Abstract

The utility model relates to a wire connection device, which mainly relates to a holder used for the pressing connection of a wire connection base and wires. The utility model is characterized in that a wire pressing piece in which a small diameter margin of the back segment is movably inserted a through hole of a fastening piece is arranged in a screw hole arranged on one side of the wire connecting base, the front end of the outer margin of the wire pressing piece is a flange which has a large diameter, the back segment of the press line piece is a hollow sleeve barrel which has a small diameter margin, and a platform shoulder arranged between the flange which has a large diameter and the small diameter margin is abutted on the front end of the fastening piece. Accordingly, a wire core can not be broken because of friction.

Description

The clamper of wire connecting base

The utility model relates to a kind of wire connecting device, mainly refers to the clamper that wire connecting base is connected with compressing of electric wire.

At present, traditional wire connecting base, as Fig. 3, shown in 4, system inserts electric wire 7 in the urgent line spare 5 of a hollow tubular, outside the electric wire core 71 that the electric wire front end exposes passes urgent line spare 5, again the electric wire line stamen 71 that exposes is bent to rest on from inside to outside and compel around the set pressure edge 51 in line spare 5 tops, borrow and compel the set screw thread in the outside, line spare 5 stage casings, can be screwed in a bottom and be provided with on the electric-conductor 6 of screw 61 compeling line spare 5, but because of pressing edge 51 and urgent line spare 5 is one-body molded, when so line spare 5 is compeled in rotation, can make and press edge 51 also to rotate simultaneously, this moment, curved leaning against pressed intermarginal electric wire line stamen 71 in edge 51 and screw 61 bottoms, will thereby press edge 51 and screw 61 inner edges constantly to rub, the result easily causes 71 loose contacts of electric wire line stamen, even the electric wire fracture.

In view of this, the purpose of this utility model provides a kind of clamper of wire connecting base, can keep electric wire line stamen to press and be clipped between the thread pressuring article flange and wire connecting base that does not rotate.

The purpose of this utility model is achieved in that a kind of clamper of wire connecting base comprises forcing piece, wire connecting base, it is characterized in that: in wire connecting base one side screw, be provided with the movable thread pressuring article that inserts in the forcing piece through hole of its back segment path edge, this thread pressuring article is that the flange in big footpath of outer rim leading portion and back segment are that the intermarginal shoulder of the flange in the hollow sleeve of path edge and big footpath and path is resisted against and chases after tight part front end, and the external screw thread on the forcing piece matches with the screw of wire connecting base.

Owing to adopting such scheme: the unlikely friction of electric wire line stamen ruptured.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments exploded view.

Fig. 2 the utility model exemplary embodiments cross-sectional schematic.

The exploded view of the known electric wire connector of Fig. 3.

The cross-sectional schematic of the known electric wire connector of Fig. 4.

Among the figure: 1 thread pressuring article, 11 flanges, 2 forcing pieces, 3 wire connecting bases, 31 screws, 4 electric wires, 41 electric wire line stamens, 5 are compeled line spare, 51 and are pressed edge, 6 electric-conductors, 61 screws, 7 electric wires, 71 electric wire line stamens.

As shown in Figure 1, 2, forcing piece 2 has interior step through-hole in the middle of being, outer rim has externally threaded screwed pipe; Thread pressuring article 1 is that the outer rim leading portion is the flange 11 of big footpath arc-shaped surface, and back segment is the hollow sleeve of path edge (step); Wire connecting base 3 one sides are provided with the screw 31 that matches with forcing piece 2 external screw threads; The shoulder that thread pressuring article 1 inserts in the front aperture of forcing piece 2 with its path edge and flange 11 and path are intermarginal leans at forcing piece 2 front ends, and forcing piece 2 screws in the screw 31 of wire connecting base 3 with it; Electric wire 4 front ends are removed outer plastic cement skin, and expose one section electric wire line stamen 41, and insert from forcing piece 2 rear ports, make the outer plastic cement skin termination of its electric wire 4 lean end just at thread pressuring article 1, and make on outwardly-bent flange 11 surfaces that lean against thread pressuring article 1 of electric wire line stamen 41, screw (rotation) forcing piece 2, this moment, thread pressuring article 1 was not with forcing piece 2 rotations, the electric wire line stamen 41 that exposes is fixed to press and is clipped between flange 11 and the wire connecting tube 3, therefore, the electric wire line stamen 41 that exposes is not rubbed and fracture occurred.

Claims

1, a kind of clamper of wire connecting base comprises forcing piece (2), wire connecting base (3), it is characterized in that: in wire connecting base (3) one side screws (31), be provided with the movable thread pressuring article (1) that inserts in forcing piece (2) through hole of its back segment path edge, this thread pressuring article (1) is that the flange (11) in the big footpath of outer rim leading portion and back segment are that the intermarginal shoulder of flange (11) and path in the hollow sleeve of path edge and big footpath is resisted against forcing piece (2) front end, and the external screw thread on the forcing piece (2) matches with the screw (31) of wire connecting base (3).
