Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a connector that is easy to plug in and can be automatically withdrawn. Background Technology

[0002] Connectors are common components in electronic engineering. They are very common electrical connectors used to connect circuits or communication devices. They bridge the gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. They are also key components for current or signal connections.

[0003] Connectors typically provide a connection path through male and female terminals, connecting two active devices to transmit current or signals. To achieve a secure connection, most existing connectors rely on friction to connect the male and female terminals. The sliding friction between the male and female terminals ensures a stable connection between the conductive plates. However, this requires considerable force to insert and remove the connector, which is not only laborious but also prone to damaging the joint.

[0004] Furthermore, to prevent the plug from being accidentally pulled out of the socket, existing technologies typically use locking or snap-fit ​​devices to secure the plug. For example, a groove is provided in the socket, and a hook is placed in the plug. The plug is manually pressed to release the hook, and then the plug is inserted into the socket. The hook is then released to engage in the groove, securing the plug and socket. However, while this method secures the plug, removing it requires significant horizontal force to press the plug and disengage the hook from the groove, while simultaneously applying vertical force to pull it out. To ensure a reliable connection, the pull-out force between the plug and socket is generally substantial, resulting in a large vertical force. Therefore, this connector securing method is inconvenient to operate, requiring the user to apply force in both directions simultaneously (horizontal pressing and vertical pulling). Secondly, it requires considerable force, making it extremely difficult to use. Additionally, the instability of manual force can affect the connector's lifespan. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a connector that is easy to plug in and can be automatically withdrawn, so as to make it easy and effortless for the connector plug to withdraw from the connector socket.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a connector that is easy to plug in and can be automatically withdrawn.

[0007] Includes connector sockets and connector plugs;

[0008] The connector seat includes an annular first sidewall and a release slider. The first sidewall has a fixing notch, and the release slider faces the fixing notch and can slide in a direction close to or away from the fixing notch.

[0009] The connector plug includes a release post and an annular outer wall. The surface enclosed by the inner circumference of the outer wall can cover the surface enclosed by the outer circumference of the first side wall. The portion of the outer wall facing the fixing notch has a latch that can extend into the fixing notch.

[0010] As the connector plug is inserted into the connector socket, when the connector plug is inserted into the connector socket to a first depth, the latch is inserted into the fixing notch, and the exit slider abuts against the latch at one end toward the fixing notch. When the first depth is exceeded, the exit post forces the exit slider to slide toward the fixing notch, and when the second depth is reached, the latch is pushed out of the fixing notch.

[0011] The beneficial effects of the present invention are as follows: a connector that is easy to plug in and can automatically retract, wherein when the connector plug and the connector seat are inserted into the position, the latch is inserted into the fixing notch to fix the connector plug and the connector seat. When it is necessary to release the fixing of the connector seat and the connector plug, the connector plug is continued to be inserted into the connector seat, forcing the retraction slider to move towards the fixing notch, abutting the latch, and forcing the latch to retract from the fixing notch, thereby releasing the fixing of the connector plug and the connector seat.

[0019] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] Please refer to Figure 1-5 A connector that is easy to plug in and can be automatically withdrawn.

[0021] Includes connector sockets and connector plugs;

[0022] The connector seat includes an annular first sidewall and a release slider. The first sidewall has a fixing notch, and the release slider faces the fixing notch and can slide in a direction close to or away from the fixing notch.

[0023] The connector plug includes a release post and an annular outer wall. The surface enclosed by the inner circumference of the outer wall can cover the surface enclosed by the outer circumference of the first side wall. The portion of the outer wall facing the fixing notch has a latch that can extend into the fixing notch.

[0024] As the connector plug is inserted into the connector socket, when the connector plug is inserted into the connector socket to a first depth, the latch is inserted into the fixing notch, and the exit slider abuts against the latch at one end toward the fixing notch. When the first depth is exceeded, the exit post forces the exit slider to slide toward the fixing notch, and when the second depth is reached, the latch is pushed out of the fixing notch.

[0025] As can be seen from the above description, the beneficial effects of the present invention are as follows: a connector that is easy to plug in and can automatically retract, wherein when the connector plug and the connector seat are inserted into the position, the latch is inserted into the fixing notch to fix the connector plug and the connector seat; when it is necessary to release the fixing of the connector seat and the connector plug, the connector plug is further inserted into the connector seat, forcing the retraction slider to move towards the fixing notch, abutting against the latch, and forcing the latch to retract from the fixing notch, thereby releasing the fixing of the connector plug and the connector seat.

[0026] Furthermore, the sidewall includes an annular first sidewall and a second sidewall, the fixing notch is opened on the first sidewall, the first sidewall, the second sidewall and the bottom form a receiving groove, and the exit slider is located in the receiving groove.

