Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector designed to prevent loosening. Background Technology

[0002] Connectors typically consist of a housing and multiple terminals housed within the housing. By inserting a plug into the interface of the corresponding terminal, electrical devices can be connected to the connector. In everyday life, USB ports on computers, power sockets for electrical appliances, and other connectors or terminals of items that require plug-and-socket connections can all serve as connectors.

[0003] However, existing connectors, especially those using terminal interfaces, have multiple terminal interfaces, many of which are exposed. This means the connectors are not fully connected to the internal electrical components. In use, not every connector can be fully utilized, leaving some exposed to the air. Dust and moisture in the air can easily enter the electrical components through these connectors, causing them to adhere and resulting in poor contact. In severe cases, this can directly damage the connector.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a connector that prevents loosening. Utility Model Content

[0005] The purpose of this invention is to provide an anti-loosening connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connector for preventing loosening, comprising a connector electrical component, a sealing plate fixedly connected to the front end of the connector electrical component, and openings on both the left and right sides of the surface of the sealing plate, a connecting channel fixedly connected to the inner surface of the opening, the rear end of the connecting channel correspondingly communicating with the interface of the connector electrical component, and a through cavity on both the left and right sides of the front side of the inner surface of the connecting channel, and a sealing mechanism provided on both the left and right sides of the inner surface of the opening.

[0007] Preferably, the sealing mechanism includes gathering grooves on both the left and right sides of the inner surface of the passage, the size of the gathering groove openings matching the passage cavity, and the position corresponding to the passage cavity.

[0008] Preferably, the sealing mechanism further includes a thrust spring fixedly installed on the inner surface of the converging groove, and a baffle is fixedly connected to the opposite end of the thrust spring.

[0009] Preferably, the front side of the baffle is set as an inclined surface, and the connection end between the baffle and the thrust spring slides inside the convergence groove.

[0010] Preferably, the inner surface of the connecting channel has grooves on both the left and right sides of the rear side, and the rear end of the inner surface of each groove is fixedly connected with a spring plate.

[0011] Preferably, each of the spring plates has a protrusion fixedly installed at its front end, with one side of the protrusion protruding from the groove.

[0012] Preferably, the shape of the bump is set as an irregular triangle, and the angle of the front slope of the bump is greater than the angle of the rear slope.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of a through-hole, connecting channel, through cavity, sealing mechanism, gathering groove, thrust spring, and baffle, allows the unused connecting channel to be closed and sealed when the connector interface is not connected. The baffle moves towards the center of the through-hole under the action of the thrust spring, and the two side baffles, penetrating the through cavity, align with the front opening of the connecting channel, thus sealing the unused connecting channel. When in use, the connector plug is inserted into the connecting channel, and the front inclined surface pushes the baffle to move in the opposite direction and retract into the gathering groove, thereby opening the connecting channel and ensuring smooth insertion of the connector plug. Furthermore, after the plug is connected, the entire plug end is located inside the connecting channel, and the baffle, under the action of the thrust spring... The connector will continue to move towards the center, clamping the wire harness portion of the connector plug. At this time, the large end of the connector plug will be located behind the baffle, making it difficult for the connector plug to push the baffle through the right-angled surface behind the baffle. This limits the position of the connector plug, allowing it to be stably connected to the connector as a whole. When the connector is not in use, it can automatically close the unconnected socket channel, preventing dust and moisture from entering the connector through the socket channel and causing damage. Furthermore, after the connector plug is connected to the connector, it can also limit the position of the connector plug, preventing it from loosening due to external pulling force, thus greatly improving the stability of the connection between the connector and the connector plug.

[0015] 2. This utility model, through the arrangement of grooves, spring plates, and protrusions, allows the connector plug to easily push the protrusion, carrying the spring plate, into the groove when inserted into the connection channel using a large-angle inclined surface. After the connector plug is connected to the connector's electrical components, the spring plate will cause the protrusion to reset and lock onto the corresponding groove of the connector plug, thereby fixing the connection between the connector plug and the connector. Since the rear side of the protrusion is a small-angle inclined surface, a larger force needs to be applied manually, and the direction of the force must be fixed forward, in order for the connector plug to push the protrusion into the groove from the rear using the inclined surface, thus allowing the connector plug to be removed. Therefore, the limiting effect of the protrusion further improves the stability of the connector plug and connector installation, effectively preventing the connector plug and connector from becoming loose due to unspecific external pulling forces. Conversely, as long as a large directional pulling force is applied manually, the plug can be easily removed. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, an anti-loosening connector includes a connector electrical component 1. A sealing plate 2 is fixedly connected to the front end of the connector electrical component 1. Openings 3 are provided on both the left and right sides of the surface of the sealing plate 2. A connecting channel 4 is fixedly connected to the inner surface of the opening 3. The rear end of the connecting channel 4 is connected to the interface of the connector electrical component 1. A cavity 5 is provided on both the left and right sides of the front side of the inner surface of the connecting channel 4. A sealing mechanism 6 is provided on both the left and right sides of the inner surface of the opening 3.

