[0002] In addition to meeting general performance requirements, electrical connectors must have good contact, reliable operation, and easy maintenance. Their reliability directly affects the normal operation of the aircraft circuit and involves the safety of the entire host.

[0003] Existing electrical connectors utilize connection pins and connection terminals for clamping. Since the friction between the connection pins and the connection terminals is relatively large, it is laborious to plug and unplug them. This makes it inconvenient to quickly disconnect the connection of the electrical connector in an emergency. Therefore, a plug-in electrical connector is proposed to address the above problem. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, the existing electrical connector uses wiring pins and wiring terminals for clamping. Since the friction between the wiring pins and the wiring terminals is relatively large, it is more laborious to plug and unplug. This leads to the problem that it is not convenient to quickly separate the connection of the electrical connector in an emergency. The utility model proposes a plug-in electrical connector.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a straight-plug electrical connector described in the utility model comprises a plug-in shell, a plug-in slot is provided on one end surface of the plug-in shell, a compression plate is slidably installed in the plug-in slot, a spring is fixedly connected to one side surface of the compression plate, one end of the spring away from the compression plate is fixedly connected to an end surface of the plug-in slot, a plug-in rod is detachably plugged in the plug-in slot and is located outside the compression plate, a sealing plate is fixedly connected to the end surface of the plug-in rod away from the compression plate, the outer surface of the plug-in rod is not in contact with the inner surface of the plug-in slot, and a positioning rod for limiting the plug-in rod is detachably installed on the plug-in shell.

[0006] Preferably, a positioning head is fixedly connected to the center of one side surface of the compression plate at the plug-in rod, and a connecting hole corresponding to the positioning head is opened in the center of one side surface of the compression plate at the plug-in rod.

[0007] Preferably, two opposite side surfaces in the plug-in slot are provided with slide grooves, two groups of slide grooves are slidably installed with sliders, and one side surface of the two groups of sliders opposite to each other is fixedly connected to the two side surfaces of the compression plate respectively.

[0008] Preferably, a limiting groove is provided on the lower inner surface of the plug-in slot, and a limiting block corresponding to the limiting groove is fixedly connected to the lower surface of the plug-in rod.

[0009] Preferably, a plug hole penetrating into the plug slot is provided on the upper outer surface of the plug-in housing at the plug-in rod, the positioning rod is detachably plugged into the plug hole, and a pull plate is fixed to the upper end of the positioning rod.

[0010] Preferably, a nut is fixedly mounted on the upper surface of the plug-in housing, the nut is concentric with the plug-in hole, a positioning hole corresponding to the positioning rod is opened on the upper surface of the plug-in rod, and a thread corresponding to the nut is arranged on the positioning rod below the pull plate.

[0011] The utility model is beneficial in that:

[0012] 1. The utility model inserts the plug rod into the plug slot when the electrical connector is connected, so that one end of the plug rod fits against the surface of one side of the compression plate, and pushes it to slide inward while compressing the spring, so that the plug rod is completely located in the plug slot, and at the same time, the surface of one side of the sealing plate will also fit against the end of the plug housing to close the plug slot, and then the plug rod is locked in the plug slot under the action of the positioning rod. When disassembly is required, the plug rod is removed, and the plug rod is popped out of the plug slot under the action of the spring rebound. Since the outer surface of the plug rod is not in contact with the inner surface of the plug slot, the friction can be reduced and separation is facilitated, thereby achieving the purpose of separation, and solving the problem that the friction between the wiring pin and the wiring terminal is large when connected, so it is more laborious when plugging and unplugging, which makes it inconvenient to quickly separate the connection of the electrical connector in an emergency.

[0013] 2. The utility model adopts the design of two sets of sliding grooves to make the two sets of sliding blocks slidably installed in the plug-in grooves. Due to the fixed connection between the sliding block and the compression plate, the compression plate is slidably installed in the plug-in grooves through the two sets of sliding blocks. When the plug-in rod is installed in the plug-in groove, the limit block is simultaneously located in the limit groove and slidably inserted inwardly, so that the plug-in rod will not rotate in the plug-in groove, which has a positioning effect on the plug-in rod, which is convenient for the positioning rod to position it. The positioning rod is installed on the plug-in housing through the plug-in hole. Since the positioning rod is located in the plug-in groove, it has a positioning effect on the plug-in rod. Through the design of the pull plate, it is convenient to disassemble the positioning rod, and the plug-in rod is fixed by inserting the bottom end of the positioning rod into the positioning rod. Then, the positioning rod is rotated to lock the positioning rod through the nut under the action of the thread. When separation is required, the positioning rod is rotated to release the nut, and the positioning rod is pulled out to release the lock of the plug-in rod so that it pops out automatically, thereby achieving the purpose of quick separation.