[0027] As described above, the receiving groove can limit the exiting slider to prevent it from getting too close to or away from the fixed notch.

[0028] Furthermore, the end of the ejection slider near the bottom of the connector seat abuts against the bottom of the connector seat, and the ejection slider abuts against the edge of the fixing notch away from the bottom of the connector seat.

[0029] As described above, this ensures that the slider cannot move in directions away from or near the bottom.

[0030] Furthermore,

[0031] The ejection slider includes a vertical part, a seat wedge part, and an ejection part. The vertical part is perpendicular to the bottom of the connector seat. One end of the vertical part abuts against the bottom of the connector seat, and the other end is connected to the ejection part through the seat wedge part. The ejection part is parallel to the bottom of the connector seat. One end of the ejection part is connected to the seat wedge part, and the other end extends into the fixing notch of the first side wall and abuts against the side of the fixing notch away from the bottom of the connector seat.

[0032] The exit post faces the exit slider, and the end of the exit post facing the exit slider has a plug wedge. As the connector plug is inserted into the connector seat, the plug wedge presses against the seat wedge to make the exit slider slide toward the fixed notch.

[0033] As described above, the specific structure of the exit slider is given, which enables the exit pin to force the exit slider to slide toward the fixed notch.

[0034] Furthermore, the exit slider includes at least one spring, with one end of the spring abutting against the first sidewall and the other end abutting against the vertical part.

[0035] As can be seen from the above description, this allows the exit slider to automatically reset and the whole thing to feel mechanical.

[0036] Furthermore, the connector plug also includes a limiting post, the length of which limits the connector plug from being over-inserted into the connector socket.

[0037] As described above, it is important to prevent the connector plug from being over-inserted into the connector socket, which could damage the connector.

[0038] Furthermore, the connector seat has a limiting slider facing the limiting post, and the first sidewall and the second sidewall have limiting notches facing the limiting slider. The limiting slider includes a U-shaped guide groove, and the two ends of the groove wall of the U-shaped guide groove bend towards the limiting notches of the first sidewall and the second sidewall respectively and penetrate into the limiting notches.

[0039] As described above, the limiting slider extends into the limiting notch to fix the distance of the limiting slider in the direction of approaching and away from the bottom, and the U-shape restricts it within the first and second side walls.

[0040] Furthermore,

[0041] The opening of the U-shaped guide groove faces the bottom of the connector seat. The limiting slider also includes at least one spring. One end of the spring of the limiting slider extends into the U-shaped guide groove and abuts against the U-shaped guide groove, and the other end is connected to the bottom of the connector seat.

[0042] The connector seat has a number of guide posts that are the same as the number of springs in the limiting slider. The guide posts are inserted into each spring of the limiting slider, and when the end of the guide post away from the bottom of the connector seat abuts against the bottom of the U-shaped guide groove, the U-shaped guide groove abuts against the edge of the limiting notch near the bottom of the connector seat.

[0043] As can be seen from the above description, the spring not only enables the automatic reset of the limit slider, but also provides auxiliary force when the connector plug is withdrawn.

[0044] Furthermore, there are two fixed notches, located on opposite sides of the first sidewall; there are two exit sliders, each facing one of the two fixed interfaces; there are two exit posts, each corresponding to one exit slider; there are two latches, each facing one fixed notch; there are two limiting sliders, located on opposite sides of the connector seat; and there are two limiting posts, each corresponding to one limiting slider.

[0045] As can be seen from the above description, the relative design not only makes the force more even, but also allows it to still function after rotating 180 degrees.

[0046] Furthermore, the first sidewall, the second sidewall, and the outer wall are all rectangular, and the inner periphery of the outer wall is the same size and shape as the outer periphery of the first sidewall.

[0047] As can be seen from the above description, long hair has a foolproof function.

[0048] The present invention provides a connector that is easy to plug in and can be automatically withdrawn, suitable for various electrical connection scenarios.

[0049] Please refer to Figure 1-5 Embodiment 1 of the present invention is as follows:

[0050] A connector that is easy to plug in and can automatically retract includes a connector base and a connector plug. The connector base includes a retraction slider group and a limiting slider group. The retraction slider group includes a first retraction slider 31 and a second retraction slider 32. The limiting slider group includes a first limiting slider 41 and a second limiting slider 42. The connector base includes a bottom, a coaxial square first sidewall 1 and a square second sidewall 2. The second sidewall 2 is located inside the first sidewall 1. The retraction slider group and the limiting slider group are both located between the first sidewall 1 and the second sidewall 2, so that the first sidewall 1, the second sidewall 2 and the bottom form a receiving groove.

