Abstract
The utility model relates to a clamping board structure applicable to a circuit switch and a protective device. The clamping board structure comprises an outer shell (1) and a clamping board (2). The clamping board is provided with a guide rail (5) or a plurality of motion guide rails. A reversely fastened elastic clamping piece (4) is arranged in the motion guide rail (5). The bottom of the outer shell (1) is provided with a wavy groove (3) which fits the elastic clamping piece (4). The wavy groove (3) comprises two wave troughs. The clamping board (2) is fixed on the outer shell (1) by buckling the reversely fastened elastic clamping piece (4) and the groove (3). The elastic clamping piece can be dropped out from the groove (3) very easily with the help of an external force, so that the clamping board (2) can be dismantled from the outer shell (1) very conveniently.
Description
Technical field
The utility model relates to relay and field of switches, relates in particular to a kind of clamp structure that is applicable to contactor and protective device.
Background technology
In the application of life; the contactor of circuit such as relay, circuit breaker or protective device often all are mounted on the attachment rail; at this moment it connects and fixes effect between the shell of contactor or protective device and attachment rail just to need a clamp; the structure of snakelike shell fragment is set on the clamp of the prior art usually; this clamp is installed on the shell, and the interface arrangment that matches is arranged on the shell.This clamp can be this contactor or firm being installed on the attachment rail of protective device.
But clamp of the prior art comparatively bothers during from the dismounting of contactor or protective device shell, the contactor of clamp of the prior art or protective device is installed when attachment rail is dismantled, also unusual trouble.
Summary of the invention
For addressing the above problem, the utility model provides a kind of and dismantles easy and be applicable to the clamp structure of contactor and protective device.
The technical solution adopted in the utility model is: a kind of clamp structure that is applicable to contactor and protective device; comprise shell and clamp; described clamp is provided with one or more motion guide rails; it is characterized in that; be provided with the flexible clamp piece of reverse buckling type in the described motion guide rail; described outer casing bottom is provided with the waveform groove that cooperates with flexible clamp piece, and described waveform groove comprises two or more troughs.
Preferred version of the present utility model is, the flexible clamp piece front end of described reverse buckling type is provided with card base, and described card base top is an arc.
Another preferred version of the present utility model is, described clamp both sides are provided with fixed rail, and described shell is provided with the limiting channel with the fixed rail coupling.
A preferred version more of the present utility model is, described clamp front end is provided with ' ten ' and ' one ' font handling hole.
Technical advantage of the present utility model is:
1. adopt the flexible clamp piece of reverse buckling type and the mode of groove fastening that clamp is fixed on the shell, by the help of external force, shell fragment can withdraw from from groove very easily, makes this clamp very convenient from the shell dismounting.
When this contactor or protective device when mounting panel disassembles, by the help of external force, shell fragment can withdraw from from groove easily, clamp breaks away from shell, the end-card connection function makes that the dismounting of this contactor or protective device is very convenient.
Below in conjunction with the drawings and specific embodiments is that the utility model is further elaborated.
Description of drawings
Fig. 1 splits schematic diagram for present embodiment;
Fig. 2 is a present embodiment clamp vertical view;
Fig. 3 is a present embodiment clamp end view;
Fig. 4 is a present embodiment outer casing bottom view;
Fig. 5 is the present embodiment scheme of installation.
Embodiment
With reference to figure 1, Fig. 2, Fig. 4; a kind of clamp structure that is applicable to contactor and protective device; comprise shell 1 and clamp 2; described clamp is provided with a guide rail 5; can also establish a plurality of motion guide rails; be provided with the flexible clamp piece 4 of reverse buckling type in the described motion guide rail 5, described shell 1 bottom is provided with the waveform groove 3 that cooperates in flexible clamp piece 4, and described waveform groove 3 comprises two troughs.The waveform of described waveform groove can be sinusoid, triangular waveform, trapezoidal waveform etc.One of them is fixing trough 10 described two troughs, another be between spacing trough 9, two troughs apart from just in time satisfy product required step down, fixed function.Trough also can be made as more than two, and the trough of increase can further allow bit function.
With reference to figure 2, Fig. 3, Fig. 4, Fig. 5, flexible clamp piece 4 front ends of described reverse buckling type are provided with card base 8, described card base 8 tops are arc.Arcuate structure makes its mould not fragile in manufacture process, and reduces the damage that card base 8 causes because of frictional force and pressure in motion process, prolongs clamp useful life.
Described clamp 2 both sides are provided with fixed rail 7, and described shell 1 is provided with the limiting channel with fixed rail 7 couplings.Described limiting channel is in the both sides of groove 3.Limiting channel can must make firmly that with fixed rail 7 shell 1 and clamp 2 combine.
Described clamp 2 front ends are provided with ' ten ' and ' one ' font handling hole 6.Can adopt cross or Flathead screwdriver to make auxiliary extracting tool.
In process of production, after clamp 2 is fixed on the shell 1, when finding that clamp 1, shell 2 etc. are defective in quality, need be when shell 2 disassembles clamp 1, screwdriver is inserted handling hole 6, this moment card base 8 the position at fixing trough 10, mounting groove 12 directions of exerting all one's strength on shell 1 are moved, card base 8 withdraws from from fixing trough 10.Compared to existing technologies, very convenient.
After attachment rail was installed, perhaps can insert handling hole 6 by screwdriver, and make card base 8 be retracted into fixedly trough 10 at spacing trough 9 position of card base 8 this moment.
Technical staff's notice; though the utility model further describes the utility model according to the foregoing description; but invention thought of the present utility model is not limited only to present embodiment, if be based on the variation of the present utility model thought, all in the utility model protection range.
