Description

Technical Field

[0001] The utility model belongs to the technical field of current transmitters, and more specifically, particularly relates to a current transmitter which is easy to install. Background Art

[0002] Current transmitters are mainly used for the conversion and transmission of current signals. Current transmitters are divided into AC current transmitters and DC current transmitters. Current transmitters can directly convert the measured main circuit AC current or DC current into a DC 4~20mA standard signal output in linear proportion, and then continuously transmit it to a computer or display instrument for use in the next link.

[0003] When the current transmitter is in use, it is usually necessary to fix it on the mounting frame with bolts. When the current transmitter needs to be disassembled for maintenance, all bolts need to be removed before disassembly, which reduces work efficiency. In addition, when the wire plug hole of the current transmitter is idle, dust can easily enter the wire plug hole, affecting the use effect of the current transmitter.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a current transmitter that is easy to install is provided, in order to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 4 As shown:

[0028] The utility model provides a current transmitter which is easy to install, comprising a mounting plate 1, a card slot 2 is provided at the top of the mounting plate 1, a current transmitter body 3 is installed at the top of the mounting plate 1 near the card slot 2, a pair of first mounting seats 4 are symmetrically installed on both sides of the current transmitter body 3, one side of the first mounting seat 4 is provided with four wire insertion holes 5, a mounting slot 6 is provided inside the first mounting seat 4, a fixing mechanism is installed at the position near each wire insertion hole 5, a card block 7 is installed at the bottom end of the current transmitter body 3, a limiting slot 8 is penetrated through one side of the card block 7, a first slide groove 9 is provided on one side of the mounting plate 1, and the first slide groove 9 is connected with the card slot 2, a first slider 10 is slidably installed in the first slide groove 9, and one side of the first slider 10 extends into the card slot 2, and a pair of limiting blocks 11 are symmetrically installed on both sides of the first slider 10.

[0029] The size of the first slider 10 matches the size of the limiting groove 8 , so that the first slider 10 can be inserted into the limiting groove 8 , thereby fixing the current transmitter body 3 on the mounting plate 1 .

[0030] Among them, the limit block 11 is installed with a first compression spring 12 on one side close to the first slide groove 9, and the other end of the first compression spring 12 is connected to one side of the card slot 2. When the current transmitter body 3 is installed on the mounting plate 1, the first slider 10 is located in the limit groove 8. At this time, the first slider 10 is pushed by a pair of first compression springs 12, and its position is relatively fixed. When the current transmitter body 3 needs to be disassembled, the staff pulls the pull block 20 to disengage the first slider 10 from the limit groove 8, and the current transmitter body 3 can be removed.

[0031] Among them, the fixing mechanism includes a pair of second mounting seats 13, and the pair of second mounting seats 13 are symmetrically installed on both sides of the wire insertion hole 5. The pair of second mounting seats 13 are each provided with a second slide groove 14 on the opposite side, and a trapezoidal plate 15 is slidably installed in the pair of second slide grooves 14. The pair of trapezoidal plates 15 are each installed with rubber pads 16 at the mutually fitting positions. Through the fitting of the rubber pads 16 on the pair of trapezoidal plates 15, the trapezoidal plates 15 can block the wire insertion hole 5 to prevent dust from entering the wire insertion hole 5. At the same time, when the wire is inserted, the rubber pad 16 is deformed to facilitate fixing the line between the pair of trapezoidal plates 15.

[0032] Among them, the trapezoidal plate 15 is installed with a second compression spring 17 on one side close to the second slide groove 14, and the other end of the second compression spring 17 is connected to one side of the second slide groove 14. Since the other side of the trapezoidal plate 15 is pushed by the second compression spring 17, the pair of trapezoidal plates 15 are tightly fitted together, which can prevent the pair of trapezoidal plates 15 from being separated due to factors such as gravity.

[0033] Among them, the top of the first mounting seat 4 is provided with a third slide groove 18 just above each pair of trapezoidal plates 15, and a triangular block 19 is slidably installed in the third slide groove 18. The top of the triangular block 19 extends to the outside of the top of the first mounting seat 4, and the bottom end of the triangular block 19 is close to the top of the pair of trapezoidal plates 15. When the triangular block 19 is pressed downward, the triangular block 19 moves downward along the third slide groove 18, pushing the pair of trapezoidal blocks to squeeze the second compression spring 17 and separate from each other, so as to facilitate the insertion of the line. After releasing the triangular block 19, the second compression spring 17 is reset, pushing the pair of trapezoidal blocks to fit again, and lifting and resetting the triangular block 19.

[0034] A pulling block 20 is installed on the side of the first sliding block 10 away from the card slot 2 to facilitate pulling the first sliding block 10 .

[0035] A plurality of mounting holes are formed through the top of the mounting plate 1 to facilitate mounting the mounting plate 1 and the current transmitter body 3 on the mounting frame.

[0036] The working principle of this embodiment is as follows: the staff first uses bolts to install the mounting plate 1 on the mounting frame. At this time, the first slider 10 is located in the limiting groove 8. The first slider 10 is pushed by a pair of first compression springs 12 and its position is relatively fixed. When the current transmitter body 3 needs to be disassembled, the staff pulls the pull block 20 to disengage the first slider 10 from the limiting groove 8, and the current transmitter body 3 can be removed. When the line needs to be inserted into the wire plug hole 5, the staff presses the triangular block 19 downward, and the triangular block 19 moves downward along the third slide groove 18, pushing a pair of trapezoidal blocks to squeeze the second compression spring 17 and separate from each other, so as to facilitate the insertion of the line. After the line is inserted, the triangular block 19 is released, the second compression spring 17 is reset, pushing the pair of trapezoidal blocks to fit again, and the triangular block 19 is lifted up and reset. At this time, the rubber pad 16 is deformed to fix the line between the pair of trapezoidal plates 15.
