Description

The structure-improved of binding post

Technical field

The utility model relates to a kind of structure-improved of binding post, especially for the binding post of the connection wire of the electronic components such as a kind of LED, being particularly related to can complete coated internal structure, to prevent that extraneous dust foreign material from entering, and affect the structure-improved of the binding post of its normal start.

Background technology

Binding post is also referred to as connector, mainly for the plain conductor between connecting electronic part and electronic component (being commonly called as electric wire), or the wire between connecting electronic part and circuit board, this electronic component comprises resistance, electric capacity, inductance, LED, transformer, liquid crystal panel, contact panel etc., with transmission power supply or electronic signal, to facilitate installation and the configuration between electronic product, electronic equipment internal circuit board and electronic component.

At present binding post on the market is of a great variety, generally speaking, traditional wired terminal has an insulation crust conventionally, and most conductive clip frames that are coated on this insulation crust inside, this conductive clip frame is mainly to make with conductive metallic material, have some in order to clamp the elasticity folder of the wire of external electric parts, and some welding foots that are revealed in shell appearance, binding post can be welded on circuit board by described welding foot, and shell appearance has a plug wire mouth, this plug wire mouth can enter shell for the wire of external electric parts, to accept the clamping of the jaws of described elasticity folder.

In addition, for convenient, wire is extracted out in the jaws of the elasticity folder of binding post, be beneficial to change circuit board or electronic component, and convenient for maintaining electronic product or electronic equipment, on the elasticity folder of this binding post, also can arrange one can drive elasticity folder elasticity to open jaws to discharge the portion of touching that pushes away of wire, lift as shown in No. 201110077533.6 " for the operating device of electric connecting clamp " Patent Case description of China, that wherein discloses electric connecting clamp (being the elasticity folder of above-mentioned conductive clip frame) helps slideway (be above-mentioned push away touch portion), in order to drive electric connecting clamp elasticity, open to discharge outer lead, and on insulation crust one-body molded one can to should help slideway by pressure arm, during use, can press the application of force outside pressure arm to this, order about by the inside elastic bending of pressure arm and touch and help slideway, and then drive electric connecting clamp elasticity to open toward chucking power rightabout, reach the effect that wire takes out that is beneficial to.

But, aforementioned Chinese No. 201110077533.6 Patent Case be the one-body molded traditional design that should press pressure arm on insulation crust, because the described crooked place being connected with insulation crust by pressure arm easily produces the concentrated situation of stress, but insulation crust is to make with plastic material mostly, increase on foot the chance that is bent destruction by pressure arm, cause the reliability of its structure, durability is not good enough.

In addition, when pressing knee-joint and be subject to pressed by external force due to this, must produce and can help the elastics wing effect of slideway for touching this, for not interfered by pressure arm, insulation crust carries out elastics wing, described insulation crust with press under the integrated prerequisite of pressure arm, described by thering is obvious gap between pressure arm and insulation crust, and described gap is with the easy spontaneous structure when by pressure arm of insulation crust described in Unitary injection formed in mould, but extraneous dust, foreign material, aqueous vapor especially easily enters insulation crust inside via described gap, and affect its normal start and useful life, improved waiting.

So how above-mentioned problem is forgone, real is this case inventor technical difficulties to be solved place.

Utility model content

Main purpose of the present utility model, being to provide a kind of can affect the structure-improved of the binding post of its regular event by complete coated internal structure to prevent extraneous dust foreign material from entering, to overcome the problems in above-mentioned prior art.

For reaching above-mentioned object, the structure-improved of the utility model binding post, comprise an insulation crust and and be located at the conductive clip frame in this shell, on this shell, there is a plug wire mouth and and press mouth, on this conductive clip frame, corresponding plug wire mouth is provided with elasticity folder, on described elasticity folder, be formed with a jaws, and correspondence presses mouth and is provided with one and pushes away the portion that touches, wherein:

This is pressed mouthful and innerly to push away springing between the portion of touching with this and be provided with one and the button of shell split; Thus, this button can drive and push away described in touching and push away the portion of touching accepting external force, and orders about the keying of described jaws.

Below further illustrate embodiment of the present utility model:

According to above-mentioned primary structure feature, this button is supported by an elastic parts, and springing is disposed at this and presses and mouthful push away between tactile portion with this.
