Embodiment
Below in conjunction with the drawings and specific embodiments, to the sting device of cable of the present invention and comprise that structure and the principle of the cable grounding device of this sting device carry out labor.In each accompanying drawing, identical part is carried out mark with identical label.
At first, referring to Fig. 1 to Fig. 3, be the schematic diagram of the first execution mode of the sting device of cable of the present invention.Wherein, Fig. 1 is the schematic perspective view of the first execution mode of the sting device of cable of the present invention, and Fig. 2 is the cross sectional representation of sting device among Fig. 1, and Fig. 3 is that sting device pierces through the insulating sleeve of cable and the schematic diagram that electrically contacts with outer conductor among Fig. 1.As Figure 1-3, in this execution mode, sting device comprises that the first blade 100 made from conductor material and the second blade 200, the first blades 100 and the second blade 200 symmetries are installed on the connecting portion 300 made from conductor material.The first blade 100, the second blade 200 and groove 400 of connecting portion 300 common formation, groove 400 is used for piercing through at sting device the part of the insulating sleeve 510 rear accommodating cables 500 of cable 500, as shown in Figure 3.The first blade 100, the second blade 200 and connecting portion 300 can be to interconnect after preparing respectively to form, and be integrally formed in the time of also can being preparation.The first blade 100 and the second blade 200 are with respect to the longitudinal centre line left-right symmetric of groove 400 and be parallel to each other, the cross section that is groove 400 takes the shape of the letter U, and herein, U-shaped refers to the U font of broad sense, the inner surface that namely consists of the connecting portion 300 of U-shaped bottom surface can be curved surface, also can be to face directly.Easily understand, under the prerequisite that does not affect implementation result, the first blade 100, the second blade 200 also can angledly arrange.
In the present embodiment, the first blade 100 and the second blade 200 are single-edge blade, and namely their medial surfaces separately are the plane, and lateral surface is all with the blade face 110,210 that tilts.
The two ends of the first blade 100 and the second blade 200 blades can be right angle, wedge angle or fillet.Preferably, the blade two ends that do not injure 520, two blades of outer conductor for ease of blade when thrusting insulating sleeve are preferably fillet.
As Figure 1-3, in the ideal case, the distance D between the blade tip of the blade tip of the first blade 100 and the second blade 200 equals the external diameter of the outer conductor 520 of cable 500.At this moment, when the sting device in the present embodiment was used for cable grounding, the first blade 100, the second blade 200 can penetrate respectively the insulating sleeve 510 of cable 500, and just contact with the external diameter both sides of outer conductor 520, can not injure outer conductor 520 simultaneously.
Yet in actual conditions, the distance D between the blade tip has manufacturing tolerance with the nominal value of relative its design standard of outer conductor 520 external diameters, and this manufacturing tolerance is between limes superiors deviate and limit inferior deviate separately.Therefore, in actual conditions, to achieve the object of the present invention, the nominal value of the distance between the blade tip of the blade tip of the first blade 100 and the second blade 200 adds that the nominal value of external diameter that its limes superiors deviate should be equal to or slightly less than the outer conductor of cable deducts its limit inferior deviate.Thereby make the actual value of two blade tip distances, be equal to or slightly less than the actual value (referring to Fig. 3) of the external diameter of outer conductor.As shown in Figure 4, be the actual value D ' of the two blade tip distances schematic diagram when being slightly less than the actual value of outer conductor external diameter.
Preferably, the nominal value of the distance between the blade tip of the first blade 100 and the second blade 200 adds its limes superiors deviate, the nominal value of external diameter that is not less than the outer conductor 520 of cable 500 deduct its limit inferior deviation difference 90%.This be because, the design has utilized the dimension difference of insulating sleeve 510 external diameters and outer conductor 520 external diameters that blade can relatively be cut near the circle center when cutting insulating sleeve 510, circle basic because of blade and outer conductor 520 is tangent when cutting outer conductor 520, make blade not cut bad outer conductor 520 but slip over from its cylindrical, therefore need to the lower limit of this value be limited.
Referring to Fig. 5, Fig. 6, for to the mechanical analysis schematic diagram of execution mode among Fig. 4 in application.Wherein, Fig. 5 is the mechanical analysis figure before the sting device of this execution mode thrusts cable; Fig. 6 is the mechanical analysis figure of the sting device of this execution mode when thrusting in the insulating sleeve of cable.Particularly, as shown in Figure 5, before the insulating sleeve 510 of the first blade 100 of sting device and the second blade 200 cables 500 to be cut, be applied to the active force f on this insulating sleeve 510, can be decomposed into radial component f
DirectlyAnd tangential component f
Cut, f wherein
DirectlyFor causing the destroyed power of insulating sleeve 510, the pass of itself and f is f
Directly=f*cosa, wherein, a is active force f and radial component f
DirectlyBetween angle.Guaranteeing that sting device is cut wears insulating sleeve 510, f
DirectlyMust be greater than making insulating sleeve 510 that yield deformation and destroyed power occur.
