Description

Technical Field

[0001] This invention belongs to the field of small-space wiring technology, specifically relating to a multi-line wiring structure based on small space, and particularly to a wiring structure built into a firing mechanism. It can realize reliable and convenient multi-line wiring in a small space containing moving parts, and is suitable for products such as trainers that need to simulate the actual firing mechanism and realize the acquisition and transmission of action electrical signals. It can also be extended to small-space wiring scenarios for other types of firing mechanisms. Background Technology

[0002] In the research and development and production of training equipment, in order to achieve simulation of the actual firing mechanism, it is necessary to simulate the appearance and operational requirements of the actual firing mechanism. Simultaneously, the actions of the firing mechanism, such as latching, safety activation / deactivation, and firing, need to be collected as electrical signals and transmitted to an internal computer for recognition and processing. To achieve this function, moving parts such as triggers, as well as microswitches and wires for signal acquisition, need to be installed inside the firing mechanism. The wires alone require three paths (one each for the latching switch, trigger, and safety), totaling six wires.

[0003] Currently, the following technical pain points are commonly found in the internal wiring scenarios of small-space devices such as firing mechanisms and small control modules:

[0004] 1. The internal space of the equipment is small, and it is difficult to arrange multiple wires (such as trigger wires, fuse wires, and hanging switch connection wires) in an orderly manner. This can easily lead to wires becoming tangled and piled up messily, affecting the neatness of the internal structure and ease of maintenance.

[0005] 2. During equipment operation, the conductors need to move back and forth, rotate and other displacement operations in coordination with the components. The existing wiring method lacks an effective limiting structure, which can easily lead to uncontrolled conductor displacement, pulling and breaking, and affecting the stability of equipment operation.

[0006] 3. When wires are kept in a small space for a long time, the insulation layer is easily scratched when they come into contact with the edges of components and structural gaps, which may cause safety hazards such as short circuits and poor contact. At the same time, the excess length of the wires has no reasonable storage space, which further occupies the limited space inside the equipment and exacerbates the problem of messy wiring.

[0007] Due to the limited internal space of the firing mechanism and the presence of movable parts, traditional wiring methods have many drawbacks: most methods use wire clips, tape, or cotton thread to directly fix the wires to the inner wall of the firing mechanism. This not only makes disassembly and maintenance extremely inconvenient, but also requires disassembling the fixing structure when it is necessary to repair the wires or replace parts, which is time-consuming and laborious. At the same time, the wires fixed to the inner wall cannot be effectively isolated from the moving parts. During the firing mechanism's operation, the wires are prone to interference and friction with the moving parts. Long-term use will cause the wire sheath to wear and break, which will lead to signal transmission failure and affect the normal use of the trainer.

[0008] To address the aforementioned issues, there is currently no dedicated cabling structure in the industry. Conventional cable management methods can only achieve simple wire restraint and cannot simultaneously solve the three core problems of orderly arrangement, precise positioning, and wire protection in small spaces. Therefore, there is an urgent need for a multi-line cabling structure that is suitable for small spaces. By optimizing the layout of components to expand the usable internal space, effective isolation between wires and moving parts can be achieved, while simplifying the disassembly and assembly process, facilitating inspection and maintenance, and meeting the cabling requirements of the trainer firing mechanism. Summary of the Invention

[0009] I. Purpose of the Invention

[0010] The purpose of this invention is to overcome the shortcomings of existing technologies in the small space wiring of firing mechanisms, such as easy wear and tear of wires, inconvenience of disassembly and assembly, and easy interference with moving parts. The invention designs a multi-line wiring structure based on a small space. This structure is built into the firing mechanism and can realize reliable multi-line wiring in a narrow space containing moving parts, avoiding interference and wear between wires and moving parts. At the same time, it is easy to disassemble, inspect and maintain, meeting the requirements of training equipment products for the shape of the firing mechanism, operation simulation and signal transmission reliability, and can be extended to other types of firing machines.

