Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to an aviation plug junction box. Background Art

[0002] Aviation plug junction box is a device used for electrical connection and protection. It is commonly used in aviation, aerospace and other fields that require high reliability and durability. It is used to connect different cables and provide mechanical and electrical protection.

[0003] At present, during the use of existing aviation plug junction boxes, the plug and the slot in the aviation plug junction box need to be tightly connected to ensure the stability of the electrical connection. This makes it relatively difficult to plug and unplug the aviation plug, and the box should not be shaken left and right excessively during plugging and unplugging, otherwise it is easy to cause the pins on the aviation plug or the slot to bend or break, resulting in the inability to connect some internal circuits. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that it is difficult to plug and unplug aviation plugs or slots in the prior art, and to propose an aviation plug junction box.

[0006] An aviation plug junction box includes a mounting base box, wherein the top of the mounting base box is connected to a top junction box, and fixing bolts are threadedly connected to the top of the mounting base box near the left and right sides. The outer surfaces of the fixing bolts are also threadedly connected to the top junction box near the top of the mounting base box. A connecting rod is connected to the top of the top junction box near the front by a bearing connection, and an adjusting wheel is fixedly connected to the top of the connecting rod. A bearing ring is sleeved on the front of the top junction box near the middle, and a limiting ring is sleeved on the inner side of the bearing ring.

[0007] Preferably, the bottom of the connecting rod is fixedly connected to a first bevel gear, the bottom of the first bevel gear is meshed with a second bevel gear near the front, the front of the second bevel gear is fixedly connected to a limiting ring, and the outer surface of the limiting ring is provided with a fixing thread near the front of the bearing ring.

[0008] Preferably, a limit rod is movably sleeved on the front of the top junction box near the left side, and a placement block is fixedly connected to the front of the limit rod. A placement groove is opened and closed on the inner side of the placement block for placing the alignment protrusion on the outer surface of the aviation plug, and the placement groove on the placement block is wider than the alignment protrusion on the general aviation plug, and is used to align the pins on the aviation plug with the pin grooves in the slot, so as to avoid the situation where the aviation plug and the aviation slot are not aligned when the placement block moves, resulting in the pins being squeezed, and a sealing rubber ring is fixedly connected to the front of the limiting ring.

[0009] Preferably, the placement block is fixedly connected to a connecting block on one side close to the middle of the limiting ring, and the back of the limiting rod is fixedly connected to a limiting block. When the connecting ring is close to the front edge of the limiting ring, the limiting block fixed on the back of the limiting rod fits against the inner wall of the top junction box.

[0010] Preferably, a connecting ring is fixedly connected to the back of the connecting block, and a threaded groove is provided on the inner side of the connecting ring.

[0011] Preferably, the fixing thread and the thread groove can be threadedly connected, and a blocking block is fixedly connected to the outer surface of the connecting ring near the back. After the aviation plug is fully inserted, the blocking block fits against the front of the top junction box.

[0012] Compared with the prior art, the present invention provides an aviation plug junction box with the following beneficial effects:

[0013] 1. The aviation plug junction box is provided with a connecting ring and a first bevel gear. The first bevel gear can be driven by the second bevel gear by rotating the adjusting wheel. The limiting rod is limited so that the limiting ring drives the position of the placement block to move. After alignment, the aviation plug is pushed into the interior of the top junction box and tightly connected with the slot, which is beneficial to improving the stability of the connection and facilitating the insertion and removal of the aviation plug and the slot, thereby improving the convenience of use and reducing the risk of electrical short circuit or poor contact.

[0014] 2. The aviation plug junction box is provided with a blocking block and a limiting rod. Through the restriction of the blocking block and the limiting rod, the stability of the equipment is improved, the excessive squeezing of the aviation plug and the slot is avoided, and the dislocation of the connecting ring is avoided, thereby improving the safety of the equipment. At the same time, the provision of a sealing rubber ring improves the sealing effect between the aviation plug and the slot, prevents moisture and dust from entering the connection area, and improves environmental resistance.
