Abstract

The utility model relates to an axial piercing wire clip for twin insulating cables, consisting of upper tooth boxes and lower tooth boxes that can be engaged with each other; the two tooth boxes are fixed and pressed tightly by a screw rod; radial racks are embedded at the bottom of the perforating holes in the two tooth boxes in radial direction; three or four teeth on the radial rack form a semi-circle; the tooth head points at the circle center; the axial piercing wire clip comprises two upper tooth boxes and two lower tooth boxes; the upper tooth box have two independent structures; the lower tooth boxes have an integrated structure; and axial racks are embedded at the bottom of the perforating holes of the two tooth boxes in axial direction of a wire slot. When in use, two cables with the insulating layers are arranged in the perforating holes; and the screw rod is screwed down so as to press the axial racks and the radial racks to pierce the insulating layers of the cables and contact with cable conductors so that the two cables with the insulating layers can be connected with each other. By adopting the axial piercing wire clip, the conducting wires of different diameters can be contacted with each other reliably; the upper tooth box and the lower tooth box adopt the twin structures so that one conducting wire can be divided into two conducting wires with different diameters; and the tooth space is larger and the teeth on the rack in the same perforating hole are crossed so as to lighten the harm of the tooth on the insulating layer of the cable, thus ensuring the bearing capability of the insulating layer.

Description

The axial penetrating cable clamp of duplex insulated cable
Technical field
The utility model patent relates to the wire clamp that a kind of insulated cable connects.
Background technology
The existing wire clamp that is used for the cable connection, constitute by nibbling complete upper and lower tooth box 1,2 up and down, the bottom transverse of the through wires hole in the two tooth boxes is embedded with tooth bar 3, be fixed and clamped with screw rod 4 between two tooth boxes, because tooth bar is laterally to embed, the number of teeth amount that is embedded with on the tooth bar is limited, because tooth is few, the area that contacts with cable is little, and contact resistance is bigger, also easily cable sheath is caused the damage of blocking property.
The applicant's the patent No. is ZL200420018203.5, and the utility model patent that name is called " the axial penetrating cable clamp of cable " has solved the problems referred to above, but also has following problem:
1, because each specifications and models penetrating cable clamp is wanted the corresponding certain limit line footpath lead that connects, and the radian of gear piece is a certain value, when the line of lead footpath bigger, its radian is during greater than the radian of gear piece, the gear piece only tooth on circular arc both sides has preferably with lead and contacts, and the tooth at circular arc middle part is connected the bad contact resistance increase that causes with lead, equally, when the line of lead footpath less, its radian is during less than the radian of gear piece, the gear piece only tooth at circular arc middle part has better the contact with lead, and the tooth on circular arc both sides contacts the bad contact resistance increase that also will cause with lead;
2, during engineering is used, when needs with a wire clamp when a lead is told two not collinear footpath leads simultaneously and is used for different load, it does not possess this function.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aim to provide and a kind ofly can increase contact area, minimizing to cable skin damage, again can reduce because of the gear piece radian not corresponding with not collinear footpath lead radian, and cause contact resistance to increase, can satisfy the axial penetrating cable clamp of duplex insulated cable that utilizes a wire clamp to tell two not collinear footpath leads from a lead simultaneously.
The implementation of the utility model purpose is, the axial penetrating cable clamp of duplex insulated cable, constitute by nibbling complete upper and lower tooth box, be fixed and clamped with screw rod between two tooth boxes, the bottom of the through wires hole in the two tooth boxes radially is embedded with radially tooth bar, radially 3 on tooth bar or 4 rooted teeth constitute a semicircle, the tooth head points to the center of circle, and upper and lower tooth box is respectively two, and last tooth box is two absolute construction, the lower tooth box is structure as a whole, and the bottom fluted shaft along the line of the through wires hole in the two tooth boxes is to being embedded with axial tooth bar.
During use, place through wires hole without the cable of peelling off crust with two, tighten the compressing of two screw rods axially and radially tooth bar pierce through cable sheath and contact with cable conductor, and tooth bar is mutual conducting, thereby can make two to be with the cable of crusts to interconnect.Owing to go up the tooth box and separate for two, thereby can on main traverse line, insert two not offsets in collinear footpath simultaneously.
Thereby the utility model all can reliably contact not collinear footpath lead and reduce contact resistance; Last lower tooth box adopts the duplex structure, can tell two not leads in collinear footpath from a lead; Tooth pitch is bigger, and the tooth on the tooth bar of same through wires hole is staggered, has alleviated the injury of tooth to cable sheath greatly, has guaranteed the effect of crust in the cable load.

Embodiment
The utility model is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1-4, the utility model constitutes by nibbling complete upper and lower tooth box 1,2, and wherein two last tooth boxes 1 are two absolute construction, and two lower tooth boxes 2 are structure as a whole.Be fixed and clamped with two screw rods 4 between two tooth boxes.Tooth on the same through wires hole tooth bar is interlaced.Owing to go up the tooth box and separate for two, thereby can on main traverse line 5, insert two not the offset A8 and the lead B9 in collinear footpath simultaneously.
Radially be embedded with the bottom fluted shaft along the line of the through wires hole in tooth bar 3, the two tooth boxes radially to being embedded with axial tooth bar 7 with reference to the bottom of the through wires hole in Fig. 5-8, two tooth box.Radially 3 or 4 rooted teeth on the tooth bar 3 constitute a semicircle, and the tooth head points to the center of circle.
The direction axially-aligned that axial tooth bar of the present utility model is walked along cable, increased the number of teeth on the one hand, increased the contact area of tooth bar and cable conductor, axial tooth and cable radian are irrelevant on the other hand, have reduced contact resistance thereby all can reliably contact not collinear footpath lead.Radially tooth bar 3 can suitably increase tooth pitch with axially tooth bar 7 is vertical mutually, and makes the tooth on the tooth bar of same through wires hole staggered, has alleviated the injury of tooth to cable sheath greatly, has guaranteed the effect of crust in the cable load.
During use, place through wires hole without the cable of peelling off crust with two, tighten two screw rods 4 compressing axially and radially tooth bar pierce through cable sheath 5 and contact with cable 6 conductors, and tooth bar is mutual conducting, thereby can make two to be with the cable of crusts to interconnect.