[0011] II. Technical Solution

[0012] To achieve the above objectives, the present invention provides a multi-line wiring structure based on a small space, which is built into the firing mechanism and consists of a middle section tube (1), a hanging switch (2), a hanging switch base (3), a wire tube (4), a hanging body (5), a firing mechanism connector (6), a firing mechanism spring (7), a rubber ring (8), a support frame (9), a trigger wire (10), a safety wire (11), a screw plug (12), and a firing mechanism body (13).

[0013] The conduit (4), serving as the core component for the protection and guidance of the wire, is positioned at the central axis of the firing mechanism, passing through and through the movable firing body (5). When the firing body (5) moves, the conduit (4) remains fixed, ensuring no relative friction between the wire and the firing body (5). The conduit (4) is made of insulating and wear-resistant material, effectively isolating the wire from external moving parts, preventing wire wear, and preventing short circuits between wires.

[0014] The power switch (2), trigger wiring (10), and fuse wiring (11) are each equipped with two wires, for a total of six wires, all of which are threaded into the conduit (4) for centralized protection and wiring. The power switch (2) is located on the side of the conduit (4), and an opening with a diameter matching the wire is provided in the middle of the conduit (4). The wire of the power switch (2) is threaded into the conduit (4) through this opening, ensuring that the wires are arranged compactly and do not occupy extra space.

[0015] The trigger wire (10) and the fuse wire (11) adopt a segmented connection design. They are connected to the corresponding colored wires inside the firing mechanism (13) through connectors. The connectors adopt a foolproof design to effectively avoid wiring errors. After connection, the trigger wire (10) and the fuse wire (11) are inserted into the wire tube (4) from the front end of the wire tube (4). This segmented design greatly simplifies the wire disassembly and assembly process and facilitates later inspection and maintenance.

[0016] The excess length of the trigger wire (10) and the safety wire (11) is placed inside the cavity of the support frame (9). The support frame (9) is a hollow structure with optimized cavity size to accommodate the excess wire, while ensuring that the trigger and safety do not touch the wire during operation, further avoiding interference and wear of the wire.

[0017] The support frame (9) and the rubber ring (8) are used together to fix one end of the wire tube (4): the rubber ring (8) is sleeved on the front end of the wire tube (4), and the front end of the wire tube (4) passes through the rubber ring (8) and presses the support frame (9) tightly. The rubber ring (8) plays a role in buffering, sealing and anti-slip, and enhances the fixing stability of the wire tube (4). The front end of the support frame (9) is provided with a boss, which cooperates with the groove on the firing mechanism connector (6). This can effectively prevent the support frame (9) from rotating and avoid damage to the wire due to rotation squeezing the wire. At the same time, there is no need to process stepped holes in the deep hole of the firing mechanism connector (6), which solves the relevant process problems and reduces the manufacturing cost.

[0018] The rear end of the conduit (4) passes through the wall switch base (3), and the conduit (4) is limited by the limiting surface fixing structure: the limiting surface fixing structure is an annular limiting platform provided on the outer side of the rear end of the conduit (4), which abuts against the step on the inner wall of the wall switch base (3). This can both restrict the rotation of the conduit (4) and prevent the conduit (4) from moving backward, ensuring the overall position stability of the conduit (4) and guaranteeing the reliability of the wiring.

[0019] III. Beneficial Effects of the Invention

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. Achieve reliable wiring in small spaces and avoid wire wear: By setting up a conduit to centrally protect 6 wires, the conduit is isolated from moving parts. When the mounting body and other moving parts move, the wires are located inside the conduit and will not interfere with or rub against each other. This effectively avoids wear and breakage of the wire sheath, ensures the reliability of signal transmission, and reduces the failure rate.

[0022] 2. Convenient disassembly and maintenance, easy to test: The wires are connected by segmented connectors, and the trigger wires and fuse wires can be quickly disassembled and assembled through the connectors without disassembling the entire firing mechanism; excess wire length is placed in the cavity of the support frame, which does not affect the movement of parts, and at the same time facilitates the later wire testing and maintenance, greatly improving work efficiency.

