Embodiment
Referring to figs. 1 through Fig. 4, the binding post embodiment of the utility model with pressure-resistant button is described further.
Some electrically conductive contacting devices 4 that the present embodiment comprises insulation crust 1 and arranges in the inner, this electrically conductive contacting devices 4 is with for clamping clamping of electric lead, this is clamped and comprises the first elastic contact blade 5 of the inside reducing of two panels, each clamp on two panels described in elastic contact blade is equipped with towards the pressurized slide plate of button 2, described pressurized slide plate is that outer Eight characters direction is arranged, the sidewall that described insulation crust 1 is clamped relatively is provided with the cable-through hole 11 identical with electrically conductive contacting devices 4 number, another sidewall that described insulation crust 1 is relative with cable-through hole 11 upper surface be provided with along this sidewall to insulation crust 1 moves towards the groove bent, the quantity of described groove is corresponding with electrically conductive contacting devices 4, and described groove is located at the top of clamping, described groove is provided with the button 2 of the elastically deformable matched with this groove shapes, the corresponding rear and front end of described button 2 is connected on insulation crust 1, and the limit, the left and right sides corresponding in addition of this button 2 forms gap with described groove respectively, pressure block 22 is provided with in described button 2 towards the one side of pressurized slide block 51, described pressure block 22 is embedded between two adjacent pressurized slide plates.
According to said structure and accompanying drawing, the bottom of electrically conductive contacting devices 4 from insulation shell is directly snapped in, wherein being arranged on the leg 41 connecting end before and after electrically conductive contacting devices 4 can snap on insulation shell respectively, and in order to make the connection between them more firm, electrically conductive contacting devices 4 is also provided with the cuspidated clamping sheet 7 of band, after this clamping sheet 7 loads insulation shell along with electrically conductive contacting devices 4, not only increase clamping power, and its tip can also form hangnail effect with housing, place electrically conductive contacting devices 4 and depart from insulation shell.
When needs carry out electric lead (not shown in FIG.) install time, electric lead can penetrate from cable-through hole 11, the exposed copper core segment being in front end can be clamped being clamped by the first elastic contact blade 5 of the inside reducing of two panels of joint, form metal conduction, and electric lead is also fixed.
When electric lead is removed by needs from binding post, and in order to protect copper cash, so the mode of directly handle firmly can not be taked to be extracted from binding post by electric lead.Now, the button 2 be arranged on insulation shell can be pressed, because the rear and front end of button 2 is connected with insulation crust 1 respectively, limit, the left and right sides relative in addition and the dual-side of groove form gap, ensure that button 2 can press normally and be out of shape, by being arranged on the pressure block 22 of button 2 towards pressurized slide block 51 one side, in time pressing button 2, convenient extruding pressurized slide block 51, thus two panels first elastic contact blade 5 of clamp joint is opened, facilitate extracting of electric lead.And because the rear and front end of button 2 is all fixed with housing, the generation of the phenomenon that allow one end upwarp the same with prior art can not be made due to Long-Time Service, ensure that the using state stability of button 2, make it more withstand voltage.
Further, the outer surface in described button 2 relative pressure block 22 is provided with depression 21.In depression 21, compliant member can be installed, as rubber, when people press button 2, convenient operation, protection finger.
With reference to figure 4 in order to better fix electric lead, the envelope curve groove being in and clamping to wire hole extension is provided with in described electrically conductive contacting devices 4, described envelope curve groove is made up of the second elastic contact blade 6 that two panels is curling mutually, described second elastic contact blade 6 is connected with the first elastic contact blade 5, when electric lead penetrates from cable-through hole 11, the exposed copper core segment being in front end can be clamped being clamped by the first elastic contact blade 5 of the inside reducing of two panels of joint, the part being coated with insulated hull being in rear end can be fixed by envelope curve groove, reaches the object of stable clamp.
And in order to safety and the stability of electric lead when inserting binding post of workman better can be protected, the two anticreep top boards 8 drawn in are mutually provided with at the top of envelope curve groove, and anticreep top board 8 is tilted to direction of clamping and is arranged with guiding pressing plate 81, when electric lead inserts cable-through hole 11 time, the copper core of bare front end is in the process inserting cable-through hole 11, the effect of guiding pressing plate 81 can be subject to, orientation on the lower side along electrically conductive contacting devices 4 travels forward, and then clamped joint is clamped, to prevent when fast operating electric lead after insertion cable-through hole 11, it is a series of as passed or cannot be clamped the problem that terminal well clamps from binding post top that its front end upwarps and causes, be in the electric lead of rear with insulating covering then due to the effect of anticreep top board 8, can by better spacing in envelope curve groove.
Modified embodiment:
When arranging plural electrically conductive contacting devices 4 in insulation shell, corresponding many buttons 2 meanwhile also can be set, namely be greater than plural button 2.Owing to being formed with gap between the dual-side of button 2 and the dual-side of groove, here gap called after first gap 31 of the dual-side of close insulation shell will be in, and called after second gap, all gaps 32 be between the first gap 31, and the length in the first gap 31 is greater than the length in the second gap 32.
With reference to figure 5, for the front axis side view of modified embodiment, pass through this set, the button 2 being in both sides of edges is made to be more prone to be pressed, and the button 2 mediated inherently possesses good elastic deformation ability, thus reach when button 2 setting is greater than two, each button 2 can by the effect well pressed.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
