Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment, and in particular to a cold-end wiring device. Background Technology

[0002] Double-armored thermocouples have a thicker outer wall, corresponding to a smaller size for the single-armored thermocouple inside. Due to the thinner thermocouple wires, the strength of the wires and the welded area at the cold junction is relatively low after the thinner wires are welded to the conductor. During manufacturing or use, the wires and welded area near the cold junction are prone to open circuits due to external forces. Especially in vibration environments, the cold junction components are very likely to open circuit, leading to product failure and seriously affecting the product's manufacturing quality and service life. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a cold-end wiring device to solve the technical problem that the coupling wire and welding area near the cold-end wiring position are prone to open circuit due to external force in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides a cold-end wiring device, comprising:

[0005] The first connector is used to connect to the cold junction of the thermocouple;

[0006] The second connector is used to connect to the end of the conductive cable;

[0007] A connecting part is located between the first connector box and the second connector. The connecting part is used to connect the first connector and the second connector. A connection area is formed between the first connector and the second connector. The connection area is used to connect the cold end of the thermocouple to the end of the conductive cable.

[0008] The advantages of the above technical solution are that by clamping the first connector to the outer wall of the thermocouple cable and the second connector to the outer wall of the conductor, the thermocouple wire and the conductor are welded in the welding area. This means that the welding area between the thermocouple cable and the conductor no longer bears the external force. Instead, the external force is borne by the newly added cold-end connection device, which has a strength much higher than that of the thermocouple wire and the welding area between the thermocouple wire and the conductor. This completely solves the problem of product open circuit and failure caused by the thin diameter of the thermocouple wire and the insufficient strength of the thermocouple wire and the welding area between the thermocouple wire and the conductor. In this way, the vibration resistance of the double-armored thermocouple product is improved and the service life of the product is extended.

[0009] Optionally, the first connector and the second connector include an unfolded state and a bent state. In the unfolded state, the first connector and the second connector are in the form of a sheet, and the opposite sides of the first connector and the second connector can be bent toward the same side to complete the switch from the unfolded state to the bent state.

[0010] Optionally, the opposite sides of the first connector are bent to form a first slot for engaging the cold junction of the thermocouple.

[0011] Optionally, the opposite sides of the second connector are bent to form a second slot for engaging the conductive cable.

[0012] Optionally, in the unfolded state, the width of the connecting portion is smaller than the widths of the first connector and the second connector.

[0013] Optionally, the first connector and the second connector are bent in the same direction.

[0014] Optionally, the bending directions of the first connector and the second connector are opposite.

[0015] Optionally, the first connector, the second connector, and the connecting portion are integrally formed.

[0016] Optionally, the first connector, the second connector, and the connecting part are made of metal.

[0017] Optionally, the first connector, the second connector, and the connecting portion are made of copper.

[0018] As described above, the cold-end connection device of this utility model has the following beneficial effects: the first connector is clamped to the outer wall of the thermocouple cable, and the second connector is clamped to the outer wall of the conductor. The thermocouple wire and the conductor are welded in the welding area, so that the welding area between the thermocouple cable and the conductor no longer bears the external force. Instead, the external force is borne by the newly added cold-end connection device, which has a strength much higher than that of the thermocouple wire and the welding area between the thermocouple wire and the conductor. This completely solves the problem of product open circuit and failure caused by the thin diameter of the thermocouple wire and the insufficient strength of the thermocouple wire and the welding area between the thermocouple wire and the conductor. In this way, the vibration resistance of the double-armored thermocouple product is improved and the service life of the product is extended. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] Please see Figures 1 to 5 It should be noted that the illustrations provided in this embodiment are merely schematic representations of the basic concept of this utility model. The illustrations only show components relevant to this utility model and are not drawn according to the actual number, shape, and size of the components in implementation.

The structures, proportions, sizes, etc., shown in the accompanying drawings are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0033] Please see Figures 1 to 5 As shown, this utility model provides a cold-end wiring device, comprising:

[0034] The first connector 1 is used to connect to the cold junction of the thermocouple;

[0035] The second connector 3 is used to connect to the end of the conductive cable;

[0036] A connecting part 2 is located between the first connector 1 and the second connector 3. The connecting part 2 is used to connect the first connector 1 and the second connector 3. A connection area is formed between the first connector 1 and the second connector 3. The connection area is used to connect the cold end of the thermocouple to the end of the conductive cable.

