Embodiment
Fig. 1 and 2 illustrates according to connection of the present invention and terminal box, and its integral body illustrates with label 1.
Rise two pairs of cylindrical shape handle seats 5 with respective through hole 6 from diapire 2, these through holes 6 (having screw thread) can be admitted fixture such as screw or bolt, with capping and/or the scaffold that is fixed for switch and outlet.In every pair of handle seat 5, the first handle seat contacts with the shorter side wall of box, and the second handle seat is positioned at first handle seat next door in the vertical.The part at handle seat 5 places has the slit 7 that is designed to allow special locking device (itself is known, not shown in the drawings thus) to pass through in the sidewall, and this locking device is protruding box 1 is clogged to the wallboard of mortarless wall.
A plurality of destruction wall sections (knock-out wall section) are formed in the diapire 2 and sidewall 3 of box.As example, box 1 has 8 destruction wall sections 10.Four wall sections 10 are arranged in two main sides of sidewall 3 in the position respect to one another in pairs, and four wall sections 10 are arranged in the diapire 2 and aim at the respective wall section of sidewall 3 in addition.
As shown in Figure 1, the shape of the profile of the wall section 10 of sidewall 3 and diapire 2 forms the circular arc 11 that is arranged in far-end with respect to the joint line 15 between diapire and the sidewall 3.Form the radius of curvature of the profile of circular arc 11 according to the minimum diameter selected shape that is inserted into the corrugated conduit in the box 1.
The destruction wall section 20 of bigger basic U-shaped is provided with around each wall section 10.Bigger wall section 20 also has the contour shape of coaxial circular arc 21, and its diameter is greater than the diameter of the profile of the circular arc 11 that forms less wall section 10.Like this, big wall section 20 also can remove, and admits and has larger-diameter pipeline to stay bigger hole.
Very clear, according to the diameter of pipeline available on the market, can the wall section of size than the 3rd basic U-shaped of the second wall Duan Gengda be set around big wall section 20, or the like.
As shown in Figure 3, big wall section 20 is recessed slightly with respect to sidewall 3 or diapire 2, and less wall section is recessed slightly with respect to big wall section 20.What like this, form two basic U-shapeds with less thickness weakens line 12 and 22; Say so accurately and weaken profile 12 and weakening profile 22 than second between big wall section 20 and sidewall 3 or the diapire 2 in less wall section 10 with than first between the big wall section 20.
The flexible tongue 30 that keeps is arranged to aim at every pair of wall section 10 on sidewall and the diapire, and near the joint line between sidewall 3 and the diapire 2.As shown in Figure 3, keep tongue 30 to be arranged to tilt basic 45 ° with respect to diapire 2 and sidewall 3.In diapire 2, below the maintenance tongue 30 slit 31 is set, makes to keep tongue 30 in slit 31, crooked also elastic return to arrive initial position.
Fig. 3 illustrates the ripple protection pipeline 40 of the type of the connection that is usually used in terminal box 1.Pipeline 40 in inboard hollow so that cable can pass transmission current.Corrugated conduit 40 has basic square-wave form in axial cross section, it has the protuberance 41 that replaces with a plurality of recesses 42.Protuberance 41 has outside diameter d 1, and recess 42 has the outside diameter d 2 less than d1.
As example, corrugated conduit 40 has minimum outer diameter, for example d1=20mm.In the case, if the end of pipeline 40 is inserted in the hole of sidewall 3, then by making it weaken the less wall section 10 that line 12 fractures destroyed and removed sidewall, in sidewall 3, to stay hole.
As shown in Figure 4, insert in the hole that stays in the sidewall 3 end of pipeline 40.By keeping inclination and the possible bending insertion that make things convenient for pipeline of tongue 30 in slit 31.As a result, thus keeping tongue 30 to be easy to elastic return also upwards pushes away pipeline 40 to original position.Thereby its top backup with pipeline 40 limits the crooked outline 11 that forms less wall section 10.
So crooked outline 11 tightly is engaged in the recess between two protuberances 41 42 of pipeline 40.With crooked outline 11 position relative along diameter in, the end that keeps tongue 30 also kayser in the recess between two protuberances 41 42 of pipeline 40.Like this, corrugated conduit 40 secure fixation are to box 1, and prevent the extraction of pipeline or unclamp because of carelessness by the position that keeps tongue 30.In fact, for pipeline 40 is separated with box 1, user's (may utilize pointed tool) must crookedly keep tongue 30 and spur pipeline 40 subsequently.
Very clear, in order to be blocked by the incompatible realization of the close-fitting of pipeline 40, the thickness that limits the crooked outline 11 of the hole that is stayed by removing of wall section must be less than the width of the recess 42 of corrugated conduit.
Has bigger outside diameter d 1 at pipeline 40, for example under the situation of d1=25mm, the second wall section 20 of box is destroyed, then pipeline inserted in the hole that is stayed by the second wall section 20, and by maintenance tongue 30 with by destroying large dia warp profile 21 maintenances that the second wall section 20 stays.
As example, the layout of wall section 10,20 shown in the drawings is can utilize single maintenance tongue 30 not only to be used for the wall section on the sidewall 3 but also to be used for respective wall section on the diapire 2.But obviously the present invention is not limited to the quantity and the layout thereof of wall section.In fact, box 1 can have any amount of wall section that is arranged in by any way on the diapire 2 and/or on the sidewall 3, and wherein each wall section 10,20 limits the edge 11,21 that forms the basic bending relative with corresponding maintenance tongue 30.
Although will keep tongue 30 to be described as basic elasticity in the above description, even they are rigidity basically, they also can finish its function.
