Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
By Fig. 1 composition graphs 2, shown in 3, a kind of contactor, comprise housing 1, described housing 1 comprises leg 11, be provided with the housing bottom surface 12 of installing rack 2 and be provided with the housing side 13 of buckle 3, described installing rack 2 is provided with groove and tongue 21, described buckle 3 comprises fixed part 31, connecting portion 32 and pothook 33, described fixed part 31 is connected with pothook 33 by connecting portion 32, described pothook 33 coordinates the chute 14 being formed and be used for passing for guide rail with the groove and tongue 21 on installing rack 2, described connecting portion 32 is located at the top of housing bottom surface 12, and (it is referring to accompanying drawing 3 that connecting portion is located at above housing bottom surface, not for real work position, lower same) and and between housing bottom surface 12, form clearance groove 15, gap slot 16 is provided with between described connecting portion 32 and leg 11, described gap slot 16 extends to housing side 13, described connecting portion 32 is connected with housing side 13 by fixed part 31, described buckle 3 is integral type structure with housing 1, primary importance when described pothook 33 has an installation and pressing buckle 3 make pothook 33 rotate the second place unlocked.The position that special instruction buckle is fixedly connected with housing is referred to as fixed part, and connecting portion refers to the part of buckle except pothook and fixed part, mainly plays the effect of connection grab and fixed part.The beneficial effects of the utility model are, buckle and housing are integral type structure, and overall processing is shaping, processing, production efficiency is high, and production cost is low, and buckle does not need to install with on housing by other parts now, high efficiency of assembling, reduces cost indirectly; By the architectural feature of buckle and housing, when needing dismounting, direct control is just passable have been dismantled, and makes product dismounting, easy to maintenance, provides convenience for client uses.
Described connecting portion 32 is provided with the solution lock dog 34 that pothook 33 is unlocked.As shown in the figure, the utility model is that mode pothook being rotated by separating lock dog realizes buckle unblock, specifically, described connecting portion 32 protrudes downwards in outside, housing side 13 to be formed separates lock dog 34, and the both sides of the junction of fixed part 31 and connecting portion 32 are located at by described solution lock dog and grab.Do not take the space of whole installation like this, unlock pressing and facilitate again.If do not examine empty installing space, then can level protrude.Such structure makes product easy accessibility, fixing reliable, improves efficiency of assembling, indirectly decreases cost.
Described gap slot 16 is in youngster's font on housing side 13, and specifically, the tail end of gap slot outwards forms arc sections 161 on housing side.To wide narrow above under this place connected, can firmness be ensured like this, simultaneously the better elasticity of guarantee tool again, easily press.Described gap slot 16 is provided with bending part 162 at leg 11 place of housing 1.Gap slot stays and does material deformation use, steps down during dismounting, and dynamics during assembling and position better, naturally can be shunk inwards owing to there is gap slot after processing injection moulding, form the position required for clamping.This structure is more conducive to part processing, and injection molding process material flowability is better, and smoothly, inside parts matter is evenly close, toughness and intensity better.
Described connecting portion 32 caves inward and forms groove 35.Such structure makes material uniform wall thickness after Product processing, and the part ductile strength of processing is better, increases area of dissipation simultaneously, slows down material aging, extends the useful life of product.
Reinforcement 36 is provided with between described fixed part 31 and connecting portion 32.Such structure makes product strength better, long service life.
