[0027] The utility model will be further described below in combination with the drawings and examples, but these specific implementation schemes do not limit the protection scope of the utility model in any way.
[0028] Example 1
[0029] The specific implementation manner of the utility model will be described in detail below. Figures 1-6
[0030] The multifunctional electrical interface for the missile control cabin comprises a socket and three kinds of functional plugs. The socket and the plugs are arranged and distributed in a 180-degree rotational symmetry relative to the center of the electrical interface. The symmetry design has important significance: first, the same plug can realize two different functional states through the 180-degree rotational symmetry design, effectively reducing the number of plugs and the complexity of the system; second, the symmetry design ensures the reliability of the plug-in process and avoids the possibility of incorrect plugging; finally, this design greatly simplifies the operation process and improves the use efficiency.
[0031] In the embodiment, the specific structure of the socket comprises a socket 2 and a socket PCB board 1, and a plurality of sockets 2 are fixed on the socket PCB board 1 by welding, as shown in Figures 1-2 Wherein A1 is the first power output positive pole, A2 is the power negative pole, A3 is the second power output positive pole, A4 is the third power output positive pole, A5 is the power positive pole, and A8 is the second power output negative pole. Figure 2 The electrical pins in the middle frame are connected to each other to ensure all kinds of electrical relationships, and the electrical definition design in the embodiment fully considers the requirements in various functional states: by reasonably distributing the positions of the power positive and negative poles, the electrical safety during different functional switching is ensured; the design of multiple power output groups provides independent power supply channels for different functions, effectively avoiding mutual interference between functions.
[0032] The utility model designs three different functional plugs, which are respectively used for realizing four functions:
[0033] The first is a test plug, as shown in Figure 3 The electrical relationship between the test plug and the socket, and the structure comprises a resistor R1, a light emitting diode D1, a pin 4 and a plug PCB board 3. The electrical connection of the test plug is carefully designed: the pin 4 comprises B1, B2, B3, B4, B5 and B8, and is correspondingly plugged with the corresponding socket 2. Among them, B4 and B8 are short-circuited to form a negative pole to protect the internal circuit, and this protection circuit design is crucial to the safety of the test process; B3 is connected to one end of the resistor R1, the other end of the resistor R1 and the anode of the light emitting diode D1, and the cathode of the light emitting diode D1 and B2 negative pole are connected. The setting of the light emitting diode not only serves to indicate the working state, but more importantly, provides intuitive test feedback, which is convenient for the operator to monitor the test state in real time. The setting of the resistor R1 plays a current limiting protection role, further improving the safety of the test process.
[0034] The second is a charging plug, as shown in Figure 4The electrical relationship between the charging plug and the socket includes the pins 4 and the plug PCB board 3. The pins of the charging plug include C1, C2, C3, C5 and C8, which are correspondingly inserted into the corresponding sockets 2 of the socket. The charging plug adopts a unique electrical connection mode: C1 and C5 are short-circuited to form a double-protected positive electrode of the power supply, and C2 is a negative electrode for charging; C3 and C8 are short-circuited to protect the internal circuit. The connection mode considers multiple safety protections in the charging process: first, the short-circuit of the double positive electrodes increases the reliability of the charging circuit; second, the protection circuit ensures the safety of other circuits in the charging process; and finally, the design of the entire charging circuit guarantees the stability and efficiency of the charging process.
[0035] The third is a service and launch plug, which can realize two different functional states of service and launch through a simple 180° rotation. Figure 5 The electrical relationship between the service and launch plug and the socket is that, in the service state, the service and launch plug is inserted into the socket, the pins 4 include E1, E2, E3, E4, E5 and E8, which are correspondingly inserted into the sockets A1, A2, A3, A4, A5 and A8 of the socket 2, wherein E4 is a third power supply output positive electrode and E8 is a second power supply output negative electrode for protecting the internal circuit; the rest of the pin connections have no electrical effect.
[0036] Referring to Fig. 4, Figure 6 The electrical relationship between the service and launch plug and the socket is that, when rotated by 180° into the launch state, the pins 4 include F1, F2, F3, F4, F5 and F8, which are correspondingly inserted into the sockets A1, A2, A3, A4, A5 and A8 of the socket 2. Among them, F1 and F5 are short-circuited to be the positive electrode of the power supply, F2 is the negative electrode of the power supply, F3 and F4 are short-circuited to be the power output, and F8 is the second power output negative electrode.
