Description

Technical field:

[0001] The utility model relates to the technical field of electric wire installation, in particular to a fast-installed and stable assembly structure of electric wires and quick-connect plugs. Background technology:

[0002] Wires are wires that transmit electrical energy. Wires include at least a conductor located in the center and an insulating sheath disposed around the conductor, wherein the conductor can be made of different materials such as copper and aluminum.

[0003] Among them, copper wire electrical wire is a wire that uses copper wire with good conductivity as the conductor. Among them, copper is a metal with high thermal conductivity and electrical conductivity, and can conduct electric current quickly.

[0004] In particular, wires that use multiple thin copper wires as conductors are widely used. Multiple thin copper wires can reduce the resistance of the wires themselves, improve the efficiency of the wires, and save electricity costs.

[0005] However, in actual use, when the wire is assembled with the quick-connect plug, the insulation at the end of the wire is first removed to reveal a plurality of thin copper wires. However, the plurality of thin copper wires are in a loose state at this time. In order to enable the plurality of thin copper wires to be inserted into the jack of the quick-connect plug so as to facilitate connection with the terminals in the quick-connect plug, a tool is required to twist the plurality of thin copper wires so that the plurality of thin copper wires are twisted into one strand. At this time, the plurality of thin copper wires have a certain cohesive force. However, during the process of plugging the plurality of thin copper wires into the jack of the quick-connect plug, the plurality of thin copper wires are not smooth in shape. The jack of the quick-connect plug can be quickly inserted, which affects the assembly efficiency. The copper wire may collide with the inner wall of the jack, which may cause the wire to explode and scatter, which will also affect the assembly efficiency. In particular, when the multiple thin copper wires come into contact with the terminals in the quick-connect plug, the multiple thin copper wires are loose and uneven, resulting in insufficient stability in the crimping between the terminals and the multiple thin copper wires, that is, the multiple thin copper wires cannot be stably assembled in the quick-connect plug, making it easy for the wires to be pulled out relative to the quick-connect plug, affecting the stability of the assembly structure and further affecting the reliability of the electrical connection.

[0006] In view of this, the inventor proposes the following technical solution. Utility model content:

[0007] The utility model aims to overcome the deficiencies of the prior art and provide a fast and stable assembly structure for electric wires and quick-connect plugs.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions: the quick-install and stable assembly structure of the electric wire and the quick-connect plug includes an electric wire having a plurality of thin copper wires and a quick-connect plug adapted to the electric wire, the quick-connect plug having a socket for the power supply line to pass through and a terminal located in the socket and used for crimping with the electric wire to form an electrical connection, a copper tube is also sheathed on the outside of the plurality of thin copper wires, and the copper tube is riveted to clamp and fix all the thin copper wires together, and the copper tube is electrically connected to the thin copper wires, the front end of the copper tube protrudes outside the front ends of all the thin copper wires, the copper tube is inserted into the socket, and is crimped and assembled with the terminal.

[0009] Furthermore, in the above technical solution, the rear end of the copper tube has a trumpet-shaped portion that is larger on the outside and smaller on the inside and is used to guide the thin copper wire to be inserted into the interior of the copper tube.

[0010] Furthermore, in the above technical solution, the guide and positioning portion also wraps and is fixed to the outer surface of the insulating outer sheath of the electric wire.

[0011] Furthermore, in the above technical solution, a crimping groove for terminal crimping is also formed on the outside of the copper tube.

[0012] Furthermore, in the above technical solution, the inner wall of the copper tube is also punched and torn to form a plurality of thorns, and the thorns are also inserted between the plurality of thin copper wires and clamped by the plurality of thin copper wires.

[0013] Furthermore, in the above technical solution, the outer periphery of the front end of the copper tube is also provided with a round chamfer that plays a guiding role.

[0014] Furthermore, in the above technical solution, the outer periphery of the front end of the copper tube is also formed with a rib extending from the outside to the inside, and the rib at least blocks the outermost circle of thin copper wires.

[0015] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model adds a copper tube, and after the copper tube is sleeved on the outside of multiple thin copper wires, the copper tube is fixed to the outside of all the thin copper wires by riveting, thereby clamping and fixing all the thin copper wires together, and the phenomenon of the thin copper wires spreading outward will not occur, so that the copper tube is used as a conductor for the wire to be inserted, positioned and connected with the quick-connect plug, and the copper tube has relatively large strength, and can cooperate with all the thin copper wires to be quickly inserted into the quick-connect plug, so the assembly is extremely smooth, and there will be no phenomenon of not being able to be inserted into the jack. At the same time, the copper tube and the terminal are crimped and assembled, and its stability is better, the crimping tension formed by the contact is more stable, and the copper tube is not easy to fall out, so the purpose of fast and stable assembly is achieved, and the reliability of the electrical connection between the wire and the quick-connect plug is guaranteed.

[0022] The utility model is further described below in conjunction with specific embodiments and drawings.

[0023] See Figure 1-6 As shown, a fast and stable assembly structure of an electric wire and a quick-connect plug is provided, which comprises an electric wire 1 having a plurality of thin copper wires 11 and a quick-connect plug 2 adapted to the electric wire 1, wherein the quick-connect plug 2 comprises a socket 21 for the power supply line 1 to pass through and a terminal located in the socket 21 and used for crimping with the electric wire 1 to form an electrical connection. When in use, the plurality of thin copper wires 11 at the end of the electric wire 1 are partially inserted into the socket 21 of the quick-connect plug 2, and the quick-connect plug 2 is crimped (i.e. pressed) by the terminal in the socket 21, which not only compresses and positions the plurality of thin copper wires 11 at the end of the electric wire 1, but also electrically connects the electric wire 1 to the quick-connect plug 2, thereby achieving the purpose of electrical conduction.

