Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of mining technology, and in particular to an adapter for an intrinsically safe lower computer used in mining. Background Art
[0002] Mine Intrinsic Safety (MIS) slave computers are intrinsically safe electrical equipment specifically designed for use underground in coal mines. In coal mining operations, these slave computers are often used as the terminal end of conveyor belt control systems, providing communication along the conveyor line, emergency stop and lockout functions, and connection to sensors for deviation protection and longitudinal tear protection.
[0003] In the prior art, the expansion of the tunneling working face necessitated the continuous installation of interlocking cables, loudspeakers, and emergency stop interlocks to improve the control system. Each time a new interlocking cable was installed, the original interlocking cable plug had to be removed from the slave computer. However, the pins in the slave computer's seven-pin socket were relatively thin. When the plug was re-inserted, if the docking position was incorrect or there was interference from debris such as coal slime, the pins could break without proper care. This damaged the intrinsically safe slave computer and rendered it unusable, resulting in economic losses and a certain impact on normal production operations. Utility Model Content

[0022] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0023] In this disclosure, unless otherwise indicated, directional terms such as "inner" and "outer" generally refer to the inner and outer positions of the relevant component relative to the outline in actual use. In addition, the terms "first" and "second" and the like are used in this disclosure to distinguish one element from another and do not convey order or importance.
[0024] Reference Figure 1 and Figure 2 The embodiment of the present disclosure provides an adapter for a mine intrinsically safe lower computer, comprising a sleeve 10, a socket 20 and a plug 30. Figure 1 and Figure 2 As shown, the interior of the sleeve 10 is hollow, with its ends removably connected to a socket 20 and a plug 30, respectively. The socket 20 is provided with multiple pins 21 for connecting to the output port of the lower computer, and the plug 30 is provided with multiple jacks 31 for connecting cable connectors. A connecting wire 40 is provided between the socket 20 and the plug 30 for transmitting signals between the socket 20 and the plug 30. The connecting wire 40 can be installed inside the sleeve 10.
[0025] In the above embodiment, the sleeve 10 serves as a connecting structure, which can be respectively connected to the socket 20 plugged into the output port of the lower computer and the plug 30 plugged into the cable connector, forming a signal adapter located between the lower computer and the cable, to replace the connection method of directly inserting the cable connector into the output port of the lower computer. In application scenarios where the cable needs to be plugged in and out of the lower computer multiple times, the adapter can protect the pins of the output port of the lower computer from deformation or breakage.
[0026] Through the above technical solution, the socket 20 and the plug 30 adapted for the output port of the intrinsically safe lower computer for mining are assembled together using the sleeve 10. When the socket 20 is connected to the output port of the lower computer and the plug 30 is connected to the locking wire cable connector respectively, the output port of the lower computer can be protected. The solution has the advantages of flexible use, good applicability, low cost, and can effectively reduce equipment losses caused by physical damage to the pin 21 during the plugging and unplugging process.
[0027] According to some embodiments, Figure 2 As shown, the socket 20 may include a screw-on end 22 having an external thread. Accordingly, the sleeve 10 may have an internal thread at one end near the socket 20, and the sleeve 10 may be threadedly connected to the screw-on end 22 of the socket 20. In this embodiment, the socket 20 is threadedly connected to one end of the sleeve 10 via the screw-on end 22, providing a stable connection and easy disassembly. When the connecting wire 40 on one side of the socket 20 needs to be inspected, repaired, or replaced, the socket 20 and sleeve 10 can be separated by simply twisting them in opposite directions. Of course, the socket 20 and sleeve 10 can also be assembled and disassembled using other appropriate methods, or by providing external threads on the sleeve 10 and internal threads on the socket 20. These embodiments will not be described in detail here.
[0028] For example, the socket 20 may further include a first plug end 23, such as Figure 2 As shown, the first plug end 23 can be recessed inward to form a cavity 24, and the pin 21 can be axially arranged in the cavity 24, and the pin 21 does not extend out of the cavity 24, so that the socket 20 and the output port of the lower computer can be connected inside the cavity 24. When the two are connected, at least a portion of the output port of the lower computer can be enclosed by the first plug end 23, preventing the base from being exposed to the outside and being subjected to impact or other vulnerable forms of damage after the connection, thereby forming an effective protection for the output port of the lower computer. At the same time, the pin 21 can always remain in the state of being located inside the cavity 24 when the socket 20 is not connected, and can also prevent the socket 20 from being deformed or broken due to conventional collisions or other forms of external impact. Physical damage such as breakage of the pin 21 can also be caused.
