Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described.It should be noted that in the following embodiments, for the ease of understanding, described many concrete details.Yet those skilled in the art can understand, and the present invention also can not adopt these details and realize.
As shown in Figure 1, a kind of termination 10 comprises shell 100, and this shell 100 is provided with opening 110, is provided with fixed contact 20 in this shell 100.This fixed contact 20 connects main circuit, plays electric action.The placement configurations of this fixed contact 20 is for facing toward this opening 110.Preferably, the position of this fixed contact 20 is made as the centre position facing to this opening 110.
Be provided with sliding tray 120 in this shell 100, wherein be provided with baffle assembly 200.This baffle assembly 200 can be in the interior movement of this sliding tray 120.This baffle assembly 200 is configured to seal this opening 110 at closure state, exposes this fixed contact 20 relative with this opening 110 in open mode.
As shown in Figure 2, this baffle assembly 200 comprises two block protection plates, the first baffle (upper baffle) the 210 and second baffle (lower baffle) 220.In example shown in Fig. 2, the structure of this two block protections plate is identical.Certainly, in other embodiment, these two baffles can adopt the structure that differs from one another, and depend on applied environment.And in about embodiments of the invention, upper baffle and lower baffle are for the orientation in accompanying drawing, the term that adopts for convenience of description, are not to be limitation of the present invention.
The structure of baffle is described as shown in Figure 3.Take the second baffle 220 as example, this baffle 220 can be configured to rectangle, and the one side is provided with the second operation flange 222, is provided with the second spring 224 at relative opposite side.In being arranged on this sliding tray 120, this second operation flange 222 is exposed to this opening 110, and this second spring 224 is fixed on this sliding tray 120 away from a side of this opening, as shown in Figure 4.Like this, when applying active force on this second operation flange 222, this second baffle 220 can move down.The first baffle 210 also is shown in Fig. 4, and as previously mentioned, it is provided with the first operation flange 212, the first spring 214 equally.
On these sliding tray 120 inner bottom parts; also be provided with defining flange 122; it is configured to limit the moving range of this baffle, and soon this first baffle 210 is restricted to above this defining flange 122 and moves, and this second baffle 220 is restricted to below this defining flange 122 moves.The position of this defining flange 122 is corresponding with the position of this fixed contact 20.Preferably, this defining flange 122 be configured to should opening 110 centre positions, and in the both sides of this baffle each corresponding defining flange.As shown in Figure 3, the second flange 228 of this defining flange 122 and baffle 220 both sides (same, also with the first flange 218 of baffle 210 both sides) coordinates and completes spacing action.
As shown in Figure 5, also be provided with time defining flange 124 in this sliding tray 120.Accordingly, be respectively equipped with the first and second auxiliary defining flanges 216 and 226 on this baffle.This first and second auxiliary defining flange cooperation is carried out assist location to baffle.
As illustrated in fig. 1 and 2, this termination 10 also comprises fastening assembly 300, and it is arranged in the chamber 130 of this shell 100.This fastening assembly 300 comprises action bars 310, movable frame 320 and clamp 330.This movable frame 320 and clamp 330 all are connected to action bars 310 belows, wherein, this action bars 310 passes the hole 322 on this movable frame 320 and inserts the space of this framework 320 inside, the lower end of this action bars 310 connects this clamp 330, and namely this clamp 330 is located in the inner space of this framework 320.The space of described movable frame 320 inside also holds the part of this fixed contact 20, and this part is exactly the part that connects external cable or bus.Namely, this movable frame 320 can be regarded as and be enclosed within on this fixed contact 20.
Wherein, can pass the through hole 140 operating operation bars 300 on this shell 100 tops, this through hole 140 is communicated with this chamber 130.It should be noted that term " top " is for the orientation in accompanying drawing, the term that adopts for convenience of description, is not to be limitation of the present invention.In other applied environment, this chamber can be located on different orientation from through hole.
Make this movable frame 320 and clamp 330 to move up and down relative to each other by operating this action bars 310, and this fixed contact 20 move up and down relatively.Equally, the term "up" and "down" here be for accompanying drawing the orientation, adopt for convenience of description, rather than in order to limit the present invention, in other examples, can be also other relative bearing.
This action bars 310, this movable frame 320 and this clamp 330 can be configured to screw element, make this movable frame 320 and clamp 330 move up and down by rotating this action bars 310.Those skilled in the art can understand, and utilize screw thread that rotation is converted into the known trial that translation is this area, repeat no more herein.Although in an embodiment of the present invention, to describe this action bars 310, this movable frame 320 and this clamp 330 and be screw element, yet those skilled in the art can understand, and can adopt any suitable mechanical mechanism to realize the movement of movable frame 320 and this clamp 330.
Fig. 6-13 show the state of embodiments of the invention in multiple different application environment.As previously mentioned, when unused state, this baffle assembly 200 is in closure state, seals this opening 110.
When connecting a cable 1, as shown in Figure 6, apply active force at the second operation flange 222 of this second baffle 220 it is moved down, thereby expose this fixed contact 20 and this fastening assembly 300.Cable 1 is inserted this opening, be positioned at the below of this fixed contact 20.
Then, make this movable frame 320 and this clamp 330 move relative to each other, and move relative to this fixed contact 20, in order to cable 1 is clamped on this fixed contact 20, as shown in Figure 7.
As shown in Figure 6, after connection cable 1, unclamp this second operation flange 222, this second baffle 220 moves up under the effect of spring 224, sealing opening 110.Obviously, owing to having connected cable 1, this baffle assembly 200 can't seal opening 110 fully, but it will be appreciated by those skilled in the art that such sealing is enough to prevent that the operator from touching live part.
Although shown in Fig. 6 and 7, cable 1 is connected to the below of fixed contact 20, yet obviously, also can moves this first baffle 210, and cable 1 is inserted the top of this fixed contact 20, and be clamped between this fixed contact 20 and clamp 330.
Because each parts of this fastening assembly 300 can move relative to each other and move relative to this fixed contact 20, therefore, can adapt to different cable diameter.As shown in Fig. 8 and 9, when the larger cable 2 of connection diameter, by regulate these fastening assembly 300 each parts relative positions and with the relative position of this fixed contact 20, can hold large diameter cable 2.
Similarly, Figure 10 with are connected the situation that connects two cables that illustrates.Before identical; operate respectively the first and second baffles 210 and 220 with connection cable 3 and 4; regulate fastening assembly 300 cable 3 is clamped between this movable frame 320 and this fixed contact 20, cable 4 is clamped between this fixed contact 20 and this clamp 330.
Figure 12 and 13 illustrates connected mode similarly, and just cable 4 changes bus 5 into.
By the description of front, can find out that the present invention can prevent effectively that the site operation people from touching live part, reduced Danger Electric shock risk.And structure of the present invention can adapt to the cable of different-diameter, and two cables (bus) can also be installed simultaneously.
Although be described in conjunction with the preferred embodiments of the present invention before, yet scope of the present invention is not limited to described concrete example, but can change in the defined scope of claim, as displacement, modification and equivalent way.Therefore, scope of the present invention should be interpreted as containing such displacement, modification and equivalent way.
