Description

Technical Field

[0001] This utility model relates to a connector, and more specifically, to a quick connector with a snap-fit ​​structure. Background Technology

[0002] A connector generally refers to an electrical connector. It is a device that connects two active devices to transmit current or signals. The male and female terminals, when in contact, can transmit information or current; this is also called a connector.

[0003] Existing connectors only connect through plug-in and use clips for locking. However, most existing clip structures rely on the elasticity of the material itself for relative fixation. After plugging, they may accidentally fall off due to vibration or external force, resulting in unstable connection. Furthermore, the limiting effect is not ideal, the contact area is small, and they are prone to wear, affecting service life.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quick connector with a snap-fit ​​structure, which makes the snap-fit ​​more stable.

[0006] The technical solution of this utility model is: A quick connector with a snap-fit ​​structure includes a female and a male connector that interlock. The female connector extends from a through hole in an outer casing. The female connector has a plug-in portion at its end facing the male connector, and the male connector has a corresponding insertion interface. The male connector includes a connector head and a body threaded to one end of the connector head. The insertion interface is located at the end of the connector head facing the female connector. An elastic snap is fixedly connected to the female connector near the male connector on the outside of the plug-in portion. An insertion channel is provided on the outer peripheral wall of the connector head for inserting the elastic snap and parallel to the axial direction of the male connector. The elastic snap has elastic deformation potential energy radially away from the outer peripheral wall of the female connector. A limiting member is provided at the insertion channel to prevent the elastic snap from disengaging from the insertion channel.

[0007] The present invention is further configured such that a through groove is provided in the middle of the limiting member and communicates with the insertion channel, and a button is movably connected to the innermost part of the insertion channel, with the bottom of the button abutting against the surface of the elastic buckle.

[0008] The present invention is further provided that the top surface of the end of the elastic buckle is provided with a limiting part extending radially outward along the female head, and the cross section of the limiting part is U-shaped, thereby forming a limiting groove.

[0009] The present invention is further configured such that a limiting part is provided on the top wall of the through groove. When the elastic buckle passes through the through groove, the elastic buckle causes the limiting part to extend into the limiting groove through its own elasticity, and the end of the limiting part fits against the inner wall of the limiting groove.

[0010] The present invention is further configured such that the cross-section of the through groove is U-shaped, so that a gap is formed between the two sides of the limiting part and the inner sidewall of the through groove.

[0011] The present invention is further configured such that the connector has an integrally formed protrusion with external threads on the outer peripheral wall at the middle of one end facing the body, and the body is fitted onto the outer peripheral wall of the protrusion and threadedly connected.

[0012] The present invention is further configured such that a support ring is fitted on the protrusion, located between the body and the connector, and the button is integrally formed on the outer peripheral wall of the support ring.

[0013] The present invention is further configured such that both the button and the support ring are made of plastic material.

[0014] The beneficial technical effects of this utility model are: By setting up a combination of elastic buckle and limiting component, it is easier and more convenient for the limiting part to extend into the limiting groove. The limiting part not only contacts the limiting part but also contacts the inner wall of the limiting component, thereby ensuring the contact area and making the relative fixation between the limiting part and the limiting component more stable, thus ensuring the insertion effect of the male and female connectors.

[0015] Furthermore, the combination of buttons and elastic components makes it easier to pull the elastic clip out of the insertion channel, thus detaching the male and female connectors and making operation more convenient. Attached Figure Description

