Description

Technical Field

[0001] This invention belongs to the field of connector unlocking technology, and more specifically, relates to a connector unlocking structure and a wire end connector. Background Technology

[0002] To maintain connector mating stability, connectors are often equipped with locking latches. When the connectors are mated, the latches lock the two mated connectors in place, preventing shaking, poor contact, and other issues. These latches are typically elastic, using their own deformation to lock and unlock. Traditional elastic latches can be unlocked by pinching the operating end with a finger to cause elastic deformation, or by attaching a pull strap to the operating end. The pull strap passes through a guide hole and extends upwards; pulling the strap causes elastic deformation of the operating end of the elastic latch, thus unlocking it. However, both unlocking methods require sufficient operating space above the connector. In practical applications, if other components or devices are located above the connector, unlocking becomes inconvenient, and removing the connector becomes difficult. Summary of the Invention

[0034] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] like Figures 1 to 4 As shown, the present invention provides a connector unlocking structure, wherein a resilient latch 1 is provided on one side of the connector, comprising:

[0036] Cover plate 2 is disposed above the connector. A groove 3 extending along the length of cover plate 2 is formed between cover plate 2 and connector body. A first slider 4 is slidably disposed in the groove 3. Cover plate 2 has a through groove 5.

[0037] The second slider 6 is slidably disposed on the outside of the cover plate 2. The second slider 6 is connected to the first slider 4 through the connecting part 7 of the through slot 5. Part of the second slider 6 is disposed on the outside of the operating end of the elastic latch 1 away from the connector. The second slider 6 and the operating end of the elastic latch 1 are connected by a transmission structure. The transmission structure can push the operating end of the elastic latch 1 to move closer to the connector when the second part slides along the length direction of the cover plate 2.

[0038] The pull strap 8 is connected to one end of the first slider 4 in the sliding direction and extends outward from the end face of the connector.

[0039] Specifically, to address the problem of inconvenient connector unlocking and difficult removal when other components or devices are located above the connector in existing technologies, the connector unlocking structure provided by this invention features a cover plate 2 above the connector, forming a groove 3 above the connector. A first slider 4 can slide within the groove 3 along the length of the connector. A pull strap 8 is connected to one end of the first slider 4 in the sliding direction. The pull strap 8 extends from the end face of the connector. Pulling the pull strap 8 outward can drive the first slider 4 and, through the connection of the connecting part 7, slide together with the second slider 6 along the length of the connector. A transmission structure enables the transmission between the second slider 6 and the operating end of the elastic latch 1. Under the action of the transmission structure, when the second slider 6 moves, it pushes the operating end of the elastic latch 1 towards the connector, causing the elastic latch 1 to undergo elastic deformation, thereby unlocking. In this way, pulling the pull strap 8 in an upward direction from the outside of the connector's end face can unlock and remove the connector upwards, eliminating the need for sufficient operating space above the top surface of the connector. This facilitates the unlocking and removal of the connector even when components or devices are located above it.

[0040] Furthermore, when there is sufficient operating space above the connector, the connector can also be unlocked by laterally moving the second slider 6, providing another way to unlock the connector.

[0041] Optionally, it also includes a spring-loaded structure connected to the first slider 4 and / or the second slider 6. The spring-loaded structure is used to apply a spring-loaded force to the first slider 4 and / or the second slider 6 in the opposite direction to the sliding caused by the pull of the strap 8.

[0042] Specifically, the spring-loaded structure can provide spring-loaded force to the first slider 4 and / or the second slider 6, so that after the pull strap 8 pulls to unlock and pulls out, the first slider 4 and the second slider 6 can automatically reset, assisting the elastic deformation recovery of the elastic lock 1 after unlocking.

[0043] Optionally, the connector includes a top surface, a bottom surface, two opposite sides, and two opposite end faces. An elastic latch 1 is disposed on one side of the connector, a pull strap 8 is disposed on one end face of the connector, and a groove 3 extends along the two end faces of the connector to allow the first slider 4 and the second slider 6 to slide between the two end faces of the connector.

[0044] Specifically, taking the vertical insertion and removal of the connector as an example, along the insertion and removal direction of the connector, the top is the top surface, the bottom is the bottom surface, and the four sides are two opposite side surfaces and two opposite end surfaces. The side surfaces are the large surfaces in the length direction of the connector, and the end surfaces are the small surfaces in the width direction of the connector. The pull strap 8 is pulled along the length direction of the connector so that the first slider 4 and the second slider 6 slide along the length direction of the connector. The second slider 6 pushes the operating end of the elastic locking buckle 1 to move in the width direction of the connector through the transmission structure.

[0045] Optionally, the transmission structure includes a protrusion 9 and a recess 10. One of the operating ends of the second slider 6 and the elastic latch 1 is provided with the protrusion 9, and the other is provided with the recess 10. The sidewall of the protrusion 9 and the sidewall of the recess 10 are in inclined contact.

