Description
Technical field
The utility model relates to junction block, particularly the improvement structure of junction block.
Background technology
The connecting terminal block of large electric current, at frequency converter, uninterrupted power supply, UPS has a wide range of applications on the large-scale refrigeration plant etc.
This connecting terminal block number of poles is indefinite, and each extremely generally has two ports, i.e. mains side and load-side.The circular terminal that the load-side normal operation is being pressed connects, and load-side generally connects in complete machine factory.Mains side generally connects in the use outfield of client, and the normal operation bare wire connects by screw and clamping element.When client connects mains side, lose in order to prevent coming off of terminal screw, maybe might be lost in the great harm that machine intimate causes electric short circuit, generally all require the terminal screw of client that adeciduate conformation function is arranged, namely screw rests on the at any time state of reverse locking all the time when the mains side terminal screw is infinitely unscrewed, for this reason, conventional construction has specially designed lid to realize above-mentioned functions.
Summary of the invention
The improvement structure that is to design a kind of junction block of the present utility model, the project organization by insulating base realize the screw function that do not come off, thereby save part, reduce materials, reduce man-hour, Cost reduction.
For achieving the above object, the technical solution of the utility model is:
The improvement structure of junction block, it comprises, insulating base, the front portion of corresponding load-side is set up in parallel some independently compartments, and accordingly, the installation through hole of some independently up/down perforations is offered at the rear portion of corresponding power side side by side; The front compartment middle part is horizontally disposed with fixed head, establishes interface channel between the compartment of fixed head top and the installation through hole, and the compartment lower inner wall is offered a fixed groove; The outer wall corresponding through hole of installing in insulating base rear portion is also offered for the connection jack in the wire insertion installation through hole waiting; Each installs through hole upper port inwall along circumferentially being convexly equipped with a circle step; Some metal connecting wire frames are arranged at respectively installing in the through hole of described insulating base, and metal connecting wire frame upper surface has connecting screw hole; Some conducting terminals, be arranged between described insulating base compartment and the installation through hole by the interface channel between compartment and the installation through hole, the one end is positioned on the insulating base compartment fixed head, and be fixed on the fixed head by terminal screw and square nuts, a side of square nuts is embedded in the fixed groove of compartment lower inner wall; The conducting terminal other end passes installs the interior metal connecting wire frame of through hole against insulating base fixed frame inwall, and is lock onto on the metal connecting wire frame by lock screw, and the shade on the lock screw is limited under the step that through hole upper port inwall is installed.
The beneficial effects of the utility model
1, the design structure of the utility model by insulating base self realized the screw function that do not come off, and unnecessaryly realizes as the part that increases in addition design in the conventional construction again, thereby saves part, reduces materials, reduces the Cost reduction in man-hour.
2, the wiring of load-side realizes by terminal screw and independent nut.And be directly to cooperate realization with terminal screw at terminal board punching tapping in the conventional construction.Conventional construction be because will taking into account locking intensity, the thickness of terminal board therefore reverse side factor and increase.And because terminal board is generally copper material so torsional strenght is limited.Use separately nut in the utility model structure, so terminal board is as long as set thickness according to the electric current that fixes, thereby reduces the copper material consumption.And because use the steel nut, torsional strenght is strengthened greatly.

Embodiment
Referring to Fig. 1 ~ Fig. 3, the improvement structure of junction block of the present utility model, it comprises, insulating base 1, the front portion of corresponding load-side is set up in parallel some independently compartments 101, and accordingly, the installation through hole 102 of some independently up/down perforations is offered at the rear portion of corresponding power side side by side; Anterior compartment 101 middle parts are horizontally disposed with fixed head 11, establish interface channel 103 between the compartment 101 of fixed head 11 tops and the installation through hole 102, and compartment 101 lower inner wall are offered a fixed groove 12; The corresponding through hole 102 of installing of insulating base 1 rear portion outer wall is also offered for the connection jack 104 in the wire insertion installation through hole 102 waiting; Each installs through hole 102 upper port inwalls along circumferentially being convexly equipped with a circle step 1021; Some metal connecting wire frames 2 are arranged at respectively installing in the through hole 102 of described insulating base 1, and metal connecting wire frame 2 upper surfaces have connecting screw hole 21; Some conducting terminals 3, be arranged between described insulating base 1 compartment 101 and the installation through hole 102 by the interface channel 103 between compartment 101 and the installation through hole 102, the one end is positioned on insulating base compartment 101 fixed heads 11, and be fixed on the fixed head 11 by terminal screw 4 and square nuts 5, a side of square nuts 5 is embedded in the fixed groove 12 of compartment 101 lower inner wall; Conducting terminal 3 other ends pass the metal connecting wire frame 2 installed in the through hole 102 against insulating base 1 fixed frame inwall, and pass connecting screw hole 21, lock onto on the metal connecting wire frame 2 by lock screw 6, the shade 61 on the lock screw 6 is limited in the step 1021 times that through hole 102 upper port inwalls are installed.
The utility model is packed lock screw 6 into and is installed in the through hole 102 from installation through hole 102 bottoms of the pedestal 1 that insulate, installation through hole 102 upper port inwalls by insulating base lock shade 61 on the screw 6 along circumferentially being convexly equipped with a circle step 1021, lock screw 6 is limited in install the step 1021 times of through hole 102 upper port inwalls, realized the screw function that do not come off, unnecessary again as the part realization that increases in addition design in the conventional construction, thereby saving part, reduce materials, reduce the Cost reduction in man-hour.
Simultaneously, cooperating of square nuts 5 on the fixed groove 12 that the utility model is offered by insulating base 1 compartment 101 lower inner wall and the terminal screw 4, a side that is square nuts 5 is embedded in the fixed groove 12 of compartment 101 lower inner wall, thereby terminal screw 4, conducting terminal 3 are fixed on the fixed head 11 at compartment 101 middle parts, the wiring that has realized load-side is by terminal screw and independent nut locking.
And be directly at the terminal board tapping that punches in the conventional construction, cooperate with terminal screw again and realize locking, conventional construction be because will taking into account locking intensity, the thickness of terminal board can so the factor of reverse side and increasing; And because terminal board is generally copper material so torsional strenght is limited.Use separately nut in the utility model structure, so terminal board is as long as set thickness according to the electric current that fixes, thereby reduces the copper material consumption.And because use the steel nut, torsional strenght is strengthened greatly.