Further, with reference to figure 6, owing to closely linking to each other between insulating sleeve 510 and the outer conductor 520, therefore, in actual mechanical process, active force f necessarily also can exist in a flash and can't change what insulating sleeve 510 was cut brokenly, suppose that this moment, transient force was F, then F=f.Similarly, F also can be decomposed into tangential component F
CutAnd radial component F
DirectlyWherein F be directly for may cause the destroyed power of outer conductor, and the pass of itself and F is F
Directly=F*cosA, wherein, A is directed force F and radial component F
DirectlyBetween angle.
Because the diameter of insulating sleeve 510 is greater than the external diameter of outer conductor 520, therefore, A＞a, so, (f
Directly=f*cosa)＞(F
Directly=F*cosA); Simultaneously, because insulating sleeve 510 is plastic material, and outer conductor 520 is metal material, therefore sting device will destroy the required radial load of outer conductor 520 necessarily greater than destroying the required radial load of insulating sleeve 510.
Simultaneously, contact with the good of outer conductor 520 and without damaging for realizing sting device, in sting device in this embodiment and cable insulation jacket 510 and outer conductor 520 contact processes, elasticity and plastic deformation also are the key factors that need are considered.
Specifically with reference to figure 7 and Fig. 8, wherein, Fig. 7 is that the sting device of this execution mode thrusts being used for before the cable and illustrates that elastically-deformable mechanical analysis figure, Fig. 8 are that the sting device of this execution mode is used for illustrating elastically-deformable mechanical analysis figure when thrusting in the insulating sleeve of cable.As shown in Figure 7, when sting device acts on the insulating sleeve 510, guarantee that it can insulation-piercing sheath 510, the radial effect power g of the blade tip of 510 pairs of sting devices of insulating sleeve
Directly' (it is that blade tip is to the radial effect power g of insulating sleeve
DirectlyReaction force) horizontal component, must be less than making the first blade 100 and the second blade 200 that the power that elastic deformations depart from original track occur.Similarly, as shown in Figure 8, when sting device acts on the outer conductor 520, guarantee that outer conductor is not damaged, the active force G of 520 pairs of blade tips of outer conductor
Directly' (it is that blade tip is to outer conductor radial effect power G
DirectlyReaction force) horizontal component, must be greater than making the first blade 100 and the second blade 200 that elastic deformations occur and departing from the power of original track.
Therefore, the state of sting device incision cable is: when sting device contacts with insulating sleeve 510, the power f that applies at sting device makes its insulation-piercing sheath 510, and cut wear after in a flash, f keeps original size, as previously mentioned, f can continue to keep and be applied on the outer conductor 520, and the power that while outer conductor 520 bears does not cause it destroyed.And to make sting device relatively easily the condition of insulation-piercing sheath 510 be that the first blade 100 and second blade 200 of sting device is preferably enough thin, be that blade is enough sharp, the required power f of incision will be enough little like this, thus so that the reaction force g of 510 pairs of the first blades 100 of insulating sleeve and the second blade 200
Directly' horizontal component depart from the power of original track and make blade cut smoothly insulating sleeve less than making the first blade 100 and the second blade 200 that elastic deformations occur.
When sting device insulation-piercing sheath 510 and with after outer conductor 520 contacts, can realize electrically contacting of cable and sting device.But, in actual applications, because error, the error of sting device size and the scale error of whole system of cable assembly size can cause sting device can't accomplish just to contact with outer conductor just to stop to advance.Therefore, more reliable scheme is in the reality, at the first blade 100 of sting device and the second blade 200 with after outer conductor 520 contacts, can move on, and the first blade 100 and the second blade 200 flick to both sides, outer conductor 520 is wrapped in the centre, thereby realize contacting more reliably with outer conductor 520.By above analysis in conjunction with Fig. 8 as can be known, guarantee that the first blade 100 and the second blade 200 successfully flick to both sides, 520 pairs of sting device blade tips of outer conductor active force G
Directly' horizontal component must be greater than making the first blade 100 and the second blade 200 that the power that elastic deformations depart from original track occur.And simultaneously, G
Directly' should be as far as possible little, can be by its reaction force G more to guarantee outer conductor 520
DirectlyDamage.Under the same size, G
Directly' size be that material by the first blade 100 of sting device and the second blade 200 determines, therefore, the material of the first blade 100 and the second blade 200 should be selected the less elastomeric material of modulus of elasticity, preferably, the elasticity of the first blade 100 and the second blade 200 is between the elasticity of the elasticity of the insulating sleeve 510 of cable 500 and outer conductor 520, and hardness is identical or close with the hardness of the outer conductor of cable.For example, blade material can be selected copper, copper alloy, aluminum or aluminum alloy etc.
