Description

A kind of modified form binding clip

Technical field

The utility model relates to a kind of modified form binding clip, is mainly used in the various circuit appliances of conducting.

Background technology

At present, it is very many that binding clip uses, but common binding clip is generally copper sheet or steel plate manufacturing, because the metallic copper price is high for a long time, binding clip is smaller, and manufacturing process is also uncomplicated, therefore to account for the ratio of total cost very big for material cost, and product is lacked competitiveness.Metallic copper is softer, so the clamping force of binding clip is restricted easy deformation in making and the use.If adopt the steel plate manufacturing, conduction property is too poor, and product does not have competitiveness yet.For example: Chinese patent 200720108345.4 utility models relate to a kind of storage battery folder, comprise left clamp and right clamping body, be coupling by bearing pin between left side clamp and the right clamping body, bearing pin is provided with back-moving spring, described left clamp internal fixation is connected with left clamping plate, and the right clamping body internal fixation is connected with right clamping plate, is fixedly connected with lead on the left clamping plate, the lead outer surface is smooth structure or outer surface is pattern structure, and the mating surface of described left clamping plate and right clamping plate is provided with laciniation.This binding clip be commercially available the same, be a kind of made.The cost height, otherwise conduction property is good inadequately.

Normally used binding clip jaw mostly is crocodile mouth structure or bolt structure, and when being used to connect stranded conductor, because the diameter of lead is very thin, meeting pinch off part metals lead is easy to heating and blows lead, brings inconvenience to the user.

The utility model content

The utility model mainly is to solve the existing in prior technology problem to be, binding clip intermediate plate function is not divided, or all is copper, or is steel all, and product is lacked competitiveness.

The utility model solves another problem of existing in prior technology, and binding clip is when connecting the multiply plain conductor, and jaw damages or pinch off part metals lead easily, and conduction property is poor.

The technical scheme that the utility model solves the existing problem of prior art to be provided is, a kind of improvement molded lines binding clip, comprise a pincers sheet and another pincers sheet, the middle part of two pincers sheets is hinged by hinge bar, between the two pincers sheets spring is arranged, it is characterized in that: pincers sheet is that pincers sheet in basis is stainless or the steel plate manufacturing of metal coating is arranged, and another is that conducting pincers sheet is that copper-based material is made, and afterbody has a connecting groove.

Stainless or have the steel plate of metal coating to comprise: stainless steel, stainless iron, copper plated steel, galvanized steel plain sheet, chromium plating steel plate etc.; Basis pincers sheet is the manufacturing of steel metal material, makes the intensity of intermediate plate and rigidity be significantly improved, and gives and makes when particularly assembling, and adopts the big spring of elasticity to provide the foundation; In use, basis pincers sheet guarantees for whole binding clip provides intensity and rigidity, has reduced the problem of clamp deformation effect conducting quality, simultaneously additional conductive.Conducting pincers sheet is the copper-based material manufacturing, and based on conducting, copper-based material should comprise copper and copper alloy, and the method for electroplate can be adopted in special application scenario, strengthens its conduction property.Spring between basis pincers sheet and the conducting pincers sheet can be torsion spring, also can be stage clip.

As preferably, it is characterized in that pincers sheet jaw U-shaped limit, described basis is provided with anti-slop serrations, there is a flanging that makes progress the end.Main effect is when the clipping cylindrical binding post, basis pincers sheet and the direct clamp of conducting pincers sheet.

As preferably, it is characterized in that pincers sheet jaw place, described basis is with an elasticity jaw.Jaw is generally the insulating material manufacturing, and main effect has three: at first be to utilize the characteristics of jaw strain that lead and the bigger contact area of conducting pincers sheet are provided; Next is to utilize the jaw strain to avoid lead by the possibility of pinch off; The jaw that insulate in addition presss from both sides with the basic common insulation joint of insulating case that clamps the sheet afterbody, prevents after the binding clip placement and other conductor conductings.

As preferably, it is characterized in that the elasticity jaw has high outer low trapezoidal hole in, through hole outside height is less than the height of pincers sheet jaw end, basis flanging.This through hole on the jaw mainly is to clamp on the sheet jaw in order to be enclosed within the basis, the flanging height that through hole outside height makes progress less than pincers sheet jaw end, basis, in order that utilize the resilient characteristic of jaw to pass flanging, flanging blocks the elasticity jaw and prevents to withdraw from voluntarily.

As preferably, it is characterized in that being cambered surface above the elasticity jaw that there is low clinohedral in the outer height at the middle part of cambered surface.

As preferably, it is characterized in that conducting pincers sheet jaw is an outer shallow interior dark U-lag, the width of U-lag is greater than the width of conducting pincers sheet body, and the last plane of jaw U-lag and the clinohedral of elasticity jaw offset, and two hypotenuses of U-lag and the cambered surface on the elasticity jaw match.

The width of conducting pincers sheet jaw U-lag makes the rigidity of body increase greater than the width of conducting pincers sheet body, saves material, and bigger jaw is convenient to increase the conducting area.The last plane of U-lag and the clinohedral of elasticity jaw offset, cambered surface matches on two hypotenuses of U-lag and the elasticity jaw, the size of these two contact-making surfaces and jaw distortion is relevant, and emphasis will guarantee that the clinohedral on plane and elasticity jaw has bigger contact pressure on the U-lag.

As preferably, it is characterized in that described basis pincers sheet and conducting pincers sheet afterbody periphery are with an insulating case respectively.The elasticity of these two insulating case materials is little, and preferably there is anti-skidding ripple the outside.

What be highly profitable is: a kind of intermediate plate of modified form binding clip has adopted two kinds of different made according to the attached function of master separately, has lowered cost widely; Increased an elasticity jaw, improved the conduction and the fail safe of product connection flat wire terminal or stranded conductor, this modified form wiring has accompanied the higher cost performance and the bigger scope of application.
