Description
Technical Field
[0001] The utility model relates to the technical field of temperature measuring sensors, in particular to a temperature measuring sensor for plum blossom contacts. Background Art
[0002] In order to avoid safety accidents, it is necessary to monitor the contact temperature of electrical equipment in real time online to grasp the internal temperature status of the electrical equipment in real time, discover hidden dangers in advance, and reduce or eliminate the occurrence of thermal failures.
[0003] Existing temperature sensors need to be installed tightly on the contact piece of the contact to transfer the temperature of the contact to the sensor. The traditional installation method is generally to use a strap-style binding, that is, to bind the sensor to the outer side of the contact through a strap, but this method is not suitable for plum blossom contacts, because the equipment needs to be inspected irregularly, and the plum blossom contact will expand or tighten during the withdrawal / insertion process. This action may cause the strap fixing method to loosen, the sensor to move, and it cannot fit tightly with the contact piece, eventually causing temperature detection failure or large temperature differences.
[0004] In summary, proposing a temperature sensor for plum blossom contacts to improve the accuracy of detection results is of great significance for contact temperature detection. Utility Model Content
[0005] The utility model aims to provide a temperature measuring sensor for a plum blossom contact, comprising a conductive plate and a cable tie, wherein the cable tie and the conductive plate are enclosed to form a clamping space, and the clamping space is used to clamp a contact piece of the plum blossom contact, thereby changing the installation method of the sensor, ensuring that the sensor is not affected by the movement of the contact, and thus ensuring the accuracy of the sensor.
[0006] Because the plum blossom contact will expand or tighten during the process of withdrawal / insertion during the irregular maintenance of the equipment, the existing strap-type bundling that binds the sensor to the outer side of the contact through the strap is not suitable for the plum blossom contact. The length of the strap after bundling will not expand or contract with the deformation of the plum blossom contact. The sensor may move due to the loosening of the strap fixing method, making it impossible for the sensor to fit tightly with the contact piece, ultimately leading to inaccurate temperature detection.
[0007] The purpose of the utility model is mainly achieved through the following technical solutions:
[0008] A temperature sensor for a plum blossom contact, comprising a sensing device, a conductive plate and a cable tie, wherein the cable tie and the conductive plate are combined to form a clamping space, and the clamping space is used to clamp a contact piece of the plum blossom contact;
[0009] The conductive plate is provided with a locking device, and the two ends of the cable tie pass through the locking device, and the cable tie is connected to the conductive plate through the locking device;
[0010] The sensor device is fixed on the conductive plate.
[0011] During the adjustment of the contact, the shape and size of the contact piece will not change. Therefore, the utility model encloses the conductive plate and the cable tie to form a clamping space for clamping the contact piece of the plum blossom contact, thereby changing the fixing method of the temperature sensor suitable for the plum blossom contact. When the plum blossom contact is disassembled and assembled due to maintenance and expands or contracts, the clamping space and the clamping state of the contact piece are not affected, thereby avoiding the situation where the temperature sensor cannot be in close contact with the contact and cannot accurately measure the temperature during the maintenance of the electrical equipment.
[0012] The utility model utilizes the clamping space to clamp the contact piece, so that the cable tie and the conductive plate are in close contact with the contact piece, and the clamping relationship is not changed during the adjustment of the plum blossom contact, so that the temperature at the plum blossom contact can be accurately transmitted to the sensing device, ensuring that the sensor of the utility model can be used for a long time, reducing the cost of replacement and adjustment, and always maintaining high precision and accuracy.
[0013] Compared with the prior art in which the temperature sensor is fixed on the periphery of the plum blossom contact, the utility model fixes the temperature sensor on the contact piece, which occupies a smaller space area and can be used in narrow spaces and plum blossom contacts of different thicknesses without being restricted by the installation environment.
[0014] The locking device is used to lock the connecting tie and the conductive plate to ensure the fastening of the conductive plate and the tie, thereby ensuring that the conductive plate can be in close contact with the contact piece and will not fall off and ensuring the stability of temperature reception.
[0015] Furthermore, it also includes a shell, which is fixed on the conductive plate, and the shell and the clamping space are respectively located on two opposite or adjacent sides of the conductive plate, and the locking device is exposed outside the shell.
