The wire holder mainly comprises a wire holder shell, a screw rod, a driving nut, a connecting rod and a linkage shaft. When the screw rod is rotated forward, the driving screw cap matched with the bottom of the screw rod rises according to the mutual meshing force of the threads, the hinged linkage shaft parts of the two connecting rods extrude towards the wiring area, the electric wire is clamped between the shell and the linkage shaft, and the functions of electric wire installation and connection conduction are completed. Conversely, the clamped wire is released from the clamped condition. In the whole operation that the wire holder is connected with the wire, the clamping or unclamping action of the internal mechanism of the wire holder on the wire is finished in the wire holder, and the appearance size of the wire holder is not changed.

Description

Triangle inflation formula electrical connection seat

Technical Field

The invention relates to an accessory for electrical connection, in particular to a wire holder for connection between a switch, a socket and an electric wire.

Background

In a conventional wire holder, after an electric wire penetrates into a wiring area of the wire holder, a force is applied in a direction perpendicular to the electric wire, so that a clamping screw or a clamping plate continuously occupies the space of the wiring area, and the electric wire penetrating into the wiring area is clamped and reliably connected and conducted. If the space of the force application direction is limited, the operation difficulty of wiring of the wire holder is increased.

Disclosure of Invention

The purpose of the invention is as follows: the force application part of the wire holder is changed from the vertical direction of the wire to the same direction of the wire. That is, after the electric wire is inserted into the wire connection area of the wire holder, the force application screw is operated in the same direction as the insertion of the electric wire, so that the internal mechanism of the wire holder is operated to clamp the electric wire inserted into the wire holder.

The technical scheme is as follows: a full-length force application screw penetrates into the wire holder, and a nut matched with the screw thread is assembled at the bottom of the screw and ascends or descends under the rotation of the screw in the positive direction or the negative direction. The upper parts of the nut and the wire holder shell, which are close to the screw rod, are used as two hinge points, two connecting rods are installed, and the other end parts of the connecting rods are hinged through a linkage shaft. Thus, the sections from the screw rod to the screw cap are taken as the bottom edges, and the two connecting rods are taken as the waist edges, so that an isosceles triangle is formed. The length of the waist edge is not constant, the screw rod is rotated forward, so that the screw cap rises, namely, the length of the bottom edge of the isosceles triangle is reduced, the height of the isosceles triangle is increased, and the isosceles triangle occupies the space of a wiring area of the wiring seat, so that the electric wire inserted into the wiring seat is clamped.

Has the advantages that: when the force application direction space of the vertical electric wire of the existing wire holder is limited, the force application operation and the direction of the electric wire penetrating into the wire holder are the same through the improvement, the operation difficulty of the electric wire access is reduced, and the construction hidden danger of poor contact is reduced. Meanwhile, in the whole operation of connecting the wire holder to the wire, the action of the clamping mechanism is completed in the wire holder, the appearance size of the wire holder is not changed, and the wire holder is very suitable for installation in a narrow space area.

Detailed Description

Example 1: wire holder 1 assembly example.

The shell 15 of the wire holder 1 is divided into two areas, one is a mounting area of a driving mechanism, the area is sealed up and down, a screw 12 penetrating through the upper and lower seals is mounted in the area, a force application screw 11 connected with the screw 12 into a whole is arranged at the upper end of the screw 12 and on the outer side of the shell 15, and a driving nut 13 matched with the screw 12 in a threaded mode is mounted at the bottom of the screw 12 and on the inner side of the shell 15. The drive nut 13 is raised or lowered by the force of the screw thread as the screw 12 is rotated in the forward direction or the reverse direction. Two connecting rods 14 are arranged by taking the driving nut 13 and the upper part of the shell 15 of the wire holder 1 close to the screw 12 as two hinge points, and the other ends of the connecting rods are hinged by a linkage shaft 16. The other is a wiring area into which the electric wires 3 to be connected are passed to wait for connection.

Example 2: the wires are threaded from the bottom or front face to the wire connection area of the wire holder 1.

The part of the wire 3 to be connected, which is removed the insulating layer, penetrates into the wiring area from the bottom surface or the front surface of the wire holder 1, the force application screw 11 is rotated from the positive direction by a special tool, the screw rod 12 is driven to rotate positively together, the driving screw cap 13 matched with the bottom of the screw rod 12 is lifted, the parts of the hinged linkage shafts 16 of the two connecting rods 14 are extruded towards the parts of the penetrated wire 3, the wire 3 is tightly clamped between the shell 15 and the linkage shafts 16, and the functions of installation and connection conduction of the wire 3 are completed.

Example 3: the wires are pressed into the terminal area of the terminal holder 1 from the side.

This embodiment is directed to a wire holder 1 having an opening 2 in the side of the housing 15.

The part of the shell 15 with the side opening 2 is penetrated into the wiring area, the part of the wire 3 to be connected, which is provided with the insulation layer, is rotated from the positive direction by a special tool to drive the screw rod 12 to rotate positively, so that the driving screw cap 13 matched with the bottom of the screw rod 12 is lifted, the hinged linkage shafts 16 of the two connecting rods 14 extrude the part of the penetrated wire 3, the wire 3 is tightly clamped between the shell 15 and the linkage shafts 16, and the functions of installation, connection and conduction of the wire 3 are completed.

Example 4: the electric wire 3 is detached from the wire holder 1.

The force application screw 11 is rotated in the forward direction, and the internal mechanism of the wire holder 1 acts to tightly clamp the wire 3. Conversely, the force application screw 11 is rotated reversely, the screw 12 drives the driving nut 13 to move downwards, so that the hinged linking shaft 16 of the two connecting rods 14 moves towards the screw 12, the clamped electric wire 3 is released, and the electric wire 3 can be moved out of the wire holder 1.
