Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a temperature measurement structure and a secondary terminal assembly. Background Art

[0002] Secondary terminals are the points in the power system used to connect low-voltage current, voltage, signal and control cables to related equipment or devices. In the control cabinets, protection screens, intelligent devices, etc. of substations or other power facilities, secondary terminals act as a bridge. They connect the signal lines from various monitoring and control devices with the control circuits of the main equipment to achieve data transmission and the execution of control instructions. These terminals are usually designed to be small and dense so that a large number of cables can be connected in a limited space, but they may also cause heat due to poor contact, overload or aging, which may affect the normal operation of the equipment or cause safety hazards. Therefore, monitoring the heating of secondary terminals is an important task in the maintenance of power equipment.

[0003] In related fields, infrared temperature measuring instruments are usually used to monitor the heating conditions of secondary terminals. However, in some power equipment, there are many components and cables, and the installation space is relatively cramped, so it is difficult for workers to use infrared temperature measuring instruments to accurately measure the temperature of secondary terminals.

[0032] like Figures 1 to 3As shown, the present application provides a temperature measuring structure for measuring the temperature of a secondary terminal 1, the secondary terminal 1 having a terminal socket 2, an embodiment of the temperature measuring structure of the present application comprises: a base 10, a heat conductive member 20, and a temperature measuring member 30; the heat conductive member 20 is arranged on the base 10 and can be inserted into the terminal socket 2, the heat conductive member 20 has a heat conductive state that is abutted against the inner wall of the terminal socket 2 and a separated state that is spaced apart from the inner wall of the terminal socket 2, when the heat conductive member 20 is inserted into the terminal socket 2, the heat conductive member 20 can switch from the separated state to the heat conductive state, and when the heat conductive member 20 is withdrawn from the terminal socket 2, the heat conductive member 20 can switch from the heat conductive state to the separated state; the temperature measuring member 30 is arranged on the base 10.

[0033] According to the technical solution of the present embodiment, the secondary terminal 1 has a terminal jack 2, the temperature measuring structure uses the terminal jack 2 to measure the temperature of the secondary terminal 1, the base 10 is used to provide an installation basis for the various components of the temperature measuring structure, the temperature measuring element 30 is arranged on the base 10, the temperature measuring element 30 can measure the temperature, so that the staff can obtain the temperature information, the heat conductive element 20 is arranged on the base 10 and can be inserted into the terminal jack 2, the heat conductive element 20 has a heat conductive state of abutting against the inner wall of the terminal jack 2 and a separation state of being spaced apart from the inner wall of the terminal jack 2; when the heat conductive element 20 is in the heat conductive state, the heat conductive element 20 abuts against the inner wall of the terminal jack 2, so that the heat of the secondary terminal 1 is transferred to the heat conductive element 20 through the terminal jack 2, and then transferred to the base 10 , and finally transmitted to the temperature measuring element 30, so that the temperature measuring element 30 can measure the temperature of the secondary terminal 1; when the heat conductive element 20 is in the separated state, the heat conductive element 20 and the inner wall of the terminal jack 2 are spaced apart, and the temperature measuring structure no longer measures the temperature of the secondary terminal 1; when the heat conductive element 20 is inserted into the terminal jack 2, the heat conductive element 20 switches from the separated state to the heat conductive state, thereby realizing the establishment of a heat conductive path from the secondary terminal 1 to the temperature measuring element 30, and when the heat conductive element 20 is withdrawn from the terminal jack 2, the heat conductive element 20 switches from the heat conductive state to the separated state; with such a setting, compared with the solution of using an external infrared thermometer for temperature measurement in the related art, the temperature measuring structure of this embodiment can obtain the temperature information of the secondary terminal 1 through the temperature measuring element 30 without the staff performing additional operations. Therefore, the technical solution of this embodiment can effectively solve the problem that it is difficult for the staff in the related art to measure the temperature of the secondary terminal.

[0034] It should be noted that the terminal jack 2 of the secondary terminal 1 is usually set as a test jack, which is used for the staff to use test instruments to test the voltage, current and other factors of the secondary terminal 1. It is not a jack commonly used when the secondary terminal 1 is working. This embodiment uses this jack to measure the temperature of the secondary terminal 1. When the staff needs to test the above factors, the temperature measurement structure can be separated and connected from the secondary terminal 1.

