Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a push-button connector. Background Technology

[0002] Connectors generally refer to electrical connectors, which are devices that connect two active devices for transmitting current or signals. Existing connectors typically include a male plug and a female plug. After mating, the male and female plugs are locked together by a locking structure to prevent loosening during use. The locking structure, as disclosed in patent 2020225482841, includes a slot on the female plug and a latch on the male plug. The slot has a latching tongue, and the middle of the latch is rotatably mounted on the male plug via a pivot. One end of the latch has a hook that engages with the latching tongue, and the other end of the latch is connected to the male plug by a spring. When the male and female plugs are connected, the hook, under the action of the spring, is positioned in the slot and engages with the latching tongue, locking the male and female plugs together. When the user presses the pressing end of the latch, the spring is compressed, the hook of the latch rises and disengages from the latching tongue, releasing the lock between the male and female plugs, allowing the user to remove the male plug. The drawback of this locking structure is that, because the buckle is rotated and installed on the male plug, the user can easily touch the pressing end of the buckle during use, which makes it easy for the hook and the tongue to separate, and thus the male plug and the female plug to separate, and the reliability of the connection between the male plug and the female plug cannot be guaranteed. Summary of the Invention

[0003] The purpose of this invention is to provide a button-type connector that can solve the technical problems mentioned in the background art.

[0009] Preferably, the button has a flexible mechanism mounting groove facing the opening of the movable groove, and the flexible mechanism is mounted in the flexible mechanism mounting groove.

[0010] Preferably, the movable groove has an opening on the side facing the female connector, and the bottom of the movable groove has limiting grooves on both sides of its opening. The button has limiting protrusions on both sides. The button is installed in the movable groove from the opening of the movable groove, and the limiting protrusions are installed in the limiting groove. The limiting protrusions can reciprocate in the limiting groove along the pressing direction. The side wall of the movable groove has a first hole, and the button has a second hole opposite to the first hole. One of the first hole and the second hole is a strip hole, and the length direction of the strip hole is the same as the pressing direction. A pin passes through the first hole and the second hole.

[0011] Preferably, the female connector is provided with a foolproof protrusion, which is provided with a female locking groove that opens toward the male connector. The female locking groove allows the male locking part to reciprocate within it in the pressing direction. The female locking part is a female locking hole provided on the side wall of the female locking groove. The male connector has a foolproof groove that matches the foolproof protrusion on the outside of the movable groove. The male connector is an elastic buckle that extends outward from one side of the button.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1-11 As shown, this utility model provides a button-type connector, including a male connector 1 and a female connector 2 that are mutually plugged in. The female connector 2 is provided with a female locking part 3. The outer wall of the male connector 1 is recessed with a movable groove 4. A button 5 that can move relative to the movable groove 4 along the pressing direction is provided in the movable groove 4. The outer end of the button 5 extends out of the movable groove 4 and forms a pressing part 6. The pressing part 6 is provided with anti-slip texture. An elastic mechanism 7 is provided between the movable groove 4 and the button 5. The button 5 is provided with a male locking part 8 that cooperates with the female locking part 3. When the male connector 1 and the female connector 2 are plugged into each other, the button 5 is in a latched position under the restoring force of the elastic mechanism 7, so that the male latching part 8 is latched onto the female latching part 3, thereby fixing the male connector 1 and the female connector 2 together. When the button 5 is pressed, the button 5 moves relative to the movable groove 4 in the pressing direction to be in the unlocked position, the elastic mechanism 7 deforms, the male latching part 8 and the female latching part 3 are unlocked, and the male connector 1 can be pulled out from the female connector 2.

[0028] The button 5 of this invention can only move in the movable groove 4 along the pressing direction. During use, accidentally touching any part of the button 5 will not cause the button 5 to move. Only when the entire part of the button 5 is pressed on the pressing part 6 can the button 5 move and the male end locking part 8 and the female end locking part 3 be unlocked. This makes the connection between the male end connector 1 and the female end connector 2 highly reliable.