[0023] 3. Optimize structural design and reduce manufacturing difficulty: By cooperating with the support frame boss and the firing mechanism connector groove, the support frame rotation is prevented from squeezing the wire. At the same time, there is no need to process stepped holes in the deep hole of the firing mechanism connector, which simplifies the processing technology, reduces manufacturing costs, and improves production efficiency.

[0024] 4. Meets simulation requirements and has strong versatility: The wiring structure is built into the firing mechanism, which does not affect the appearance and operation of the firing mechanism, perfectly matching the simulation requirements of the trainer for the actual firing mechanism; at the same time, the core structures such as the wire tube and support frame can be applied to other types of firing machines, achieving multi-scenario adaptation and strong versatility.

[0025] 5. Compact structure and high space utilization: By optimizing the layout of components, the wires are concentrated in the wire tube at the central position, and the excess wires are stored in the cavity of the support frame, making the most of the narrow space inside the firing mechanism and achieving compact wiring of multiple lines without affecting the normal movement of internal moving parts.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can understand it.

[0031] This invention provides a multi-line wiring structure based on a small space, built into the firing mechanism, and consists of a central tube (1), a trigger switch (2), a trigger switch base (3), a wire tube (4), a firing mechanism body (5), a firing mechanism connector (6), a firing mechanism spring (7), a rubber ring (8), a support frame (9), a trigger wire (10), a safety wire (11), a screw plug (12), and a firing mechanism body (13). The wire tube (4) is located at the central axis of the firing mechanism, passing through and through the movable firing mechanism body (5). The trigger switch (2), trigger wire (10), and safety wire (11) each have two wires, for a total of six wires, all of which are inserted into the wire tube (4). The trigger switch (2) is arranged on the side of the wire tube (4), and its wires are inserted from the opening in the middle of the wire tube (4). Insert; the trigger wire (10) and the safety wire (11) are respectively connected to the corresponding colored wires inside the firing mechanism body (13) through the connector, and are inserted into the inside of the wire tube (4) from the front end of the wire tube (4); the support frame (9) and the rubber ring (8) cooperate to fix one end of the wire tube (4), the front end of the support frame (9) is provided with a boss, which cooperates with the groove on the firing mechanism connector (6); the front end of the wire tube (4) passes through the rubber ring (8) and presses the support frame (9), and the rear end passes through the hanging switch seat (3), and the wire tube (4) is restricted from rotating and moving backward by the limiting surface fixing structure; the trigger wire (10) and the safety wire (11) are connected to the corresponding wires inside the firing mechanism body (13) through the connector, and the wires of the reserved length of the two are placed inside the cavity of the support frame (9).

[0032] The support frame (9) is a hollow cavity structure. Its cavity size is compatible with the wires of the reserved length of the trigger wire (10) and the safety wire (11). The inner wall of the cavity is smooth to avoid scratching the wires.

[0033] The limiting surface fixing structure is an annular limiting platform provided on the outer side of the rear end of the wire tube (4). The annular limiting platform abuts against the inner wall step of the hanging switch seat (3) to realize the rotational limiting and axial limiting of the wire tube (4).

[0034] The rubber ring (8) is made of silicone rubber. Its compression is adapted to the travel of the conduit (4). The rubber ring (8) fits into the connection gap between the conduit (4) and the support frame (9), while providing axial preload, buffering and sealing, and enhancing the fixation stability of the conduit (4).

[0035] The conduit (4) is made of insulating and wear-resistant material. The conduit (4) has a wire distribution groove at the opening in the middle. Six wires are arranged along the distribution groove. Its inner diameter is matched with the total cross-sectional area of ​​the six wires to ensure that the wires can be smoothly inserted without being squeezed.

[0036] The opening size in the middle of the conduit (4) is matched with the wire diameter of the hanging switch (2), and the edge of the opening is chamfered to avoid wear on the outer sheath of the wire.

