Embodiment
Referring to figs. 1 through Fig. 4, the utility model electricity testing ground wire folder embodiment is described further.
A kind of electricity testing ground wire clip assembly, comprise housing 1, housing 1 comprises drain pan 11 and top shell 12, and drain pan 11 and top shell 12 are shared sides, can allow drain pan 11(or top shell 12 like this) carry out rotating, docking around this side, thus reach an effect covered.
In order to ensure that top shell 12 and drain pan 11 can remain sealed state after covering, power transmission line and electricity testing grounding ring being played to the effect of clamping, clamping, therefore a closing component structure 2 is set on housing 1 to achieve the above object.Closing component structure 2 comprises latch part 21 and buckling parts 22, latch part 21 is arranged in top shell 12, buckling parts 22 is then arranged on drain pan 11 accordingly, wherein latch part 21 is provided with back-off 211, preferably back-off 211 to be arranged to wedge shape, buckling parts 22 is then provided with and inserts for latch part 21, and and the sealed mouth 221 of back-off 211 phase clamping, so just can utilize the cooperation being used for realizing latch part 21 and buckling parts 22 of back-off 211 and sealed mouth 221, and then top shell 12 and drain pan 11 cover after just can realize locking action by the cooperation between latch part 21 and buckling parts 22, thus the fastness (i.e. the fastness of housing 1) between top shell 12 and drain pan 11 can be ensured, make to occur folding easily between top shell 12 and drain pan 11 in the process of Long-Time Service, or even situation about being separated, thus can guarantee that the power transmission line be located in housing 1 is in clamped condition all the time, that is the cooperation of latch part 21 and buckling parts 22, make top shell 12 and drain pan 11 can be in the state covered all the time, and then allow power transmission line obtain protection.And the back-off 211 of wedge shape, then can be convenient be inserted in sealed mouth 221, the cooperation advantageously between latch part 21 and buckling parts 22.
Multiple latch part 21 and buckling parts 22 can be set in top shell 12 and drain pan 11, as shown in Figure 1, and ensure that these latch part 21 and buckling parts 22 lay respectively on the different side of housing 1, compared to only arranging single latch part 21 and buckling parts 22, such mode can realize top shell 12 and drain pan 11 from three directions of housing 1 self sealed, fully ensure that top shell 12 and drain pan 11 fastness after sealed.
It is emphasized that, the setting of locking part and buckling parts 22 is not limited to aforesaid way, can also arrange buckling parts 22, and on drain pan 11, arrange latch part 21 in top shell 12, or mutually intersect used in combination, what equally also can realize between top shell 12 and drain pan 11 is sealed, fixing.
Certainly, closing component structure 2 is not limited thereto, shown in Fig. 4 is another kind of locking mode, top shell 12 offers bayonet socket 23, drain pan 11 is then connected with by extension spring 5 barb 24 fastened with bayonet socket 23, after such top shell 12 and drain pan 11 cover, just can be realized mutual sealed by the snap action of barb 24 and bayonet socket 23, thus the fastness between top shell 12 and drain pan 11 can be guaranteed, avoid in the process of Long-Time Service, because there is folding, separation and cause electricity testing ground wire to press from both sides ineffective situation between top shell 12 and drain pan 11.
In addition, it is sealed that common grafting, hasp also can realize between drain pan 11 and top shell 12, do not repeat herein.
Lid and after top shell 12 and drain pan 11 between (i.e. the inside of housing 1) form a cavity 3, as shown in Figure 3, clamp hole 13 and clamp ring hole 14 is offered at the joint of top shell 12 and drain pan 11, clamp hole 13 and clamp ring hole 14 extend on the side that corresponds, whole cavity 3 has just been run through in such clamp hole 13 and clamp ring hole 14, be connected with the external world, power transmission line just can stretch into from the one end in clamp hole 13, stretch out through the other end of cavity 3 from clamp hole 13, clamp hole 13 is utilized to clamp, clamping power transmission line, electricity testing grounding ring then just can be arranged in clamp ring hole 14, and utilize clamp ring hole 14 to realize adhering to electricity testing grounding ring, clamping.
In above-described embodiment, preferably the bore in clamp hole 13, clamp ring hole 14 is made the size suitable with the external diameter of power transmission line, electricity testing grounding ring, or retaining clip string holes 13 and power transmission line, clamp ring hole 14 and electricity testing grounding ring are all in interference fit state a little, can reduce after electricity testing ground wire is clipped in installation, hangs like this, inner power transmission line and electricity testing grounding ring, especially power transmission line avoid the impact of the weather such as extraneous thunderstorm as far as possible; Like this binding force that simultaneously can also strengthen between power transmission line and electricity testing ground wire folder is set, reduce electricity testing ground wire as much as possible and be clipped in slip on power transmission line, ensure that the reliability of power supply.
As the derivative schemes to above-described embodiment, extension 4 can be outwards set up at clamp hole 13 place, and keep the internal diameter of extension 4 consistent with the caliber size in clamp hole 13, so in use, the active area of electricity testing ground wire folder and power transmission line just can be increased by extension 4, reduce further electricity testing ground wire and be clipped in the possibility that power transmission line slides, make stability between electricity testing ground wire folder with power transmission line higher.
It should be noted that, this extension 4 can be the direct tube section 41 in straight-tube shape, also can be the round table-like round platform section 42 in drawing in, be preferably the mixing section be mixed to form of the round platform section 42 of direct tube section 41 and gathering, as shown in Figure 2, so both can increase power transmission line by direct tube section 41, the contact area of electricity testing grounding ring, strengthen frictional force between the two, ensure that electricity testing ground wire folder can not slide relative to power transmission line, also can by the gathering of the inwall of round platform section 42, guide effect, facilitate wearing of power transmission line, the inwall of this round platform section 42 can also be utilized to play certain clamping action to power transmission line simultaneously, coordinate the use of direct tube section 41, the fastness that electricity testing ground wire is pressed from both sides is better.
In addition, some notches 421 can also be offered in round platform section 42, notch 421 extends to and is connected with outside, and ensure the axial consistent of its length direction and direct tube section 41, preferably notch 421 is symmetrical arranged, such round platform section 42 is just separated into flap sheet, as shown in Figure 1, by the acting in conjunction of these flap sheets, the clamping to power transmission line can be realized equally, the object of clamping, and compared to the round platform section 42 without notch 421, the round platform section 42 that this kind is made up of flap sheet also has certain relaxation and the ability of contraction, thus the effect of clamping can be played equally for the power transmission line of some various outer diameters.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