[0046] Specifically, the transmission structure engages the second slider 6 with the operating end of the elastic latch 1 through the guide surfaces of the side walls of the protrusion 9 and the recess 10. When the first slider 4 slides, it drives the second slider 6 to slide. The second slider 6 applies a component force perpendicular to the sliding direction of the second slider 6 to the operating end of the elastic latch 1, thereby pushing the operating end of the elastic latch 1 to move away from the second slider 6.

[0047] Optionally, the springback structure includes a spring piece 11, which is disposed between the cover plate 2 and the first slider 4.

[0048] Specifically, the spring piece 11 is in a pre-compressed state, with both ends of the spring piece 11 contacting the cover plate 2 and the first slider 4 respectively, thereby applying a rebound force to the first slider 4. When the pull strap 8 pulls the first slider 4, the movement of the first slider 4 further compresses the spring piece 11. After the pulling ends, the spring piece 11 releases its elastic force, causing the first slider 4 to return to its original position.

[0049] Optionally, a groove 12 is provided on the side of the first slider 4 near the cover plate 2, and a limiting part 13 is provided on the side of the cover plate 2 near the first slider 4. The limiting part 13 extends into the groove 12 and divides the groove 12 into two mounting slots, and a V-shaped spring piece 11 is provided in each of the two mounting slots.

[0050] Specifically, the two spring pieces 11 allow the first slider 4 to slide to both ends, both of which can achieve a rebound effect.

[0051] In this embodiment, both ends of the first slider 4 in the sliding direction are provided with connection ports 14 that can be connected to the pull strap 8. The pull strap 8 can be connected at either end so that it can be unlocked and pulled out at either end of the connector.

[0052] Optionally, the slide 3 is disposed on the lower side of the cover plate 2 or on the upper side of the connector, or is formed by connecting sub-slides 3 disposed on the lower side of the cover plate 2 and the upper side of the connector respectively.

[0053] Specifically, the slide groove 3 can be set on the lower side of the cover plate 2, or on the upper side of the connector, or sub-slide grooves 3 can be set on both the lower side of the cover plate 2 and the upper side of the connector, and the cover plate 2 is fixed to the upper surface of the connector to form a complete slide groove 3.

[0054] Optionally, a sliding groove 3 is provided on the lower side of the cover plate 2, and a through groove 5 is opened at the bottom of the sliding groove 3. The through groove 5 is a guide groove extending along the extension direction of the sliding groove 3, and the connecting part 7 is a guide post.

[0055] Specifically, the slide groove 3 is located on the lower side of the cover plate 2, and the bottom of the slide groove 3 has a through groove 5 for the connecting part 7 to pass through and to accommodate the connecting part 7 to slide within the through groove 5; furthermore, the through groove 5 is a guide groove in the shape of an elongated hole, and the guide post cooperates with the guide groove.

[0056] Optionally, a first pull belt outlet 15 is provided on the end wall of the chute 3 in the extending direction.

[0057] Specifically, the pull strap 8 passes through the first pull strap outlet 15 and extends outward toward one end of the connector.

[0058] Optionally, the second slider 6 includes a first part and a second part. The first part and the second part are connected to form an L-shaped structure. The first part is slidably disposed on the upper side of the cover plate 2 and connected to the first slider 4 through the connecting part 7 of the through groove 5. The second part is slidably disposed on the outside of the operating end of the elastic latch 1 away from the connector.

[0059] Specifically, the second slider 6 has an L-shaped cross-section, is connected to the first slider 4 through the first part, and slides on the upper side of the cover plate 2. The second part is wrapped around the operating end of the elastic latch 1.

[0060] Optionally, the operating end of the elastic latch 1 is provided with two protrusions 9 that protrude in the direction away from the connector, and a groove 16 with a V-shaped inclined groove wall is formed between the two protrusions 9. The second slider 6 is provided with two recesses 10 on the side near the operating end of the elastic latch 1, and a trapezoidal protrusion 17 is formed between the two recesses 10. The trapezoidal protrusion 17 cooperates with the groove 16 with a V-shaped inclined groove wall.

[0061] In this embodiment, the outer side of the second part forms a wave shape.

[0065] Specifically, the connector unlocking structure is provided above the connector body, so that the pull strap 8 extends outward from one end of the connector. The connector can be unlocked and pulled out upward by pulling the pull strap 8 in an oblique upward direction on the outside of the end face of the connector. There is no need to leave enough operating space above the top surface of the connector. This facilitates the unlocking and removal of the connector when there are components or devices above it.

[0066] Optionally, the connector body includes an insulating housing 18, a plug-in portion 19 is provided on the lower side of the insulating housing 18, an electrical connection portion 7 extending downward is provided inside the insulating housing 18, a cable 20 is connected to the upper end of the electrical connection portion 7, a limiting connection portion 21 extending upward is provided on the upper side of the insulating housing 18, and the cover plate 2 is connected to the limiting connection portion 21.
