Description

Technical Field

[0001] This utility model relates to the field of electrical energy measurement technology, and in particular to a compatible pulse sampling terminal block for the calibration of electrical energy meters. Background Technology

[0002] With the development of technology, to adapt to different application scenarios, the number of terminals in the pulse sampling terminal block is no longer limited to eight. Currently, it is possible to order the required number of terminals from the manufacturer. The terminal block mainly consists of terminals and an outer housing. The outer housing is often fixed in place with screws during use. To change the short circuit connection between the terminals, the shorting strip needs to be removed and reinstalled with a different type of shorting strip. This process is not only cumbersome, but many terminal blocks now use markings to assist with wiring. If the short circuit connection between the terminals is changed by replacing the shorting strip, the markings are not easy to change, and replacing different shorting strips requires re-integrating the terminals, which makes it difficult to redetermine the test output after integration. Moreover, when the pulse sampling terminal block is damaged, the entire block needs to be replaced, which is costly. Therefore, there is an urgent need for a compatible pulse sampling terminal block for energy meter verification to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a compatible pulse sampling terminal block for the verification of electricity meters. If the short circuit between the terminals is changed by replacing the short circuit strip, the markings are not easy to change and the terminals need to be re-integrated when changing different short circuit strips. This makes it troublesome to redetermine the integrated test output terminal. Moreover, when the pulse sampling terminal block is damaged, the whole thing needs to be replaced, which is costly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compatible pulse sampling terminal block for electricity meter calibration, comprising a fixed base, with side walls at both the front and rear ends of the fixed base, and sliding grooves for sliding installation provided on the side walls for guide rails, and a detachable sampling terminal block is provided between the side walls of the two fixed bases, the sampling terminal block being positioned between the two side walls of the fixed base by the guidance of the guide rails.

[0005] Preferably, a wire strip base is welded to the opposite surfaces of the two guide strips, and the wire strip base is welded to the bottom of the sampling terminal block.

[0006] Preferably, the leftmost ends of both guide strips are provided with limiting holes for restricting the position of the sampling terminal block. The two side walls of the fixing base are provided with threaded holes corresponding to the limiting holes, which are used to install the sampling terminal block into the corresponding threaded holes by two fixing screws and finally lock it into the corresponding limiting hole, thereby completing the limiting between the sampling terminal block and the fixing base.

[0007] Preferably, the sampling terminal block has an array of detection terminals arranged in an array. The detection terminals are connected to the sampling terminal block by detection terminal fixing screws. Similarly, the sampling terminal block has an array of the same number of shorting strip pins. Each shorting strip pin corresponds to a detection terminal. The shorting strip pin is connected to the mounting base by shorting strip fixing screws. The end of each detection terminal that is away from the shorting strip pin is electrically connected to a detection terminal wire.

[0008] Preferably, the shorting bar pins arranged in an array are wrapped together by the shorting bar body and positioned on the outside of the sampling terminal block.

[0009] Preferably, the sampling terminal block has an array of strip-shaped holes, and all of the arrayed strip-shaped holes are located at the highest point above the fixed base.

[0010] Preferably, the sampling terminal block has labels arranged in the same array, and the labels in the array correspond one-to-one with the wires of the detection terminal.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This compatible pulse sampling terminal block for energy meter calibration allows for disassembly of the sampling terminal block on the mounting base. This simplifies the process for customers when different wiring methods are required, or when the sampling terminal block is damaged and needs replacement, simply by removing the mounting screws. This simplifies the process for customers when different short-circuit connection methods necessitate changing the connection between the sampling terminal block and the short-circuit bar. Furthermore, when the sampling terminal block is damaged, only the sampling terminal block needs to be replaced, resulting in lower replacement costs compared to the original integrated terminal block.

[0013] 2. The compatible pulse sampling terminal block used for the calibration of this energy meter has different output effects of the detection terminal wires due to the different connection methods between the shorting bar pins and the fixed base. At present, due to the large number of detection terminal wires, the operation is difficult for the staff. By affixing labels to the label strip to remind the user of the output effect of the corresponding detection terminal wire, the difficulty of using this terminal block is reduced.

Detailed Implementation

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a compatible pulse sampling terminal block for electricity meter calibration, comprising: a fixed base 2, with side walls at both ends of the fixed base 2, and sliding grooves 1 for sliding installation of guide strips 10 on each side wall, and a detachable sampling terminal block 8 between the two side walls of the fixed base 2, the sampling terminal block 8 being arranged between the two side walls of the fixed base 2 by the guidance of the guide strips 10.

