Description

Wire connector

Technical Field

The utility model relates to the technical field of wire connection, in particular to a wire connector.

Background

The electrical fire of buildings all year round is mostly caused by the aging of wire joints. Although the reality is very severe, it still fails to attract the attention of most people. In addition, the domestic architectural decoration industry neglects the process due to long-term attention to marketing, so that the electric wire connection process cannot be upgraded, and the black tape, the wire pressing cap and the wiring terminal are generally used.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the wire connector which is safe and reliable, has a quick installation process and can completely replace the traditional soldering process.

The technical scheme includes that the wire connector is characterized in that a wire is in contact with a connecting sheet, a shell is arranged outside the wire and the connecting sheet, the connecting sheet comprises a pure copper contact connecting sheet and a thread type wire connecting sheet, the pure copper contact connecting sheet is of a V-shaped structure, the bottom surface of the pure copper contact connecting sheet is fixed in the shell, the upper surface of the pure copper contact connecting sheet is in contact with the wire, the thread type wire connecting sheet is of a tubular structure with internal threads, the diameters of openings at two ends of the tubular structure with the internal threads are different, the diameter of a smaller opening end is larger than the total diameter of the wire, and the thread type wire connecting sheet is made of a metal material such as copper or aluminum.

The utility model has the beneficial effects that: 1) this wire connector safe and reliable, 2) high-efficient: because the device can be operated completely by hands without special tools, the installation process is quick, the time consumption of each electrical connection is only 10s on average, 1/30 of the traditional soldering process is reduced, and labor and installation cost are saved. 3) The lead insulation layer is not affected by welding high temperature, the danger of high-lift melting tin soldering operation is avoided, the consistency of joint quality is good, and the environment pollution of a working place caused by welding smoke is avoided.

Detailed Description

The utility model is further described with reference to the attached drawings, the conductor connector of the utility model is suitable for the construction electric thin conductor (6 mm) with rated voltage of alternating current 1kV and below and direct current 1.5kV and below²And copper wire below). And selecting the correct type of the wire connector according to the sectional area, the number and the hardness of the connected wires.

1) The screwless conductor connector includes a universal type and a push wire type.

Applicable wire: single hard wire 0.08-2.5mm²1.50-2.5mm multi-strand hard wire²0.08-4mm multi-strand flexible conductor²And the length of the wire stripping is 12 mm.

The construction method comprises the following steps: and stripping an electric wire insulating layer according to the length, pulling up a pull rod or a push rod of the wire connector, pushing the electric wire, crimping the connector, and arranging the electric wires of the junction box according to the reserved length of the electric wire. As shown in fig. 3.

2) A twist-on wire connector.

The application is as follows: the wire connector is used for wiring of various electrical products, lamp decorations, machinery, household wiring engineering and the like, is safe, convenient and quick to use, is low in cost, and is suitable for being widely used in large batches.

The use method comprises the following steps: several wires are stripped of insulating layer and twisted together and inserted into the metal tube of the product, and then the wire pressing tool pliers are used for pressing the corresponding parts, so that the wires can be well conducted

The material is as follows: the shell is made of high-grade nylon 66 engineering plastic, and the inner metal tube is divided into copper and aluminum.

Use of: a. the wire is wound tightly, the wire is required to be put in place in the connector, and the wire is prevented from shaking up and down, left and right in the wire pressing cap as far as possible, so that poor contact of the wire after pressing is finished is prevented.

b. When the connector is pressed properly by using the crimping pliers, a proper crimping opening is selected, and the crimping is not tight due to overlarge crimping; overtightening can crush the wire and the connector and can also damage the crimping pliers.

Depending on the style of connector, different crimping ports may be selected, as shown in FIG. 4.