[0037] It should also be noted that during use, the first connector 1 is clamped to the outer wall of thermocouple a, and the second connector 3 is clamped to the outer wall of conductor / cable b. The thermocouple a and conductor / cable b are welded together in the welding area to form a welding point c. This means that the welding area between thermocouple a and conductor / cable b no longer bears external force. Instead, the external force is borne by the newly added cold-end connection device, which has a strength much higher than that of the thermocouple wire and the welding area between the thermocouple wire and conductor / cable b. This completely solves the problem of product open circuit and failure caused by the thinner diameter of the thermocouple wire and the insufficient strength of the thermocouple wire and the welding area between the thermocouple wire and the conductor. This improves the vibration resistance of the double-armored thermocouple product and extends its service life.

[0038] For example, the first connector 1 and the second connector 3 include an unfolded state and a bent state. In the unfolded state, the first connector 1 and the second connector 3 are in the form of a sheet, and the opposite sides of the first connector 1 and the second connector 3 can be bent toward the same side to complete the switch from the unfolded state to the bent state.

[0039] For example, the opposite sides of the first connector 1 are bent to form a first slot for engaging the cold junction of the thermocouple.

[0040] For example, the opposite sides of the second connector 3 are bent to form a second slot for engaging the conductive cable.

[0041] For example, in the unfolded state, the width of the connecting part 2 is smaller than the width of the first connector 1 and the second connector 3.

[0042] For example, the first connector 1 and the second connector 3 are bent in the same direction.

[0043] It should also be noted that the purpose of having the bending direction of the first connector 1 and the second connector 3 on the same side of the connecting part 2 is to make the entire wiring device more compact, reduce the space occupied, and also help improve the stability and reliability of the device.

[0044] For example, the bending directions of the first connector 1 and the second connector 3 are opposite.

[0045] It should also be noted that the purpose of the bending directions of the first connector 1 and the second connector 3 being located on different sides of the connecting part 2 is to enable the entire wiring device to cope with various connection states and improve the adaptability of the wiring device of this application.

[0046] For example, the first connector 1, the second connector 3, and the connecting part 2 are integrally formed.

[0047] It should also be noted that the purpose of the first connector 1, the connecting part 2, and the second connector 3 being a single-piece molded structure is to reduce the number of connection points between components, thereby improving the mechanical strength and electrical performance of the device. At the same time, the single-piece molded structure also facilitates manufacturing and processing, reducing manufacturing costs. This design helps to improve the overall performance and reliability of the wiring device.

[0048] For example, the first connector 1, the second connector 3 and the connecting part 2 are made of metal.

[0049] It should also be noted that metal materials have good electrical conductivity and mechanical strength, making them suitable for manufacturing wiring devices that need to withstand current and mechanical stress. In highly corrosive environments, materials such as stainless steel or special alloys can be used.

[0050] For example, the first connector 1, the second connector 3 and the connecting part 2 are made of copper.

[0051] It should also be noted that by using copper, pliers can be used to force the two ends of the first connector 1 to fit better against the outer wall of the thermocouple cable, so as to better adapt to thermocouple cables and wires of different diameters and improve the tightness and stability of the connection. Copper is a metal with excellent conductivity and relatively low cost. Therefore, using copper can further improve the conductivity of the wiring device while reducing manufacturing costs.

[0052] For example, the connecting part 2 is elongated, the middle part of the first connector 1 is connected to one end of the connecting part 2, and the middle part of the second connector 3 is connected to the other end of the connecting part 2.

[0053] It should also be noted that the middle part of the first connector 1 is connected to one end of the connecting part 2, and the middle part of the second connector 3 is connected to the other end of the connecting part 2. This connection method ensures that the first connector 1 and the second connector 3 will not be affected by the connection with the connecting part 2 when they are bent.

[0054] For example, the first connector 1 and the second connector 3 in this solution can also be elastically snapped together to the outer wall of the thermocouple and the outer wall of the wire, respectively.

[0055] It should also be noted that, in order to further improve the convenience of connection, the first connector 1 and the second connector 3 are set as cylindrical or semi-circular structures, and pre-threaded on the outer wall of the thermocouple cable and the outer wall of the conductor. The outer wall of the thermocouple cable and the outer wall of the conductor can also be connected by plug-in and threaded connection methods.

[0056] In summary, the cold-end connection device of this utility model clamps the first connector 1 to the outer wall of thermocouple a and the second connector 3 to the outer wall of conductor / cable b. The thermocouple a and conductor / cable b are welded together in the welding area to form a welding point c. This eliminates the external force on the welding area between thermocouple a and conductor / cable b. Instead, the external force is borne by the newly added cold-end connection device, whose strength is far greater than that of the thermocouple wire and the welding area between the thermocouple wire and the conductor. This completely solves the problem of product open circuits and failures caused by the thin diameter of the thermocouple wire and insufficient strength of the thermocouple wire and the welding area between the thermocouple wire and the conductor. Furthermore, it improves the vibration resistance of double-armored thermocouple products and extends their service life.

[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
