Description

Technical Field

[0001] This application relates to the field of connectors, and more particularly to a connector that is easy to snap on. Background Technology

[0002] In the use of connectors, after the male and female plugs are inserted, the stability of the connection is usually achieved through the contact or interference fit of their own materials. However, this fixed connection method can cause the male and female plugs to gradually move outward and eventually separate when encountering equipment with frequent vibration. Users need to tighten the male and female plugs from time to time to secure them, which results in poor stability. Utility Model Content

[0003] To improve the poor stability of male and female plug connections, this application provides a connector that is easy to snap on.

[0004] This application provides a connector that facilitates snap-fitting, employing the following technical solution:

[0005] A connector for easy snap-fit ​​includes a male plug and a female plug. The female plug has a insertion groove for the male plug to be inserted and mated. A locking block is provided on the inner wall of the insertion groove. The male plug has an elastic piece with a locking groove for the locking block to enter and engage.

[0006] By adopting the above technical solution, when the male plug is inserted into the socket, the elasticity of the elastic sheet first makes way for the locking block, and then the locking block is inserted into the socket, making it difficult for the male plug to be pulled out, which greatly improves the stability of the male plug and female plug connection.

[0007] Optionally, a guide slope is formed on the elastic sheet, which is used to abut against the locking block to drive the elastic sheet to deform and make way.

[0008] By adopting the above technical solution, the elastic sheet is guided by the inclined plane to deform after being resisted by the locking block, making the deformation of the elastic sheet smoother and the sliding of the locking block smoother.

[0009] Optionally, the elastic sheet has a relief groove for the card block to slide into, and the guide slope is formed on the inner wall of the relief groove.

[0010] By adopting the above technical solution, the clearance groove is used to make room for the card block, reducing the friction between the card block and the elastic plate over a long distance, and also reducing the reaction force experienced by the user when inserting, making the process of inserting the male plug into the female plug smoother.

[0011] Optionally, the elastic sheet is provided with a stop, which is used to abut against the outer wall of the female insert after the card block is inserted into the card slot.

[0012] By adopting the above technical solution, the stop block facilitates the removal of the male connector by pressing the elastic piece, thereby increasing the force application area for the user.

[0013] Optionally, an inclined block is provided between the elastic sheet and the stop block, the inclined block being used to abut against the edge of the insertion slot opening surface to lift and deform the elastic sheet.

[0014] By adopting the above technical solution, when the slot and the block are aligned, the elastic sheet is blocked by the inclined block and cannot fully release the deformation force, so that the elastic force is continuously applied and the inner wall of the slot is pressed against the block, which greatly improves the stability and reduces the probability of external force affecting the male connector.

[0015] Optionally, an extension plate is rotatably provided on the stop block, and the extension plate has a pull groove for the user to pull.

[0016] By adopting the above technical solution, the extension plate's groove makes it easier for users to pull the male connector out of the socket.

[0017] Optionally, the extension plate is provided with an abutment block, which is used to abut against the elastic sheet after the extension plate is rotated out, so as to limit the rotation angle of the extension plate.

[0018] By adopting the above technical solution, the abutting block abuts against the elastic sheet, making it difficult for the extension plate to continue rotating. At this time, the user can press the extension plate to cause the elastic sheet to deform, causing the locking block to exit from the slot, thus extending the lever arm and making it easier for the user to press the elastic sheet.

[0019] Optionally, the length of the extension plate is greater than the extension length of the stop.

[0020] By adopting the above technical solution, when the extension plate abuts against the stop block, it is convenient for the user to rotate the extension plate.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. It greatly improves the stability of male and female plug connections.

[0023] 2. Utilize elasticity to improve the stability of the card block against the inner wall of the card slot.

