Abstract
The utility model discloses a low-voltage lead wire device which comprises an insulator body (2) between two copper bars (1), wherein through holes are formed in the insulator body (2); insulation tubes (4) penetrating into the through holes (3) are respectively arranged at two ends of the through holes (3); the insulation tubes (4) and the through holes (3) are in tight fit; a screw bolt (5) penetrating the insulation tubes (4) and the through holes (3) is arranged in the insulation tubes (4); and gaskets (6) and nuts (7) are respectively arranged at the two ends of the screw bolt (5). The low-voltage lead wire device has the advantages of convenience in installation and firm structure, adopts a simplified assembly process, and has better insulator strength and improved assembly efficiency, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of dry-type transformer parts, particularly a kind of low-voltage lead device.
Background technology
At present, what the low-voltage lead insulated terminal of dry-type transformer adopted usually is the screw-type insulated terminal, and what such insulated terminal adopted is the internal thread that the two ends size specification differs; And the screw thread in the middle of the insulated terminal neither lead to screw thread, so; When assembling, because two ends all adopt bolt, nuts and washers to fix, if the insufficient strength of insulator; When tightening, crackle can appear in insulator, causes insulator to be scrapped; Increased manufacturing cost, and, assembled also comparatively loaded down with trivial details because the versatility of screw bolt and nut is not strong.
The utility model content
The purpose of the utility model just provides a kind of high strength, low-voltage lead device easy for installation.
The purpose of the utility model is to realize through such technical scheme; A kind of low-voltage lead device comprises the insulator body between two copper bars, in insulator body, is provided with through hole; Be respectively arranged with the insulated tube that penetrates through hole at the two ends of through hole; Said insulated tube and through hole adopted tight fit, in insulated tube, were provided with the screw rod that runs through insulated tube and through hole, were respectively arranged with packing ring and nut at the two ends of screw rod.
Owing to adopted technique scheme, the utlity model has advantage easy for installation, well-set, adopt it to simplify assembling process, make insulator strength better, improved efficiency of assembling, reduced manufacturing cost.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these execution modes; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1; A kind of low-voltage lead device comprises the insulator body 2 between two copper bars 1, in insulator body 2, is provided with through hole 3; Be respectively arranged with the insulated tube 4 that penetrates through hole 3 at the two ends of through hole 3; Said insulated tube 4 adopted tight fit with through hole 3, in insulated tube 4, was provided with the screw rod 5 that runs through insulated tube 4 and through hole 3, was respectively arranged with packing ring 6 and nut 7 at the two ends of screw rod 5.
In the utility model, with insulated tube 4, copper bar 1 and insulator body 2 orderly linking together, do as a wholely with screw rod, strengthened integral intensity greatly.Simultaneously, such structure also helps two corrections between the vertical copper bar.
