Detailed Description
The following provides a more detailed description of the present invention, with reference to the accompanying drawings.
The first embodiment is as follows:
a precession splitting binding clip, as shown in figure 1, this embodiment is used for connecting branch lines at the same time in four wires with insulating skins 7, as shown in figure 2, this embodiment includes an upper clamping block 2, a lower clamping block 1 and splitting screws 4, a threading hole 9 for accommodating the wires is formed when the upper clamping block 2 and the lower clamping block 1 are jointed, and the wires are basically fixed in the threading hole 9. Five fastening screw 3 have been used to this embodiment, go up clamp splice 2 processing and have five through-holes that are used for passing fastening screw 3, lower clamp splice 1 processing has the blind hole that quantity and position correspond with the through-hole, and the blind hole processing has the internal thread, and fastening screw 3 passes behind the clamp splice 2 with 1 threaded connection of clamp splice down, has placed elastic gasket 8 between fastening screw 3 and the last clamp splice 2.
Four threaded holes for penetrating through the skin breaking screws 4 are processed in the positions, corresponding to the threading holes 9, of the upper clamping block 2, the skin breaking screws 4 are screwed into the upper clamping block 2 along the radial direction of the threading holes, as shown in fig. 3 and 4, the tail portions 404 of the skin breaking screws 4 are flat end surfaces, straight grooves are processed in the tail portions 404 of the skin breaking screws 4, along with the screwing-in of the skin breaking screws 4, the tail portions 404 of the skin breaking screws 4 break the wire insulation skins 7 and are in contact with the wire cores 6, the skin breaking screws 4 are conductors, and the skin breaking screws 4 are connected with branch lines after being in contact with the wire cores 6. The protruding tail 404 of the peeling screw 4 can improve the peeling effect, but can lead to the final contact surface with the conductor core being greatly reduced, and the concave tail 404 of the peeling screw 4 can improve the area of the contact surface with the conductor core, but can lead to the peeling difficulty, and the peeling of the insulating coating 7 can not be completed.
The broken principle of this embodiment is that broken skin screw 4 twists makes, at first causes the extrusion to insulating skin 7, and the groove of opening simultaneously makes during the insulating skin 7 snap-in groove of part, broken skin screw 4 continues to rotate, and insulating skin 7 in the snap-in groove forms along with the rotation: (1) the insulation skin 7 clamped in the groove tears the insulation skin 7 around to form a crevasse, (2) the smooth tail 404 end surface of the skin breaking screw 4 pushes the insulation skin 7 with the crevasse to make the insulation skin deform around, so that the crevasse is enlarged, and finally the insulation skin 7 with less scraps and large crevasse is formed. Broken skin screw 4 and wire core 6 butt back carry out a small amount of precession again, make broken skin screw 4 afterbody 404 and wire core 6 all take place a small amount of deformations, make the line contact enlarge into the face contact, promote the conducting capacity of binding clip by a wide margin. The hardness of the head 401 of the skin breaking screw 4 is less than that of the wire core 6. The tail 404 of the skin breaking screw 4 is made of softer material than the wire core 6, and the deformation occurs more at the tail 404 of the skin breaking screw 4. The tail 404 of the skin breaking screw 4 is mainly a flat surface, so that the deformation of the wire core 6 is the integral flattening, the surface layer of the wire core 6 cannot be cut and cut, and a small amount of deformation has little influence on the conductivity of the metal conductor under the condition that the surface layer of the metal conductor is not cut and broken. The pushed-away insulating skin 7 is gathered around the tail 404 of the skin breaking screw 4 to form an enclosure for the tail 404 of the skin breaking screw 4, the elasticity of the insulating skin 7 extrudes the tail 404 of the skin breaking screw 4, and the insulation of the joint is improved.
The slotting direction of the straight groove of the skin breaking screw 4 is adjusted to ensure that the extending direction of the straight groove of the tail 404 of the skin breaking screw 4 is basically parallel to the extending direction of the threading hole 9 when the tail 404 of the skin breaking screw 4 is firstly contacted with the insulating skin 7 in the screwing-in process of the skin breaking screw 4. More insulating skins 7 can be clamped in, and the skin breaking effect is improved. Through the preassembly technology, the skin breaking screw 4 is screwed into a preset position in advance, and when the skin breaking screw is used, the screwing-in number of turns is fixed, so that the screwing-in time of the skin breaking screw 4 can be determined. It is also possible to determine when to stop the threading of the skin breaking screw 4 by means of a wrench or screwdriver with a torque indication or a constant torque.
