[0002] With the development of connector field, multi-core connector is increasingly widely used in industry, communication and power and the like field. However, in actual use, the existing connector female seat still has certain deficiency in anti-loose performance, structural stability and operation convenience. Especially in the working condition of vibration, impact or frequent plugging, the traditional female seat is prone to looseness or even falling off, which affects the normal operation of equipment.

[0003] Through the retrieval, a kind of anti-loose power connection device and its plug and socket of anti-loose are disclosed, and the publication date is April 10, 2018. The design is set up by preventing the plug and socket from falling off, and the vertical surface is realized by gap cooperation to limit the height of the plug lifting, to achieve the effect of anti-loose. Although this structure can effectively prevent the plug from falling off, its anti-loose mechanism mainly depends on the external mechanical limiting structure, and the fixing effect between the internal wire hole and the pin has not been optimized. In addition, the design does not consider the integrated design of female seat rubber core and shell, which may cause relative displacement between rubber core and shell after long-term use, and then affect the stability of overall connection.

[0004] The above problems show that the traditional connector female seat on the market still needs to be improved in anti-loose performance, structural stability and operation convenience. Especially for multi-core connector, how to simplify the structure design and improve the overall stability while ensuring the anti-loose effect is still a technical problem to be solved. Therefore, the utility model provides a kind of anti-loose connection female seat, which significantly improves the anti-loose performance and structural stability by the integrated design of rubber core and shell and the optimized configuration of wire stabilizing terminal, to meet the needs of modern industry for efficient and reliable connector.

The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used in this description, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] The utility model will be explained in detail below in combination with each embodiment shown in the accompanying drawings:

[0024] As Figures 1-4As shown, in the embodiment, the utility model provides a kind of anti-loose connection female seat, including rubber core 1 and shell 2.Rubber core 1 is integrally formed with shell 2, and rubber core 1 is internally provided with multiple wire holes 3, and wire hole 3 is used to be inserted with the pin of male connector, and wire hole 3 is internally provided with wire stabilizing terminal 4.Shell 2 is peripherally arranged in rubber core 1, and the inner wall of shell 2 is provided with multiple anti-skid lines 7, which can effectively prevent the male connector from sliding out of the female connector seat.Sealing rubber ring 8 is fixedly arranged at the top opening of shell 2, which can improve the sealing performance of the female connector seat after being connected with the male connector.

[0025] Rubber core 1 and shell 2 are formed by one-shot injection molding process, ensuring that they are tightly combined without seams.Wire holes 3 are arranged in a matrix inside rubber core 1, and each wire hole 3 is internally provided with wire stabilizing terminal 4. Figure 3 As shown, it includes two half-cylinder clamping leaves 5 connected by a metal gasket 6.The inner side of clamping leaf 5 is provided with a friction strip to further increase the friction between the pin.The metal gasket 6 has a certain elasticity and can provide restoring force when the clamping leaf 5 is opened, ensuring that the clamping leaf 5 can firmly hold the pin after insertion.

[0026] The specific structure of wire stabilizing terminal 4 is: clamping leaf 5 is half-cylindrical, and both ends are connected by metal gasket 6.The thickness of metal gasket 6 is about 0.1mm, and the surface is specially treated, with good elasticity and wear resistance.The inner side of clamping leaf 5 is provided with a friction strip, which is a plurality of protrusions distributed along the axis of clamping leaf 5, with a height of about 0.2mm and a spacing of about 0.5mm.This design allows the pin to come into close contact with the friction strip when inserted, further improving the clamping force.

[0027] The structure of sealing rubber ring 8 is designed as follows: the outer side of sealing rubber ring 8 is provided with several protruding sealing teeth 9, which are arranged in a ring shape, which can increase the contact area between sealing ring 8 and male connector when the female connector is connected with the male connector, and improve the sealing performance.The inner side of sealing rubber ring 8 is provided with several small air holes 10, which can discharge the air inside the sealing rubber ring 8 when it is pressed, ensuring that the contact surface of sealing rubber ring 8 and male connector is tightly fitted.The diameter of each air hole 10 is about 0.1mm, and the depth is about 0.5mm.The distribution density of air hole 10 is 20 per square centimeter, ensuring sufficient air discharge capacity.

[0028] The anti-skid lines 7 on the inner wall of the shell 2 are designed as follows: the anti-skid lines 7 are composed of a plurality of anti-skid teeth, the shape of the anti-skid teeth is rectangular teeth, the height is about 0.5 mm, the width is about 1 mm, and the interval is about 1.5 mm. The surface of each rectangular tooth is also provided with a small pit 13, the diameter of the small pit 13 is about 0.1 mm, and the depth is about 0.1 mm. Such design significantly increases the friction between the male connector and the female connector, prevents the male connector from sliding out under vibration or impact working conditions, and improves the reliability of the overall connection.

[0029] In the process of inserting the pin into the wire hole 3, the pin first contacts the clamping leaf 5 of the wire stabilizing terminal 4, and the clamping leaf 5 is opened outward under the pushing of the pin. When the pin is completely inserted, the clamping leaf 5 will quickly close and hold the pin due to the elastic restoring force of the metal gasket 6. In this process, the friction strip on the inner side of the clamping leaf 5 will be in close contact with the surface of the pin, increasing the clamping force. At the same time, the rubber core 1 around the wire hole 3 also has a certain elasticity and can cooperate with the closing of the clamping leaf 5 to a certain extent, further improving the fixing effect of the pin.

[0030] The specific working principle is as follows:

[0031] The pin insertion process: when the pin of the male connector is inserted into the wire hole 3 of the female connector, the pin first contacts the clamping leaf 5 of the wire stabilizing terminal 4. The advancing force of the pin causes the clamping leaf 5 to open outward, and the metal gasket 6 is compressed. After the pin is completely inserted, the elastic restoring force of the metal gasket 6 causes the clamping leaf 5 to quickly close and hold the pin. The friction strip on the inner side of the clamping leaf 5 is in close contact with the surface of the pin, increasing the clamping force and preventing the pin from loosening under vibration or impact working conditions.

[0032] The connection process of the male connector and the female connector:

[0033] The front end of the male connector is inserted into the shell 2 of the female connector.

[0034] The anti-skid teeth on the inner wall of the shell 2 are in close contact with the outer wall of the male connector, increasing the friction between the two, preventing the male connector from sliding out. The sealing teeth 9 on the sealing rubber ring 8 are in contact with the outer wall of the male connector, increasing the contact area between the sealing rubber ring 8 and the male connector, and improving the sealing performance. The small air holes 10 on the inner side of the sealing rubber ring 8 discharge the internal air when pressed, ensuring that the contact surface of the sealing rubber ring 8 and the male connector is tightly fitted, avoiding air entering to reduce the sealing effect.

[0035] Specific application scenarios:

[0036] In the automobile electronic system, the anti-loose connection socket is used to connect the cables of various sensors and control units. For example, the sensor signal line connected to the automobile engine control unit. Because the automobile will encounter various vibrations and impacts during driving, the traditional connection socket is prone to looseness, which can cause unstable signal transmission. The use of the anti-loose connection socket of the utility model can effectively prevent the pin from loosening under vibration or impact conditions, ensuring the stability and reliability of signal transmission. At the same time, the design of the anti-skid teeth on the inner wall of the sealing rubber ring 8 and the shell 2 improves the dustproof and waterproof performance, and is suitable for various harsh environmental conditions.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application. For those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
