Abstract
The utility model discloses a novel connection device for an electric power cable. The novel connection device comprises two pressing plates and a supporting plate, wherein an arc-shaped bent end part is arranged at the both ends of the supporting plate respectively; the pressing plates are rotary-type pressing plates, one end of one pressing plate is a rotary shaft, and the other end of the pressing plate is an arc-shaped groove; one end of the other rotary-type pressing plate is a rotary groove, the other end of the rotary-type pressing plate is an arc-shaped groove, the rotary shaft is sleeved in the rotary groove and capable of rotating, through holes are formed in the rotary shaft, the rotary groove and the supporting plate, and hold-down bolts are arranged by penetrating through the through holes; the through holes are strip-shaped groove holes; at least one through hole and at least one hold-down bolt are provided and mutually matched; and the curvature radius of the arc-shaped groove is equal to the curvature radius of the arc-shaped bent end part. The novel connection device is reasonable in design, simple in structure, firm in connection, and good in anti-zero-interrupt effect.
Description
Technical field
The utility model relates to the power supply technical field, especially relates to a kind of novel electric power cable connecting device.
Background technology
At present, in the supply line of China, the situation that a certain phase or two-phase equipment burn out in a large number takes place sometimes.When this thing happens, user's single-phase power load was connected mutually by zero line.Because the imbalance of each phase load makes phase voltage seriously unbalance, the light phase voltage of loading is the highest, and this phase power consumption equipment burns out earlier, and and then the power consumption equipment of other phases is also burnt because voltage raises.Disconnected zero danger that burns out equipment also is its disguise, though disconnected zero back in a period of time of beginning bulb still bright, motor still change, people are difficult in time find fault and are got rid of, and just find disconnected zero, late after the equipment for the treatment of burns in a large number.Cause disconnected zero factor a lot, wherein important reasons is exactly that the binding clip at zero line two ends occurs loosening, cause loose contact and burn binding post, the present normally used mode of connection is: line nose and binding post socket are made in the end of zero line, compress with nut again.The easy oxidation of this kind connected mode center line nose causes loosening heating, burns bolt and nut, and then blows zero line.
The utility model content
The purpose of this utility model is to provide a kind of novel electric power cable connecting device, and it is reasonable in design, simple in structure, be connected firmly, anti-breaking zero effective.
For achieving the above object, the technical solution of the utility model is:
The novel electric power cable connecting device comprises two pressing plates and a supporting plate, and described two ends of bearing plate arranges an arc-shaped bend end respectively; Described pressing plate is rotary pressing plate, and an end of one of them pressing plate is rotating shaft, and the other end is arc groove; One end of another rotary pressing plate is turn trough, and the other end also is arc groove, and described shaft set is in turn trough and can rotate, and is provided with through hole on described rotating shaft, turn trough and the supporting plate, runs through this through hole and is provided with hold-down bolt; Described through hole is bar shape trench hole; The quantity of described through hole and hold-down bolt is at least one and mutual coupling; The radius of curvature of described arc groove is consistent with the radius of curvature of described arc-shaped bend end.
The beneficial effects of the utility model are:
The utility model has changed traditional mode of connection and binding clip structure, makes two rotary pressing plates compress zero line and binding post respectively by hold-down bolt, improves contact reliability, reduces disconnected zero probability.The connected mode of rotation crimping is flexible, stretches out to both sides respectively under the effect of bolt, in order to compress zero line and binding post.The bar shape trench hole that the rotary pressing plate of the utility model is provided with is convenient to mutual rotation, and hold-down bolt can be compressed.The utility model is reasonable in design, simple in structure, be connected firmly, anti-breaking zero effective, it is applied widely, is not only applicable to being connected of zero line and binding post, also is applicable to interconnecting between two power lines, has good economy after the popularization and imitates.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, take a hint.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the electric power cable jockey contains fixed head 4, rotary shaft pressing plate 2 and turn trough formula pressing plate 5 in the present embodiment, fixed head 4 two ends arrange an arc-shaped bend end respectively, one end of rotary shaft pressing plate 2 is rotating shaft, and the other end is arc groove, and an end of turn trough formula pressing plate 5 is turn trough, the other end also is arc groove, shaft set is in turn trough and can rotate, and is provided with through hole on rotating shaft, turn trough and the fixed head 4, runs through this through hole and is provided with hold-down bolt 3.Through hole is bar shape trench hole, so as rotating shaft when in turn trough, rotating hold-down bolt 3 be not stuck.In addition, the quantity of through hole and hold-down bolt 3 is at least one and mutual coupling; The curvature diameter of the curvature diameter of arc groove and arc-shaped bend end is complementary, and is convenient to fix power line.
During use, unclamp hold-down bolt 3, zero line 1 and binding post 6 are inserted in respectively in the arc-shaped bend end of fixed head 4, screw hold-down bolt 3, make rotary shaft pressing plate 2 and turn trough formula pressing plate 5 to the both sides extruding, and then compress zero line 1 and binding post 6, zero line 1 and binding post 6 are well linked together, contact is good, good conductivity.
Other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
