Abstract
The utility model relates to an electric terminal with a screw. The utility model is characterized in that a connecting body which is provided with a deformed groove is provided with one or a plurality of conical surfaces; an outer cone of the connecting body is deformed by the oppression of the inner conical surface of a fastening cap so as to clamp a cable which is inserted in a grooved cone; the other end of an electric conductive cone is additionally provided with a section of the screw which is used for fastening. The electric terminal with a screw of the utility model can be used in electric equipment and can get rid of a welding procedure in the prior art. In addition, the electric terminal with a screw can also be used for connecting a large-sized transformer and a high-tension bushing joint with cables, or connecting a perforated conductive strip of a large voltaic alternating current contactor, an automatic air switch, etc. with cables.
Description
The utility model is a kind of electrical connector, belongs to the accessory product in the electric equipment.
In electric equipment, be extensive use of the conductive pole of band screw or the busbar of band screw and connect other electric conductor.For example, the single-phase No-load changer switch in the high-power transformer, contact stud are exactly a kind of conductive pole with screw.Conductive pole is connected with transformer voltage regulation coil lead-in wire.When connecting, a kind of cable joint of conductive pole and leader cable intermediate configurations with screw rod, it does not have a hole for the leader cable insertion with an end of screw rod, adopts phosphor-copper oxygen welding welding procedure then, lead-in wire is welded with joint, and the transition joint after welding is again in the conductive pole of precession band screw.
Because this transition joint is connected with leader cable, need high-temperature soldering, want scaling loss or fusing part cable copper stranded conductor inevitably, the also lead wire insulation of wanting scaling loss or carbonization to bandage inevitably, welding later cable joint must send to big and heavy copper cable and ward off tin, increased labour intensity, in addition, because leader cable is the red copper material, if joint adopts the more cheap brass material of price, when implementing the oxygen welding operation, the conductor welding quality of unlike material also can not get reliable assurance, therefore, this defines this joint again and must adopt the more expensive red copper material of price.
The purpose of this utility model provides a kind of can the use widely on the electric conductor of being with screw in electric equipment, and can connect the electrical connector of lead-in wire safely, reliably, easily.
The electrical connector of the said band screw rod of the utility model is made up of connector 1 and fastening cap 2 two parts.End at said connector 1, have for the hole 3 of settling cable, on this periphery for the connector 1 of settling cable one end, be provided with the distortion groove 4 more than two or two, in the excircle part of its connector 1, also be provided with the screw thread 5 that matches with fastening cap 2 and more than one or one with the conical surface that matches 6 of fastening cap 2; The other end at connector 1 is provided with the screw rod 7 that is connected with electric equipment and supplies fastening device 8.Centre at said fastening cap 2, the through hole 9 that has current supply cable to pass, the internal thread 10 and one or more and the inner conical surface 11 that connector 1 conical surface 6 matches that match with screw thread 5 on the connector 1 are arranged in the through hole 9, the fastening device 8 ' of confession is also arranged on the neighboring of fastening cap 2.
According to the said electrical connector of the utility model, can also in the hole 3 that current supply cable is settled, shape of threads or circular tooth 12 be set.
Root at distortion groove 4 can be the slick and sly form of arcuation, to increase the intensity of distortion cone self.
The occupation mode and the principle of electrical connector described in the utility model are as follows: the screw rod on the connector can be installed or is screwed onto in the inner nut of conductive pole of electric equipment (as switch), cable is inserted in the hole on the connector, fastening cap is screwed onto has on the screw thread of distortion groove cone, the inner conical surface in the dependence fastening cap and the interaction of the conical surface on the connector, the distortion of compressing fluting cone, thus clamp lead-in wire or the cable that inserts.
The said electrical connector of the utility model has been compared following advantage with cable joint of the prior art:
1, do not need high-temperature soldering, when having saved welding material and Welder;
2, the zinc-plated operation of joint need not carried out after high-temperature soldering, has alleviated labour intensity;
3, joint can adopt that price is cheap, the better brass material of mechanical strength;
4, demolition, installation are simple, convenient.
Accompanying drawing 1: the electrical connector of band screw rod;
A) connector; B) fastening cap;
Accompanying drawing 2: have N(N=2,3 ...) the connector schematic diagram of the individual conical surface;
Accompanying drawing 3: the version schematic diagram that tooth is arranged in the hole of connector.
Further specify formation of the present utility model below in conjunction with drawings and Examples:
Accompanying drawing 1 is for having only the electrical connector of a conical surface.On the periphery of connector 1 for the arrangement cut cable, have three or four distortion grooves 4, the other end at connector 1, be the screw rod 7 that is connected with electric equipment, at the root of its screw rod 7 is that the fastening device 8 ' of confession on fastening device 8 fastening caps 2 of the confession of six square nut forms also is six square nut shapes, the through hole 9 that has current supply cable to pass in the centre of fastening cap 2, and internal thread 10 that matches with screw thread 5 on the connector 1 and the inner conical surface 11 that matches with the conical surface 6.
Accompanying drawing 2 is the schematic diagram with connector of two and two the above conical surfaces.With accompanying drawing 1 different place be, connector 1 corresponding to the circumferential periphery of settling cable on, be provided with two or more conical surfaces 6, at this moment in fastening cap 2, also answer the two or more conical surfaces that match with it 11 of relative set.This embodiment can provide bigger clamping force.
The embodiment that accompanying drawing 3 provides, processing is provided with shape of threads or circular tooth 12 in the hole 3 of settling cable, so that bigger clamping force to be provided.This structure can be used among any embodiment.
The fastening device of said confession in the utility model can be that the nut structure form on plane is processed on all directions, six sides, four directions or two sides, its objective is in order to make the spanner can be to its application of force, so and not only be confined to the above-mentioned scheme that has provided.The fastening device of said confession all is suitable for for connector 1 and fastening cap 2, and can adopt different fastening apparatus structure forms to connector with fastening cap respectively in same set of electrical connector.
