Description

Technical Field

[0001] This invention relates to the field of ferrule connector technology, specifically a multi-core cable ferrule connector based on smart grids. Background Technology

[0002] In smart grid environments, ferrule connectors are typically used to enable quick plugging and unplugging of multi-core cables. They are key physical nodes for achieving efficient, reliable, and intelligent operation of modern power grids. Ferrule connectors are not only responsible for the transmission of power and signals, but also are core components for connecting smart devices. The core components of ferrule connectors include the housing and sheath, contacts (pins and sockets), and locking mechanism. The locking mechanism is used to securely lock the plug and socket, and is usually locked using a threaded connection.

[0003] In the prior art, when the pin and the pin socket are connected, the pin is inserted into the pin hole of the pin socket by fitting together. Since the inside of the pin hole of the pin socket cannot be observed, but the outer wall of the pin is easy to observe, after long-term use, when there are contaminants such as dust and oil in the pin hole, poor contact may easily occur when the pin and the pin socket are connected. Since the user cannot observe the inside of the pin hole, they may mistakenly believe that the ferrule connector is damaged and cannot continue to be used.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing ferrule connectors. Summary of the Invention

[0005] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this invention is to provide a multi-core cable ferrule connector based on a smart grid, thereby solving the problem mentioned in the background that when dust, oil, or other contaminants are present in the pinhole, poor contact easily occurs when the pin and the pin socket are inserted. Users cannot observe the inside of the pinhole and may mistakenly believe that the ferrule connector is damaged and cannot continue to be used.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-core cable ferrule connector based on a smart grid, comprising a connector socket and a connector plug, and further comprising: The pin socket and the pin are respectively located inside the connector socket and the connector plug; The insertion mechanism, located at the end of the pin socket, is used to switch different conductive contact surfaces by unidirectional rotation each time the pin socket and the pin are inserted. The inserts are fixed to the end faces of the pins, and the end of the insert near the pin seat is set as a conical structure; The insertion mechanism includes a movable column that is set at an equal angle at the end of the pin seat, and the end of the movable column is provided with an inclined arc surface structure that fits the conical surface of the insertion column at an equal angle.

[0007] Preferably, the end of the insert near the pin is configured as a cylindrical structure.

[0008] Preferably, the insertion mechanism further includes an outer ring fixed to the end of the pin seat, a fixing frame fixed to the inner wall of the outer ring, conductive seats symmetrically arranged on the outer wall of the fixing frame and slidingly engaged therewith, and a first spring located outside the fixing frame connecting the conductive seats and the inner wall of the outer ring.

[0009] Preferably, the fixing frame has a cross-shaped structure, and the outer wall of the conductive base is attached to the end face of the needle base.

[0010] Preferably, the insertion mechanism further includes a connecting cover fixed to the end face of the conductive base, the interior of the connecting cover is provided with a conductive sheet that fits against its inner wall, and a rubber ring is provided between the connecting cover and the conductive sheet.

[0011] Preferably, the insertion mechanism further includes a conductive post fixed to the outer wall of the conductive sheet and penetrating the connecting cover. The conductive post has a movable groove inside that slides with the movable post, and a second spring is provided between the movable groove and the movable post.

[0012] Preferably, the outer wall of the movable column is fixed with a sliding rod, and the inner wall of the movable groove of the conductive column is spirally provided with a sliding groove that slides with the sliding rod.