[0035] like Figures 1 to 3 As shown, the heat conducting member 20 includes an elastic heat conducting plate 21, a first end of which is connected to the base 10, and when the heat conducting member 20 is in a heat conducting state, the elastic heat conducting plate 21 is deformed and abuts against the inner wall of the terminal plug hole 2, and when the heat conducting member 20 is in a separated state, the elastic heat conducting plate 21 is spaced apart from the inner wall of the terminal plug hole 2. Specifically, the setting of the elastic heat conducting plate 21 enables the elastic heat conducting plate 21 to be deformed and abuts against the inner wall of the terminal plug hole 2 when the heat conducting member 20 is inserted into the terminal plug hole 2, thereby switching the heat conducting member 20 from the separated state to the heat conducting state, and when the heat conducting member 20 is withdrawn from the terminal plug hole 2, the elastic heat conducting plate 21 returns to its original state, thereby enabling the elastic heat conducting plate 21 to be spaced apart from the inner wall of the terminal plug hole 2, thereby switching the heat conducting member 20 from the heat conducting state to the separated state.

[0036] In addition, the elastic heat conductive plate 21 is made of metal. The elastic heat conductive plate 21 has the ability of elastic deformation and heat conduction. In the present embodiment, the elastic heat conductive plate 21 is made of copper. Copper is a metal with excellent physical properties, especially in elastic deformation and heat conduction. In terms of elastic deformation, copper has a high elastic modulus, which means that it can produce a large elastic deformation when subjected to external force, and can return to its original shape after the external force is removed. Copper also has very good ductility and can be stretched into very thin wires or pressed into thin sheets. In addition, copper also has strong fatigue resistance and can maintain good elasticity and shape even under repeated stress. In terms of thermal conductivity, copper has excellent thermal conductivity and its thermal conductivity coefficient is also among the best in metals, which means that copper can conduct heat quickly and is an ideal material for applications requiring efficient heat conduction.

[0037] In addition, the thickness of the elastic heat conductive plate 21 is greater than or equal to 0.5 mm and less than or equal to 0.8 mm. Specifically, the elastic heat conductive plate 21 that meets the above requirements can ensure that the temperature measuring structure can be deformed smoothly when inserted, and can ensure that the elastic heat conductive plate 21 is not easily broken when deformed. In this embodiment, the thickness of the elastic heat conductive plate 21 can be 0.5 mm, 0.68 mm, 0.75 mm or 0.8 mm.

[0038] like Figures 1 to 3 As shown, there are multiple elastic heat-conducting plates 21, and the multiple elastic heat-conducting plates 21 are arranged at intervals along the circumferential direction of the terminal insertion hole 2. Specifically, the multiple elastic heat-conducting plates 21 can increase the contact area between the heat-conducting member 20 and the inner wall of the terminal insertion hole 2, thereby ensuring the heat transfer efficiency, and also enabling the temperature measurement structure to more truly reflect the working temperature of the secondary terminal 1.

[0039] like Figures 1 to 3As shown, there are multiple elastic heat-conducting plates 21, and the multiple elastic heat-conducting plates 21 are arranged at intervals along the circumferential direction of the terminal socket 2. The heat-conducting member 20 also includes a heat-conducting block 22. The second ends of the multiple elastic heat-conducting plates 21 are all connected to the heat-conducting block 22. When the heat-conducting member 20 is in a heat-conducting state, the heat-conducting block 22 abuts against the bottom wall of the terminal socket 2 and causes the multiple elastic heat-conducting plates 21 to deform. Specifically, the second ends of the multiple elastic heat-conducting plates 21 are all connected to the heat-conducting block 22. When the bottom wall of the terminal socket 2 squeezes the heat-conducting block 22, the heat-conducting block 22 can drive the multiple elastic heat-conducting plates 21 to elastically deform synchronously, so that the multiple elastic heat-conducting plates 21 can abut against the side wall of the terminal socket 2 to transfer heat, ensuring the consistency of the deformation of the multiple elastic heat-conducting plates 21.

[0040] like Figures 1 to 3 As shown, in the separated state, the elastic heat-conducting plate 21 is a bent plate structure, and the middle part of the bent plate structure protrudes outward so that when the heat-conducting member 20 switches from the separated state to the heat-conducting state, the middle part of the bent plate structure moves outward. Specifically, such a configuration can ensure that when the multiple elastic heat-conducting plates 21 are elastically deformed, the elastic heat-conducting plates 21 can be deformed outward (that is, toward the side wall of the terminal socket 2) instead of inward, thereby ensuring that when the elastic heat-conducting plates 21 are deformed, they can cooperate with the side wall of the terminal socket 2 to transfer heat.