[0037] 1 pin and 5 pin are short-circuited to be the positive electrode of the power supply, 2 pin is the negative electrode of the power supply, 3 pin and 4 pin are short-circuited to be the power output, and 8 pin is the second power output negative electrode. The electrical relationship of the plug corresponds to the electrical relationship of the socket, and the launch function is realized.
[0038] The structural design advantage of the service and launch plug is that: on the one hand, the function switching is realized by mechanical rotation, which avoids additional electronic switch circuit, improves the reliability, and the electrical connections in the two states are completely independent, which ensures the safety of the function switching. On the other hand, the operation is simple and intuitive, which reduces the possibility of operation errors, greatly saves the space and cost, and improves the integration of the system.
[0039] The working principle and operation method of the utility model are as follows:
[0040] The implementation of the test function: after inserting the test plug, one end of the B3 connecting resistor R1, the other end of the resistor R1 and the anode of the light-emitting diode D1 are connected, the cathode of the light-emitting diode D1 and the negative pole of the B2 are connected, and the working state of the circuit can be directly observed through the light-emitting diode. During the test process, the resistor R1 plays a current limiting protection role, and the short circuit of the B4 and the B8 forms a protection circuit, thereby ensuring the safety of the test. This design not only simplifies the test process, but also improves the reliability and safety of the test.
[0041] The implementation of the charging function: after inserting the charging plug, the positive pole of the power supply formed by C1 and C5 is connected with the negative pole of C2 to form a charging circuit. Meanwhile, the short circuit of C3 and C8 forms a protection circuit, which effectively prevents abnormal conditions during the charging process and greatly improves the safety and reliability of the charging process.
[0042] The implementation of the service function: when the service launch plug is inserted, the third power supply output positive pole E4 and the second power supply output negative pole E8 protect the internal circuit. In this state, the other pins are in a safe electrical state, thereby ensuring the safety of the service process.
[0043] The implementation of the launch function: after rotating the service launch plug by 180 degrees and inserting it, the short circuit of F1 and F5 is the positive pole of the power supply, F2 is the negative pole of the power supply, the short circuit of F3 and F4 is the power supply output, and F8 is the second power supply output negative pole. By changing the electrical connection relationship, the launch function is realized. The circuit connection in this state ensures the reliable transmission of the launch signal while maintaining the safety of the circuit.
[0044] In the above embodiment, the short circuit between the pins is realized by the conductive wire or the short circuit wire on the PCB, so as to ensure reliable electrical connection.
[0045] The utility model has the following technical effects in practical application:
[0046] Through integrated design, the functions originally realized by multiple independent interfaces are integrated into one electrical interface, thereby significantly reducing the number of interfaces in the missile control cabin and reserving more installation space for other devices. Compared with the traditional multiple interface scheme, more than 50% of the installation space can be saved, and through the unified socket design, the organic unity of multiple functions is realized, and the compatibility problem between multiple independent interfaces is avoided.
[0047] Through reasonable electrical isolation design, the functions do not interfere with each other. Especially in the test function, through the cooperation of the resistor R1 and the light-emitting diode D1, reliable test function is realized, and the safety of the test process is ensured, and the setting of the protection circuit further improves the reliability of the whole system.
[0048] The 180° rotation symmetry design enables the same plug to realize two different functional states, which not only simplifies the operation process, but also reduces the training requirement of the operator. In particular, when the service and launch functions are switched, only a simple rotation of the plug is required, which greatly improves the operation efficiency.
[0049] Finally, due to the modular design, each plug can be independently maintained and replaced, and when a certain function fails, only the corresponding plug needs to be replaced, without the need to replace the entire interface system, which greatly reduces the maintenance cost and time.
[0050] The utility model is suitable for the electrical connection demand of each type missile control cabin, especially is suitable for the occasion of strict space requirement, many function demand. Through this multifunctional electrical interface, the electrical connection demand of missile control cabin in test, charging, service and launch process can be effectively solved, and the overall performance and reliability of missile control system are improved.
[0051] Through the detailed description of the above embodiments, the technical scheme of the utility model not only solves the problems in the prior art, but also brings significant technical progress, and provides a new solution for the electrical interface design of missile control cabin.
[0052] The above is only the preferred embodiment of the utility model, and does not limit the protection scope of the utility model, and any innovative improvement or replacement based on the utility model should belong to the claim category of the utility model. Meanwhile, the various parameters, materials and processes mentioned in the above embodiment are not unique, and under the premise of not deviating from the technical essence of the utility model, the ordinary skilled in the art can make various alternative choices, and these alternative solutions should be considered to fall within the protection scope of the utility model.
