Embodiment
Be described further with reference to Fig. 1 ~ 6 pair the utility model.
As shown in Figure 1, a kind of easy-to-dismount connecting terminal block assembly, comprise intercalation part 1 and the fixed part 2 of mutual grafting cooperation, the outer wall of fixed part 2 housing 3 is also provided with draw-in groove 4, the housing 3 of intercalation part 1 is provided with the fixture block 5 matched with draw-in groove 4, the inside of draw-in groove 4 and fixture block 5 is provided with for the tensioner unit of tensioner draw-in groove 4 with fixture block 5 accordingly, the tensioner effect degree of tensioner unit becomes positive correlation with the temperature in fixture block 5 and draw-in groove 4, tensioner unit comprises the multiple air bags 6 being located at draw-in groove 4 and fixture block 5 inside, the air bag 6 being located at draw-in groove 4 side inside is crisscross arranged with the air bag 6 being located at fixture block 5 inside, the periphery of multiple air bag 6 is provided with the heat-conducting piece 7 of each corresponding air bag 6 that to be led by the heat of draw-in groove 4 and fixture block 5 inside.
Because the thermal coefficient of expansion of gas is far away higher than the thermal coefficient of expansion of plastics (containment vessel of existing connecting terminal block mostly is injection molding); volumetric expansion will be there is when air bag 6 is heated; in order to increase the deformation of housing 3; can by near the draw-in groove 4 or plastics being used for coated air bag 6 on fixture block 5 surface change the higher kind of elasticity into; so neither affect the overall steadiness of connecting terminal block, also can increase the clamping stability between connecting terminal block intercalation part 1 and fixed part 2.
Describe in detail, some filaments 9 that heat-conducting piece 7 comprises a copper sheet 8 and is connected with copper sheet 8, one end of filament 9 extends at random and is uniformly distributed in housing 3 inside of intercalation part 1 and fixed part 2, the other end is connected with copper sheet 8, copper sheet 8 is curved, multiple air bag 6 is in elliposoidal and between housing 3 outer wall and copper sheet 8, in order to limit the direction of air bag 6 expanded by heating, copper sheet 8 can be arranged on air bag 6 away from draw-in groove 4 or one end of fixture block 5 sidewall, accordingly, copper sheet 8 can be arranged multiple sieve aperture to strengthen the bonding strength of itself and containment vessel, for filament 9, metal that some conductive coefficients are good can be selected (as silver, copper etc.) draw form.
Optimize, the sidewall concavo-convex fluctuating undulate along its length of draw-in groove 4 and fixture block 5, air bag 6 is arranged in the lug boss on sidewall.
In order to extend the useful life of air bag 6, prevent the gas in air bag 6 and plastics from reacting, air bag 6 inside is filled with inert gas, and in the design's example, inert gas is argon gas.
Further, as shown in Figure 1, the outer wall of intercalation part 1 is provided with multiple connection path 11, is provided with annular conductive film in multiple connection path 11, fixed part 2 is provided with the binding post 13 matched with multiple connection path 11, and draw-in groove 4 is close to connection path 11 along the axis of connection path 11 and is arranged.
Intercalation part 1 is provided with for wearing the locking path 10 of penetrating lock screw and for by the buckle 12 of intercalation part 1 with fixed part 2 clamping, in buckle 12 unlike the prior art in the present embodiment, the sloped-end of buckle 12 is to draw-in groove 4 and its sidewall is provided with the pole 14 of being turned back by buckle 12.
Operation principle of the present utility model is: after connecting terminal block grafting completes energising, due to electric discharge or the resistance heat effect at the terminals place of electric wire, the temperature of connection path 11 madial wall is raised, thus periphery housing 3 temperature of intercalation part 1 and fixed part 2 is raised, by being arranged at the filament 9 of housing 3 inside, by the heat conduction of housing 3 inside on copper sheet 8, the one overall thermal deformation that can reduce housing 3, more heat conduction can be given to air bag 6 by two, be filled with inert gas in air bag 6 to be heated and to expand, because air bag 6 is arranged between the lateral wall of housing 3 and copper sheet 8, its towards copper sheet 8 while the stronger reaction force that is subject to from copper sheet 8 of expanding, make the expansion direction of air bag 6 towards housing 3, the i.e. lateral wall of draw-in groove 4 and fixture block 5, draw-in groove 4 and fixture block 5 are close to more, prevent from loosening, when intercalation part 1 will be dismantled with fixed part 2, only need break line power supply, naturally to cool or after artificial hypothermia until it, air bag 6 shrinks, get final product light breakaway plug portion 1 and fixed part 2, very convenient.
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.