[0016] A housing is arranged on the other side of the conductive plate relative to the clamping space, and the sensor device is wrapped by the housing to prevent external water, oil, dust, force, etc. from affecting the performance and service life of the sensor.
[0017] The locking device is exposed outside the shell, which is convenient for adjustment during installation. The shell does not need to be opened to fix the conductive plate and the cable tie, which is convenient for observation and disassembly.
[0018] Furthermore, a side of the cable tie away from the conductive plate is in contact with the contact sheet, and the contact portion is a contact section of the cable tie, and the contact section completely covers the contact sheet.
[0019] The side of the cable tie away from the conductive plate is in contact with the contact piece, ensuring the clamping degree of the contact piece by the clamping space, so that when the cable tie and the conductive plate are locked, the tensioning force of the cable tie is mainly concentrated on the contact piece of the plum blossom contact, and will not cause damage to the copper plate.
[0020] The fitting section completely covers the contact piece, ensuring that the two side ends of the contact portion between the contact piece and the fitting section will not excessively scratch and wear the cable tie, and through a larger fitting area, the influence of the tensioning force on the contact piece is reduced.
[0021] Furthermore, the locking device includes a fixing seat with a screw hole and a screw, the fixing seat is located on the conductive plate, and the screw passes through the cable tie and is fixed on the fixing seat.
[0022] As a specific structure of the locking device, the locking device includes a fixing seat with a screw hole and a screw, the fixing seat is fixed on the conductive plate, and the cable tie is fixed to the fixing seat by screws, the structure is simple and stable, and the installation is convenient;
[0023] The size of the clamping space is adjusted by adjusting the tightening position of the screw hole and the cable tie to adapt to the contact pieces of different types of plum blossom contacts and ensure that the clamping space completely clamps the contact pieces.
[0024] Furthermore, the axis of the locking device coincides with the center line of the conductive plate.
[0025] The axis of the locking device coincides with the center line of the conductive plate, and the fixing position of the cable tie and the conductive plate is centered. The utility model is evenly stressed and can effectively prevent the conductive plate from tipping over, warping, and uneven heating.
[0026] Furthermore, the cable tie includes a plurality of through holes, and the plurality of through holes are evenly spaced along an extension direction of the cable tie.
[0027] A plurality of evenly spaced perforations are provided on the cable tie, and the height of the clamping space is adjusted by locking different perforations, thereby adjusting the tightness of the contact clamping, and the size of the clamping space can be adjusted according to different plum blossom contact models to adapt to a variety of plum blossom contacts and improve applicability;
[0028] The screw passes through the fixing seat and the cable tie at the same time, ensuring the stability and tightness of the connection between the fixing seat and the cable tie, so that the device can be used more effectively.
[0029] Furthermore, the end of the cable tie passes through the conductive plate and extends above the fixing seat, and the portion of the cable tie that is higher than the fixing seat is a rebate section, and the rebate section is attached to the surface of the fixing seat.
[0030] The end of the cable tie passes through the conductive plate and extends to the top of the fixing seat, so that the locking device is located above the conductive plate, which is convenient for disassembly and assembly operations;
[0031] The portion of the cable tie that is higher than the fixing seat is buckled back to the surface of the fixing seat. If the perforation on the cable tie is deformed, the buckled section can prevent the cable tie from moving downward as a whole, thereby loosening the clamping space on the contact piece, making the temperature detection ineffective or the temperature difference large; buckling the cable tie back can also reduce the space area of the utility model.
[0032] Furthermore, the tail end of the screw is a circular cone head with a reduced diameter.
[0033] Due to the gap between adjacent through-holes, when the clamping space completely clamps the contact piece, the screw hole on the fixing base may not correspond to the through-hole on the cable tie. The tail end of the screw is set as a round cone head, which is convenient for aligning the screw with the through-hole below the horizontal position of the screw, so as to stably fix the cable tie on the conductive plate.
[0034] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0035] 1. A conductive plate and a cable tie are provided, wherein the cable tie and the conductive plate are enclosed to form a clamping space, wherein the clamping space is used to clamp the contact piece of the plum blossom contact, thereby changing the installation method of the sensor and ensuring that the sensor is not affected by the movement of the contact, thereby ensuring the accuracy of the sensor.
