Abstract

The utility model relates to a fast connector for a terminal box, which belongs to basic electric elements. The utility model is composed of a sleeve barrel, a plug lid, etc., wherein, an elastic trip is arranged on the side upper part of the sleeve barrel, a clamping block and a clamping groove are arranged on the sleeve. The barrel wall of one side of the sleeve barrel which is opposite to the elastic trip is also provided with a clamping block and a clamping groove. The sleeve barrel can be arranged on a hole of the terminal box fast and conveniently, providing time saving and labour saving tubing operation for distribution channels. The plug lid is chocked on the upper end of the sleeve barrel for preventing slurry from flowing into the distribution channels at grouting time, maintaining integrity of the openings of the distribution channels and preventing wire cuticle from being damaged at distributing time.

Description

Fast connector for terminal box

The utility model relates to the snap joint that a kind of electrical junction box is used.

Traditional electrical junction box A and distribution pipe B be in when construction (see figure 1), before this with the end B of distribution pipe B ₁Directly penetrate in the hole A1 of terminal box A.For preventing that distribution pipe B breaks away from hole A ₁, also mud flows into distribution pipe B inside in order to prevent to be in the milk, must be with blowtorch with pipe end B ₁Roasting soft and flattening makes its mouth of pipe sealing.When finishing the grouting operation, in the time of need distribution, must relend assistant engineer's tool again and carry out secondary operation and be about to flat-shaped pipe end and excised, this secondary operation is rather wasted time and energy, and when the operation in summer, toasted by blowtorch first, and second the space is very little in the terminal box, and pipe end B ₁Within this box, the excision of its pipe end can only be used conventional tool such as iron hammer and chisel, can't be with pipe end B ₁Trim and produce the mouth of pipe of zigzag, stay sharpened edge, and then electric wire appearance insulating barrier is cut when causing distribution, danger such as electric leakage, short circuit occur to cause the mouth of pipe.

The purpose of this utility model provides a kind of joint of novel terminal box, when reaching construction fast, convenient and guarantee that the electric wire appearance is not hurt.

The technical solution of the utility model is as follows: as shown in Figure 2, the snap joint of the utility model is made up of a sleeve 1 and gag 2 elements such as grade, and wherein gag comprises three parts: the middle part is oblate column; Top is the last wall 21 of an available finger or clamp clamping; The bottom is a following wall 22, and an inserted block 23 is protruded at its two ends.Sleeve 1 is the cylinder of a hollow, and a ring-type convex wall 11 is protruded in its upper end, and the relative position on the wall of the bottom of ring-type convex wall respectively has a groove 12, to match with above-mentioned inserted block 23.Like this, when gag being covered the sleeve upper end, this inserted block 23 just may be stuck in the groove 12 of ring-type convex wall, and gag is tightly covered on the mouth of pipe of sleeve 1 upper end.Side in the upper end of sleeve 1, be provided with two grooves 14 that run through barrel, accompany a flexure strip 15 between these two grooves, the top of this flexure strip has an end face to make the planar fixture block 17A of circular arc, form a draw-in groove 18A below the fixture block, fasten (see figure 4) with hole wall with terminal box, the outer edge surface 16A of this flexure strip, pushes for finger for protruding easily than sleeve wall; Consider that from stressed angle also protruded an outer edge surface 16B with outer edge surface 16A symmetry in the opposite side respective heights of sleeve, the while also is provided with a fixture block 17B and draw-in groove 18B at this opposite side, so that the hole wall of terminal box fastens.Making reticulate pattern or straight burr 13 on the outer wall of sleeve pipe, can be netted groove or straight trough or annular groove also, and being increases the frictional force of palm and overcoat in order to assemble in order to assembling, also is in order to increase the adhesion of solidifying of be in the milk rear sleeve and mud.Fig. 5 is the procedure chart in the terminal box that sleeve is packed into, gag has been positioned on this moment on the sleeve to prevent that grouting from flowing into from the sleeve upper end mouth of pipe; Earlier draw-in groove 18B is stuck in the wall edge in the hole 31 of terminal box 3 then, then gently press outer edge surface 16A with the finger application of force, flexure strip is sloped inwardly, the application of force pushing sleeve tube that makes progress simultaneously, then fixture block 17A can be slipped in the hole 31 easily along its arc surface, finish so sleeve 1 promptly combines with the hole 31 of terminal box 3, then distribution pipe 4 can be held under sleeve 1 and be inserted in the sleeve, thereby finished the pipe arrangement construction operation of terminal box 3 with the distribution pipe.

Advantage of the present utility model is as follows:

The first, easy to assembly: as by the fixture block on the flexure strip and draw-in groove and corresponding fixture block and draw-in groove, can sleeve to be installed in the hole of terminal box quickly and easily, and then the saving time of terminal box and distribution pipe, labour-saving pipe distribution operation are provided.

The second, reliable operation:,, can prevent effectively that mud from flowing in the distribution pipe because gag can closely cover the sleeve upper end completely in the filling stage.In the distribution stage, because the distribution mouth of pipe is complete, no sharp-pointed edge, the damage of electric wire epidermis when having stopped distribution.

Provided embodiment of the present utility model in conjunction with following Fig. 2 to Fig. 6:
