Abstract
The utility model relates to a conducting bolt for screwing through conductor insulation cortex used for a low voltage electrical apparatus, comprising a screw head (1), a screw thread rod (2), a rotating inter end round hole (3), and a screwdriver groove (4). The device has obvious advantages that when connecting the wire, the conductor cortex is no need to be taken off, with reduced process, fastened operation, improved installation efficiency, convenient operation, reliable practicality, prevented bad contact, and convenient operation with electricity, which can prevent each accidents caused by electric arc and spark, prevent the accidents in the circuit caused by electric leakage, and prevent the bad contact caused in the operation process of the machine and the vibration from the other forces.
Description
The utility model relates to a kind of low-voltage electrical apparatus screw.
Generally connect with lead between the electrical equipment or between the electrical equipment, power supply, safty device, switch, node has is welding, and most cases connects with screw.Existing situation is, when connecting with screw, will divest the insulation cortex (peeling) at terminal place earlier, exposes one little section metal core wire, is inserted in the wire connecting hole, and it is fastening to tighten screw again.With regard to peeling, still time-consuming many though operation is simple to the installation wiring of an engineering, and the easy damaged heart yearn, bad connection is often arranged, even cause electric leakage and accident.When connecting, can not divest the insulation cortex of lead, twist cortex, connect heart yearn with screw with screw, realize " logical " (one is stubborn logical) once twisting?
The purpose of the utility model solves this technical problem just, designs a kind of contact screw of stubborn admittance line insulation cortex, does not divest the cortex of lead, realizes " logical once twisting " (one is stubborn logical).
The structure of the contact screw of the stubborn admittance line insulation cortex that the utility model is released is rationally to bore a last circular hole at the tip (screw terminal) of existing metallic screw, the rounded sharp blade-like of screw terminal, like this, twist when revolving screw, screw in end-grain cutting and cross cortex and metal core wire connection.The utility model is made up of screw head, threaded stem, screw terminal circular hole, and screw head and threaded stem are an overall structure, and screwdriver slot is arranged on screw head.
The utility model has the advantages that significantly: during wiring, need not peel off the lead cortex, reduce operation, sharp work is saved time, and improves installation efficiency; Easy and simple to handle, practical reliable; Prevent bad connection, guarantee to conduct electricity unimpeded; Make things convenient for livewire work, guarantee personal safety; Can prevent from when the operation greatly to produce the various accidents that cause to the long-range livewire work in down-hole and inflammable, explosive, toxic gas and dust solubility because of electric arc and spark; The place bigger to humidity during operation, can prevent to leak electricity and the accident that produces; Can prevent to cause bad connection in the circuit because of vibrations that machinery causes from other strength in running neutralization.Certainly, the utility model is not suitable for big electric current electric consumer.
Fig. 1 is the utility model structural representation (plan view, left view, plan view, worm's eye view and a sectional drawing).
As shown in the figure, the utility model is made up of screw head (1), threaded stem (2), screw terminal circular hole (3), screwdriver slot (4), screw head (1) is an overall structure with threaded stem (2), screwdriver slot (4) is on screw head (1), screw terminal at threaded stem (2) has a screw terminal circular hole (3), the rounded blade-like of screw terminal of threaded stem (2).
Screw head (1) is multiple shape, and as cylindric, trapezoid shaped is decided according to actual demand.Screwdriver slot (4) has cross, single port shape etc.
Generally speaking, the thickness of wire insulation cortex is about 2mm, and the degree of depth of screw terminal circular hole (3) also is about 2mm in the utility model, promptly the degree of depth of this contact screw screw terminal circular hole (3) should with the insulation of suitable lead send out the layer thickness be complementary.
The utility model is made by metallic material.Be suitable for voltage 0-380V, be suitable for electric current 0-15 peace.
Claims (1)
1, twists the contact screw of admittance line insulation cortex, form by screw head (1), threaded stem (2), screw terminal circular hole (3), screwdriver slot (4), screw head (1) is an overall structure with threaded stem (2), screwdriver slot (4) is on screw head (1), it is characterized in that at the screw terminal of threaded stem (2) a screw terminal circular hole (3) being arranged, the rounded blade-like of screw terminal of threaded stem (2).
