Abstract

The utility model relates to a multi-purpose conductive joint, comprising a casing tube. One end or both ends of the casing tube are provided with turnbuckle interfaces, the inner side of the casing tube is provided with an expansion head, and a hollow pressure bolt which can press the expansion head is provided; the screw bolt is matched and connected with the casing tube, the expansion head can be a cone hollow expansion head, and the upper side of the cone hollow expansion head is provided with a plurality of clearance grooves. The utility model has the advantages of convenient use, time-saving and labor-saving performance, simple manufacture and low cost, and can meet the connection need of the conductive body and the electric equipment.

Description

Use conductive contact more

(1) technical field: a kind of conductive contacts of using that the utility model relates between the copper-lead insulated wire joint in the terminal between electric wire, particularly power circuit, between the cable joint, be connected between lead and the power consumption equipment more.

(2) background technology: in existing conductor connected mode mainly be by manually around bundle, terminal board connects, the aluminium row pressure connects, connection between the line nose, welding, conduit crimping.As the method for attachment of lead and power consumption equipment, defectives such as that these methods all exist in actual use is time-consuming, effort, result of use difference, in service in energising, heating, phenomenon such as loosening are also arranged, bring potential safety hazard to equipment operation.

(3) summary of the invention: the purpose of this utility model provide a kind of easy to use, save time, laborsaving, make simple, cost is low, can satisfy conductor and power consumption equipment connection request use conductive contact more.

The utility model is many to have sleeve pipe with conductive contact, and the one or both ends of its sleeve pipe have the screw thread interface, are provided with expansion-head in the sleeve pipe, and have a hollow hold-down bolt that compresses expansion-head, and this bolt and sleeve pipe are connected.

Its expansion-head is the hollow expansion-head of cone, has several clearance grooves on it.

Its using method is that lead is passed hollow hold-down bolt and expansion-head, then they are packed in the sleeve pipe, screwed connection by hollow hold-down bolt and sleeve pipe one end, hold-down bolt makes the expansion-head of its inside evenly shrink when screwing inwards, reach the purpose that compresses lead, thereby make lead form enough conductive contact surfaces, reduced the resistance of joint.

The utility model is easy to use, time saving and energy saving, makes simply, and cost is low, can satisfy the connection request of conductor and power consumption equipment.

(4) description of drawings:

Fig. 1 can connect the conductive contact schematic diagrames of using of lead more for the two sides.

Fig. 2 uses the conductive contact schematic diagram for wire more.

Fig. 3 is the expansion-head schematic diagram.

Among the figure: 1-sleeve pipe, the hollow hold-down bolt of 2-, 3-expansion-head, 4-lead, 5-wire sleeve pipe, 6-clearance groove.

(5) embodiment:

Example 1, referring to Fig. 1 Fig. 3, with the copper of different size, aluminium, roundwood as the processing raw material, make sleeve pipe 1 through technologies such as moulding, car silk, borings, sleeve pipe 1 two ends have the screw thread interface, be provided with two expansion-head 3 in the sleeve pipe 1, and have the hollow hold-down bolt 2 that compresses expansion-head 3, bolt 2 is connected with sleeve pipe 1; Its expansion-head 3 is that cone is hollow, has 3-4 clearance groove 6 on it.As long as being put into sleeve pipe 1 by bolt 2 and expansion-head 3, lead 4 screws bolt 2.

Example 2, referring to Fig. 2, the copper of different size, aluminium, roundwood as the processing raw material, are made wire sleeve pipe 5 through technologies such as moulding, car silk, borings, and the one end has the screw thread interface, the rear end of other end sealing is the stay thimble of wire, be provided with an expansion-head 3 in the sleeve pipe 5, and have the hollow hold-down bolt 2 that compresses expansion-head 3, bolt 2 is connected with sleeve pipe 1, only need lead 4 is put into sleeve pipe 5 by bolt 2 and expansion-head 3, screw bolt 2 and get final product.

Claims

1. using conductive contact one kind more, have sleeve pipe, it is characterized in that the one or both ends of sleeve pipe have the screw thread interface, be provided with expansion-head in the sleeve pipe, and have a hollow hold-down bolt that compresses expansion-head, this bolt and sleeve pipe are connected.

2. according to claim 1ly a kind ofly use conductive contact, it is characterized in that: expansion-head is a conulite, has several clearance grooves on it more.
