DETAILED DESCRIPTION

[0031] Example one:

[0032] Please refer to Figures 1 to 5 , the embodiment of the present application provides a switching type high load electric energy meter, aiming at the wiring problem of the table body 1 during use, mainly used for realizing synchronous and rapid limiting of all wires. It specifically includes a table body 1, which is detachably connected with an end cap 2, the end cap 2 is designed in L shape and buckled on the table body 1; in this embodiment, the table body 1 is a switching type high load electric energy meter, which can stably and accurately measure and manage electric energy, the table body 1 itself and its detachable connection with the end cap 2 are all existing mature technologies, which will not be described in detail here.

[0033] Further, the bottom of the end cap 2 is provided with a threading hole 201 for the wire to pass through, the inside of the end cap 2 is provided with a sliding assembly 3 extending into the threading hole 201, the sliding assembly 3 can directly contact with the outer surface of the wire, and the front side of the end cap 2 is further provided with a limiting assembly 4 in transmission connection with the sliding assembly 3; in this embodiment, the number of the threading hole 201, the sliding assembly 3 and the limiting assembly 4 is four groups. When the wires are sequentially placed in the threading hole 201, the end cap 2 is pressed towards the table body 1, at this time, the outer surface of the wire can contact with the sliding assembly 3, so that the sliding assembly 3 is retracted into the end cap 2, and the sliding assembly 3 can drive the limiting assembly 4 to move when it is retracted along the end cap 2, so that the limiting assembly 4 tightly presses the wire.

[0034] In the above structure, the bottom of the table body 1 is provided with a step 101 for assembling the end cap 2, when the end cap 2 is assembled on the table body 1, the step 101 can make the end cap 2 coincide with the table body 1, avoiding the protrusion of the end cap 2 based on the table body 1. And when wiring, the moving direction of the wire based on the end cap 2 is perpendicular to the pressing assembly direction of the end cap 2 based on the step 101, one is from bottom to top, and the other is from front to back.

[0035] Referring to Figures 2 to 5In the embodiment, preferably, the sliding assembly 3 comprises a sliding rod 303 slidingly mounted on the end cover 2, one end of the sliding rod 303 is located in the wire hole 201 and fixedly mounted with a contact block 301 for directly contacting the wire in the wire hole 201, the other end of the sliding rod 303 is located in the end cover 2 and fixedly mounted with a flexible rack 302 in transmission connection with the limiting assembly 4. Wherein, the outer surface of the sliding rod 303 is sleeved with a first spring 304, under the action of the first spring 304, the sliding rod 303 has a tendency to approach the surface body 1.

[0036] Correspondingly, the inside of the end cover 2 is provided with a cavity 202 for the arrangement of the flexible rack 302, when the end cover 2 is pressed towards the surface body 1, the contact block 301 contacts the wire, at this time, the sliding rod 303 can be retracted into the cavity 202, thereby driving the flexible rack 302 to move along the cavity 202.

[0037] Referring to Figures 2 to 5 In the embodiment, preferably, the limiting assembly 4 comprises a rotating seat 401 rotatingly mounted on the end cover 2 and a pressing cylinder 402 sleeved outside the rotating seat 401, the outer surface of the rotating seat 401 is fixedly mounted with a gear 405 in transmission connection with the flexible rack 302; when the flexible rack 302 moves along the cavity 202, it can drive the gear 405 and the rotating seat 401 to rotate. Further, the outer surface of the rotating seat 401 is provided with an arc-shaped slot 403, the inside of the pressing cylinder 402 is fixedly mounted with a guide column 404 slidingly engaged in the arc-shaped slot 403, when the rotating seat 401 rotates, through the arc-shaped slot 403 and the guide column 404, the pressing cylinder 402 can be driven to vertically descend.

[0038] Wherein, in order to ensure the vertical descent of the pressing cylinder 402, an extension rod 406 can be fixedly mounted between the pressing cylinder 402 and the inner wall of the end cover 2. And the pressing cylinder 402 corresponds to the wire hole 201 in an up-down manner, when the pressing cylinder 402 moves based on the rotating seat 401, it can press the wire inserted from the wire hole 201.

[0039] Further, the surface of the rotating seat 401 away from the pressing cylinder 402 is provided with a cross slot, the cross slot is matched with the existing spoon and other tools, which is convenient for clamping and driving the rotating seat 401 to rotate, so as to realize the corresponding adjustment of one of the pressing cylinders 402.

[0040] In use, first, the plurality of wires to be connected are placed in the wire hole 201 of the end cover 2 in sequence, and the wires are in a state of extending into the surface body 1 (i.e., the wires are inserted into the wire hole 201 and correspond to the pressing cylinder 402 in an up-down manner); then, the end cover 2 is pressed towards the surface body 1, and the wires are attached to the surface body 1 by the contact block 301, and the attached wires cannot be moved so that the contact block 301 moves based on the direction of the end cover 2, at this time, the slide rod 303 is retracted into the end cover 2 and presses the first spring 304, and the slide rod 303 drives the flexible rack 302 to move synchronously when moving, the flexible rack 302 drives the rotating seat 401 to rotate through the gear 405, and the rotating seat 401 drives the pressing cylinder 402 to descend through the arc-shaped slot 403 and the guide column 404, and the pressing cylinder 402 can limit the wires inserted from the wire hole 201, and then the synchronous limiting of all the wires can be realized, and finally, the end cover 2 can be fixed on the surface body 1.

