Abstract
The utility model provides a knife switch protection cover which comprises a protection cover body, a contact pedestal, a switch knife holding tank, and a wiring opening, wherein the switch knife holding groove and the wiring opening are respectively disposed on the protection cover body. The contact pedestal is equipped with a chute. The protection cover body is connected to the contact pedestal through the chute. The protection cover body is scientific in design, convenient to use, not liable to get an electric shock, and high in safety.
Description
Technical field
The utility model relates to a kind of plug-in strip protective device, specifically, has related to a kind of knife switch protective cover.
Background technology
Although original knife switch also has protective cover, when wiring, protective cover need to be taken off, make contact outside exposed, the area of contact human body increases greatly, very dangerous; Can't see in use inner case, the faults such as obvious short circuit can not directly be seen simultaneously.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, thus provide a kind of design science, easy to use, be difficult for to get an electric shock, safe knife switch protective cover.
To achieve these goals; the technical scheme that the utility model adopts is: a kind of knife switch protective cover; comprise guard shield body, contact base and be arranged at plug-in strip holding tank and the wiring opening on described guard shield body; be provided with chute on described contact base, described guard shield body is connected on described contact base by chute.
Base the above, described wiring opening part is provided with capping, described capping is movably connected on described guard shield body.
Base the above, be provided with two pin-and-holes along the chute direction on described contact base, on described guard shield body to being provided with movable pin by two pin-and-holes.
Base the above, be provided with two draw-in grooves along the chute direction on described contact base, on described guard shield body to being provided with clamp by draw-in groove.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model makes between guard shield body and contact base and is slidably connected, when the needs wiring, the guard shield body upwards is pushed into and exposes splicing ear along chute, by pin or clamp, be fixed, carry out wiring work, after carefully connecting the wire, the guard shield body is pushed to normal position downwards along the chute direction, by pin or clamp location, close capping simultaneously, it is farthest protected, facilitated operating personnel's observation, it has design science, easy to use, be difficult for getting an electric shock, safe advantage.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
In figure: 1. guard shield body; 2. contact base; 3. wiring opening; 4. capping; 5. plug-in strip holding tank.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of knife switch protective cover comprises guard shield body 1, contact base 2 and is arranged at plug-in strip holding tank 5 and the wiring opening 3 on guard shield body 1 that be provided with chute on contact base 2, guard shield body 1 is connected on contact base 2 by chute.In the present embodiment: guard shield body 1 can slide up and down along the chute direction, and the volume of guard shield body 1 is slightly larger than contact base 2, in it can being wrapped in, make guard shield body 1 slide without hindrance, simultaneously, the wiring opening is arranged at afterbody the corresponding inner binding post setting of guard shield body, wiring opening 3 places are provided with capping 4, capping 4 is movably connected on guard shield body 1, in the present embodiment, the wiring opening part is provided with chute, capping 4 is slidably connected in chute, capping 4 can open or close according to service condition, when wiring, need larger operating space, it is slided, be convenient to wiring, after taking over line, it is closed, only there is wire to stretch out from the wiring opening, safer, be provided with two pin-and-holes along the chute direction on the contact base, on the guard shield body to being provided with movable pin by two pin-and-holes, when needs connect wire, will be sliding on guard shield body 1, and with movable pin fixed position, then start wiring work, after wiring, extract movable pin, guard shield body 1 is glided, and fix normal the use with movable pin, guard shield body 1 is made for transparent insulating material, and the handled easily personnel observe internal state, finds in time the internal faults such as short circuit.
The difference of the present embodiment and embodiment 1 is: be provided with two draw-in grooves along the chute direction on contact base 2, on the guard shield body, to being provided with clamp by draw-in groove, the benefit of doing like this is: clamp is more prone to operation, has reduced operating personnel's workload.
In other embodiments, capping can be articulated in the upper end of wiring opening, opens or closes as required.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or the part technical characterictic is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