[0036] 2. The end of the cable tie passes through the conductive plate and extends to the top of the fixing seat. The portion of the cable tie that is higher than the fixing seat is buckled back to the surface of the fixing seat. The buckled section can prevent the cable tie from moving downward, resulting in loose clamping of the contact piece by the clamping space, making the temperature detection ineffective or causing a large temperature difference. At the same time, buckling the cable tie back can reduce the space area of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.
[0044] Example:
[0045] like Figure 1-Figure 4 As shown, this embodiment relates to a temperature sensor for a plum blossom contact in the technical field of temperature sensors; it includes a sensing device, a conductive plate 3 and a cable tie 4, wherein the cable tie 4 and the conductive plate 3 are enclosed to form a clamping space, and the clamping space is used to clamp the contact piece of the plum blossom contact;
[0046] The conductive plate 3 is provided with a locking device 2, and both ends of the cable tie 4 pass through the locking device 2, and the cable tie 4 is connected to the conductive plate 3 through the locking device 2;
[0047] The sensor device is fixed on the conductive plate 3 .
[0048] When equipment ages or fails, it is easy to cause the temperature of equipment components to rise abnormally, resulting in a vicious cycle of temperature and contact resistance. As the temperature rise time increases, the temperature exceeds the limit and the degree of oxidation increases due to heat, which may cause accidents such as burning of busbars, contacts, damaged contacts, and power outages.
[0049] During the adjustment of the contact, the shape and size of the contact piece will not change. Therefore, the utility model encloses the conductive plate 3 and the cable tie 4 to form a clamping space for clamping the contact piece of the plum blossom contact, thereby changing the fixing method of the temperature sensor suitable for the plum blossom contact, thereby avoiding the situation where the temperature sensor cannot be in close contact with the contact and cannot accurately measure the temperature during the maintenance of the electrical equipment.
[0050] The utility model utilizes the clamping space to clamp the contact piece, so that the cable tie 4 and the conductive plate 3 are in close contact with the contact piece, and the clamping relationship is not changed during the adjustment of the plum blossom contact, so that the temperature at the plum blossom contact can be accurately transmitted to the sensing device, ensuring that the sensor of the utility model can be used for a long time, reducing the cost of replacement and adjustment, and always maintaining high precision and accuracy.
[0051] Compared with the prior art in which the temperature sensor is fixed on the periphery of the plum blossom contact, the utility model fixes the temperature sensor on the contact piece, which occupies a smaller space area and can be used in narrow spaces and plum blossom contacts of different thicknesses without being restricted by the installation environment.
[0052] The locking device 2 is used to lock and connect the cable tie 4 and the conductive plate 3 to ensure the fastening of the conductive plate 3 and the cable tie 4, thereby ensuring that the conductive plate 3 can be in close contact with the contact piece and will not fall off and ensuring the stability of temperature reception.
[0053] As a preferred solution of the above scheme, a sensor with a narrow width is used, and the widths of the cable tie 4 and the conductive plate 3 are correspondingly reduced, which can be used for the installation of a new plum blossom contact with a reinforcement ring. At the same time, it is suitable for traditional strap-type bundling, is no longer limited by the installation environment, and can be used in narrow spaces.
[0054] As a preferred implementation of the above solution, the cable tie 4 has a smooth cross-section to reduce wear caused by sharp corners.
[0055] Furthermore, it also includes a shell 1, which is fixed on the conductive plate 3, and the shell 1 and the clamping space are respectively located on two opposite or adjacent sides of the conductive plate 3, and the locking device 2 is exposed outside the shell 1.
[0056] A housing 1 is disposed on the other side of the conductive plate 3 relative to the clamping space, and the sensor device is wrapped by the housing 1 to prevent external water, oil, dust, force, etc. from affecting the performance and service life of the sensor.
[0057] The locking device 2 is exposed outside the housing 1, which is convenient for adjustment during installation. The housing 1 does not need to be opened to fix the conductive plate 3 and the cable tie 4, which is convenient for observation and disassembly.
[0058] Furthermore, the side of the cable tie 4 away from the conductive plate 3 is in contact with the contact sheet, and the contact portion is a contact section 4 - 2 of the cable tie 4 , and the contact section 4 - 2 completely covers the contact sheet.
