Description

Technical Field

[0001] The utility model relates to the technical field of circuit connection, in particular to a voltage conversion device with a circuit connection protection structure. Background Technique

[0002] Voltage / current conversion, i.e., V / I conversion, is to convert the input voltage signal into a current signal that satisfies a certain relationship. The converted current is equivalent to a constant current source with adjustable output, and its output current should be able to remain stable without changing with the load. Generally, the voltage-current conversion circuit is realized in the form of negative feedback, which can be current-series negative feedback or current-parallel negative feedback, and is mainly used in industrial control and many sensor applications.

[0003] In a circuit system, a voltage conversion device is often connected to the circuit. The connection of the voltage conversion device is carried out by means of wire connection, that is, the wire extending from the inside of the voltage conversion device is connected to the external wire, or the external wire is directly connected to the wiring terminal on the voltage conversion device. The stability of the circuit connection of the voltage conversion device depends on the magnitude of the traction force at both ends of the wire. When the traction force is too large, it is easy to cause the circuit connection to be disconnected, resulting in the voltage conversion device being unable to be stably connected to the circuit, and the connection of electrical equipment often appears unstable, resulting in the problem of virtual connection of the circuit.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a voltage conversion device with a line connection protection structure as Figures 1 to 4 shown, which includes a voltage conversion device 1. A first connecting wire 2 is arranged inside the voltage conversion device 1. The first connecting wire 2 extends to the outside of the voltage conversion device 1. One end of the first connecting wire 2 away from the voltage conversion device 1 is connected to a second connecting wire 3. A connecting belt 4 is installed at the bottom of the voltage conversion device 1. An operation hole 5 is formed in the connecting belt 4. A fastening assembly 6 for limiting the first connecting wire 2 and the second connecting wire 3 is installed in the operation hole 5;

[0022] The voltage conversion device 1 is connected to other devices with which the line is connected through the connecting belt 4 to prevent the device from being pulled by external forces. The distance of the connecting belt 4 limits the first connecting wire 2 and the second connecting wire 3 from being disconnected at the connection position due to being pulled by external forces. At the same time, by using the fastening assembly 6, the first connecting wire 2 and the second connecting wire 3 are fixedly connected to the connecting belt 4, which can ensure the protection of the connecting belt 4 for the connection part of the first connecting wire 2 and the second connecting wire 3. Even in the case where the connecting belt 4 is separated from the voltage conversion device 1, the connection part is protected to ensure the circuit connection.

[0023] The fastening assembly 6 includes a clamping member 61. The clamping member 61 is sleeved outside the first connecting wire 2 and the second connecting wire 3. One end of the clamping member 61 penetrates through the operation hole 5 and is threadedly connected with a fastening nut 62. By using the threaded connection between the fastening nut 62 and the clamping member 61, it is convenient to limit the first connecting wire 2 and the second connecting wire 3 through the clamping member 61. Then, by the clamping member 61 penetrating through the operation hole 5, the first connecting wire 2 and the second connecting wire 3 are stably installed on the connecting belt 4.

[0024] The clamp member 61 includes two groups of bolt columns 611. One end of each bolt column 611 is connected with a flexible connecting rope 612. The flexible connecting rope 612 is located outside the first connecting wire 2 and the second connecting wire 3. The bolt columns 611 pass through the operation holes 5 and are threadedly connected with fastening nuts 62. Through the setting of the structure of the clamp member 61, the bolt columns 611 can be connected with the fastening nuts 62 to tighten the flexible connecting rope 612, which is convenient for limiting the first connecting wire 2 and the second connecting wire 3. At the same time, the setting of the flexible connecting rope 612 can better fit wires of different sizes and increase the contact area.

[0025] One end of the connecting belt 4 is provided with a first mounting hole 7. The end of the connecting belt 4 far from the first mounting hole 7 is successively provided with second mounting holes 8. An installation bolt 9 is movably arranged in the first mounting hole 7. The installation bolt 9 passes through the first mounting hole 7 and is threadedly connected with the voltage conversion device 1. Through the setting of the first mounting hole 7 and the second mounting holes 8, it is convenient to use the installation bolt 9 to connect the two ends of the connecting belt 4 with the voltage conversion device 1 and other devices respectively. At the same time, the distance between the voltage conversion device 1 and other devices can be adjusted according to the length of the connecting wire through the position of the second mounting holes 8.

[0026] A protective pad 10 is clamped outside the flexible connecting rope 612. A groove that fits the first connecting wire 2 and the second connecting wire 3 is provided on one side of the protective pad 10. Through the setting of the protective pad 10, the friction between the clamp member 61 and the first connecting wire 2 and the second connecting wire 3 is increased, preventing the first connecting wire 2 and the second connecting wire 3 from sliding in the clamp member 61 and making it impossible to limit the first connecting wire 2 and the second connecting wire 3 with the clamp member 61 and the fastening nut 62.

[0027] A heat shrinkable film sleeve 11 is sleeved outside the first connecting wire 2 and the second connecting wire 3. The heat shrinkable film sleeve 11 is located at the connection of the first connecting wire 2 and the second connecting wire 3. Through the setting of the heat shrinkable film sleeve 11, it is convenient to protect the connection of the first connecting wire 2 and the second connecting wire 3 and prevent the connection from being exposed.

[0028] Each set of fastening components 6 includes two clamp members 61. Through the setting of the number of clamp members 61 in the fastening components 6, it is convenient to use the two groups of clamp members 61 to limit and fix the first connecting wire 2 or the second connecting wire 3 to ensure the stability of the connection.

[0029] A support plate 12 is threadedly connected to the outside of the bolt column 611. The support plate 12 and the fastening nut 62 are located on the upper and lower sides of the connecting belt 4. Through the setting of the support plate 12, it is avoided that the connecting belt 4 is too soft, resulting in the fastening nut 62 being unable to stably fix the connecting belt 4 with the bolt column 611.

[0030] During specific use, after connecting the first connecting wire 2 and the second connecting wire 3, move the heat shrinkable sleeve 11 to the connection point, and then heat the heat shrinkable sleeve 11 to make it shrink and fit on the outer side of the connection between the first connecting wire 2 and the second connecting wire 3. Then, use the mounting bolt 9 to pass through the first mounting hole 7 to install the connecting band 4 on the outer side of the voltage conversion device 1. Subsequently, pass the two groups of bolt columns 611 through the operation holes 5 from both sides of the first connecting wire 2 or the second connecting wire 3, and then thread the fastening nut 62 onto the bolt column 611, with the flexible connecting rope 612 located on the outer sides of the first connecting wire 2 and the second connecting wire 3. Then, place the protective pad 10 on the outer side of the flexible connecting rope 612 to increase the contact area, adjust the position of the support plate 12, and then pull out the excess part of the first connecting wire 2 or the second connecting wire 3 from between the two groups of clamp members 61, and then lock the clamp members 61 to stably install the first connecting wire 2 and the second connecting wire 3 on the outer side of the connecting band 4. Use the connecting band 4 to protect the first connecting wire 2 and the second connecting wire 3 to prevent them from being pulled and disconnected by external forces.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