[0029] In some embodiments, as Figure 2 As shown, an annular stopper 25 is provided on the inner wall of cavity 24. This is used to engage with the output port of the lower computer when the socket 20 is plugged in, preventing the socket 20 from easily detaching after being connected to the output port of the lower computer. Furthermore, when the stopper 25 engages with the output port of the lower computer, it forms an annular sealing band, further enclosing the junction between the socket 20 and the output port of the lower computer within cavity 24. This effectively prevents impurities such as dust, dirt, and moisture from invading the junction and corroding the pins 21 or clogging the output port of the lower computer. This provides excellent protection for the junction in the harsh working environment of mines.
[0030] According to some embodiments, Figure 2 As shown, the plug 30 may include a butt end 32, and the sleeve 10 may be provided with a mounting groove 11 at one end near the plug 30, which is adapted to the shape of the butt end 32 and is used to accommodate the butt end 32. In this embodiment, the plug 30 can be simply assembled between the butt end 32 and the receiving groove 11 of the sleeve 10, which is convenient for installation and easy disassembly, making it easy to change the model of the plug 30.
[0031] For example, Figure 1 and Figure 2 As shown, a through hole 12 can be opened on the groove wall of the mounting groove 11, and a threaded hole 33 can be opened in the radial direction on the outer wall of the docking end 32, wherein the threaded hole 33 can be configured to be opposite to the opening of the through hole 12 after the docking end 32 is inserted into the mounting groove 11, so that the plug 30 can be fixedly bolted to the sleeve 10 by the bolt 13.
[0032] It should be noted that the present disclosure does not impose any specific restrictions on the number and location of through-holes 12 and threaded holes 33, nor on the size or type of bolts 13. It is only necessary to ensure that the through-holes 12 and threaded holes 33 are of compatible size and that the bolts 13 can securely secure the plug 30 and the sleeve 10 relative to each other through the through-holes 12 and threaded holes 33, thereby preventing them from easily disengaging. Furthermore, the two threaded holes 33 and the opposing through-holes 12 shown in the accompanying drawings are merely one possible arrangement provided by the present disclosure and are not intended to be exclusive. These arrangements can be adjusted based on actual installation conditions and are not detailed here.
[0033] In some embodiments, the plug 30 may further include a second plug end 34, such as Figure 2 As shown, the second plug end 34 can be configured as a tapered shape with a diameter gradually decreasing from the mating end 32 toward the direction away from the sleeve 10, and the insertion hole 31 can be axially disposed within the second plug end 34. By reducing the volume of the plug 30 and designing the second plug end 34 as a tapered structure, the plug 30 and the cable connector can be easily plugged in and out, making interference less likely.
[0034] For example, Figure 2 As shown, the outer wall of the second plug end 34 may be provided with a positioning ring 35, which is used to fit against the cable interface to seal the second plug end 34 when the plug 30 is plugged into the cable. In this embodiment, after the plug 30 is inserted into the cable connector and fully engaged, the positioning ring 35 can abut against the edge of the cable interface or engage with the inner wall of the cable interface. It can cooperate with the tapered second plug end 34 to form a closed space within the cable connector to prevent impurities such as dust, dirt, or water vapor from invading the junction between the two, corroding the cable connector or clogging the jack 31, affecting the subsequent plugging and unplugging process, thereby providing good dust protection.
[0035] According to some embodiments, the socket 20 may be a seven-pin socket with seven pins 21 to match the shape of the output port of the lower computer. The plug 30 may be a seven-pin plug with seven jacks 31 to match the shape of the cable connector. The pins 21 may be selectively connected to the jacks 31 via corresponding connecting cables 40. In this embodiment, any pair of connected pins 21 and jacks 31 may be assigned a common identifier to facilitate connection. Furthermore, the identifiers between multiple pairs of pins 21 and jacks 31 may be arranged in sequence, facilitating the corresponding transmission of interface signals within the same group and facilitating troubleshooting of damaged pins 21, connecting cables 40, or jacks 31 in the event of a fault.
[0036] In some embodiments, the sleeve 10 may also be provided with a cable channel to facilitate the separate storage of the multiple connecting cables 40 connected between the socket 20 and the plug 30. This prevents the connecting cables 40 from shaking or getting tangled within the sleeve 10 after the socket 20 and the plug 30 are assembled with the sleeve 10, thereby improving the overall stability of the adapter. At the same time, the multiple connecting cables 40 can also be stored using simple tape wrapping or wire bundling to secure the multiple connecting cables 40 to each other. The present disclosure does not limit the specific storage and fixing method, and it can be adaptively adjusted according to the actual installation situation of the adapter. It will not be described in detail here.
[0037] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0039] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