[0041] If subsequent maintenance or replacement of a single wire is needed, the screwdriver is only needed to be engaged with the cross slot to rotate and adjust the rotating seat 401, so that the pressing cylinder 402 is adjusted to ascend or descend along the rotating seat 401, so that the single wire is adjusted alone.

[0042] In the above process, when the end cover 2 is detachably connected to the surface body 1 by the screw, after the wires are placed in the wire hole 201, the screw can be directly rotated to assemble the end cover 2, and the screw drives the end cover 2 to automatically approach the surface body 1, at this time, the movement of the end cover 2 relative to the surface body 1 can automatically realize the automatic limiting of the plurality of wires, so that the step of pressing the end cover 2 towards the surface body 1 is omitted.

[0043] In summary, after the plurality of wires to be connected are placed in the wire hole 201 in sequence by the cooperation of the end cover 2, the contact block 301, the rotating seat 401 and the pressing cylinder 402, the wires can be contacted with the contact block 301 to move the flexible rack 302, and finally drive the pressing cylinder 402 to move to press the wires, so that the synchronous and rapid limiting of the plurality of wires can be realized, and the subsequent maintenance or replacement of a single wire is facilitated, the wiring efficiency of the plurality of wires can be effectively improved, and the labor burden of the workers can be significantly reduced; without using the wiring mode of tightening a plurality of bolts, the wiring steps of the plurality of wires can be effectively simplified, and the overall operation is simple and more practical.

[0044] Embodiment Two

[0045] Please refer to Figures 1 to 8 On the basis of embodiment one, in order to avoid the wires from being bent during wiring and affecting the conduction effect after wiring, the surface body 1 and the end cover 2 are improved: at this time, the surface body 1 is provided with a support assembly 5 corresponding to the position of the wire hole 201, and when the end cover 2 is assembled with the surface body 1, the support assembly 5 can be inserted into the wire hole 201 and provide a support effect for the wires.

[0046] To avoid affecting the assembly between the end cap 2 and the watch body 1 after the support component 5 is installed, a ramp 203 is provided at the bottom of the end cap 2. When the end cap 2 moves towards the watch body 1 for assembly, the ramp 203 can contact the support component 5 and drive the support component 5 to retract into the watch body 1. After the ramp 203 passes the support component 5, the support component 5 can automatically extend out from the watch body 1 to support the wire.

[0047] Reference Figures 6 to 8 In this embodiment, preferably, the support component 5 includes a support block 501 slidably mounted on the watch body 1. A second spring 502 is fixedly mounted between the support block 501 and the watch body 1, and the second spring 502 causes the support block 501 to tend to extend out of the watch body 1. Furthermore, a slope 503 is provided on the side of the support block 501 away from the second spring 502. The slope direction of the slope 503 is designed to be opposite to the slope direction of the ramp 203. When the ramp 203 contacts the support block 501, it can push the support block 501 to retract into the watch body 1. Subsequently, when the end cap 2 is removed from the watch body 1, the slope 503 can contact the end cap 2 and drive the support block 501 to retract into the watch body 1 again.

[0048] Correspondingly, a mounting groove 102 is provided at the bottom of the body 1 and at the step 101. The mounting groove 102 is used to mount the second spring 502 and the support block 501. The mounting groove 102 is close to the top of the step 101. The sliding direction of the support block 501 is parallel to the arrangement direction of the wire in the wire hole 201 based on the mounting groove 102, and they are in an upper and lower corresponding relationship, so as to achieve effective support for the wire.

[0049] It is understood that in this embodiment and in Embodiment 1, the following is used: Figure 1 From the perspective of the watch body 1, the end cap 2 can only slide back and forth and cannot be offset up and down. Moreover, the vertical dimension of the support block 501 extending from the watch body 1 is smaller than the vertical dimension of the thread hole 201. This allows the ramp 203 to stably contact the support block 501 during assembly of the end cap 2. In other words, after the end cap 2 is assembled with the watch body 1, the support block 501 is inserted into the thread hole 201, and the bottom of the support block 501 is not flush with the bottom of the end cap 2.

