Abstract

The utility model relates to a wedge connecting terminator, which belongs to the electric contact interconnection technique of electric field. The wedge connecting terminator is provided with a piece of external thread; a taper hole is arranged in the middle of the wedge connecting terminator from ends along axial direction; a hollow cone wedge sleeve is arranged in the taper hole; the wall portion of the taper hole is provided with a through slot whose both ends, an inner circle surface and an outer circle surface are open; the outside of the through slot is provided with a lock nut; the middle part of the end surface of the lock nut is provided with a ladder-shaped through hole; internal threads are arranged in the through hole. Compared with the existing techniques, the utility model has the advantage of convenient operation; a circular conducting wire is wrapped and connected tightly by a connection end under the action of the wedge of two times; the electric conduction contact electricity is firm fully; the utility model still has energy saving property, safety and consumable material saving, and the terminal of a whole wire connection end is cabinet.

Description

Cover of wedge formula terminals

The utility model is a kind of terminals that are used to connect garden shape lead, belongs to the electric contact interconnection technique of electric field.

Mainly contain with the prior art that the utlity model has comparativity:

1, bolt clip is board-like, goes up connection garden shape lead one end as " screw bolt-type device clamp " (drawing certainly, " power engineering design manual " Shanghai science tech publishing house publishes), and this technology connects garden shape lead by the clamping action of some groups of bolts and clamping plate.

2, compression joint type, as an end of the last connection garden of " crimp type device clamp " (quoting as proof the same) shape lead, this technology is by compression tools or equipment the tubulose terminals to be oppressed the effect of its Internal Hole Deformation is connected garden shape lead.

3, welded type, this technology are the replacements of compression joint type, promptly adopt the mode of welding that the tubulose terminals are connected with garden shape lead solid welding by soldering appliance or equipment.

The deficiency of above-mentioned these three kinds of technology is: use operation trouble relatively; Conductive contact surfaces is relatively little; The volume increase that then can make terminals for the conduction contact is met the requirements, consumptive material increases; The easy virtual connection of troublesome poeration, and conductive contact surfaces is little all can cause contact heating power consumption even sintering briquette, so also relative mistake of energy saving and fail safe.

The utility model aims to provide a kind of easy to operate simple and direct, conductive contact surfaces is abundant, it is firm to connect, volume is relatively little, consumptive material is economized relatively, the terminals that are used to connect garden shape lead that the energy saving fail safe improves relatively, this terminals can be in conjunction with the various electrical connectors of manufacturing or in conjunction with being manufactured on the various electric equipments.

Implementation of the present utility model is as follows:

It has one can with various electrical connectors or electric equipment terminals body built in one, this terminals body has one section external screw thread, from end face a bellmouth is arranged vertically; Be provided with a cover of wedge in it, described cover of wedge, body shape is truncate hollow cone, and a big end wall end face is arranged, Qi Bibu has a groove of opening two ends and inner and outer circumferential surfaces; A locking nut arranged in that terminals are external, it is a step shape through hole in the middle of axially, has in the big relatively hole of through hole step face to make internal thread.Wherein the hollow cone tapering of cover of wedge is consistent with the bellmouth tapering of terminals body; The external screw thread of terminals body and the screw thread of locking nut are complementary.

Because the whole operation process is except threading, have only a process that one group of screw thread subplate is twisted, and tool using need only common wrench, therefore operation is very convenient simple and direct; Because cover of wedge is consistent with the bellmouth tapering of terminals body, because cover of wedge packs tightly to the axle center the termination integral body that is connected of garden shape lead, have very strong interference stress owing to the secondary wedge effect that comprises screw thread pair makes joint face, so conductive contact surfaces is abundant and firm; Because conductive contact surfaces fully firm, whole terminals volume just can design small and exquisitely, and consumptive material is saved relatively, and energy saving, fail safe also improve relatively; Because the structure and the function of these terminals only are embodied in " end " portion, therefore can be under this total design with these terminals in conjunction with being designed and manufactured into various electrical connectors or combination manufactures and designs on various electric equipments.

For making the utility model have more integrity, the groove of its cover of wedge can be axial setting, also can be the rotation direction setting, promptly left-handed or dextrorotation, this be for the strand of the twisted wire that when connecting garden shape twisted wire, as far as possible staggers to, avoid in certain strand of single line embedded groove and the wedging that influences cover of wedge packs tightly; The big end wall end face of its cover of wedge can be made into the sagittal plane, also can be made into its suitable conical surface of the conical surface, and this is to be subjected to the wedging force direction more reasonable for what make cover of wedge; The through hole step face of its locking nut also can be made into the form of the big end wall end face of cover of wedge and makes the sagittal plane or the conical surface.

The material that the utility model adopted can be the various conductor materials that adapt.

Below in conjunction with accompanying drawing structure of the present utility model and feature are offered some clarification on:

Fig. 1 is the axial cutaway view after the complete combination of the utility model; The double dot dash line frame table on dual slope the right shows can be in conjunction with other position or the electric equipment main body that manufacture and design at the various electrical connectors of one.

Fig. 2, Fig. 3 represent the groove of cover of wedge and the form that big end wall end face can be made into.

Fig. 4 represents the form that the through hole step face of locking nut can be made into.

Expression feature subject name of the present utility model and mark should be mutually among Fig. 1, Fig. 2, Fig. 3, Fig. 4: terminals body (1), cover of wedge (2), locking nut (3), the external screw thread of terminals body (4), the bellmouth of terminals body (5), the groove of cover of wedge (6), the big end wall end face (7) of cover of wedge, the internal thread of locking nut (8), the through hole step face (9) of locking nut.

One with various electrical connectors or electric equipment terminals body (1) built in one, be provided with one section external screw thread (4), be provided with a bellmouth (5) vertically from end face, be provided with a cover of wedge in it, body shape is truncate hollow cone, a big end wall end face (7) is arranged, and Qi Bibu has a groove (6) of opening two ends and inner and outer circumferential surfaces, and big end wall end face can be made into the conical surface; External a locking nut is arranged at terminals, it is step shape through hole in the middle of axially, and a through hole step face is arranged, and can be made into the corresponding conical surface, makes internal thread (8) in the opposed hole.

It is to realize like this to the linkage function of garden shape lead, after shape lead termination, connected garden penetrates in the cover of wedge by locking nut again, along with constantly being screwed into of locking nut, the through hole step face of locking nut is just oppressed the big end wall end face of cover of wedge, make the bellmouth of cover of wedge wedging terminals body, periphery is limited by the bellmouth of terminals body because cover of wedge wall portion has groove, being continued to oppress the cover of wedge of wedging in the bellmouth of terminals body can only wholely shrink to the axle center, thereby garden shape lead interference is packed tightly.