[0029] Preferably, the elastic mechanism 7 can be a spring sheet. Specifically, the spring sheet includes an elastic portion capable of elastic deformation, a first support portion located at one end of the elastic portion and supported on the button 5, and a second support portion located at the other end of the elastic portion and supported on the movable groove 4. The first support portion supports the button 5, and the second support portion supports the movable groove 4. When the button 5 is pressed, the elastic portion can undergo elastic deformation; when the button 5 is released, the elastic portion has a restoring force to reset the button 5. The spring sheet can be an S-shaped spring sheet, with one end being the first support portion and the other end being the second support portion. The middle portion of the S-shaped spring sheet can undergo elastic deformation. Alternatively, as... Figure 3 , Figure 4 As shown, the spring is composed of two symmetrically arranged S-shaped springs, with one end of the two S-shaped springs connected to form the first support portion, and the other end of the two S-shaped springs forming the second support portion. The two S-shaped springs have a certain elasticity; when button 5 is pressed, the two S-shaped springs are flattened, and when button 5 is released, the two S-shaped springs cause button 5 to return to its original position. The outer end of the second support portion can be bent downwards at an angle. During the pressing of button 5, the outer end of the second support portion is bent to prevent it from scratching surrounding components and to avoid any jamming sensation, making operation smoother. Alternatively, the spring can be a C-shaped spring, with one end forming the first support portion and the other end forming the second support portion. The middle part of the C-shaped spring can undergo elastic deformation. Alternatively, the spring can be composed of two symmetrically arranged C-shaped springs, with one end of the two C-shaped springs connected to form the first support portion, and the other end of the two C-shaped springs forming the second support portion. Generally, the two C-shaped springs are arranged opposite each other. The spring can also be O-shaped or other shapes, as long as it has enough elasticity to allow button 5 to return to its original position. The outer surfaces of the first and second support parts can be made into flat surfaces, so that the contact area with button 5 and movable groove 4 is larger, and button 5 will not deflect when pressed.

[0030] Alternatively, the elastic mechanism 7 can be a spring, supported between the button 5 and the movable groove 4. When the button 5 is pressed, the spring is compressed and deformed; when the button 5 is released, the spring returns the button 5 to its original position. Generally, two springs can be used, such as... Figure 5As shown, two springs can be set on both sides between button 5 and movable groove 4. The two springs can provide sufficient restoring force to reset button 5. The two springs are set on both sides to avoid accidental touch. That is, if only one side of button 5 is pressed, only one spring will be compressed and deformed, while the other spring will not be compressed and deformed. Then button 5 will not move, and the male end locking part 8 and the female end locking part 3 will not be unlocked.

[0031] Alternatively, the elastic structure 7 can be a tension spring, positioned between the movable groove and the button. When the button is pressed, the tension spring is stretched and deformed; when the button is released, the tension spring returns the button to its original position. Generally, two tension springs can be used, positioned on both sides between the button and the movable groove. These two springs provide sufficient restoring force to return the button to its original position. Positioning the two springs on both sides prevents accidental presses; if only one side of the button is pressed, only one tension spring is stretched and deformed, while the other remains unstretched. This prevents the button from translating and ensures the male and female locking parts will not disengage.

[0032] Preferably, the button 5 is provided with an elastic mechanism mounting groove 9 that opens toward the movable groove 4, and the elastic mechanism 7 is mounted in the elastic mechanism mounting groove 9.

[0033] Preferably, the movable groove 4 has an opening on the side facing the female connector 2. The bottom of the movable groove 4 has limiting grooves 10 on both sides of its opening. The button 5 has limiting protrusions 11 on both sides. The button 5 is installed in the movable groove 4 from the opening of the movable groove 4. The limiting protrusions 11 are installed in the limiting grooves 10 and can reciprocate in the limiting grooves 10 along the pressing direction. The side wall of the movable groove 4 has a first hole 12. The button 5 has a second hole 13 opposite to the first hole 12. One of the first hole 12 and the second hole 13 is a strip hole. The length direction of the strip hole is the same as the pressing direction. A pin 14 passes through the first hole 12 and the second hole 13. The button 5 moves in the limiting groove 10 via the limiting protrusion 11 to limit the back-and-forth travel of the button in the pressing direction. The pin 14 is installed in the first hole 12 and the second hole 13 to prevent the button 5 from running out of the opening of the movable groove 4. One of the first hole 12 and the second hole 13 is a strip hole. The pin 14 moves along the strip hole to guide the button 5 to move back and forth in the movable groove 4 in the pressing direction.

