Abstract

The utility model provides a quick wire connector, which is suitable for connecting conductive wires quickly in the line with small or middle power. The utility model is composed of clamping sheets with clamping grooves, a casing, and a base, wherein, a relative displacement is arranged among the clamping sheets, the casing and the base. The utility model solves the problem that the wiring operation of the screw clamping connecting terminal is complex. When the wires are connected, the insulating layers of wires do not need peeling off, the wire ends are directly inserted into wire connecting holes of the wire connector, and the connection can be finished by disposable simple motion such as the press or the rotary press. The operation is convenient and quick, and the operation can be done with the power. The volume of the utility model is the same with the size of fingers, and the utility model can be used in various electromechanical devices, household appliances, distribution circuits, and lighting circuits.

Description

Quick connector

The utility model relate to a kind of in, the binding post used in electric line of small-power.

Binding post generally adopts screw crimping mode to realize conducting at present.Must be earlier when being wiring will wait that the insulating barrier that connects wire termination pulls out, the heart yearn that will expose is wrapped on screw or the double-screw bolt again, or inserts wiring hole, screws screw or nut then and pushes down heart yearn and form joint and realize conducting.Can find out that thus the operational sequence of this mode is more loaded down with trivial details, and be difficult for hot line job.Sometimes, operator's technical merit also may influence the work quality of joint.

The purpose of this utility model is to utilize a kind of novel clamping technical scheme, is guaranteeing to realize fast-wiring and hot line job under the reliable prerequisite that connects.

The involved clamping technical scheme of the utility model is by the clamping sheet with can drive a kind of lead clamping apparatus that housing that lead snaps in the clamping sheet, base etc. constitute and realize by a kind of.We are referred to as fast-wiring (hereinafter to be referred as connecing son soon) to this device.

Lead clamping principle as shown in Figure 1.During wiring, need not to pull out wire insulation, only need lead is cut the insulating barrier 3 of lead when lead snaps in from two cutting edges 5 that notch 4 is pressed into draw-in groove inner card cage mouth place, lead core 2 comes in contact with draw-in groove both sides sword, simultaneously, clamp-on draw-in groove because of core clamping sheet generation bullet is become, play the living elastic force pressure of the sell of one's property and make draw-in groove limit sword extruding core form reliable clamping and conducting.

This connects sub most important parts soon is clamping sheets, and it is made with elastic conducting material.This clamping sheet can be made into different shape according to different purposes.As, straight sheet, bent angle shape, L type, U type and tubular or the like.Regardless of they shapes, its common ground is all to have the draw-in groove that the card line is used on the clamping sheet.But draw-in groove straight line or curve can be split into single groove or multiple-grooved on the clamping sheet.

For realizing the card press operation, another key character of the technical program is the clamping housing.Except that adopting simple tools that lead is snapped in the clamp groove form, realize fast-wiring and live line working, also can design a kind of structure that lead can be pressed into draw-in groove.This programme is realized by the clamping housing.This housing is made by insulating material, which is provided with the line hole, and housing drives lead and clamping sheet generation relative displacement under external force, thereby lead is pressed in the draw-in groove.In addition, also have the detection hole that voltage test pencil can be inserted on the housing,, also louvre can be set in case of necessity so that detect and maintenance.

Base is used for installing clamping sheet and clamping housing.Sometimes base needn't be made separately, can utilize the pedestal on the electrical equipment to constitute.Be provided with the conductive plate that is connected with electrical equipment or other circuit in the base, by thread connecting mode or welding manner and the conducting of clamping sheet.The base operated by rotary motion grooved hole of making so that clamping sheet and housing are installed, and guarantees reliable clamping separately.

This son that connects soon that the utility model relates to, its maximum characteristics are to realize the quick connection and the live line working of lead, and wiring quality is reliable.Use this to connect son soon, lead need not be pulled out insulating barrier, only needs directly lead to be inserted line-entering hole.By pushing or easy operation such as spinning, the draw-in groove that just lead can be snapped on the clamping sheet is realized conducting.And, be not to block in whole garden week owing to snap in the wire insulation of draw-in groove, rely on the elasticity of incision insulating barrier, also can play sealing function to card contact.Prevent cavitation erosion, improve wiring quality.

The utility model relates to connects son soon, and the occasion difference with using has multiple version.

Shown in Figure 2 is a kind of rotary clamp type fast-wiring.Tubular clamping sheet 10 usefulness screws 13 are fixed on the base 6, and are communicated with conductive plate 15, this conductive plate can with other electric appliance circuits UNICOM.Clamping housing 9 can relatively rotate with tubular clamping sheet 10.During wiring, directly lead is inserted line-entering hole 12, screwdriver is inserted in the spin slot 8, turn housing 9 drives lead and snaps in the draw-in groove 11 that distributes in tubular clamping sheet upper edge horizontal garden week, thereby realizes conducting.By detecting hole 7, can detect.Clamping housing rotating angle θ is located with the groove on the base by its lower edge locating convex block 14 to control.If will remove lead, only need reverse turn, lead can withdraw from draw-in groove.

Shown in Figure 3 is a kind of direct clamping type fast-wiring.Lead is inserted line-entering hole 17, push gland 16 with thumb or other instrument, gland drives lead and enters draw-in groove 18 and the conducting of clamping sheet, and guarantees reliably to be connected with the buckle 21 on gland both sides by base 19.

Shown in Figure 4 is straight card-U type fast-wiring.It is mainly used in being connected of single line and single line.Two leads are placed two end line hole seats 25 of connector respectively, the gland 22 that closes, the U type clamping sheet 24 on the gland blocks lead under external force and realizes two line conductings.And, guarantee reliably to connect by buckle 26 fastenings.

Shown in Figure 5 is a kind of threeway connector.It is mainly used in the conducting between single line and two lines, i.e. threeway.Line hole one end on this connector base 32 is single line hole 29, and the other end is two-wire hole 31, three leads are inserted the homologous lines hole respectively after, the gland 28 that closes, the clamping sheet 27 on the gland block under external force realizes three-way conducting.And, guarantee reliably to connect by buckle 30 fastening glands.

Several connect son soon and are used in combination with corresponding base, can form various wiring circuit, also can be made into special wiring terminal plate or junction box.Shown in Figure 6 is a kind of rotary clamp type junction box.Six revolve card and connect son 34 soon each other by the conductive plate UNICOM in the base 35, and Fig. 7 is the circuit diagram of this junction box.Transparent cover 33 can play protection and connect son soon, increases the effect of visual and aesthetic property.
