DETAILED DESCRIPTION

[0029] The technical solutions in the utility model embodiments will be clearly and completely described below with reference to the drawings in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] In the description of the utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the utility model.

[0031] Please refer to Figures 1-7 The utility model discloses a screw buckle type power line connector, including male end 1 and female end 2, one end of male end 1 is installed with male positioning piece 7, the inside of male positioning piece 7 is set with mounting groove 701, the inside of mounting groove 701 is equipped with spring 10, the outer surface of male positioning piece 7 is equipped with self-locking cap 8, the inner wall of self-locking cap 8 is fixedly installed with driving block 801, one end of spring 10 is in contact with driving block 801, the other end is in contact with mounting groove 701, and driving block 801 is located in mounting groove 701, the outer surface of female end 2 is equipped with female positioning piece 9, the inside of female positioning piece 9 is equipped with female waterproof ring 11, female positioning piece 9 is connected with self-locking cap 8,

[0032] Through female waterproof ring 11, the interference fit is formed after the insertion of female positioning piece 9 and male positioning piece 7.

[0033] When the connection operation needs to be implemented, the male positioning member 7 is aligned with the female positioning member 9 and inserted, and in the process of inserting the male positioning member 7 into the female positioning member 9, the male positioning member 7 extrudes the female waterproof ring 11, so that the female waterproof ring 11 is deformed and fills the gap between the two, thereby realizing waterproof sealing through interference fit, effectively preventing impurities such as water and dust from entering the inside of the connector, and ensuring the safety and stability of electrical connection, meeting the use requirements in the environment with extremely high waterproof requirements such as aviation and radar.

[0034] In terms of connection stability, the self-locking rotary cover 8 outside the male positioning member 7 plays a key role when the male end 1 is connected with the female end 2. In the initial state, the spring 10 is in a natural state, with one end abutting against the inner wall of the mounting groove 701 and the other end abutting against the driving block 801. In the process of inserting the male positioning member 7 into the female positioning member 9, the female positioning member 9 guides the self-locking rotary cover 8 entering its inside, so that the self-locking rotary cover 8 rotates axially relative to the male positioning member 7. The driving block 801 rotates in the mounting groove 701 along with the self-locking rotary cover 8, and the driving block 801 compresses the spring 10 in the mounting groove 701, storing elastic potential energy. With the movement of the self-locking rotary cover 8, the female positioning member 9 no longer guides and limits the self-locking rotary cover 8. The self-locking rotary cover 8 returns to the original position under the elastic force of the spring 10 and is clamped with the female positioning member 9. This clamping and the elastic force of the spring 10 form a strong locking force between the male end and the female end, which can effectively resist the separation tendency caused by external force interference such as vibration and impact, avoid the situation that the traditional connector is loose and the equipment is powered off due to vibration during frequent take-off and landing of an aviation aircraft, ensure reliable connection of the male end and the female end in various complex working conditions, and ensure continuous and stable power supply of electrical equipment, so that it is suitable for fields with extremely high connection stability requirements such as radar, microwave communication, digital communication, etc.

[0035] In addition, in specific applications, the materials used for the male end 1 and the female end 2 are TPEE95.

[0036] In one embodiment, for the male end 1 described above, the inner cavity of the male end 1 is provided with a plurality of male power pins 3 and a plurality of male signal pins 4, and the plurality of male power pins 3 and the plurality of male signal pins 4 are located inside the male positioning member 7. One of the plurality of male power pins 3 is provided with a power pin anti-electric shock glue 301.

[0037] The inside of the female end 2 is provided with a plurality of female power holes 5 and a plurality of female signal holes 6, and the plurality of female power holes 5 and the plurality of female signal holes 6 are located inside the female positioning member 9. The inside of each of the plurality of female power holes 5 is provided with a crown spring hole 501.

[0038] The plurality of male power pins 3 are respectively inserted into the plurality of female power holes 5 to ensure good electrical contact between the male power pins 3 and the female power holes 5 by the crown spring hole 501, thereby increasing the number of plugging and unplugging. The plurality of male signal pins 4 are respectively inserted into the plurality of female signal holes 6.