[0051] The first exit slider 31 and the second limiting slider 42 are located at the two long sides of the connector seat, respectively, and the first limiting slider 41 and the second limiting slider 42 are located at the two short sides of the connector seat. The portion of the first sidewall 1 facing the first exit slider 31 and the second exit slider 32 has an elongated fixing notch with the same length as the first exit slider 31 and the second exit slider 32. The portions of the first sidewall 1 and the second sidewall 2 facing the first limiting slider 41 and the second limiting slider 42 have elongated limiting notches with the same length as the first limiting slider 41 and the second limiting slider 42.

[0052] Please refer to Figure 2-3 The first exit slider 31 and the second exit slider 32 include a vertical part, a seat wedge part, and an exit part. The vertical part is a vertically placed long plate, and its side facing the first sidewall 1 is connected to the first sidewall 1 by one or more springs. The springs force the vertical part to abut against the first sidewall 1 in the normal state. One end of the vertical part abuts against the bottom, and the other end is connected to the exit part through the seat wedge part. The exit part is a horizontal plate, one end of which is connected to the seat wedge part, and the other end extends into the fixing notch of the first sidewall 1. The side of the exit part away from the bottom abuts against the side of the fixing notch of the first sidewall 1 away from the bottom. The abutment between the vertical part and the bottom and the abutment between the exit part and the fixing notch enable the first slider and the second slider as a whole to slide only along the elastic direction of the spring.

[0053] It is worth noting that the spring in this embodiment is not necessary; the elasticity of the connector plug can also be used to return the exit slider to its original position.

[0054] The connector plug includes a bottom and a square outer wall 51. The surface enclosed by the inner wall of the outer wall 51 can cover the surface enclosed by the outer wall 51 of the first side wall 1. The connector plug has an exit post 52 perpendicular to the bottom of the connector, facing the first exit slider 31 and the second exit slider 32. The end of the exit post 52 away from the bottom of the connector plug has a plug beveled wedge surface. During the insertion of the connector plug into the socket, the plug beveled wedge surface abuts against the socket beveled wedge surface. The outer wall 51 of the connector plug faces the fixing notch, and the end away from the bottom of the connector plug is bent inward to serve as a latch 511. When the connector plug and the connector socket are inserted into place, the latch 511 is inserted into the fixing notch to fix the connector plug and the connector socket.

[0055] When it is necessary to release the connector socket and connector plug from the fixing, the connector plug is continued to be inserted into the connector socket, so that the wedge surface of the plug abuts against the wedge surface of the socket, forcing the first exit slider 31 and the second exit slider 32 to move toward the fixing notch, abut against the latch 511, and forcing the latch 511 to exit the fixing notch, so as to release the fixing of the connector plug and the connector socket.

[0056] Please refer to Figure 4-5The second limiting slider 42 of the first limiting slider 41 includes a U-shaped guide groove. The opening of the U-shaped guide groove faces the bottom of the connector seat. The two ends of the groove wall of the U-shaped guide groove bend towards the limiting notch of the first side wall 1 and the limiting notch of the second side wall 2, respectively, and penetrate into the limiting notch. The bottom of the U-shaped guide groove is connected to the bottom of the connector seat by one or more springs. The part of the connector plug facing the first limiting slider 41 and the second limiting slider 42 has a limiting post 53. When the connector plug is inserted into the connector seat, the limiting post 53 abuts against the limiting slider and forces the limiting slider to move towards the bottom of the connector seat. When the U-shaped guide groove abuts against the side of the limiting notch of the first side wall 1 and the second side wall 2 near the bottom of the connector seat, the limiting is achieved, preventing the connector plug from being over-inserted into the connector seat.

[0057] The connector seat is provided with a guide post at the location of the first limiting slider 41 and the second limiting slider 42 spring. The guide post is inserted into the spring to prevent the spring from bending and to achieve guidance. The length of the guide post is limited such that when the U-shaped guide groove abuts against the side of the limiting notch of the first side wall 1 and the second side wall 2 near the bottom of the connector seat, the bottom of the U-shaped groove just contacts the limiting post 53 or does not contact the limiting post 53.

[0058] In summary, the present invention provides a connector that is easy to insert and can automatically retract. When the connector plug and connector socket are inserted into the correct position, the latch is inserted into the fixing notch to fix the connector plug and connector socket. When it is necessary to release the fixing of the connector socket and connector plug, the connector plug is further inserted into the connector socket, forcing the retraction slider to move towards the fixing notch, abutting the latch, and forcing the latch to retract from the fixing notch, thereby releasing the fixing of the connector plug and connector socket.

[0059] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