[0059] The side of the cable tie 4 away from the conductive plate 3 is in contact with the contact piece to ensure the clamping degree of the contact piece by the clamping space. When the cable tie 4 and the conductive plate 3 are locked, the tensioning force of the cable tie 4 is mainly concentrated on the contact piece of the plum blossom contact, and no damage is caused to the copper plate.
[0060] The fitting section 4-2 completely covers the contact piece, ensuring that the two side ends of the contact portion between the contact piece and the fitting section 4-2 will not excessively scratch and wear the cable tie 4, and through a larger fitting area, the influence of the tensioning force on the contact piece is reduced.
[0061] Furthermore, the locking device 2 includes a fixing seat 2-1 with a screw hole and a screw 2-2, the fixing seat 2-1 is located on the conductive plate 3, and the screw 2-2 passes through the cable tie 4 and is fixed on the fixing seat 2-1.
[0062] As a specific structure of the locking device 2, the locking device 2 includes a fixing seat 2-1 with a screw hole and a screw 2-2. The fixing seat 2-1 is fixed on the conductive plate 3, and the cable tie 4 is fixed to the fixing seat 2-1 by the screw 2-2. The structure is simple and stable, and the installation is convenient.
[0063] The size of the clamping space is adjusted by adjusting the abutting position of the screw hole and the cable tie 4 to adapt to the contact pieces of different types of plum blossom contacts and ensure that the clamping space completely clamps the contact pieces.
[0064] As a preferred solution of the above solution, the screw 2-2 is installed on the conductive plate 3, and there is no need to find an adapter screw 2-2 during the installation process, and it can also prevent the time spent on finding the screw 2-2 after it falls off. Specifically, the conductive plate 3 is made of a copper plate and an M2 screw hole is set on it. The screw 2-2 is an M2 screw that matches the screw hole and is pre-installed in the screw hole at the factory to form an integrated product. In this way, the smaller M2 screw does not need to be held on site and then installed, thereby avoiding the situation where the screw falls off during the installation process (when used for on-site installation, it is only necessary to loosen the screw, put on the cable tie 4, and then tighten the screw. The screw is on the copper plate throughout the process, avoiding the problem of the screw falling into the equipment, which is inconvenient to operate and causes a long installation time).
[0065] Furthermore, the axis of the locking device 2 coincides with the center line of the conductive plate 3 .
[0066] The axis of the locking device 2 coincides with the center line of the conductive plate 3, and the fixing position of the cable tie 4 and the conductive plate 3 is centered. The utility model is evenly stressed and can effectively prevent the conductive plate 3 from tipping over, warping, and uneven heating.
[0067] Furthermore, the cable tie 4 includes a plurality of through holes 4 - 1 , and the plurality of through holes 4 - 1 are evenly spaced along the extension direction of the cable tie 4 .
[0068] A plurality of evenly spaced through holes 4-1 are provided on the cable tie 4. The height of the clamping space is adjusted by locking different through holes 4-1, thereby adjusting the tightness of the contact clamping. The size of the clamping space can be adjusted according to different plum blossom contact models to adapt to a variety of plum blossom contacts and improve applicability.
[0069] The screw 2-2 passes through the fixing seat 2-1 and the cable tie 4 at the same time, ensuring the connection stability and tightness of the connection between the fixing seat 2-1 and the cable tie 4, so that the device has a better use effect.
[0070] Furthermore, the end of the cable tie 4 passes through the conductive plate 3 and extends to the top of the fixing seat 2-1, and the portion of the cable tie 4 higher than the fixing seat 2-1 is a rebate section, and the rebate section is attached to the surface of the fixing seat 2-1.
[0071] The end of the cable tie 4 passes through the conductive plate 3 and extends to the top of the fixing seat 2-1, so that the locking device 2 is located above the conductive plate 3, which is convenient for disassembly and assembly operations;
[0072] The portion of the cable tie 4 that is higher than the fixing seat 2-1 is rebated to the surface of the fixing seat 2-1. If the perforation 4-1 on the cable tie 4 is deformed, the rebated section can prevent the cable tie 4 from moving downward as a whole, thereby loosening the clamping space on the contact piece, making the temperature detection ineffective or the temperature difference large; rebating the cable tie 4 can also reduce the space area of the utility model.