[0039] When the male end 1 is connected to the female end 2, the plurality of male power pins 3 and the plurality of male signal pins 4 in the male end 1 are inserted into the corresponding female power holes 5 and female signal holes 6 in the female end 2 together with the male end positioning member 7. For the power transmission part, when the male power pins 3 are inserted into the female power holes 5, the crown spring hole 501 in the female power holes 5 plays a key role. The crown spring has good elasticity and self-adaptability. During the insertion of the male power pins 3, the crown spring will be elastically deformed and tightly wrapped around the male power pins 3. By using the elastic force, a stable electrical contact interface is formed between the male power pins 3 and the female power holes 5. Compared with the traditional simple contact connection, the reliability and stability of the electrical connection are greatly improved. The connector can withstand more times of plugging and unplugging while still maintaining good power transmission performance, significantly prolonging the service life of the connector and meeting the requirements of frequent maintenance and repair of equipment in fields such as aviation and radar.

[0040] At the same time, the male signal pins 4 are inserted into the female signal holes 6 to establish a signal transmission path, ensuring normal signal interaction between electrical equipment. In the application scenarios such as microwave communication and digital communication, which have very high requirements for signal transmission accuracy and stability, data can be accurately transmitted, maintaining the efficient and stable operation of the entire electrical system.

[0041] The power pin anti-electric shock glue 301 at one end of the male power pin 3 is used to prevent electric shock during use.

[0042] In addition, in specific applications, the male power pins 3 use a crimping and assembling process to prevent virtual welding and false welding during welding; the crown spring hole 501 uses a crimping and assembling process to prevent virtual welding and false welding during welding.

[0043] In one embodiment, for the self-locking screw cap 8 described above, a plurality of triangular blocks 802 are fixedly installed on the inner wall of the self-locking screw cap 8, and a plurality of clamping grooves 902 are formed on the outer wall of the female end positioning member 9.

[0044] The plurality of triangular blocks 802 can be respectively located in the clamping grooves 902, and the clamping grooves 902 guide the triangular blocks 802 into the clamping grooves 902 for clamping.

[0045] When the male end 1 and the female end 2 are connected, the triangular block 802 on the inner wall of the self-locking rotary cover 8 is located at the entrance of the clamping groove 902 of the female end positioning member 9, and as the self-locking rotary cover 8 moves, the clamping groove 902 guides the triangular block 802 to rotate along the track of the clamping groove 902. At this time, the self-locking rotary cover 8 starts to rotate, so that the self-locking rotary cover 8 rotates axially relative to the male end positioning member 7, and the driving block 801 rotates in the mounting groove 701 along with the self-locking rotary cover 8, which compresses the spring 10 in the mounting groove 701 and stores elastic potential energy. As the self-locking rotary cover 8 moves, the triangular block 802 will completely enter the clamping groove 902, and once the triangular block 802 enters the clamping groove 902, the self-locking rotary cover 8 will return to its original state under the elastic force of the spring 10. Due to the shape and size limitation of the clamping groove 902, the triangular block 802 cannot easily reverse out, thereby achieving firm clamping of the self-locking rotary cover 8 and the female end positioning member 9. This clamping method tightly locks the male end and the female end together to form a stable connection structure, effectively preventing accidental separation of the male end and the female end due to external forces, greatly improving the overall connection stability of the connector and ensuring the reliability of electrical connection under various complex working conditions.

[0046] In one embodiment, for the above-mentioned female end positioning member 9, one end of the female end positioning member 9 is provided with a rubber gasket 903, which is installed on the female end positioning member 9 through screws on the four corners.

[0047] The rubber gasket 903 installed on one end of the female end positioning member 9 is fixed on the female end positioning member 9 by four corner screws. When the female end positioning member 9 is not in use, the rubber gasket 903 is sleeved on the female end positioning member 9, which can prevent dust, moisture and other impurities from entering the inside of the female end positioning member 9.

[0048] In the description of the present specification, the description of the terms "one embodiment", "example", "specific example" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the utility model. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.
