Description

Technical Field

[0001] This utility model belongs to the field of aviation hydraulic servo plug technology, specifically an aviation hydraulic servo plug terminal structure. Background Technology

[0002] Aviation connectors, also known as aviation plugs, are electromechanical components widely used in various electrical circuits. They serve to connect or disconnect circuits. Their terminal block (or contact) structure is the core part of the connector to complete the electrical connection function. Aviation connector terminals generally consist of male and female contacts forming a contact pair, and the electrical connection is completed by the mating of the male and female contacts.

[0003] Aviation hydraulic servo connectors are connectors used in aviation hydraulic systems, typically for connecting components such as servo valves and proportional valves. In the aerospace field, the application of hydraulic servo connectors is crucial because they ensure the reliability and safety of hydraulic systems.

[0004] Traditional aviation hydraulic servo connectors have exposed terminals that cannot be disassembled and stored. During post-production transportation or handling, a plastic protective sleeve is usually placed over the exposed terminals to protect them from wear. However, this protective sleeve only prevents wear on the terminals. In the event of bumps or impacts, the connector rods on the terminals can easily deform, compromising the reliability and safety of the aviation hydraulic servo connector and rendering it unusable. Utility Model Content

[0005] To address the issue that the exposed terminals of traditional aviation hydraulic servo plugs cannot be disassembled and stored, and that the plug rods on the terminals are prone to deformation under conditions such as bumps and impacts, leading to compromised reliability and safety of the aviation hydraulic servo plug and ultimately rendering it unusable, this invention provides a new aviation hydraulic servo plug terminal structure.

[0006] This utility model is achieved through the following technical solution:

[0007] A terminal block structure for an aviation hydraulic servo connector includes a connector body and a connector base. The connector body is connected to a base, and the base has a plurality of conductive posts. One side of the connector base has a conductive hole that can be positioned and inserted with the conductive posts, and the other side has a plug rod corresponding to the conductive posts and a mounting groove that can accommodate the conductive posts. When the conductive posts are positioned and inserted with the conductive holes, the plug rods are electrically connected to the conductive posts. The base has a socket that can be inserted and installed with the plug rods.

[0008] A further improvement of this utility model is that the base is provided with several slots, and the side of the connecting seat near the conductive hole is provided with several claws that are positioned and engaged with the slots.

[0009] A further improvement of this utility model is that the edge of the mounting groove is chamfered.

[0010] A further improvement of this invention is that the ends of the conductive posts are chamfered.

[0011] A further improvement of this invention is that the edges of the conductive holes are chamfered.

[0012] A further improvement of this utility model is that a locking block is provided on the inner side of the end of the claw away from the connecting seat, and the inner edge of the locking block away from the connecting seat has a chamfer.

[0013] A further improvement of this utility model is that three conductive posts are evenly arranged in a ring; and the insertion holes are evenly spaced from the conductive posts.

[0014] A further improvement of this utility model is that the end of the plug rod near the connector is provided with a slot that can be inserted and connected to the conductive post.

[0015] A further improvement of this utility model is that a conductive sleeve capable of being inserted into the conductive hole is provided, and the insertion rod is positioned and connected to the upper part of the conductive sleeve.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] During normal use, the conductive post is positioned and inserted into the conductive hole on the connector base to achieve electrical connection between the connector rod and the conductive post, thus enabling the normal use of this aviation hydraulic servo connector. For storage and transportation, the connector base is removed and flipped over, allowing the connector rod on the connector base to insert into the socket on the base, and the conductive post on the base to engage with the mounting slot on the connector base. This effectively protects the conductive post and connector rod, preventing deformation caused by impacts to the terminals during transportation, handling, and storage, ensuring the reliability and safety of the aviation hydraulic servo connector. The overall structure is simple, easy to use, and highly practical. Attached Figure Description

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figure 1-4 As shown, this utility model discloses a terminal block structure for an aviation hydraulic servo plug, including a plug body 1 and a connector 3; one end of the plug body 1 is connected to a base 2, and the base 2 is provided with a plurality of conductive posts 202; one side of the connector 3 is provided with a conductive hole 304 that can be positioned and inserted into the conductive post 202, and the other side is provided with a plug rod 302 corresponding to the conductive post 202 and a mounting groove 303 that can accommodate the conductive post 202; when the conductive post 202 is positioned and inserted into the conductive hole 304, the plug rod 302 is electrically connected to the conductive post 202; the base 2 is provided with a socket 203 that can be inserted and installed into the plug rod 302.

