Description

Technical Field

[0001] The utility model relates to the technical field of connecting plugs, in particular to a portable connecting plug. Background Art

[0002] A portable connecting plug, also known as a quick-connect plug, is an electrical connector that can be quickly connected and disconnected. The design of this plug aims to improve connection efficiency, simplify the operation process, and enhance the convenience of use.

[0003] During the use of the connector, if the contact part between the connector plug and the socket or electrical equipment is loose or has problems such as oxidation and dirt, it will cause an increase in contact resistance. When the current passes through these poorly contacted areas, additional heat will be generated, causing the wire to heat up. In addition, if the electrical equipment connected by the connector plug has too high a power, exceeding the carrying capacity of the wire or plug, then the wire will generate a large amount of heat during current transmission, resulting in heating. However, the connecting wires in the prior art do not have a temperature feedback function, and the staff cannot intuitively know the temperature of the wire. The lack of a temperature feedback function makes it impossible for the staff to take timely measures to reduce the wire temperature.

[0004] Therefore, it is necessary to design a portable connecting plug to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a portable connecting plug.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A portable connecting plug includes:

[0008] A male connector;

[0009] A female connector, plugged into the male connector;

[0010] Two connecting cables, one of the connecting cables is connected to the male connector, and the other connecting cable is connected to the female connector;

[0011] Two temperature feedback structures, respectively arranged on the two connecting cables;

[0012] Two display structures, respectively arranged on the two temperature feedback structures.

[0013] As a preferred technical solution of the utility model, the temperature feedback structure includes:

[0014] An annular cylinder, fixedly sleeved on the connecting cable;

[0015] A ring-shaped sliding plug, sealingly and slidably connected to the inner surface of the ring-shaped cylinder;

[0016] Thermally expandable gas, filled between the ring-shaped cylinder and the ring-shaped sliding plug;

[0017] A return spring, one end connected to the inner surface of the ring-shaped cylinder and the other end connected to the ring-shaped sliding plug.

[0018] As a preferred technical solution of the present invention, the display structure includes:

[0019] An opening, formed on the ring-shaped cylinder;

[0020] Scale lines, provided on the outer peripheral surface of the ring-shaped cylinder and facing the opening;

[0021] A glass sheet, fixed in the opening.

[0022] As a preferred technical solution of the present invention, the opening is strip-shaped and arranged along the axial direction of the ring-shaped cylinder.

[0023] As a preferred technical solution of the present invention, the glass sheet is made of transparent glass.

[0024] As a preferred technical solution of the present invention, the ring-shaped cylinder is made of pure copper material.

[0025] The present invention has the following beneficial effects:

[0026] Through the expansion of the thermally expandable gas accumulated in the ring-shaped cylinder as the temperature rises, the ring-shaped sliding plug is pushed to move, realizing the real-time monitoring of the temperature of the connecting cable. This non-contact temperature sensing method is both safe and efficient, avoiding the risk of damage to traditional temperature sensors that may be caused by direct contact with high-temperature cables. The scale lines provided on the ring-shaped cylinder enable the staff to directly judge the current temperature of the connecting cable quickly and accurately by observing the position of the ring-shaped sliding plug on the scale lines. This intuitive design greatly simplifies the temperature detection process, improves work efficiency, and provides clear warning signals for the staff, which helps to timely discover and handle potential overheating problems and prevent fires or other safety accidents caused by excessive cable temperature.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Referring to Figures 1-4 , a portable connection plug includes a male connector 1; a female connector 2, which is plugged on the male connector 1; two connecting cables 3, one of the connecting cables 3 is connected to the male connector 1, and the other connecting cable 3 is connected to the female connector 2; two temperature feedback structures, which are respectively arranged on the two connecting cables 3; two display structures, which are respectively arranged on the two temperature feedback structures;

[0034] The temperature feedback structure includes: an annular cylinder 41, which is fixedly sleeved on the connecting cable 3. The annular cylinder 41 is made of pure copper material, and the pure copper material has high thermal conductivity, which is convenient for the annular cylinder 41 to heat up; an annular sliding plug 42, which is hermetically slidably connected to the inner surface of the annular cylinder 41; a thermally expandable gas, which is filled between the annular cylinder 41 and the annular sliding plug 42; a return spring 43, one end of which is connected to the inner surface of the annular cylinder 41, and the other end is connected to the annular sliding plug 42. The display structure includes: an opening 51, which is opened on the annular cylinder 41. The opening 51 is in a long strip shape and is arranged along the axis direction of the annular cylinder 41; a scale line 52, which is arranged on the outer peripheral surface of the annular cylinder 41 and is arranged opposite to the opening 51; a glass sheet 53, which is fixed in the opening 51. The glass sheet 53 is made of transparent glass, and the transparent glass is convenient for the staff to observe the position of the annular sliding plug 42 through the glass sheet 53.

[0035] The specific working principle of the present invention is as follows:

[0036] When the portable connecting plug proposed by the utility model is in use, when the temperature of the connecting cable 3 rises, the annular cylinder 41 will also be heated, and its internal temperature will also rise. There is thermally expandable gas stored inside the annular cylinder 41. According to the principle of thermal expansion and contraction, when the internal temperature of the annular cylinder 41 rises, the thermally expandable gas stored inside it will also be heated and expand. The volume occupied by the expanded thermally expandable gas will become larger, which enables the thermally expandable gas to push the annular sliding plug 42, causing the annular sliding plug 42 to move. Therefore, the staff can judge the temperature of the connecting cable 3 through the position of the annular sliding plug 42. There are scale lines 52 provided on the annular cylinder 41, and the staff can accurately judge the position of the annular sliding plug 42 according to the scale lines 52, so as to accurately judge the temperature of the connecting cable 3. When the temperature of the connecting cable 3 is too high, the staff can take corresponding measures in time to deal with the situation of the too high temperature of the connecting cable 3;

[0037] For thermally expandable gas, the gas is composed of a large number of molecules. These molecules are constantly moving randomly, and there are mutual gravitational and repulsive forces between the molecules. When the gas is heated, the random movement of the molecules will intensify, resulting in an increase in the average distance between the molecules, thereby causing the volume of the gas to expand. Preferably, carbon dioxide gas can be selected as the thermally expandable gas. Carbon dioxide gas has a high coefficient of thermal expansion and strong stability.

[0038] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