[0024] 3. Facilitates control of the elastic sheet. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] Embodiment 1 of this application discloses a connector that facilitates snap-fitting. (See also...) Figure 1 and Figure 2 The connector for easy snap-fit ​​includes a male plug 1 and a female plug 2. The female plug 2 has a plug groove 21 for the male plug 1 to be inserted and mated. The inner wall of the plug groove 21 fits against the outer wall of the male plug 1 when inserted. A locking block 22 is integrally formed on the inner wall of the plug groove 21 and is located on the side wall of the opening surface of the plug groove 21. An elastic piece 11 is integrally formed on the outer wall of the male plug 1. The elastic piece 11 is made of a material with restoring elasticity, such as insulating plastic or rubber. One end of the elastic piece 11 is fixedly connected to the outer wall of the male plug 1, and the position of the elastic piece 11 is the position where the male plug 1 first enters the plug groove 21. The extension direction of the elastic piece 11 is parallel to the direction in which the male plug 1 is inserted into the plug groove 21. A locking groove 12 is formed on the side wall of the elastic piece 11 facing away from the male plug 1 for the locking block 22 to enter and engage.

[0034] Reference Figure 1 and Figure 2The elastic sheet 11 has a clearance groove 14 on its side wall facing away from the male insert 1 for the locking block 22 to slide into. The clearance groove 14 and the locking slot 12 are distributed sequentially along the extension direction of the elastic sheet 11. A guide slope 13 is formed on the inner wall of the clearance groove 14 near the locking slot 12. The guide slope 13 is inclined in a direction that is closer to the opening surface of the clearance groove 14 as it gets closer to the locking slot 12. The guide slope 13 is used to abut against the locking block 22 to drive the elastic sheet 11 to deform and make clearance so that the locking block 22 can enter the locking slot 12.

[0035] Reference Figure 1 and Figure 2 A stop block 3 is fixedly connected to the end of the elastic piece 11 away from the connection with the male plug 1. The stop block 3 extends in a direction away from the male plug 1, and the extension direction of the stop block 3 is perpendicular to the extension direction of the elastic piece 11. The stop block 3 is used to abut against the outer wall of the female plug 2 around the opening surface of the insertion groove 21 after the card block 22 is inserted into the card slot 12.

[0036] Reference Figure 2 and Figure 3 and Figure 4 An inclined block 31 is integrally formed between the elastic sheet 11 and the stop block 3. The inclined block 31 is triangular prism-shaped. The three sides of the inclined block 31 forming a triangle are fixed on the elastic sheet 11, fixed on the stop block 3, and an empty side. The empty side is inclined. The inclination direction of the empty side is the same as the inclination direction of the guide inclined surface 13. The inclined side of the inclined block 31 is used to abut against the edge of the opening surface of the insertion groove 21 to lift and deform the elastic sheet 11.

[0037] The implementation principle of a fastening connector according to Embodiment 1 of this application is as follows: When it is necessary to connect a male plug 1 and a female plug 2, the male plug 1 is aligned with the insertion slot 21 and inserted. First, the locking block 22 slides into the clearance slot 14. As the male plug 1 continues to go deeper, the locking block 22 abuts against the guide inclined surface 13, thereby pushing the elastic piece 11 to deform and make clearance. As the male plug 1 continues to go deeper, the locking block 22 aligns with the slot 12, and the elastic piece 11 releases its deformation, so that the inner wall of the slot 12 is fastened to the locking block 22. At this time, the inclined surface of the inclined block 31 abuts against the edge of the opening surface of the insertion slot 21, so that the elastic piece 11 cannot completely release its deformation, and the elastic force of the elastic piece 11 acts along the inclined block 31 on the edge of the opening surface of the female plug 2, so that the elastic piece 11 forms a reaction force perpendicular to the inclined surface of the inclined block 31 on the male plug 1, so that the inner wall of the slot 12 is pressed against the locking block 22.

[0038] Example 2:

[0039] Unlike Example 1, referring to Figure 5 and Figure 6The connector for easy snap-fit ​​also includes an extension plate 4 rotatably connected to the stop block 3, with the rotation axis of the extension plate 4 positioned near the male connector 1 on the stop block 3. A pull groove 41 for the user to pull the extension plate 4 is provided near the rotation axis. An abutment block 42 is fixedly connected to the rotation axis of the extension plate 4. The abutment block 42 abuts against the elastic sheet 11 after the extension plate 4 is rotated out, thereby limiting the rotation angle of the extension plate 4. The extension plate 4 extends away from the rotation axis beyond the stop block 3, such that the length of the extension plate 4 is greater than the extension length of the stop block 3.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