[0021] When working, when the electrical connector is connected, the plug rod 18 is plugged into the plug slot 2, so that one end of the plug rod 18 is in contact with the surface of one side of the compression plate 4, and it is pushed to slide inward while compressing the spring 7, so that the plug rod 18 is completely located in the plug slot 2, and at the same time, the surface of one side of the sealing plate 3 will also be in contact with the end of the plug shell 1 to close the plug slot 2. Subsequently, the plug rod 18 is locked in the plug slot 2 under the action of the positioning rod 14. When disassembly is required, the plug rod 18 is removed, and the plug rod 18 is popped out of the plug slot 2 under the action of the rebound of the spring 7. Since the outer surface of the plug rod 18 is not in contact with the inner surface of the plug slot 2, the friction can be reduced and separation is facilitated, thereby achieving the purpose of separation, solving the problem that the friction between the wiring pin and the wiring terminal is large when connected, so it is more laborious when plugging and unplugging, which makes it inconvenient to quickly separate the connection of the electrical connector in an emergency.

[0022] Furthermore, a positioning head 11 is fixedly connected to the plug rod 18 at the center of one side surface of the compression plate 4 , and a connecting hole 10 corresponding to the positioning head 11 is opened at the center of one side surface of the compression plate 4 at the plug rod 18 .

[0023] During operation, when the plug-in rod 18 is attached to the surface of the compression plate 4 , the positioning head 11 will also be located in the connecting hole 10 , and the plug-in rod 18 has a limiting function.

The opposite side surfaces of the two groups of sliders 6 are fixedly connected to the two side surfaces of the compression plate 4 respectively.

[0025] During operation, the two sets of slide grooves 5 are designed to enable the two sets of sliders 6 to be slidably installed in the plug-in grooves 2. Since the sliders 6 are fixedly connected to the compression plate 4, the compression plate 4 is slidably installed in the plug-in grooves 2 through the two sets of sliders 6.

[0026] Furthermore, a limiting groove 8 is provided on the lower inner surface of the plug-in slot 2 , and a limiting block 9 corresponding to the limiting groove 8 is fixedly connected to the lower surface of the plug-in rod 18 .

[0027] During operation, when installing the plug rod 18 into the plug slot 2, the limit block 9 is simultaneously located in the limit slot 8 and slid inwardly, so that the plug rod 18 will not rotate in the plug slot 2, which has a positioning effect on the plug rod 18, making it easier for the positioning rod 14 to position it.

[0030] Furthermore, a nut 12 is fixedly mounted on the upper surface of the plug-in housing 1, the nut 12 is concentric with the plug-in hole 17, a positioning hole 13 corresponding to the positioning rod 14 is opened on the upper surface of the plug-in rod 18, and a thread 15 corresponding to the nut 12 is provided on the positioning rod 14 below the pull plate 16.

[0031] During operation, the plug-in rod 18 is fixed by inserting the bottom end of the positioning rod 14 into the positioning rod 14, and then the positioning rod 14 is rotated to lock the positioning rod 14 through the nut 12 under the action of the thread 15. When separation is required, the positioning rod 14 is rotated to release the nut 12, and the positioning rod 14 is pulled out to unlock the plug-in rod 18 and make it pop out automatically, thereby achieving the purpose of quick separation.

[0032] Working principle: through the design of two sets of slide grooves 5, two sets of sliders 6 are slidably installed in the plug-in slot 2. Due to the fixed connection between the slider 6 and the compression plate 4, the compression plate 4 is slidably installed in the plug-in slot 2 through the two sets of sliders 6. When the plug-in rod 18 is installed in the plug-in slot 2, the limit block 9 is simultaneously located in the limit groove 8 and slid inwardly, so that the plug-in rod 18 will not rotate in the plug-in slot 2, which has a positioning effect on the plug-in rod 18, which is convenient for the positioning rod 14 to position it, and the positioning rod 14 is installed on the plug housing 1 through the plug hole 17.
