Description

Technical Field

[0001] The utility model relates to the technical field of electric meters, in particular to a three-phase electric meter which is convenient for fixing a wiring harness. Background Art

[0002] A three-phase meter is an electrical instrument that is mainly used to measure electrical energy, so it is also called an watt-hour meter, a fire meter, an energy meter, or a kilowatt-hour meter. The structure of a three-phase meter includes a measuring mechanism, a compensation adjustment device, and auxiliary components. Compared with a single-phase meter, the main difference of a three-phase meter is that its multiple components share a rotating shaft and there is electromagnetic interference between the components.

[0003] During the installation and use of traditional three-phase electricity meters, wiring operations are required, and it is inevitable that a wiring harness will enter and exit the three-phase electricity meter. Since the wiring harness usually contains multiple wires, after entering and exiting the three-phase electricity meter box, the wiring harness will be randomly threaded in the box. If there are no proper fixing measures, these wires may be messy, which not only affects the appearance, but also may cause safety hazards, such as wire wear and short circuit. In view of this, we propose a three-phase electricity meter that is easy to fix the wiring harness. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] This embodiment provides a technical solution:

[0030] See also Figure 1-Figure 6A three-phase electric meter for fixing a wiring harness comprises an electric meter body 1; the electric meter body 1 comprises a box body 10, and a fixing part 2 for fixing the wiring harness is installed below the open rear side wall of the box body 10; the fixing part 2 comprises a connecting seat 20 fixed to the open rear side wall of the box body 10, a cavity 201 is opened at the center of the connecting seat 20, and sliding cavities 202 are opened on both sides of the cavity 201; two auxiliary bevel gears 22 are rotatably installed in the cavity 201, and a main bevel gear 21 is meshed on one side between the two auxiliary bevel gears 22; screw rods 24 are coaxially keyed on the auxiliary bevel gears 22, and the screw rods 24 penetrate into the sliding cavity 202; a slider 27 is slidably installed in the sliding cavity 202, and the slider 27 and the screw rod 24 threaded connection; a connecting plate 26 is installed at the end of the slider 27, and a second clamping block 28 is installed on one side wall of the connecting plate 26 at one side of the slider 27, and a second clamping groove 282 is opened on the second clamping block 28, and a connecting rod 283 slidably connected to the connecting plate 26 is fixed to the side wall of the second clamping block 28 close to the connecting plate 26, and a spring 29 is sleeved on the connecting rod 283, and the two ends of the spring 29 are respectively pressed against the second clamping block 28 and the connecting plate 26; two symmetrical first clamping blocks 25 are also fixed to the front end surface of the connecting seat 20, and the first clamping blocks 25 are fixedly connected to the connecting seat 20 by bolts, and the two end surfaces of the two first clamping blocks 25 that are away from each other are each provided with a first clamping groove 251.

[0031] Furthermore, a limiting block 284 is coaxially fixed at the end of the connecting rod 283, and the diameter of the limiting block 284 is larger than the diameter of the connecting rod 283. The setting of the limiting block 284 can prevent the connecting rod 283 from being separated from the connecting plate 26, thereby ensuring the stability of the second clamping block 28.

[0032] Furthermore, the overall shapes of the first clamping groove 251 and the second clamping groove 282 are both arc-shaped, and the first clamping groove 251 and the second clamping groove 282 are located on the same vertical plane. This design facilitates clamping and fixing the wire harness through the first clamping groove 251 and the second clamping groove 282.

[0033] Furthermore, an adjusting screw 23 is rotatably mounted on the front side of the connecting seat 20, and a connecting shaft is coaxially keyed between the adjusting screw 23 and the main bevel gear 21. This design facilitates driving the main bevel gear 21 to rotate through the adjusting screw 23, and has the advantage of easy operation.

[0034] Furthermore, two end surfaces of the two first clamping blocks 25 that are separated from each other are provided with two slots 252, and two plug boards 281 are fixed to one end surface of the second clamping block 28 that is close to the first clamping block 25, and the plug boards 281 are plugged and matched with the corresponding slots 252. Through the matching of the plug boards 281 and the slots 252, the tightness of the connection between the first clamping block 25 and the second clamping block 28 can be improved, and the wiring harness can be prevented from escaping from the gap between the first clamping block 25 and the second clamping block 28.

[0035] Furthermore, the front and rear walls of the slide cavity 202 are both fixed with guide rails 203, and the front and rear walls of the slider 27 are both provided with slide grooves 271 slidably connected to the guide rails 203. The arrangement of the guide rails 203 and the slide grooves 271 ensures that the slider 27 moves stably and smoothly.

[0036] Furthermore, the second clamp block 28, the plug plate 281 and the connecting rod 283 are an integrally formed structure, and the second clamp block 28, the plug plate 281 and the connecting rod 283 are all made of plastic. The integrally formed structure has better connection strength, and the plastic material has the advantage of insulation, which improves the safety of the second clamp block 28.

[0037] Further, a reversible door 11 is provided on the front side of the box body 10, and the door 11 is hinged to the box body 10 through a hinge. The door 11 can be provided to prevent dust and protect the components in the box body 10.

[0038] It can be understood that the bottom of the box 10 in this embodiment is provided with two symmetrical through holes for threading. The through holes are arranged to facilitate threading, and the through holes are located below the first clamping groove 251. This design facilitates the wiring harness to pass through the through holes and be fixed at the first clamping groove 251.

[0039] It should be added that one end face of the second clamp block 28 in this embodiment fits against the outer wall of the connecting seat 20. This design can prevent the second clamp block 28 from rotating, thereby facilitating the second clamp block 28 to cooperate with the first clamp block 25 to better clamp and fix the wiring harness.

[0040] During specific use, the user first passes the wiring harness through the first clamping groove 251, and then the user rotates the adjusting screw 23. The adjusting screw 23 drives the main bevel gear 21 to rotate. Since the main bevel gear 21 is meshed with the secondary bevel gears 22 on both sides, the secondary bevel gears 22 rotate and drive the screw rod 24 to rotate. As the screw rod 24 rotates, the sliders 27 on both sides slide along the sliding cavity 202. The sliders 27 simultaneously drive the connecting plate 26 and the second clamping block 28 to move. The second clamping block 28 simultaneously drives the first clamping block 25 to approach one side, and the plug plate 281 is simultaneously aligned with the slot 252 and inserted. When the first clamping block 25 is pressed against the second clamping block 28, the spring 29 is compressed. At this time, the wiring harness is clamped and fixed by the first clamping block 25 and the second clamping block 28.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
