Description
Technical field
The utility model relates to a kind of binding post of low-voltage circuit breaker, is used for being electrically connected of low-voltage circuit breaker, belongs to the conducting system of low-voltage circuit breaker.
Background technology
Low-voltage circuit breaker is a Primary Component in the distribution system, as the protections such as overload, short circuit and under voltage of circuit and electric equipment.The low-voltage circuit breaker middle connecting terminal is used for the cable of distribution system and being electrically connected of low-voltage circuit breaker, its structures shape the distribution system cable whether reliable with being connected of low-voltage circuit breaker, whether install convenient and efficient.Existing low-pressure plastic shell circuit breaker connection terminal structure is generally installed nut with a plastics blocking with one and is navigated in the groove of base, utilize the groove of base to come setscrew nut, be connected fastening with cable in the distribution system low-voltage circuit breaker line bank with screw and nut then, but this plastics blocking easy deformation, change in size is bigger in the course of processing, and generally all do not have reliable location, cause to come off easily after the installation or in case install and just be difficult to take out.The low-voltage circuit breaker mounting means requires flexible and changeable, and existing this connection terminal structure installation is loaded down with trivial details, has brought unnecessary trouble and potential safety hazard to practical application.
Summary of the invention
The purpose of this utility model provide a kind of safe in utilization, easy for installation, dismounting is simple, the binding post that satisfies the low-voltage circuit breaker of various mounting meanss.
The technical solution adopted in the utility model is: in the base turnover arbitrary utmost point wiring in line two ends one open slot is arranged partly, line bank is arranged on the upper space of open slot, the terminal working of plastics is between line bank and base end face, nut is arranged in open slot and terminal working of plastics, the terminal working of plastics is one to have sidewall, the U type structure of roof and diapire, the positive stop lug boss that has at least one to cooperate in terminal working of plastics sidewall opening direction with the nut appearance profile, roof has a groove that cooperates with the nut appearance profile, have first on the diapire, the second circular positive stop lug boss and a circular groove, base end face has first, second limited impression is respectively with first, the second circular positive stop lug boss matches.
The utility model compared with prior art, and is easy for installation, use reliably, and dismounting is simple, can easily realize the various different installation of low-voltage circuit breaker.

Embodiment
Shown in Fig. 1-4, this binding post comprises terminal working of plastics 1, nut 4, base 2 and line bank 3.Arbitrary utmost point wire connecting portion is arranged with an open slot 21 at base 2 turnover line two ends, the interior shape profile of open slot 21 and the appearance profile of nut 4 are complementary, these open slot 21 degree of depth are greater than or equal to the thickness of nut 4, guarantee that nut 4 can pass in and out the line direction from circuit breaker and enter into this open slot 21.Open slot 21 is arranged between line bank 3 and the base end face 22, and line bank 3 is at the upper space of open slot 21.The degree of depth of open slot 21 to the base 2 bottom surface degree of depth, guarantees that base 2 has connection at the wiring position less than line bank 3, guarantees that also end base 2 has enough mechanical strengths.
Terminal working of plastics 1 is one to have sidewall 11 and the roof 12 that extends along sidewall both sides equidirectional and the U shape materials and parts structure of diapire 13, distance is not more than breaker connection row 3 and arrives base bottom surface 22 height between roof 12 and the diapire 13, at the positive stop lug boss 111 that sidewall 11 opening directions of terminal working of plastics 1 have at least one to cooperate with nut 4 appearance profiles, the terminal working of plastics is between line bank 3 and base end face 22.Positive stop lug boss 111 and 21 actings in conjunction of base openings groove with nut 4 envelopes in base 2; On roof 12, have one with the same groove 121 of sidewall 11 upper limit boss 111 profiles, with the nut 4 of stepping down; And first, second a circular positive stop lug boss 132,133 and circular groove 131 is arranged on the diapire 13, the degree of depth of this circular groove 131 is less than the thickness of diapire 13, but make on the diapire 13 by these circular groove 131 thin column that forms 135 stressed abates, see shown in the dotted line of Fig. 3, be used for the plug-in type wiring behind of circuit breaker; First, second circular positive stop lug boss 132,133 matches with first, second limited impression 221,222 on the base end face 22, the location that guarantees terminal working of plastics 1 is reliable, away from an end of opening direction one open slot 134 is arranged at diapire 13, dismounting in order to terminal working of plastics 1, when dismounting, insert from this open slot 134 with instrument at the back side at base 2, to exerting oneself a little with terminal direction of insertion rightabout, can realize the disassembled simply of binding post.
