Technical Field

[0001] The utility model relates to the field of electrical appliance connecting wires, in particular to an electric shock prevention connecting wire and an electrical appliance with the connecting wire. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. A circular connector is a type of connector with a cylindrical basic structure and a circular mating surface. In the interconnection classification, it belongs to Class 5 and is used for interconnection between devices. As a structure that connects the two ends of a wire, male and female connectors are easily disassembled and replaced, making them widely used in various electrical connection structures. However, existing connecting wires often connect the male end to one end of the power plug and the female end to one end of the electrical appliance. When using it, it is easy to accidentally touch the male end after the plug is inserted into the socket, causing electric shock or feeling an electric shock, which poses a certain risk; at the same time, the male and female ends are prone to loosening after a certain number of plugging and unplugging, affecting use.

[0003] Chinese patent publication number CN220253632U relates to a quick-connect round hole connector, including: a female mounting shell, a male mounting shell, a sealing mechanism, a line structure 1, a wire harness structure and a plug-in structure, the female mounting shell includes a threaded sleeve 1, a sealing ring 1, a mounting sleeve and a threaded sleeve 2, and the male mounting shell includes a threaded ring 1, a fixing sleeve and a threaded ring 2. The utility model is provided with a plug-in structure. When in use, the stab-shaped male plug is plugged into the plug-in hole 1. The stab-shaped male plug is used so that the male plug can be quickly plugged into the plug-in hole. At the same time, the corresponding digital identification is used to facilitate the rapid alignment of the angle of the line mounting block and the mounting component. The stab part of the stab-shaped male plug has a certain guiding effect, which can save installation time and does not require the staff to calibrate the male plug and the plug-in hole one by one, greatly improving the installation efficiency of the connector. In this patent, the male end is connected to one end of the plug. When using it, it is easy to get an electric shock if the male end is accidentally touched. There is a certain risk in use.

[0004] Chinese patent publication number CN117317708A provides a high-current connector assembly with an anti-slip function, which belongs to the field of connector technology; it includes a female plug connected to a power cord and a male plug connected to an electrical wire, the front and rear ends of the left side of the female plug are respectively provided with a first plug post and a second plug post, the first plug post and the second plug post are respectively connected to the wires in the power cord, the left sides of the first plug post and the second plug post are both provided with a plug hole, and the front and rear ends of the right end of the male plug are respectively provided with a first plug piece and a second plug piece. The present invention inserts the spring piece on the right side of the male plug into the plug hole, and after power is turned on, the connection will generate heat when a large current passes through, and the heat generated will enter the cavity, and at the same time, the memory spring is heated and deformed with a heating resistor, so that it is firmly fixed in the plug hole. Since the heat in the cavity will not cool down during the power-on process, the push block will not be reset at this time, so that the connector cannot be unplugged at will when it is powered on, achieving the effect of anti-slipping, and it is very safe to use. Although the patent connects the male end to the electrical appliance and the female end to the power cord, it cannot be plugged and unplugged frequently, and cannot meet the plug-in and unplug action after use.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments.

A mesh tail 4 is provided on the outside of the connection between the female end and the wire. When the male end is inserted into the female end, since the conductive part of the female end is not exposed, when the wire is inserted into the plug, the human body is prevented from touching the conductive part of the female end to cause contact, which is safer.

[0037] Specifically, Figure 2-3 As shown, the female end 3 includes a turn tail 30, and two groups of terminals 31 arranged in the turn tail, the two groups of terminals 31 are connected to the wire 1 respectively, and the turn tail is also provided with a large electrode 33 and a small electrode 32 respectively contacting the two groups of terminals, the large electrode and the small electrode are arranged without contact, so that the current is transmitted to the large electrode and the small electrode through the terminal 31 and conduction. It should be noted that the large electrode 33 and the small electrode 32 are both arranged in the turn tail. The male end 2 includes a turn tail 20, and a copper needle 23 sleeved in the turn tail, one end of the copper needle is connected to the electrical appliance, and the other end is partially exposed from the turn tail, the outer wall of the turn tail is sleeved with a copper sleeve 22, one end of the copper sleeve is connected to the electrical appliance, and a turn tail sleeve 21 is arranged outside the copper sleeve. When the male end 2 is inserted into the female end 3, the copper sleeve 22 contacts the large electrode 32, and the copper needle 23 contacts the small electrode 33, so that the current is transmitted from the wire to the electrical appliance to power the electrical appliance for operation.