[0013] Preferably, the outer wall of the conductive column is provided with a horizontal arc surface structure at an equal angle, which corresponds to the inclined arc surface structure of the outer wall of the movable column, and the horizontal arc surface structure fits the column surface structure of the insertion column.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, during insertion, pushing the connector plug causes the pins to move towards the pin seat end. The inclined surface of the pin first pushes the movable post into the movable groove of the conductive post. While the movable post compresses the second spring, it drives the sliding rod to move. As the sliding rod moves, it drives the conductive post to rotate 90 degrees through the sliding groove. When the movable post slides to its maximum displacement under the length limit of the sliding groove, the plug is pushed to cause the conductive post at the same angle to expand outward until the horizontal arc surface of the outer wall of the conductive post moves and fits against the cylindrical surface of the plug. At this time, the insertion of the connector socket and the connector plug is completed. At this time, the movable post is in a suspended state. Under the action of the second spring, the movable post rotates by sliding the sliding rod in the sliding groove. If it is found that the circuit is not connected after insertion, the connector plug can be unplugged and reinserted into the connector socket. The above process is repeated so that the conductive post rotates 90 degrees again in the same rotation direction. Conductive power is achieved by the other horizontal arc surface of the conductive post fitting against the cylindrical surface of the plug. Thus, when poor contact occurs, different horizontal arc surfaces of the conductive post can be switched to contact the plug for conductive power. In this invention, if the horizontal arc surface circuit of the conductive post is still not conductive after switching, the outer surface of the conductive post and the plug can be cleaned first. The conductive post and the plug are exposed to the outside, which makes it easier to clean the outer surface. If the circuit is still not conductive after cleaning the outer surface of the conductive post and the plug, it can be considered that the connector is damaged, and then it can be repaired or replaced.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 8 The present invention provides a technical solution: a multi-core cable ferrule connector based on a smart grid, comprising a connector socket 1 and a connector plug 2, and further comprising: Pin socket 3 and pin 4 are respectively disposed inside connector socket 1 and connector plug 2; The insertion mechanism is located at the end of the pin holder 3 and is used to switch different conductive contact surfaces by unidirectional rotation each time the pin holder 3 and the pin 4 are inserted. The inserts 6 are fixed to the end faces of the inserts 4, and the end of the insert 6 near the needle seat 3 is set as a conical structure; The insertion mechanism includes a movable post 15 that is set at an equal angle at the end of the pin seat 3. The end of the movable post 15 is provided with an inclined arc surface structure that fits the conical surface of the insertion post 6 at an equal angle.

[0019] In practice, the ferrule connector, except for the insertion mechanism and the ferrule 6, is based on existing technology. When the inclined arc surface of the outer wall of the movable post 15 matches the conical surface of the ferrule 6, it has an inward concave characteristic, so that the ferrule 6 is limited by the inclined arc surface matching the conical surface of the ferrule 6 when it moves.

[0020] The other end of the insert 6 near the pin 4 is set as a cylindrical structure.

[0021] In practice, the insert 6 is made of conductive metal.

[0022] The insertion mechanism also includes an outer ring 5 fixed to the end of the pin seat 3. A fixing frame 7 is fixed to the inner wall of the outer ring 5. Conductive seats 8 are symmetrically arranged on the outer wall of the fixing frame 7 and slide with it. A first spring 9 located outside the fixing frame 7 is connected between the conductive seats 8 and the inner wall of the outer ring 5.

[0023] The fixing bracket 7 has a cross-shaped structure, and the outer wall of the conductive base 8 is attached to the end face of the needle base 3.

[0024] In practice, the outer wall of the conductive seat 8 is attached to the end face of the needle seat 3 to ensure that the conductive seat 8 remains conductive when it slides on the fixed frame 7.

[0025] The insertion mechanism also includes a connecting cover 10 fixed to the end face of the conductive base 8. The interior of the connecting cover 10 is provided with a conductive sheet 11 that fits against its inner wall, and a rubber ring 12 is provided between the connecting cover 10 and the conductive sheet 11.

[0026] In practice, when the conductive sheet 11 rotates, it will rotate in conjunction with the rubber ring 12. The rubber ring 12 will generate a certain resistance to the rotation of the conductive sheet 11. On the one hand, it prevents the conductive sheet 11 from rotating inside the connecting cover 10, and on the other hand, it facilitates the rotation of the movable column 15.

