Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to a composite material connector. Background Technology

[0002] Electrical connectors are indispensable products for electrical connection or signal transmission between circuit units of a system or complete machine. In addition to meeting general performance requirements, electrical connectors must meet the following requirements: good contact, reliable operation, and convenient maintenance. Their reliability directly affects the normal operation of the entire circuit and involves the safety of the entire machine.

[0003] In existing technologies, electrical connectors typically have only one-piece molded copper connecting sleeves inside the sockets. Circuit connections are formed through the copper connecting sleeves and pins inserted into them. However, the conductivity and corrosion resistance of the copper connecting sleeves are not excellent, resulting in relatively low reliability of the electrical connectors.

[0004] Therefore, it is necessary to propose a composite material connector to enhance the reliability of electrical connectors, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a composite material connector, which aims to solve the problem that in the prior art, electrical connectors generally only have an integrally formed copper connecting sleeve in the socket, and the circuit connection is formed by the copper connecting sleeve and the pin inserted into the copper connecting sleeve. However, the conductivity and corrosion resistance of the copper connecting sleeve are not excellent, resulting in the reliability of the electrical connector not being particularly high.

[0006] To achieve the above objectives, this application proposes a composite material connector, comprising: a socket; a insert disposed within the socket; an insulator disposed within the insert, the insulator having a socket hole; a multi-lobed connector disposed at one end of the socket, the multi-lobed connector including a copper base layer and a gold plating layer; and a connector disposed within the socket, the multi-lobed connector being connected to the connector.

[0007] In some embodiments, the device further includes: a mounting platform disposed on the outer peripheral surface of the socket; and mounting holes spaced apart on the mounting platform.

[0008] In some embodiments, the device further includes: an external threaded section, the socket including the external threaded section; and an abutment platform disposed on the mounting platform, the abutment platform having an abutment surface.

[0009] In some embodiments, it further includes an abutment groove disposed on the abutment surface.

[0010] In some embodiments, it further includes: a plug disposed at the other end of the socket and connected to the connector; a limiting block screwed to the socket; and an annular groove disposed on the outer peripheral surface of the socket.

[0011] In some embodiments, it further includes: a locking member, which is screwed to the socket and abuts against the limiting block.

[0012] This application proposes a composite material connector, comprising: a socket; a sleeve disposed within the socket; an insulator disposed within the sleeve, the insulator having a socket hole; a multi-lobed connector disposed at one end of the socket hole, the multi-lobed connector including a copper base layer and a gold plating layer; and a connector disposed within the socket hole, the multi-lobed connector being connected to the connector. During the process of forming an electrical connection between the composite material connector and a male electrical component connector with pins, the pins of the male electrical component connector need to be inserted into the multi-lobed connector. The area of ​​the socket hole formed by the multi-lobed connector is slightly smaller than the cross-sectional area of ​​the pins. During pin insertion, the multi-lobed connector undergoes a slight outward expansion deformation, thereby making the connection between the connector and the pins more stable. The gold plating layer on the copper base layer of the connector effectively enhances the conductivity and corrosion resistance of the connector, as well as its wear resistance and signal transmission stability, which is beneficial for enhancing the stability of the connection between the composite material connector and the male electrical component connector.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application proposes a composite material connector, including: a socket 1; a plug 4 disposed inside the socket 1; an insulator 7 disposed inside the plug 4, and having a socket hole on the insulator 7; a multi-lobed connector 3 disposed at one end of the socket hole, the multi-lobed connector 3 including a copper base layer 31 and a gold plating layer 32; and a connector 13 disposed inside the socket hole, the multi-lobed connector 3 being connected to the connector 13.

[0025] The socket 1 is the structural foundation of a composite material connector, and all other structures in the connector are directly or indirectly mounted on the socket 1. The socket 1 has a large-diameter section and a small-diameter section. A insert 4 is installed within the large-diameter section of the socket 1, and the insert 4 has a mounting through-hole with an inner diameter larger than that of the small-diameter section. The insulator 7 includes a large-diameter section and a small-diameter section; the large-diameter section is installed within the small-diameter section, and the small-diameter section is installed within the mounting through-hole. The insulator 7 has a through-hole. The multi-lobed connector 3 is a core component of the composite material connector. The multi-lobed connector 3 forms an electrical connection with the pins inserted into it. The multi-lobed connector 3 is connected to the connector body 13. In the circuit system, the pins inserted into the multi-lobed connector 3 are connected to one electrical component, and the connector body 13 is connected to another electrical component, thus forming a connection between the two electrical components. The area of ​​the socket formed by the multi-lobed connector 3 is slightly smaller than the cross-sectional area of ​​the pin. When the pin is inserted into the multi-lobed connector 3, the multi-lobed connector 3 is expanded. At this time, the electrical connection between the pin and the multi-lobed connector 3 is reliable. The gold plating layer 32 on the copper base layer 31 can enhance the conductivity and corrosion resistance of the connector 3, as well as enhance the wear resistance and signal transmission stability of the connector 3.