[0050] In use, through the end cover 2, the contact block 301 and the rotating seat 401 and other structures, the synchronous and rapid limiting of multiple electric wires can be realized, and it is also convenient for subsequent maintenance or replacement of a single electric wire. The working process and effect are the same as those in Embodiment One, and are not repeated here. The difference lies in that: after the multiple electric wires are placed in the threading hole 201 in sequence, the assembly of the end cover 2 to the surface body 1 can make the slope 203 first contact the supporting block 501, and make the supporting block 501 shrink into the surface body 1, and then the slope 203 continues to descend beyond the supporting block 501, and the supporting block 501 is automatically extended and reset under the action of the second spring 502; then the electric wire cannot descend in contact with the surface body 1 and the supporting block 501, and the contact block 301, the sliding rod 303, the flexible rack 302 and the gear 405 can drive the pressing cylinder 402 to descend, and after the pressing cylinder 402 descends, the effective limiting of the electric wire can be realized. At this time, the supporting block 501 is located in the threading hole 201, and the contact block 301 limits the electric wire in the middle. Subsequently, when the end cover 2 moves forward and is disassembled based on the surface body 1, the inclined surface 503 can contact the end cover 2 again to make the supporting block 501 shrink into the surface body 1, so as not to affect the rapid disassembly of the end cover 2.

[0051] Compared with Embodiment One, through the cooperation of the supporting block 501, the inclined surface 503, the slope 203 and the second spring 502, the supporting block 501 inserted into the threading hole 201 cooperates with the contact block 301 to limit the electric wire in the middle, which can avoid the bending deformation of the end cover 2 when it moves with the electric wire and contacts the stepped portion 101, and can also avoid the deviation after the stepped portion 101 to affect the wiring quality, thereby ensuring the reliable and stable conduction effect of the wiring quality of the electric wire. The overall scheme is combined with the setting of the surface body 1, which does not affect the rapid disassembly between the end cover 2 and the surface body 1, and the supporting block 501 does not need to be operated when the end cover 2 is disassembled, which can ensure a low labor burden.

[0052] Embodiment Three:

[0053] Please refer to Figures 1 to 10 On the basis of Embodiment Two, in order to improve the limiting effect of the electric wire, the rotating seat 401 is improved: at this time, the rotating seat 401 includes a vertical rod 4011 rotatably installed on the end cover 2 and an inclined rod 4012 rotatably cooperating with the vertical rod 4011, the vertical rod 4011 and the inclined rod 4012 are rotatably connected through a universal shaft, and the two can form a stable transmission state; the gear 405 is fixedly installed on the outer surface of the vertical rod 4011, the cross slot is opened on the surface of the vertical rod 4011 away from the inclined rod 4012, and the arc-shaped slot 403 is opened on the outer surface of the inclined rod 4012.

[0054] At the same time, the pressing cylinder 402 is sleeved on the outer surface of the inclined rod 4012, and in this embodiment, the telescopic rod 406 is designed to be inclined, so that the telescopic rod 406 can be in contact with the inclined rod 4012 when the pressing cylinder 402 is in the lowest position, and the telescopic rod 406 is in contact with the inclined rod 4012 when the pressing cylinder 402 is in the highest position. Figure 9From the perspective of the angle, the tilt direction is downward and pointing towards the body 1. The tilt design of the telescopic rod 406 allows the pressure cylinder 402 and the inclined rod 4012 to form a tilted state.

[0055] Furthermore, the bottom of the tilted pressure cylinder 402 is designed to be horizontal, so that when the pressure cylinder 402 moves along the tilted telescopic rod 406, its bottom can simultaneously make contact with the wire.

[0056] In use, the end cap 2, contact block 301 and rotating seat 401 and other structures can realize the synchronous and rapid positioning of multiple wires, which also facilitates the subsequent inspection or replacement of individual wires; through the support block 501, inclined surface 503 and second spring 502 and other structures, the support block 501 can cooperate with the contact block 301 to limit the wire in the middle, avoiding bending deformation and displacement of the wire. The working process and effect of this part are the same as in embodiment 2, and will not be repeated here. The difference lies in the following: when the wire stops descending after contacting the watch body 1 and the support block 501, the continued descent of the end cover 2 will cause the slide bar 303 to rise and move along the cavity 202 with the flexible rack 302. The flexible rack 302 drives the vertical rod 4011 to rotate through the gear 405. The vertical rod 4011 drives the inclined rod 4012 to rotate through the universal joint. The inclined rod 4012 drives the pressure cylinder 402 to move tilted based on the telescopic rod 406 through the arc groove 403 and the guide post 404. At this time, the pressure cylinder 402 not only has the function of pressing the wire, but also has the tilting pushing force, which can push the wire to have a tendency to move into the watch body 1.

[0057] Compared to Embodiment 2, through the cooperation of structures such as the vertical rod 4011, the diagonal rod 4012, the universal joint, and the telescopic rod 406, the pressure cylinder 402 can not only press the wire when moving, but also push the wire into the meter body 1. This improves the limiting effect on the wire and prevents the wire from falling out of the meter body 1, ensuring a long-term stable conductivity. The overall solution, combined with the rotating seat 401, maintains the same operation method for limiting and releasing the wire, but provides a better limiting effect on the wire and does not affect the quick assembly and disassembly between the end cover 2 and the meter body 1.
