Description

Current wiring terminal

Technical field

The invention belongs to electrical fitting field, be specifically related to a kind of current wiring terminal.

Background technology

Along with industrial automatization is more and more higher, Industry Control requires more and more stricter, accurate, and the consumption of binding post is also going up gradually, and its scope of application is more and more wider, and kind is also more and more.

Current modal connection terminal structure is: comprise matrix, be arranged on conducting strip and electric current engaging means in matrix, these electric current engaging means are mainly top shoe and the sliding block of being controlled relative motion by rotary screw,, when screwing screw, top shoe and sliding block move toward one another, the bridge of connecting as electric current after clamping with conducting strip, realizes energising; When unscrewing screw, top shoe and sliding block counter motion, depart from conducting strip, realizes power-off.The shortcoming of this binding post is mainly: upper and lower slide block is in horizontal sliding process, easy and conducting strip bumps, cause sliding not smooth, do not reach position, when serious, also can puncture binding post, and its top shoe is unexpected dropping on conducting strip easily, there is potential safety hazard, and also more complicated of structure.

Summary of the invention

For above-mentioned deficiency, the invention provides a kind of current wiring terminal, this current wiring terminal can effectively be controlled the position of compact heap, and simple in structure, easy to use, safe and reliable.

The present invention realizes by such technical scheme:

A current wiring terminal, comprises matrix, is positioned at conducting strip and the current switching control device of matrix, and described current switching control device comprises stay, the compact heap being sleeved on whirligig and is positioned at the hold down gag of compact heap top.

Further, described hold down gag is wire clip, and this compression strip is connected with stay, by stay, drives wire clip to move, and realizes electric current and connects and cut off.

Further, described whirligig is rotary screw, and it is socketed on stay, to control stay motion.

Further, described current wiring terminal also comprises the stopping device that is positioned at matrix inside.

Be further, described backing stop structure, its marginal trough place and mounting guide rail are connected, at this current terminal period of the day from 11 p.m. to 1 a.m of dismounting, external force prizes installation foot, and the medial surface at above-mentioned marginal trough place withstands the medial surface of mounting guide rail, and both contact points are as a stress point, prevent that terminal from moving to stressed opposite direction, is convenient to pull down.

Further, a watch window is set on described matrix, and on switch end face on correspondence position in this watch window, current switching indicating device is set, intuitively observe the state that switches on or off of electric current.

Be further, described current switching indicating device is to be arranged on switch end face to show that current circuit is switched on or switched off the character mark of state, when switch slides, the described status word sign that is switched on or switched off only shows a kind of, this character mark can adopt brightly painted redness or green font, operating personnel can be observed the operating state of binding post at a distance, convenient and swift.

Further, position mate is set on described matrix indicates graticule with current switching indicating device, when current switching indicating device moves in matrix, by this position, indicate graticule can intuitively see whether corresponding component slides and put in place.

Be further, one gib block is set on described matrix, on described current switching control device, arrange one and coordinate the chute sliding with described gib block, when current switching control device horizontally slips in matrix, chute is led by gib block, compact heap and conducting strip can not bumped, easily realize laterally and sliding.

Owing to having adopted said structure, current wiring terminal provided by the invention is simple in structure, and compact heap is in sliding process, and motion stabilization, can not collide conducting strip; And, adopt backing stop structure, itself and mounting guide rail mating reaction, quick release lower terminal, convenient and swift, rotary screw is controlled stay elevating movement, and stay drives wire clip elevating movement again, thus being connected of control compact heap and conducting strip is reliable and stable.

Embodiment

In order to be more expressly understood object of the present invention, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the present invention is described further, but protection scope of the present invention is not limited in following examples.

As shown in Figure 1 to Figure 3, a kind of current wiring terminal, comprise matrix 1, be positioned at conducting strip 2 and the current switching control device of matrix 1, described current switching control device comprises stay 5, the wire clip 4 being sleeved on whirligig 3 and is positioned at the hold down gag 6 of guide pad top; This wire clip 4 is connected with stay 5, and described hold down gag 6 is compact heap; Described whirligig 3 is rotary screw, and it is socketed on stay 5, and when rotary screw 3, stay 5 is stressed, makes wire clip 4 liftings, and clamps together with compact heap 6 or unclamp conducting strip 2; Described current wiring terminal also comprises the backing stop structure 7 that is positioned at matrix 1 inside.

Further, above-mentioned backing stop structure 7 is butterfly snap-in structure, and its marginal trough place and mounting guide rail 13 are connected; One watch window 9 is set on matrix 1, with on switch end face on the interior correspondence position of this watch window 9, current switching indicating device 8 is set, for being arranged on switch end face, show that current circuit is switched on or switched off the character mark of state, when switch slides, the described status word sign that is switched on or switched off only shows a kind of, this case adopts " ON " and " OFF " as character mark, be respectively bright-coloured green and red, when switch slides into electric current connection correspondence position, " OFF " character is blocked by matrix 1, and " ON " shows; When switch slides into failure of current correspondence position, " ON " character is blocked by matrix 1, and " OFF " show, thus operating personnel can see intuitively from afar, the operating state of binding post.

Further, the position indication graticule 10 mating with current switching indicating device 8 is set, accurately location on described matrix 1.

One gib block 11 is set on described matrix 1, on described current switching control device, arranges one and coordinate the chute 12 sliding with described gib block 11.
