Abstract

The utility model relates to a wire joint technology, particularly to an occlusion type wire joint for solving problems that multi-strand core wires are not wholly contained due to a linear opening provided on the wiring pipe end of a stud gasket type connector lug and that an enclosed gasket cannot be installed onto an enclosed binding post in the prior art. The occlusion type wire joint comprises a wiring pipe and a pad portion integrally connected with the wiring pipe and is characterized in that the butt-joint mouth portion of the wiring pipe is provided with a curve occlusion wire and the pad portion is provided with a cutting notch. With the occlusion type wire joint, a single strand thin core is completely prevented from being exposed during the wiring of multi-core wire ends, higher compaction is enabled, direct insertion of a binding post can be enabled by taking advantage of the pad cutting notch, and wiring installation on some special occasions may be satisfied.

Description

The biting connecions power lug

Technical field

The utility model relates to the power lug technology, especially a kind of biting connecions power lug.

Background technology

Power lug is requisite wire connector in the modern mechanical electric equipment products, and the version of power lug is also varied, and its characteristics of each tool.Number being a kind of power lug of CN101350457Y as patent announcement, being divided into and two kinds of " one " form and "T"-shaped formulas, be respectively applied to two lines and connect and be connected with three lines, is tubulose or threeway shape structure.Be the disclosed a kind of power lug structure of CN102496788A as patent publication No., comprise the binding post of being located in the electric wire box, binding post is provided with the wire hole that traverses binding post, also be provided with on the binding post for the fastener hole that electric wire is fastening, the axis of fastener hole and the axis normal of wire hole, electric wire inserts in the fastener hole fastening by securing member, the fastener hole middle part is to outer lug, form the drum type structure, fastener hole is connected with wire hole, and the shape of securing member and the shape of fastener hole are complementary.This structure adopts the mode of pressing, and the securing member of drum type is pressed entered the fastener hole connection; Be applicable to electric wire connection more in short-term.Patent announcement number is CN201898210U for another example, a kind of two wire linear pattern wire connecting joints that are applicable to, and joint geometry is that cross section is the hollow metal column of arc, outer surface and the edge of column are provided with insulating barrier; Disclose a kind of wire that is applicable in addition and be overlapped on the power lug on another wire, its shape totally is the T type, its middle transverse part shape structure is consistent with aforementioned electric wire terminal shape structure, the vertical part columnar metal body that to be an end fixedly be electrically connected with transverse part, the outer surface of an end that joins with transverse part on the vertical part is provided with insulating barrier.The connected mode of the inapplicable double-screw bolt packing ring of these structures shape.The opening of its wiring pipe end of double-screw bolt packing ring shape of the prior art is straight line, and the end of a thread easily exposes, and packing ring partly is sealing ring, and when the two ends of wiring screw rod all are connected with other part can't dismantle the time, this sealing ring is adorned to be entered.

Summary of the invention

The purpose of this utility model is to cause the multiply heart yearn to be difficult to full containing for the wiring pipe end straight line opening that solves double-screw bolt grommet-type connector lug in the prior art, and sealing gasket can't be installed on the problem on the closed binding post, a kind of reasonable in design is provided, wiring pipe end inclusion line adopts curve, can contain the multiply core entirely, is provided with the biting connecions power lug of dislocation open washer structure.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of biting connecions power lug, comprise the pad portion that wire barrel and wire barrel are connected as a single entity, it is characterized in that described wire barrel docking port position is provided with the curve lines of occlusion; Described pad portion is provided with disconnected otch.Curl internal diameter that the back forms of wire barrel position is generally slightly little than required wire connecting wire core diameter, thoroughly compress core to help, but the deviation during owing to material error or curling wiring pipeline section, core often can not contain fully, especially the electric wire of multiply core, the defective of straight line opening, i.e. parallel breach have been avoided in the design of curve such as S shape lines of occlusion, it is alternately also interlock mutually, and the thin core of sub-thread can not exposed from parallel breach.The disconnected otch of pad portion adopts same annular ring to reach the standard grade and cuts, and can utilize disconnected otch that binding post is inserted in the pad centre bore, just replys the packing ring original state after compressing, and also can be used as plain washer and uses.

As preferably, described curve lines of occlusion axially arranges along wire barrel.When making wire barrel, washer portion and wire barrel are disposable stamping forming, and the center line of curve lines of occlusion is just parallel towards the diameter of wire barrel direction with the washer portion centre bore.

As preferably, the two ends that described pad portion is cut apart by the otch that breaks are along the centre bore axis direction dislocation of pad portion.Disconnected otch after the dislocation can be Binding post/stud along the breach plug-in mounting, and this mode especially is fit to the Binding post/stud two ends and can't uses during the suit packing ring.Disconnected otch after the dislocation also has certain elasticity, is conducive to compress as spring washer.

The beneficial effects of the utility model are: the thin core of sub-thread exposes when having avoided the wiring of multiple core cord termination fully, and compaction degree is higher, utilizes pad to cut off directly plug-in mounting binding post of mouth, satisfies the wiring in some special places simultaneously and installs.

Fig. 2 is a kind of confined state structural representation of the present utility model.

Among the figure: 1. joint, 11. curves, 12. disconnected otch, 13. pad portions, 2. clamp nut, 3. plain washer, 4. Binding post/stud.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

Referring to Fig. 1, a kind of biting connecions power lug of present embodiment, formed by wire barrel and pad portion 13 two parts, pad portion 13 and wire barrel add the disposal molding in man-hour, the docking port position of wire barrel is sigmoid curve lines of occlusion 11, and the center line of curve lines of occlusion 11 is parallel with the diameter of pad portion 13 centre bore forward wire barrel center lines.Open an oblique fracture otch 12 at the annular solid of pad portion 13, namely break otch 12 and the inclined to one side angle of pad portion 13 center-hole diameters are as miter angle.The direction of disconnected otch 12 can be divided by the branch of i.e. left-handed, the dextrorotation of the thread rotary orientation on the Binding post/stud 4, can play the retaining effect.

When peeling back, electric wire end was connected with the wire barrel position, because curve lines of occlusion 11 is on same straight line, its breach also was curve, and when compressing for multi-core cable, the sub-thread heart yearn has just been avoided from breach ejection fully or exposed.

During use, as shown in Figure 2, pad portion 13 can be used as the existing conventional shim form and installs, and namely is inserted in from Binding post/stud 4 ends.Another kind of assembling mode is utilized the disconnected otch 12 of pad portion 13, directly is inserted into from the side on the Binding post/stud 4, and recycling clamp nut 2, plain washer 3 compress.The pad portion 13 of this device has elasticity, helps to compress retaining.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any structure after the simple transformation of the present utility model is all belonged to protection range of the present utility model.