[0041] In addition, the temperature measuring structure also includes a retaining member arranged on the base 10, and the retaining member can cooperate with the secondary terminal 1 so that the heat conducting member 20 is kept in a heat conducting state, and the retaining member includes an elastic protrusion or a groove. Specifically, in the present embodiment, the retaining member includes an elastic protrusion, and a groove that cooperates with the elastic protrusion is arranged on the side wall of the terminal jack 2. When the temperature measuring structure is inserted into the terminal jack 2 and in place, the heat conducting member 20 switches to a heat conducting state and in place. At this time, the elastic protrusion is plugged and matched with the groove so that the heat conducting member 20 is kept in a heat conducting state. When the temperature measuring structure needs to be separated from the secondary terminal 1, the staff slightly pulls out the temperature measuring structure with force, and the elastic protrusion retracts and disengages from the groove, so that the heat conducting member 20 can be withdrawn from the terminal jack 2.

[0042] like Figures 1 to 3 As shown, the temperature measuring element 30 includes a temperature measuring sticker, and a plurality of indicating parts are provided on the temperature measuring sticker, and the plurality of indicating parts correspond to different temperatures. In this embodiment, the temperature measuring sticker can be a temperature-sensitive test paper, and the indicating part is in the form of a thermometer. According to different temperatures, the indicator in the indicating part moves in the thermometer to show different temperatures. In addition, in other embodiments, the indicating part can include a plurality of indicating marks, and different indicating marks correspond to different temperatures. When a certain temperature is measured, the corresponding indicating mark lights up or displays color.

[0043] like Figures 1 to 3As shown, the temperature measuring structure further includes a heat-conducting protrusion 40, which is arranged on a side of the base 10 close to the secondary terminal 1. When the heat-conducting member 20 is in a heat-conducting state, the heat-conducting protrusion 40 is heat-conductingly connected between the secondary terminal 1 and the base 10. Specifically, the heat-conducting protrusion 40 can further increase the contact area between the temperature measuring structure and the secondary terminal 1, thereby ensuring the heat transfer efficiency.

[0044] like Figures 1 to 5 As shown, the secondary terminal 1 includes a first wiring seat 3, a second wiring seat 4 and a connecting paddle 5 which are arranged at intervals. The connecting paddle 5 is movably arranged between the first wiring seat 3 and the second wiring seat 4 and can connect or disconnect the first wiring seat 3 and the second wiring seat 4. When the heat-conducting member 20 is in a heat-conducting state, the heat-conducting protrusion 40 and the connecting paddle 5 are limitedly matched so that the connecting paddle 5 remains in a state of connecting the first wiring seat 3 and the second wiring seat 4. Specifically, the heat-conducting protrusion 40 can be clamped between the connecting paddle 5 and the wiring seat, so that the connecting paddle 5 remains in a state of connecting the first wiring seat 3 and the second wiring seat 4, thereby ensuring that the function of the secondary terminal 1 is realized.

[0045] like Figure 4 as well as Figure 5 As shown, the present application also provides a secondary terminal assembly, the secondary terminal assembly of the present application includes a secondary terminal 1 and a temperature measuring structure, the secondary terminal 1 is plugged and matched with the temperature measuring structure, wherein the temperature measuring structure is the above-mentioned temperature measuring structure. The above-mentioned temperature measuring structure can effectively solve the problem that it is difficult for workers in the related technology to measure the temperature of the secondary terminal, and the secondary terminal assembly with the above-mentioned temperature measuring structure also has the above-mentioned advantages.

[0046] like Figure 4 as well as Figure 5 As shown, the secondary terminal assembly includes a plurality of secondary terminals 1 and a plurality of temperature measuring structures, the plurality of secondary terminals 1 are arranged in one-to-one correspondence with the plurality of temperature measuring structures, the plurality of secondary terminals 1 are arranged in a stacked manner, and an insulating portion 50 is arranged between the bases 10 of two adjacent temperature measuring structures. Specifically, the insulating portion 50 is arranged to avoid the situation where the bases 10 of adjacent temperature measuring structures are electrically connected. In this embodiment, the insulating portion 50 is a layered structure.

[0047] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0048] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0049] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
