Abstract
The utility model discloses a terminal that is simple in structure, low in cost, stable in wire connection and high in safety performance and capable of realizing quick dismounting. The quick dismounting terminal includes a joint body (1) and a fastening piece in screw-thread fit with the joint body (1). The joint body (1) is composed of a wiring terminal (11), a connection segment (12), a threaded segment (13) and a wire clamping part (14). The wire clamping part (14) is composed of a plurality clamping pieces (141) arranged in an encircling manner and is cone-shaped. The fastening piece (2) is inside provided with a female-threaded segment (21) fitting with the threaded segment (13) and a conical segment (22) fitting with the wire clamping part (14). The inner diameter of the conical segment (22) is smaller than the inner diameter of the wire clamping part (14). The quick dismounting terminal can be applied to the field of power equipment.
Description
Technical field
The utility model relates to a kind of binding post, relates in particular to a kind of terminal that can fast assembling-disassembling.
Background technology
Need to use a large amount of binding posts at power domain.At present, the binding post that power domain uses is generally at one end of one section of hollow circuit cylinder a connection end b, perforate c on termination, as depicted in figs. 1 and 2; Cylinder a and termination b are one-body molded.In the time that overhead wire is installed, termination one terminated line, then inserts another wiring in cylinder, then with hydraulic test, cylinder is pressed from both sides flat, by making cylindrical end be out of shape to clamp wiring.This binding post can only disposablely use, and cannot realize displacement.As Fig. 3 shows external a kind of binding post, this kind of binding post comprises cylinder a and termination b equally, it arranges a screwed hole on the wall of cylinder a, by coordinate a bolt d in screwed hole, insert after cylindrical inside in wiring, bolt d is screwed, compress wiring by bolt d, thereby realize the connection of wiring.But this connection terminal structure complexity, manufacturing cost is higher.In addition, due to the pulling force of wiring, in use, its screw thread joint portion there will be skidding to bolt after exposing to the sun and rain for a long time, occurs the dangerous situation that wiring comes off.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and cost is low, wiring is stable, safe and can realize the terminal of fast assembling-disassembling.
The technical scheme that the utility model adopts is: the utility model comprises joint body and the securing member with described joint body threaded engagement, described joint body is made up of terminal stud, linkage section, thread segment and crimping, described crimping by some intermediate plates around forming and described crimping is cone-shaped, described securing member inside is provided with the internal thread segment matching with described thread segment and the conical section matching with described crimping, and the internal diameter of described conical section is less than the internal diameter of described crimping.
In the outside wall surface of described securing member, be provided with nut six quadrate parts.
The number of described intermediate plate is four.
The beneficial effects of the utility model are: because the utility model comprises joint body and the securing member with described joint body threaded engagement, described joint body is by terminal stud, linkage section, thread segment and crimping composition, described crimping by some intermediate plates around forming and described crimping is cone-shaped, described securing member inside is provided with the internal thread segment matching with described thread segment and the conical section matching with described crimping, the internal diameter of described conical section is less than the internal diameter of described crimping, so, the utility model is in the time installing wiring, only wire need to be passed to described securing member and inserts in described crimping, then described securing member and described thread segment are screwed, utilize the internal diameter of conical section of described securing member less than the internal diameter of described crimping, in securing member precession process, crimping is caused compressing and stably fixes wire, safe and can realize fast wiring dismounting, in addition, the utility model is simple in structure, and cost of manufacture is low, can reduce widely the production cost of enterprise, and reusable, economize on resources, and its electric conductivity excellence, temperature rise is low, and long service life has good energy-saving effect.

Embodiment
As shown in Fig. 4 to Fig. 5, the utility model comprises joint body 1 and the securing member 2 with described joint body 1 threaded engagement, described joint body 1 is made up of terminal stud 11, linkage section 12, thread segment 13 and crimping 14, described crimping 14 by some intermediate plates 141 around forming and described crimping 14 is cone-shaped.In the present embodiment, the number of described intermediate plate 141 is four.Described securing member 2 inside are provided with the internal thread segment 21 matching with described thread segment 13 and the conical section 22 matching with described crimping 14, and the internal diameter of described conical section 22 is less than the internal diameter of described crimping 14.In the outside wall surface of described securing member 2, be provided with nut six quadrate parts 23.
The utility model in use, arranges different crimpings and securing member internal diameter according to the model of wire.If not when gauge wire is installed, can install several little wires additional or be wound to the internal diameter that is slightly less than crimping with aluminium armor tape around wire.Before installing, wire is vertically sawed-off with hacksaw, ensure that cable port part is smooth not loose, then on wire, coat conductive paste, wire is inserted to described crimping, described securing member is screwed, complete installation of the present utility model.After installing, need to firmly twine wire incoming line and strengthen securing member with water-impervious with adhesive waterproof tape multilayer ground.
The utility model is applicable to power transformer, asynchronous or synchronous machine, voltage or current transformer, power capacitor, kilowatt meter measuring device, falling fuses, lightning rod, oil switch, air switch, circuit breaker contactor, power factor compensation cabinet, the connection of alternating current-direct current switchboard electric wire etc.It has that corrosion resistance is strong, surface contacted resistance is little, move the advantages such as temperature rise is low, electric energy loss is few, energy-saving effect is remarkable under nominal current conditions, can be repeatedly used, (having replaced loaded down with trivial details hydraulic test with spanner) easy to use, maintainability and highly versatile, the feature such as reliability is high, anti-ice calamity performance is strong, be the desirable regeneration product of DT, DL, DTL series binding post and STL copper-aluminium transition equipment cable clamp.
The utility model can be applicable to field of electrical equipment.