[0027] The insertion mechanism also includes a conductive post 13 fixed to the outer wall of the conductive sheet 11 and penetrating the connecting cover 10. The conductive post 13 has a movable groove inside that slides with the movable post 15, and a second spring 14 is provided between the movable groove and the movable post 15.

[0028] In practice, the second spring 14 is placed in the movable slot.

[0029] The outer wall of the movable column 15 is fixed with a slide rod 16, and the inner wall of the movable groove of the conductive column 13 is spirally provided with a slide groove 17 that slides and engages with the slide rod 16.

[0030] In practice, the arc of the chute 17 on the inner wall of the movable groove is ninety degrees.

[0031] The outer wall of the conductive post 13 is provided with a horizontal arc surface structure at an equal angle, which corresponds to the inclined arc surface structure of the outer wall of the movable post 15, and the horizontal arc surface structure matches the cylindrical surface structure of the insert post 6.

[0032] In practice, the conductive post 13 conducts electricity by fitting the outer wall of the insert post 6 with a horizontal arc surface structure.

[0033] Working principle: First, when the connector socket 1 and connector plug 2 are plugged in, the conical surface of the plug 6 will simultaneously fit against the inclined arc surface of the outer wall of the movable post 15, and the two will be in a fitting state. At this time, if the connector plug 2 is pushed, the pin 4 will drive the plug 6 to move closer to the end of the pin seat 3. Since the elastic force of the first spring 9 is greater than that of the second spring 14, the inclined surface of the plug 6 will first push the movable post 15 to slide into the movable groove of the conductive post 13. While the movable post 15 is squeezing the second spring 14, it will drive the slide rod 16 to move. The slide groove 17 is spirally opened on the inner wall of the movable groove, and the arc of the slide groove 17 on the inner wall of the movable groove is ninety degrees. When the slide rod 16 moves, it will drive the conductive post 13 to rotate ninety degrees through the slide groove 17. The conductive post 13 will then drive the conductive piece 11 to rotate synchronously in the connecting cover 10. When the conductive piece 11 rotates, it will fit against the rubber ring 12 and rotate. The rubber ring 12 will generate a certain resistance to the rotation of the conductive piece 11. This resistance needs to be greater than the elastic force of the second spring 14.

[0034] Then, when the movable column 15 slides to its maximum displacement under the length limit of the slide groove 17, the outer wall of the end of the conductive column 13 just contacts the conical surface of the insertion column 6. At this time, the insertion column 6 is pushed, and the insertion column 6 begins to push the conductive column 13 at the same angle to expand outward. The conductive seat 8 slides on the outer wall of the fixed frame 7 and squeezes the first spring 9 until the horizontal arc surface of the outer wall of the conductive column 13 moves and fits against the cylindrical surface of the insertion column 6. The insertion of the connector socket 1 and the connector plug 2 can be completed. At this time, the movable column 15 is in a suspended state. Under the action of the second spring 14, the movable column 15 rotates by sliding the slide rod 16 in the slide groove 17. The rotation angle is also ninety degrees, and the conductive column 13 is in the state after rotating ninety degrees.

[0035] Finally, if the staff finds that the circuit is not connected after plugging in the connector socket 1 and the connector plug 2, they can unplug the connector plug 2 and reinsert it into the connector socket 1. The above process can be repeated so that the conductive post 13 rotates 90 degrees again in the same direction. Conductive power is achieved by the other horizontal arc surface of the conductive post 13 contacting the cylindrical surface of the plug 6. In case of poor contact, different horizontal arc surfaces of the conductive post 13 can be switched to make contact with the plug 6. If the circuit is still not connected after switching the horizontal arc surfaces, the outer surfaces of the conductive post 13 and the plug 6 can be cleaned or the connector core can be replaced or repaired. The conductive post 13 and the plug 6 are both exposed on the outside, which is convenient for cleaning the outer surface.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