[0026] Specifically, during the electrical connection process between the composite material connector and the male connector of the electrical component with pins, the pins of the male connector need to be inserted into the multi-lobed connector 3. The area of ​​the socket formed by the multi-lobed connector 3 is slightly smaller than the cross-sectional area of ​​the pin. During the pin insertion process, the multi-lobed connector 3 undergoes a slight outward expansion deformation, thereby making the connection between the connector 3 and the pin more stable. The gold plating layer 32 on the copper base layer 31 of the connector 3 effectively enhances the conductivity and corrosion resistance of the connector 3, as well as its wear resistance and signal transmission stability, thus improving the stability of the connection between the composite material connector and the male connector of the electrical component.

[0027] Preferably, the insulator 7 is provided with multiple sockets, and the multiple socket heads are provided with connectors 3 and connectors 13. The electrical component male connector is provided with multiple matching pins. The electrical component male connector also includes a cylindrical body, which is used to insert between the plug cylinder 4 and the insulator 7 to improve the stability of the connection between the composite material connector and the electrical component male connector. The cylindrical body is provided with an anti-rotation groove, and the plug cylinder 4 is provided with a matching anti-rotation protrusion 5. The relative angle between the electrical component male connector and the composite material connector is ensured by the cooperation of the anti-rotation protrusion 5 and the anti-rotation groove.

[0028] Preferably, the end of the plug 4 is provided with a guide surface 41 for guiding the body of the electrical component male connector, so that the electrical component male connector can be better inserted into the plug 4.

[0029] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes: a mounting platform 9, which is disposed on the outer peripheral surface of the socket 1; and mounting holes 91, which are spaced apart on the mounting platform 9. The design of the mounting platform 9 and the mounting holes 91 on the mounting platform 9 is beneficial for installing the socket 1 onto external components, thereby fixing the socket 1 and ensuring the stability of the composite material connector.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, it further includes: an external thread section 2, the socket 1 including the external thread section 2; the electrical component male connector is also provided with a connecting sleeve 14, after the pin is inserted into the multi-lobed connector 3, the connecting sleeve 14 is screwed onto the external thread section 2 of the socket 1, realizing a stable connection between the electrical component male connector and the composite material connector, ensuring the stability of the connection between the electrical component male connector and the composite material connector. An abutment platform is provided on the mounting platform 9, and the abutment platform is provided with an abutment surface. The abutment platform is used to abut against the connecting sleeve 14. When the connecting sleeve 14 abuts against the abutment platform, it is determined that the connecting sleeve 14 has been screwed into place. Through the friction between the connecting sleeve 14 and the abutment platform, the connecting sleeve 14 can also be locked, preventing the position of the connecting sleeve 14 from becoming loose.

[0031] See Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, it further includes an abutment groove 10, which is disposed on the abutment surface. The size of the abutment groove 10 is adapted to the connecting sleeve 14. When the connecting sleeve 14 is screwed into the abutment groove 10, both the inner and outer walls of the connecting sleeve 14 contact the groove wall of the abutment groove 10. It is determined that the connecting sleeve 14 has been screwed into the abutment groove 10 and abuts against the bottom wall of the groove 10. By providing the abutment groove 10, the contact area between the connecting sleeve 14 and the abutment surface can be increased to better lock the position of the connecting sleeve 14.

[0032] In this embodiment, an adhesive can also be provided inside the abutment groove 10 to lock the connecting sleeve 14, thereby enhancing the reliability of the connection between the male connector of the electrical connector and the composite material connector. The outer peripheral surface of the connecting sleeve 14 is provided with straight knurling, which facilitates the operator to tighten the connecting sleeve 14.

[0033] See Figure 1 , Figure 3 and Figure 5As shown, in some embodiments, it further includes: a plug 6, which is disposed at the other end of the socket and connected to the connector 13; the plug 6 is used to insert into the electrical component female connector, which is provided with an insertion hole adapted to the plug 6; a small-diameter section of the insulator 7 extends out of the socket 1, and during the insertion of the plug 6 into the electrical component female connector, the small-diameter section extending out of the socket 1 is also inserted into the electrical component female connector, and the small-diameter section extending out of the socket 1 is provided with an anti-rotation groove; a limiting block 8, which is screwed to the socket 1; and an annular groove 12, which is disposed on the outer peripheral surface of the socket 1. Since after the plug 6 is inserted into the female connector of the electrical component, it needs to be screwed onto the outer circumference of the female connector of the electrical component through a connecting nut to achieve a stable connection between the plug 6 and the female connector of the electrical component, when the connecting nut is fitted onto the end of the socket 1 where the plug 6 is located, the limiting block 8 is screwed on to restrict the degree of freedom of the connecting nut in one direction along the socket 1. When the connecting nut is screwed in place, the connecting nut abuts against the limiting surface 81 of the limiting block 8. At this time, a C-shaped retaining spring is inserted into the annular groove 12 to restrict the degree of freedom of the connecting nut in the other direction, so that the position of the connecting nut relative to the socket 1 is fixed. The fixing method of the connecting sleeve 14 on the male connector of the electrical component is the same as the above fixing method. Of course, other fixing methods can also be used, and no specific limitation is made here.

[0034] See Figure 3 As shown, in some embodiments, it further includes a locking member 11, which is screwed to the socket 1 and abuts against the limiting block 8. The position of the limiting block 8 is locked by the friction between the locking member 11 and the socket 1 to prevent the limiting block 8 from becoming loose.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