The thread pitch of the skin breaking screw 4 is slightly smaller than the thickness of the insulating skin 7, and when the skin breaking screw 4 is screwed in, the extending direction of the straight groove at the tail part 404 of the skin breaking screw 4 is basically vertical to the extending direction of the threading hole 9. The contact area between the tail part 404 of the skin breaking screw 4 and the lead wire core 6 can be increased. After the skin breaking screw 4 rotates for one circle, the straight groove is basically parallel to the extending direction of the wire core 6, the rotating skin breaking screw 4 can scrape the wire core 6, but under the preferred scheme, a small amount of insulation skin 7 still exists between the straight groove and the wire core, the rotating skin breaking screw 4 continues to rotate at the moment, the straight groove direction staggers the wire core 6 direction, and the straight groove and the wire core are contacted and continue to generate extrusion at the moment, and the scraping to the wire is minimum.
The beneficial technical effects of this embodiment are: the contact area of the jointing clamp and the conductor core 6 is increased, the conductivity of the jointing clamp is improved, the damage to the surface layer of the conductor core 6 is reduced, and the influence on the conductivity of the conductor core 6 is small.
Example two:
in the embodiment, on the basis of the first embodiment, the structure of the skin breaking screw 4 is further limited, so that the conductive reliability of the connection of the rest branch lines is improved. As shown in fig. 5, in this embodiment, a wire connection portion 402 with a smooth outer surface is formed in the middle of the skin breaking screw 4, and a thread portion 403 of the skin breaking screw 4 is in threaded connection with the upper clamping block 2, so as to facilitate leading out of a branch line. The wire connecting part 402 of the smooth outer surface processed in the middle of the skin breaking screw 4 is abutted to the conductive block 10, the conductive block 10 is embedded on the upper clamping block 2, and the conductive block 10 penetrates out of the upper clamping block 2. The connection reliability of the branch line and the skin breaking screw 4 is improved, and the conductivity is further improved. The wire connecting portion 402 may be formed on the head 401 of the binding screw, and connected to the wire connecting portion 402 by the lead 5.
Comparative example:
in this comparative example, the tail 404 of the skin breaking screw 4 was compared with four embodiments: namely a, a straight groove, b, a cross groove 4-2, c, two blades 4-1 and d, four blades 4-3. As shown in fig. 6, the two blades 4-1 are two end milling blades machined at the tail 404 of the skin breaking screw 4, and the four blades 4-3 are four end milling blades machined at the tail 404 of the skin breaking screw 4. The straight groove or the cross groove 4-2 is easy to process at the tail part 404 of the skin breaking screw 4, and the shape of the groove can be better ensured.
As can be seen from fig. 6:
(1) the straight grooves eventually have the largest area of the skin broken, i.e. the best connection contact can be made.
(2) The end face of the tail part 404 of the straight-groove skin breaking screw 4 has the largest flat area, and the contact area with the wire core 6 is also the largest.
(3) The straight groove has almost no cutting effect on the insulating skin 7, no cutting trace is seen on the broken opening of the insulating skin 7, the cross groove 4-2 has a little cutting trace, and the two edges 4-1 and the four edges 4-3 have obvious cutting effect on the insulating skin 7. The straight flutes produce minimal fine swarf. The 7 pieces of the larger piece of insulation skin that drop in the picture are originally inlaid in the straight groove and drop when taking out to take a picture.
As can be seen from fig. 7:
(4) the straight grooves have an influence on the wire core 6 mainly by extrusion deformation, so that the wire core 6 is flattened and the surface layer of the wire core 6 is not damaged basically. The cross groove 4-2 scrapes the surface layer of the conductor core 6 to form a polished area. Two edges 4-1 have scratches and a small amount of cutting, while four edges 4-3 obviously cut the wire core 6 to form irregular bulges and grooves, so that the electric conduction capability of the wire core 6 is damaged most. The damage of the straight groove and the two blades 4-1 to the wire core 6 is respectively less than the damage of the cross groove 4-2 and the four blades 4-3 to the wire core 6.
With reference to fig. 6 and 7, the effect of the skin breaking screw 4 on the insulation skin 7 is not a cutting effect, but a tearing and squeezing effect. In this comparative example, the scale of the pierce screw 4 used was M6x1, i.e., the pitch was 1mm, and the thickness of the insulating sheath 7 of the wire was 1.2mm, which was slightly larger than the pitch of the pierce screw 4. That is, the tail 404 of the skin breaking screw 4 rotates only a little more than 1 turn from just contacting the insulation skin 7 to finishing the skin breaking, and advances 1mm during 1 turn, so that two blades 4-1 and four blades 4-3 are not in time to finish the cutting process due to too few turns, and thus the skin breaking area is smaller than that of a straight groove as shown in fig. 6.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