[0025] A wire base 11 is welded to the opposite face of the two guide bars 10, and the wire base 11 is welded to the bottom of the sampling terminal block 8.

[0026] The leftmost ends of the two guide bars 10 are provided with limiting holes 9 for limiting the position of the sampling wiring strip 8. The two side walls of the fixing base 2 are provided with threaded holes 7 corresponding to the limiting holes 9, which are used to install the corresponding threaded holes 7 by two fixing screws 6 and finally lock them into the corresponding limiting holes 9, thus completing the limiting between the sampling wiring strip 8 and the fixing base 2.

[0027] By setting the sampling terminal block 8 to be detachable from the fixed base 2, when it is necessary to replace the sampling terminal block 8 with a different wiring method or when the sampling terminal block 8 is damaged and needs to be replaced, the sampling terminal block 8 can be replaced simply by removing the fixing screw 6. This simplifies the operation for customers in actual work when different short-circuit connection methods of the terminal block require changing the connection method of the sampling terminal block 8 and the short-circuit bar. At the same time, when the sampling terminal block 8 is damaged, only the sampling terminal block 8 needs to be replaced, which is cheaper than the original integrated terminal block.

[0028] The sampling terminal block 8 has a series of detection terminal heads 13 arranged in an array. The detection terminal heads 13 are connected to the sampling terminal block 8 by detection terminal head fixing screws 15. Similarly, the sampling terminal block 8 has an array of the same number of shorting strip pins 3. The shorting strip pins 3 correspond one-to-one with the detection terminal heads 13. The shorting strip pins 3 are connected to the fixing base 2 by shorting strip fixing screws 12. The end of the detection terminal head 13 facing away from the shorting strip pins 3 is electrically connected to a detection terminal head wire 14.

[0029] The shorting bar pins 3 arranged in the array are wrapped together by the shorting bar body 4 and placed on the outside of the sampling terminal block 8.

[0030] The sampling terminal block 8 has an array of strip holes 16, all of which are located at the highest point above the fixed base 2.

[0031] The sampling terminal block 8 has a similar array of label strips 5, and the array of label strips 5 corresponds one-to-one with the detection terminal head wires 14.

[0032] When it is necessary to disassemble and replace the sampling terminal block 8;

[0033] First, the fixing screw 6 is moved by an external tool to disengage from the corresponding threaded hole 7 and the limiting hole 9. Then, the sampling terminal block 8 is moved by an external force. The movement of the sampling terminal block 8 causes the cable base 11 to move. The movement of the cable base 11 causes the two guide bars 10 to move out of the corresponding sliding groove 1, thus completing the disassembly of the sampling terminal block 8.

[0034] Secondly, the new sampling terminal block 8 is driven to move by an external force. The movement of the sampling terminal block 8 causes the two corresponding limiting holes 9 to move until they coincide with the corresponding threaded holes 7. Then, the fixing screw 6 enters the interior of the limiting hole 9 through the threaded hole 7.

[0035] When it is necessary to replace the shorting bar;

[0036] First, the shorting bar fixing screw 12 is removed by external force. Then, the shorting bar body 4 is moved by external force. The movement of the shorting bar body 4 causes the shorting bar pin 3 to move away from the sampling terminal block 8. After that, a new shorting bar is replaced and placed in the position of the shorting bar fixing screw 12. Then, the shorting bar fixing screw 12 is fixed back in its original position.

[0037] The different connection methods between the shorting bar pin 3 and the fixed base 2 result in different output effects of the detection terminal head wire 14. Currently, due to the large number of detection terminal head wires 14, the operation is difficult for staff. By attaching labels to the label strip 5 to remind users of the output effect of the corresponding detection terminal head wire 14, the difficulty of using the terminal block is reduced.

[0038] The working principle of this utility model can be summarized as follows:

[0039] When it is necessary to disassemble and replace the sampling terminal block 8;

[0040] First, the fixing screw 6 is moved by an external tool to disengage from the corresponding threaded hole 7 and the limiting hole 9. Then, the sampling terminal block 8 is moved by an external force. The movement of the sampling terminal block 8 causes the cable base 11 to move. The movement of the cable base 11 causes the two guide bars 10 to move out of the corresponding sliding groove 1, thus completing the disassembly of the sampling terminal block 8.

[0041] Secondly, the new sampling terminal block 8 is driven to move by an external force. The movement of the sampling terminal block 8 causes the two corresponding limiting holes 9 to move until they coincide with the corresponding threaded holes 7. Then, the fixing screw 6 enters the interior of the limiting hole 9 through the threaded hole 7.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