[0037] The assembly and wiring process for each component is as follows:

[0038] First, complete the fixed assembly of the wire tube (4): put the rubber ring (8) on the front end of the wire tube (4), pass the front end of the wire tube (4) through the rubber ring (8), and press the support frame (9) so that the boss at the front end of the support frame (9) is embedded in the groove of the firing mechanism connector (6) to achieve the positioning of the support frame (9) and prevent it from rotating; then pass the rear end of the wire tube (4) through the firing switch seat (3) so that the annular limiting platform at the rear end of the wire tube (4) abuts against the step on the inner wall of the firing switch seat (3) to complete the rotation and axial limiting of the wire tube (4) and ensure that the wire tube (4) is located in the central axis position of the firing mechanism and is fixed reliably.

[0039] Next, arrange and connect the wires: install the on-hook switch (2) at the preset position on the side of the wire tube (4), insert the two wires of the on-hook switch (2) into the inside of the wire tube (4) through the opening in the middle of the wire tube (4), and chamfer the edge of the opening to avoid scratching the wire sheath; connect the trigger wire (10) and the safety wire (11) to the corresponding colored wires in the firing mechanism (13) through the foolproof connector to ensure that the wiring is correct, and then insert the free ends of the trigger wire (10) and the safety wire (11) from the front end of the wire tube (4) until the wires pass smoothly through the entire wire tube (4); after tidying up the excess length of the trigger wire (10) and the safety wire (11), put them into the cavity of the support frame (9) to ensure that the excess wires are not exposed or loose and to avoid contact with moving parts.

[0040] Finally, complete the assembly of other components of the firing mechanism: mount the firing mechanism body (5) onto the guide tube (4) to ensure that the firing mechanism body (5) can move freely back and forth along the guide tube (4) without any jamming; assemble the middle section tube (1), firing spring (7), screw plug (12) and other components in sequence to ensure that the entire firing mechanism is fully assembled and operates smoothly, and that the wiring structure does not affect the normal operation of the firing mechanism.

[0041] The working process of this invention is as follows:

[0042] When the firing mechanism performs actions such as cocking, switching on / off the safety, and firing, the cocking body (5) moves back and forth along the wire tube (4), and the trigger, safety, and other moving parts move synchronously. Since all wires are inserted into the wire tube (4), the wire tube (4) is effectively isolated from the moving parts, and the wires will not interfere with or rub against the cocking body (5), trigger, or other moving parts, ensuring that the wires are intact and that the electrical signals can be stably transmitted to the internal computer. When it is necessary to test, maintain, or replace the wires, simply disconnect the connectors connecting the trigger wiring (10), the safety wiring (11), and the firing body (13) to pull the wires out of the wire tube (4). There is no need to disassemble the entire firing mechanism, making the operation convenient and efficient. After maintenance, the wires are reinserted into the wire tube (4), reconnected through the connectors, and excess wires are stored in the cavity of the support frame (9), thus completing the maintenance assembly.

[0043] To further explain, in this embodiment, the conduit (4) is made of polytetrafluoroethylene, which has both insulation and wear resistance. Its inner diameter is designed to be 8mm, which can accommodate the insertion of 6 wires while avoiding wire compression. The opening diameter in the middle of the conduit (4) is 5mm, which is compatible with the wire diameter of the hanging switch (2). The support frame (9) is made of engineering plastic, and its cavity size is 20×15×10mm, which can accommodate excess wire length. The rubber ring (8) adopts a standard specification of 7.5×1.8mm to ensure sealing and buffering effect.

[0044] This invention's multi-line wiring structure, based on a small space, solves the problem of multi-line wiring within a limited space in a firing mechanism through scientific structural design. It effectively isolates the wires from moving parts, preventing wire wear, and simplifies disassembly and maintenance processes, meeting the simulation and practicality requirements of training equipment. For other types of firing mechanisms, using a similar wire conduit and support frame structure can achieve wire connectivity and electrical signal transmission, demonstrating broad application value.