[0024] In order to prevent the multiple thin copper wires 11 from becoming loose after the insulating outer sheath 12 is cut off at the end of the electric wire 1, and to enable the multiple thin copper wires 11 to be quickly and smoothly inserted into the quick-connect plug 2, the utility model also makes the following design: a copper tube 3 is also sleeved on the outside of the multiple thin copper wires 11, and the copper tube 3 is riveted to clamp and fix all the thin copper wires 11 together, and the copper tube 3 is electrically connected to the thin copper wires 11, and the front end of the copper tube 3 protrudes outside the front ends of all the thin copper wires 11, and the copper tube 3 is inserted into the jack 21 and crimped and assembled with the terminal. That is to say, the utility model adds a copper tube 3, and after the copper tube 3 is sleeved on the outside of multiple thin copper wires 11, the copper tube 3 is fixed to the outside of all the thin copper wires 11 by riveting, and then all the thin copper wires 11 are clamped and fixed together, and the thin copper wires 11 will not spread outward, so that the copper tube 3 is used as a conductor for the electric wire 1 to be inserted, positioned and connected with the quick connection plug 2. The copper tube 3 is relatively strong and can cooperate with all the thin copper wires 11 to be quickly inserted into the quick connection plug 2. The assembly is extremely smooth and there will be no phenomenon of not being able to be inserted into the socket 21. At the same time, the copper tube 3 and the terminal are crimped and assembled, and its stability is better, the crimping tension formed by the contact is more stable, and the copper tube 3 is not easy to fall out, so the purpose of fast and stable assembly is achieved, and the reliability of the electrical connection between the electric wire 1 and the quick connection plug 2 is guaranteed.

[0025] The copper tube 3 may include at least the following two forms:

[0026] The first type: before being riveted, the copper tube 3 has a circular cross section, and is a conventional seamless copper tube.

[0027] The second type: before the copper tube 3 is riveted, its cross section is C-shaped, and a gap is formed on the outside, so that after being riveted later, the gap on the outside of the copper tube 3 is riveted closed to only clamp and fix all the thin copper wires.

[0028] In addition, in order to make the assembly of the copper tube 3 and the electric wire 1 faster and more stable, the following design is also made: the rear end of the copper tube 3 has a trumpet-shaped guide and positioning portion 31 that is larger on the outside and smaller on the inside and is used to guide the thin copper wire 11 to be inserted into the copper tube 3. When the thin copper wire 11 is inserted into the copper tube 3, even if some ends of the thin copper wire 11 are slightly spread outward, they will be blocked by the trumpet-shaped guide and positioning portion 31 that is larger on the outside and smaller on the inside, and guided to be inserted into the copper tube 3, thereby improving the assembly efficiency. In addition, the guide and positioning portion 31 also wraps around the outer surface of the insulating outer sheath 12 fixed to the electric wire 1, which can improve the stability of the assembly structure and make the assembly of the copper tube 3 and the electric wire 1 more stable.

[0029] The copper tube 3 is also formed with a crimping groove for terminal crimping on the outside. Of course, the crimping groove is a shallow groove, but the crimping groove can improve the stability of the copper tube 3 and the terminal after crimping, and improve the reliability of the copper tube 3 and the terminal conduction.

[0030] The inner wall of the copper tube 3 is also stamped and torn to form a plurality of thorns 33, which are also inserted between the plurality of thin copper wires 11 and clamped by the plurality of thin copper wires 11, thereby increasing the contact area between the copper tube 3 and the plurality of thin copper wires 11, so that after the copper tube 3 is riveted, the tightness between the copper tube 3 and the thin copper wires 11 is better, and the friction force is greater, thereby further preventing the copper tube 3 from accidentally detaching from the wire 1, further improving the stability of the assembly structure, and further improving the service life.

[0031] The front periphery of the copper tube 3 is also provided with a round chamfer that plays a guiding role, which can better enable the copper tube 3 to be quickly inserted into the socket 21 of the quick connection plug 2.

[0032] The front periphery of the copper tube 3 is also formed with a retaining edge 34 extending from the outside to the inside. The retaining edge 34 at least blocks the outermost circle of thin copper wires 11, and the assembly structure is more stable.

[0033] In summary, the utility model adds a copper tube 3, and after the copper tube 3 is sleeved on the outside of multiple thin copper wires 11, the copper tube 3 is fixed to the outside of all the thin copper wires 11 by riveting, and then all the thin copper wires 11 are clamped and fixed together, and the thin copper wires 11 will not spread outward, so that the copper tube 3 is used as a conductor for the electric wire 1 to be inserted, positioned and connected with the quick connection plug 2. The copper tube 3 is relatively strong and can cooperate with all the thin copper wires 11 to be quickly inserted into the quick connection plug 2. The assembly is extremely smooth and there will be no phenomenon of not being able to be inserted into the socket 21. At the same time, the copper tube 3 and the terminal are crimped and assembled, and its stability is better, the crimping tension formed by the contact is more stable, and the copper tube 3 is not easy to fall out, so the purpose of fast and stable assembly is achieved, and the reliability of the electrical connection between the electric wire 1 and the quick connection plug 2 is guaranteed.

[0034] The structure of the quick-connect plug is the same as the convenient-to-operate wiring terminal disclosed in CN110534930A, and will not be elaborated again.

[0035] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