[0038] Furthermore, if Figure 4-9 As shown, the outer wall of the tail 30 is provided with multiple groups of fastening grooves 300, and the end of the net tail 4 is sleeved in the fastening groove to fix the net tail, and the net tail is sleeved on the outside of the side where the tail is connected to the wire, so that the wire is connected and fixed to the terminal. A partition plate is provided in the tail 30 to divide the inner wall of the tail into an electrode chamber 301 and a terminal chamber 308. The terminal 31 is provided in the terminal chamber, the large electrode 33 and the small electrode 32 are provided in the electrode chamber, and the ends of the large electrode and the small electrode are both located in the electrode chamber. An electrode separator column 303 is provided in the electrode chamber 301, and a large electrode chamber 3010 is formed between the outer wall 3031 of the electrode separator column and the inner wall of the tail, the large electrode 33 is fixed in the large electrode chamber, the inner wall 3030 of the electrode separator column forms a small electrode chamber 3011, and the small electrode 32 is fixed in the small electrode chamber, so as to avoid the large electrode and the small electrode from contacting and short-circuiting.

[0039] Furthermore, if Figure 6-8 As shown, in order to further avoid the large electrode and the small electrode from short-circuiting, the large electrode 33 is located at the upper end of the large electrode separator column 301, and the small electrode is placed in the small electrode separator column, so that the large electrode and the small electrode are not on the same vertical plane. The radius of the large electrode chamber 3010 is larger than that of the small electrode chamber 3011, and the radius of the large electrode is larger than the radius of the electrode separator column, and the radius of the small electrode is smaller than the radius of the electrode separator column, so that the large electrode cannot enter the small electrode chamber.

[0040] Furthermore, if Figure 6-7 and Fig. 9 As shown, two groups of electrode perforations 306 are provided on the partition plate, and the two groups of electrode perforations are respectively provided on opposite surfaces, preferably at the two ends of the inner wall diameter of the tail, and one end of the large electrode and the small electrode respectively passes through the electrode perforations and is fixedly contacted with the terminal. Electrode perforation protrusions 3060 are also provided on the electrode perforation 306, and the electrode perforation protrusions are arranged toward the outer wall of the tail so as to generate extrusion force on the motor to make the electrode contact with the inner wall of the tail to prevent the electrode from shaking. Two groups of first blocking columns 302 are also provided on the inner wall of the tail, and the two groups of first blocking columns contact the outer wall of the large electrode to generate a stopping force to prevent the large electrode from shaking. Preferably, the two groups of first blocking columns are at the two ends of the same diameter of the inner wall of the tail, and the virtual diameter of the first blocking column connection line is perpendicular to the virtual diameter of the electrode perforation, and two groups of large motor end support columns 307 are also provided on the corresponding side of the small electrode perforation, so as to achieve full support for the large electrode, better restricting effect on the large electrode, and also prevent the large electrode from sliding down and contacting the small electrode. An opening is provided at one end of the electrode separation column 303, a first stop column 304 is provided at the opening, and the small electrode sleeve is arranged on the first stop column for limiting.

[0041] Furthermore, if Figure 9-10 As shown, the side where the tail 30 is connected to the wire is a terminal chamber 308, in which the terminal is fixedly arranged, and one end is fixedly connected to the wire, and the other end is fixedly connected to the large electrode and the small electrode. An eccentric arc opening 309 is also provided on the side of the tail facing the terminal chamber, which is convenient for connecting and opening the mold with the net tail 4. The terminal 31 includes at least two sets of wire connection parts 310, on which the wire is fixed, and a fixed connection setting can be selected; it also includes a terminal seat 314 connected to the electrode, and the electrode is connected and fixed to the terminal seat.