Detailed Implementation

[0018] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] A quick connector with a snap-fit ​​structure, such as Figures 1-6 As shown, the device includes a female connector 1 and a male connector that are interlocked. Both the female connector 1 and the male connector are made of plastic. The female connector 1 extends from a through hole in the outer casing of the external part, and an external thread is provided on the outer peripheral wall of the female connector 1. The female connector 1 is fixedly connected to the external part by a nut. The end of the female connector 1 facing the male connector is provided with a plug-in part 11, and the male connector is provided with a corresponding plug-in interface 22. The male connector includes a connector 2 and a body 3 that is threaded to one end of the connector 2. The plug-in interface 22 is provided at the end of the connector 2 facing the female connector 1. The end of the female connector 1 near the male connector is fixedly connected to an elastic buckle 4 on the outside of the plug-in part 11. The outer peripheral wall of the connector 2 is provided with a plug-in channel 5 for the elastic buckle 4 to be inserted and parallel to the axis of the male connector. The plug-in channel 5 is provided with a limiting member 51 for preventing the elastic buckle 4 from disengaging from the plug-in channel 5. The limiting member 51 has a through groove in the middle and communicates with the plug-in channel 5. The innermost part of the plug-in channel 5 is movably connected to a button 6, and the bottom of the button 6 abuts against the surface of the elastic buckle 4. The top surface of the elastic buckle 4 is provided with a limiting part 41 extending radially outward along the female head 1. The cross-section of the limiting part 41 is U-shaped, thus forming a limiting groove 411. A limiting part 511 is integrally formed on the top wall of the groove. When the elastic buckle 4 passes through the groove, the elastic buckle 4, through its own elasticity, causes the limiting part 511 to extend into the limiting groove 411, and the end of the limiting part 511 fits against the inner wall of the limiting groove 411, thereby completing the limiting function. The end of the limiting part 41 facing away from the female head 1 has an inclined guide surface, which makes it easier for the elastic buckle 4 to be inserted into the limiting part 51. The cross-section of the limiting part 41 is U-shaped, which creates a gap between the two sides of the limiting part 511 and the inner wall of the through groove, and the cross-section of the through groove is also U-shaped. When the elastic buckle 4 passes through the through groove, it returns to its original state through its own elasticity, making it easier and more stable for the limiting part 511 to extend into the limiting groove 411. The limiting part 41 not only contacts the limiting part 511, but also contacts the inner wall of the limiting member 51, thus ensuring the contact area and making the relative fixation between the limiting part 41 and the limiting member 51 more stable, ensuring the insertion effect of the male and female heads 1. like Figures 3-6 As shown, a protrusion 21 with external threads on its outer peripheral wall is integrally formed at the middle of the end of the connector 2 facing the body 3. The body 3 is fitted onto the outer peripheral wall of the protrusion 21 and threadedly connected. A support ring 61 is also fitted onto the protrusion 21, located between the body 3 and the connector 2. The button 6 is integrally formed on the outer peripheral wall of the support ring 61. Both the button 6 and the support ring 61 are made of plastic, giving the button 6 integral elasticity. After the body 3 is threadedly connected using the support ring 61, the end of the body 3 abuts against the support ring 61, thus completing the detachable connection between the button 6 and the connector 2. The button 6 extends upward toward the insertion channel 5 and has a pressing part 62 integrally formed at its bottom. A sliding part 63 is also symmetrically arranged at the bottom of the button 6, extending toward the insertion channel 5. A limiting block 631 is provided on the side of the sliding part 63 facing the limiting member 51. A protrusion 52 that cooperates with the limiting block 631 is provided on the inner wall of the insertion channel 5 on the side of the limiting member 51 away from the connector 2. The bottom surface of the protrusion 52 abuts against the top surface of the limiting block 631, which can effectively prevent the button 6 from disengaging from the limiting port radially along the connector 2, thus affecting the subsequent pressing effect. Moreover, there is a gap between the bottom end of the sliding part 63 and the inner bottom wall of the insertion channel 5, which can facilitate the pressing of the button 6. When pressed, the pressing part 62 can fit with the elastic buckle 4 until the elastic buckle 4 is deformed and the limiting part 511 releases the material limiting groove 411. At this time, it is easier to pull the elastic buckle 4 out of the insertion channel 5, thereby completing the separation of the male and female heads 1, making the operation more convenient.

[0020] Working principle: When connecting the female connector 1 and the male connector, bring the male connector close to the female connector 1 so that the position and direction of the male connector's insertion interface 22 correspond to the insertion part 11 of the female connector 1. The guide surface on the limiting part 511 at the end of the elastic buckle 4 first contacts the groove wall of the insertion channel 5. Continue to insert. Through the guiding action of the guide surface, the elastic buckle 4 deforms, and the elastic buckle 4 can be easily inserted into the insertion channel 5 until it is fully inserted. At this time, the position of the limiting part 511 corresponds to the limiting groove 411. The elastic buckle 4 is not affected by external force and returns to its original state through its own elasticity, so that the limiting part 511 is inserted into the limiting groove 411, completing the insertion of the male connector and the female connector 1. This prevents the male connector and the female connector 1 from moving away from each other, making the connection more convenient. When disassembly is required, press button 6. Pressing part 62 can fit with elastic buckle 4 until elastic buckle 4 is deformed. Restricting part 511 releases material restriction groove 411. At this time, it is easier to pull elastic buckle 4 out of insertion channel 5, thereby completing the separation of male and female head 1, making the operation more convenient.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