[0022] By adopting the above technical solution, the connector plug can be inserted into the corresponding connection channel 4, and can be accurately connected to the connector interface.

[0023] Furthermore, the blocking mechanism 6 includes gathering grooves 601 on both the left and right sides of the inner surface of the opening 3. The size of the opening of the gathering grooves 601 matches that of the cavity 5 and is located corresponding to the cavity 5.

[0024] The sealing mechanism 6 also includes a thrust spring 602 fixedly installed on the inner surface of the gathering groove 601. Each opposite end of the thrust spring 602 is fixedly connected to a baffle 603. The front side of the surface of the baffle 603 is set as an inclined surface, and the connection end between the baffle 603 and the thrust spring 602 is located inside the gathering groove 601 and slides.

[0025] By adopting the above technical solution, the baffle 603 will move towards the middle of the opening 3 under the action of the thrust spring 602. The two baffles 603 pass through the cavity 5 and are located at the front opening of the connecting channel 4 to fit against each other, thereby closing and sealing the unused connecting channel 4.

[0026] When in use, the connector plug is inserted into the connector channel 4. The front inclined surface can push the baffle 603 to move in the opposite direction and retract into the gathering groove 601, thereby opening the connector channel 4 and ensuring that the connector plug can be smoothly inserted and connected. After the plug is connected, the entire plug end is located inside the connector channel 4.

[0027] Under the action of the thrust spring 602, the baffle 603 will still move towards the center, thereby clamping the wire harness part of the connector plug. At this time, the large end of the connector plug will be located on the rear side of the baffle 603. The connector plug is difficult to push the baffle 603 to move through the right angle surface on the rear side of the baffle 603, thereby limiting the connector plug and enabling the connector plug to be stably connected to the connector as a whole.

[0028] Furthermore, grooves 7 are provided on both the left and right sides of the rear side of the inner surface of the connecting channel 4, and spring plates 8 are fixedly connected to the rear end of the inner surface of the grooves 7.

[0029] Each front end of the spring plate 8 is fixedly equipped with a protrusion 9, and one side of the protrusion 9 protrudes out of the groove 7.

[0030] By adopting the above technical solution, the groove 7 can provide space for the protrusion 9 to retract, while the elastic plate 8 ensures that the protrusion 9 can move and retract, and also provides force for the protrusion 9 to reset later.

[0031] Furthermore, the shape of the bump 9 is set as an irregular triangle, and the angle of the front slope of the bump 9 is greater than the angle of the rear slope.

[0032] By adopting the above technical solution, the connector plug can easily push the protrusion 9 to carry the spring plate 8 to bend and retract into the groove 7 by utilizing the large-angle inclined surface on the side.

[0033] The rear side of the protrusion 9 is a small-angle slope. The small-angle slope requires a greater force to be applied manually, and the direction of the force must be fixed forward in order for the connector to push the protrusion 9 into the groove 7 from the rear using the slope. If the direction of the applied force is deviated, the connector will tilt and shift, and it will be impossible to effectively apply all the pulling force to make the protrusion 9 retract from the rear using the small-angle slope. Therefore, the pulling force generated by external accidental contact is not enough to make the protrusion 9 squeeze and retract from the rear, thereby preventing the connector from becoming loose.

[0034] Working Principle: When using this anti-loosening connector, firstly, when the connector plug is inserted into the connection channel 4, the front inclined surface pushes the baffle 603 to move in the opposite direction and retract into the gathering groove 601, thereby opening the connection channel 4 and ensuring that the connector plug can be smoothly inserted. When the connector plug is inserted into the connection channel 4, the connector plug can easily push the protrusion 9, carrying the spring plate 8, to bend and retract into the groove 7 using the large-angle inclined surface. After the plug is connected, the entire plug end is located inside the connection channel 4. Under the action of the thrust spring 602, the baffle 603 will still move towards the center, thereby clamping the wire harness part of the connector plug. At this time, the large end of the connector plug will be located behind the baffle 603, and the connector plug cannot push the baffle 603 to move through the right-angle surface behind the baffle 603, thereby limiting the connector plug and enabling the connector plug to be stably connected to the connector as a whole. Furthermore, the spring plate 8 will drive the protrusion 9 to reset and lock the corresponding groove of the connector plug, thereby securing the connection. The connection between the plug and the connector is fixed. Since the rear side of the protrusion 9 is a small-angle slope, a larger force needs to be applied manually, and the direction of the force must be fixed forward, so that the plug can be pushed from the rear side by the slope to retract the protrusion 9 into the groove 7. Therefore, under the influence of uneven external contact and pulling force, the plug and connector are limited by the baffle 603 and the protrusion 9, and cannot be separated. If disassembly is required, the baffle 603 needs to be manually and precisely opened, and a stable outward pulling force needs to be applied to separate the plug and connector. When the connector interface is not connected, the baffle 603 will move towards the middle of the opening 3 under the action of the thrust spring 602. The two baffles 603 through the cavity 5 and the front opening of the connection channel 4 are aligned and fitted, thereby closing and sealing the unused connection channel 4, and effectively protecting the unused connection socket. This is the working principle of the anti-loosening connector.