[0034] Preferably, the female connector 2 is provided with a foolproof protrusion 15, which is provided with a female end snap-fit ​​groove 16 that opens toward the male connector 1. The female end snap-fit ​​groove 16 allows the male end snap-fit ​​part 8 to reciprocate within it in the pressing direction. The female end snap-fit ​​part 3 is a female end snap-fit ​​hole provided on the side wall of the female end snap-fit ​​groove 16. The male connector 1 is provided with a foolproof groove 17 that matches the foolproof protrusion 15 on the outside of the movable groove 4. The male snap-fit ​​part 8 is an elastic buckle that extends outward from one side of the button 5. The elastic buckle is located in the foolproof groove 17 and can move in the foolproof groove 17 along the pressing direction. When the male connector 1 and the female connector 2 are inserted into each other, the anti-misalignment protrusion 15 is inserted into the anti-misalignment groove 17 to prevent incorrect insertion. After the elastic buckle extends into the female end locking groove 16, it moves in the opposite direction of the pressing direction under the action of the elastic mechanism 7 and then locks into the female end locking hole. The elastic mechanism 7 provides sufficient force to firmly lock the elastic buckle in the female end locking hole. After pressing the button 5, the button 5 moves horizontally towards the bottom end of the movable groove 4, and the elastic buckle also moves horizontally and disengages from the female end locking hole into the female end locking groove 16, thus separating the female connector 2 from the male connector 1.

[0035] As a preferred option, such as Figure 6 , Figure 7As shown, the male connector 1 includes a male connector housing 18, a male connector inner core 19, and a tailstock 20. A button 5 is mounted on the male connector housing 18. The male connector housing 18 has a first receiving cavity 21. A first retaining ring 22 is provided on the front inner wall of the first receiving cavity 21, and the first retaining ring 22 has a foolproof notch 23. An internal thread 24 is provided on the rear inner wall of the first receiving cavity 21. A second retaining ring 25 and a foolproof protrusion 26 located in front of the second retaining ring 25 are provided on the outer wall of the male connector inner core 19. The foolproof protrusion 26 matches the foolproof notch 23. The tailstock 20 has a second receiving cavity 27. An external thread 28 matching the internal thread 24 is provided on the outer wall of the middle portion of the tailstock 20. The male connector inner core 19 is then inserted into the first receiving cavity 28. The rear end of the receiving cavity 21 is inserted into the first receiving cavity 21 until the anti-fooling protrusion 26 is inserted into the anti-fooling notch 23. The front side of the second retaining ring 25 abuts against the rear side of the first retaining ring 22. Then, the tail seat 20 is inserted into the first receiving cavity 21 from the rear end of the first receiving cavity 21. At the same time, the tail of the male connector inner core 19 is inserted into the second receiving cavity 27 from the front end of the second receiving cavity 27. The outer wall of the male connector inner core 19 contacts the inner wall of the second receiving cavity 27, but the male connector inner core 19 can rotate relative to the tail seat 20. Then, the tail seat 20 is twisted until the front end of the tail seat 20 abuts against the rear side of the second retaining ring 25. The internal thread 24 and the external thread 28 cooperate to fix the tail seat 20 and the male connector housing 18 together. Traditional connectors use a two-sided insertion method, where the connector core is inserted from the front of the connector housing and the tailstock is inserted from the rear. The tailstock and connector core are connected by threads. When inserting the connector core, a clip on the connector housing must be held down, making installation inconvenient. This invention uses a rear-end insertion method, where the male connector core 19 and tailstock 20 are sequentially inserted from the rear of the male connector housing 18. The anti-misalignment protrusion 26 and anti-misalignment notch 23 prevent incorrect installation. The first retaining ring 22 and the second retaining ring 25 ensure the correct positions of the male connector core 19 and tailstock 20 within the male connector housing 18. The tailstock 20 is then fixed to the male connector housing 18 by the engagement of the internal thread 24 and the external thread 28. The second retaining ring 25 is positioned between the tailstock 20 and the first retaining ring 22, thus securing the male connector core 19 within the male connector housing 18. This method is convenient and reliable.

[0036] As a preferred option, such as Figure 1 , Figure 2 , Figure 3 As shown, the female connector 2 is provided with a connecting flange 29, which is used to fix the female connector 2 to the panel. Alternatively, as... Figure 9As shown, the female connector 2 is provided with a connecting thread 30, and a locking nut 31 is provided on the connecting thread 30. After the connecting thread 30 passes through the panel, the locking nut 31 is tightened to fix the female connector 2 to the panel. Alternatively, as... Figure 10 , Figure 11 As shown, the female connector 2 has a connecting thread 30, and a locking nut 32 is provided on the connecting thread 30. The locking nut 32 secures the cable to the female connector 2. All three types of female connectors can be used with male connectors and are applicable to various situations.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
