includes n clamping pieces 211, and the bundle ring 300 is connected with the n clamping pieces 211 through n connecting rods, which are in one-to-one correspondence with the clamping pieces 211, one end of each connecting rod is hinged with a clamping piece 211, and the other end is hinged with the bundle ring 300. In this embodiment, when the bundle ring 300 is close to the first end 211a of the clamping piece 211, it is in the locking position, and the bundle ring 300 pulls the clamping piece 211 to gather towards the first axis through the connecting rod; when the bundle ring 300 is close to the second end 211b of the clamping piece 211, it is in the release position, and since the two ends of the connecting rod are close to each other in the first direction X, the connecting rod lifts the clamping piece 211 to make the second end 211b of the clamping piece 211 away from the first axis.

[0058] Optionally, the mounting base 200 comprises a first abutting portion 230, the first abutting portion 230, the limiting portion 220 and the clamping portion 210 are sequentially connected along the first direction X, the bundle ring 300 comprises a second abutting portion 310 and a sleeving portion 320 which are fixedly connected with each other, and the elastic member 500 is a spring, the elastic member 500 is partially sleeved on the sleeving portion 320, and the elastic member 500 is clamped between the first abutting portion 230 and the second abutting portion 310.

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

[0060] Optionally, the elastic sheet portion 420 comprises a first bending section 421 and a second bending section 422, the clamped angle between the first bending section 421 and the second bending section 422 is α, which satisfies 0 < α < 180, and the opening of the clamped angle faces the first abutting portion 230, the first bending section 421 is connected with 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 bundle ring 300 moves from the locking position to the release position, one side wall of the second limiting groove close to the first end 211a of the clamping piece 211 first abuts against the second bending section 422 of the trigger member 400, after the second bending section 422 is subjected to the acting force, the second bending section 422 elastically deforms and bends to one side of the first bending section 421, α decreases, and the side wall is avoided, when the second limiting hole 321 passes, the elastic sheet portion 420 restores the deformation due to the loss of abutment, the second bending section 422 rotates away from the first bending section 421, α restores, and the second bending section 422 is reinserted into the second limiting hole 321, so as to facilitate the movement of the bundle ring 300 from the locking position to the release position. Further, when the bundle ring 300 is in the release position, the elastic member 500 always acts on the bundle ring 300, so that the bundle ring 300 always has a tendency to move to the locking position, at this time, in order to prevent the elastic sheet 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 and have relatively strong resistance to reverse deformation, that is, the second bending section 422 is not easy to bend with the first bending section 421 under the action of the force directed to the second end 211b side along the first direction X.

[0062] Optionally, the second bending section 422 is provided with an inclined surface 4221, when the bundle ring 300 moves to the side of the first end 211a of the clamping piece 211 and abuts against the second bending section 422, the inclined surface 4221 can make the elastic sheet part 420 have a tendency to bend to the side of the rod part 410.

[0063] Specifically, the inclined surface 4221 is arranged on the side of the second bending section 422 opposite to the first abutting part 230 in the first direction X, the inclined surface 4221 and the first axis are arranged at an acute angle, and the opening direction of the acute angle is towards the first abutting part 230. When the bundle ring 300 moves from the locking position to the release position, the inclined surface 4221 can convert the force in the first direction X into a force in the direction of the rod part 410 of the trigger piece 400, so that the second bending section 422 bends towards the first bending section 421.

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

[0065] Specifically, in the second direction Y, an installation groove is formed between the two adjacent limiting columns 130, the mounting seat 200 is installed in the installation groove, and the two side walls of the mounting seat 200 in the second direction Y abut against the two limiting columns 130 on the two sides respectively, that is, the mounting seat 200 is clamped between the two adjacent limiting columns 130.