[0042] Furthermore, if Figure 10-12As shown, two sets of bending parts 312 are provided on the terminal 314, and an electrode fixing part 313 is left between the bending part and the terminal seat 314. The electrode terminal connecting part is inserted into the electrode fixing part to connect the electrode with the terminal. A terminal inclined part 311 is provided on the terminal seat, and a terminal protrusion 3110 is provided on the terminal inclined part. A jack is provided on the electrode corresponding to the terminal protrusion, so as to connect and fix the motor with the terminal. The large electrode 32 includes a large electrode terminal connection part 321, a large electrode stopper part 323 and a copper sleeve contact part 320 integrally formed with the large electrode terminal connection part. The large electrode stopper part is arranged between the large electrode terminal connection part and the copper sleeve contact part, and the width of the large electrode stopper part 323 is greater than that of the large electrode terminal connection part 321. When the large electrode is installed in the electrode chamber, the large electrode terminal connection part is passed through the electrode through-hole 306 until the large electrode stopper part 323 contacts the partition plate. At this time, the large electrode inclined part 322 arranged on the large electrode stopper part 323 is flush with the large electrode terminal connection part due to the squeezing force of the electrode plug hole. When the squeezing force disappears, the large electrode inclined part resumes its inclination and fixes the large electrode. At this time, the large electrode cannot be separated from the tail without squeezing the large electrode inclined part. Since the large electrode plug hole 325 arranged on the large electrode terminal connection part is connected to the terminal protrusion 3110, the large electrode is stably connected in the tail and connected to the terminal, and there is no worry that the large electrode will fall off or not contact the terminal during the plugging and unplugging process, and the connection stability is higher. A large electrode protrusion 324 is provided on the large electrode stopper 323, and an electrode separation column protrusion 3032 is correspondingly provided on the outer wall of the electrode separation column, so that the large electrode and the inner wall of the tail are more firmly in contact. A copper sleeve contact portion gap 326 is left between the two groups of copper sleeve contact portions 320, so that the copper sleeve can move to a certain extent when in contact with the large electrode, so that the clamping radius of the copper sleeve contact portion can change to a certain extent, and the copper sleeve is conveniently inserted into the copper sleeve contact portion. The small electrode 32 has a basically the same structure as the large electrode, except that the large electrode stopper is not provided, the small electrode terminal contact portion 331 passes through the electrode perforation, so that the small electrode jack 333 is connected and fixed with the terminal protrusion, and the small motor inclined portion 332 connects and fixes the small electrode with the tail, and the second stopper 304 is located between the two groups of copper needle contact portions 330 to limit the left and right movement of the small electrode within a controllable range, and a copper needle contact portion gap 334 is also provided between the two groups of copper needle contact portions. In order to facilitate the fixation of the copper needle after insertion, a copper needle cavity 305 is also provided in the rotating tail 30. The copper needle cavity is at the lower end of the small electrode cavity and has a radius smaller than the small electrode cavity, so that the copper needle can completely pass through the small electrode into the copper needle cavity after insertion to ensure that the small electrode is in contact with the copper needle.

[0043] Furthermore, if Figure 13-15As shown, the male end 2 includes a spiral tail 20, a copper needle 23 arranged in the spiral tail, a copper sleeve 22 sleeved on the outer wall of the spiral tail, and a spiral tail sleeve 21 sleeved on the outside of the spiral tail sleeve. The tail 20 is cylindrical, with an outer portion 200 at one end, and a notch 201 on the outer protrusion. The copper sleeve 23 includes a copper sleeve large electrode contact portion 220 sleeved on the tail, and an electrical copper sleeve connection end 221 integrally formed with the copper sleeve large electrode contact portion. The electrical connection line or conductive end is connected to the electrical channel connection end. The tail sleeve 21 is sleeved on the outside of the copper sleeve large electrode contact portion, and a copper sleeve inclined portion 223 is provided on the electrical copper sleeve connection end. When the copper sleeve is sleeved on the copper sleeve contact surface 202 outside the tail, the copper sleeve inclined portion contacts the upper end 210 of the rotating sleeve, thereby preventing the copper sleeve from falling off or moving. The electrical copper sleeve connection end is provided with an electrical fixing hole 222, and the copper sleeve is fixed by the outer protrusion and the upper end of the tail sleeve to prevent the copper sleeve from moving during the plugging and unplugging process. The width of the tail sleeve should be smaller than the width of the copper sleeve large electrode contact portion 220, so that part of the copper sleeve large electrode contact portion is exposed. The copper needle 23 includes a copper needle small electrode contact part 230, a copper needle fixing part 231 and an electrical copper needle connection end 232 integrally formed with the copper needle small electrode contact part, and the radius of the copper needle fixing part is larger than the copper needle small electrode contact part and the electrical copper needle connection end. A hollow channel is arranged inside the tail, as well as a third chamber 205 for accommodating the copper needle small electrode contact part, a second chamber for fixing the copper needle fixing part and a first chamber for fixing the electrical copper needle connection part, the corresponding second chamber radius is larger than the first chamber and the third chamber, and the second chamber width is the same as the copper needle fixing part width, and the copper needle is fixed to the tail inner shell to prevent it from moving and is not affected by plugging and unplugging. It should be noted that the end of the copper needle small electrode contact part should extend out of the hollow channel of the tail. An external protrusion 200 is also arranged on the outside of the tail sleeve, and when the male end is inserted into the female end, the external protrusion contacts the tail, indicating that the insertion is completed.