[0073] Furthermore, the tail end of the screw 2-2 is a circular cone head 2-3 with a reduced diameter.
[0074] Because there is a gap between adjacent through-holes 4-1, when the clamping space completely clamps the contact piece, the screw hole on the fixing seat 2-1 may not correspond to the through-hole 4-1 on the cable tie 4. The tail end of the screw 2-2 is set as a circular cone head 2-3, which is convenient for aligning the screw 2-2 with the through-hole 4-1 below the horizontal position of the screw 2-2, so as to stably fix the cable tie 4 on the conductive plate 3.
[0075] As a preferred solution of the utility model:
[0076] The screw 2-2 is an M2 machine screw;
[0077] The conductive plate 3 is made of copper plate, and openings are provided at both ends of the conductive plate 3 to accommodate the cable tie 4, and the two openings are symmetrical with respect to the conductive plate 3 itself, and the two sides of the openings are fixed seats 2-1, and the fixed seats 2-1 are provided with screw holes, and the positions of the screw holes on the two fixed seats 2-1 correspond to each other;
[0078] The cable tie 4 is a steel cable tie 4 with a width of 4 mm. The side of the cross section of the cable tie 4 is arc-shaped. Both ends of the cable tie 4 are provided with a plurality of rows of evenly spaced perforations 4-1, and each row of the perforations 4-1 is parallel to the center line of the cable tie 4.
[0079] The two ends of the cable tie 4 pass through the openings at the two ends of the conductive plate 3 respectively, so that a clamping space with the same height as the contact piece is formed between the cable tie 4 and the conductive plate 3, and the screw 2-2 is inserted into the screw hole of the fixing seat 2-1 and the through hole 4-1 of the cable tie 4. The sensor device is located between the locking device 2, and the housing 1 covers the conductive plate 3, and the locking device 2 is exposed to the outside.
[0080] It should be noted that, compared with the prior art, this solution provides a new installation method, in which the clamping space is used to clamp the smaller protruding part of the contact piece on the side of the plum blossom contact, and the contact surface is changed from the outer periphery of the original plum blossom contact to the part of one or two contact pieces on the plum blossom contact extending from the side of the contact. That is, the temperature sensor of the utility model only needs to be larger than the area where one or two contact pieces extend from the side of the contact, and the width of the cable tie 4 and the conductive plate 3 used is equivalent to the extended length of the clamped contact piece. Considering the installation environment during specific use, the preferred application is that the maximum width of this solution is limited to 15mm, and the height does not exceed 10mm, so that narrower plum blossom contacts can also be used. In summary, in this solution, the height of the clamping space is set to be the height of the contact piece, etc., so that the overall height of the utility model is low. In actual use, the height of the utility model does not exceed 1cm to prevent impact or extrusion on the equipment, and the length of the clamping space is slightly larger than the width of one or two contact pieces, so that the overall structure of the utility model is small and suitable for installation in narrow spaces.
[0081] As a specific implementation of the present invention, the overall length of the present invention is 44.1 mm, the width is 15 mm, and the height is 8 mm.
[0082] When the above scheme is used:
[0083] In the actual production process of this solution, the conductive plate 3, the locking device 2 and the housing 1 are installed as a whole, the sensor chip is placed on the conductive plate 3, and then the housing 1 is installed on the conductive plate 3, so that the housing 1 covers the sensor device and exposes the locking device 2. In actual use, it is only necessary to adjust the locking position of the cable tie 4 and the locking device 2 according to the specifications of the contact piece, and the operation is simple and convenient.
[0084] During actual use, place the conductive plate 3 on the contact piece, loosen the screw 2-2, pass the cable tie 4 through the opening and tighten it upwards, so that the bottom of the cable tie 4 is in close contact with the bottom of the contact piece, and while ensuring that the fitting section 4-2 and the contact piece are tightly squeezed against each other, tighten the screw 2-2 to fix the fixing seat 2-1 and the cable tie 4, and finally, buckle the portion of the cable tie 4 that is higher than the fixing seat 2-1 back to the surface of the fixing seat 2-1.
[0085] The utility model is easy to operate, suitable for various types of plum blossom contacts and can be installed in a narrow area, so that the plum blossom contacts are not affected by operations such as maintenance, and have relatively stable and accurate measurement results.
[0086] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
