Description

Technical Field

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

[0002] In the field of power and electronic equipment connections, three-phase power connectors play a crucial role. Traditional three-phase power connectors typically use a fixed connection method, lacking sufficient stability and flexibility between the plug and socket. This leads to loosening or detachment during use, affecting the stable transmission of current and the normal operation of equipment. In addition, existing three-phase power connectors are often structurally complex, making installation and maintenance difficult, and they are prone to damage or wear during use, resulting in a short service life. Furthermore, some connectors also have certain deficiencies in conductivity and safety, making it difficult to meet the high reliability and safety requirements of modern electronic equipment. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a three-phase push-pull connector that is compact in structure, easy to operate, and safe and reliable.

[0004] To achieve the above objectives, this utility model employs a three-phase push-pull connector, comprising a housing with multiple receiving slots, each containing a copper head seat. A copper head is formed inside the copper head seat, extending beyond its outer surface. A conductive strip is provided between the back walls of the copper head seat, and a pluggable button is mounted on the conductive strip. An opening is provided in the housing corresponding to the button's position. A detachable cover is provided at one end of the copper head seat, inserted into the housing. A limiting strip is provided at one end of the cover and connected to the housing via a snap-fit. A back plate is mounted on one end of the housing corresponding to the copper head seat.

[0005] The advantages of the above structure are as follows: through the design of the receiving groove on the housing and the plug-in copper head socket, the entire connector structure is compact and reasonably laid out. The pluggable button on the conductive strip and the corresponding opening on the housing allow users to easily operate the button to control the circuit on and off. By pressing the button, the copper head can be released and the cover can be lowered. This one-button operation design makes the meter replacement process convenient and quick. The limit strip set in front of the button effectively prevents the cover from sliding down due to accidental button touch. After the meter is installed, the outlet position is tightly covered by the cover, which plays a role in preventing electricity theft.

[0006] This utility model further features a slot on one outer wall of the housing, with one end of the limiting strip snapping into the slot. A limiting block is formed on the other outer wall of the housing, and the other end of the limiting strip has a matching limiting groove corresponding to the limiting block. The slot and limiting strip snapping design enhances the connection stability between the cover and the housing, making the connector more reliable during use. The cooperation between the limiting block and the limiting groove effectively prevents the cover from accidentally falling off or misaligning due to external forces, further improving the safety and stability of the connector.

[0007] This utility model is further configured to have at least one cable outlet on the copper head socket for connecting cables. By providing at least one cable outlet on the copper head socket, cables can be easily connected to the copper head socket without the need for additional connectors or tools, thus simplifying the electrical connection process.

[0008] This utility model further features an interference fit copper tip with a nickel plating layer on its surface. The interference fit design ensures a tight fit between the copper tip and the tip holder, thereby improving the stability and reliability of the electrical connection. The nickel plating layer on the copper tip provides additional protection, enhancing its corrosion resistance and wear resistance. Attached Figure Description

[0018] like Figures 1-9 As shown, an embodiment of this utility model provides a three-phase push-pull connector. The housing 1 has seven receiving slots 11, each containing a copper head seat 2. The six copper head seats 2 are divided into three groups. Each copper head seat 2 has a copper head 21 formed inside, with the copper head 21 extending beyond the outer surface. The back walls of two copper head seats 2 in each group are connected by a conductive strip 3. The conductive strip 3 has a pluggable button 4. The housing 1 has openings 12 corresponding to the positions of the buttons 4 for the buttons to extend. The last copper head seat 2 has a different structure from the other six; it is larger and has a button 4 on one side. Furthermore, this copper head seat 2 has four cable outlets 22, while the other six copper head seats 2 only have two cable outlets 21. A cover 5 is inserted into the housing 1, and its front end has a limiting strip 6, which is connected to the housing 1 by a buckle 61. On the housing 1, a slot 13 is provided on one side of the outer wall. One end of the limiting strip 6 is snapped 61 in the slot 13. A limiting block 14 is provided on the other side of the outer wall. The other end of the limiting strip 6 is provided with a matching limiting groove 62 corresponding to the limiting block 14. A back plate 7 is installed on one end of the housing 1 corresponding to the copper head seat 2. In addition, it is worth noting that all the copper heads 21 in the copper head seats 2 adopt an interference fit design to ensure a tight fit between the copper head 21 and the copper head seat 2. At the same time, the surface of the copper head 21 is also plated with a layer of nickel, which not only provides additional protection, but also significantly enhances the corrosion resistance and wear resistance of the copper head. Among them, except for the last cover 5, the structure of the other three sets of cover 5 is the same, while the structure of the last cover 5 is different from the other six to adapt to the special size and functional requirements of its corresponding copper head seat 2.

[0019] Of course, in addition to the above embodiments, this utility model may have other various embodiments. Without departing from the essential technical solution of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, and these changes or modifications are equivalent to the technical solution in this patent. Therefore, these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model, and the utility model creation is in line with the applicant's actual R&D capabilities and resource conditions.
