Abstract
A taper tension coupling head is provided, characterized by that the taper tension coupling head is provided with an external extension sleeve in sleeve shape, with a front section in fork horn shape; the taper tension coupling head is provided with an internal extension shaft, with a tail section as a fixed terminal; and a middle section as a middle shaft with external screw thread; and a front section that is a cone shaft compressed by the external extension sleeve; the inner chamber in hollow column shape of the cone shaft is a cable hole; the cone shaft is provided with a grove along bus bar, and a screw thread opened at inner side thereof; the taper tension coupling head is provided with a locking nut that matches the middle shaft on the internal extension shaft in screw thread. The invention can be adopted without being configured with hydraulic equipment, which makes connection between on-site cables in a power system more convenient and faster.
Description
Technical field
The present invention relates to cable adapter, be applied in transforming plant lead-in in the electric power system of more specifically saying so, bus is connected with disconnecting link or circuit breaker, and the coupling head of cable turnover line.
Background technology
Continuing of being connected of the bus downlead that device clamp is widely used in transformer station and electric equipment, wall bushing and bus, aluminum equipment wire clamp also can be used for continuing of T-shape cable clamp downlead.
At present, the coupling head that is widely used in the transformer station has two kinds of forms usually, and a kind of is the crimp type device clamp, and another kind is the screw bolt-type wire clamp.In concrete the enforcement, the former must the worker is on-the-spot to be equipped with hydraulic test implementing, and hydraulic test is overweight, moves inconvenience, has greatly influenced operating efficiency, and jointing clamp is disposable, can not recycling; The latter needs to use 4 fastening bolts at least in connection, will guarantee also that simultaneously each bolt will remain on same angle and tighten, and keep stressed even, prevents that wire clamp from injuring cable.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, the tapered expanding coupling head that does not need to be equipped with hydraulic test in a kind of concrete use is provided, make in the electric power system between the on-site cable line and electric equipment be connected convenient, quick.
Technical solution problem of the present invention adopts following technical scheme.
The design feature of tapered expanding coupling head of the present invention is that it has:
One outer expanding sleeve is socket type, and the leading portion endoporus is horn mouth;
One internal expanding axle, rear are fixed terminal; The stage casing is to have externally threaded axis; Leading portion is the axis of cone that is pressed solidly by outer expanding sleeve, and the hollow columnar inner chamber of the axis of cone is a cable hole, and the axis of cone is along having groove on the bus;
One locking nut, with axis on the internal expanding axle with threaded engagement.
Design feature of the present invention also is:
The described axis of cone is four roads along the groove of offering on the bus, is cross distribution on the cross section of the axis of cone,
Inboard in the described axis of cone is provided with screw thread.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention makes in the electric power system connection between the on-the-spot cable convenient, quick, do not need to be equipped with hydraulic test, also can prevent the problem that can't re-use after hydraulic pressure is pressed the wire clamp direction instead, can increase work efficiency, reduce labor intensity, installation process is simpler, is not subjected to the restriction of equipment closure, arbitrarily translation-angle is installed, and can reuse.
2, the present invention has only used two locking nut, than prior art, the minimizing of locking nut quantity is more convenient for installing, and does not need to consider the fastening degree difference between each bolt, the fair problem of joint unbalance stress of having avoided a large amount of use fastening bolts to cause.
3, the present invention is provided with screw thread in the inboard of the axis of cone, can improve the pressure between the cable and the axis of cone, improves joint tensile strength.

Number in the figure: 1 internal expanding axle, 11 fixed terminals, 12 axis, 13 axis of cone, 14 grooves, 2 outer expanding sleeves, 21 endoporus, 3 locking nuts.
Below by embodiment, the present invention is further described in conjunction with the accompanying drawings.
Embodiment
Outer expanding sleeve 2 shown in Fig. 1, Fig. 2 (a) and Fig. 2 (b) is socket type, and leading portion endoporus 21 is horn mouth;
Internal expanding axle 1 shown in Fig. 1, Fig. 3 (a) and Fig. 3 (b), rear is a fixed terminal 11; The stage casing is to have externally threaded axis 12; Leading portion is the axis of cone 13 that is pressed solidly by outer expanding sleeve 2, and the hollow columnar inner chamber of the axis of cone 13 is a cable hole, and the axis of cone 13 is along having groove 14 on the bus; The axis of cone 13 in the present embodiment has four roads along the groove of offering on the bus 14, and four road notches are cross distribution on the cross section of the axis of cone 13, be provided with screw thread in the inboard of the axis of cone 13.
Locking nut 3 as shown in Figure 1 be with internal expanding axle 1 on axis 12 with threaded engagement.
In the present embodiment, have screw thread in the axis of cone 13 inboards.Exert pressure by twisting 3 pairs of outer expanding sleeves 2 of locking nut, outer expanding sleeve 2 is moved to the cable direction, outer expanding sleeve 2 is exerted pressure with the chucking cable to the axis of cone 13, and the screw thread that the axis of cone 13 inboards are offered can help to improve the pressure of cable and the axis of cone 13 inboards, improves tensile strength.
Version of the present invention is suitable for various materials, and at aluminum alloy material, the moulding of internal expanding axle 1 is earlier an aluminium bar to be milled tapering at leading portion, and mills sky with in it, leaves thread on the axis.The engagement process of each member is: outer expanding sleeve 2 is enclosed within on the internal expanding axle 1 from afterbody, subsequently internal expanding axle 1 and on two locking nuts 3, locking nut 3 is the tail end suits from the internal expanding axle, rear with the internal expanding axle flattens at last, and open two screws thereon, form fixed terminal 11, entire equipment is finished like this.
During use, to be connect in the cable hole that the cable head is inserted in internal expanding axle 1, twist locking nut 3, locking nut 3 promotes outer expanding sleeve 2 vertically, and exerts pressure diametrically to internal expanding axle 1 by outer expanding sleeve 2, and the width of groove 14 is compressed, the axis of cone 13 thereby to formed pressure by connector lug, finish wiring, by fixed terminal 11 with internal expanding axle overall fixed on required equipment, reach the purpose that wire clamp connects.