[0026] When the aviation hydraulic servo connector is in normal use, the conductive post 202 is positioned and inserted into the conductive hole 304 on the connector 3 to achieve electrical connection between the connector rod 302 and the conductive post 202. Figure 1 As shown, this enables the normal use of the aviation hydraulic servo plug; during storage and transportation, the connector 3 is removed and flipped over so that the plug rod 302 on the connector 3 is inserted into the socket 203 on the base 2 (with a certain relative static friction to prevent the connector 3 from falling off automatically), and the conductive post 202 on the base 2 is inserted into the mounting groove 303 on the connector 3 (with a certain relative static friction to prevent the connector 3 from falling off automatically). Figure 4As shown, this design effectively protects the conductive post 202 and the plug rod 302, preventing deformation caused by impacts to the wiring terminals during transportation, handling, and storage, thus ensuring the reliability and safety of the aviation hydraulic servo plug. The overall structure is simple, easy to use, and highly practical.

[0027] The connector 3 is made of insulating plastic and is integrally injection molded with the plug rod 302.

[0028] The base 2 has several evenly spaced slots 201, and the connecting seat 3 has several claws 301 on the side near the conductive hole 304, which are positioned and engaged with the slots 201. There are two slots 201 and two claws 301, arranged opposite each other. During normal use (when the plug rod 302 is electrically connected to the conductive post 202), the two claws 301 engage with the two slots 201, ensuring the reliability and stability of the connection between the connecting seat 3 and the base 2.

[0029] Furthermore, such as Figure 2 , 3 As shown, the claw 301 has a certain elasticity. The inner side of the end of the claw 301 away from the connecting seat 3 is provided with a locking block. The inner edge of the locking block away from the connecting seat 3 is chamfered, which plays a guiding role and can realize the convenient, smooth and reliable engagement of the claw 301 and the slot 201.

[0030] Furthermore, three conductive posts 202 are evenly spaced in a ring; and the insertion holes 203 are evenly spaced from the conductive posts 202, with two claws 301 corresponding to one insertion rod 302 and one mounting slot 303 respectively. This arrangement is reasonable; when the connector 3 is flipped for protection, accurate insertion can be achieved by simply flipping it 180 degrees (claws 301 correspond to slots 201). Figure 4 As shown.

[0031] To ensure easy insertion, the edges of the mounting slot 303 are chamfered. The ends of the conductive post 202 are chamfered. The edges of the conductive hole 304 are chamfered. The chamfering serves as a guide during insertion.

[0032] In one embodiment, the end of the plug rod 302 near the connector 3 has a slot for insertion and connection with the conductive post 202. The conductive post 202 is directly inserted into the slot at the end of the plug rod 302 to achieve electrical connection between the two, and the conductive hole 304 serves as a guide when the conductive post 202 is inserted.

[0033] In another embodiment, a conductive sleeve capable of being inserted into the conductive post 202 is embedded in the conductive hole 304, and the insertion rod 302 is positioned and connected to the upper part of the conductive sleeve. The conductive sleeve serves as a transitional conductive connector, thus achieving ease of use.

[0034] In normal use, the conductive post 202 is positioned and inserted into the conductive hole 304 on the connector 3 to achieve electrical connection between the connector rod 302 and the conductive post 202. Figure 1 As shown, this allows for the normal use of the aviation hydraulic servo connector. During storage and transportation, the connector 3 is removed and flipped over, allowing the plug rod 302 on the connector 3 to insert into the socket 203 on the base 2 (with a certain relative static friction to prevent the connector 3 from falling off automatically). The conductive post 202 on the base 2 inserts into the mounting groove 303 on the connector 3 (with a certain relative static friction to prevent the connector 3 from falling off automatically). This effectively protects the conductive post 202 and the plug rod 302, preventing deformation caused by impact damage to the terminals during transportation, handling, and storage, ensuring the reliability and safety of the aviation hydraulic servo connector. The overall structure is simple, easy to use, and highly practical.
