Abstract
A quick clamping module for low-voltage electrical appliances includes an insulation part; a rear side surface of the insulation part is provided with a first clamping pin and a second clamping pin; a rear part of the insulation part is provided with a first elastic sheet embedded groove; a first elastic sheet embedded groove is internally provided with a first elastic sheet; the first elastic sheet includes a corner; the corner protrudes to the rear side surface of the insulation part and is located at an exit of a groove mouth of the first clamping pin; a groove mouth of the second clamping pin is internally provided with a second elastic sheet; the second elastic sheet is internally provided with a trapezoidal notch; and the trapezoidal notch is directed toward the groove mouth of the first clamping pin. In the utility model, the elastic deformation of the insulation part and the mechanical strength of the elastic sheet are used to fix the insulation part on a mounting rail, so that other tools are not needed for tightening and fixing; the installation and repair are convenient; a certain angle is formed between the horizontal surface and the first elastic sheet; and the contact area between the clamping module and the mounting rail is increased, so that the better clamping effect is realized.
Description
Technical field:
The utility model relates to electricity field, relates in particular to the mounting structure of low-voltage electrical apparatus module, particularly a kind of quick clamping module for low-voltage electrical apparatus.
Background technology:
In prior art, low-voltage electrical apparatus module extensively adopts rail formula mounting structure, reliable fixing in order to realize, the insulating part of low-voltage electrical apparatus module adopts bolt tightening to be fixed and clamped on mounting rail, its operation, installation process need the more time, inefficiency, in addition, it is little that bolt compresses contact area, and fastening effect is bad.
Summary of the invention:
The purpose of this utility model is to provide a kind of quick clamping module for low-voltage electrical apparatus, and the described this quick clamping module for low-voltage electrical apparatus will solve the insulating part of prior art mesolow electrical appliance module and the undesirable technical problem of low, the fastening effect of mounting rail joint efficiency.
This quick clamping module for low-voltage electrical apparatus of the present utility model, comprise insulating part, on the trailing flank of described insulating part, be provided with first card base and second card base, in the first described card base and the second card base, all include separately a notch, described notch in described notch and the second card base in the first card base in opposite directions, wherein, the rear portion of insulating part is provided with a first shell fragment embedded groove, in the first described shell fragment embedded groove, be provided with first shell fragment, the first described shell fragment includes an angle, it is outer and be arranged in the exit of the notch of the first card base that described angle protrudes into the trailing flank of insulating part, in the notch of the second described card base, be provided with second shell fragment, in the second described shell fragment, be provided with a trapeze cut, the notch of described trapeze cut in the first card base.
Further, the first shell fragment is square, and described angle is a right angle in square.
Further, the second card base is cantilever-shaped and is connected on insulating part.
Further, the each free metallic plate punch forming of the first described shell fragment and the second shell fragment forms.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model arranges two embedded shell fragments at the insulating part rear side of low-voltage electrical apparatus module, coordinate with the clamping of mounting rail both sides, utilize the elastic deformation of insulating part and the mechanical strength of shell fragment that insulating part is fixed on mounting rail, thereby it is fixing that the instrument that does not need to use other is tightened, install and maintenance operation facilitates; The first shell fragment and horizontal plane have a certain degree, thereby have increased the contact area of clamping module and mounting rail, make to clamp better effects if.

Embodiment:
Embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, quick clamping module for low-voltage electrical apparatus of the present utility model, comprise insulating part 1, on the trailing flank of described insulating part 1, be provided with first card base 2 and second card base 4, in the first described card base 2 and the second card base 4, all include separately a notch, described notch in described notch in the first card base 2 and the second card base 4 in opposite directions, wherein, the rear portion of insulating part 1 is provided with a first shell fragment embedded groove, in the first described shell fragment embedded groove, be provided with first shell fragment 3, the first described shell fragment 3 includes an angle, it is outer and be arranged in the exit of the notch of the first card base 2 that described angle protrudes into the trailing flank of insulating part 1, in the notch of the second described card base 4, be provided with second shell fragment 5, in the second described shell fragment 5, be provided with a trapeze cut, the notch of described trapeze cut in the first card base 2.
Further, the first shell fragment 3 is square, and described angle is a right angle in square.
Further, the second card base 4 is cantilever-shaped and is connected on insulating part 1.
Further, the each free metallic plate punch forming of the first described shell fragment 3 and the second shell fragment 5 forms.
The operation principle of the present embodiment is: utilize the elastic deformation of insulating part 1 that mounting rail is compressed towards the narrow limit of the second shell fragment 5, the first shell fragment 3 is stiff end, the second shell fragment 5 is movable end, mounting rail is subject to the restriction on the second shell fragment 5 narrow limits can not be up and down, and the first shell fragment 3 limits the side direction activity of mounting rail, be firmly fixed on mounting rail thereby make to clamp module.