To sum up, in the process of the insulating sleeve 510 of blade incision cable, because what select is sharp blade, blade incision insulating sleeve 510 required power f will be less, therefore the reaction force g of insulating sleeve 510 blade is directly ' also less, this has just guaranteed that blade can successfully cut insulating sleeve 510, simultaneously because the power f of incision insulating sleeve 510 is less, the control of adding for the blade minimum dimension makes, the cylindrical of the blade of blade and the outer conductor of cable 520 is close to tangent state, disc from outer conductor 520 after this just makes blade contact with outer conductor 520 with less power slips off rather than is cut brokenly, simultaneously with outer conductor 520 good electrically contacting arranged, this has just reached the purpose of design of this sting device.
As shown in Figure 9 and Figure 10, be the schematic diagram of the second execution mode of sting device of the present invention.This execution mode is the another kind of modification to above-mentioned two execution modes.The sting device of this kind execution mode, the nominal value of the distance between the blade tip of two blades add that the nominal value of external diameter that its limes superiors deviate can be equal to or slightly less than the outer conductor of described cable deducts its limit inferior deviate.Its difference is, two blades of this sting device respectively adopt the double-edged razor blade setting, namely the medial surface of the first blade 100 ' and the second blade 200 ' all is designed to have the blade face 120 ' and 220 ' of inclination.And preferably, the blade face 120 ' of the medial surface of the first blade 100 ' and the second blade 200 ' and 220 ' is all tangent with described outer conductor when blade tip touches the outer conductor 520 of described cable 500.All the other features are identical with above-mentioned two kinds of execution modes.Thus, when the sting device of this execution mode acts on the insulating sleeve 510 of cable 500, because the external diameter of insulating sleeve 510 is larger than the external diameter of outer conductor 520, therefore can be not tangent with insulating sleeve 510 with the blade face 120 ' and 220 ' of tangent the first blade 100 ' of outer conductor 520 and the second blade 200 ' medial surface, therefore, two blades can relatively easily lunge in the insulating sleeve.
Such as Figure 11, shown in Figure 12, when the insulating sleeve 510 that pierces through cable 500 when the sting device of this execution mode contacts with outer conductor 520, because the first blade 100 ' and the second blade 200 ' have the blade face 120 ' tangent with outer conductor, 220 ', when the blade tip insulation-piercing sheath 510 of the first blade 100 ' and the second blade 200 ' with after outer conductor 520 contacts, because and then the relation of tangent plane can avoid outer conductor 520, and then realize that tangent plane contacts with the direct of outer conductor 520, then, two blades 100 ', 200 ' can avoid to outer conductor 520 both sides under the effect of elastic force, thereby in realization and outer conductor 520 excellent electric contact, can not exist sting device to destroy the situation of outer conductor 520.
As shown in figure 13, be the schematic diagram that includes the cable grounding device of sting device of the present invention.As shown in the figure, this earthing device comprises for the receiving unit 10 that receives cable 500, and the grounded part 20 pivotally connected with this receiving unit 10, and grounded part 20 is used for forming with the cable 500 of this receiving unit 10 and is electrically connected.Wherein, grounded part 20 has the earthing member 21 for ground connection, and is fixed with sting device 22 of the present invention in fixture 23, and sting device 22 can adopt above-mentioned any execution mode, and is electrically connected with earthing member 21.When using this earthing device, cable 500 can be fixed in the storage tank 11.Storage tank 11 takes the shape of the letter U, and its internal diameter is more smaller than the outside diameter of cable, and utilizes the elasticity of U-shaped structure that cable 500 chuckings are fixed in the storage tank 11.Simultaneously, one end both sides of receiving unit 10 have hole 12, accordingly, one end both sides of grounded part have axle 24, be provided with chamfering on the top in hole 12 and the axle 24, and the width of the Width two hole inner faces of diaxon 24 outer faces is bigger, utilizes the U-shaped storage tank 11 of receiving unit 10 to hold yielding characteristic, axle 24 can be snapped in the hole 12 by chamfering, thereby form pivotally connected between receiving unit 10 and the grounded part 20.Behind access cable 500, take axle 24 as fulcrum, apply external force receiving unit 10 and grounded part 20 are relatively rotated, make sting device 22 thrust cable 500 and contact with outer conductor in the cable 500, thus the ground connection of realization cable.Easily understand, the position of hole 12 and axle 24 can exchange, and namely end both sides of receiving unit 10 have axle 24, and end both sides of grounded part 20 have axle 12.
In sum, the electrical grounding assembly that uses sting device of the present invention and include this sting device, thereby can change traditional insulated cable needs first sheath to be peeled off outer conductor, re-uses earthing device and contact realization usual manner electrical ground with cable outer conductor, but directly adopting sting device to puncture the mode that electrically contacts with outer conductor behind the sheath, this has greatly simplified mounting means.And, sting device of the present invention and the electrical grounding assembly that includes this sting device, can the insulating sleeve that effectively pierces through cable and with the conductor good contact in, can guarantee again outer conductor not to be punctured or damages, thereby realize the good earth of cable.
