Abstract
The utility model relates to a current connecting top for screw arbor type terminals, which is a detachable current connecting top of a screw arbor type wire connecting terminal for leading out current of electric appliances and conducting wires. The current connecting top belongs to the technical field of line appliances and is composed of a wire connecting terminal, an opened spring, a multi-flap tube, locking nuts and a connecting top body, wherein, the multi-flap tube is a circular tube whose inside and outside all have threads; the external circle of the multi-flap tube is tapered and is mutually matched with the locking nut whose internal circle is tapered; the inner thread of the multi-flap tube is mutually inosculated with the outer thread of the wire connecting terminal; the opened spring is positioned at the inner side of the front opening portion of the multi-flap tube; the multi-flap tube and the connecting top body is an integral body. The connecting top has the functions of reliable contact, no fever and no burnt damage.
Description
The utility model is dismountable current joint that the screw shaped binding post about the electrical equipment projected current is connected with lead, belongs to the technical field of line materials.
At present, the binding post of various high and low voltage electrical equipment projected currents such as transformer, sleeve pipe has screw shaped, round bar shape and perforated plate shape.Being connected between screw shaped binding post and bus row or the twisted-wire contact, normally on the plane of bus row or joint, hole, be enclosed within on the screw rod, the top and bottom, plane are respectively with a nut, fastening nut is clamped the plane, as current path, this connected mode is by big electric current the time, and often heating burns out.Reason is the external screw thread of 1. electric currents from screw rod when flowing to internal thread on the nut, only has electric current to flow through in the stressed side of ridge, and the another side is that false contact no current flows through.2. in the total length of the internal and external threads that contacts with each other, having only several pitch threads is real contact and conduction.Other screw thread is because screw thread deformation extent difference when tightening, and the contact electric conductivity is bad.3. the stop nut that install additional on upper nut in order to prevent loosening, it presses portion's nut downwards, upwards draws the screw rod terminal, causes the loose contact of screw rod and nut.4. the contact-making surface between six-sided nut and bus row or the joint is less, during logical big electric current easily heating burn out.
Goal of the invention of the present utility model just provides the current joint of a kind of convenient disassembly, contact screw rod terminal reliable, that also can not burn out under the situation of big electric current.
The current joint of screw shaped terminal of the present utility model mainly is made up of binding post (1), split ring (2), many lobes pipe (3), locking nut (4), joint body (5), lead (6).Binding post is a screw rod, and with many lobes pipe in threads engaged.Split ring is the opening spring of a circle, has tension force radially.All have the pipe of screw thread inside and outside many lobes Guan Weiyi, its cylindrical is taper, and at the direct through groove that has vertically on the tube wall of this pipe about 4, the external screw thread and the locking nut of many lobes pipe match.The endoporus of locking nut is taper and screw thread is arranged that its tapering is 1:5～1:30.The first half of joint body is a hollow body, is connected with lead, and its Lower Half and many lobes pipe are connected to become a whole.During use, binding post is in many lobes pipe and with screw thread and matches, it is outer and identical with screw thread with many lobes pipe that locking nut is positioned at many lobes pipe, split ring is positioned at the inboard at many lobes tube opening place, when locking nut is tightened downwards, because nut is taper, so many lobes pipe will inwardly clamp, internal thread on the lobe and the screw thread tight connecting on the binding post, electric current flows into many lobes pipe and joint body from the whole flank on the screw rod.
Adopt the current joint of screw shaped terminal of the present utility model, its advantage is: owing to adopt many lobes pipe to engage with screw rod, therefore the warp-wise pressure of many lobes pipe pair of wire connection terminals is very big, can prevent axial endplay and rotation effectively, have fabulous contact performance, effectively stopped under the situation of big electric current, to burn out the situation generation of joint.Very convenient when this joint uses in addition, it is also easy to dismantle.
Fig. 1 is a structural representation of the present utility model.
Embodiment of the present utility model is as follows:
The front end of binding post (1) is made bolt shape and is matched with the internal thread of many lobes pipe, the outer surface of many lobes pipe (3) is a tapered thread face, match with locking nut (4), split ring (2) is arranged in the annular groove of inboard, many lobes pipe open front place, when locking nut unclamps, split ring will be done radial expansion, and many lobes pipe is unclamped.When binding post (1) and lead (6) were identical material, joint body (5) adopted the material identical or close with lead (6) with binding post (1) to make.When binding post (1) and lead (6) are unlike material, (as copper, aluminium).Joint body (5) is made with two kinds of material welding transition that correspond respectively to binding post (1) and lead (6), prevents couple corrosion.According to the above, just can be made into the current joint of screw shaped terminal of the present utility model.
Claims (3)
1, a kind of current joint of screw shaped terminal, formed by joint body and locking device, it is characterized in that this current joint is made up of binding post (1), split ring (2), many lobes pipe (3), locking nut (4), joint body (5), lead (6), binding post (1) is in many lobes pipe (3), it is outer also all with threaded engagement that locking nut is positioned at many lobes pipe (3), split ring (2) is positioned at the inboard of many lobes pipe (3) opening part, joint body (5) is as a whole with many lobes pipe (3), and the other end of joint body (5) and lead (6) join.
2, the current joint of screw shaped terminal according to claim 1 is characterized in that the groove number of being opened on many lobes pipe (3) is about 4, and the cylindrical of many lobes pipe (3) is taper, the inside and outside screw thread that all has of its pipe.
3, the current joint of screw shaped terminal according to claim 1 is characterized in that the endoporus of locking nut (4) is taper, and screw thread is arranged that its tapering is 1:5～1:30.