[0044] During assembly, during production, the copper needle 23 is fixed in the tail 20, and one end of the copper needle is extended out of the tail, and the copper sleeve 23 is sleeved on the copper sleeve contact surface 202. After the electrical copper sleeve connection end 221 passes through the notch 201, the tail sleeve 21 is sleeved outside the copper sleeve and connected and fixed with the tail. At this time, the copper sleeve inclined portion 223 contacts the tail sleeve to generate a stopping force, and then the electrical interface is connected and fixed with the electrical copper sleeve contact portion 222 and the electrical copper needle connection end 232. At this time, the male end and the electrical connection assembly are completed. The large electrode 32 is inserted into the electrode perforation, and the electrode passes through so that the large electrode inclined portion 322 is forced to move until the large electrode passes through the electrode perforation 306, and the large electrode stop portion 323 contacts the partition plate. At this time, the large electrode terminal connection portion 321 enters the terminal chamber, and the large electrode inclined portion 323 is not subjected to the squeezing force of the electrode perforation to restore the inclined state and contact the lower end surface of the partition plate, so that the large electrode is connected to the tail through the large electrode stop portion and the large electrode inclined portion. At the same time, the electrode perforated protrusion 3060 generates a squeezing force on the large electrode protrusion 324 to make the large electrode in close contact with the inner wall of the tail, thereby preventing the large electrode from shaking left and right. The copper sleeve contact part 320 is placed on the upper end of the electrode separation column 303, and the first stop column 302 generates a squeezing force on the two groups of copper sleeve contact parts to prevent the copper sleeve contact parts from shaking left and right. The end of the copper sleeve contact part is placed on the large motor end support column 307 to prevent the large electrode gap side from falling. Then the large electrode terminal connection part 321 is inserted into the motor fixing part 313 until the large electrode inclined part is placed above the terminal inclined part 311. At this time, the terminal protrusion 3110 is located at the large electrode jack 325, and the terminal inclined part also generates a supporting force on the large electrode inclined part to prevent the large electrode inclined part from moving. The small electrode 32 is assembled in a similar manner, which will not be repeated here. Finally, the wire connection section 310 is connected to the wire, and the net tail 4 is connected to the tail, thereby completing the connection and fixation between the female end and the wire.

[0045] When in use, insert the male end 2 into the female end 3, so that the copper needle 23 enters the copper needle contact part 330 and contacts the copper needle contact part, and continue to insert the copper sleeve 22 into the copper sleeve contact part 320 and contact the copper sleeve contact part, until the outer protrusion 200 contacts the turn tail, and the insertion is completed, so that the current flows from the wire through the terminal, the large electrode and the small electrode, the copper sleeve and the copper needle, and then flows into the electrical power supply for use. When the male end needs to be pulled out, force is applied to the male end. Since the inclined part of the large electrode, the inclined part of the small electrode and the inclined part of the copper sleeve are all in an inclined state, it is prevented from falling off when pulled out, which is convenient for next use.

The plug can be inserted into the socket to power the electrical appliance, and the male end can be directly pulled out from the female end, and the female end can be used to connect with the male end of other electrical appliances. Since the male end is set in the tail, it can prevent the human body from accidentally contacting the electrode, which is safer.
